A handful of test cases and a corner case bugfix for "git rm".
* jk/rm-removed-paths:
t3600: document failure of rm across symbolic links
t3600: test behavior of reverse-d/f conflict
rm: do not complain about d/f conflicts during deletion

If we used to have an index entry "d/f", but "d" has been
replaced by a non-directory entry, the user may still want
to run "git rm" to delete the stale index entry. They could
use "git rm --cached" to just touch the index, but "git rm"
should also work: we explicitly try to handle the case that
the file has already been removed from the working tree.
However, because unlinking "d/f" in this case will not yield
ENOENT, but rather ENOTDIR, we do not notice that the file
is already gone. Instead, we report it as an error.
The simple solution is to treat ENOTDIR in this case exactly
like ENOENT; all we want to know is whether the file is
already gone, and if a leading path is no longer a
directory, then by definition the sub-path is gone.

Currently, do_push() in push.c calls remote_get(), which gets the
configured remote for fetching and pushing. Replace this call with a
call to pushremote_get() instead, a new function that will return the
remote configured specifically for pushing. This function tries to
work with the string pushremote_name, before falling back to the
codepath of remote_get(). This patch has no visible impact, but
serves to enable future patches to introduce configuration variables
to set pushremote_name. For example, you can now do the following in
handle_config():
if (!strcmp(key, "remote.pushdefault"))
git_config_string(&pushremote_name, key, value);
Then, pushes will automatically go to the remote specified by
remote.pushdefault.

fast-export can fail because of some pruned-reference when importing a
mark file.
The problem happens in the following scenario:
$ git fast-export --export-marks=MARKS master
(rewrite master)
$ git prune
$ git fast-export --import-marks=MARKS master
This might fail if some references have been removed by prune
because some marks will refer to no longer existing commits.
git-fast-export will not need these objects anyway as they were no
longer reachable.
We still need to update last_numid so we don't change the mapping
between marks and objects for remote-helpers.
Unfortunately, the mark file should not be rewritten without lost marks
if no new objects has been exported, as we could lose track of the last
last_numid.

"git merge $(git rev-parse v1.8.2)" behaved quite differently from
"git merge v1.8.2" as if v1.8.2 were written as v1.8.2^0 and did
not pay much attention to the annotated tag payload.
This makes the code notice the type of the tag object, in addition
to the dwim_ref() based classification the current code uses
(i.e. the name appears in refs/tags/) to decide when to special
case merging of tags.

The user could have said "git merge $(git rev-parse v1.0.0)"; we
shouldn't mark it as "Merge commit '15999998fb...'" as the merge
name, even though such an invocation might be crazy.
We could even read the "tag " header from the tag object and replace
the object name the user gave us, but let's not lose the information
by doing so, at least not yet.

If we manage to clone a remote repository but run into an
error in the checkout, it is probably sane to leave the repo
directory in place. That lets the user examine the situation
without spending time to re-clone from the remote (which may
be a lengthy process).
Rather than try to convert each die() from the checkout code
path into an error(), we simply set a flag that tells the
"remove_junk" atexit function to print a helpful message and
leave the repo in place.
Note that the test added in this patch actually passes
without the code change. The reason is that the cleanup code
is buggy; we chdir into the working tree for the checkout,
but still may use relative paths to remove the directories
(which means if you cloned into "foo", we would accidentally
remove "foo" from the working tree!). There's no point in
fixing it now, since this patch means we will never try to
remove anything after the chdir, anyway.

When we fetch from a remote, we do a revision walk to make
sure that what we received is connected to our existing
history. We do not do the same check for clone, which should
be able to check that we received an intact history graph.
The upside of this patch is that it will make clone more
resilient against propagating repository corruption. The
downside is that we will now traverse "rev-list --objects
--all" down to the roots, which may take some time (it is
especially noticeable for a "--local --bare" clone).
Note that we need to adjust t5710, which tries to make such
a bogus clone. Rather than checking after the fact that our
clone is bogus, we can simplify it to just make sure "git
clone" reports failure.

When clone is populating the working tree, it ignores the
return status from unpack_trees; this means we may report a
successful clone, even when the checkout fails.
When checkout fails, we may want to leave the $GIT_DIR in
place, as it might be possible to recover the data through
further use of "git checkout" (e.g., if the checkout failed
due to a transient error, disk full, etc). However, we
already die on a number of other checkout-related errors, so
this patch follows that pattern.
In addition to marking a now-passing test, we need to adjust
t5710, which blindly assumed it could make bogus clones of
very deep alternates hierarchies. By using "--bare", we can
avoid it actually touching any objects.

