gitk: Add a user preference to enable/disable use of themed widgets
Also move the hide-remotes option up into the commit display options
in the Edit->Preferences panel, since it affects the commit display
more than the diff display.
We only accepted either SHA1s or heads/tags that have been read. This
meant the user could not, e.g., enter HEAD to go back to the current
commit.
This adds code to call out to git rev-parse --verify if all other
methods of interpreting the string the user entered fail.
(git-rev-parse alone is not enough as we really want a single
revision.)
The error paths change slighly, because we now know from the rev-parse
invocation whether the expression was valid at all. The previous
"unknown" path is now only triggered if the revision does exist, but
is not in the current view display.

gitk: Fix direction of symmetric difference in optimized mode
ee66e08 (gitk: Make updates go faster, 2008-05-09) implemented an
optimized mode where gitk parses the arguments with rev-parse, and
manually reads history in chunks. As mentioned in the commit message,
symmetric differences are a problem there:
One wrinkle is that we have to turn symmetric diff arguments (of the
form a...b) back into symmetric diff form so that --left-right still
works, as git rev parse turns a...b into a b ^merge_base(a,b).
However, git-rev-parse returns a...b in the swapped order
b a ^merge_base(a,b)
This has been the case since at least 1f8115b (the state of master at
the time of the abovementioned ee66e08; Merge branch 'maint',
2008-05-08). So gitk flipped the sides of symmetric differences
whenever it was in optimized mode.
Fix this by swapping the sides of the reconstruction code.

gitk: Check git version before using --textconv flag
Commit 785b7535 ("gitk: use --textconv to generate diff text")
added the --textconv flag to the git diff commands used to
display commit diffs. Since some people use newer gitk with older
git installations, this adds a check on the git version to check
that it understands --textconv before using it.
For the most part gitk's focus is on showing history and changes in
a human readable form. For this reason, it makes sense to generate
the patch text in the diff view using --textconv so that textconv
drivers are used if they are defined.
gitk can also generate patches, but we do not use --textconv because
such patches could not be applied.

gitk: Fix compare-commits function when we have local changes
This fixes a bug in the compare-commits function added in commit 010509f2 ("gitk: Add a command to compare two strings of commits")
where gitk would show an error dialog if the comparison of commits
got to a fake commit (one showing local changes). It extends
getpatchid to handle these fake commits by using [diffcmd] to get
the git diff command variant to use, and also handles the situation
where an error occurs.
Now that we can have the fake commit IDs showing up, which are
00..00 and 00..01, the short ID is ambiguous. To make sure the links
point to the right commit, this adds a new [appendshortlink] procedure
which takes the full link destination, and uses that rather than
appendwithlinks.

gitk: Add a command to compare two strings of commits
This adds a row context menu command to compare this commit and its
descendants with the marked commit and its descendants. The results
are shown in the bottom-left pane. Commits are compared by checking
whether their headlines are the same and their patches have the same
patch ID as generated by git patch-id.
Merges are ignored and skipped over (as long as they have one
descendant). If two commits have the same patch ID then the process
will continue and compare their descendants, as long as they both have
exactly one descendant. If either commit has 0 or 2 or more descendants,
the comparison stops there. There is currently a limit of 100
comparisons.
This can be useful for checking whether one string of commits is just
a rebased version of another string of commits. Mark the end of one
string (i.e. the oldest commit in the string) and invoke "Compare with
marked commit" on the end of the other string.
As this is implemented, the UI will be unresponsive while the results
are being generated. This should be fixed.
gitk: Add a way to mark a commit, plus a "find descendant" command
This adds a context-menu command to put a mark on this commit. There
is at most one marked commit at any time, and it is indicated by a box
drawn around the headline. Once a commit is marked, two other
context-menu commands become available: one to select the marked commit,
and another to find the closest common descendant of this commit and
the marked commit.
The "find common descendant" command uses the displayed parent/child
relationships (i.e. the rewritten parent pointers produced by git log),
not the real parent/child relationships. Currently the UI will be
unresponsive while gitk is working out the nearest common descendant;
this should be improved in future.

