I just found a whole slew of places where we still were using the term

There appears to be a bug on one of my test systems where cygpath with
the --long-name option is generating a corrupt string that does not
actually refer to sh.exe. This breaks any desktop icon created by
git-gui as the executable we are trying to invoke does not exist.
Since Cygwin is typically installed as C:\cygwin long path names is
probably not actually necessary to link to the shell.
I also added a small echo to the start of the icon script, as it can
take one of my test systems several seconds to startup git-gui. This
way the user knows we're starting git-gui, and was politely asked to
wait for the action to complete.

We no longer describe updating the index as including changes, as we

Apparently I did not account for the D_ file state. This can occur when
a file has been marked for deletion by deleting it from the index, and
the file also does not exist in the working directory. Typically this
happens when the user deletes the file, hits Rescan, then includes the
missing file in the commit, then hits Rescan again. We don't find the
file in the working directory but its been removed in the index, so the
state becomes D_.
This state should be identical with DD. I'm not entirely sure why DD
occurs sometimes and D_ others, it would seem like D_ is the state that
should be happening instead of DD, leading me to believe there is a quirk
in git-gui's state manipulation code.

Now that git 1.5.0-rc1 and later has a 'git gc' command which performs
all important repository management activites (including reflog pruning,
repacking local objects, unnecessary loose object pruning and rerere cache
expiration) we should run 'gc' when the user wants us to cleanup their
object database for them.
I think the name 'gc' is horrible for a GUI application like git-gui,
so I'm labeling the menu action 'Compress Database' instead. Hopefully
this will provide some clue to the user about what the action does.

If the user has partial includes disabled then it doesn't matter what

correct, and that they didn't just include the file into the commit

Sometimes its useful to start gitk with the --all option, to view all of

This also makes it slightly more explicit, that when gitk starts up by
default its showing the current branch and not everything. Yes gitk
isn't showing that to the user, but the fact that the user had to make
a decision between seeing this current branch or all branches will
hopefully make them study gitk's display before jumping to a conclusion.

Because the Tcl binary distributed with Cygwin tends to not pass along
its own environment (the env array) to its children, its unlikely that
any Git commands spawned by git-gui will receive the same environment
variables that git-gui itself received from the shell which started it.
If the user is counting on environment variables to pass down, like say
GIT_INDEX_FILE, they may not, so we warn them during git-gui startup
that things may not work out as the user intended. Perhaps one day
when git-gui and git are running on native Windows (rather than through
the Cygwin emulation layers) things will work better.

I recently found a need to run fsck-objects in a number of repositories

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

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.

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.

New files also lack index data from diff-files therefore we cannot use

Its not an error that a rescan is required before commit; its just

Its also not "highly likely" that another Git program modified the
repository, its completely the case. There is no reason why the

Because we immediately start a rescan operation, but do so slightly

When the user selects a number of files they would typically expect

selection but there is a file in the diff viewer than we consider that

Apparently I never really tested the logic for making or amending an

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

Mac OS X by creating a .app file with a tiny shell script in it that
sets up the necessary environment then invokes our script.

If we are running on Windows we now offer a 'Create Desktop Icon' menu
item under the Project menu. This pops up a save dialog box letting
the user create a .bat file on their desktop (or somewhere else). The

in the current working directory.
This is very useful for Windows users who have little to no desire to

Some users may want to start us by running "git --git-dir=... gui"
rather than trying to cd into the directory first. This is especially
true if they want to just make a shortcut to our executable on Windows
and always have that associated with a certain repository.
Since Tcl on Windows throws away our environment and doesn't pass it
down to the child process correctly we cannot call git-rev-parse to
get the GIT_DIR environment variable. So instead we ask for it
specifically ourselves; if its not defined then we ask rev-parse.
This should actually reduce startup by 1 fork/exec if we were started
as "git gui" as GIT_DIR will be set for us.

