This allows gitk to be used to display a different set of refs each
the display is refreshed. This is useful when gitk is called from
other porcelain suites, for doing such things as displaying the set of
patches in a patch stack.
The user specifies a command as the argument to the --argscmd option.
The command is run initially and each time the display is refreshed,
and is expected to generate a list of commit IDs, one per line. Those
commits are appended to the commits passed on the command-line when
constructing the git log command to be executed.
The command is considered to be an attribute of a view, and has its
own field in the saved view, and an edit field in the view editor.

Since we limit the rate at which we do updates to the canvas scrolling
regions, it's possible to get into selectline for a row that is
outside the currently-set scrolling region. When this happens,
selectline can't scroll to show the selected line, and as a
consequence, drawvisible chooses some other bogus row to be the
target row.
This fixes it by calling setcanvscroll from selectline in this case.
We also set selectedline (and currentid) before calling drawvisible
so that drawvisible makes the right choice of target row.

First, insertfakerow and removefakerow weren't updating vrowmod,
and hence displayorder was not getting updated when it needed to,
in the case where the fake row was being inserted into or removed
from the last arc. The comparison of varctok vs vtokmod was moved
into modify_arc for these cases (and for the call in rewrite_commit)
to avoid duplicating the extra code needed. Second, the logic in
update_arcrows didn't end up truncating displayorder and unsetting
cached_commitrow if the first modified row was in the last arc.
This fixes these problems.

Previously we passed the arguments indicating what commits the user
wants to view through git rev-parse to get a list of IDs (positive and
negative), then gave that to git log. This had a couple of problems,
notably that --merge and --left-right didn't get handled properly.
Instead we now just pass the original arguments to git log. When doing
an update, we append --not followed by the list of commits we have seen
that have no children, since we have got (or will get) their ancestors
from the first git log. If the first git log isn't finished yet, we
might get some duplicates from the second git log, but that doesn't
cause any problem.

Occasionally the target row stuff would scroll the display to some
uninteresting commit while reading. There were two problems: one
was that drawvisible would set targetrow even if there was no target
previously and no row selected, and the other was that it was possible
for the target row to get pushed down past numcommits, if drawvisible
was called after rows were added but before layoutmore got run.
The first problem is fixed by just not setting targetrow/id unless
there is a selected row or they were set previously.
The second problem is fixed by updating numcommits immediately new
rows are added. This leads to a simplification of layoutmore and
chewcommits but also means that some of the things that were done in
layoutmore now need to be done elsewhere, since layoutmore can no
longer use numcommits to know how much it has seen previously.
Hence the changes to getcommits, initlayout and setcanvscroll.

When updating the graph, gitk uses a git log command with commit
limiting in order to get just the new commits. When path limiting
is also in effect, git log rewrites the parents of the commits it
outputs in order to represent just the subgraph that modifies the
listed paths, but it doesn't rewrite the parents on the boundary
of the graph. The result is that when updating, git log does not
give gitk the information about where the new commits join in to
the existing graph.
This solves the problem by explicitly rewriting boundary parents
when updating. If we are updating and are doing path limiting,
then when gitk finds an unlisted commit (one where git log puts a
"-" in front of the commit ID to indicate that it isn't actually
part of the graph), then gitk will execute:
git rev-list --first-parent --max-count=1 $id -- paths...
which returns the first ancestor that affects the listed paths.
(Currently gitk executes this synchronously; it could do it
asynchronously, which would be more complex but would avoid the
possibility of the UI freezing up if git rev-list takes a long time.)
Then, if the result is a commit that we know about, we rewrite the
parents of the children of the original commit to point to the new
commit. That is mostly a matter of adjusting the parents and children
arrays and calling fix_reversal to fix up the graph.

This fixes a bug in updating the graph after we have cherry-picked
a commit in gitk and then added some new stuff externally. First,
we weren't updating viewincl with the new head added by the cherry-
pick. Secondly, getcommitlines was doing bad things if it saw a
commit that was already in the graph (was already in an arc). This
fixes both things. If getcommitlines sees a commit that is already
in the graph, it ignores it unless it was not listed before and is
listed now. In that case it doesn't assign it a new arc now, and
doesn't re-add the commit to its arc.

