since it's often hidden by a lot of error messages.
Add an extra line which prints the name of the failed patch just

contrib: add 'git difftool' for launching common merge tools

'git difftool' is a git command that allows you to compare and edit files
between revisions using common merge tools. 'git difftool' does what
'git mergetool' does but its use is for non-merge situations such as
when preparing commits or comparing changes against the index.
It uses the same configuration variables as 'git mergetool' and
provides the same command-line interface as 'git diff'.

http-push: when making directories, have a trailing slash in the path name

The function lock_remote() sends MKCOL requests to make leading
directories; However, if it does not put a forward slash '/' at the end of
the path, the server sends a 301 redirect.

By leaving the '/' in place, we can avoid this additional step.

Incidentally, at least one version of Curl (7.16.3) does not resend
credentials when it follows a 301 redirect, so this commit also fixes
a bug.

expand --pretty=format color options

Currently, the only colors available to --pretty=format
users are red, green, and blue. Rather than expand it with a
few new colors, this patch makes the usual config color
syntax available, including more colors, backgrounds, and
attributes.

Because colors are no longer bounded to a single word (e.g.,
%Cred), this uses a more advanced syntax that features a
beginning and end delimiter (but the old syntax still
works). So you can now do:

git log --pretty=tformat:'%C(yellow)%h%C(reset) %s'

to emulate --pretty=oneline, or even

git log --pretty=tformat:'%C(cyan magenta bold)%s%C(reset)'

if you want to relive the awesomeness of 4-color CGA.

color: make it easier for non-config to parse color... Jeff King Sat, 17 Jan 2009 15:32:30 +0000 (10:32 -0500)

color: make it easier for non-config to parse color specs

We have very featureful color-parsing routines which are
used for color.diff.* and other options. Let's make it
easier to use those routines from other parts of the code.

This patch adds a color_parse_mem() helper function which
takes a length-bounded string instead of a NUL-terminated
one. While the helper is only a few lines long, it is nice
to abstract this out so that:

- callers don't forget to free() the temporary buffer

- right now, it is implemented in terms of color_parse().
But it would be more efficient to reverse this and
implement color_parse in terms of color_parse_mem.

This also changes the error string for an invalid color not
to mention the word "config", since it is not always
appropriate (and when it is, the context is obvious since
the offending config variable is given).

Finally, while we are in the area, we clean up the parameter
names in the declaration of color_parse; the var and value
parameters were reversed from the actual implementation.

builtin-commit.c: do not remove COMMIT_EDITMSG

git-commit tries to remove the file ./COMMIT_EDITMSG instead of
$GIT_DIR/COMMIT_EDITMSG after commit preparation (e.g. running
hooks, launching editor).
This behavior exists since f5bbc3225c4b07 "Port git commit to C".

Some test cases (e.g. t/t7502-commit.sh) rely on the existence of
$GIT_DIR/COMMIT_EDITMSG after committing and, I guess, many people
are used to it. So it is best not to remove it.

This patch just removes the removal of COMMIT_EDITMSG.

Move run_hook() from builtin-commit.c into run-command.c (libgit)

A function that runs a hook is used in several Git commands.
builtin-commit.c has the one that is most general for cases without
piping. The one in builtin-gc.c prints some useful warnings.
This patch moves a merged version of these variants into libgit and
lets the other builtins use this libified run_hook().

The run_hook() function used in receive-pack.c feeds the standard
input of the pre-receive or post-receive hooks. This function is
renamed to run_receive_hook() because the libified run_hook() cannot
handle this.

since then "<foo" becomes a word (and "bar>" doesn't!) even though the

color-words: take an optional regular expression describing words

In some applications, words are not delimited by white space. To
allow for that, you can specify a regular expression describing
what makes a word with

git diff --color-words='[A-Za-z0-9]+'

Note that words cannot contain newline characters.

As suggested by Thomas Rast, the words are the exact matches of the
regular expression.

Note that a regular expression beginning with a '^' will match only
a word at the beginning of the hunk, not a word at the beginning of
a line, and is probably not what you want.

color-words: change algorithm to allow for 0-character... Johannes Schindelin Sat, 17 Jan 2009 16:29:44 +0000 (17:29 +0100)

color-words: change algorithm to allow for 0-character word boundaries

Up until now, the color-words code assumed that word boundaries are
identical to white space characters.

Therefore, it could get away with a very simple scheme: it copied the
hunks, substituted newlines for each white space character, called
libxdiff with the processed text, and then identified the text to
output by the offsets (which agreed since the original text had the
same length).

This code was ugly, for a number of reasons:

- it was impossible to introduce 0-character word boundaries,

- we had to print everything word by word, and

- the code needed extra special handling of newlines in the removed part.

Fix all of these issues by processing the text such that

- we build word lists, separated by newlines,

- we remember the original offsets for every word, and

- after calling libxdiff on the wordlists, we parse the hunk headers, and
find the corresponding offsets, and then

- we print the removed/added parts in one go.

The pre and post samples in the test were provided by Santi Béjar.

Note that there is some strange special handling of hunk headers where
one line range is 0 due to POSIX: in this case, the start is one too
low. In other words a hunk header '@@ -1,0 +2 @@' actually means that
the line must be added after the _second_ line of the pre text, _not_
the first.

