Subject: Port git commit to C.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This makes git commit a builtin and moves git-commit.sh to
contrib/examples.  This also removes the git-runstatus
helper, which was mostly just a git-status.sh implementation detail.

Subject: builtin-commit: fix reflog message generation

Instead of strdup()ing, we can just reuse the buffer in which the
commit message is stored, and which is supposed to hold the reflog
message anyway.

Subject: builtin-commit: Refresh cache after adding files.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We have promised our users that after running git-status or
git-commit the index will be refreshed for a long time since
these commands were introduced.  Do refresh the index before
writing it out to keep the promise.

Subject: git status: show relative paths when run in a subdirectory

To show the relative paths, the function formerly called quote_crlf()
(now called quote_path()) takes the prefix as an additional argument.

While at it, the static buffers were replaced by strbufs.

Subject: builtin-commit: fix --signoff

The Signed-off-by: line contained a spurious timestamp.  The reason was
a call to git_committer_info(1), which automatically added the
timestamp.

Instead, fmt_ident() was taught to interpret an empty string for the
date (as opposed to NULL, which still triggers the default behavior)
as "do not bother with the timestamp", and builtin-commit.c uses it.

Subject: builtin-commit --s: add a newline if the last line was not a S-o-b

The rule is this: if the last line already contains the sign off by the
current committer, do nothing.  If it contains another sign off, just
add the sign off of the current committer.  If the last line does not
contain a sign off, add a new line before adding the sign off.

We're guaranteeing the user that the index will be stat-clean after
git commit. Thus, we need to call refresh_cache() for the user index too,
in the 'git commit <paths>' case.

Subject: builtin-commit: fix partial-commit support

When making a partial-commit, we need to prepare two index
files, one to be used to write out the tree to be committed
(temporary index) and the other to be used as the index file
after the commit is made.

The temporary index needs to be initialized to HEAD and then all
the named paths on the command line need to be staged on top of
the index.  For this, running add_files_to_cache() that compares
what is in the index and the paths given from the command line
is not enough -- the comparison will miss the paths that the
user previously ran "git add" to the index since the HEAD
because the index reset to the HEAD would not know about them.
The index file needs to get the same modification done when
preparing the temporary index as described above.

This implementation mimics the behaviour of the scripted
version of git-commit.  It first runs overlay_tree_on_cache(),
which was stolen from ls-files with the earlier change, to get
the list of paths that the user can potentially mean, and then
uses pathspec_match() to find which ones the user meant.  This
list of paths is used to update both the temporary and the real
index file.

Additional fixes are:

 - read the index file after pre-commit hook returns, as the
   hook can modify it to affect the contents of the commit.

 - remove the temporary index file .git/next-index-* after
   commit is done or aborted.

 - run post-commit hook with the real index file to be used
   after the commit (previously it gave the temporary commit if
   a partial commit was made).

 - resurrect the safety mechanism to refuse partial commits
   during a merge to match the scripted version.

Subject: add -i: Fix running from a subdirectory

This fixes the pathspec interactive_add() passes to the underlying
git-add--interactive helper.  When the command was run from a
subdirectory, cmd_add() already has gone up to the toplevel of the work
tree, and the helper will be spawned from there.  The pathspec given on
the command line from the user needs to be adjusted for this.

This adds "validate_pathspec()" function in the callchain, but it does
not validate yet.  The function can be changed to barf if there are
unmatching pathspec given by the user, but that is not strictly
necessary.

These are three types of cleanups here:

  1. remove newline from die message (die/report adds it
     already)
  2. typo: s/merger/merge/
  3. the old "* no commit message?  aborting commit." is now
     prepended with "fatal: ", making the asterisk look a
     little funny. Let's just remove it.

Introduce fmt_name() specifically meant for formatting the name and
email pair, to add signed-off-by value.  This reverts parts of
13208572fbe8838fd8835548d7502202d1f7b21d (builtin-commit: fix --signoff)
so that an empty datestamp string given to fmt_ident() by mistake will
error out as before.

Subject: Make git status usage say git status instead of git commit

git status shares the same usage information as git commit since it
shows what would be committed if the same options are given.  However,
when displaying the usage information for git status it should say it
is for git status not git commit.

Subject: git-commit: Allow to amend a merge commit that does not change the
 tree

Normally, it should not be allowed to generate an empty commit. A merge
commit generated with git 'merge -s ours' does not change the tree (along
the first parent), but merges are not "empty" even if they do not change
the tree. Hence, we should be careful not to forbid this case.

Subject: git-commit --allow-empty

It does not usually make sense to record a commit that has the exact
same tree as its sole parent commit and that is why git-commit prevents
you from making such a mistake, but when data from foreign scm is
involved, it is a different story.  We are equipped to represent such an
(perhaps insane, perhaps by mistake, or perhaps done on purpose) empty
change, and it is better to represent it bypassing the safety valve for
native use.

