It is not needed in the relative case and causes issues when taking
sessions between platforms.
On windows, the default path would be "\export". When that is used
on linux the resulting fullpath would end up as
/your/session/path/\export
which is then not found on the file system.
This change is consistent with how relative paths are normally written and
does cure the default path when moved across platforms.
It does not solve the larger issue of mixed directory separators.
A relative path of "export\myMixV1" will still fail when moving between
platforms.
Previously the following were treated as equal
"MIDI_foo" == "MIDI bar"
So std::map<> PortManager::_ports and PortEngineSharedImpl:_ports
could only have either. This resulted in missing ports
and missing calls to existing ports in cycle_start().
This mainly affected MIDI tracks with imported files, since there
is "MIDI Clock in", and imported files result in tracks
"MIDI_file-name".
This issue was introduced in 6.6-200-g60ff3ef764
We do need to know that a reversal is intended before we do a locate, but we should
not enter Reversing before the declick is finished. So instead, we add a new
member, _reverse_after_declick to keep track, and enter Reversing just before
we start the locate
select(2) can only handle file descriptors up to 1024, and there are fairly easy to reproduce
cases where the file descriptor used here is larger than that.
Portmanager uses "ports" as local variable in various places
(usually vector<string>). While the compiler is fine with that,
it is confusing when debugging or reading code.
Since Ardour 6, a transport speed of 200% will also double
DSP load. Under the hood Ardour rolls twice the distance and
the output is downsampled.
Vari-speed > +/-200% will likely cause dropouts with many
sessions on most systems, users should explicitly select it.
The TransportFSM is now responsible for deciding what to do at all transport state transitions. The Session (via the TransportAPI) merely
provides mechanism (locate, start, stop, set_speed). Default and most recent speed requests are managed by the TransportFSM too
This fixes another deadlock calling send_change with the
Playlist's RegionWriteLock held.
In this case due to "MIDI region copies are independent"
when duplicating MIDI regions.
```
ARDOUR::Region::send_change ()
PBD::Stateful::apply_changes ()
ARDOUR::RegionFactory::create ()
ARDOUR::RegionFactory::create ()
ARDOUR::MidiRegion::clone ()
ARDOUR::RegionFactory::create ()
ARDOUR::Playlist::duplicate ()
```
