It was intended to work actually using particle cache's stack index
but this index might have been calculated incorrect in special case:
* With default cube scene, add particle system to the cube
* Add disk cache to the particle system
* Save file and reload it
* Add another particle system and enable disk cache
This would lead to two point caches with the same stack index of zero.
This happened because point cache indices list wasn't stored in the
.blend file so once you've reload your file blender doesn't know anything
about number or point caches used.
And what was even more confusing is that point cache indices list was
trying to be load from the file, but this failed because it wasn't in the
file.
This commit solves the root of the issue which is ability of producing
.blend file with two point caches using the same disk cache. This is
done by making it sure that point cache indices list is stored in the
.blend file. And also made it so disabling disk cache will tag it to
recalculate stack index.
Old broken files wouldn't magically start working, but fixing them is
rather simple manually by toggling Disk Cache option.

FileGlobal structure in write_global() didn't initialize
the while build_hash property and only placed there null
terminated meaningful content, leaving trailing uninitialized.
This made valgrind complain about using uninitialized memory
later in undo stack.
This adds an ImageUser to such empties with all the typical settings.

EditFont's use of Curve.len was very confusing, in editmode it
represented the number of characters, in object mode the number of
bytes. add Curve.len_wchar and keep track of both.
Also don't convert the editmode text into utf8 on every keystroke.
Now this is done on exiting editmode or save - to match most other
object types.
This also fixes curves 'body_format' being reported with an invalid size.
Levels of detail can be added and modified in the object panel. The object
panel also contains new tools for generating levels of detail, setting up
levels of detail based on object names (useful for importing), and
clearing an object's level of detail settings. This is meant as a game
engine feature, though the level of details settings can be previewed in
the viewport.

- works by defining panel categories, currently restricted to the toolbar.
- no panels define bl_categories yet, so no user visible changes since tabs only show when there are multiple.
- panel pinning is available in rmb menu or alt+lmb.
Summary:
Old idea with changes since previous release tag
didn't work good enough. In most of the cases tag
was done in a branch hence not actually reachable
from the master branch.
Now change since release is gone, and date of
the latest commit is used instead.
The date is displayed in format YYYY-MM-DD HH:mm
in the splash.
New bpy.app fields:
- build_commit_timestamp is an unix timestamp of
the commit blender was build from.
- build_commit_date is a date of that commit.
- build_commit_time is a time of that commit.

- Use commit number since last annotated tag as a
revision number replacement. It'll eb followed
by 'M' symbol if there're local modification in
the source tree.
- Commit short SHA1 is included. Helps getting
information about commit used to build blender
with much faster.
- If build is not done from master branch, this also
will be noticed in the splash screen.
This commit also replaces revision stored in the
files with git-specific fields (change and hash).
This is kind of breaks compatibility, meaning
files which were saved before this change wouldn't
display any information about which revision they
were saved with. When we'll finally switch to git,
we'll see proper hash and change number since
previous release in the files, for until then
svn version will be used as a change number and
hash will be empty.
Not a huge deal, since this field was only used
by developers to help torubleshooting things and
isn't needed for blender itself.
Some additional tweaks are probably needed :)
Thanks to Brecht for the reviews. :)
This commit adds a show/hide extension below each uiList, containing by default an option to filter and/or reorder items by name (and to reverse those filtering and reordering).
Each derived uiList class in Python can define more specific filtering by implementing callbacks: the draw_filter() function to draw options in UI, and the filter_items() function to effectively filter/reorder items.
Note: the advanced options for vgroups shown as "proof od concept" in patches do not go in trunk for now, we have to find a better way to get those vgroups info for UI code, we can't afford to loop over each vertex here!
And doc (release notes and uiList example) is still to be updated, will do this in next days.
This commit includes all the changes made for plane tracker
in tomato branch.
Movie clip editor changes:
- Artist might create a plane track out of multiple point
tracks which belongs to the same track (minimum amount of
point tracks is 4, maximum is not actually limited).
When new plane track is added, it's getting "tracked"
across all point tracks, which makes it stick to the same
plane point tracks belong to.
- After plane track was added, it need to be manually adjusted
in a way it covers feature one might to mask/replace.
General transform tools (G, R, S) or sliding corners with
a mouse could be sued for this. Plane corner which
corresponds to left bottom image corner has got X/Y axis
on it (red is for X axis, green for Y).
- Re-adjusting plane corners makes plane to be "re-tracked"
for the frames sequence between current frame and next
and previous keyframes.
- Kayframes might be removed from the plane, using Shit-X
(Marker Delete) operator. However, currently manual
re-adjustment or "re-track" trigger is needed.
Compositor changes:
- Added new node called Plane Track Deform.
- User selects which plane track to use (for this he need
to select movie clip datablock, object and track names).
- Node gets an image input, which need to be warped into
the plane.
- Node outputs:
* Input image warped into the plane.
* Plane, rasterized to a mask.
Masking changes:
- Mask points might be parented to a plane track, which
makes this point deforming in a way as if it belongs
to the tracked plane.

