Description

Sometimes, not systematically, an error appears in the logs, when I click on the the last commit id in any repository, from all places: from 'user activity', from the specific repository 'home page', from the 'commits list', ...
When it happens the error is always the same:

2022/03/04 10:35:56 ...s/gitdiff/gitdiff.go:1418:func1() [E] Unable to open checker for 8fd941c7454eb37aafcac4a6d410d68669efdc5b. Error: failed to run attr-check. Error: context canceled
	Stderr: 

My 'report' was to know if this type of error can affect the integrity of the 'git repository'.

Note: as much as I could check the problem is only for the last commit of the repository!

I attach the complete log of a request that generated the error.

Thanks in advance.

This can be safely ignored.

[fnetX]

Just because I'm curious: What is it about? It's spamming the log every few seconds. Aborted web requests?

[zeripath]

I'll get a fix in - it's my fault they shouldn't have been error level logged.

[robertranjan]

Seeing similar error messages on macOS install as well. (gitea 1.16.3)

[henrythebuilder]

Thanks for support and all Gitea contributors 👍

[robertranjan]

@henrythebuilder, is the commit count on the webpage changes when you push new commits?

It's not changing in my local deployment, not sure it happens to others as well or not? Can you please check in you local deployment of v1.16.3?

[henrythebuilder]

Hi @robertranjan, the commit change after 'manually' refresh the 'home' page of the repo, this seems normal to me, but trying the action you suggest, when I pushed new commits from local repo to gitea I had again the same error:

2022/03/06 17:15:07 ...age_stats_nogogit.go:86:func2() [E] Unable to open checker for 5a6834a4f114de82489eeb3d994663516fe0e42d. Error: failed to run attr-check. Error: context canceled
	Stderr: 

I hope this will help you.

... but according to @zeripath "This can be safely ignored" and it seems that the problem has been identified (#19006) so it probably will be solved early.

[robertranjan]

thanks for checking out the commits counts @henrythebuilder ; refreshing browser didn't update the commit counts for me. It may be related to my upgrade from 1.15.9 to 1.16.3.
