This unifies findmore and findmorerev, and adds the ability to do
a search with or without wrap around from the end of the list of

Shift-up and shift-down are back by popular request, and the searches
they do don't wrap around. The other keys that do searches (/, ?,

First, paths ending in a slash were not matching anything. This fixes
path_filter to handle paths ending in a slash (such entries have to
match a directory, and can't match a file, e.g., foo/bar/ can't match
a plain file called foo/bar).
Secondly, clicking in the file list pane (bottom right) was broken
because $treediffs($ids) contained all the files modified by the

paths.
Secondly, this implements the path limiting for merge diffs as well
as the normal 2-way diffs.

When the user has specified a list of paths, either on the command line
or when creating a view, gitk currently displays the diffs for all files
that a commit has modified, not just the ones that match the path list.
This is different from other git commands such as git log. This change
makes gitk behave the same as these other git commands by default, that
is, gitk only displays the diffs for files that match the path list.
There is now a checkbox labelled "Limit diffs to listed paths" in the
Edit/Preferences pane. If that is unchecked, gitk will display the
diffs for all files as before.
When gitk is run with the --merge flag, it will get the list of unmerged
files at startup, intersect that with the paths listed on the command line
(if any), and use that as the list of paths.

This fixes the error reported by Michele Ballabio, where gitk will
throw a Tcl error "can't unset prevlines(...)" when displaying a
commit that has a parent commit listed more than once, and the commit
is the first child of that parent.
The problem was basically that we had two variables, prevlines and
lineends, and were relying on the invariant that prevlines($id) was
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.

A file copy would be detected only if the original file was modified in the
same commit. This implies that there will be a patch listed under the
original file name, and we would expect that clicking the original file
name in the file list warps the patch window to that file's patch. (If the
original file was not modified, the copy would not be detected in the first
place, the copied file would be listed as "new file", and this whole matter
would not apply.)
However, if the name of the copy is sorted after the original file's patch,
then the logic introduced by commit d1cb298b0b (which picks up the link
information from the "copy from" line) would overwrite the link
information that is already present for the original file name, which was
parsed earlier. Hence, this patch reverts part of said commit.

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),

This replaces the use of $mainfont, $textfont and $uifont with named

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

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 changes layoutrows and optimize_rows to make it possible to lay

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).

Secondly, there was a problem where the cursor wouldn't always turn

overlap slightly. This fixes that by using a counter rather than
always reverting to a counter when we leave the region of a link

Instead make the rowranges procedure compute its result by looking

The way gitk used to draw the lines joining a commit to the lines

when the line to the parent had a corner that coincided with a corner
on another line.

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
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).

We were doing two execs for each tag - one to map the tag ID to a

This speeds up the process by not reading the contents of the tag

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

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

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

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.

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.

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.

For a keyboard addict like me some keys are still missing from
gitk. Especially a key to select a commit when no commit is selected,
like just after startup. While we're at it, complete the bindings for
moving the view seperately from the selected line. Currently, the up
and down keys act on the selected line while pageup and pagedown act
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
- Control-PageDown moves commit view one page down

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
and laying it out; further optimizations.

The point where the line for a parent joins to the first child
shown is visually different from the lines to the other children,
because the line doesn't branch, but terminates at the child.

Now we don't parse the commits as we are reading them, we just put

The change in 8b7e5d76e8, which makes

right-click menu functions.
Yann Dirson pointed this out and had a patch that fixed the diff
menu functions by passing a "singlecommit" flag around. This fixes
it a bit differently, by making the ids and diffids variables be
either a single id, in the case of showing what a commit did, or
{oldid newid}, in the case of the diff menu functions. That way
we can just pass $ids to git-diff-tree as is. Most of the changes
in fact are just reversing the order of ids in $ids and $diffids,
because they used to be {child parent}, but git-diff-tree requires
old id before new id.

