8f48936391 gitk: Show changes in index and changes in working directory separately
This makes gitk show up to two fake commits when there are local changes
in the repository; one to represent the state of the index and one to
represent the state of the working directory.  The commit representing
the working directory is colored red as before; the commit representing
the index state is colored magenta (as being between red and blue in
some sense).

6ebedabf2d gitk: Fix bug introduced by previous commit
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.

cdaee5db16 gitk: Improve handling of -- and ambiguous arguments
This makes gitk more consistent with git rev-list and git log in its
handling of arguments that could be either a revision or a filename;
now gitk displays an error message and quits, rather than treating it
as a revision and getting an error in the underlying git log.  Now
gitk always passes "--" to git log even if no filenames are being
specified.

It also makes gitk display errors in invoking git log in a window
rather than on stderr, and makes gitk stop looking for a -d flag
when it sees a "--" argument.

c961b228bc gitk: Use git log and add support for --left-right
This is based on patches from Linus Torvalds and Junio Hamano, so the
ideas here are theirs.

This makes gitk use "git log -z --pretty=raw" instead of "git rev-list"
to generate the list of commits, and also makes it grok the "<" and ">"
markers that git log (and git rev-list) output with the --left-right
flag to indicate which side of a symmetric diff a commit is reachable
from.  Left-side commits are drawn with a triangle pointing leftwards
instead of a circle, and right-side commits are drawn with a triangle
pointing rightwards.  The commitlisted list is used to store the
left/right information as well as the information about whether each
commit is on the boundary.

4fb0fa197e gitk: Fix the find and highlight functions
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.

706d6c3e76 gitk: Add a progress bar to show progress while resetting
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.

9396cd385a gitk: Improve handling of whitespace and special chars in filenames
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).

62d3ea65a7 gitk: Speed up the reading of references
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.

219ea3a99b gitk: Show local uncommitted changes as a fake commit
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

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.

322a8cc9b3 gitk: New algorithm for drawing the graph lines
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.

avoid calling rowranges a second time inside drawlineseg (all its

7eb3cb9c68 gitk: Implement a simple scheduler for the compute-intensive stuff
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

0a4dd8b855 gitk: Don't try to list large numbers of tags or heads in the details pane
With some large repositories, a commit can end up on thousands of
branches, which results in an extremely long "Branches:" line in the

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).

e11f123315 gitk: New infrastructure for working out branches & previous/next tags
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.

9ca72f4f60 Make gitk save and restore window pane position on Linux and Cygwin.
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.

"wm geometry ." Under Linux, these two return different answers and the
latter one is correct.

e9937d2a03 [PATCH] Make gitk work reasonably well on Cygwin.
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.

3cd204e518 gitk: Fix enabling/disabling of menu items on Mac OS X
It seems that under Mac OS X, the menus get some extra entries (or
possibly fewer entries), leading to references to entries by an
absolute number being off.  This leads to an error when invoking
gitk --all under Mac OS X, because the "Edit view" and "Delete view"
entries aren't were gitk expects them, and so enabling them gives an
error.

This changes the code so it refers to menu entries by their content,
which should solve the problem.

67c22874cf [PATCH] gitk: Fix nextfile() and add prevfile()
The current nextfile() jumps to last hunk, but I think this is not
intention, probably, it's forgetting to add "break;". And this
patch also adds prevfile(), it jumps to previous hunk.

561d038ab8 gitk: Fix some bugs in the new cherry-picking code
When inserting the new commit row for the cherry-picked commit, we weren't
advancing the selected line (if there is one), and we weren't updating
commitlisted properly.

d1e46756d3 gitk: Improve responsiveness while reading and layout out the graph
This restructures layoutmore so that it can take a time limit and do
limited amounts of graph layout and graph optimization, and return 1
if it exceeded the time limit before finishing everything it could do.
Also getcommitlines reads at most half a megabyte each time, to limit
the time it spends parsing the commits to about a tenth of a second.

Also got rid of the unused ncmupdate variable while I was at it.
