75e355d6be git-gui: Seperate out the database operations in project menu.
The project menu is just too cluttered without using separator entries
to split out the database operations (such as repack and verify) from
the other options in the same menu.

93a7991205 git-gui: Reworded verify console title.
It would be something of a disservice to our users if we refer to
fsck-objects as "verify".  So instead we call it fsck-objects in
the console title, and indicate that's how we are verifying the
object database.

We probably should call our menu option "fsck-objects" or similar
but I really do think that "Verify Database" more accurately describes
the action then "fsck-objects" does, especially to users who aren't
file system developers.

Because we don't automatically restart in amend mode when we quit while
in amend mode the commit message buffer shouldn't be saved to GITGUI_MSG

444f92d097 git-gui: Allow users to run fsck-objects from the gui.
I recently found a need to run fsck-objects in a number of repositories
that I also use git-gui against.  Tossing in a menu option to invoke
fsck-objects and have its output show up in a console window is simple
enough to do.

We probably need to enhance the console window used by fsck-objects,
like to open up the Git fsck-objects manual page and let the user see
what each message means (such as "dangling commit") and to also let the
user invoke prune, to cleanup any such dangling objects.  But right now
I'm going to ignore that problem in favor of getting other more important
features implemented.

f18e40a1a6 git-gui: Improve handling of merge commits.
Its useful to be able to amend the last commit even if it was a merge
commit, so we really should support that in the gui.  We now do so by
making PARENT a list.  We always diff against the first parent but we
create a commit consisting of the parent(s) listed in this list, in
order.

We also should recheck the repository state during an amend.  Earlier
I was bitten by this exact bug when I switched branches through a
command prompt and then did not do a rescan in git-gui.  When I hit
"Amend Last Commit" I was surprised to see information from the prior
branch appear.  This was due to git-gui caching the data from the last
rescan and using that data form the amend data load request, rather than
the data of the current branch.

Improved error text in the dialogs used to tell the user why an amend is
being refused by git-gui.  In general this is only during an initial
commit (nothing prior to amend) and during a merge commit (it is simply
too confusing to amend the last commit while also trying to complete a
merge).

Fixed a couple of minor bugs in the pull logic.  Since this code isn't
really useful nobody has recently tested it and noticed the breakage.
It really needs to be rewritten anyway.

a29481e212 git-gui: Update in memory states after commit.
In order to allow the user to toggle include/exclude from next commit
for files which were partially included in the last commit we need the
current index mode+sha1 data stored in our file_states array.  For
any partially included file we have this information from diff-files,
so we just have to copy it over to the diff-index portion of our state
array.

38dbe273ff git-gui: Refactored diff line display formatting logic.
The tags used for diff formatting (which I inherited from gitool) just
didn't make a whole lot of sense, especially if you wanted to try to
match them to the diff output you were seeing on screen.  It did not
help that the diff-index -c output's first two columns are also munged
to make the diff output more user friendly.

So this is a large refactoring of the tags used for diff display.  Now
our tag names match what we put in the left column of each line, which
makes it easier to correlate presentation and implementation.

I removed bold font usage from everything except the hunk headers as I
really did not like the way bold font caused column alignments to become
out of whack within the diff viewer.  It also drew attention to the parts
of the file which were identically changed in both the index and in the
working directory, yet these are usually the parts I find myself caring
the least about.  So its very counter-intuitive.

Lines which are changed differently by both the index and the working
directory are now shown with background colors which span the entire line,
making these lines easier to pick out of the diff.  In general these are
the lines that appear to be more interesting to me when looking at the
3-way diff as they are the ones which contain recent and quite different
changes.

51cc47feda git-gui: Correct toggling of added/untracked status for new files.
New files also lack index data from diff-files therefore we cannot use
their diff-files index data when we update-index.  Instead we can use
the fact that Git has them hardcoded as "0 0{40}" and do the same thing
ourselves.  This way you can toggle an untracked file into added status
and back out to untracked.

0d5709cf88 git-gui: Describe deleted symlinks in a more friendly way.
Currently core-git's diff utilities report a deleted symlink as a
deleted file with a mode of 120000.  This is not nearly as user
friendly as one might like, as the user must remember that 120000
is the UNIX mode bits for a symlink.  So instead we transform
the not-so-friendly message from core-git into a slightly more
user friendly "deleted symlink" message.

Tcl let me assign two different types of values to the variable $n.
Prior to 1461c5f3 $n was the total number of bytes in the string;
but in that commit it also became the current info list for the

The previous implementation of do_include_selection did not actually
add files in state _O (untracked, not added) into the repository when
they were in the selection and Commit->Include Selected Files was used.

bca680b054 git-gui: Rephrase rescan before commit informational message.
Its not an error that a rescan is required before commit; its just
something we do as a safety feature to try and ensure the user knows
what is going into this commit.  So the dialog should use the info
icon (if one is used by the host OS) rather than the error icon.

Its also not "highly likely" that another Git program modified the
repository, its completely the case.  There is no reason why the
repository would not match our last scanned state unless another
Git program modified the repository (or someone else did so by hand).
So don't be vague about it, own up to the issue and go on with our
business.

