I refactored the code into AudacityApp with a new timer. This is provisional pending discussion - if it is decided that it should go somewhere else I will move it.
Fixed bug in resetting mPrevT1. That caused remaining issue noted in Bug 258 comments 2 and 3.
Moved call to UpdateMeters from TrackPanel::OnTimer() to audacityAudioCallback, where it calls gAudioIO->mOutputMeter->UpdateDisplay(), so the updates are synchronized with Meter Toolbar updates.
Removed unnecessary call to MixerBoard::UpdateMeters() in AudacityProject::UpdateMixerBoard().
Various cleanup.
When looking for default curves, EQDefaultCurves.xml is searched for in the DataDir first, then the exeDir, then the error dialog is popped up.
Error dialog stays open while user visits web site to get EQDefaultCurves.xml.
The 'normal' set of curves EQCurves.xml is still in DataDir.
Substantial changes to MixerTrackCluster::UpdateMeter() such that it now uses the original Meter::UpdateDisplay() rather than the override I wrote.
I think some of the ideas in the override were good though, mainly to use max and rms from blockfiles rather than passing interleaved sample buffer to Meter::UpdateDisplay() and having it recalculate those values. May be worth revisiting. Definitely worth testing for performance issues relative to 1.3.12.
Also, since all we're doing here is updating the meters, maybe we should remove it from TrackPanel::OnTimer() and do that in audacityAudioCallback where it calls gAudioIO->mOutputMeter->UpdateDisplay(). Thread issues?
DirManager::ProjectFSCK (project check):
Made the enumerations interleaved with handling, because,
for example, user choosing to replace missing aliased block files with silence
needs to put in SilentBlockFiles and delete the corresponding auf files,
so those would then not be cumulated in missingAliasBlockFileHash.
We still do the FindX methods outside the conditionals,
so the log always shows all found errors.
Moved check for orphan files to last, so user first has a chance to get
messages about missing files that user may have mistakenly renamed
(and the renamed ones would appear to be orphans).
Re-ordered user choices for orphan files dialog to safest-to-boldest.
Changed FSCKstatus_CLOSEREQ and FSCKstatus_CHANGED to be integers rather
than binary flags. They were never returned with both in the result, nor used that way.
Made the project check log warnings use full paths instead of just file names.
Removed close box and system menu from MultiDialog, so that project check dialogs cannot just be closed. User has to decide on one of the choices.
Fixed some handling in AudacityProject::OnShowLog(). If the log was already showing before MultiDialog came up, it froze because it was not re-enabled.
