Changes between 1.4a3 and 1.4.0 (29-Jul-2000 to 24-Mar-2001)
*) Added PTHREAD_PRIO_XXXX definitions to pthread.h for
conformance to the POSIX/SUSv2 Pthread API.
*) Implemented the pthread_{set,get}concurrency() API parts of
POSIX/SUSv2, although internally we are (allowed to be) free to not
do anything based on the requested level.
*) Adjusted all pthread_attr_getXXXX() functions to use a "const
pthread_attr_t *" as the first argument instead of "pthread_attr_t
*" to fully-conform to POSIX/SUSv2.
*) Added ENOSYS-stubs for pthread_attr_{set,get}guardsize()
to the Pthread API to be more complete with POSIX/SUSv2 specs.
*) Added still missing soft system call mapping to Pth and Pthread
APIs for functions recv(2), send(2), recvfrom(2) and sendto(2).
*) Upgraded to GNU shtool 1.5.2
*) Fixed an even-manager bug which causes a thread that calls
pth_nap() to never woke up if the only elapsed event was a timer.
*) Added `#define _BITS_SIGTHREAD_H' to pthread.h to avoid inclusion
of bits/sigthread.h (from signal.h) on Linux running glibc6 2.2.
*) Added support to Makefile.in for DESTDIR variable. This allows
easier rolling of installation tarballs (for instance from within
RPM or similar facilities) by using "make install DESTDIR=/tmp/pth".
*) Implemented a pth_system(3) function which is a thread-aware
clone of the POSIX system(2) function.
*) Fixed typos in pth.pod: "fd" -> "s" for pth_connect/pth_accept.
*) Make --disable-shared the default under Solaris-2.[78]/x86, because
it is known to segfault sporadically if Pth is built as a DSO. As
traces showed, it is not a Pth problem, but it looks like a problem
with the dynamic linker on Solaris/x86. The same Solaris versions
on SPARC don't have this problem.
*) Updated copyright messages to cover new year 2001.
*) Fixed quoting in configure.in
*) Let pth_sleep(3) and pth_usleep(3) immediately return
if an argument of zero is given.
*) Fixed pthread.pod: the newer pod2man versions seems to dislike
embedded comments, so I moved them to the top of the file.
*) Changed CVS URL in HACKING document.
*) Mention http://www.mail-archive.com/pth-users@gnu.org/ in pth.pod
and SUPPORT document.
Changes between 1.4a2 and 1.4a3 (01-Jul-2000 to 29-Jul-2000)
*) Upgraded to GNU shtool 1.5.1
*) Fixed (unused) pth_time_mul() function: operator & replaced by %
*) Use --disable-lock for ltconfig.
*) Fixed a few typos in pth.pod.
Changes between 1.4a1 and 1.4a2 (16-Apr-2000 to 01-Jul-2000)
*) Upgraded to GNU Shtool 1.5.0
*) Added OS/390 support to config.sub.
*) Upgraded rse-pmt.ps paper to latest version as it was
published on USENIX 2000.
*) Stack boundary fixes for Interactive Unix support
(--with-mctx-dsp=sjljisc). This allows one also to use this
variant for Interix on Window-NT (a POSIX.1 compliant subsystem).
*) Upgraded to GNU Libtool 1.3.5
*) Fixed config.param parsing: IF is now also allowed on
VARIABLE=VALUE lines.
*) Allow for convinience reasons pth_usleep() to accept also
arguments greater than 1000000.
*) Updated HACKING document.
*) Fixed warnings in pth_string.c related to va_arg() usage
and implicit type conversions.
*) Merge from Pth 1.3.5:
Fixed the <sys/select.h> checks in Autoconf: the logic
was reversed and this way <sys/select.h> wasn't included on
platforms were it existed and included where it wasn't present.
Changes between 1.3.3 and 1.4a1 (10-Mar-2000 to 16-Apr-2000)
*) Added a new feature to config.param: parameters can be extended
with ``<space>IF<space><shell-test>''. Then the preceeding
parameter is only added to the command line if the <shell-test>
returns 0. <shell-test> can be anything which is possible in a
Bourne-Shell `if' construct's expression.
*) Fixed usage of `volatile' qualifier in pointer context.
*) Now check also for -Wno-long-long compiler option under
--enable-debug, because pth_string.c contains `long long' stuff.
*) Now pth.h and pthread.h include the non-standard <sys/select.h>
header on brain-dead platforms (like AIX) to get the definition of
fd_set (which is required for the pth_select prototype).
*) Fixed auto-configuration for ISC and Win32/Cygwin platforms.
*) Removed -L. from $(LDFLAGS) in Makefile.in, because this
is not required (libtool already takes care of this).
*) Added a RPM spec file pth.spec which allows one to build RPM
packages directly from the Pth distribution tarball through a
simple `rpm -tb pth-1.X.Y.tar.gz' call.
*) Removed the too explicit `-m 644' from the libtool/shtool
installation command for libpth.la and instead use a `umask 022'.
The reason is because some platforms require the shared libraries
to be executable, so we cannot use an explicit mode. But we use the
umask to make sure we don't result in world or group writeable files.
*) Use full-path /sbin/sysctl in config.guess on FreeBSD because
not all users have /sbin in their $PATH.
*) Added eight new I/O functions pth_{recv,recvfrom,send,sendto}[_ev](3)
which correspond to the counterparts in UNIX98 (SUSv2).
*) Replaced for security reasons sprintf() and vsprintf() calls
with own pth_snprintf() and pth_vsnprintf() functions from the new
pth_string.c source.
*) Speeded up pth_ring_t handling by inlining code and by maintaining
number of contained nodes explicitly to avoid an O(n) operation when
the number of elements are requested.
*) Upgraded to GNU shtool 1.4.9
