add_to_index(): convert forgotten HASH_RENORMALIZE check Commit 9e5da3d055 (add: use separate ADD_CACHE_RENORMALIZE flag, 2019-01-17) switched out using HASH_RENORMALIZE in our flags field for a new ADD_CACHE_RENORMALIZE flag. However, it forgot to convert one of the checks for HASH_RENORMALIZE into the new flag, which totally broke "git add --renormalize". To make matters even more confusing, the resulting code would racily pass the tests! The forgotten check was responsible for defeating the up-to-date check of the index entry. That meant that "git add --renormalize" would refuse to renormalize things that appeared stat-clean. But most of the time the test commands run fast enough that the file mtime is the same as the index mtime. And thus we err on the conservative side and re-hash the file, which is what "--renormalize" would have wanted. But if you're unlucky and cross that one-second boundary between writing the file and writing the index (which is more likely to happen on a slow or heavily-loaded system), then the file appears stat-clean. And "--renormalize" would effectively do nothing. The fix is straightforward: convert this check to use the right flag.

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-.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). To subscribe to the list, send an email with just “subscribe git” in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://public-inbox.org/git/, http://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):
