  • Mega patch merge to change the format of the object IDs to loosen the dependency between the SCORE and the various APIs. There was considerable work to simplify the object name management and it appears that the name_table field is no longer needed. This patch also includes the addition of the internal mutex which is currently only used to protect some types of allocation and deallocation. This significantly can reduce context switch latency under certain circumstances. In particular, some heap/region operations were O(n) and had dispatching disabled. This should help enormously. With this merge, the patch is not as clean as it should be. In particular, the documentation has not been modified to reflect the new object ID layout, the IDs in the test screens are not updated, and _Objects_Get_information needs to be a real routine not inlined. As part of this patch a lot of MP code for thread/proxy blocking was made conditional and cleaned up.
  • include/rtems/posix/key.h, src/cond.c, src/condinit.c, src/intr.c, src/key.c, src/keycreate.c, src/keydelete.c, src/killinfo.c, src/mqueue.c, src/mqueuecreatesupp.c, src/mutex.c, src/mutexinit.c, src/psignal.c, src/pthread.c, src/semaphore.c, src/semaphorecreatesupp.c: Modified as part of above.

35
36        * configure.ac: Remove references to RTEMS_BSP.
37        * src/Makefile.am: Add libposix.a.
38
392002-06-17      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
40
41        * include/Makefile.am: Include $(top_srcdir)/../automake/*.am.

46        * src/Makefile.am: Include $(top_srcdir)/../automake/*.am.
47
482001-05-17      Joel Sherrill <joel@OARcorp.com>
49
50        * macros/rtems/posix/mqueue.inl: Implemented missing routines
51        to support message queue FDs.
52
532002-05-03      Ralf Corsepius <corsepiu@faw.uni-ulm.de>       
54
55        * include/sys/utsname.h: Remove.
56        * include/Makefile.am: Reflect changes above.
57        * src/utsname.c: Remove.
58        * src/Makefile.am: Reflect changes above.
59
602001-04-26      Joel Sherrill <joel@OARcorp.com>
61
62        * include/rtems/posix/mqueue.h, inline/rtems/posix/mqueue.inl,

64        src/mqueuegetattr.c, src/mqueuenotify.c, src/mqueueopen.c,
65        src/mqueuerecvsupp.c, src/mqueuesendsupp.c, src/mqueuesetattr.c:
66        Per PR81 reworked to add a message queue descriptor separate from
67        the underlying message queue.  This allows non-blocking to follow
68        the "open" not the underlying queue.
69 
702002-04-06      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
71
72        * src/psignal.c: Include <stdlib.h>.

77        * src/pthread.c (_POSIX_Threads_User_extensions): Reflect above.
78
792002-04-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
80
81        * src/getegid.c: Remove <errno.h>.
82        * src/geteuid.c: Ditto.
83        * src/getgid.c: Ditto.
84        * src/getuid.c: Ditto.

88
89        * configure.ac:
90        AC_INIT(package,_RTEMS_VERSION,_RTEMS_BUGS).
91        AM_INIT_AUTOMAKE([no-define foreign 1.6]).

97
982002-03-01      Eric Norum <eric.norum@usask.ca>
99
100        * src/pthreadonce.c: Task is not preemptable while running a
101        pthread_once init function.  This is slightly less heavy handed
102        than disabling dispatching and seems better than consuming a mutex.
103
1042002-02-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

115
116        * inline/rtems/posix/mutex.inl (_POSIX_Mutex_Get_support): Corrected
117        name of routine in header.
118

167        * include/Makefile.am: Use 'PREINSTALL_FILES ='.
168        * inline/rtems/posix/Makefile.am: Use 'PREINSTALL_FILES ='.
169        * macros/rtems/posix/Makefile.am: Use 'PREINSTALL_FILES ='.
170

179
1802001-09-13      Joel Sherrill <joel@OARcorp.com>
181
182        * src/mprotect.c: New file. Stub required by some gcc's to pass tests.

