a4390ace1a gitk: Fix "git gui blame" invocation when called from top-level directory
When run in the top-level directory of a git repository, "git
rev-parse --git-dir" doesn't return an absolute path, but merely
".git", so the selected file for "git gui blame" has a relative path.
The function make_relative then tries to make the already relative
path relative, which results in a path like "../../../../Makefile"
with as many ".." as there are elements of [pwd].

This regression was introduced by commit 9712b81 (gitk: Fix bugs in
blaming code, 2008-12-06), which fixed "git gui blame" when called from
subdirs.

This also fixes it for bare repositories.

70a5fc443a gitk: Disable checkout of remote branches
At the command line, trying to check out a remote branch gives you a
detailed warning message, but the gitk GUI currently allows it without
any fuss.

Since the GUI is often used by people much less familiar with git, it
seems reasonable to make the GUI more restrictive than the command line,
not less.

This prevents a lot of detached HEAD commits by new users.

51a7e8b654 gitk: Improve appearance of radiobuttons and checkbuttons
Commit 5497f7a23a ("gitk: Add configuration
for UI colour scheme") added a call to tk_setPalette at startup.
Unfortunately, tk_setPalette always chooses a dark red color for
the selectColor value if none is given explicitly, and this makes
checkbuttons and radiobuttons look rather bad.

This restores the previous appearance by specifying selectColor
explicitly.  For light backgrounds we use white for selectColor, and
for dark backgrounds we use black.  The formula and threshold for
distinguishing light from dark are the same as used in tk_setPalette
for choosing the foreground color.

8d849957d8 gitk: Skip translation of "wrong Tcl version" message
We check the required Tcl version number before we setup msgcat for
language translation.  If the Tcl version is too old just display the
untranslated error text.

The caller of show_error can now pass an alternative function for mc.
The Tcl list function turns the translation into a no-op.

This fixes the error:
    Error in startup script: invalid command name "mc"

5c838d23aa gitk: Use the --submodule option for displaying diffs when available
When displaying diffs in a submodule, this makes gitk display the
headlines of the commits being diffed, instead of just showing
not-quite-helpful SHA-1 pairs, if the underlying git installation
supports this.  That makes it much easier to evaluate the changes, as
it eliminates the need to start a gitk inside the submodule and use
the superprojects hashes there to find out what the commits are about.

Since the --submodule option of git diff is new in git version 1.6.6,
this only uses the --submodule option when a git version of 1.6.6 or
higher is detected.

c21398be6d gitk: Show diff of commits at end of compare-commits output
When comparing a string of commits, when we find two non-merge commits
that differ, we now write the two commits to files and diff the files.
This pulls out the logic for creating a temporary directory from
external_diff into a separate procedure so that the new diffcommits
procedure can use it.

Because the diff command returns an exit status of 1 when the files
differ, and Tcl treats that as an error, this adds catch {} around the
close statements in getblobdiffline.

At present this only removes the temporary files when gitk exits.  It
should remove them when the diff is done.

9bf3acfada gitk: Parse arbitrary commit-ish in SHA1 field
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.

2b1fbf90aa 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.

097e111822 gitk: Do not hard-code "encoding" in attribute lookup functions
Commit 39ee47e (Clean up file encoding code and add enable/disable option,
2008-10-15) rewrote the attribute lookup functions gitattr and
cache_gitattr, but in the process hard-coded the attribute name "encoding"
instead of using the functions' parameters. This fixes it.

This is not a serious regression because currently all callers look only
for "encoding".

Further note that this fix assumes that future callers will not pass an
attribute name that contains regex special characters.

13d40b618a gitk: Make more options easily accessible from Edit View dialog
Commit 218a900bd8 added a number of new
individual fields for the Edit View dialog to make them more accessible
to end users, while still allowing all options to be specified in the

include refs, author, committer, commit message, and patch contents.
As before everything still remains accessible from the "arguments to
git log" input field.

Additionally, this provides hints for the format of the various input
fields (for example, listing some sample date strings in different
formats), and puts related query items into subsections to make it
easier to digest the number of options that exist.

6f63fc18b6 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.

010509f2de 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.

b9fdba7ff8 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.

52b8ea934e gitk: Fix possible infinite loop and display corruption
This fixes an issue reported by Johannes Sixt on the git mailing list:

> This recipe sends gitk into an endless loop. In git.git do:
>
> cd t
> # remove chmod a+x A near the end of the file
> sed -i 's/chmod/: chmod/' t3400-rebase.sh
> sh t3400-rebase.sh --debug
> cd trash\ directory.t3400-rebase/
> gitk master modechange modechange@{1}
>
>
> I briefly see the history chart, but the dot that should be modechange@{1}
> is missing. One automatically selected commit is shown in the diff section
> below. But then the commit list is cleared and gitk goes into an infinite
> loop.
>
> Things work alright if either modechange@{1} is dropped, or the 'chmod'
> line is left unchanged, which is a bit strange.
>
> This is with git version 1.6.1.2.390.gba743

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.