Ignoring space changes can be helpful. For example, a commit
claims to only reformat source code and you quickly want to
verify if this claim is true. Or a commit accidentally changes
code formatting and you want to focus on the real changes.
In such cases a button to toggle of whitespace changes would be
quite handy. You could quickly toggle between seeing and
ignoring whitespace changes.
This commit adds such a checkbutton right above the diff view.
However, in general it is a good thing to see whitespace changes
and therefore the state of the checkbutton is not saved. For
example, space changes might happen unintentionally. But they are
real changes yielding different sha1s for the blobs involved.

The make_disporder function has an optimization where it assumed that
if displayorder was already long enough and the first entry in it for
a particular arc was non-null, then the whole arc was present. This
turns out not to be true in some circumstances, since we can add a
commit to an arc (which truncates displayorder to the previous end of
that arc), then call make_disporder for later arcs (which will pad
displayorder with null elements), then call make_disporder for the
first arc - which won't update the null elements.
This fixes it by changing the optimization to check the last element
for the arc instead of the first.

Since commits come in out of order and get sorted as we see them,
we can have commits coming in and being placed before the commits
that are visible in the graph display pane. Previously we just
displayed a certain range of row numbers, meaning that when
incoming commits were placed before the displayed range, the
displayed commits were displaced downwards. This makes it so
that we keep the same set of commits displayed, unless the user
explicitly scrolls the pane, in which case it scrolls as expected.
We do this by having a "target" commit which we try to keep in the
same visible position. If commits have come in before it we scroll
the canvases by the number of rows that it has moved in the display
order.
This also fixes a bug in rowofcommit where it would test
cached_commitrow before possibly calling update_arcrows, which is
where cached_commitrow gets invalidated if things have changed.

This restores date mode, which lists commits by date, as far as possible
given the constraint that parents come after all their children. To
implement this in the new framework, we (1) only join a new commit onto
an existing arc if the arc is the last arc created, (2) treat arcs as
seeds unless they have a child arc that comes later, and (3) never
decrease the token value for an arc.
This means we get lots of "seeds", which exposed some quadratic behaviour
in adding and removing seeds. To fix this, we add a vbackptr array, which
points to the arc whose vleftptr entry points to us, and a vlastins array,
which shows where in an arc's vdownptr/vleftptr list we last inserted a
parent, which acts as a hint of a good place to start looking for where to
insert a new child.
This also ensures the children array elements stay in sorted order at all
times. We weren't resorting the children lists when reassigning tokens
in renumbervarc. Since the children lists are now always sorted, we don't
have to search through all elements to find the one with the highest token;
we can just use the last element.

First, update_arcrows was being overly aggressive in trimming
displayorder, resulting in calls to rowofcommit sometimes trimming off
commits that layoutrows had asked for in make_disporder and was relying
on having present. This adds a vrowmod($view) variable that lets
update_arcrows be more precise in trimming off the invalid bits of
displayorder (and it also simplifies the check in make_disporder).
This modifies modify_arc and its callers so that vrowmod($view) is
updated appropriately.
Secondly, we were sometimes calling idcol with $i==-1, which resulted
in a call to ordertoken with the null string. This fixes it by
forcing $i to 0 if it is less than zero.

Instead of computing ordertok values and arc row numbers in
getcommitlines, this defers computing them until they are needed.
So getcommitlines no longer calls update_arcrows; instead it gets
called from rowofcommit and make_disporder. Things that modify arcs
now call modify_arc instead of setting vtokmod/varcmod directly,
and modify_arc does the undolayout that used to be in update_arcrows.
Also, idcol and make_idlist now use a new ordertoken function instead
of the ordertok variable. ordertoken uses ordertok as a cache, but
can itself compute the ordering tokens from scratch. This means that
the ordering tokens (and hence the layout of the graph) is once again
determined by the topological ordering we put on the graph, not on the
order in which we see the commits from git log, which improves the
appearance of the graph.

