git-gui: Attach font_ui to all spinbox widgets
For quite a while we have been assuming the user is running on
a Tcl/Tk 8.4 or later platform. This may not be the case on
some very old systems. Unfortunately I am pretty far down the
path of using the Tcl/Tk 8.4 commands and options and cannot

To improve performance on fork+exec impoverished systems (such as
Windows) we want to avoid running git-symbolic-ref on every rescan
if we can do so. A quick way to implement such an avoidance is to
just read the HEAD ref ourselves; we'll either see it as a symref
(starts with "ref: ") or we'll see it as a detached head (40 hex
digits). In either case we can treat that as our current branch.

Git has supported remote branch deletion for quite some time, but
I've just never gotten around to supporting it in git-gui. Some
workflows have users push short-term branches to some remote Git
repository, then delete them a few days/weeks later when that topic
has been fully merged into the main trunk. Typically in that style
of workflow the user will want to remove the branches they created.
We now offer a "Delete..." option in the Push menu, right below the
generic "Push..." option. When the user opens our generic delete
dialog they can select a preconfigured remote, or enter a random
URL. We run `git ls-remote $url` to obtain the list of branches and
tags known there, and offer this list in a listbox for the user to
select one or more from.
Like our local branch delete dialog we offer the user a way to filter
their selected branch list down to only those branches that have been
merged into another branch. This is a very common operation as the
user will likely want to select a range of topic branches, but only
delete them if they have been merged into some sort of common trunk.
Unfortunately our remote merge base detection is not nearly as strict
as the local branch version. We only offer remote heads as the test
commit (not any local ones) and we require that all necessary commits
to successfully run git-merge-base are available locally. If one or
more is missing we suggest that the user run a fetch first.
Since the Git remote protocol doesn't let us specify what the tested
commit was when we evaluated our decision to execute the remote delete
there is a race condition here. The user could do a merge test against
the trunk, determine a topic branch was fully merged, but before they
can start pushing the delete request another user could fast-forward
the remote topic branch to a new commit that is not merged into the
trunk. The delete will arrive after, and remove the topic, even though
it was not fully merged.

Git's native command line interface has had branch renaming
support for quite a while, through the -m/-M options to the
git-branch command line tool. This is an extremely useful
feature as users may decide that the name of their current
branch is not an adequate description, or was just entered
incorrectly when it was created.
Even though most people would consider git-branch to be a
Porcelain tool I'm using it here in git-gui as it is the
only code that implements the rather complex set of logic
needed to successfully rename a branch in Git. Currently
that is along the lines of:
*) Backup the ref
*) Backup the reflog
*) Delete the old ref
*) Create the new ref
*) Move the backed up reflog to the new ref
*) Record the rename event in the reflog
*) If the current branch was renamed, update HEAD
*) If HEAD changed, record the rename event in the HEAD reflog
*) Rename the [branch "$name"] section in the config file
Since that is some rather ugly set of functionality to implement
and get right, and some of it isn't easily accessible through the
raw plumbing layer I'm just cheating by relying on the Porcelain.

In some workflows it is common for a large number of temporary
branches to be created in a remote repository, get fetched to
clients that typically only use git-gui, and then later have
those branches deleted from the remote repository once they have
been fully merged into all destination branches. Users of git-gui
would obviously like to have their local tracking branches cleaned
up for them, otherwise their local tracking branch namespace would
grow out of control.
The best known way to remove these tracking branches is to run
"git remote prune <remotename>". Even though it is more of a
Porcelain command than plumbing I'm invoking it through the UI,
because frankly I don't see a reason to reimplement its ls-remote
output filtering and config file parsing.
A new configuration option (gui.pruneduringfetch) can be used to
automatically enable running "git remote prune <remotename>" after
the fetch of that remote also completes successfully. This is off
by default as it require an additional network connection and is
not very fast on Cygwin if a large number of tracking branches have
been removed (due to the 2 fork+exec calls per branch).

