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.

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.

Now that we only support merging one branch we can offer the user
a better user interface experience by allowing them to select the

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.

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.

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
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.

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

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

I totally missed this obvious optimization in the checkout code path.
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

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

to be supporting more in the future. Rather than keep editing this

In both the ff and reset merge_types supported by checkout_op the
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.

I've decided to teach checkout_op how to perform more than just a
fast-forward and reset type of merge. This way we can also do a full

computed during the ff/reset/fail decision process, in case we need
it later on when we actually start a true merge operation.

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.

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.

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

Sometimes switching between branches can take more than a second or
two, in which case `git checkout` would normally have shown a small

We now do obtain that progress meter from read-tree -v and include

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
