gitk: Fix changing colors through Edit->Preferences
With tcl/tk8.5 the lset command seems to behave differently. When
changing the background color through Edit->Preferences, the changes
are applied, but new dialogs, such as View->New view... barf with
Error: unknown color name "{#ffffff}"
Additionally when closing gitk, and starting it up again, a bad value
has been saved to ~/.gitk, preventing gitk from running properly; it
fails with
Error in startup script: unknown color name "{#ffffff}"
...
This commit fixes the problem by changing the color dialogs to pass
the empty string {} as the list index to choosecolor. This causes
the lset and lindex commands used by choosecolor to use and set the
whole variable (bgcolor, fgcolor or selectbgcolor) rather than
treating them as a 1-element list. Tested with tcl/tk8.4 and 8.5.

gitk: Default to using po2msg.sh if msgfmt doesn't grok --tcl, -l and -d
This is a similar change to that submitted by Junio C Hamano for
git-gui. It tests whether the msgfmt command can be run successfully
with --tcl, -l and -d, and if not, falls back to using po/po2msg.sh.
Michele Ballabio <barra_cuda@katamail.com> pointed out that gitk
sometimes throws a Tcl error (can't read "yscreen") when switching
views, and proposed a patch. This is a different way of fixing it
which is a bit neater. Basically, in showview we only set yscreen if
the selected commit is on screen to start with, and then we only
scroll the canvas to bring it onscreen if yscreen is set and the
same commit exists in the new view.

[PATCH] gitk: Add horizontal scrollbar to the diff view
Adding horizontal scroll bar makes the scrolling feature more
discoverable to the users. The horizontal scrollbar is a bit narrower
than vertical ones so we don't make too big impact on available screen
real estate. The text and scrollbar widget layout is done using grid
geometry manager.
An interesting side effect of Tk scrollbars is that the "elevator"
size changes depending on the visible content. So the horizontal
scrollbar "elevator" changes as the user scrolls the view up and down.

[PATCH] Add an --argscmd flag to get the list of refs to show
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.

[PATCH] gitk: Add checkbutton to ignore space changes
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.

gitk: Use the UI font for the diff/old version/new version radio buttons
This makes the radio buttons for selecting whether to see the full diff,
the old version or the new version use the same font as the other user
interface elements.
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
commits to the beginning (or vice versa for reverse searches).
findnext and findprev are gone, and the buttons and keys for searching
all call dofind now. dofind doesn't unmark the matches to start with.
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 (/, ?,
return, M-f) do wrapping searches except for M-g.
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
commit, not just those within the file list. This fixes that too.
gitk: Fix some bugs with path limiting in the diff display
First, we weren't putting "--" between the ids and the paths in the
git diff-tree/diff-index/diff-files command, so if there was a tag
and a file with the same name, we could get an ambiguity in the
command. This puts the "--" in to make it clear that the paths are
paths.
Secondly, this implements the path limiting for merge diffs as well
as the normal 2-way diffs.
gitk: Integrate the reset progress bar in the main frame
This makes the reset function use a progress bar in the same location
as the progress bars for reading in commits and for finding commits,
instead of a progress bar in a separate detached window. The progress
bar for resetting is red.
This also puts "Resetting" in the status window while the reset is in
progress. The setting of the status window is done through an
extension of the interface used for setting the watch cursor.
gitk: Ensure tabstop setting gets restored by Cancel button
We weren't restoring the tabstop setting if the user pressed the
Cancel button in the Edit/Preferences window. Also improved the
label for the checkbox (made it "Tab spacing" rather than the laconic
"tabstop") and moved it above the "Display nearby tags" checkbox.
gitk: Limit diff display to listed paths by default
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.
gitk: Avoid an error when cherry-picking if HEAD has moved on
This fixes an error reported by Adam Piątyszek: if the current HEAD
is not in the graph that gitk knows about when we do a cherry-pick
using gitk, then gitk hits an error when trying to update its
internal representation of the topology. This avoids the error by
not doing that update if the HEAD before the cherry-pick was a
commit that gitk doesn't know about.
gitk: Check that we are running on at least Tcl/Tk 8.4
This checks that we have Tcl/Tk 8.4 or later, and puts up an error
message in a window and quits if not.
This was prompted by a patch submitted by Steffen Prohaska, but is
done a bit differently (this uses package require rather than
looking at [info tclversion], and uses show_error to display the
error rather than printing it to stderr).
gitk: Do not pick up file names of "copy from" lines
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.

