dd0962883b git-gui: Remove explicit references to 'aspell' in message strings
Users may or may not be using aspell here.  About the only thing
we are using that is aspell specific (and not supported by ispell
or an ispell variant) is some command line options when we start
up aspell, and a forced encoding of UTF-8.  Both of these can be
corrected and/or cleaned up by users through an aspell wrapper
script, or through further improvements to git-gui.  There is no
reason to require our translated strings to reference a specific
spell checker, especially if that spell checker implementation is
not very suitable for the language being translated.

f57ca1efe5 git-gui: Ensure all spellchecker 'class' variables are initialized
If we somehow managed to get our spellchecker instance created but
aspell wasn't startable we may not finish _connect and thus may
find one or more of our fields was not initialized in the instance.

If we have an instance but no version, there is no reason to show
a version to the user in our about dialog.  We effectively have no
spellchecker available.

aba15f7f59 git-gui: Ensure error dialogs always appear over all other windows
If we are opening an error dialog we want it to appear above all of
the other windows, even those that we may have opened with a grab
to make the window modal.  Failure to do so may allow an error
dialog to open up (and grab focus!) under an existing toplevel,
making the user think git-gui has frozen up and is unresponsive,
as they cannot get to the dialog.

95b002eeb3 git-gui: Automatically spell check commit messages as the user types
Many user friendly tools like word processors, email editors and web
browsers allow users to spell check the message they are writing
as they type it, making it easy to identify a common misspelling
of a word and correct it on the fly.

We now open a bi-directional pipe to Aspell and feed the message
text the user is editing off to the program about once every 300
milliseconds.  This is frequent enough that the user sees the results
almost immediately, but is not so frequent as to cause significant
additional load on the system.  If the user has modified the message
text during the last 300 milliseconds we delay until the next period,
ensuring that we avoid flooding the Aspell process with a lot of
text while the user is actively typing their message.

We wait to send the current message buffer to Aspell until the user
is at a word boundary, thus ensuring that we are not likely to ask
for misspelled word detection on a word that the user is actively
typing, as most words are misspelled when only partially typed,
even if the user has thus far typed it correctly.

Misspelled words are highlighted in red and are given an underline,
causing the word to stand out from the others in the buffer.  This is
a very common user interface idiom for displaying misspelled words,
but differs from one platform to the next in slight variations.
For example the Mac OS X system prefers using a dashed red underline,
leaving the word in the original text color.  Unfortunately the
control that Tk gives us over text display is not powerful enough
to handle such formatting so we have to work with the least common
denominator.

The top suggestions for a misspelling are saved in an array and
offered to the user when they right-click (or on the Mac ctrl-click)
a misspelled word.  Selecting an entry from this menu will replace
the misspelling with the correction shown.  Replacement is integrated
with the undo/redo stack so undoing a replacement will restore the
misspelled original text.

If Aspell could not be started during git-gui launch we silently eat
the error and run without spell checking support.  This way users
who do not have Aspell in their $PATH can continue to use git-gui,
although they will not get the advanced spelling functionality.

If Aspell started successfully the version line and language are
shown in git-gui's about box, below the Tcl/Tk versions.  This way
the user can verify the Aspell function has been activated.

If Aspell crashes while we are running we inform the user with an
error dialog and then disable Aspell entirely for the rest of this
git-gui session.  This prevents us from fork-bombing the system
with Aspell instances that always crash when presented with the
current message text, should there be a bug in either Aspell or in
git-gui's output to it.

We escape all input lines with ^, as recommended by the Aspell manual
page, as this allows Aspell to properly ignore any input line that is
otherwise looking like a command (e.g. ! to enable terse output).  By
using this escape however we need to correct all word offsets by -1 as
Aspell is apparently considering the ^ escape to be part of the line's
character count, but our Tk text widget obviously does not.

Available dictionaries are offered in the Options dialog, allowing
the user to select the language they want to spellcheck commit
messages with for the current repository, as well as the global
user setting that all repositories inherit.

