Warnings in caching steps

See original GitHub issue

First off, I love your actions. I just wanted to have said that 😄

With the new GitHub Actions Summary window, warnings are more visible. We noticed we get two warnings during cached run-vcpkg runs on Windows only (Mac doesn’t have this issue, it seems).

Warning: restoreCache() failed once: 'Error: Tar failed with error: The process 'C:\windows\System32\tar.exe' failed with exit code 1' , retrying... Caused by:

  c:/vcpkg/.git/objects/pack/pack-7330effa4c511288dc38e7d7971f203d2a4a3a23.idx: Can't unlink already-existing object
  c:/vcpkg/.git/objects/pack/pack-7330effa4c511288dc38e7d7971f203d2a4a3a23.pack: Can't unlink already-existing object

(and this error repeats a second time)

Warning: reserveCache failed: Cache already exists. Scope: refs/heads/master, Key: submodGitId=0a457099416a843f442b6c2275b2ec57239b50d9-args=-2010035955-os=1553167195-appendedKey=42-triplet=867608379, Version: e596d9224b0d5487c49893de7ad8700f61714e1ba95b948df70e6f4d9d37eb16

Is there anything you could do to mute those warnings by any chance? 😄

Cheers!

@TrueBrain right, I even already seen this problem in the past but totally forgot about it.

By reading various open issues, in particular this one on the GitHub runner OS images and this other on @action/cache, the solution is to change the @actions/cache’s NPM package to use the GNU tar rather than the BSD one on Windows environments. And also passing in “–force-local” flag.

Whether there is anything sensible that can be done on run-vcpkg until this is fixed upstream, I am open to suggestions.

One potential hack is to rename the BSD tar.exe to anything: running the restore of the cache will then use the GNU one in the Git’s bin directory. Then revert the renaming.

@Shatur95 as soon a workaround is found and known to not have side effects, I would then include it in the action. I’d try by prepending to the path the GNU tar contained in the Git’s bin directory. I haven’t yet, anyone can beat me to it and create a PR for making this change 😃
