79a060e477 git-gui: Maintain remote and source ref for tracking branches
In the next change I want to let the user create their local branch
name to match the remote branch name, so that the existing push
dialog can push the branch back up to the remote repository without
needing to do any sort of remapping.  To do that we need to know
exactly what branch name the remote system is using.

So all_tracking_branches returns a list of specifications, where
each specification is itself a list of:

  - local ref name (destination we fetch into)
  - remote name (repository we fetch from)
  - remote ref name (source ref we fetch from)

6f2a3fc812 git-gui: Optimize for newstyle refs/remotes layout
Most people using Git 1.5.x and later are using the newer style
of remotes layout where all of their tracking branches are in
refs/remotes and refs/heads contains only the user's own local
branches.

In such a situation we can avoid calling is_tracking_branch
for each head we are considering because we know that all of
the heads must be local branches if no fetch option or Pull:
line maps a branch into that namespace.

If however any remote maps a remote branch into a local
tracking branch that resides in refs/heads we do exactly
what we did before, which requires scanning through all
fetch lines in case any patterns are matched.

I also switched some regexp/regsub calls to string match
as this can be a faster operation for prefix matching.

b1fa2bfff3 git-gui: Abstract the revision picker into a mega widget
This rather large change pulls the "Starting Revision" part of the
new branch dialog into a mega widget that we can use anytime we
need to select a commit SHA-1.  To make use of the mega widget I
have also refactored the branch dialog to use the class system,
much like the delete remote branch dialog already does.

6233ab1729 git-gui: Teach class system to support [$this cmd] syntax
Its handy to be able to ask an object to do something for you by
handing it a subcommand.  For example if we want to get the value
of an object's private field the object could expose a method that
would return that value.  Application level code can then invoke
"$inst get" to perform the method call.

Tk uses this pattern for all of its widgets, so we'd certainly
like to use it for our own mega-widgets that we might develop.
Up until now we haven't needed such functionality, but I'm working
on a new revision picker mega-widget that would benefit from it.

To make this work we have to change the definition of $this to
actually be a procedure within the namespace.  By making $this a
procedure any caller that has $this can call subcommands by passing
them as the first argument to $this.  That subcommand then needs
to call the proper subroutine.

Placing the dispatch procedure into the object's variable namespace
ensures that it will always be deleted when the object is deleted.

88dce86f38 git-gui: Skip nicknames when selecting author initials
Our blame viewer only grabbed the first initial of the git.git
author string "Simon 'corecode' Schubert".  Here the problem was we
looked at Simon, pulled the S into the author initials, then saw
the single quote as the start of the next name and did not like
this character as it was not an uppercase letter.

We now skip over single quoted nicknames placed within the author
name field and grab the initials following it.  So the above name
will get the initials SS, rather than just S.

d4c5307701 git-gui: Honor rerere.enabled configuration option
Recently in git.git change b4372ef136 Johannes Schindelin taught
git-commit.sh to invoke (or skip) calling git-rerere based upon
the rerere.enabled configuration setting:

  So, check the config variable "rerere.enabled". If it is set
  to "false" explicitely, do not activate rerere, even if
  .git/rr-cache exists. This should help when you want to disable
  rerere temporarily.

  If "rerere.enabled" is not set at all, fall back to detection
  of the directory .git/rr-cache.

We now do the same logic in git-gui's own commit implementation.

47282d4646 git-gui: Ensure windows shortcuts always have .bat extension
Apparently under some setups on Windows Tk is hiding our file
extension recommendation of ".bat" from the user and that is
allowing the user to create a shortcut file which has no file
extension.  Double clicking on such a file in Windows Explorer
brings up the associate file dialog, as Windows does not know
what application to launch.

We now append the file extension ".bat" to the filename of the
shortcut file if it has no extension or if it has one but it is
not ".bat".

1eb96a25c9 git-gui: Correct resizing of remote branch delete dialog
The status field of the remote branch delete dialog was marked to
expand, which meant that if the user grew the window vertically
most of the new vertical height was given to the status field and
not to the branch list.  Since the status field is just a single
line of text there is no reason for it to gain additional height,
instead we should make sure all additional height goes to the
branch list.

c1fd897a25 git-gui: Start blame windows as tall as possible
Most users these days are using a windowing system attached to a
monitor that has more than 600 pixels worth of vertical space
available for application use.  As most files stored by Git are
longer than they are wide (have more lines than columns) we want
to dedicate as much vertical space as we can to the viewer.

