remote-curl: make --force-with-lease work with non-ASCII ref names When we invoke a remote transport helper and pass an option with an argument, we quote the argument as a C-style string if necessary. This is the case for the cas option, which implements the --force-with-lease command-line flag, when we're passing a non-ASCII refname. However, the remote curl helper isn't designed to parse such an argument, meaning that if we try to use --force-with-lease with an HTTP push and a non-ASCII refname, we get an error like this: error: cannot parse expected object name '0000000000000000000000000000000000000000"' Note the double quote, which get_oid has reminded us is not valid in an hex object ID. Even if we had been able to parse it, we would send the wrong data to the server: we'd send an escaped ref, which would not behave as the user wanted and might accidentally result in updating or deleting a ref we hadn't intended. Since we need to expect a quoted C-style string here, just check if the first argument is a double quote, and if so, unquote it. Note that if the refname contains a double quote, then we will have double-quoted it already, so there is no ambiguity. We test for this case only in the smart protocol, since the DAV-based protocol is not capable of handling this capability. We use UTF-8 because this is nicer in our tests and friendlier to Windows, but the code should work for all non-ASCII refs. While we're at it, since the name of the option is now well established and isn't going to change, let's inline it instead of using the #define constant.

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):
