git-gui: Save geometry before the window layout is damaged

Because Tk does not assure us the order that it will process
children in before it destroys the main toplevel we cannot safely
save our geometry data during a "bind . <Destroy>" event binding.
The geometry may have already changed as a result of a one or
more children being removed from the layout. This was pointed
out in gitk by Mark Levedahl, and patched over there by commit
b6047c5a8166a71e01c6b63ebbb67c6894d95114.

So we now also use "wm protocol . WM_DELETE_WINDOW" to detect when
the window is closed by the user, and forward that close event to
our main do_quit routine.

git-gui: Give amend precedence to HEAD over MERGE_MSGShawn O. Pearce Mon, 11 Jun 2007 23:39:55 +0000 (19:39 -0400)

git-gui: Give amend precedence to HEAD over MERGE_MSG

Apparently git-commit.sh (the command line commit user interface in
core Git) always gives precedence to the prior commit's message if
`commit --amend` is used and a $GIT_DIR/MERGE_MSG file also exists.

We actually were doing the same here in git-gui, but the amended
message got lost if $GIT_DIR/MERGE_MSG already existed because
we started a rescan immediately after loading the prior commit's
body into the edit buffer. When that happened the rescan found
MERGE_MSG existed and replaced the commit message buffer with the
contents of that file. This meant the user never saw us pick up
the commit message of the prior commit we are about to replace.

Johannes Sixt <J.Sixt@eudaptics.com> found this bug in git-gui by
running `git cherry-pick -n $someid` and then trying to amend the
prior commit in git-gui, thus combining the contents of $someid
with the contents of HEAD, and reusing the commit message of HEAD,
not $someid. With the recent changes to make cherry-pick use the
$GIT_DIR/MERGE_MSG file Johannes saw git-gui pick up the message
of $someid, not HEAD. Now we always use HEAD if we are amending.

checkout: do not get confused with ambiguous tag/branch names

Although it is not advisable, we have always allowed a branch
and a tag to have the same basename (i.e. it is not illegal to
have refs/heads/frotz and refs/tags/frotz at the same time).
When talking about a specific commit, the interpretation of
'frotz' has always been "use tag and then check branch",
although we warn when ambiguities exist.

However "git checkout $name" is defined to (1) first see if it
matches the branch name, and if so switch to that branch; (2)
otherwise it is an instruction to detach HEAD to point at the
commit named by $name. We did not follow this definition when
$name appeared under both refs/heads/ and refs/tags/ -- we
switched to the branch but read the tree from the tagged commit,
which was utterly bogus.

git-gui: Favor the original annotations over the recent ones

Usually when you are looking at blame annotations for a region of
a file you are more interested in why something was originally
done then why it is here now. This is because most of the time
when we get original annotation data we are looking at a simple
refactoring performed to better organize code, not to change its
semantic meaning or function. Reorganizations are sometimes of
interest, but not usually.

We now show the original commit data first in the tooltip. This
actually looks quite nice as the original commit will usually have an
author date prior to the current (aka move/copy) annotation's commit,
so the two commits will now tend to appear in chronological order.

I also found myself to always be clicking on the line of interest
in the file column but I always wanted the original tracking data
and not the move/copy data. So I changed our default commit from
$asim_data (the simple move/copy annotation) to the more complex
$amov_data (the -M -C -C original annotation).

git-gui: Improve our labeling of blame annotation types

It feels wrong to call the -M -C -C annotations "move/copy tracking"
as they are actually the original locations. So I'm relabeling
the status bar to show "copy/move tracking annotations" for the
current file (no -M -C -C) as that set of annotations tells us who
put the hunk here (who moved/copied it). I'm now calling the -M
-C -C pass "original location annotations" as that's what we're
really digging for.

I also tried to clarify some of the text in the hover tooltip.

git-gui: Use three colors for the blame viewer background

To prevent neighboring lines that are different commits from using
the same background color we now use 3 colors and assign them
by selecting the color that is not used before or after the line
in question. We still color "on the fly" as we receive hunks from
git-blame, but we delay our color decisions until we are getting
the original location data (the slower -M -C -C pass) as that is
usually more fine-grained than the current location data.

Credit goes to Martin Waitz for the tri-coloring concept.

git-gui: Jump to original line in blame viewer

When the user clicks on a commit link within one of the columns
in the blame viewer we now jump them not just to that commit/file
pair but also to the line of the original file. This saves the
user a lot of time, as they don't need to search through the new
file data for the chunk they were previously looking at.

We also restore the prior view when the user clicks the back button
to return to a pior commit/file pair that they were looking at.

