Require a struct remote in transport_get()
cmd_ls_remote() was calling transport_get() with a NULL remote and a
non-NULL url in the case where it was run outside a git

remote_get(), which works fine outside a git repository, and can also
take global options into account.
This fixes a tiny and obscure bug where "git ls-remote" without a repo
didn't support global url.*.insteadOf, even though "git clone" and

Fix incorrect error check while reading deflated pack data
The loop in get_size_from_delta() feeds a deflated delta data from the
pack stream _until_ we get inflated result of 20 bytes[*] or we reach the
end of stream.
Side note. This magic number 20 does not have anything to do with the
size of the hash we use, but comes from 1a3b55c (reduce delta head
inflated size, 2006-10-18).
The loop reads like this:
do {
in = use_pack();
stream.next_in = in;
st = git_inflate(&stream, Z_FINISH);
curpos += stream.next_in - in;
} while ((st == Z_OK || st == Z_BUF_ERROR) &&
stream.total_out < sizeof(delta_head));
This git_inflate() can return:
- Z_STREAM_END, if use_pack() fed it enough input and the delta itself
was smaller than 20 bytes;
- Z_OK, when some progress has been made;
- Z_BUF_ERROR, if no progress is possible, because we either ran out of
input (due to corrupt pack), or we ran out of output before we saw the
end of the stream.
The fix b3118bd (sha1_file: Fix infinite loop when pack is corrupted,
2009-10-14) attempted was against a corruption that appears to be a valid
stream that produces a result larger than the output buffer, but we are
not even trying to read the stream to the end in this loop. If avail_out
becomes zero, total_out will be the same as sizeof(delta_head) so the loop
will terminate without the "fix". There is no fix from b3118bd needed for
this loop, in other words.
The loop in unpack_compressed_entry() is quite a different story. It
feeds a deflated stream (either delta or base) and allows the stream to
produce output up to what we expect but no more.
do {
in = use_pack();
stream.next_in = in;
st = git_inflate(&stream, Z_FINISH);
curpos += stream.next_in - in;
} while (st == Z_OK || st == Z_BUF_ERROR)
This _does_ risk falling into an endless interation, as we can exhaust
avail_out if the length we expect is smaller than what the stream wants to
produce (due to pack corruption). In such a case, avail_out will become
zero and inflate() will return Z_BUF_ERROR, while avail_in may (or may
not) be zero.
But this is not a right fix:
do {
in = use_pack();
stream.next_in = in;
st = git_inflate(&stream, Z_FINISH);
+ if (st == Z_BUF_ERROR && (stream.avail_in || !stream.avail_out)
+ break; /* wants more input??? */
curpos += stream.next_in - in;
} while (st == Z_OK || st == Z_BUF_ERROR)
as Z_BUF_ERROR from inflate() may be telling us that avail_in has also run
out before reading the end of stream marker. In such a case, both avail_in
and avail_out would be zero, and the loop should iterate to allow the end
of stream marker to be seen by inflate from the input stream.
The right fix for this loop is likely to be to increment the initial
avail_out by one (we allocate one extra byte to terminate it with NUL
anyway, so there is no risk to overrun the buffer), and break out if we
see that avail_out has become zero, in order to detect that the stream
wants to produce more than what we expect. After the loop, we have a
check that exactly tests this condition:
So here is a patch (without my previous botched attempts) to fix this
issue. The first hunk reverts the corresponding hunk from b3118bd, and
the second hunk is the same fix proposed earlier.

sha1_file: Fix infinite loop when pack is corrupted
Some types of corruption to a pack may confuse the deflate stream
which stores an object. In Andy's reported case a 36 byte region
of the pack was overwritten, leading to what appeared to be a valid
deflate stream that was trying to produce a result larger than our
allocated output buffer could accept.
Z_BUF_ERROR is returned from inflate() if either the input buffer
needs more input bytes, or the output buffer has run out of space.
Previously we only considered the former case, as it meant we needed
to move the stream's input buffer to the next window in the pack.
We now abort the loop if inflate() returns Z_BUF_ERROR without
consuming the entire input buffer it was given, or has filled
the entire output buffer but has not yet returned Z_STREAM_END.
Either state is a clear indicator that this loop is not working
as expected, and should not continue.
This problem cannot occur with loose objects as we open the entire
loose object as a single buffer and treat Z_BUF_ERROR as an error.