The logic in stopfinding assumes that findcurline will be set if

setting findcurline. This makes sure we only set find_dirn in those
places if findcurline is already set.
The only thing that could be specified with diffopts was the number
of lines of context, but there is already a spinbox for that. So
this gets rid of it.
gitk: Fix bug where the last few commits would sometimes not be visible
We weren't calling showstuff for the last few commits under some
circumstances, causing the scrolling region not to be extended right
to the end of the graph. This fixes it.
This adds buttons to the edit preferences window to allow the user to
choose the main font, the text font (used for the diff display window)
and the UI font. Pressing those buttons pops up a font chooser window
that lets the user pick the font family, size, weight (bold/normal)
and slant (roman/italic).
gitk: Keep track of font attributes ourselves instead of using font actual
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.
gitk: Use named fonts instead of the font specification
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
that are using that font.
gitk: Fix the tab setting in the diff display window
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.
gitk: Add progress bars for reading in stuff and for finding
This uses the space formerly occupied by the find string entry field
to make a status label (unused for now) and a canvas to display a
couple of progress bars. The bar for reading in commits is a short
green bar that oscillates back and forth as commits come in. The
bar for showing the progress of a Find operation is yellow and advances
from left to right.
This also arranges to stop a Find operation if the user selects another
commit or pops up a context menu, and fixes the "highlight this" popup
menu items in the file list window.
insertrow and removerow were trying to adjust rowidlist, rowisopt
and rowfinal even if the row where we're inserting/deleting stuff
hasn't been laid out yet, which resulted in Tcl errors. This fixes
that.
Also we weren't deleting the link$linknum tag in appendwithlinks,
which resulted in SHA1 IDs in the body of a commit message sometimes
getting shown in blue with underlining when they shouldn't.
gitk: Simplify highlighting interface and combine with Find function
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.
Commit 8f4893639129acfc866c71583317090aa2a46eab changed mkpatchgo
to use diffcmd rather than constructing the diff command itself.
Unfortunately diffcmd returns the command with a "|" as the first
element (ready for use with open), but exec won't accept the "|".
Thus we need to remove the "|".
gitk: Get rid of lookingforhead, use commitinterest instead
Now that we have a general-purpose way of taking some action when a
commit ID of interest is encountered, use that for triggering the
git diff-index process when we find the currently checked-out head,
rather than the special-purpose lookingforhead variable.
Also do the commitinterest processing in getcommitlines rather than
in showstuff.
We weren't updating the rowfinal list in insertrow and removerow, so
it was getting out of sync with rowidlist, which resulted in Tcl errors.
This also optimizes the setting of rowfinal in layoutrows a bit.
gitk: Make it possible to lay out all the rows we have received so far
This arranges things so that we can do the layout all the way up to
the last commit that we have received from git log. If we get more
commits we re-lay and redisplay (if necessary) the visible rows.
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.
gitk: Fix bug causing undefined variable error when cherry-picking
When "Show nearby tags" is turned off and the user did a cherry-pick,

This makes sure we don't do that. Reported by Johannes Sixt.