This is primarily for use by foreign scm interface scripts.

to skip over the commit-msg hook as well. This brings the behaviour

The old git-commit.sh script allowed the commit-msg hook to not only
prevent a commit from proceding, but also to edit the commit message
on the fly and allow it to proceed. So here we teach builtin-commit
to do the same.

This is based on Wincent's patch, but redone with a clarified logic.

Date: Sat, 8 Dec 2007 17:32:08 -0800
Subject: Re-fix "builtin-commit: fix --signoff"

An earlier fix to the said commit was incomplete; it mixed up the
meaning of the flag parameter passed to the internal fmt_ident()
function, so this corrects it.

git_author_info() and git_committer_info() can be told to issue a
warning when no usable user information is found, and optionally can be
told to error out.  Operations that actually use the information to
record a new commit or a tag will still error out, but the caller to
leave reflog record will just silently use bogus user information.

Not warning on misconfigured user information while writing a reflog
entry is somewhat debatable, but it is probably nicer to the users to
silently let it pass, because the only information you are losing is who
checked out the branch.

 * git_author_info() and git_committer_info() used to take 1 (positive
   int) to error out with a warning on misconfiguration; this is now
   signalled with a symbolic constant IDENT_ERROR_ON_NO_NAME.

 * These functions used to take -1 (negative int) to warn but continue;
   this is now signalled with a symbolic constant IDENT_WARN_ON_NO_NAME.

 * fmt_ident() function implements the above error reporting behaviour
   common to git_author_info() and git_committer_info().  A symbolic
   constant IDENT_NO_DATE can be or'ed in to the flag parameter to make
   it return only the "Name <email@address.xz>".

 * fmt_name() is a thin wrapper around fmt_ident() that always passes
   IDENT_ERROR_ON_NO_NAME and IDENT_NO_DATE.

Subject: git-commit: squelch needless message during an empty merge

When recording a merge that conflicted and ends up in no changes after
manual resolution, commit callchain looked like this:

	cmd_commit() ->
            prepare_log_message() ->
                run_status() ->
		    wt_status_print()

This invocation of run_status() is asked to find out if there is a
committable change, but it unconditionally gave instructions such as
"use git-add" at the same time.  When in merge, we do allow an empty
change to be recorded, so after showing this message the code still went
ahead and made a commit.

This introduces "nowarn" parameter to run_status() to avoid these
useless messages.  If we are not allowed to create an empty commit, we
already call run_status() again in the original codepath, and the
message will be shown from that call anyway.

Subject: commit: allow --amend to reuse message from another commit

After tentatively applying a patch from a contributor, you can get a
replacement patch with corrected code and unusable commit log message.
In such a case, this sequence ought to give you an editor based on the
message in the earlier commit, to let you describe an incremental
improvement:

    git reset --hard HEAD^ ;# discard the earlier one
    git am <corrected-patch
    git commit --amend -c HEAD@{1}

Unfortunately, --amend insisted reusing the message from the commit
being amended, ignoring the -c option.  This corrects it.

Subject: fix git commit --amend -m "new message"

The prepare_log_message() function serves two purposes:

 - Prepares the commit log message template, to be given to the end
   user;

 - Return true if there is something committable;

7168624c3530d8c7ee32f930f8fb2ba302b9801f (Do not generate full commit
log message if it is not going to be used) cheated to omit the former
when we know the log message template is not going to be used.  However,
its replacement logic to see if there is something committable was
botched.  When amending, it should compare the index with the parent of
the HEAD, not the current HEAD.  Otherwise you cannot run --amend to
fix only the message without changing the tree.

The flag no_edit meant "we have got final message from the user

use_editor and reverse the logic everywhere.

Subject: Allow selection of different cleanup modes for commit messages

Although we traditionally stripped away excess blank lines, trailing
whitespaces and lines that begin with "#" from the commit log message,
sometimes the message just has to be the way user wants it.

For instance, a commit message template can contain lines that begin with
"#", the message must be kept as close to its original source as possible
if you are converting from a foreign SCM, or maybe the message has a shell
script including its comments for future reference.

The cleanup modes are default, verbatim, whitespace and strip. The
default mode depends on if the message is being edited and will either
strip whitespace and comments (if editor active) or just strip the
whitespace (for where the message is given explicitely).

Subject: Fix performance regression for partial commits

When running "git commit paths" to create a partial commit, we
used to carefully build the temporary index so that we do not
lose the cached stat information.  The rewrite of the command in
C lost it by carelessly using read_tree().

