2016-02-29 Keith Marshall <keithmarshall at users dot sourceforge dot net>
* ptw32_timespec.c: Fix C90 warnings from GCC; int64_t -> uint64_t
2016-02-18 Carey Gister <careygister at outlook dot com>
* dll.c (DllMain): Should not be defined for static library builds.
Doing so prevents static linking with a dll library.
2015-11-01 Anurag Sharma <anurags at fb dot com>
* ptw32_MCS_lock.c: Fix a race condition causing crashes.
This race condition was also analysed and reported with a slightly
different fix independently by Jonathan Brown at VMware.
2015-11-01 Mark Smith <masmith at fb dot com>
* ptw32_relnillisecs.c: Fix erroneous 0-time waits, symptomizing as
busy-spinning eating CPU. When the time to wait is specified to be less
than 1 millisecond were erroneously rounded down to 0; Modify WinCE
dependency.
* ptw32_timespec.c: Remove NEED_FTIME conditionality.
2015-06-31 Dimitry <>
* sem_init.c: Remove double free() when NEED_SEM defined (for
early versions of WinCE).

2014-05-28 Jaeeun Choi <jaeeun at mdstec dot com>
* pthread_mutex_init.c: Check and free malloced robustNode element if
init is returning an ENOSPC error.
2013-12-10 Ross Johnson <ross dot johnson at homemail dot com dot au>
* Makefile (*-small-static): Removed all small-static targets in the MS
toolchain builds due to failures of TLS in apps linked with these
library builds, specifically fails tests/semaphore3.c. The other static
builds pass this test.
* dll.c: Remove unused MinGW static linking hooks; See autostatic.c.
Hope to incorporate a working set of hooks here for gcc that supports
PIMAGE_TLS_CALLBACK later at which point autostatic.c will be required
only for older compilers.
2013-12-09 Ross Johnson <ross dot johnson at homemail dot com dot au>
* Makefile (.rc.res): Add logic to extract target CPU from different
environments.
2013-07-23 Keith Clanton <keith dot clanton at cloudcar dot com>

2013-06-06 Ross Johnson <ross dot johnson at homemail dot com dot au>
* pthread.h (_POSIX_THREAD_ATTR_STACKADDR): Now set to -1. The API
prototypes are defined but return ENOSYS; previously the addr value was
stored in the attribute struct and retreivable but unused.
* pthread_attr_setstackaddr.c: Should return ENOSYS rather than silently
ignore the setting.
* pthread_attr_getstackaddr.c: Likewise.
* pthread_attr_getaffinity_np.c: Initial version.

Fix function calls involving TCHAR.
2012-10-29 Ross Johnson <ross dot johnson at homemail dot com dot au>

search to system path.
2012-10-24 Stephane Clairet <Stephane dot Clairet at 4d dot com>
* pthread_key_delete.c: Bug fix - move keylock release to after the
while loop. (This bug first was introduced at release 2.9.1)
2012-10-16 Ross Johnson <ross dot johnson at homemail dot com dot au>
* Makefile: Remove SDK environment setting; now needs to be done
explicitly before running any nmake.
* GNUmakefile: Move per command-line ARCH setting to TESTS_ENV.
2012-10-04 Ross Johnson <ross dot johnson at homemail dot com dot au>

* implement.h (_sched_cpu_set_vector_): Created as the private equivalent
of cpu_set.
(pthread_thread_t_.cpuset): Type change.
* sched_setaffinity.c: Reflect changes to cpu_set_t and _sched_cpu_set_vector_.
* pthread_setaffinity.c: Likewise.
* create.c: Likewise.
* pthread_self.c: Likewise.
* ptw32_new.c: Likewise.
2012-09-28 Ross Johnson <ross dot johnson at homemail dot com dot au>
* pthread.c: pulls all individual source modules into a single
translation unit.
* common.mk: Remove everything related to the non-inlined dll targets.
This removes all the intermediate .c files that #include other .c files
except for pthread.c.
* Makefile: Remove and rename targets; remove or edit variables. All
of this is to remove the intermediate translation unit aggregation
source files.
* GNUmakefile: Likewise.
* attr.c: Removed.
* barrier.c: Removed.
* cancel.c: Removed.
* condvar.c: Removed.

