this crash could happen in other situations too, problem was a bug in the
jobs system. A job could be suspended, and the operator would stop before
the job was actually done since it was not marked as running.
This patch adds:
* support for proxy building again (missing feature from Blender 2.49)
additionally to the way, Blender 2.49 worked, you can select several
strips at once and make Blender build proxies in the background (using
the job system)
Also a new thing: movie proxies are now build into AVI files, and
the proxy system is moved into ImBuf-library, so that other parts
of blender can also benefit from it.
* Timecode support: to fix seeking issues with files, that have
a) varying frame rates
b) very large GOP lengths
c) are broken inbetween
d) use different time code tracks
the proxy builder can now also build timecode indices, which are
used (optionally) for seeking.
For the first time, it is possible, to do frame exact seeking on
all file types.
* Support for different video-streams in one video file (can be
selected in sequencer, other parts of blender can also use it,
but UI has to be added accordingly)
* IMPORTANT: this patch *requires* ffmpeg 0.7 or newer, since
older versions don't support the pkt_pts field, that is essential
for building timecode indices.
Windows and Mac libs are already updated, Linux-users have to build
their own ffmpeg verions until distros keep up.
New option to start threaded wmJobs, with flag WM_JOB_SUSPEND.
This makes the job wait 1 timer step before running.
Used now for Material Icon render renders, which makes the
big preview to be always rendered first while using UI.
The icons for materials were always lagging or not updating
at all. I also found it suspicious slow...
It appeared that the icons now store a "mip level", where for
every change in Materials 2 render jobs for icons were started,
one for 32x32 pix, one for 96x96. The latter was cancelling out
the first job almost always.
Also made preview renders detect size, to set amount of tiles
to be rendered. Small icons use 1 part, larger previews 16 now.
All in all, behaves much smoother now! But, will also update
the thread Jobs manager to allow "delayed jobs" like for icons,
these are aggressively put as first in the jobs list.
Displays a global progress indicator in the application icon reflecting the total progress of all running jobs.
Currently fully implemented on OSX (Cocoa).
On other OSes that do not allow to redraw the app icon, this can be implemented as a [x%] display in the app title, so to appear in the taskbar.
Thanks to Matt for the windowmanager wrapper.
Now, rather than the bit-too-alarming stop sign, threaded wmJobs
display a progress indicator in the header. This is an optional feature
for each job type and still uses the same hardcoded ui template
(could use further work here...).
Currently implemented for:
Render - parts completed, then nodes comped
Compositor - nodes comped
Fluid Sim - frames simulated
Texture Bake - faces baked
Example: http://mke3.net/blender/devel/2.5/progress.mov
* Division by zero fix for TNT SVD code.
* Sound fix, in case ffmpeg decode fails, don't use the samples.
* Fix for incorrect bounds of transformed objects in new raytracing code.
* Gave memory arena's a name used for allocations for easier memory
usage debugging.
* Dupligroup no_draw option was using layers but not restrict view/render
setting. (not a bugfix exactly but would do display list context switching
while drawing for no reason).
* Fix objects instanced on hair particles not giving consistent results
when the object is transformed.
* New math functions: madd_v4_v4fl, len_squared_v3v3, interp_v4_v4v4v4,
mul_v4_m4v4, SH and form factor functions, box_minmax_bounds_m4.
* mul_m4_m4m4 and mul_m3_m3m3 now accept the same pointers for multiple
arguments.
* endjob callback for WM jobs system.
* Geometry node uv/color layer now has search list/autocomplete.
* Various small buildsystem tweaks, not strictly needed yet in trunk.
* move own thread handling for thumbnails to WM_jobs
* cleanup of thumbnail creation code
* added function to kill the job, which actually allows thread to terminate gracefully
vc9 projectfiles:
* fixed some missing includes for release target!
Auto save is now working again in 2.5. It will also remember now what
the location of the original file was when recovering it, so that
library links still work and saving the restored file does not save to
the temp directory. There is also a new Recover Auto Save operator
which will open the filebrowser in the temp directory and show the
auto saved .blends.
Implemenation Notes:
* Timer storage was moved from window to windowmanager, so we can have
windowmanager level timers too now, doesn't make sense to have
autosave timer attached to a particular window.
* FileGlobal now has a filename field storing where the file was saved.
Note that this is only used when loading a file through the recover
operators, regular file read doesn't use it, so copying the quit.blend
manually over the original file will still work as expected.
