Shawn O. Pearce 7f09cfafa8 git-gui: Use a smaller pipe buffer for update-index.
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
update followed by lots of waiting between progress updates due to
the latency of update-index.

Using a smaller buffer should help smooth out the progress updates
as we are better able to keep tabs on the update-index process'
progress through our list of paths.

Shawn O. Pearce aaf1085a03 git-gui: Sort the list of paths being updated in the index.
Its a little surprising to see the UI update the icons for files
in random order, due to the fact that the files are updating in
the order they appear within the array (which is based on a hash
function and not order).  So sort the list of files before we send
any to update-index so the order of operation is means something to
the user.

Shawn O. Pearce 358d8de8f3 git-gui: Allow the user to control the number of context lines in a diff.
When displaying a diff the Git default of 3 line of context may not be
enough for a user to see what has actually changed.  Consequently we
set our own program default to 5 lines of context and then allow the
user to adjust this on a per-repository and global level through our
options dialog.

Shawn O. Pearce fd2656fdfe git-gui: Cleanup diff construction code to prepare for more options.
I'd like to allow the user to have more control over how we format
the diff in the diff viewer; to that end we need to add additional
options to the diff-index command line as we construct the command
for execution.

So cleanup the command handling code now to use lappend so we can
come back and add in our additional options.

Shawn O. Pearce 2cbe5577a0 git-gui: Reshow diff if we sent the file to update-index.
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.

Shawn O. Pearce 043f701116 git-gui: Always use eq/ne for string comparsions.
This is one of those stupid Tcl mistakes that an experienced Tcl
programmer just wouldn't make.  We should always use eq and ne to
compare string values (and never == or !=) as when we use ==/!=
Tcl will attempt to convert either side to numeric if one of the
two sides looks like a numeric.  This could cause some trouble if
a file named "1" exists and a different file named "1.0" also exists;
their paths are equal according to == but not according to eq.

We were originally trying to use $commit_active to tell us if there was
a commit currently in progress, just so we didn't attempt to start a
second (parallel) one by mistake.  But really the index lock handles
this for us as it won't let us lock the index if it is already locked
for update.  So this can't happen.

Shawn O. Pearce 4658b56fce git-gui: Run the pre-commit hook in the background.
I started to notice on Windows that commits took a lot longer to get
going than on my Mac OS X system.  The real reason is the repositories
that I'm testing with on Windows all enabled the standard pre-commit hook
while my test repository on Mac OS X doesn't have it executable (so its
not running).  So the Windows repositories are spending this
lag time running that hook.

Now we run the pre-commit hook in the background, allowing the UI to
update and tell the user we are busy doing things.

Shawn O. Pearce ebf336b942 git-gui: Allow the user to disable diff stat summary during pull.
Because the pull diffstat summary can take as long as the pull itself
some users may just choose to disable the summary and save themselves
an extra few seconds during each pull.  This is especially true if the
user really doesn't care about the other files being modified, as due
to their project organizational structure they aren't really responsible
for their content.

This adds an option to the options panel which lets the user disable
the diffstat summary (and thus we pass --no-summary to git-pull) but
there does appear to be a bug in the config saving code where we did
not set the local repo config differently from the global config.

Shawn O. Pearce 6bbd1cb95a git-gui: Don't load the global options unless necessary.
Since git-repo-config will supply us a union of both the global and

there is no reason to go get the global configuration with an extra call
to repo-config unless the user is trying to view & edit all options in

Shawn O. Pearce 7b64d0b7d6 git-gui: Correct bugs in font config handling.
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.

I also found and fixed a bug in the way we restored the fonts when the
user presses Restore Defaults in the options dialog.

Shawn O. Pearce e01b42211c git-gui: Minor options dialog UI cleanups.
Display the name of "this" repository rather than the quite ambiguous
string "This".  The idea is that seeing the name of the directory the
repository is stored in should help jog the user's memory about what
they are setting options for.

Also place the options dialog immediately over the git-gui main window
when it gets opened.  This way the user isn't scrolling very far away
to gain access to the window.  At least on my Mac OS X system not doing
this makes the options dialog open rather far away, thus requiring lots
of mouse activity to reach it.

it won't them do anything else (as the index is locked).

This turned out to take a lot more time than I thought it would take;
but now users can edit the main UI font and the diff/fixed with font
by changing both the family name and/or the point size of the text.

We save the complete Tk font specification to the user's ~/.gitconfig
file upon saving options.  This is probably more verbose than it needs
to be as there are many useless options recorded (e.g. -overstrike 0)
that a user won't really want to use in this application.

Shawn O. Pearce 16fccd7a11 git-gui: Improve right click context menu binding on all platforms.
Apparently <Button-3> doesn't work on my single button PowerBook
mouse under Mac OS X.  I'm guessing this is because Tk is stealing
every event and doesn't realize that Control-Button-1 is actually
supposed to invoke the context menu on this platform.

