2017-08-12use a lock to set/get AutomationList automation statePaul Davis
It isn't 100% clear that we should use the list's data lock, but it seems quite likely that this is the correct design, because of the interlock between data being present and automation state

2017-08-07Work around a Windows crash (for now)Robin Gareus
The root-cause is likely PortAudio backend specific async port-registration, re-establish ports after session creation and after the first callback and it's apparently a race-condition: crash is not 100% reproducible. #10 0x00007ffb156df18a in msvcrt!abort () from C:\Windows\System32\msvcrt.dll #11 0x0000000012597832 in _wassert (_Message=_Message@entry=0x2eaf96f0 L"_port_handle", _File=0x2 <error: Cannot access memory at address 0x2>, _File@entry=0x346a1430 L"../libs/ardour/audio_port.cc", _Line=80) at ../../mingw-w64-crt/misc/wassert.c:54 #12 0x00000000125978e8 in _assert (_Message=0x1282f7e9 "_port_handle", _File=0x1282f7a0 "../libs/ardour/audio_port.cc", _Line=80) at ../../mingw-w64-crt/misc/wassert.c:30 #13 0x00000000120d1a51 in ARDOUR::AudioPort::get_audio_buffer (this=0x34a95a70, nframes=256) at ../libs/ardour/audio_port.cc:80 #14 0x00000000126724f9 in ARDOUR::AudioPort::get_buffer (this=<optimized out>, nframes=<optimized out>) at ../libs/ardour/ardour/audio_port.h:43 #15 0x0000000012435421 in ARDOUR::Session::ltc_tx_send_time_code_for_cycle (this=this@entry=0x37666310, start_frame=0, end_frame=end_frame@entry=256, target_speed=0, current_speed=0, nframes=nframes@entry=256) at ../libs/ardour/session_ltc.cc:180 #16 0x000000001245209f in ARDOUR::Session::no_roll (this=this@entry=0x37666310, nframes=256) at ../libs/ardour/session_process.cc:145 #17 0x0000000012453051 in ARDOUR::Session::fail_roll (this=this@entry=0x37666310, nframes=<optimized out>) at ../libs/ardour/session_process.cc:128 #18 0x0000000012459ebd in ARDOUR::Session::process_without_events (this=this@entry=0x37666310, nframes=nframes@entry=256) at ../libs/ardour/session_process.cc:897 #19 0x000000001245a462 in ARDOUR::Session::process_with_events (this=0x37666310, nframes=256) at ../libs/ardour/session_process.cc:425 #20 0x0000000012451bc5 in ARDOUR::Session::process (this=0x37666310, nframes=nframes@entry=256) at ../libs/ardour/session_process.cc:78 #21 0x00000000120e79fd in ARDOUR::AudioEngine::process_callback (this=0x23316e30, nframes=256) at ../libs/ardour/audioengine.cc:376 #22 0x00000000285390fe in ARDOUR::PortAudioBackend::blocking_process_main (this=this@entry=0x29e67750, interleaved_input_data=interleaved_input_data@entry=0x115e8790, interleaved_output_data=interleaved_output_data@entry=0x115e0050) at ../libs/backends/portaudio/portaudio_backend.cc:1962 #23 0x0000000028539b75 in ARDOUR::PortAudioBackend::process_callback (this=this@entry=0x29e67750, input=0x115e8790, output=0x115e0050, frame_count=<optimized out>, timeInfo=0x3d17fd70, statusFlags=statusFlags@entry=0) at ../libs/backends/portaudio/portaudio_backend.cc:775 #24 0x0000000028539c16 in ARDOUR::PortAudioBackend::portaudio_callback (input=<optimized out>, output=<optimized out>, frame_count=<optimized out>, time_info=<optimized out>, status_flags=0, user_data=0x29e67750) at ../libs/backends/portaudio/portaudio_backend.cc:721 #25 0x00000000632c528f in NonAdaptingProcess () from C:\Program Files\Mixbus32C-4\bin\libportaudio-2.dll #26 0x00000000632c73b2 in PaUtil_EndBufferProcessing () from C:\Program Files\Mixbus32C-4\bin\libportaudio-2.dll #27 0x00000000632d129c in ProcessingThreadProc () from C:\Program Files\Mixbus32C-4\bin\libportaudio-2.dll

2017-08-06Emit SelectionChange when VCA is removedRobin Gareus
chicken/egg: Stripable d'tor which calls remove_stripable_by_id() will only be called when the Stripable is destroyed. But as long as the GUI selection holds a shared-ptr reference to the Stripable, it won't be destroyed.

This fixes MIDI Input follows MIDI track selection (and maybe other issues) and hopefully breaks nothing else (most places subscribe to both Stripable::PropertyChanged and PresentationInfo::PropertyChanged).

2017-08-03Some more assert() debuggingRobin Gareus
2017-08-03Ignore cycle-start/end for unregistered portsRobin Gareus
Should fix a race during Session::destroy(), Port::PortDrop which unregisters ports with the backend, but the actual port instance will still exist. The engine does no longer have a session-pointer and only calls CycleStart(); CycleEnd() to clear port-buffers. Trying to clear and already unregistered Port will crash.
2017-08-03improve 1a288ddd, destroy IO after disconnecting from signals.Robin Gareus
This does not completely fix the race-condition. The GUI (e.g. connection-manager) may still hold a shared-ptr reference.
2017-08-03Fix crash when cleaning up w/o destroying sessionRobin Gareus
- Control-protocols may transmit data during cleanup (e.g. reset surface), and need the Audio-engine to do so. - destroying the ControlProtocolManager w/o the Session calling ::drop_protocols(), lead to a double free.

2017-08-01Fix LTC encoder removalRobin Gareus
Fixed a crash if an x-run or graph-reorder happens after the LTC encoder has been destroyed (possible at session-close or after disabling the encoder). This also fixes duplicate callbacks in case the encoder was re-enabled times in an active session.

... in .ttl file rather than by extension_data() in code. That's more in the spirit of LV2.

This is currently done by an extension data similarly to LV2_INLINEDISPLAY__interface.

2017-07-26Fix initial sync to LTC with small buffersizesRobin Gareus
Ardour follow_slave() does nothing (not even seek) if the slave is not locked. The LTC-slave assumes it's locked if LTC is stable for 5 continuous process-calls. If the difference of Ardour's transport-position to the LTC-timecode is large (> 2sec), the slave reset itself (assuming drift, seek don't vari- speed). A LTC-slave does reset does reset the locked counter. Hence: If initially Ardour's transport differs > 2 sec and the buffersize is small (many process-callbacks), the slave kept resetting itself never informing Ardour that it locked to the external TC, and Ardour never issued a seek.
