process_index should not be compared/combined with expected_end_sample, since
the former is a process-cycle count and the latter is a timeline position.
* first the region is scanned for bpm and one-shot status
* then we handle properties that should be applied from a drag&drop
* then we handle the existing arrangement-style slot properties that should persist
This should not be needed, however Editor::idle_remove_tracks()
has the same priority as Editor::redisplay_track_views() and this
might save us another redisplay call.
There is probably a good reason why _vca.reset() is called
immediately, and 6dc66ea78f is a better solution to the issue
This reverts commit 83719fba1a.
This addresses the issue described in 83719fba1a.
First process all queued self_delete() requests before scheduling
Editor::redisplay_track_views() which uses PRIORITY_DEFAULT.
Session::remove_routes() first calls IO::disconnect()
before eventually calling route->drop_references().
RouteTimeAxisView::io_changed() is called while the route still
exists and requests a redraw which in turn emits
_stripable->gui_changed ("track_height").
Since the RTAV is deleted later during an idle-callback, there
was another redraw performed just before the RTAV is actually deleted.
VCATimeAxisView::self_delete () resets _vca and queues delete_when_idle.
From now on STAV::strippable () will return 0.
Editor::idle_remove_tracks() returns, and before the VCATimeAxisView
is destroyed. Editor::redisplay_track_views() may be called.
The VCATimeAxisView still exists at this point and is in
Editor::track_views, but has no valid stripable.
This causes a crash in TrackViewStripableSorter which depends
on STAV::stripable();
THe length of a Source(File) is always measured from its start. In this sense,
the length is like a position on the timeline, which is a duration with an
implicit origin, or a Region start, also a duration with an implicit origin (in
that case the start of the Source). There is no good reason for using
a timecnt_t for this value, because the position component of a timecnt_t
(the origin for the duration) is implicit and always zero. So we make
this property into a timepos_t, and include a number of asserts() to check
for common possible coding errors related to the time domain
The length needs to use consistent time domains for duration and position,
and total_capture is a sample count. The "real" length of a whole
file region is the length of its source, so just defer to that.
Session::process_audition calls Graph::swap_process_chain()
to handle any pending graph changes (notably route removal
depends the graph to switch chains to drop references).
However this must not change the Graph::_trigger_queue
(which is refilled when processing resumes).
Previously routes were added to the trigger_queue, leading to
an inconsistent Graph state. When the terminal-count was reached
the trigger-queue was not empty. Process threads ran after processing
already completed and or concurrently with processing.
A common result of that was:
delayline.cc:70: virtual void ARDOUR::DelayLine::run(ARDOUR::BufferSet&, ARDOUR::samplepos_t, ARDOUR::samplepos_t, double, ARDOUR::pframes_t, bool): Assertion `lm.locked ()' failed.
This is required to be able to include
"audiographer/sndfile/sndfile_writer.h" in more than
one source file. which would otherwise lead to
duplicate symbol: AudioGrapher::SndfileHandle::..
In session file formats earlier than 7000, region position and length
are stored in distinct XML node properties. For 7000 or later, both
position and length are part of the "length" member. Fix reloading
this by noting session file format and loading position and length
more explicitly
