GIT 1.3.0-rc2
Set HTTP user agent to git/GIT_VERSION
git-ls-remote: send no-cache header when fetching info/refs
Bunch of cleanups with a few notable enhancements since
1.3.0-rc1:
- revision traversal infrastructure is updated so that
existence of paths limiters and/or --max-age does not cause
it to call limit_list(). This helps the latency working with
the command quite a bit.
- comes with updated gitk.
One notable fix is to make sure that the IO is restarted upon
signal even on platforms whose default signal semantics is not
to do so. This is the fix for the notorious "clone is broken
since 1.2.2 on Solaris" problem.

git-diff-* --pickaxe-regex will change the -S pickaxe to match

The regex.h library is a rather stupid interface and I like pcre too, but
with any luck it will be everywhere we will want to run Git on, it being
POSIX.2 and all. I'm not sure if we can expect platforms like AIX to

Might as well ape the sigaction change in read-tree.c to avoid
the same potential problems. The fprintf status output will
be overwritten in a second, so don't bother guarding it. Do
move the fputc after disabling SIGALRM to ensure we go to the
next line, though.
Also add a NO_SA_RESTART option in the Makefile in case someone
doesn't have SA_RESTART but does restart (maybe older HP/UX?).
We want the builder to chose this specifically in case the
system both lacks SA_RESTART and does not restart stdio calls;
a compat #define in git-compat-utils.h would silently allow
broken systems.

* jc/clone:
git-clone: fix handling of upsteram whose HEAD does not point at master.
fix repacking with lots of tags
Documentation: revise top of git man page
When cloning from a remote repository that has master, main, and
origin branches _and_ with the HEAD pointing at main branch, we
did quite confused things during clone. So this cleans things
up. The behaviour is a bit different between separate remotes/
layout and the mixed branches layout.
The newer layout with $GIT_DIR/refs/remotes/$origin/, things are
simpler and more transparent:
- remote branches are copied to refs/remotes/$origin/.
- HEAD points at the branch with the same name as the remote
HEAD points at, and starts at where the remote HEAD points at.
- $GIT_DIR/remotes/$origin file is set up to fetch all remote
branches, and merge the branch HEAD pointed at at the time of
the cloning.
Everything-in-refs/heads layout was the more confused one, but
cleaned up like this:
- remote branches are copied to refs/heads, but the branch
"$origin" is not copied, instead a copy of the branch the
remote HEAD points at is created there.
- HEAD points at the branch with the same name as the remote
HEAD points at, and starts at where the remote HEAD points at.
- $GIT_DIR/remotes/$origin file is set up to fetch all remote
branches except "$origin", and merge the branch HEAD pointed
at at the time of the cloning.
With this, the remote has master, main and origin, and its HEAD
points at main, you could:
git clone $URL --origin upstream
to use refs/heads/upstream as the tracking branch for remote
"main", and your primary working branch will also be "main".
"master" and "origin" are used to track the corresponding remote
branches and with this setup they do not have any special meaning.

I'm afraid I'll be accused of trying to suck all the jokes and the
personality out of the git documentation. I'm not! Really!
That said, "man git" is one of the first things a new user is likely try,
and it seems a little cruel to start off with a somewhat obscure joke
about the architecture of git.
So instead I'm trying for a relatively straightforward description of what
git does, and what features distinguish it from other systems, together
with immediate links to introductory documentation.
I also did some minor reorganization in an attempt to clarify the
classification of commands. And revised a bit for conciseness (as is
obvious from the diffstat--hopefully I didn't cut anything important).

This is the "letter of the law" version of using fgets() properly in the

What ends up not working very well at all is the combination of
"--topo-order" and the output filter in get_revision. It will
return NULL when we see the first commit out of date-order, even
if we have other commits coming.
So we really should do the "past the date order" thing in
get_revision() only if we have _not_ done it already in
limit_list().
Something like this.
The easiest way to test this is with just
gitk --since=3.days.ago
on the kernel tree. Without this patch, it tends to be pretty obviously
broken.

This makes git-rev-list able to do path-limiting without having to parse
all of history before it starts showing the results.
This makes things like "git log -- pathname" much more pleasant to use.
This is actually a pretty small patch, and the biggest part of it is
purely cleanups (turning the "goto next" statements into "continue"), but
it's conceptually a lot bigger than it looks.
What it does is that if you do a path-limited revision list, and you do
_not_ ask for pseudo-parenthood information, it won't do all the
path-limiting up-front, but instead do it incrementally in
"get_revision()".
This is an absolutely huge deal for anything like "git log -- <pathname>",
but also for some things that we don't do yet - like the "find where
things changed" logic I've described elsewhere, where we want to find the
previous revision that changed a file.
The reason I put "RFC" in the subject line is that while I've validated it
various ways, like doing
git-rev-list HEAD -- drivers/char/ | md5sum
before-and-after on the kernel archive, it's "git-rev-list" after all. In
other words, it's that really really subtle and complex central piece of
software. So while I think this is important and should go in asap, I also
think it should get lots of testing and eyeballs looking at the code.
Btw, don't even bother testing this with the git archive. git itself is so
small that parsing the whole revision history for it takes about a second
even with path limiting. The thing that _really_ shows this off is doing
git log drivers/
on the kernel archive, or even better, on the _historic_ kernel archive.
With this change, the response is instantaneous (although seeking to the
end of the result will obviously take as long as it ever did). Before this
change, the command would think about the result for tens of seconds - or
even minutes, in the case of the bigger old kernel archive - before
starting to output the results.
NOTE NOTE NOTE! Using path limiting with things like "gitk", which uses
the "--parents" flag to actually generate a pseudo-history of the
resulting commits won't actually see the improvement in interactivity,
since that forces git-rev-list to do the whole-history thing after all.
MAYBE we can fix that too at some point, but I won't promise anything.