2012-09-28 Ross Johnson <ross dot johnson at homemail dot com dot au>
* Makefile: expand on rudimentary install target; add DEST_LIB_NAME
variable defaulting to "pthread.lib".
* GNUmakefile: Add install target similar to Makefile with DEST_LIB_NAME
defaulting to "libpthread.a".
2012-09-28 Daniel Richard. G <danielg at teragram dot com>
* all: #include<config.h>; renamed HAVE_PTW32_CONFIG_H define in
build files to HAVE_CONFIG_H since we no longer need a
uniquely-named symbol for this.
* Bmakefile: Removed _WIN32_WINNT assignment from build files since
this is now handled in source.
* Wmakefile: Likewise.
* Makefile: Added mkdir invocations to "install" target.
* common.mk: Elaborated the pthread.$(OBJEXT) dependency list.
* pthread.h: Removed the #include"config.h" bit.
2012-09-23 Ross Johnson <ross dot johnson at homemail dot com dot au>
* GNUmakefile: Modify "all-tests" to use new targets in tests
GNUmakefile.
* Makefile: Similarly.
2012-09-22 Daniel Richard. G <danielg at teragram dot com>
* GNUmakefile: Reordered the command lines in the "help" target
to match the ordering of the targets in the makefile, which IMO
is nicer to the eye; tweaked some of the parentheticals for better
clarity; delete *.manifest files, in case the user just finished
doing an MSVC build.
* Makefile: Use *.static_stamp for the static targets instead of
*.static; added a note re VC++6 and /EHs vs. /EHa; reordered the
targets, and added a number of new ones (e.g. VSE-small-static);
added a note recommending *-inlined and *-small-static to make
things a little easier for users bewildered by the large number of
targets; reworked the all-tests[-cflags] targets so that (1) more
useful targets are built first (the small-static targets make it
easier to track down compilation errors), (2) *-debug build and
test targets can be used, (3) less-useful build/test permutations
are enabled only if EXHAUSTIVE and/or MORE_EXHAUSTIVE is defined,
and (4) /MDd and /MTd are covered too; "nmake all-tests-cflags
EXHAUSTIVE=1 MORE_EXHAUSTIVE=1" takes a few hours to run; moved
some of the VCE targets up, since the pattern in the file was
already to list VCE targets first, then VSE, then VC; actually
touch the stamp file in the stamp targets.
* README.NONPORTABLE: It's "DllMain", not "dllMain".
* common.mk: Start of an attempt to define dependencies for
pthread.$(OBJEXT).
* implement.h: Generalized __PTW32_BROKEN_ERRNO into
PTW32_USES_SEPARATE_CRT; don't do the autostatic-anchoring thing
if we're not building the library!
* pthread.h: Moved the __PTW32_CDECL bit into sched.h. pthread.h
already #includes sched.h, so the latter is a good place to put
definitions that need to be shared in common; severely simplified
the errno declaration for Open Watcom, made it applicable only to
Open Watcom, and made the comment less ambiguous; updated the long
comment describing __PTW32_BROK^WPTW32_USES_SEPARATE_CRT; added
(conditional) declaration of pthread_win32_set_terminate_np(), as
well as __ptw32_terminate_handler (so that eh.h doesn't have to get
involved).
* pthread_cond_wait.c: Missed a couple of errno conversions.
* pthread_mutex_consistent.c: Visual Studio (either 2010 or 2008
Express, don't recall now) actually errored out due to charset
issues in this file, so I've replaced non-ASCII characters with
ASCII approximations.
* ptw32_threadStart.c: Big rewrite of __ptw32_threadStart().
Everything passes with this, except for GCE (and I can't figure
out why).
* sched.h: Moved the __PTW32_CDECL section here (and made it
idempotent); need to #include <stdlib.h> for size_t (one of the test
programs #includes sched.h as the very first thing); moved the
DWORD_PTR definition up, since it groups better with the pid_t
definition; also need ULONG_PTR, don't need PDWORD_PTR; can't use
PTW32_CONFIG_MSVC6, because if you only #include sched.h you
don't get that bit in pthread.h; use a cpp symbol
(__PTW32_HAVE_DWORD_PTR) to inhibit defining *_PTR if needed. Note
that this isn't #defined inside the conditional, because there are
no other instances of these typedefs that need to be disabled, and
sched.h itself is already protected against multiple inclusion;
DWORD_PTR can't be size_t, because (on MSVC6) the former is "unsigned
long" and the latter is "unsigned int" and C++ doesn't see them as
interchangeable; minor edit to the comment... I don't like saying
"VC++" without the "Microsoft" qualifier; use __PTW32_CDECL instead of
a literal __cdecl (this was why I moved the __PTW32_CDECL bit into this
file).
* semaphore.h: Put in another idempotentized __PTW32_CDECL bit here;
use __PTW32_CDECL instead of __cdecl, and fixed indentation of function
formal parameters.
2012-09-21 Ross Johnson <ross dot johnson at homemail dot com dot au>
* create.c: Major changes to incorporate CPU affinity inheritance.
* pthread_self.c: Likewise.

