http: normalize curl results for dumb loose and alternates fetches If the dumb-http walker encounters a 404 when fetching a loose object, it then looks at any http-alternates for the object. The 404 check is implemented by missing_target(), which checks not only the http code, but also that we got an http error from the CURLcode. That broke when we stopped using CURLOPT_FAILONERROR in 17966c0a63 (http: avoid disconnecting on 404s for loose objects, 2016-07-11), since our CURLcode will now be CURLE_OK. As a result, fetching over dumb-http from a repository with alternates could result in Git printing "Unable to find abcd1234..." and aborting. We could probably fix this just by loosening missing_target(). However, there's other code which looks at the curl result, and it would have to be tweaked as well. Instead, let's just normalize the result the same way the smart-http code does. There's a similar case in processing the alternates (where we failover from "info/http-alternates" to "info/alternates"). We'll give it the same treatment. After this patch, we should be hitting all code paths that need this normalization (notably absent here is the http_pack_request path, but it does not use FAILONERROR, nor missing_target()).

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-.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://public-inbox.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):
