o In the rwlock code: move a duplicated check inside an if..else to after
the if...else clause.
o When initializing a static rwlock move the initialization check
inside the lock.
o In thr_setschedparam.c: When breaking out of the trylock...retry if busy
loop make sure to reset the mtx pointer to null if the mutex is nolonger
in a queue.
code on the existence of the relevant libraries (actually,
the existence of the include files).
This will allow the library to be easily ported to systems
that don't have these libraries. (Of course, it also means
that clients using the library on such systems will not be
able to take advantage of the automatic compression format
detection.)
to describe the 4.4BSD extension of accepting arguments outside the range
of unsigned char. This gives us freedom to remove this extension when we
remove the <rune.h> interface in FreeBSD 6.
These convert plain ASCII characters in-line, making them only slightly
slower than the single-byte ("NONE" encoding) version when processing
ASCII strings.
in the regular ustar header that are overridden by the pax
extended attributes. As a result, it makes perfect sense to
use numeric extensions in the regular ustar header so that readers
that don't understand pax extensions but do understand some other
extensions can still get useful information out of it.
This is especially important for filesizes, as the failure to
read a file size correctly can get the reader out of sync.
This commit introduces a "non-strict" option into the internal
function to format a ustar header. In non-strict mode, the formatter
will use longer octal values (overwriting terminators) or binary
("base-256") values as needed to ensure that large file sizes,
negative mtimes, etc, have the correct values stored in the regular
ustar header.
archive_version: Returns a text string, e.g., "libarchive 1.00.000"
archive_api_version: Returns the SHLIB major version
archive_api_feature: Returns a feature number useful for answering
questions such as "Is this recent enough to do XXX?"
The last two also have macros defined in archive.h, so you can compare
the compile-time and run-time environments. (In particular, you can
compare ARCHIVE_API_VERSION to archive_api_version() to detect library
version mismatches.)
With these in hand, it will soon be time to turn on the
shared-library version of libarchive... stay tuned.
Thanks to: David O'Brien for pointing this out.
Also, add in a few additional portability tweaks and make a few
more things conditional on features (HAVE_XXXX macros) rather
than platform.
In particular, this means we can now correctly read gtar archives that
contain timestamps prior to the start of the Epoch.
Also, make the code in this area more portable. ANSI C99 headers are
not yet ubiquitous (for example, FreeBSD 4 still lacks them), so be
prepared for systems that don't have the INT64_MAX, INT64_MIN, and
UINT64_MAX macros. This version still requires int64_t and uint64_t be
defined (which can be done in archive_platform.h if necessary), but
doesn't require them to be exactly 64 bits.
convenient when the source string isn't null-terminated.
Implement the other conversion functions (mbstowcs(), mbsrtowcs(), wcstombs(),
wcsrtombs()) in terms of these new functions.
for statfs(2). This is false, if the pathname specified
is a regular file, then the information for the file
system that the file lives on will be returned.

gcc is using. This fixes devstat consumers (like vmstat, iostat,
systat) so they don't print crazy zillion digit numbers for
disk transfers and bandwidth.
According to gcc, long doubles are 64-bits, rather than 128 bits
like the SVR4 ABI spec wants them to be.. Note that MacOSX also treats
long doubles as 64-bits, and not 128 bits, so we are in good company.
