[PATCH] gitk i18n: Recode gitk from latin1 to utf8 so that the (c) copyright character is valid utf8.
When using translations, the target language must be encoded in utf-8
because almost all target languages will contain non-ascii characters.
For that reason, the non-translated strings should be in utf-8 as well
so that there isn't any encoding mixup inside the program.
By setting the environment variable GITK_MSGSDIR, one can manually set
the directory where the .msg files are located. This is quite handy
during development with GITK_MSGSDIR=po.

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.
* Add/remove fake commits (for local changes) when updating the view

but there are now no local changes.
gitk: Fix more bugs resulting in Tcl "no such element in array" errors
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.
This also fixes a possible infinite recursion with rowofcommit and
update_arcrows calling each other ad infinitum.
First, if we invalidate the layout for all rows (i.e. from row 0 on),
we were calling undolayout with an empty string as the argument.
Second, the comparison in make_disporder that tests if we need to
call update_arcrows was the wrong way around.
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.
gitk: Fix bug in parsing multiple revision arguments
If the user specified multiple revisions arguments on the command
line or for a view, we were passing the whole list of arguments to
git rev-parse as a single argument, and thus git rev-parse didn't
interpret it as revisions. This fixes it by adding an eval so the
arguments get passed to git rev-parse as separate arguments.
We weren't setting vtokmod and varcmod in renumbervarc, so after a
call to renumbervarc we sometimes weren't reassigning row numbers to
all the arcs whose row numbers had changed. This fixes it.
This also collapses layoutmore and showstuff into one procedure and
gets rid of the phase variable.
gitk: Use git log without --topo-order and reorganize the commits ourselves
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.
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
find_dirn is, but findnext and findprev can set find_dirn without
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,
we were trying to access variables relating to the descendent/ancestor
tag & head computations in addnewchild though they hadn't been set.
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.

gitk: Fix bug causing Tcl error when updating graph
If "Show nearby tags" is turned off, selecting "Update" from the File

we were calling regetallcommits unconditionally, but it assumed that
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
trigger a "can't unset idinlist" Tcl error. This fixes the cause
(the logic in layoutrows could end up putting the same commit into
rowidlist twice) and also puts a catch around the unset to ignore
the error.
Thanks to Jeff King for coming up with a test script to generate a
repo that shows the problem.
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
like other parent links if it is only one row high with an arrow.
These two things mean we can dispense with the workarounds for arrows
on diagonal segments. This also fixes a couple of other minor bugs.
gitk: Improve the drawing of links to parent lines
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.
[PATCH] gitk: Fix for tree view ending in nested directories
Unroll the prefix stack when assigning treeheights when leaving
proc treeview. Previously, when the ls-tree output ended in
multiple nested directories (for instance in a repository with a
single file "foo/bar/baz"), $treeheight("foo/bar/") was assigned
twice, and $treeheight("foo/") was never assigned. This led to
an error when expanding the "foo" directory in the gitk treeview.

This was a hangover from before the "Files" and "Pickaxe" parts of
the Find function were moved to the highlight facility in commit 60f7a7dc4904ba4baab44b70e2675a01e6172f54. It serves no useful
purpose any more, so this removes it.
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.
gitk: Update selection background colorbar in prefs dialog
The callback function was incorrectly set to update the background
colorbar when updated the selection background. This did not affect the
colors chosen or their use, just their presentation in the preferences
dialog box.
The tabstop must be a smallish positive integer, and a spinbox is the
accepted UI control to accomplish this limiting rather than the text
entry box previously used.
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.
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).
gitk: Fix bug causing nearby tags/heads to sometimes not be displayed
When we compute descendent heads and descendent/ancestor tags, we
cache the results. We need to be careful to invalidate the cache
when we add stuff to the graph. Also make sure that when we cache
descendent heads for a node we only cache the heads that are actually
descendents of that node.
gitk: Limit how often we change the canvas scrolling region
For some unknown reason, changing the scrolling region on the canvases
provokes multiple milliseconds worth of computation in the X server,
and this can end up slowing gitk down significantly. This works around
the problem by limiting the rate at which we update the scrolling region
after the first 100 rows to at most 2 per second.
gitk: Add a "reset branch to here" row context-menu operation
This adds an entry to the menu that comes up when the user does a
right-click on a row. The new entry allows the user to reset the
currently checked-out head to the commit for the row that they did
the right-click on. The user has to select what type of reset to
do, and confirm the reset, via a dialog box that pops up.
The information in childlist is a duplicate of what's in the children
array, and it wasn't being accessed often enough to be really worth
keeping the list around as well.
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.
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
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.
