95af4d8de1 git-gui: Make sure remotes are loaded when picking revisions
If we are started for only a blame/browser/citool run we don't
usually initialize the list of remotes, or determine which refs
are tracking branches and which are local branch heads.  This is
because some of that work is relatively expensive and is usually
not going to be needed if we are started only for a blame, or to
make a single commit.

However by not loading the remote configuration we were crashing
if the user tried to open a browser for another branch through
the Repository menu, as our load_all_heads procedure was unable
to decide which refs/heads/ items were actually local heads.  We
now force all remote configuration data to be loaded if we have
not done so already and we are trying to create a revision mega
widget.

0fe055cd24 git-gui: Use progress bar while resetting/aborting files
Resetting a large number of files on a slow filesystem can take
considerable time, just as switching branches in such a case can
take more than two seconds.  We now take advantage of the progress
meter output by read-tree and show it in the main window status
bar, just like we do during checkout (branch switch).

bc318ea86d git-gui: Remove usernames from absolute SSH urls during merging
If we are being asked to merge a tracking branch that comes from a
remote repository accessed by the very common SSH URL format of
"user@host:/path/to/repo" then we really don't need the username
as part of the merge message, it only clutters up the history and
makes things more confusing.  So we instead clip the username part
off if the local filesystem path is absolute, as its probably not
going to be an ambiguous URL even when it is missing the username.

On the other hand we cannot clip the username off if the URL is
not absolute, because in such cases (e.g. "user@host:myrepo") the
directory that the repository path is resolved in is relative to
the user's home directory, and the username becomes important.

ead49f5a4f git-gui: Format tracking branch merges as though they were pulls
If we are merging a tracking branch we know exactly what remote URL
that branch is fetched from, and what its name is on that remote
repository.  In this case we can setup a merge message that looks
just like a standard `git-pull $remote $branch` operation by filling
out FETCH_HEAD before we start git-merge, and then run git-merge just
like git-pull does.

I think the result of this behavior is that merges look a lot nicer
when the came off of local tracking branches, because they no longer
say "commit 'origin/...'" to describe the commit being merged but
instead now mention the specific repository we fetched those commits
from.

350a35f0a1 git-gui: Replace merge dialog with our revision picker widget
Now that we only support merging one branch we can offer the user
a better user interface experience by allowing them to select the

This change neatly solves the problem of locating a branch out of
a sea of 200 tracking branches, and of dealing with very long branch

becafaace6 git-gui: Show ref last update times in revision chooser tooltips
If we can we now show the last modification date of a loose ref as
part of the tooltip information shown in the revision picker.  This
gives the user an indication of when was the last time that the ref
was modified locally, and may especially be of interest when looking
at a tracking branch.

If we cannot find the loose ref file than we try to fallback on the
reflog and scan it for the date of the last record.  We don't start
with the reflog however as scanning it backwards from the end is not
an easy thing to do in Tcl.  So I'm being lazy here and just going
through the entire file, line by line.  Since that is less efficient
than a single stat system call, its our fallback strategy.

844c3f6fe9 git-gui: Display commit/tag/remote info in tooltip of revision picker
Our revision chooser mega-widget now sets up tooltips for itself so
that it displays details about a commit (or a tag and the commit
it refers to) when the user mouses over that line in the filtered
ref list.  If the item is from a remote tracking branch then we also
show the remote url and what branch on that remote we fetch from, so
the user has a clear concept of where that revision data originated.

To help the merge dialog I've also added a new constructor that
makes the dialog only offer unmerged revisions (those not in HEAD),
as this allows users to avoid performing merges only to get "Already
up to date" messages back from core Git.

7d5266a704 git-gui: Avoid unnecessary symbolic-ref call during checkout
If we are checking out the branch we are already on then there is no
need to call symbolic-ref to update the HEAD pointer to the "new"
branch name, it is already correct.

Currently this situation does not happen very often, but it can be
seen in some workflows where the user always recreates their local
branch from a remote tracking branch and more-or-less ignores what
branch he/she is on right now.  As they say, ignorance is bliss.

This case will however become a tad more common when we overload
checkout_op to actually also perform all of our merges.  In that
case we will likely see that the branch we want to "checkout" is
the current branch, as we are actually just merging into it.

9c5a3c7797 git-gui: Paper bag fix quitting crash after commit
My earlier introduction of the GITGUI_BCK file (which saves the user's
commit message buffer while they are typing it) broke the Quit function.
If the user makes a commit we delete the GITGUI_BCK file; if they then
immediately quit the application we fail to rename the GITGUI_BCK file
to GITGUI_MSG.  This is because the file does not exist, but our flag
still says it does.  The root cause is we did not unset the flag during
commit.

