Currently, send_info() only checks for existence when the attribute 'size' is also requested. Requesting a bare OID, without attributes only echoes back the OID. Extract the existence check to be done regardless of the number of attributes requested. While at it, introduce a wrapper called get_object_info() similar to odb_read_object_info() that returns OBJ_BAD on fail and adds OBJECT_INFO_SKIP_FETCH_OBJECT and OBJECT_INFO_QUICK flags. OBJECT_INFO_SKIP_FETCH_OBJECT is so a server with a partial clone doesn't trigger fetching objects when it gets an object-info request with an OID that is not available locally. A server should only report what it has locally. Tighten the condition used to determine whether an object is recognized. get_object_info() returns OBJ_BAD for unknown objects, but OBJ_NONE (0) can also mean "not found". Change the check from '< 0' to '<= OBJ_NONE' to cover both as unrecognized. With this patch, a bare OID has two possible responses: 1. Recognized OID: the server answers with "<OID>" 2. Unrecognized OID: the server answers with "<OID> SP" Update the object-info section in 'gitprotocol-v2.adoc': - Require full obj-oid explicitly. - Fix parentheses. - Define obj-size explicitly. - Make obj-size optional in obj-info and document the behavior for unrecognized object IDs. - Describe the attr header as zero or more pkt-lines, one per attribute, matching what the server implements. A request with no attributes gets no header. Signed-off-by: Pablo Sabater <pabloosabaterr@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
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.adoc to get started, then see
Documentation/giteveryday.adoc for a useful minimum set of commands, and
Documentation/git-<commandname>.adoc 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.adoc
(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 to git+subscribe@vger.kernel.org (see https://subspace.kernel.org/subscribing.html for details). The mailing list archives are available at https://lore.kernel.org/git/, https://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