There were actually two problems. This recipe created a situation where
git log would output a child commit after its parent. This meant that
we called fix_reversal which called splitvarc, which should call modify_arc
to note the fact that it has modified the arc that it has just split. It
wasn't, which meant that displayorder and other variables got into an
inconsistent state (a commit appearing twice in displayorder).
This then meant that the targetrow/targetid logic in drawvisible thought
it need to redraw each time. That, together with the fact that drawvisible
called drawcommits which called drawvisible if a redraw was needed, led
to the infinite loop.
In fact drawvisible is now the only caller of drawcommits. Thus, the
start and end row arguments to drawcommits always encompass the whole
visible area, so drawcommits doesn't need to call drawvisible to redraw;
it just needs to clear the screen and draw what it's been asked to.
This fixes these two problems by adding a call to modify_arc in
splitvarc and by taking out the call to drawvisible in drawcommits.
It also removes an unrelated left-over debugging puts in external_blame.

The "show origin of this line" function wasn't working when gitk was
run in a subdirectory, since it passed the path relative to the
top-level directory to git blame. This fixes it by passing the
absolute path to the file instead of the relative path.
The same problem occurs when running git gui blame, except that
git gui blame appears not to be able to accept an absolute path to the
file, so we make a relative path using a new [make_relative] function.
Finally, this fixes a bug in [show_line_source] where we weren't
setting id, resulting in an error when trying to find the origin of

gitk: Fix bug in accessing undefined "notflag" variable
As pointed out by Johannes Sixt and Alexander Gavrilov, commit 2958228430b63f2e38c55519d1f98d8d6d9e23f3 ("gitk: Fix switch statement
in parseviewargs") exposed a latent bug in that $notflag was never
initialized. Since it isn't used either, this removes it entirely.
gitk: Highlight only when search type is "containing:".
When the search type is "touching paths" or "adding/removing string",
it's not very useful to highlight instances of the search string in
the commit message, headline or author name, so this disables the
highlighting in those cases.
This was suggested by Mark Burton <markb@ordern.com>, but the
implementation is different to his patch, which tested $gdttype at
each place where $markingmatches was tested.
gitk: Restore scrolling position of diff pane on back/forward in history
This arranges to save the scrolling position of the diff display pane
when we move from displaying one thing to another, and then scroll the
pane to the same position when we go back to the previous thing using
the back or forward buttons. This works if we have clicked on a commit
and are in patch display mode, or if we have clicked on a line or a tag,
or have done a diff between two commits with the context menu. It
doesn't currently restore the pane to where it was if is was displaying
a commit in tree display mode.
For future extensibility, addtohistory now takes an extra optional
argument which is a script to invoke when moving from this thing to
another. The script needs to return a list of pairs of variable name
and value. If we go back to this thing, the godo procedure will set
the named variables to the values given. At present that is just used
to store the $ctext scrolling position, but in future we will use it
to store the state of which directories are open in the file list pane.
gitk: Fix context menu items for generating diffs when in tree mode
Currently, if you invoke the "diff this -> selected" or "diff selected
-> this" and gitk is in "Tree" mode rather than "Patch" mode, the
diff display pane will just show the header but not the actual diff,
unless gitk has done the diff before and thus has the list of files
that differ. This was because the logic in gettreediffline that
checked whether we had moved on to doing something else checked the
mode (Tree or Patch) before checking whether the ids we're diffing
had changed.
This fixes it. The new logic in gettreediffline is slightly hacky
and relies on the fact that the Tree/Patch mode only applies when
we're looking at a single commit, not at the diff between two commits.
A similar change was made as part of commit 76f15947af7, that added
bindings to all dialogs, and this duplication causes mkbrgo to be
called twice, the second time after the window has been destroyed.
As a result, an error window appears when the code tries to access
widgets.

