Some HTTP authentication schemes, such as NTLM- and Kerberos-based
options, require more than one round trip to authenticate. Currently,
these can only be supported in libcurl, since Git does not have support
for this in the credential helper protocol.
However, in a future commit, we'll add support for this functionality
into the credential helper protocol and Git itself. Because we don't
really want to implement either NTLM or Kerberos, both of which are
complex protocols, we'll want to test this using a fake credential
authentication scheme. In order to do so, update t5563 and its backend
to allow us to accept multiple sets of credentials and respond with
different behavior in each case.
Since we can now provide any number of possible status codes, provide a
non-specific reason phrase so we don't have to generate a more specific
one based on the response. The reason phrase is mandatory according to
the status-line production in RFC 7230, but clients SHOULD ignore it,
and curl does (except to print it).
Each entry in the authorization and challenge fields contains an ID,
which indicates a corresponding credential and response. If the
response is a 200 status, then we continue to execute git-http-backend.
Otherwise, we print the corresponding status and response. If no ID is
matched, we use the default response with a status of 401.
Note that there is an implicit order to the parameters. The ID is
always first and the creds or response value is always last, and
therefore may contain spaces, equals signs, or other arbitrary data.

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).
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).
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
