-# Embucket Benchmarks
-
-This crate contains benchmarks based on popular public data sets and
-open source benchmark suites, to help with performance and scalability
-testing of DataFusion.
-
-# Running the benchmarks
-
-## `bench.sh`
-
-The easiest way to run benchmarks is the [bench.sh](bench.sh)
-script. Usage instructions can be found with:
-
-```shell
-# show usage
-cd ./benchmarks/
-./bench.sh
-```
-
-## Generating data
-
-You can create / download the data for these benchmarks using the [bench.sh](bench.sh) script:
-
-Create / download all datasets
-
-```shell
-./bench.sh data
-```
-
-Create / download a specific dataset (TPCH)
-
-```shell
-./bench.sh data tpch
-```
-Data is placed in the `data` subdirectory.
-
-## Running benchmarks
-
-Run benchmark for TPC-H dataset
-```shell
-./bench.sh run tpch
-```
-or for TPC-H dataset scale 10
-```shell
-./bench.sh run tpch10
-```
-
-To run for specific query, for example Q21
-```shell
-./bench.sh run tpch10 21
-```
-
-## Comparing performance of main and a branch
-
-```shell
-git checkout main
-
-# Create the data
-./benchmarks/bench.sh data tpch
-
-# Gather baseline data for tpch benchmark
-./benchmarks/bench.sh run tpch
-
-# Switch to the branch named mybranch and gather data
-git checkout mybranch
-./benchmarks/bench.sh run tpch
-
-# Compare results in the two branches:
-./bench.sh compare main mybranch
-```
-
-This produces results like:
-
-```shell

-## Comparing datafusion and embucket performance
-
-```shell
-git checkout main
-
-# Create the data
-./benchmarks/bench.sh data
-RESULTS_NAME=datafusion ./benchmarks/bench.sh run dftpch
-RESULTS_NAME=embucket ./benchmarks/bench.sh run tpch
-
-# Compare results in the two branches:
-./bench.sh compare datafusion embucket
-```
-
-### Running Benchmarks Manually
-
-Assuming data is in the `data` directory, the `tpch` benchmark can be run with a command like this:
-
-```bash
-# Run embucket tpch benchmark
-cargo run --release --bin embench -- tpch --iterations 3 --path ./data  --query 1
-# Run datafusion tpch benchmark
-cargo run --release --bin embench -- tpch --datafusion --path benchmarks/data/tpch_sf10 --partitions 2 --format parquet --query 18 --iterations=1 --memory-limit 150M --debug --batch-size 8192 --prefer_hash_join true --mem-pool-type fair
-```
-
-### Different features
-
-You can enable `mimalloc` or `snmalloc` (to use either the mimalloc or snmalloc allocator) as features by passing them in as `--features`. For example:
-
-```shell
-cargo run --release --features "mimalloc" --bin embench -- tpch --iterations 3 --path ./data --query 1
-```
-
-# Writing a new benchmark
-
-## Creating or downloading data outside of the benchmark
-
-If you want to create or download the data with Rust as part of running the benchmark, see the next
-section on adding a benchmark subcommand and add code to create or download data as part of its
-`run` function.
-
-If you want to create or download the data with shell commands, in `benchmarks/bench.sh`, define a
-new function named `data_[your benchmark name]` and call that function in the `data` command case
-as a subcommand case named for your benchmark. Also call the new function in the `data all` case.
-
-## Adding the benchmark subcommand
-
-In `benchmarks/bench.sh`, define a new function named `run_[your benchmark name]` following the
-example of existing `run_*` functions. Call that function in the `run` command case as a subcommand
-case named for your benchmark. subcommand for your benchmark. Also call the new function in the
-`run all` case. Add documentation for your benchmark to the text in the `usage` function.
-
-### Creating or downloading data as part of the benchmark
-
-Use the `--path` structopt field defined on the `RunOpt` struct to know where to store or look for
-the data. Generate the data using whatever Rust code you'd like, before the code that will be
-measuring an operation.
-
-### Collecting data
-
-Your benchmark should create and use an instance of `BenchmarkRun` defined in `benchmarks/src/util/run.rs` as follows:
-
-- Call its `start_new_case` method with a string that will appear in the "Query" column of the
-  compare output.
-- Use `write_iter` to record elapsed times for the behavior you're benchmarking.
-- When all cases are done, call the `BenchmarkRun`'s `maybe_write_json` method, giving it the value
-  of the `--output` structopt field on `RunOpt`.

-# ClickBench queries
-
-This directory contains queries for the ClickBench benchmark https://benchmark.clickhouse.com/
-
-ClickBench is focused on aggregation and filtering performance (though it has no Joins)
-
-## Files:
-* `queries.sql` - Actual ClickBench queries, downloaded from the [ClickBench repository]
-* `extended.sql` - "Extended" DataFusion specific queries. 
-
-[ClickBench repository]: https://github.com/ClickHouse/ClickBench/blob/main/datafusion/queries.sql
-
-## "Extended" Queries 
-
-The "extended" queries are not part of the official ClickBench benchmark.
-Instead they are used to test other DataFusion features that are not covered by
-the standard benchmark. Each description below is for the corresponding line in
-`extended.sql` (line 1 is `Q0`, line 2 is `Q1`, etc.)
-
-### Q0: Data Exploration
-
-**Question**: "How many distinct searches, mobile phones, and mobile phone models are there in the dataset?"
-
-**Important Query Properties**: multiple `COUNT DISTINCT`s, with low and high cardinality
-distinct string columns.
-
-```sql
-SELECT COUNT(DISTINCT "SearchPhrase"), COUNT(DISTINCT "MobilePhone"), COUNT(DISTINCT "MobilePhoneModel") 
-FROM hits;
-```
-
-### Q1: Data Exploration
-
-**Question**: "How many distinct "hit color", "browser country" and "language" are there in the dataset?"
-
-**Important Query Properties**: multiple `COUNT DISTINCT`s. All three are small strings (length either 1 or 2).
-
-
-```sql
-SELECT COUNT(DISTINCT "HitColor"), COUNT(DISTINCT "BrowserCountry"), COUNT(DISTINCT "BrowserLanguage")
-FROM hits;
-```
-
-### Q2: Top 10 analysis
-
-**Question**: "Find the top 10 "browser country" by number of distinct "social network"s, 
-including the distinct counts of  "hit color", "browser language",
-and "social action"."
-
-**Important Query Properties**: GROUP BY short, string, multiple `COUNT DISTINCT`s. There are several small strings (length either 1 or 2).
-
-```sql
-SELECT "BrowserCountry",  COUNT(DISTINCT "SocialNetwork"), COUNT(DISTINCT "HitColor"), COUNT(DISTINCT "BrowserLanguage"), COUNT(DISTINCT "SocialAction")
-FROM hits 
-GROUP BY 1 
-ORDER BY 2 DESC 
-LIMIT 10;
-```
-
-
-### Q3: What is the income distribution for users in specific regions
-
-**Question**: "What regions and social networks have the highest variance of parameter price?"
-
-**Important Query Properties**: STDDEV and VAR aggregation functions, GROUP BY multiple small ints
-
-```sql
-SELECT "SocialSourceNetworkID", "RegionID", COUNT(*), AVG("Age"), AVG("ParamPrice"), STDDEV("ParamPrice") as s, VAR("ParamPrice") 
-FROM 'hits.parquet' 
-GROUP BY "SocialSourceNetworkID", "RegionID"  
-HAVING s IS NOT NULL
-ORDER BY s DESC 
-LIMIT 10;
-```
-
-### Q4: Response start time distribution analysis (median)
-
-**Question**:  Find the WatchIDs with the highest median "ResponseStartTiming" without Java enabled
-
-**Important Query Properties**: MEDIAN, functions, high cardinality grouping that skips intermediate aggregation
-
-Note this query is somewhat synthetic as "WatchID" is almost unique (there are a few duplicates)
-
-```sql
-SELECT "ClientIP", "WatchID",  COUNT(*) c, MIN("ResponseStartTiming") tmin, MEDIAN("ResponseStartTiming") tmed, MAX("ResponseStartTiming") tmax
-FROM 'hits.parquet'
-WHERE "JavaEnable" = 0 -- filters to 32M of 100M rows
-GROUP BY  "ClientIP", "WatchID"
-HAVING c > 1
-ORDER BY tmed DESC
-LIMIT 10;
-```
-
-Results look like
-
-```
-+-------------+---------------------+---+------+------+------+
-| ClientIP    | WatchID             | c | tmin | tmed | tmax |
-+-------------+---------------------+---+------+------+------+
-| 1611957945  | 6655575552203051303 | 2 | 0    | 0    | 0    |
-| -1402644643 | 8566928176839891583 | 2 | 0    | 0    | 0    |
-+-------------+---------------------+---+------+------+------+
-```
-
-
-### Q5: Response start time distribution analysis (p95)
-
-**Question**:  Find the WatchIDs with the highest p95 "ResponseStartTiming" without Java enabled
-
-**Important Query Properties**: APPROX_PERCENTILE_CONT, functions, high cardinality grouping that skips intermediate aggregation
-
-Note this query is somewhat synthetic as "WatchID" is almost unique (there are a few duplicates)
-
-```sql
-SELECT "ClientIP", "WatchID",  COUNT(*) c, MIN("ResponseStartTiming") tmin, APPROX_PERCENTILE_CONT("ResponseStartTiming", 0.95) tp95, MAX("ResponseStartTiming") tmax
-FROM 'hits.parquet'
-WHERE "JavaEnable" = 0 -- filters to 32M of 100M rows
-GROUP BY  "ClientIP", "WatchID"
-HAVING c > 1
-ORDER BY tp95 DESC
-LIMIT 10;
-```
-
-Results look like
-```
-+-------------+---------------------+---+------+------+------+
-| ClientIP    | WatchID             | c | tmin | tp95 | tmax |
-+-------------+---------------------+---+------+------+------+
-| 1611957945  | 6655575552203051303 | 2 | 0    | 0    | 0    |
-| -1402644643 | 8566928176839891583 | 2 | 0    | 0    | 0    |
-+-------------+---------------------+---+------+------+------+
-```
-
-### Q6: How many social shares meet complex multi-stage filtering criteria?
-**Question**: What is the count of sharing actions from iPhone mobile users on specific social networks, within common timezones, participating in seasonal campaigns, with high screen resolutions and closely matched UTM parameters?
-**Important Query Properties**: Simple filter with high-selectivity, Costly string matching, A large number of filters with high overhead are positioned relatively later in the process
-
-```sql
-SELECT COUNT(*) AS ShareCount
-FROM hits
-WHERE
-	-- Stage 1: High-selectivity filters (fast)
-    "IsMobile" = 1 -- Filter mobile users
-    AND "MobilePhoneModel" LIKE 'iPhone%' -- Match iPhone models
-    AND "SocialAction" = 'share' -- Identify social sharing actions
-
-	-- Stage 2: Moderate filters (cheap)
-    AND "SocialSourceNetworkID" IN (5, 12) -- Filter specific social networks
-    AND "ClientTimeZone" BETWEEN -5 AND 5 -- Restrict to common timezones
-
-	-- Stage 3: Heavy computations (expensive)
-    AND regexp_match("Referer", '\/campaign\/(spring|summer)_promo') IS NOT NULL -- Find campaign-specific referrers
-    AND CASE 
-        WHEN split_part(split_part("URL", 'resolution=', 2), '&', 1) ~ '^\d+$' 
-        THEN split_part(split_part("URL", 'resolution=', 2), '&', 1)::INT 
-        ELSE 0 
-    END > 1920 -- Extract and validate resolution parameter
-    AND levenshtein(CAST("UTMSource" AS STRING), CAST("UTMCampaign" AS STRING)) < 3 -- Verify UTM parameter similarity
-```
-Result is empty,Since it has already been filtered by `"SocialAction" = 'share'`.
-
-
-## Data Notes
-
-Here are some interesting statistics about the data used in the queries
-Max length of `"SearchPhrase"` is 1113 characters
-```sql
-> select min(length("SearchPhrase")) as "SearchPhrase_len_min", max(length("SearchPhrase")) "SearchPhrase_len_max" from 'hits.parquet' limit 10;
-+----------------------+----------------------+
-| SearchPhrase_len_min | SearchPhrase_len_max |
-+----------------------+----------------------+
-| 0                    | 1113                 |

-## E2E tests
-
-`cargo e2e` command runs all e2e tests.
-
-### Prerequisites
-
-Should set envs, please check at the repository root `.env_e2e` file that contains the list ov vars needed to be set.
-
-Some of tests may require toxiproxy, some allow to use MinIO, and some require pure AWS for s3, s3tables buckets.
-
-Use following to run toxiproxy and MinIO docker containers:
-```
-docker run --rm --net=host --name toxiproxy -it ghcr.io/shopify/toxiproxy
-
-docker run -d --rm --name minio -p 9001:9001 -p 9000:9000 -e MINIO_ROOT_USER=minioadmin -e MINIO_ROOT_PASSWORD=minioadmin minio/minio server --console-address :9001 ${PWD}/minio-data
-```

 This crate provides a consistent way for other Embucket components to access and manipulate metadata about catalogs, schemas, tables, and other entities, abstracting the specific storage backend.
+
+### Using Sqlite based Metastore with Diesel ORM
+
+Find Diesel config in `diesel.toml` file. 
+
+To run migrations use:
+
+```bash
+# run migrations (for first time it creates database tables)
+    diesel migration run --database-url "file:sqlite_data/metastore.db"

-`sqlite-plugin` provides a streamlined and flexible way to implement SQLite virtual file systems (VFS) in Rust. Inspired by [sqlite-vfs], it offers a distinct design with key enhancements:
-
-- **Centralized Control**: The `Vfs` trait intercepts all file operations at the VFS level, rather than delegating them directly to file handles. This simplifies shared state management and enables more advanced behaviors.
-- **Custom Pragmas**: Easily define and handle custom SQLite pragmas to extend database functionality.
-- **Integrated Logging**: Seamlessly forward logs to SQLite’s built-in logging system for unified diagnostics.

-** that allows an application to run multiple statements of SQL
-** without having to use a lot of C code.
-**
-** ^The sqlite3_exec() interface runs zero or more UTF-8 encoded,

-** in the context of the [database connection] passed in as its 1st
-** argument.  ^If the callback function of the 3rd argument to
-** sqlite3_exec() is not NULL, then it is invoked for each result row
-** coming out of the evaluated SQL statements.  ^The 4th argument to
-** sqlite3_exec() is relayed through to the 1st argument of each
-** callback invocation.  ^If the callback pointer to sqlite3_exec()
-** is NULL, then no callback is ever invoked and result rows are
-** ignored.
-**
-** ^If an error occurs while evaluating the SQL statements passed into
-** sqlite3_exec(), then execution of the current statement stops and
-** subsequent statements are skipped.  ^If the 5th parameter to sqlite3_exec()
-** is not NULL then any error message is written into memory obtained
-** from [sqlite3_malloc()] and passed back through the 5th parameter.
-** To avoid memory leaks, the application should invoke [sqlite3_free()]
-** on error message strings returned through the 5th parameter of
-** sqlite3_exec() after the error message string is no longer needed.
-** ^If the 5th parameter to sqlite3_exec() is not NULL and no errors
-** occur, then sqlite3_exec() sets the pointer in its 5th parameter to
-** NULL before returning.
-**
-** ^If an sqlite3_exec() callback returns non-zero, the sqlite3_exec()
-** routine returns SQLITE_ABORT without invoking the callback again and
-** without running any subsequent SQL statements.
-**
-** ^The 2nd argument to the sqlite3_exec() callback function is the
-** number of columns in the result.  ^The 3rd argument to the sqlite3_exec()
-** callback is an array of pointers to strings obtained as if from
-** [sqlite3_column_text()], one for each column.  ^If an element of a
-** result row is NULL then the corresponding string pointer for the
-** sqlite3_exec() callback is a NULL pointer.  ^The 4th argument to the
-** sqlite3_exec() callback is an array of pointers to strings where each
-** entry represents the name of corresponding result column as obtained
-** from [sqlite3_column_name()].
-**
-** ^If the 2nd parameter to sqlite3_exec() is a NULL pointer, a pointer

-** CAPI3REF: Extended Result Codes

-**
-** In its default configuration, SQLite API routines return one of 30 integer
-** [result codes].  However, experience has shown that many of
-** these result codes are too coarse-grained.  They do not provide as
-** much information about problems as programmers might like.  In an effort to
-** address this, newer versions of SQLite (version 3.3.8 [dateof:3.3.8]
-** and later) include
-** support for additional result codes that provide more detailed information
-** about errors. These [extended result codes] are enabled or disabled
-** on a per database connection basis using the
-** [sqlite3_extended_result_codes()] API.  Or, the extended code for
-** the most recent error can be obtained using
-** [sqlite3_extended_errcode()].

-** CAPI3REF: OS Interface File Virtual Methods Object
-**
-** Every file opened by the [sqlite3_vfs.xOpen] method populates an
-** [sqlite3_file] object (or, more commonly, a subclass of the
-** [sqlite3_file] object) with a pointer to an instance of this object.
-** This object defines the methods used to perform various operations
-** against the open file represented by the [sqlite3_file] object.
-**
-** If the [sqlite3_vfs.xOpen] method sets the sqlite3_file.pMethods element
-** to a non-NULL pointer, then the sqlite3_io_methods.xClose method
-** may be invoked even if the [sqlite3_vfs.xOpen] reported that it failed.  The
-** only way to prevent a call to xClose following a failed [sqlite3_vfs.xOpen]
-** is for the [sqlite3_vfs.xOpen] to set the sqlite3_file.pMethods element
-** to NULL.
-**
-** The flags argument to xSync may be one of [SQLITE_SYNC_NORMAL] or
-** [SQLITE_SYNC_FULL].  The first choice is the normal fsync().
-** The second choice is a Mac OS X style fullsync.  The [SQLITE_SYNC_DATAONLY]
-** flag may be ORed in to indicate that only the data of the file
-** and not its inode needs to be synced.
-**
-** The integer values to xLock() and xUnlock() are one of
-** <ul>
-** <li> [SQLITE_LOCK_NONE],
-** <li> [SQLITE_LOCK_SHARED],
-** <li> [SQLITE_LOCK_RESERVED],
-** <li> [SQLITE_LOCK_PENDING], or
-** <li> [SQLITE_LOCK_EXCLUSIVE].
-** </ul>
-** xLock() upgrades the database file lock.  In other words, xLock() moves the
-** database file lock in the direction NONE toward EXCLUSIVE. The argument to
-** xLock() is always one of SHARED, RESERVED, PENDING, or EXCLUSIVE, never
-** SQLITE_LOCK_NONE.  If the database file lock is already at or above the
-** requested lock, then the call to xLock() is a no-op.
-** xUnlock() downgrades the database file lock to either SHARED or NONE.
-** If the lock is already at or below the requested lock state, then the call
-** to xUnlock() is a no-op.
-** The xCheckReservedLock() method checks whether any database connection,
-** either in this process or in some other process, is holding a RESERVED,
-** PENDING, or EXCLUSIVE lock on the file.  It returns true
-** if such a lock exists and false otherwise.
-**
-** The xFileControl() method is a generic interface that allows custom
-** VFS implementations to directly control an open file using the
-** [sqlite3_file_control()] interface.  The second "op" argument is an
-** integer opcode.  The third argument is a generic pointer intended to
-** point to a structure that may contain arguments or space in which to
-** write return values.  Potential uses for xFileControl() might be
-** functions to enable blocking locks with timeouts, to change the
-** locking strategy (for example to use dot-file locks), to inquire
-** about the status of a lock, or to break stale locks.  The SQLite
-** core reserves all opcodes less than 100 for its own use.
-** A [file control opcodes | list of opcodes] less than 100 is available.
-** Applications that define a custom xFileControl method should use opcodes
-** greater than 100 to avoid conflicts.  VFS implementations should
-** return [SQLITE_NOTFOUND] for file control opcodes that they do not
-** recognize.
-**
-** The xSectorSize() method returns the sector size of the
-** device that underlies the file.  The sector size is the
-** minimum write that can be performed without disturbing
-** other bytes in the file.  The xDeviceCharacteristics()
-** method returns a bit vector describing behaviors of the
-** underlying device:

