Display the name of "this" repository rather than the quite ambiguous
string "This". The idea is that seeing the name of the directory the
repository is stored in should help jog the user's memory about what
they are setting options for.
Also place the options dialog immediately over the git-gui main window
when it gets opened. This way the user isn't scrolling very far away
to gain access to the window. At least on my Mac OS X system not doing
this makes the options dialog open rather far away, thus requiring lots
of mouse activity to reach it.

The git-update-index process can take a while to process a large
number of files; for example my laptop would probably need almost
an hour to chug through 20,000 modified files. In these incredibly

them know the application is still working on their behalf, even if
it won't them do anything else (as the index is locked).

This turned out to take a lot more time than I thought it would take;
but now users can edit the main UI font and the diff/fixed with font
by changing both the family name and/or the point size of the text.
We save the complete Tk font specification to the user's ~/.gitconfig
file upon saving options. This is probably more verbose than it needs
to be as there are many useless options recorded (e.g. -overstrike 0)
that a user won't really want to use in this application.

I decided that the options menu was going to turn into a mess after

including their --global options.
We also wisely let the user press Cancel (or destroy the window) to abort
any sort of option editing session, without the options being changed.

Apparently <Button-3> doesn't work on my single button PowerBook
mouse under Mac OS X. I'm guessing this is because Tk is stealing
every event and doesn't realize that Control-Button-1 is actually
supposed to invoke the context menu on this platform.
So now we have a utility procedure is_MacOSX to guess if we are
running on a Mac OS X system, and if so setup Control-Button-1 to
also activate what Button-3 should have. This does mean that I need
to stay away from using Control-Button-1 as a binding in any other
context. Of course we should use $M1B for that, which is M1 (aka
Command) on Mac OS X so that shouldn't prove to be a problem.

The native Tk font system is actually quite powerful and has the nice
property that modifications to a named font are immediately reflected
throughout all widgets currently displayed. This really saves us
from needing to write all of the reconfigure code as part of our font

I also fixed the way we detect and apply the system font on the main
UI widgets as although it worked on a Windows 2000 system it does not
work at all on my Mac OS 10.4 system.

When the user has enabled the Trust File Modification Timestamp option
then we may display a file as being modified yet that file may not have
a difference. When the user clicks on that file we wind up displaying
an empty diff viewer, which makes no sense to the user.
So instead if we get an empty diff and the user has this option enabled
and the file's current state is _M (no change in index but the working
file appears modified) then run a quick update-index on just that file
and remove it from the list of modified files. We also give the user
a quick dialog stating we are removing it, and why.
Usually I don't run into this situation when I have the Trust File
Modification Timestamp option enabled, so its not that annoying to
have a dialog pop open to remind me why there are no differences.

Because the diff area is one of the most important areas to be able to
read users should be able to increase or decrease the size of the font
used within that area.
Currently we save that back to the global configuration, even if it

is probably going to be considered to be a bug by at least one user
who wants some sort of different font within a given repository, but
I'm just going to ignore the problem for now.

The mouse cursor (at least on Windows) seemed to be picking up the
cursor from the sash controls and then never resetting itself back
to the standard text cursor (the I-beam) when it was over a text area
that the user can edit (like the commit buffer) or over a text area
the user can copy from (like the diff viewer).
So now we always set the cursor to left_ptr (which according to the Tk
documentation should be available everywhere) and only for the two text
areas which we use to list file names, as the user clicks in these but
is not permitted to select text.

The gui.geometry config value was starting to contain
the odd string \\{ as part of its value due to the
way the Tcl lists were being supplied to git repo-config.
Now we write out only three values: the overall window
geomtry, the y position of the horizontal sash, and
the x position of the vertical sash. All other data is
skipped, which makes the gui.geometry value simpler.
While debugging this I noticed that the save_my_config
procedure was being invoked multiple times during exit
due to do_quit getting invoked over and over again. So
now we set a flag in do_quit and don't perform any of our
"at exit" type of logic if we've already been through the

Rather than drawing our own toplevel for error messages we really

When we reshow the current diff file it can be faster to just fetch

When we commit we know that whatever was in the index went as part
of the commit. Since we generally assume that the user does not
update the index except through our user interface we can be reasonably
certain that any file which was marked as A/M/D in the index will have
had that A/M/D state changed to an _ (not different) by the commit.
We can use this knowledge to update the user interface post commit
by simply updating the index part of the file state of all files whose
index state was A/M/D to _ and then removing any file memory any which
wound up with a final state of __ (not different anywhere). Finally we
redraw the file lists and update the diff view.

If we are given a file whose path name contains an LF (\n) we now
escape it by inserting the common escape string \n instead of the

file, and it keeps the line numbers correct within the file lists.