7bd197c7ba git-gui: Fix unnecessary fast-forward during checkout
If we are trying to checkout a local branch which is matched to a
remote tracking branch, but the local branch is newer than the remote
tracking branch we actually just want to switch to the local branch.
The local branch is "Already up to date".

Unfortunately we tossed away the local branch's commit SHA-1 and kept
the remote tracking branch's SHA-1, which meant that the user lost the
local changes when we updated the working directory.  At least we did
not update the local branch ref, so the user's data was still intact.

We now toss the tracking branch's SHA-1 and replace with the local
branch's SHA-1 before the checkout, ensuring that we pass of the right
tree to git-read-tree when we update the working directory.

54febd4fe6 git-gui: Internally allow fetch without storing for future pull support
This is actually just an underlying code improvement that has no user
visible component yet.  UI improvements to actually fetch and merge via
an arbitrary remote with no tracking branches must still follow to make
this change useful for the end-user.

Our tracking branch specifications are a Tcl list of three components:

  - local tracking branch name
  - remote name/url
  - remote branch name/tag name

This change just makes the first element optional.  If it is an empty
string we will run the fetch, but have the value be saved only into the
special .git/FETCH_HEAD, where we can pick it up and use it for this one
time operation.

If our current repository HEAD is actually at the commit we are moving
to, and we agreed to perform this switch earlier, then we have no files
to update in the working directory and any stale mtimes are simply not
of consequence right now.  We can pretend like we ran a read-tree and

and setting the symbolic-ref.

If we are given a merge type we don't understand in checkout_op there
is probably a bug in git-gui somewhere that allowed this unknown merge
strategy to come into this part of the code path.  We currently only
recognize three merge types ('none', 'ff' and 'reset') but are going
to be supporting more in the future.  Rather than keep editing this
message I'm going with a very generic "Uh, we don't do that!" type of
error.

result is the same if the merge base of our target commit and the
existing commit is the existing commit: its a fast-forward as the
existing commit is fully contained in the target commit.

This minor cleanup in logic will make it easier to implement a
new kind of merge_type that actually merges the two trees with a
real merge strategy, such as git-merge-recursive.

4578c5cb69 git-gui: Automatically backup the user's commit buffer
A few users have been seeing crashes in Tk when using the undo key
binding to undo the last few keystroke events in the commit buffer.
Unfortunately that means the user loses their commit message and
must start over from scratch when the user restarts the process.

git-gui now saves the user's commit message buffer every couple of
seconds to a temporary file under .git (specifically .git/GITGUI_BCK).
At exit time we rename this file to .git/GITGUI_MSG if there is a
message, the file exists, and it is currently synchronized with the
Tk buffer.  Otherwise we do our usual routine of saving the Tk buffer
to .git/GITGUI_MSG and delete .git/GITGUI_BCK, if it exists.

During startup we favor .git/GITGUI_BCK over .git/GITGUI_MSG.  This
way a crash doesn't take out the user's message buffer but instead
will cause the user to lose only a few keystrokes.  Most people do
not type more than 200 WPM, and with 30 possible saves per minute
we are unlikely to lose more than 7 words.

5dc2cae6f4 git-gui: Completely remove support for creating octopus merges
I'm working on refactoring the UI of the merge dialog, because as it
currently stands the dialog is absolutely horrible, especially when
you have 200+ branches available from a single remote system.

In that refactoring I plan on using the choose_rev widget to allow
the user to select exactly which branch/commit they want to merge.
However since that only selects a single commit I'm first removing
the code that supports octopus merges.

A brief consultation on #git tonight seemed to indicate that the
octopus merge strategy is not as useful as originally thought when
it was invented, and that most people don't commonly use them.  So
making users fall back to the command line to create an octopus is
actually maybe a good idea here, as they might think twice before
they use it.

This reduces our script by a few lines for the single commit case

We now perform the check after we have been running for at least

floating out in no-mans-land like it did before on Mac OS X.

Johannes originally submitted a patch to this section of commit.tcl
to use `git rev-parse $PARENT:`, but not all versions of Git will
accept that format.  So I'm just taking the really simple approach
here of scanning the first line of the commit to grab its tree.

While I was working on this change I also converted all of our
existing pipes ([open "| git ..."]) to use two new pipe wrapper
functions.  These functions take additional options like --nice
and --stderr which instructs Tcl to take special action, like
running the underlying git program through `nice` (if available)
or redirect stderr to stdout for capture in Tcl.

the window that shows the current status of the blame engine, which
includes the number of lines completed as both a text and a graphical
meter.  I want to reuse this meter system in other places, such as
during a branch switch where read-tree -v can give us a progress
meter for any long-running operation.

