The column labels are drawn in an angle towards the edge where the row labels
are. Therefore, if the column labels are much longer than the row labels it can
happen that they go beyond the left edge. In that case we have to add an extra
width to the row labels.
When a PluginInsert is created it does not have an owner right away. That's why
a we need to set the sidechains name once the owner is known, in order to
include owner's name into the name.
Furthermore we need to follow renames of the owner.
Some plugins return 0 from effGetVstVersion and are hence not detected
as instruments. e.g. VeeSeeVSTRack (VCV). This may also explain why MIDI
port of some other VSTs are not exposed.
Most VST2.4 return 2400, so checking [effGetVstVersion] >=2 (and not 2000)
was incorrect to begin with.
VCVRack VST currently exposes 9999 automatable-control parmaters.
This slows down various GUI dropdown lists and dialogs.
(even worse: those parameters are not mapped to anything by default).
This change allows to limit automatable parameters to a reasonable number,
without loosing state of already automated parameters in existing sessions.
This fixes an issue with Mixbus. If the default "Create Audio Tracks.."
template/script is not available. Nothing is selected.
Selecting a type/template is required to update various other dialog
fields. eg. "Name" field.
Previously: Create VCA. OK+Close. Re-open dialog. Now the
implicit default was "Audio Track" but the Name-field still showed "VCA".
This is required by 7d8b93ad for showing error when actively recording.
It also prevents other UIs (OSC, Lua,..) to change re-configuring
sidechain ports/plugins while recording.
- _session cannot be NULL while the dialog is visible.
This removes extra `if (_session)` tests.
- Operations now no longer fail silently, but show error messages.
PluginPinWidgets initially receive their Session pointer by
PluginPinDialog::set_session(). When a RouteProcessorChange occurs all
PluginPinWidgets are recreated. Those newly created instances need a pointer to
the session.
A "fall through" comment is most portable way to indicate
"no break, fallthru" cases.
* __attribute__ ((fallthrough)) // is not portable
* [[fallthrough]]; // is C++17
lili93's session (#ardour) triggered this w/jackd 512fpp:
Drag/Drop copy a latent plugin from one track to another while rolling.
The GUI-thread as well as the auto-connect thread concurrently call
jack_recompute_total_latencies(). The auto-connect thread holds
a process lock while doing so. The GUI does not use any mutexes.
This randomly deadlocks in libjack.

This is more of a workaround than a fix. Simply by forcing the
URI to be sortable (VST-user presets are sorted at the end).
This eventually needs a deeper cleanup and API consolidation
PluginInfo::get_presets(bool) returns an ordered std::vector.
However this API is only used in a few cases where the plugin is
not instantiated. PluginInfo::get_presets(bool).
The problem is Plugin::get_presets(). The method returns
information that was previously cached by Plugin::find_presets() in
std::map<URI, ...>
Ardour's VST MIDI buffer API does not yet implement offsets and limits.
When a cycle is split, the same midi-buffer is used for all sub-divisions
leading to duplicate, offset, events.
