Jeff King 63f4a7fc01 pack-check: push oid lookup into loop When we're checking a pack with fsck or verify-pack, we first sort the idx entries by offset, since accessing them in pack order is more efficient. To do so, we loop over them and fill in an array of structs with the offset, object_id, and index position of each, sort the result, and only then do we iterate over the sorted array and process each entry. In order to avoid the memory cost of storing the hash of each object, we just store a pointer into the copy in the mmap'd pack index file. To keep that property even as the rest of the code converted to "struct object_id", commit `9fd750461b` (Convert the verify_pack callback to struct object_id, 2017-05-06) introduced a union in order to type-pun the pointer-to-hash into an object_id struct. But we can make this even simpler by observing that the sort operation doesn't need the object id at all! We only need them one at a time while we actually process each entry. So we can just omit the oid from the struct entirely and load it on the fly into a local variable in the second loop. This gets rid of the type-punning, and lets us directly use the more type-safe nth_packed_object_id(), simplifying the code. And as a bonus, it saves 8 bytes of memory per object. Note that this does mean we'll do the offset lookup for each object before the oid lookup. The oid lookup has more safety checks in it (e.g., for looking past p->num_objects) which in theory protected the offset lookup. But since violating those checks was already a BUG() condition (as described in the previous commit), it's not worth worrying about.

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.

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):

random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
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
