curl supports a few options to control when and how often it should
instruct the OS to send TCP keepalives, like KEEPIDLE, KEEPINTVL, and
KEEPCNT. Until this point, there hasn't been a way for users to change
what values are used for these options, forcing them to rely on curl's
defaults.
But we do unconditionally enable TCP keepalives without giving users an
ability to tweak any fine-grained parameters. Ordinarily this isn't a
problem, particularly for users that have fast-enough connections,
and/or are talking to a server that has generous or nonexistent
thresholds for killing a connection it hasn't heard from in a while.
But it can present a problem when one or both of those assumptions fail.
For instance, I can reliably get an in-progress clone to be killed from
the remote end when cloning from some forges while using trickle to
limit my clone's bandwidth.
For those users and others who wish to more finely tune the OS's
keepalive behavior, expose configuration and environment variables which
allow setting curl's KEEPIDLE, KEEPINTVL, and KEEPCNT options.
Note that while KEEPIDLE and KEEPINTVL were added in curl 7.25.0,
KEEPCNT was added much more recently in curl 8.9.0. Per

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.adoc to get started, then see
Documentation/giteveryday.adoc for a useful minimum set of commands, and
Documentation/git-<commandname>.adoc 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.adoc
(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 and Documentation/CodingGuidelines).
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).
To subscribe to the list, send an email to git+subscribe@vger.kernel.org (see https://subspace.kernel.org/subscribing.html for details). The mailing list archives are available at https://lore.kernel.org/git/, https://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
