If the user is in the middle of a commit they have files which are
modified. These may conflict with any merge that they may want
to perform, which would cause problems if the user wants to abort
a bad merge as we wouldn't have a checkpoint to roll back onto.

If an octopus merge goes horribly wrong git-merge will leave the
working directory and index dirty, but will not leave behind a
MERGE_HEAD file for a later commit. Consequently we won't know
its a merge commit and instead would let the user resolve the
conflicts and commit a single-parent commit, which is wrong.
So now if an octopus merge fails we notify the user that the
merge did not work, tell them we will reset the working directory,
and suggest that they merge one branch at a time. This prevents
the user from committing a bad octopus merge.

If you get into the middle of a merge that turns out to be horrible
and just not something you want to do right now, odds are you need
to run `git reset --hard` to recover your working directory to a

We now offer Merge->Abort Merge for exactly this purpose, however
its also useful to thow away a non-merge, as its basically the same
logic as `git reset --hard`.

To allow users to merge local heads and tracking branches we now offer
a dialog which lets the user select 1-15 branches and merge them using
the stock `git merge` Grand Unified Merge Driver.
Originally I had wanted to implement this merge internally within git-gui
as I consider GUMD to be mostly Porcelain-ish, but the truth is it does
its job exceedingly well and its a relatively complex chunk of code.
I'll probably circle back later and try to remove the invocation of GUMD
from git-gui, but right now it lets me get the job done faster.
Users cannot start a merge if they are currently in the middle of one,
or if they are amending a commit. Trying to do either is just stupid
and should be stopped as early as possible.
I've also made it simple for users to startup a gitk session prior to
a merge by offering a Visualize button which runs `gitk $revs --not HEAD`,
where $revs is the list of branches currently selected in the merge
dialog. This makes it quite simple to find out what the damage will
be to the current branch if you were to carry out the currently proposed
merge.

Technically the new git-gc command is strictly Porcelain; its invoking
multiple plumbing commands to do its work. Since git-gui tries to not
rely on Porclain we shouldn't be invoking git-gc directly, instead we
should perform its tasks on our own.
To make this easy I've created console_chain, which takes a list of
tasks to perform and runs them all in the same console window. If
any individual task fails then the chain stops running and the window
shows a failure bar. Only once all tasks have been completed will it
invoke console_done with a successful status.

Because I want to be able to run multiple output-producing commands
in a single 'console' window within git-gui I'm refactoring the
console handling routines to require the "after" argument of console_exec.
This should specify a procedure to execute which will receive two args,
the first is the console window handle and the second is the status of
the last command (0 on failure, 1 on success).
A new procedure console_done can be passed to the last console_exec
command to forward perform all cleanup and enable the Close button.
Its status argument is used to update the final status bar on the
bottom of the console window.
This isn't any real logic changing, and no new functionality is in
this patch.

Right now `git-push -v` is actually not that verbose; it merely adds

We now provide a basic 'Push...' menu action in the Push menu which

which repository to send the changes to by selecting from an already

I just noticed that a file was always jumping to compare against HEAD
and the index during a refresh, even if the diff viewer was comparing
the index against the working directory prior to the refresh. The
bug turned out to be caused by a foreach loop going through all file

searched and the file was contained in that file list the loop broke
out, leaving $w set to $ui_index when it had been set by the caller
to $ui_workdir. Silly bug caused by using a parameter as a loop

The Pull menu as it stands right now is a really horrible idea. Most

merging that just isn't really valid. So this menu is dead and will
be rewritten to support better merge capabilities.
The Branch menu shouldn't include a separator entry if there are no

Apparently a "feature" of Tcl/Tk on Mac OS X is that a disabled text

When committing changes its useless to have trailing whitespace on the
end of a line within the commit message itself; this serves no purpose
beyond wasting space in the repository. But it happens a lot on my
Mac OS X system if I copy text out of a Terminal.app window and paste
it into git-gui.
We now clip any trailing whitespace from the commit buffer when loading
it from a file, when saving it out to our backup file, or when making
the actual commit object.
I also fixed a bug where we lost the commit message buffer if you quit
without editing the text region. This can happen if you quit and restart
git-gui frequently in the middle of an editing session.

