b6f637d199 builtin-branch: fix -v for --[no-]merged
After the optimization to --[no-]merged logic, the calculation of the
width of the longest refname to be shown might become inaccurate (since
the matching against merge_filter is performed after adding refs to
ref_list). This patch forces a recalculation of maxwidth when it might
be needed.

68067ca1ef builtin-branch.c: optimize --merged and --no-merged
"git branch --no-merged $commit" used to compute the merge base between
the tip of each and every branch with the named $commit, but this was
wasteful when you have many branches.  Inside append_ref() we literally
ran has_commit() between the tip of the branch and the merge_filter_ref.

Instead, we can let the revision machinery traverse the history as if we
are running:

    $ git rev-list --branches --not $commit

by queueing the tips of branches we encounter as positive refs (this
mimicks the "--branches" option in the above command line) and then
appending the merge_filter_ref commit as a negative one, and finally
calling prepare_revision_walk() to limit the list..

After the traversal is done, branch tips that are reachable from $commit
are painted UNINTERESTING; they are already fully contained in $commit
(i.e. --merged).  Tips that are not painted UNINTERESTING still have
commits that are not reachable from $commit, thus "--no-merged" will show
them.

With an artificial repository that has "master" and 1000 test-$i branches
where they were created by "git branch test-$i master~$i":

1b1dd23f2d 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.

049716b370 branch --merged/--no-merged: allow specifying arbitrary commit
"git-branch --merged" is a handy way to list all the branches that have
already been merged to the current branch, but it did not allow checking
against anything but the current branch.  Having to switch branches only
to list the branches that are merged with another branch made the feature
practically useless.

This updates the option parser so that "git branch --merged next" is
accepted when you are on 'master' branch.

e8b404c27e git-branch: add support for --merged and --no-merged
These options filter the output from git branch to only include branches
whose tip is either merged or not merged into HEAD.

The use-case for these options is when working with integration of branches
from many remotes: `git branch --no-merged -a` will show a nice list of merge
candidates while `git branch --merged -a` will show the progress of your
integration work.

Also, a plain `git branch --merged` is a quick way to find local branches
which you might want to delete.

8e0f70033b Avoid unnecessary "if-before-free" tests.
This change removes all obvious useless if-before-free tests.
E.g., it replaces code like this:

        if (some_expression)
                free (some_expression);

with the now-equivalent:

        free (some_expression);

It is equivalent not just because POSIX has required free(NULL)
to work for a long time, but simply because it has worked for
so long that no reasonable porting target fails the test.
Here's some evidence from nearly 1.5 years ago:

    http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html

FYI, the change below was prepared by running the following:

  git ls-files -z | xargs -0 \
  perl -0x3b -pi -e \
    's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s'

Note however, that it doesn't handle brace-enclosed blocks like
"if (x) { free (x); }".  But that's ok, since there were none like
that in git sources.

Beware: if you do use the above snippet, note that it can
produce syntactically invalid C code.  That happens when the
affected "if"-statement has a matching "else".
E.g., it would transform this

  if (x)
    free (x);
  else
    foo ();

into this:

  free (x);
  else
    foo ();

There were none of those here, either.

If you're interested in automating detection of the useless
tests, you might like the useless-if-before-free script in gnulib:
[it *does* detect brace-enclosed free statements, and has a --name=S
 option to make it detect free-like functions with different names]

  http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free

Addendum:
  Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

9ed36cfa35 branch: optionally setup branch.*.merge from upstream local branches
"git branch" and "git checkout -b" now honor --track option even when
the upstream branch is local.  Previously --track was silently ignored
when forking from a local branch.  Also the command did not error out
when --track was explicitly asked for but the forked point specified
was not an existing branch (i.e. when there is no way to set up the
tracking configuration), but now it correctly does.

The configuration setting branch.autosetupmerge can now be set to
"always", which is equivalent to using --track from the command line.
Setting branch.autosetupmerge to "true" will retain the former behavior
of only setting up branch.*.merge for remote upstream branches.

Includes test cases for the new functionality.

0f6f5a4022 git config --get-colorbool
This adds an option to help scripts find out color settings from
the configuration file.

    git config --get-colorbool color.diff

inspects color.diff variable, and exits with status 0 (i.e. success) if
color is to be used.  It exits with status 1 otherwise.

If a script wants "true"/"false" answer to the standard output of the
command, it can pass an additional boolean parameter to its command
line, telling if its standard output is a terminal, like this:

    git config --get-colorbool color.diff true

When called like this, the command outputs "true" to its standard output
if color is to be used (i.e. "color.diff" says "always", "auto", or
"true"), and "false" otherwise.

694a577519 git-branch --contains=commit
This teaches git-branch to limit its listing to branches that
are descendants to the named commit.

When you are using many topic branches, you often would want to
see which branch already includes a commit, so that you know
which can and cannot be rewound without disrupting other people.

One thing that sometimes happens to me is:

 * Somebody sends a patch that is a good maint material.  I
   apply it to 'maint':

     $ git checkout maint
     $ git am -3 -s obvious-fix.patch

 * Then somebody else sends another patch that is possibly a
   good maint material, but I'd want to cook it in 'next' to be
   extra sure.  I fork a topic from 'maint' and apply the patch:

     $ git checkout -b xx/maint-fix-foo
     $ git am -3 -s ,xx-maint-fix-foo.patch

 * A minor typo is found in the "obvious-fix.patch".

The above happens without pushing the results out, so I can
freely recover from it by amending 'maint', as long as I do not
forget to rebase the topics that were forked previously.

With this patch, I can do this to find out which topic
branches already contain the faulty commit:

    $ git branch --contains=maint^
      xx/maint-fix-foo

so I can rebase the xx/maint-fix-foo branch before merging it
to 'next'.

