This would crash (throw) if ardour was started with an invalid backend
(alsa with no devices avaliable) and then changec to an alredy running
jack. The invalid backend at the start would leave the buffer
size combo empty and switching to the running jack backend did not populate
buffer size list.
We can't use Lua to construct a PBD::SystemExec Obejct. Lifetime of the
object is bound to the Lua interpreter or local function scope.
Destroying the C++ object terminates the process.
Additionally to adding a dedicated method, we also override the existing
os.execute Lua libary method with a rt-save (vfork, close filedescriptors)
wrapper.
Changing the track-type to add changes the name which marked the
name-entry as "edited by user", even though it was Ardour itself
which changed the name.
Issue #6280 states that when selecting ranges using SnapToRegionBoundary it's
not possible to select regions with first_frame() == 0. This is because
Playlist::find_next_region() does not consider region boundaries == pos but
only > pos. Thus it never considers pos == 0 to be a region boundary.
This solution tries to be as little invasive as possible without changing the
semantics of PlayList::find_next_region(). Therefore position 0 is added to the
region boundary cache if there's a region starting at position 0 in any track.
Editor::redisplay_tempo() is called early on, before
Editor::set_timecode_ruler_scale() and Editor::compute_bbt_ruler_scale ()
are called. That is a bug which needs fixing (initial tempo+grid display)
. Still, uninitialized vars are not good.
Setting a tempo to 'Continue' via right click puts it in a permanent state
of continuing the previous section's end tempo (basically what
'Lock Continue' should have been). This can be disabled (unlocked) by
selecting 'Don't Continue'.
Remove the previous temporary 'Continue' function.
Reorganise menu to separate position lock style from more commonly
used functions.
It was assumed that the drag takes place within an area of musical time.
This is not true for the space before any non-initial
meter-locked tempo.
In the case of the initial tempo, there is no previous section
to perform an end-drag on.
If we've clicked on a tempo bar before the initial tempo,
don't allow anything to happen.
If it was just a click, ensure the tempo curve colour is restored.
Should provide better performance as we now only listen for changes in the
selected regions. Testing every changed region to see if its in
the selection was not working very well under some circumstances.
Length clock uses region relative time converter with offset to display
correct value over tempo changes.
Fix note length setting by using source time converter on a sample duration
based on a session-relative offset.
If the "Sorry I cannot do that" dialog is displayed from
FloatingTextEntry::use_text(), the entry is still visible and accepts
[focus] events. Also the dialog returns focus and multiple
idle_delete_self() will be called for an Entry that's already being
deleted.
Issue #7429 reports that that clicking a route of an already selected group
does not update the editor mixer strip selection. To fix this we call
Editor::set_selected_mixer_strip() at the end of
RouteTimeAxisView::selection_click();
The overhead of maybe calling it twice should be toleratable, as
::set_selected_mixer_strip() checks, if the route is already the current mixer
strip route before setting it.
* If the use-time-rulers-to-zoom option is enabled, -all- cursor drags can zoom.
* Behavior has been tweaked so it is easy to scroll without zooming, if you want to.
Depend on Changed() signals alone, which are usually much less frequent
than rapid-timer events.
As side-effect we now need to make the widgets insensitive when
playing automation. Previously the user could not change the value because
the Timer periodically reset it.
`.config/ardour5/(templates|route_templates)`.
We put as toplevel directory of the archive `templates` or
`route_templates`. Then no matter if the user imports a session template or a
route template archives, we always put them into the correct folder.
As now the user can also import route templates while the
SessionTemplateManager is visible and vice versa, we need to signal the
successful import to the corresponding template manager. Therfor we introduce
the signal TemplatesImported.
Don't use this now, except for testing as the archive format will change.
TBD:
* error handling
* check template would be overwritten by import
* dinstinguish between session and track templates
This concernes:
* LV2 states:
LV2 states are stored in the template directories and their paths are stored
int the template files using absolute paths. Therefore we have to adjust the
template-dir property of every lv2 node referring to a state dir.