-** CAPI3REF: Standard File Control Opcodes
-** KEYWORDS: {file control opcodes} {file control opcode}
-**
-** These integer constants are opcodes for the xFileControl method
-** of the [sqlite3_io_methods] object and for the [sqlite3_file_control()]
-** interface.
-**
-** <ul>
-** <li>[[SQLITE_FCNTL_LOCKSTATE]]
-** The [SQLITE_FCNTL_LOCKSTATE] opcode is used for debugging.  This
-** opcode causes the xFileControl method to write the current state of
-** the lock (one of [SQLITE_LOCK_NONE], [SQLITE_LOCK_SHARED],
-** [SQLITE_LOCK_RESERVED], [SQLITE_LOCK_PENDING], or [SQLITE_LOCK_EXCLUSIVE])
-** into an integer that the pArg argument points to.
-** This capability is only available if SQLite is compiled with [SQLITE_DEBUG].
-**
-** <li>[[SQLITE_FCNTL_SIZE_HINT]]
-** The [SQLITE_FCNTL_SIZE_HINT] opcode is used by SQLite to give the VFS
-** layer a hint of how large the database file will grow to be during the
-** current transaction.  This hint is not guaranteed to be accurate but it
-** is often close.  The underlying VFS might choose to preallocate database
-** file space based on this hint in order to help writes to the database
-** file run faster.
-**
-** <li>[[SQLITE_FCNTL_SIZE_LIMIT]]
-** The [SQLITE_FCNTL_SIZE_LIMIT] opcode is used by in-memory VFS that
-** implements [sqlite3_deserialize()] to set an upper bound on the size
-** of the in-memory database.  The argument is a pointer to a [sqlite3_int64].
-** If the integer pointed to is negative, then it is filled in with the
-** current limit.  Otherwise the limit is set to the larger of the value
-** of the integer pointed to and the current database size.  The integer
-** pointed to is set to the new limit.
-**
-** <li>[[SQLITE_FCNTL_CHUNK_SIZE]]
-** The [SQLITE_FCNTL_CHUNK_SIZE] opcode is used to request that the VFS
-** extends and truncates the database file in chunks of a size specified
-** by the user. The fourth argument to [sqlite3_file_control()] should
-** point to an integer (type int) containing the new chunk-size to use
-** for the nominated database. Allocating database file space in large
-** chunks (say 1MB at a time), may reduce file-system fragmentation and
-** improve performance on some systems.
-**
-** <li>[[SQLITE_FCNTL_FILE_POINTER]]
-** The [SQLITE_FCNTL_FILE_POINTER] opcode is used to obtain a pointer
-** to the [sqlite3_file] object associated with a particular database
-** connection.  See also [SQLITE_FCNTL_JOURNAL_POINTER].
-**
-** <li>[[SQLITE_FCNTL_JOURNAL_POINTER]]
-** The [SQLITE_FCNTL_JOURNAL_POINTER] opcode is used to obtain a pointer
-** to the [sqlite3_file] object associated with the journal file (either
-** the [rollback journal] or the [write-ahead log]) for a particular database
-** connection.  See also [SQLITE_FCNTL_FILE_POINTER].
-**
-** <li>[[SQLITE_FCNTL_SYNC_OMITTED]]
-** No longer in use.
-**
-** <li>[[SQLITE_FCNTL_SYNC]]
-** The [SQLITE_FCNTL_SYNC] opcode is generated internally by SQLite and
-** sent to the VFS immediately before the xSync method is invoked on a
-** database file descriptor. Or, if the xSync method is not invoked
-** because the user has configured SQLite with
-** [PRAGMA synchronous | PRAGMA synchronous=OFF] it is invoked in place
-** of the xSync method. In most cases, the pointer argument passed with
-** this file-control is NULL. However, if the database file is being synced
-** as part of a multi-database commit, the argument points to a nul-terminated
-** string containing the transactions super-journal file name. VFSes that
-** do not need this signal should silently ignore this opcode. Applications
-** should not call [sqlite3_file_control()] with this opcode as doing so may
-** disrupt the operation of the specialized VFSes that do require it.
-**
-** <li>[[SQLITE_FCNTL_COMMIT_PHASETWO]]
-** The [SQLITE_FCNTL_COMMIT_PHASETWO] opcode is generated internally by SQLite
-** and sent to the VFS after a transaction has been committed immediately
-** but before the database is unlocked. VFSes that do not need this signal
-** should silently ignore this opcode. Applications should not call
-** [sqlite3_file_control()] with this opcode as doing so may disrupt the
-** operation of the specialized VFSes that do require it.
-**
-** <li>[[SQLITE_FCNTL_WIN32_AV_RETRY]]
-** ^The [SQLITE_FCNTL_WIN32_AV_RETRY] opcode is used to configure automatic
-** retry counts and intervals for certain disk I/O operations for the
-** windows [VFS] in order to provide robustness in the presence of
-** anti-virus programs.  By default, the windows VFS will retry file read,
-** file write, and file delete operations up to 10 times, with a delay
-** of 25 milliseconds before the first retry and with the delay increasing
-** by an additional 25 milliseconds with each subsequent retry.  This
-** opcode allows these two values (10 retries and 25 milliseconds of delay)
-** to be adjusted.  The values are changed for all database connections
-** within the same process.  The argument is a pointer to an array of two
-** integers where the first integer is the new retry count and the second
-** integer is the delay.  If either integer is negative, then the setting
-** is not changed but instead the prior value of that setting is written
-** into the array entry, allowing the current retry settings to be
-** interrogated.  The zDbName parameter is ignored.
-**
-** <li>[[SQLITE_FCNTL_PERSIST_WAL]]
-** ^The [SQLITE_FCNTL_PERSIST_WAL] opcode is used to set or query the
-** persistent [WAL | Write Ahead Log] setting.  By default, the auxiliary
-** write ahead log ([WAL file]) and shared memory
-** files used for transaction control
-** are automatically deleted when the latest connection to the database
-** closes.  Setting persistent WAL mode causes those files to persist after
-** close.  Persisting the files is useful when other processes that do not
-** have write permission on the directory containing the database file want
-** to read the database file, as the WAL and shared memory files must exist
-** in order for the database to be readable.  The fourth parameter to
-** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
-** That integer is 0 to disable persistent WAL mode or 1 to enable persistent
-** WAL mode.  If the integer is -1, then it is overwritten with the current
-** WAL persistence setting.
-**
-** <li>[[SQLITE_FCNTL_POWERSAFE_OVERWRITE]]
-** ^The [SQLITE_FCNTL_POWERSAFE_OVERWRITE] opcode is used to set or query the
-** persistent "powersafe-overwrite" or "PSOW" setting.  The PSOW setting
-** determines the [SQLITE_IOCAP_POWERSAFE_OVERWRITE] bit of the
-** xDeviceCharacteristics methods. The fourth parameter to
-** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
-** That integer is 0 to disable zero-damage mode or 1 to enable zero-damage
-** mode.  If the integer is -1, then it is overwritten with the current
-** zero-damage mode setting.
-**
-** <li>[[SQLITE_FCNTL_OVERWRITE]]
-** ^The [SQLITE_FCNTL_OVERWRITE] opcode is invoked by SQLite after opening
-** a write transaction to indicate that, unless it is rolled back for some
-** reason, the entire database file will be overwritten by the current
-** transaction. This is used by VACUUM operations.
-**
-** <li>[[SQLITE_FCNTL_VFSNAME]]
-** ^The [SQLITE_FCNTL_VFSNAME] opcode can be used to obtain the names of
-** all [VFSes] in the VFS stack.  The names are of all VFS shims and the
-** final bottom-level VFS are written into memory obtained from
-** [sqlite3_malloc()] and the result is stored in the char* variable
-** that the fourth parameter of [sqlite3_file_control()] points to.
-** The caller is responsible for freeing the memory when done.  As with
-** all file-control actions, there is no guarantee that this will actually
-** do anything.  Callers should initialize the char* variable to a NULL
-** pointer in case this file-control is not implemented.  This file-control
-** is intended for diagnostic use only.
-**
-** <li>[[SQLITE_FCNTL_VFS_POINTER]]
-** ^The [SQLITE_FCNTL_VFS_POINTER] opcode finds a pointer to the top-level
-** [VFSes] currently in use.  ^(The argument X in
-** sqlite3_file_control(db,SQLITE_FCNTL_VFS_POINTER,X) must be
-** of type "[sqlite3_vfs] **".  This opcodes will set *X
-** to a pointer to the top-level VFS.)^
-** ^When there are multiple VFS shims in the stack, this opcode finds the
-** upper-most shim only.
-**
-** <li>[[SQLITE_FCNTL_PRAGMA]]
-** ^Whenever a [PRAGMA] statement is parsed, an [SQLITE_FCNTL_PRAGMA]
-** file control is sent to the open [sqlite3_file] object corresponding
-** to the database file to which the pragma statement refers. ^The argument
-** to the [SQLITE_FCNTL_PRAGMA] file control is an array of
-** pointers to strings (char**) in which the second element of the array
-** is the name of the pragma and the third element is the argument to the
-** pragma or NULL if the pragma has no argument.  ^The handler for an
-** [SQLITE_FCNTL_PRAGMA] file control can optionally make the first element
-** of the char** argument point to a string obtained from [sqlite3_mprintf()]
-** or the equivalent and that string will become the result of the pragma or
-** the error message if the pragma fails. ^If the
-** [SQLITE_FCNTL_PRAGMA] file control returns [SQLITE_NOTFOUND], then normal
-** [PRAGMA] processing continues.  ^If the [SQLITE_FCNTL_PRAGMA]
-** file control returns [SQLITE_OK], then the parser assumes that the
-** VFS has handled the PRAGMA itself and the parser generates a no-op
-** prepared statement if result string is NULL, or that returns a copy
-** of the result string if the string is non-NULL.
-** ^If the [SQLITE_FCNTL_PRAGMA] file control returns
-** any result code other than [SQLITE_OK] or [SQLITE_NOTFOUND], that means
-** that the VFS encountered an error while handling the [PRAGMA] and the
-** compilation of the PRAGMA fails with an error.  ^The [SQLITE_FCNTL_PRAGMA]
-** file control occurs at the beginning of pragma statement analysis and so
-** it is able to override built-in [PRAGMA] statements.
-**
-** <li>[[SQLITE_FCNTL_BUSYHANDLER]]
-** ^The [SQLITE_FCNTL_BUSYHANDLER]
-** file-control may be invoked by SQLite on the database file handle
-** shortly after it is opened in order to provide a custom VFS with access
-** to the connection's busy-handler callback. The argument is of type (void**)
-** - an array of two (void *) values. The first (void *) actually points
-** to a function of type (int (*)(void *)). In order to invoke the connection's
-** busy-handler, this function should be invoked with the second (void *) in
-** the array as the only argument. If it returns non-zero, then the operation
-** should be retried. If it returns zero, the custom VFS should abandon the
-** current operation.
-**
-** <li>[[SQLITE_FCNTL_TEMPFILENAME]]
-** ^Applications can invoke the [SQLITE_FCNTL_TEMPFILENAME] file-control
-** to have SQLite generate a
-** temporary filename using the same algorithm that is followed to generate
-** temporary filenames for TEMP tables and other internal uses.  The
-** argument should be a char** which will be filled with the filename
-** written into memory obtained from [sqlite3_malloc()].  The caller should
-** invoke [sqlite3_free()] on the result to avoid a memory leak.
-**
-** <li>[[SQLITE_FCNTL_MMAP_SIZE]]
-** The [SQLITE_FCNTL_MMAP_SIZE] file control is used to query or set the
-** maximum number of bytes that will be used for memory-mapped I/O.
-** The argument is a pointer to a value of type sqlite3_int64 that
-** is an advisory maximum number of bytes in the file to memory map.  The
-** pointer is overwritten with the old value.  The limit is not changed if
-** the value originally pointed to is negative, and so the current limit
-** can be queried by passing in a pointer to a negative number.  This
-** file-control is used internally to implement [PRAGMA mmap_size].
-**
-** <li>[[SQLITE_FCNTL_TRACE]]
-** The [SQLITE_FCNTL_TRACE] file control provides advisory information
-** to the VFS about what the higher layers of the SQLite stack are doing.
-** This file control is used by some VFS activity tracing [shims].
-** The argument is a zero-terminated string.  Higher layers in the
-** SQLite stack may generate instances of this file control if
-** the [SQLITE_USE_FCNTL_TRACE] compile-time option is enabled.
-**
-** <li>[[SQLITE_FCNTL_HAS_MOVED]]
-** The [SQLITE_FCNTL_HAS_MOVED] file control interprets its argument as a
-** pointer to an integer and it writes a boolean into that integer depending
-** on whether or not the file has been renamed, moved, or deleted since it
-** was first opened.
-**
-** <li>[[SQLITE_FCNTL_WIN32_GET_HANDLE]]
-** The [SQLITE_FCNTL_WIN32_GET_HANDLE] opcode can be used to obtain the
-** underlying native file handle associated with a file handle.  This file
-** control interprets its argument as a pointer to a native file handle and
-** writes the resulting value there.
-**
-** <li>[[SQLITE_FCNTL_WIN32_SET_HANDLE]]
-** The [SQLITE_FCNTL_WIN32_SET_HANDLE] opcode is used for debugging.  This
-** opcode causes the xFileControl method to swap the file handle with the one
-** pointed to by the pArg argument.  This capability is used during testing
-** and only needs to be supported when SQLITE_TEST is defined.
-**
-** <li>[[SQLITE_FCNTL_WAL_BLOCK]]
-** The [SQLITE_FCNTL_WAL_BLOCK] is a signal to the VFS layer that it might
-** be advantageous to block on the next WAL lock if the lock is not immediately
-** available.  The WAL subsystem issues this signal during rare
-** circumstances in order to fix a problem with priority inversion.
-** Applications should <em>not</em> use this file-control.
-**
-** <li>[[SQLITE_FCNTL_ZIPVFS]]
-** The [SQLITE_FCNTL_ZIPVFS] opcode is implemented by zipvfs only. All other
-** VFS should return SQLITE_NOTFOUND for this opcode.
-**
-** <li>[[SQLITE_FCNTL_RBU]]
-** The [SQLITE_FCNTL_RBU] opcode is implemented by the special VFS used by
-** the RBU extension only.  All other VFS should return SQLITE_NOTFOUND for
-** this opcode.
-**
-** <li>[[SQLITE_FCNTL_BEGIN_ATOMIC_WRITE]]
-** If the [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] opcode returns SQLITE_OK, then
-** the file descriptor is placed in "batch write mode", which
-** means all subsequent write operations will be deferred and done
-** atomically at the next [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE].  Systems
-** that do not support batch atomic writes will return SQLITE_NOTFOUND.
-** ^Following a successful SQLITE_FCNTL_BEGIN_ATOMIC_WRITE and prior to
-** the closing [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE] or
-** [SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE], SQLite will make
-** no VFS interface calls on the same [sqlite3_file] file descriptor
-** except for calls to the xWrite method and the xFileControl method
-** with [SQLITE_FCNTL_SIZE_HINT].
-**
-** <li>[[SQLITE_FCNTL_COMMIT_ATOMIC_WRITE]]
-** The [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE] opcode causes all write
-** operations since the previous successful call to
-** [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] to be performed atomically.
-** This file control returns [SQLITE_OK] if and only if the writes were
-** all performed successfully and have been committed to persistent storage.
-** ^Regardless of whether or not it is successful, this file control takes
-** the file descriptor out of batch write mode so that all subsequent
-** write operations are independent.
-** ^SQLite will never invoke SQLITE_FCNTL_COMMIT_ATOMIC_WRITE without
-** a prior successful call to [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE].
-**
-** <li>[[SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE]]
-** The [SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE] opcode causes all write
-** operations since the previous successful call to
-** [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] to be rolled back.
-** ^This file control takes the file descriptor out of batch write mode
-** so that all subsequent write operations are independent.
-** ^SQLite will never invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE without
-** a prior successful call to [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE].
-**
-** <li>[[SQLITE_FCNTL_LOCK_TIMEOUT]]
-** The [SQLITE_FCNTL_LOCK_TIMEOUT] opcode is used to configure a VFS
-** to block for up to M milliseconds before failing when attempting to
-** obtain a file lock using the xLock or xShmLock methods of the VFS.
-** The parameter is a pointer to a 32-bit signed integer that contains
-** the value that M is to be set to. Before returning, the 32-bit signed
-** integer is overwritten with the previous value of M.
-**
-** <li>[[SQLITE_FCNTL_DATA_VERSION]]
-** The [SQLITE_FCNTL_DATA_VERSION] opcode is used to detect changes to
-** a database file.  The argument is a pointer to a 32-bit unsigned integer.
-** The "data version" for the pager is written into the pointer.  The
-** "data version" changes whenever any change occurs to the corresponding
-** database file, either through SQL statements on the same database
-** connection or through transactions committed by separate database
-** connections possibly in other processes. The [sqlite3_total_changes()]
-** interface can be used to find if any database on the connection has changed,
-** but that interface responds to changes on TEMP as well as MAIN and does
-** not provide a mechanism to detect changes to MAIN only.  Also, the
-** [sqlite3_total_changes()] interface responds to internal changes only and
-** omits changes made by other database connections.  The
-** [PRAGMA data_version] command provides a mechanism to detect changes to
-** a single attached database that occur due to other database connections,
-** but omits changes implemented by the database connection on which it is
-** called.  This file control is the only mechanism to detect changes that
-** happen either internally or externally and that are associated with
-** a particular attached database.
-**
-** <li>[[SQLITE_FCNTL_CKPT_START]]
-** The [SQLITE_FCNTL_CKPT_START] opcode is invoked from within a checkpoint
-** in wal mode before the client starts to copy pages from the wal
-** file to the database file.
-**
-** <li>[[SQLITE_FCNTL_CKPT_DONE]]
-** The [SQLITE_FCNTL_CKPT_DONE] opcode is invoked from within a checkpoint
-** in wal mode after the client has finished copying pages from the wal
-** file to the database file, but before the *-shm file is updated to
-** record the fact that the pages have been checkpointed.
-**
-** <li>[[SQLITE_FCNTL_EXTERNAL_READER]]
-** The EXPERIMENTAL [SQLITE_FCNTL_EXTERNAL_READER] opcode is used to detect
-** whether or not there is a database client in another process with a wal-mode
-** transaction open on the database or not. It is only available on unix.The
-** (void*) argument passed with this file-control should be a pointer to a
-** value of type (int). The integer value is set to 1 if the database is a wal
-** mode database and there exists at least one client in another process that
-** currently has an SQL transaction open on the database. It is set to 0 if
-** the database is not a wal-mode db, or if there is no such connection in any
-** other process. This opcode cannot be used to detect transactions opened
-** by clients within the current process, only within other processes.
-**
-** <li>[[SQLITE_FCNTL_CKSM_FILE]]
-** The [SQLITE_FCNTL_CKSM_FILE] opcode is for use internally by the
-** [checksum VFS shim] only.
-**
-** <li>[[SQLITE_FCNTL_RESET_CACHE]]
-** If there is currently no transaction open on the database, and the
-** database is not a temp db, then the [SQLITE_FCNTL_RESET_CACHE] file-control
-** purges the contents of the in-memory page cache. If there is an open
-** transaction, or if the db is a temp-db, this opcode is a no-op, not an error.

-** the end.  Each time such an extension occurs, the iVersion field
-** is incremented.  The iVersion value started out as 1 in
-** SQLite [version 3.5.0] on [dateof:3.5.0], then increased to 2
-** with SQLite [version 3.7.0] on [dateof:3.7.0], and then increased
-** to 3 with SQLite [version 3.7.6] on [dateof:3.7.6].  Additional fields
-** may be appended to the sqlite3_vfs object and the iVersion value
-** may increase again in future versions of SQLite.
-** Note that due to an oversight, the structure
-** of the sqlite3_vfs object changed in the transition from
-** SQLite [version 3.5.9] to [version 3.6.0] on [dateof:3.6.0]
-** and yet the iVersion field was not increased.
-**
-** The szOsFile field is the size of the subclassed [sqlite3_file]
-** structure used by this VFS.  mxPathname is the maximum length of
-** a pathname in this VFS.
-**
-** Registered sqlite3_vfs objects are kept on a linked list formed by
-** the pNext pointer.  The [sqlite3_vfs_register()]
-** and [sqlite3_vfs_unregister()] interfaces manage this list
-** in a thread-safe way.  The [sqlite3_vfs_find()] interface
-** searches the list.  Neither the application code nor the VFS
-** implementation should use the pNext pointer.
-**
-** The pNext field is the only field in the sqlite3_vfs
-** structure that SQLite will ever modify.  SQLite will only access
-** or modify this field while holding a particular static mutex.
-** The application should never modify anything within the sqlite3_vfs
-** object once the object has been registered.
-**
-** The zName field holds the name of the VFS module.  The name must
-** be unique across all VFS modules.
-**
-** [[sqlite3_vfs.xOpen]]
-** ^SQLite guarantees that the zFilename parameter to xOpen
-** is either a NULL pointer or string obtained
-** from xFullPathname() with an optional suffix added.
-** ^If a suffix is added to the zFilename parameter, it will
-** consist of a single "-" character followed by no more than
-** 11 alphanumeric and/or "-" characters.
-** ^SQLite further guarantees that
-** the string will be valid and unchanged until xClose() is
-** called. Because of the previous sentence,
-** the [sqlite3_file] can safely store a pointer to the
-** filename if it needs to remember the filename for some reason.
-** If the zFilename parameter to xOpen is a NULL pointer then xOpen
-** must invent its own temporary name for the file.  ^Whenever the
-** xFilename parameter is NULL it will also be the case that the
-** flags parameter will include [SQLITE_OPEN_DELETEONCLOSE].
-**
-** The flags argument to xOpen() includes all bits set in
-** the flags argument to [sqlite3_open_v2()].  Or if [sqlite3_open()]
-** or [sqlite3_open16()] is used, then flags includes at least
-** [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE].
-** If xOpen() opens a file read-only then it sets *pOutFlags to
-** include [SQLITE_OPEN_READONLY].  Other bits in *pOutFlags may be set.
-**
-** ^(SQLite will also add one of the following flags to the xOpen()
-** call, depending on the object being opened:
-**
-** <ul>
-** <li>  [SQLITE_OPEN_MAIN_DB]
-** <li>  [SQLITE_OPEN_MAIN_JOURNAL]
-** <li>  [SQLITE_OPEN_TEMP_DB]
-** <li>  [SQLITE_OPEN_TEMP_JOURNAL]
-** <li>  [SQLITE_OPEN_TRANSIENT_DB]
-** <li>  [SQLITE_OPEN_SUBJOURNAL]
-** <li>  [SQLITE_OPEN_SUPER_JOURNAL]
-** <li>  [SQLITE_OPEN_WAL]
-** </ul>)^
-**
-** The file I/O implementation can use the object type flags to
-** change the way it deals with files.  For example, an application
-** that does not care about crash recovery or rollback might make
-** the open of a journal file a no-op.  Writes to this journal would
-** also be no-ops, and any attempt to read the journal would return
-** SQLITE_IOERR.  Or the implementation might recognize that a database
-** file will be doing page-aligned sector reads and writes in a random
-** order and set up its I/O subsystem accordingly.
-**
-** SQLite might also add one of the following flags to the xOpen method:
-**
-** <ul>
-** <li> [SQLITE_OPEN_DELETEONCLOSE]
-** <li> [SQLITE_OPEN_EXCLUSIVE]
-** </ul>
-**
-** The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be
-** deleted when it is closed.  ^The [SQLITE_OPEN_DELETEONCLOSE]
-** will be set for TEMP databases and their journals, transient
-** databases, and subjournals.
-**
-** ^The [SQLITE_OPEN_EXCLUSIVE] flag is always used in conjunction
-** with the [SQLITE_OPEN_CREATE] flag, which are both directly
-** analogous to the O_EXCL and O_CREAT flags of the POSIX open()
-** API.  The SQLITE_OPEN_EXCLUSIVE flag, when paired with the
-** SQLITE_OPEN_CREATE, is used to indicate that file should always
-** be created, and that it is an error if it already exists.
-** It is <i>not</i> used to indicate the file should be opened
-** for exclusive access.
-**
-** ^At least szOsFile bytes of memory are allocated by SQLite
-** to hold the [sqlite3_file] structure passed as the third
-** argument to xOpen.  The xOpen method does not have to
-** allocate the structure; it should just fill it in.  Note that
-** the xOpen method must set the sqlite3_file.pMethods to either
-** a valid [sqlite3_io_methods] object or to NULL.  xOpen must do
-** this even if the open fails.  SQLite expects that the sqlite3_file.pMethods
-** element will be valid after xOpen returns regardless of the success
-** or failure of the xOpen call.
-**
-** [[sqlite3_vfs.xAccess]]
-** ^The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS]
-** to test for the existence of a file, or [SQLITE_ACCESS_READWRITE] to
-** test whether a file is readable and writable, or [SQLITE_ACCESS_READ]
-** to test whether a file is at least readable.  The SQLITE_ACCESS_READ
-** flag is never actually used and is not implemented in the built-in
-** VFSes of SQLite.  The file is named by the second argument and can be a
-** directory. The xAccess method returns [SQLITE_OK] on success or some
-** non-zero error code if there is an I/O error or if the name of
-** the file given in the second argument is illegal.  If SQLITE_OK
-** is returned, then non-zero or zero is written into *pResOut to indicate
-** whether or not the file is accessible.
-**
-** ^SQLite will always allocate at least mxPathname+1 bytes for the
-** output buffer xFullPathname.  The exact size of the output buffer
-** is also passed as a parameter to both  methods. If the output buffer
-** is not large enough, [SQLITE_CANTOPEN] should be returned. Since this is
-** handled as a fatal error by SQLite, vfs implementations should endeavor
-** to prevent this by setting mxPathname to a sufficiently large value.
-**
-** The xRandomness(), xSleep(), xCurrentTime(), and xCurrentTimeInt64()
-** interfaces are not strictly a part of the filesystem, but they are
-** included in the VFS structure for completeness.
-** The xRandomness() function attempts to return nBytes bytes
-** of good-quality randomness into zOut.  The return value is
-** the actual number of bytes of randomness obtained.
-** The xSleep() method causes the calling thread to sleep for at
-** least the number of microseconds given.  ^The xCurrentTime()
-** method returns a Julian Day Number for the current date and time as
-** a floating point value.
-** ^The xCurrentTimeInt64() method returns, as an integer, the Julian
-** Day Number multiplied by 86400000 (the number of milliseconds in
-** a 24-hour day).
-** ^SQLite will use the xCurrentTimeInt64() method to get the current
-** date and time if that method is available (if iVersion is 2 or
-** greater and the function pointer is not NULL) and will fall back
-** to xCurrentTime() if xCurrentTimeInt64() is unavailable.
-**
-** ^The xSetSystemCall(), xGetSystemCall(), and xNestSystemCall() interfaces
-** are not used by the SQLite core.  These optional interfaces are provided
-** by some VFSes to facilitate testing of the VFS code. By overriding
-** system calls with functions under its control, a test program can
-** simulate faults and error conditions that would otherwise be difficult
-** or impossible to induce.  The set of system calls that can be overridden
-** varies from one VFS to another, and from one version of the same VFS to the
-** next.  Applications that use these interfaces must be prepared for any
-** or all of these interfaces to be NULL or for their behavior to change
-** from one release to the next.  Applications must not attempt to access
-** any of these methods if the iVersion of the VFS is less than 3.

