foo-* to foo-[0-9]*. This is to cause the dependencies to match only the
packages whose base package name is "foo", and not those named "foo-bar".
A concrete example is p5-Net-* matching p5-Net-DNS as well as p5-Net. Also
change dependency examples in Packages.txt to reflect this.
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
Add a new USE_LIBTOOL definition that uses the libtool package instead of
pkglibtool which is now considered outdated.
USE_PKGLIBTOOL is available for backwards compatibility with old packages
but is deprecated for new packages.
*) Do no longer use -woff in CFLAGS for IRIX 6.5.2 and above.
*) Replaced ``while (1)'' constructs with ``for (;;)'' because some
compilers like this more and do not warn about constant expressions.
*) Added hint to pth.pod that ``pth_join(<tid>, NULL)'' is allowed.
*) Cancel and join the ticker thread explicitly in test_select.c
*) Removed unnecessary code in pth_event.c
*) Add special namespace workarounds to pthread.h.in for HPUX
platforms where the pthread_kill() prototypes conflict without this.
*) Added HISTORY document where we now write down the evolution
and release dates of Pth to have a concise history reference.
[Ralf S. Engelschall]
*) Added USERS document where we now collect references to
software packages utilizing GNU Pth.
[Ralf S. Engelschall]
*) Fixed a subtle typo in pth.pod about thread-safe functions
and finished documentation of pth_attr_set/pth_attr_get functions.
[James Robinson <jlrobins@uncc.edu>, Jeremie <jeremie@jabber.org>]
to 1.2.3):
*) Better detection and support for Unix platform differences
*) More complete support for hard syscall wrapping
*) Memory debugging support via Dmalloc library and --with-dmalloc
*) Added a PTH_CTRL_DUMPSTATE to pth_ctrl()
*) Removed PTH_EVENT_PID and enhanced PTH_EVENT_FUNC
*) First cut for Win32/CygWin support
*) New `make striptease' feature for developers
*) New pth.m4 file for using Pth inside Autoconf based packages
*) New large pthread.pod manual page which contains full Pthread API
*) Fixed numerious memory leaks
*) Numerous bugfixes and cleanups
Changes are:
*) Changed internal handling of spawned threads: they are now really
inserted to the top of the priority queue to make sure a thread is
guarrantied to be dispatched next when one calls pth_yield(NULL)
directly after a pth_spawn(). This is especially interesting for
programming with the co-routine paradigm where it allows one to better
control the startup of a co-routine.
[Ralf S. Engelschall, Jens Andersen <Jens@trw.nl>]
*) Fixed pthread_cancel(): a switch statement was incorrect (three
breaks were missing to stop falling through).
[Jens Andersen <Jens@trw.nl>]
*) Change internal `_pthread' prefix to `__pthread'.
[Ralf S. Engelschall]
*) Enhanced backward compatibility stuff for Pthread draft 4 (DCE Threads)
in pthread.h.in: When _POSIX_BACKCOMPAT is defined before the pthread.h
header is included one now gets a lot more backward compatibility
mappings.
[Ralf S. Engelschall]
*) Optimize internal processing by inlining various small functions from
pth_ring.c, pth_pqueue.c and pth_sched.c which are called a lot.
[Ralf S. Engelschall]
*) Optimized readline() in test_common.c
[Ralf S. Engelschall]
*) Added specific support for Linux/glibc/mc68000 to pth_mctx.c
[Roman Hodek <Roman.Hodek@informatik.uni-erlangen.de>]
*) Updated INSTALL document for --enable-optimize.
[Ralf S. Engelschall]
Changes include:
*) Enhanced test program of AC_CHECK_STACKGROWTH in aclocal.m4 to
make sure the test variables are not optimized away by the
compiler and this way lead to incorrect check results.
[Martin Kraemer <martin.kraemer@mch.sni.de>, Ralf S. Engelschall]
*) Fixed default stack size: was 32*16384 (=512KB) instead
of the intended 32*1024 (=32KB).
[Ralf S. Engelschall]
*) Added --enable-optimize flag to configure with selected
standard optimization flags of GCC.
[Ralf S. Engelschall]
*) Added SUPPORT file to source tree.
[Ralf S. Engelschall]
*) Added test_philo, Dijkstra's Five Dining Philosophers ;)
[Ralf S. Engelschall]
*) Add "auto" qualifier to PTH_STACKGROWTH test program
to make sure the variables are placed into the stack.
[Ralf S. Engelschall]
*) Use predetermined $PLATFORM of configure also in Makefile
[Ralf S. Engelschall]
Changes include:
*) Changed return type of pth_yield() from `void' to `int' to
be able to return an error FALSE/EINVAL in case the `tid'
argument specified an invalid or still not ready thread.
[Kurt D. Zeilenga <Kurt@OpenLDAP.Org>, Ralf S. Engelschall]
*) Fixed description of pth_yield() in pth.pod.
[Kurt D. Zeilenga <Kurt@OpenLDAP.Org>, Ralf S. Engelschall]
Changes between 1.0.x and 1.1.x (03-Aug-1999 to 19-Aug-1999):
*) Fixed and enhanced POSIX semantics for replacement functions
*) Cleaned up source tree
*) Overhauled Autoconf environment
*) Enhanced setjmp/longjmp support
*) Support for SVR4/SUSv2 makecontext(2) mctx variant
*) Barrier synchronization objects
*) Sfio support via special Pth/Sfio discipline
*) Overhauled filedescriptor handling
Notable changes are:
*) Backport from Pth 1.1b2:
Fixed ring walking inside both public pth_msgport_find() function
and the internal pth_mutex_releaseall() function.
*) Backport from Pth 1.1b1:
In pth_mctx.c the signal stack was not restored correctly.
*) Backport from Pth 1.1b1:
Fixed test_select.c: a char has to be used for read(2) and not an int.
And replaced a bogus stdio fgetc() in test_select with pth_read().
*) Backport from Pth 1.1b1:
Fixed AC_CHECK_NSIG test and this way PTH_NSIG define.
*) Backport from Pth 1.1b1:
Fixed timeout handling in pth_select().
