If a user works with a repository frequently they may want to just
create an icon they can use to launch git-gui against that repository.
Since we already support this concept on Windows we can do the same on
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.

Since we have some serious problems with the GIT_DIR environment variable

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
.bat script will startup Cygwin with a login shell then launch git-gui
in the current working directory.
This is very useful for Windows users who have little to no desire to
start a command window just to run a git-gui session.

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
them into the pipe buffer very early; thereby seeing a huge progress

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

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.
Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
The user must not modify the index while a git pull operation is running,
doing so might cause problems for the merge driver and specific strategy
being used. Normally on the command line people are just really good and
don't try to run index altering operations while they are also running a
pull. But in a slick GUI like git-gui we can't trust the user quite as
much.

On very large projects (~1000 files) on Windows systems the update-index
--refresh stage of the rescan process takes a nontrival amount of time.
If the user is generally very careful with their file modification such
that the modification timestamp of the file differs only when the content
also differs then we can skip this somewhat expensive step and go right
to the diff-index and diff-files processes.
We save the user's prefernce in the current repository if they modify the
setting during a git-gui session, but we also load it through our dump of
repo-config --list so the user could move it to their ~/.gitconfig file
if they wanted it globally disabled.
We still keep update-index --refresh enabled by default however, as most
users will probably want it.

Most users of git-gui probably shouldn't be invoking git repack directly;
instead we should be looking at how many loose objects they have and
how many active packs they have and making the decision for them. But
that's more work to code, and there's always going to be discussion about
what is the right default threshold and how do we know that the user is
willing to do the repack when we decide its time, etc.
So instead we'll just keep it simple and offer up the menu option.
Unfortunately right now we get now progress indication back from
git-pack-objects as its being invoked not through a tty, which makes
it disable progress output and the git-repack.sh wrapper won't let us
pass through --progress.

Since Tk will only supply new space gained from growing the top level to
the bottom/right most widget within a panedwindow and most users will be
growing a git-gui main window for the purposes of seeing more of the
currently shown diff, flipping the order around makes Tk do what the
user wants by default.
Of course because we also removed the paned window from the commit buffer
area it is now impossible to increase the visible space for the commit
message. But I don't see this as a huge concern right now as its actually
very awkward to try and balance three paned window dividers within the
same top level window. We could always add it back if users really want
to expand the commit buffer and see more.
I also corrected a number of bugs that I accidentally introduced in the
last commit.

Removed as much as possible from the merge_state proc, which is where
we spent most of our time before UI update. This change makes our
running time match that of git status, except that we then need about
7 additional seconds to draw 6900 files on screen.
Apparently the [array names a -exact $v] operator in Tcl is O(n) rather
than O(1), which is really quite disappointing given that each array can
only have one entry for a given value. Switching to a lookup with a
catch (whose error we ignore) runs in O(1) time and bought us most of
that improvement.
Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
Loading 6900 newly added files required about 90 seconds on one system.
This is just far too long to perform a "status" type of operation.
git-status on the same system completes in just 8.2 seconds if it is
redirected to /dev/null.
Most of our performance improvement comes from moving all of the UI
updating out of the main fileevent handlers for the status process.
Instead we are only updating the file_states array and then only doing
the UI update when all states are known and have been finally determined.
The rescan execution is now down to almost 30 seconds for the same case,
a good (but not really all that impressive) improvement.

When we were receiving a lot of output from diff-index we split records
at the wrong locations and started using the file status information
(mode and SHA1s) as path names, and then proceeded to try to use part
of the path names as status data. This caused all sorts of havoc.
So I rewrote the parsing implementation to scan for the pair of null
bytes along the buffer and stop scanning (waiting for more data) if
both can't be found during this event. This seems to work well under
high load (like when processing 6,983 added files).

We now create one menu entry per remote listing the first Pull: or fetch
entry associated with that remote as the branch to pull into the current
branch.
This is actually quite incorrect as we should be using the default
remote branch name listed in branch.<name>.merge for a new-style remote
described in the config file. But its a good default to get started with.

We're likely going to need key/value pairs from the repo-config beyond
just remote.*.url, so cache them all up front into a Tcl array where we

If the user closes a console and we get more ouptut for it then we
will get a Tcl error in the readable event handle for the file channel.
Since this loses the actual output and is quite unfriendly to the end
user instead reopen any console which the user closed prior to the
additional output arriving.

Because the remote end is likely to send us progress meters by
resetting each line with a CR (and no LF) we should display those
meters by replacing the last line of text with the next line,
just like a normal xterm would do.
This makes the output of fetch look about the same as if we ran it
from within an xterm.

Because we cd after getting the cdup value from Git we can't try

Apparently the Cygwin tclsh/wish executables don't pass the environment
that they inherited onto any children that they invoke. This causes a
problem for some users during 'git fetch' or 'git push' as critical
environment variables like GIT_SSH and SSH_AUTH_SOCK aren't available
to the git processes.
So we work around this by forcing sh to start a login shell, thus
reloading the user's environment, then cd to the current directory,
and finally start the requested process. Of course this won't
correctly handle any transient environment variables that were
inherited but were not supplied by the user's login shell.

This is based on Paul Mackerras' gitool prototype which he offered up
to the community earlier in 2006. Its mostly however a rewrite from

Currently it can display the status of the current repository, and not
