* refactor copying and freeing of node->storage by handlerizing them.
- freestoragefunc
- copystoragefunc
- node_util.c/h have generic handlers for these.
Crashes in composite; caused by bad bad bug in freeing "passed on" buffers,
only happens with option "Free unused" set though.
Appeared to be mixup of variable names. Code changes with 2 bytes... :)
Works simple; just check for
if(node->exec & NODE_BREAK)
break;
The main process (node processor) sets such a flag, checking for esc
20 times per second. That means you can check for ESC while doing image
processing without much cpu overhead.
Currently only added in blur nodes and defocus. Needs to be added all over,
nice for others... needs careful tests too.
What we now could do is even calling ESC on editing commands or mouseclicks
in composite editor? Could give user feeling of interactive app :) Further,
finished nodes are kept in memory anyway.
This will allow python or plugin defined nodes to work as well.
(And fixes compile issues with MSVC in yesterdays commit for nodes)
Code provided by Nathan L.
Fixes in his code:
- free_nodesystem() was called too late (after guarded alloc was closed)
- free_nodesystem() was freeing nodes that were not malloced even
- free_nodesystem was using free, not freeN :)
- the typedefs needed to be malloced yes, to allow duplicate nodes like
group but also for dynamic nodes.
- removed all UI .h include stuff! (Not allowed outside of src/)
- Makefile had typo error, compilation failed
Now it survives make, but it does not enter the two the subdirectories for
shader and compo nodes. So a linking gives unrecovered stuff in the end.
How does that work? I need help!
