39c3ebdc91 fix for memory leak: node animation data wasnt being free'd
also some corrections to memory debug stuff.

c1ee920db6 simple malloc counter for debugging. disabled so no functional change.
Use when memory isnt being freed to easily set a breakpoint the Nth allocation.

cac3443d4e Guardedalloc: added MEM_reallocN function to do simple alloc/memcpy/free,
not as optimized as a system realloc but I've had to do this often enough
manually to justify a utility function.

0c2d03e69f Fix MEM_testN not unlocking mutex correctly, unlikely to lead to
problems in practice but might as well fix.

7ad7820f7f Added a new notifyer, NC_SPACE_CHANGED, to signal an editor that
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).

f7d7149936 Debug tools: new function MEM_testN(void*)
returns 0 if pointer is not in memlist
2009-11-11 03:45:26 +00:00

21385eb4ec New function:
void MEM_callbackmemlist(void (*func)(void*));

Will call the function passed as argument with all allocated address as parameter. Useful for debuging.

b466286c3e Render & Compositing Thread Fixes
* 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.

Was annoying to use a different editor for cmake only.
theeth says this should be ok with gsoc and merges from branches.

* bring back 'player' libtype, after investigation with ideasman.
  scons/mingw works nicely, for some reason msvc fails to link still, will look further into it.

20f39ec7d8 == SCons ==
* further cleaning of 'player' stuff. Now only 3 libs are remaining, of which ideally the stubs lib will be fixed at some point, fading away into the dark history of not-so-nice code. The current blenderplayer part is still a little bit hackish, I'll see if I can find a better alternative, for now it works good enough.

8ead648fd1 Spring Cleaning
* 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.

c8b4cf9206 2.50:
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD

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.

bdfe7d89e2 Merge of trunk into blender 2.5:
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r12987:17416

Issues:
* GHOST/X11 had conflicting changes. Some code was added in 2.5, which was
  later added in trunk also, but reverted partially, specifically revision
  16683. I have left out this reversion in the 2.5 branch since I think it is
  needed there.
  http://projects.blender.org/plugins/scmsvn/viewcvs.php?view=rev&root=bf-blender&revision=16683
* Scons had various conflicting changes, I decided to go with trunk version
  for everything except priorities and some library renaming.
* In creator.c, there were various fixes and fixes for fixes related to the -w
  -W and -p options. In 2.5 -w and -W is not coded yet, and -p is done
  differently. Since this is changed so much, and I don't think those fixes
  would be needed in 2.5, I've left them out.
* Also in creator.c: there was code for a python bugfix where the screen was not
  initialized when running with -P. The code that initializes the screen there
  I had to disable, that can't work in 2.5 anymore but left it commented as a
  reminder.

Further I had to disable some new function calls. using src/ and python/, as
was done already in this branch, disabled function calls:
* bpath.c: error reporting
* BME_conversions.c: editmesh conversion functions.
* SHD_dynamic: disabled almost completely, there is no python/.
* KX_PythonInit.cpp and Ketsji/ build files: Mathutils is not there, disabled.
* text.c: clipboard copy call.
* object.c: OB_SUPPORT_MATERIAL.
* DerivedMesh.c and subsurf_ccg, stipple_quarttone.

Still to be done:
* Go over files and functions that were moved to a different location but could
  still use changes that were done in trunk.

cb89decfdc Merge of first part of changes from the apricot branch, especially
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.

86a0afb829 Compiler warning fixes (unused vars).
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

b7af3d2cbd fix for [#8257] double-freeing pointers from sculpt code
http://projects.blender.org/tracker/index.php?func=detail&aid=8257&group_id=9&atid=125

Cleaned up scene_copy, and moved some scene copying into this function that was inline in the user interface.

Also moved malloc error prints onto separate lines so you can set breakpoints.

Bugfix #6168

* instead of compiling mallocn manually for makesdna, use the bf_guardedalloc lib
 that was already created looooooong time ago.

6d540b6333 More debug goodies:
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.

e7d6537f1c Added support for threadsafe MEM_mallocN/MEM_freeN in the guardedalloc
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.
