Junio C Hamano 1154aa4215 fmt-merge-msg: plug small leak of commit buffer
A broken or badly formatted commit might not record author or
committer lines or we may not find a valid name on them.  The
function record_person() returned after calling get_commit_buffer()
without calling unuse_commit_buffer() on the memory it obtained in
such cases, potentially leaking it.

Alex Henrie 9c9b4f2f8b standardize usage info string format
This patch puts the usage info strings that were not already in docopt-
like format into docopt-like format, which will be a litle easier for
end users and a lot easier for translators. Changes include:

- Placing angle brackets around fill-in-the-blank parameters
- Putting dashes in multiword parameter names
- Adding spaces to [-f|--foobar] to make [-f | --foobar]
- Replacing <foobar>* with [<foobar>...]

Ronnie Sahlberg 7695d118e5 refs.c: change resolve_ref_unsafe reading argument to be a flags field
resolve_ref_unsafe takes a boolean argument for reading (a nonexistent ref
resolves successfully for writing but not for reading).  Change this to be
a flags field instead, and pass the new constant RESOLVE_REF_READING when
we want this behaviour.

While at it, swap two of the arguments in the function to put output
arguments at the end.  As a nice side effect, this ensures that we can
catch callers that were unaware of the new API so they can be audited.

Give the wrapper functions resolve_refdup and read_ref_full the same
treatment for consistency.

Jeff King 95b567c7c3 use skip_prefix to avoid repeating strings
It's a common idiom to match a prefix and then skip past it
with strlen, like:

  if (starts_with(foo, "bar"))
	  foo += strlen("bar");

This avoids magic numbers, but means we have to repeat the
string (and there is no compiler check that we didn't make a
typo in one of the strings).

We can use skip_prefix to handle this case without repeating
ourselves.

Jeff King cf4fff579e refactor skip_prefix to return a boolean
The skip_prefix() function returns a pointer to the content
past the prefix, or NULL if the prefix was not found. While
this is nice and simple, in practice it makes it hard to use
for two reasons:

  1. When you want to conditionally skip or keep the string
     as-is, you have to introduce a temporary variable.
     For example:

       tmp = skip_prefix(buf, "foo");
       if (tmp)
	       buf = tmp;

  2. It is verbose to check the outcome in a conditional, as
     you need extra parentheses to silence compiler
     warnings. For example:

       if ((cp = skip_prefix(buf, "foo"))
	       /* do something with cp */

Both of these make it harder to use for long if-chains, and
we tend to use starts_with() instead. However, the first line
of "do something" is often to then skip forward in buf past
the prefix, either using a magic constant or with an extra
strlen(3) (which is generally computed at compile time, but
means we are repeating ourselves).

This patch refactors skip_prefix() to return a simple boolean,
and to provide the pointer value as an out-parameter. If the
prefix is not found, the out-parameter is untouched. This
lets you write:

  if (skip_prefix(arg, "foo ", &arg))
	  do_foo(arg);
  else if (skip_prefix(arg, "bar ", &arg))
	  do_bar(arg);

Jeff King c0264180d7 avoid using skip_prefix as a boolean
There's no point in using:

  if (skip_prefix(buf, "foo"))

over

  if (starts_with(buf, "foo"))

as the point of skip_prefix is to return a pointer to the
data after the prefix. Using starts_with is more readable,
and will make refactoring skip_prefix easier.

Jeff King 8597ea3afe commit: record buffer length in cache
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).

Jeff King bc6b8fc130 use get_commit_buffer everywhere
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.

Leaving only the function definitions and declarations so that any
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:

      grep -v strbuf\\.c |
      xargs perl -pi -e '

Some users do want to write a line that begin with a pound sign, #,
in their commit log message.  Many tracking system recognise
a token of #<bugid> form, for example.

The support we offer these use cases is not very friendly to the end
users.  They have a choice between

 - Don't do it.  Avoid such a line by rewrapping or indenting; and

 - Use --cleanup=whitespace but remove all the hint lines we add.

Give them a way to set a custom comment char, e.g.

    $ git -c core.commentchar="%" commit

so that they do not have to do either of the two workarounds.

The credit lines "By" and "Via" to credit authors and committers for
their contributions on the side branch are meant as a hint to the
integrator to decide whom to mention in the log message text.  After
the integrator saves the message in the editor, they are meant to go
away and that is why they are commented out.

When a merge is recorded without editing the generated message,
however, its contents do not go through the normal stripspace()
and these lines are left in the merge.

Stop producing them when we know the merge is going to be recorded
without editing, i.e. when --no-edit is given.

Linus Torvalds a3347b988a fmt-merge-message: add empty line between tag and signature verification
When adding the information from a tag, put an empty line between the
message of the tag and the commented-out signature verification
information.

At least for the kernel workflow, I often end up re-formatting the message
that people send me in the tag data. In that situation, putting the tag
message and the tag signature verification back-to-back then means that
normal editor "reflow parapgraph" command will get confused and think that
the signature is a continuation of the last message paragraph.

So I always end up having to first add an empty line, and then go back and
reflow the last paragraph. Let's just do it in git directly.

The extra vertical space also makes the verification visually stand out
more from the user-supplied message, so it looks a bit more readable to me
too, but that may be just an odd personal preference.

The record_person function just parses out the "name" field
of the person line in a commit and adds it to a string_list.
The only reason we need an extra buffer is that the
string_list functions require a NUL-terminated string.

Instead of the static buffer, we can just allocate a
temporary NUL-terminated copy. In addition to removing a
useless limit, this removes the only user of MAX_GITNAME
outside of ident.c.

