8809d691ec [PATCH] gitk: Add horizontal scrollbar to the diff view
Adding horizontal scroll bar makes the scrolling feature more
discoverable to the users.  The horizontal scrollbar is a bit narrower
than vertical ones so we don't make too big impact on available screen
real estate.  The text and scrollbar widget layout is done using grid
geometry manager.

An interesting side effect of Tk scrollbars is that the "elevator"
size changes depending on the visible content. So the horizontal
scrollbar "elevator" changes as the user scrolls the view up and down.

95293b58eb [PATCH] gitk: make autoselect optional
Whenever a commit is selected in the graph pane, its SHA1 is
automatically put into the selection buffer for cut and paste.
However, some users may find this behavior annoying since it can
overwrite something they actually wanted to keep in the buffer.

This makes the behavior optional under the name "Auto-select SHA1",
but continues to default to "on".

2d48085661 [PATCH] Add an --argscmd flag to get the list of refs to show
This allows gitk to be used to display a different set of refs each
the display is refreshed.  This is useful when gitk is called from
other porcelain suites, for doing such things as displaying the set of
patches in a patch stack.

The user specifies a command as the argument to the --argscmd option.
The command is run initially and each time the display is refreshed,
and is expected to generate a list of commit IDs, one per line.  Those
commits are appended to the commits passed on the command-line when
constructing the git log command to be executed.

The command is considered to be an attribute of a view, and has its
own field in the saved view, and an edit field in the view editor.

b9bee11526 gitk: Only restore window size from ~/.gitk, not position
This also limits the window size to the screen size.  That is better
than nothing, but it isn't perfect, since ideally we would take into
account window decorations, and things such as gnome panels or the
Mac OS X dock and menu bar, but I don't know how to do that.

On Cygwin this is as good as restoring the whole geometry (size and
position) at working around the Cygwin Tk bugs, according to Mark
Levedahl.

1407ade93c [PATCH] gitk: learn --show-all output
It's really not very easy to visualize the commit walker,
because - on purpose - it obvously doesn't show the

We will soon add a "--show-all" flag to the revision walker,

This is to update 'gitk' to show those negative commits in gray

48750d6a84 [PATCH] gitk: properly deal with tag names containing / (slash)
When creating a tag through gitk, and the tag name includes a slash (or
slashes), gitk errors out in a popup window.  This patch makes gitk use
'git tag' to create the tag instead of modifying files in refs/tags/,
which fixes the issue; if 'git tag' throws an error, gitk pops up with
the error message.

b9b86007e2 [PATCH] gitk: Add checkbutton to ignore space changes
Ignoring space changes can be helpful.  For example, a commit
claims to only reformat source code and you quickly want to
verify if this claim is true.  Or a commit accidentally changes
code formatting and you want to focus on the real changes.

In such cases a button to toggle of whitespace changes would be
quite handy.  You could quickly toggle between seeing and
ignoring whitespace changes.

This commit adds such a checkbutton right above the diff view.

However, in general it is a good thing to see whitespace changes
and therefore the state of the checkbutton is not saved. For
example, space changes might happen unintentionally.  But they are
real changes yielding different sha1s for the blobs involved.

7a39a17a87 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.

e5ef6f952a gitk: Fix "can't unset prevlines(...)" Tcl error
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.

5e85ec4cd0 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.

32f1b3e4a4 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.

3e6b893f33 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.

f56782aef4 gitk: Fix bugs in setting rowfinal
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.

f5f3c2e29f 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.

5cd15b6b7f gitk: Add a cache for the topology info
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.
