smf_delete() does not handle NULL, and segfaults instead.
This only crashes with optimized builds.
libsmf will call g_critical() earlier and in that case debug-builds
call UI::handle_fatal() and ask the user to "click to exit".
This fixes VST parameter prop.flags (toggle, integer-step).
VestigeMaxLabelLen is used in various places in libardour, most notably
with effGetParamName.
CoreMIDI ports are dynamic. When dis/connecting a device CoreAudio's
AudioHardware-PropertyListener triggers a callback which can
add/remove ports.
This can not happen concurrently with processing, but it may happen
concurrently with a user creating tracks using Ardour's UI
and/or session-load/setup.
Empirically this decreases gc-spike duration (worst-case) by a factor of
two and speeds up the average gc-run by a factor of over 4 (depending
on the amount of memory used by the plugin).
Add custom API to prevent Lua Objects from being garbage collected.
This is intended to for Ardour LuaBridge bindings (~1MB Objects:
tables, functions and userdata).
The bindings are persistent and the gc can skip them in mark & sweep
phases. This is a significant performance improvement for garbage
collection.
Note. The next version of Lua (5.4) will come with a generational-gc
rather than an incremental, so extending the API at this point in time
is acceptable.
It may happen that WaveView requests a range that is larger than
the data on disk.
If start > _length, cnt becomes negative and the function will throw
or segfault.
Initialize LADSPA tags.
Explicitly define behavior of tags provided by plugin, factory, or user.
Store the plugin name in the tag-file, for easier user-submissions and bulk editing.
