The timestamp supplied by the DV6 CPAP machine doesn't match events to the flow graph very well.
This change helps a little. Event flags may be before or after the event in the flow graph.
And, once in a long while, it's exactly right!
In theory it was useful to know why files were skipped, but in practice we
normally skip all but the most recent files, often thousands. If you had the
misfortune to have the debug pane open, you'd have to wait for an extra
minute or two for all those messages to scroll by.
If and when we can limit import scanning to files that are new or changed,
then the debug message will be useful again.
Now that properties are in the MachineInfo record, we don't need
to call PeekProperties a second time to fill out the machine
record.
Also remove some unused variables and methods from class definition.
This was a very specific edge case: when there was a single new DS1
session, the error resulting from encountering DS2 data would make
OSCAR think that it had imported zero sessions, even though it had
half-imported the DS1 session. (Those sessions would be lost after
quitting OSCAR.)
Now the loaders imported via the Data menu have access to the
unsupported/untested/brick signals and CHECK_VALUE and UNEXPECTED_VALUE
macros.
Now only devices imported via the oximetry wizard are left out,
since we need to revisit that entire workflow.
Also removed the unused Profile::Import() method.
Now all CPAP loaders have access to the unsupported/untested/brick signals
and CHECK_VALUE and UNEXPECTED_VALUE macros.
Also remove superfluous unsupported flag in MachineLoader.
Now that the post-process calcLeaks properly handles discontinuous
data, don't make the loader pretend that the machine generated
CPAP_Leak data when it didn't.
The resulting data is nearly identical, except for around edge cases
where the "correct" result is isn't clear. For example, when a
pressure changes within a 2-minute reporting interval, the
post-process calcLeaks will use that pressure when calculating
the unintended leak for that interval. The previous PRS1 loader
calculations were inconsistent, but would often apply the pressure
in place at the beginning of the 2-minute interval instead.
Either interpretation could be reasonable, but consistency is
preferred.
These minor differences aren't worth pursuing further, since the
calculated unintended leak looks dubious regardless.
This affects all CPAP/APAP/BiPAP models in the 4xx-7xx range.
In contrast, most ventilators and ASV record unintended leak
data (only the oldest ones don't), and so aren't affected by
these changes.