Johannes Sixt asked me to try to avoid embedding the runtime location
of git-gui's library directory in the executable script. Not embedding
it helps the MinGW to be relocatable to another directory should a user
wish to install the programs in a directory other than the location the
packager wanted them to be installed into.
Most of this is a hack. We try to determine if the path of our master
git-gui script will be able to locate the lib by ../share/git-gui/lib.
This should be true if $(gitexecdir) and $(libdir) have the same prefix.
If they do then we defer the assignment of $(libdir) until runtime, and
we get it from $argv0 rather than embedding it into the script itself.

I'm finding it difficult to work with a 6,000+ line Tcl script
and not go insane while looking for a particular block of code.
Since most of the program is organized into different units of
functionality and not all users will need all units immediately
on startup we can improve things by splitting procs out into
multiple files and let auto_load handle things for us.
This should help not only to better organize the source, but
it may also improve startup times for some users as the Tcl
parser does not need to read as much script before it can show
the UI. In many cases the user can avoid reading at least half
of git-gui now.
Unfortunately we now need a library directory in our runtime
location. This is currently assumed to be $(sharedir)/git-gui/lib
and its expected that the Makefile invoker will setup some sort of
reasonable sharedir value for us, or let us assume its going to be
$(gitexecdir)/../share.
We now also require a tclsh (in TCL_PATH) to just run the Makefile,
as we use tclsh to generate the tclIndex for our lib directory. I'm
hoping this is not an unncessary burden on end-users who are building
from source.

with trying to use "fconfigure $fd -encoding $enc" to select the
stream encoding and let Tcl's IO engine do all of the encoding work

channels to "-encoding binary" and then performing the encoding
work themselves using "encoding convertfrom" and "convertto", as
that was the only way I could make UTF-8 filenames work properly.

Mark Levedahl noticed that git-gui will let you create an empty
normal (non-merge) commit if the file state in the index is out
of whack. The case Mark was looking at was with the new autoCRLF
feature in git enabled and is actually somewhat difficult to create.
I found a different way to create an empty commit: turn on the
Trust File Modifications flag, touch a file, rescan, then move
the file into the "Changes To Be Committed" list without looking
at the file's diff. This makes git-gui think there are files
staged for commit, yet the update-index call did nothing other
than refresh the stat information for the affected file. In
this case git-gui allowed the user to make a commit that did
not actually change anything in the repository.
Creating empty commits is usually a pointless operation; rarely
does it record useful information. More often than not an empty
commit is actually an indication that the user did not properly
update their index prior to commit. We should help the user out
by detecting this possible mistake and guiding them through it,
rather than blindly recording it.
After we get the new tree name back from write-tree we compare
it to the parent commit's tree; if they are the same string and
this is a normal (non-merge, non-amend) commit then something
fishy is going on. The user is making an empty commit, but they
most likely don't want to do that. We now pop an informational
dialog and start a rescan, aborting the commit.

As we frequently need to execute a Git subcommand and obtain
its returned output we are making heavy use of [exec git foo]
to run foo. As I'm concerned about possibly needing to carry
environment data through a shell on Cygwin for at least some
subcommands, I'm migrating all current calls to a new git
proc. This actually makes the code look cleaner too, as
we aren't saying 'exec git' everywhere.

Rather than trying to mark the background color of the line numbers
to show which lines have annotated data loaded, we now show a ruler
between the line numbers and the file data. This ruler is just 1
character wide and its background color is set to grey to denote
which lines have annotation ready. I had to make this change as I
kept loosing the annotation marker when a line was no longer colored
as part of the current selection.
We now color the lines blamed on the current commit in yellow, the
lines in the commit which came after (descendant) in red (hotter,
less tested) and the lines in the commit before (ancestor) in blue
(cooler, better tested).

To help clue users into the fact that annotation data arrives
incrementally, and that they should try to locate the region
they want while the tool is running, we jump to the first line
of the first annotation if the user has not already clicked on
a line they are interested in and if the window is still looking
at the very top of the file.
Since it takes a second (at least on my PowerBook) to even generate
the first annotation for git-gui.sh, the user should have plenty of
time to adjust the scrollbar or click on a line even before we get
that first annotation record in, which allows the user to bypass
our automatic jumping.

