The set uses a custom sort-by-name comparator.
Previously it was possible to have an inconsistent set iterator.
std::set::find() did not find a given port while std::find() did.
This fixes using std::set::find() on the PortIndex set.
Temporal::most_recent_engine_sample_rate is used in performance-critical code so shouldn't be accessed via a 'get()' function. But (via the TEMPORAL_SAMPLE_RATE #define) it does get accessed outside of libtemporal and therefore needs to get exported.
We were using a given tempo or meter point as part of the metric used when
recomputing its position. In fact, the metric should be only use the
tempo/meter immediately preceding the given point.
It is more useful to get the actual TempoPoint than just the Tempo
that we discover.
Aside: it would be awesome to understand how to use boost::intrusive to get the
next tempo point directly from the tempo hook.
On M1, the cross-thread channel sets G_IO_PRI in addition to G_IO_IN
this breaks various assumptions in receivers, which test for ~G_IO_IN
as error condition.
We modify elements of the source object, not to mention the peakfiles on disk. This
was a regression introduced when switching from Lock to RWLock, caused by a failure
to recognize this as a case where a write lock was required.
The presence of scoped_array<> as a member of AudioSource (peak_cache) is suspicious
nevertheless, and we should establish that it serves a useful purpose.
Return from poll_for_request() when CrossThreadChannel is
closed/destroyed. -- see also f4166fb61d
This also cleans up poll API usage, and check for nonnegative
return value is added.
This is mainly relevant for Mixbus, which allows cyclic-connections
to record Master-out on a Track (which unconditionally has Mixbus send
and feeds master).
In Ardour it may also cause issues when creating loopback connections,
however latency is not usually updated with invalid graphs (old
process graph remains in use).
Otherwise it fixes a crash connecting Track 1 -> Track 2 -> Track 1.
This also optimizes Route::output_effectively_connected by caching
any prior lookup. This helps e.g. Track 1 -> Track 2 -> Master.
The connection "Track 2 -> Master" now only need to be looked up once.

Changes handle_cursor_right_press() in PluginSubviewState to pure virtual
function so that PluginSelect and PluginEdit can each have their own
version.
The cursor_left and cursor_right mackie control buttons will now move the
sends subview left and right like it does in the plugin subview. Previously,
if you had more than 8 sends (which is almost always the case for Mixbus),
then sends 9+ were unreachable on an 8 channel controller.
This is in preparation for a pure-virtual base class for
PluginInsert to expose `DropReferences` in the virtual base.
```
class PlugInsertBase : virtual public PBD::Destructible
class PluginInsert : public Processor, public PlugInsertBase
class Processor : public SessionObject
class SessionObject : public PBD::StatefulDestructible
```
