Move "commit->buffer" out of the in-core commit object and keep
track of their lengths. Use this to optimize the code paths to
validate GPG signatures in commit objects.
* jk/commit-buffer-length:
reuse cached commit buffer when parsing signatures
commit: record buffer length in cache
commit: convert commit->buffer to a slab
commit-slab: provide a static initializer
use get_commit_buffer everywhere
convert logmsg_reencode to get_commit_buffer
use get_commit_buffer to avoid duplicate code
use get_cached_commit_buffer where appropriate
provide helpers to access the commit buffer
provide a helper to set the commit buffer
provide a helper to free commit buffer
sequencer: use logmsg_reencode in get_message
logmsg_reencode: return const buffer
do not create "struct commit" with xcalloc
commit: push commit_index update into alloc_commit_node
alloc: include any-object allocations in alloc_report
replace dangerous uses of strbuf_attach
commit_tree: take a pointer/len pair rather than a const strbuf

Most callsites which use the commit buffer try to use the
cached version attached to the commit, rather than
re-reading from disk. Unfortunately, that interface provides
only a pointer to the NUL-terminated buffer, with no
indication of the original length.
For the most part, this doesn't matter. People do not put
NULs in their commit messages, and the log code is happy to
treat it all as a NUL-terminated string. However, some code
paths do care. For example, when checking signatures, we
want to be very careful that we verify all the bytes to
avoid malicious trickery.
This patch just adds an optional "size" out-pointer to
get_commit_buffer and friends. The existing callers all pass
NULL (there did not seem to be any obvious sites where we
could avoid an immediate strlen() call, though perhaps with
some further refactoring we could).

Each of these sites assumes that commit->buffer is valid.
Since they would segfault if this was not the case, they are
likely to be correct in practice. However, we can
future-proof them by using get_commit_buffer.
And as a side effect, we abstract away the final bare uses
of commit->buffer.

Like the callsites in the previous commit, logmsg_reencode
already falls back to read_sha1_file when necessary.
However, I split its conversion out into its own commit
because it's a bit more complex.
We return either:
1. The original commit->buffer
2. A newly allocated buffer from read_sha1_file
3. A reencoded buffer (based on either 1 or 2 above).
while trying to do as few extra reads/allocations as
possible. Callers currently free the result with
logmsg_free, but we can simplify this by pointing them
straight to unuse_commit_buffer. This is a slight layering
violation, in that we may be passing a buffer from (3).
However, since the end result is to free() anything except
(1), which is unlikely to change, and because this makes the
interface much simpler, it's a reasonable bending of the
rules.

This simplifies the code, as logmsg_reencode handles the
reencoding for us in a single call. It also means we learn
logmsg_reencode's trick of pulling the buffer from disk when
commit->buffer is NULL (we currently just silently return!).
It is doubtful this matters in practice, though, as
sequencer operations would not generally turn off
save_commit_buffer.
Note that we may be fixing a bug here. The existing code
does:
if (same_encoding(to, from))
reencode_string(buf, to, from);
That probably should have been "!same_encoding".

`do_pick_commit` handles three situations if it is not fast-forwarding.
In order for `do_pick_commit` to identify the situation, it examines the
return value of the selected merge command.
1. return value 0 stands for a clean merge
2. 1 is passed in case of a failed merge due to conflict
3. any other return value means that the merge did not even start
So far, the sequencer returns 1 in case of a failed fast-forward, which
would mean "failed merge due to conflict". However, a fast-forward
either starts and succeeds or does not start at all. In particular, it
cannot fail in between like a merge with a dirty index due to conflicts.
In order to signal the three possible situations (not only success and
failure to complete) after a pick through porcelain commands such as
`cherry-pick`, exit with a return value that is neither 0 nor 1. 128 was
chosen in line with the other situations in which the sequencer
encounters an error. In such situations, the sequencer returns a
negative value and `cherry-pick` translates this into a call to `die`.
`die` then terminates the process with exit status 128.