Using 180 columns worth of screen space to display just 20 columns of
file data and 160 columns worth of annotation information is not
practically useful. Users need/want to see the file data, and have
the anotation associated with it displayed in a detail pane only when
they have focused on a particular region of the file.
Now our file viewer has a small 10-line high pane below the file
which shows the commit message for the commit this line was blamed
on. The columns have all been removed, except the current line
number column as that has some real value when trying to locate an
interesting block.
To keep the user entertained we have a progress meter in the status
bar of the viewer which lets them know how many lines have been
annotated, and how much has been completed. We use a grey background
on the line numbers for lines which we have obtained annotation from,
and we color all lines in the current commit with a yellow background,
so they stand out when scanning through the file. All other lines
are kept with a white background, making the yellow really pop.

Viewing annotated files is one of those tasks that is relatively
difficult to do in a simple vt100 terminal emulator. The user
really wants to be able to browse through a lot of information,

Now users can start our file viewer with annotations by running
'git gui blame commit path', thereby seeing the contents of the

Users want to navigate the file list shown in our branch browser
windows using the keyboard. So we now support basic traversal
with the arrow keys:

Return: Move into the subtree, or open the annotated file.
M1-Right: Ditto.
M1-Up: Move to the parent tree.
M1-Left: Ditto.
Probably the only feature missing from this is to key a leading part

To help the user visually see which lines are associated with each other

most files don't have that property.
What we really need to do is look at what colors are used by our

conflict with our neighbor. If we have run out of colors then we
should force our neighbor to recolor too. Yes, its the graph coloring

Using a panedwindow to display the blame viewer's individual columns
just doesn't make sense. Most of the important data fits within the
columns we have allocated, and those that don't the leading part fits

viewer to let the user sanely control individual column widths. This
change shouldn't really be an issue for most git-gui users as their
displays should be large enough to accept this massive dump of data.
We now also have a properly working horizontal scrollbar for the

If the user double clicks on a file within the browser we open it in

that Linus just added yesterday to core Git. Fortunately the feature
will be in 1.5.0 final so we can rely on having it available here.

Running on Cygwin is different than if we were running through MinGW.
In the Cygwin case we have cygpath available to us, we need to perform
UNIX<->Windows path translation sometimes, and we need to perform odd
things like spawning our own login shells to perform network operations.
But in the MinGW case these don't occur. Git knows native Windows file
paths, and login shells may not even exist.
Now git-gui will avoid running cygpath unless it knows its on Cygwin.
It also uses a different shortcut type when Cygwin is not present, and
it avoids invoking /bin/sh to execute hooks if Cygwin is not present.
This latter part probably needs more testing in the MinGW case.
This change also improves how we start gitk. If the user is on any type
of Windows system its known that gitk won't start right if ~/.gitk exists.
So we delete it before starting if we are running on any type of Windows
operating system. We always use the same wish executable which launched
git-gui to start gitk; this way on Windows we don't have to jump back to
/bin/sh just to go into the first wish found in the user's PATH. This
should help on MinGW when we probably don't want to spawn a shell just
to start gitk.

Users may want to be able to read Git documentation, even if they

terms covered within the standard Git documentation which would be
useful to even non command line using people.
We now try to offer an 'Online Documentation' menu option within the

setup. We default to instaweb.browser, if set, as this is probably
accurate for the user's configuration. If not then we try to guess
based on the operating system and the available browsers for each.
We prefer documentation which is installed parallel to Git's own
executables, e.g. `git --exec-path`/../Documentation/index.html, as
that is how I typically install the HTML docs. If those are not found

allowing the user to adjust the verbosity level of the recursive
merge strategy. I happen to like level 1 and suggest that other users
use that, but level 2 is the core Git default right now so we'll use
the same default in git-gui.

If an octopus merge goes horribly wrong git-merge will leave the

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

Technically the new git-gc command is strictly Porcelain; its invoking
multiple plumbing commands to do its work. Since git-gui tries to not

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

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.

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.

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
clean up old and inactive index files.

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
any data we are receiving from it by way of a pipe, or sending to it
by way of a pipe must be formatted in that encoding. This should
be the same as the Tcl system encoding, as its the encoding that
applications should be using to converse with the operating system.
Sadly this does not fix the gitweb/test file in git.git on Macs;
that's due to something really broken happening in the filesystem.

