441adf0ccf builtin-remote: make rm operation safer in mirrored repository
"git remote rm <repo>" happily removes non-remote refs and their reflogs.
This may be okay if the repository truely is a mirror, but if the user
had done "git remote add --mirror <repo>" by accident and was just
undoing their mistake, then they are left in a situation that is
difficult to recover from.

After this commit, "git remote rm" skips over non-remote refs. The user
is advised on how remove branches using "git branch -d", which itself
has nice safety checks wrt to branch removal lacking from "git remote rm".
Non-remote non-branch refs are skipped silently.

9273b56278 filter-branch: Fix fatal error on bare repositories
When git filter-branch is run on a bare repository, it prints out a fatal
error message:

  $ git filter-branch branch
  Rewrite 476c4839280c219c2317376b661d9d95c1727fc3 (9/9)
  WARNING: Ref 'refs/heads/branch' is unchanged
  fatal: This operation must be run in a work tree

Note that this fatal error message doesn't prevent git filter-branch from
exiting successfully. (Why doesn't git filter-branch actually exit with an
error when a shell command fails? I'm not sure why it was designed this
way.)

This error message is caused by the following section of code at the end of
git-filter-branch.sh:

  if [ "$(is_bare_repository)" = false ]; then
          unset GIT_DIR GIT_WORK_TREE GIT_INDEX_FILE
          test -z "$ORIG_GIT_DIR" || {
                  GIT_DIR="$ORIG_GIT_DIR" && export GIT_DIR
          }
          ... elided ...
          git read-tree -u -m HEAD
  fi

The problem is the call to $(is_bare_repository), which is made before
GIT_DIR and GIT_WORK_TREE are restored.  This call always returns "false",
even when we're running in a bare repository.  But this means that we will
attempt to call 'git read-tree' even in a bare repository, which will fail
and print an error.

This patch modifies git-filter-branch.sh to restore the original
environment variables before trying to call is_bare_repository.

c7cddc1a2f merge: fix out-of-bounds memory access
The parameter n of unpack_callback() can have a value of up to
MAX_UNPACK_TREES.  The check at the top of unpack_trees() (its only
(indirect) caller) makes sure it cannot exceed this limit.

unpack_callback() passes it and the array src to unpack_nondirectories(),
which has this loop:

	for (i = 0; i < n; i++) {
		/* ... */
		src[i + o->merge] = o->df_conflict_entry;

o->merge can be 0 or 1, so unpack_nondirectories() potentially accesses
the array src at index MAX_UNPACK_TREES.  This patch makes it big enough.

The size of the content we are adding may be larger than
2.1G (i.e., "git add gigantic-file"). Most of the code-path
to do so uses size_t or unsigned long to record the size,
but write_loose_object uses a signed int.

On platforms where "int" is 32-bits (which includes x86_64
Linux platforms), we end up passing malloc a negative size.

94c88edef7 Fix submodule squashing into unrelated commit
Actually, I think the issue is pretty independent of submodules; when
"git commit" gets an empty parameter, it misinterprets it as a file.

So avoid passing an empty parameter to "git commit".

Actually, this is a nice cleanup, as MSG_FILE and EDIT_COMMIT were mutually
exclusive; use one variable instead

Attempting to rebase three-commit series (two regular changes, followed by
one commit that changes what commit is bound for a submodule path) to
squash the first two results in a failure; not just the first two commits
squashed, but the change to the submodule is also included in the result.

This failure causes the subsequent step to "pick" the change that actually
changes the submodule to be applied, because there is no change left to be
applied.

d8e96fd86d git: use run_command() to execute dashed externals
We used to simply try calling execvp(); if it succeeded, then we were done
and the new program was running. If it didn't, then we knew that it wasn't
a valid command.

Unfortunately, this interacted badly with the new pager handling. Now that
git remains the parent process and the pager is spawned, git has to hang
around until the pager is finished. We install an atexit handler to do
this, but that handler never gets called if we successfully run execvp.

You could see this behavior by running any dashed external using a pager
(e.g., "git -p stash list"). The command finishes running, but the pager
is still going. In the case of less, it then gets an error reading from
the terminal and exits, potentially leaving the terminal in a broken state
(and not showing the output).

