Sometimes, people have only fetch access into a bare repository
that is used as a back-up location (or a distribution point) but
does not have a push access for networking reasons, e.g. one end
being behind a firewall, and updating the "current branch" in
such a case is perfectly fine.
This allows such a fetch without --update-head-ok, which is a
flag that should never be used by end users otherwise.

This removes the old is_bare_git_dir(const char *) to ask if a
directory, if it is a GIT_DIR, is a bare repository, and
replaces it with is_bare_repository(void *). The function looks
at core.bare configuration variable if exists but uses the old
heuristics: if it is ".git" or ends with "/.git", then it does
not look like a bare repository, otherwise it does.

The patches to prevent Porcelainish that require working tree
from doing any damage in a bare repository make a lot of sense,
and I want to make the is_bare_git_dir() function more reliable.
In order to allow the repository owner override the heuristic
implemented in is_bare_git_dir() if/when it misidentifies a
particular repository, it would make sense to introduce a new
configuration variable "[core] bare = true/false", and make
is_bare_git_dir() notice it.
The scripts would do a 'repo-config --bool --get core.bare' and
iff the command fails (i.e. there is no such variable in the
configuration file), it would use the heuristic implemented at
the script level [*1*].
However, setup_git_env() which is called a lot earlier than we
even read from the repository configuration currently makes a
call to is_bare_git_dir(), in order to change the default
setting for log_all_ref_updates. It somehow feels that this is
a hack.
By the way, [*1*] is another thing I hate about the current
config mechanism. "git-repo-config --get" does not know what
the possible configuration variables are, let alone what the
default values for them are. It allows us not to maintain a
centralized configuration table, which makes it easy to
introduce ad-hoc variables and gives a warm fuzzy feeling of
being modular, but my feeling is that it is turning out to be a
rather high price to pay for scripts.

With this patch, cvsimport will skip commits made
in the last 10 minutes. The recent-ness test is of
5 minutes + cvsps fuzz window (5 minutes default).
When working with a CVS repository that is in use,
importing commits that are too recent can lead to
partially incorrect trees. This is mainly due to
- Commits that are within the cvsps fuzz window may later
be found to have affected more files.
- When performing incremental imports, clock drift between
the systems may lead to skipped commits.
This commit helps keep incremental imports of in-use
CVS repositories sane.

This updates the way diffcore represents an unmerged pair

In order to make the generated tar files more friendly to users who
extract them as root using GNU tar and its implied -p option, change
the default umask to 002 and change the owner name and group name to
root. This ensures that a) the extracted files and directories are
not world-writable and b) that they belong to user and group root.
Before they would have been assigned to a user and/or group named
git if it existed. This also answers the question in the removed
comment: uid=0, gid=0, uname=root, gname=root is exactly what we
want.
Normal users who let tar apply their umask while extracting are
only affected if their umask allowed the world to change their
files (e.g. a umask of zero). This case is so unlikely and strange
that we don't need to support it.

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.

Blame currently displays the commit id which introduced a
block of one or more lines, the line numbers wrt the current
listing of the file and the file's line contents.
The commit id displayed is hyperlinked to the commit.
Currently the linenr links are hyperlinked to the same
commit id displayed to the left, which is _no_ different
than the block of lines displayed, since it is the _same
commit_ that is hyperlinked. And thus clicking on it leads
to the same state of the file for that chunk of
lines. I.e. data mining is not currently possible with
gitweb given a chunk of lines introduced by a commit.
This patch makes such data mining possible.
The line numbers are now hyperlinked to the parent of the
commit id of the block of lines. Furthermore they are
linked to the line where that block was introduced.
Thus clicking on a linenr link will show you the file's
line(s) state prior to the commit id you were viewing.
So clicking continually on a linenr link shows you how this
line and its line number changed over time, leading to the
initial commit where it was first introduced.
