Paul Davis b35518e212 switch from boost::{shared,weak}_ptr to std::{shared,weak}_ptr 
This is mostly a simple lexical search+replace but the absence of operator< for
std::weak_ptr<T> leads to some complications, particularly with Evoral::Sequence
and ExportPortChannel.

Only dump SessionEvent pool in debug builds 
This ensures that the user will see a "POOL OUT OF MEMORY" message.
In rare case dumping the pool can segfault when printing the Event,
The pool is zero initialized and only ever contains events, so
in theory it is safe to print them..

Merge Overwrite request for the track 
Previously events with different reasons where treated as two
separate events. Processing an Overwrite request causes
post-transport-work to set.

Since ::non_realtime_work_pending() is true, process_event()
is not called, and no further immediate events are evaluated in
the same cycle.

So Overwrite requests were repeated over multiple cycles.

Ensure that immediate events are not accidentally replaced 
All Immediate events have the same action samples, while other
parameters differ. Those events must not be removed by a
call to _remove_event(), particularly not SessionEvent::Overwrite

Remove unused #include<> (2/2) 
PBD::stacktrace() is not used nor needed by default.
It should be used sparingly.

Paul Davis cc543280d9 We were 2 more debug "bits" away from overflow, so recast PBD::DEBUG mechanism away from a 64bit integer and toward std::bitset.

Robin Gareus fe85575a12 fix “no per-thread pool” abort 
For some backends the process thread can change (e.g.
switch coreaudio headphone + internal speakers)

If there are existing x-thread event calls this can lead to
the following situation:

1) SessionEvent::operator new
2) audioengine process thread change
3) SessionEvent::operator delete  -> crash, wrong thread

SessionEvent::operator delete can safely push the event back to
the pool for later cleanup..

Paul Davis 78e245d0b5 do not attempt to call an empty/null boost functor in clear_events() 2015-02-05 18:03:40 -05:00
Paul Davis 6790f8342a expand SessionEvent API to allow ::clear_events() to work correctly. 
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.
 2015-02-05 16:32:21 -05:00
Paul Davis 76d42ab644 change SessionEvent::Immediate to -1, and ensure that clear_events() uses it 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.

David Robillard 6fa6514cfd Remove over 500 unnecessary includes (including 54 of session.h). 
It's slightly possible that this causes trivial build failures on different
configurations, but otherwise shouldn't cause any problems (i.e. no actual
changes other than include/naming/namespace stuff).  I deliberately avoided
removing libardour-config.h since this can mysteriously break things, though a
few of those do seem to be unnecessary.

This commit only targets includes of ardour/*.h.  There is also a very large
number of unnecessary includes of stuff in gtk2_ardour; tackling that should
also give a big improvement in build time when things are modified.

Paul Davis 8dab33c609 Route::set_meter_point() is now conceptually RT safe, although it still takes a write lock on the processor list. this allows it to be called when setting rec-enable status on a route. not thoroughly tested, and still incomplete - single route rec-enables should probably use this pathway, and there is still no cross-thread cleanup from an RT route op request