* Names of route templates.
The name of the route template is stored in the first child of the xml root
node in the property `name`. This needs to be adjusted when renaming the
template.
By now we rely on that only lv2 states and the route template name need to be
adjusted on renaming a template.
Following measures:
* Split up into two classes
* TemplateDialog: the general dialog
* TemplateManager: A widget to rename and remove templates
* Make TemplateManager abstract and derive a class for session templates and
one for route templates. This is needed, as session templates and route
templates are stored in a different way. Thus we need different methods to
rename and remove them.
Goal is to a simple dialog that can rename and remove templates. This is
helpful in order to keep the template list tidy.
So far it works for session templates. Track templates tbd.
When tracks in a gain-sharing group are selected, stepping gain
up/down affected the tracks N times:
for-each selected track inc/dec gain w/grouping.
When a mix of grouped and un-grouped tracks is selected, this lead to
inconsistent gain changes.
The new approach expands the groups first. Ignoring groups is not correct
either for single selection.
Route::before_processor_for_index() uses display_to_user() which
includes the Amp.
Insert position is still be wrong with the debug mode
ProcessorBox::show_all_processors == true, but that's not a regression.
Use Editor::first_idle() which is invoked every time when a session
is loaded (via set_session). This will catch ALL successful
session loads.
Failed session-loads explicitly pop down the splash in
ARDOUR_UI::load_session.
This only leaves "abort session open" which returns to the
session-open dialog (which pops back the splash).
During ARDOUR_UI::finish(), after destroying various instances:
close_all_dialogs() -> ArdourDialog::on_response() -> GUIIdle()
The event loop recurses and may execute a previously scheduled
Editor::idle_visual_changer()
6af51b52 moved to dedicated show-editor/show-mixer actions for
keybindings because the Mixer has a dedicated handler.
For Control-surfaces a common action is still practical.
Note: This is still broken for detached windows. it currently only
toggles tabs correctly.
ARDOUR_UI::load_session() calls flush_pending() which runs
gtk_main_iteration()s until idle.
If a user selects another snapshot from the sidebar, load_session()
is called again (from a call to load session)
If pending_visual_change.pending was zero when calling idle_visual_changer
the handler_id was never reset. and the idle-handler was never called
again.
This is necessary to allow calculation of correct intersection of visible
canvas area and items for the new Item::prepare_for_render() API.
samples_per_pixel must be set first to calculate the new horizontal canvas
position in Editor::set_horizontal_position and then
WaveView::set_samples_per_pixel will eventually call
WaveView::prepare_for_render for those items that are visible on the new canvas
position at the new position.
Or if there is not a change to zoom state then call Canvas::prepare_for_render
explicitly.
Also changes so that each method is only called once during
Editor::visual_changer
First visual change will be processed as normal and then blocked until the
canvas renders the change. If further visual changes need processing then
Editor::pre_render callback will schedule another expose/redraw/render.
This prevents an issue where idle_visual_changer is called many times in
response to events(keys/motion/etc) but the canvas does not get a chance to
render any but the last one which results in a big pause/jump.
This results in a more responsive canvas and in particular a smoother and more
predictable zooming experience.
This multiplier really should be based on the "responsiveness" of the
canvas..or something. I think this is an improvement for more complex sessions
with many regions.
all float <=> string conversions are done via PBD::to_string/string_to. Either
via XMLNode::get/set_property or directly in HSV and SVAModifier classes
Saving the new ControlList interpolation methods (enum) breaks loading
the session in older version. The session-format version will
need to be increased.
Until then:
* Fader automation + region gain envelope uses linear fades
* The automation-line visible in the GUI does not match the actual fade
(the y-axis is log/exp-scale, the fade is linear)
* Adding new points on the line is not using the correct initial value
* Custom changes of interpolation mode are not available
Neither of these issues is a regression.
Trim automation is planned via SlavableAC as normal AutomationMode.
Some of this code have a revival (a special "Trim+Preview" state
before merging Automation but that has to be more general than Pan & Gain.
