28f8802417 Fix t6031 on filesystems without working exec bit
The point of the test is not really to test the ability of the
filesystem to keep the given x-bit, but to check is merge-recursive
correctly handles it.

16dd62ac4d git-gui: Add a --trace command line option
Often new Git users want to know what commands git-gui uses to make
changes, so they can learn the command line interface by mimicking
what git-gui does in response to GUI actions.  Showing the direct
commands being executed is easy enough to implement but this is of
little value to end-users because git-gui frequently directly calls
plumbing, not porcelain.

Since the code is already written and tested, its fairly harmless
to include.  It may not help a new end-user, but it can help with
debugging git-gui or reverse-engineering its logic to further make
changes to it or implement another GUI for Git.

94b4a69f75 gitk: Fix bug where current row number display stops working
The display of the current row number would stop working if the user
clicked on a line, or if selectedline got unset for any other reason,
because the trace on it got lost when it was unselected.  This fixes
it by changing the places that unset selectedline to set it to the
empty string instead, and the places that tested for it being set or
unset to compare it with the empty string.  Thus it never gets unset
now.  This actually simplified the code in a few places since it can
be compared for equality with a row number now without first testing
if it is set.

8ccba008ee unpack-trees: allow Porcelain to give different error messages
The plumbing output is sacred as it is an API.  We _could_ change it if it
is broken in such a way that it cannot convey necessary information fully,
but we just do not _reword_ for the sake of rewording.  If somebody does
not like it, s/he is complaining too late.  S/he should have been here in
early May 2005 and make the language used by the API closer to what humans
read.  S/he wasn't here.  Too bad, and it is too late.

And people who complain should look at a bigger picture.  Look at what was
suggested by one of them and think for five seconds:

     $ git checkout mytopic
    -fatal: Entry 'frotz' not uptodate. Cannot merge.
    +fatal: Entry 'frotz' has local changes. Cannot merge.

If you do not see something wrong with this output, your brain has already
been rotten with use of git for too long a time.  Nobody asked us to
"merge" but why are we talking about "Cannot merge"?

This patch introduces a mechanism to allow Porcelains to specify messages
that are different from the ones that is given by the underlying plumbing
implementation of read-tree, so that we can reword the message Porcelains give
without disrupting the output from the plumbing.

    $ git-checkout pu
    error: You have local changes to 'Makefile'; cannot switch branches.

There are other places that ask unpack_trees() to n-way merge, detect
issues  and let it issue error message on its own, but I did this as a
demonstration and replaced only one message.

Yes I know about C99 structure initializers.  I'd love to use them but we
try to be nice to compilers without it.

032bea55a3 builtin-apply: do not declare patch is creation when we do not know it
When we see no context nor deleted line in the patch, we used to declare
that the patch creates a new file.  But some people create an empty file
and then apply a patch to it.  Similarly, a patch that delete everything
is not a deletion patch either.

This commit corrects these two issues.  Together with the previous commit,
it allows a diff between an empty file and a line-ful file to be treated
as both creation patch and "add stuff to an existing empty file",
depending on the context.  A new test t4126 demonstrates the fix.

5c47f4c6e7 builtin-apply: accept patch to an empty file
A patch from a foreign SCM (or plain "diff" output) often have both
preimage and postimage filename on ---/+++ lines even for a patch that
creates a new file.  However, when there is a filename for preimage, we
used to insist the file to exist (either in the work tree and/or in the
index).  When we cannot be sure by parsing the patch that it is not a
creation patch, we shouldn't complain when if there is no such a file.
This commit fixes the logic.

Refactor the code that validates the preimage file into a separate
function while we are at it, as it is getting rather big.

1. Temporary empty working directory (with index) for certain operations

2. Use a temporary directory with temporary file names for doing
   merges of user's dirty sandbox state with latest changes in
   repository.
3. Coming up soon: Set up an index and either a valid or empty
   working directory when calling git-check-attr to decide
   if a file should be marked binary (-kb).

d775734c40 cvsexportcommit: introduce -W for shared working trees (between Git and CVS)
If you have a CVS checkout, it is easy to import the CVS history by
calling "git cvsimport".  However, interacting with the CVS repository
using "git cvsexportcommit" was cumbersome, since that script assumes
separate working directories for Git and CVS.

