Allowing any refname component to end with ".lock" is looking for
trouble; for example,
$ git br foo.lock/bar
$ git br foo
fatal: Unable to create '[...]/.git/refs/heads/foo.lock': File exists.
Therefore, do not allow any refname component to end with ".lock".

Change check_ref_format() to take a flags argument that indicates what
is acceptable in the reference name (analogous to "git
check-ref-format"'s "--allow-onelevel" and "--refspec-pattern"). This
is more convenient for callers and also fixes a failure in the test
suite (and likely elsewhere in the code) by enabling "onelevel" and
"refspec-pattern" to be allowed independently of each other.
Also rename check_ref_format() to check_refname_format() to make it
obvious that it deals with refnames rather than references themselves.

Previously most bad characters were indicated by returning 1, but "*"
was special-cased to return 2 instead of 1. One caller examined the
return value to see whether the special case occurred.
But it is easier (to document and understand) for bad_ref_char()
simply to return a boolean value, treating "*" like any other bad
character. Special-case the handling of "*" (which only occurs in
very specific circumstances) at the caller. The resulting calling
code thereby also becomes more transparent.

Also add tests of the new options. (Actually, one big reason to add
the new options is to make it easy to test check_ref_format(), though
the options should also be useful to other scripts.)
Interpret the result of check_ref_format() based on which types of
refnames are allowed. However, because check_ref_format() can only
return a single value, one test case is still broken. Specifically,
the case "git check-ref-format --onelevel '*'" incorrectly succeeds
because check_ref_format() returns CHECK_REF_FORMAT_ONELEVEL for this
refname even though the refname is also CHECK_REF_FORMAT_WILDCARD.
The type of check that leads to this failure is used elsewhere in
"real" code and could lead to bugs; it will be fixed over the next few
commits.

Previously, get_sha1_hex() would read one character past the end of a
null-terminated string whose strlen was an even number less than 40.
Although the function correctly returned -1 in these cases, the extra
memory access might have been to uninitialized (or even, conceivably,
unallocated) memory.
Add a check to avoid reading past the end of a string.

Adding a new command line option to receive-pack and feed it from
send-pack is not an acceptable way to add features, as there is no
guarantee that your updated send-pack will be talking to updated
receive-pack. New features need to be added via the capability mechanism
negotiated over the protocol.

"svn dcommit --mergeinfo" replaces the svn:mergeinfo property in an
upstream SVN repository with the given text. The svn:mergeinfo
property may contain commits originating on multiple branches,
separated by newlines.
Cause space characters in the mergeinfo to be replaced by newlines,
allowing a user to create history representing multiple branches being
merged into one.
Update the corresponding documentation and add a test for the new
functionality.

In the case where sb is initialized to the slopbuf (through
strbuf_init(sb,0) or STRBUF_INIT), strbuf_grow() loses the terminating
nul: it grows the buffer, but gives ALLOC_GROW a NULL source to avoid
it being freed. So ALLOC_GROW does not copy anything to the new
memory area.
This subtly broke the call to strbuf_getline in read_next_command()
[fast-import.c:1855], which goes
strbuf_detach(&command_buf, NULL); # command_buf is now = STRBUF_INIT
stdin_eof = strbuf_getline(&command_buf, stdin, '\n');
if (stdin_eof)
return EOF;
In strbuf_getwholeline, this did
strbuf_grow(sb, 0); # loses nul-termination
if (feof(fp))
return EOF;
strbuf_reset(sb); # this would have nul-terminated!
Valgrind found this because fast-import subsequently uses prefixcmp()
on command_buf.buf, which after the EOF exit contains only
uninitialized memory.
Arguably strbuf_getwholeline is also broken, in that it touches the
buffer before deciding whether to do any work. However, it seems more
futureproof to not let the strbuf API lose the nul-termination by its
own fault.
So make sure that strbuf_grow() puts in a nul even if it has nowhere
to copy it from. This makes strbuf_grow(sb, 0) a semantic no-op as
far as readers of the buffer are concerned.
Also remove the nul-termination added by strbuf_init, which is made
redudant.

Since c426003 (format-patch: add --no-cc, --no-to, and
--no-add-headers, 2010-03-07) the tests have checked for an option
called --no-add-headers introduced by letting the user negate
--add-header.
However, the parseopt machinery does not automatically pluralize
anything, so it is in fact called --no-add-header.
Since the option never worked, is not documented anywhere, and
implementing an actual --no-add-headers would lead to silly code
complications, we just adapt the test to the code.

Most kinds of failure in 'git format-patch --stdout >output' will
result in an empty 'output'. This slips past checks that only verify
absence of output, such as the '! grep ...' that are quite prevalent
in t4014.
Introduce a helper check_patch() that checks that at least From, Date
and Subject are present, thus making sure it looks vaguely like a
patch (or cover letter) email. Then insert calls to it in all tests
that do have positive checks for content.
This makes two of the tests fail. Mark them as such; they'll be
fixed in a moment.
