--bindir is ignored without warning or suggestion that `--installdir` should be used

[mgajda]

Describe the bug

Using v1-install option --bindir results in no warning, but is silently ignored.
The option is displayed in cabal new-install --help, but redundant with --installdir

To Reproduce

Steps to reproduce the behavior:

$ cabal v2-install --bindir ./output

The resulting binary will not be copied to ./output, nor warning will be issued.

Expected behavior

Since --bindir is accepted, it should be duplicate of --installdir or removed.

System information

• cabal version 3.4.1.0
• ghc version -- irrelevant

Similar problem as with #7437.

I confirm this problem.

This should be resolved by #8556 which removes all installdirs options from new-install (but leaves them for build, etc)

@mgajda and @mouse07410, could you kindly verify with the cabal version on master branch?

@Mikolaj Could you please point me at the artifact (exact location or URL would be fine) that I'd download and experiment with?

[Mikolaj]

@mouse07410: hah, you've edited my comment.

Any artifact from a merged PR should do. E.g., at the very bottom of

https://github.com/haskell/cabal/actions/runs/3716873166

Let me know if that's not enough.

Hmm, did not realize...

https://github.com/haskell/cabal/actions/runs/3716873166

Perhaps I'm being dense, and fighting some weird respiratory virus doesn't make me any sharper :-( . But I saw no artifacts there.

Let me know if that's not enough.

I'm afraid it isn't. If somewhere within those runs is a snippet that places linked cabal binary to somewhere where I can reach it with, e.g., wget or curl - I did not see it.

So, I'd love something like (URL is definitely incorrect, and crafted merely to show what I'm trying to request):
https://github.com/haskell/cabal/actions/runs/3716873166/jobs/123456678/bin/cabal
It would be nice if the job is for macOS and uses GHC-9.0.2, 9.2.5, or 9.4.3.

Otherwise, I'm viewing a ton of validation output, but no artifacts...

@mouse07410 unfortunately, you can't get a direct download link for GitHub artifacts (see actions/upload-artifact#27), and you have to use a web browser to retrieve them. Try again that page, and just Cmd+F (search) for the word Artifact: second occurrence of it should lead you to the links.

Direct link would be possible if we organized nightly pre-releases, as it was suggested in #8541. If you feel energy, feel free to work on it: it's a simple update of the CI with a huge dev experience improvement.

That is fine. My problem is - there doesn't seem to be any artifact on that page.

Try again that page, and just Cmd+F (search) for the word Artifact: second occurrence of it should lead you to the links.

Either we're talking about different pages, or I've no clue whatsoever. Search for "Artifact" found zero entries.

That page only contains logs of "Validate XXX" jobs, "Dogfooding XXX" jobs, and "Validate post job". Trying to dig into any of those logs gives me the standard CI log "Set up job, Run actions/checkput@v3, ..." etc. I don't see any artifact (nor Artifact) anywhere there.

Besides the above, I picked the "Validate for macOS GHC-9.0.2" job
https://github.com/haskell/cabal/actions/runs/3716873166/jobs/6303690863 and tried to "guess" where the artifacts might be: https://github.com/haskell/cabal/actions/runs/3716873166/jobs/6303690863/artifacts

No joy.

This https://github.com/haskell/cabal/actions/artifacts also returns HTTP 404.

And before you ask, this https://github.com/haskell/cabal/actions/artifacts/3716873166/zip also fails with 404.

Trying https://api.github.com/repos/haskell/cabal/actions/artifacts/3716873166/zip gets me

{
  "message": "You must have the actions scope to download artifacts.",
  "documentation_url": "https://docs.github.com/rest/reference/actions#download-an-artifact"
}

My guess is - there are no artifacts on that page. As the proverb goes - "it's hard to search for a black cat in a dark room. Especially if it isn't there".

Would love to show screenshots, but stupid GitHub does not allow uploading them anymore either.

Direct link would be possible if we organized nightly pre-releases, as it was suggested in #8541.

I don't have a lot of time on my hands, especially now - but I'll take a look. In fact, I'm very surprised it hasn't been done yet.

Update

Turns out, there is an extremely convoluted way to get an "artifact". Contrary to expectations, the majority of the validation jobs did not leave one. However, I did find one for macOS, built with GHC-9.2.3. More later.

[Mikolaj]

I'm really surprised. Your browser must be broken somehow, particularly the C-f functionality (you did use it, right? not the "Search" input field of github?). But scrolling the whole page with a scrollbar on the right (not scrolling any sub-pane only) of the original link I posted

https://github.com/haskell/cabal/actions/runs/3716873166

should really show a short "Artifacts" section at the end. If it doesn't, perhaps fire a Linux VM and try again.

Considering that my browser works with everything else (so far), I rather doubt it's broken. Yes, I used Cmd-F (the only way to do a search on the page?).

Damn it! I found it in your newly-provided page by scrolling to the very end the right column.

So, this page https://github.com/haskell/cabal/actions/runs/3716873166/ has it.
That page (original URL given) https://github.com/haskell/cabal/actions/runs/3716873166/jobs/6303690863 does not (the wrong one has "jobs/6303690863" suffix).
Update I've no idea where that ".../jobs/..." URL came from, and why my browser got to it.

Now, to business. Downloaded artifact is installed on my system as cabal-dev.