gitk: Show local changes properly when we have a path limit
Since gitk looks for the HEAD commit to attach the fake commits for
local changes to, we can miss out on seeing the fake commits if we
have a path limit and the HEAD commit doesn't alter any of the files
in the path limit.
This fixes it by running
git rev-list -1 $head -- $paths
if we have a path limit, and taking the result of that as the commit
to attach the fake commits to. This means that we can be attaching
the fake commits to a different commit in each view, so we use a new
$viewmainhead($view) for that.
This also fixes a buglet where updatecommits would only fix up the
fake commits if the HEAD changed since the last call to updatecommits,
whereas it should fix them up if the HEAD has changed since this view
was last created or updated.
In Tcl, a comment in a switch command where a pattern would be expected
doesn't do what one would expect, so this moves the comments inside the
actions. Doing that shows up an extra "-" which this also removes.
gitk: Fix linehtag undefined error with file highlighting
Occasionally gitk will throw a Tcl error complaining that linehtag(n)
is undefined when. It happens when the commit list is still growing
(e.g. when updating the commit list) and gitk is set to highlight
commits that affect certain file(s). What happens is that the changes
to the commit list set need_redisplay to indicate that the display
needs to be redrawn. That causes the next call to drawcommits to call
clear_display, which unsets iddrawn and thus ensures that readfhighlight
won't call bolden on any rows that have moved. However, it is possible
for readfhighlight to be called after the commit list has changed but
before drawcommits has run, meaning that readfhighlight will potentially
think that rows have been drawn when they haven't, because of the
change in the id -> row mapping (and the fact that iddrawn is indexed
by id but line[hnd]tag are indexed by row number).
This fixes it (and also optimizes things a little) by making bolden
and bolden_name check need_redisplay before doing anything. If
need_redisplay is set, then there is no point doing anything because
the whole display is about to get cleared and redrawn, and it avoids
looking up line[hn]tag using stale row numbers.
This commit fixes two problems with commit encodings:
1) git-log actually uses i18n.logoutputencoding to generate
its output, and falls back to i18n.commitencoding only
when that option is not set. Thus, gitk should use its
value to read the results, if available.
2) The readcommit function did not process encodings at all.
This led to randomly appearing misconverted commits if
the commit encoding differed from the current locale.
Now commit messages should be displayed correctly, except
when logoutputencoding is set to an encoding that cannot
represent charecters in the message. For example, it is
impossible to convert Japanese characters from Shift-JIS
to CP-1251 (although the reverse conversion works).
The reason for using git log to read the commit and then getting
Tcl to convert its output is that is essentially what happens in
the normal path through getcommitlines, hence there is less chance
for unintended differences in how commits are processed in
getcommitlines and do_readcommit.

This adds to the regexps that are used to work out what sort of error

Transient windows are always kept above their parent, and don't occupy

This modifies gettreediffline so that it when we get both a "U" line
and an "M" line for the same file in the output from git diff-files
or git diff-index --cached (used when the user clicks on a fake commit)
we don't add the same filename to the treediff list twice.
This also makes getblobdiffline recognize the "* Unmerged path ..."
lines we get when we ask for the actual diffs, and makes a tiny
optimization in makediffhdr.
gitk: Make "show origin of this line" work on fake commits
This makes the "Show origin of this line" menu item work correctly
on the fake commits that gitk shows for local uncommitted changes.
With the fake commit for changes that aren't checked in to the index,
we can actually get a 3-way diff shown, which means we might have to
blame either the parent or the commit being merged in (which we get
from .git/MERGE_HEAD).
If the parent is the fake commit which shows the changes that have
been checked in to the index, then we need to get the SHA1 of the blob
for the version of the file that is in the index, then use git cat-file
blob to get the contents of the blob, and give that to git blame with --contents - so that git blame will do the blame on the index version
of the file. In that case, we might get the all-zeroes SHA1 back from
git blame, meaning that the line is new in the index version of the
file, so then we have to use $nullid2 (the pseudo-SHA1 of the fake
commit for the checked-in changes).
gitk: Unify handling of merge diffs with normal 2-way diffs
This adds code to getblobdiffline to make it able to recognize and
display merge diffs (i.e. N-way diffs for N >= 3) as well as normal
two-way diffs. This means that it can also correctly display the
3-way diff of the local changes when the git repository is in the
middle of a merge with conflicts.
This also removes getmergediffline and changes mergediff to invoke
getblobdiffline rather than getmergediffline.
gitk: Make the background color of marked lines configurable
This makes it possible for the user to configure the background color
of lines that are "marked". At the moment only the "show the origin
of this line" function marks lines. This also makes the user's choice
persistent by saving it in ~/.gitk.
gitk: Add a menu item to show where a given line comes from
This adds a menu item to the pop-up menu for the diff display window
which makes gitk find which commit added the line (via git blame)
and show that commit, with the line highlighted with a light-blue
background.
gitk: Fix some off-by-one errors in computing which line to blame
When walking back from the line where a right-click happened to the
previous hunk separator line to calculate the line number to work on,
we were counting every line including the one clicked on. That isn't
right; if the user clicked on the line immediately after the hunk
separator then the correct line number would be the one from the
hunk separator. Therefore this looks at the clicked-on line to work
out which parent to blame (or whether to blame the current commit),
and then looks only at the preceding lines to work out the offset from
the line number in the hunk separator.
This also fixes an off-by-one error when we are showing files rather
than diffs. In this case diff_menu_filebase is the line number of
the banner showing the file name, so the first line of the file is
at line $diff_menu_filebase + 1.
This also simplifies the code in find_hunk_blamespec a bit and arranges
that we don't pop up the context menu if the user clicks on a file
separator line or a hunk separator line.
gitk: Allow starting gui blame for a specific line
This adds a context menu item to the diff viewer pane that calls git
gui blame, focusing it on the clicked line. In case of combined
diffs, it also automatically deduces which parent is to be blamed.
Lines added by the diff are blamed on the current commit itself.
The context menu itself is added by this patch. It would be possible
to add the commands from the flist menu to it.

