Cirrus-ci-docs: cache is never uploaded ("Some other task has already uploaded cache entry")

[MarcoFalke]

It seems that caches are never uploaded for our repos. For example: https://cirrus-ci.com/task/6360227811426304?command=Upload%20%27ccache%27%20cache#L3

Thus, fetching the cache will fail. https://cirrus-ci.com/task/6360227811426304?command=ccache#L1

The error message "some other task has already uploaded" doesn't make sense because our taks names are unique, so there shouldn't be another task that has already uploaded the cache.

Created https://github.com/cirruslabs/cirrus-ci-agent/pull/78 to log which task is claimed to upload the entry.

Unfortunately, it seems the existing meta information is screwed because of caching on server side so I can't figure out which task is claimed to upload the entry. Will let you know when https://github.com/cirruslabs/cirrus-ci-agent/pull/78 will be deployed so we can troubleshoot further.

The change got deployed so new caches will have proper metadata so we'll be able to track the issue. Let's see what logs will yield.

[MarcoFalke]

For example this task https://cirrus-ci.com/task/6247049978970112?command=Upload%20%27ccache%27%20cache#L3 refers to a pull request having already uploaded: https://cirrus-ci.com/task/6087896912363520

Though, the pull request hasn't uploaded anything either.

That's my bad. This task shows the corrupted metadata because of caching that I was talking about. This claim is wrong. Just deployed the server side change to fix it. Sorry about the noise!

I have the same issue... Check any Ubuntu jobs here: https://cirrus-ci.com/github/slycelote/caide-cpp-inliner
Let me know if my config is incorrect, or what I can do to investigate.

@slycelote Fixed your issue in https://github.com/cirruslabs/cirrus-ci-agent/pull/80 and it just got deployed so new tasks should be able to download caches.

@fkorotkov Thanks!

[MarcoFalke]

This seems to be fixed. Closing for now.