There is no reason why the user should be able to operate on the diff
buffer if there is no currently selected diff; likewise the "File:"

currently showing, and we disable them when a diff isn't showing.

If the user has "Allow Partially Included Files" disabled (and most
probably will as its the default setting) we should run update-index
on every included file before commit to make sure that any changes
made by the user since the last rescan will still be part of this
commit.
If we don't update-index every modified file the user will likely
become confused when part of their changes were committed and other
parts weren't; and those other parts won't show up until a later
rescan occurs. Since we don't rescan immediately after a commit
this may be a while.
Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
Like rescan we also have cases where we need to perform a script
after we have finished updating a number of files in the index. By
changing the parameter structure of update_index we can easily pass
through any script we need to run afterwards, such as picking up
in the middle of a commit, or finishing what is left of a rescan.
Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
There are some situations where we need to run rescan and have it do
more than just updating the status in the UI when its complete. To
help with that this changes the rescan procedure to take a script which
it will run at the global level as soon as the rescan is done and the
UI has finished updating with the results. This is useful for example
if we performed a rescan as part of a commit operation; we can go back
to the commit where we left off when the rescan got initiated.

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.

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.

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.

When we shove a large number of files at update-index and they have
very short path names we are likely going to fit a large number of

We can't ask the diff viewer to recompute the diff until after our
update-index child process terminates, as the diff programs need to
be able to read the updated index in order to generate the correct
diff. This is actually why we prevent diffs from being generated
while there is an update lock on the index, which is why we ignored
our own show_diff invocation in the middle of the write_update_index
event handler.
So now we mark a flag if we identify that the file currently in the
diff viewer was also sent to update-index; then later when the
update-index process has terminated we update the diff viewer if
the flag is true.

This adds an option to the options panel which lets the user disable

Apparently Tcl is being helpful on Windows during exec and is throwing a
\ in front of every { it finds in the string. I'm guessing they think
the value might be read by another Tcl program? Anyway, Git faithfully
stores the \{ sequence and sends it back that way to Tcl, at which point
Tcl parses the list wrong and starts to break it in the middle of any
element which contains spaces. Therefore a list such as:
-family {Times New Roman}
gets broken up into the pairs:
{-family \{Times}
{New Roman}
which is very incorrect. So now we replace all { and } with "", at which
point Tcl doesn't throw \ in front of the " on the way out to Git yet it
reads it correctly as a list on the way back in.

When the user has enabled the Trust File Modification Timestamp option

had that A/M/D state changed to an _ (not different) by the commit.
We can use this knowledge to update the user interface post commit

Now we restore that tag by searching for the file in the file lists
and adding the tag back when the diff viewer displays something.
We also no longer obtain the file path directly from the file list
text box. Instead we now keep two Tcl lists, one for each file list,
holding the file names in sorted order. These lists can be searched
with the native [lsearch -sorted] operation (which should be faster
than our crude bsearch) or can be quickly accessed by index to return
the file path. This should help make things safer should we ever be

When a file jumps between the file lists due to its state changing we
crashed thanks to a stale variable reference within the procedure as we
tried to setup the new icon.

If there are modified files present in the working directory then we
should not let the user perform a pull as it may fail due to the modified
files being uncommitted but needing to be merged at the file level.
Yes there are many cases where a merge will complete successfully even
though there are modified or untracked files sitting in the working
directory. But users generally shouldn't be attempting merges like that,
and if they are they probably are advanced enough to just use the command
line and bypass this little safety check.
We also no longer run a rescan after a successful pull has completed.
Usually this is unnecessary as a successful pull won't leave modified
files laying around. Instead we just update our HEAD and PARENT values
with the new commit, if there is one.
Unfortunately this does let the user get into an insane state as there
are bugs in core Git's git-pull and git-merge programs where the exit
status is sent back as a 0 rather than non-0 when a failure is detected.

If we have the index locked then no pull command is allowed to proceed
(as it would fail to get the index lock itself). So disable the pull
menu items when we are doing any index based operations.
