Because git-gui is being shipped as a subproject of the main
Git project and will often have a different lifecycle than
the main Git project, we should ship our own version number
in the release tarball rather than relying on the main Git
version file.
Git's master Makefile will invoke our own with the target
dist-version, asking us to save off our GITGUI_VERSION value
into our own version file, so that our GIT-VERSION-GEN script
can recover it at build time.

I'm stealing the exact logic used by core Git within its own Makefile to
setup the version number within scripts and executables. This way we
can be sure that the version number is always updated after a commit,
and that the version number also reflects when it is coming from a dirty
working directory (and is thus pretty worthless).

It might be handy to have a single command that helps you manage
your configuration that relates to downloading from remote
repositories. This currently does only about 20% of what I want
it to do.
$ git remote
shows the list of 'remotes' you have defined somewhere, and
$ git remote origin
shows the details about the named remote (in this case
"origin"). How the branches are tracked, if you have a
tracking branch that is stale, etc.
$ git add another git://git.kernel.org/pub/...
defines the default remote.another.url and remote.another.fetch
entries just like a clone does; you can say "git fetch another"
afterwards.
For it to be useful, I think it should be enhanced to:
- check overlaps of tracking branches and warn;
- offer to remove stale tracking branches in one go;
- offer ways to remove or rename remote;
- offer ways to update an existing remote, perhaps have an
interactive mode;
Other enhancements might be also possible, but I do not think of
anything that is absolutely necessary other than the above right
now.

Many users have noticed that core.filemode doesn't appear to be
automatically set right on Cygwin when using a repository stored
on NTFS. The issue is that Cygwin and NTFS correctly supports
the executable mode bit, and Git properly detected that, but most
native Windows applications tend to create files such that Cygwin
sees the executable bit set when it probably shouldn't be.
This is especially bad if the user's favorite editor deletes the
file then recreates it whenever they save (vs. just overwriting)
as now a file that was created with mode 0644 by checkout-index
appears to have mode 0755.
So we introduce NO_TRUSTABLE_FILEMODE, settable at compile time.
Setting this option forces core.filemode to false, even if the
detection code would have returned true. This option should be
enabled by default on Cygwin.

to reflog's expire subcommand can be chosen by the user by setting
configuration options in .git/config (or ~/.gitconfig), as users may
want different expiration windows for each repository but shouldn't

This prepares a place to collect reflog management subcommands,
and implements "expire" action.
$ git reflog expire --dry-run \
--expire=4.weeks \
--expire-unreachable=1.week \
refs/heads/master
The expiration uses two timestamps: --expire and --expire-unreachable.
Entries older than expire time (defaults to 90 days), and entries older
than expire-unreachable time (defaults to 30 days) and records a commit
that has been rewound and made unreachable from the current tip of the
ref are removed from the reflog.
The parameter handling is still rough, but I think the
core logic for expiration is already sound.

