2007-08-17[PATCH] gitk: Handle 'copy from' and 'copy to' in diff headers.Johannes Sixt
If a commit contained a copy operation, the file name was not correctly determined, and the corresponding part of the patch could not be navigated to from the list of files. Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-08-17gitk: Fix bug in fix for warning when removing a branchPaul Mackerras
My fix in commit b1054ac985aebc90c0a78202dab8477b74d7818a was only half-right, since it ignored the case where the descendent heads of the head being removed correspond to two or more different commits. This fixes it. Reported by Mark Levedahl. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-08-15[PATCH] gitk: Make the date/time display configurableArjen Laarhoven
The new 'datetimeformat' configuration variable in ~/.gitk can be set to a Tcl 'clock format' format string to modify the display of dates and times. http://www.tcl.tk/man/tcl8.4/TclCmd/clock.htm has a list of allowed fields.

2007-08-15[PATCH] gitk: Let user easily specify lines of context in diff viewSteffen Prohaska
More lines of context sometimes help to better understand a diff. This patch introduces a text field above the box displaying the blobdiffs. You can type in the number of lines of context that you wish to view. The number of lines of context is saved to ~/.gitk.

2007-08-15gitk: Fix warning when removing a branchPaul Mackerras
When we had two heads on the same commit, and the user tried to remove one of them, gitk was sometimes incorrectly saying that the commits on that branch weren't on any other branch. This fixes it. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-08-13gitk: Fix bug causing Tcl error when updating graphPaul Mackerras
If "Show nearby tags" is turned off, selecting "Update" from the File menu will cause a Tcl error. This fixes it. The problem was that we were calling regetallcommits unconditionally, but it assumed that getallcommits had been called previously. This also restructures {re,}getallcommits to be a bit simpler.

2007-08-13gitk: Fix bug introduced in commit 67a4f1a7Paul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>

2007-08-12[PATCH] gitk: Handle MouseWheel events on WindowsMark Levedahl
Windows, unlike X-Windows, sends mousewheel events by default to the window that has keyboard focus and uses the MouseWheel event to do so. The window to be scrolled must be able to take focus, but gitk's panels are disabled so cannot take focus. For all these reasons, a different design is needed to use the mousewheel on Windows. The approach here is to bind the mousewheel events to the top level window and redirect them based upon the current mouse position.

2007-08-12[PATCH] gitk: Enable selected patch text on WindowsMark Levedahl
On windows, mouse input follows the keyboard focus, so to allow selecting text from the patch canvas we must not shift focus back to the top level. This change has no negative impact on X, so we don't explicitly test for Win32 on this change. This provides similar selection capability as already available using X-Windows.

2007-08-12gitk: Fix bug causing the "can't unset idinlist(...)" errorPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-07-27gitk: Add a context menu for file list entriesPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-07-26gitk: Fix bugs in the Find functionPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-07-23gitk: Wait for the window to become visible after creating itPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-07-22[PATCH] gitk: Bind keyboard actions to the command key on Mac OSShawn O. Pearce
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. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-07-22[PATCH] gitk: Ignore ctrl-z as EOF on windowsMark Levedahl
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. Signed-off-by: Mark Levedahl <mdl123@verizon.net> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-07-22gitk: Make the fake commit for the index changes green rather than magentaPaul Mackerras
The magenta was a bit close in color to the normal blue commits. This makes them green instead as suggested by Linus. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-07-13gitk: Show changes in index and changes in working directory separatelyPaul Mackerras
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). Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-07-13gitk: Fix bug introduced by previous commitPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-07-12gitk: Improve handling of -- and ambiguous argumentsPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-07-09gitk: Use git log and add support for --left-rightPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-07-09gitk: Fix bug causing "can't read commitrow(0,n)" errorPaul Mackerras
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.

2007-07-09[PATCH] gitk: Fix for tree view ending in nested directoriesBrian Downing
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. Signed-off-by: Brian Downing <bdowning@lavos.net> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-07-04gitk: Remove the unused stopfindproc functionPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-07-04gitk: Fix bug in the anc_or_desc routinePaul Mackerras
I missed the case where both nodes have no children and therefore have no incoming arcs. This fixes it. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-07-04gitk: Fix the find and highlight functionsPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-06-28gitk: Update selection background colorbar in prefs dialogMark Levedahl
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. Signed-off-by: Mark Levedahl <mdl123@verizon.net>
2007-06-28gitk: Use a spinbox for setting tabstop settingsMark Levedahl
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. Signed-off-by: Mark Levedahl <mdl123@verizon.net>
2007-06-26gitk: Add a progress bar to show progress while resettingPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-06-23gitk: Improve handling of whitespace and special chars in filenamesPaul Mackerras
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).

2007-06-23gitk: Fix bug causing nearby tags/heads to sometimes not be displayedPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-06-23gitk: Limit how often we change the canvas scrolling regionPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-06-23gitk: Add a "reset branch to here" row context-menu operationPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-06-23gitk: Get rid of the childlist variablePaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-06-23gitk: Speed up the reading of referencesPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-06-23gitk: Show local uncommitted changes as a fake commitPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-06-23gitk: New algorithm for drawing the graph linesPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-06-23gitk: Store ids in rowrangelist and idrowranges rather than row numbersPaul Mackerras
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).

2007-06-23gitk: Disable the head context menu entries for the checked-out branchPaul Mackerras

2007-06-23gitk: Cope with commit messages with carriage-returns and initial blank linesPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-06-23gitk: Implement a simple scheduler for the compute-intensive stuffPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-06-23gitk: Improve the behaviour of the initial selectionPaul Mackerras

2007-06-23gitk: Don't try to list large numbers of tags or heads in the details panePaul Mackerras
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). Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-06-23gitk: New infrastructure for working out branches & previous/next tagsPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-05-22[PATCH] gitk: Allow specifying tabstop as other than default 8 characters.Mark Levedahl
Not all projects use the convention that one tabstop = 8 characters, and a common convention is to use one tabstop = one level of indent.
