Missing support for php 7.2

[gergnz]

I'm not able to use the php7 branch to build against php7.2. While the build completes, the shared object can't be loaded due to a missing symbol, which looks to have changed between php 7.1 and php 7.2: strpprintf

See #11 for instructions on how to compile – Both PHP 7.1 and 7.2 are supported by the underlying modules, however binaries are provided by Amazon only for PHP 7.0 at this time.

I've tried and it's not working. (see my comments re missing symbol strpprintf). It looks like this has changed in zend, and my C isn't good enough to understand what's going on.

Also this comment (#11 (comment)) suggests that it isn't working for others.

I just managed to install PHP 7.2 on ubuntu 16.04 and compile the client based on libmemcached 1.0.8. In case you need the binary to get unblocked, here it is. Let me know if this works for you or not.

AmazonElasticacheClusterClient-PHP72-64bit-libmemcached-1.0.8.tar.gz

@QuChen88 tested on PHP Version 7.2.5-1+ubuntu16.04.1 and it seems to be connecting and doing basics. Will have a better play later.

On PHP 7.2.9-1+ubuntu16.04.1+deb.sury.org+1 via ppa:ondrej/php copy the amazon-elasticache-cluster-client.so from @QuChen88 (#19 (comment)) to /usr/lib/php/20170718/ so php7.2-fpm can find it

Part way through upgrading to PHP 7.2 on Amazon Linux and 💣 💥 turns out that AWS doesn't provide a client yet :-/

[elyobo]

That said, @QuChen88's version above does seem to work for me on the latest Amazon Linux; any news when an "official" version would be available?

[elyobo]

Addendum, we're seeing a lot of logs with Unknown: using touch command with binary protocol is not recommended with libmemcached versions below 1.0.18, please use ascii protocol or upgrade libmemcached with @QuChen88's package above. @QuChen88, given the comments on php-memcached-dev/php-memcached#310 and php-memcached-dev/php-memcached#322 it seems like compiling against a newer libmemcached is probably required to support the default PHP7 behaviour (lazy write enabled).

This worked for me.
OS: ubuntu 18 latest

@gergnz you should close this issue for the best answer of @QuChen88

[powrsurg]

I would say this should be verified on systems besides Ubuntu before closing.

[sodabrew]

As the maintainer of the php-memcached module on which this work is based, I must urge against using older versions of libmemcached with known bugs and deficiencies. What is the problem that is blocking the AWS modifications to libmemcached 1.0.18 from being used here?

[gergnz]

@sodabrew, can you advise on these upstream changes please?

[sodabrew]

Read five comments back, the error message says to use an updated library to avoid a specific bug. That text is meant to be as clear as possible in people’s error logs.

[mosesliao]

is there an aws elastic client memcached for PHP 7.2 in amazon linux?