This patch just uses run_command() to try running the dashed external. The
parent git process then waits for the external process to complete and
then handles the pager cleanup as it would for an internal command.

error code or the exit status of the spawned program. The

magic limit, let's provide a macro.

45c0961c87 run_command(): handle missing command errors more gracefully
When run_command() was asked to run a non-existant command, its behavior
varied depending on the platform:

  - on POSIX systems, we would fork, and then after the execvp call
    failed, we could call die(), which prints a message to stderr and
    exits with code 128.

  - on Windows, we do a PATH lookup, realize the program isn't there, and
    then return ERR_RUN_COMMAND_FORK

The goal of this patch is to make it clear to callers that the specific
error was a missing command. To do this, we will return the error code
ERR_RUN_COMMAND_EXEC, which is already defined in run-command.h, checked
for in several places, but never actually gets set.

The new behavior is:

  - on POSIX systems, we exit the forked process with code 127 (the same
    as the shell uses to report missing commands). The parent process
    recognizes this code and returns an EXEC error. The stderr message is
    silenced, since the caller may be speculatively trying to run a
    command. Instead, we use trace_printf so that somebody interested in
    debugging can see the error that occured.

  - on Windows, we check errno, which is already set correctly by
    mingw_spawnvpe, and report an EXEC error instead of a FORK error

Thus it is safe to speculatively run a command:

  int r = run_command_v_opt(argv, 0);
  if (r == -ERR_RUN_COMMAND_EXEC)
	  /* oops, it wasn't found; try something else */
  else
	  /* we failed for some other reason, error is in r */

aeeae1b771 revision traversal: allow UNINTERESTING objects to be missing
Most of the existing codepaths were meant to treat missing uninteresting
objects to be a silently ignored non-error, but there were a few places
in handle_commit() and add_parents_to_list(), which are two key functions
in the revision traversal machinery, that cared:

 - When a tag refers to an object that we do not have, we barfed.  We
   ignore such a tag if it is painted as UNINTERESTING with this change.

 - When digging deeper into the ancestry chain of a commit that is already
   painted as UNINTERESTING, in order to paint its parents UNINTERESTING,
   we barfed if parse_parent() for a parent commit object failed.  We can
   ignore such a parent commit object.

02322e1619 send-pack: do not send unknown object name from ".have" to pack-objects
v1.6.1 introduced ".have" extension to the protocol to allow the receiving
side to advertise objects that are reachable from refs in the repositories
it borrows from.  This was meant to be used by the sending side to avoid
sending such objects; they are already available through the alternates
mechanism.

The client side implementation in v1.6.1, which was introduced with
40c155f (push: prepare sender to receive extended ref information from the
receiver, 2008-09-09) aka v1.6.1-rc1~203^2~1, were faulty in that it did
not consider the possiblity that the repository receiver borrows from
might have objects it does not know about.

This fixes it by refraining from passing missing commits to underlying
pack-objects.  Revision machinery may need to be tightened further to
treat missing uninteresting objects as non-error events, but this is an
obvious and safe fix for a maintenance release that is almost good enough.

b67b9612e1 diff.c: output correct index lines for a split diff
A patch that changes the filetype (e.g. regular file to symlink) of a path
must be split into a deletion event followed by a creation event, which
means that we need to have two independent metainfo lines for each.
However, the code reused the single set of metainfo lines.

As the blob object names recorded on the index lines are usually not used
nor validated on the receiving end, this is not an issue with normal use
of the resulting patch.  However, when accepting a binary patch to delete
a blob, git-apply verified that the postimage blob object name on the
index line is 0{40}, hence a patch that deletes a regular file blob that
records binary contents to create a blob with different filetype (e.g. a
symbolic link) failed to apply.  "git am -3" also uses the blob object
names recorded on the index line, so it would also misbehave when
synthesizing a preimage tree.

This moves the code to generate metainfo lines around, so that two
independent sets of metainfo lines are used for the split halves.

Additional tests by Jeff King.