in tests/once3.c which was causing it to hang.
2012-09-03 Ross Johnson <ross dot johnson at homemail dot com dot au>
* Makefile: Remove descriptive info from help target, just list the
available targets. Output tends to be poorly formatted and cluttered
otherwise.

return statement.
2012-08-31 Daniel Richard. G <danielg at teragram dot com>
* implement.h (INLINE): only define if building the inlined make targets. G++
complained about undefined reference to __ptw32_robust_mutex_remove() because it
appears in separate compilation units for "make GCE".
2012-08-29 Ross Johnson <ross dot johnson at homemail dot com dot au>

useful help when "make" is run without a target argument.
2012-08-11 Daniel Richard. G <danielg at teragram dot com>

2011-07-06 Ross Johnson <ross dot johnson at homemail dot com dot au>
* pthread_cond_wait.c (pragma inline_depth): this is almost redundant
now nevertheless fixed thei controlling MSC_VER from "< 800" to
"< 1400" (i.e. any prior to VC++ 8.0).
* pthread_once.ci (pragma inline_depth): Likewise.

2011-07-05 Ross Johnson <ross dot johnson at homemail dot com dot au>
* pthread_win32_attach_detach_np.c: Use strncat_s if available
to removei a compile warning; MingW supports this routine but we
continue to use strncat anyway there because it is secure if
given the correct parameters; fix strncat param 3 to avoid
buffer overrun exploitation potential.
2011-07-03 Ross Johnson <ross dot johnson at homemail dot com dot au>
* pthread_spin_unlock.c (EPERM): Return success if unlocking a lock
that is not locked, because single CPU machines wrap a
PTHREAD_MUTEX_NORMAL mutex, which returns success in this case.

absolute path only which must be the Windows System folder.
2011-07-03 Daniel Richard G. <skunk at iskunk dot org>

* implement.h: Interlocked call and argument casting macro fixes
to support older and newer build environments.
2011-07-01 Ross Johnson <ross dot johnson at homemail dot com dot au>
* *.[ch] (__PTW32_INTERLOCKED_*): Redo 23 and 64 bit versions of these
macros and re-apply in code to undo the incorrect changes from
2011-06-29; remove some size_t casts which should not be required
and may be problematic.a
There are now two sets of macros:
PTW32_INTERLOCKED_*_LONG which work only on 32 bit integer variables;
PTW32_INTERLOCKED_*_SIZE which work on size_t integer variables, i.e.
LONG for 32 bit systems and LONGLONG for 64 bit systems.
* implement.h (MCS locks): nextFlag and waitFlag are now HANDLE type.
* ptw32_MCS_locks.c: Likewise.
* pthread.h (#include <setjmp.h>): Removed.

2011-06-30 Ross Johnson <ross dot johnson at homemail dot com dot au>
* pthread_once.c: Tighten 'if' statement casting; fix interlocked
pointer cast for 64 bit compatibility (missed yesterday); remove
the superfluous static cleanup routine and call the release routine
directly if popped.
* create.c (stackSize): Now type size_t.
* pthread.h (struct __ptw32_thread_t_): Rearrange to fix element alignments.
2011-06-29 Daniel Richard G. <skunk at iskunk dot org>
* ptw32_relmillisecs.c (ftime):
_ftime64_s() is only available in MSVC 2005 or later;
_ftime64() is available in MinGW or MSVC 2002 or later;
_ftime() is always available.
* pthread.h (long long): Not defined in older MSVC 6.
* implement.h (long long): Likewise.
* pthread_getunique_np.c (long long): Likewise.
2011-06-29 Ross Johnson <ross dot johnson at homemail dot com dot au>
* *.[ch] (__PTW32_INTERLOCKED_*): These macros should now work for
both 32 and 64 bit builds. The MingW versions are all inlined asm
while the MSVC versions expand to their Interlocked* or Interlocked*64
counterparts appropriately. The argument type have also been changed
to cast to the appropriate value or pointer size for the architecture.
2011-05-29 Ross Johnson <ross dot johnson at homemail dot com dot au>
* *.[ch] (#ifdef): Extended cleanup to whole project.
2011-05-29 Daniel Richard G. <skunk at iskunk dot org>
* Makefile (CC): Define CC to allow use of other compatible
compilers such as the Intel compilter icl.

