Consecutive chunks of a file could come from the same commit, but
have different original file names. Previously we would have put
them into a single group, but then the hyperlink would jump to only
one of the files, and the other would not be accessible. Now we can
get to the other file too.

gitweb has long had a feature where the user can click on any
commit the blame display and go visit that commit's information
page. From the user could go get the blame display for the file
they are tracking, and try to digg through the history of any
part of the code they are interested in seeing.
We now offer somewhat similiar functionality in git-gui. The 4
digit commit abreviation in the first column of our blame view is
now offered as a hyperlink if the commit isn't the one we are now
viewing the blame output for (as there is no point in linking back
to yourself). Clicking on that link will stop the current blame
engine (if still running), push the new target commit onto the
history stack, and restart the blame viewer at that commit, using
the "original file name" as supplied by git-blame for that chunk
of the output.
Users can navigate back to a version they had been viewing before
by way of a back button, which offers the prior commits in a popup
menu displayed right below the back button. I'm always showing the
menu here as the cost of switching between views is very high; you
don't want to jump to a commit you are not interested in looking at
again.
During switches we throw away all data except the cached commit data,
as that is relatively small compared to most source files and their
annotation marks. Unfortunately throwing this per-file data away in
Tcl seems to take some time; I probably should move the line indexed
arrays to proper lists and use [lindex] rather than the array lookup
(usually lists are faster).
We now start the git-blame process using "nice", so that its priority
will drop hopefully below our own. If I don't do this the blame engine
gets a lot of CPU under Windows 2000 and the git-gui user interface is
almost non-responsive, even though Tcl is just sitting there waiting
for events.

Computing the blame records for a large file with a long project
history can take git a while to run; traditionally we have shown
a little meter in the status area of our blame viewer that lets
the user know how many lines have been finished, and how far we
are through the process.
Usually such progress indicators are drawn with a little progress
bar in the window, where the bar shows how much has been completed
and hides itself when the process is complete. I'm using a very
simple hack to do that: draw a canvas with a filled rectangle.
Of course the time remaining has absolutely no relationship to the
progress meter. It could take very little time for git-blame to get
the first 90% of the file, and then it could take many times that to
get the remaining 10%. So the progress meter doesn't really have any
sort of assurances that it relates to the true progress of the work.
But in practice on some ugly history it does seem to hold a reasonable
indicator to the completion status. Besides, its amusing to watch and
that keeps the user from realizing git is being somewhat slow.

At one point I tried to present the blame viewer to an audience of
people on a 640 by 480 pixel LCD projector. This did not work at
all as the top area (the file data) was taking up all of the screen
realestate and the split point was not adjustable by the user. In
general locking the user into a specific ratio of display is just
not user friendly.
So we now place a split pane control into the middle of our blame
window, so the user can adjust it to their current needs. If the
window increases (or decreases) in height we assign the difference
to the file data area, as that is generally the area of the window
that users are trying to see more of when they grow the window.
Unfortunately there appears to be a bug in the "pack" layout manager
in Tcl/Tk 8.4.1. The status bar and the lower commit pane was being
squashed if the window decreased in height. I think the pack manager
was just not decreasing the size of the panedwindow slave properly if
the main window shrank. Switching to the "grid" layout manager fixes
the problem, but is slightly uglier setup code.

Frequently when I'm looking at blocks of code in the blame
viewer I want to know who is the culprit, or who I should
be praising for a job well done. The tooltips nicely show
this if I mouse over a block, but it doesn't work to get
this detail at a glance.
Since we don't use the leftmost commit column for anything
after the first line within a commit group I'm now tossing
the author's initials into that field, right justified. It
is quite clearly not a SHA-1 number as we always show the
SHA-1 in lowercase, while we explicitly select only the
uppercase characters from an author's name field, and only
those that are following whitespace.
I'm using initials here over anything else as they are quite
commonly unique within small development teams. The leading
part of the email address field was out for some of the teams
I work with, as there the email addresses are all of the form
"Givenname.Surname@initech.com". That will never fit into the
4 characters available.

If two consecutive lines in the final file came from the same commit
then we store a "|" in the first column rather than the commit id,
for the second and subsequent lines in that block. This cleans up
the interface so runs associated with the same commit can be more
easily seen visually.
We also now use the abbreviation "work" for the uncommitted stuff in
your working directory, rather than "0000". This looks nicer to the
eyes and explains pretty quickly what is going on.
There was also a minor bug in the commit abbreviation column for the
last line of the file. This is now also fixed.

