Move 'unpack_trees()' over to 'traverse_trees()' interface
This not only deletes more code than it adds, it gets rid of a
singularly hard-to-understand function (unpack_trees_rec()), and
replaces it with a set of smaller and simpler functions that use the
generic tree traversal mechanism to walk over one or more git trees in
parallel.
It's still not the most wonderful interface, and by no means is the new
code easy to understand either, but it's at least a bit less opaque.

Make 'traverse_trees()' traverse conflicting DF entries in parallel
This makes the traverse_trees() entry comparator routine use the more
relaxed form of name comparison that considers files and directories
with the same name identical.
We pass in a separate mask for just the directory entries, so that the
callback routine can decide (if it wants to) to only handle one or the
other type, but generally most (all?) users are expected to really want
to see the case of a name 'foo' showing up in one tree as a file and in
another as a directory at the same time.
In particular, moving 'unpack_trees()' over to use this tree traversal
mechanism requires this.

Make 'traverse_tree()' use linked structure rather than 'const char *base'
This makes the calling convention a bit less obvious, but a lot more
flexible. Instead of allocating and extending a new 'base' string, we
just link the top-most name into a linked list of the 'info' structure
when traversing a subdirectory, and we can generate the basename by
following the list.
Perhaps even more importantly, the linked list of info structures also
gives us a place to naturally save off other information than just the
directory name.

This new helper is identical to base_name_compare(), except it compares
conflicting directory/file entries as equal in order to help handling DF
conflicts (thus the name).
Note that while a directory name compares as equal to a regular file
with the new helper, they then individually compare _differently_ to a
filename that has a dot after the basename (because '\0' < '.' < '/').
So a directory called "foo/" will compare equal to a file "foo", even
though "foo.c" will compare after "foo" and before "foo/"
This will be used by routines that want to traverse the git namespace
but then handle conflicting entries together when possible.

When the rewriteRoot setting is used with git-svn, it causes the svn
IDs added to commit messages to bear a different URL than is actually
used to retrieve Subversion data.
It is common for Subversion repositories to be available multiple
ways: for instance, HTTP to the public, and svn+ssh to people with
commit access. The need to switch URLs for access is fairly common as
well -- perhaps someone was just given commit access. To switch URLs
without having to rewrite history, one can use the old url as a
rewriteRoot, and use the new one in the svn-remote url setting.
This works well for svn fetching and general git commands.
However, git-svn dcommit, rebase, and perhaps other commands do not
work in this scenario. They scan the svn ID lines in commit messages
and attempt to match them up with url lines in [svn-remote] sections
in the git config.
This patch allows them to match rewriteRoot options, if such options
are present.

get_pathspec(): die when an out-of-tree path is given
An earlier commit d089ebaa (setup: sanitize absolute and funny paths) made
get_pathspec() aware of absolute paths, but with a botched interface that
forced the callers to count the resulting pathspecs in order to detect
an error of giving a path that is outside the work tree.
This fixes it, by dying inside the function.
We had ls-tree test that relied on a misfeature in the original
implementation of its pathspec handling. Leading slashes were silently
removed from them. However we allow giving absolute pathnames (people
want to cut and paste from elsewhere) that are inside work tree these
days, so a pathspec that begin with slash _should_ be treated as a full
path. The test is adjusted to match the updated rule for get_pathspec().
Earlier I mistook three tests given by Robin that they should succeed, but
these are attempts to add path outside work tree, which should fail
loudly. These tests also have been fixed.
Instead of using "git-rev-list | git-diff-tree" pipeline for pickaxe
search, use git-log with appropriate options. Besides reducing number
of forks by one, this allows to use list form of open, which in turn
allow to not worry about quoting arguments and to avoid forking shell.
The options to git-log were chosen to reduce required changes in
pickaxe git command output parsing; gitweb still parses returned
commits one by one.
Parsing "pickaxe" output is simplified: git_search now reuses
parse_difftree_raw_line and writes affected files as they arrive using
the fact that commit name goes always before [raw] diff.
While at it long bug of pickaxe search was fixed, namely that the last
commit found by pickaxe search was never shown.

run-command: Redirect stderr to a pipe before redirecting stdout to stderr

This way if 'start_command' is called with a 'child_process'

then stderr will be redirected to a pipe before stdout is
redirected to stderr. So we can now get the process' stdout

before stderr was itself redirected, and therefore stdout
would not have followed stderr, which would not have been

Teach git mergetool to use custom commands defined at config time
Currently git mergetool is restricted to a set of commands defined
in the script. You can subvert the mergetool.<tool>.path to force
git mergetool to use a different command, but if you have a command
whose invocation syntax does not match one of the current tools then
you would have to write a wrapper script for it.
This patch adds two git config variable patterns which allow a more
flexible choice of merge tool.
If you run git mergetool with -t/--tool or the merge.tool config
variable set to an unrecognized tool then git mergetool will query the
mergetool.<tool>.cmd config variable. If this variable exists, then git
mergetool will treat the specified tool as a custom command and will use
a shell eval to run the command with the documented shell variables set.
mergetool.<tool>.trustExitCode can be used to indicate that the exit
code of the custom command can be used to determine the success of the