Originally update-pre-post-images could assume that any whitespace
fixing will make the result only shorter by unexpanding runs of
leading SPs into HTs and removing trailing whitespaces at the end of
lines. Updating the post-image we read from the patch to match the
actual result can be performed in-place under this assumption.
These days, however, we have tab-in-indent (aka Python) rule whose
result can be longer than the original, and we do need to allocate
a larger buffer than the input and replace the result.
Fortunately the support for lengthening rewrite was already added
when we began supporting "match while ignoring whitespace
differences" mode in 86c91f91794c (git apply: option to ignore
whitespace differences, 2009-08-04). We only need to correctly
count the number of bytes necessary to hold the updated result and
tell the function to allocate a new buffer.

In checkout_paths() we do this
- for all updated items, call match_pathspec
- for all items, call match_pathspec (inside unmerge_cache)
- for all items, call match_pathspec (for showing "path .. is unmerged)
- for updated items, call match_pathspec and update paths
That's a lot of duplicate match_pathspec(s) and the function is not
exactly cheap to be called so many times, especially on large indexes.
This patch makes it call match_pathspec once per updated index entry,
save the result in ce_flags and reuse the results in the following
loops.
The changes in 0a1283b (checkout $tree $path: do not clobber local
changes in $path not in $tree - 2011-09-30) limit the affected paths
to ones we read from $tree. We do not do anything to other modified
entries in this case, so the "for all items" above could be modified
to "for all updated items". But..
The command's behavior now is modified slightly: unmerged entries that
match $path, but not updated by $tree, are now NOT touched. Although
this should be considered a bug fix, not a regression. A new test is
added for this change.
And while at there, free ps_matched after use.
The following command is tested on webkit, 215k entries. The pattern
is chosen mainly to make match_pathspec sweat:
git checkout -- "*[a-zA-Z]*[a-zA-Z]*[a-zA-Z]*"

Commit ba3c69a9 (commit: teach --gpg-sign option, 2011-10-05) added the
-S option but documented it in the command usage without indicating that
the value is optional and forgot to mention it in the manpage. Later
commit 098bbdc3 (Add -S, --gpg-sign option to manpage of "git commit",
2012-10-21) documented the option in the porcelain manpage.
Use wording from the porcelain manpage to document the option in the
plumbing manpage. Also update the commit-tree usage summary to indicate
that the -S value is optional to be consistent with the manpage and with
the implementation.

The threaded parts of index-pack increment the number of resolved
deltas in nr_resolved_deltas guarded by counter_mutex. However, the
per-thread outer loop accessed nr_resolved_deltas without any locks.
This is not wrong as such, since it doesn't matter all that much
whether we get an outdated value. However, unless someone proves that
this one lock makes all the performance difference, it would be much
cleaner to guard _all_ accesses to the variable with the lock.
The only such use is display_progress() in the threaded section (all
others are in the conclude_pack() callchain outside the threaded
part). To make it obvious that it cannot deadlock, move it out of
work_mutex.

deepest_delta is a global variable but is updated without protection
in resolve_delta(), a multithreaded function. Add a new mutex for it,
but only protect and update when it's actually used (i.e. show_stat is
non-zero).
Another variable that will not be updated is delta_depth in "struct
object_entry" as it's only useful when show_stat is 1. Putting it in
"if (show_stat)" makes it clearer.
The local variable "stat" is renamed to "show_stat" after moving to
global scope because the name "stat" conflicts with stat(2) syscall.

Commit 38a4556 (index-pack: start learning to emulate
"verify-pack -v", 2011-06-03) added a "delta_depth" counter
to each "struct object_entry". Initially, all object entries
have their depth set to 0; in resolve_delta, we then set the
depth of each delta to "base + 1". Base entries never have
their depth touched, and remain at 0.
To ensure that all depths start at 0, that commit changed
calls to xmalloc the object_entry list into calls to
xcalloc. However, it forgot that we grow the list with
xrealloc later. These extra entries are used when we add an
object from elsewhere to complete a thin pack. If we add a
non-delta object, its depth value will just be uninitialized
heap data.
This patch fixes it by zero-initializing entries we add to
the objects list via the xrealloc.

