2018-05-14Simplify the bailout detection functions.Gravatar Willem Ferguson
Function peek_next_divemodechange() is redundant if get_next_divemodechange() has one additional parameter. Calls to get_next_divemodechange() were updated in divelist.c, plannernotes.c and profile.c. Signed-off-by: Willem Ferguson <willemferguson@zoology.up.ac.za>
2018-05-14Implement bailout outside of the dive plannerGravatar Willem Ferguson
This is the second step for implementing bailout. The indirect calls to fill_pressures through add_segment() (in deco.c) are addressed. Bailout is now fully implemented in the dive log but not in the dive planner. 1) The parameters to add_segment() are changed to take a divemode as the second last parameter, and not a *dive. 2) Call to add_segment() in profile.c and in divelist.c are adapted. In divelist.c some calls to add_segment were left using dc-> divemode instead of possible bailout. This appears tp be the most appropriate route. 3) The functions get_divemode_from_time() and get_next_divemodechange() in dive.c have had some small changes. 4) The calls to get_segment(0 in planner.c were changed to reflect the new parameter list, but not updated to reflect bailout. This is the next step. Signed-off-by: Willem Ferguson <willemferguson@zoology.up.ac.za>
2018-05-14Incorporate bailout events in CCR & PSCR gas calculations.Gravatar Willem Ferguson
This is a first step to interpret bailout events. 1) The event structures have a new attribute: divemode. Currently interpreted dive modes are OC, CCR, PSCR. 2) When doing fill_pressures(), the calculation is aware of divemode. When divemode is OC (==bailout), then the appropriate calculations of gas pressures are done. 3) Two new functions get_next_divemodechange() and get_divemode_at_time() are created to find divemode changes in the events linked list and to determine the dive mode at any point during the dive. 4) fill_pressures gets a small amendment to facilitate the correct calculations, depending on divemode. The cases where fill_pressures() is used *outside the planner* are changed. The result is that, for dives with bailout, the correct gas pressures are shown on the dive profile. The deco for bailout dives is not yet correct. This is the next step. Signed-off-by: Willem Ferguson <willemferguson@zoology.up.ac.za>

2018-04-28Plot OC-pO2 graph for SCR divesGravatar Willem Ferguson
This commit allows plotting the OC-equivalent pO2 graph for PSCR dives. This happens in both the cases where there is no external O2-monitoring AND when there is external pO2 monitoring. The calculations are only done for PSCR dives and is achieved as follows: 1) Within plot-info create a pressure-t called OC_pO2 in profile.h and populate this variable with the open-circuit pO2 values in profile.c. 2) Create a new partialPressureGasItem ocpo2GasItem in profilewidget2.h and, in profilewidget2.cpp, initialise it to read the plot-info OC_pO2 values and enable its display by using the setVisible method. The diveplotdatamodel was also touched in order to achieve this. 3) Create a pref button that controls the display of OC-pO2 for SCR dives 4) Change the colour of the OC-pO2 grpah to orange 5) Change the connection of the crr_OC_pO2 signal to be appropriate 6) rename the OC_pO2 attribute to scr_OC-pO2 Signed-off-by: Willem Ferguson <willemferguson@zoology.up.ac.za>

2017-11-25Localize global planner stateGravatar Robert C. Helling
For UI responsiveness, we need to be able to run the planner in the background. This needs the planner state to be localized (and we need to pass a pointer around). In order to not let too many lines overrun (and to save typing in the future) I have renamed instances of struct deco_state to ds. Yes this should have gone to a separate commit but I accidentally commit --amend'ed it. Computing of planner variations is temporarily disabled.

2017-11-17Don't show cylinder pressures for other dive computersGravatar Linus Torvalds
Stefan Fuchs points out that sometimes you get cylinder duplication when you merge dives, particularly with a planned dive. For example, if we had different manual pressures in the two different dives, the cylinders will be kept separate. But that also means that we don't want to plot the pressures from those other cylinders that came from another dive and are now associated with another dive computer. Change the "seen" logic for the cylinder to ignore cylinders that are only mentioned by other dive computers than the active one.

2017-11-08VPMB: calculate deco_time assuming final ascent always takes the same timeGravatar Rick Walsh
If we consider the actual time to ascend from the final stop when calculating deco_time, then slowing the final ascent can lead to the final stop being extended, which is completely nonsensical. For consistency with the original VPMB implementation, we can't ignore the final ascent time completely, but if we assume it is always the same (take default ascent rate of 9m/min) then slower the final ascent won't lead to a longer final stop.

2017-09-15Properly clear sensor pressure data for synthetic plotinfo entriesGravatar Linus Torvalds
We only cleared the first sensor data when we created new synthetic plot info entries, because we only used to have one (well, we had the o2 data, but apparently nobody ever noticed that it didn't get properly interpolated, probably because people who have CCR dives with o2 pressures are few, and the pressure drops are gradual anyway). Clear all the pressure data, so that the interpolation code doesn't think we have some existing real sensor data for the plot info entries in between proper sample entries.

2017-07-30For more manual gas pressure detailsGravatar Linus Torvalds
So the manual gas pressure case keeps showing issues, and in many ways it really is a fairly complex thing, since it needs interpolation of the intermediate pressures - possibly over several gas changes. So you might have beginning and ending pressures for one cylinder, but then use another cylinder in between. We've historically got all the code to do this, but the big rewrite for multiple cylinder pressures didn't get all the details right, and so here's a few more fixes for the case that was shown by a dive by Robert Helling. Hopefully we're approaching the old code situation, except now with concurrent gas pressure handling support.

2017-07-30Fix another cylinder pressure plotting special caseGravatar Linus Torvalds
The core to plot manually entered pressures without any sample data did the obvious thing: it ended the pressures at the end of the dive as indicated by the last sample. However, that obvious thing didn't actually work, because sometimes the last sample is long long after the dive has actually ended, and we have no plot_info data for that. This depends on the dive computer used: most dive computers will not report samples after the end (even if they may internally remember them in case the diver just came up to the surface temporarily), but some definitely do. The OSTC3 is a prime example of that. Anyway, the code was fragile and wrong - even if passed a time past the end of the plot_info data, "add_plot_pressure()" should just have associated that with the last entry instead. Which also allows us to simplify the whole endtime logic entirely, and just use INT_MAX for it. Gaetan Bisson's test-case also showed another oddity: we would plot the gas pressure even for cylinders that had no has use (ie beginning and ending pressures were the same). That's kind of pointless in so many ways. So limit the manual pressure population to cylinders that actually have seen use.

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.

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.