The new option --rebasing is used internally for rebase to tell am that

help "completion" scripts tell if the ongoing operation is am or rebase.
Also the option at the same time stands for --binary, -3 and -k which
are always given when rebase drives am as its backend.
Using the information "am" leaves, git-completion.bash tells ongoing
rebase and am apart.
It has been supported for a long time, but I do not think this feature has
been in use in the real world at all. We would eventually move this out
of the toplevel of the work tree and to somewhere under $GIT_DIR, so let's
remove the command line option to specify the location now.
am: read from the right mailbox when started from a subdirectory
An earlier commit c149184 (allow git-am to run in a subdirectory) taught
git-am to start from a subdirectory by going up to the root of the work
tree byitself, but it did not adjust the path to read the mbox from when
it did so.
ba002f3 (builtin-fsck: move common object checking code to fsck.c) did
more than what it claimed to. Most notably, it wrongly made an empty tree
object an error by pretending to only move code from fsck_tree() in
builtin-fsck.c to fsck_tree() in fsck.c, but in fact adding a bogus check
to barf on an empty tree.
An empty tree object is _unusual_. Recent porcelains try reasonably hard
not to let the user create a commit that contains such a tree. Perhaps
warning about them in git-fsck may have some merit.
HOWEVER.
Being unusual and being errorneous are two quite different things. This
is especially true now we seem to use the same fsck_$object() code in
places other than git-fsck itself. For example, receive-pack should not
reject unusual objects, even if it would be a good idea to tighten it to
reject incorrect ones.
Teach git-fetch to exploit server side automatic tag following
If the remote peer upload-pack process supports the include-tag
protocol extension then we can avoid running a second fetch cycle
on the client side by letting the server send us the annotated tags
along with the objects it is packing for us. In the following graph
we can now fetch both "tag1" and "tag2" on the same connection that
we fetched "master" from the remote when we only have L available
on the local side:
T - tag1 S - tag2
/ /
L - o ------ o ------ B
\ \
\ \
origin/master master
The objects for "tag1" are implicitly downloaded without our direct
knowledge. The existing "quickfetch" optimization within git-fetch
discovers that tag1 is complete after the first connection and does
not open a second connection.

can also include them in the packfile, saving the client from needing
to request them through a second connection.
This change only introduces the backend option and provides a test.

describe --always: fall back to showing an abbreviated object name
Some callers may find it useful if "git describe" always gave back a
string that can be used as a shorter name for a commit object, rather than
checking its exit status (while squelching its error message, which could
potentially talk about more grave errors that should not be squelched) and
implementing a fallback themselves.
This teaches describe/name-rev a new option, --always, to use an
abbreviated object name when no tags or refs to use is found.
Teach git-fetch to grab a tag at the same time as a commit
If the situation is the following on the remote and L is the common
base between both sides:
T - tag1 S - tag2
/ /
L - A - O - O - B
\ \
origin/master master
and we have decided to fetch "master" to acquire the range L..B we
can also nab tag S at the same time during the first connection,
as we can clearly see from the refs advertised by upload-pack that
S^{} = B and master = B.
Unfortunately we still cannot nab T at the same time as we are not
able to see that T^{} will also be in the range implied by L..B.
Such computations must be performed on the remote side (not yet
supported) or on the client side as post-processing (the current
behavior).
This optimization is an extension of the previous one in that it
helps on projects which tend to publish both a new commit and a
new tag, then lay idle for a while before publishing anything else.
Most followers are able to download both the new commit and the new
tag in one connection, rather than two. git.git tends to follow
such patterns with its roughly once-daily updates from Junio.
A protocol extension and additional server side logic would be
necessary to also ensure T is grabbed on the first connection.

Make git-fetch follow tags we already have objects for sooner
If autofollowing of tags is enabled, we see a new tag on the remote
that we don't have, and we already have the SHA-1 object that the
tag is peeled to, then we can fetch the tag while we are fetching
the other objects on the first connection.
This is a slight optimization for projects that have a habit of
tagging a release commit after most users have already seen and
downloaded that commit object through a prior fetch session. In
such cases the users may still find new objects in branch heads,
but the new tag will now also be part of the first pack transfer
and the subsequent connection to autofollow tags is not required.
Currently git.git does not benefit from this optimization as any
release usually gets a new commit at the same time that it gets a
new release tag, however git-gui.git and many other projects are
in the habit of tagging fairly old commits.
Users who did not already have the tagged commit still require
opening a second connection to autofollow the tag, as we are unable
to determine on the client side if $tag^{} will be sent to the
client during the first transfer or not. Such computation must be
performed on the remote side of the connection and is deferred to
another series of changes.

Teach upload-pack to log the received need lines to an fd
To facilitate testing and verification of the requests sent by
git-fetch to the remote side we permit logging the received packet
lines to the file descriptor specified in GIT_DEBUG_SEND_PACK has
been set. Special start and end lines are included to indicate
the start and end of each connection.
>From the above trace the first connection opened by git-fetch was to
download two refs (with values 8e and dd) and the second connection
was opened to automatically follow an annotated tag (32).