gitk: Fix file list context menu for merge commits
Currently it displays an ugly error box, because the treediffs array
is not filled for such commits. This fixes it by making
getmergediffline add the filenames it sees to the treediffs array
like gettreediffline does.

gitk: Allow forcing branch creation if it already exists
If gitk knows that the branch the user tries to create exists,
it should ask whether it should overwrite it. This way the user
can either decide to choose a new name, or move the head while
preserving the reflog.

This changes the link detection logic to accept strings of between 6
and 40 hex characters as a possible SHA1 ID of another commit, rather
than insisting on seeing the full 40 hex characters.
To make the logic that turns a possible link into an actual link work
with abbreviated IDs, this changes the way the commitinterest array is
used, and puts the code that deals with it in a pair of new functions.
The commitinterest array is now indexed by just the first 4 characters
of the interesting SHA1 ID, and each element is a list of id + command
pairs. This also pulls out the logic for expanding an abbreviated
SHA1 to the list of matching full IDs into its own function (the way
it is done is still the same slow way it was done before, which should
be improved some day).
This also fixes the bug where clicking on a link would take you to the
wrong commit if the line number of the target had changed since the
link was made.
This is based on a patch by Linus Torvalds, but totally rewritten by me.
This is the result of running make update-po and removing or fixing
the strings that were fuzzily matched. The ones that were fixed were
the ones where the only change was "git rev-list" to "git log", and
the "about gitk" message where the copyright year got updated.
To get xgettext to see the menu labels as needing translation, it
was necessary for arrange for them to be preceded by "mc". This
therefore changes makemenu to ignore the first element in each
menu item so that it can be "mc" in the makemenu call.
gitk: New way of constructing menus that allows for Alt+letter accelerators
This is inspired by patches from Robin Rosenberg but takes a different
approach. This adds a "makemenu" procedure for constructing menus
that allows the menu layout to be specified in a clear fashion, and
provides one place where the alt+letter accelerators can be detected
and handled.
The alt+letter accelerator is specified by putting an ampersand (&)
before the letter for the accelerator in the menu item name. (Two
ampersands in succession produce one ampersand in the menu item as
it appears on screen.) This is handled in makemenu.
We also add an mca procedure which is like mc but also does the
ampersand translation, for use when we want to refer to a menu item
by name. The mca name and the locations where we use it were
shamelessly stolen from Robin Rosenberg's patch.
This doesn't actually add any alt+letter accelerators yet.
gitk: Fix binding for <Return> in sha1 entry field
This adds a break so that gitk doesn't go and execute the global
binding for <Return> (i.e. find next) when the user presses the
return key in the sha1 entry field to indicate that gitk should
jump to the commit identified by what they just put into the
sha1 field.
gitk: Clean up file encoding code and add enable/disable option
This adds an option allowing the user to select whether gitk should
look up per-file encoding settings using git check-attr or not. If
not, gitk uses the global encoding set in the git config (as reported
by git config --get gui.encoding) for all files, or if that is not
set, then the system encoding.
The option is controlled by a checkbox in the Edit->Preferences
window, and defaults to off for now because git check-attr is so
slow. When the user turns it on we discard any cached diff file
lists in treediffs, because we may not have encodings cached for
the files listed in those lists, meaning that getblobdiffline will
do it for each file, which will be really really slow.
This adjusts the limit of how many paths cache_gitattr passes to each
instance of git check-attr depending on whether we're running under
windows or not. Passing only 30 doesn't effectively amortize the
startup costs of git check-attr, but it's all we can do under windows
because of the 32k limit on arguments to a command. Under other OSes
we pass up to 1000.
Similarly we adjust how many lines gettreediffline processes depending
on whether we are doing per-file encodings so that we don't run for
too long. When we are, 500 seems to be a reasonable limit, leading
to gettreediffline taking about 60-70ms under Linux (almost all of
which is in cache_gitattr, unfortunately). This means that we can
take out the update call in cache_gitattr.
This adds a simple cache on [tclencoding]. Now that we get repeated
calls to translate the same encoding, this is useful.
This reindents the new code added in the last couple of commits to
conform to the gitk 4-space indent and makes various other improvements:
use regexp in gitattr and cache_gitattr instead of split + join + regsub,
make gui_encoding be the value from [tclencoding] to avoid having to
do [tcl_encoding $gui_encoding] in each call to get_path_encoding,
and print a warning message at startup if $gui_encoding isn't
supported by Tcl.
gitk: Implement batch lookup and caching of encoding attrs
When the diff contains thousands of files, calling git-check-attr once
per file is very slow. With this patch gitk does attribute lookup in
batches of 30 files while reading the diff file list, which leads to a
very noticeable speedup.
It may be possible to reimplement this even more efficiently, if
git-check-attr is modified to support a --stdin-paths option.
Additionally, it should quote the ':' character in file paths, or
provide a more robust way of column separation.