53716a7bc9 git-gui: Start UI with the index locked.
Because we immediately start a rescan operation, but do so slightly
delayed (by 1 ms, to let the UI show before we start forking off
git processes), we can't let the user try to activate any of the
restricted GUI commands before the 1 ms timer expires and we kick
off the rescan.

So now we lock the index before we enter the Tk event loop, ensuring
that it is impossible for the user to inject a conflicting UI event
before our rescan can begin.

c4ed879fc2 git-gui: Add menu option to include only selected files.
When the user selects a number of files they would typically expect
to be able to act on that selection, such as by including those files
into the next commit.

So we now have a menu option under the Commit menu that lets the user
include only the selection, rather than everything.  If there is no
selection but there is a file in the diff viewer than we consider that
to be the selection (a selection of 1).  Unfortunately we don't disable
this option yet when there's nothing selected to include, but this is
probably not a big deal as there are very few situations where there
are no selected files.

32e0bcab59 git-gui: Only reshow diff when really necessary.
I noticed that we were reshowing the current diff during a commit;
this occurs because we feed every added and modified file through
update-index just before commit.  During the update-index process
we reshow the current diff if the current file in the diff pane
was one of those added or modified files we reprocessed.  This
just slows down the UI more than is necessary.

4539eacd6d git-gui: Make initial commits work properly.
Apparently I never really tested the logic for making or amending an
initial commit, so although most of the code was here in git-gui it
didn't quite work as it was intended to.

So this is all just bug fixes to make initial commits correctly
generate the list of files going into the initial commit, or to
show a newly added file's diff, and to amend an initial commit.

Because we really want to diff the index against a tree-ish and
there is no such tree-ish on an initial commit we create an empty
tree through git-mktree and diff against that.  This unfortunately
creates a dangling tree, which may confuse a new user who uses
git-gui to make a new commit and then immediately afterwards runs
git fsck-objects to see if their object database is corrupt or not.

24263b7716 git-gui: Implemented multiple selection in file lists.
Because I want to let users apply actions to more than one file at
a time we really needed a concept of "the current selection" from
the two file lists.

Since I'm abusing a Tk text widget for the file displays I can't
really use the Tk selection to track which files are picked and
which aren't.  So instead we keep this in an array to tell us
which paths are currently selected and we use an inverse fg/bg
for the selected file display.  This is common most operating
systems as a selection indicator.

The selection works like most users would expect; single click will
clear the selection and pick only that file, M1-click (aka Ctrl-click
or Cmd-click) will toggle the one file in/out of the selection, and
Shift-click will select the range between the last clicked file and
the currently clicked file.

f7f8d32226 git-gui: By default don't allow partially included files.
The concept of the Git index is confusing for many users, especially
those who are newer to Git.

Since git-gui is (at least partially) intended to be used by newer
users who don't need the complexity of the index to be put in front
of them early on, we should hide it by making any partially included
file fully included as soon as we identify it.  To do this we just
run a quick update_index pass on any file which differs both in the
index and the working directory, as these files have already been
at least partially included by the user.

A new option has been added in the options dialog (gui.partialinclude)
which lets the user enable accessing the index from git-gui.  This
just disables the automatic update_index pass on partially included
files.

fce89e466a git-gui: Reverted file name text field to a label.
So although a text field with a flat relief looks like a label on
Windows it doesn't on Mac OS X.  The Aqua version of Tk is still
drawing a border around the text field and that makes the diff pane
header look pretty ugly.

Earlier I had made the file name area into a text widget so the user
could highlight parts of it and copy them onto the clipboard; but with
the context menu being present this isn't quite as necessary as the user
can copy the file name to the clipboard using that instead.  So although
this is a small loss in functionality for non-Mac OS X systems I think it
is still reasonable.

1e5c18fb43 git-gui: Minor UI layout improvements for console windows.
Moved the Close button over to the lower right corner where our
Cancel/Save buttons are in the options dialog.  This should fit
better with our own look and feel as well as that of most apps
on Mac OS X and Windows.

Also set the lower status bar in a console window to indicate the
process is working and that the user should wait for it to finish.

3e7b0e1d0a git-gui: Display status on left in diff header.
Because the Tk pack layout manager gives all space to the right/bottom
most widget during expand/contract of the frame we were adding and
removing all space from the status area of the bar and not from the
file name, which is what we actually wanted.

A simple enough fix is to just put the status of the given file on
the left side of the diff viewer header rather than on the right.

135f76ed99 git-gui: Correct language for M_/A_ status codes.
When I changed from 'check in' to 'include' I missed the human friendly
status displayed in the right side of the diff viewer heading.  It was
still reporting 'Checked in' for a fully included file, which is not
what we wanted it to say.

c11b5f20d3 git-gui: Allow the user to copy name of the file in the diff viewer.
There's a lot of reasons why the user might need to obtain the
complete (or just part of) path of a file which they are currently
viewing in the diff viewer pane.  So now we allow selection on this
widget by using a text widget instead of a label.  We also offer a
context menu which has actions for copying the selection or the entire
value onto the clipboard.
