- A new header file, git-compat-util.h, is introduced. This
looks at various NO_XXX and does necessary function name
replacements, equivalent of -Dstrcasestr=gitstrcasestr in the
Makefile.
- Those function name replacements are removed from the Makefile.

This patch provides a C implementation of the 'git' program and
introduces support for putting the git-* commands in a directory
of their own. It also saves some time on executing those commands
in a tight loop and it prints the currently available git commands
in a nicely formatted list.
The location of the GIT_EXEC_PATH (name discussion's closed, thank gods)
can be obtained by running
git --exec-path
which will hopefully give porcelainistas ample time to adapt their
heavy-duty loops to call the core programs directly and thus save
the extra fork() / execve() overhead, although that's not really
necessary any more.
The --exec-path value is prepended to $PATH, so the git-* programs
should Just Work without ever requiring any changes to how they call
other programs in the suite.
Some timing values for 10000 invocations of git-var >&/dev/null:
git.sh: 24.194s
git.c: 9.044s
git-var: 7.377s
The git-<tab><tab> behaviour can, along with the someday-to-be-deprecated
git-<command> form of invocation, be indefinitely retained by adding
the following line to one's .bash_profile or equivalent:
PATH=$PATH:$(git --exec-path)
Experimental libraries can be used by either setting the environment variable
GIT_EXEC_PATH, or by using
git --exec-path=/some/experimental/exec-path
Relative paths are properly grok'ed as exec-path values.

A while ago, a rename-detection limit logic was implemented as a
response to this thread:
http://marc.theaimsgroup.com/?l=git&m=112413080630175
where gitweb was found to be using a lot of time and memory to
detect renames on huge commits. git-diff family takes -l<num>
flag, and if the number of paths that are rename destination
candidates (i.e. new paths with -M, or modified paths with -C)
are larger than that number, skips rename/copy detection even
when -M or -C is specified on the command line.
This commit makes the rename detection limit easier to use. You
can have:
[diff]
renamelimit = 30
in your .git/config file to specify the default rename detection
limit. You can override this from the command line; giving 0
means 'unlimited':
git diff -M -l0
We might want to change the default behaviour, when you do not
have the configuration, to limit it to say 20 paths or so. This
would also help the diffstat generation after a big 'git pull'.

I think the original intention was to make CFLAGS overridable
from the make command line, but somehow we ended up accumulating
conditional makefile sections that wrongly appends values to
CFLAGs. These assignments do not work when the user actually
override them from the make command line!
DEFINES are handled the same way; it was seemingly overridable,
but the makefile sections had assignments, which meant
overriding it from the command line broke things.
This simplifies things by limiting the internal futzing to
ALL_CFLAGS, and by removing DEFINES altogether. Overriding
CFLAGS from the command line should start working with this
change.

==============
Ports
~~~~~
* Cygwin port [HPA].
* OpenBSD build [Merlyn and others].
Fixes
~~~~~
* clone request over git native protocol from a repository with
too many refs did not work; this has been fixed.
* git-daemon got safer for kernel.org use [HPA].
* Extended SHA1 parser was not enforcing uniqueness for
abbreviated SHA1; this has been fixed.
* http transport does not barf on funny characters in URL.
* The ref naming restrictions have been formalized and the
coreish refuses to create funny refs; we still need to audit
importers. See git-check-ref-format(1).
New Features and Commands
~~~~~~~~~~~~~~~~~~~~~~~~~
* .git/config file as a per-repository configuration mechanism,
and some commands understand it [Linus]. See
git(7).
* The core.filemode configuration item can be used to make us a
bit more FAT friendly. See git(7).
* The extended SHA1 notation acquired Peel-the-onion operator
^{type} and ^{}. See git-rev-parse(1).
* SVN importer [Matthias]. See git-svnimport(1).
* .git/objects/[0-9a-f]{2} directories are created on demand,
and removed when becomes empty after prune-packed [Linus].
* Filenames output from various commands without -z option are
quoted when they embed funny characters (TAB and LF) using
C-style quoting within double-quotes, to match the proposed
GNU diff/patch notation [me, but many people contributed in
the discussion].
* git-mv is expected to be a better replacement for git-rename.
While the latter has two parameter restriction, it acts more
like the regular 'mv' that can move multiple things to one
destinatino directory [Josef Weidendorfer].
* git-checkout can take filenames to revert the changes to
them. See git-checkout(1)
* The new program git-am is a replacement for git-applymbox that
has saner command line options and a bit easier to use when a
patch does not apply cleanly.
* git-ls-remote can show unwrapped onions using ^{} notation, to
help Cogito to track tags.
* git-merge-recursive backend can merge unrelated projects.
* git-clone over native transport leaves the result packed.
* git-http-fetch issues multiple requests in parallel when
underlying cURL library supports it [Nick and Daniel].
