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.

0e987a12fc am, rebase: teach quiet option
git-am and git-rebase are talkative scripts. Teach them to be quiet when
told, allowing them to speak only when they fail or experience errors.

The quiet option is maintained when git-am or git-rebase fails to apply
a patch. This means subsequent --resolved, --continue, --skip, --abort
invocations will be quiet if the original invocation was quiet.

Drop a handful of >&2 redirection; the rest of the program sends all the

9462e3f59c upload-pack: squelch progress indicator if client cannot see it
upload-pack runs pack-objects, which generates progress indicator output
on its stderr. If the client requests a sideband, this indicator is sent
to the client; but if it did not, then the progress is written to
upload-pack's own stderr.

If upload-pack is itself run from git-daemon (and if the client did not
request a sideband) the progress indicator never reaches the client and it
need not be generated in the first place. With this patch the progress
indicator is suppressed in this situation.

5d87dd4fca daemon: send stderr of service programs to the syslog
If git-daemon is run with --detach or --inetd, then stderr is explicitly
redirected to /dev/null. But notice that the service programs were spawned
via execl_git_cmd(), in particular, the stderr channel is inherited from
the daemon. This means that errors that the programs wrote to stderr (for
example, via die()), went to /dev/null.

This patch arranges that the daemon does not merely exec the service
program, but forks it and monitors stderr of the child; it writes the
errors that it produces to the daemons log via logerror().

A consequence is that the daemon process remains in memory for the full
duration of the service program, but this cannot be avoided.

Add a configuration option, http.sslCertPasswordProtected, and associated
environment variable, GIT_SSL_CERT_PASSWORD_PROTECTED, to enable SSL client
certificate password prompt from within git.  If this option is false and
if the environment variable does not exist, git falls back to OpenSSL's
prompts (as in earlier versions of git).

The environment variable may only be used to enable, not to disable
git's password prompt.  This behavior mimics GIT_NO_VERIFY; the mere
existence of the variable is all that is checked.

30dd916348 http.c: prompt for SSL client certificate password
If an SSL client certificate is enabled (via http.sslcert or
GIT_SSL_CERT), prompt for the certificate password rather than
defaulting to OpenSSL's password prompt.  This causes the prompt to only
appear once each run.  Previously, OpenSSL prompted the user *many*
times, causing git to be unusable over HTTPS with client-side
certificates.

Note that the password is stored in memory in the clear while the
program is running.  This may be a security problem if git crashes and
core dumps.

The user is always prompted, even if the certificate is not encrypted.
This should be fine; unencrypted certificates are rare and a security
risk anyway.

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.