A script to be driven when the user says "git add --interactive"
is introduced.
When it is run, first it runs its internal 'status' command to
show the current status, and then goes into its internactive
command loop.
The command loop shows the list of subcommands available, and
gives a prompt "What now> ". In general, when the prompt ends
with a single '>', you can pick only one of the choices given
and type return, like this:
*** Commands ***
1: status 2: update 3: revert 4: add untracked
5: patch 6: diff 7: quit 8: help
What now> 1
You also could say "s" or "sta" or "status" above as long as the
choice is unique.
The main command loop has 6 subcommands (plus help and quit).
* 'status' shows the change between HEAD and index (i.e. what
will be committed if you say "git commit"), and between index
and working tree files (i.e. what you could stage further
before "git commit" using "git-add") for each path. A sample
output looks like this:
staged unstaged path
1: binary nothing foo.png
2: +403/-35 +1/-1 git-add--interactive.perl
It shows that foo.png has differences from HEAD (but that is
binary so line count cannot be shown) and there is no
difference between indexed copy and the working tree
version (if the working tree version were also different,
'binary' would have been shown in place of 'nothing'). The
other file, git-add--interactive.perl, has 403 lines added
and 35 lines deleted if you commit what is in the index, but
working tree file has further modifications (one addition and
one deletion).
* 'update' shows the status information and gives prompt
"Update>>". When the prompt ends with double '>>', you can
make more than one selection, concatenated with whitespace or
comma. Also you can say ranges. E.g. "2-5 7,9" to choose
2,3,4,5,7,9 from the list. You can say '*' to choose
everything.
What you chose are then highlighted with '*', like this:
staged unstaged path
1: binary nothing foo.png
* 2: +403/-35 +1/-1 git-add--interactive.perl
To remove selection, prefix the input with - like this:
Update>> -2
After making the selection, answer with an empty line to
stage the contents of working tree files for selected paths
in the index.
* 'revert' has a very similar UI to 'update', and the staged
information for selected paths are reverted to that of the
HEAD version. Reverting new paths makes them untracked.
* 'add untracked' has a very similar UI to 'update' and
'revert', and lets you add untracked paths to the index.
* 'patch' lets you choose one path out of 'status' like
selection. After choosing the path, it presents diff between
the index and the working tree file and asks you if you want
to stage the change of each hunk. You can say:
y - add the change from that hunk to index
n - do not add the change from that hunk to index
a - add the change from that hunk and all the rest to index
d - do not the change from that hunk nor any of the rest to index
j - do not decide on this hunk now, and view the next
undecided hunk
J - do not decide on this hunk now, and view the next hunk
k - do not decide on this hunk now, and view the previous
undecided hunk
K - do not decide on this hunk now, and view the previous hunk
After deciding the fate for all hunks, if there is any hunk
that was chosen, the index is updated with the selected hunks.
* 'diff' lets you review what will be committed (i.e. between
HEAD and index).
This is still rough, but does everything except a few things I
think are needed.
* 'patch' should be able to allow splitting a hunk into
multiple hunks.
* 'patch' does not adjust the line offsets @@ -k,l +m,n @@
in the hunk header. This does not have major problem in
practice, but it _should_ do the adjustment.
* It does not have any explicit support for a merge in
progress; it may not work at all.

The Cygwin folks have done a fine job at creating a POSIX layer
on Windows That Just Works(tm). However it comes with a penalty;
accessing files in the working tree by way of stat/open/mmap can
be slower for diffcore than inflating the data from a blob which
is stored in a packfile.
This performance problem is especially an issue in merge-recursive
when dealing with nearly 7000 added files, as we are loading
each file's content from the working directory to perform rename
detection. I have literally seen (and sadly watched) paint dry in
less time than it takes for merge-recursive to finish such a merge.
On the other hand this very same merge runs very fast on Solaris.
If Git is compiled with NO_FAST_WORKING_DIRECTORY set then we will
avoid looking at the working directory when the blob in question
is available within a packfile and the caller doesn't need the data
unpacked into a temporary file.
We don't use loose objects as they have the same open/mmap/close
costs as the working directory file access, but have the additional
CPU overhead of needing to inflate the content before use. So it
is still faster to use the working tree file over the loose object.
If the caller needs the file data unpacked into a temporary file
its likely because they are going to call an external diff program,
passing the file as a parameter. In this case reusing the working
tree file will be faster as we don't need to inflate the data and
write it out to a temporary file.
The NO_FAST_WORKING_DIRECTORY feature is enabled by default on
Cygwin, as that is the platform which currently appears to benefit
the most from this option.

This new function implements the functionality of RCS merge, but
in-memory. It returns < 0 on error, otherwise the number of conflicts.
Finding the conflicting lines can be a very expensive task. You can
control the eagerness of this algorithm:
- a level value of 0 means that all overlapping changes are treated
as conflicts,
- a value of 1 means that if the overlapping changes are identical,
it is not treated as a conflict.
- If you set level to 2, overlapping changes will be analyzed, so that
almost identical changes will not result in huge conflicts. Rather,
only the conflicting lines will be shown inside conflict markers.
With each increasing level, the algorithm gets slower, but more accurate.
Note that the code for level 2 depends on the simple definition of
mmfile_t specific to git, and therefore it will be harder to port that
to LibXDiff.

A shallow commit is a commit which has parents, which in turn are
"grafted away", i.e. the commit appears as if it were a root.
Since these shallow commits should not be edited by the user, but
only by core git, they are recorded in the file $GIT_DIR/shallow.
A repository containing shallow commits is called shallow.
The advantage of a shallow repository is that even if the upstream
contains lots of history, your local (shallow) repository needs not
occupy much disk space.
The disadvantage is that you might miss a merge base when pulling