Special thanks to Adam Flott for suggesting connecting git-gui
to Aspell for the purpose of spell checking the commit message,
and to Wincent Colaiuta for the idea to wait for a word boundary
before passing the message over for checking.

not been needed) but we get an update to the scroll port we may find
the scrollbar window exists but the Tcl command doesn't.  Apparently

removing the Tcl procedure name but still leaving the widget name in

ed76cb70f4 git-gui: Consolidate hook execution code into a single function
The code we use to test if a hook is executable or not differs on
Cygwin from the normal POSIX case.  Rather then repeating that for
all three hooks we call in our commit code path we can place the
common logic into a global procedure and invoke it when necessary.

This also lets us get rid of the ugly "|& cat" we were using before
as we can now rely on the Tcl 8.4 feature of "2>@1" or fallback to
the "|& cat" when necessary.

The post-commit hook is now run through the same API, but its outcome
does not influence the commit status.  As a result we now show any of
the errors from the post-commit hook in a dialog window, instead of on
the user's tty that was used to launch git-gui.  This resolves a long
standing bug related to not getting errors out of the post-commit hook
when launched under git-gui.

fb0ca475c6 git-gui: Honor the standard commit-msg hook
Under core Git the git-commit tool will invoke the commit-msg hook
if it exists and is executable to the user running git-commit.  As
a hook it has some limited value as it cannot alter the commit, but
it can modify the message the user is attempting to commit.  It is
also able to examine the message to ensure it conforms to some local
standards/conventions.

Since the hook takes the name of a temporary file holding the message
as its only parameter we need to move the code that creates the temp
file up earlier in our commit code path, and then pass through that
file name to the latest stage (where we call git-commit-tree).  We let
the hook alter the file as it sees fit and we don't bother to look at
its content again until the commit succeeded and we need the subject
for the reflog update.

a41e45ea1c git-gui: Refresh file status description after hunk application
If we apply a hunk in either direction this may change the file's
status.  For example if a file is completely unstaged, and has at
least two hunks in it and the user stages one hunk the file will
change from "Modified, not staged" to "Portions staged for commit".

Resetting the file path causes our trace on this variable to fire;
that trace is used to update the file header in the diff viewer to
the file's current status.

d36a8f73a4 git-gui: Allow 'Create New Repository' on existing directories
Often users setup a few source files and get a project rolling
before they create a Git repository for it.  In such cases the
core Git tools allow users to initialize a new repository by
simply running `git init` at the desired root level directory.

We need to allow the same situation in git-gui; if the user is
trying to make a new repository we should let them do that to any
location they chose.  If the directory already exists and already
has files contained within it we still should allow the user to
create a repository there.  However we still need to disallow
creating a repository on top of an existing repository.

d4e890e5de git-gui: Make sure we get errors from git-update-index
I'm seeing a lot of silent failures from git-update-index on
Windows and this is leaving the index.lock file intact, which
means users are later unable to perform additional operations.

When the index is locked behind our back and we are unable to
use it we may need to allow the user to delete the index lock
and try again.  However our UI state is probably not currect
as we have assumed that some changes were applied but none of
them actually did.  A rescan is the easiest (in code anyway)
solution to correct our UI to show what the index really has
(or doesn't have).

51a41ac4ef git-gui: Use proper Windows shortcuts instead of bat files
On Windows its better to use a shortcut (.lnk file) over a batch
script (.bat) as we can specify the icon file for the .lnk and
thus have these git specific objects appear on the desktop with
that git specific icon file.

Unfortunately the authors of Tcl did not bless us with the APIs
needed to create shortcuts from within Tcl.  But Microsoft did
give us Windows Scripting Host which allows us to execute some
JavaScript that calls some sort of COM object that can operate
on a .lnk file.

We now build both Cygwin and non-Cygwin "desktop icons" as proper
Windows .lnk files, using the "Start in" property of these files
to indicate the working directory of the repository the user wants
to launch.

24f7c64b21 git-gui: offer a list of recent repositories on startup
If git-gui is started outside a work tree the repository chooser
will offer a list of recently opened repositories.  Clicking on
any list entry directly opens the repository.

The list of recently opened repositories is stored in the config
as the multi-valued option gui.recentrepo. If the list grows beyond
10 entries it will be truncated by removing one of the older entries.

