From a9f5aa1cc96fc2c71f19a9c3e9dcbee0e78f83ca Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Tue, 15 Nov 2005 03:13:04 +0000 Subject: rename current stable linuxthreads to linuxthreads.old to prepare for import of latest glibc version --- libpthread/linuxthreads.old/Changes | 85 +++++++++++++++++++++++++++++++++++++ 1 file changed, 85 insertions(+) create mode 100644 libpthread/linuxthreads.old/Changes (limited to 'libpthread/linuxthreads.old/Changes') diff --git a/libpthread/linuxthreads.old/Changes b/libpthread/linuxthreads.old/Changes new file mode 100644 index 000000000..b213f36c5 --- /dev/null +++ b/libpthread/linuxthreads.old/Changes @@ -0,0 +1,85 @@ +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 -- cgit v1.2.3
