c0f8e15295 Speedup for guarded allocator 
- Re-arrange locks, so no actual memory allocation
  (which is relatively slow) happens from inside
  the lock. operation system will take care of locks
  which might be needed there on it's own.

- Use spin lock instead of mutex, since it's just
  list operations happens from inside lock, no need
  in mutex here.

- Use atomic operations for memory in use and total
  used blocks counters.

This makes guarded allocator almost the same speed
as non-guarded one in files from Tube project.

There're still MemHead/MemTail overhead which might
be bad for CPU cache utilization

58d7ae891d Blender might be compiled without guardedalloc again 
This is useful for benchmark tests, to make CPU cache
utilization as good as we could with current design.

ce2e2b141e use gcc malloc attribute for low level allocation functions, prevents gcc from checking if resulting pointers alias existing pointers, also use sentinel attribute for uiButGetStrInfo so incorrect usage gives a warning. 2013-08-05 20:57:13 +00:00

bd89bd9e1c avoid using MEM_reallocN_id directly, add utility macro for freeing. 2013-08-04 03:00:04 +00:00
Campbell Barton
2a8d76d734 add versions of MEM_reallocN, MEM_recallocN which take a string arg so new allocs have an ID, changing existing functions signatures would be too disruptive at the moment. 2013-08-03 17:53:41 +00:00

fe02323632 Fix to actually disable DEBUG_BACKTRACE by default. 2013-05-31 12:36:35 +00:00
Sergey Sharybin
1be2936298 Backtrace for unfreed memory blocks 
Added an option to show backtrace from where
non-freed datablock was allocated from.

To enable this feature, simply enable DEBUG_BACKTRACE
in mallocn.c file and all unfreed datablocks will
be followed up by a backtrace.

Currently works on linux and osx only,
windows support is on TODO.

This feature is for sure disabled by default,
so does not affect any builds which don't
explicitly define DEBUG_BACKTRACE.

225c5fee6b move BLO_sys_types.h -> BLI_sys_types.h (it had nothing todo with loading) 
remove MEM_sys_types.h which was a duplicate.

cd6b27f2b5 remove return value from MEM_freeN, it wasn't used anywhere and was cast to a different function signature. (which evidently works but error prone). 2013-05-21 07:37:59 +00:00

7b707fff56 correct assert for driver evaluation, 
also add asserts for listbase functions when the list is NULL, and use noreturn attribute for jpeg_error.

7d4eee2b18 add option to disable guardedalloc, helps for debugging memory errors 
since guardedalloc confuses them.

The option cases a warning on build, since its ownly for experimental
use.

9d36fade8f make MEM_reallocN and MEM_recallocN behave as libc's realloc() - alloc when receiving a NULL value. 2013-01-27 11:20:50 +00:00

5e739ddae2 Added some code which helps troubleshooting issues caused by 
non-threadsafe usage of guarded allocator.

Also added small chunk of code to check consistency of begin/end
threaded malloc.

All this additional checks are commented and wouldn't affect on
builds, however found them helpful to troubleshoot issues so
decided to commit it to SVN.

6571713ddb Ambient occlusion baker from multi-resolution mesh 
This implements AO baking directly from multi-resolution mesh with much
less memory overhead than regular baker.

Uses rays distribution implementation from Morten Mikkelsen, raycast
is based on RayObject also used by Blender Internal.

Works in single-thread yet, multi-threading would be implemented later.

Also changed shebang to '#!/usr/bin/env python', this is more portable across unixes...

60808c5ed6 disable openmp thread assert, would fail in cases where the caller was locking for its self (sculpt mode) 2012-12-13 10:37:04 +00:00
Campbell Barton
21a2660290 assert in debug builds if MEM_ alloc's are called in openmp threads. 
note: the caller can do locking to prevent errors - but this isn't being done in blender yet, so this prevents accidental allocs in openmp for now.