Turned out this was quite tricky to get working in Tk. Every time
I tried to jump the text widgets to the correct locations by way
of the "yview moveto" or "see" subcommands Tk performed the change
until the current event finished dispatching, and then reset the
views back to 0, making the change never take place. Forcing Tk
to run the pending events before we jump the UI resolves the issue.

git-gui: Run blame twice on the same file and display both outputs

We now perform two passes over any input file given to the blame
viewer. Our first pass is a quick "git-blame" with no options,
getting the details of how each line arrived into this file. We
are specifically ignoring/omitting the rename detection logic as
this first pass is to determine why things got into the state they
are in.

Once the first pass is complete and is displayed in the UI we run
a second pass, using the much more CPU intensive "-M -C -C" options
to perform extensive rename/movement detection. The output of this
second pass is shown in a different column, allowing the user to see
for any given line how it got to be, and if it came from somewhere
else, where that is.

This is actually very instructive when run on our own lib/branch.tcl
script. That file grew recently out of a very large block of code
in git-gui.sh. The first pass shows when I created that file, while
the second pass shows the original commit information.

git-gui: Rename fields in blame viewer to better descriptions

Calling the commit message pane $w_cmit is a tad confusing when
we also have the $w_cgrp column that shows the abbreviated SHA-1s.

So w_cmit -> w_cviewer, as it is the "commit viewer"; and
w_cgrp -> w_amov as it is the "annotated commit + move tracking"
column. Also changed line_data -> amov_data, as that list is
exactly the results shown in w_amov.

Why call the column "move tracking"? Because this column holds
data from "git blame -M -C". I'm considering adding an additional
column that holds the data from "git blame" without -M/-C, showing
who did the copy/move, and when they did it.

git-gui: Switch internal blame structure to Tcl lists

The Tcl list datatype is significantly faster to work with than
the array type, especially if our indexes are a consecutive set
of numbers, like say line numbers in a file.

This rather large change reorganizes the internal data structure
of the blame viewer to use a proper Tcl list for the annotation
information about a line. Each line is given its own list within
the larger line_data list, where the indexes correspond to various
facts about that particular line.

The interface does seem to be more responsive this way, with less
time required by Tcl to process blame, and to switch to another
version of the same file. It could just be a placebo effect, but
either way most Tcl experts perfer lists for this type of work over
arrays.

The code to handle our three different text widgets is a bit
on the messy side as we issue the same command on all three

column added into the sequence, or removed from it.

We also now delete the tags we create for each commit when
we switch to display another "commit:path" pair. This way the

The colors were moved to fields, so they appear inside of the
blame viewer instance. This keeps two different concurrently
running blame viewers from stepping on each other's ordering
of the colors in group_colors.

Most of the other fields were moved around a little bit so
that they are organized by major category and value lifespan.

out is trivial compared to the time it will take Git to fully do

Most source code files are under 9,999 lines of text, so using a

Unfortunately when I added the right margin earlier (when I removed

margin. This put the line numbers too close to the commit column in

On Mac OS X the OS has "features" that like to draw thick black
borders around the text field that has focus. This is nice if
you want to know where your text is going and are blind as a bat,
but it isn't the best thing to have in a table that is being
faked through the abuse of Tk text widgets.

By setting our takefocus, highlightthickness and padx/y we can
get rid of this border and get our text widgets packed right next
to each other, with no padding between them. This makes the blame
background color smoothly run across the entire line of commit data,
line number and file content.

git-gui: Remove the loaded column from the blame viewer

Originally I had placed this loaded column between the line number
and the file line data to help users know if a particular line has
received annotation data or not yet. This way users would know if
the line(s) they were interested in were ready for viewing, or if
they still had to wait. It also was an entertaining way for the
user to spend their time waiting for git-blame --incremental to
compute the complete set of annotations.

However it is completely useless now that we show the abbreviated
commit SHA-1 and author initials in the leftmost column. That area
is empty until we get the annotation data, and as soon as we get it
in we display something there, indicating to the user that there is
now blame data ready. Further with the tooltips the user is likely
to see the data as soon as it comes in, as they are probably not
keeping their mouse perfectly still. So I'm removing the field to
save screen space for more useful things, like file content.

git-gui: Allow digging through history in blame viewer

gitweb has long had a feature where the user can click on any
commit the blame display and go visit that commit's information
page. From the user could go get the blame display for the file
they are tracking, and try to digg through the history of any
part of the code they are interested in seeing.

We now offer somewhat similiar functionality in git-gui. The 4
digit commit abreviation in the first column of our blame view is
now offered as a hyperlink if the commit isn't the one we are now
viewing the blame output for (as there is no point in linking back
to yourself). Clicking on that link will stop the current blame
engine (if still running), push the new target commit onto the
history stack, and restart the blame viewer at that commit, using
the "original file name" as supplied by git-blame for that chunk
of the output.