Only repositories that are opened through the repository chooser
will get added to the recent list.  Repositories opened from the
shell will not yet be added to the recent list, as users are likely
to have a way to easily return to the same directory via their shell.

[sp: This is actually a combined work from both Steffen and myself.

a7cb8f583f git-gui: Switch the git-gui logo to Henrik Nyh's logo
Henrik came up with this alternative logo for gitweb and posted
it on his blog:

  http://henrik.nyh.se/2007/06/alternative-git-logo-and-favicon

The msysGit port uses his logo within some of their components,
and frankly it looks better here in git-gui for our repository
setup wizard screen.  The logo fits quite nicely along the left
edge of our window, leaving significantly more vertical space
for things like the git-fetch console output.

Because the logo changes the layout charateristics of the setup
window I also needed to adjust some of the padding for our widgets
and stop using a fixed width window size.  We now let Tk compute
the correct size of the main window whenever the layout changes,
and drop the window into roughly the upper left 1/3 of the desktop
so its not quite centered but is likely to be far enough away from
any sort of task bars/menu bars/docks that the user may have along
any edge of the screen.

59213f60b7 git-gui: Don't delete scrollbars in console windows
If we have added a scrollbar to the console window because one
direction has too much text to fit in the available screen space
we should just keep the scrollbars.  Its annoying to watch our
horizontal scrollbar bounce in and out of the window as additional
text is inserted into the widget and the need for the scrollbar
comes and goes.

6f2d73ec0c git-gui: Don't delete console window namespaces too early
If the console finishes displaying its output and is "done" but
needs to draw a scrollbar to show the final output messages it
is possible for Tk to delete the window namespace before it does
the text widget updates, which means we are unable to add the
horizontal or vertical scrollbar to the window when the text
widget decides it cannot draw all glyphs on screen.

We need to delay deleting the window namespace until we know
the window is not going to ever be used again.  This occurs if
we are done receiving output, the command is successful and the
window is closed, or if the window is open and the user chooses
to close the window after the command has completed.

85f77eadcc git-gui: Copy objects/info/alternates during standard clone
If the source repository is using an objects/info/alternates file
we need to copy the file to our new repository so that it can access
any objects that won't be copied/hardlinked as they are stored in the
alternate location.

We explicitly resolve all paths in the objects/info/alternates as
relative to the source repository but then convert them into an
absolute path for the new clone.  This allows the new clone to
access the exact same locaton as the source repository, even if
relative paths had been used before.

Under Cygwin we assume that Git is Cygwin based and that the paths
in objects/info/alternates must be valid Cygwin UNIX paths, so we
need to run `cygpath --unix` on each line in the alternate list.

81d4d3dddc git-gui: Keep the UI responsive while counting objects in clone
If we are doing a "standard" clone by way of hardlinking the
objects (or copying them if hardlinks are not available) the
UI can freeze up for a good few seconds while Tcl scans all

Windows system when you are working off network shares and
need to wait for both the NT overheads and the network.

We now show a progress bar as we count the objects and build
our list of things to copy.  This keeps the user amused and
also makes sure we run the Tk event loop often enough that
the window can still be dragged around the desktop.

ab08b36304 git-gui: Allow users to choose/create/clone a repository
If we are started outside of a git repository than it is likely
the user started us from some sort of desktop shortcut icon in
the operating system.  In such a case the user is expecting us to
prompt them to locate the git repository they want to work on,
or to help them make a new repository, or to clone one from an
existing location.  This is a very simple wizard that offers the
user one of these three choices.

When we clone a repository we always use the name `master` in the
local repository, even if the remote side does not appear to point
to that name.  I chose this as a policy decision.  Much of the Git
documentation talks about `master` being the default branch in a
repository and that's what git-init does too.  If the remote side
doesn't call its default branch `master` most users just don't care,
they just want to use Git the way the documentation describes.

Rather than relying on the git-clone Porcelain that ships with
git we build the new repository ourselves and then obtain content
by git-fetch.  This technique simplifies the entire clone process
to roughly: `git init && git fetch && git pull`.  Today we use
three passes with git-fetch; the first pass gets us the bulk of
the objects and the branches, the second pass gets us the tags,
and the final pass gets us the current value of HEAD to initialize
the default branch.