This change extracts the code and refactors it as a widget that we
can take advantage of in locations other than in the blame viewer.

827c71199d git-gui: Allow double-click in checkout dialog to start checkout
If the user double clicks a branch in the checkout dialog then they
probably want to start the checkout process on that branch.  I found
myself doing this without realizing it, and of course it did nothing
as there was no action bound to the listbox's Double-Button-1 event
handler.  Since I did it without thinking, others will probably also
try, and expect the same behavior.

d41b43eb4c git-gui: Refactor branch switch to support detached head
This is a major rewrite of the way we perform switching between
branches and the subsequent update of the working directory.  Like
core Git we now use a single code path to perform all changes: our
new checkout_op class.  We also use it for branch creation/update
as it integrates the tracking branch fetch process along with a
very basic merge (fast-forward and reset only currently).

Because some users have literally hundreds of local branches we
use the standard revision picker (with its branch filtering tool)
to select the local branch, rather than keeping all of the local
branches in the Branch menu.  The branch menu listing out all of
the available branches is simply not sane for those types of huge
repositories.

Users can now checkout a detached head by ticking off the option
in the checkout dialog.  This option is off by default for the
obvious reason, but it can be easily enabled for any local branch
by simply checking it.  We also detach the head if any non local
branch was selected, or if a revision expression was entered.

699d5601f5 git-gui: Refactor our ui_status_value update technique
I'm really starting to dislike global variables.  The ui_status_value
global varible is just one of those that seems to appear in a lot of
code and in many cases we didn't even declare it "global" within the
proc that updates it so we haven't always been getting all of the
updates we expected to see.

This change introduces two new global procs:

  ui_status $msg;   # Sets the status bar to show $msg.
  ui_ready;         # Changes the status bar to show "Ready."

The second (special) form is used because we often update the area
with this message once we are done processing a block of work and
want the user to know we have completed it.

I'm not fixing the cases that appear in lib/branch.tcl right now
as I'm actually in the middle of a huge refactoring of that code
to support making a detached HEAD checkout.

7618e6b1c1 git-gui: Enhance choose_rev to handle hundreds of branches
One of my production repositories has hundreds of remote tracking
branches.  Trying to navigate these through a popup menu is just
not possible.  The list is far larger than the screen and it does
not scroll fast enough to efficiently select a branch name when
trying to create a branch or delete a branch.

This is major rewrite of the revision chooser mega-widget.  We
now use a single listbox for all three major types of named refs
(heads, tracking branches, tags) and a radio button group to pick
which of those namespaces should be shown in the listbox.  A filter
field is shown to the right allowing the end-user to key in a glob
specification to filter the list they are viewing.  The filter is
always taken as substring, so we assume * both starts and ends the
pattern the user wanted but otherwise treat it as a glob pattern.

This new picker works out really nicely.  What used to take me at
least a minute to find and select a branch now takes mere seconds.

774173aa5f git-gui: Fast-forward existing branch in branch create dialog
If the user elects to create a local branch that has the same name
as an existing branch and we can fast-forward the local branch to
the selected revision we might as well do the fast-forward for the
user, rather than making them first switch to the branch then merge
the selected revision into it.  After all, its really just a fast
forward.  No history is lost.  The resulting branch checkout may
also be faster if the branch we are switching from is closer to
the new revision.

Likewise we also now allow the user to reset the local branch if
it already exists but would not fast-forward.  However before we
do the actual reset we tell the user what commits they are going to
lose by showing the oneline subject and abbreviated sha1, and we also
let them inspect the range of commits in gitk.

6f2a3fc812 git-gui: Optimize for newstyle refs/remotes layout
Most people using Git 1.5.x and later are using the newer style
of remotes layout where all of their tracking branches are in
refs/remotes and refs/heads contains only the user's own local
branches.

In such a situation we can avoid calling is_tracking_branch
for each head we are considering because we know that all of
the heads must be local branches if no fetch option or Pull:
line maps a branch into that namespace.

If however any remote maps a remote branch into a local
tracking branch that resides in refs/heads we do exactly
what we did before, which requires scanning through all
fetch lines in case any patterns are matched.

I also switched some regexp/regsub calls to string match
as this can be a faster operation for prefix matching.

6233ab1729 git-gui: Teach class system to support [$this cmd] syntax
Its handy to be able to ask an object to do something for you by
handing it a subcommand.  For example if we want to get the value
of an object's private field the object could expose a method that
would return that value.  Application level code can then invoke
"$inst get" to perform the method call.