-** These routines are designed to aid in process initialization and

-** SQLite normally do not need to invoke either of these routines.
-**
-** A call to sqlite3_initialize() is an "effective" call if it is
-** the first time sqlite3_initialize() is invoked during the lifetime of
-** the process, or if it is the first time sqlite3_initialize() is invoked
-** following a call to sqlite3_shutdown().  ^(Only an effective call
-** of sqlite3_initialize() does any initialization.  All other calls
-** are harmless no-ops.)^
-**

-** call to sqlite3_shutdown() since the last sqlite3_initialize().  ^(Only

-** All other valid calls to sqlite3_shutdown() are harmless no-ops.)^
-**
-** The sqlite3_initialize() interface is threadsafe, but sqlite3_shutdown()
-** is not.  The sqlite3_shutdown() interface must only be called from a
-** single thread.  All open [database connections] must be closed and all
-** other SQLite resources must be deallocated prior to invoking
-** sqlite3_shutdown().
-**
-** Among other things, ^sqlite3_initialize() will invoke
-** sqlite3_os_init().  Similarly, ^sqlite3_shutdown()
-** will invoke sqlite3_os_end().
-**
-** ^The sqlite3_initialize() routine returns [SQLITE_OK] on success.
-** ^If for some reason, sqlite3_initialize() is unable to initialize
-** the library (perhaps it is unable to allocate a needed resource such
-** as a mutex) it returns an [error code] other than [SQLITE_OK].
-**
-** ^The sqlite3_initialize() routine is called internally by many other
-** SQLite interfaces so that an application usually does not need to
-** invoke sqlite3_initialize() directly.  For example, [sqlite3_open()]
-** calls sqlite3_initialize() so the SQLite library will be automatically

-** are omitted and the application must call sqlite3_initialize() directly
-** prior to using any other SQLite interface.  For maximum portability,
-** it is recommended that applications always invoke sqlite3_initialize()
-** directly prior to using any other SQLite interface.  Future releases
-** of SQLite may require this.  In other words, the behavior exhibited
-** when SQLite is compiled with [SQLITE_OMIT_AUTOINIT] might become the
-** default behavior in some future release of SQLite.
-**
-** The sqlite3_os_init() routine does operating-system specific
-** initialization of the SQLite library.  The sqlite3_os_end()
-** routine undoes the effect of sqlite3_os_init().  Typical tasks

-** and that this object is only useful to a tiny minority of applications
-** with specialized memory allocation requirements.  This object is

-** memory allocator that simulates memory out-of-memory conditions in
-** order to verify that SQLite recovers gracefully from such
-** conditions.
-**
-** The xMalloc, xRealloc, and xFree methods must work like the
-** malloc(), realloc() and free() functions from the standard C library.
-** ^SQLite guarantees that the second argument to

-**
-** xSize should return the allocated size of a memory allocation
-** previously obtained from xMalloc or xRealloc.  The allocated size
-** is always at least as big as the requested size but may be larger.

-** The xRoundup method returns what would be the allocated size of

-** allocators round up memory allocations at least to the next multiple
-** of 8.  Some allocators round up to a larger multiple or to a power of 2.
-** Every memory allocation request coming in through [sqlite3_malloc()]
-** or [sqlite3_realloc()] first calls xRoundup.  If xRoundup returns 0,
-** that causes the corresponding memory allocation to fail.

-** is another alias for the rowid.
-**
-** ^The sqlite3_last_insert_rowid(D) interface usually returns the [rowid] of
-** the most recent successful [INSERT] into a rowid table or [virtual table]
-** on database connection D. ^Inserts into [WITHOUT ROWID] tables are not
-** recorded. ^If no successful [INSERT]s into rowid tables have ever occurred
-** on the database connection D, then sqlite3_last_insert_rowid(D) returns
-** zero.
-**
-** As well as being set automatically as rows are inserted into database
-** tables, the value returned by this function may be set explicitly by
-** [sqlite3_set_last_insert_rowid()]
-**
-** Some virtual table implementations may INSERT rows into rowid tables as
-** part of committing a transaction (e.g. to flush data accumulated in memory
-** to disk). In this case subsequent calls to this function return the rowid
-** associated with these internal INSERT operations, which leads to

-** rowid value using [sqlite3_set_last_insert_rowid()] before returning
-** control to the user.
-**
-** ^(If an [INSERT] occurs within a trigger then this routine will
-** return the [rowid] of the inserted row as long as the trigger is

-** CAPI3REF: Register A Callback To Handle SQLITE_BUSY Errors
-** KEYWORDS: {busy-handler callback} {busy handler}
-** METHOD: sqlite3
-**
-** ^The sqlite3_busy_handler(D,X,P) routine sets a callback function X
-** that might be invoked with argument P whenever
-** an attempt is made to access a database table associated with
-** [database connection] D when another thread
-** or process has the table locked.
-** The sqlite3_busy_handler() interface is used to implement
-** [sqlite3_busy_timeout()] and [PRAGMA busy_timeout].
-**
-** ^If the busy callback is NULL, then [SQLITE_BUSY]
-** is returned immediately upon encountering the lock.  ^If the busy callback
-** is not NULL, then the callback might be invoked with two arguments.
-**
-** ^The first argument to the busy handler is a copy of the void* pointer which
-** is the third argument to sqlite3_busy_handler().  ^The second argument to
-** the busy handler callback is the number of times that the busy handler has
-** been invoked previously for the same locking event.  ^If the
-** busy callback returns 0, then no additional attempts are made to
-** access the database and [SQLITE_BUSY] is returned
-** to the application.
-** ^If the callback returns non-zero, then another attempt
-** is made to access the database and the cycle repeats.
-**
-** The presence of a busy handler does not guarantee that it will be invoked
-** when there is lock contention. ^If SQLite determines that invoking the busy
-** handler could result in a deadlock, it will go ahead and return [SQLITE_BUSY]
-** to the application instead of invoking the
-** busy handler.
-** Consider a scenario where one process is holding a read lock that
-** it is trying to promote to a reserved lock and
-** a second process is holding a reserved lock that it is trying
-** to promote to an exclusive lock.  The first process cannot proceed
-** because it is blocked by the second and the second process cannot
-** proceed because it is blocked by the first.  If both processes
-** invoke the busy handlers, neither will make any progress.  Therefore,
-** SQLite returns [SQLITE_BUSY] for the first process, hoping that this
-** will induce the first process to release its read lock and allow
-** the second process to proceed.
-**
-** ^The default busy callback is NULL.
-**
-** ^(There can only be a single busy handler defined for each
-** [database connection].  Setting a new busy handler clears any
-** previously set handler.)^  ^Note that calling [sqlite3_busy_timeout()]
-** or evaluating [PRAGMA busy_timeout=N] will change the
-** busy handler and thus clear any previously set busy handler.
-**
-** The busy callback should not take any actions which modify the
-** database connection that invoked the busy handler.  In other words,
-** the busy handler is not reentrant.  Any such actions
-** result in undefined behavior.
-**
-** A busy handler must not close the database connection
-** or [prepared statement] that invoked the busy handler.

-** CAPI3REF: Convenience Routines For Running Queries
-** METHOD: sqlite3
-**
-** This is a legacy interface that is preserved for backwards compatibility.
-** Use of this interface is not recommended.
-**
-** Definition: A <b>result table</b> is memory data structure created by the
-** [sqlite3_get_table()] interface.  A result table records the
-** complete query results from one or more queries.
-**
-** The table conceptually has a number of rows and columns.  But
-** these numbers are not part of the result table itself.  These
-** numbers are obtained separately.  Let N be the number of rows
-** and M be the number of columns.
-**
-** A result table is an array of pointers to zero-terminated UTF-8 strings.
-** There are (N+1)*M elements in the array.  The first M pointers point
-** to zero-terminated strings that  contain the names of the columns.
-** The remaining entries all point to query results.  NULL values result
-** in NULL pointers.  All other values are in their UTF-8 zero-terminated
-** string representation as returned by [sqlite3_column_text()].
-**
-** A result table might consist of one or more memory allocations.
-** It is not safe to pass a result table directly to [sqlite3_free()].
-** A result table should be deallocated using [sqlite3_free_table()].
-**
-** ^(As an example of the result table format, suppose a query result
-** is as follows:
-**
-** <blockquote><pre>
-**        Name        | Age
-**        -----------------------
-**        Alice       | 43
-**        Bob         | 28
-**        Cindy       | 21
-** </pre></blockquote>
-**
-** There are two columns (M==2) and three rows (N==3).  Thus the
-** result table has 8 entries.  Suppose the result table is stored
-** in an array named azResult.  Then azResult holds this content:
-**
-** <blockquote><pre>
-**        azResult&#91;0] = "Name";
-**        azResult&#91;1] = "Age";
-**        azResult&#91;2] = "Alice";
-**        azResult&#91;3] = "43";
-**        azResult&#91;4] = "Bob";
-**        azResult&#91;5] = "28";
-**        azResult&#91;6] = "Cindy";
-**        azResult&#91;7] = "21";
-** </pre></blockquote>)^
-**
-** ^The sqlite3_get_table() function evaluates one or more
-** semicolon-separated SQL statements in the zero-terminated UTF-8
-** string of its 2nd parameter and returns a result table to the
-** pointer given in its 3rd parameter.
-**
-** After the application has finished with the result from sqlite3_get_table(),
-** it must pass the result table pointer to sqlite3_free_table() in order to
-** release the memory that was malloced.  Because of the way the
-** [sqlite3_malloc()] happens within sqlite3_get_table(), the calling
-** function must not try to call [sqlite3_free()] directly.  Only
-** [sqlite3_free_table()] is able to release the memory properly and safely.
-**
-** The sqlite3_get_table() interface is implemented as a wrapper around
-** [sqlite3_exec()].  The sqlite3_get_table() routine does not have access
-** to any internal data structures of SQLite.  It uses only the public
-** interface defined here.  As a consequence, errors that occur in the
-** wrapper layer outside of the internal [sqlite3_exec()] call are not
-** reflected in subsequent calls to [sqlite3_errcode()] or
-** [sqlite3_errmsg()].

-** CAPI3REF: Memory Allocation Subsystem

-** does not include operating-system specific [VFS] implementation.  The
-** Windows VFS uses native malloc() and free() for some operations.
-**
-** ^The sqlite3_malloc() routine returns a pointer to a block

-** ^If sqlite3_malloc() is unable to obtain sufficient free
-** memory, it returns a NULL pointer.  ^If the parameter N to
-** sqlite3_malloc() is zero or negative then sqlite3_malloc() returns

-**
-** ^The sqlite3_malloc64(N) routine works just like
-** sqlite3_malloc(N) except that N is an unsigned 64-bit integer instead
-** of a signed 32-bit integer.
-**
-** ^Calling sqlite3_free() with a pointer previously returned
-** by sqlite3_malloc() or sqlite3_realloc() releases that memory so
-** that it might be reused.  ^The sqlite3_free() routine is
-** a no-op if is called with a NULL pointer.  Passing a NULL pointer
-** to sqlite3_free() is harmless.  After being freed, memory
-** should neither be read nor written.  Even reading previously freed

-** Memory corruption, a segmentation fault, or other severe error
-** might result if sqlite3_free() is called with a non-NULL pointer that
-** was not obtained from sqlite3_malloc() or sqlite3_realloc().
-**
-** ^The sqlite3_realloc(X,N) interface attempts to resize a
-** prior memory allocation X to be at least N bytes.
-** ^If the X parameter to sqlite3_realloc(X,N)
-** is a NULL pointer then its behavior is identical to calling
-** sqlite3_malloc(N).
-** ^If the N parameter to sqlite3_realloc(X,N) is zero or
-** negative then the behavior is exactly the same as calling
-** sqlite3_free(X).
-** ^sqlite3_realloc(X,N) returns a pointer to a memory allocation
-** of at least N bytes in size or NULL if insufficient memory is available.
-** ^If M is the size of the prior allocation, then min(N,M) bytes
-** of the prior allocation are copied into the beginning of buffer returned
-** by sqlite3_realloc(X,N) and the prior allocation is freed.
-** ^If sqlite3_realloc(X,N) returns NULL and N is positive, then the
-** prior allocation is not freed.
-**
-** ^The sqlite3_realloc64(X,N) interfaces works the same as
-** sqlite3_realloc(X,N) except that N is a 64-bit unsigned integer instead
-** of a 32-bit signed integer.
-**
-** ^If X is a memory allocation previously obtained from sqlite3_malloc(),
-** sqlite3_malloc64(), sqlite3_realloc(), or sqlite3_realloc64(), then
-** sqlite3_msize(X) returns the size of that memory allocation in bytes.
-** ^The value returned by sqlite3_msize(X) might be larger than the number
-** of bytes requested when X was allocated.  ^If X is a NULL pointer then
-** sqlite3_msize(X) returns zero.  If X points to something that is not

-** METHOD: sqlite3
-** KEYWORDS: {authorizer callback}
-**
-** ^This routine registers an authorizer callback with a particular

-** ^The authorizer callback is invoked as SQL statements are being compiled
-** by [sqlite3_prepare()] or its variants [sqlite3_prepare_v2()],
-** [sqlite3_prepare_v3()], [sqlite3_prepare16()], [sqlite3_prepare16_v2()],
-** and [sqlite3_prepare16_v3()].  ^At various
-** points during the compilation process, as logic is being created
-** to perform various actions, the authorizer callback is invoked to
-** see if those actions are allowed.  ^The authorizer callback should
-** return [SQLITE_OK] to allow the action, [SQLITE_IGNORE] to disallow the
-** specific action but allow the SQL statement to continue to be
-** compiled, or [SQLITE_DENY] to cause the entire SQL statement to be
-** rejected with an error.  ^If the authorizer callback returns
-** any value other than [SQLITE_IGNORE], [SQLITE_OK], or [SQLITE_DENY]
-** then the [sqlite3_prepare_v2()] or equivalent call that triggered
-** the authorizer will fail with an error message.
-**
-** When the callback returns [SQLITE_OK], that means the operation
-** requested is ok.  ^When the callback returns [SQLITE_DENY], the
-** [sqlite3_prepare_v2()] or equivalent call that triggered the
-** authorizer will fail with an error message explaining that
-** access is denied.
-**
-** ^The first parameter to the authorizer callback is a copy of the third
-** parameter to the sqlite3_set_authorizer() interface. ^The second parameter
-** to the callback is an integer [SQLITE_COPY | action code] that specifies
-** the particular action to be authorized. ^The third through sixth parameters
-** to the callback are either NULL pointers or zero-terminated strings
-** that contain additional details about the action to be authorized.
-** Applications must always be prepared to encounter a NULL pointer in any
-** of the third through the sixth parameters of the authorization callback.
-**
-** ^If the action code is [SQLITE_READ]
-** and the callback returns [SQLITE_IGNORE] then the
-** [prepared statement] statement is constructed to substitute
-** a NULL value in place of the table column that would have
-** been read if [SQLITE_OK] had been returned.  The [SQLITE_IGNORE]
-** return can be used to deny an untrusted user access to individual
-** columns of a table.
-** ^When a table is referenced by a [SELECT] but no column values are
-** extracted from that table (for example in a query like
-** "SELECT count(*) FROM tab") then the [SQLITE_READ] authorizer callback
-** is invoked once for that table with a column name that is an empty string.
-** ^If the action code is [SQLITE_DELETE] and the callback returns
-** [SQLITE_IGNORE] then the [DELETE] operation proceeds but the
-** [truncate optimization] is disabled and all rows are deleted individually.
-**
-** An authorizer is used when [sqlite3_prepare | preparing]
-** SQL statements from an untrusted source, to ensure that the SQL statements
-** do not try to access data they are not allowed to see, or that they do not
-** try to execute malicious statements that damage the database.  For
-** example, an application may allow a user to enter arbitrary
-** SQL queries for evaluation by a database.  But the application does
-** not want the user to be able to make arbitrary changes to the
-** database.  An authorizer could then be put in place while the
-** user-entered SQL is being [sqlite3_prepare | prepared] that
-** disallows everything except [SELECT] statements.
-**
-** Applications that need to process SQL from untrusted sources
-** might also consider lowering resource limits using [sqlite3_limit()]
-** and limiting database size using the [max_page_count] [PRAGMA]
-** in addition to using an authorizer.
-**
-** ^(Only a single authorizer can be in place on a database connection
-** at a time.  Each call to sqlite3_set_authorizer overrides the

-**
-** ^Note that the authorizer callback is invoked only during

-**
-** [[URI filenames in sqlite3_open()]] <h3>URI Filenames</h3>
-**
-** ^If [URI filename] interpretation is enabled, and the filename argument
-** begins with "file:", then the filename is interpreted as a URI. ^URI
-** filename interpretation is enabled if the [SQLITE_OPEN_URI] flag is
-** set in the third argument to sqlite3_open_v2(), or if it has
-** been enabled globally using the [SQLITE_CONFIG_URI] option with the
-** [sqlite3_config()] method or by the [SQLITE_USE_URI] compile-time option.
-** URI filename interpretation is turned off
-** by default, but future releases of SQLite might enable URI filename
-** interpretation by default.  See "[URI filenames]" for additional
-** information.
-**
-** URI filenames are parsed according to RFC 3986. ^If the URI contains an
-** authority, then it must be either an empty string or the string
-** "localhost". ^If the authority is not an empty string or "localhost", an
-** error is returned to the caller. ^The fragment component of a URI, if
-** present, is ignored.
-**
-** ^SQLite uses the path component of the URI as the name of the disk file
-** which contains the database. ^If the path begins with a '/' character,
-** then it is interpreted as an absolute path. ^If the path does not begin
-** with a '/' (meaning that the authority section is omitted from the URI)
-** then the path is interpreted as a relative path.
-** ^(On windows, the first component of an absolute path
-** is a drive specification (e.g. "C:").)^
-**
-** [[core URI query parameters]]
-** The query component of a URI may contain parameters that are interpreted
-** either by SQLite itself, or by a [VFS | custom VFS implementation].
-** SQLite and its built-in [VFSes] interpret the
-** following query parameters:
-**
-** <ul>
-**   <li> <b>vfs</b>: ^The "vfs" parameter may be used to specify the name of
-**     a VFS object that provides the operating system interface that should
-**     be used to access the database file on disk. ^If this option is set to
-**     an empty string the default VFS object is used. ^Specifying an unknown
-**     VFS is an error. ^If sqlite3_open_v2() is used and the vfs option is
-**     present, then the VFS specified by the option takes precedence over
-**     the value passed as the fourth parameter to sqlite3_open_v2().
-**
-**   <li> <b>mode</b>: ^(The mode parameter may be set to either "ro", "rw",
-**     "rwc", or "memory". Attempting to set it to any other value is
-**     an error)^.
-**     ^If "ro" is specified, then the database is opened for read-only
-**     access, just as if the [SQLITE_OPEN_READONLY] flag had been set in the
-**     third argument to sqlite3_open_v2(). ^If the mode option is set to
-**     "rw", then the database is opened for read-write (but not create)
-**     access, as if SQLITE_OPEN_READWRITE (but not SQLITE_OPEN_CREATE) had
-**     been set. ^Value "rwc" is equivalent to setting both
-**     SQLITE_OPEN_READWRITE and SQLITE_OPEN_CREATE.  ^If the mode option is
-**     set to "memory" then a pure [in-memory database] that never reads
-**     or writes from disk is used. ^It is an error to specify a value for
-**     the mode parameter that is less restrictive than that specified by
-**     the flags passed in the third parameter to sqlite3_open_v2().
-**
-**   <li> <b>cache</b>: ^The cache parameter may be set to either "shared" or
-**     "private". ^Setting it to "shared" is equivalent to setting the
-**     SQLITE_OPEN_SHAREDCACHE bit in the flags argument passed to
-**     sqlite3_open_v2(). ^Setting the cache parameter to "private" is
-**     equivalent to setting the SQLITE_OPEN_PRIVATECACHE bit.
-**     ^If sqlite3_open_v2() is used and the "cache" parameter is present in
-**     a URI filename, its value overrides any behavior requested by setting
-**     SQLITE_OPEN_PRIVATECACHE or SQLITE_OPEN_SHAREDCACHE flag.
-**
-**  <li> <b>psow</b>: ^The psow parameter indicates whether or not the
-**     [powersafe overwrite] property does or does not apply to the
-**     storage media on which the database file resides.
-**
-**  <li> <b>nolock</b>: ^The nolock parameter is a boolean query parameter
-**     which if set disables file locking in rollback journal modes.  This
-**     is useful for accessing a database on a filesystem that does not
-**     support locking.  Caution:  Database corruption might result if two
-**     or more processes write to the same database and any one of those
-**     processes uses nolock=1.
-**
-**  <li> <b>immutable</b>: ^The immutable parameter is a boolean query
-**     parameter that indicates that the database file is stored on
-**     read-only media.  ^When immutable is set, SQLite assumes that the
-**     database file cannot be changed, even by a process with higher
-**     privilege, and so the database is opened read-only and all locking
-**     and change detection is disabled.  Caution: Setting the immutable
-**     property on a database file that does in fact change can result
-**     in incorrect query results and/or [SQLITE_CORRUPT] errors.
-**     See also: [SQLITE_IOCAP_IMMUTABLE].
-**
-** </ul>
-**
-** ^Specifying an unknown parameter in the query component of a URI is not an
-** error.  Future versions of SQLite might understand additional query
-** parameters.  See "[query parameters with special meaning to SQLite]" for
-** additional information.

