2ff3a80334 Teach --dirstat not to completely ignore rearranged lines within a file
Currently, the --dirstat analysis ignores when lines within a file are
rearranged, because the "damage" calculated by show_dirstat() is 0.
However, if the object name has changed, we already know that there is
some damage, and it is unintuitive to claim there is _no_ damage.

Teach show_dirstat() to assign a minimum amount of damage (== 1) to
entries for which the analysis otherwise yields zero damage, to still
represent that these files are changed, instead of saying that there
is no change.

Also, skip --dirstat analysis when the object names are the same (e.g. for
a pure file rename).

642f85faab i18n: avoid parenthesized string as array initializer
The syntax

    static const char ignore_error[] = ("something");

is invalid C.  A parenthesized string is not allowed as an array
initializer.

Some compilers, for example GCC and MSVC, allow this syntax as an
extension, but it is not a portable construct.  tcc does not parse it, for
example.

Remove the parenthesis from the definition of the N_() macro to
fix this.

0133dab75d --dirstat-by-file: Make it faster and more correct
Currently, when using --dirstat-by-file, it first does the full --dirstat
analysis (using diffcore_count_changes()), and then resets 'damage' to 1,
if any damage was found by diffcore_count_changes().

But --dirstat-by-file is not interested in the file damage per se. It only
cares if the file changed at all. In that sense it only cares if the blob
object for a file has changed. We therefore only need to compare the
object names of each file pair in the diff queue and we can skip the
entire --dirstat analysis and simply set 'damage' to 1 for each entry
where the object name has changed.

This makes --dirstat-by-file faster, and also bypasses --dirstat's practice
of ignoring rearranged lines within a file.

The patch also contains an added testcase verifying that --dirstat-by-file
now detects changes that only rearrange lines within a file.

12a296bca3 git-svn: Add a svn-remote.<name>.pushurl config key
Similar to the 'remote.<name>.pushurl' config key for git remotes,
'pushurl' is designed to be used in cases where 'url' points to an SVN
repository via a read-only transport, to provide an alternate
read/write transport. It is assumed that both keys point to the same
repository.

The 'pushurl' key is distinct from the 'commiturl' key in that
'commiturl' is a full svn path while 'pushurl' (like 'url') is a base
path. 'commiturl' takes precendece over 'pushurl' in cases where
either might be used.

The 'pushurl' is used by git-svn's dcommit and branch commands.

4e8115fff1 merge: allow "-" as a short-hand for "previous branch"

conveniently switch back to the previous branch, "git merge -" is a
short-hand for "git merge @{-1}" to conveniently merge the previous branch.

It will allow me to say:

    $ git checkout -b au/topic

b961219779 upload-pack: start pack-objects before async rev-list
In a pthread-enabled version of upload-pack, there's a race condition
that can cause a deadlock on the fflush(NULL) we call from run-command.

What happens is this:

  1. Upload-pack is informed we are doing a shallow clone.

  2. We call start_async() to spawn a thread that will generate rev-list
     results to feed to pack-objects. It gets a file descriptor to a
     pipe which will eventually hook to pack-objects.

  3. The rev-list thread uses fdopen to create a new output stream
     around the fd we gave it, called pack_pipe.

  4. The thread writes results to pack_pipe. Outside of our control,
     libc is doing locking on the stream. We keep writing until the OS
     pipe buffer is full, and then we block in write(), still holding
     the lock.

  5. The main thread now uses start_command to spawn pack-objects.
     Before forking, it calls fflush(NULL) to flush every stdio output
     buffer. It blocks trying to get the lock on pack_pipe.

And we have a deadlock. The thread will block until somebody starts
reading from the pipe. But nobody will read from the pipe until we
finish flushing to the pipe.

To fix this, we swap the start order: we start the
pack-objects reader first, and then the rev-list writer
after. Thus the problematic fflush(NULL) happens before we
even open the new file descriptor (and even if it didn't,
flushing should no longer block, as the reader at the end of
the pipe is now active).

e0e2a9cbfa stash: drop dirty worktree check on apply
Before we apply a stash, we make sure there are no changes
in the worktree that are not in the index. This check dates
back to the original git-stash.sh, and is presumably
intended to prevent changes in the working tree from being
accidentally lost during the merge.

However, this check has two problems:

  1. It is overly restrictive. If my stash changes only file
     "foo", but "bar" is dirty in the working tree, it will
     prevent us from applying the stash.

  2. It is redundant. We don't touch the working tree at all
     until we actually call merge-recursive. But it has its
     own (much more accurate) checks to avoid losing working
     tree data, and will abort the merge with a nicer
     message telling us which paths were problems.

So we can simply drop the check entirely.

59d418fe10 stash: fix accidental apply of non-existent stashes
Once upon a time, "git rev-parse ref@{9999999}" did not
generate an error. Therefore when we got an invalid stash
reference in "stash apply", we could end up not noticing
until quite late.  Commit b0f0ecd (detached-stash: work
around git rev-parse failure to detect bad log refs,
2010-08-21) handled this by checking for the "Log for stash
has only %d entries" warning on stderr when we validated the
ref.

A few days later, e6eedc3 (rev-parse: exit with non-zero
status if ref@{n} is not valid., 2010-08-24) fixed the
original issue. That made the extra stderr test superfluous,
but also introduced a new bug. Now the early call to:

  git rev-parse --symbolic "$@"

fails, but we don't notice the exit code. Worse, its empty
output means we think the user didn't provide us a ref, and
we try to apply stash@{0}.

This patch checks the rev-parse exit code and fails early in
the revision parsing process. We can also get rid of the
stderr test; as a bonus, this means that "stash apply" can
now run under GIT_TRACE=1 properly.

9db31bdf5c submodule: Add --force option for git submodule update
By default git submodule update runs a simple checkout on submodules that
are not up-to-date. If the submodules contains modified or untracked
files, the command may exit sanely with an error:

  $ git submodule update
  error: Your local changes to the following files would be overwritten by
  checkout:
	  file
  Please, commit your changes or stash them before you can switch branches.
  Aborting
  Unable to checkout '1b69c6e55606b48d3284a3a9efe4b58bfb7e8c9e' in
  submodule path 'test1'

In order to reset a whole git submodule tree, a user has to run first 'git
submodule foreach --recursive git checkout -f' and then run 'git submodule
update'.

This patch adds a --force option for the update command (only used for
submodules without --rebase or --merge options). It passes the --force
option to git checkout which will throw away the local changes.

8c8674fc95 pull: do not clobber untracked files on initial pull
For a pull into an unborn branch, we do not use "git merge"
at all. Instead, we call read-tree directly. However, we
used the --reset parameter instead of "-m", which turns off
the safety features.
