2017-02-04Treat gaschanges at 1s as inital gas useGravatar Robert C. Helling
When the first leg in the planner is not cylinder 0, a gaschange event at t=1s is inserted. In the profile, we should treat that as inital gas, so no pressure information is printed for cylinder 0 that is used nominally for one second. This fixes a problem reported by Willem.

2017-02-03Correct "When merging planned dives keep all cylinders"Gravatar Robert Helling
When merging a real dive with a planned dive (for comparison), we should not try to be clever in merging similar cylinders, rather keep the union of both cylinder sets as the two versions of the dive might differ in exctly which gas and how much of it was used. Increase MAX_CYLINDERS to 20 to make room for this. We warn if we exceed this number.

2017-01-23Allow user to disable a cylinder in plannerGravatar Robert C. Helling
In the cylinder table, the last column ("use") always showed OC-GAS. Editing was enabled, but the user had to guess to enter a small integer meaning dilluent or CCR oxygen cylingder. I guess, nobody has ever done that. This patch makes this column clickable. A click toggles if the cylinder is used for planning or not. This wait it is much easier to investigate the consequences of gas loss on a plan. Signed-off-by: Robert C. Helling <helling@atdotde.de>
2017-01-12Add cylinder equipment tooltips with gas volumeGravatar Linus Torvalds
This adds tooltips for the equipment tab for each cylinder, showing the amount of gas used. When you mouse over the size and working pressure fields, the tooltip will show the amount of gas used (along with start and end gas volumes). And when you mouse over the start and end pressures, it will show the start and end gas volumes, and the Z factor used. I started doing this because of the gas volume questions in the last day or two (and a few from a few weeks ago). When even Robert Helling starts wondering about the effects of compressibility on the SAC calculation, our numbers are clearly too opaque. With these tooltips, at least you can see what went into the used gas calculations, instead of having to add debugging options to print out Z factors. [ This patch also adds a "rint()" to get the rounding right in the gas_volume() function. Although rounding to the nearst milliliter really doesn't matter, it's the right thing to do after doing FP calculations ;^] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2016-09-04Stop trying to fix up pressure sensor indexesGravatar Linus Torvalds
This removes 'fixup_dc_cylinder_index()', which was added to fix up the pressure sensor indexes from the Atomic Cobalt dive computer. Even for the Cobalt it really shouldn't matter, because the libdivecomputer backend for the Cobalt actually tries to do the right thing. See for example commit 8853a1ccd422 ("Associate the pressure samples with the primary tank.") in libdivecomputer. Some historical digging shows that the subsurface sample pressure index code came in from commit e32ba4d6d811 ("Improve tank handling for Cobalt"), dated Tue Oct 28 13:48:15 2014. And the libdivecomputer "use the right cylinder" code was around the same time (Fri Oct 10 20:29:17 2014 +0200). So I suspect that subsurface needed the fixup based on an older version of libdivecomputer. Jef's patch is a couple of weeks before, but we may not have tracked libdivecomputer religiously. The reason to remove this code is because it can (and does) mess up the sensor index when it is actually reliable, like in the multi-sensor case of the Suunto EON Steel.

2016-08-27Settings update: Clean up save user id localGravatar Tomaz Canabrava
So, prefs.save_userid_local is being set outside of a preferences set (it's set to true and false while loading the files via xml or git) and because of that I had to bypass a few method calls. When something triggers a preferences change, the application will be notified that the preferences changed, thing that I couldn't do while reading the xml or git because that should be local-only.

2016-07-21Properly pick cylinder use when merging divesGravatar Linus Torvalds
The cylinder use field was not merged when dives were merged. This is normally not noticeable, since hopefully the cylinder use should be the same anyway, but when re-downloading the dives from the EON Steel after updating it to also get cylinder use data, the dive merging threw the data away again since the original dive lacked it.

