Update libdivecomputer to support the Aqualung i200c

2019-08-24T22:02:50Z

I got confirmation from Tiago Thedim Dias that my libdivecomputer patch makes BLE downloading work from the i200c, and already pushed out the libdivecomputer changes earlier. This updates the subproject in subsurface to have those changes. This also adds the bluetooth name patterns for the i300c and a few other Aqualung dive computers we hadn't added yet. That should make them show up in the bleutooth device list even without having to check the "Show all bluetooth devices" check-box. Tiago claims he didn't need that, and I wonder if we have some overly permissive match somewhere, but it's the right thing to do regardless. Signed-off-by: Linus Torvalds

Desktop: fix crash on copy & paste

2019-08-24T21:00:06Z

The constructor of PasteState was clearing an uninitialized weightsystem-table. Very silly. Initialize it instead. Fixes #2253 Reported-by: Stefan Fuchs Signed-off-by: Berthold Stoeger

Grantlee: generate vector of cylinder data on-demand

2019-08-22T17:13:40Z

Instead of generating cylinder data in the form of CylinderObjectHelper objects for every DiveObjectHelper, generate it only if needed. DiveObjectHelper is used extensively in the mobile interface, which doesn't use the cylinder data. Let's not generate unnecessary CylinderObjectHelpers in this case! Signed-off-by: Berthold Stoeger

Cleanup: turn CylinderObjectHelper into value type

2019-08-22T17:13:40Z

CylinderObjectHelper is used for structured formatting of cylinder values in grantlee types. Instead of keeping a reference to a cylinder, turn it into a value type containing the formatted strings. This should be distinctly safer, as we don't risk having stale references flying around. Moreover, we don't have to use pointers but can use containers containing plain CylinderObjectHelper. Thus, no explicit memory management is needed, making the code distinctly easier to understand. Sadly, currently grantlee does not support Q_GADGET based Q_PROPERTY. Therefore a GRANTLEE_*_LOOKUP block has to be added. This can be removed in due course, as a patch to remedy this issue is in current grantlee master. Signed-off-by: Berthold Stoeger

Cleanup: don't include dive.h in CylinderObjectHelper.hpp

2019-08-22T17:13:40Z

This only needs the declaration of cylinder_t, which is found in equipment.h Signed-off-by: Berthold Stoeger

Replace table interpolation by two line fit for CNS

2019-08-20T16:32:07Z

We used a table lookup for CNS equivalent times. Turns out the log of this table falls pretty much on a straight line for po2 <= 1.5bar. We now fit this tabel two two lines, one for <= 1.5 bar and one above. This four parameter fit has half the sum of errors squared than the five parameter fit using a fourth order polynomial. Fitting the log has the advantage that this never crosses 0, which would have the bad effect of resulting in negative CNS values as we divide by the table value. We don't adopt a maximum pO2 cut-off for the CNS calculation but rather live with the large values that the interpolation formula produces when extrapolating. Signed-off-by: Robert C. Helling
