Taylor Blau 38ff7cabb6 pack-revindex: write multi-pack reverse indexes Implement the writing half of multi-pack reverse indexes. This is nothing more than the format describe a few patches ago, with a new set of helper functions that will be used to clear out stale .rev files corresponding to old MIDXs. Unfortunately, a very similar comparison function as the one implemented recently in pack-revindex.c is reimplemented here, this time accepting a MIDX-internal type. An effort to DRY these up would create more indirection and overhead than is necessary, so it isn't pursued here. Currently, there are no callers which pass the MIDX_WRITE_REV_INDEX flag, meaning that this is all dead code. But, that won't be the case for long, since subsequent patches will introduce the multi-pack bitmap, which will begin passing this field. (In midx.c:write_midx_internal(), the two adjacent if statements share a conditional, but are written separately since the first one will eventually also handle the MIDX_WRITE_BITMAP flag, which does not yet exist.)

Git - fast, scalable, distributed revision control system

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.

stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
"global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
"goddamn idiotic truckload of sh*t": when it breaks
