When "git checkout-index" checks out path A/B/C, it makes sure A
and A/B are truly directories; if there is a regular file or
symlink at A, we prefer to remove it.
We used to do this by catching an error return from mkdir(2),
and on EEXIST did unlink(2), and when it succeeded, tried
another mkdir(2).
Thomas Glanzmann found out the above does not work on Solaris
for a root user, as unlink(2) was so old fashioned there that it
allowed to unlink a directory.
As pointed out, this still doesn't guarantee that git won't call
"unlink()" on a directory (race conditions etc), but that's
fundamentally true (there is no "funlink()" like there is
"fstat()"), and besides, that is in no way git-specific (ie it's
true of any application that gets run as root).

Showing only five lines of heads/tags is not very useful to a user
when they have about 10 branches that match the filter expression.
The list is just too short to really be able to read easily, at
least not without scrolling up and down. Expanding the list out
to 10 really makes the revision picker easier to read and access,
as you can read the matching branches much more quickly.

We now allow users to pick which commit they want to browse through
our revision picking mega-widget. This opens up in a dialog first,
and then opens a tree browser for that selected commit. It is a very
simple approach and requires minimal code changes.
I also clarified the language a bit in the Repository menu, to show
that these actions will access files. Just in case a user is not
quite sure what specific action they are looking for, but they know
they want some sort of file thing.

A long time ago Linus Torvalds tried to run git-gui on a bare
repository to look at the blame viewer, but it failed to start
because we required that the user run us only from within a
working directory that had a normal git repository associated
with it.
This change relaxes that requirement so that you can start the
tree browser or the blame viewer against a bare repository. In
the latter case we do require that you provide a revision and a
pathname if we cannot find the pathname in the current working
directory.

I'm moving the code related to looking to see if we should GC now
into a procedure closer to where it belongs, the database module.
This reduces our script by a few lines for the single commit case
(aka citool). But really it just is to help organize the code.
We now perform the check after we have been running for at least
1 second. This way the main window has time to open up and our
dialog (if we open it) will attach to the main window, instead of
floating out in no-mans-land like it did before on Mac OS X.
I had to use a wait of a full second here as a wait of 1 millisecond
made our console install itself into the main window. Apparently we
had a race condition with the console code where both the console and
the main window thought they were the main window.

Some users may do odd things, like tag their own private version of
Git with an annotated tag such as 'testver', then compile that git
and try to use it with git-gui. In such a case `git --version` will
give us 'git version testver', which is not a numeric argument that
we can pass off to our version comparsion routine.
We now check that the cleaned up git version is a going to pass the
version comparsion routine without failure. If it has a non-numeric
component, or lacks at least a minor revision then we ask the user to
confirm they really want to use this version of git within git-gui.
If they do we shall assume it is git 1.5.0 and run with only the code
that will support.

Instead of running a full git-count-objects to count all of the loose
objects we can get a reasonably close approximation by counting the
number of files in the .git/objects/42 subdirectory. This works out
reasonably well because the SHA-1 hash has a fairly even distribution,
so every .git/objects/?? subdirectory should get a relatively equal
number of files. If we have at least 8 files in .git/objects/42 than it
is very likely there is about 8 files in every other directory, leaving
us with around 2048 loose objects.
This check is much faster, as we need to only perform a readdir of
a single directory, and we can do it directly from Tcl and avoid the
costly fork+exec.
All of the credit on how clever this is goes to Linus Torvalds; he
suggested using this trick in a post commit hook to repack every so
often.

If we have more than our desired number of objects and we try to
open the "Do you want to repack now?" dialog we cannot include a
-parent . argument if the main window has not been mapped yet.
On Mac OS X it appears this window isn't mapped right away, so we
had better hang avoid including it.

On Windows (which includes Cygwin) Tcl defaults to leaving the EOF
character of input file streams set to the ASCII EOF character, but
if that character were to appear in the data stream then Tcl will
close the channel early. So we have to disable eofchar on Windows.
Since the default is disabled on all platforms except Windows, we
can just disable it everywhere to prevent any sort of read problem.

Renaming files with non-URI friendly characters caused
breakage when committing to DAV repositories (over http(s)).
Even if I try leaving out the $self->{url} from the return value
of url_path(), a partial (without host), unescaped path name
does not work.
Filenames for DAV repos need to be URI-encoded before being
passed to the library. Since this bug did not affect file://
and svn:// repos, the git-svn test library needed to be expanded
to include support for starting Apache with mod_dav_svn enabled.
This new test is not enabled by default, but can be enabled by
setting SVN_HTTPD_PORT to any available TCP/IP port on
127.0.0.1.
Additionally, for running this test, the following variables
(with defaults shown) can be changed for the suitable system.
The default values are set for Debian systems:
SVN_HTTPD_MODULE_PATH=/usr/lib/apache2/modules
SVN_HTTPD_PATH=/usr/sbin/apache2

Some source material (e.g. Subversion dump files) perform directory
renames by telling us the directory was copied, then deleted in the
same revision. This makes it difficult for a frontend to convert
such data formats to a fast-import stream, as all the frontend has
on hand is "Copy a/ to b/; Delete a/" with no details about what
files are in a/, unless the frontend also kept track of all files.
The new 'C' subcommand within a commit allows the frontend to make a
recursive copy of one path to another path within the branch, without
needing to keep track of the individual file paths. The metadata
copy is performed in memory efficiently, but is implemented as a
copy-immediately operation, rather than copy-on-write.
With this new 'C' subcommand frontends could obviously implement an
'R' (rename) on their own as a combination of 'C' and 'D' (delete),
but since we have already offered up 'R' in the past and it is a
trivial thing to keep implemented I'm not going to deprecate it.

In the previous behavior, "git-rm --cached" (without -f) had the same
restriction as "git-rm". This forced the user to use the -f flag in
situations which weren't actually dangerous, like:
$ git add foo # oops, I didn't want this
$ git rm --cached foo # back to initial situation
Previously, the index had to match the file *and* the HEAD. With
--cached, the index must now match the file *or* the HEAD. The behavior
without --cached is unchanged, but provides better error messages.

When I added the "--" case to the code scanning the arguments, I missed
the fact that since the switch statement uses -regexp, the "--" case
will match any argument containing "--", e.g. "--all". This fixes it
by taking out the -regexp (since we don't actually need regular
expression matching) and adjusting the match strings.
A side effect of this is that previously any argument starting with
"-d" would be taken to indicate date mode; now the argument has to be
exactly "-d" if you want date mode.
