If the horizontal scrollbar isn't currently visible (because it has
not been needed) but we get an update to the scroll port we may find
the scrollbar window exists but the Tcl command doesn't. Apparently
it is possible for Tk to have partially destroyed the scrollbar by
removing the Tcl procedure name but still leaving the widget name in
the window registry.

The code we use to test if a hook is executable or not differs on
Cygwin from the normal POSIX case. Rather then repeating that for
all three hooks we call in our commit code path we can place the
common logic into a global procedure and invoke it when necessary.
This also lets us get rid of the ugly "|& cat" we were using before
as we can now rely on the Tcl 8.4 feature of "2>@1" or fallback to
the "|& cat" when necessary.
The post-commit hook is now run through the same API, but its outcome
does not influence the commit status. As a result we now show any of
the errors from the post-commit hook in a dialog window, instead of on
the user's tty that was used to launch git-gui. This resolves a long
standing bug related to not getting errors out of the post-commit hook
when launched under git-gui.

Under core Git the git-commit tool will invoke the commit-msg hook
if it exists and is executable to the user running git-commit. As
a hook it has some limited value as it cannot alter the commit, but
it can modify the message the user is attempting to commit. It is
also able to examine the message to ensure it conforms to some local
standards/conventions.
Since the hook takes the name of a temporary file holding the message
as its only parameter we need to move the code that creates the temp
file up earlier in our commit code path, and then pass through that
file name to the latest stage (where we call git-commit-tree). We let
the hook alter the file as it sees fit and we don't bother to look at
its content again until the commit succeeded and we need the subject
for the reflog update.

If we apply a hunk in either direction this may change the file's
status. For example if a file is completely unstaged, and has at
least two hunks in it and the user stages one hunk the file will
change from "Modified, not staged" to "Portions staged for commit".
Resetting the file path causes our trace on this variable to fire;
that trace is used to update the file header in the diff viewer to
the file's current status.

Often users setup a few source files and get a project rolling
before they create a Git repository for it. In such cases the
core Git tools allow users to initialize a new repository by
simply running `git init` at the desired root level directory.
We need to allow the same situation in git-gui; if the user is
trying to make a new repository we should let them do that to any
location they chose. If the directory already exists and already
has files contained within it we still should allow the user to
create a repository there. However we still need to disallow
creating a repository on top of an existing repository.

If the user tries to clone a Git repository that is actually a

On Windows its better to use a shortcut (.lnk file) over a batch
script (.bat) as we can specify the icon file for the .lnk and
thus have these git specific objects appear on the desktop with
that git specific icon file.
Unfortunately the authors of Tcl did not bless us with the APIs
needed to create shortcuts from within Tcl. But Microsoft did
give us Windows Scripting Host which allows us to execute some
JavaScript that calls some sort of COM object that can operate
on a .lnk file.
We now build both Cygwin and non-Cygwin "desktop icons" as proper
Windows .lnk files, using the "Start in" property of these files
to indicate the working directory of the repository the user wants

We now place all of the commands related to fetching and pushing of
changes into a single "Remote" menu. This way we have a better class
of bucket that we can drop additional remote related items into such
as doing a remote merge or editing the remote configuration specs.

unable to know when git-update-index has processed the data we fed to

Henrik came up with this alternative logo for gitweb and posted
it on his blog:
http://henrik.nyh.se/2007/06/alternative-git-logo-and-favicon
The msysGit port uses his logo within some of their components,
and frankly it looks better here in git-gui for our repository
setup wizard screen. The logo fits quite nicely along the left
edge of our window, leaving significantly more vertical space
for things like the git-fetch console output.
Because the logo changes the layout charateristics of the setup
window I also needed to adjust some of the padding for our widgets
and stop using a fixed width window size. We now let Tk compute
the correct size of the main window whenever the layout changes,
and drop the window into roughly the upper left 1/3 of the desktop
so its not quite centered but is likely to be far enough away from
any sort of task bars/menu bars/docks that the user may have along
any edge of the screen.