This resurrects the earlier behaviour to keep the cached stat
information as much as possible by using one-tree merge logic.

2888605c649ccd423232161186d72c0e6c458a48 (builtin-commit: fix
partial-commit support) mindlessly cut and pasted from
builtin-ls-files.c, and included a part that was meant to
exclude redundant path after "ls-files --with-tree" overlayed
the HEAD commit on top of the index.  This logic does not apply
to what git-commit does and should not have been copied, even
though it would not hurt.

Subject: Revert "builtin-commit.c: remove useless check added by faulty cut
 and paste"

This reverts commit 16335fdd7ace78a8285ba25fd7a81177a48e7c9b.

We are calling overlay_tree_on_cache() which does use CE_UPDATE
flag to mark duplicated entries, which is the same as the
codepath in git-ls-files with its --with-tree option.

Because the pathname ce->name is given to path_list_insert()
which does not allow duplicates, there is no breakage either way
from the correctness point of view in this codepath, unlike the
one in ls-files.  But avoiding unnecessary processing with a
single bit check is certainly better.

Subject: git-commit: fix double close(2) that can close a wrong file
 descriptor

The codepath to prepare index files for the temporary and next
index file was closing file descriptor it obtained from the
lockfile API by hand, without letting the API know that the fd
should not be doubly closed.

This is not usually a problem (except it may get EBADFD) but if
we opened another fd for an entirely unrelated purpose (say, an
fd used to mmap a packfile) between the time we close the fd to
the index file and the time we commit or rollback the lockfile
(causing it to also try closing the recorded fd), the lockfile
API will close an incorrect file descriptor that is still used
for an entirely unrelated purpose.

There's four close(fd) calls in prepare_index() and they're all
incorrect.  The open fd's are cleaned up in rollback_index_files() and
shouldn't be closed manually.  The patch below gets rid of the extra
close() calls and should fix the problem.

When creating the commit object, be a whole lot more careful about making
sure that the parent lines really are valid parent lines. Check things
like MERGE_HEAD having proper SHA1 lines in it, and double-check that all
the parents exist and are actually commits.

Subject: Improve use of lockfile API

Remove remaining double close(2)'s.  i.e. close() before
commit_locked_index() or commit_lock_file().

From 7a51ed66f653c248993b3c4a61932e47933d835e Mon Sep 17 00:00:00 2001
From: Linus Torvalds <torvalds@linux-foundation.org>
Date: Mon, 14 Jan 2008 16:03:17 -0800
Subject: Make on-disk index representation separate from in-core one

This converts the index explicitly on read and write to its on-disk
format, allowing the in-core format to contain more flags, and be
simpler.

In particular, the in-core format is now host-endian (as opposed to the
on-disk one that is network endian in order to be able to be shared
across machines) and as a result we can dispense with all the
htonl/ntohl on accesses to the cache_entry fields.

This will make it easier to make use of various temporary flags that do
not exist in the on-disk format.

Subject: git-commit: exit non-zero if we fail to commit the index

In certain rare cases, the creation of the commit object
and update of HEAD can succeed, but then installing the
updated index will fail. This is most likely caused by a
full disk or exceeded disk quota. When this happens the
new index file will be removed, and the repository will
be left with the original now-out-of-sync index. The
user can recover with a "git reset HEAD" once the disk
space issue is resolved.

We should detect this failure and offer the user some
helpful guidance.

The scripted version might not have handled this correctly
either, but the version rewritten in C definitely does not grok
this and complains $tag is not a commit object.

Subject: git-commit: Refactor creation of log message.

This patch moves the code of run_commit, up to writing the trees, editing
the message and running the commit-msg hook to prepare_log_message.  It also
renames the latter to prepare_to_commit.

This simplifies a little the code for the next patch.

Subject: git-commit: add a prepare-commit-msg hook

The prepare-commit-msg hook is run whenever a "fresh" commit message
is prepared, just before it is shown in the editor (if it is).
Its purpose is to modify the commit message in-place.

It takes one to three parameters.  The first is the name of the file that
the commit log message.  The second is the source of the commit message,
and can be: "message" (if a -m or -F option was given); "template" (if a
-t option was given or the configuration option commit.template is set);
"merge" (if the commit is a merge or a .git/MERGE_MSG file exists);
"squash" (if a .git/SQUASH_MSG file exists); or "commit", followed by
a commit SHA1 as the third parameter (if a -c, -C or --amend option
was given).

If its exit status is non-zero, git-commit will abort.  The hook is
not suppressed by the --no-verify option, so it should not be used
as a replacement for the pre-commit hook.

The sample prepare-commit-msg comments out the `Conflicts:` part of
a merge's commit message; other examples are commented out, including
adding a Signed-off-by line at the bottom of the commit messsage,
that the user can then edit or discard altogether.