* git-fetch-pack and git-upload-pack try harder to figure out
better common commits [Johannes].
* git-read-tree -u removes a directory when it makes it empty.
* git-diff-* records abbreviated SHA1 names of original and
resulting blob; this sometimes helps to apply otherwise an
unapplicable patch by falling back to 3-way merge.
* git-format-patch now takes series of from..to rev ranges and
with '-m --stdout', writes them out to the standard output.
This can be piped to 'git-am' to implement cheaper
cherry-picking.
* git-tag takes '-u' to specify the tag signer identity [Linus].
* git-rev-list can take optional pathspecs to skip commits that
do not touch them (--dense) [Linus].
* Comes with new and improved gitk [Paulus and Linus].

git-name-rev tries to find nice symbolic names for commits. It does so by
walking the commits from the refs. When the symbolic name is ambiguous, the
following heuristic is applied: Try to avoid too many ~'s, and if two ambiguous
names have the same count of ~'s, take the one whose last number is smaller.
With "--tags", the names are derived only from tags.
With "--stdin", the stdin is parsed, and after every sha1 for which a name
could be found, the name is appended. (Try "git log | git name-rev --stdin".)

git-pack-objects can reuse pack files stored in $GIT_DIR/pack-cache

when upload-pack (called from git-daemon) is expected to receive
requests for the same set of objects many times (e.g full cloning
request of any project, or updates from the set of heads previous day
to the latest for a slow moving project).
Currently git-pack-objects does *not* keep pack files it creates for
reusing. It might be useful to add --update-cache option to it,

directory, and prune rarely used ones from it.

It supersedes git-rename by adding functionality to move multiple

The implementation renames multiple files, using the arguments from
the command line to produce an array of sources and destinations. In
a first pass, all requested renames are checked for errors, and
overwriting of existing files is only allowed with '-f'. The actual
renaming is done in a second pass. This ensures that any error

This makes the tree diff functionality independent of the "git-diff-tree"
program, by splitting the core functionality up into a library file.
This will be needed for when we teach git-rev-list to only follow a
specified set of pathnames, rather than the global revision history.
Most of it is a fairly straightforward code move, but it also involves
some calling convention cleanup, and moving some of the static variables
from diff-tree.c into the options structure.
The actual tree change callback routines also become paramterized by the
diff_options structure, allowing the library functionality to do something
else than just show the diff on stdout.

that you don't have to use the GIT_COMMITTER_EMAIL environment variable

you can link against libgit.a and get the git environment without having

This is a first cut at a very simple parser for a git config file.
The format of the file is a simple ini-file like thing, with simple
variable/value pairs. You can (and should) make the variables have a
simple single-level scope, ie a valid file looks something like this:
#
# This is the config file, and
# a '#' or ';' character indicates
# a comment
#
; core variables
[core]
; Don't trust file modes
filemode = false
; Our diff algorithm
[diff]
external = "/usr/local/bin/gnu-diff -u"
renames = true
which parses into three variables: "core.filemode" is associated with the
string "false", and "diff.external" gets the appropriate quoted value.
Right now we only react to one variable: "core.filemode" is a boolean that
decides if we should care about the 0100 (user-execute) bit of the stat
information. Even that is just a parsing demonstration - this doesn't
actually implement that st_mode compare logic itself.
Different programs can react to different config options, although they
should always fall back to calling "git_default_config()" on any config
option name that they don't recognize.

This is a careful version of the script stuff that currently just
blindly writes HEAD with a new value.
You can use
git-update-ref HEAD <newhead>
or
git-update-ref HEAD <newhead> <oldhead>
where the latter version verifies that the old value of HEAD matches
oldhead.
It basically allows a "ref" file to be a symbolic pointer to another ref
file by starting with the four-byte header sequence of "ref:".
More importantly, it allows the update of a ref file to follow these
symbolic pointers, whether they are symlinks or these "regular file
symbolic refs".
NOTE! It follows _real_ symlinks only if they start with "refs/":
otherwise it will just try to read them and update them as a regular file
(ie it will allow the filesystem to follow them, but will overwrite such a
symlink to somewhere else with a regular filename).
In general, using
git-update-ref HEAD "$head"
should be a _lot_ safer than doing
echo "$head" > "$GIT_DIR/HEAD"
both from a symlink following standpoint _and_ an error checking
standpoint. The "refs/" rule for symlinks means that symlinks that point
to "outside" the tree are safe: they'll be followed for reading but not
for writing (so we'll never write through a ref symlink to some other
tree, if you have copied a whole archive by creating a symlink tree).

I really wanted to try this out, instead of asking for an adjustment

The new command 'git merge' takes the current head and one or more
remote heads, with the commit log message for the automated case.
If the heads being merged are simple fast-forwards, it acts the
same way as the current 'git resolve'. Otherwise, it tries
different merge strategies and takes the result from the one that
succeeded auto-merging, if there is any.
