This reworks the way that the "Find" button (and the /, ?, ^F, and ^G
keys) works. Previously, pressing the "Find" button would cause gitk
to go off and scan through every commit to see which commits matched,
and the user interface was completely unreponsive during that time.
Now the searching is done in chunks using the scheduler, so the UI
still responds, and the search stops as soon as a matching commit is
found.
The highlighting of matches using a yellow background is now done in
the commit-drawing code and the highlighting code. This ensures that
all the commits that are visible that match are highlighted without
the search code having to find them all.
This also fixes a bug where previously-drawn commits that need to be
highlighted were not being highlighted.

Since git reset now gets chatty while resetting, we were getting errors
reported when a reset was done using the "reset branch to here" menu
item. With this we now read the progress messages from git reset and
update a progress bar. Because git reset outputs the progress messages
to standard error, and Tcl treats messages to standard error as error
messages, we have to invoke git reset via a shell and redirect standard
error into standard output.
This also fixes a bug in computing descendent heads when head ids
are changed via a reset.

The main thing here is better parsing of the diff --git lines in the
output of git diff-tree -p. We now cope with filenames in quotes with
special chars escaped. If the filenames contain spaces they aren't
quoted, however, which can create difficulties in parsing. We get
around the difficulties by detecting the case when the filename hasn't
changed (chop the part after "diff --git " in two and see if the halves
match apart from a/ in one and b/ in the other), and if it hasn't
changed, we just use one half. If the filename has changed we wait
for the "rename from" and "rename to" lines, which give the old and
new filenames unambiguously.
This also improves the parsing of the output of git diff-tree.
Instead of using lindex to extract the filename, we take the part from
the first tab on, and if it starts with a quote, we use [lindex $str 0]
to remove the quotes and convert the escapes.
This also gets rid of some unused tagging of the diff text, uses
[string compare] instead of [regexp] in some places, and fixes the
regexp for detecting the @@ hunk-separator lines (the regexp wasn't
accepting a single number, as in "-0,0 +1" for example).

When we compute descendent heads and descendent/ancestor tags, we

when we add stuff to the graph. Also make sure that when we cache
descendent heads for a node we only cache the heads that are actually
descendents of that node.

For some unknown reason, changing the scrolling region on the canvases

We were doing two execs for each tag - one to map the tag ID to a
commit ID and one to read the contents of the tag for later display.
This speeds up the process by not reading the contents of the tag
(instead it is read later if needed), and by using the -d flag to
git show-ref, which gives us refs/tags/foo^{} lines which give us
the commit ID. Also this uses string operations instead of regexps.

If there are local changes in the repository, i.e., git-diff-index HEAD
produces some output, then this optionally displays an extra row in
the graph as a child of the HEAD commit (but with a red circle to
indicate that it's not a real commit). There is a checkbox in the
preferences window to control whether gitk does this or not.
Clicking on the extra row shows the diffs between the working directory
and the HEAD (using git diff-index -p). The right-click menu on the
extra row allows the user to generate a patch containing the local diffs,
or to display the diffs between the working directory and any commit.

This only draws as much of the graph lines as is visible. This can
happen by adding coordinates on to an existing graph line or by
creating a new line. This means that we only need to have laid out
and optimized as much of the graph as is actually visible in order to
draw it, including the lines (previously we didn't draw a graph
line until we had laid out and optimized to the end of a segment of
the line, i.e. down to a down-arrow or to the row where the line's
commit is displayed). This also lets us get rid of the linesegends
list, and gives us an easy workaround for the X server bug that
causes long lines to be misdrawn. This also gets rid of the use
of rowoffsets in drawlineseg et al.

This removes the need for insertrow to go through rowrangelist and
idrowranges and adjust a lot of entries. The first entry for a given
id is now the row number of the first child, not that row number + 1,
and rowranges compensates for that so its callers didn't have to
change. This adds a ranges argument to drawlineseg so that we can
avoid calling rowranges a second time inside drawlineseg (all its
callers already called rowranges).

This allows us to do compute-intensive processing, such as laying out
the graph, relatively efficiently while also having the GUI be
reasonably responsive. The problem previously was that file events
were serviced before X events, so reading from another process which
supplies data quickly (hi git rev-list :) could mean that X events
didn't get processed for a long time.
With this, gitk finishes laying out the graph slightly sooner and
still responds to the GUI while doing so.

With some large repositories, a commit can end up on thousands of
branches, which results in an extremely long "Branches:" line in the
details window, and that results in the window being extremely slow
to scroll.
This fixes it by just showing "many (N)" after "Branches:", "Follows:"
or "Precedes:", where N is the number of heads or tags. The limit
is currently set at 20 but could be made configurable (and the "many"
could be a link to pop up a window listing them all in case anyone
really wants to know).

Instead of working out descendent heads and descendent & ancestor
branches in a two-pass algorithm, this reads and stores a simplified
version of the graph topology, and works out descendent/ancestor
tags and descendent heads on demand (with a bit of caching).
The advantages of this are, first, that we now don't have to use
--topo-order on the git rev-list process. Secondly, we don't have
to re-read the whole graph when tags or heads change or even when
the graph changes. Since we can cope with parents coming before
children, we can update the graph by running a git rev-list with
arguments that just give us the new commits, and merge the new
commits into the simplified graph.
The graph is simplified in the sense that commits with exactly one
parent and one child (which is >90% of them in most cases) are grouped
together into arcs joining nodes or 'branch/merge points', which are
the commits that don't have exactly 1 parent and 1 child. This reduces
the size of the graph substantially and decreases the time to traverse
it correspondingly.

Not all projects use the convention that one tabstop = 8 characters, and

Subtle bugs remained on both Cygwin and Linux that caused the various
window panes to be restored in positions different than where the user
last placed them. Sergey Vlasov posed a pair of suggested fixes to this,
what is done here is slightly different. The basic fix here involves
a) explicitly remembering and restoring the sash positions for the upper
window, and b) using paneconfigure to redundantly set height and width of
other elements. This redundancy is needed as Cygwin Tcl has a nasty habit
of setting pane sizes to zero if their slaves are not configured with a
specific size, but Linux Tcl does not honor the specific size given.

gitk was saving widget sizes and positions when the main window was
destroyed, which is after all child widgets are destroyed. The cure
is to trap the WM_DELETE_WINDOW event before the gui is torn down. Also,
the saved geometry was captured using "winfo geometry .", rather than
"wm geometry ." Under Linux, these two return different answers and the
latter one is correct.
[jc: credit goes to Brett Schwarz for suggesting the use of "wm protocol";

The gitk gui layout was completely broken on Cygwin. If gitk was started
without previous geometry in ~/.gitk, the user could drag the window sashes
to get a useable layout. However, if ~/.gitk existed, this was not possible
at all.
The fix was to rewrite makewindow, changing the toplevel containers and
the particular geometry information saved between sessions. Numerous bugs
in both the Cygwin and the Linux Tk versions make this a delicate
balancing act: the version here works in both but many subtle variants
are competely broken in one or the other environment.
Three user visible changes result:
1 - The viewer is fully functional under Cygwin.
2 - The search bar moves from the bottom to the top of the lower left
pane. This was necessary to get around a layout problem on Cygwin.
3 - The window size and position is saved and restored between sessions.
Again, this is necessary to get around a layout problem on Cygwin.