This newline is stupid; it doesn't get put here unless the file
is very large, and then its just sort of out of place.

Users may want to know what a file is before they add it to the
repository, especially if its a binary file. So when possible
invoke 'file' on the path and try to get its output. Since
this is strictly advice to the user we won't bother to report
any failures from our attempt to run `file`.
Since some file commands also output the path name they were
given we look for that case and strip it off the front of the
returned output before placing it into the diff viewer.

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.

If one or both versions of the file don't have a newline at the end
of the file we get a line telling us so in the diff output. This
shouldn't be tagged, nor should it generate a warning about not
being tagged.

Sometimes the Select All action from our context menus doesn't work
unless the text field its supposed to act on has focus. I'm not
really sure why adding the sel tag requires having focus. It
technically should not be required to update the sel tag membership,
but perhaps there is a bug in Tcl/Tk 8.4.1 on Windows which is
causing this odd behavior.

We don't want to tag these new file/delete file lines, as they aren't
actually that interesting. Its quite clear from the diff itself that
the file is a new file or is a deleted file (as the entire thing will
appear in the diff).

Its possible for external programs to update file modification dates of
many files within a repository. I've seen this on Windows with a popular
virus scanner, sadly enough. If the user has Trust File Modification
Timestamp enabled and the virus scanner touches a large number of files
it can be annoying trying to clear them out of the 'Changed But Not
Updated' file list by clicking on them one at a time to load the diff.
So now we force a rescan as soon as one such file is found, and for
just that rescan we disable the Trust File Modification Timestamp option
thereby allowing Git to update the modification dates in the index.

If we are making an initial commit our branch head did not exist when
we scanned for all heads during startup. Consequently we won't have

I didn't really like the way a new git-gui launched in a new repository
as the window geometry wasn't quite the best layou. So this is a minor
tweak to try and get space distributed around the window better.
By decreasing the widths we're also able to shrink the gui smaller
without Tk clipping content at the edge of the window. A nice feature.

Up until now git-gui did not support the new wildcard syntax used to
fetch any remote branch into a tracking branch during 'git fetch'. Now
if we identify a tracking branch as ending with the string '/*' then
we use for-each-ref to print out the reference names which may have
been fetched by that pattern. We also now correctly filter any
tracking branches out of refs/heads, if they user has placed any there.

If the user is tabbing through fields in the options dialog they are
likely to want to just enter a new value for the field, rather than
edit the value in-place. This is easier if we select the entire value

When we are in a dialog such as the new branch dialog or our options
dialog we should permit the user to traverse around through the available
widgets with their Tab/Shift-Tab key combinations. So in any single
line text field where we don't want tab characters to actually be
inserted into the value rebind Tab and Shift-Tab to honor what the
tk_focusPrev and tk_focusNext scripts recommend.

Typically I'm creating all new branches with the same prefix, e.g. 'sp/'.
So its handy to be able to setup a repository (or global) level config
option for git gui which contains this initial prefix. Once set then
git-gui will load it into the new branch name field whenever a new
branch is being created.

New branches must have a name. An empty one is not a valid ref, but the
generic message "We do not like '' as a branch name." is just too vague
or difficult to read. So detect the missing name early and tell the
user it must be entered.

I refactored the common code related to tracking branch listing into
a new procedure all_tracking_branches. This saves a few lines and
should make the create and delete dialogs easier to maintain.
We now don't offer a radio button to create from a tracking branch
or merge-check a tracking branch if there are no tracking branches
known to git-gui. This prevents us from creating an empty option
list and letting the user try to shoot themselves in the foot by
asking us to work against an empty initial revision.

Some of my file paths in some of my repositories are very long, this
is rather typical in Java projects where the path name contains a deep
package structure and then the file name itself is rather long and
(hopefully) descriptive. Seeing these paths line wrap in the file lists
looks absolutely horrible. The entire rendering is almost unreadable.
Now we draw both horizontal and vertical scrollbars for both file lists,
and we never line wrap within the list text itself.
