Our file browser was showing bad output as it did not properly buffer
a partial record when read from `ls-tree -z`. This did not show up on
my Mac OS X system as most trees are small, the pipe buffers generally
big and `ls-tree -z` was generally fast enough that all data was ready
before Tcl started to read. However on my Cygwin system one of my
production repositories had a large enough tree and packfile that it
took a couple of pipe buffers for `ls-tree -z` to complete its dump.

Now that we are pretty strict about setting up own absolute paths to
any git helper (saving a marginal runtime cost to resolve the tool)
we can do the same in our console widget by making sure all console
execs go through git_read if they are a git subcommand, and if not
make sure they at least try to use the Tcl 2>@1 IO redirection if
possible, as it should be faster than |& cat.

Rather than making the C library search for git every time we want
to execute it we now search for the main git wrapper at startup, do
symlink resolution, and then always use the absolute path that we
found to execute the binary later on. This should save us some
cycles, especially on stat challenged systems like Cygwin/Win32.
While I was working on this change I also converted all of our
existing pipes ([open "| git ..."]) to use two new pipe wrapper
functions. These functions take additional options like --nice
and --stderr which instructs Tcl to take special action, like
running the underlying git program through `nice` (if available)
or redirect stderr to stdout for capture in Tcl.

Sometimes switching between branches can take more than a second or
two, in which case `git checkout` would normally have shown a small
progress meter to the user on the terminal to let them know that we
are in fact working, and give them a reasonable idea of when we may
finish.
We now do obtain that progress meter from read-tree -v and include
it in our main window's status bar. This allows users to see how
many files we have checked out, how many remain, and what percentage
of the operation is completed. It should help to keep users from
getting bored during a large checkout operation.

If the user double clicks a branch in the checkout dialog then they
probably want to start the checkout process on that branch. I found
myself doing this without realizing it, and of course it did nothing

This is a major rewrite of the way we perform switching between
branches and the subsequent update of the working directory. Like
core Git we now use a single code path to perform all changes: our
new checkout_op class. We also use it for branch creation/update
as it integrates the tracking branch fetch process along with a
very basic merge (fast-forward and reset only currently).
Because some users have literally hundreds of local branches we
use the standard revision picker (with its branch filtering tool)
to select the local branch, rather than keeping all of the local
branches in the Branch menu. The branch menu listing out all of
the available branches is simply not sane for those types of huge
repositories.
Users can now checkout a detached head by ticking off the option
in the checkout dialog. This option is off by default for the
obvious reason, but it can be easily enabled for any local branch
by simply checking it. We also detach the head if any non local
branch was selected, or if a revision expression was entered.

I'm really starting to dislike global variables. The ui_status_value
global varible is just one of those that seems to appear in a lot of
code and in many cases we didn't even declare it "global" within the
proc that updates it so we haven't always been getting all of the
updates we expected to see.
This change introduces two new global procs:
ui_status $msg; # Sets the status bar to show $msg.
ui_ready; # Changes the status bar to show "Ready."
The second (special) form is used because we often update the area
with this message once we are done processing a block of work and
want the user to know we have completed it.
I'm not fixing the cases that appear in lib/branch.tcl right now

In some workflows users will want to almost always just create a new
local branch that matches a remote branch. In this type of workflow
it is handy to have the new branch dialog default to "Match Tracking
Branch" and "Starting Revision"-Tracking Branch", with the focus in

of workflow at least two mouse clicks every time they create a new
local branch or switch to one with a fast-forward.

When trying to create a branch from a tag most people are looking

One of my production repositories has hundreds of remote tracking
branches. Trying to navigate these through a popup menu is just
not possible. The list is far larger than the screen and it does
not scroll fast enough to efficiently select a branch name when
trying to create a branch or delete a branch.
This is major rewrite of the revision chooser mega-widget. We
now use a single listbox for all three major types of named refs
(heads, tracking branches, tags) and a radio button group to pick
which of those namespaces should be shown in the listbox. A filter
field is shown to the right allowing the end-user to key in a glob
specification to filter the list they are viewing. The filter is
always taken as substring, so we assume * both starts and ends the
pattern the user wanted but otherwise treat it as a glob pattern.
This new picker works out really nicely. What used to take me at
least a minute to find and select a branch now takes mere seconds.

If the user elects to create a local branch that has the same name
as an existing branch and we can fast-forward the local branch to
the selected revision we might as well do the fast-forward for the
user, rather than making them first switch to the branch then merge
the selected revision into it. After all, its really just a fast
forward. No history is lost. The resulting branch checkout may
also be faster if the branch we are switching from is closer to
the new revision.
Likewise we also now allow the user to reset the local branch if
it already exists but would not fast-forward. However before we
do the actual reset we tell the user what commits they are going to
lose by showing the oneline subject and abbreviated sha1, and we also
let them inspect the range of commits in gitk.

Some workflows have users create a local branch that matches a remote
branch they have fetched from another repository. If the user wants
to push their changes back to that remote repository then they probably
want to use the same branch name locally so that git-gui's push dialog
can setup the push refspec automatically.
To prevent typos with the local branch name we now offer an option to
use the remote tracking branch name as the new local branch name.

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)

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.

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.

Our blame viewer only grabbed the first initial of the git.git

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

Because Tk does not assure us the order that it will process

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).

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.

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

the original location data (the slower -M -C -C pass) as that is
usually more fine-grained than the current location data.

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
