* When making a proxy, the lib linked IPO driver was also changed to
point to the proxy object, and after undo this local proxy object
was replaced so the pointer became invalid. In fact it is not needed
at all to change this because the IPO code maps the pointer to the
local proxy object already.
* Undoing the make proxy operation would crash because the proxy_from
pointer in the library linked object would still point to the removed
object. Now it clears all these pointers before undo, because on each
undo memory file read they will be set again anyway.
The good news; previously written 64 bits are still valid! All fixes
appeared to be possible in code, no versioning patches needed. :)
That also removes the I AM STUPID 64 bits ban from the code.
The bad news:
I couldn't get a 64 bits Blender running here (ghost-mac issues... it
has to be recoded using Quartz to be able to run 64 bits). So what I
have tested was:
32 bits binary:
- Appending/linking data from 64 bits file.
- Reading 64 bits chained library-linked files (file -> file -> etc)
- Linking 32 bits files with 64 bits files
This has to be tested for 64 bits too. Will drop in IRC now to help.
Note: part 3 is fixing memory issues for addressing > 4 GB data. A first
start has been made for a blenlib API function.
Next to the release code, a subversion number is written in the file
now. This is in the chunk GLOB, which is now in beginning of file.
Subversions can be used to have finer control over do_versions(), so you
don't have to wait for a release to patch stuff nicely. We can also
increase these subversions regularly to denote important changes.
If a subversion is not 0, it's being printed in the header, so a user can
also verify the state. (We might even tag cvs for it?).
Next to this, a minimum version and subversion number are written too.
From now on, if you change files in a way a past binary cannot read this
nicely anymore, you should set these minima to the current version.
This was especially added for the new mesh layers, which will not work
for older binaries once we make 2.43.
library .blend files anymore, making it a load faster to use.
- Fixed ancient annoyance; samples were not properly freed, giving a lot
"Error Totblock" when using sound.
This fix also involves removing an ancient NaN hack, which treated the
samples as fake Library data in the Main database.
But still, the Blender Sound and Sample code is horrible... :/
Was surprisingly easy to add, compiant with file reading and undo code.
Currently only the Image->ibuf gets restored, and its opengl binding, so
for realtime texture it works nicely. Also texture images are not freed
inbetween undo steps
Notes:
- Painting textures will just keep the painted image, there's no undo
yet for that
- If this works satisfying, I'll extend it to compositing previews
TEST IT WELL PLEASE! :)
He even made a nice doc in wiki:
http://wiki.blender.org/bin/view.pl/Blenderdev/Blendgz
Usage: set the option "Compress File" in the main "File" pulldown menu.
This setting is a user-def, meaning it is not changed on reading files.
If you want it default, save it with CTRL+U.
The longest debate went over the file naming convention. Shaul started
with .blend.gz files, which gave issues in Blender because of the code
hanging out everywhere that detects blender files, and that appends the
.blend extension if needed.
Daniel Dunbar proposed to just save it as .blend, and not bother users
with such details. This is indeed the most elegant solution, with as
only drawback that old Blender executables cannot read it.
This drawback isn't very relevant at the moment, since we're heading
towards a release that isn't upward compatible anyway... the recode
going on on Meshes, Modfiers, Armatures, Poses, Actions, NLA already
have upward compatibility issues.
We might check - during the next month(s) - on a builtin system to
warn users in the future when we change things that make a file risky
to read in an older release.
Appending from files also set the string for "last loaded file". That's
a real bad one... so you can save over accidentally libraries.
Another fix: appending from files that have dynamic other files linked
with relative paths didn't work. (Yah, now it should all work!)
renderconverter change is just a more clear comment.
- file-to-memory save
- incremental difference steps (compression)
everthing has been tightly coded to use minimum of memcpy or allocs. In
fact this system works with a single full buffer (=file) in memory, and undosteps as differences from it.
Speed gain is factor 4-8 faster. I've added it in CTRL+ALT+T timer menu for
a test. Please note the gain is especially in the undo-storing, not in
retrieving undo.
Also new: file read option to skip UI read (file menu). This now also is
default for the undo system.
(adding)
#ifdef HAVE_CONFIG_H
#include <config.h>
#endif
also the Makefile.in's were from previous patch adding
the system depend stuff to configure.ac
