Release 0.9:
|
|
- more ports (SH, IA-64, s390)
|
|
- many bug fixes
|
|
- timed sync object wait functions
|
|
- barrier implementation
|
|
- spinlocks implementation
|
|
- thread register on x86
|
|
- variable stack size and position on some platforms
|
|
|
|
Release 0.8:
|
|
(ehmm, forgot to update, don't know anymore)
|
|
|
|
Release 0.7:
|
|
- Destructors for thread-specific data now conform to the POSIX semantics
|
|
(call destructors again if non-NULL TSD remains after a round of
|
|
destruction).
|
|
- Implemented thread-specific data as a sparse array, allows more TSD keys
|
|
and smaller thread descriptors (Ulrich Drepper).
|
|
- Added "error checking" mutexes.
|
|
- Protect against multiple sigwait() on the same signals.
|
|
- Simplified implementation of semaphores when compare_and_swap is
|
|
not available.
|
|
- Fixed bug in fork() where stdin was closed if fork() was called before
|
|
the first pthread_create().
|
|
- Fixed bug in the gethostby*_r functions (bad result if null bytes
|
|
in addresses).
|
|
- Typos in manual pages corrected.
|
|
- First cut at a PowerPC port (not working yet, runs into problems
|
|
with gcc and with the C library).
|
|
|
|
Release 0.6:
|
|
- Validation of thread identifiers: no more crashes when operating on
|
|
a thread that has exited (based on Pavel Krauz's ideas).
|
|
- Added fallback implementation of semaphores for the 386 and the
|
|
Sparc.
|
|
- Fixed a bug in signal handling causing false restarts of suspended
|
|
threads.
|
|
- Fixed a bug in realtime scheduling causing all threads to have
|
|
default scheduling on Ix86 with libc5.
|
|
- With realtime scheduling, unlocking a mutex now restarts the
|
|
highest priority thread waiting on the mutex, not the
|
|
first-suspended thread (Richard Neitzel).
|
|
- Timing a process now returns cumulative times for all threads, not
|
|
just times for the initial thread (suggested by Wolfram Gloger).
|
|
- Cleaned up name space (internal defs prefixed by __, weak aliases
|
|
for non-portable extensions).
|
|
- MIPS port (contributed by Ralf Baechle).
|
|
|
|
Release 0.5:
|
|
- Signal-safe semaphores a la POSIX 1003.1b added.
|
|
- Locking bug in pthread_mutex_trylock over recursive mutexes fixed.
|
|
- Race conditions in thread cancellation fixed.
|
|
- Sparc port (contributed by Miguel de Icaza).
|
|
- Support for getpwnam_r and getpwuid_r.
|
|
- Added pthread_kill_other_threads_np to be used in conjunction with
|
|
exec*().
|
|
|
|
Release 0.4:
|
|
- Manual pages for all functions.
|
|
- Synchronization bug causing accumulation of zombie processes fixed.
|
|
- Race condition in pthread_cond_timedwait fixed.
|
|
- Recursive mutexes are back by popular demand.
|
|
- Partial support for realtime scheduling (initiated by Richard Neitzel).
|
|
- pthread.h cleaned up a lot: now C++ compatible, added missing "const"
|
|
qualifiers, added short documentation, put to GNU libc standards
|
|
for name space pollution (Ulrich Drepper).
|
|
- Motorola 68k port (contributed by Andreas Schwab).
|
|
- Interaction with fork(2) cleaned up a lot.
|
|
|
|
Release 0.3:
|
|
- Thread creation and reclaimation now performed by a centralized
|
|
"thread manager" thread.
|
|
- Removed recursive mutexes to make regular mutexes more efficient.
|
|
- Now available as a shared library (contributed by Richard Henderson).
|
|
- Alpha port (contributed by Richard Henderson).
|
|
- Fixed many small discrepancies with Posix 1003.1c.
|
|
- Put under the LGPL instead of the GPL.
|
|
|
|
Release 0.2:
|
|
- Reentrant libc functions (adapted from libc 5.3.9 by Peeter Joot)
|
|
- pthread_cond_wait did not reacquire the mutex correctly on return
|
|
- More efficient pthread_cond_broadcast
|
|
|
|
Release 0.1:
|
|
- First public release