+prepare-commit-msg
+------------------
+
+This hook is invoked by `git-commit` right after preparing the
+default log message, and before the editor is started.
+
+It takes one to three parameters.  The first is the name of the file
+that the commit log message.  The second is the source of the commit
+message, and can be: `message` (if a `\-m` or `\-F` option was
+given); `template` (if a `\-t` option was given or the
+configuration option `commit.template` is set); `merge` (if the
+commit is a merge or a `.git/MERGE_MSG` file exists); `squash`
+(if a `.git/SQUASH_MSG` file exists); or `commit`, followed by
+a commit SHA1 (if a `\-c`, `\-C` or `\--amend` option was given).
+
+If the exit status is non-zero, `git-commit` will abort.
+
+The purpose of the hook is to edit the message file in place, and
+it is not suppressed by the `\--no-verify` option.  A non-zero exit
+means a failure of the hook and aborts the commit.  It should not
+be used as replacement for pre-commit hook.

Subject: Allow callers of unpack_trees() to handle failure

Return an error from unpack_trees() instead of calling die(), and exit
with an error in read-tree, builtin-commit, and diff-lib. merge-recursive
already expected an error return from unpack_trees, so it doesn't need to
be changed. The merge function can return negative to abort.

This will be used in builtin-checkout -m.

Subject: builtin-commit: remove .git/SQUASH_MSG upon successful commit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After doing a merge --squash, and commit afterwards, the commit message
template SQUASH_MSG in the git directory is not removed, which means that
the content of SQUASH_MSG is used as default commit message for all
subsequent commits.  So have git commit remove the file SQUASH_MSG from
the git directory upon a successful commit.

The problem was discovered by Frédéric Brière, reported through
 http://bugs.debian.org/464656

Subject: commit: discard index after setting up partial commit

There may still be some entries from the original index that
should be discarded before we show the status. In
particular, if a file was added in the index but not
included in the partial commit, it would still show up in
the status listing as staged for commit.

Ultimately the correct fix is to keep the two states in
separate index_state variables. Then we can avoid having
to reload the cache from the temporary file altogether, and
just point wt_status_print at the correct index.

Subject: Make 'unpack_trees()' take the index to work on as an argument

This is just a very mechanical conversion, and makes everybody set it to
'&the_index' before calling, but at least it makes it more explicit
where we work with the index.

The next stage would be to split that index usage up into a 'source' and
a 'destination' index, so that we can unpack into a different index than
we started out from.

From 34110cd4e394e3f92c01a4709689b384c34645d8 Mon Sep 17 00:00:00 2001
From: Linus Torvalds <torvalds@linux-foundation.org>
Date: Thu, 6 Mar 2008 18:12:28 -0800
Subject: Make 'unpack_trees()' have a separate source and destination index

We will always unpack into our own internal index, but we will take the
source from wherever specified, and we will optionally write the result
to a specified index (optionally, because not everybody even _wants_ any
result: the index diffing really wants to just walk the tree and index
in parallel).

This ends up removing a fair number more lines than it adds, for the
simple reason that we can now skip all the crud that tried to be
oh-so-careful about maintaining our position in the index as we were
traversing and modifying it.  Since we don't actually modify the source
index any more, we can just update the 'o->pos' pointer without worrying
about whether an index entry got removed or replaced or added to.

From 4da45bef56e1547eb6525015ada0fdfc01d8295b Mon Sep 17 00:00:00 2001
From: Junio C Hamano <gitster@pobox.com>
Date: Mon, 7 Apr 2008 17:11:34 -0700
Subject: log: teach "terminator" vs "separator" mode to "--pretty=format"

This attached patch introduces a single bit "use_terminator" in "struct
rev_info", which is normally false (i.e. most formats use separator
semantics) but by flipping it to true, you can ask for terminator
semantics just like oneline format does.

The function get_commit_format(), which is what parses "--pretty=" option,
now takes a pointer to "struct rev_info" and updates its commit_format and
use_terminator fields.  It used to return the value of type "enum
cmit_fmt", but all the callers assigned it to rev->commit_format.

There are only two cases the code turns use_terminator on.  Obviously, the
traditional oneline format (--pretty=oneline) is one of them, and the new
case is --pretty=tformat:... that acts like --pretty=format:... but flips
the bit on.

With this, "--pretty=tformat:%H %s" acts like --pretty=oneline.

from a few places, including builtin-commit.c (as part of the commentary in
the commit message template).

