replace-object: check_replace_refs is safe in multi repo environment In e1111cef23 (inline lookup_replace_object() calls, 2011-05-15) a shortcut for checking the object replacement was added by setting check_replace_refs to 0 once the replacements were evaluated to not exist. This works fine in with the assumption of only one repository in existence. The assumption won't hold true any more when we work on multiple instances of a repository structs (e.g. one struct per submodule), as the first repository to be inspected may have no replacements and would set the global variable. Other repositories would then completely omit their evaluation of replacements. This reverts back the meaning of the flag `check_replace_refs` of "Do we need to check with the lookup table?" to "Do we need to read the replacement definition?", adding the bypassing logic to lookup_replace_object after the replacement definition was read. As with the original patch, delay the renaming of the global variable Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
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.
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):