Now, you can call cvsexportcommit with the -W option.  This will
automatically discover the GIT_DIR, and it will check out the parent
commit before exporting the commit.

The intended workflow is this:

$ CVSROOT=$URL cvs co module
$ cd module
$ git cvsimport
hack, hack, hack, making two commits, cleaning them up using rebase -i.
$ git cvsexportcommit -W -c -p -u HEAD^
$ git cvsexportcommit -W -c -p -u HEAD

6848d58c60 Ignore dirty submodule states during rebase and stash
When rebasing or stashing, chances are that you do not care about
dirty submodules, since they are not updated by those actions anyway.
So ignore the submodules' states.

Note: the submodule states -- as committed in the superproject --
will still be stashed and rebased, it is _just_ the state of the
submodule in the working tree which is ignored.

Why?  Sometimes it is not interesting when a submodule changed.

57e0e3ebd6 cvsexportcommit: chomp only removes trailing whitespace
In commit fef3a7cc(cvsexportcommit: be graceful when "cvs status"
reorders the arguments), caution was taken to get the status even
for files with leading or trailing whitespace.

However, the author of that commit missed that chomp() removes only
trailing newlines.  With help of the mailing list, the author realized
his mistake and provided this patch.

The idea is that we do not want to rely on a certain layout of the
output of "cvs status".  Therefore we only call it with files that are
unambiguous after stripping leading and trailing whitespace.

ca11b212eb let pack-objects do the writing of unreachable objects as loose objects
Commit ccc1297226b184c40459e9d373cc9eebfb7bd898 changed the behavior
of 'git repack -A' so unreachable objects are stored as loose objects.
However it did so in a naive and inn efficient way by making packs
about to be deleted inaccessible and feeding their content through
'git unpack-objects'.  While this works, there are major flaws with
this approach:

- It is unacceptably sloooooooooooooow.

  In the Linux kernel repository with no actual unreachable objects,
  doing 'git repack -A -d' before:

	real    2m33.220s
	user    2m21.675s
	sys     0m3.510s

  And with this change:

	real    0m36.849s
	user    0m24.365s
	sys     0m1.950s

  For reference, here's the timing for 'git repack -a -d':

	real    0m35.816s
	user    0m22.571s
	sys     0m2.011s

  This is explained by the fact that 'git unpack-objects' was used to
  unpack _every_ objects even if (almost) 100% of them were thrown away.

- There is a black out period.

  Between the removal of the .idx file for the redundant pack and the
  completion of its unpacking, the unreachable objects become completely
  unaccessible.  This is not a big issue as we're talking about unreachable
  objects, but some consistency is always good.

- There is no way to easily set a sensible mtime for the newly created
  unreachable loose objects.

So, while having a command called "pack-objects" to perform object
unpacking looks really odd, this is probably the best compromize to be
able to solve the above issues in an efficient way.

bbac73117e add a force_object_loose() function
This is meant to force the creation of a loose object even if it
already exists packed.  Needed for the next commit.

0bdf93cbf0 filter-branch: fix variable export logic
filter-branch tries to restore "old" copies of some
environment variables by using the construct:

  unset var
  test -z "$old_var" || var="$old_var" && export var

This is just wrong.  AND-list and OR-list operators && and || have equal
precedence and they bind left to right.  The second term, var="$old"
assignment always succeeds, so we always end up exporting var.

On bash and dash, exporting an unset variable has no effect. However, on
some shells (such as FreeBSD's /bin/sh), the shell exports the empty
value.

This manifested itself in this case as git-filter-branch setting
GIT_INDEX_FILE to the empty string, which in turn caused its call to
git-read-tree to fail, leaving the working tree pointing at the original
HEAD instead of the rewritten one.

To fix this, we change the short-circuit logic to better match the intent:

  test -z "$old_var" || {
    var="$old_var" && export var
  }