The git-gui blame viewer has always been ugly as s**t. Linus Torvalds
suggested the coloring scheme I'm using here, which is two different
shades of grey for the background colors, and black text on a pale green
background for the currently selected/focused commit.
The difference is a massive improvement. The interface no longer will
cause seizures in people who are prone to that sort of thing. It no
longer uses a very offensive hot pink. The green being current actually
makes sense. And not having the background of the other non-current
lines change when you change the current commit is really a big deal.

To improve performance on fork+exec impoverished systems (such as
Windows) we want to avoid running git-symbolic-ref on every rescan

Git has supported remote branch deletion for quite some time, but
I've just never gotten around to supporting it in git-gui. Some
workflows have users push short-term branches to some remote Git
repository, then delete them a few days/weeks later when that topic
has been fully merged into the main trunk. Typically in that style
of workflow the user will want to remove the branches they created.
We now offer a "Delete..." option in the Push menu, right below the
generic "Push..." option. When the user opens our generic delete
dialog they can select a preconfigured remote, or enter a random
URL. We run `git ls-remote $url` to obtain the list of branches and
tags known there, and offer this list in a listbox for the user to
select one or more from.
Like our local branch delete dialog we offer the user a way to filter
their selected branch list down to only those branches that have been
merged into another branch. This is a very common operation as the
user will likely want to select a range of topic branches, but only
delete them if they have been merged into some sort of common trunk.
Unfortunately our remote merge base detection is not nearly as strict
as the local branch version. We only offer remote heads as the test
commit (not any local ones) and we require that all necessary commits
to successfully run git-merge-base are available locally. If one or
more is missing we suggest that the user run a fetch first.
Since the Git remote protocol doesn't let us specify what the tested
commit was when we evaluated our decision to execute the remote delete
there is a race condition here. The user could do a merge test against
the trunk, determine a topic branch was fully merged, but before they
can start pushing the delete request another user could fast-forward
the remote topic branch to a new commit that is not merged into the
trunk. The delete will arrive after, and remove the topic, even though
it was not fully merged.

Git's native command line interface has had branch renaming
support for quite a while, through the -m/-M options to the
git-branch command line tool. This is an extremely useful
feature as users may decide that the name of their current
branch is not an adequate description, or was just entered
incorrectly when it was created.
Even though most people would consider git-branch to be a
Porcelain tool I'm using it here in git-gui as it is the
only code that implements the rather complex set of logic
needed to successfully rename a branch in Git. Currently
that is along the lines of:
*) Backup the ref
*) Backup the reflog
*) Delete the old ref
*) Create the new ref
*) Move the backed up reflog to the new ref
*) Record the rename event in the reflog
*) If the current branch was renamed, update HEAD
*) If HEAD changed, record the rename event in the HEAD reflog
*) Rename the [branch "$name"] section in the config file
Since that is some rather ugly set of functionality to implement
and get right, and some of it isn't easily accessible through the
raw plumbing layer I'm just cheating by relying on the Porcelain.

In some workflows it is common for a large number of temporary
branches to be created in a remote repository, get fetched to
clients that typically only use git-gui, and then later have
those branches deleted from the remote repository once they have
been fully merged into all destination branches. Users of git-gui
would obviously like to have their local tracking branches cleaned
up for them, otherwise their local tracking branch namespace would
grow out of control.
The best known way to remove these tracking branches is to run
"git remote prune <remotename>". Even though it is more of a
Porcelain command than plumbing I'm invoking it through the UI,
because frankly I don't see a reason to reimplement its ls-remote
output filtering and config file parsing.
A new configuration option (gui.pruneduringfetch) can be used to
automatically enable running "git remote prune <remotename>" after
the fetch of that remote also completes successfully. This is off
by default as it require an additional network connection and is
not very fast on Cygwin if a large number of tracking branches have
been removed (due to the 2 fork+exec calls per branch).

Johannes Sixt asked me to try to avoid embedding the runtime location
of git-gui's library directory in the executable script. Not embedding
it helps the MinGW to be relocatable to another directory should a user
wish to install the programs in a directory other than the location the
packager wanted them to be installed into.
Most of this is a hack. We try to determine if the path of our master
git-gui script will be able to locate the lib by ../share/git-gui/lib.
This should be true if $(gitexecdir) and $(libdir) have the same prefix.
If they do then we defer the assignment of $(libdir) until runtime, and
we get it from $argv0 rather than embedding it into the script itself.

The tclIndex is required for git-gui to load its associated lib files,
