As of curl 7.66.0, we don't need to manually specify a "chunked"
Transfer-Encoding header. Instead, modern curl deduces the need for it
in a POST that has a POSTFIELDSIZE of -1 and uses READFUNCTION rather
than POSTFIELDS.
That version is recent enough that we can't just drop the header; we
need to do so conditionally. Since it's only a single line, it seems
like the simplest thing would just be to keep setting it unconditionally
(after all, the #ifdefs are much longer than the actual code). But
there's another wrinkle: HTTP/2.
Curl may choose to use HTTP/2 under the hood if the server supports it.
And in that protocol, we do not use the chunked encoding for streaming
at all. Most versions of curl handle this just fine by recognizing and
removing the header. But there's a regression in curl 8.7.0 and 8.7.1
where it doesn't, and large requests over HTTP/2 are broken (which t5559
notices). That regression has since been fixed upstream, but not yet
released.
Make the setting of this header conditional, which will let Git work
even with those buggy curl versions. And as a bonus, it serves as a
reminder that we can eventually clean up the code as we bump the
supported curl versions.
This is a backport of 92a209bf24 (remote-curl: add Transfer-Encoding
header only for older curl, 2024-04-05) into the `maint-2.39` branch.

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).
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):
- 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
