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.
2020-03-29Set thread-names (libs)Robin Gareus
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

2020-02-19remove "destination_sample" from API for Session::set_transport_speed()Paul Davis
This was a leftover from changes made for Tracks Live, related to the concept of an auto-return preference. We don't use this anywhere in Ardour or Mixbus, and the concept should eventually be removed entirely.
2020-01-18Session::request_locate() takes a tri-valued second argument for ↵Paul Davis
"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

2019-11-14Fix cycle-end position when not rollingRobin Gareus
When stopped start_sample == end_sample. This fixes accidental automation lookup, as well as plugin time/position information.

2019-03-18NO-OP: Use API to set/test state-of-the-stateRobin Gareus
2019-03-14Unused skeleton of the transport state-machineRobin Gareus
Simple test/example code. Eventually this is to replace Session::process_event() and Session::realtime_*() methods are to become transition actions.

2019-02-26reorder call to ::track_transport_master() so that delta is computed correctlyPaul Davis
2019-02-06Fix rolling backwardsRobin Gareus
When speed is -1, start_sample >= end_sample and _transport_sample needs to be decremented. Session::process_with_events() did this correctly, this change makes Session::process_without_events() behave identically.