- don't do the $canv delete lines.$id in drawlines when drawing the

To generate the diff for a commit, gitk used to do
git-diff-tree -p -C $p $id
(and same thing to generate filenames, except using just "-r" there) which
does actually generate the diff from the parent to the $id, exactly like
it meant to do.
However, that really sucks with --dense, where the "parent" information
has all been rewritten to point to the previous commit. The diff actually
works exactly right, but now it's the diff of the _whole_ sequence of
commits all the way to the previous commit that last changed the file(s)
that we are looking at.
And that's really not what we want 99.9% of the time, even if it may be
perfectly sensible. Not only will the diff not actually match the commit
message, but it will usually be _huge_, and all of it will be totally
uninteresting to us, since we were only interested in a particular set of
files.
It also doesn't match what we do when we write the patch to a file.
So this makes gitk just show the diff of _that_ commit.
We might even want to have some way to limit the diff to only the
filenames we're interested in, but it's often nice to see what else
changed at the same time, so that's secondary.
The merge diff handling is left alone, although I think that should also
be changed to only look at what that _particular_ merge did, not what it
did when compared to the faked-out parents.

This just displays the result of git-cat-file on the tag in the
details pane. If the tag is a "direct" tag (the tag file contains
the SHA1 ID of a commit rather than a tag), we show the tag name
and SHA1 ID.
These are features requested by Junio. Any plain file under .git/refs
whose contents start with 40 hex characters is taken as a reference
and displayed like a head but with a light blue background (unless it
is in .git/refs/tags or .git/refs/heads, in which case it is displayed
as before). There is now a "Reread references" menu item in the File
menu which re-reads all the plain files under .git/refs and redisplays
any references that have changed.
With --parents, git-rev-list gives us the list of parents on the
first line of each commit. We use that rather than looking for
the parent: lines in the commit body, since this way we get to
know about the grafts for free.
When the graph gets too wide (as defined by the maxwidth variable,
which can be set in ~/.gitk), we can now terminate graph lines with
an arrow pointing downwards, and reintroduce them later with an
arrow pointing upwards when we need them. This makes the graph much
less cluttered on large repositories such as the linux kernel.
Unfortunately this has made it slower; it takes about 10 seconds
user time on the linux-2.6 repository on my machine now, compared
to 6 seconds before. I'll have to work on optimizing that. Also
on the todo list are making the arrow heads active (so if you click
on them you jump to the other end) and improving the placement of
the null entry.
The previous commit improved performance a lot but also meant that
we waited longer to see something drawn. This refines the heuristics
for when to call update so that (1) when we have finished processing
a bufferfull of information from git-rev-list, we call update if
enough time has elapsed, regardless of how many commits we've drawn,
and (2) the number of commits drawn between updates scales with the
total number of commits drawn: 1 for 1-99 commits, 10 for 100-9999
commits, or 100 for >= 10000 commits.
On a large repository with > 60,000 commits, each call to the Tk
update primitive (which gives Tk a chance to respond to events and
redraw the screen) was taking up to 0.2 seconds. Because the logic
was to call update after drawing a commit if 0.1 seconds had passed
since the last update call, we were calling it for every commit,
which was slowing us down enormously. Now we also require that we
have drawn 100 commits since the last update (as well as it being
at least 0.1 seconds since the last update). Drawing 100 commits
takes around 0.1 - 0.2 seconds (even in this large repo) on my G5.
This adds "Child: " lines to the commit window, which tells what children
a commit has.
It also cleans things up: it marks the text widget as no-wrap, which means
that it doesn't need to truncate the commit description arbitrarily by
hand. Also, the description itself is now done by a common helper routine
that handles both the parent and the children.

Now the history remembers when we have clicked on a graph line
and when we have asked for a diff between two commits, as well
as when we have displayed a commit.
The display when you click on a graph line now uses clickable
SHA1 IDs instead of the embedded "Go" buttons. Also made the

This adds a useful "Parent:" line to the git commit information window.

