cgit: Fix guessing default branch

2026-05-21T13:31:21Z

Even when HEAD is set to "main" in a repository, cgit still uses the "master" branch to detect the age of the last commit. Example: $ cat repositories/openwrt/openwrt.git/HEAD ref: refs/heads/main $ stat repositories/openwrt/openwrt.git/refs/heads/master Modify: 2024-02-22 23:00:01.285731731 +0000 $ stat repositories/openwrt/openwrt.git/refs/heads/main Modify: 2026-02-27 15:33:49.506017172 +0000 In this situation, cgit displays "25 months" for this repository on the index page. I guess the internal format for HEAD has changed at some point, so it needs to be taken into account when parsing it in cgit. Signed-off-by: Baptiste Jonglez

use buffered stdio

2026-05-21T13:27:06Z

Our generation of HTML triggers many small write(2) syscalls which is inefficient. Time output on a horrible query against my git.git mirror shows significant performance improvement: QUERY_STRING='id=2b93bfac0f5bcabbf60f174f4e7bfa9e318e64d5&id2=d6da71a9d16b8cf27f9d8f90692d3625c849cbc8' PATH_INFO=/mirrors/git.git/diff export QUERY_STRING PATH_INFO time ./cgit >/dev/null Before: real 0m1.585s user 0m0.904s sys 0m0.658s After: real 0m0.750s user 0m0.666s sys 0m0.076s Signed-off-by: Eric Wong Signed-off-by: Alyssa Ross

cgit: truncate all config values at the newline

2026-05-04T16:28:27Z

These would be largely invalid anyway (save, I suppose, for Linux file paths that technically can contain new lines). The actual problem is that these get printed back out into cached -- and trusted -- cgitrc files, and if the fields have newlines, the git-config way of less trusted users configuring repos on a shared system can be abused to inject newlines, which then can be used to smuggle global options (including filters, which execute code) into the cached cgitrc. So now, only ever duplicate up to the newline, when dealing with these inputs. Reported-by: Adrian Denkiewicz Signed-off-by: Jason A. Donenfeld

cgit: devirtualize repo_config

2026-05-04T16:28:27Z

There's no reason to pass around function pointers. It was never used for anything beyond one function. Signed-off-by: Jason A. Donenfeld

cgit: override die routine globally

2026-03-10T21:19:00Z

We don't get any return value from compile_grep_patterns calling compile_regexp_failed, causing the default die routine to print to stderr and then for cgit to exit ungracefully. Instead override the default die routine to show a normal error page. Perhaps compile_grep_patterns ought to change upstream to return an error. But this commit here will handle future issues as well, so perhaps not a bad idea to do anyway.

This exists for other CPU heavy operations like blame, but doesn't for the follow functionality. Add it for that. Signed-off-by: Jason A. Donenfeld
