90e41a89ca receive-pack: remove unnecessary run_status report
The function run_status was used to report failures after a hook was run.
By now, the only thing that the function itself reported was the exit code
of the hook (if it was non-zero). But this is redundant because it can be
expected that the hook itself will have reported a suitable error.

c024beb56d run_command: report failure to execute the program, but optionally don't
In the case where a program was not found, it was still the task of the
caller to report an error to the user. Usually, this is an interesting case
but only few callers actually reported a specific error (though many call
sites report a generic error message regardless of the cause).

With this change the error is reported by run_command, but since there is
one call site in git.c that does not want that, an option is added to
struct child_process, which is used to turn the error off.

b99d5f40d6 run_command: encode deadly signal number in the return value
We now write the signal number in the error message if the program
terminated by a signal. The negative return value is constructed such that
after truncation to 8 bits it looks like a POSIX shell's $?:

   $ echo 0000 | { git upload-pack .; echo $? >&2; } | :
   error: git-upload-pack died of signal 13
   141

Previously, the exit code was 255 instead of 141.

0ac77ec315 run_command: report system call errors instead of returning error codes
The motivation for this change is that system call failures are serious
errors that should be reported to the user, but only few callers took the
burden to decode the error codes that the functions returned into error
messages.

If at all, then only an unspecific error message was given. A prominent
example is this:

   $ git upload-pack . | :
   fatal: unable to run 'git-upload-pack'

In this example, git-upload-pack, the external command invoked through the
git wrapper, dies due to SIGPIPE, but the git wrapper does not bother to
report the real cause. In fact, this very error message is copied to the
syslog if git-daemon's client aborts the connection early.

With this change, system call failures are reported immediately after the
failure and only a generic failure code is returned to the caller. In the
above example the error is now to the point:

   $ git upload-pack . | :
   error: git-upload-pack died of signal

Note that there is no error report if the invoked program terminated with
a non-zero exit code, because it is reasonable to expect that the invoked
program has already reported an error. (But many run_command call sites
nevertheless write a generic error message.)

There was one special return code that was used to identify the case where
run_command failed because the requested program could not be exec'd. This
special case is now treated like a system call failure with errno set to
ENOENT. No error is reported in this case, because the call site in git.c
expects this as a normal result. Therefore, the callers that carefully
decoded the return value still check for this condition.

5709e0363a run_command: return exit code as positive value
As a general guideline, functions in git's code return zero to indicate
success and negative values to indicate failure. The run_command family of
functions followed this guideline. But there are actually two different
kinds of failure:

- failures of system calls;

- non-zero exit code of the program that was run.

Usually, a non-zero exit code of the program is a failure and means a
failure to the caller. Except that sometimes it does not. For example, the
exit code of merge programs (e.g. external merge drivers) conveys
information about how the merge failed, and not all exit calls are
actually failures.

Furthermore, the return value of run_command is sometimes used as exit
code by the caller.

This change arranges that the exit code of the program is returned as a
positive value, which can now be regarded as the "result" of the function.
System call failures continue to be reported as negative values.

47e3de0e79 MinGW: truncate exit()'s argument to lowest 8 bits
For some reason, MinGW's bash cannot reliably detect failure of the child
process if a negative value is passed to exit(). This fixes it by
truncating the exit code in all calls of exit().

This issue was worked around in run_builtin() of git.c (2488df84 builtin
run_command: do not exit with -1, 2007-11-15). This workaround is no longer
necessary and is reverted.

6167c13657 git.c: avoid allocating one-too-many elements for new argv array
When creating a new argv array from a configured alias and the supplied
command line arguments, the new argv was allocated with one element too
many.  Since the first element of the original argv array is skipped when
copying it to the new_argv, the number of elements that are allocated
should be reduced by one.  'count' is the number of elements that new_argv
contains, and *argcp is the number of elements in the original argv array.
So the total allocation (including the terminating NULL entry) for the
new_argv array should be:

  count + (*argcp - 1) + 1

Also, the explicit assignment of the NULL terminating entry can be avoided
by just copying it over from the original argv array.

b8f262699f git-mv: fix directory separator treatment on Windows
The following invocations did not work as expected on Windows:

    git mv foo\bar dest
    git mv foo\ dest

The first command was interpreted as

    git mv foo/bar dest/foo/bar

because the Windows style directory separator was not obeyed when the
basename of 'foo\bar' was computed.

The second command failed because the Windows style directory separator was
not removed from the source directory, whereupon the lookup of the
directory in the index failed.

This fixes both issues by using is_dir_sep() and basename().

b8e8db281c git log: add '--merges' flag to match '--no-merges'
I do various statistics on git, and one of the things I look at is merges,
because they are often interesting events to count ("how many merges vs
how much 'real development'" kind of statistics). And you can do it with
some fairly straightforward scripting, ie

	git rev-list --parents HEAD |
		grep ' .* ' |
		git diff-tree --always -s --pretty=oneline --stdin |
		less -S

will do it.

But I finally got irritated with the fact that we can skip merges with
'--no-merges', but we can't do the trivial reverse operation.

So this just adds a '--merges' flag that _only_ shows merges. Now you can
do the above with just a

	git log --merges --pretty=oneline

which is a lot simpler. It also means that we automatically get a lot of
statistics for free, eg

	git shortlog -ns --merges

does exactly what you'd want it to do.

This argument is required if there are multiple branches (or tags) entries

specifies which branch (or tag) path to use to create the branch (or tag).

5eec27e35f git-svn: let 'dcommit $rev' work on $rev instead of HEAD
'git svn dcommit' takes an optional revision argument, but the meaning
of it was rather scary.  It completely ignored the current state of
the HEAD, only looking at the revisions between SVN and $rev.  If HEAD
was attached to $branch, the branch lost all commits $rev..$branch in
the process.

Considering that 'git svn dcommit HEAD^' has the intuitive meaning
"dcommit all changes on my branch except the last one", we change the
meaning of the revision argument.  git-svn temporarily checks out $rev
for its work, meaning that

* if a branch is specified, that branch (_not_ the HEAD) is rebased as
  part of the dcommit,

* if some other revision is specified, as in the example, all work
  happens on a detached HEAD and no branch is affected.
