This replaces a lot of code that used the result from several 2-way
diffs to generate a combined diff for a merge. Now we just use
git-diff-tree --cc and colorize the output a bit, which is a lot
simpler, and has the enormous advantage that if the diff doesn't
show quite what someone thinks it should show, I can deflect the
blame to someone else. :)

Apparently this simplifies things for the parser/compiler and makes
it go slightly faster (since without the braces, it potentially has
to do two levels of substitutions rather than one).

This uses a table of encoding names and aliases distilled from
http://www.iana.org/assignments/character-sets plus some heuristics
to convert standard encoding names to ones that Tcl recognizes.

This should be more robust in the case that some does "Update" before
the initial drawing is finished. It also avoids having to reset the
list of children for each commit and reconstruct it.

The change in 8b7e5d76e836396a097bb6f61cf930ea872a7bd3, which makes
a couple of git-diff-tree calls supply only one id rather than two,
fixes the display when showing what a single commit did with dense
revlists, but broke the diff this->selected and diff selected->this
right-click menu functions.
Yann Dirson pointed this out and had a patch that fixed the diff
menu functions by passing a "singlecommit" flag around. This fixes
it a bit differently, by making the ids and diffids variables be
either a single id, in the case of showing what a commit did, or
{oldid newid}, in the case of the diff menu functions. That way
we can just pass $ids to git-diff-tree as is. Most of the changes
in fact are just reversing the order of ids in $ids and $diffids,
because they used to be {child parent}, but git-diff-tree requires
old id before new id.

It has a fatal flaw in that it only handles timezones that are a
multiple of an hour. It's really only needed with Tk8.5, where
the clock format command has been reimplemented in Tcl and is much
slower than in Tk8.4.

Commits that weren't read from git-rev-list, i.e. the ones displayed
with an open circle, were displayed incorrectly: the headline was
null if there was only one line, and the commit comment was put all
on one line. Also, the terminal commits weren't displayed when -r
was used.

gitk switched to use git-diff-tree with one argument in gettreediffs and
getblobdiffs. git-diff-tree with one argument outputs commit ID in from
of the patch. This causes an empty line after "Comments" in the lower
right pane. Also, the diff in the lower left pane has the commit ID,
which is useless there.
This patch makes git use the newly added -no-commit-id option for
git-diff-tree to suppress commit ID. It also removes the p variable in
both functions, since it has become useless after switching to the
one-argument invocation for git-diff-tree.

The -r flag means "rev-list order", i.e. just display the commits
in the order they come from git-rev-list.
The speedups include:
- don't process the whole commit line-by-line, only the header
- don't convert dates when reading the commits, rather do it when
needed
- don't do the $canv delete lines.$id in drawlines when drawing the
graph initially (it was taking a lot of the total time)
- cache the date conversion for each hour (more important with tk8.5,
since [clock format] is a lot slower in 8.5 than in 8.4).

To generate the diff for a commit, gitk used to do
git-diff-tree -p -C $p $id
(and same thing to generate filenames, except using just "-r" there) which
does actually generate the diff from the parent to the $id, exactly like
it meant to do.
However, that really sucks with --dense, where the "parent" information
has all been rewritten to point to the previous commit. The diff actually
works exactly right, but now it's the diff of the _whole_ sequence of
commits all the way to the previous commit that last changed the file(s)
that we are looking at.
And that's really not what we want 99.9% of the time, even if it may be
perfectly sensible. Not only will the diff not actually match the commit
message, but it will usually be _huge_, and all of it will be totally
uninteresting to us, since we were only interested in a particular set of
files.
It also doesn't match what we do when we write the patch to a file.
So this makes gitk just show the diff of _that_ commit.
We might even want to have some way to limit the diff to only the
filenames we're interested in, but it's often nice to see what else
changed at the same time, so that's secondary.
The merge diff handling is left alone, although I think that should also
be changed to only look at what that _particular_ merge did, not what it
did when compared to the faked-out parents.

This just displays the result of git-cat-file on the tag in the
details pane. If the tag is a "direct" tag (the tag file contains
the SHA1 ID of a commit rather than a tag), we show the tag name
and SHA1 ID.

These are features requested by Junio. Any plain file under .git/refs
whose contents start with 40 hex characters is taken as a reference
and displayed like a head but with a light blue background (unless it
is in .git/refs/tags or .git/refs/heads, in which case it is displayed
as before). There is now a "Reread references" menu item in the File
menu which re-reads all the plain files under .git/refs and redisplays
any references that have changed.

This problem was revealed by running gitk --all on Wolfgang Denk's
u-boot repository.