If we are displaying a diff for a DOS-style (CRLF) formatted file then
the Tk text widget would normally show the CR at the end of every line;
in most fonts this will come out as a square box. Rather than showing
this character we'll tag it with a tag which forces the character to
be elided away, so its not displayed. However since the character is
still within the text buffer we can still obtain it and supply it over
to `git apply` when staging or unstaging an individual hunk, ensuring
that the file contents is always fully preserved as-is.
Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
Just like `git-add --interactive` we can now stage and unstage individual
hunks within a file, rather than the entire file at once. This works
on the basic idea of scanning backwards from the mouse position to
find the hunk header, then going forwards to find the end of the hunk.
Everything in that is sent to `git apply --cached`, prefixed by the
diff header lines.
We ignore whitespace errors while applying a hunk, as we expect the
user's pre-commit hook to catch any possible problems. This matches
our existing behavior with regards to adding an entire file with
no whitespace error checking.
Applying hunks means that we now have to capture and save the diff header
lines, rather than chucking them. Not really a big deal, we just needed
a new global to hang onto that current header information. We probably
could have recreated it on demand during apply_hunk but that would mean
we need to implement all of the funny rules about how to encode weird
path names (e.g. ones containing LF) into a diff header so that the
`git apply` process would understand what we are asking it to do. Much
simpler to just store this small amount of data in a global and replay
it when needed.
I'm making absolutely no attempt to correct the line numbers on the
remaining hunk headers after one hunk has been applied. This may
cause some hunks to fail, as the position information would not be
correct. Users can always refresh the current diff before applying a
failing hunk to work around the issue. Perhaps if we ever implement
hunk splitting we could also fix the remaining hunk headers.
Applying hunks directly means that we need to process the diff data in
binary, rather than using the system encoding and an automatic linefeed
translation. This ensures that CRLF formatted files will be able to be
fed directly to `git apply` without failures. Unfortunately it also means
we will see CRs show up in the GUI as ugly little boxes at the end of
each line in a CRLF file.

If the user selects a different branch from the Branch menu, or asks
us to create a new branch and immediately checkout that branch we
now perform the update of the working directory by way of a 2 way
read-tree invocation.
This emulates the behavior of `git checkout branch` or the behavior
of `git checkout -b branch initrev`. We don't however support the
-m style behavior, where a switch can occur with file level merging
performed by merge-recursive. Support for this is planned for a

Its nice to know how many loose objects and roughly how much disk space
they are taking up, so that you can guestimate about when might be a
good time to run 'Compress Database'. The same is true of packfiles,
especially once the automatic keep-pack code in git-fetch starts to
be more widely used.
We now offer the output of count-objects -v in a nice little dialog
hung off the Repository menu. Our labels are slightly more verbose
than those of `count-objects -v`, so users will hopefully be able
to make better sense of what we are showing them here.
We probably should also offer pack file size information, and data
about *.idx files which exist which lack corresponding *.pack files
(a situation caused by the HTTP fetch client). But in the latter
case we should only offer the data once we have way to let the user

Git prefers that all log messages are encoding in UTF-8. So now when
git-gui generates the commit message it converts the commit message
text from the internal Tcl Unicode representation into a UTF-8 file.
The file is then fed as stdin to git-commit-tree. I had to start
using a file here rather than feeding the message in with << as
<< uses the system encoding, which we may not want.
When we reload a commit message via git-cat-file we are getting the
raw byte stream, with no encoding performed by Git itself. So unless
the new 'encoding' header appears in the message we should probably
assume it is utf-8 encoded; but if the header is present we need to
use whatever it claims.

Since git operates on filenames using the operating system encoding

Our internal diff viewer displays untracked files to help users see if
they should become tracked, or not. It is not meant as a full file
viewer that handles any sort of input. Consequently it is rather
unreasonable for users to expect us to show them very large files.
Some users may click on a very big file (and not know its very big)
then get surprised when Tk takes a long time to load the content and
render it, especially if their memory is tight and their OS starts to
swap processes out.
Instead we now limit the amount of data we load to the first 128 KiB
of any untracked file. If the file is larger than 128 KiB we display
a warning message at the top of our diff viewer to notify the user
that we are not going to load the entire thing. Users should be able
to recognize a file just by its first 128 KiB and determine if it
should be added to the repository or not.
Since we are loading 128 KiB we may as well scan it to see if the
file is binary. So I've removed the "first 8000 bytes" rule and
just allowed git-gui to scan the entire data chunk that it read in.
This is probably faster anyway if Tcl's [string range] command winds
up making a copy of the data.