Users can navigate back to a version they had been viewing before
by way of a back button, which offers the prior commits in a popup
menu displayed right below the back button. I'm always showing the
menu here as the cost of switching between views is very high; you
don't want to jump to a commit you are not interested in looking at
again.

During switches we throw away all data except the cached commit data,
as that is relatively small compared to most source files and their
annotation marks. Unfortunately throwing this per-file data away in
Tcl seems to take some time; I probably should move the line indexed
arrays to proper lists and use [lindex] rather than the array lookup
(usually lists are faster).

We now start the git-blame process using "nice", so that its priority
will drop hopefully below our own. If I don't do this the blame engine
gets a lot of CPU under Windows 2000 and the git-gui user interface is
almost non-responsive, even though Tcl is just sitting there waiting
for events.

git-gui: Display a progress bar during blame annotation gathering

Computing the blame records for a large file with a long project
history can take git a while to run; traditionally we have shown
a little meter in the status area of our blame viewer that lets
the user know how many lines have been finished, and how far we
are through the process.

Usually such progress indicators are drawn with a little progress
bar in the window, where the bar shows how much has been completed
and hides itself when the process is complete. I'm using a very
simple hack to do that: draw a canvas with a filled rectangle.

Of course the time remaining has absolutely no relationship to the
progress meter. It could take very little time for git-blame to get
the first 90% of the file, and then it could take many times that to
get the remaining 10%. So the progress meter doesn't really have any
sort of assurances that it relates to the true progress of the work.
But in practice on some ugly history it does seem to hold a reasonable
indicator to the completion status. Besides, its amusing to watch and
that keeps the user from realizing git is being somewhat slow.

git-gui: Allow the user to control the blame/commit... Shawn O. Pearce Fri, 1 Jun 2007 21:55:43 +0000 (17:55 -0400)

git-gui: Allow the user to control the blame/commit split point

At one point I tried to present the blame viewer to an audience of
people on a 640 by 480 pixel LCD projector. This did not work at
all as the top area (the file data) was taking up all of the screen
realestate and the split point was not adjustable by the user. In
general locking the user into a specific ratio of display is just
not user friendly.

So we now place a split pane control into the middle of our blame
window, so the user can adjust it to their current needs. If the
window increases (or decreases) in height we assign the difference
to the file data area, as that is generally the area of the window
that users are trying to see more of when they grow the window.

Unfortunately there appears to be a bug in the "pack" layout manager
in Tcl/Tk 8.4.1. The status bar and the lower commit pane was being
squashed if the window decreased in height. I think the pack manager
was just not decreasing the size of the panedwindow slave properly if
the main window shrank. Switching to the "grid" layout manager fixes
the problem, but is slightly uglier setup code.

git-gui: Show author initials in blame groups

Frequently when I'm looking at blocks of code in the blame
viewer I want to know who is the culprit, or who I should
be praising for a job well done. The tooltips nicely show
this if I mouse over a block, but it doesn't work to get
this detail at a glance.

Since we don't use the leftmost commit column for anything
after the first line within a commit group I'm now tossing
the author's initials into that field, right justified. It
is quite clearly not a SHA-1 number as we always show the
SHA-1 in lowercase, while we explicitly select only the
uppercase characters from an author's name field, and only
those that are following whitespace.

I'm using initials here over anything else as they are quite
commonly unique within small development teams. The leading
part of the email address field was out for some of the teams
I work with, as there the email addresses are all of the form
"Givenname.Surname@initech.com". That will never fit into the
4 characters available.

git-gui: Simplify consecutive lines that come from the same commit

If two consecutive lines in the final file came from the same commit
then we store a "|" in the first column rather than the commit id,
for the second and subsequent lines in that block. This cleans up
the interface so runs associated with the same commit can be more
easily seen visually.

We also now use the abbreviation "work" for the uncommitted stuff in
your working directory, rather than "0000". This looks nicer to the
eyes and explains pretty quickly what is going on.

There was also a minor bug in the commit abbreviation column for the
last line of the file. This is now also fixed.

git-gui: Improve the coloring in blame viewer

The git-gui blame viewer has always been ugly as s**t. Linus Torvalds
suggested the coloring scheme I'm using here, which is two different
shades of grey for the background colors, and black text on a pale green
background for the currently selected/focused commit.

The difference is a massive improvement. The interface no longer will
cause seizures in people who are prone to that sort of thing. It no
longer uses a very offensive hot pink. The green being current actually
makes sense. And not having the background of the other non-current
lines change when you change the current commit is really a big deal.

Most of this is a hack. We try to determine if the path of our master

This should be true if $(gitexecdir) and $(libdir) have the same prefix.