Some user environments may enable this setting in the interactive shell.

In any context where the completion functions access an undefined

is a reasonable way to code the function, as it silences the undefined

fix handling of multiple untracked files for git mv -k

The "-k" option to "git mv" should allow specifying multiple untracked

rebase -i: learn to rebase root commit

Teach git-rebase -i a new option --root, which instructs it to rebase
the entire history leading up to <branch>. This is mainly for
symmetry with ordinary git-rebase; it cannot be used to edit the root
commit in-place (it requires --onto <newbase>). Commits that already
exist in <newbase> are skipped.

In the normal mode of operation, this is fairly straightforward. We
run cherry-pick in a loop, and cherry-pick has supported picking the
root commit since f95ebf7 (Allow cherry-picking root commits,
2008-07-04).

In --preserve-merges mode, we track the mapping from old to rewritten
commits and use it to update the parent list of each commit. In this
case, we define 'rebase -i -p --root --onto $onto $branch' to rewrite
the parent list of all root commit(s) on $branch to contain $onto
instead.

rebase: learn to rebase root commit

Teach git-rebase a new option --root, which instructs it to rebase the

to be skipped. (Normal operation skips commits that already exist in
<upstream> instead.)

One possible use-case is with git-svn: suppose you start hacking
(perhaps offline) on a new project, but later notice you want to
commit this work to SVN. You will have to rebase the entire history,
including the root commit, on a (possibly empty) commit coming from
git-svn, to establish a history connection. This previously had to
be done by cherry-picking the root commit manually.

Cleanup of unused symcache variable inside diff-lib.cKjetil Barvik Sun, 11 Jan 2009 18:36:42 +0000 (19:36 +0100)

Cleanup of unused symcache variable inside diff-lib.c

Commit c40641b77b0274186fd1b327d5dc3246f814aaaf, 'Optimize
symlink/directory detection' by Linus Torvalds, removed the 'char
*symcache' parameter to the has_symlink_leading_path() function. This
made all variables currently named 'symcache' inside diff-lib.c
unnecessary.

This also let us throw away the 'struct oneway_unpack_data', and
instead directly use the 'struct rev_info *revs' member, which
was the only member left after removal of the 'symcache[] array'
member. The 'struct oneway_unpack_data' was introduced by the
following commit:

Wrap inflate and other zlib routines for better error reporting

R. Tyler Ballance reported a mysterious transient repository corruption;
after much digging, it turns out that we were not catching and reporting
memory allocation errors from some calls we make to zlib.

This one _just_ wraps things; it doesn't do the "retry on low memory
error" part, at least not yet. It is an independent issue from the
reporting. Some of the errors are expected and passed back to the caller,
but we die when zlib reports it failed to allocate memory for now.

format-patch: show patch text for the root commit

Even without --root specified, if the range given on the command line
happens to include a root commit, we should include its patch text in the
output.

This fix deliberately ignores log.showroot configuration variable because
"format-patch" and "log -p" can and should behave differently in this
case, as the former is about exporting a part of your history in a form
that is replayable elsewhere and just giving the commit log message
without the patch text does not make any sense for that purpose.

Noticed and fix originally attempted by Nathan W. Panike; credit goes to
Alexander Potashev for injecting sanity to my initial (broken) fix that
used the value from log.showroot configuration, which was misguided.

combination of filters, except --commit-hook that must used

Resurrect "git apply --flags -" to read from the standard input

The previous "parse-opt"ification broke git-apply reading from the
standard input. "git apply A - C <B" is supposed to read patches from
files A, B and C in this order.

Before "parse-opt"ification, we used be able to:

git apply --stat - --apply <A B

to read the patch from file A, showing only the diffstat, and then read the
patch from file B, showing the diffstat and actually applying it. Even
with this fix we cannot do that anymore, but that is so crazy use case I
do not think anybody sane relied on such a broken behaviour.

$ time git grep -F grep v1.6.1 >/dev/null

real 0m0.170s

With the patch:

$ time git grep grep v1.6.1 >/dev/null

real 0m0.173s
user 0m0.000s
sys 0m0.000s

The difference is much smaller on Linux, but still measurable.

grep -w: forward to next possible position after reject... René Scharfe Fri, 9 Jan 2009 23:08:40 +0000 (00:08 +0100)

grep -w: forward to next possible position after rejected match

grep -w accepts matches between non-word characters, only. If a match
from regexec() doesn't meet this criteria, grep continues its search
after the first character of that match.

We can be a bit smarter here and skip all positions that follow a word
character first, as they can't match our criteria. This way we can
consume characters quite cheaply and don't need to special-case the
handling of the beginning of a line.

Here's a contrived example command on msysgit (best of five runs):

$ time git grep -w ...... v1.6.1 >/dev/null

real 0m1.611s
user 0m0.000s
sys 0m0.015s

With the patch it's quite a bit faster:

$ time git grep -w ...... v1.6.1 >/dev/null

real 0m1.179s
user 0m0.000s
sys 0m0.015s

More common search patterns will gain a lot less, but it's a nice clean
up anyway.
