Back in commita562d90a35(merge-ort: fix failing merges in special corner case, 2025-11-03), we hit a rename assertion due to a trivial directory resolution affecting the parent of a cached rename. Since the path didn't need to be considered, we side-stepped it with if (!newinfo) continue; in process_renames(). We have since run into a case in production where a trivial resolution of a file affects the direct target of a cached rename rather than a parent directory of it. Add a testcase demonstrating this additional case. Now, if we were to follow the lead of commita562d90a35, we could resolve this alternate case with an extra condition on the above if: if (!newinfo || newinfo->merged.clean) continue; However, if we had done that earlier, we would have made979ee83e8a(merge-ort: fix corner case recursive submodule/directory conflict handling, 2025-12-29) harder to find and fix, and this particular position for this condition isn't actually at the root of the issue but downstream from it. Instead, let's rip out this if-check froma562d90a35and put in an alternative that more directly addresses trivially resolved paths that happen to be cached renames or parent directories thereof, which is a better fix for the original testcase and which also solves the newly added testcase as well.

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.adoc to get started, then see
Documentation/giteveryday.adoc for a useful minimum set of commands, and
Documentation/git-<commandname>.adoc 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.adoc
(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):
- random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
- stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
- "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
- "goddamn idiotic truckload of sh*t": when it breaks