-** and if P is the name of the query parameter, then

-** query parameter on F.  If P is a query parameter of F and it
-** has no explicit value, then sqlite3_uri_parameter(F,P) returns
-** a pointer to an empty string.
-**
-** The sqlite3_uri_boolean(F,P,B) routine assumes that P is a boolean
-** parameter and returns true (1) or false (0) according to the value
-** of P.  The sqlite3_uri_boolean(F,P,B) routine returns true (1) if the
-** value of query parameter P is one of "yes", "true", or "on" in any
-** case or if the value begins with a non-zero number.  The
-** sqlite3_uri_boolean(F,P,B) routines returns false (0) if the value of
-** query parameter P is one of "no", "false", or "off" in any case or
-** if the value begins with a numeric zero.  If P is not a query
-** parameter on F or if the value of P does not match any of the
-** above, then sqlite3_uri_boolean(F,P,B) returns (B!=0).
-**
-** The sqlite3_uri_int64(F,P,D) routine converts the value of P into a
-** 64-bit signed integer and returns that integer, or D if P does not
-** exist.  If the value of P is something other than an integer, then
-** zero is returned.
-**
-** The sqlite3_uri_key(F,N) returns a pointer to the name (not
-** the value) of the N-th query parameter for filename F, or a NULL
-** pointer if N is less than zero or greater than the number of query
-** parameters minus 1.  The N value is zero-based so N should be 0 to obtain
-** the name of the first query parameter, 1 for the second parameter, and
-** so forth.
-**
-** If F is a NULL pointer, then sqlite3_uri_parameter(F,P) returns NULL and
-** sqlite3_uri_boolean(F,P,B) returns B.  If F is not a NULL pointer and

-** CAPI3REF: Compiling An SQL Statement
-** KEYWORDS: {SQL statement compiler}
-** METHOD: sqlite3
-** CONSTRUCTOR: sqlite3_stmt
-**
-** To execute an SQL statement, it must first be compiled into a byte-code
-** program using one of these routines.  Or, in other words, these routines
-** are constructors for the [prepared statement] object.
-**
-** The preferred routine to use is [sqlite3_prepare_v2()].  The
-** [sqlite3_prepare()] interface is legacy and should be avoided.
-** [sqlite3_prepare_v3()] has an extra "prepFlags" option that is used
-** for special purposes.
-**
-** The use of the UTF-8 interfaces is preferred, as SQLite currently
-** does all parsing using UTF-8.  The UTF-16 interfaces are provided
-** as a convenience.  The UTF-16 interfaces work by converting the
-** input text into UTF-8, then invoking the corresponding UTF-8 interface.
-**
-** The first argument, "db", is a [database connection] obtained from a
-** prior successful call to [sqlite3_open()], [sqlite3_open_v2()] or
-** [sqlite3_open16()].  The database connection must not have been closed.
-**
-** The second argument, "zSql", is the statement to be compiled, encoded
-** as either UTF-8 or UTF-16.  The sqlite3_prepare(), sqlite3_prepare_v2(),
-** and sqlite3_prepare_v3()
-** interfaces use UTF-8, and sqlite3_prepare16(), sqlite3_prepare16_v2(),
-** and sqlite3_prepare16_v3() use UTF-16.
-**
-** ^If the nByte argument is negative, then zSql is read up to the
-** first zero terminator. ^If nByte is positive, then it is the
-** number of bytes read from zSql.  ^If nByte is zero, then no prepared
-** statement is generated.
-** If the caller knows that the supplied string is nul-terminated, then
-** there is a small performance advantage to passing an nByte parameter that
-** is the number of bytes in the input string <i>including</i>
-** the nul-terminator.
-**
-** ^If pzTail is not NULL then *pzTail is made to point to the first byte
-** past the end of the first SQL statement in zSql.  These routines only
-** compile the first statement in zSql, so *pzTail is left pointing to
-** what remains uncompiled.
-**
-** ^*ppStmt is left pointing to a compiled [prepared statement] that can be
-** executed using [sqlite3_step()].  ^If there is an error, *ppStmt is set
-** to NULL.  ^If the input text contains no SQL (if the input is an empty
-** string or a comment) then *ppStmt is set to NULL.
-** The calling procedure is responsible for deleting the compiled
-** SQL statement using [sqlite3_finalize()] after it has finished with it.
-** ppStmt may not be NULL.
-**
-** ^On success, the sqlite3_prepare() family of routines return [SQLITE_OK];
-** otherwise an [error code] is returned.
-**
-** The sqlite3_prepare_v2(), sqlite3_prepare_v3(), sqlite3_prepare16_v2(),
-** and sqlite3_prepare16_v3() interfaces are recommended for all new programs.
-** The older interfaces (sqlite3_prepare() and sqlite3_prepare16())
-** are retained for backwards compatibility, but their use is discouraged.
-** ^In the "vX" interfaces, the prepared statement
-** that is returned (the [sqlite3_stmt] object) contains a copy of the
-** original SQL text. This causes the [sqlite3_step()] interface to
-** behave differently in three ways:
-**
-** <ol>
-** <li>
-** ^If the database schema changes, instead of returning [SQLITE_SCHEMA] as it
-** always used to do, [sqlite3_step()] will automatically recompile the SQL
-** statement and try to run it again. As many as [SQLITE_MAX_SCHEMA_RETRY]
-** retries will occur before sqlite3_step() gives up and returns an error.
-** </li>
-**
-** <li>
-** ^When an error occurs, [sqlite3_step()] will return one of the detailed
-** [error codes] or [extended error codes].  ^The legacy behavior was that
-** [sqlite3_step()] would only return a generic [SQLITE_ERROR] result code
-** and the application would have to make a second call to [sqlite3_reset()]
-** in order to find the underlying cause of the problem. With the "v2" prepare
-** interfaces, the underlying reason for the error is returned immediately.
-** </li>
-**
-** <li>
-** ^If the specific value bound to a [parameter | host parameter] in the
-** WHERE clause might influence the choice of query plan for a statement,
-** then the statement will be automatically recompiled, as if there had been
-** a schema change, on the first [sqlite3_step()] call following any change
-** to the [sqlite3_bind_text | bindings] of that [parameter].
-** ^The specific value of a WHERE-clause [parameter] might influence the
-** choice of query plan if the parameter is the left-hand side of a [LIKE]
-** or [GLOB] operator or if the parameter is compared to an indexed column
-** and the [SQLITE_ENABLE_STAT4] compile-time option is enabled.
-** </li>
-** </ol>
-**
-** <p>^sqlite3_prepare_v3() differs from sqlite3_prepare_v2() only in having
-** the extra prepFlags parameter, which is a bit array consisting of zero or
-** more of the [SQLITE_PREPARE_PERSISTENT|SQLITE_PREPARE_*] flags.  ^The
-** sqlite3_prepare_v2() interface works exactly the same as
-** sqlite3_prepare_v3() with a zero prepFlags parameter.

-** parameters (also called "host parameter names" or "SQL parameters")
-** can be set using the sqlite3_bind_*() routines defined here.
-**
-** ^The first argument to the sqlite3_bind_*() routines is always
-** a pointer to the [sqlite3_stmt] object returned from

-**
-** ^The second argument is the index of the SQL parameter to be set.

-** ^The NNN value must be between 1 and the [sqlite3_limit()]
-** parameter [SQLITE_LIMIT_VARIABLE_NUMBER] (default value: 32766).
-**
-** ^The third argument is the value to bind to the parameter.
-** ^If the third parameter to sqlite3_bind_text() or sqlite3_bind_text16()
-** or sqlite3_bind_blob() is a NULL pointer then the fourth parameter

-** either UTF8 if the sixth parameter is SQLITE_UTF8, or UTF16
-** otherwise.
-**
-** [[byte-order determination rules]] ^The byte-order of
-** UTF16 input text is determined by the byte-order mark (BOM, U+FEFF)

-** machine for sqlite3_bind_text16() or the byte order specified in

-** ^If UTF16 input text contains invalid unicode
-** characters, then SQLite might change those invalid characters
-** into the unicode replacement character: U+FFFD.

-** number of <u>bytes</u> in the value, not the number of characters.)^
-** ^If the fourth parameter to sqlite3_bind_text() or sqlite3_bind_text16()
-** is negative, then the length of the string is

-** If a non-negative fourth parameter is provided to sqlite3_bind_text()
-** or sqlite3_bind_text16() or sqlite3_bind_text64() then
-** that parameter must be the byte offset
-** where the NUL terminator would occur assuming the string were NUL
-** terminated.  If any NUL characters occurs at byte offsets less than
-** the value of the fourth parameter then the resulting string value will
-** contain embedded NULs.  The result of expressions involving strings
-** with embedded NULs is undefined.
-**
-** ^The fifth argument to the BLOB and string binding interfaces controls
-** or indicates the lifetime of the object referenced by the third parameter.
-** These three options exist:
-** ^ (1) A destructor to dispose of the BLOB or string after SQLite has finished
-** with it may be passed. ^It is called to dispose of the BLOB or string even
-** if the call to the bind API fails, except the destructor is not called if
-** the third parameter is a NULL pointer or the fourth parameter is negative.
-** ^ (2) The special constant, [SQLITE_STATIC], may be passed to indicate that
-** the application remains responsible for disposing of the object. ^In this
-** case, the object and the provided pointer to it must remain valid until
-** either the prepared statement is finalized or the same SQL parameter is
-** bound to something else, whichever occurs sooner.
-** ^ (3) The constant, [SQLITE_TRANSIENT], may be passed to indicate that the
-** object is to be copied prior to the return from sqlite3_bind_*(). ^The
-** object and pointer to it must remain valid until then. ^SQLite will then
-** manage the lifetime of its private copy.
-**
-** ^The sixth argument to sqlite3_bind_text64() must be one of
-** [SQLITE_UTF8], [SQLITE_UTF16], [SQLITE_UTF16BE], or [SQLITE_UTF16LE]
-** to specify the encoding of the text in the third parameter.  If
-** the sixth argument to sqlite3_bind_text64() is not one of the
-** allowed values shown above, or if the text encoding is different
-** from the encoding specified by the sixth parameter, then the behavior
-** is undefined.
-**
-** ^The sqlite3_bind_zeroblob() routine binds a BLOB of length N that

-** (just an integer to hold its size) while it is being processed.
-** Zeroblobs are intended to serve as placeholders for BLOBs whose
-** content is later written using
-** [sqlite3_blob_open | incremental BLOB I/O] routines.
-** ^A negative value for the zeroblob results in a zero-length BLOB.
-**
-** ^The sqlite3_bind_pointer(S,I,P,T,D) routine causes the I-th parameter in
-** [prepared statement] S to have an SQL value of NULL, but to also be
-** associated with the pointer P of type T.  ^D is either a NULL pointer or
-** a pointer to a destructor function for P. ^SQLite will invoke the

-** P.  The T parameter should be a static string, preferably a string
-** literal. The sqlite3_bind_pointer() routine is part of the
-** [pointer passing interface] added for SQLite 3.20.0.
-**
-** ^If any of the sqlite3_bind_*() routines are called with a NULL pointer
-** for the [prepared statement] or with a prepared statement for which
-** [sqlite3_step()] has been called more recently than [sqlite3_reset()],
-** then the call will return [SQLITE_MISUSE].  If any sqlite3_bind_()
-** routine is passed a [prepared statement] that has been finalized, the
-** result is undefined and probably harmful.
-**
-** ^Bindings are not cleared by the [sqlite3_reset()] routine.

-** must be called one or more times to evaluate the statement.
-**
-** The details of the behavior of the sqlite3_step() interface depend

-** [sqlite3_prepare_v3()], [sqlite3_prepare_v2()], [sqlite3_prepare16_v3()],
-** [sqlite3_prepare16_v2()] or the older legacy
-** interfaces [sqlite3_prepare()] and [sqlite3_prepare16()].  The use of the
-** new "vX" interface is recommended for new applications but the legacy
-** interface will continue to be supported.
-**
-** ^In the legacy interface, the return value will be either [SQLITE_BUSY],
-** [SQLITE_DONE], [SQLITE_ROW], [SQLITE_ERROR], or [SQLITE_MISUSE].
-** ^With the "v2" interface, any of the other [result codes] or
-** [extended result codes] might be returned as well.
-**
-** ^[SQLITE_BUSY] means that the database engine was unable to acquire the
-** database locks it needs to do its job.  ^If the statement is a [COMMIT]
-** or occurs outside of an explicit transaction, then you can retry the
-** statement.  If the statement is not a [COMMIT] and occurs within an
-** explicit transaction then you should rollback the transaction before
-** continuing.
-**
-** ^[SQLITE_DONE] means that the statement has finished executing
-** successfully.  sqlite3_step() should not be called again on this virtual
-** machine without first calling [sqlite3_reset()] to reset the virtual
-** machine back to its initial state.
-**
-** ^If the SQL statement being executed returns any data, then [SQLITE_ROW]
-** is returned each time a new row of data is ready for processing by the
-** caller. The values may be accessed using the [column access functions].
-** sqlite3_step() is called again to retrieve the next row of data.
-**
-** ^[SQLITE_ERROR] means that a run-time error (such as a constraint
-** violation) has occurred.  sqlite3_step() should not be called again on
-** the VM. More information may be found by calling [sqlite3_errmsg()].
-** ^With the legacy interface, a more specific error code (for example,
-** [SQLITE_INTERRUPT], [SQLITE_SCHEMA], [SQLITE_CORRUPT], and so forth)
-** can be obtained by calling [sqlite3_reset()] on the
-** [prepared statement].  ^In the "v2" interface,
-** the more specific error code is returned directly by sqlite3_step().
-**
-** [SQLITE_MISUSE] means that the this routine was called inappropriately.
-** Perhaps it was called on a [prepared statement] that has
-** already been [sqlite3_finalize | finalized] or on one that had
-** previously returned [SQLITE_ERROR] or [SQLITE_DONE].  Or it could
-** be the case that the same database connection is being used by two or
-** more threads at the same moment in time.
-**
-** For all versions of SQLite up to and including 3.6.23.1, a call to
-** [sqlite3_reset()] was required after sqlite3_step() returned anything
-** other than [SQLITE_ROW] before any subsequent invocation of
-** sqlite3_step().  Failure to reset the prepared statement using
-** [sqlite3_reset()] would result in an [SQLITE_MISUSE] return from
-** sqlite3_step().  But after [version 3.6.23.1] ([dateof:3.6.23.1],
-** sqlite3_step() began
-** calling [sqlite3_reset()] automatically in this circumstance rather
-** than returning [SQLITE_MISUSE].  This is not considered a compatibility
-** break because any application that ever receives an SQLITE_MISUSE error
-** is broken by definition.  The [SQLITE_OMIT_AUTORESET] compile-time option
-** can be used to restore the legacy behavior.
-**
-** <b>Goofy Interface Alert:</b> In the legacy interface, the sqlite3_step()
-** API always returns a generic error code, [SQLITE_ERROR], following any
-** error other than [SQLITE_BUSY] and [SQLITE_MISUSE].  You must call
-** [sqlite3_reset()] or [sqlite3_finalize()] in order to find one of the
-** specific [error codes] that better describes the error.
-** We admit that this is a goofy design.  The problem has been fixed

-** <b>Details:</b>
-**
-** ^These routines return information about a single column of the current
-** result row of a query.  ^In every case the first argument is a pointer
-** to the [prepared statement] that is being evaluated (the [sqlite3_stmt*]
-** that was returned from [sqlite3_prepare_v2()] or one of its variants)
-** and the second argument is the index of the column for which information
-** should be returned. ^The leftmost column of the result set has the index 0.
-** ^The number of columns in the result can be determined using
-** [sqlite3_column_count()].
-**
-** If the SQL statement does not currently point to a valid row, or if the
-** column index is out of range, the result is undefined.
-** These routines may only be called when the most recent call to
-** [sqlite3_step()] has returned [SQLITE_ROW] and neither
-** [sqlite3_reset()] nor [sqlite3_finalize()] have been called subsequently.
-** If any of these routines are called after [sqlite3_reset()] or
-** [sqlite3_finalize()] or after [sqlite3_step()] has returned
-** something other than [SQLITE_ROW], the results are undefined.
-** If [sqlite3_step()] or [sqlite3_reset()] or [sqlite3_finalize()]
-** are called from a different thread while any of these routines
-** are pending, then the results are undefined.
-**
-** The first six interfaces (_blob, _double, _int, _int64, _text, and _text16)
-** each return the value of a result column in a specific data format.  If
-** the result column is not initially in the requested format (for example,
-** if the query returns an integer but the sqlite3_column_text() interface
-** is used to extract the value) then an automatic type conversion is performed.
-**
-** ^The sqlite3_column_type() routine returns the
-** [SQLITE_INTEGER | datatype code] for the initial data type
-** of the result column.  ^The returned value is one of [SQLITE_INTEGER],
-** [SQLITE_FLOAT], [SQLITE_TEXT], [SQLITE_BLOB], or [SQLITE_NULL].
-** The return value of sqlite3_column_type() can be used to decide which
-** of the first six interface should be used to extract the column value.
-** The value returned by sqlite3_column_type() is only meaningful if no
-** automatic type conversions have occurred for the value in question.
-** After a type conversion, the result of calling sqlite3_column_type()
-** is undefined, though harmless.  Future
-** versions of SQLite may change the behavior of sqlite3_column_type()
-** following a type conversion.
-**
-** If the result is a BLOB or a TEXT string, then the sqlite3_column_bytes()
-** or sqlite3_column_bytes16() interfaces can be used to determine the size
-** of that BLOB or string.
-**
-** ^If the result is a BLOB or UTF-8 string then the sqlite3_column_bytes()
-** routine returns the number of bytes in that BLOB or string.
-** ^If the result is a UTF-16 string, then sqlite3_column_bytes() converts
-** the string to UTF-8 and then returns the number of bytes.
-** ^If the result is a numeric value then sqlite3_column_bytes() uses
-** [sqlite3_snprintf()] to convert that value to a UTF-8 string and returns
-** the number of bytes in that string.
-** ^If the result is NULL, then sqlite3_column_bytes() returns zero.
-**
-** ^If the result is a BLOB or UTF-16 string then the sqlite3_column_bytes16()
-** routine returns the number of bytes in that BLOB or string.
-** ^If the result is a UTF-8 string, then sqlite3_column_bytes16() converts
-** the string to UTF-16 and then returns the number of bytes.
-** ^If the result is a numeric value then sqlite3_column_bytes16() uses
-** [sqlite3_snprintf()] to convert that value to a UTF-16 string and returns
-** the number of bytes in that string.
-** ^If the result is NULL, then sqlite3_column_bytes16() returns zero.
-**
-** ^The values returned by [sqlite3_column_bytes()] and
-** [sqlite3_column_bytes16()] do not include the zero terminators at the end
-** of the string.  ^For clarity: the values returned by
-** [sqlite3_column_bytes()] and [sqlite3_column_bytes16()] are the number of
-** bytes in the string, not the number of characters.
-**
-** ^Strings returned by sqlite3_column_text() and sqlite3_column_text16(),
-** even empty strings, are always zero-terminated.  ^The return
-** value from sqlite3_column_blob() for a zero-length BLOB is a NULL pointer.
-**
-** ^Strings returned by sqlite3_column_text16() always have the endianness
-** which is native to the platform, regardless of the text encoding set
-** for the database.
-**
-** <b>Warning:</b> ^The object returned by [sqlite3_column_value()] is an
-** [unprotected sqlite3_value] object.  In a multithreaded environment,
-** an unprotected sqlite3_value object may only be used safely with
-** [sqlite3_bind_value()] and [sqlite3_result_value()].
-** If the [unprotected sqlite3_value] object returned by
-** [sqlite3_column_value()] is used in any other way, including calls
-** to routines like [sqlite3_value_int()], [sqlite3_value_text()],
-** or [sqlite3_value_bytes()], the behavior is not threadsafe.
-** Hence, the sqlite3_column_value() interface
-** is normally only useful within the implementation of
-** [application-defined SQL functions] or [virtual tables], not within
-** top-level application code.
-**
-** These routines may attempt to convert the datatype of the result.
-** ^For example, if the internal representation is FLOAT and a text result
-** is requested, [sqlite3_snprintf()] is used internally to perform the
-** conversion automatically.  ^(The following table details the conversions
-** that are applied:
-**
-** <blockquote>
-** <table border="1">
-** <tr><th> Internal<br>Type <th> Requested<br>Type <th>  Conversion
-**
-** <tr><td>  NULL    <td> INTEGER   <td> Result is 0

-** <tr><td>  NULL    <td>   TEXT    <td> Result is a NULL pointer
-** <tr><td>  NULL    <td>   BLOB    <td> Result is a NULL pointer
-** <tr><td> INTEGER  <td>  FLOAT    <td> Convert from integer to float
-** <tr><td> INTEGER  <td>   TEXT    <td> ASCII rendering of the integer
-** <tr><td> INTEGER  <td>   BLOB    <td> Same as INTEGER->TEXT
-** <tr><td>  FLOAT   <td> INTEGER   <td> [CAST] to INTEGER
-** <tr><td>  FLOAT   <td>   TEXT    <td> ASCII rendering of the float
-** <tr><td>  FLOAT   <td>   BLOB    <td> [CAST] to BLOB

-**
-** Note that when type conversions occur, pointers returned by prior
-** calls to sqlite3_column_blob(), sqlite3_column_text(), and/or
-** sqlite3_column_text16() may be invalidated.
-** Type conversions and pointer invalidations might occur
-** in the following cases:
-**
-** <ul>
-** <li> The initial content is a BLOB and sqlite3_column_text() or
-**      sqlite3_column_text16() is called.  A zero-terminator might
-**      need to be added to the string.</li>
-** <li> The initial content is UTF-8 text and sqlite3_column_bytes16() or
-**      sqlite3_column_text16() is called.  The content must be converted
-**      to UTF-16.</li>
-** <li> The initial content is UTF-16 text and sqlite3_column_bytes() or
-**      sqlite3_column_text() is called.  The content must be converted
-**      to UTF-8.</li>
-** </ul>
-**
-** ^Conversions between UTF-16be and UTF-16le are always done in place and do
-** not invalidate a prior pointer, though of course the content of the buffer
-** that the prior pointer references will have been modified.  Other kinds
-** of conversion are done in place when it is possible, but sometimes they
-** are not possible and in those cases prior pointers are invalidated.
-**
-** The safest policy is to invoke these routines
-** in one of the following ways:
-**
-** <ul>
-**  <li>sqlite3_column_text() followed by sqlite3_column_bytes()</li>
-**  <li>sqlite3_column_blob() followed by sqlite3_column_bytes()</li>
-**  <li>sqlite3_column_text16() followed by sqlite3_column_bytes16()</li>
-** </ul>
-**
-** In other words, you should call sqlite3_column_text(),
-** sqlite3_column_blob(), or sqlite3_column_text16() first to force the result
-** into the desired format, then invoke sqlite3_column_bytes() or
-** sqlite3_column_bytes16() to find the size of the result.  Do not mix calls
-** to sqlite3_column_text() or sqlite3_column_blob() with calls to
-** sqlite3_column_bytes16(), and do not mix calls to sqlite3_column_text16()
-** with calls to sqlite3_column_bytes().
-**
-** ^The pointers returned are valid until a type conversion occurs as
-** described above, or until [sqlite3_step()] or [sqlite3_reset()] or
-** [sqlite3_finalize()] is called.  ^The memory space used to hold strings
-** and BLOBs is freed automatically.  Do not pass the pointers returned
-** from [sqlite3_column_blob()], [sqlite3_column_text()], etc. into
-** [sqlite3_free()].
-**
-** As long as the input parameters are correct, these routines will only
-** fail if an out-of-memory error occurs during a format conversion.
-** Only the following subset of interfaces are subject to out-of-memory
-** errors:
-**
-** <ul>
-** <li> sqlite3_column_blob()
-** <li> sqlite3_column_text()
-** <li> sqlite3_column_text16()
-** <li> sqlite3_column_bytes()
-** <li> sqlite3_column_bytes16()
-** </ul>
-**
-** If an out-of-memory error occurs, then the return value from these
-** routines is the same as if the column had contained an SQL NULL value.
-** Valid SQL NULL returns can be distinguished from out-of-memory errors
-** by invoking the [sqlite3_errcode()] immediately after the suspect
-** return value is obtained and before any
-** other SQLite interface is called on the same [database connection].

