This updates the way diffcore represents an unmerged pair
somewhat. It used to be that entries with mode=0 on both sides
were used to represent an unmerged pair, but now it has an
explicit flag. This is to allow diff-index --cached to report
the entry from the tree when the path is unmerged in the index.
This is used in updating "git reset <tree> -- <path>" to restore
absense of the path in the index from the tree.

Do not replace /dev/null in two-line from-file/to-file diff header for
split patches ("split" patch mean more than one patch per one
diff-tree raw line) by a/file or b/file link.
Split patches differ from pair of deletion/creation patch in git diff
header: both a/file and b/file are hyperlinks, in all patches in a
split.

empty means that they consist only of git diff header, and of extended

extended diff header there can be next patch (i.e. /^diff /) or end of

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.

If we have a 64 bit address space we can easily afford to commit
a larger amount of virtual address space to pack file access.
So on these platforms we should increase the default settings of

handle very large projects.
Thanks to Andy Whitcroft for pointing out that we can safely
increase these defaults on such systems.

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.

need to update the counter in the parent process to have a

The variable named entry is allocated using malloc() and then
forgotten, it being shadowed by an automatic variable of the
same name. Fixing the array size at 3 worked so far because
the only caller of traverse_trees() needed only as much
entries. Simply remove the shadowing varaible and we're able
to traverse more than three trees and save stack space at the

Running the SHA1_Update() on the whole packfile in a single call
revealed an overflow problem we had in the SHA-1 implementation
on POWER architecture some time ago, which was fixed with commit
b47f509b (June 19, 2006). Other SHA-1 implementations may have
a similar problem.
The sliding mmap() series already makes chunked calls to
SHA1_Update(), so this patch itself will become moot when it
graduates to "master", but in the meantime, run the hash
function in smaller chunks to prevent possible future problems.

It was stupid to link the same element twice to lock_file_list
and end up in a loop, so we certainly need a fix.
But it is not like we are taking a lock on multiple files in
this case. It is just that we leave the linked element on the
list even after commit_lock_file() successfully removes the
cruft.
We cannot remove the list element in commit_lock_file(); if we
are interrupted in the middle of list manipulation, the call to
remove_lock_file_on_signal() will happen with a broken list
structure pointed by lock_file_list, which would cause the cruft
to remain, so not removing the list element is the right thing
to do. Instead we should be reusing the element already on the
list.
There is already a code for that in lock_file() function in
lockfile.c. The code checks lk->next and the element is linked
only when it is not already on the list -- which is incorrect
for the last element on the list (which has NULL in its next
field), but if you read the check as "is this element already on
the list?" it actually makes sense. We do not want to link it
on the list again, nor we would want to set up signal/atexit
over and over.
