The problem is that realloc() can neither grow nor shrink efficiently the current memory region without support from underlying heap/region modules. The patch introduces one new routine for each of heap and region modules, _Heap_Resize_block(), and rtems_region_resize_segment(), respectively, and uses the latter to optimize realloc(). The implementation of _Heap_Resize_block() lead to changing of the heap allocation strategy: now the heap manager, when splits larger free block into used and new free parts, makes the first part of the block used, not the last one as it was before. Due to this new strategy, _Heap_Resize_block() never needs to change the user pointer. Caveat: unlike previous heap implementation, first few bytes of the contents of the memory allocated from the heap are now almost never all zero. This can trigger bugs in client code that have not been visible before this patch. * libcsupport/src/malloc.c (realloc): try to resize segment in place using new rtems_region_resize_segment() routine before falling back to the malloc()/free() method. * score/src/heap.c: (_Heap_Initialize): change initial heap layout to reflect new allocation strategy of using of the lower part of a previously free block when splitting it for the purpose of allocation. (_Heap_Block_allocate): when split, make the lower part used, and leave the upper part free. Return type changed from Heap_Block* to uint32_t. * score/include/rtems/score/heap.h: (Heap_Statistics): added 'resizes' field. (Heap_Resize_status): new enum. (_Heap_Resize_block): new routine. (_Heap_Block_allocate): return type changed from Heap_Block* to uint32_t. * score/src/heapwalk.c: reflect new heap layout in checks. * score/src/heapsizeofuserarea.c: more assertions added. * score/src/heapresizeblock.c: new file. (_Heap_Resize_block): new routine. * score/src/heapfree.c: reverse the checks _Heap_Is_block_in() and _Heap_Is_prev_used() on entry to be in this order. * score/src/heapallocate.c, score/src/heapallocatealigned.c: ignore return value of _Heap_Block_allocate(). * score/Makefile.am (HEAP_C_FILES): added src/heapresizeblock.c. * rtems/include/rtems/rtems/region.h: (rtems_region_resize_segment): new interface routine. (_Region_Process_queue): new internal routine called from rtems_region_resize_segment() and rtems_region_return_segment(). * rtems/src/regionreturnsegment.c: move queue management code into the new internal routine _Region_Process_queue() and call it. * rtems/src/regionresizesegment.c: new file. (rtems_region_resize_segment): new interface routine. * rtems/src/regionprocessqueue.c: new file. (_Region_Process_queue): new internal routine containing queue management code factored out from 'regionreturnsegment.c'. * rtems/Makefile.am (REGION_C_FILES): Added src/regionresizesegment.c, and src/regionprocessqueue.c. * ada/rtems.adb, ada/rtems.ads: Added Region_Resize_Segment.

The type for configuring the maximum number of objects should probably always be the same fundamental type as Object Id. For 16-bit Id configurations, the constant OBJECTS_UNLIMITED_OBJECTS was changed to 0x8000 to move in this direction.

Also _Watchdog_Sync_count++ should be protected by _ISR_Disable (prevent corruption in case ISR calls watchdoginsert) * src/watchdogadjust.c: ISR protection added. * src/watchdogtickle.c: ISR protection added. NOTE: PowerPC BSPs using the new exception processing MUST BE UPDATED to maintain _ISR_Nest_level. See also PR288 which provides fixes for the affected BSPs distributed with RTEMS.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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/Makefile.am, include/rtems/score/coremsg.h, include/rtems/score/coremutex.h, include/rtems/score/coresem.h, include/rtems/score/object.h, include/rtems/score/threadq.h, inline/rtems/score/object.inl, inline/rtems/score/thread.inl, macros/rtems/score/object.inl, src/Makefile.am, src/coremsg.c, src/coremutex.c, src/coresem.c, src/mpci.c, src/objectcomparenameraw.c, src/objectextendinformation.c, src/objectinitializeinformation.c, src/objectnametoid.c, src/thread.c, src/threadclose.c, src/threadget.c, src/threadq.c, src/threadqextractwithproxy.c: Modified as part of above. * include/rtems/score/apimutex.h, src/objectgetnoprotection.c: New files.

| | | | | | | | | * include/rtems/score/thread.h, inline/rtems/score/thread.inl, src/threaddispatch.c, src/threadinitialize.c: Move the C library re-enterrant support directly into the thread dispatch code. RTEMS needs libc and so requiring libc to use a user extension with its overhead is not the best solution. This patch lowers the overhead to 2 pointer moves.

| | | | | | | | | | * include/rtems/score/object.h, inline/rtems/score/object.inl, src/objectcomparenamestring.c: Address PR81 that reworked POSIX message queues to add a descriptor separate from the underlying message queue. This allows non-blocking to follow the "open" not the underlying queue. As part of debugging this it became clear that _Objects_Compare_name_string was broken and a simple version using strncmp() was substituted.