2016-05-31Make 'clear_dive()' free the primary dive computer data properlyGravatar Linus Torvalds
Our primary dive computer really is special, not just because it's the first one: it's directly embedded in the "struct dive", and so if you just walk the divecomputer list, you'll miss it, because it's not _on_ the list, it is the very head _of_ the list. We had that bug in copy_dive(), and it turns out we have it in clear_dive() too: clear_dive() would free all the dive computers on the list, but not the actual primary one. This is a minor memory leak, no more, so it's not exactly critial, but let's just do it right.

2016-04-05Fix per-cylinder SAC rate calculations when cylinder use isn't knownGravatar Linus Torvalds
John Van Ostrand reports that when he dives using two cylinders using sidemounts, the per-cylinder SAC rate display is very misleading. What happens is that since the two cylinders are used together (but without a manifold), John is alternating between the two but not actually adding gas switches in the profile. As a result, the profile looks like only one cylinder is used, even though clearly the other cylinder gets breathed down too. The per-cylinder SAC rate calculations would entirely ignore the cylinder that didn't have gas switch events to it, and looking at the info window it would look like John had a truly exceptional SAC rate. But then in the general statistics panel that actually takes the whole gas use into account, the very different real SAC rate would show up. The basic issue is that if we don't have full use information for the different cylinders, we would account the whole dive to just a partial set. We did have a special case for this, but that special case only really worked if the first cylinder truly was the only cylinder used. This patch makes us see the difference between "only one cylinder was used, and I can use the overall mean depth for it" and "more than one cylinder was used, but I don't know what the mean depths might be".

2016-04-04Start using the actual cylinder data for gas switch eventsGravatar Linus Torvalds
Now that gas switch events always have indices into the cylinder table, start using that to look up the gas mix from the cylinders rather than from the gas switch event itself. In other words, the cylinder index is now the primary data for gas switch events. This means that now as you change the cylinder information, the gas switch events will automatically update to reflect those changes. Note that on loading data from the outside (either from a xml file, from a git/cloud account, or from a dive computer), we may or may not initially have an index for the gas change event. The external data may be from an older version of subsurface, or it may be from a libdivecomputer download that just doesn't give index data at all. In that case, we will do: - if there is no index, but there is explicit gas mix information, we will look up the index based on that gas mix, picking the cylinder that has the closest mix. - if there isn't even explicit gas mix data, so we only have the event value from libdivecomputer, we will turn that value into a gasmix, and use that to look up the cylinder index as above. - if no valid cylinder information is available at all, gas switch events will just be dropped. When saving the data, we now always save the cylinder index, and the gas mix associated with that cylinder (that gas mix will be ignored on load, since the index is the primary, but it makes the event much easier to read). It is worth noting we do not modify the libdivecomputer value, even if the gasmix has changed, so that remains as a record of the original download.

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.

2016-04-04Make "is_gasmix_redundant()" more robustGravatar Linus Torvalds
The gas switch event handling is somewhat fragile, mostly because the legacy event encoding for gas switches is odd. It's also limited to whole percentages, unlike our internal gas mix model. In addition, it also ends up comparing the values to the raw permille values, which is wrong for air, and wouldn't match our O2_IN_AIR which is 209 permille (closest approximation to 20.946%). So handle air separately, since "21" really is a valid oxygen value for air, and should match 20.9%. And use the proper accessor functions to get the gasmix values.

2016-04-04Remove linear pressure interpolation detection codeGravatar Linus Torvalds
Dirk says that divinglog hasn't been doing the linear pressure interpolation for a long while, so we're doing extra dive fixups that really aren't needed any more. Also, the code is actually buggy: it only ever worked on the first cylinder anyway (because only the first cylinder pressure_delta[] would be initialized). That was probably perfectly fine in practice, since it's unlikely that many tech divers used old versions of divinglog anyway, so the bug per se isn't a reason to remove it - but it is a sign that the code was a bit hard to read, so let's get rid of it if there is no reason to maintain it or fix it.

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>
