9d55b2e12f mailinfo: don't require "text" mime type for attachments
Currently "git am" does insane things if the mbox it is given contains
attachments with a MIME type that aren't "text/*".

In particular, it will still decode them, and pass them "one line at a
time" to the mail body filter, but because it has determined that they
aren't text (without actually looking at the contents, just at the mime
type) the "line" will be the encoding line (eg 'base64') rather than a
line of *content*.

Which then will cause the text filtering to fail, because we won't
correctly notice when the attachment text switches from the commit message
to the actual patch. Resulting in a patch failure, even if patch may be a
perfectly well-formed attachment, it's just that the message type may be
(for example) "application/octet-stream" instead of "text/plain".

Just remove all the bogus games with the message_type. The only difference
that code creates is how the data is passed to the filter function
(chunked per-pred-code line or per post-decode line), and that difference
is *wrong*, since chunking things per pre-decode line can never be a
sensible operation, and cannot possibly matter for binary data anyway.

This code goes all the way back to March of 2007, in commit 87ab799234
("builtin-mailinfo.c infrastrcture changes"), and apparently Don used to
pass random mbox contents to git. However, the pre-decode vs post-decode
logic really shouldn't matter even for that case, and more importantly, "I
fed git am crap" is not a valid reason to break *real* patch attachments.

If somebody really cares, and determines that some attachment is binary
data (by looking at the data, not the MIME-type), the whole attachment
should be dismissed, rather than fed in random-sized chunks to
"handle_filter()".

This incidentally fixes an unrelated problem on a case insensitive

8f6811efed commit: pay attention to submodule.$name.ignore in .gitmodules
"git status" does not list a submodule with uncommitted working tree
files as modified when "submodule.$name.ignore" is set to "dirty" in
in-tree ".gitmodules" file.  Both status and commit honor the setting
in $GIT_DIR/config, but "commit" does not pick it up from .gitmodules,
which is inconsistent.

Teach "git commit" to pay attention to the setting in .gitmodules as
well.

74eb32d3a4 receive-pack: drop "n/a" on unpacker errors
The output from git push currently looks like this:

  $ git push dest HEAD
  fatal: [some message from index-pack]
  error: unpack failed: index-pack abnormal exit
  To dest
   ! [remote rejected] HEAD -> master (n/a (unpacker error))

That n/a is meant to be "the per-ref status is not
available" but the nested parentheses just make it look
ugly. Let's turn the final line into just:

   ! [remote rejected] HEAD -> master (unpacker error)

a22e6f8547 receive-pack: send pack-processing stderr over sideband
Receive-pack invokes either unpack-objects or index-pack to
handle the incoming pack. However, we do not redirect the
stderr of the sub-processes at all, so it is never seen by
the client. From the initial thread adding sideband support,
which is here:

  http://thread.gmane.org/gmane.comp.version-control.git/139471

it is clear that some messages are specifically kept off the
sideband (with the assumption that they are of interest only
to an administrator, not the client). The stderr of the
subprocesses is mentioned in the thread, but it's unclear if
they are included in that group, or were simply forgotten.

However, there are a few good reasons to show them to the
client:

  1. In many cases, they are directly about the incoming
     packfile (e.g., fsck warnings with --strict, corruption
     in the packfile, etc). Without these messages, the
     client just gets "unpacker error" with no extra useful
     diagnosis.

  2. No matter what the cause, we are probably better off
     showing the errors to the client. If the client and the
     server admin are not the same entity, it is probably
     much easier for the client to cut-and-paste the errors
     they see than for the admin to try to dig them out of a
     log and correlate them with a particular session.

  3. Users of the ssh transport typically already see these
     stderr messages, as the remote's stderr is copied
     literally by ssh. This brings other transports (http,
     and push-over-git if you are crazy enough to enable it)
     more in line with ssh. As a bonus for ssh users,
     because the messages are now fed through the sideband
     and printed by the local git, they will have "remote:"
     prepended and be properly interleaved with any local
     output to stderr.

59bfdfb82a receive-pack: redirect unpack-objects stdout to /dev/null
The unpack-objects command should not generally produce any
output on stdout. However, if it's given extra input after
the packfile, it will spew the remainder to stdout. When
called by receive-pack, this means we will break protocol,
since our stdout is connected to the remote send-pack.

31b808a032 clone --single: limit the fetch refspec to fetched branch
After running "git clone --single", the resulting repository has the
usual default "+refs/heads/*:refs/remotes/origin/*" wildcard fetch
refspec installed, which means that a subsequent "git fetch" will
end up grabbing all the other branches.

Update the fetch refspec to cover only the singly cloned ref instead
to correct this.

That means:
If "--single" is used without "--branch" or "--mirror", the
fetch refspec covers the branch on which remote's HEAD points to.
If "--single" is used with "--branch", it'll cover only the branch
specified in the "--branch" option.
If "--single" is combined with "--mirror", then it'll cover all
refs of the cloned repository.
If "--single" is used with "--branch" that specifies a tag, then
it'll cover only the ref for this tag.

17bf35a3c7 grep: teach --debug option to dump the parse tree
Our "grep" allows complex boolean expressions to be formed to match
each individual line with operators like --and, '(', ')' and --not.
Introduce the "--debug" option to show the parse tree to help people
who want to debug and enhance it.

Also "log" learns "--grep-debug" option to do the same.  The command
line parser to the log family is a lot more limited than the general
"git grep" parser, but it has special handling for header matching
(e.g. "--author"), and a parse tree is valuable when working on it.

