Windows v2-build Error: unsatisfied constraints (The directory is not empty.)

[bitc]

Describe the bug

I did a clean install of

When I ran cabal v2-build, it started running for a while, and then I got the error:

C:\Users\bitc\projects\myproject\dist-newstyle\tmp\src-1777\basement-0.0.11\dist\build: removeDirectoryRecursive:removeContentsRecursive:removePathRecursive:removeContentsRecursive:removePathRecursive:removeContentsRecursive:removePathRecursive:removeContentsRecursive:RemoveDirectory "\\\\?\\C:\\Users\\bitc\\projects\\myproject\\dist-newstyle\\tmp\\src-1777\\basement-0.0.11\\dist\\build": unsatisfied constraints (The directory is not empty.)

The Full log is below.

When I checked the directory, it was actually empty.

When I ran cabal v2-build again, the build resumed, and this time completed successfully.

To Reproduce

I was able to Reproduce! I completely deleted dist-newstyle and my user's cabal directory, and ran again cabal v2-update and cabal v2-build. This time it failed on a different package:

C:\Users\bitc\projects\myproject\dist-newstyle\tmp\src-4000\hashable-1.3.0.0\benchmarks: removeDirectoryRecursive:removeContentsRecursive:removePathRecursive:removeContentsRecursive:removePathRecursive:removeContentsRecursive:RemoveDirectory "\\\\?\\C:\\Users\\bitc\\projects\\myproject\\dist-newstyle\\tmp\\src-4000\\hashable-1.3.0.0\\benchmarks": unsatisfied constraints (The directory is not empty.)

System information

• Windows 7 Professional
• cabal 3.2.0.0
• ghc 8.10.3

This looks similar to #4144 but I am opening a new issue since that one is very old and closed.

[bitc]

I have a wild guess that this may be fixed by #6536

[jneira]

Thanks for reporting it, I am experiencing it too. It would be great to confirm that merged pr fixes it, trying cabal-3.4 (or 3.2 with the patch, it needs be built from source)
Btw, are you on windows 7? or is it reproduced in newer versions too?

[sapek]

I submitted a fix for this some time ago but the maintainer of Win32 package didn't think that was the right place to fix the problem.

[jneira]

it would be nice to see it merged, did you try to move the patch to directory?

[sjakobi]

I've reported the issue in haskell/directory#129.
