Most calls to new_audio_route() used save = false, only directly
creating busses saved the session. Probably for historical reasons.

loop for loop play
|
|
Since we now (correctly) do not locate for loop changes, this member
is unnecessary
|
|
|
|
Also remove redundant double call to Track::set_block_size(). This dates back to 2010
when there used be an additional traversal of the Diskstream RCU-managed list, before
they became owned by Tracks
|

This is done in order to set the TransportGenerator flag

Port and connection changes always imply a latency_callback from
the engine. Worst I/O latency is updated directly in
Session::update_latency() which is called from
AudioEngine::latency_callback.
Explicit subscriptions to route->output()->changed() is not needed
to update the worst I/O latency.
Only set_block_size() needs to to update the I/O latency when
the buffer-size changes.

Auto-connect is handled in a background thread, so newly created
tracks are not immediately connected.
This causes a race-condition when fan-out directly disconnects
and re-connects ports after track/bus creation.

When we create a new session and are using a template from an old version of
Ardour, we should not issue the VersionMismatch dialog and not make a copy of
the session file for the old version.
We need to extend the signature of Session::load_state() to tell it if we are
creating a session from a template. Session::_is_new cannot be used for it
because it has a the semantics if to auto connect the the master bus.

identifies it as unnamed
This way they will not be asked again if they reload and then quit the session
|
|
Note that this is done at the GUI level, might need to double check if there are
other paths into a "save" that should be covered. Control surfaces use the action, but
Lua comes to mind

Leave debug output in place for now to get some numbers from any testers

Substantive comments associated with code in Session::plan_master_strategy.
Known not to work for reverse TC. Also, the JACK related code has not yet been tested

This is also needed when exporting.

This is in preparation for GUI sensitivity of Loop and Punch actions.
|
|
This also prevents switching between punch-in/out record
and looping without transport-stop.

management and motion state (partially) into TFSM

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.

This fixes a crash: missing playlist due to missing .mid,
and retains regions for missing MIDI files.
As opposed to missing Audio, we cannot use a SilentFileSource,
because MIDI files are destructive.
This also adds an API to query missing files that have been replaced
with silence to report them to the user.

This is in preparation for saving state while the session is
record-arm'ed. Most notably config changes and undo/redo.
In case both normal and pending save happens, pending must be
last and is required to recover from crashes during recording.

set_session_extents had a bug; it wasn't calling locations->add()
on the newly created location.
The correct implementation was in set_session_range_location,
but this was only called from one place.
This function was removed, and set_session_extents will be used in its place.
set_session_extents will create a session location if one no longer exists,
so there is no need for set_session_range_location.

This differs from ::locate_pending() by covering either phase of a locate - declick or refill
|
|
|
|
Because of the addition of LocateTransportDisposition, this call was unconditionally forcing a roll during startup
|
|
|
|
"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
|
|
|
|
|
|
Session::TransportStateChanged notifies about transport stop before the stop is complete (i.e. at the start of the declick).
Various other objects (notably control surfaces) connect to this signal and use it to modify their displayed state.
We need a method that can tell them we are stopped (or stopping) even though we are not "fully" stopped yet. This is
that method
|
|
up to the nearest buffer size
|
|
Note: there is no global state for "the" transport master, since we have several at all times now
|
|
This might fix a "SessionHandleRef exists across session deletion",
when the shared_ptr was be pushed onto a x-thread pool, and not
invalidated in time before the session was closed.
|
|
destroy_sources () is only called from Session::remove_last_capture ().
The list of sources to be destroyed is the local scope of that method
and will hold a reference to the object.
copy-construct the list and removing elements one by one from the
copy is only unnecessary overhead.

Removed (mistakenly) during work on transportFSM