192
1932001-08-16      Joel Sherrill <joel@OARcorp.com>
194

196        core send operation.
197
1982001-08-09      Joel Sherrill <joel@OARcorp.com>
199
200        * src/mqueuesendsupp.c: Unblocking message queue operations should
201        NOT use _Thread_Executing for return status since it is permissible
202        to invoke message send operations from an ISR.  This was reported
203        by Suvrat Gupta <suvrat@utstar.com>.
204
2052000-05-24      Fernando Ruiz Casas <fernando.ruiz@ctv.es>
206
207        * src/getegid.c, src/geteuid.c, src/getgid.c, src/getlogin.c,

221        include/sys/Makefile.am, inline/rtems/posix/Makefile.am,
222        macros/rtems/posix/Makefile.am:
223        Apply include_*HEADERS instead of H_FILES.

235
2362001-01-12      Joel Sherrill <joel@OARcorp.com>

241
2422001-01-22      Michael Hamel <mhamel@adi.co.nz>
243
244        * include/rtems/posix/semaphore.h, inline/rtems/posix/semaphore.inl,
245        src/ptimer1.c, include/rtems/posix/semaphore.h,
246        inline/rtems/posix/semaphore.inl, src/alarm.c, src/ptimer1.c,
247        src/semaphorenametoid.c, src/semopen.c, src/semunlink.c:
248        Modifications to make CodeWarrior happy.

265
266        * include/rtems/posix/cond.h: #if 0'ed out prototype of

275        macros/rtems/posix/mutex.inl, macros/rtems/posix/priority.inl,
276        macros/rtems/posix/pthread.inl, macros/rtems/posix/semaphore.inl,
277        macros/rtems/posix/timer.inl: New files.
278        * configure.in: Removed error check for enabling macros.
279        * rtems/posix/mutex.h: #if 0'ed out prototypes for inlined routines
280        since you cannot have prototypes for macros.
281        * macros/rtems/posix/Makefile.am: Added files.
282
2832000-11-30      Joel Sherrill <joel@OARcorp.com>
284
285        * inline/rtems/posix/mqueue.inl: Removed explicit dependency on abs().

302
3032000-10-30      Joel Sherrill <joel@OARcorp.com>
304
305        * include/Makefile.am: Updated to reflect files merged into newlib.
306        This resulted in some definitions moving to other files and thus
307        some secondary effects in RTEMS source code.
308        * include/unistd.h: Removed.  Now use newlib's.
309        * include/rtems/posix/mqueue.h: Add include of <signal.h>.

313        * src/execvp.c: Corrected prototype to agree with newlib.
314        * src/psignal.c: Rewrote reference to <siginfo.h> in comment since
315        that file no longer exists.
316        * src/pthreadkill.c: Added include of <signal.h>.
317        * src/sigaction.c: Added include of <signal.h>.
318        * src/sigtimedwait.c: Rewrote reference to <siginfo.h> in comment since
319        that file no longer exists.
320
3212000-10-25      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
322
323        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros.

327
328        * src/Makefile.am, optman/Makefile.am: Include compile.am.
329
3302000-08-30      Joel Sherrill <joel@OARcorp.com>
331
332        * Many files: Moved posix/include/rtems/posix/seterr.h to
333        score/include/rtems/seterr.h so it would be available within
334        all APIs.
335
3362000-08-25      Joel Sherrill <joel.sherrill@OARcorp.com>
337

339        inline/rtems/posix/Makefile.am, src/ptimer1.c: Redid the
340        style of src/ptimer1.c.  Continued effort to make the
341        POSIX Timer implementation match that of other managers.
342        Added data structures required to use SuperCore Object Handler.
343
3442000-08-15      Joel Sherrill <joel@OARcorp.com>
345
346        * src/ptimer1.c: Minor formatting fixes.
347
3482000-08-15      Joel Sherrill <joel@OARcorp.com>
349
350        * src/ptimer1.c: Removed unused routine PRINT_ERRNO_S.
351        * src/ptimer1.c: Removed unnecessary routine COPY_ITIMERSPEC_S

353        * src/ptimer1.c: Renamed timer_alive_t to POSIX_Timer_Control.
354        * include/rtems/posix/timer.h: Ditto.
355

359        to ensure that errno was always set.
360
3612000-08-15      Joel Sherrill <joel@OARcorp.com>
362
363        * src/ptimer1.c (timer_settime): Converted use of rtems_clock_get