From d177cab0480f9fa172103071203fed1bff95f5c2 Mon Sep 17 00:00:00 2001
From: Linus Torvalds <torvalds@linux-foundation.org>
Date: Fri, 9 May 2008 09:11:43 -0700
Subject: Avoid some unnecessary lstat() calls

The commit sequence used to do

	if (file_exists(p->path))
		add_file_to_cache(p->path, 0);

where both "file_exists()" and "add_file_to_cache()" needed to do a
lstat() on the path to do their work.

This cuts down 'lstat()' calls for the partial commit case by two
for each path we know about (because we do this twice per path).

Just move the lstat() to the caller instead (that's all that
"file_exists()" really does), and pass the stat information down to the
add_to_cache() function.

This essentially makes 'add_to_index()' the core function that adds a path
to the index, getting the index pointer, the pathname and the stat
information as arguments. There are then shorthand helper functions that
use this core function:

 - 'add_to_cache()' is just 'add_to_index()' with the default index

 - 'add_file_to_cache/index()' is the same, but does the lstat() call
   itself, so you can pass just the pathname if you don't already have the
   stat information available.

So old users of the 'add_file_to_xyzzy()' are essentially left unchanged,
and this just exposes the more generic helper function that can take
existing stat information into account.

Subject: Provide git_config with a callback-data parameter

git_config() only had a function parameter, but no callback data
parameter.  This assumes that all callback functions only modify
global variables.

With this patch, every callback gets a void * parameter, and it is hoped
that this will help the libification effort.

Subject: commit --interactive: properly update the index before commiting
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When adding files through git commit --interactive, and 'quit'
afterwards, the message in the editor of the commit message indicates
that many (maybe all) files are deleted from the tree.  Dismissing that
and running git commit afterwards does the right thing.  This commit
fixes git commit --interactive to properly update the index before
commiting.

Subject: commit: drop duplicated parents

The scripted version of git-commit internally used git-commit-tree which
omitted duplicated parents given from the command line.  This prevented a
nonsensical octopus merge from getting created even when you said "git
merge A B" while you are already on branch A.

However, when git-commit was rewritten in C, this sanity check was lost.
This resurrects it.

Subject: Add an optional <mode> argument to commit/status -u|--untracked-files
 option

This lets you specify how you want untracked files to be listed.
The possible options are:

    normal - Show untracked files and directories
    all    - Show all untracked files

The 'all' mode is used, if the mode is not specified.

Subject: rerere: Separate libgit and builtin functions

This patch moves rerere()-related functions into a newly created
rerere.c file.
The setup_rerere() function is needed by both rerere() and cmd_rerere(),
so this function is moved to rerere.c and declared non-static (and "extern")
in newly created rerere.h file.

From 1b1dd23f2d6a707b7077cdf6bc6d4055bd0bfb7d Mon Sep 17 00:00:00 2001
From: Stephan Beyer <s-beyer@gmx.net>
Date: Sun, 13 Jul 2008 15:36:15 +0200
Subject: Make usage strings dash-less

When you misuse a git command, you are shown the usage string.
But this is currently shown in the dashed form.  So if you just
copy what you see, it will not work, when the dashed form
is no longer supported.

This patch makes git commands show the dash-less version.

For shell scripts that do not specify OPTIONS_SPEC, git-sh-setup.sh
generates a dash-less usage string now.

From c455c87c5cd42bbbe586b31cea1143132f3a39e4 Mon Sep 17 00:00:00 2001
From: Johannes Schindelin <Johannes.Schindelin@gmx.de>
Date: Mon, 21 Jul 2008 19:03:49 +0100
Subject: Rename path_list to string_list

The name path_list was correct for the first usage of that data structure,
but it really is a general-purpose string list.

$ perl -i -pe 's/path-list/string-list/g' $(git grep -l path-list)
$ perl -i -pe 's/path_list/string_list/g' $(git grep -l path_list)
$ git mv path-list.h string-list.h
$ git mv path-list.c string-list.c
$ perl -i -pe 's/has_path/has_string/g' $(git grep -l has_path)
$ perl -i -pe 's/path/string/g' string-list.[ch]
$ git mv Documentation/technical/api-path-list.txt \
	Documentation/technical/api-string-list.txt
$ perl -i -pe 's/strdup_paths/strdup_strings/g' $(git grep -l strdup_paths)

... and then fix all users of string-list to access the member "string"
instead of "path".

Documentation/technical/api-string-list.txt needed some rewrapping, too.

