[PATCH] diffcore-pickaxe: switch to "counting" behaviour.
Instead of finding old/new pair that one side has and the
other side does not have the specified string, find old/new pair
that contains the specified string as a substring different
number of times. This would still not catch a case where you
introduce two static variable declarations and remove two static
function definitions from a file with -S"static", but would make
it behave a bit more intuitively.

Add a "git rename" to help with - surprise surprise - renames
It's stupid. We'd want to rename directories too, but this doesn't do
that yet - easy enough to do per se, we just need to carefully list all
the pathnames that got moved (and remember to ignore the files that
weren't tracked but are in the subdirectory that got moved).
Doing the directory case will require a bit more scripting.. Something like
Rename the "tools" programs to also have the "git-" prefix
Hey, people are using them, and we have an install target for them, so
make sure that we can actually install them sanely without disturbing
the namespace.
The git-update-server-info command prepares informational files
to help clients discover the contents of a repository, and pull
from it via a dumb transport protocols. Currently, the
following files are produced.
- The $repo/info/refs file lists the name of heads and tags
available in the $repo/refs/ directory, along with their
SHA1. This can be used by git-ls-remote command running on
the client side.
- The $repo/info/rev-cache file describes the commit ancestry
reachable from references in the $repo/refs/ directory. This
file is in an append-only binary format to make the server
side friendly to rsync mirroring scheme, and can be read by
git-show-rev-cache command.
- The $repo/objects/info/pack file lists the name of the packs
available, the interdependencies among them, and the head
commits and tags contained in them. Along with the other two
files, this is designed to help clients to make smart pull
decisions.
The git-receive-pack command is changed to invoke it at the end,
so just after a push to a public repository finishes via "git
push", the server info is automatically updated.
In addition, building of the rev-cache file can be done by a
standalone git-build-rev-cache command separately.

Update tutorial.txt branches/tags to use the nicer helper syntax
Teach people to use "git tag <tag-name>" instead of writing the current
HEAD by hand into the .git/refs/tags/<tag-name> file. Most people
probably don't really want to know about how git does things internally.
A simple tag is just a direct pointer to the object, while a signed tag
is a pointer to a "tag object" that has a pgp signature and points to
the object we tagged.
Use "git tag -s tagname" to create a signed tag.
The "-f" flag overwrites any previous tag of that name (useful if you
update a tag to point to a newer version for things like "latest" etc
tags that aren't necessarily static versions).
Some people split their long E-mail address over two lines
using the RFC2822 header "folding". We can lose authorship
information this way, so make a minimum effort to deal with it,
instead of special casing only the "Subject:" field.
We could teach mailsplit to unfold the folded header, but
teaching mailinfo about folding would make more sense; a single
message can be fed to mailinfo without going through mailsplit.

[PATCH] Deb packaging needs two more configuration files
The deb package building needs these two new files to work correctly.
debian/compat sets the rules under which the debhelper scripts (dh_*)
operate.
debian/git-core.install tells dh_install what files to install in each
package that is generated. There is only one package being generated,
so all files go into it.

find stuff I had missed:

The Deb packages were missing a dependency on "build install" from the
binary target - this fixes that, and cleans up some inconsistencies
elsewhere in the rulesets.
Traditionally, Debian packaging uses a file called "build-stamp" (or
"install-stamp", etc) in the main source tree. The initial deb package
support for Git tried to move this "build-stamp" file into the debian/
directory, but some instances were missed. That problem, however, was
incidental - the real fix is the missing dependency mentioned above.

Be more aggressive about marking trees uninteresting
We'll mark all the trees at the edges (as deep as we had to go to
realize that we have all the commits needed) as uninteresting.
Otherwise we'll occasionally list a lot of objects that were actually
available at the edge in a commit that we just never ended up parsing
because we could determine early that we had all relevant commits.
NOTE! The object listing is still just a _heuristic_. It's guaranteed
to list a superset of the actual new objects, but there might be the
occasional old object in the list, just because the commit that
referenced it was much further back in the history.
For example, let's say that a recent commit is a revert of part of the
tree to much older state: since we didn't walk _that_ far back in the
commit history tree to list the commits necessary, git-rev-tree will
never have marked the old objects uninteresting, and we'll end up
listing them as "new".

