pack-objects: parameterize pack-reuse routines over a single pack The routines pack-objects uses to perform verbatim pack-reuse are: - write_reused_pack_one() - write_reused_pack_verbatim() - write_reused_pack() , all of which assume that there is exactly one packfile being reused: the global constant `reuse_packfile`. Prepare for reusing objects from multiple packs by making reuse packfile a parameter of each of the above functions in preparation for calling these functions in a loop with multiple packfiles. Note that we still have the global "reuse_packfile", but pass it through each of the above function's parameter lists, eliminating all but one direct access (the top-level caller in `write_pack_file()`). Even after this series, we will still have a global, but it will hold the array of reusable packfiles, and we'll pass them one at a time to these functions in a loop. Note also that we will eventually need to pass a `bitmapped_pack` instead of a `packed_git` in order to hold onto additional information required for reuse (such as the bit position of the first object belonging to that pack). But that change will be made in a future commit so as to minimize the noise below as much as possible. Signed-off-by: Taylor Blau <me@ttaylorr.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-<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 with just “subscribe git” in the body to majordomo@vger.kernel.org (not the Git list). 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):