-path-list API
-=============
-
-The path_list API offers a data structure and functions to handle sorted
-and unsorted string lists.
-
-The name is a bit misleading, a path_list may store not only paths but
-strings in general.
-
-The caller:
-
-. Allocates and clears a `struct path_list` variable.
-
-. Initializes the members. You might want to set the flag `strdup_paths`
-  if the strings should be strdup()ed. For example, this is necessary
-  when you add something like git_path("..."), since that function returns
-  a static buffer that will change with the next call to git_path().
-+
-If you need something advanced, you can manually malloc() the `items`
-member (you need this if you add things later) and you should set the
-`nr` and `alloc` members in that case, too.
-
-. Adds new items to the list, using `path_list_append` or `path_list_insert`.
-
-. Can check if a string is in the list using `path_list_has_path` or
-  `unsorted_path_list_has_path` and get it from the list using
-  `path_list_lookup` for sorted lists.
-
-. Can sort an unsorted list using `sort_path_list`.
-
-. Finally it should free the list using `path_list_clear`.
-
-Example:
-
-----
-struct path_list list;
-int i;
-
-memset(&list, 0, sizeof(struct path_list));
-path_list_append("foo", &list);
-path_list_append("bar", &list);
-for (i = 0; i < list.nr; i++)
-	printf("%s\n", list.items[i].path)
-----
-
-NOTE: It is more efficient to build an unsorted list and sort it
-afterwards, instead of building a sorted list (`O(n log n)` instead of
-`O(n^2)`).
-+
-However, if you use the list to check if a certain string was added
-already, you should not do that (using unsorted_path_list_has_path()),
-because the complexity would be quadratic again (but with a worse factor).
-
-Functions
----------
-
-* General ones (works with sorted and unsorted lists as well)
-
-`print_path_list`::
-
-	Dump a path_list to stdout, useful mainly for debugging purposes. It
-	can take an optional header argument and it writes out the
-	string-pointer pairs of the path_list, each one in its own line.
-
-`path_list_clear`::
-
-	Free a path_list. The `path` pointer of the items will be freed in case
-	the `strdup_paths` member of the path_list is set. The second parameter
-	controls if the `util` pointer of the items should be freed or not.
-
-* Functions for sorted lists only
-
-`path_list_has_path`::
-
-	Determine if the path_list has a given string or not.
-
-`path_list_insert`::
-
-	Insert a new element to the path_list. The returned pointer can be handy
-	if you want to write something to the `util` pointer of the
-	path_list_item containing the just added string.
-+
-Since this function uses xrealloc() (which die()s if it fails) if the
-list needs to grow, it is safe not to check the pointer. I.e. you may
-write `path_list_insert(...)->util = ...;`.
-
-`path_list_lookup`::
-
-	Look up a given string in the path_list, returning the containing
-	path_list_item. If the string is not found, NULL is returned.
-
-* Functions for unsorted lists only
-
-`path_list_append`::
-
-	Append a new string to the end of the path_list.
-
-`sort_path_list`::
-
-	Make an unsorted list sorted.
-
-`unsorted_path_list_has_path`::
-
-	It's like `path_list_has_path()` but for unsorted lists.
-+
-This function needs to look through all items, as opposed to its
-counterpart for sorted lists, which performs a binary search.
-
-Data structures
----------------
-
-* `struct path_list_item`
-
-Represents an item of the list. The `path` member is a pointer to the
-string, and you may use the `util` member for any purpose, if you want.
-
-* `struct path_list`
-
-Represents the list itself.
-
-. The array of items are available via the `items` member.
-. The `nr` member contains the number of items stored in the list.
-. The `alloc` member is used to avoid reallocating at every insertion.
-  You should not tamper with it.
-. Setting the `strdup_paths` member to 1 will strdup() the strings
-  before adding them, see above.

+string-list API
+===============
+
+The string_list API offers a data structure and functions to handle sorted
+and unsorted string lists.
+
+The 'string_list' struct used to be called 'path_list', but was renamed
+because it is not specific to paths.
+
+The caller:
+
+. Allocates and clears a `struct string_list` variable.
+
+. Initializes the members. You might want to set the flag `strdup_strings`
+  if the strings should be strdup()ed. For example, this is necessary
+  when you add something like git_path("..."), since that function returns
+  a static buffer that will change with the next call to git_path().
++
+If you need something advanced, you can manually malloc() the `items`
+member (you need this if you add things later) and you should set the
+`nr` and `alloc` members in that case, too.
+
+. Adds new items to the list, using `string_list_append` or
+  `string_list_insert`.
+
+. Can check if a string is in the list using `string_list_has_string` or
+  `unsorted_string_list_has_string` and get it from the list using

Pierre Habouzit noticed that two variables were not static which should
have been, and that adding "\n\n" is better than adding '\n' twice.

Subject: Compact commit template message

We recently let the user know explicitly that an empty
commit message will abort the commit. However, this adds yet
another line to the template; let's rephrase and re-wrap so
that this fits back on two lines.

This patch also makes the "fatal: empty commit message?"
warning a bit less scary, since this is now a "feature"
instead of an error. However, we retain the non-zero exit
status to indicate to callers that nothing was committed.

