Import was working, but the consistency checks made a few assumptions
that turned out not to be universally applicable, so they were
making a lot of unnecessary noise.
In particular F3V3 won't always create IPAPmin/max settings when in
CPAP mode or with a single IPAP setting.
Also consider ventilators to have a flex mode of "Rise Time" when
they have a rise time configured.
DreamStation ramp time and mask resistance "off" settings are now also imported.
Ventilator alarms are not yet parsed reliably enough to import at this time.
Also update Detect to retain its original behavior of letting the user
select the P-Series folder instead of the root.
Also fix what looked like a hang when backing up PRS1 files. The
progress bar still doesn't update during backup, but at least it
now says that it's backing up and the UI remains responsive.
Thanks to mjphyi for tracking this down!
gcc didn't provide very useful error messages, saying that
error: invalid conversion from ‘long int’ to ‘QDebug::Stream*’
was in qglobal.h.
But it really had to do with a few scattered #defines in OSCAR changing
nullptr to NULL (an int). Since OSCAR now requires C++11, and nullptr
is a keyword in C++11, these #defines can go.
Resolves issue #5.
Also changed layout on various pages so that spacing is not disturbed when stretching vertically
This was an attempt to shrink total dialog height, but that is so far not successful.
There was a strange interaction between git rev-parse and git diff-index when run in a batch file.
Reworked to change the way rev-parse command was handled.
Also added check to make sure git.exe was in the path.
The imported data doesn't list a brand, so the UI needs to fall back
on the loader name. Also, the purge menu wasn't getting updated
after an oximetry import.
Ideally graphs would be able to invert their Y axis without this hack, but
it works for now. It would also be good to support non-numeric labels
in the graph legend.
This changes the parsing to distinguish between the "flex pressure" reported
by single-pressure modes (which remains effectively EPAP) and the average
pressure reported by bi-level modes (which returns to its former average
pressure channel).
It looks like SaveSummaryCache() would occasionally get called elsewhere
under certain circumstances, which would cause sessions to occasionally
save, but unpredictably. Now the summary cache gets saved consistently.
This uses the miniz library, which is self-contained in a single
.c/.h pair and has an MIT license.
Swapping out the zip library should be fairly straightforward
if ever necessary.
Version number in Windows oscar.exe has first three numbers same as string and fourth as 0
Version number in Windows installer has first three numbers same as string and fourth indicates build type:
0 = release, 100=alpha, 200=beta, 300=gamma, 400=rc
Release/RC version: no sandbox
Testing releases (tagged prerelease version): -test
Development builds: -branchname (if at the head of a branch)
-(commitid) (if in a headless state)
And in the unlikely event someone tries to build a non-release version
from a tarball instead of git, its sandbox will be "-unreleased".
The bash script now adds a #define if the current checkout is
exactly on a tag, and it leaves all #defines empty if building
from a tarball.
The batch file still needs to be updated.
This removes git dependencies from everything except for version.cpp,
and removes the associated interfaces in version.h.
Since the full version string contains the branch and revision
number where applicable, the build information no longer needs
to report branch and revision separately. It also now queries
version.cpp for a more consistent and reliable build time.
Debug output of build information is also now more consistent with
less redundant code.
The full version now includes the build/git information embedded within
it as build metadata according to the Semantic Versioning 2.0.0 spec,
for example: "1.1.0-beta-1+branch-name-a1b2c3d".
Now the full version string, with all detail is always displayed
EXCEPT for release versions, in which case just the simple version
number ("1.1.0") is displayed in the primary UI.
- Main window title: simple version for release versions, full version
string otherwise
- Notifications: same as main window title
- System tray: same as main window title
- About window title: same as main window title
- About window release notes: always include full version string
- Reports: always include full version string
- Under the logo (about dialog, profile selector, new profile
window): removed, as it is largely redundant and can
interfere with the window geometry.
- Database upgrade alert: same as main window title
- Database newer alert: same as main window title
The full version string is also included within the preference and
profile .xml files, but because build metadata is ignored in version
comparisons, differences in builds will not cause any spurious
alerts. However, changes in prerelease versions will continue to
be significant, as they should be.
Previously it was reporting spurious information when the humidifier was
disconnected. Now it only reports settings details when the humidifier is
connected (the only time they're valid.)
It also now reports the humidification mode (fixed, adaptive, or heated
tube), and the heated tube temperature when appropriate.
No real change to functionality, other than confirming correct behavior,
documenting observed data and adding flags for anything new.
The ParseHumidifierSettingF0V4 function has now been renamed to
ParseHumidifierSetting60Series for accuracy.
Accordingly update ParseHumidifierSetting50Series to add a parameter
controlling whether parsed settings should be imported or not,
consistent with all other PRS1 humidifier parsers.