-** CAPI3REF: Create Or Redefine SQL Functions
-** KEYWORDS: {function creation routines}
-** METHOD: sqlite3
-**
-** ^These functions (collectively known as "function creation routines")
-** are used to add SQL functions or aggregates or to redefine the behavior
-** of existing SQL functions or aggregates. The only differences between
-** the three "sqlite3_create_function*" routines are the text encoding
-** expected for the second parameter (the name of the function being
-** created) and the presence or absence of a destructor callback for
-** the application data pointer. Function sqlite3_create_window_function()
-** is similar, but allows the user to supply the extra callback functions
-** needed by [aggregate window functions].
-**
-** ^The first parameter is the [database connection] to which the SQL
-** function is to be added.  ^If an application uses more than one database
-** connection then application-defined SQL functions must be added
-** to each database connection separately.
-**
-** ^The second parameter is the name of the SQL function to be created or
-** redefined.  ^The length of the name is limited to 255 bytes in a UTF-8
-** representation, exclusive of the zero-terminator.  ^Note that the name
-** length limit is in UTF-8 bytes, not characters nor UTF-16 bytes.
-** ^Any attempt to create a function with a longer name
-** will result in [SQLITE_MISUSE] being returned.
-**
-** ^The third parameter (nArg)
-** is the number of arguments that the SQL function or
-** aggregate takes. ^If this parameter is -1, then the SQL function or
-** aggregate may take any number of arguments between 0 and the limit
-** set by [sqlite3_limit]([SQLITE_LIMIT_FUNCTION_ARG]).  If the third
-** parameter is less than -1 or greater than 127 then the behavior is
-** undefined.
-**
-** ^The fourth parameter, eTextRep, specifies what
-** [SQLITE_UTF8 | text encoding] this SQL function prefers for
-** its parameters.  The application should set this parameter to
-** [SQLITE_UTF16LE] if the function implementation invokes
-** [sqlite3_value_text16le()] on an input, or [SQLITE_UTF16BE] if the
-** implementation invokes [sqlite3_value_text16be()] on an input, or
-** [SQLITE_UTF16] if [sqlite3_value_text16()] is used, or [SQLITE_UTF8]
-** otherwise.  ^The same SQL function may be registered multiple times using
-** different preferred text encodings, with different implementations for
-** each encoding.
-** ^When multiple implementations of the same function are available, SQLite
-** will pick the one that involves the least amount of data conversion.
-**
-** ^The fourth parameter may optionally be ORed with [SQLITE_DETERMINISTIC]
-** to signal that the function will always return the same result given
-** the same inputs within a single SQL statement.  Most SQL functions are
-** deterministic.  The built-in [random()] SQL function is an example of a
-** function that is not deterministic.  The SQLite query planner is able to
-** perform additional optimizations on deterministic functions, so use
-** of the [SQLITE_DETERMINISTIC] flag is recommended where possible.
-**
-** ^The fourth parameter may also optionally include the [SQLITE_DIRECTONLY]
-** flag, which if present prevents the function from being invoked from
-** within VIEWs, TRIGGERs, CHECK constraints, generated column expressions,
-** index expressions, or the WHERE clause of partial indexes.
-**
-** For best security, the [SQLITE_DIRECTONLY] flag is recommended for
-** all application-defined SQL functions that do not need to be
-** used inside of triggers, view, CHECK constraints, or other elements of
-** the database schema.  This flags is especially recommended for SQL
-** functions that have side effects or reveal internal application state.
-** Without this flag, an attacker might be able to modify the schema of
-** a database file to include invocations of the function with parameters
-** chosen by the attacker, which the application will then execute when
-** the database file is opened and read.
-**
-** ^(The fifth parameter is an arbitrary pointer.  The implementation of the
-** function can gain access to this pointer using [sqlite3_user_data()].)^
-**
-** ^The sixth, seventh and eighth parameters passed to the three
-** "sqlite3_create_function*" functions, xFunc, xStep and xFinal, are
-** pointers to C-language functions that implement the SQL function or
-** aggregate. ^A scalar SQL function requires an implementation of the xFunc
-** callback only; NULL pointers must be passed as the xStep and xFinal
-** parameters. ^An aggregate SQL function requires an implementation of xStep
-** and xFinal and NULL pointer must be passed for xFunc. ^To delete an existing
-** SQL function or aggregate, pass NULL pointers for all three function
-** callbacks.
-**
-** ^The sixth, seventh, eighth and ninth parameters (xStep, xFinal, xValue
-** and xInverse) passed to sqlite3_create_window_function are pointers to
-** C-language callbacks that implement the new function. xStep and xFinal
-** must both be non-NULL. xValue and xInverse may either both be NULL, in
-** which case a regular aggregate function is created, or must both be
-** non-NULL, in which case the new function may be used as either an aggregate
-** or aggregate window function. More details regarding the implementation
-** of aggregate window functions are
-** [user-defined window functions|available here].
-**
-** ^(If the final parameter to sqlite3_create_function_v2() or
-** sqlite3_create_window_function() is not NULL, then it is destructor for
-** the application data pointer. The destructor is invoked when the function
-** is deleted, either by being overloaded or when the database connection
-** closes.)^ ^The destructor is also invoked if the call to
-** sqlite3_create_function_v2() fails.  ^When the destructor callback is
-** invoked, it is passed a single argument which is a copy of the application
-** data pointer which was the fifth parameter to sqlite3_create_function_v2().
-**
-** ^It is permitted to register multiple implementations of the same
-** functions with the same name but with either differing numbers of
-** arguments or differing preferred text encodings.  ^SQLite will use
-** the implementation that most closely matches the way in which the
-** SQL function is used.  ^A function implementation with a non-negative
-** nArg parameter is a better match than a function implementation with
-** a negative nArg.  ^A function where the preferred text encoding
-** matches the database encoding is a better
-** match than a function where the encoding is different.
-** ^A function where the encoding difference is between UTF16le and UTF16be
-** is a closer match than a function where the encoding difference is
-** between UTF8 and UTF16.
-**
-** ^Built-in functions may be overloaded by new application-defined functions.
-**
-** ^An application-defined function is permitted to call other
-** SQLite interfaces.  However, such calls must not
-** close the database connection nor finalize or reset the prepared
-** statement in which the function is running.

-** [[SQLITE_DETERMINISTIC]] <dt>SQLITE_DETERMINISTIC</dt><dd>
-** The SQLITE_DETERMINISTIC flag means that the new function always gives
-** the same output when the input parameters are the same.
-** The [abs|abs() function] is deterministic, for example, but
-** [randomblob|randomblob()] is not.  Functions must
-** be deterministic in order to be used in certain contexts such as
-** with the WHERE clause of [partial indexes] or in [generated columns].
-** SQLite might also optimize deterministic functions by factoring them
-** out of inner loops.
-** </dd>
-**
-** [[SQLITE_DIRECTONLY]] <dt>SQLITE_DIRECTONLY</dt><dd>
-** The SQLITE_DIRECTONLY flag means that the function may only be invoked
-** from top-level SQL, and cannot be used in VIEWs or TRIGGERs nor in
-** schema structures such as [CHECK constraints], [DEFAULT clauses],
-** [expression indexes], [partial indexes], or [generated columns].
-** <p>
-** The SQLITE_DIRECTONLY flag is recommended for any
-** [application-defined SQL function]
-** that has side-effects or that could potentially leak sensitive information.
-** This will prevent attacks in which an application is tricked
-** into using a database file that has had its schema surreptitiously
-** modified to invoke the application-defined function in ways that are
-** harmful.
-** <p>
-** Some people say it is good practice to set SQLITE_DIRECTONLY on all
-** [application-defined SQL functions], regardless of whether or not they
-** are security sensitive, as doing so prevents those functions from being used
-** inside of the database schema, and thus ensures that the database
-** can be inspected and modified using generic tools (such as the [CLI])
-** that do not have access to the application-defined functions.
-** </dd>
-**
-** [[SQLITE_INNOCUOUS]] <dt>SQLITE_INNOCUOUS</dt><dd>
-** The SQLITE_INNOCUOUS flag means that the function is unlikely
-** to cause problems even if misused.  An innocuous function should have
-** no side effects and should not depend on any values other than its
-** input parameters. The [abs|abs() function] is an example of an
-** innocuous function.
-** The [load_extension() SQL function] is not innocuous because of its
-** side effects.
-** <p> SQLITE_INNOCUOUS is similar to SQLITE_DETERMINISTIC, but is not
-** exactly the same.  The [random|random() function] is an example of a
-** function that is innocuous but not deterministic.
-** <p>Some heightened security settings
-** ([SQLITE_DBCONFIG_TRUSTED_SCHEMA] and [PRAGMA trusted_schema=OFF])
-** disable the use of SQL functions inside views and triggers and in
-** schema structures such as [CHECK constraints], [DEFAULT clauses],
-** [expression indexes], [partial indexes], and [generated columns] unless
-** the function is tagged with SQLITE_INNOCUOUS.  Most built-in functions
-** are innocuous.  Developers are advised to avoid using the
-** SQLITE_INNOCUOUS flag for application-defined functions unless the

-** security-adverse side-effects and information-leaks.
-** </dd>
-**
-** [[SQLITE_SUBTYPE]] <dt>SQLITE_SUBTYPE</dt><dd>
-** The SQLITE_SUBTYPE flag indicates to SQLite that a function might call

-** This flag instructs SQLite to omit some corner-case optimizations that
-** might disrupt the operation of the [sqlite3_value_subtype()] function,
-** causing it to return zero rather than the correct subtype().
-** SQL functions that invokes [sqlite3_value_subtype()] should have this
-** property.  If the SQLITE_SUBTYPE property is omitted, then the return

-**
-** <b>Details:</b>
-**
-** These routines extract type, size, and content information from
-** [protected sqlite3_value] objects.  Protected sqlite3_value objects
-** are used to pass parameter information into the functions that
-** implement [application-defined SQL functions] and [virtual tables].
-**
-** These routines work only with [protected sqlite3_value] objects.
-** Any attempt to use these routines on an [unprotected sqlite3_value]
-** is not threadsafe.
-**
-** ^These routines work just like the corresponding [column access functions]
-** except that these routines take a single [protected sqlite3_value] object
-** pointer instead of a [sqlite3_stmt*] pointer and an integer column number.
-**
-** ^The sqlite3_value_text16() interface extracts a UTF-16 string
-** in the native byte-order of the host machine.  ^The
-** sqlite3_value_text16be() and sqlite3_value_text16le() interfaces
-** extract UTF-16 strings as big-endian and little-endian respectively.
-**
-** ^If [sqlite3_value] object V was initialized
-** using [sqlite3_bind_pointer(S,I,P,X,D)] or [sqlite3_result_pointer(C,P,X,D)]
-** and if X and Y are strings that compare equal according to strcmp(X,Y),
-** then sqlite3_value_pointer(V,Y) will return the pointer P.  ^Otherwise,
-** sqlite3_value_pointer(V,Y) returns a NULL. The sqlite3_bind_pointer()
-** routine is part of the [pointer passing interface] added for SQLite 3.20.0.
-**
-** ^(The sqlite3_value_type(V) interface returns the
-** [SQLITE_INTEGER | datatype code] for the initial datatype of the
-** [sqlite3_value] object V. The returned value is one of [SQLITE_INTEGER],
-** [SQLITE_FLOAT], [SQLITE_TEXT], [SQLITE_BLOB], or [SQLITE_NULL].)^
-** Other interfaces might change the datatype for an sqlite3_value object.
-** For example, if the datatype is initially SQLITE_INTEGER and
-** sqlite3_value_text(V) is called to extract a text value for that
-** integer, then subsequent calls to sqlite3_value_type(V) might return
-** SQLITE_TEXT.  Whether or not a persistent internal datatype conversion
-** occurs is undefined and may change from one release of SQLite to the next.
-**
-** ^(The sqlite3_value_numeric_type() interface attempts to apply
-** numeric affinity to the value.  This means that an attempt is
-** made to convert the value to an integer or floating point.  If
-** such a conversion is possible without loss of information (in other
-** words, if the value is a string that looks like a number)
-** then the conversion is performed.  Otherwise no conversion occurs.
-** The [SQLITE_INTEGER | datatype] after conversion is returned.)^
-**
-** ^Within the [xUpdate] method of a [virtual table], the
-** sqlite3_value_nochange(X) interface returns true if and only if
-** the column corresponding to X is unchanged by the UPDATE operation
-** that the xUpdate method call was invoked to implement and if
-** and the prior [xColumn] method call that was invoked to extracted
-** the value for that column returned without setting a result (probably
-** because it queried [sqlite3_vtab_nochange()] and found that the column
-** was unchanging).  ^Within an [xUpdate] method, any value for which
-** sqlite3_value_nochange(X) is true will in all other respects appear
-** to be a NULL value.  If sqlite3_value_nochange(X) is invoked anywhere other
-** than within an [xUpdate] method call for an UPDATE statement, then
-** the return value is arbitrary and meaningless.
-**
-** ^The sqlite3_value_frombind(X) interface returns non-zero if the
-** value X originated from one of the [sqlite3_bind_int|sqlite3_bind()]
-** interfaces.  ^If X comes from an SQL literal value, or a table column,
-** or an expression, then sqlite3_value_frombind(X) returns zero.
-**
-** Please pay particular attention to the fact that the pointer returned
-** from [sqlite3_value_blob()], [sqlite3_value_text()], or
-** [sqlite3_value_text16()] can be invalidated by a subsequent call to
-** [sqlite3_value_bytes()], [sqlite3_value_bytes16()], [sqlite3_value_text()],
-** or [sqlite3_value_text16()].
-**
-** These routines must be called from the same thread as
-** the SQL function that supplied the [sqlite3_value*] parameters.
-**
-** As long as the input parameter is correct, these routines can only
-** fail if an out-of-memory error occurs during a format conversion.
-** Only the following subset of interfaces are subject to out-of-memory
-** errors:
-**
-** <ul>
-** <li> sqlite3_value_blob()
-** <li> sqlite3_value_text()
-** <li> sqlite3_value_text16()
-** <li> sqlite3_value_text16le()
-** <li> sqlite3_value_text16be()
-** <li> sqlite3_value_bytes()
-** <li> sqlite3_value_bytes16()
-** </ul>
-**
-** If an out-of-memory error occurs, then the return value from these
-** routines is the same as if the column had contained an SQL NULL value.
-** Valid SQL NULL returns can be distinguished from out-of-memory errors
-** by invoking the [sqlite3_errcode()] immediately after the suspect
-** return value is obtained and before any
-** other SQLite interface is called on the same [database connection].

-** an aggregate query, the xStep() callback of the aggregate function
-** implementation is never called and xFinal() is called exactly once.
-** In those cases, sqlite3_aggregate_context() might be called for the
-** first time from within xFinal().)^
-**
-** ^The sqlite3_aggregate_context(C,N) routine returns a NULL pointer
-** when first called if N is less than or equal to zero or if a memory
-** allocation error occurs.
-**
-** ^(The amount of space allocated by sqlite3_aggregate_context(C,N) is

-** query execution, under some circumstances the associated auxiliary data
-** might be preserved.  An example of where this might be useful is in a
-** regular-expression matching function. The compiled version of the regular
-** expression can be stored as auxiliary data associated with the pattern string.
-** Then as long as the pattern string remains the same,
-** the compiled regular expression can be reused on multiple
-** invocations of the same function.
-**
-** ^The sqlite3_get_auxdata(C,N) interface returns a pointer to the auxiliary data
-** associated by the sqlite3_set_auxdata(C,N,P,X) function with the Nth argument
-** value to the application-defined function.  ^N is zero for the left-most
-** function argument.  ^If there is no auxiliary data
-** associated with the function argument, the sqlite3_get_auxdata(C,N) interface
-** returns a NULL pointer.
-**
-** ^The sqlite3_set_auxdata(C,N,P,X) interface saves P as auxiliary data for the
-** N-th argument of the application-defined function.  ^Subsequent
-** calls to sqlite3_get_auxdata(C,N) return P from the most recent
-** sqlite3_set_auxdata(C,N,P,X) call if the auxiliary data is still valid or
-** NULL if the auxiliary data has been discarded.
-** ^After each call to sqlite3_set_auxdata(C,N,P,X) where X is not NULL,
-** SQLite will invoke the destructor function X with parameter P exactly
-** once, when the auxiliary data is discarded.
-** SQLite is free to discard the auxiliary data at any time, including: <ul>
-** <li> ^(when the corresponding function parameter changes)^, or
-** <li> ^(when [sqlite3_reset()] or [sqlite3_finalize()] is called for the
-**      SQL statement)^, or
-** <li> ^(when sqlite3_set_auxdata() is invoked again on the same

-**      is evaluated during query planning instead of during query execution,
-**      as sometimes happens with [SQLITE_ENABLE_STAT4].)^ </ul>
-**
-** Note the last two bullets in particular.  The destructor X in
-** sqlite3_set_auxdata(C,N,P,X) might be called immediately, before the
-** sqlite3_set_auxdata() interface even returns.  Hence sqlite3_set_auxdata()
-** should be called near the end of the function implementation and the
-** function implementation should not make any use of P after
-** sqlite3_set_auxdata() has been called.  Furthermore, a call to
-** sqlite3_get_auxdata() that occurs immediately after a corresponding call
-** to sqlite3_set_auxdata() might still return NULL if an out-of-memory
-** condition occurred during the sqlite3_set_auxdata() call or if the

-**
-** If P and X are both non-NULL, then the destructor X is invoked with

-** <ul>
-** <li> An out-of-memory error occurs during the call to

-**
-** SQLite does not do anything with client data other than invoke

-**
-** There is no limit (other than available memory) on the number of different
-** client data pointers (with different names) that can be attached to a
-** single database connection.  However, the implementation is optimized
-** for the case of having only one or two different client data names.
-** Applications and wrapper libraries are discouraged from using more than

-** for additional information.
-**
-** These functions work very much like the [parameter binding] family of
-** functions used to bind values to host parameters in prepared statements.
-** Refer to the [SQL parameter] documentation for additional information.
-**
-** ^The sqlite3_result_blob() interface sets the result from
-** an application-defined function to be the BLOB whose content is pointed