If we have added a scrollbar to the console window because one

If the console finishes displaying its output and is "done" but

is possible for Tk to delete the window namespace before it does
the text widget updates, which means we are unable to add the
horizontal or vertical scrollbar to the window when the text
widget decides it cannot draw all glyphs on screen.
We need to delay deleting the window namespace until we know
the window is not going to ever be used again. This occurs if
we are done receiving output, the command is successful and the
window is closed, or if the window is open and the user chooses
to close the window after the command has completed.

If the source repository is using an objects/info/alternates file
we need to copy the file to our new repository so that it can access
any objects that won't be copied/hardlinked as they are stored in the
alternate location.
We explicitly resolve all paths in the objects/info/alternates as
relative to the source repository but then convert them into an
absolute path for the new clone. This allows the new clone to
access the exact same locaton as the source repository, even if
relative paths had been used before.
Under Cygwin we assume that Git is Cygwin based and that the paths
in objects/info/alternates must be valid Cygwin UNIX paths, so we
need to run `cygpath --unix` on each line in the alternate list.

If we are doing a "standard" clone by way of hardlinking the

need to wait for both the NT overheads and the network.

If we are started outside of a git repository than it is likely
the user started us from some sort of desktop shortcut icon in
the operating system. In such a case the user is expecting us to
prompt them to locate the git repository they want to work on,
or to help them make a new repository, or to clone one from an
existing location. This is a very simple wizard that offers the
user one of these three choices.
When we clone a repository we always use the name `master` in the
local repository, even if the remote side does not appear to point
to that name. I chose this as a policy decision. Much of the Git
documentation talks about `master` being the default branch in a
repository and that's what git-init does too. If the remote side
doesn't call its default branch `master` most users just don't care,
they just want to use Git the way the documentation describes.
Rather than relying on the git-clone Porcelain that ships with
git we build the new repository ourselves and then obtain content
by git-fetch. This technique simplifies the entire clone process
to roughly: `git init && git fetch && git pull`. Today we use
three passes with git-fetch; the first pass gets us the bulk of
the objects and the branches, the second pass gets us the tags,
and the final pass gets us the current value of HEAD to initialize
the default branch.
If the source repository is on the local disk we try to use a
hardlink to connect the objects into the new clone as this can
be many times faster than copying the objects or packing them and
passing the data through a pipe to index-pack. Unlike git-clone
we stick to pure Tcl [file link -hard] operation thus avoiding the
need to fork a cpio process to setup the hardlinks. If hardlinks
do not appear to be supported (e.g. filesystem doesn't allow them or
we are crossing filesystem boundaries) we use file copying instead.

Sometimes we use a Tk text widget as though it were a listbox.
This happens typically when we want to show an icon to the left
of the text label or just when a text widget is generally a better
choice then the native listbox widget.
In these cases if we want the user to have control over the selection
we implement our own "in_sel" tag that shows the selected region
and we perform our own selection management in the background
via keybindings and mouse bindings. In such uses we don't want
the user to be able to activate the native platform selection by
dragging their mouse through the text widget. Doing so creates a
very confusing display and the user is left wondering what it may
mean to have two different types of selection in the same widget.
Tk doesn't allow us to delete the "sel" tag that it uses internally
to manage the native selection but it will allow us to make it
invisible by setting the tag to have the same display properties
as unselected text. So long as we don't actually use the "sel"
tag for anything in code its effectively invisible.

The Tcl expression "[append [mc Foo] Bar]" does not return the string
"FooBar" after translation; instead it is setting the variable Foo to
the value Bar, or if Foo is already defined it is appending Bar onto
the end of it. This is *not* what we wanted to have happen here.
Tcl's join function is actually the correct function but its default
joinStr argument is a single space. Unfortunately all of our call
sites do not want an extra space added to their string. So we need
a small wrapper function to make the call to join with an empty
join string. In C this is (roughly) the job of the strcat function.
Since strcat is not yet used at the global level it is a reasonable
name to use here.

Simon Sasburg noticed that on X11 if there are more fonts than can

the tk_optionMenu works properly but is awkward to navigate if the

This is a rewrite of our font selection by providing a new modal

The dialog offers the user a scrolling list of fonts in a pane.
An example text shows the user what the font looks like at the size
they have selected. But I have to admit the example pane is less
than ideal. For example in the case of our diff font we really
should show the user an example diff complete with our native diff
