- modifier code was using sizeof() without knowing the sizeof the array when clearing the modifier type array.
- use BLI_snprintf rather then sprintf where the size of the string is known.
- particle drawing code kept a reference to stack float values (not a problem at the moment but would crash if accessed later).
double click didnt check mouse distance moved so you could click twice in different areas of the screen very fast and generate a double click event which had old mouse coords copied into it but was sent to an operator set to run on single click (because the double click wasnt handled).
Also added MEM_name_ptr function (included in debug mode only), prints the name of allocated memory.
used for debugging where events came from.
replaces another so it can do updates (e.g. dopesheet editor can
sync channel selection).
Also coded a simple optimization for allocating small objects,
based on mempools. It's #ifdef'd out, you can enabled it by
defining OPTIMIZE_SMALL_BLOCKS (e.g. adding -DDOPTIMIZE_SMALL_BLOCKS to
your compiler flags).
We suffer from a great deal of performance loss from the system allocator
(vgroups, ghash, edgehash, the singly-linked list implementation in blenlib,
editmesh, and likely a great many areas I'm forgetting), and this is the
common solution for handling the many-small-objects problem. It's not
really production-ready yet (it's long-term memory consequencers need to
be profiled first, and the implementation tweaked as necassary), but for
people on systems with slow system allocators it's worth trying.
Note that since this creates a guardedalloc<->blenlib link, the build systems
need to be updated accordingly (I've already done this for scons, though I'm
not sure if the player builds).
* Rendering twice or more could crash layer/pass buttons.
* Compositing would crash while drawing the image.
* Rendering animations could also crash drawing the image.
* Compositing could crash
* Starting to rendering while preview render / compo was
still running could crash.
* Exiting while rendering an animation would not abort the
renderer properly, making Blender seemingly freeze.
* Fixes theoretically possible issue with setting malloc
lock with nested threads.
* Drawing previews inside nodes could crash when those nodes
were being rendered at the same time.
There's more crashes, manipulating the scene data or undo can
still crash, this commit only focuses on making sure the image
buffer and render result access is thread safe.
Implementation:
* Rather than assuming the render result does not get freed
during render, which seems to be quite difficult to do given
that e.g. the compositor is allowed to change the size of
the buffer or output different passes, the render result is
now protected with a read/write mutex.
* The read/write mutex allows multiple readers (and pixel
writers) at the same time, but only allows one writer to
manipulate the data structure.
* Added BKE_image_acquire_ibuf/BKE_image_release_ibuf to access
images being rendered, cases where this is not needed (most
code) can still use BKE_image_get_ibuf.
* The job manager now allows only one rendering job at the same
time, rather than the G.rendering check which was not reliable.
* removed radiosity render code, DNA and RNA (left in radio render pass options), we'll get GI to replace this probably, better allow baking to vertex colors for people who used this.
* removed deprecated solid physics library, sumo integrations and qhull, a dependency
* removed ODE, was no longer being build or supported
* remove BEOS and AMIGA defines and references in Makefiles.

Notes:
* Game and sequencer RNA, and sequencer header are now out of date
a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
not needed anymore.
* Fix "duplicate strip" always increase the user count for ipo.
* IPO pinning on sequencer strips was lost during Undo.
the features that are needed to run the game. Compile tested with
scons, make, but not cmake, that seems to have an issue not related
to these changes. The changes include:
* GLSL support in the viewport and game engine, enable in the game
menu in textured draw mode.
* Synced and merged part of the duplicated blender and gameengine/
gameplayer drawing code.
* Further refactoring of game engine drawing code, especially mesh
storage changed a lot.
* Optimizations in game engine armatures to avoid recomputations.
* A python function to get the framerate estimate in game.
* An option take object color into account in materials.
* An option to restrict shadow casters to a lamp's layers.
* Increase from 10 to 18 texture slots for materials, lamps, word.
An extra texture slot shows up once the last slot is used.
* Memory limit for undo, not enabled by default yet because it
needs the .B.blend to be changed.
* Multiple undo for image painting.
* An offset for dupligroups, so not all objects in a group have to
be at the origin.
Notes:
- edgehash.c still has some weirdo code causing warnings on lines 80 and 117
i.e. if (v1<v0) v0 ^= v1 ^= v0 ^= v1;
- material.c (in pyapi) apparently doesn't seem to be making use of some functions for glossy stuff
WINDOWS CRASH EMULATION!
If you use the -d (debug) argument for starting blender, it will now:
- set all freed memory to 0xFFFFFFFF
- set all malloced memory to 0xFFFFFFFF
The first option will give nice crashers when you read from freed memory.
The second option is for OSX especially, it has the nasty habit to give
zeroed mallocs.
module itself, replacing the special MEM_mallocT/MEM_freeT functions.
Mutex locking is only enabled when threads are running.
There was no good reason to have these separate, it just led to ugly
hacks when calling functions with non-threadsafe malloc from threads.
- patch from Douglas with endian fixes
- Makefile adds static libiconv.a from lib/
- this version will use OpenEXR libs from lib/ too, and is latest release
with threading support
- openAL is missing, added it as default to not include it
a string as an int and it was causing a warning.
I changed it to check to see if the string == 0
return 0 else return 1.
The only thing that called this function was memtest.c and it
had outdated code, so I fixed that...
was calling MEM_set_error_stream updated to
MEM_set_error_callback