If the source repository is on the local disk we try to use a
hardlink to connect the objects into the new clone as this can
be many times faster than copying the objects or packing them and
passing the data through a pipe to index-pack.  Unlike git-clone
we stick to pure Tcl [file link -hard] operation thus avoiding the
need to fork a cpio process to setup the hardlinks.  If hardlinks
do not appear to be supported (e.g. filesystem doesn't allow them or
we are crossing filesystem boundaries) we use file copying instead.

3849bfba84 git-gui: Disable native platform text selection in "lists"
Sometimes we use a Tk text widget as though it were a listbox.
This happens typically when we want to show an icon to the left
of the text label or just when a text widget is generally a better
choice then the native listbox widget.

In these cases if we want the user to have control over the selection
we implement our own "in_sel" tag that shows the selected region
and we perform our own selection management in the background
via keybindings and mouse bindings.  In such uses we don't want
the user to be able to activate the native platform selection by
dragging their mouse through the text widget.  Doing so creates a
very confusing display and the user is left wondering what it may
mean to have two different types of selection in the same widget.

Tk doesn't allow us to delete the "sel" tag that it uses internally
to manage the native selection but it will allow us to make it
invisible by setting the tag to have the same display properties
as unselected text.  So long as we don't actually use the "sel"
tag for anything in code its effectively invisible.

31bb1d1b2d git-gui: Paper bag fix missing translated strings
The Tcl expression "[append [mc Foo] Bar]" does not return the string
"FooBar" after translation; instead it is setting the variable Foo to
the value Bar, or if Foo is already defined it is appending Bar onto
the end of it.  This is *not* what we wanted to have happen here.

Tcl's join function is actually the correct function but its default
joinStr argument is a single space.  Unfortunately all of our call
sites do not want an extra space added to their string.  So we need
a small wrapper function to make the call to join with an empty
join string.  In C this is (roughly) the job of the strcat function.
Since strcat is not yet used at the global level it is a reasonable
name to use here.

afe2098ddd git-gui: Font chooser to handle a large number of font families
Simon Sasburg noticed that on X11 if there are more fonts than can
fit in the height of the screen Tk's native tk_optionMenu does not
offer scroll arrows to the user and it is not possible to review
all choices or to select those that are off-screen.  On Mac OS X
the tk_optionMenu works properly but is awkward to navigate if the
list is long.

This is a rewrite of our font selection by providing a new modal
dialog that the user can launch from the git-gui Options panel.
The dialog offers the user a scrolling list of fonts in a pane.
An example text shows the user what the font looks like at the size
they have selected.  But I have to admit the example pane is less
than ideal.  For example in the case of our diff font we really
should show the user an example diff complete with our native diff
syntax coloring.

66c75a5c9f git-gui: Localize commit/author dates when displaying them
Currently the Git plumbing is not localized so it does not know how
to output weekday and month names that conform to the user's locale
preferences.  This doesn't fit with the rest of git-gui's UI as some
of our dates are formatted in Tcl and some are just read from the Git
plumbing so dates aren't consistently presented.

Since git-for-each-ref is presenting us formatted dates and it offers
no way to change that setting even in git 1.5.3.1 we need to first do
a parse of the text strings it produces, correct for timezones, then
reformat the timestamp using Tcl's formatting routines.

Not exactly what I wanted to do but it gets us consistently presented
date strings in areas like the blame viewer and the revision picker
mega-widget's tooltips.

Earlier when I rewrote the merge implementation for git-gui I broke
it such that the conflict markers for the "theirs" side of the hunk

the full SHA-1 to git-merge, instead of giving it the reference name
the user saw in the merge dialog.

I'd still like to resolve the SHA-1 upfront in git-gui and always use
that value throughout the merge, but I can't do that until we have a
full implementation of git-merge written in Tcl.  Until then its more
important that the conflict markers be useful to the end-user, so we
need to pass off the ref name and not the SHA-1 ID.

However by not loading the remote configuration we were crashing

to decide which refs/heads/ items were actually local heads.  We

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.

names that all have a common prefix.

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.

My earlier introduction of the GITGUI_BCK file (which saves the user's

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

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.