The ParseHumidifierSettingV2 function has now been renamed to
ParseHumidifierSetting50Series for accuracy, and the code and
parameters which had been used when 60-Series machines (incorrectly)
relied on it has been removed.
The last statistics events in each slice are now correctly imported.
Previously, in the surprising edge case where two statistic periods are
reported with the same end-of-slice timestamp, they were both being duplicated
when marking the end of the slice.
Also, there were scattered instances where the final statistics in a slice
weren't being imported at all or were being imported incorrectly. These are
now fixed as well.
No change in import behavior yet, but this will be needed to deal with a weird edge
case in which two statistic periods are reported with the same end-of-slice timestamp,
the first one intended to cover the preceding 2 minutes, the second one presumably
intended to cover the fractional second after the previous interval, though all
values are 0, so it's hard to be sure.
Because opening a profile already had a progress dialog open, the import
process during a forced rebuild wasn't appearing, so it would look like
OSCAR was hanging for as long as the import took.
Temporarily hiding the profile progress dialog resolves the issue.
This was bumped once already after the previous release version, but
bumping it again now will make sure that all beta testers are working
from data based on the current state of the PRS1 loader.
Settings are written as soon as a day is viewed, so anybody who viewed
their PRS1 data prior to the previous commit would have settings with the
channels expressly disabled. Changing the channel ID forces them to be
treated as new, and thus default to on.
Also add support for parsing and proceeding past a previously
unseen F5V0 event, though for now it's just getting swallowed
since its meaning isn't entirely clear.
This adds BND flagging to machines without waveform data, such as F3V3 (1160P)
and bricks (250P, 200X), as well as sessions for which waveform data was
unavailable. It also catches BNDs at the end of a session, which were
previously missed.
By duplicating the last reported event at its originally reported
event (clamped to the slice end time for F3V3), charts will now
correctly show the value during that last interval.
Also fix some slice sanity checks so they don't yell when F3V3
skips an event chunk.
This now correctly shows gaps in therapy and statistics when the
mask is off. It also corrects the initial statistics for some sessions
to 1 second later, when the initial mask-on slice begins 1 second
after the session starts.
Weird zero-length PB and LL events are now dropped on import, since
they wouldn't get drawn anyway and seem to be peculiar artifacts.
If there are no mask-on slices of nonzero duration, then there's not any
meaningful event or waveform data for the session. There is occasionally some
fragmentary data, but it's always less than 1 second.
When such fragmentary waveform data is present, it only contains 1-3 nonzero
samples, corresponding to 0.2s - 0.6s of data, which suggests that the
mask-on slice was really that long rather than precisely 0. As a result,
it appears that the timestamps of the mask-on/mask-off slices are just the
current value of the machine's internal clock, which only has 1-second
resolution.
But rather than embark on herculean efforts to derive a sub-second slice
duration from (only occasionally present) event or waveform data, we just
treat the session as having no detailed data.
Because summaries used to be parsed incorrectly, there was a bunch of ugly
logic that was designed to infer the session start & end times from other data.
Now that the summary parsers work, that can all go away. The only change to
imported data is that sessions ending with the mask off are now longer, to
reflect that extra time before the machine was turned off.
This now correctly shows gaps in therapy and statistics when the
mask is off. It currently only works for F3V3, since it has a
separate event chunk per slice. Other machines, which have only
a single large event chunk, will need to track the slices as
they import events.
This also highlights the issue with the last statistics in a
slice: only one data point is imported indicating the start of
a measured value, and so it appears that the data terminates then
instead of at the end of the slice (seconds to minutes later).
This fixes a regression introduced by fda9fcd1, which fixed import for
all the other machines but broke F3V3.
Also move the generation of HY/CA/OA events out of the parser and into
the importer.
This will let us create "duplicate" statistical events at the end of
a session (and eventually slice) to reflect the end time of each
measurement channel.
PRS1 statistics are reported at the end of a 2-minute interval,
but OSCAR assumes the timestamp for the statistics is their
starting timestamp.
This resolves the issue where statistics wouldn't appear for the
first two minutes of a session, and then would consistently be
2 minutes delayed.
There are still some edge cases to deal with, but the general
case is much improved.
Also clean up unused PRS1 channels and fix a regression from
9a25647c that broke unintentional leak calculation for CPAP/APAP.
Also add PRS1PressureAverageEvent to F0V4 list of supported events.
Right now this results in slightly confusing graphs, since sometimes
the IPAP/EPAP data for a machine is primarily reported by its settings
events, and for other machines by its statistics events. Also, the
"average" pressure on F0 looks like it might be effectivley EPAP in
single-pressure mode rather than the true average in bi-level mode.