This makes sure we don't do that. Reported by Johannes Sixt.
gitk: Do only the parts of the layout that are needed
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.
Instead, when looking for lines that should be terminated with a down
arrow, we look at the parents of the commit $downarrowlen + 1 rows
before. This gets rid of one more place where we are assuming that
all the rows are laid out in order from top to bottom.
gitk: Fix some problems with the display of ids as links
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
to work out which parent ids are appearing for the first time or need
an up arrow, instead of using idinlist. To detect the situation where
git log doesn't give us all the commits it references, this adds an
idpending array that is updated and used by getcommitlines.
This also fixes a bug where we weren't resetting the ordertok array when
updating the list of commits; this fixes that too, and a bug where we
could try to access an undefined element of commitrow if the user did
an update before gitk had finished reading in the graph.
Instead make the rowranges procedure compute its result by looking
in the rowidlist entries for the rows around the children of the id
and the id itself. This turns out not to take too long, and not having
to maintain idrowranges and rowrangelist speeds up the layout.
This also makes optimize_rows not use rowranges, since all it really
needed was a way to work out if one id is the first child of another,
so it can just look at the children list.
gitk: Add a window to list branches, tags and other references
This adds an entry to the File menu labelled "List references" which
pops up a window showing a sorted list of branches, tags, and other
references, with a little icon beside each to indicate what sort it
is. The list only shows refs that point to a commit that is included
in the graph, and if you click on a ref, the corresponding commit
is selected in the main window. The list of refs gets updated
dynamically.

If "Show nearby tags" is turned off, selecting "Update" from the File

getallcommits had been called previously. This also restructures
{re,}getallcommits to be a bit simpler.
In fixing the "can't unset idinlist" error, I moved the setting of
idinlist into the loop that splits the parents into "new" parents
(i.e. those of which this is the first child) and "old" parents.
Unfortunately this is incorrect in the case where we hit the break
statement a few lines further down, since when we come back in,
we'll see idinlist($p) set for some parents that aren't in the list.
This fixes it by moving the loop that sets up newolds and oldolds
further down.

gitk: Fix bug causing the "can't unset idinlist(...)" error
Under some circumstances, having duplicate parents in a commit could

Thanks to Jeff King for coming up with a test script to generate a

This changes the optimizer to insert pads to straighten downward
pointing arrows so they point straight down. When drawing the parent
link to the first child in drawlineseg, this draws it with 3 segments

on diagonal segments. This also fixes a couple of other minor bugs.

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.
gitk: Establish and use global left-to-right ordering for commits
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.
At the moment this just has two entries, which allow you to add the file
that you clicked on to the list of filenames to highlight, or replace
the list with the file.
This fixes the problem reported by Brian Downing where searching for
a string that doesn't exist would give a Tcl error. The basic problem
was that we weren't reading the data for the last commit since it
wasn't terminated with a null. This effectively adds a null on the end
(if there isn't one already) to make sure we process the last commit.
This also makes the yellow background behind instances of the search
string appear more consistently, and fixes a bug where the "/" key
would just find the same commit again and again instead of advancing.
gitk: Wait for the window to become visible after creating it
When the git log process returned an error immediately, we were
sometimes getting no main window and no error window displayed,
with the gitk process just hanging waiting for something. It appears
that the tkwait in show_error, which waits for the error window to
be destroyed, wasn't sufficient to allow the main window or the error
window to be mapped.
This adds a wait in the main startup code after the main window
has been created to wait until it is visible. This seems to fix the
problem.
[PATCH] gitk: Bind keyboard actions to the command key on Mac OS
git-gui already uses the command key for accelerators, but gitk has
never done so. I'm actually finding it very hard to move back and
forth between the two applications as git-gui is following the Mac
OS X conventions and gitk is not.
This trick is the same one that git-gui uses to determine which
key to bind actions to.

Cygwin's Tcl is configured to honor any occurence of ctrl-z as an
end-of-file marker, while some commits in the git repository and possibly
elsewhere include that character in the commit comment. This causes gitk
ignore commit history following such a comment and incorrect graphs. This
change affects only Windows as Tcl on other platforms already has
eofchar == {}. This fixes problems noted by me and by Ray Lehtiniemi, and
the fix was suggested by Shawn Pierce.

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).
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.
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.
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.
In commit 66e46f37de3ed3211a8ae0e8fc09c063bc3a1e08 I changed gitk to
store ids in rowrangelist and idrowranges rather than row numbers,
but I missed two places in the layouttail procedure. This resulted
in occasional errors such as the "can't read "commitrow(0,8572)":
no such element in array" error reported by Mark Levedahl. This fixes
it by using the id rather than the row number.
