2017-07-28Fix manual pressures for cylinders with no gas switchesGravatar Linus Torvalds
"If it hasn't been tested, it doesn't work". All my testing of the multiple sensor pressures have been with some reasonably "interesting" dives: they actually *have* sensor pressures. But that test coverage means that I missed the truly trivial case of just having manual pressures for a single cylinder. Because there's only a single cylinder, it doesn't have any cylinder changes, and because there were no cylinder changes, it never filled in the use range for that cylinder. So then it never showed the pressure profile at all. Duh. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2017-07-28Calculate momentary SAC rates with the right gasesGravatar Linus Torvalds
The momentary SAC rate got broken by the multiple ressure handling too, and always used just the first cylinder. This uses the new "get_gasmix()" helper to see what you're breathing, and will do the SAC rate over all the cylinders that contain that gas. So it should now DTRT even for sidemount diving (assuming you had the same gas in the sidemount cylinders). NOTE! We could just do the SAC rate over *all* the gases you have pressures for, and maybe that's the right thing to do. The ones you are not breating from shouldn't have their pressure change. But maybe some people add their drysuit argon gas to the gas list? So this may need more work, but it's a step in the right direction.

2017-07-28Use the right gasmix for deco calculationsGravatar Linus Torvalds
In commit e1b880f4 "Profile support for multiple concurrent pressure sensors" I had mindlessly hacked away at some of the sensor lookups from the plot entries to make it all build, and forgotten about my butchery. Thankfully Jan and Davide noticed in their multi-cylinder deco dives that the deco calculations were no longer correct. This uses the newly introduced "get_gasmix()" helper to look up the currently breathing gasmix, and fixes the deco calculations.

2017-07-27Profile support for multiple concurrent pressure sensorsGravatar Linus Torvalds
This finally handles multiple cylinder pressures, both overlapping and consecutive, and it seems to work on the nasty cases I've thrown at it. Want to just track five different cylinders all at once, without any pesky gas switch events? Sure, you can do that. It will show five different gas pressures for your five cylinders, and they will go down as you breathe down the cylinders. I obviously don't have any real data for that case, but I do have a test file with five actual cylinders that all have samples over the whole course of the dive. The end result looks messy as hell, but what did you expect? HOWEVER. The only way to do this sanely was - actually make the "struct plot_info" have all the cylinder pressures (so no "sensor index and pressure" - every cylinder has a pressure for every plot info entry) This obviously makes the plot_info much bigger. We used to have MAX_CYLINDERS be a fairly generous 8, which seems sane. The planning code made that 8 be 20. That seems questionable. But whatever. The good news is that the plot-info should hopefully get freed, and only be allocated one dive at a time, so the fact that it is big and nasty shouldn't be a scaling issue, though. - the "populate_pressure_information()" function had to be rewritten quite a bit. The good news is that it's actually simpler now, although I would not go so far as to really call it simple. It's still complicated and suble, but now it explicitly just does one cylinder at a time. It *used* to have this insanely complicated "keep track of the pressure ranges for every cylinder at once". I just couldn't stand that model and keep my sanity, so it now just tracks one cylinder at a time, and doesn't have an array of live data, instead the caller will just call it for each cylinder. - get rid of some of our hackier stuff, like the code that populates the plot_info data code with the currently selected cylinder number, and clears out any other pressures. That obviously does *not* work when you may not have a single primary cylinder any more. Now, the above sounds like all good things. Yeah, it mostly is. BUT. There's a few big downsides from the above: - there's no sane way to do this as a series of small changes. The change to make the plot_info take an array of cylinder pressures rather than the sensor+pressure model really isn't amenable to "fix up one use at a time". When you switch over to the new data structure model, you have to switch over to the new way of populating the pressure ranges. The two just go hand in hand. - Some of our code *depended* on the "sensor+pressure" model. I fixed all the ones I could sanely fix. There was one particular case that I just couldn't sanely fix, and I didn't care enough about it to do something insane. So the only _known_ breakage is the "TankItem" profile widget. That's the bar at the bottom of the profile that shows which cylinder is in use right now. You'd think that would be trivial to fix up, and yes it would be - I could just use the regular model of firstcyl = explicit_first_cylinder(dive, dc) .. then iterate over the gas change events to see the others .. but the problem with the "TankItem" widget is that it does its own model, and it has thrown away the dive and the dive computer information. It just doesn't even know. It only knows what cylinders there are, and the plot_info. And it just used to look at the sensor number in the plot_info, and be done with that. That number no longer exists. - I have tested it, and I think the code is better, but hey, it's a fairly large patch to some of the more complex code in our code base. That "interpolate missing pressure fields" code really isn't pretty. It may be prettier, but.. Anyway, without further ado, here's the patch. No sign-off yet, because I do think people should look and comment. But I think the patch is fine, and I'll fix anythign that anybody can find, *except* for that TankItem thing that I will refuse to touch. That class is ugly. It needs to have access to the actual dive. Note how it actually does remove more lines than it adds, and that's despite added comments etc. The code really is simpler, but there may be cases in there that need more work. Known missing pieces that don't currently take advantage of concurrent cylinder pressure data: - the momentary SAC rate coloring for dives will need more work - dive merging (but we expect to generally normally not merge dive computers, which is the main source of sensor data) - actually taking advantage of different sensor data from different dive computers But most of all: Testing. Lots and lots of testing to find all the corner cases. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2017-07-21Start cleaning up sensor indexing for multiple sensorsGravatar Linus Torvalds
This is a very timid start at making us actually use multiple sensors without the magical special case for just CCR oxygen tracking. It mainly does: - turn the "sample->sensor" index into an array of two indexes, to match the pressures themselves. - get rid of dive->{oxygen_cylinder_index,diluent_cylinder_index}, since a CCR dive should now simply set the sample->sensor[] indices correctly instead. - in a couple of places, start actually looping over the sensors rather than special-case the O2 case (although often the small "loops" are just unrolled, since it's just two cases. but in many cases we still end up only covering the zero sensor case, because the CCR O2 sensor code coverage was fairly limited. It's entirely possible (even likely) that this migth break some existing case: it tries to be a fairly direct ("stupid") translation of the old code, but unlike the preparatory patch this does actually does change some semantics. For example, right now the git loader code assumes that if the git save data contains a o2pressure entry, it just hardcodes the O2 sensor index to 1. In fact, one issue is going to simply be that our file formats do not have that multiple sensor format, but instead had very clearly encoded things as being the CCR O2 pressure sensor. But this is hopefully close to usable, and I will need feedback (and maybe test cases) from people who have existing CCR dives with pressure data.

