This correctly matches reserved words when looking
up C++ documentation, but prints the exposed binding.
e.g. ARDOUR::PluginInsert::type -> ARDOUR.PluginInsert._type

The mixer gain-entry selects all when the entry is focused
(see ArdourWidgets::FocusEntry). Due to the selection there is
no visible cursor, and it was not obvious that the entry
has focus. Also moving the mouse outside of the strip drops focus
without any indication.
"While 'atomic' has a volatile qualifier, this is a historical
artifact and the pointer passed to it should not be volatile."
Furthermore "It is very important that all accesses to a
particular integer or pointer be performed using only this API"
(from https://developer.gnome.org/glib/2.68/glib-Atomic-Operations.html)
Hence initialization of atomic variables is changed to also use
this API, instead of directly initializing the value.
This also fixes a few cases where atomic variables were
accessed directly.

This combines SessionEvent per playlist. Now per change
there are "only" two SessionEvent::Overwrite events
queued per playlist in the GUI thread for later processing
the Butler.
These are triggered by Playlist::ContentsChanged()
and Playlist::LayeringChanged(), both of which trigger
DiskIOProcessor::playlist_modified.
(Previously there used to be two per region)
Playlist::ContentsChanged() is implicit.
Region::send_change()
-> Playlist::region_changed ()
-> Playlist::notify_contents_changed ()
-> Playlist::ContentsChanged () /* EMIT SIGNAL*/
This cuts the number of signals in half and also
allows to freeze/thaw the playlist to collect the
signals for each playlist into a single signal.
With a large session:
Editor::insert_time()
-> Playlist::shift()
-> 4000+ regions are modified
-> 4k calls to Region::send_change()
-> --"-- Playlist::region_changed ()
-> --"-- Playlist::region_bounds_changed ()
-> --"-- Playlist::notify_contents_changed ()
-> --"-- ContentsChanged () /* EMIT SIGNAL */
-> --"-- DiskReader::playlist_modified ()
-> 4k Session::request_overwrite_buffer events are queued
The butler thread processes them all in the background, but
this also enqueues 4k+ events to the GUI event pool since the
GUI subscribed to Playlist::ContentsChanged ().
However the GUI is inside Editor::insert_time() and cannot handle
events. So they keep accumulating, and eventually hits
"POOL OUT OF MEMORY - RECOMPILE WITH LARGER SIZE!"
-=-
This fixes the issue by collecting blocking ::notify_contents_changed
until all region_changed() events are processed, and a single call
to Playlist::flush_notifications() notifies the UI and disk-reader.
This works around JACK not allowing to directly access physical
input buffers by creating an explicit connection.
Ardour access input-buffers directly without connection
for input meters and AFL. This work in general since data
on those ports are always read unconditionally at the start of
each process cycle.
jack_port_get_buffer (jack_port_by_name (c, "system:capture_1"), n);
However with jack this fails if the given port is not connected.
Due to an internal jack optimization collecting input data is
skipped for ports that have no connections.
This fixes the following edge-case:
1. Place a custom transient marker.
2. Use Rhythm Ferret to analyze region.
3. Delete custom marker from (1) while rhythm-ferret
dialog is still open, and analyzed onset markers are visible.
"T: " prefix isn't very useful. in music-notation the note
symbol is established: ♩ = <bpm> or ♪ = <bpm>.
This fixes an issue on Windows, where those note symbols are
not available in the default unicode font. There "1/4" is used
which adds two extra monospace chars leading to cropped text.
PortAudio uses what it calls 'default suggested latencies' but in callback streaming mode, they can result in wildly inaccurate buffer sizing (e.g. the user requests a buffer size of 128 but PortAudio actually instructs ASIO to use a much bigger size).
What we do now is to improve PortAudio's suggested latency calculation by basing it on the actual buffer size requested by the user.
By default Apple uses a private TMP folder. While mktemp
returns "/tmp/xxx" the canonical path is "/private/tmp/xxx".
This lead to issues when tmp-prefix is removed when building
the session-archive.
