This bot is pretty slick!

CI broke

[Mikolaj]

I've dismissed my review, because something is wrong in CI and this needs a look.

[Mikolaj]

The bootstrap CI failure is really misterious, because the changes between 3.6 and master for the related files seem completely irrelevant to it:

Run python3 bootstrap/bootstrap.py -w /opt/ghc/8.10.4/bin/ghc -d bootstrap/linux-8.10.4.json
Traceback (most recent call last):
  File "bootstrap/bootstrap.py", line 389, in <module>
    main()
  File "bootstrap/bootstrap.py", line 346, in main
    ghc = Compiler(args.with_compiler)
  File "bootstrap/bootstrap.py", line 74, in __init__
    raise TypeError(f'GHC {ghc_path} is not a file')
TypeError: GHC /opt/ghc/8.10.4/bin/ghc is not a file

So let me rerun the job instead of debugging further.

[Mikolaj]

Got it! I've rerun the same "linux bootstrap" job for the PR being backported (https://github.com/haskell/cabal/runs/3633407832) and it failed the same on master. So GihHub Actions just switched off 8.10.4. I will try to bump the boostraps to 8.10.7 and see if it works then.

The bootstrap fix is merged with #7657 so rebasin
@Mergifyio rebase

[mergify]

Command rebase: success

Branch has been successfully rebased

LGTM, thanks for the fix for this nasty bug

[jneira]

This is failing due to #7649 so any pr in 3.6 needs #7652 backported

https://github.com/haskell/cabal/runs/3640445372?check_suite_focus=true

[Mikolaj]

The CI failures are as expected at this stage of 3.6 CI fixing.

[Mikolaj]

As soon as #7664 gets merged to 3.6 by mergifyIO, we can backport this again to 3.6 and it should merge correctly and pass CI fine this time. [Edit: error, wrong PR, #7652 is the one.]
