Patrick Steinhardt f1fb064465 refs/packed: fix BUG when seeking refs with UTF-8 characters It was reported that using git-pull(1) in a repository whose remote contains branches with emojis leads to the following bug: $ git pull remote: Enumerating objects: 161255, done. remote: Counting objects: 100% (55884/55884), done. remote: Compressing objects: 100% (5518/5518), done. remote: Total 161255 (delta 54253), reused 50509 (delta 50364), pack-reused 105371 (from 4) Receiving objects: 100% (161255/161255), 309.90 MiB \| 16.87 MiB/s, done. Resolving deltas: 100% (118048/118048), completed with 13416 local objects. From github.com:github/github 97ab7ae3f3745..8fb2f9fa180ed master -> origin/master [...snip many screenfuls of updates to origin remotes...] BUG: refs/packed-backend.c:984: packed-refs backend yielded reference preceding its prefix error: fetch died of signal 6 This issue bisects to `22600c0452` (refs/iterator: implement seeking for packed-ref iterators, 2025-03-12) where we have implemented seeking for the packed-ref iterator. As part of that change we introduced a check that verifies that the iterator only returns refnames bigger than the prefix. In theory, this check should always hold: when a prefix is set we know that we would've seeked that prefix first, so we should never see a reference sorting before that prefix. But in practice the check itself is misbehaving when handling unicode characters. The particular issue triggered with a branch that got the "shaved ice" unicode character in its name, which is composed of the bytes "0xEE 0x90 0xBF". The bug triggers when we compare the refname "refs/heads/<shaved-ice>" to something like "refs/heads/z", and it specifically hits when comparing the first byte, "0xEE". The root cause is that the most-significant bit of 0xEE is set. The `refname` and `prefix` pointers that we use to compare bytes with one another are both pointers to signed characters. As such, when we dereference the 0xEE byte the result is a _negative_ value, and this value will of course compare smaller than "z". We can see that this issue is avoided in `cmp_packed_refname()`, where we explicitly cast each byte to its unsigned form. Fix the bug by doing the same in `packed_ref_iterator_advance()`.

Git - fast, scalable, distributed revision control system

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.

Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.

Please read the file INSTALL for installation instructions.

Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.

See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-<commandname>.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.

CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).

The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission and Documentation/CodingGuidelines).

Those wishing to help with error message, usage and informational message string translations (localization l10) should see po/README.md (a po file is a Portable Object file that holds the translations).

To subscribe to the list, send an email to git+subscribe@vger.kernel.org (see https://subspace.kernel.org/subscribing.html for details). The mailing list archives are available at https://lore.kernel.org/git/, https://marc.info/?l=git and other archival sites.

Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.

The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.

The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):