Tk uses this pattern for all of its widgets, so we'd certainly
like to use it for our own mega-widgets that we might develop.
Up until now we haven't needed such functionality, but I'm working
on a new revision picker mega-widget that would benefit from it.

To make this work we have to change the definition of $this to
actually be a procedure within the namespace.  By making $this a
procedure any caller that has $this can call subcommands by passing
them as the first argument to $this.  That subcommand then needs
to call the proper subroutine.

Placing the dispatch procedure into the object's variable namespace
ensures that it will always be deleted when the object is deleted.

c1fd897a25 git-gui: Start blame windows as tall as possible
Most users these days are using a windowing system attached to a
monitor that has more than 600 pixels worth of vertical space
available for application use.  As most files stored by Git are
longer than they are wide (have more lines than columns) we want
to dedicate as much vertical space as we can to the viewer.

Instead of always starting the window at ~600 pixels high we now
start the window 100 pixels shorter than the screen claims it has
available to it.  This -100 rule is used because some popular OSen
add menu bars at the top of the monitor, and docks on the bottom
(e.g. Mac OS X, CDE, KDE).  We want to avoid making our window too
big and causing the window's resize control from being out of reach
of the user.

0f32da53df 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).

put the hunk here (who moved/copied it).  I'm now calling the -M

really digging for.

usually more fine-grained than the current location data.

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.

172c92b475 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.

debcd0fd02 git-gui: Display the "Loading annotation..." message in italic
If the user clicks on a line region that we haven't yet received
an annotation for from git-blame we show them "Loading annotation".
But I don't want the user to confuse this loading message with a
commit whose first line is "Loading annotation" and think we messed
up our display somehow.  Since we never use italics for anything
else, I'm going with the idea that italic slant can be used to show
data is missing/elided out at the time being.

fc816d7b85 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.

c5db65aef3 git-gui: Label the uncommitted blame history entry
If the user runs the blame viewer on a working directory file
instead of a specific commit-ish then we have no value for the
commit SHA1 or the summary line; this causes the history menu
to get an empty entry at the very bottom.  We now look for this
odd case and call the meny entry "Working Directory".

2f85b7e4b4 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.

14c4dfd3d1 git-gui: Cleanup redundant column management in blame viewer
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
widgets one at a time.  Adding (or removing) columns from the
viewer is messy, as a lot of locations need to have the new
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
text viewer doesn't get bogged down with a massive number of tags
as we traverse through history.

c17c175133 git-gui: Better document our blame variables
The array variable "order" used to be used to tell us in what
order each commit was received in.  Recent changes have removed
that need for an ordering and the "order" array is now just a
boolean 'do we have that commit yet' flag.

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.

b61101579f git-gui: Remove unused commit_list from blame viewer
This list used to store the commits in the order we received
them in.  I originally was using it to update the colors of
the commit before and the commit after the current commit,
but since that interface concept turned out to be horribly
ugly and has been removed we no longer need this list.

81fb7efeda git-gui: Automatically expand the line number column as needed
After we finish reading a chunk of data from the file stream
we know how many digits we need in the line number column to
show the current maximum line number.  If our line number column
isn't wide enough, we should expand it out to the correct width.

Any file over our default allowance of 5 digits (99,999 lines)
is so large that the slight UI "glitch" when we widen the column
out is trivial compared to the time it will take Git to fully do
the annotations.

375e1365a6 git-gui: Make the line number column slightly wider in blame
Most source code files are under 9,999 lines of text, so using a
field width of 5 characters meant that we should have had one char
padding on the left edge (because we right-justify the line number).
Unfortunately when I added the right margin earlier (when I removed
the padding) I ate into the extra character's space, losing the left
margin.  This put the line numbers too close to the commit column in
any file with more than 999 lines in it.

000a10696c git-gui: Use lighter colors in blame view
The colors I originally picked out on a Mac OS X system look a
tad too dark on a Windows 2000 system; the greys are dark enough
to make it difficult to read some lines of text and the green used
to highlight the current commit was also difficult to read text on.

I also added a third grey to the mix, to try and help some files
that wind up with a number of neighboring chunks getting the same
colors.

063257076d git-gui: Remove unnecessary space between columns in blame viewer
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.

0eab69a4a9 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.

08dda17e00 git-gui: Use a label instead of a button for the back button
Apparently Tk on Mac OS X won't draw a button with an image using a
transparent background.  Instead it draws the button using some sort
of 3D effect, even though I asked for no relief and no border.  The
background is also not our orange that we expected it to be.

Earlier I had tried this same trick on Windows and it draws the same
way as the button did, so I'm going to switch to the label as that
seems to be more portable.

file is not the same as the file we are currently viewing.
