commit-graph: fix generation number v2 overflow values The Generation Data Chunk was implemented and tested in e8b63005c (commit-graph: implement generation data chunk, 2021-01-16), but the test was carefully constructed to work on systems with 32-bit dates. Since the corrected commit date offsets still required more than 31 bits, this triggered writing the generation_data_overflow chunk. However, upon closer look, the write_graph_chunk_generation_data_overflow() method writes the offsets to the chunk (as dictated by the format) but fill_commit_graph_info() treats the value in the chunk as if it is the full corrected commit date (not an offset). For some reason, this does not cause an issue when using the FUTURE_DATE specified in t5318-commit-graph.sh, but it does show up as a failure in 'git commit-graph verify' if we increase that FUTURE_DATE to be above four billion. Fix this error and create a 64-bit timestamp version of the test so we can test these larger values.

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). 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://lore.kernel.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):
