No cache saved on Windows?

[SimonHeybrock]

Having trouble with ccache on Windows (thanks for adding support!). My cache is empty for now, so no hits are reported. But there does appear to be something in the cache (and my cmake found ccache): Cache size (GB): 0.09 / 0.50 (18.79 %). Yet, nothing is uploaded.

This is the output I get:

+ ccache -s -v

Not saving cache because no objects are cached.

@jonashaag can you have a look?

[jonashaag]

@SimonHeybrock can you please share a link to an action run?

[SimonHeybrock]

@jonashaag See https://github.com/scipp/scipp/actions/runs/2033203851.

[jonashaag]

btw @SimonHeybrock you might want to try https://github.com/mamba-org/provision-with-micromamba with cache-env: true to remove that slow Conda env setup :)

[jonashaag]

Found it, bad regex /Files:.+0/, I wanted to match Files: 0 but it also matches something like Files: 350 🤦

[jonashaag]

Added a fix here #54

[hendrikmuhs]

@jonashaag #54 is still marked as draft. By accident or intentional? I like to either split out the fix or get #54 ready to go.

Hello, I am still having this issue: Not saving cache because no objects are cached. on windows.
I just made a small repo example to reproduce it: https://github.com/alemuntoni/ccache-hello-world)

here the workflow file and here the workflow run.

You can see that I made also similar workflows for linux and macos, which work fine.

Am I doing something wrong?

[jonashaag]

Did you check if some of the other windows related bug reports in this repo apply to your use case?

The important info from your run:

  C:\ProgramData\Chocolatey\bin\ccache.exe -s
  cache directory                     C:\Users\runneradmin\AppData\Roaming/ccache
  primary config                      C:\Users\runneradmin\AppData\Roaming/ccache/ccache.conf
  secondary config (readonly)         R:/winlibs64_stage/inst_ccache-4.3/etc/ccache.conf
  cache hit (direct)                     0
  cache hit (preprocessed)               0
  cache miss                             0
  cache hit rate                      0.00 %
  cleanups performed                     0
  files in cache                         0
  cache size                           0.0 kB
  max cache size                       5.0 GB

Ccache isn't called, you should have at least 1 cache miss.

FWIW, a closed issue isn't the proper place to discuss your problem, IMO it is different to the one of the original thread opener. Either create a new issue or open a thread under discussions.

[alemuntoni]

Ok, I wrote here since it seemed to be the same problem (or similar, at least). I'll open a new issue!
