Description

When trying to open one of my repos in the Gitea web interface, I receive an Internal Server Error 500. Checking the log file, I see:

.../xorm/session_raw.go:76:queryRows() [I] [SQL] SELECT `id`, `uid`, `repo_id` FROM `star` WHERE `uid`=? AND `repo_id`=? LIMIT 1 []interface {}{1, 2} - took: 0s
...ules/context/repo.go:606:func1() [E] GetBranchCommit: packfile not found

(I removed the timestamp)

Can I provide anything else to help in/advance the analysis of the error?

I've had just the same error.
git fsck and git fsck --full on the repository stored in gitea did not report anything broken and the error persists after a git repack.
The error message seems to come from go-git: https://github.com/src-d/go-git/blob/eb243ba9a55ac029ab3f9b15157920c46e24078b/storage/filesystem/dotgit/dotgit.go#L268

Pushing another commit to the default branch on my repository opens the repository again, but looking at the commit history does produce a 500 error due to

...uters/repo/commit.go:62:Commits() [E] CommitsByRange: packfile not found

For me this looks to be a bug in go-git not handling some case in a commit properly (as git itself does not report any errors)

we have the same problem with one of our repositories - when clicking on the repository in the web interface we get error 500

Log entry:
.../xorm/session_get.go:99:nocacheGet() [I] [SQL] SELECT id, uid, repo_id FROM star WHERE uid=? AND repo_id=? LIMIT 1 []interface {}{1, 5}

@pampersrocker could you send an issue to https://github.com/src-d/go-git

[pampersrocker]

If you look at the issues in src-d/go-git ( src-d/go-git#1223 , src-d/go-git#1149 , src-d/go-git#1153 ) this is caused when a git gc run is not completed successfully and .tmp files reside in the .git/objects/packs directory.

A workaround for now is to manually run git gc in the affected repositories and let it complete. This fixed it on my end.
The actual fix for this issue seems to be already discussed in the mentioned src-d/go-git issues.

manually triggered garbage collection via gitea site administration page and the issue is fixed. Thank you!

Manually running git gc did the trick for me.
Thanks!