This allows the encoding to be specified for file contents and used
when displaying files and diffs in the bottom-left pane. When
displaying diffs, the encoding for each diff hunk is that for the file
that the diff hunk is from, so it can change through the course of the
diff.
The encoding for file contents is determined as follows:
- File encoding defaults to the system encoding.
- It can be overridden by setting the gui.encoding option.
- Finally, the 'encoding' attribute is checked on
per-file basis; it has the last word.
Note: Since git-check-attr does not provide support for reading
attributes from trees, attribute lookup is done using files from the
working directory.
This also extends the range of supported encoding names, adding
ShiftJIS and Shift-JIS as aliases for Shift_JIS, and allowing
cp-*, cp_*, ibm-*, ibm_*, jis-* and jis_* as aliases for cp*,
ibm* and jis* respectively.
This also fixes some bugs in handling of non-ASCII filenames. Core
git apparently supports only locale-encoded filenames, so processing
is done using the system encoding.

An OSX user has reported that gitk's context menus are not usable
under OSX because it doesn't provide a way to generate <Button-3>

so use that for the context menus instead on OSX.

gitk: Allow safely calling nukefile from a run queue handler
Originally dorunq assumed that the queue entry remained first
in the queue after the script eval, and blindly removed it.
However, if the handler calls nukefile, it may not be the
case anymore, and a random queue entry gets dropped instead.
This makes dorunq remove the entry before calling the
script, and adds a global variable to allow other functions
to determine if they are called from within a dorunq handler.

This draws the currently checked-out head with a yellow circle, as
suggested by Linus Torvalds, and fixes various places in the code
where we assumed that the current head always had a branch. Now we
can display the fake commits for local changes on a detached head.
gitk: Fix bug introduced by "gitk: Fix "wrong # coordinates" error on reload"
Commit 94503a66c56c935e77a8fbe3622f1f56b7134ccc ("gitk: Fix "wrong #
coordinates" error on reload") was correct as far as it went, but
introduced a problem because it didn't also clear out boldrows and
boldnamerows in clear_display. This resulted in Tcl errors after
scrolling through the graph for a while if some rows were highlighted.
This fixes it.
gitk: Fix bug where current row number display stops working
The display of the current row number would stop working if the user
clicked on a line, or if selectedline got unset for any other reason,
because the trace on it got lost when it was unselected. This fixes
it by changing the places that unset selectedline to set it to the
empty string instead, and the places that tested for it being set or
unset to compare it with the empty string. Thus it never gets unset
now. This actually simplified the code in a few places since it can
be compared for equality with a row number now without first testing
if it is set.
This fixes the Tk error "wrong # coordinates: expected 0 or 4, got 2"
that sometimes occurred when reloading. The problem was that we didn't
unset the variables containing the canvas item id numbers for the
displayed rows when we cleared the canvases. Thus make_secsel would
think it had something to do when it didn't.
Thanks to Michele Ballabio for finding a way to trigger the bug
reliably.
Now that git checkout reports progress when checking out files, we
can use that to provide a progress bar in gitk. We re-use the green
progress bar (formerly used when reading stuff in) for that.