-** third parameter.
-**
-** ^The sqlite3_result_zeroblob(C,N) and sqlite3_result_zeroblob64(C,N)
-** interfaces set the result of the application-defined function to be
-** a BLOB containing all zero bytes and N bytes in size.
-**
-** ^The sqlite3_result_double() interface sets the result from
-** an application-defined function to be a floating point value specified
-** by its 2nd argument.
-**
-** ^The sqlite3_result_error() and sqlite3_result_error16() functions
-** cause the implemented SQL function to throw an exception.
-** ^SQLite uses the string pointed to by the
-** 2nd parameter of sqlite3_result_error() or sqlite3_result_error16()
-** as the text of an error message.  ^SQLite interprets the error
-** message string from sqlite3_result_error() as UTF-8. ^SQLite
-** interprets the string from sqlite3_result_error16() as UTF-16 using
-** the same [byte-order determination rules] as [sqlite3_bind_text16()].
-** ^If the third parameter to sqlite3_result_error()
-** or sqlite3_result_error16() is negative then SQLite takes as the error
-** message all text up through the first zero character.
-** ^If the third parameter to sqlite3_result_error() or
-** sqlite3_result_error16() is non-negative then SQLite takes that many
-** bytes (not characters) from the 2nd parameter as the error message.
-** ^The sqlite3_result_error() and sqlite3_result_error16()
-** routines make a private copy of the error message text before
-** they return.  Hence, the calling function can deallocate or
-** modify the text after they return without harm.
-** ^The sqlite3_result_error_code() function changes the error code
-** returned by SQLite as a result of an error in a function.  ^By default,
-** the error code is SQLITE_ERROR.  ^A subsequent call to sqlite3_result_error()
-** or sqlite3_result_error16() resets the error code to SQLITE_ERROR.
-**
-** ^The sqlite3_result_error_toobig() interface causes SQLite to throw an
-** error indicating that a string or BLOB is too long to represent.
-**
-** ^The sqlite3_result_error_nomem() interface causes SQLite to throw an
-** error indicating that a memory allocation failed.
-**
-** ^The sqlite3_result_int() interface sets the return value
-** of the application-defined function to be the 32-bit signed integer
-** value given in the 2nd argument.
-** ^The sqlite3_result_int64() interface sets the return value
-** of the application-defined function to be the 64-bit signed integer
-** value given in the 2nd argument.
-**
-** ^The sqlite3_result_null() interface sets the return value
-** of the application-defined function to be NULL.
-**
-** ^The sqlite3_result_text(), sqlite3_result_text16(),
-** sqlite3_result_text16le(), and sqlite3_result_text16be() interfaces
-** set the return value of the application-defined function to be
-** a text string which is represented as UTF-8, UTF-16 native byte order,
-** UTF-16 little endian, or UTF-16 big endian, respectively.
-** ^The sqlite3_result_text64() interface sets the return value of an
-** application-defined function to be a text string in an encoding
-** specified by the fifth (and last) parameter, which must be one
-** of [SQLITE_UTF8], [SQLITE_UTF16], [SQLITE_UTF16BE], or [SQLITE_UTF16LE].
-** ^SQLite takes the text result from the application from
-** the 2nd parameter of the sqlite3_result_text* interfaces.
-** ^If the 3rd parameter to any of the sqlite3_result_text* interfaces
-** other than sqlite3_result_text64() is negative, then SQLite computes
-** the string length itself by searching the 2nd parameter for the first
-** zero character.
-** ^If the 3rd parameter to the sqlite3_result_text* interfaces
-** is non-negative, then as many bytes (not characters) of the text
-** pointed to by the 2nd parameter are taken as the application-defined
-** function result.  If the 3rd parameter is non-negative, then it
-** must be the byte offset into the string where the NUL terminator would
-** appear if the string where NUL terminated.  If any NUL characters occur
-** in the string at a byte offset that is less than the value of the 3rd
-** parameter, then the resulting string will contain embedded NULs and the
-** result of expressions operating on strings with embedded NULs is undefined.
-** ^If the 4th parameter to the sqlite3_result_text* interfaces
-** or sqlite3_result_blob is a non-NULL pointer, then SQLite calls that
-** function as the destructor on the text or BLOB result when it has
-** finished using that result.
-** ^If the 4th parameter to the sqlite3_result_text* interfaces or to
-** sqlite3_result_blob is the special constant SQLITE_STATIC, then SQLite
-** assumes that the text or BLOB result is in constant space and does not
-** copy the content of the parameter nor call a destructor on the content
-** when it has finished using that result.
-** ^If the 4th parameter to the sqlite3_result_text* interfaces
-** or sqlite3_result_blob is the special constant SQLITE_TRANSIENT
-** then SQLite makes a copy of the result into space obtained
-** from [sqlite3_malloc()] before it returns.
-**
-** ^For the sqlite3_result_text16(), sqlite3_result_text16le(), and
-** sqlite3_result_text16be() routines, and for sqlite3_result_text64()
-** when the encoding is not UTF8, if the input UTF16 begins with a
-** byte-order mark (BOM, U+FEFF) then the BOM is removed from the
-** string and the rest of the string is interpreted according to the
-** byte-order specified by the BOM.  ^The byte-order specified by
-** the BOM at the beginning of the text overrides the byte-order
-** specified by the interface procedure.  ^So, for example, if
-** sqlite3_result_text16le() is invoked with text that begins
-** with bytes 0xfe, 0xff (a big-endian byte-order mark) then the
-** first two bytes of input are skipped and the remaining input
-** is interpreted as UTF16BE text.
-**
-** ^For UTF16 input text to the sqlite3_result_text16(),
-** sqlite3_result_text16be(), sqlite3_result_text16le(), and
-** sqlite3_result_text64() routines, if the text contains invalid
-** UTF16 characters, the invalid characters might be converted
-** into the unicode replacement character, U+FFFD.
-**
-** ^The sqlite3_result_value() interface sets the result of
-** the application-defined function to be a copy of the
-** [unprotected sqlite3_value] object specified by the 2nd parameter.  ^The
-** sqlite3_result_value() interface makes a copy of the [sqlite3_value]
-** so that the [sqlite3_value] specified in the parameter may change or
-** be deallocated after sqlite3_result_value() returns without harm.
-** ^A [protected sqlite3_value] object may always be used where an
-** [unprotected sqlite3_value] object is required, so either
-** kind of [sqlite3_value] object can be used with this interface.
-**
-** ^The sqlite3_result_pointer(C,P,T,D) interface sets the result to an
-** SQL NULL value, just like [sqlite3_result_null(C)], except that it
-** also associates the host-language pointer P or type T with that

-** sequence is required.
-**
-** ^If the function is registered using the sqlite3_collation_needed() API,

-** ^A call to either function replaces the existing collation-needed callback.
-**
-** ^(When the callback is invoked, the first argument passed is a copy
-** of the second argument to sqlite3_collation_needed() or
-** sqlite3_collation_needed16().  The second argument is the database
-** connection.  The third argument is one of [SQLITE_UTF8], [SQLITE_UTF16BE],
-** or [SQLITE_UTF16LE], indicating the most desirable form of the collation
-** sequence function required.  The fourth parameter is the name of the

-**
-** These interfaces impose limits on the amount of heap memory that will be
-** by all database connections within a single process.
-**
-** ^The sqlite3_soft_heap_limit64() interface sets and/or queries the
-** soft limit on the amount of heap memory that may be allocated by SQLite.
-** ^SQLite strives to keep heap memory utilization below the soft heap
-** limit by reducing the number of pages held in the page cache
-** as heap memory usages approaches the limit.
-** ^The soft heap limit is "soft" because even though SQLite strives to stay
-** below the limit, it will exceed the limit rather than generate
-** an [SQLITE_NOMEM] error.  In other words, the soft heap limit
-** is advisory only.
-**
-** ^The sqlite3_hard_heap_limit64(N) interface sets a hard upper bound of
-** N bytes on the amount of memory that will be allocated.  ^The
-** sqlite3_hard_heap_limit64(N) interface is similar to
-** sqlite3_soft_heap_limit64(N) except that memory allocations will fail
-** when the hard heap limit is reached.
-**
-** ^The return value from both sqlite3_soft_heap_limit64() and
-** sqlite3_hard_heap_limit64() is the size of
-** the heap limit prior to the call, or negative in the case of an
-** error.  ^If the argument N is negative
-** then no change is made to the heap limit.  Hence, the current
-** size of heap limits can be determined by invoking
-** sqlite3_soft_heap_limit64(-1) or sqlite3_hard_heap_limit(-1).
-**
-** ^Setting the heap limits to zero disables the heap limiter mechanism.
-**
-** ^The soft heap limit may not be greater than the hard heap limit.
-** ^If the hard heap limit is enabled and if sqlite3_soft_heap_limit(N)
-** is invoked with a value of N that is greater than the hard heap limit,
-** the soft heap limit is set to the value of the hard heap limit.
-** ^The soft heap limit is automatically enabled whenever the hard heap
-** limit is enabled. ^When sqlite3_hard_heap_limit64(N) is invoked and
-** the soft heap limit is outside the range of 1..N, then the soft heap
-** limit is set to N.  ^Invoking sqlite3_soft_heap_limit64(0) when the
-** hard heap limit is enabled makes the soft heap limit equal to the
-** hard heap limit.
-**
-** The memory allocation limits can also be adjusted using
-** [PRAGMA soft_heap_limit] and [PRAGMA hard_heap_limit].
-**
-** ^(The heap limits are not enforced in the current implementation
-** if one or more of following conditions are true:
-**
-** <ul>
-** <li> The limit value is set to zero.

-** results into the **Outputs** fields.
-**
-** ^(The aConstraint[] array records WHERE clause constraints of the form:

-** <blockquote>column OP expr</blockquote>
-**
-** where OP is =, &lt;, &lt;=, &gt;, or &gt;=.)^  ^(The particular operator is

-** ^(The index of the column is stored in
-** aConstraint[].iColumn.)^  ^(aConstraint[].usable is TRUE if the
-** expr on the right-hand side can be evaluated (and thus the constraint
-** is usable) and false if it cannot.)^
-**
-** ^The optimizer automatically inverts terms of the form "expr OP column"
-** and makes other simplifications to the WHERE clause in an attempt to
-** get as many WHERE clause terms into the form shown above as possible.
-** ^The aConstraint[] array only reports WHERE clause terms that are
-** relevant to the particular virtual table being queried.
-**
-** ^Information about the ORDER BY clause is stored in aOrderBy[].
-** ^Each term of aOrderBy records a column of the ORDER BY clause.
-**
-** The colUsed field indicates which columns of the virtual table may be
-** required by the current scan. Virtual table columns are numbered from
-** zero in the order in which they appear within the CREATE TABLE statement
-** passed to sqlite3_declare_vtab(). For the first 63 columns (columns 0-62),
-** the corresponding bit is set within the colUsed mask if the column may be
-** required by SQLite. If the table has at least 64 columns and any column
-** to the right of the first 63 is required, then bit 63 of colUsed is also
-** set. In other words, column iCol may be required if the expression
-** (colUsed & ((sqlite3_uint64)1 << (iCol>=63 ? 63 : iCol))) evaluates to
-** non-zero.
-**
-** The [xBestIndex] method must fill aConstraintUsage[] with information
-** about what parameters to pass to xFilter.  ^If argvIndex>0 then
-** the right-hand side of the corresponding aConstraint[] is evaluated
-** and becomes the argvIndex-th entry in argv.  ^(If aConstraintUsage[].omit
-** is true, then the constraint is assumed to be fully handled by the
-** virtual table and might not be checked again by the byte code.)^ ^(The
-** aConstraintUsage[].omit flag is an optimization hint. When the omit flag
-** is left in its default setting of false, the constraint will always be
-** checked separately in byte code.  If the omit flag is change to true, then
-** the constraint may or may not be checked in byte code.  In other words,
-** when the omit flag is true there is no guarantee that the constraint will
-** not be checked again using byte code.)^
-**
-** ^The idxNum and idxStr values are recorded and passed into the
-** [xFilter] method.
-** ^[sqlite3_free()] is used to free idxStr if and only if
-** needToFreeIdxStr is true.
-**
-** ^The orderByConsumed means that output from [xFilter]/[xNext] will occur in
-** the correct order to satisfy the ORDER BY clause so that no separate
-** sorting step is required.
-**
-** ^The estimatedCost value is an estimate of the cost of a particular
-** strategy. A cost of N indicates that the cost of the strategy is similar
-** to a linear scan of an SQLite table with N rows. A cost of log(N)
-** indicates that the expense of the operation is similar to that of a
-** binary search on a unique indexed field of an SQLite table with N rows.
-**
-** ^The estimatedRows value is an estimate of the number of rows that
-** will be returned by the strategy.
-**
-** The xBestIndex method may optionally populate the idxFlags field with a
-** mask of SQLITE_INDEX_SCAN_* flags. Currently there is only one such flag -
-** SQLITE_INDEX_SCAN_UNIQUE. If the xBestIndex method sets this flag, SQLite
-** assumes that the strategy may visit at most one row.
-**
-** Additionally, if xBestIndex sets the SQLITE_INDEX_SCAN_UNIQUE flag, then
-** SQLite also assumes that if a call to the xUpdate() method is made as
-** part of the same statement to delete or update a virtual table row and the
-** implementation returns SQLITE_CONSTRAINT, then there is no need to rollback
-** any database changes. In other words, if the xUpdate() returns
-** SQLITE_CONSTRAINT, the database contents must be exactly as they were
-** before xUpdate was called. By contrast, if SQLITE_INDEX_SCAN_UNIQUE is not
-** set and xUpdate returns SQLITE_CONSTRAINT, any database changes made by
-** the xUpdate method are automatically rolled back by SQLite.
-**
-** IMPORTANT: The estimatedRows field was added to the sqlite3_index_info
-** structure for SQLite [version 3.8.2] ([dateof:3.8.2]).
-** If a virtual table extension is
-** used with an SQLite version earlier than 3.8.2, the results of attempting

-** to include crashing the application). The estimatedRows field should

-** a query that uses a [virtual table].

-** ^The first two constants (SQLITE_MUTEX_FAST and SQLITE_MUTEX_RECURSIVE)

-** The mutex implementation does not need to make a distinction
-** between SQLITE_MUTEX_RECURSIVE and SQLITE_MUTEX_FAST if it does
-** not want to.  SQLite will only request a recursive mutex in
-** cases where it really needs one.  If a faster non-recursive mutex
-** implementation is available on the host platform, the mutex subsystem
-** might return such a mutex in response to SQLITE_MUTEX_FAST.
-**
-** ^The other allowed parameters to sqlite3_mutex_alloc() (anything other

-** SQLITE_MUTEX_RECURSIVE.
-**
-** ^Note that if one of the dynamic mutex parameters (SQLITE_MUTEX_FAST
-** or SQLITE_MUTEX_RECURSIVE) is used then sqlite3_mutex_alloc()

-** ^(Some systems (for example, Windows 95) do not support the operation

-** CAPI3REF: Mutex Methods Object
-**
-** An instance of this structure defines the low-level routines
-** used to allocate and use mutexes.
-**
-** Usually, the default mutex implementations provided by SQLite are
-** sufficient, however the application has the option of substituting a custom
-** implementation for specialized deployments or systems for which SQLite
-** does not provide a suitable implementation. In this case, the application
-** creates and populates an instance of this structure to pass
-** to sqlite3_config() along with the [SQLITE_CONFIG_MUTEX] option.
-** Additionally, an instance of this structure can be used as an
-** output variable when querying the system for the current mutex
-** implementation, using the [SQLITE_CONFIG_GETMUTEX] option.
-**
-** ^The xMutexInit method defined by this structure is invoked as
-** part of system initialization by the sqlite3_initialize() function.
-** ^The xMutexInit routine is called by SQLite exactly once for each
-** effective call to [sqlite3_initialize()].
-**
-** ^The xMutexEnd method defined by this structure is invoked as
-** part of system shutdown by the sqlite3_shutdown() function. The
-** implementation of this method is expected to release all outstanding
-** resources obtained by the mutex methods implementation, especially
-** those obtained by the xMutexInit method.  ^The xMutexEnd()
-** interface is invoked exactly once for each call to [sqlite3_shutdown()].
-**
-** ^(The remaining seven methods defined by this structure (xMutexAlloc,
-** xMutexFree, xMutexEnter, xMutexTry, xMutexLeave, xMutexHeld and
-** xMutexNotheld) implement the following interfaces (respectively):
-**
-** <ul>
-**   <li>  [sqlite3_mutex_alloc()] </li>
-**   <li>  [sqlite3_mutex_free()] </li>
-**   <li>  [sqlite3_mutex_enter()] </li>
-**   <li>  [sqlite3_mutex_try()] </li>
-**   <li>  [sqlite3_mutex_leave()] </li>
-**   <li>  [sqlite3_mutex_held()] </li>
-**   <li>  [sqlite3_mutex_notheld()] </li>
-** </ul>)^
-**
-** The only difference is that the public sqlite3_XXX functions enumerated
-** above silently ignore any invocations that pass a NULL pointer instead
-** of a valid mutex handle. The implementations of the methods defined
-** by this structure are not required to handle this case. The results
-** of passing a NULL pointer instead of a valid mutex handle are undefined
-** (i.e. it is acceptable to provide an implementation that segfaults if
-** it is passed a NULL pointer).
-**
-** The xMutexInit() method must be threadsafe.  It must be harmless to
-** invoke xMutexInit() multiple times within the same process and without
-** intervening calls to xMutexEnd().  Second and subsequent calls to
-** xMutexInit() must be no-ops.
-**
-** xMutexInit() must not use SQLite memory allocation ([sqlite3_malloc()]
-** and its associates).  Similarly, xMutexAlloc() must not use SQLite memory
-** allocation for a static mutex.  ^However xMutexAlloc() may use SQLite
-** memory allocation for a fast or recursive mutex.
-**
-** ^SQLite will invoke the xMutexEnd() method when [sqlite3_shutdown()] is
-** called, but only if the prior call to xMutexInit returned SQLITE_OK.
-** If xMutexInit fails in any way, it is expected to clean up after itself
-** prior to returning.

-** The implementation is not required to provide versions of these

-** by enclosing in double-quotes) so as not to confuse the parser.
-**
-** The sqlite3_keyword_count() interface returns the number of distinct
-** keywords understood by SQLite.
-**
-** The sqlite3_keyword_name(N,Z,L) interface finds the 0-based N-th keyword and
-** makes *Z point to that keyword expressed as UTF8 and writes the number
-** of bytes in the keyword into *L.  The string that *Z points to is not
-** zero-terminated.  The sqlite3_keyword_name(N,Z,L) routine returns
-** SQLITE_OK if N is within bounds and SQLITE_ERROR if not. If either Z
-** or L are NULL or invalid pointers then calls to
-** sqlite3_keyword_name(N,Z,L) result in undefined behavior.
-**
-** The sqlite3_keyword_check(Z,L) interface checks to see whether or not
-** the L-byte UTF8 identifier that Z points to is a keyword, returning non-zero
-** if it is and zero if not.
-**
-** The parser used by SQLite is forgiving.  It is often possible to use
-** a keyword as an identifier as long as such use does not result in a
-** parsing ambiguity.  For example, the statement
-** "CREATE TABLE BEGIN(REPLACE,PRAGMA,END);" is accepted by SQLite, and
-** creates a new table named "BEGIN" with three columns named
-** "REPLACE", "PRAGMA", and "END".  Nevertheless, best practice is to avoid
-** using keywords as identifiers.  Common techniques used to avoid keyword
-** name collisions include:
-** <ul>
-** <li> Put all identifier names inside double-quotes.  This is the official
-**      SQL way to escape identifier names.
-** <li> Put identifier names inside &#91;...&#93;.  This is not standard SQL,
-**      but it is what SQL Server does and so lots of programmers use this
-**      technique.
-** <li> Begin every identifier with the letter "Z" as no SQL keywords start
-**      with "Z".
-** <li> Include a digit somewhere in every identifier name.
-** </ul>
-**
-** Note that the number of keywords understood by SQLite can depend on
-** compile-time options.  For example, "VACUUM" is not a keyword if

-**
-** ^(The [sqlite3_config]([SQLITE_CONFIG_PCACHE2], ...) interface can
-** register an alternative page cache implementation by passing in an
-** instance of the sqlite3_pcache_methods2 structure.)^
-** In many applications, most of the heap memory allocated by
-** SQLite is used for the page cache.
-** By implementing a
-** custom page cache using this API, an application can better control
-** the amount of memory consumed by SQLite, the way in which
-** that memory is allocated and released, and the policies used to
-** determine exactly which parts of a database file are cached and for
-** how long.
-**
-** The alternative page cache mechanism is an
-** extreme measure that is only needed by the most demanding applications.
-** The built-in page cache is recommended for most uses.
-**
-** ^(The contents of the sqlite3_pcache_methods2 structure are copied to an
-** internal buffer by SQLite within the call to [sqlite3_config].  Hence
-** the application may discard the parameter after the call to
-** [sqlite3_config()] returns.)^

-** ^(The xInit() method is called once for each effective
-** call to [sqlite3_initialize()])^
-** (usually only once during the lifetime of the process). ^(The xInit()
-** method is passed a copy of the sqlite3_pcache_methods2.pArg value.)^
-** The intent of the xInit() method is to set up global data structures
-** required by the custom page cache implementation.
-** ^(If the xInit() method is NULL, then the
-** built-in default page cache is used instead of the application defined
-** page cache.)^
-**
-** [[the xShutdown() page cache method]]
-** ^The xShutdown() method is called by [sqlite3_shutdown()].
-** It can be used to clean up
-** any outstanding resources before process shutdown, if required.
-** ^The xShutdown() method may be NULL.
-**
-** ^SQLite automatically serializes calls to the xInit method,
-** so the xInit method need not be threadsafe.  ^The
-** xShutdown method is only called from [sqlite3_shutdown()] so it does
-** not need to be threadsafe either.  All other methods must be threadsafe
-** in multithreaded applications.
-**
-** ^SQLite will never invoke xInit() more than once without an intervening
-** call to xShutdown().
-**
-** [[the xCreate() page cache methods]]
-** ^SQLite invokes the xCreate() method to construct a new cache instance.
-** SQLite will typically create one cache instance for each open database file,
-** though this is not guaranteed. ^The
-** first parameter, szPage, is the size in bytes of the pages that must
-** be allocated by the cache.  ^szPage will always a power of two.  ^The
-** second parameter szExtra is a number of bytes of extra storage
-** associated with each page cache entry.  ^The szExtra parameter will
-** a number less than 250.  SQLite will use the
-** extra szExtra bytes on each page to store metadata about the underlying
-** database page on disk.  The value passed into szExtra depends
-** on the SQLite version, the target platform, and how SQLite was compiled.
-** ^The third argument to xCreate(), bPurgeable, is true if the cache being
-** created will be used to cache database pages of a file stored on disk, or
-** false if it is used for an in-memory database. The cache implementation
-** does not have to do anything special based with the value of bPurgeable;
-** it is purely advisory.  ^On a cache where bPurgeable is false, SQLite will
-** never invoke xUnpin() except to deliberately delete a page.
-** ^In other words, calls to xUnpin() on a cache with bPurgeable set to
-** false will always have the "discard" flag set to true.
-** ^Hence, a cache created with bPurgeable false will
-** never contain any unpinned pages.
-**
-** [[the xCachesize() page cache method]]
-** ^(The xCachesize() method may be called at any time by SQLite to set the
-** suggested maximum cache-size (number of pages stored by) the cache
-** instance passed as the first argument. This is the value configured using
-** the SQLite "[PRAGMA cache_size]" command.)^  As with the bPurgeable
-** parameter, the implementation is not required to do anything with this
-** value; it is advisory only.
-**
-** [[the xPagecount() page cache methods]]
-** The xPagecount() method must return the number of pages currently

-**
-** [[the xFetch() page cache methods]]
-** The xFetch() method locates a page in the cache and returns a pointer to
-** an sqlite3_pcache_page object associated with that page, or a NULL pointer.
-** The pBuf element of the returned sqlite3_pcache_page object will be a
-** pointer to a buffer of szPage bytes used to store the content of a
-** single database page.  The pExtra element of sqlite3_pcache_page will be
-** a pointer to the szExtra bytes of extra storage that SQLite has requested
-** for each entry in the page cache.
-**
-** The page to be fetched is determined by the key. ^The minimum key value
-** is 1.  After it has been retrieved using xFetch, the page is considered
-** to be "pinned".
-**
-** If the requested page is already in the page cache, then the page cache
-** implementation must return a pointer to the page buffer with its content
-** intact.  If the requested page is not already in the cache, then the
-** cache implementation should use the value of the createFlag
-** parameter to help it determined what action to take:
-**
-** <table border=1 width=85% align=center>
-** <tr><th> createFlag <th> Behavior when page is not already in cache
-** <tr><td> 0 <td> Do not allocate a new page.  Return NULL.
-** <tr><td> 1 <td> Allocate a new page if it easy and convenient to do so.
-**                 Otherwise return NULL.
-** <tr><td> 2 <td> Make every effort to allocate a new page.  Only return
-**                 NULL if allocating a new page is effectively impossible.

