Context deadline exceeded

[CLanguagePurist]

Description

One of the mirrored project, LLVM/LLVM-project seems to have a problem that anytime I try to open it in gitea server, a 500 error is return with context deadline exceeded which seems to suggest that I am hitting a Time to Live timer limit when attempting to open the page for LLVM mirrored project. I've tried asking about it on matrix chat, checked FAQ, and other google search for this but I was not able to find a solution for this yet.

The local gitea server is running on Proxmox server with about 8 cores, 32 gb of RAM, and 1 TB of storage in LVM Ext4 file system. I also can't reproduce this on https://try.gitea.io since I am unable to get an activation email to try replicating the issue.

Gitea Version

1.17.0-rc1

Can you reproduce the bug on the Gitea demo site?

No

Screenshots

Git Version

2.25.1

Operating System

Ubuntu 20.04.4 LTS

How are you running Gitea?

Using executable download for Linux from tagged release for 1.17.0-rc1, gitea-1.17.0-rc1-linux-amd64 from this page and have done SHA256 checksum comparison and they matched with gitea-1.17.0-rc1-linux-amd64.sha256. I have granted this executable privilege to operates on port 80 and 443 and this server is NOT visible to the public internet and required firewall whitelisted address on the LAN to access the server IE my development machine which also runs Linux.

Database

PostgreSQL

Any clue from system logs? Usually when I get 500 errors like this, it's because of a systems issue, like the database is down or a dependent filesystem isn't mounted or I haven't set the SELinux right labels for it yet.

There's a subtle bug/race in WalkGitLog:

gitea/modules/git/log_name_status.go

Lines 344 to 360 in 966e7bd

	heaploop:
	for {
	select {
	case <-ctx.Done():
	if ctx.Err() == context.DeadlineExceeded {
	break heaploop
	}
	g.Close()
	return nil, ctx.Err()
	default:
	}
	current, err := g.Next(treepath, path2idx, changed, maxpathlen)
	if err != nil {
	if err == context.DeadlineExceeded {
	break heaploop
	}
	g.Close()

At line 357 the error returned is not context.DeadlineExceeded but in fact is a fmt.Errorf("%w - %s", err, stderr)

The err needs to be errors.Unwrap to check if it is a context.DeadlineExceeded.

The system is pretty nominal overall, I can access LLVM-Project repo from within repository folder on the filesystem, so the files are ok as far as access goes. I haven't activated SELinux/Apparmor for this server since the server is not visible to public internet, require public key authentication for SSH, and only allow connections from my devices via IP address that is reserved on the LAN.

PostgreSQL Database seems to have no log that would indicates an error or issue. I am able to access the gitea database without any problem.

Confirming that this is fixed in Release Candidate 2