2017-07-20Unify sample pressure and o2pressure as pressure[2] arrayGravatar Linus Torvalds
We currently carry two pressures around for all the samples and plot info, but the second pressure is reserved for CCR dives as the O2 cylinder pressure. That's kind of annoying when we *could* use it for regular sidemount dives as the secondary pressure. So start prepping for that instead: don't make it "pressure" and "o2pressure", make it just be an array of two pressure values. NOTE! This is purely mindless prepwork. It literally just does a search-and-replace, keeping the exact same semantics, so "pressure[1]" is still just O2 pressure. But at some future date, we can now start using it for a second sensor value for sidemount instead.

2016-06-01Make sure all dive computer events are represented in the plot_info dataGravatar Linus Torvalds
We could create a plot_info data that didn't contain all the time slots for the events fromt he dive computer, which would terminally confuse the plotting of the event profile widgets because it couldn't match up the event with the dive plot data model. So for example, in DiveEventItem::recalculatePos(), when the code tries to figure out the spot in the data model, it could fail, and then try to hide the event (because without the data model information it doesn't know where it should go). But that hiding would then not match the logic in DiveEventItem::shouldBeHidden(), and the event would end up being shown in the upper left-hand corner of the profile after all. The reason the plot_info data wouldn't contain the time slots is that the slots are allocated primarily for the sample data, and then the events would be added in between sample data in populate_plot_entries(). But since we'd only add the event pointer *between* samples, that would mean that events after the last samples would not get plot-info points allocated to them. That issue was exacerbated by how we also truncate uninteresting samples at the end when some dive computers end up giving a long stream (possibly several minutes) of "at the surface" events before they finally turn off logging. This makes sure that we take the event timestamps into account for the "maxtime" calculation, and also that we finish populating the plot_info data with any final event timestamps. Now all the events will have a matching plot_info entry. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2016-04-11Fix time of first ceiling calculationGravatar Robert C. Helling
In our verision of VPM-B for real dives, we take as the deco time the difference between the time of the deepest ceiling and the time when the ceiling clears. When the display of ceilings was set to multiples of 3m this was confused, as the maximum finder had issues: First of all, it updated the time when the ceiling was the same (which was almost always the case for stepped ceilings) but changing >= to > was not enough, since then the first time a deepest stepped ceiling was reached was used. This patch uses the actual ceiling (not rounded to the next integer multiple of 3m) for this calculation to get rid of this problem. Signed-off-by: Robert C. Helling <helling@atdotde.de>
2016-04-04Make gas change events always have a cylinder indexGravatar Linus Torvalds
In commit df4e26c8757a ("Start sanitizing gaschange event information") back about a year and a half ago, I started sanitizing the gas switch event data, allowing gas switches to be associated with a particular cylinder index rather than just the gas mix that is switched to. But that initial step only _allowed_ a gas switch event to be associated with a particular cylinder, the primary model was still to just specify the mix. This finally takes the next step, and *always* associates a gas switch event with a particular cylinder. Instead of then looking up the cylinder by trying to match gas mixes at runtime, subsurface now looks it up when loading the dive initially as part of the dive fixup code. The switch event still has an a separate gas mix associated with it, but this patch also starts preparing for entirely relying on the gas mix in the cylinder itself, by starting to pass in not just the event but also the dive pointer to the routines that look up gas mix details.

2016-04-04Move subsurface-core to core and qt-mobile to mobile-widgetsGravatar Dirk Hohndel
Having subsurface-core as a directory name really messes with autocomplete and is obviously redundant. Simmilarly, qt-mobile caused an autocomplete conflict and also was inconsistent with the desktop-widget name for the directory containing the "other" UI. And while cleaning up the resulting change in the path name for include files, I decided to clean up those even more to make them consistent overall. This could have been handled in more commits, but since this requires a make clean before the build, it seemed more sensible to do it all in one. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