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.

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.

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.

7cf0442667 git-gui: Option to default new branches to match tracking branches
In some workflows users will want to almost always just create a new
local branch that matches a remote branch.  In this type of workflow
it is handy to have the new branch dialog default to "Match Tracking
Branch" and "Starting Revision"-Tracking Branch", with the focus in
the branch filter field.  This can save users working on this type
of workflow at least two mouse clicks every time they create a new
local branch or switch to one with a fast-forward.

560eddc00c git-gui: Sort tags descending by tagger date
When trying to create a branch from a tag most people are looking
for a recent tag, not one that is ancient history.  Rather than
sorting tags by their string we now sort them by taggerdate, as
this places the recent tags at the top of the list and the very
old ones at the end.  Tag date works nicely as an approximation
of the actual history order of commits.

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.

dd87efc8cc git-gui: Allow users to match remote branch names locally
Some workflows have users create a local branch that matches a remote
branch they have fetched from another repository.  If the user wants
to push their changes back to that remote repository then they probably
want to use the same branch name locally so that git-gui's push dialog
can setup the push refspec automatically.

To prevent typos with the local branch name we now offer an option to
use the remote tracking branch name as the new local branch name.

name to match the remote branch name, so that the existing push
dialog can push the branch back up to the remote repository without
needing to do any sort of remapping.  To do that we need to know
exactly what branch name the remote system is using.

So all_tracking_branches returns a list of specifications, where
each specification is itself a list of:

  - remote name (repository we fetch from)
  - remote ref name (source ref we fetch from)

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.

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

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).

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.

fc816d7b85 git-gui: Rename fields in blame viewer to better descriptions
Calling the commit message pane $w_cmit is a tad confusing when

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.

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

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

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.

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.

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.

22c6769d91 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.

982cf98fa4 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.

d0b741dc08 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.

223475a77c 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.

aa252f194b git-gui: Allow users to delete remote branches
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.

61f82ce79a git-gui: Allow users to rename branches through 'branch -m'
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.

5b6ffff644 git-gui: GUI support for running 'git remote prune <name>'
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).

because the data for multiple viewers was all crammed into
a single pair of Tcl arrays.  This made the code hard to
read and even harder to maintain.

Now that we have a slightly better way of tracking the data
for our "meta-widgets" we can make use of it here in the
blame viewer to cleanup the code and make it easier to work
with long term.

28bf928cf8 git-gui: Don't attempt to inline array reads in methods
If a variable reference to a field is to an array, and it is
the only reference to that field in that method we cannot make
it an inlined [set foo] call as the regexp was converting the
Tcl code wrong.  We were producing "[set foo](x)" for "$foo(x)",
and that isn't valid Tcl when foo is an array.  So we just punt
if the only occurance has a ( after it.

c74b6c66f0 git-gui: Convert browser, console to "class" format
Now that we have a slightly easier method of working with per-widget
data we should make use of that technique in our browser and console
meta-widgets, as both have a decent amount of information that they
store on a per-widget basis and our current approach of handling
it is difficult to follow.

1f07c4e5ce git-gui: Define a simple class/method system
As most of the git-gui interface is based upon "meta-widgets"
that need to carry around a good deal of state (e.g. console
windows, browser windows, blame viewer) we have a good deal
of messy code that tries to store this meta-widget state in
global arrays, where keys into the array are formed from a
union of a unique "object instance id" and the field name.

This is a simple class system for Tcl that allows us to
hide much of that mess by making Tcl do what it does best;
process strings to manipulate its own code during startup.

Each object instance is placed into its own namespace.  The
namespace is created when the object instance is created and
the namespace is destroyed when the object instance is removed
from the system.  Within that namespace we place variables for
each field within the class; these variables can themselves be
scalar values or full-blown Tcl arrays.

A simple class might be defined as:

  class map {
    field data
    field size 0

    constructor {} {
      return $this
    }
    method set {name value} {
      set data($name) $value
      incr size
    }
    method size {} {
      return $size
    } ifdeleted { return 0 }
  }

All fields must be declared before any constructors or methods.  This
allows our class to generate a list of the fields so it can properly
alter the definition of the constructor and method bodies prior to
passing them off to Tcl for definition with proc. A field may optionally
be given a default/initial value.  This can only be done for non-array
type fields.