Subject: Files given on the command line are relative to $cwd

When running "git commit -F file" and "git tag -F file" from a
subdirectory, we should take it as relative to the directory we started
from, not relative to the top-level directory.

This adds a helper function "parse_options_fix_filename()" to make it more
convenient to fix this class of issues.  Ideally, parse_options() should
support a new type of option, "OPT_FILENAME", to do this uniformly, but
this patch is meant to go to 'maint' to fix it minimally.

One thing to note is that value for "commit template file" that comes from
the command line is taken as relative to $cwd just like other parameters,
but when it comes from the configuration varilable 'commit.template', it
is taken as relative to the working tree root as before.  I think this
difference actually is sensible (not that I particularly think
commit.template itself is sensible).

Subject: pretty=format: respect date format options

When running a command like:

  git log --pretty=format:%ad --date=short

the date option was ignored. This patch causes it to use whatever
format was specified by --date (or by --relative-date, etc), just
as the non-user formats would do.

Subject: git commit --author=$name: look $name up in existing commits

This allows "git commit --author=$name" to accept a name that is not in
the required "A U Thor <author@example.xz>" format, and use that to look
up an author name that matches from existing commits.

When using this feature, it is the user's responsibility to give a name
that uniquely matches the name s/he wants, as the logic returns the name
from the first matching commit.

Subject: cast pid_t's to uintmax_t to improve portability

Some systems (like e.g. OpenSolaris) define pid_t as long,
therefore all our sprintf that use %i/%d cause a compiler warning
beacuse of the implicit long->int cast. To make sure that
we fit the limits, we display pids as PRIuMAX and cast them explicitly
to uintmax_t.

Subject: builtin-commit: use commit_tree()

First, it adds less code than removes, second this allows us to use
recuce_heads() for parents, so that the parents of a merge will be
always the same with or without a conflict.

Subject: Clarify commit error message for unmerged files

Currently, trying to use git-commit with unmerged files in the index
will show the message "Error building trees", which can be a bit
obscure to the end user. This patch makes the error message clearer, and
consistent with what git-write-tree reports in a similar situation.

Subject: git commit: Reformat output somewhat

Previously, we used to print something along the lines of

	Created commit abc9056 on master: Snib the sprock

but that output was sometimes confusing, as many projects use
the "subsystem: message" style of commit subjects (just like
this commit message does). When such improvements are done on
topic-branches, it's not uncommon to name the topic-branch the
same as the subsystem, leading to output like this:

	Created commit abc9056 on i386: i386: Snib the sprock

which doesn't look very nice and can be highly confusing.
This patch alters the format so that the noise-word "commit"
is dropped except when it makes the output read better and
the commit subject is put inside parentheses. We also
emphasize the detached case so that users do not overlook it
in case the commit subject is long enough to extend to the
next line. The end result looks thusly:

	normal case
	Created abc9056 (i386: Snib the sprock) on i386

	detached head
	Created DETACHED commit abc9056 (i386: Snib the sprock)

While we're at it, we rename "initial commit" to "root-commit"
to align it with the argument to 'git log', producing this:

	initial commit
	Created root-commit abc9056 (i386: Snib the sprock) on i386

Documentation/gittutorial-2.txt is updated accordingly so that
new users recognize what they're looking at.

Subject: reformat informational commit message

When committing, we print a message like:

  Created [DETACHED commit] <hash> (<subject>) on <branch>

The most useful bit of information there (besides the
detached status, if it is present) is which branch you made
the commit on. However,  it is sometimes hard to see because
the subject dominates the line.

Instead, let's put the most useful information (detached
status and commit branch) on the far left, with the subject
(which is least likely to be interesting) on the far right.

We'll use brackets to offset the branch name so the line is
not mistaken for an error line of the form "program: some
sort of error". E.g.,:

  [jk/bikeshed] created bd8098f: "reformat informational commit message"

Subject: builtin-commit: use reduce_heads() only when appropriate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since commit 6bb6b034 (builtin-commit: use commit_tree(), 2008-09-10),
builtin-commit performs a reduce_heads() unconditionally.  However,
it's not always needed, and in some cases even harmful.

reduce_heads() is not needed for the initial commit or for an
"ordinary" commit, because they don't have any or have only one
parent, respectively.

reduce_heads() must be avoided when 'git commit' is run after a 'git
merge --no-ff --no-commit', otherwise it will turn the
non-fast-forward merge into fast-forward.  For the same reason,
reduce_heads() must be avoided when amending such a merge commit.