[PATCH] Help scripts that use git-rev-parse to grok args with SP/TAB/LF
The git-rev-parse command uses LF to separate each argument it
parses, so its users at least need to set IFS to LF to be able
to handle filenames with embedded SPs and TABs. Some commands,
however, can take and do expect arguments with embedded LF,
notably, "-S" (pickaxe) of diff family, so even this workaround
does not work for them.
When --sq flag to git-rev-parse is given, instead of showing one
argument per line, it outputs arguments quoted for consumption
with "eval" by the caller, to remedy this situation.
As an example, this patch converts git-whatchanged to use this
new feature.

[PATCH] git-format-patch-script and mailinfo updates.
- avoid duplicating [PATCH] in the commit message body if the
original commit has it already (happens for commits done from
mails via applymbox).
- check if the commit author is different from the one who is
running the script, and emit an appropriate "From:" and
"Date: " lines to the output.
- with '--date', emit "Date: " line to preserve the original
author date even for the user's own commit.
- teach mailinfo to grok not just "From: " but "Date: ".
The patch e-mail output by format-patch starts with the first
line from the original commit message, prefixed with [PATCH],
and optionally a From: line if you are reformatting a patch
obtained from somebody else, a Date: line from the original
commit if (1) --date is specified or (2) for somebody else's
patch, and the rest of the commit message body.
Expected use of this is to move the title line from the commit
to Subject: when sending it via an e-mail, and leave the From:
and the Date: lines as the first lines of your message.
The mailinfo command has been changed to read Date: (in addition
to From: it already understands) and do sensible things when
running applymbox.

git-send-pack: verify that sender is a proper superset of receiver
This should make sure that if you have multiple people pushing to the
same tree, they cannot overwrite each others work, but have to merge
before being able to update the common reference tree.
We display the files where the child differs from the first parent
first in black in the file list window, followed by the second parent
in blue, and so on using different colors for each parent (provided
you don't have more than 6 parents; if you do we cycle around).
Make searching in files changed faster, and fix some bugs.
We now kick off a single git-diff-tree -r --stdin and feed it all
the commit pairs we want to know about, instead of doing a separate
git-diff-tree invocation for each.

[PATCH] fetch/pull: short-hand notation for remote repositories.
Since pull and fetch are done often against the same remote
repository repeatedly, keeping the URL to pull from along with
the name of the head to use in $GIT_DIR/branches/$name makes a
lot of sense. Adopt that convention from Cogito, and try to be
compatible when possible; storing a partial URL and completing
it with a trailing path may not be understood by Cogito.
While we are at it, fix pulling a tag. Earlier, we updated only
refs/tags/$tag without updating FETCH_HEAD, and called
resolve-script using a stale (or absent) FETCH_HEAD.

"Files" matches the find string against each of the files modified
by each commit, and can do exact, case-ignoring or regexp matching.
"Pickaxe" uses git-diff-tree -S'string' and can only do exact
matching. I called it "pickaxe" rather than "find within patch"
since it only finds commits where the string is present in the child
but not the parents or vice versa, and "pickaxe" is what the author
of that feature calls it.

Now, not all projects can be as refined as Linux. Before the final 1.0
release, we went through fifteen 0.99 patchfiles, and pl14 alone went
through subreleases 'a' through 'z'. Now _that_ is a release process.
Not to mention the odd-ball releases, like 0.96c+
Sadly, in this day and age of RPM's etc, we have silly limitations, and
I cannot call this release '0.99pl5a or some such awe-inspiring name
just because "rpmbuild" is such a party pooper. So it's just 0.99.1.
Oh well. Aspiring to such greatness as the Linux release numbering is

git-daemon: re-organize code a bit for --inetd flag
Alexey Nezhdanov sent a patch that made git-daemon usable from inetd (ie
where inetd has already done the accept on the new connection, the fork,
and the setup of stdin/stdout). I wanted to organize the thing slightly
differently, though.
Split up "diff_format" into "format" and "line_termination".
This removes the separate "formats" for name and name-with-zero-
termination.
It also removes the difference between HUMAN and MACHINE formats, and
they both become DIFF_FORMAT_RAW, with the difference being just in the
line and inter-filename termination.
... and make git-diff-files use it too. This all _should_ make the
diffcore-pathspec.c phase unnecessary, since the diff'ers now all do the
path matching early interally.
Start using the partial tree reading in "git-diff-cache"
The reason I say "start using" is that we really should also limit the
index checking by name - now we limit the tree object accesses by name,
but we still check the whole index.
Make "git prune" use the "--full" flag to git-fsck-cache
It's too dangerous not to. We need to follow alternate object
directories etc, or we might say something is unreachable just because
we didn't look it up completely.
