Blake Burkhart f4113cac0c http: limit redirection to protocol-whitelist Previously, libcurl would follow redirection to any protocol it was compiled for support with. This is desirable to allow redirection from HTTP to HTTPS. However, it would even successfully allow redirection from HTTP to SFTP, a protocol that git does not otherwise support at all. Furthermore git's new protocol-whitelisting could be bypassed by following a redirect within the remote helper, as it was only enforced at transport selection time. This patch limits redirects within libcurl to HTTP, HTTPS, FTP and FTPS. If there is a protocol-whitelist present, this list is limited to those also allowed by the whitelist. As redirection happens from within libcurl, it is impossible for an HTTP redirect to a protocol implemented within another remote helper. When the curl version git was compiled with is too old to support restrictions on protocol redirection, we warn the user if GIT_ALLOW_PROTOCOL restrictions were requested. This is a little inaccurate, as even without that variable in the environment, we would still restrict SFTP, etc, and we do not warn in that case. But anything else means we would literally warn every time git accesses an http remote. This commit includes a test, but it is not as robust as we would hope. It redirects an http request to ftp, and checks that curl complained about the protocol, which means that we are relying on curl's specific error message to know what happened. Ideally we would redirect to a working ftp server and confirm that we can clone without protocol restrictions, and not with them. But we do not have a portable way of providing an ftp server, nor any other protocol that curl supports (https is the closest, but we would have to deal with certificates).

////////////////////////////////////////////////////////////////

	Git - the stupid content tracker

////////////////////////////////////////////////////////////////

"git" can mean anything, 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

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.

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).

Many Git online resources are accessible from http://git-scm.com/
including full documentation and Git related tools.

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 http://news.gmane.org/gmane.comp.version-control.git/,
http://marc.info/?l=git and other archival sites.

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.