not encountered. The conservative choice has been made to set NO_MMAP in

The segfault happens in refs.c:read_ref_at(). The mmap succeeds, and the

Fix the exit code of MSVC build scripts on cygwin
During an MSVC build on cygwin, the make program did not notice
when the compiler or linker exited with an error. This was caused
by the scripts exiting with the value returned by system() directly.
On POSIX-like systems, such as cygwin, the return value of system()
has the exit code of the executed command encoded in the first byte
(ie the value is shifted up by 8 bits). This allows the bottom
7 bits to contain the signal number of a terminated process, while
the eighth bit indicates whether a core-dump was produced. (A value
of -1 indicates that the command failed to execute.)
The make program, however, expects the exit code to be encoded in the
bottom byte. Futhermore, it apparently masks off and ignores anything
in the upper bytes.
However, these scripts are (naturally) intended to be used on the
windows platform, where we can not assume POSIX-like semantics from
a perl implementation (eg ActiveState). So, in general, we can not
assume that shifting the return value right by eight will get us
the exit code.
In order to improve portability, we assume that a zero return from
system() indicates success, whereas anything else indicates failure.
Since we don't need to know the exact exit code from the compiler
or linker, we simply exit with 0 (success) or 1 (failure).

HEAD as a symbolic-ref; but cd67e4d (Teach 'git pull' about --rebase,
2007-11-28) moved the command away from where the check is, and nobody
noticed the breakage. Ever since, $? has always been 0 (tr at the end of
the pipe to find merge_head never fails) and other case arms were never
reached.
These days, error_on_no_merge_candidates function is prepared to handle a
detached HEAD case, which was what the code this patch removes used to
handle.

show-branch: fix segfault when showbranch.default exists
When running "git show-branch" without any parameter in a repository that
has showbranch.default defined, we used to rely on the fact that our
handcrafted option parsing loop never looked at av[0].
The array of default strings had the first real command line argument in
default_arg[0], but the option parser wanted to look at the array starting
at av[1], so we assigned the address of -1th element to av to force the
loop start working from default_arg[0].
This no longer worked since 5734365 (show-branch: migrate to parse-options
API, 2009-05-21), as parse_options_start() saved the incoming &av[0] in
its ctx->out and later in parse_options_end() it did memmove to ctx->out
(with ctx->cpidx == 0), overwriting the memory before default_arg[] array.
I am not sure if this is a bug in parse_options(), or a bug in the caller,
and tonight I do not have enough concentration to figure out which. In
any case, this patch works the issue around.

Fix some printf format warnings
commit 51ea551 ("make sure byte swapping is optimal for git"
2009-08-18) introduced a "sane definition for ntohl()/htonl()"
for use on some GNU C platforms. Unfortunately, for some of
these platforms, this results in the introduction of a problem
which is essentially the reverse of a problem that commit 6e1c234
("Fix some warnings (on cygwin) to allow -Werror" 2008-07-3) was
intended to fix.
In particular, on platforms where the uint32_t type is defined
to be unsigned long, the return type of the new ntohl()/htonl()
is causing gcc to issue printf format warnings, such as:
warning: long unsigned int format, unsigned int arg (arg 3)
(nine such warnings, covering six different files). The earlier
commit (6e1c234) needed to suppress these same warnings, except
that the types were in the opposite direction; namely the format
specifier ("%u") was 'unsigned int' and the argument type (ie the
return type of ntohl()) was 'long unsigned int' (aka uint32_t).
In order to suppress these warnings, the earlier commit used the
(C99) PRIu32 format specifier, since the definition of this macro
is suitable for use with the uint32_t type on that platform.
This worked because the return type of the (original) platform
ntohl()/htonl() functions was uint32_t.
In order to suppress these warnings, we change the return type of
the new byte swapping functions in the compat/bswap.h header file
from 'unsigned int' to uint32_t.

add NORETURN_PTR for function pointers
Some compilers (including at least MSVC and ARM RVDS) supports
NORETURN on function declarations, but not on function pointers.
This patch makes it possible to define NORETURN for these compilers,
by splitting the NORETURN macro into two - one for function
declarations and one for function pointers.

improve reflog date/number heuristic
When we show a reflog, we have two ways of naming the entry:
by sequence number (e.g., HEAD@{0}) or by date (e.g.,
HEAD@{10 minutes ago}). There is no explicit option to set
one or the other, but we guess based on whether or not the
user has provided us with a date format, showing them the
date version if they have done so, and the sequence number
otherwise.
This usually made sense if the use did something like "git
log -g --date=relative". However, it didn't make much sense
if the user set the date format using the log.date config
variable; in that case, all of their reflogs would end up as
dates.
This patch records the source of the date format and only
triggers the date-based view if --date= was given on the
command line.