6f084a56fc branch --track: code cleanup and saner handling of local branches
This patch cleans up some complicated code, and replaces it with a
cleaner version, using code from remote.[ch], which got extended a
little in the process.  This also enables us to fix two cases:

The earlier "fix" to setup tracking only when the original ref started
with "refs/remotes" is wrong.  You are absolutely allowed to use a
separate layout for your tracking branches.  The correct fix, of course,
is to set up tracking information only when there is a matching
remote.<nick>.fetch line containing a colon.

Another corner case was not handled properly.  If two remotes write to
the original ref, just warn the user and do not set up tracking.

4017761fd8 branch.autosetupmerge: allow boolean values, or "all"
Junio noticed that switching on autosetupmerge unilaterally started
cluttering the config for local branches.  That is not the original
intention of branch.autosetupmerge, which was meant purely for
convenience when branching off of remote branches, but that semantics
got lost somewhere.

If you still want that "new" behavior, you can switch
branch.autosetupmerge to the value "all".  Otherwise, it is interpreted
as a boolean, which triggers setting up defaults _only_ when branching
off of a remote branch, i.e. the originally intended behavior.

80583c0ef6 Lift 16kB limit of log message output
Traditionally we had 16kB limit when formatting log messages for
output, because it was easier to arrange for the caller to have
a reasonably big buffer and pass it down without ever worrying
about reallocating.

This changes the calling convention of pretty_print_commit() to
lift this limit.  Instead of the buffer and remaining length, it
now takes a pointer to the pointer that points at the allocated
buffer, and another pointer to the location that stores the
allocated length, and reallocates the buffer as necessary.

To support the user format, the error return of interpolate()
needed to be changed.  It used to return a bool telling "Ok the
result fits", or "Sorry, I had to truncate it".  Now it returns
0 on success, and returns the size of the buffer it wants in
order to fit the whole result.

19eba1515a Make builtin-branch.c handle the git config file
This moves the knowledge about .git/config usage out of refs.c and into
builtin-branch.c instead, which allows git-branch to update HEAD to point
at the moved branch before attempting to update the config file. It also
allows git-branch to exit with an error code if updating the config file
should fail.

9debc3241b git-fetch, git-branch: Support local --track via a special remote '.'
This patch adds support for a dummy remote '.' to avoid having
to declare a fake remote like

        [remote "local"]
                url = .
                fetch = refs/heads/*:refs/heads/*

Such a builtin remote simplifies the operation of "git-fetch",
which will populate FETCH_HEAD but will not pretend that two
repositories are in use, will not create a thin pack, and will
not perform any useless remapping of names.  The speed
improvement is around 20%, and it should improve more if
"git-fetch" is converted to a builtin.

To this end, git-parse-remote is grown with a new kind of
remote, 'builtin'.  In git-fetch.sh, we treat the builtin remote
specially in that it needs no pack/store operations.  In fact,
doing git-fetch on a builtin remote will simply populate
FETCH_HEAD appropriately.

The patch also improves of the --track/--no-track support,
extending it so that branch.<name>.remote items referring '.'
can be created.  Finally, it fixes a typo in git-checkout.sh.

0746d19a82 git-branch, git-checkout: autosetup for remote branch tracking
In order to track and build on top of a branch 'topic' you track from
your upstream repository, you often would end up doing this sequence:

  git checkout -b mytopic origin/topic
  git config --add branch.mytopic.remote origin
  git config --add branch.mytopic.merge refs/heads/topic

This would first fork your own 'mytopic' branch from the 'topic'
branch you track from the 'origin' repository; then it would set up two
configuration variables so that 'git pull' without parameters does the
right thing while you are on your own 'mytopic' branch.

This commit adds a --track option to git-branch, so that "git
branch --track mytopic origin/topic" performs the latter two actions
when creating your 'mytopic' branch.

If the configuration variable branch.autosetupmerge is set to true, you
do not have to pass the --track option explicitly; further patches in
this series allow setting the variable with a "git remote add" option.
The configuration variable is off by default, and there is a --no-track
option to countermand it even if the variable is set.

3a55602eec General const correctness fixes
We shouldn't attempt to assign constant strings into char*, as the
string is not writable at runtime.  Likewise we should always be
treating unsigned values as unsigned values, not as signed values.

Most of these are very straightforward.  The only exception is the
(unnecessary) xstrdup/free in builtin-branch.c for the detached
head case.  Since this is a user-level interactive type program
and that particular code path is executed no more than once, I feel
that the extra xstrdup call is well worth the easy elimination of
this warning.

cc44c7655f Mechanical conversion to use prefixcmp()
This mechanically converts strncmp() to use prefixcmp(), but only when
the parameters match specific patterns, so that they can be verified
easily.  Leftover from this will be fixed in a separate step, including
idiotic conversions like

    if (!strncmp("foo", arg, 3))

  =>

    if (!(-prefixcmp(arg, "foo")))

This was done by using this script in px.perl

   #!/usr/bin/perl -i.bak -p
   if (/strncmp\(([^,]+), "([^\\"]*)", (\d+)\)/ && (length($2) == $3)) {
           s|strncmp\(([^,]+), "([^\\"]*)", (\d+)\)|prefixcmp($1, "$2")|;
   }
   if (/strncmp\("([^\\"]*)", ([^,]+), (\d+)\)/ && (length($1) == $3)) {
           s|strncmp\("([^\\"]*)", ([^,]+), (\d+)\)|(-prefixcmp($2, "$1"))|;
   }

and running:

   $ git grep -l strncmp -- '*.c' | xargs perl px.perl