Once we decide on the best presentation, we can either update the importer
or the display to show the most helpful channels for a given session.
Occasionally waveforms in a DreamStation session can be split into
multiple files. This behavior resulted in a report of missing waveform
data, and upon investigation was found 15 times out of 10,000 sample
sessions.
It looks like this happens when the machine begins writing the waveform
file before realizing that it will hit its 500-file-per-directory limit
for the remaining session files, at which point it appears to write
the rest of the waveform data along with the summary and event files
in the next directory.
The previous commit added better testing support and warning messages
for when this is encountered. This commit fixes the issue, and so
the warning is no longer necessary.
Also warn when waveform files are being skipped on import due to this
kind of splitting.
The chunks YAML now emits all unique chunks found in files with the
same session ID.
Note that a single file can contain multiple chunks covering multiple
sessions. These will all be saved in the YAML file corresponding to the
original file's name, rather than the session ID encoded in any chunk.
This slight discrepancy is intentional, since the chunk YAML is meant
to test the parsers, to verify that they correctly decode a specific
input file. When importing data into a session, we use the actual
session ID specified by each chunk. Thus the session YAML files will
be derived from the proper chunks, regardless of their original
containing file. (Well, except for waveforms, but they don't appear
to have more than one session ID per file.)
F3V3 events are formatted as waveforms (rather than a series of timestamped
events), with one chunk per mask-on slice. The previous assumption of only
a single event chunk per session meant that all events after the first slice
were getting dropped.
BiPAP AVAPS 30 (System One 60 Series) now works much better, although the data
doesn't yet show any gaps where the mask is off. Fixing that requires changes
throughout the code and not just in the PRS1 loader.
Also, LL calculation seems wrong. Perhaps the automatic calculation of
unintentional leak from total leak doesn't work for AVAPS, throwing off
automatic LL calculation? (F3V3 reports neither unintentional leakage nor
large leak events.)
This fixes the start/end times of such compliance sessions, but their
total_time is broken due to the presence of a 0-length slice.
That will require a more extensive fix of the slice system throughout
the program.
Also update the leak calculation logic to depend on the set of reported
events rather than hard-coding it based on machine family and version.
No change in functionality.
This commit adds a mapping from PRS1 events to the OSCAR channels that
should receive the data, along with the necessary supporting code to
allow for generic handling of PRS1 events as a result.
The F3V6 importer has minimal changes to partially use the new
plumbing, enough to make sure that it works and causes no change in
the imported data.
This fixes 960P-960T, which was importing both values at each interval, presumably
trampling each other. 950P didn't report it, and DreamStation never calculated it.
Also fix timed breath gain for pre-DreamStation autoSV.
F3V3 is unusual. Its events are recorded at fixed intervals like a waveform.
Its summary is recorded with absolute timestamps. Slices are each given their
own chunks in the event file.
This last oddity isn't yet handled.
While examining this, a few other importing issues have been cleaned up:
PRS1DataChunk::ParseEvents no longer needs the mode passed in as an argument,
F5V012 importers should quietly eat the newly parsed pressure
adjustment events until we can import both those and average pressure
statistics, and F5V012 importers should handle real VS events and treat
VS statistics like the other importers do.
This is very incomplete since we currently have only limited sample
data for F5V2. The events that have been verified will parse
correctly, and the rest will result in a parsing error.
There are some very strange changes in the event numbers compared
to F5V1 and F5V3, it's unclear why.
Note that F5V2 uses a gain of 0.125 like F5V3 instead of 0.1 like F5V1.
F5V1 introduces a new Hypopnea variant (event 8) with 2 data bytes.
This was previously seen in F5V3, and it's unclear how this is
different from the usual Hypopnea event (event 7, 1 data byte).
Parsing used to stop when it encountered this event, but now it
can continue through the end of the session.
F5V1 also adds a leak value in its periodic stats, also previously
seen in F5V3. PB start time and duration are now correct.
As with F5V0, now VS, LL, and EPAP adjustment are correctly parsed,
and timestamps and durations are now accurate.
The handlers were essentially copied from F5V3 and F5V0 for
consistency and cross-checking.
This fixes a lot of issues with event parsing. Now VS, LL, and EPAP
adjustment events are now correctly parsed.
And as a result the timestamps for events and overall session durations
are now accurate.
The handlers were essentially copied from F5V3 and F0V12 for
consistency and cross-checking.
No changes were intended in the imported data, but the parsers
were fantastically broken, so touching anything in the code
results in lots of differences in the output.
As a result, the imported data for F5V012 is now unstable.
On the plus side, the parser no longer bails on event 8 for F5V1.
This will almost certainly need to be split into 3 separate
functions.