Instead of always starting the window at ~600 pixels high we now
start the window 100 pixels shorter than the screen claims it has
available to it.  This -100 rule is used because some popular OSen
add menu bars at the top of the monitor, and docks on the bottom
(e.g. Mac OS X, CDE, KDE).  We want to avoid making our window too
big and causing the window's resize control from being out of reach
of the user.

The blame viewer is composed of two different areas, the file

trying to shift the focus it is probably because they want to
shift from one area to the other, so we just setup Tab and

39fa2a983d git-gui: Save geometry before the window layout is damaged
Because Tk does not assure us the order that it will process
children in before it destroys the main toplevel we cannot safely
save our geometry data during a "bind . <Destroy>" event binding.
The geometry may have already changed as a result of a one or
more children being removed from the layout.  This was pointed
out in gitk by Mark Levedahl, and patched over there by commit
b6047c5a81.

So we now also use "wm protocol . WM_DELETE_WINDOW" to detect when
the window is closed by the user, and forward that close event to
our main do_quit routine.

0f32da53df git-gui: Favor the original annotations over the recent ones
Usually when you are looking at blame annotations for a region of
a file you are more interested in why something was originally
done then why it is here now.  This is because most of the time
when we get original annotation data we are looking at a simple
refactoring performed to better organize code, not to change its
semantic meaning or function.  Reorganizations are sometimes of
interest, but not usually.

We now show the original commit data first in the tooltip.  This
actually looks quite nice as the original commit will usually have an
author date prior to the current (aka move/copy) annotation's commit,
so the two commits will now tend to appear in chronological order.

I also found myself to always be clicking on the line of interest
in the file column but I always wanted the original tracking data
and not the move/copy data.  So I changed our default commit from
$asim_data (the simple move/copy annotation) to the more complex
$amov_data (the -M -C -C original annotation).

949da61b9b git-gui: Improve our labeling of blame annotation types
It feels wrong to call the -M -C -C annotations "move/copy tracking"
as they are actually the original locations.  So I'm relabeling
the status bar to show "copy/move tracking annotations" for the
current file (no -M -C -C) as that set of annotations tells us who
put the hunk here (who moved/copied it).  I'm now calling the -M
-C -C pass "original location annotations" as that's what we're
really digging for.

I also tried to clarify some of the text in the hover tooltip.

5d198d6766 git-gui: Use three colors for the blame viewer background
To prevent neighboring lines that are different commits from using
the same background color we now use 3 colors and assign them
by selecting the color that is not used before or after the line
in question.  We still color "on the fly" as we receive hunks from
git-blame, but we delay our color decisions until we are getting
the original location data (the slower -M -C -C pass) as that is
usually more fine-grained than the current location data.

Credit goes to Martin Waitz for the tri-coloring concept.

0dfed77b3c git-gui: Jump to original line in blame viewer
When the user clicks on a commit link within one of the columns
in the blame viewer we now jump them not just to that commit/file
pair but also to the line of the original file.  This saves the
user a lot of time, as they don't need to search through the new
file data for the chunk they were previously looking at.

We also restore the prior view when the user clicks the back button
to return to a pior commit/file pair that they were looking at.

Turned out this was quite tricky to get working in Tk.  Every time
I tried to jump the text widgets to the correct locations by way
of the "yview moveto" or "see" subcommands Tk performed the change
until the current event finished dispatching, and then reset the
views back to 0, making the change never take place.  Forcing Tk
to run the pending events before we jump the UI resolves the issue.

172c92b475 git-gui: Run blame twice on the same file and display both outputs
We now perform two passes over any input file given to the blame
viewer.  Our first pass is a quick "git-blame" with no options,
getting the details of how each line arrived into this file.  We
are specifically ignoring/omitting the rename detection logic as
this first pass is to determine why things got into the state they
are in.

