[Audacity-devel] Update: Automatic crash recovery

[Markus M. <me...@me...>]

Hi everyone,

the following has now been implemented and committed:

* When an auto-recovered .aup file is opened, it is now checked for
orphaned/missing blockfiles etc. and silently and safely corrected
without doing damage to the original project. When the project is saved,
all orphaned blockfiles (those would belong to the old, crashed project)
are automatically deleted. This means, a saved, recovered project should
now automatically be free from defects

* While recording, auto-recovery information is now collected (I tried
to make the changes in some core files as unobtrusive as possible), but
the saving and loading of this information is not yet implemented. If
you're interested in how it works, you can remove the commenting from
the printfs at the end of Project.cpp

Two other small fixes have been commited:

* AudioIO now checks the return values of some Portaudio functions now
more thoroughly and fails cleanly if e.g, PortAudio finds a device but
cannot retrieve any info on it. This should avoid crashes some users
have experienced with ALSA on Linux

* When a project is now overwritten by save-as, orphaned blockfiles are
automatically cleared from the project folder
