13 | Release 0.7: |
14 | - Destructors for thread-specific data now conform to the POSIX semantics | |
15 | (call destructors again if non-NULL TSD remains after a round of | |
16 | destruction). | |
17 | - Implemented thread-specific data as a sparse array, allows more TSD keys | |
18 | and smaller thread descriptors (Ulrich Drepper). | |
19 | - Added "error checking" mutexes. | |
20 | - Protect against multiple sigwait() on the same signals. | |
c9326ed5 | 21 | - Simplified implementation of semaphores when compare_and_swap is |
5afdca00 UD |
22 | not available. |
23 | - Fixed bug in fork() where stdin was closed if fork() was called before | |
24 | the first pthread_create(). | |
25 | - Fixed bug in the gethostby*_r functions (bad result if null bytes | |
26 | in addresses). | |
27 | - Typos in manual pages corrected. | |
28 | - First cut at a PowerPC port (not working yet, runs into problems | |
29 | with gcc and with the C library). | |
30 | ||
31 | Release 0.6: | |
32 | - Validation of thread identifiers: no more crashes when operating on | |
33 | a thread that has exited (based on Pavel Krauz's ideas). | |
34 | - Added fallback implementation of semaphores for the 386 and the | |
c9326ed5 | 35 | Sparc. |

36 | - Fixed a bug in signal handling causing false restarts of suspended |
37 | threads. | |
38 | - Fixed a bug in realtime scheduling causing all threads to have | |
39 | default scheduling on Ix86 with libc5. | |
40 | - With realtime scheduling, unlocking a mutex now restarts the | |
41 | highest priority thread waiting on the mutex, not the | |
42 | first-suspended thread (Richard Neitzel). | |
43 | - Timing a process now returns cumulative times for all threads, not | |
44 | just times for the initial thread (suggested by Wolfram Gloger). | |
45 | - Cleaned up name space (internal defs prefixed by __, weak aliases | |
46 | for non-portable extensions). | |
47 | - MIPS port (contributed by Ralf Baechle). | |
48 | ||
49 | Release 0.5: | |
50 | - Signal-safe semaphores a la POSIX 1003.1b added. | |
51 | - Locking bug in pthread_mutex_trylock over recursive mutexes fixed. | |
52 | - Race conditions in thread cancellation fixed. | |
53 | - Sparc port (contributed by Miguel de Icaza). | |
54 | - Support for getpwnam_r and getpwuid_r. | |
55 | - Added pthread_kill_other_threads_np to be used in conjunction with | |
56 | exec*(). | |
57 | ||
58 | Release 0.4: | |
59 | - Manual pages for all functions. | |
60 | - Synchronization bug causing accumulation of zombie processes fixed. | |
61 | - Race condition in pthread_cond_timedwait fixed. | |
62 | - Recursive mutexes are back by popular demand. | |
63 | - Partial support for realtime scheduling (initiated by Richard Neitzel). | |
c9326ed5 | 64 | - pthread.h cleaned up a lot: now C++ compatible, added missing "const" |
5afdca00 UD |
65 | qualifiers, added short documentation, put to GNU libc standards |
66 | for name space pollution (Ulrich Drepper). | |
67 | - Motorola 68k port (contributed by Andreas Schwab). | |
68 | - Interaction with fork(2) cleaned up a lot. | |
69 | ||
70 | Release 0.3: | |
71 | - Thread creation and reclaimation now performed by a centralized | |
72 | "thread manager" thread. | |
73 | - Removed recursive mutexes to make regular mutexes more efficient. | |
74 | - Now available as a shared library (contributed by Richard Henderson). | |
75 | - Alpha port (contributed by Richard Henderson). | |
76 | - Fixed many small discrepancies with Posix 1003.1c. | |
77 | - Put under the LGPL instead of the GPL. | |
78 | ||
79 | Release 0.2: | |
80 | - Reentrant libc functions (adapted from libc 5.3.9 by Peeter Joot) | |
81 | - pthread_cond_wait did not reacquire the mutex correctly on return | |
82 | - More efficient pthread_cond_broadcast | |
83 | ||
84 | Release 0.1: | |
85 | - First public release |