With --parents, git-rev-list gives us the list of parents on the
first line of each commit. We use that rather than looking for
the parent: lines in the commit body, since this way we get to
know about the grafts for free.
|
|
When the graph gets too wide (as defined by the maxwidth variable,
which can be set in ~/.gitk), we can now terminate graph lines with
an arrow pointing downwards, and reintroduce them later with an
arrow pointing upwards when we need them. This makes the graph much
less cluttered on large repositories such as the linux kernel.
Unfortunately this has made it slower; it takes about 10 seconds
user time on the linux-2.6 repository on my machine now, compared
to 6 seconds before. I'll have to work on optimizing that. Also
on the todo list are making the arrow heads active (so if you click
on them you jump to the other end) and improving the placement of
the null entry.
|

We read .git/info/grafts and use the information in there to
override the list of parents we get from git-rev-list or
git-cat-file.
|
|
The previous commit improved performance a lot but also meant that
we waited longer to see something drawn. This refines the heuristics
for when to call update so that (1) when we have finished processing
a bufferfull of information from git-rev-list, we call update if
enough time has elapsed, regardless of how many commits we've drawn,
and (2) the number of commits drawn between updates scales with the
total number of commits drawn: 1 for 1-99 commits, 10 for 100-9999
commits, or 100 for >= 10000 commits.
|
|
On a large repository with > 60,000 commits, each call to the Tk
update primitive (which gives Tk a chance to respond to events and
redraw the screen) was taking up to 0.2 seconds. Because the logic
was to call update after drawing a commit if 0.1 seconds had passed
since the last update call, we were calling it for every commit,
which was slowing us down enormously. Now we also require that we
have drawn 100 commits since the last update (as well as it being
at least 0.1 seconds since the last update). Drawing 100 commits
takes around 0.1 - 0.2 seconds (even in this large repo) on my G5.

This adds "Child: " lines to the commit window, which tells what children
a commit has.
It also cleans things up: it marks the text widget as no-wrap, which means
that it doesn't need to truncate the commit description arbitrarily by
hand. Also, the description itself is now done by a common helper routine
that handles both the parent and the children.

Now the history remembers when we have clicked on a graph line
and when we have asked for a diff between two commits, as well
as when we have displayed a commit.
The display when you click on a graph line now uses clickable
SHA1 IDs instead of the embedded "Go" buttons. Also made the
IDs clickable in the header for a diff between two commits.

This adds a useful "Parent:" line to the git commit information window.

where all the parent commit ID's are clickable, because the new lines are
added as part of the "comment" string, and thus the regular clickability
thing will match them automatically.

The effect of this is that it allows Tcl to do the locale-specific
conversion of the input data to its internal unicode representation.
That means that commit messages in Russian or other languages should
be displayed correctly now (according to the locale that is in effect.)
|
|
This is based on suggestions by Jeff Epler and Linus Torvalds, but
extended so that we do the switching between the watch cursor and
the normal cursor correctly as well.
Also fixed a bug pointed out by Junio Hamano - I wasn't incrementing
the link number (duh!).
|
|
When we display the commit message in the details pane, any string
of 40 [0-9a-f] characters that corresponds to a SHA1 ID that we
know about gets turned into a clickable link, and displayed in
blue and underlined.
We now keep a history of commits that we have looked at, and we
have forward and back buttons for moving within the history list.
|
|
If the graph gets to use more than a certain percentage (default 50%)
of the width of the top-left pane, we now reduce the amount of space
allowed for each graph line. This means it doesn't look quite as
nice but you can still see the headline for the commit. (Currently
the only way to customize the percentage is to edit your ~/.gitk
file manually.)
|
|
Specifically this should fix the following errors:
wrong # args: should be "startdiff ids" (fix from Junio Hamano)
can't read "filelines(....)": no such element in array
can't unset "treepending": no such variable
|
|
Now we see if the result is quite similar to one of the parents, and
if it is, display the result as a diff from that parent. If the result
is similar to more than one parent, pick the one that it's most
similar to.

Some places assumed .git is the GIT_DIR, resulting heads and
tags not showing when it was run like "GIT_DIR=. gitk --all".

my private copy of git.git repository before pushing it out.
Define a single procedure "gitdir" and use it.

Stuff that ended up in the result is shown in bold with a "+" at the
beginning of the line; stuff that didn't is in the normal font with
a "-" at the beginning of the line. The color shows which parent
the stuff was in; red for the first parent, blue for the second, then
green, purple, brown, and the rest are grey. If the result is different
from all of the parents it is shown in black (and bold).
|
|
|
|
If there is a GCA for the parents of the merge, then a file is
interesting if some parent has a version that is different from both
the child and the GCA. If there is no GCA (e.g. for a merge that
pulls in an external project) then a file is interesting if the child's
version is different from all of the parents.
Next step is to actually show the differences for the interesting
files...
|
|
The old style is still available as an option (we still need a
preferences window so we can set/clear it though).
|
|
|
|
Also simplified the parsing of the git-diff-tree -p output and got
rid of the unused 'seenfile' variable.
|
|
We display the files where the child differs from the first parent
first in black in the file list window, followed by the second parent
in blue, and so on using different colors for each parent (provided
you don't have more than 6 parents; if you do we cycle around).