The effect of this is that it allows Tcl to do the locale-specific
conversion of the input data to its internal unicode representation.
That means that commit messages in Russian or other languages should
be displayed correctly now (according to the locale that is in effect.)
This is based on suggestions by Jeff Epler and Linus Torvalds, but
extended so that we do the switching between the watch cursor and
the normal cursor correctly as well.
Also fixed a bug pointed out by Junio Hamano - I wasn't incrementing
the link number (duh!).
When we display the commit message in the details pane, any string
of 40 [0-9a-f] characters that corresponds to a SHA1 ID that we
know about gets turned into a clickable link, and displayed in
blue and underlined.
We now keep a history of commits that we have looked at, and we
have forward and back buttons for moving within the history list.
If the graph gets to use more than a certain percentage (default 50%)
of the width of the top-left pane, we now reduce the amount of space
allowed for each graph line. This means it doesn't look quite as
nice but you can still see the headline for the commit. (Currently
the only way to customize the percentage is to edit your ~/.gitk
file manually.)
Specifically this should fix the following errors:
wrong # args: should be "startdiff ids" (fix from Junio Hamano)
can't read "filelines(....)": no such element in array
can't unset "treepending": no such variable
Now we see if the result is quite similar to one of the parents, and
if it is, display the result as a diff from that parent. If the result
is similar to more than one parent, pick the one that it's most
similar to.
Some places assumed .git is the GIT_DIR, resulting heads and
tags not showing when it was run like "GIT_DIR=. gitk --all".
This is not a contrived example --- I rely on it to verify
my private copy of git.git repository before pushing it out.

Stuff that ended up in the result is shown in bold with a "+" at the
beginning of the line; stuff that didn't is in the normal font with
a "-" at the beginning of the line. The color shows which parent
the stuff was in; red for the first parent, blue for the second, then
green, purple, brown, and the rest are grey. If the result is different
from all of the parents it is shown in black (and bold).
If there is a GCA for the parents of the merge, then a file is
interesting if some parent has a version that is different from both
the child and the GCA. If there is no GCA (e.g. for a merge that
pulls in an external project) then a file is interesting if the child's
version is different from all of the parents.
Next step is to actually show the differences for the interesting
files...
We display the files where the child differs from the first parent
first in black in the file list window, followed by the second parent
in blue, and so on using different colors for each parent (provided
you don't have more than 6 parents; if you do we cycle around).
We now kick off a single git-diff-tree -r --stdin and feed it all
the commit pairs we want to know about, instead of doing a separate
git-diff-tree invocation for each.
"Files" matches the find string against each of the files modified
by each commit, and can do exact, case-ignoring or regexp matching.
"Pickaxe" uses git-diff-tree -S'string' and can only do exact
matching. I called it "pickaxe" rather than "find within patch"
since it only finds commits where the string is present in the child
but not the parents or vice versa, and "pickaxe" is what the author
of that feature calls it.
This just invokes git-diff-tree. Also changed the readonly entry
widgets in the "write patch" and "generate tag" windows to have
flat relief, so it doesn't look like you should be able to modify
what's in them.
If we have a very long commit message, and we end up getting a
bufferfull of data from git-rev-list that all belongs to one commit,
we ended up throwing away the data from a previous read that should
have been included. The result was a error message about not being
able to parse the output of git-rev-list.
Also, if the git-rev-list output that we can't parse is long, only put
the first 80 chars in the error message. Otherwise we end up with an
enormous error window.
Check that $GIT_DIR (or .git, if GIT_DIR is not set) is a directory.
This means we can give a more informative error message if the user
runs gitk somewhere that isn't a git repository.
Right-click on a context row now brings up a menu allowing the user to
generate a diff between that row and the selected row. Left-click on
a graph line shows the parent and children connected by the line in
the details pane. Left-click on a circle in the graph selects that
commit. Left-click elsewhere in the graph does nothing.
When displaying a diff, the bottom-right file list box behaves
slightly differently now; instead of eliding all other files' diffs,
it now just scrolls the details pane so that the selected file's diff
starts at the top of the pane.
Since the diffs can be rather large, arrange for an update to be done
every 100ms while reading diffs.
Also removed the CVS revision keywords and bumped the version number
to 1.2.
With --header, git-rev-list gives us the contents of the commit
in-line, so we don't need to exec a git-cat-file to get it, and we
don't need the readobj command either.
Also fixed a residual problem with handling the commit that
has a parent listed twice.
This happens in the linux-2.6 tree. We draw the graph line
double-thick to show that this happened.