When we did a rescan to update the file lists we lost the tag which
indicated which file was currently in the diff viewer. This occurs
because we delete every line from the two file list boxes (thus
removing the tag) and then redisplay the diff in the diff viewer
but then fail to restore the tag in the file list.
Now we restore that tag by searching for the file in the file lists
and adding the tag back when the diff viewer displays something.
We also no longer obtain the file path directly from the file list
text box. Instead we now keep two Tcl lists, one for each file list,
holding the file names in sorted order. These lists can be searched
with the native [lsearch -sorted] operation (which should be faster
than our crude bsearch) or can be quickly accessed by index to return
the file path. This should help make things safer should we ever be
given a file name which contains an LF within it (as that would span
two lines in the file list, not one).

If we load a message file (e.g. MERGE_MSG) or we have just finished
making a commit and are clearing out the commit buffer we should also
clear out the undo/redo stack associated with that buffer. The prior
undo/redo stack has no associated with the new content and therefore
is not useful to the user.
Also modified the sign-off operation to perform the entire update in
a single undo/redo operation, allowing the user to undo the signoff
in case they didn't actually want to do that.
I also noticed what may be a crash on Windows related to the up and
down arrow keys navigating within the diff viewer. Since I got back
no stack trace (just an application exit with a loss of the commit

If there are modified files present in the working directory then we
should not let the user perform a pull as it may fail due to the modified
files being uncommitted but needing to be merged at the file level.
Yes there are many cases where a merge will complete successfully even
though there are modified or untracked files sitting in the working
directory. But users generally shouldn't be attempting merges like that,
and if they are they probably are advanced enough to just use the command
line and bypass this little safety check.
We also no longer run a rescan after a successful pull has completed.
Usually this is unnecessary as a successful pull won't leave modified
files laying around. Instead we just update our HEAD and PARENT values
with the new commit, if there is one.
Unfortunately this does let the user get into an insane state as there
are bugs in core Git's git-pull and git-merge programs where the exit
status is sent back as a 0 rather than non-0 when a failure is detected.

On very large projects (~1000 files) on Windows systems the update-index
--refresh stage of the rescan process takes a nontrival amount of time.
If the user is generally very careful with their file modification such
that the modification timestamp of the file differs only when the content
also differs then we can skip this somewhat expensive step and go right
to the diff-index and diff-files processes.
We save the user's prefernce in the current repository if they modify the
setting during a git-gui session, but we also load it through our dump of
repo-config --list so the user could move it to their ~/.gitconfig file
if they wanted it globally disabled.
We still keep update-index --refresh enabled by default however, as most

Most users of git-gui probably shouldn't be invoking git repack directly;
instead we should be looking at how many loose objects they have and
how many active packs they have and making the decision for them. But
that's more work to code, and there's always going to be discussion about
what is the right default threshold and how do we know that the user is
willing to do the repack when we decide its time, etc.
So instead we'll just keep it simple and offer up the menu option.
Unfortunately right now we get now progress indication back from
git-pack-objects as its being invoked not through a tty, which makes
it disable progress output and the git-repack.sh wrapper won't let us

Since Tk will only supply new space gained from growing the top level to
the bottom/right most widget within a panedwindow and most users will be
growing a git-gui main window for the purposes of seeing more of the
currently shown diff, flipping the order around makes Tk do what the
user wants by default.
Of course because we also removed the paned window from the commit buffer
area it is now impossible to increase the visible space for the commit
message. But I don't see this as a huge concern right now as its actually
very awkward to try and balance three paned window dividers within the
same top level window. We could always add it back if users really want
to expand the commit buffer and see more.

Removed as much as possible from the merge_state proc, which is where
we spent most of our time before UI update. This change makes our
running time match that of git status, except that we then need about
7 additional seconds to draw 6900 files on screen.
Apparently the [array names a -exact $v] operator in Tcl is O(n) rather
than O(1), which is really quite disappointing given that each array can
only have one entry for a given value. Switching to a lookup with a
catch (whose error we ignore) runs in O(1) time and bought us most of
that improvement.

Loading 6900 newly added files required about 90 seconds on one system.
This is just far too long to perform a "status" type of operation.
git-status on the same system completes in just 8.2 seconds if it is
redirected to /dev/null.
Most of our performance improvement comes from moving all of the UI
updating out of the main fileevent handlers for the status process.
Instead we are only updating the file_states array and then only doing
the UI update when all states are known and have been finally determined.
The rescan execution is now down to almost 30 seconds for the same case,
a good (but not really all that impressive) improvement.

When we were receiving a lot of output from diff-index we split records
at the wrong locations and started using the file status information
(mode and SHA1s) as path names, and then proceeded to try to use part
of the path names as status data. This caused all sorts of havoc.
So I rewrote the parsing implementation to scan for the pair of null
bytes along the buffer and stop scanning (waiting for more data) if
both can't be found during this event. This seems to work well under
high load (like when processing 6,983 added files).