-** not just the specific connection that was passed to sqlite3_backup_init().
-**
-** The [sqlite3_backup] object itself is partially threadsafe. Multiple

-** CAPI3REF: Unlock Notification
-** METHOD: sqlite3
-**
-** ^When running in shared-cache mode, a database operation may fail with
-** an [SQLITE_LOCKED] error if the required locks on the shared-cache or
-** individual tables within the shared-cache cannot be obtained. See
-** [SQLite Shared-Cache Mode] for a description of shared-cache locking.
-** ^This API may be used to register a callback that SQLite will invoke
-** when the connection currently holding the required lock relinquishes it.
-** ^This API is only available if the library was compiled with the
-** [SQLITE_ENABLE_UNLOCK_NOTIFY] C-preprocessor symbol defined.
-**
-** See Also: [Using the SQLite Unlock Notification Feature].
-**
-** ^Shared-cache locks are released when a database connection concludes
-** its current transaction, either by committing it or rolling it back.
-**
-** ^When a connection (known as the blocked connection) fails to obtain a
-** shared-cache lock and SQLITE_LOCKED is returned to the caller, the
-** identity of the database connection (the blocking connection) that
-** has locked the required resource is stored internally. ^After an
-** application receives an SQLITE_LOCKED error, it may call the
-** sqlite3_unlock_notify() method with the blocked connection handle as
-** the first argument to register for a callback that will be invoked
-** when the blocking connections current transaction is concluded. ^The
-** callback is invoked from within the [sqlite3_step] or [sqlite3_close]
-** call that concludes the blocking connection's transaction.
-**
-** ^(If sqlite3_unlock_notify() is called in a multi-threaded application,
-** there is a chance that the blocking connection will have already
-** concluded its transaction by the time sqlite3_unlock_notify() is invoked.
-** If this happens, then the specified callback is invoked immediately,
-** from within the call to sqlite3_unlock_notify().)^
-**
-** ^If the blocked connection is attempting to obtain a write-lock on a
-** shared-cache table, and more than one other connection currently holds
-** a read-lock on the same table, then SQLite arbitrarily selects one of
-** the other connections to use as the blocking connection.
-**
-** ^(There may be at most one unlock-notify callback registered by a
-** blocked connection. If sqlite3_unlock_notify() is called when the
-** blocked connection already has a registered unlock-notify callback,
-** then the new callback replaces the old.)^ ^If sqlite3_unlock_notify() is
-** called with a NULL pointer as its second argument, then any existing
-** unlock-notify callback is canceled. ^The blocked connections
-** unlock-notify callback may also be canceled by closing the blocked
-** connection using [sqlite3_close()].
-**
-** The unlock-notify callback is not reentrant. If an application invokes
-** any sqlite3_xxx API functions from within an unlock-notify callback, a
-** crash or deadlock may be the result.
-**
-** ^Unless deadlock is detected (see below), sqlite3_unlock_notify() always
-** returns SQLITE_OK.
-**
-** <b>Callback Invocation Details</b>
-**
-** When an unlock-notify callback is registered, the application provides a
-** single void* pointer that is passed to the callback when it is invoked.
-** However, the signature of the callback function allows SQLite to pass
-** it an array of void* context pointers. The first argument passed to
-** an unlock-notify callback is a pointer to an array of void* pointers,
-** and the second is the number of entries in the array.
-**
-** When a blocking connection's transaction is concluded, there may be
-** more than one blocked connection that has registered for an unlock-notify
-** callback. ^If two or more such blocked connections have specified the
-** same callback function, then instead of invoking the callback function
-** multiple times, it is invoked once with the set of void* context pointers
-** specified by the blocked connections bundled together into an array.
-** This gives the application an opportunity to prioritize any actions
-** related to the set of unblocked database connections.
-**
-** <b>Deadlock Detection</b>
-**
-** Assuming that after registering for an unlock-notify callback a
-** database waits for the callback to be issued before taking any further
-** action (a reasonable assumption), then using this API may cause the
-** application to deadlock. For example, if connection X is waiting for
-** connection Y's transaction to be concluded, and similarly connection
-** Y is waiting on connection X's transaction, then neither connection
-** will proceed and the system may remain deadlocked indefinitely.
-**
-** To avoid this scenario, the sqlite3_unlock_notify() performs deadlock
-** detection. ^If a given call to sqlite3_unlock_notify() would put the
-** system in a deadlocked state, then SQLITE_LOCKED is returned and no
-** unlock-notify callback is registered. The system is said to be in
-** a deadlocked state if connection A has registered for an unlock-notify
-** callback on the conclusion of connection B's transaction, and connection
-** B has itself registered for an unlock-notify callback when connection
-** A's transaction is concluded. ^Indirect deadlock is also detected, so
-** the system is also considered to be deadlocked if connection B has
-** registered for an unlock-notify callback on the conclusion of connection
-** C's transaction, where connection C is waiting on connection A. ^Any
-** number of levels of indirection are allowed.
-**
-** <b>The "DROP TABLE" Exception</b>
-**
-** When a call to [sqlite3_step()] returns SQLITE_LOCKED, it is almost
-** always appropriate to call sqlite3_unlock_notify(). There is however,
-** one exception. When executing a "DROP TABLE" or "DROP INDEX" statement,
-** SQLite checks if there are any currently executing SELECT statements
-** that belong to the same connection. If there are, SQLITE_LOCKED is
-** returned. In this case there is no "blocking connection", so invoking
-** sqlite3_unlock_notify() results in the unlock-notify callback being
-** invoked immediately. If the application then re-attempts the "DROP TABLE"
-** or "DROP INDEX" query, an infinite loop might be the result.
-**
-** One way around this problem is to check the extended error code returned
-** by an sqlite3_step() call. ^(If there is a blocking connection, then the
-** extended error code is set to SQLITE_LOCKED_SHAREDCACHE. Otherwise, in
-** the special "DROP TABLE/INDEX" case, the extended error code is just
-** SQLITE_LOCKED.)^

-** the return value from sqlite3_vtab_in(P,N,F) will always be the same
-** within the same xBestIndex call.  ^If the interface returns true
-** (non-zero), that means that the constraint is an IN operator
-** that can be processed all-at-once.  ^If the constraint is not an IN
-** operator or cannot be processed all-at-once, then the interface returns

-**  &nbsp;     CREATE TABLE sqlite_stat1(tbl,idx,stat)
-**  </pre>
-**
-** Even though sqlite_stat1 does not have a PRIMARY KEY, changes are
-** recorded for it as if the PRIMARY KEY is (tbl,idx). Additionally, changes
-** are recorded for rows for which (idx IS NULL) is true. However, for such
-** rows a zero-length blob (SQL value X'') is stored in the changeset or
-** patchset instead of a NULL value. This allows such changesets to be
-** manipulated by legacy implementations of sqlite3changeset_invert(),
-** concat() and similar.
-**
-** The sqlite3changeset_apply() function automatically converts the
-** zero-length blob back to a NULL value when updating the sqlite_stat1
-** table. However, if the application calls sqlite3changeset_new(),
-** sqlite3changeset_old() or sqlite3changeset_conflict on a changeset
-** iterator directly (including on a changeset iterator passed to a
-** conflict-handler callback) then the X'' value is returned. The application
-** must translate X'' to NULL itself if required.
-**
-** Legacy (older than 3.22.0) versions of the sessions module cannot capture
-** changes made to the sqlite_stat1 table. Legacy versions of the
-** sqlite3changeset_apply() function silently ignore any modifications to the
-** sqlite_stat1 table that are part of a changeset or patchset.

-** CAPI3REF: Generate A Changeset From A Session Object
-** METHOD: sqlite3_session
-**
-** Obtain a changeset containing changes to the tables attached to the
-** session object passed as the first argument. If successful,
-** set *ppChangeset to point to a buffer containing the changeset
-** and *pnChangeset to the size of the changeset in bytes before returning
-** SQLITE_OK. If an error occurs, set both *ppChangeset and *pnChangeset to
-** zero and return an SQLite error code.
-**
-** A changeset consists of zero or more INSERT, UPDATE and/or DELETE changes,
-** each representing a change to a single row of an attached table. An INSERT
-** change contains the values of each field of a new database row. A DELETE
-** contains the original values of each field of a deleted database row. An
-** UPDATE change contains the original values of each field of an updated
-** database row along with the updated values for each updated non-primary-key
-** column. It is not possible for an UPDATE change to represent a change that
-** modifies the values of primary key columns. If such a change is made, it
-** is represented in a changeset as a DELETE followed by an INSERT.
-**
-** Changes are not recorded for rows that have NULL values stored in one or
-** more of their PRIMARY KEY columns. If such a row is inserted or deleted,
-** no corresponding change is present in the changesets returned by this
-** function. If an existing row with one or more NULL values stored in
-** PRIMARY KEY columns is updated so that all PRIMARY KEY columns are non-NULL,
-** only an INSERT is appears in the changeset. Similarly, if an existing row
-** with non-NULL PRIMARY KEY values is updated so that one or more of its
-** PRIMARY KEY columns are set to NULL, the resulting changeset contains a
-** DELETE change only.
-**
-** The contents of a changeset may be traversed using an iterator created
-** using the [sqlite3changeset_start()] API. A changeset may be applied to
-** a database with a compatible schema using the [sqlite3changeset_apply()]
-** API.
-**
-** Within a changeset generated by this function, all changes related to a
-** single table are grouped together. In other words, when iterating through
-** a changeset or when applying a changeset to a database, all changes related
-** to a single table are processed before moving on to the next table. Tables
-** are sorted in the same order in which they were attached (or auto-attached)
-** to the sqlite3_session object. The order in which the changes related to
-** a single table are stored is undefined.
-**
-** Following a successful call to this function, it is the responsibility of
-** the caller to eventually free the buffer that *ppChangeset points to using
-** [sqlite3_free()].
-**
-** <h3>Changeset Generation</h3>
-**
-** Once a table has been attached to a session object, the session object
-** records the primary key values of all new rows inserted into the table.
-** It also records the original primary key and other column values of any
-** deleted or updated rows. For each unique primary key value, data is only
-** recorded once - the first time a row with said primary key is inserted,
-** updated or deleted in the lifetime of the session.
-**
-** There is one exception to the previous paragraph: when a row is inserted,
-** updated or deleted, if one or more of its primary key columns contain a
-** NULL value, no record of the change is made.
-**
-** The session object therefore accumulates two types of records - those
-** that consist of primary key values only (created when the user inserts
-** a new record) and those that consist of the primary key values and the
-** original values of other table columns (created when the users deletes
-** or updates a record).
-**
-** When this function is called, the requested changeset is created using
-** both the accumulated records and the current contents of the database
-** file. Specifically:
-**
-** <ul>
-**   <li> For each record generated by an insert, the database is queried
-**        for a row with a matching primary key. If one is found, an INSERT
-**        change is added to the changeset. If no such row is found, no change
-**        is added to the changeset.
-**
-**   <li> For each record generated by an update or delete, the database is
-**        queried for a row with a matching primary key. If such a row is
-**        found and one or more of the non-primary key fields have been
-**        modified from their original values, an UPDATE change is added to
-**        the changeset. Or, if no such row is found in the table, a DELETE
-**        change is added to the changeset. If there is a row with a matching
-**        primary key in the database, but all fields contain their original
-**        values, no change is added to the changeset.
-** </ul>
-**
-** This means, amongst other things, that if a row is inserted and then later
-** deleted while a session object is active, neither the insert nor the delete
-** will be present in the changeset. Or if a row is deleted and then later a
-** row with the same primary key values inserted while a session object is
-** active, the resulting changeset will contain an UPDATE change instead of
-** a DELETE and an INSERT.
-**
-** When a session object is disabled (see the [sqlite3session_enable()] API),
-** it does not accumulate records when rows are inserted, updated or deleted.
-** This may appear to have some counter-intuitive effects if a single row
-** is written to more than once during a session. For example, if a row
-** is inserted while a session object is enabled, then later deleted while
-** the same session object is disabled, no INSERT record will appear in the
-** changeset, even though the delete took place while the session was disabled.
-** Or, if one field of a row is updated while a session is disabled, and
-** another field of the same row is updated while the session is enabled, the
-** resulting changeset will contain an UPDATE change that updates both fields.

-** used to update the table in database zFrom (call this the "from-table")
-** so that its content is the same as the table attached to the session
-** object (call this the "to-table"). Specifically:

-**   <li> For each row (primary key) that exists in both tables, but features

-**
-** The fourth argument (xFilter) passed to these functions is the "filter

-** change in the changeset, the filter callback is invoked with
-** the table name as the second argument, and a copy of the context pointer
-** passed as the sixth argument as the first. If the "filter callback"
-** returns zero, then no attempt is made to apply any changes to the table.
-** Otherwise, if the return value is non-zero or the xFilter argument to
-** is NULL, all changes related to the table are attempted.
-**
-** For each table that is not excluded by the filter callback, this function
-** tests that the target database contains a compatible table. A table is
-** considered compatible if all of the following are true:
-**
-** <ul>
-**   <li> The table has the same name as the name recorded in the
-**        changeset, and
-**   <li> The table has at least as many columns as recorded in the
-**        changeset, and
-**   <li> The table has primary key columns in the same position as
-**        recorded in the changeset.
-** </ul>
-**
-** If there is no compatible table, it is not an error, but none of the
-** changes associated with the table are applied. A warning message is issued
-** via the sqlite3_log() mechanism with the error code SQLITE_SCHEMA. At most
-** one such warning is issued for each table in the changeset.
-**
-** For each change for which there is a compatible table, an attempt is made
-** to modify the table contents according to the UPDATE, INSERT or DELETE
-** change. If a change cannot be applied cleanly, the conflict handler
-** function passed as the fifth argument to sqlite3changeset_apply() may be
-** invoked. A description of exactly when the conflict handler is invoked for
-** each type of change is below.
-**
-** Unlike the xFilter argument, xConflict may not be passed NULL. The results
-** of passing anything other than a valid function pointer as the xConflict
-** argument are undefined.

-** Each time the conflict handler function is invoked, it must return one

-** if the second argument passed to the conflict handler is either
-** SQLITE_CHANGESET_DATA or SQLITE_CHANGESET_CONFLICT. If the conflict-handler
-** returns an illegal value, any changes already made are rolled back and

-** the documentation for the three
-** [SQLITE_CHANGESET_OMIT|available return values] for details.

-** <dt>DELETE Changes<dd>

-**   stored in all non-primary key columns also match the values stored in
-**   the changeset the row is deleted from the target database.
-**
-**   If a row with matching primary key values is found, but one or more of
-**   the non-primary key fields contains a value different from the original
-**   row value stored in the changeset, the conflict-handler function is
-**   invoked with [SQLITE_CHANGESET_DATA] as the second argument. If the

-**   the current database contents - any trailing database table columns
-**   are ignored.
-**
-**   If no row with matching primary key values is found in the database,
-**   the conflict-handler function is invoked with [SQLITE_CHANGESET_NOTFOUND]
-**   passed as the second argument.
-**
-**   If the DELETE operation is attempted, but SQLite returns SQLITE_CONSTRAINT
-**   (which can only happen if a foreign key constraint is violated), the
-**   conflict-handler function is invoked with [SQLITE_CHANGESET_CONSTRAINT]
-**   passed as the second argument. This includes the case where the DELETE
-**   operation is attempted because an earlier call to the conflict handler
-**   function returned [SQLITE_CHANGESET_REPLACE].

-** <dt>INSERT Changes<dd>
-**   For each INSERT change, an attempt is made to insert the new row into

-**   values.
-**
-**   If the attempt to insert the row fails because the database already
-**   contains a row with the same primary key values, the conflict handler
-**   function is invoked with the second argument set to
-**   [SQLITE_CHANGESET_CONFLICT].
-**
-**   If the attempt to insert the row fails because of some other constraint
-**   violation (e.g. NOT NULL or UNIQUE), the conflict handler function is
-**   invoked with the second argument set to [SQLITE_CHANGESET_CONSTRAINT].

-**   an earlier call to the conflict handler function returned
-**   [SQLITE_CHANGESET_REPLACE].

-** <dt>UPDATE Changes<dd>
-**   For each UPDATE change, the function checks if the target database
-**   contains a row with the same primary key value (or values) as the

-**   the modified non-primary key fields contains a value different from an
-**   original row value stored in the changeset, the conflict-handler function
-**   is invoked with [SQLITE_CHANGESET_DATA] as the second argument. Since
-**   UPDATE changes only contain values for non-primary key fields that are
-**   to be modified, only those fields need to match the original values to
-**   avoid the SQLITE_CHANGESET_DATA conflict-handler callback.
-**
-**   If no row with matching primary key values is found in the database,

-**   passed as the second argument.

-** CAPI3REF: Rebasing changesets
-** EXPERIMENTAL
-**
-** Suppose there is a site hosting a database in state S0. And that
-** modifications are made that move that database to state S1 and a
-** changeset recorded (the "local" changeset). Then, a changeset based
-** on S0 is received from another site (the "remote" changeset) and
-** applied to the database. The database is then in state
-** (S1+"remote"), where the exact state depends on any conflict
-** resolution decisions (OMIT or REPLACE) made while applying "remote".
-** Rebasing a changeset is to update it to take those conflict
-** resolution decisions into account, so that the same conflicts
-** do not have to be resolved elsewhere in the network.
-**
-** For example, if both the local and remote changesets contain an
-** INSERT of the same key on "CREATE TABLE t1(a PRIMARY KEY, b)":
-**
-**   local:  INSERT INTO t1 VALUES(1, 'v1');
-**   remote: INSERT INTO t1 VALUES(1, 'v2');
-**
-** and the conflict resolution is REPLACE, then the INSERT change is
-** removed from the local changeset (it was overridden). Or, if the
-** conflict resolution was "OMIT", then the local changeset is modified
-** to instead contain:
-**
-**           UPDATE t1 SET b = 'v2' WHERE a=1;
-**
-** Changes within the local changeset are rebased as follows:
-**
-** <dl>
-** <dt>Local INSERT<dd>
-**   This may only conflict with a remote INSERT. If the conflict
-**   resolution was OMIT, then add an UPDATE change to the rebased
-**   changeset. Or, if the conflict resolution was REPLACE, add
-**   nothing to the rebased changeset.
-**
-** <dt>Local DELETE<dd>
-**   This may conflict with a remote UPDATE or DELETE. In both cases the
-**   only possible resolution is OMIT. If the remote operation was a
-**   DELETE, then add no change to the rebased changeset. If the remote
-**   operation was an UPDATE, then the old.* fields of change are updated
-**   to reflect the new.* values in the UPDATE.
-**
-** <dt>Local UPDATE<dd>
-**   This may conflict with a remote UPDATE or DELETE. If it conflicts
-**   with a DELETE, and the conflict resolution was OMIT, then the update
-**   is changed into an INSERT. Any undefined values in the new.* record
-**   from the update change are filled in using the old.* values from
-**   the conflicting DELETE. Or, if the conflict resolution was REPLACE,
-**   the UPDATE change is simply omitted from the rebased changeset.
-**
-**   If conflict is with a remote UPDATE and the resolution is OMIT, then
-**   the old.* values are rebased using the new.* values in the remote
-**   change. Or, if the resolution is REPLACE, then the change is copied
-**   into the rebased changeset with updates to columns also updated by
-**   the conflicting remote UPDATE removed. If this means no columns would
-**   be updated, the change is omitted.
-** </dl>
-**
-** A local change may be rebased against multiple remote changes
-** simultaneously. If a single key is modified by multiple remote
-** changesets, they are combined as follows before the local changeset
-** is rebased:
-**
-** <ul>
-**    <li> If there has been one or more REPLACE resolutions on a
-**         key, it is rebased according to a REPLACE.
-**
-**    <li> If there have been no REPLACE resolutions on a key, then
-**         the local changeset is rebased according to the most recent
-**         of the OMIT resolutions.
-** </ul>
-**
-** Note that conflict resolutions from multiple remote changesets are
-** combined on a per-field basis, not per-row. This means that in the
-** case of multiple remote UPDATE operations, some fields of a single
-** local change may be rebased for REPLACE while others are rebased for
-** OMIT.
-**
-** In order to rebase a local changeset, the remote changeset must first
-** be applied to the local database using sqlite3changeset_apply_v2() and
-** the buffer of rebase information captured. Then:
-**
-** <ol>
-**   <li> An sqlite3_rebaser object is created by calling
-**        sqlite3rebaser_create().
-**   <li> The new object is configured with the rebase buffer obtained from
-**        sqlite3changeset_apply_v2() by calling sqlite3rebaser_configure().
-**        If the local changeset is to be rebased against multiple remote
-**        changesets, then sqlite3rebaser_configure() should be called
-**        multiple times, in the same order that the multiple
-**        sqlite3changeset_apply_v2() calls were made.
-**   <li> Each local changeset is rebased by calling sqlite3rebaser_rebase().

