... in many places where the function call will later need to be between
modules (or libraries, or the executable) and the annotation will be a necessity
to keep the linkage working on Windows.
That's all that this sweeping commit does.
... This makes it impossible to forget to include the EXPERIMENTAL definitions
(such as when cutting and pasting code) and so get unintended quiet changes of
behavior.
The EXPERIMENTAL flags are now specified instead in new file Experimental.cmake
... Comments and indentation changes only, with a small bit of code movement to
improve the sequence of items on the Doxygen page.
Comments some obscurities of template usage and of iterators (TrackIter and
TrackNodePointer).
* Don't need TrackFactory to make LabelTrack
* Don't need TrackFactory to make NoteTrack
* Don't need TrackFactory to make TimeTrack, or ZoomInfo in the factory
* Remove some forward declarations
* Rename TrackFactory as WaveTrackFactory, move it out of Track.cpp
* Need only CloseLock now, not old Lock and Unlock...
... which were for cross-project cut and paste, but they no longer work and we
need another solution. So delete much old code.
* Fix dangling reference to AudacityProject completely! ...
... in SqliteSampleBlockFactory: retain ONLY the shared pointer to
ProjectFileIO, then pass that, not project, to constructors of blocks.
completing the work of 127696879d
* Restore part of the Bug2436 fix...
... which needs the non-default arguments to WaveTrack::EmptyCopy that got lost
at d39590cf41
So that pasted WaveTracks refer to the correct SampleBlockFactory and database
for their project
But this is not yet a sufficient re-fix for the bug
* Complete the fix for cross-project copies and 2436...
... by duplicating sample blocks, in Sequence.cpp, when it is wrong just to
share them.
And to determine which case it is, see whether source and destination Sequences
have the same sample block factories when doing Copy or Paste. Duplicate
when the factories are different. Otherwise sharing is safe and more space
efficient.
This does the analogous to what DirManager::CopyBlockFile did before commit
d39590c.
* Define SampleBlockFactory replacing static members of SampleBlock...
... This will become an abstract base class
* Sequence and WaveTrack only store SampleBlockFactory not Project...
... This adds a dependency from Track to SampleBlock which temporarily enlarges
a cycle in the dependency graph
* Register a global factory of SampleBlockFactory...
... so that later we can make an abstract SampleBlockFactory, separate from the
concrete implementation in terms of sqlite, and inject the dependency at startup
avoiding static dependency
* New concrete classes SqliteSampleBlock, SqliteSampleBlockFactory...
... separated from abstract base classes and put into a new source file,
breaking dependency cycles, and perhaps allowing easy reimplementation for other
databases in the future.
Note that the new file is a header-less plug-in! Nothing depends on it. It
uses static initialization to influence the program's behavior.
* Compile dependency on sqlite3.h limited to just two .cpp files...
... these are ProjectFileIO.cpp and SqliteSampleBlock.cpp.
But there is still close cooperation of ProjectFileIO and SqliteSampleBlock.cpp.
This suggests that these files ought to be merged, and perhaps ProjectFileIO
also needs to be split into abstract and concrete classes, and there should be
another injection of a factory function at startup. That will make the choice
of database implementation even more modular.
Also removed one unnecessary inclusion of ProjectFileIO.h
* Fix crashes cutting and pasting cross-project...
... in case the source project is closed before the paste happens.
This caused destruction of the ProjectFileIO object and a closing of the sqlite
database with the sample data in it, leaving dangling references in the
SqliteSampleBlock objects.
The fix is that the SqliteSampleBlockFactory object holds a shared_ptr to the
ProjectFileIO object. So the clipboard may own WaveTracks, which own WaveClips,
which own Sequences, which own SqliteSampleBlockFactories, which keep the
ProjectFileIO and the database connection alive until the clipboard is cleared.
The consequence of the fix is delayed closing of the entire database associated
with the source project.
If the source project is reopened before the clipboard is cleared, will there
be correct concurrent access to the same persistent store? My preliminary
trials suggest this is so (reopening a saved project, deleting from it, closing
it again -- the clipboard contents are still unchanged and available).
* Eliminate unneeded back-pointer to project from non-wave Tracks...
... now that DirManager is gone
* Remove unused declarations
* SampleData::mProject was not used
* Correct ProjectFileIO::GetLibraryError
* Remove unnecessary #include directives
!!! THERE WILL NO DOUBT BE BUGS !!!
This is a big one and there's still several things to
complete. Just want to get this in the wild to start
receiving feedback.
One big thing right now is that it will NOT load pre-aup3
files. An importer is on the way for that.
... and Track::GetOwner() is publicized, so that now you can find the
the AudacityProject, if any, that owns a given Track; this will help eliminate
some uses of GetActiveProject
Now the export (should) exactly match the (selected) non greyed out tracks.
i.e. what you see and hear is what you export - no matter which mode of
mute/solo you choose.
This is now applied not just to export but also to export multiple.
Bug began at 0750f62e88
Track::SetSelected is virtual, after all, but then LabelTrack informs
LabelTrackView of selection changes by events, so that LabelTrack remains
independent of LabelTrackView.
This might make much of the rest of the guily commit unnecessary (the resetting
of selected index to -1 only lazily), but it is harmless.
... non-intrusively in the Track suclasses, registering functions instead.
For each abstract factory function (of two), build a table of concrete factory
functions, paralleling the hierarchy of Track subclesses. Dispatch using
runt time type information in the Track objects.
... and LabelTrack listens to its own events, to update certain state.
This is roundabout for now, but that state is view-related and will move into
another class.
... which will simplify later rewrites that associate selection state with
the track group, not the track.
Since LabelTrack isn't notified immediately of selection changes, instead it
always tests whether it is selected, before using the stored selected label
index.
... and eliminate some unnecessary calls to SubstitutePendingChangedTrack,
because the track and the substitute store Y and height in their shared
TrackView object.
Also make GetMinimizedHeight() virtual to avoid inclusion of TrackPanel.h in
TrackView.cpp.
... And Track no longer inherits TrackPanelCell, so be careful to rewrite
some dynamic_casts too to check instead for TrackView. Those casts won't fail
to recompile if not rewritten.
... in anticipation of making views to tracks many-to-one, but then the rulers
should be one-to-one with the views. So go through the view to get the ruler.
The ruler is really a left-hand extension for each view.
... and use std::enable_shared_from_this
Temporarily putting TrackControls.cpp back into the big s.c.c, now 59 files
Future rewriting might even eliminate all mention of those classes in
the definition of the Track classes.
