... 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
Several improvements in determining how much actual disk space a
sampleblock uses. This allows us to provide how much space will
be recovered when using File -> Compact Project.
In addition, the History window now provides better space estimates.
This is highly experimental. It's defers most checkpointing
to a separate thread to see if we get better throughput and
less choppiness when applying effects.
This reenables synchronous mode by default. However, for processing
where a power cut or crash can be tolerated, synchronous and journaling
are disabled. Once the processing is complete, they are reenabled.
Types of processing that are like this are "Save As", "Backup Project",
and "Vacuuming". They all write to a separate project file while
running, so the real project file is safe.
Unfortunately, effects are back to be slow and sluggish.
I believe I've address all of the weird file corruption issues and
I'll continue to continue testing for these.
It now uses VACUUM INTO instead of the SQLite backup API
in hopes that the copies will be smaller. And VACUUM INTO
is "supposed" to be faster, but time will tell. It's easy
to put the backup API usage back in.
This also fixes a bit I missed with redoing the orphan block
handling that was reported by Paul.
And finally, it renames the AutoRecovery.cpp/.h files and AutoSaveFile
class to ProjectSerializer since the AutoSaveFile class is being
used for regular project documents now and it doesn't write to a
file anymore.
If anyone has a better idea for a name other than ProjectSerializer
feel free to change it. I hate naming things.
Preliminary tests show it to be a bit faster than the default
4KB. For a simple example, generate 2-hour chirp dropped from
11 seconds to 7 seconds. Not a lot, but...
If you try to build local SBSMS with CMake for i686, you get many error messages like this one:
audacity/lib-src/sbsms/src/fft.h:346:29: warning: SSE vector return without SSE enabled changes the ABI [-Wpsabi]
The solution is to add the option provided by SSE_FLAGS.
So, I replicated in this PR the same fix made for local soundtouch and LAME library.