Note that "--all-match" is *not* any individual node in the parse
tree.  It is an instruction to the evaluator to check all the nodes
in the top-level backbone have matched and reject a document as
non-matching otherwise.

9aeaab6811 blame: allow "blame file" in the middle of a conflicted merge
"git blame file" has always meant "find the origin of each line of
the file in the history leading to HEAD, oh by the way, blame the
lines that are modified locally to the working tree".

This teaches "git blame" that during a conflicted merge, some
uncommitted changes may have come from the other history that is
being merged.

The verify_working_tree_path() function introduced in the previous
patch to notice a typo in the filename (primarily on case insensitive
filesystems) has been updated to allow a filename that does not exist
in HEAD (i.e. the tip of our history) as long as it exists one of the
commits being merged, so that a "we deleted, the other side modified"
case tracks the history of the file in the history of the other side.

ffcabccf5d blame $path: avoid getting fooled by case insensitive filesystems
"git blame MAKEFILE" run in a history that has "Makefile" but not
MAKEFILE can get confused on a case insensitive filesystem, because
the check we run to see if there is a corresponding file in the
working tree with lstat("MAKEFILE") succeeds.  In addition to that
check, we have to make sure that the given path also exists in the
commit we start digging history from (i.e. "HEAD").

Note that this reveals the breakage in a test added in cd8ae20
(git-blame shouldn't crash if run in an unmerged tree, 2007-10-18),
which expects the entire merge-in-progress path to be blamed to the
working tree when it did not exist in our tree.  As it is clear in
the log message of that commit, the old breakage was that it was
causing an internal error and the fix was about avoiding it.

Just check that the command does not die an uncontrolled death.  For
this particular case, the blame should fail, as the history for the
file in that contents has not been committed yet at the point in the
test.

which won't change during the iteration and copies the given options into
it. Inside the loop the two argv values different for each submodule get
replaced with those currently valid.

However, this technique is brittle and error-prone (as the comment to
explain the magic number 6 indicates), so let's replace it with an
argv_array. Instead of replacing the argv values, push them to the
argv_array just before the run_command() call (including the option
separating them) and pop them from the argv_array right after that.

85556d4e37 fetch: use argv_array instead of hand-building arrays
Fetch invokes itself recursively when recursing into
submodules or handling "fetch --multiple". In both cases, it
builds the child's command line by pushing options onto a
statically-sized array. In both cases, the array is
currently just big enough to handle the largest possible
case. However, this technique is brittle and error-prone, so
let's replace it with a dynamic argv_array.

e27ddb6456 split_ident_line(): make best effort when parsing author/committer line
Commits made by ancient version of Git allowed committer without
human readable name, like this (00213b17c in the kernel history):

    tree 6947dba41f8b0e7fe7bccd41a4840d6de6a27079

When fed such a commit, --format='%ci' fails to parse it, and gives
back an empty string.  Update the split_ident_line() to be a bit
more lenient when parsing, but make sure the caller that wants to
pick up sane value from its return value does its own validation.

a73e22e963 cherry-pick/revert: respect order of revisions to pick
When giving multiple individual revisions to cherry-pick or revert, as
in 'git cherry-pick A B' or 'git revert B A', one would expect them to
be picked/reverted in the order given on the command line. They are
instead ordered by their commit timestamp -- in chronological order
for "cherry-pick" and in reverse chronological order for
"revert". This matches the order in which one would usually give them
on the command line, making this bug somewhat hard to notice. Still,
it has been reported at least once before [1].

It seems like the chronological sorting happened by accident because
the revision walker has traditionally always sorted commits in reverse
chronological order when rev_info.no_walk was enabled. In the case of
'git revert B A' where B is newer than A, this sorting is a no-op. For
'git cherry-pick A B', the sorting would reverse the arguments, but
because the sequencer also flips the rev_info.reverse flag when
picking (as opposed to reverting), the end result is a chronological
order. The rev_info.reverse flag was probably flipped so that the
revision walker emits B before C in 'git cherry-pick A..C'; that it
happened to effectively undo the unexpected sorting done when not
walking, was probably a coincidence that allowed this bug to happen at
all.

Fix the bug by telling the revision walker not to sort the commits
when not walking. The only case we want to reverse the order is now
when cherry-picking and walking revisions (rev_info.no_walk = 0).

ca92e59e30 teach log --no-walk=unsorted, which avoids sorting
When 'git log' is passed the --no-walk option, no revision walk takes
place, naturally. Perhaps somewhat surprisingly, however, the provided
revisions still get sorted by commit date. So e.g 'git log --no-walk
HEAD HEAD~1' and 'git log --no-walk HEAD~1 HEAD' give the same result
(unless the two revisions share the commit date, in which case they
will retain the order given on the command line). As the commit that
introduced --no-walk (8e64006 (Teach revision machinery about
--no-walk, 2007-07-24)) points out, the sorting is intentional, to
allow things like

 git log --abbrev-commit --pretty=oneline --decorate --all --no-walk

to show all refs in order by commit date.

But there are also other cases where the sorting is not wanted, such
as

 <command producing revisions in order> |
       git log --oneline --no-walk --stdin

To accomodate both cases, leave the decision of whether or not to sort
up to the caller, by allowing --no-walk={sorted,unsorted}, defaulting
to 'sorted' for backward-compatibility reasons.
