With 4MB RAM and 1.5MB locked base memory (C++ bindings),
TLSF has a better worst-case performance (-20% std-dev
execution time compared to realloc-pool).
Even though on average Realloc-Pool performs better (-9%
average time, compared to TLSF).

Since Lua function arguments are not typed, there is no
explicit "const", and a function can always modify the parameter.
When passing `ChanMapping const&` as argument, the object is
copy constructed. In this specific case the std::map<> members
of ChanMapping allocate memory.
Passing a pointer to the object works around this issue.
LuaBridge later dereferences the object as needed when calling
c++ methods, and copy-construction would only happen later.

PluginInsert (and a few other places) iterate over channel
mappings using a const iterator. However mappings()
allocated memory since it was copied

Expose zita-convolver bindings, to allow for
custom NxM convolution matrices, and dedicated FIR processors.
|
|
|
|
This will come in handy for FIR, or short samples in combination
with a Lua convolution processor.

This add support for Lua bindings for static member
functions in weak/share ptr class bindings.

undo may restore locations, which may trigger a state-save.
This can result in a deadlock:
Location::set_state () -> Locations::get_state()
both acquire a the same lock:

This is in preparation for saving state while the session is
record-arm'ed. Most notably config changes and undo/redo.
In case both normal and pending save happens, pending must be
last and is required to recover from crashes during recording.

This builds on top of 51d2bb:
* v6 routes templates/states have a version per <Route>
* older route-states are assumed to be from ardour-5
Stateful::loading_state_version 3002,
unless specified otherwise
|
|
Currently using Ardour-5 route templates (state version "3002")
with Ardour6 fails. As opposed to session-templates, Route
templates were not versioned.
This ensures future compatibility (and may allow to interpret
unversioned templates as "3002")

Loop recording creates a single long source, regions have to be
"split" from this source, using "start" as offset.
Since MIDI uses absolute timestamps, offsetting this by accumulating
buffer_position += (*ci)->samples;
like Track::use_captured_audio_sources() does, is not correct.
Furthermore, record_enabled() may be off when stopping recording,
MIDI needs to be flushed regardless.
|

DiskWriter::transport_looped() is called from the session
when engine loops. This does not take local disk-reader run()
latency offset into account.
finish_capture() needs to be postponed until the disk-writer
itself reaches the loop-position. This is achieved by
postponing loop() and calling it once loop-length of samples
has been captured.
This works because engaging loop always seeks to the loop-position
and first loop resets _capture_captured.

This also removes a Mixbus special case, explicit ->mixbus() tests
are no longer required.

Ardour 5.x slave check was incorrectly ported to A6's TMM:
In Ardour 5 the comparison tested for *not* MTC:
```
if (!dynamic_cast<MTC_Slave*>(_slave)) { ..send MMC.. }
```
Other MMC messages (Record, Locate) are sent unconditionally.
|
|
This fixes an issue that after changing backends (::set_backend),
the session-transport was in inconsistent state. If it was rolling,
it continued to roll with "stop" being unavailable.

set_session_extents had a bug; it wasn't calling locations->add()
on the newly created location.
The correct implementation was in set_session_range_location,
but this was only called from one place.
This function was removed, and set_session_extents will be used in its place.
set_session_extents will create a session location if one no longer exists,
so there is no need for set_session_range_location.

* Windows: delete waf installed .dll.a files
* Windows: override waf's conf.env.LIBDIR = conf.env.BINDIR
with explicit --libdir
* Windows: fix asm (`x86_64-w64-mingw32-as` -D flag is for
debug messages, -D defines are not available)
* Mac: override waf adding -install_name (and
-Wl,-compatibility_version -Wl,-current_version)
by moving -dynamiclib from linkflags to ldflags
* Mac: Allow libs with compat version number suffix
(not needed anymore, but may help in the future)

Previously this was inherited via PBD.
On MacOS/X, this adds
"-undefined dynamic_lookup -flat_namespace"
and various "-framework .." options to linkflags
Without this flag, .dylibs fail to link usually because
of missing `-lintl` (Undefined symbols: "_libintl_dgettext")
On other systems this is a NO-OP:
CFLAGS_OSX, CXXFLAGS_OSX and LINKFLAGS_OSX
are only set on the darwin platform.
