2016-08-29Teach 'interpolate()' about zero-sized rangesGravatar Linus Torvalds
No, they don't make sense. We should normally not have multiple samples that are on the same second. But they seem to happen on the EON Steel under some circumstances, and instead of dividing by zero when trying to interpolate across such a sample, do something sane.

2016-07-09Planner: automate calculation of best mix for max depthGravatar Rick Walsh
Add option to calculate the best mix portion of O2 and He for the dive's max depth if the user enters * in the MOD and MND cylinder fields. Gas portions are automatically recalculated if the max depth of the dive changes. Signed-off-by: Rick Walsh <rickmwalsh@gmail.com> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2016-07-09Have divedatapoint store cylinder id instead of gasmixGravatar Rick Walsh
Determining the correct cylinder index from a known gas mix can be complicated, but it is trivial to look up the gasmix from the cylinder_t structure. It makes sense to remember which cylinder is being used. This simplifies handling changing a cylinder's gas mix, either directly by the user, or indirectly in the planner. It also permits tracking of multiple cylinders of the same mix, e.g. independent twins / sidemount. Signed-off-by: Rick Walsh <rickmwalsh@gmail.com> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2016-04-05QML UI: don't fetch the remote twice when loadingGravatar Dirk Hohndel
We first check the sha to see if we want to load at all. But at that point we already have the repository and the branch and we have synced with the remote. So when we decide that we need to reload from storage, we don't need to repeat those steps, instead we can go directly to the git load. For that to work we need to pass the repository pointer and the branch name back to the caller so that we can directly call git_load_dives(). Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
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 cylinder_nodata() take a const cylinder pointerGravatar Linus Torvalds
Some of the gas mix cleanups I'm doing are in code that uses const pointers, and wants to use this. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
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>
