Golangci-lint: Frequent "failed to get data from low-level cache" warning

[oschwald]

I have been seeing the following warning quite frequently in both our CI environment and on my local development machine:

level=warning msg="[runner/goanalysis_metalinter/goanalysis] Failed to get persisted facts: failed to get data from low-level cache by key printf/facts for package trace: failed to stat file /home/greg/.cache/golangci-lint/af/aff20f6cd29342c0f0dcc2ea1acf50b374a6cf1954a9287664287e2d313d7244-d: stat /home/greg/.cache/golangci-lint/af/aff20f6cd29342c0f0dcc2ea1acf50b374a6cf1954a9287664287e2d313d7244-d: no such file or directory"

There isn't anything else running that should be deleting these files and we aren't running multiple instances of golangci-lint concurrently.

This has been going on for a month or so, likely starting around the time I upgraded to 1.22.0.

Please let me know if I can supply any additional information.

Just got this as well and was able to resolve it with golangci-lint cache clean. I'm on Mac with golangci-lint 1.23.7.

[ernado]

Hey @skoval00 can you please try the latest version?

I think that I/O should be more robust in v1.27

[skoval00]

@ernado I tried v1.27 with the same result. I'll keep running it non-concurrently because I strongly believe this issue may be related to WSL1 file system performance. Right now I can't switch to WSL2 and I am not sure it will be an easy move in my case.

[ernado]

Looks like we should add a hack in robustio/renamio that will detect WSL1 and apply same logic as for windows.

But WSL1 is deprecated in favor of WSL2, so I'm not sure about priority of this issue, sorry :(