Change fast_forward_to() to check if locking the ref failed, print a
nice error message and bail out early.
The old code did not check if ref_lock was NULL and relied on the
fact that the write_ref_sha1() would safely detect this condition
and set the return variable ret to indicate an error.
While that is safe, it makes the code harder to read for two reasons:
* Inconsistency. Almost all other places we do check the lock for
NULL explicitly, so the naive reader is confused "why don't we
check here?"
* And relying on write_ref_sha1() to detect and return an error for
when a previous lock_any_ref_for_update() failed feels obfuscated.
This change should not change any functionality or logic aside from
adding an extra error message when this condition is triggered
(write_ref_sha1() returns an error silently for this condition).

new topic in flight can still make use of the old functions, replace
existing uses of the prefixcmp() and suffixcmp() with new API
functions.
The change can be recreated by mechanically applying this:

I attempted to make index_state->cache[] a "const struct cache_entry **"
to find out how existing entries in index are modified and where. The
question I have is what do we do if we really need to keep track of on-disk
changes in the index. The result is
- diff-lib.c: setting CE_UPTODATE
- name-hash.c: setting CE_HASHED
- preload-index.c, read-cache.c, unpack-trees.c and
builtin/update-index: obvious
- entry.c: write_entry() may refresh the checked out entry via
fill_stat_cache_info(). This causes "non-const struct cache_entry
*" in builtin/apply.c, builtin/checkout-index.c and
builtin/checkout.c
- builtin/ls-files.c: --with-tree changes stagemask and may set
CE_UPDATE
Of these, write_entry() and its call sites are probably most
interesting because it modifies on-disk info. But this is stat info
and can be retrieved via refresh, at least for porcelain
commands. Other just uses ce_flags for local purposes.
So, keeping track of "dirty" entries is just a matter of setting a
flag in index modification functions exposed by read-cache.c. Except
unpack-trees, the rest of the code base does not do anything funny
behind read-cache's back.
The actual patch is less valueable than the summary above. But if
anyone wants to re-identify the above sites. Applying this patch, then
this:
diff --git a/cache.h b/cache.h
index 430d021..1692891 100644

'commit -s' populates the edit buffer with a blank line before the
Signed-off-by line, to allow the user to immediately start typing
the log message. But commit 33f2f9ab removed this space, forcing
the user to first push the Signed-off-by line down to open a place
to type the log message.
Fix this regression and let's ensure that the Signed-off-by line is
preceded by two blank lines, instead of just one, to hint that
something should be filled in, and that a blank line should separate
it from the body and the Signed-off-by line.
Add a test for this behavior.

Currently, append_signoff() performs a search for the last line of the
commit buffer by searching back from the end until it hits a newline. If
it reaches the beginning of the buffer without finding a newline, that
means either the commit message was empty, or there was only one line in it.
In this case, append_signoff will skip the call to has_conforming_footer
since it already knows that it is necessary to append a newline before
appending the sob.
Let's perform this function inside of has_conforming_footer where it
appropriately belongs and generalize it so that we require that the
footer paragraph be an actual distinct paragraph separated by a blank
line.

It even included support for accepting indented continuation lines for
multiline fields. Unfortunately the multiline field support is broken
because it checks whether buf[k] (the first character of the *next* line)
instead of buf[i] is a whitespace character. The result is that any footer
with a continuation line is not accepted, since the last continuation line
neither starts with an RFC2822 field name nor is followed by a continuation
line.
That this has remained broken for so long is good evidence that nobody
actually needed multiline fields. Rip out the broken continuation support.
There should be no functional change.

Various codepaths checked if two encoding names are the same using
ad-hoc code and some of them ended up asking iconv() to convert
between "utf8" and "UTF-8". The former is not a valid way to spell
the encoding name, but often people use it by mistake, and we
equated them in some but not all codepaths. Introduce a new helper
function to make these codepaths consistent.

Callers of reencode_string() that re-encodes a string from one
encoding to another all used ad-hoc way to bypass the case where the
input and the output encodings are the same. Some did strcmp(),
some did strcasecmp(), yet some others when converting to UTF-8 used
is_encoding_utf8().
Introduce same_encoding() helper function to make these callers use
the same logic. Notably, is_encoding_utf8() has a work-around for
common misconfiguration to use "utf8" to name UTF-8 encoding, which
does not match "UTF-8" hence strcasecmp() would not consider the
same. Make use of it in this helper function.