Once the first pass is complete and is displayed in the UI we run
a second pass, using the much more CPU intensive "-M -C -C" options
to perform extensive rename/movement detection.  The output of this
second pass is shown in a different column, allowing the user to see
for any given line how it got to be, and if it came from somewhere
else, where that is.

This is actually very instructive when run on our own lib/branch.tcl
script.  That file grew recently out of a very large block of code
in git-gui.sh.  The first pass shows when I created that file, while
the second pass shows the original commit information.

fc816d7b85 git-gui: Rename fields in blame viewer to better descriptions
Calling the commit message pane $w_cmit is a tad confusing when
we also have the $w_cgrp column that shows the abbreviated SHA-1s.

So w_cmit -> w_cviewer, as it is the "commit viewer"; and
w_cgrp -> w_amov as it is the "annotated commit + move tracking"
column.  Also changed line_data -> amov_data, as that list is
exactly the results shown in w_amov.

Why call the column "move tracking"?  Because this column holds
data from "git blame -M -C".  I'm considering adding an additional
column that holds the data from "git blame" without -M/-C, showing
who did the copy/move, and when they did it.

2f85b7e4b4 git-gui: Switch internal blame structure to Tcl lists
The Tcl list datatype is significantly faster to work with than
the array type, especially if our indexes are a consecutive set
of numbers, like say line numbers in a file.

This rather large change reorganizes the internal data structure
of the blame viewer to use a proper Tcl list for the annotation
information about a line.  Each line is given its own list within
the larger line_data list, where the indexes correspond to various
facts about that particular line.

The interface does seem to be more responsive this way, with less
time required by Tcl to process blame, and to switch to another
version of the same file.  It could just be a placebo effect, but
either way most Tcl experts perfer lists for this type of work over
arrays.

order each commit was received in.  Recent changes have removed
that need for an ordering and the "order" array is now just a

The colors were moved to fields, so they appear inside of the
blame viewer instance.  This keeps two different concurrently
running blame viewers from stepping on each other's ordering
of the colors in group_colors.

Most of the other fields were moved around a little bit so
that they are organized by major category and value lifespan.

Any file over our default allowance of 5 digits (99,999 lines)

out is trivial compared to the time it will take Git to fully do
the annotations.

Most source code files are under 9,999 lines of text, so using a

Unfortunately when I added the right margin earlier (when I removed
the padding) I ate into the extra character's space, losing the left
margin.  This put the line numbers too close to the commit column in
any file with more than 999 lines in it.

063257076d git-gui: Remove unnecessary space between columns in blame viewer
On Mac OS X the OS has "features" that like to draw thick black
borders around the text field that has focus.  This is nice if
you want to know where your text is going and are blind as a bat,
but it isn't the best thing to have in a table that is being
faked through the abuse of Tk text widgets.

By setting our takefocus, highlightthickness and padx/y we can
get rid of this border and get our text widgets packed right next
to each other, with no padding between them.  This makes the blame
background color smoothly run across the entire line of commit data,
line number and file content.

0eab69a4a9 git-gui: Remove the loaded column from the blame viewer
Originally I had placed this loaded column between the line number
and the file line data to help users know if a particular line has
received annotation data or not yet.  This way users would know if
the line(s) they were interested in were ready for viewing, or if
they still had to wait.  It also was an entertaining way for the
user to spend their time waiting for git-blame --incremental to
compute the complete set of annotations.

However it is completely useless now that we show the abbreviated
commit SHA-1 and author initials in the leftmost column.  That area
is empty until we get the annotation data, and as soon as we get it
in we display something there, indicating to the user that there is
now blame data ready.  Further with the tooltips the user is likely
to see the data as soon as it comes in, as they are probably not
keeping their mouse perfectly still.  So I'm removing the field to
save screen space for more useful things, like file content.

b55a243dfc git-gui: Clip the commit summaries in the blame history menu
Some commit lines can get really long when users enter a lot of
text without linewrapping (for example).  Rather than letting the
menu get out of control in terms of width we clip the summary to
the first 50+ characters.

08dda17e00 git-gui: Use a label instead of a button for the back button
Apparently Tk on Mac OS X won't draw a button with an image using a
transparent background.  Instead it draws the button using some sort
of 3D effect, even though I asked for no relief and no border.  The
background is also not our orange that we expected it to be.

