cbce6c0be3 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.

6bb6b0341a 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.

85e7283069 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.

146ea068a0 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.

dbd0f5c769 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).

fdc7c81111 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.

67bfc030d7 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.

d5350fd2b3 commit --interactive: properly update the index before commiting
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

d177cab048 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.

4da45bef56 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.

34110cd4e3 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.

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.

959ba670ad 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.

8089c85bcb 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.

5a9dd3998f 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.

7a51ed66f6 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

4439751dcb 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.

We are calling overlay_tree_on_cache() which does use CE_UPDATE

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.

5f06573743 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).

37d07f8f98 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.

774751a8bc 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.

8babab95af builtin-commit.c: export GIT_INDEX_FILE for launch_editor as well.
The editor program to let the user edit the log message used to
get GIT_INDEX_FILE environment variable pointing at the right
file, but this was lost when git-commit was rewritten in C.

3f061887c5 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.

run_diff_index() and the entire diff machinery is hard coded to output
to stdout, so just redirect that and restore it when done.

2888605c64 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.
