This allows to indicate that a control should by default be displayed
inline in the mixer-strip.
Previously that was hard-coded for and enabled for send-level
controls only.
It's long been a guideline (and IIRC a Weff-c++ warning) that either all, or
none, of the copy methods should be defined, but this became a standard warning
in GCC9. Presumably to account for a later language change though I'm not sure
which.
I don't remember why the ChanMapping copy constructor can't just be a simple
copy (it's just a map of POD), but figure it's safer to just copy what that
does.
103ef2ba08 introduced an API to write raw data (const void*)
to a child process, along with the previous API to
write (std::string const&)
VideoMonitor uses write_to_stdin("fixed text"), and g++
interprets this to use the (const void*) API instead
of the std::string, which breaks communication.
It's a well established convention that pan y-axis automation,
or vertical uses (top) +1 for left.
This special cases rotary knobs (and horizontal sliders) to retain
a clockwise movement (or movement to the right) for panning to the
right.
There are still over a hundred left, but this addresses many already.
In particular @param references to undocumented parameters.
Most notably in audio_backend.h
This works around for compilers with non-static-data-member
initialization.
spinlock_t is-a struct { lockType _; } and BOOST_DETAIL_SPINLOCK_INIT
initializes the first member of the struct.
All defines of BOOST_DETAIL_SPINLOCK_INIT include c-style curly braces
to initialize the struct's data member.
However, modern C++ compiler interpret the braces differently resulting
in copy constriction of the initializer.
Depending on implementation, d8ae3fd may only construct the spinlock
once to `sl_init`. Later it is only copy-constructed and that leads to
compile and/or runtmime errors.
e.g. gcc-8.3 fails to compile
error: use of deleted function ‘boost::detail::spinlock::spinlock(const boost::detail::spinlock&)’
To facilitate a central registry with weak/shared pointer lookup,
enable_shared_from_this<ARDOUR::AutomationControl>
was migrated to
enable_shared_from_this<PBD::Controllable>
The main (and only) user is generic-midi surface's state interface :(
