format-patch: add '--base' option to record base tree info Maintainers or third party testers may want to know the exact base tree the patch series applies to. Teach git format-patch a '--base' option to record the base tree info and append it at the end of the first message (either the cover letter or the first patch in the series). The base tree info consists of the "base commit", which is a well-known commit that is part of the stable part of the project history everybody else works off of, and zero or more "prerequisite patches", which are well-known patches in flight that is not yet part of the "base commit" that need to be applied on top of "base commit" in topological order before the patches can be applied. The "base commit" is shown as "base-commit: " followed by the 40-hex of the commit object name. A "prerequisite patch" is shown as "prerequisite-patch-id: " followed by the 40-hex "patch id", which can be obtained by passing the patch through the "git patch-id --stable" command. Imagine that on top of the public commit P, you applied well-known patches X, Y and Z from somebody else, and then built your three-patch series A, B, C, the history would be like: ---P---X---Y---Z---A---B---C With "git format-patch --base=P -3 C" (or variants thereof, e.g. with "--cover-letter" of using "Z..C" instead of "-3 C" to specify the range), the base tree information block is shown at the end of the first message the command outputs (either the first patch, or the cover letter), like this: base-commit: P prerequisite-patch-id: X prerequisite-patch-id: Y prerequisite-patch-id: Z Helped-by: Junio C Hamano <gitster@pobox.com> Helped-by: Wu Fengguang <fengguang.wu@intel.com> Signed-off-by: Xiaolong Ye <xiaolong.ye@intel.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 http://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 http://news.gmane.org/gmane.comp.version-control.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):