Junio C Hamano 418a1435f1 fmt-merge-msg: show those involved in a merged series
As we already walk the history of the branch that gets merged to
come up with a short log, let's label it with names of the primary
authors, so that the user who summarizes the merge can easily give
credit to them in the log message.

Also infer the names of "lieutents" to help integrators at higher
level of the food-chain to give credit to them, by counting:

 * The committer of the 'tip' commit that is merged
 * The committer of merge commits that are merged

Often the first one gives the owner of the history being pulled, but
his last pull from his sublieutenants may have been a fast-forward,
in which case the first one would not be.  The latter rule will
count the integrator of the history, so together it might be a
reasonable heuristics.

There are two special cases:

 - The "author" credit is omitted when the series is written solely
   by the same author who is making the merge. The name can be seen
   on the "Author" line of the "git log" output to view the log
   message anyway.

 - The "lieutenant" credit is omitted when there is only one key
   committer in the merged branch and it is the committer who is
   making the merge. Typically this applies to the case where the
   developer merges his own branch.

Junio C Hamano 895680f044 fmt-merge-msg: Add contents of merged tag in the merge message
When a contributor asks the integrator to merge her history, a signed tag
can be a good vehicle to communicate the authenticity of the request while
conveying other information such as the purpose of the topic.

E.g. a signed tag "for-linus" can be created, and the integrator can run:

   $ git pull git://example.com/work.git/ for-linus

This would allow the integrator to run "git verify-tag FETCH_HEAD" to
validate the signed tag.

Update fmt-merge-msg so that it pre-fills the merge message template with
the body (but not signature) of the tag object to help the integrator write
a better merge message, in the same spirit as the existing merge.log summary
lines.

The message that comes from GPG signature validation is also included in
the merge message template to help the integrator verify it, but they are
prefixed with "#" to make them comments.

Junio C Hamano 898eacd8ad fmt-merge-msg: use branch.$name.description
This teaches "merge --log" and fmt-merge-msg to use branch description
information when merging a local topic branch into the mainline. The
description goes between the branch name label and the list of commit
titles.

The refactoring to share the common configuration parsing between
merge and fmt-merge-msg needs to be made into a separate patch.

Nguyễn Thái Ngọc Duy baf18fc261 Accept tags in HEAD or MERGE_HEAD
HEAD and MERGE_HEAD (among other branch tips) should never hold a
tag. That can only be caused by broken tools and is cumbersome to fix
by an end user with:

  $ git update-ref HEAD $(git rev-parse HEAD^{commit})

which may look like a magic to a new person.

Be easy, warn users (so broken tools can be fixed if they bother to
report) and move on.

Be robust, if the given SHA-1 cannot be resolved to a commit object,
die (therefore return value is always valid).

Matthieu Moy 13931236b9 Change incorrect "remote branch" to "remote tracking branch" in C code
(Just like we did for documentation already)

In the process, we change "non-remote branch" to "branch outside the
refs/remotes/ hierarchy" to avoid the ugly "non-remote-tracking branch".
The new formulation actually corresponds to how the code detects this
case (i.e. prefixcmp(refname, "refs/remotes")).

Also, we use 'remote-tracking branch' in generated merge messages (by
merge an fmt-merge-msg).

Give "shortlog_len" parameter to the fmt_merge_msg(), remove its
"merge_summary" parameter, and remove fmt_merge_msg_shortlog() function.
In the updated API, shortlog_len == 0 means no shortlog is given.

The parameter "merge_title" controls if the title of the merge commit is
autogenerated (it reads something like "Merge branch ..."), and typically
it is set to true when the caller does not give its own message.

Linus Torvalds 81b50f3ce4 Move 'builtin-*' into a 'builtin/' subdirectory
This shrinks the top-level directory a bit, and makes it much more
pleasant to use auto-completion on the thing. Instead of

	[torvalds@nehalem git]$ em buil<tab>
	Display all 180 possibilities? (y or n)
	[torvalds@nehalem git]$ em builtin-sh
	builtin-shortlog.c     builtin-show-branch.c  builtin-show-ref.c
	builtin-shortlog.o     builtin-show-branch.o  builtin-show-ref.o
	[torvalds@nehalem git]$ em builtin-shor<tab>
	builtin-shortlog.c  builtin-shortlog.o
	[torvalds@nehalem git]$ em builtin-shortlog.c

you get

	[torvalds@nehalem git]$ em buil<tab>		[type]
	builtin/   builtin.h
	[torvalds@nehalem git]$ em builtin		[auto-completes to]
	[torvalds@nehalem git]$ em builtin/sh<tab>	[type]
	shortlog.c     shortlog.o     show-branch.c  show-branch.o  show-ref.c     show-ref.o
	[torvalds@nehalem git]$ em builtin/sho		[auto-completes to]
	[torvalds@nehalem git]$ em builtin/shor<tab>	[type]
	shortlog.c  shortlog.o
	[torvalds@nehalem git]$ em builtin/shortlog.c

which doesn't seem all that different, but not having that annoying
break in "Display all 180 possibilities?" is quite a relief.

NOTE! If you do this in a clean tree (no object files etc), or using an
editor that has auto-completion rules that ignores '*.o' files, you
won't see that annoying 'Display all 180 possibilities?' message - it
will just show the choices instead.  I think bash has some cut-off
around 100 choices or something.

So the reason I see this is that I'm using an odd editory, and thus
don't have the rules to cut down on auto-completion.  But you can
simulate that by using 'ls' instead, or something similar.