Earlier I had tried this same trick on Windows and it draws the same
way as the button did, so I'm going to switch to the label as that
seems to be more portable.

79c50bf3ee git-gui: Show original filename in blame tooltip
If we have two commits right next to each other in the final
file and they were kept as different blocks in the leftmost
column then its probably because the original filename was
different.  To help the user know where they are digging into
when they click on that link we now show the original file in
the tooltip, but to save space we do so only if the original
file is not the same as the file we are currently viewing.

669fbc3d09 git-gui: Combine blame groups only if commit and filename match
Consecutive chunks of a file could come from the same commit, but
have different original file names.  Previously we would have put
them into a single group, but then the hyperlink would jump to only
one of the files, and the other would not be accessible.  Now we can
get to the other file too.

22c6769d91 git-gui: Allow digging through history in blame viewer
gitweb has long had a feature where the user can click on any
commit the blame display and go visit that commit's information
page.  From the user could go get the blame display for the file
they are tracking, and try to digg through the history of any
part of the code they are interested in seeing.

We now offer somewhat similiar functionality in git-gui.  The 4
digit commit abreviation in the first column of our blame view is
now offered as a hyperlink if the commit isn't the one we are now
viewing the blame output for (as there is no point in linking back
to yourself).  Clicking on that link will stop the current blame
engine (if still running), push the new target commit onto the
history stack, and restart the blame viewer at that commit, using
the "original file name" as supplied by git-blame for that chunk
of the output.

Users can navigate back to a version they had been viewing before
by way of a back button, which offers the prior commits in a popup
menu displayed right below the back button.  I'm always showing the
menu here as the cost of switching between views is very high; you
don't want to jump to a commit you are not interested in looking at
again.

During switches we throw away all data except the cached commit data,
as that is relatively small compared to most source files and their
annotation marks.  Unfortunately throwing this per-file data away in
Tcl seems to take some time; I probably should move the line indexed
arrays to proper lists and use [lindex] rather than the array lookup
(usually lists are faster).

We now start the git-blame process using "nice", so that its priority
will drop hopefully below our own.  If I don't do this the blame engine
gets a lot of CPU under Windows 2000 and the git-gui user interface is
almost non-responsive, even though Tcl is just sitting there waiting
for events.

982cf98fa4 git-gui: Display a progress bar during blame annotation gathering
Computing the blame records for a large file with a long project
history can take git a while to run; traditionally we have shown
a little meter in the status area of our blame viewer that lets
the user know how many lines have been finished, and how far we
are through the process.

Usually such progress indicators are drawn with a little progress
bar in the window, where the bar shows how much has been completed
and hides itself when the process is complete.  I'm using a very
simple hack to do that: draw a canvas with a filled rectangle.

Of course the time remaining has absolutely no relationship to the
progress meter.  It could take very little time for git-blame to get
the first 90% of the file, and then it could take many times that to
get the remaining 10%.  So the progress meter doesn't really have any
sort of assurances that it relates to the true progress of the work.
But in practice on some ugly history it does seem to hold a reasonable
indicator to the completion status.  Besides, its amusing to watch and
that keeps the user from realizing git is being somewhat slow.

d0b741dc08 git-gui: Allow the user to control the blame/commit split point
At one point I tried to present the blame viewer to an audience of
people on a 640 by 480 pixel LCD projector.  This did not work at
all as the top area (the file data) was taking up all of the screen
realestate and the split point was not adjustable by the user.  In
general locking the user into a specific ratio of display is just
not user friendly.

So we now place a split pane control into the middle of our blame
window, so the user can adjust it to their current needs.  If the
window increases (or decreases) in height we assign the difference
to the file data area, as that is generally the area of the window
that users are trying to see more of when they grow the window.

Unfortunately there appears to be a bug in the "pack" layout manager
in Tcl/Tk 8.4.1.  The status bar and the lower commit pane was being
squashed if the window decreased in height.  I think the pack manager
was just not decreasing the size of the panedwindow slave properly if
the main window shrank.  Switching to the "grid" layout manager fixes
the problem, but is slightly uglier setup code.