This is mine and Keir's holiday code project :)
with recent outliner optimizations (revision 58855, 3 days ago), in any Blender
version before this commit. On current Blender it would give a double free
warning in the console.
The problem is that it creates a temporary TreeStore on file save. However if you
have multiple outliners this memory block would always be at the same memory
address making it no longer unique. That then meant old memory address lookups on
file read were failing. Solution now is to postpone freeing these temporary memory
blocks until the end so that they are at unique addresses.
- performance of outliner was low because of unoptimal data structures.
- now it uses BLI_mempool instead of custom mempool and GHash to make searches for duplicates faster.
- also fix undesired behaviour of BLI_mempool_as_arrayN
thanks to Campbell Barton and Lukas Tönne for helping me get a better fix put together.
the way Curve.len is used at the moment is really stupid, calculate string size on save for now, but should really store the length in bytes and total number of characters.
code was modifying pointers in the Mesh which gave crashes with another thread
accessing the data at the same time. This could crash other threaded operations
like blender internal render or physics baking too but was less likely.
As a solution I've now changed the save code that it does not modify the mesh
data structure in place but rather a copy, as undo file saving should probably
be fully read-only regardless of how an improved threading architecture might
work.
Thanks to Sergey for tracking down the cause of this crash.

and RNA for it independent of the build flag for enabling Freestyle. Suggested
by Sergey Sharybin through a code review of the branch.
* Many #ifdef WITH_FREESTYLE blocks were removed to always have Freestyle-specific
DNA file specification and RNA for it built in Blender. This will allow Freestyle
setting survive even when a non-Freestyle build is used for loading and saving
files. It is noted that operations are still conditionally built through #ifdef
WITH_FREESTYLE blocks.
* To this end, new blenkernel files BKE_freestyle.h and intern/freestyle.c have
been added. All API functions in FRS_freestyle_config.h as well as some of those
in FRS_freestyle.h were moved to the new files. Now the relocated API functions
have BKE_ prefix instead of FRS_.
The problem here was that the extra forward compatibility data for node groups (links to the node interface sockets) was written for files as well as undo memfiles. But only in the case of true .blend files is this data subsequently removed again after loading, which in the case of undo leaves invalid links hanging around in the node tree. Forward compat data is now skipped for undo.
PyNodes opens up the node system in Blender to scripters and adds a number of UI-level improvements.
=== Dynamic node type registration ===
Node types can now be added at runtime, using the RNA registration mechanism from python. This enables addons such as render engines to create a complete user interface with nodes.
Examples of how such nodes can be defined can be found in my personal wiki docs atm [1] and as a script template in release/scripts/templates_py/custom_nodes.py [2].
=== Node group improvements ===
Each node editor now has a tree history of edited node groups, which allows opening and editing nested node groups. The node editor also supports pinning now, so that different spaces can be used to edit different node groups simultaneously. For more ramblings and rationale see (really old) blog post on code.blender.org [3].
The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout. Internal sockets can be exposed from a group by either connecting to the extension sockets in input/output nodes (shown as empty circle) or by adding sockets from the node property bar in the "Interface" panel. Further details such as the socket name can also be changed there.

Saving and loading gpencil was using different order for the individual list items.
On a 120 Mb gpencil project (yes, animators!) loading time went down from 1 minute
to a second or two.
Note that this to have effect, you need to save once.
Developer note: check this commit, it uses a new writelist function. You can
speedup stuff tremendously with keeping saved and read data in sync.