This very large patch implements code to organize the commits from
git log into "arcs" (sequences of commits where each pair of adjacent
commits are the only parent and child of each other), and orders the
arcs so as to get a topological ordering of the commits. This means
we can use git log without --topo-order and display the commits as we
get them, incrementally, which makes the cold-cache start up time much
faster, particularly on unpacked repos.
One beneficial effect of this is that the File->Update menu item now
just adds any new commits to the existing graph instead of rereading
the whole thing from scratch, which is much faster. (If you do want
to reread the whole graph from scratch you can use File->Reload.)
At an implementation level, this means that the displayorder and
parentlist lists are no longer fully valid at all times, and the
commitrow array has gone. New procedures commitinview and commitonrow
replace the commitrow array, and make_disporder ensures that
displayorder and parentlist are valid for a range of rows.
The overall time to load the kernel repository has gone up a bit, from
~9 seconds to ~11 seconds on my G5, but I think that is worth it given
that the time to get a window up with commits displayed in it has gone
from ~3 seconds to under 1 second.

throw a Tcl error "can't unset prevlines(...)" when displaying a

is the first child of that parent.
The problem was basically that we had two variables, prevlines and

set iff $id was in the lineends($r) list for some $r. But having
a duplicate parent breaks that invariant since we end up with the
parent listed twice in lineends.
This fixes it by simplifying the logic to use only a single variable,
lineend. It also rearranges things a little so that we don't try to
draw the line for the duplicated parent twice.

Unfortunately there seems to be a bug in Tk8.5 where font actual -size
sometimes gives the wrong answer (e.g. 12 for Bitstream Vera Sans 9),
even though the font is actually displayed at the right size. This
works around it by parsing and storing the family, size, weight and
slant of the mainfont, textfont and uifont explicitly.
Signed-off-by: Paul Mackerras <paulus@samba.org>
This replaces the use of $mainfont, $textfont and $uifont with named
fonts called mainfont, textfont and uifont. We also have variants
called mainfontbold and textfontbold. This makes it much easier to
make sure font size changes are reflected everywhere they should be,
since configuring a named font automatically changes all the widgets

Signed-off-by: Paul Mackerras <paulus@samba.org>
This fixes the bug where we were using the wrong font to calculate
the width of the tab stops in the diff display window.
If we're running on Tk 8.5 we also use the new -tabstyle wordprocessor
option that makes tabs work as expected, i.e. a tab moves the cursor
to the right until the next tab stop is reached. On Tk 8.5 we also
get fancy and set the first tab stop at column 1 for a normal diff
or column N for a merge diff with N parents.
On Tk8.4 we can't do that because the tabs work in the "tabular"
style, i.e. the nth tab character moves to the location of the nth
tab position, *unless* you ask for the default tab setting, which
gives 8-column tabs that work in the "wordprocessor" mode. So on
Tk8.4 if the tab setting is 8 we ask for default tabs. This means
that a tab setting of 7 or 9 can look quite different to 8 in some
cases.

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

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

so it can just look at the children list.

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).

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).

Neither the "check out this branch" nor the "remove this branch"
menu item can be used on the currently-checked out branch, so disable
them.

In some repositories imported from other systems we can get carriage
return characters in the commit message, which leads to a multi-line
headline being displayed in the summary window, which looks bad.
Also some commit messages start with one or more blank lines, which
leads to an empty headline. This fixes these problems.

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.

It used to be that if you clicked on a line while gitk was still drawing
stuff, it would immediately re-select the first line of the display.
This fixes that.

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
a common convention is to use one tabstop = one level of indent. For such
projects, using 8 characters per tabstop often shows too much whitespace
per indent. This allows the user to configure the number of characters
to use per tabstop.

Cygwin's tk by default uses a very dark selection background color that
makes the currently selected text almost unreadable. On linux, the default
selection background is a light gray which is very usable. This makes the
default a light gray everywhere but allows the user to configure the
color as well.

Made the default buttons on the dialog active and focused upon the
dialog appearence.
Bound 'Escape' and 'Return' keys to the dialog dismissal where it
was appropriate: mainly for dialogs with only one button and no
editable fields.
Unified the look of the "About gitk" and "Key bindings" dialogs.