If no merge strategy succeeds auto-merging, their results are
evaluated for number of paths needed for hand resolving, and the
one with the least number of such paths is left in the working
tree. The user is asked to resolve them by hand and make a
commit manually.
The calling convention from the 'git merge' driver to merge
strategy programs is very simple:
- A strategy program is to be called 'git-merge-<strategy>'.
- They take input of this form:
<common1> <common2> ... '--' <head> <remote1> <remote2>...
That is, one or more the common ancestors, double dash, the
current head, and one or more remote heads being merged into
the current branch.
- Before a strategy program is called, the working tree is
matched to the current <head>.
- The strategy program exits with status code 0 when it
successfully auto-merges the given heads. It should do
update-cache for all the merged paths when it does so -- the
index file will be used to record the merge result as a
commit by the driver.
- The strategy program exits with status code 1 when it leaves
conflicts behind. It should do update-cache for all the
merged paths that it successfully auto-merged, and leave the
cache entry in the index file as the same as <head> for paths
it could not auto-merge, and leave its best-effort result
with conflict markers in the working tree when it does so.
- The strategy program exists with status code other than 0 or
1 if it does not handle the given merge at all.
As examples, this commit comes with merge strategies based on
'git resolve' and 'git octopus'.

The reverse patch application using "git apply" sometimes is too
rigid. Since the user would get used to resolving conflicting merges
by hand during the normal merge experience, using the same machinery
would be more helpful rather than just giving up.
Cherry-picking and reverting are essentially the same operation.
You pick one commit, and apply the difference that commit introduces
to its own commit ancestry chain to the current tree. Revert applies
the diff in reverse while cherry-pick applies it forward. They share
the same logic, just different messages and merge direction.

The 'git show-branches' command turns out to be reasonably useful,

while enhancing it a bit more.
- Unlike show-branches, it can take --heads (show me all my
heads), --tags (show me all my tags), or --all (both).
- It can take --more=<number> to show beyond the merge-base.
- It shows the short name for each commit in the extended SHA1
syntax.
- It can find merge-base for more than two heads.
Examples:
$ git show-branch --more=6 HEAD
is almost the same as "git log --pretty=oneline --max-count=6".
$ git show-branch --merge-base master mhf misc
finds the merge base of the three given heads.
$ git show-branch master mhf misc
shows logs from the top of these three branch heads, up to their
common ancestor commit is shown.
$ git show-branch --all --more=10
is poor-man's gitk, showing all the tags and heads, and
going back 10 commits beyond the merge base of those refs.

This patch renames COPTS to CFLAGS, because it's COPTS that was user

Defines are added to DEFINES. Since ALL_CFLAGS is recursively expanded,
it uses the final value of DEFINES.
Implicit rules are made explicit since the implicit rules use CFLAGS

This adds a new "git bisect" command.
- "git bisect start"
start bisection search.
- "git bisect bad <rev>"
mark some version known-bad (if no arguments, then current HEAD)
- "git bisect good <revs>..."
mark some versions known-good (if no arguments, then current HEAD)
- "git bisect reset <branch>"
done with bisection search and go back to your work (if
no arguments, then "master").
The way you use it is:
git bisect start
git bisect bad # Current version is bad
git bisect good v2.6.13-rc2 # v2.6.13-rc2 was the last version
# tested that was good
When you give at least one bad and one good versions, it will
bisect the revision tree and say something like:
Bisecting: 675 revisions left to test after this
and check out the state in the middle. Now, compile that kernel, and boot
it. Now, let's say that this booted kernel works fine, then just do
git bisect good # this one is good
which will now say
Bisecting: 337 revisions left to test after this
and you continue along, compiling that one, testing it, and depending on
whether it is good or bad, you say "git bisect good" or "git bisect bad",
and ask for the next bisection.
Until you have no more left, and you'll have been left with the first bad
kernel rev in "refs/bisect/bad".
Oh, and then after you want to reset to the original head, do a
git bisect reset
to get back to the master branch, instead of being in one of the bisection
branches ("git bisect start" will do that for you too, actually: it will
reset the bisection state, and before it does that it checks that you're
not using some old bisection branch).
Not really any harder than doing series of "quilt push" and "quilt pop",
now is it?
[jc: This patch is a rework based on what Linus posted to the
list. The changes are:
- The original introduced four separate commands, which was
three too many, so I merged them into one with subcommands.
- Since the next thing you would want to do after telling it
"bad" and "good" is always to bisect, this version does it
automatically for you.
- I think the termination condition was wrong. The original
version checked if the set of revisions reachable from next
bisection but not rechable from any of the known good ones
is empty, but if the current bisection was a bad one, this
would not terminate, so I changed it to terminate it when
the set becomes a singleton or empty.
- Removed the use of shell array variable.
