2020-04-12Fix loop range changes while playing - #8001Robin Gareus
Since ead883302fe800ae, it is no longer possible to use a null pointer SessionEvent::track as flag to indicate overriding all buffers.
2020-03-28Don't use shared-pointers in cross thread event structsRobin Gareus
This fixes a deadlock when closing the session. Session::destroy() takes the engine-lock while removing unhandled session-events. In [1], the event-queue held a last reference to a Track, and releasing that object triggered events (here ~IO) that required the lock. --- [1] #2 0x0041743a in Glib::Threads::Mutex::Lock::Lock at /home/ardour/linux-armhf/stack/include/glibmm-2.4/glibmm/threads.h:643 #3 0xb67433ba in ARDOUR::IO::~IO at ../libs/ardour/io.cc:105 #4 0xb6743612 in ARDOUR::IO::~IO at ../libs/ardour/io.cc:111 #5 0xb6758e66 in boost::checked_delete<ARDOUR::IO> at /home/ardour/linux-armhf/stack/include/boost/core/checked_delete.hpp:34 #6 0xb675912c in boost::detail::sp_counted_impl_p<ARDOUR::IO>::dispose at /home/ardour/linux-armhf/stack/include/boost/smart_ptr/detail/sp_counted_impl.hpp:92 #7 0x004178d8 in boost::detail::sp_counted_base::release at /home/ardour/linux-armhf/stack/include/boost/smart_ptr/detail/sp_counted_base_sync.hpp:129 #8 0x00417986 in boost::detail::shared_count::~shared_count at /home/ardour/linux-armhf/stack/include/boost/smart_ptr/detail/shared_count.hpp:426 #9 0xb662343a in boost::shared_ptr<ARDOUR::IO>::~shared_ptr at /home/ardour/linux-armhf/stack/include/boost/smart_ptr/shared_ptr.hpp:341 #10 0xb6a4af7a in ARDOUR::Route::~Route at ../libs/ardour/route.cc:282 #11 0xb6b9404c in ARDOUR::Track::~Track at ../libs/ardour/track.cc:71 #12 0xb697164a in ARDOUR::MidiTrack::~MidiTrack at ../libs/ardour/midi_track.cc:94 #13 0xb697177a in ARDOUR::MidiTrack::~MidiTrack at ../libs/ardour/midi_track.cc:96 #14 0xb6ac525a in boost::checked_delete<ARDOUR::MidiTrack> at /home/ardour/linux-armhf/stack/include/boost/core/checked_delete.hpp:34 #15 0xb6acde00 in boost::detail::sp_counted_impl_p<ARDOUR::MidiTrack>::dispose at /home/ardour/linux-armhf/stack/include/boost/smart_ptr/detail/sp_counted_impl.hpp:92 #16 0x004178d8 in boost::detail::sp_counted_base::release at /home/ardour/linux-armhf/stack/include/boost/smart_ptr/detail/sp_counted_base_sync.hpp:129 #17 0x00417986 in boost::detail::shared_count::~shared_count at /home/ardour/linux-armhf/stack/include/boost/smart_ptr/detail/shared_count.hpp:426 #18 0xb664dca6 in boost::shared_ptr<ARDOUR::Track>::~shared_ptr at /home/ardour/linux-armhf/stack/include/boost/smart_ptr/shared_ptr.hpp:341 #19 0xb6aaf67e in ARDOUR::SessionEvent::~SessionEvent at ../libs/ardour/ardour/session_event.h:42 #20 0xb6a91a88 in ARDOUR::Session::destroy at ../libs/ardour/session.cc:753 #21 0xb6a8fb20 in ARDOUR::Session::~Session at ../libs/ardour/session.cc:460 #22 0xb6a9075e in ARDOUR::Session::~Session at ../libs/ardour/session.cc:46

"roll-after-locate" This allows callers to defer logic about auto-play/current rolling state and more to TransportFSM where it can be cnentralized and is less ambiguous
2019-12-10revert to single buffer for disk playback, and 5.x-style overwritePaul Davis

The flags were set, but not used. They also won't be needed anymore.

This API was not used, also superseded by record w/preroll.

2017-09-16Namespace PBD::RingBufferRobin Gareus
class RingBuffer<> is a very generic name and should not pollute the global namespace.
2017-07-04Fix session-event queue (multiple writer, single reader)Robin Gareus
The reading is done in rt-process thread, but multiple UIs (surfaces, GUI) can produce events to be queued.
2017-01-18Implement record with prerollRobin Gareus
2016-05-31universal change in the design of the way Route/Track controls are designed ↵Paul Davis
and used. The controls now own their own state, rather than proxy for state in their owners. Massive changes all over the code to accomodate this. Many things are not finished. Consider this a backup safety commit

2015-02-05expand SessionEvent API to allow ::clear_events() to work correctly.Paul Davis
clear_events() must run in realtime context, which is likely to be asynchronous with respect to the thread that calls it. So allow caller to pass in a functor that will be executed (also in realtime context) after the clear is done. Additionally, allow for a cross-thread callback to the event loop/thread which initiated/allocated the clear event request so that it can flush its own pending loop. This part probably isn't necessary but doesn't hurt and is a useful model. The event would be placed back in the free list at the next event allocation by the calling thread anyway.
2014-12-21change SessionEvent::Immediate to -1, and ensure that clear_events() uses it ↵Paul Davis
rather than a hard-coded value This fixes a design error of using zero as the flag for an "Immediate" event's action frame. Zero is a perfectly legitimate action frame for an event (e.g. a Skip event), and using zero was causing skip events with action-frame == 0 to be treated as immediate, not scheduled.

2012-06-22introduce the idea of a "default transport speed", used whenever ↵Paul Davis
Session::start_transport() is called. Only the shuttle controller alters it, and even that only alters it in wheel mode, which means that stopping the transport does not rever the default speed back to zero.
