Keep file-system paths and PBD::Searchpath mostly separate.
This amends 58c2b0a848 libs/fst directly includes relevant
ardour C++ code, so lib/fst must not link against libardour.
The problem was that 58c2b0a848 introduced additional
dependencies on other libardour functions.
libardourcp and now libardour_midisurface are not control
surfaces, but helper libraries for those.
They need to be deployed to the library folder (shared between
ctrl surfaces) and not scanned as ctrl surfaces at runtime.
Having current_time as a public alias of the private last_when did not
add any clarity to the abstraction of last_time. A small step, but still
room for improvement.
Ignored strings were scanned to a buffer that potentially could
overflow. There might be hidden invariants that make actual overflow
impossible, but that seems like a fragile defense.
Instead, just *really* ignore them.
macOS has its own z-axis stacking (see Manager::set_transient_for) for
dialog and utility windows of a single application. There only case to
set a dedicated transient parent is to keep the child window on top of a
dialog.
Valid use-cases are e.g.
Plugin Preset Name entry on top of a PluginWindow
Export Format Settings on top of the Export Dialog
Alternatively one would need to patch gtk to handle
[NSView shouldDelayWindowOrderingForEvent] and explicitly reorder
siblings of a common parent window.
This fixes an issue that plugin windows cannot be re-stacked but were
previously always stacked in the order they were opened.
This fixes an issue with plugin state save/restore. Some
require excessive stack to do that (looking at you b.oops.lv2).
The main GUI thread has no stack limit, so this is only an issue
when calling state save/restore from background threads.
Writing partial messages will lead to undefined behavior.
This does not generally happen (LV2 forge prevents overflow
of the Atom buffer itself), however if the GUI is frozen messages
may accumulate in Ardour's Ringbuffer.
Processor::deactivate must not be called concurrently with
processing. e.g. Threading rules https://lv2plug.in/ns/lv2core
This fixes a potential crash when freezing tracks