Constructors are given full access to all fields of the class, so they
can initialize the data values.  The default values of fields (if any)
are set before the constructor runs, and the implicit local variable
$this is initialized to the instance identifier.

Methods are given access to fields they actually use in their body.
Every method has an implicit "this" argument inserted as its first
parameter; callers of methods must be sure they supply this value.

Some basic optimization tricks are performed (but not much).  We
try to only upvar (locally bind) fields that are accessed within a
method, but we err on the side of caution and may upvar more than
we need to.  If a variable is accessed only once within a method
and that access is by $foo (read) we avoid the upvar and instead
use [set foo] to obtain the value.  This is slightly faster as Tcl
does not need to lookup the variable twice.

We also offer some small syntatic sugar for interacting with Tk and
the fileevent callback system in Tcl.  If a field (say "foo") is used
as "@foo" we insert instead the true global variable name of that
variable into the body of the constructor or method.  This allows easy
binding to Tk textvariable options, e.g.:

  label $w.title -textvariable @title

Proper namespace callbacks can also be setup with the special cb proc
that is defined in each namespace.  [cb _foo a] will invoke the method
_foo in the current namespace, passing it $this as the first (implied)
parameter and a as the second parameter.  This makes it very simple to
connect an object instance to a -command option for a Tk widget or to
a fileevent readable or writable for a file channel.

cc1f83fbdf git-gui: Allow shift-{k,j} to select a range of branches to merge
I found it useful to be able to use j/k (vi-like keys) to move
up and down the list of branches to merge and shift-j/k to do
the selection, much as shift-up/down (arrow keys) would alter
the selection.

ebcaadabcb git-gui: Use vi-like keys in merge dialog
Since we support vi-like keys for scrolling in other UI contexts
we can easily do so here too.  Tk's handy little `event generate'
makes this a lot easier than I thought it would be.  We may want
to go back and fix some of the other vi-like bindings to redirect
to the arrow and pageup/pagedown keys, rather than running the
view changes directly.

I've bound 'v' to visualize, as this is a somewhat common thing
to want to do in the merge dialog.  Control (or Command) Return
is also bound to start the merge, much as it is bound in the
main window to activate the commit.

1fc4ba86f8 git-gui: Include commit id/subject in merge choices
When merging branches using our local merge feature it can be
handy to know the first few digits of the commit the ref points
at as well as the short description of the branch name.

Unfortunately I'm unable to use three listboxes in a row, as Tcl
freaks out and refuses to let me have a selection in more than
one of them at any given point in time.  So instead we use a
fixed width font in the existing listbox and organize the data
into three columns.  Not nearly as nice looking, but users can
continue to use the listbox's features.

349f92e3a2 git-gui: Show all possible branches for merge
Johannes Sixt pointed out that git-gui was randomly selecting
which branch (or tag!) it will show in the merge dialog when
more than one ref points at the same commit.  This can be a
problem for the user if they want to merge a branch, but the
ref that git-gui selected to display was actually a tag that
points at the commit at the tip of that branch.  Since the
user is looking for the branch, and not the tag, its confusing
to not find it, and worse, merging the tag causes git-merge to
generate a different message than if the branch was selected.

While I am in here and am messing around I have changed the
for-each-ref usage to take advantage of its --tcl formatting,
and to fetch the subject line of the commit (or tag) we are
looking at.  This way we could present the subject line in the
UI to the user, given them an even better chance to select
the correct branch.

these aren't bound to anything else and that widget does not

a35d65d9c8 git-gui: Move console procs into their own namespace
To help modularize git-gui better I'm isolating the code and
variables required to handle our little console windows into
their own namespace.  This way we can say console::new rather
than new_console, and the hidden internal procs to create the
window and read data from our filehandle are off in their own
private little land, where most users don't see them.

f522c9b5ed git-gui: Refactor into multiple files to save my sanity
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.

I haven't really made any functionality changes here, this is just a
huge migration of code from one file to many smaller files.  All of
the new changes are to setup the library path and install the library
files.