* GNUmakefile (GCE-inlined-debug, DOPT): Fixed.
2011-04-31 Ross Johnson <ross.johnson at homemail.com.au>
* (robust mutexes): Added this API. The API is not
mandatory for implementations that don't support PROCESS_SHARED
mutexes, nevertheless it was considered useful both functionally
and for source-level compatibility.
2011-03-26 Ross Johnson <ross.johnson at homemail.com.au>
* pthread_getunique_np.c: New non-POSIX interface for compatibility
with some other implementations; returns a 64 bit sequence number
that is unique to each thread in the process.
* pthread.h (pthread_getunique_np): Added.
* global.c: Add global sequence counter for above.
* implement.h: Likewise.
2011-03-25 Ross Johnson <ross.johnson at homemail.com.au>

clean build via x86_64-w64-mingw32 cross toolchain on Linux i686
targeting x86_64 win64.
* ptw32_threadStart.c (__ptw32_threadStart): Routine no longer attempts
to pass [unexpected C++] exceptions out of scope but ends the thread
normally setting EINTR as the exit status.
* ptw32_throw.c: Fix C++ exception throwing warnings; ignore
informational warning.
* implement.h: Likewise with the corresponding header definition.
2011-03-04 Ross Johnson <ross.johnson at homemail.com.au>
* implement.h (__PTW32_INTERLOCKED_*): Mingw32 does not provide
the __sync_* intrinsics so implemented them here as macro
assembler routines. MSVS Interlocked* are emmitted as intrinsics
wherever possible, so we want mingw to match it; Extended to
include all interlocked routines used by the library; implemented
x86_64 versions also.
* ptw32_InterlockedCompareExchange.c: No code remaining here.
* ptw32_MCS_lock.c: Converted interlocked calls to use new macros.
* pthread_barrier_wait.c: Likewise.
* pthread_once.c: Likewise.
* ptw32_MCS_lock.c (__ptw32_mcs_node_substitute): Name changed to
__ptw32_mcs_node_transfer.
2011-02-28 Ross Johnson <ross.johnson at homemail.com.au>
* ptw32_relmillisecs.c: If possible, use _ftime64_s or _ftime64
before resorting to _ftime.
2011-02-27 Ross Johnson <ross.johnson at homemail.com.au>
* sched_setscheduler.c: Ensure the handle is closed after use.
* sched_getscheduler.c: Likewise.
* pthread.h: Remove POSIX compatibility macros; don't define
timespec if already defined.
* context.h: Changes for 64 bit.
* pthread_cancel.c: Likewise.
* pthread_exit.c: Likewise.
* pthread_spin_destroy.c: Likewise.
* pthread_timechange_handler_np.c: Likewise.
* ptw32_MCS_lock.c: Likewise; some of these changes may
not be compatible with pre Windows 2000 systems; reverse the order of
the includes.
* ptw32_threadStart.c: Likewise.
* ptw32_throw.c: Likewise.
2011-02-13 Ross Johnson <ross.johnson at homemail.com.au>
* pthread_self: Add comment re returning 'nil' value to
indicate failure only to win32 threads that call us.
* pthread_attr_setstackaddr: Fix comments; note this
function and it's compliment are now removed from SUSv4.

README.NONPORTABLE: Record a description of an obvious
method for nulling/comparing/hashing pthread_t using a
union; plus and investigation of a change of type for
pthread_t (to a union) to neutralise any padding bits and
bytes if they occur in pthread_t (the current pthread_t struct
does not contain padding AFAIK, but porting the library to a
future architecture may introduce them). Padding affects
byte-by-byte copies and compare operations.
2010-11-16 Ross Johnson <ross.johnson at homemail.com.au>

* ptw32_MCS_lock.c (__ptw32_mcs_node_substitute): New routine
to allow relocating the lock owners thread-local node to somewhere
else, e.g. to global space so that another thread can release the
lock. Used in pthread_barrier_wait.
(__ptw32_mcs_lock_try_acquire): New routine.
* pthread_barrier_init: Only one semaphore is used now.
* pthread_barrier_wait: Added an MCS guard lock with the last thread
to leave the barrier releasing the lock. This removes a deadlock bug
observed when there are greater than barrier-count threads
attempting to cross.