Most of the callers of packet_read_line just read into a
static 1000-byte buffer (callers which handle arbitrary
binary data already use LARGE_PACKET_MAX). This works fine
in practice, because:
1. The only variable-sized data in these lines is a ref
name, and refs tend to be a lot shorter than 1000
characters.
2. When sending ref lines, git-core always limits itself
to 1000 byte packets.
However, the only limit given in the protocol specification
in Documentation/technical/protocol-common.txt is
LARGE_PACKET_MAX; the 1000 byte limit is mentioned only in
pack-protocol.txt, and then only describing what we write,
not as a specific limit for readers.
This patch lets us bump the 1000-byte limit to
LARGE_PACKET_MAX. Even though git-core will never write a
packet where this makes a difference, there are two good
reasons to do this:
1. Other git implementations may have followed
protocol-common.txt and used a larger maximum size. We
don't bump into it in practice because it would involve
very long ref names.
2. We may want to increase the 1000-byte limit one day.
Since packets are transferred before any capabilities,
it's difficult to do this in a backwards-compatible
way. But if we bump the size of buffer the readers can
handle, eventually older versions of git will be
obsolete enough that we can justify bumping the
writers, as well. We don't have plans to do this
anytime soon, but there is no reason not to start the
clock ticking now.
Just bumping all of the reading bufs to LARGE_PACKET_MAX
would waste memory. Instead, since most readers just read
into a temporary buffer anyway, let's provide a single
static buffer that all callers can use. We can further wrap
this detail away by having the packet_read_line wrapper just
use the buffer transparently and return a pointer to the
static storage. That covers most of the cases, and the
remaining ones already read into their own LARGE_PACKET_MAX
buffers.

The packets sent during ref negotiation are all terminated
by newline; even though the code to chomp these newlines is
short, we end up doing it in a lot of places.
This patch teaches packet_read_line to auto-chomp the
trailing newline; this lets us get rid of a lot of inline
chomping code.
As a result, some call-sites which are not reading
line-oriented data (e.g., when reading chunks of packfiles
alongside sideband) transition away from packet_read_line to
the generic packet_read interface. This patch converts all
of the existing callsites.
Since the function signature of packet_read_line does not
change (but its behavior does), there is a possibility of
new callsites being introduced in later commits, silently
introducing an incompatibility. However, since a later
patch in this series will change the signature, such a
commit would have to be merged directly into this commit,
not to the tip of the series; we can therefore ignore the
issue.
This is an internal cleanup and should produce no change of
behavior in the normal case. However, there is one corner
case to note. Callers of packet_read_line have never been
able to tell the difference between a flush packet ("0000")
and an empty packet ("0004"), as both cause packet_read_line
to return a length of 0. Readers treat them identically,
even though Documentation/technical/protocol-common.txt says
we must not; it also says that implementations should not
send an empty pkt-line.
By stripping out the newline before the result gets to the
caller, we will now treat the newline-only packet ("0005\n")
the same as an empty packet, which in turn gets treated like
a flush packet. In practice this doesn't matter, as neither
empty nor newline-only packets are part of git's protocols
(at least not for the line-oriented bits, and readers who
are not expecting line-oriented packets will be calling
packet_read directly, anyway). But even if we do decide to
care about the distinction later, it is orthogonal to this
patch. The right place to tighten would be to stop treating
empty packets as flush packets, and this change does not
make doing so any harder.

This is just write_or_die by another name. The one
distinction is that write_or_die will treat EPIPE specially
by suppressing error messages. That's fine, as we die by
SIGPIPE anyway (and in the off chance that it is disabled,
write_or_die will simulate it).

The current parsing scheme for upload-archive is to pack
arguments into a fixed-size buffer, separated by NULs, and
put a pointer to each argument in the buffer into a
fixed-size argv array.
This works fine, and the limits are high enough that nobody
reasonable is going to hit them, but it makes the code hard
to follow. Instead, let's just stuff the arguments into an
argv_array, which is much simpler. That lifts the "all
arguments must fit inside 4K together" limit.
We could also trivially lift the MAX_ARGS limitation (in
fact, we have to keep extra code to enforce it). But that
would mean a client could force us to allocate an arbitrary
amount of memory simply by sending us "argument" lines. By
limiting the MAX_ARGS, we limit an attacker to about 4
megabytes (64 times a maximum 64K packet buffer). That may
sound like a lot compared to the 4K limit, but it's not a
big deal compared to what git-archive will actually allocate
while working (e.g., to load blobs into memory). The
important thing is that it is bounded.