To resolve this issue, 'git merge' will write info about whether
fast-forward is allowed or not to $GIT_DIR/MERGE_MODE.  Based on this
info, 'git commit' will only perform reduce_heads() when it's
committing a merge and fast-forward is enabled.

Also add test cases to ensure that non-fast-forward merges are
committed and amended properly.

From f285a2d7ed6548666989406de8f0e7233eb84368 Mon Sep 17 00:00:00 2001
From: Brandon Casey <casey@nrlssc.navy.mil>
Date: Thu, 9 Oct 2008 14:12:12 -0500
Subject: Replace calls to strbuf_init(&foo, 0) with STRBUF_INIT initializer

Many call sites use strbuf_init(&foo, 0) to initialize local
strbuf variable "foo" which has not been accessed since its
declaration. These can be replaced with a static initialization
using the STRBUF_INIT macro which is just as readable, saves a
function call, and takes up fewer lines.

From acd3b9eca82e38950f94e4708b528b7dae09a7c8 Mon Sep 17 00:00:00 2001
From: Junio C Hamano <gitster@pobox.com>
Date: Fri, 17 Oct 2008 15:44:39 -0700
Subject: Enhance hold_lock_file_for_{update,append}() API

This changes the "die_on_error" boolean parameter to a mere "flags", and
changes the existing callers of hold_lock_file_for_update/append()
functions to pass LOCK_DIE_ON_ERROR.

Signed-off-by: Junio C Hamano <gitster@pobox.com>

Date: Wed, 12 Nov 2008 03:25:52 -0500
Subject: commit: Fix stripping of patch in verbose mode.

When the "-v" option is given, we put diff of what is to be committed into
the commit template, and then strip it back out again after the user has
edited it.

We used to look for the diff by searching for the "diff --git a/"
header. With diff.mnemonicprefix set in the configuration, however, this
pattern does not match.  The pattern is loosened to cover this case.

Also, if the user puts their own diff in the message (e.g., as a sample
output), then we will accidentally trigger the pattern, removing part of
their output.

We can avoid doing this stripping altogether if the user didn't use "-v"
in the first place, so we know that any match we find will be a false
positive.

[jc: this fix was split out of a series originally meant for master.]

Date: Thu, 13 Nov 2008 16:36:30 -0800
Subject: Add cache preload facility

This can do the lstat() storm in parallel, giving potentially much
improved performance for cold-cache cases or things like NFS that have
weak metadata caching.

Just use "read_cache_preload()" instead of "read_cache()" to force an
optimistic preload of the index stat data.  The function takes a
pathspec as its argument, allowing us to preload only the relevant
portion of the index.

Subject: git add --intent-to-add: do not let an empty blob be committed by
 accident

Writing a tree out of an index with an "intent to add" entry is blocked.
This implies that you cannot "git commit" from such a state; however you
can still do "git commit -a" or "git commit $that_path".

When using "git commit" and there was nothing to commit (the editor

Subject: remove pathspec_match, use match_pathspec instead

Both versions have the same functionality. This removes any
redundancy.

This also adds makes two extensions to match_pathspec:

- If pathspec is NULL, return 1. This reflects the behavior of git
  commands, for which no paths usually means "match all paths".

- If seen is NULL, do not use it.

Subject: 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.

Subject: 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.

Subject: commit: more compact summary and without extra quotes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Update the report format again to save the screen real estates, while
avoiding from enclosing the one-line summary of the commit log inside
double quotes pair, which looks awkward when the message begins or ends
with a double quote.  The old format looked like this:

    [master]: created d9a5491: "foo:bar"

Simply removing the double quotes were found to be confusing as a message
often begins with a short-word (area of the system) and a colon.

The new format looks like this:

    [master d9a5491] foo:bar

As discussed in the git mailing list:

Subject: Generalize and libify index_is_dirty() to index_differs_from(...)

index_is_dirty() in builtin-revert.c checks if the index is dirty.
This patch generalizes this function to check if the index differs
from a revision, i.e. the former index_is_dirty() behavior can now be
achieved by index_differs_from("HEAD", 0).

The second argument "diff_flags" allows to set further diff option
flags like DIFF_OPT_IGNORE_SUBMODULES. See DIFF_OPT_* macros in diff.h
for a list.

index_differs_from() seems to be useful for more than builtin-revert.c,
so it is moved into diff-lib.c and also used in builtin-commit.c.

Yet to mention:

 - "rev.abbrev = 0;" can be safely removed.
   This has no impact on performance or functioning of neither
   setup_revisions() nor run_diff_index().

 - rev.pending.objects is free()d because this fixes a leak.
   (Also see 295dd2ad "Fix memory leak in traverse_commit_list")

Previously we ignored the result of calling add_interactive,
which meant that if an error occurred we simply committed
whatever happened to be in the index.