-**   <tr><th>Streaming function<th>Non-streaming equivalent</th>

-**   <tr><td>sqlite3session_changeset_strm<td>[sqlite3session_changeset]
-**   <tr><td>sqlite3session_patchset_strm<td>[sqlite3session_patchset]
-** </table>
-**
-** Non-streaming functions that accept changesets (or patchsets) as input
-** require that the entire changeset be stored in a single buffer in memory.
-** Similarly, those that return a changeset or patchset do so by returning
-** a pointer to a single large buffer allocated using sqlite3_malloc().
-** Normally this is convenient. However, if an application running in a
-** low-memory environment is required to handle very large changesets, the
-** large contiguous memory allocations required can become onerous.
-**
-** In order to avoid this problem, instead of a single large buffer, input
-** is passed to a streaming API functions by way of a callback function that
-** the sessions module invokes to incrementally request input data as it is
-** required. In all cases, a pair of API function parameters such as
-**
-**  <pre>
-**  &nbsp;     int nChangeset,
-**  &nbsp;     void *pChangeset,
-**  </pre>
-**
-** Is replaced by:
-**
-**  <pre>
-**  &nbsp;     int (*xInput)(void *pIn, void *pData, int *pnData),
-**  &nbsp;     void *pIn,
-**  </pre>
-**
-** Each time the xInput callback is invoked by the sessions module, the first
-** argument passed is a copy of the supplied pIn context pointer. The second
-** argument, pData, points to a buffer (*pnData) bytes in size. Assuming no
-** error occurs the xInput method should copy up to (*pnData) bytes of data
-** into the buffer and set (*pnData) to the actual number of bytes copied
-** before returning SQLITE_OK. If the input is completely exhausted, (*pnData)
-** should be set to zero to indicate this. Or, if an error occurs, an SQLite
-** error code should be returned. In all cases, if an xInput callback returns
-** an error, all processing is abandoned and the streaming API function
-** returns a copy of the error code to the caller.
-**
-** In the case of sqlite3changeset_start_strm(), the xInput callback may be
-** invoked by the sessions module at any point during the lifetime of the
-** iterator. If such an xInput callback returns an error, the iterator enters
-** an error state, whereby all subsequent calls to iterator functions
-** immediately fail with the same error code as returned by xInput.
-**
-** Similarly, streaming API functions that return changesets (or patchsets)
-** return them in chunks by way of a callback function instead of via a
-** pointer to a single large buffer. In this case, a pair of parameters such
-** as:
-**
-**  <pre>
-**  &nbsp;     int *pnChangeset,
-**  &nbsp;     void **ppChangeset,
-**  </pre>
-**
-** Is replaced by:
-**
-**  <pre>
-**  &nbsp;     int (*xOutput)(void *pOut, const void *pData, int nData),
-**  &nbsp;     void *pOut
-**  </pre>
-**
-** The xOutput callback is invoked zero or more times to return data to
-** the application. The first parameter passed to each call is a copy of the
-** pOut pointer supplied by the application. The second parameter, pData,
-** points to a buffer nData bytes in size containing the chunk of output
-** data being returned. If the xOutput callback successfully processes the
-** supplied data, it should return SQLITE_OK to indicate success. Otherwise,
-** it should return some other SQLite error code. In this case processing
-** is immediately abandoned and the streaming API function returns a copy
-** of the xOutput error code to the application.
-**
-** The sessions module never invokes an xOutput callback with the third
-** parameter set to a value less than or equal to zero. Other than this,
-** no guarantees are made as to the size of the chunks of data returned.

-**   the total number of tokens in column iCol, considering all rows in
-**   the FTS5 table.
-**
-**   If parameter iCol is greater than or equal to the number of columns
-**   in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
-**   an OOM condition or IO error), an appropriate SQLite error code is
-**   returned.
-**
-** xColumnCount(pFts):
-**   Return the number of columns in the table.
-**
-** xColumnSize(pFts, iCol, pnToken):
-**   If parameter iCol is less than zero, set output variable *pnToken
-**   to the total number of tokens in the current row. Or, if iCol is
-**   non-negative but less than the number of columns in the table, set
-**   *pnToken to the number of tokens in column iCol of the current row.
-**
-**   If parameter iCol is greater than or equal to the number of columns
-**   in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
-**   an OOM condition or IO error), an appropriate SQLite error code is
-**   returned.
-**
-**   This function may be quite inefficient if used with an FTS5 table
-**   created with the "columnsize=0" option.
-**
-** xColumnText:
-**   If parameter iCol is less than zero, or greater than or equal to the
-**   number of columns in the table, SQLITE_RANGE is returned.
-**
-**   Otherwise, this function attempts to retrieve the text of column iCol of
-**   the current document. If successful, (*pz) is set to point to a buffer
-**   containing the text in utf-8 encoding, (*pn) is set to the size in bytes
-**   (not characters) of the buffer and SQLITE_OK is returned. Otherwise,
-**   if an error occurs, an SQLite error code is returned and the final values
-**   of (*pz) and (*pn) are undefined.
-**
-** xPhraseCount:
-**   Returns the number of phrases in the current query expression.
-**
-** xPhraseSize:
-**   If parameter iCol is less than zero, or greater than or equal to the
-**   number of phrases in the current query, as returned by xPhraseCount,
-**   0 is returned. Otherwise, this function returns the number of tokens in
-**   phrase iPhrase of the query. Phrases are numbered starting from zero.
-**
-** xInstCount:
-**   Set *pnInst to the total number of occurrences of all phrases within
-**   the query within the current row. Return SQLITE_OK if successful, or
-**   an error code (i.e. SQLITE_NOMEM) if an error occurs.
-**
-**   This API can be quite slow if used with an FTS5 table created with the
-**   "detail=none" or "detail=column" option. If the FTS5 table is created
-**   with either "detail=none" or "detail=column" and "content=" option
-**   (i.e. if it is a contentless table), then this API always returns 0.
-**
-** xInst:
-**   Query for the details of phrase match iIdx within the current row.
-**   Phrase matches are numbered starting from zero, so the iIdx argument
-**   should be greater than or equal to zero and smaller than the value
-**   output by xInstCount(). If iIdx is less than zero or greater than
-**   or equal to the value returned by xInstCount(), SQLITE_RANGE is returned.
-**
-**   Otherwise, output parameter *piPhrase is set to the phrase number, *piCol
-**   to the column in which it occurs and *piOff the token offset of the
-**   first token of the phrase. SQLITE_OK is returned if successful, or an
-**   error code (i.e. SQLITE_NOMEM) if an error occurs.
-**
-**   This API can be quite slow if used with an FTS5 table created with the
-**   "detail=none" or "detail=column" option.
-**
-** xRowid:
-**   Returns the rowid of the current row.
-**
-** xTokenize:
-**   Tokenize text using the tokenizer belonging to the FTS5 table.
-**
-** xQueryPhrase(pFts5, iPhrase, pUserData, xCallback):
-**   This API function is used to query the FTS table for phrase iPhrase
-**   of the current query. Specifically, a query equivalent to:
-**
-**       ... FROM ftstable WHERE ftstable MATCH $p ORDER BY rowid
-**
-**   with $p set to a phrase equivalent to the phrase iPhrase of the
-**   current query is executed. Any column filter that applies to
-**   phrase iPhrase of the current query is included in $p. For each
-**   row visited, the callback function passed as the fourth argument
-**   is invoked. The context and API objects passed to the callback
-**   function may be used to access the properties of each matched row.
-**   Invoking Api.xUserData() returns a copy of the pointer passed as
-**   the third argument to pUserData.
-**
-**   If parameter iPhrase is less than zero, or greater than or equal to
-**   the number of phrases in the query, as returned by xPhraseCount(),
-**   this function returns SQLITE_RANGE.
-**
-**   If the callback function returns any value other than SQLITE_OK, the
-**   query is abandoned and the xQueryPhrase function returns immediately.
-**   If the returned value is SQLITE_DONE, xQueryPhrase returns SQLITE_OK.
-**   Otherwise, the error code is propagated upwards.
-**
-**   If the query runs to completion without incident, SQLITE_OK is returned.
-**   Or, if some error occurs before the query completes or is aborted by
-**   the callback, an SQLite error code is returned.
-**
-**
-** xSetAuxdata(pFts5, pAux, xDelete)
-**
-**   Save the pointer passed as the second argument as the extension function's
-**   "auxiliary data". The pointer may then be retrieved by the current or any
-**   future invocation of the same fts5 extension function made as part of
-**   the same MATCH query using the xGetAuxdata() API.
-**
-**   Each extension function is allocated a single auxiliary data slot for
-**   each FTS query (MATCH expression). If the extension function is invoked
-**   more than once for a single FTS query, then all invocations share a
-**   single auxiliary data context.
-**
-**   If there is already an auxiliary data pointer when this function is
-**   invoked, then it is replaced by the new pointer. If an xDelete callback
-**   was specified along with the original pointer, it is invoked at this
-**   point.
-**
-**   The xDelete callback, if one is specified, is also invoked on the
-**   auxiliary data pointer after the FTS5 query has finished.
-**
-**   If an error (e.g. an OOM condition) occurs within this function,
-**   the auxiliary data is set to NULL and an error code returned. If the
-**   xDelete parameter was not NULL, it is invoked on the auxiliary data
-**   pointer before returning.
-**
-**
-** xGetAuxdata(pFts5, bClear)
-**
-**   Returns the current auxiliary data pointer for the fts5 extension
-**   function. See the xSetAuxdata() method for details.
-**
-**   If the bClear argument is non-zero, then the auxiliary data is cleared
-**   (set to NULL) before this function returns. In this case the xDelete,
-**   if any, is not invoked.
-**
-**
-** xRowCount(pFts5, pnRow)
-**
-**   This function is used to retrieve the total number of rows in the table.
-**   In other words, the same value that would be returned by:
-**
-**        SELECT count(*) FROM ftstable;
-**
-** xPhraseFirst()
-**   This function is used, along with type Fts5PhraseIter and the xPhraseNext
-**   method, to iterate through all instances of a single query phrase within
-**   the current row. This is the same information as is accessible via the
-**   xInstCount/xInst APIs. While the xInstCount/xInst APIs are more convenient
-**   to use, this API may be faster under some circumstances. To iterate
-**   through instances of phrase iPhrase, use the following code:
-**
-**       Fts5PhraseIter iter;
-**       int iCol, iOff;
-**       for(pApi->xPhraseFirst(pFts, iPhrase, &iter, &iCol, &iOff);
-**           iCol>=0;
-**           pApi->xPhraseNext(pFts, &iter, &iCol, &iOff)
-**       ){
-**         // An instance of phrase iPhrase at offset iOff of column iCol
-**       }
-**
-**   The Fts5PhraseIter structure is defined above. Applications should not
-**   modify this structure directly - it should only be used as shown above
-**   with the xPhraseFirst() and xPhraseNext() API methods (and by
-**   xPhraseFirstColumn() and xPhraseNextColumn() as illustrated below).
-**
-**   This API can be quite slow if used with an FTS5 table created with the
-**   "detail=none" or "detail=column" option. If the FTS5 table is created
-**   with either "detail=none" or "detail=column" and "content=" option
-**   (i.e. if it is a contentless table), then this API always iterates
-**   through an empty set (all calls to xPhraseFirst() set iCol to -1).
-**
-** xPhraseNext()
-**   See xPhraseFirst above.
-**
-** xPhraseFirstColumn()
-**   This function and xPhraseNextColumn() are similar to the xPhraseFirst()
-**   and xPhraseNext() APIs described above. The difference is that instead
-**   of iterating through all instances of a phrase in the current row, these
-**   APIs are used to iterate through the set of columns in the current row
-**   that contain one or more instances of a specified phrase. For example:
-**
-**       Fts5PhraseIter iter;
-**       int iCol;
-**       for(pApi->xPhraseFirstColumn(pFts, iPhrase, &iter, &iCol);
-**           iCol>=0;
-**           pApi->xPhraseNextColumn(pFts, &iter, &iCol)
-**       ){
-**         // Column iCol contains at least one instance of phrase iPhrase
-**       }
-**
-**   This API can be quite slow if used with an FTS5 table created with the
-**   "detail=none" option. If the FTS5 table is created with either
-**   "detail=none" "content=" option (i.e. if it is a contentless table),
-**   then this API always iterates through an empty set (all calls to
-**   xPhraseFirstColumn() set iCol to -1).
-**
-**   The information accessed using this API and its companion
-**   xPhraseFirstColumn() may also be obtained using xPhraseFirst/xPhraseNext
-**   (or xInst/xInstCount). The chief advantage of this API is that it is
-**   significantly more efficient than those alternatives when used with
-**   "detail=column" tables.
-**
-** xPhraseNextColumn()
-**   See xPhraseFirstColumn above.
-**
-** xQueryToken(pFts5, iPhrase, iToken, ppToken, pnToken)
-**   This is used to access token iToken of phrase iPhrase of the current
-**   query. Before returning, output parameter *ppToken is set to point
-**   to a buffer containing the requested token, and *pnToken to the
-**   size of this buffer in bytes.
-**
-**   If iPhrase or iToken are less than zero, or if iPhrase is greater than
-**   or equal to the number of phrases in the query as reported by
-**   xPhraseCount(), or if iToken is equal to or greater than the number of
-**   tokens in the phrase, SQLITE_RANGE is returned and *ppToken and *pnToken
-     are both zeroed.
-**
-**   The output text is not a copy of the query text that specified the
-**   token. It is the output of the tokenizer module. For tokendata=1
-**   tables, this includes any embedded 0x00 and trailing data.
-**
-** xInstToken(pFts5, iIdx, iToken, ppToken, pnToken)
-**   This is used to access token iToken of phrase hit iIdx within the
-**   current row. If iIdx is less than zero or greater than or equal to the
-**   value returned by xInstCount(), SQLITE_RANGE is returned.  Otherwise,
-**   output variable (*ppToken) is set to point to a buffer containing the
-**   matching document token, and (*pnToken) to the size of that buffer in
-**   bytes. This API is not available if the specified token matches a
-**   prefix query term. In that case both output variables are always set
-**   to 0.
-**
-**   The output text is not a copy of the document text that was tokenized.
-**   It is the output of the tokenizer module. For tokendata=1 tables, this
-**   includes any embedded 0x00 and trailing data.
-**
-**   This API can be quite slow if used with an FTS5 table created with the
-**   "detail=none" or "detail=column" option.

-** CUSTOM AUXILIARY FUNCTIONS
-*************************************************************************/
-
-/*************************************************************************
-** CUSTOM TOKENIZERS
-**
-** Applications may also register custom tokenizer types. A tokenizer
-** is registered by providing fts5 with a populated instance of the
-** following structure. All structure methods must be defined, setting
-** any member of the fts5_tokenizer struct to NULL leads to undefined
-** behaviour. The structure methods are expected to function as follows:
-**
-** xCreate:
-**   This function is used to allocate and initialize a tokenizer instance.
-**   A tokenizer instance is required to actually tokenize text.
-**
-**   The first argument passed to this function is a copy of the (void*)
-**   pointer provided by the application when the fts5_tokenizer object
-**   was registered with FTS5 (the third argument to xCreateTokenizer()).
-**   The second and third arguments are an array of nul-terminated strings
-**   containing the tokenizer arguments, if any, specified following the
-**   tokenizer name as part of the CREATE VIRTUAL TABLE statement used
-**   to create the FTS5 table.
-**
-**   The final argument is an output variable. If successful, (*ppOut)
-**   should be set to point to the new tokenizer handle and SQLITE_OK
-**   returned. If an error occurs, some value other than SQLITE_OK should
-**   be returned. In this case, fts5 assumes that the final value of *ppOut
-**   is undefined.
-**
-** xDelete:
-**   This function is invoked to delete a tokenizer handle previously
-**   allocated using xCreate(). Fts5 guarantees that this function will
-**   be invoked exactly once for each successful call to xCreate().
-**
-** xTokenize:
-**   This function is expected to tokenize the nText byte string indicated
-**   by argument pText. pText may or may not be nul-terminated. The first
-**   argument passed to this function is a pointer to an Fts5Tokenizer object
-**   returned by an earlier call to xCreate().
-**
-**   The second argument indicates the reason that FTS5 is requesting
-**   tokenization of the supplied text. This is always one of the following
-**   four values:
-**
-**   <ul><li> <b>FTS5_TOKENIZE_DOCUMENT</b> - A document is being inserted into
-**            or removed from the FTS table. The tokenizer is being invoked to
-**            determine the set of tokens to add to (or delete from) the
-**            FTS index.
-**
-**       <li> <b>FTS5_TOKENIZE_QUERY</b> - A MATCH query is being executed
-**            against the FTS index. The tokenizer is being called to tokenize
-**            a bareword or quoted string specified as part of the query.
-**
-**       <li> <b>(FTS5_TOKENIZE_QUERY | FTS5_TOKENIZE_PREFIX)</b> - Same as
-**            FTS5_TOKENIZE_QUERY, except that the bareword or quoted string is
-**            followed by a "*" character, indicating that the last token
-**            returned by the tokenizer will be treated as a token prefix.
-**
-**       <li> <b>FTS5_TOKENIZE_AUX</b> - The tokenizer is being invoked to
-**            satisfy an fts5_api.xTokenize() request made by an auxiliary
-**            function. Or an fts5_api.xColumnSize() request made by the same
-**            on a columnsize=0 database.
-**   </ul>
-**
-**   For each token in the input string, the supplied callback xToken() must
-**   be invoked. The first argument to it should be a copy of the pointer
-**   passed as the second argument to xTokenize(). The third and fourth
-**   arguments are a pointer to a buffer containing the token text, and the
-**   size of the token in bytes. The 4th and 5th arguments are the byte offsets
-**   of the first byte of and first byte immediately following the text from
-**   which the token is derived within the input.
-**
-**   The second argument passed to the xToken() callback ("tflags") should
-**   normally be set to 0. The exception is if the tokenizer supports
-**   synonyms. In this case see the discussion below for details.
-**
-**   FTS5 assumes the xToken() callback is invoked for each token in the
-**   order that they occur within the input text.
-**
-**   If an xToken() callback returns any value other than SQLITE_OK, then
-**   the tokenization should be abandoned and the xTokenize() method should
-**   immediately return a copy of the xToken() return value. Or, if the
-**   input buffer is exhausted, xTokenize() should return SQLITE_OK. Finally,
-**   if an error occurs with the xTokenize() implementation itself, it
-**   may abandon the tokenization and return any error code other than
-**   SQLITE_OK or SQLITE_DONE.
-**
-** SYNONYM SUPPORT
-**
-**   Custom tokenizers may also support synonyms. Consider a case in which a
-**   user wishes to query for a phrase such as "first place". Using the
-**   built-in tokenizers, the FTS5 query 'first + place' will match instances
-**   of "first place" within the document set, but not alternative forms
-**   such as "1st place". In some applications, it would be better to match
-**   all instances of "first place" or "1st place" regardless of which form
-**   the user specified in the MATCH query text.
-**
-**   There are several ways to approach this in FTS5:
-**
-**   <ol><li> By mapping all synonyms to a single token. In this case, using
-**            the above example, this means that the tokenizer returns the
-**            same token for inputs "first" and "1st". Say that token is in
-**            fact "first", so that when the user inserts the document "I won
-**            1st place" entries are added to the index for tokens "i", "won",
-**            "first" and "place". If the user then queries for '1st + place',
-**            the tokenizer substitutes "first" for "1st" and the query works
-**            as expected.
-**
-**       <li> By querying the index for all synonyms of each query term
-**            separately. In this case, when tokenizing query text, the
-**            tokenizer may provide multiple synonyms for a single term
-**            within the document. FTS5 then queries the index for each
-**            synonym individually. For example, faced with the query:
-**
-**   <codeblock>
-**     ... MATCH 'first place'</codeblock>
-**
-**            the tokenizer offers both "1st" and "first" as synonyms for the
-**            first token in the MATCH query and FTS5 effectively runs a query
-**            similar to:
-**
-**   <codeblock>
-**     ... MATCH '(first OR 1st) place'</codeblock>
-**
-**            except that, for the purposes of auxiliary functions, the query
-**            still appears to contain just two phrases - "(first OR 1st)"
-**            being treated as a single phrase.
-**
-**       <li> By adding multiple synonyms for a single term to the FTS index.
-**            Using this method, when tokenizing document text, the tokenizer
-**            provides multiple synonyms for each token. So that when a
-**            document such as "I won first place" is tokenized, entries are
-**            added to the FTS index for "i", "won", "first", "1st" and
-**            "place".
-**
-**            This way, even if the tokenizer does not provide synonyms
-**            when tokenizing query text (it should not - to do so would be
-**            inefficient), it doesn't matter if the user queries for
-**            'first + place' or '1st + place', as there are entries in the
-**            FTS index corresponding to both forms of the first token.
-**   </ol>
-**
-**   Whether it is parsing document or query text, any call to xToken that
-**   specifies a <i>tflags</i> argument with the FTS5_TOKEN_COLOCATED bit
-**   is considered to supply a synonym for the previous token. For example,
-**   when parsing the document "I won first place", a tokenizer that supports
-**   synonyms would call xToken() 5 times, as follows:
-**
-**   <codeblock>
-**       xToken(pCtx, 0, "i",                      1,  0,  1);
-**       xToken(pCtx, 0, "won",                    3,  2,  5);
-**       xToken(pCtx, 0, "first",                  5,  6, 11);
-**       xToken(pCtx, FTS5_TOKEN_COLOCATED, "1st", 3,  6, 11);
-**       xToken(pCtx, 0, "place",                  5, 12, 17);
-**</codeblock>
-**
-**   It is an error to specify the FTS5_TOKEN_COLOCATED flag the first time
-**   xToken() is called. Multiple synonyms may be specified for a single token
-**   by making multiple calls to xToken(FTS5_TOKEN_COLOCATED) in sequence.
-**   There is no limit to the number of synonyms that may be provided for a
-**   single token.
-**
-**   In many cases, method (1) above is the best approach. It does not add
-**   extra data to the FTS index or require FTS5 to query for multiple terms,
-**   so it is efficient in terms of disk space and query speed. However, it
-**   does not support prefix queries very well. If, as suggested above, the
-**   token "first" is substituted for "1st" by the tokenizer, then the query:
-**
-**   <codeblock>
-**     ... MATCH '1s*'</codeblock>
-**
-**   will not match documents that contain the token "1st" (as the tokenizer
-**   will probably not map "1s" to any prefix of "first").
-**
-**   For full prefix support, method (3) may be preferred. In this case,
-**   because the index contains entries for both "first" and "1st", prefix
-**   queries such as 'fi*' or '1s*' will match correctly. However, because
-**   extra entries are added to the FTS index, this method uses more space
-**   within the database.
-**
-**   Method (2) offers a midpoint between (1) and (3). Using this method,
-**   a query such as '1s*' will match documents that contain the literal
-**   token "1st", but not "first" (assuming the tokenizer is not able to
-**   provide synonyms for prefixes). However, a non-prefix query like '1st'
-**   will match against "1st" and "first". This method does not require

-# core-utils
-
-Provides common utility functions, data structures (e.g., for iteration), error handling, and abstractions used across multiple `core-*` and `api-*` crates, facilitating interactions with storage and data processing.
-
-## Purpose
-
-This crate contains shared helper code, custom error types, and common traits to reduce duplication and promote consistency across the Embucket codebase.
