...fix differing results on Mac by calculating only in double, so that selection
remains centered at extreme zoom-in for long projects (about 20 min.) and
selection after about 15 min.
Several other issues were also fixed (hopefully ;-)).
This is a major change to accelerator handling and keyboard
capturing. Menu shortcuts, non-menu commands, label editing,
navigation, and basically anything else were you might use
the keyboard should be thoroughly tested.
It had been causing problems in Unity for a while now and they
were missing on OSX as well in wx3. So, the old menu Open/Close
method of hiding has been removed and replaced with an event
filter/monitor which looks for wxEVT_CHAR_HOOK events to pass
key events to the handler that has the keyboard captured.
... miscellaneous direct uses of ZoomInfo::zoom to test and set zoom level.
This includes all the remaining assignments to it.
But moving TrackInfo::PositionToTime and TrackInfo::TimeToPosition into
ZoomInfo and using them is needed to eliminate many more uses.
Also #if'd out the unused AudacityProject::OnZoomToggle().
This changes the autosave XML file to a binary representation
during writing to speed up autosave processing. A lot of the
time used during autosave is a result of having to convert and
print all of the values to the XML file.
Writing the same information, but in binary format, reduces
all of that to just the bare essentials and the actual write
I/O.
During recovery, the binary file is read and converted to
the real xML representation and processing happens as it
did before.
It is a noticeable difference with very long or many tracks.
The included fix has to do with append recording.
Say you have 3 tracks and you want to append recorded audio
to the middle track. Sometime later Audacity crashes and
upon recovery, the recorded audio is actually appended to
the third track, not the second one.
This fixes that by adding an "autosaveid" to each track as
it is written to the autosave file. The same ID is written
to the recording recovery appends to the autosave file.
Then, during recovery, the IDs are matched up and the audio
gets appended to the proper track.
These autosaveid attributes are only present in the autosave
file and not in saved project files.
In particular, use an options structure for AudioIO::StartStream to simplify
calls
ControlToolBar::PlayPlayRegion also takes that structure as an argument, and a
SelectedRegion instead of two times
And other changes
This brings the builtin, LV2, and VAMP effects inline with the
Audio Units, LADSPA, and VST effects. All effects now share
a common UI.
This gives all effects (though not implemented for all):
User and factory preset capability
Preset import/export capability
Shared or private configuration options
Builtin effects can now be migrated to RTP, depending on algorithm.
LV2 effects now support graphical interfaces if the plugin supplies one.
Nyquist prompt enhanced to provide some features of the Nyquist Workbench.
It may not look like it, but this was a LOT of work, so trust me, there
WILL be problems and everything effect related should be suspect. Keep
a sharp eye (or two) open.
A 4hr track used to take about 20s to cut a few samples. This is now significantly improved, to around 3s. Leland did this by
(a) moving the size calculation to when we examine the undo history, so it isn't slowing down the edits.
(b) in size calculation, using sizes that are cached rather than going to disk to find the sizes.
(c) writing the autosave file which is to an FFIle to a string first, i.e. using XMLStringWriter as a buffer for XMLFileWriter.
Step (c) may also make autosave marginally safer, as the risk of a partially updated autosave file is reduced.
This should correct the crash and will also correct
the problem where one project's playback/capture was
being metered in another project if multiple projects
were open.
Warning...this required a small hack that allowed updating the
menus even if the toplevel frame is not the project window. This
is because with the active frame actually becomes the effect dialog
and UpdateMenus() bailed if it wasn't the project frame.
This should be removed when we get multiple effect support.
These are mostly under an EXPERIMENTAL_ #ifdef. Also has a change for the prompt string for preferences so the displayed keybinding is adjusted when in multitool mode.
Current options:
Publisher: name (the closest to what we have now)
Name (doesn't include the publisher, just a straigt up alpha sort
Publisher (creates submenus based on the publisher)
Type (creates submenus based on the type, VST, Nyquist, etc.)
And the Linux method of creating submenus based on number of items
is available to all and you can choose how menu you want per submenu.
I had to bring this back since I'd removed it when for the new effects
and I figured why limit it to only Linux...
Check it out in Preferences (effect page).
You'll also notice that the effects page is starting to talk about
plugins. That will progress further (baby steps) so bare with me
for just a bit more.