These functions are called in sequencer.c, which is part of
libgit.a. This makes libgit.a potentially require builtin/merge.c for
external git commands.

In case 'git cherry-pick -s <commit>' failed, the user had to use 'git
commit -s' (i.e. state the -s option again), which is easy to forget
about. Instead, write the signed-off-by line early, so plain 'git
commit' will have the same result.
Also update 'git commit -s', so that in case there is already a relevant
Signed-off-by line before the Conflicts: line, it won't add one more at
the end of the message. If there is no such line, then add it before the
the Conflicts: line.

"git cherry-pick A C B" used to replay changes in A and then B and
then C if these three commits had committer timestamps in that
order, which is not what the user who said "A C B" naturally expects.

When giving multiple individual revisions to cherry-pick or revert, as
in 'git cherry-pick A B' or 'git revert B A', one would expect them to
be picked/reverted in the order given on the command line. They are
instead ordered by their commit timestamp -- in chronological order
for "cherry-pick" and in reverse chronological order for
"revert". This matches the order in which one would usually give them
on the command line, making this bug somewhat hard to notice. Still,
it has been reported at least once before [1].
It seems like the chronological sorting happened by accident because
the revision walker has traditionally always sorted commits in reverse
chronological order when rev_info.no_walk was enabled. In the case of
'git revert B A' where B is newer than A, this sorting is a no-op. For
'git cherry-pick A B', the sorting would reverse the arguments, but
because the sequencer also flips the rev_info.reverse flag when
picking (as opposed to reverting), the end result is a chronological
order. The rev_info.reverse flag was probably flipped so that the
revision walker emits B before C in 'git cherry-pick A..C'; that it
happened to effectively undo the unexpected sorting done when not
walking, was probably a coincidence that allowed this bug to happen at
all.
Fix the bug by telling the revision walker not to sort the commits
when not walking. The only case we want to reverse the order is now
when cherry-picking and walking revisions (rev_info.no_walk = 0).

Scripts such as "git rebase -i" cannot currently cherry-pick commits
which have an empty commit message, as git cherry-pick calls git
commit without the --allow-empty-message option.
Add an --allow-empty-message option to git cherry-pick which is passed
through to git commit, so this behaviour can be overridden.

The earlier "--keep-redundant-commit" series broke "cherry-pick"
that is given a commit whose change is already in the current
history. Such a cherry-pick would result in an empty change, and
should stop with an error, telling the user that conflict resolution
may have made the result empty (which is exactly what is happening),
but we silently dropped the change on the floor without any message
nor non-zero exit code.

In the case the pointer could be NULL, the function that gave the caller
the NULL pointer would already have issued an error message, so simply
returning early with an error status without issuing a new message is
sufficient. The same for parse_commit() that will show necessary error
message when the argument is not NULL, and will return error silently
when the argument is NULL.

any change in the original history.

The git-cherry-pick --allow-empty command by default only preserves empty
commits that were originally empty, i.e only those commits for which
<commit>^{tree} and <commit>^^{tree} are equal. By default commits which are
non-empty, but were made empty by the inclusion of a prior commit on the current
history are filtered out. This option allows us to override that behavior and
include redundant commits as empty commits in the change history.
Note that this patch changes the default behavior of git cherry-pick slightly.
Prior to this patch all commits in a cherry-pick sequence were applied and git
commit was run. The implication here was that, if a commit was redundant, and
the commit did not trigger the fast forward logic, the git commit operation, and
therefore the git cherry-pick operation would fail, displaying the cherry pick
advice (i.e. run git commit --allow-empty). With this patch however, such
redundant commits are automatically skipped without stopping, unless
--keep-redundant-commits is specified, in which case, they are automatically
applied as empty commits.

git cherry-pick fails when picking a non-ff commit that is empty. The advice
given with the failure is that a git-commit --allow-empty should be issued to
explicitly add the empty commit during the cherry pick. This option allows a
user to specify before hand that they want to keep the empty commit. This
eliminates the need to issue both a cherry pick and a commit operation.
