This effectively coaelesces the highlighting function and the search
function. Instead of separate highlight and find controls, there is
now one set of interface elements that controls both. The main
selector is a drop-down menu that controls whether commits are
highlighted and searched for on the basis of text in the commit
(i.e. the commit object), files affected by the commit or strings
added/removed by the commit.
The functions to highlight by membership of a view or by ancestor/
descendent relation to the selected commit are gone, as is the
move to next/previous highlighted commit (shift-up/down) function.

This adds code to write out the topology information used to determine
precedes/follows and branch information into a cache file (~3.5MB for
the kernel tree). At startup we read the cache file and then do a
git rev-list to update it, which is fast because we exclude all commits
in the cache that have no children and commits reachable from them
(which amounts to everything in the cache). If one of those commits
without children no longer exists, then git rev-list will give an error,
whereupon we throw away the cache and read in the whole tree again.
This gives a significant speedup in the startup time for gitk.

This changes layoutrows and optimize_rows to make it possible to lay
out only a little bit more of the graph than is visible, rather than
having to lay out the whole graph from top to bottom. To lay out
some of the graph without starting at the top, we use the new make_idlist
procedure for the first row, then lay it out proceeding downwards
as before. Empty list elements in rowidlist are used to denote rows
that haven't been laid out yet.
Optimizing happens much as before except that we don't try to optimize
unless we have three consecutive rows laid out (or the top 2 rows).
We have a new list, rowisopt, to record which rows have been optimized.
If we change a row that has already been drawn, we set a flag which
causes drawcommits to throw away everything drawn on the canvas and redraw
the visible rows.

First, this fixes the problem where a SHA1 id wouldn't be displayed
as a link if it wasn't in the part of the graph that had been laid
out at the time the details pane was filled in, even if that commit
later became part of the graph. This arranges for us to turn the
SHA1 id into a link when we get to that id in laying out the graph.
Secondly, there was a problem where the cursor wouldn't always turn
to a hand when over a link, because the areas for two links could
overlap slightly. This fixes that by using a counter rather than
always reverting to a counter when we leave the region of a link
(which can happen just after we've entered a different link).

This changes layoutrows to use information from rowidlist and children

idpending array that is updated and used by getcommitlines.
This also fixes a bug where we weren't resetting the ordertok array when

Instead make the rowranges procedure compute its result by looking

The way gitk used to draw the lines joining a commit to the lines
representing its parents was sometimes visually ambiguous, especially
when the line to the parent had a corner that coincided with a corner
on another line.
This improves things by using a smaller slanting section on the line
joining a commit to a parent line if the parent line is vertical where
it joins on. It also optimizes the drawing a little in the case where
the parent line slants towards this commit already.

This creates an "ordering token" for each commit which establishes
a total ordering for commits and is used to order the commits from
left to right on a row. The ordering token is assigned when a commit
is first encountered or when it is first listed as a parent of some
other commit, whichever comes first. The ordering token is a string
of variable length. Parents that don't already have an ordering
token are assigned one by appending to the child's token; the first
parent gets a "0" on the end, the second "1" and so on. As an
optimization, the "0" isn't appended if the child only has one parent.
When inserting a new commit into an element of rowidlist, it is
inserted in the position which makes the ordering tokens increase
from left to right.
This also simplifies the layout code by getting rid of the rowoffsets
variable, and terminates lines with an arrow after 5 rows if the line
would be longer than about 110 rows (rather than letting them go on
and terminating them later with an arrow if the graph gets too wide).
The effect of having the total ordering, and terminating the lines
early, is that it will be possible to lay out only a part of the graph
rather than having to do the whole thing top to bottom.

This reworks the way that the "Find" button (and the /, ?, ^F, and ^G

Now the searching is done in chunks using the scheduler, so the UI

The highlighting of matches using a yellow background is now done in

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).

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.

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.

This is a small extension to the code that reads the complete commit

This adds a feature to the diff display window where it will show

(is an ancestor of). Specifically, it will show the tags for all
tagged descendents that are not a descendent of another tagged
descendent of this commit, and the tags for all tagged ancestors
that are not ancestors of another tagged ancestor of this commit.
To do this, gitk reads the complete commit graph using git rev-list
and performs a couple of traversals of the tree. This is done in
the background, but since it can be time-consuming, there is an option
to turn it off in the `edit preferences' window.

The list of arguments to git-rev-list, including arguments that
select the range of commits, is now a part of the view specification.
If any arguments are given to gitk, they become part of the

for any new views created.
Getting an error from git-rev-list is no longer fatal; instead the

The conversion of the file list to use a text widget assumed incorrectly
that the list of files from git-diff-tree -r would correspond 1-1 with
the diff sections in the output of git-diff-tree -r -p -C, which is
not true when renames are detected. This fixes it by keeping the
elements in the difffilestart list in the order they appear in the
file list window.
Since this means that the elements of difffilestart are no longer
necessarily in ascending order, it's somewhat hard to do the dynamic
highlighting in the file list as the diff window is scrolled, so I

This bug was reported by Yann Dirson, and results in an 'Error:
expected boolean value but got ""' dialog when scrolling to the bottom
of the graph under some circumstances. The issue is that git-rev-list
isn't outputting all the boundary commits when it is asked for commits
affecting only certain files. We already cope with that by adding the
missing boundary commits in addextraid, but there we weren't adding a
0 to the end of the commitlisted list when we added the extra id to
the end of the displayorder list.
This fixes it by appending 0 to commitlisted in addextraid, thus keeping
commitlisted and displayorder in sync.

Previously, if we switched away from a view before we had finished
reading the git-rev-list output for it and laying out the graph, we
would discard the partially-laid-out graph and reread it from
scratch if we switched back to the view. With this, we preserve the
state of the partially-laid-out graph in viewdata($view) and restore
it if we switch back. The pipe to git-rev-list remains open but we
just don't read from it any more until we switch back to that view.
This also makes linesegends a list rather than an array, which turns
out to be slightly faster, as well as being easier to save and restore.

For a keyboard addict like me some keys are still missing from

like just after startup. While we're at it, complete the bindings for
moving the view seperately from the selected line. Currently, the up

on the commits viewed.
The idea is to have to normal keys change the selected line:
- Home selects first commit
- End selects last commit
- Up selects previous commit
- Down selects next commit
- PageUp moves selected line one page up
- PageDown moves selected line one page down
...and together with the Control key, it moves the commits view:
- Control-Home views first page of commits
- Control-End views last page of commits
- Control-Up moves commit view one line up
- Control-Down moves commit view one line down
- Control-PageUp moves commit view one page up

With this, gitk can know about the graphs for multiple sets of files
and directories of interest. Each set of files/dirs and its graph is
called a "view". There is always the "All files" view, which is the
complete graph showing all commits. If files or dirs are specified
on the command line, a "Command line" view is automatically created.
Users can create new views and switch between them, and can delete
any view except the "All files" view.
This required a bit of reengineering. In particular, some more things
that were arrays have now become lists. The idrowranges array is still
used while the graph is being laid out, but for rows that have been laid
out we use the rowrangelist list instead. The cornercrossings and
crossings arrays no longer exist, and instead we compute the crossings
when needed (in assigncolor).
Still to be done: make the back/forward buttons switch views as necessary;
make the updatecommits function work right; preserve the selection if
possible when the new view has to be read in; fix the case when the user
switches away from the current view while we are still reading it in
