When operating with the stateless RPC mode, we will receive a nonce issued by another instance of us that advertised our capability and refs some time ago. Update the logic to check received nonce to detect this case, compute how much time has passed since the nonce was issued and report the status with a new environment variable GIT_PUSH_CERT_NONCE_SLOP to the hooks. GIT_PUSH_CERT_NONCE_STATUS will report "SLOP" in such a case. The hooks are free to decide how large a slop it is willing to accept. Strictly speaking, the "nonce" is not really a "nonce" anymore in the stateless RPC mode, as it will happily take any "nonce" issued by it (which is protected by HMAC and its secret key) as long as it is fresh enough. The degree of this security degradation, relative to the native protocol, is about the same as the "we make sure that the 'git push' decided to update our refs with new objects based on the freshest observation of our refs by making sure the values they claim the original value of the refs they ask us to update exactly match the current state" security is loosened to accomodate the stateless RPC mode in the existing code without this series, so there is no need for those who are already using smart HTTP to push to their repositories to be alarmed any more than they already are. In addition, the server operator can set receive.certnonceslop configuration variable to specify how stale a nonce can be (in seconds). When this variable is set, and if the nonce received in the certificate that passes the HMAC check was less than that many seconds old, hooks are given "OK" in GIT_PUSH_CERT_NONCE_STATUS (instead of "SLOP") and the received nonce value is given in GIT_PUSH_CERT_NONCE, which makes it easier for a simple-minded hook to check if the certificate we received is recent enough.

////////////////////////////////////////////////////////////////
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/everyday.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.