Fix mishandling of $Id$ expanded in the repository... Andy Parkins Fri, 25 May 2007 10:50:08 +0000 (11:50 +0100)

Fix mishandling of $Id$ expanded in the repository copy in convert.c

If the repository contained an expanded ident keyword (i.e. $Id:XXXX$),
then the wrong bytes were discarded, and the Id keyword was not
expanded. The fault was in convert.c:ident_to_worktree().

Previously, when a "$Id:" was found in the repository version,
ident_to_worktree() would search for the next "$" after this, and
discarded everything it found until then. That was done with the loop:

do {
ch = *cp++;
if (ch == '$')
break;
rem--;
} while (rem);

The above loop left cp pointing one character _after_ the final "$"
(because of ch = *cp++). This was different from the non-expanded case,
were cp is left pointing at the "$", and was different from the comment
which stated "discard up to but not including the closing $". This
patch fixes that by making the loop:

do {
ch = *cp;
if (ch == '$')
break;
cp++;
rem--;
} while (rem);

That is, cp is tested _then_ incremented.

This loop exits if it finds a "$" or if it runs out of bytes in the
source. After this loop, if there was no closing "$" the expansion is
skipped, and the outer loop is allowed to continue leaving this
non-keyword as it was. However, when the "$" is found, size is
corrected, before running the expansion:

size -= (cp - src);

This is wrong; size is going to be corrected anyway after the expansion,
so there is no need to do it here. This patch removes that redundant
correction.

To help find this bug, I heavily commented the routine; those comments
are included here as a bonus.

git-am: use printf instead of echo on user-supplied... Jeff King Sat, 26 May 2007 03:42:36 +0000 (23:42 -0400)

git-am: use printf instead of echo on user-supplied strings

Under some implementations of echo (such as that provided by
dash), backslash escapes are recognized without any other
options. This means that echo-ing user-supplied strings may
cause any backslash sequences in them to be converted. Using
printf resolves the ambiguity.

This bug can be seen when using git-am to apply a patch
whose subject contains the character sequence "\n"; the
characters are converted to a literal newline. Noticed by
Szekeres Istvan.

name-rev: tolerate clock skew in committer datesJunio C Hamano Thu, 24 May 2007 19:20:42 +0000 (12:20 -0700)

name-rev: tolerate clock skew in committer dates

In git.git repository, "git-name-rev v1.3.0~158" cannot name the
rev, while adjacent revs can be named.

This was because it gives up traversal from the tips of existing
refs as soon as it sees a commit that has older commit timestamp
than what is being named. This is usually a good heuristics,
but v1.3.0~158 has a slightly older commit timestamp than
v1.3.0~157 (i.e. it's child), as these two were made in a
separate repostiory (in fact, in a different continent).

This adds a hardcoded slop value (1 day) to the cut-off
heuristics to work this kind of problem around. The current
algorithm essentially runs around from the available tips down
to ancient commits and names every single rev available that are
newer than cut-off date, so a single day slop would not add that
much overhead in repositories with long enough history where the
performance of name-rev matters.

I think the algorithm could be made a bit smarter by deepening
the graph on demand as a new commit is asked to be named (this
would require rewriting of name_rev() function not to recurse
itself but use a traversal list like revision.c traverser does),
but that would be a separate issue.

Correct key bindings to Control-<foo>Shawn O. Pearce Thu, 24 May 2007 06:33:13 +0000 (02:33 -0400)

Correct key bindings to Control-<foo>

Alberto Bertogli reported on #git that git-gui was exiting with
alt-q, while gitk on the same system was exiting with ctrl-q.
That was not what I wanted. I really wanted M1B to be bound to
the Control key on most non-Mac OS X platforms, but according to
Sam Vilain M1 on most systems means alt. Since gitk always does
control, I'm doing the same thing for all non-Mac OS X systems.

Update bash completion for git-config options

A few new configuration options grew out of the woodwork during the
1.5.2 series. Most of these are pretty easy to support a completion
of, so we do so.

I wanted to also add completion support for the <driver> part of
merge.<driver>.name but to do that we have to look at all of the
.gitattributes files and guess what the unique set of <driver>
strings would be. Since this appears to be non-trivial I'm punting
on it at this time.

Teach bash completion about recent log long options

(Somewhat) recently git-log learned about --reverse (to show commits
in the opposite order) and a looong time ago I think it learned
about --raw (to show the raw diff, rather than a unified diff).
These are both useful options, so we should make them easy for the
user to complete.

Teach bash completion about 'git remote update'

Recently the git-remote command grew an update subcommand, which
can be used to execute git-fetch across multiple repositories
in a single step. These can be configured with the 'remotes.*'
configuration options, so we can offer completion for any name that
matches and appears to be useful to git-remote update.