So now we have a utility procedure is_MacOSX to guess if we are
running on a Mac OS X system, and if so setup Control-Button-1 to
also activate what Button-3 should have.  This does mean that I need
to stay away from using Control-Button-1 as a binding in any other
context.  Of course we should use $M1B for that, which is M1 (aka
Command) on Mac OS X so that shouldn't prove to be a problem.

The native Tk font system is actually quite powerful and has the nice
property that modifications to a named font are immediately reflected
throughout all widgets currently displayed.  This really saves us
from needing to write all of the reconfigure code as part of our font
display.

UI widgets as although it worked on a Windows 2000 system it does not
work at all on my Mac OS 10.4 system.

Shawn O. Pearce 16403d0b1f git-gui: Refresh a file if it has an empty diff.
When the user has enabled the Trust File Modification Timestamp option
then we may display a file as being modified yet that file may not have
a difference.  When the user clicks on that file we wind up displaying
an empty diff viewer, which makes no sense to the user.

So instead if we get an empty diff and the user has this option enabled
and the file's current state is _M (no change in index but the working
file appears modified) then run a quick update-index on just that file
and remove it from the list of modified files.  We also give the user
a quick dialog stating we are removing it, and why.

Usually I don't run into this situation when I have the Trust File
Modification Timestamp option enabled, so its not that annoying to
have a dialog pop open to remind me why there are no differences.

Because the diff area is one of the most important areas to be able to
read users should be able to increase or decrease the size of the font
used within that area.

Currently we save that back to the global configuration, even if it
may have originated from the local repository configuration.  This
is probably going to be considered to be a bug by at least one user
who wants some sort of different font within a given repository, but

So now we always set the cursor to left_ptr (which according to the Tk

areas which we use to list file names, as the user clicks in these but
is not permitted to select text.

When we commit we know that whatever was in the index went as part

update the index except through our user interface we can be reasonably
certain that any file which was marked as A/M/D in the index will have
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
by simply updating the index part of the file state of all files whose
index state was A/M/D to _ and then removing any file memory any which
wound up with a final state of __ (not different anywhere).  Finally we

When we did a rescan to update the file lists we lost the tag which
indicated which file was currently in the diff viewer.  This occurs
because we delete every line from the two file list boxes (thus
removing the tag) and then redisplay the diff in the diff viewer
but then fail to restore the tag in the file list.

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
given a file name which contains an LF within it (as that would span
two lines in the file list, not one).

If we load a message file (e.g. MERGE_MSG) or we have just finished

is not useful to the user.

Also modified the sign-off operation to perform the entire update in
a single undo/redo operation, allowing the user to undo the signoff
in case they didn't actually want to do that.

I also noticed what may be a crash on Windows related to the up and
down arrow keys navigating within the diff viewer.  Since I got back
no stack trace (just an application exit with a loss of the commit
message) I suspect that the binding to scroll the text widget crashed
with an error and the wish process just terminated.  So now we catch
(and ignore) any sort of error related to the arrow keys in the diff
viewer.

There's really no great reason to show the entire commit object id
within the GUI, especially if the user is unable to copy and paste
it into another interface such as gitk or a terminal window.  So
we'll just show them the first 8 digits and hope that is unique

Shawn O. Pearce 7fe7e733fa git-gui: Changed term 'check-in' to 'include'.
At least one user was confused by the term 'check-in'; he thought that
clicking that button would commit just that one file, but he wanted to
include all modified files into his next commit.

Since git doesn't really have a check-in concept this really was poor
language to use.  Git does have an update-index concept but that is a
little too low level to show to the user.

So instead we now talk about including files in a commit.

Shawn O. Pearce ec39d83a55 git-gui: Don't let the user pull into an uncommitted working directory.
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.

Shawn O. Pearce 988b8a7d63 git-gui: Grab the index lock while running pull.
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.

Shawn O. Pearce e534f3a886 git-gui: Allow the user to disable update-index --refresh during rescan.
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.

Shawn O. Pearce d1536c488e git-gui: Added repack database menu option, to invoke git repack.
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.

Shawn O. Pearce 0fb8f9ce05 git-gui: Flip commit message buffer and diff area.
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.

Shawn O. Pearce 6b29267542 git-gui: More performance improvements to rescan logic.
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.

Shawn O. Pearce 93f654df7e git-gui: Performance improvements for large file sets.
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.

Shawn O. Pearce 868c875245 git-gui: Corrected diff-index/diff-files protocol parsing errors.
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).

Shawn O. Pearce cc4b1c0213 git-gui: Worked around environment variable problems on Windows.
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.