A binary file can be very large, and showing the complete content of
one is horribly ugly and confusing. So we now use the same rule that
core Git uses; if there is a NUL byte (\0) within the first 8000 bytes
of the file we assume it is binary and refuse to show the content.
Given that we have loaded the entire content of the file into memory
we probably could just afford to search the whole thing, but we also
probably should not load multi-megabyte binary files either.

If we got an empty diff its probably because the modification time of
the file was changed but the file content hasn't been changed. Typically
this happens because an outside program modified the file and git-gui
was told to not run 'update-index --refresh', as the user generally
trusts file modification timestamps. But we can also get an empty diff
when a program undos a file change and still updates the modification
timestamp upon saving, but has undone the file back to the same as what
is in the index or in PARENT.
So even if gui.trustmtime is false we should still run a rescan on
an empty diff. This change also lets us cleanup the dialog message
that we show when this case occurs, as its no longer got anything to
do with Trust File Modification Timestamps.

Unfortunately this meant that I needed to change the background colors

hunks which came from HEAD/parent^1, which are the portions that the
current branch has contributed, and are probably the user's own changes.
We use a very light blue for the portions which came from FETCH_HEAD,
as this makes the changes made by the other branch stand out more in the
diff.
I've also modified the hunk header lines to be blue, as that is how gitk

Apparently I forgot to raise the sel tag above everything else in the

understand the particular state of any given line. This way we know
if we aren't tagging something we maybe should have tagged in the UI.
I've also added special display of the standard conflict hunk markers
(<<<<<<<, =======, >>>>>>>). These are formatted without a patch op
as the patch op is always '+' or '++' (meaning the line has been added
relative to the committed state) and are displayed in orange bold text,
sort of like the @@ or @@@ marker line is at the start of each hunk.
In a 3 way merge diff hunks which came from our HEAD are shown with a
azure2 background, and hunks which came from the incoming MERGE_HEAD
are displayed with a 'light goldenrod yellow' background. This makes
the two different hunks clearly visible within the file. Hunks which
are ++ or -- (added or deleted relative to both parents) are shown
without any background at all.

If a file has a merge conflict we want it to show up in the 'Changed
But Not Updated' file list rather than the 'Changes To Be Committed'
file list. This way the user can mostly ignore the left side (the
HEAD<->index comparsion) while resolving a merge and instead focus
on the merge conflicts, which are just shown on the right hand side.
This requires detecting the U state in the index side and drawing
it as though it were _, then forcing the working directory side to
have a U state. We have to delay this until presentation time as
we don't want to change our internal state data to be different
from what Git is telling us (I tried, the patch for that was ugly
and didn't work).
When showing a working directory diff and its a merge conflict we
don't want to use diff-files as this would wind up showing any
automatically merged hunks obtained from MERGE_HEAD in the diff.
These are not usually very interesting as they were completed by
the system. Instead we just want to see the conflicts. Fortunately
the diff porcelain-ish frontend (aka 'git diff') detects the case of
an unmerged file and generates a --cc diff against HEAD and MERGE_HEAD.
So we now force any working directory diff with an index state of 'U'
to go through that difference path.

The combined diff format can be very confusing, especially to new users
who may not even be familiar with a standard two way diff format. So
for files which are already staged for commit and which are modifed in
the working directory we should show two different diffs, depending on
which side the user clicked on.
If the user clicks on the "Changes To Be Committed" side then we should
show them the PARENT<->index difference. This is the set of changes they
will actually commit.
If the user clicks on the "Changed But Not Updated" side we should show
them the index<->working directory difference. This is the set of changes
which will not be committed, as they have not been staged into the index.
This is especially useful when merging, as the "Changed But Not Updated"
files are the ones that need merge conflict resolution, and the diff here
is the conflict hunks and/or any evil merge created by the user.

