2d8ad46919 fast-export: Add a --tag-of-filtered-object option for newly dangling tags
When providing a list of paths to limit what is exported, the object that
a tag points to can be filtered out entirely.  This new switch allows
the user to specify what should happen to the tag in such a case.  The
default action, 'abort' will exit with an error message.  With 'drop', the
tag will simply be omitted from the output.  With 'rewrite', if the object
tagged was a commit, the tag will be modified to tag an alternate commit.
The alternate commit is determined by treating the original commit as the
"parent" of the tag and then using the parent rewriting algorithm of the
revision traversal machinery (related to the "--parents" option of "git
rev-list")

2374502c6c fast-export: Make sure we show actual ref names instead of "(null)"
The code expects a ref name to be provided in commit->util.  While there
was some code to set commit->util, it only worked in cases where there was
an unbroken chain of revisions from a ref to the relevant commit.  In
cases such as running
   git fast-export --parents master -- COPYING
commit->util would fail to be set.  The old method of setting commit->util
has been removed in favor of requesting show_source from the revision
traversal machinery (related to the "--source" option of "git log" family
of commands.)

However, this change does not fix cases like
   git fast export master~1
or
   git fast export :/arguments
since in such cases commit->util will be "master~1" or ":/arguments" while
we need the actual ref (e.g. "refs/heads/master")

02c48cd69b fast-export: Omit tags that tag trees
Commit c0582c53bc introduced logic to just
omit tags that point to tree objects.  However, these objects were still
being output and were pointing at "mark :0", which caused fast-import to
crash.  This patch makes sure such tags (including deeper nestings such
as tags of tags of trees), are omitted.

setup_revisions sets a variety of flags based on the setting of other

circumventing any invariants created by setup_revisions, we set

a437900fd7 attribute: whitespace set to true detects all errors known to git
That is what the documentation says, but the code pretends as if all the
known whitespace error tokens were given.

Among the whitespace error tokens, there is one kind that loosens the rule
when set: cr-at-eol.  Which means that whitespace error token that is set
to true ignores a newly introduced CR at the end, which is inconsistent
with the documentation.

e2f6331a14 .gitattributes: CR at the end of the line is an error
When a CR is accidentally added at the end of a C source file in the git
project tree, "git diff --check" doesn't detect it as an error.

    $ echo abQ | tr Q '\015' >>fast-import.c
    $ git diff --check

I think this is because the "whitespace" attribute is set to *.[ch] files
without specifying what kind of errors are caught. It makes git "notice
all types of errors" (as described in the documentation), but I think it
is incorrectly setting cr-at-eol, too, and hides this error.

2af202be3d Fix various sparse warnings in the git source code
There are a few remaining ones, but this fixes the trivial ones. It boils
down to two main issues that sparse complains about:

 - warning: Using plain integer as NULL pointer

   Sparse doesn't like you using '0' instead of 'NULL'. For various good
   reasons, not the least of which is just the visual confusion. A NULL
   pointer is not an integer, and that whole "0 works as NULL" is a
   historical accident and not very pretty.

   A few of these remain: zlib is a total mess, and Z_NULL is just a 0.
   I didn't touch those.

 - warning: symbol 'xyz' was not declared. Should it be static?

   Sparse wants to see declarations for any functions you export. A lack
   of a declaration tends to mean that you should either add one, or you
   should mark the function 'static' to show that it's in file scope.

   A few of these remain: I only did the ones that should obviously just
   be made static.

That 'wt_status_submodule_summary' one is debatable. It has a few related
flags (like 'wt_status_use_color') which _are_ declared, and are used by
builtin-commit.c. So maybe we'd like to export it at some point, but it's
not declared now, and not used outside of that file, so 'static' it is in
this patch.

cb8a9bd518 Test cccmd in t9001-send-email.sh and fix some bugs
For another patch series I'm working on I needed some tests
for the cc-cmd feature of git-send-email.

This patch adds 3 tests for the feature and for the possibility
to specify --suppress-cc multiple times, and fixes two bugs.
The first bug is that the --suppress-cc option for `cccmd' was
misspelled as `ccmd' in the code.  The second bug, which is
actually found only with my other series, is that the argument
to the cccmd is never quoted, so the cccmd would fail with
patch file names containing a space.

A third bug I fix (in the docs) is that the bodycc argument was
actually spelled ccbody in the documentation and bash completion.

1b19fa4634 upload-archive: fix infinite loop on Cygwin
On Cygwin, poll() reports POLLIN even for file descriptors that have
reached their end.  This caused git upload-archive to be stuck in an
infinite loop, as it only looked at the POLLIN flag.

In addition to POLLIN, check if read() returned 0, which indicates
end-of-file, and keep looping only as long as at least one of the file
descriptors has input.  This lets the following command finish on its
own when run in a git repository on Cygwin, instead of it getting stuck
after printing all file names:

	$ git archive -v --remote . HEAD >/dev/null

959e2e64a5 avoid exponential regex match for java and objc function names
In the old regex

^[ \t]*(([ \t]*[A-Za-z_][A-Za-z_0-9]*){2,}[ \t]*\([^;]*)$
        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

you can backtrack arbitrarily from [A-Za-z_0-9]* into [A-Za-z_], thus
causing an exponential number of backtracks.  Ironically it also causes
the regex not to work as intended; for example "catch" can match the
underlined part of the regex, the first repetition matching "c" and
the second matching "atch".

The replacement regex avoids this problem, because it makes sure that
at least a space/tab is eaten on each repetition.  In other words,
a suffix of a repetition can never be a prefix of the next repetition.

48fb7deb5b Fix big left-shifts of unsigned char
Shifting 'unsigned char' or 'unsigned short' left can result in sign
extension errors, since the C integer promotion rules means that the
unsigned char/short will get implicitly promoted to a signed 'int' due to
the shift (or due to other operations).

This normally doesn't matter, but if you shift things up sufficiently, it
will now set the sign bit in 'int', and a subsequent cast to a bigger type
(eg 'long' or 'unsigned long') will now sign-extend the value despite the
original expression being unsigned.

One example of this would be something like

	unsigned long size;
	unsigned char c;

	size += c << 24;

where despite all the variables being unsigned, 'c << 24' ends up being a
signed entity, and will get sign-extended when then doing the addition in
an 'unsigned long' type.

Since git uses 'unsigned char' pointers extensively, we actually have this
bug in a couple of places.

I may have missed some, but this is the result of looking at

	git grep '[^0-9 	][ 	]*<<[ 	][a-z]' -- '*.c' '*.h'
	git grep '<<[   ]*24'

which catches at least the common byte cases (shifting variables by a
variable amount, and shifting by 24 bits).

I also grepped for just 'unsigned char' variables in general, and
converted the ones that most obviously ended up getting implicitly cast
immediately anyway (eg hash_name(), encode_85()).

In addition to just avoiding 'unsigned char', this patch also tries to use
a common idiom for the delta header size thing. We had three different
variations on it: "& 0x7fUL" in one place (getting the sign extension
right), and "& ~0x80" and "& 0x7f" in two other places (not getting it
right). Apart from making them all just avoid using "unsigned char" at
all, I also unified them to then use a simple "& 0x7f".

I considered making a sparse extension which warns about doing implicit
casts from unsigned types to signed types, but it gets rather complex very
quickly, so this is just a hack.