* Jobs timer no longer uses operator now, this seems more like an
internal thing, changing keymaps should not make it possible to break
the jobs manager.
* Autosave is postponed by 10 seconds when a modal operator is running,
e.g. transform or file browsing.
* Moved setting G.sce in setup_app_data before depsgraph updates, these
can use the filename for pointcaches.
* 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.
New feature: allowing to open temporarily windows for output.
Implemented for:
- Render output (use output menu "new window" option).
- User Preferences (alt+U, plus added in 'File' menu)
Currently the window opens where your mouse is. The Render window
works as usual, with ESC or F11 moving it to back or front again.
That allows the window position to remain where you moved it on
new renders.
If you close a render window when it renders, the render thread
will be killed.
User prefs show 'info window' now... i thought we'd use outliner?
Anyhoo, I've made the 'save settings' to close the 2nd window as
well.
Opening a secondary file window for save I'll check on later,
this has to be checked with the current event system still.
the WM_window_open_temp() api call for this maintains currently
a *single* temp window. If you have a render window open, and call
for the preferences, the render window will be used for it. And
the other way around.
On closing the blender window, the temp windows close automatically
when there's no regular window open, and blender quits.
Nice goodie: Preview renders!
- Added new preview.blend, allowing super wide cinemascope previews
- Draws nicely blended inside widget type, rounded corners
- Preview now renders using all available cpus/cores.
- Uses - hopefully rock stable - method, which doesn't copy or
allocate anything for previews, but just uses render API calls.
- Multiple previews are possible! But, added provision in Jobs
manager to only render one preview job at a time. If you start
more preview jobs, they're suspended until it's their turn.
Bugfix: new buttons context code crashed when going full-window.
Tweaks are still needed for notifiers. I have to figure out still
how to retrieve SpaceButs button view types...
Several things in one commit; could not split this up easily,
one job invoked another, and so on. :)
- Added pulldowns for save/load .blend file in top bar.
- To enable "Save" without further popups (save over)
I've added a signaling function in window header to
indicate a succesful save.
- On any undo push it now signals 'file changed'. This
goes by notifiers nicely, but now registers only the
undopushes, which is quite unreliable. "Changed" state
shows in header as "Blender*" and for OSX with the
standard close button black dot.
- Made screencast show a button in top bar indicating such,
and allowing quit. No hotkey for quit yet... but ESC will
keep casting now.
- Fixed new BLF_init(), which should be in WM_init() and not
on any .B.blend read.
- Fixed CTRL+F3 "Save Screenshot", which was still using old
fileselect code.
Compositor now uses threaded jobs.
- updates happen per preview node! Check this file for
fun: http://www.blender.org/bf/composite_image.blend
(any compo node could get preview!)
- had to ensure the composite data gets fully copied before
it executes thread, so editing is not frustrated.
- put back node buttons (missing init)
- added WM_jobs api call to check for running job,
illustrated with red light icon in 'use nodes' button.
- added another callback to WM_jobs, to initialize.
use this init to ensure you only do it when job really
starts.
- added an extra notifier option for WM_jobs, to signal
finished job (like redraw image view)
- fixed file read error, it copied the screen it read,
instead of using it.
- commented out annoying prints for missing ops in imagewin
Added WM Jobs manager
- WM can manage threaded jobs for you; just provide a couple
of components to get it work:
- customdata, free callback for it
- timer step, notifier code
- start callback, update callback
- Once started, each job runs an own timer, and will for
every time step check necessary updates, or close the
job when ready.
- No drawing happens in jobs, that's for notifiers!
- Every job stores an owner pointer, and based on this owner
it will prevent multiple jobs to enter the stack.
Instead it will re-use a running job, signal it to stop
and allow caller to re-initialize it even.
- Check new wm_jobs.c for more explanation. Jobs API is still
under construction.
Fun: BLI_addtail(&wm->jobs, steve); :)
Put Node shader previews back using wmJobs
- Preview calculating is now fully threaded (1 thread still)
- Thanks to new event system + notifiers, you can see
previews update even while dragging sliders!
- Currently it only starts when you change a node setting.
Warning: the thread render shares Node data, so don't delete
nodes while it renders! This topic is on the todo to make safe.
Also:
- bug in region initialize (do_versions) showed channel list in
node editor wrong.
- flagged the channel list 'hidden' now, it was really in the
way! This is for later to work on anyway.
- recoded Render API callbacks so it gets handlers passed on,
no globals to use anymore, remember?
- previewrender code gets now so much nicer! Will remove a lot
of stuff from code soon.