We now need to keep track of which side the current diff is for,
HEAD<->index or index<->working directory. Consequently we need
an additional "current diff" variable to tell us which side the
diff is for. Since this is really only necessary in reshow_diff
I'm going to declare a new global, rather than try to shove both
the path and the side into current_diff.
To keep things clear later on, I'm renaming current_diff to
current_diff_path. There is no functionality change in this
commit.

Its possible for the user to select a branch for the merge test
(while deleting branches) and also select that branch for deletion.
Doing so would have bypassed our merge check for that branch, as
a branch is always a strict subset of itself. So we will simply
skip over a branch and not delete it if that is the branch which
the user selected for the merge check.
Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
If the user is deleting a branch which is fully merged into the
selected test branch we should not confirm the delete with them,
the fact that the branch is fully merged means we can recover the
branch and no work will be lost.
If a branch is not fully merged, we should warn the user about which
branch(es) that is and continue deleting those which are fully merged.
We should only delete a branch if the user disables the merge check,
and in that case we should confirm with the user that a delete should
occur as this may cause them to lose changes.

The only reason the commit_prehook logic was broken out into its own
proc was so it could be invoked after the current set of files that
were already added to the commit could be refreshed if 'Allow Partially
Added Files' was set to false. Now that we no longer even offer that
option to the user there is no reason to keep this code broken out
into its own procedure.

Now that we take the approach of core Git where we allow the user to

On Mac OS X wish does not draw borders around text fields, making the

Most of the time when you are deleting branches you want to delete

Users can now delete a local branch by selecting from a list of
available branches. The list automatically does not include
the current branch, as deleting the current branch could be quite
dangerous and should not be supported.
The user may also chose to have us verify the branches are fully
merged into another branch before deleting them. By default we
select the current branch, matching 'git branch -d' behavior,
but the user could also select any other local branch.

Users may now create new branches by activating the Branch->Create menu
item. This opens a dialog which lets the user enter the new branch
name and select the starting revision for the new branch.
For the starting revision we allow the user to either select from a

SHA1 expression. For either creation technique we run the starting
revision through rev-parse to verify it is valid before trying to
create the ref with update-ref.

Rather than relying on the file state and just inverting it, we should
look at which file icon the user clicked on. If they clicked on the
one in the "Changes To Be Committed" list then they want to unstage
the file. If they clicked on the icon in the "Changed But Not Updated"
list then they want to add the file to the commit. This should be much
more reliable about capturing the user's intent then looking at the file
state.

Now that core Git refers to resetting paths in the index as "unstaging"

The DM state cannot really happen. Its implying that the file has

Apparently my earlier suspicion that the file state DD was a bug was
correct. A file which has been deleted from the working directory and
from the index will always get the state of D_ during a rescan. Thus
the only valid state for this to have is D_. We should always use only
D_ internally during our state changes.

This is a rather drastic change to the git-gui user interface, but it
doesn't really look any different yet. I've taken the two lists and
converted them to being "changes to be committed" and "changed but
not updated". These lists correspond to the same lists output by
git-runstatus based on how files differ in the HEAD<->index and the
index<->working directory comparsions it performs.
This change is meant to correlate with the change in Git 1.5.0 where
we have brought the index more into the foreground and are trying to
teach users to make use of it as part of their daily operations.

The gitdir global variable is essentially read-only, and is used rather

changing all uses to invoke the procedure rather than access the global

Users often forget to repack their object database, then start to
complain about how slow it is to perform common operations after
they have collected thousands of loose objects in their objects
directory. A simple repack usually restores performance.
During startup git-gui now asks git-count-objects how many loose
objects exist, and if this number exceeds a hardcoded threshold
we suggest that the user compress the database (aka run 'git gc')
at this time. I've hardcoded this to 2000 objects on non-Windows
systems as there the filesystems tend to handle the ~8 objects
per directory just fine. On Windows NTFS and FAT are just so slow
that we really start to lag when more than 200 loose objects exist,
so the hardcoded threshold is much lower there.
