Using gcc option "-Wfloat-conversion" is useful to catch
potential conversion errors (where lrint should be used).
rint returns double and still raises the same warning,
this is why this change updates all rint calls to lrint.
In few places, where input type is a float, corresponding
lrinf is used.

This patch eliminates the difference between the saturation and
desaturation rates. This was probably once meant as a conservative
measure but the desaturation rate was increased rather than the
saturation rate (which is probably a typo, as reported by Stefan).
Since there is no good basis for this anyway, this patch sets
both factors to 1.0 (and if accepted the whole factor business
should be removed).
This makes our deco times slightly longer. But in the past,
we had introduced a 1.2% fudge factor in the critical radius
calculation to add conservatism and match the benchmark better.
Removing this fudge factor brings us close to the benchmarks.
Expected test values updated.

We used to always create a new dive site structure when loading dive
site data from XML.
That is completely bogus, because it can (and does) create duplicate
dive sites with the same UUID. Which makes the whole UUID pointless.
So instead, look up the existing dive site associated with the UUID
loaded from the XML, and try to merge the data properly if we already
had dive site information for that UUID.

The Qt model sorting for the dive date was using a unsigned number,
which doesn't work for dates before 1970.
Also, the dive date parsing got the year 1900 wrong. Not that we really
care, because other parts of date handling will screw up with any date
before the year 1904. So if you claim to be diving before 1904, you get
basically random behavior.

In the beginning of the diveplan, divedatapoints of zero
duration indicate available gases with the depth giving
the suggested switch depth. Zero-duration datapoints in

thus be ignored when composing the gaslist.

This makes some further updates to the new cylinder merging code:
- avoid re-using the cylinder if the usage type (OC/diluent/O2) is
different between the two dives, even if the gasmix might be the
same.
- avoid re-using a cylinder if the user has manually added pressure
data for it (and the pressures don't match)
- when deciding to reuse a cylinder, make sure that we merge as much of
the type information as makes sense.
This will potentially result in more cylinders that might need manual
cleanup, but at least we won't be throwing out user data. And in most
cases where merging happens, none of this is an issue (because the data
comes fresh from a dive computer, and won't have been manually edited to
trigger the new rules).
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
The old cylinder merging code depended on the preferred dive having all
the cylinders, and the newly merged dive was just forced to pick from
that existing set of cylinders.
That worked ok if you have a "main" dive computer that you have all the
gases programmed for, and you download that first, and then you download
any secondary data later.
But it completely messed up if the second dive computer had gases that
the first one didn't know about, and just basically ended up doing
random things.
This rewrites the whole thing to actually try to create a union of the
two sets of cylinders when merging, with sane matching so that if the
cylinders match you won't get duplicates.
Miika Turkia hit this when he only used one gas, but had several gases
defined in his OSTC that he downloaded after his Vyper (with had just
the single gas defined).
This should fix that case (at least it does for my xml merging test-case
that showed the same problem after some munging).

We had hardcoded the exact translation of the event numbers. They

New libdivecomputer versions use DC_SAMPLE_GASMIX to indicate a gas
change (which contains the cylinder index we're changing to) rather than
SAMPLE_EVENT_GASCHANGE*.
Unlike the old GASCHANGE model, and despite the name, DC_SAMPLE_GASMIX
does not actually say what the mix is, it only specifies a cylinder
index. We had already extended SAMPLE_EVENT_GASCHANGE2 to have the
cylinder index in the otherwise unused "flags" field, so this is not all
that different from what we used to do.
And subsurface internally already had the logic that "if we know what
the cylinder index is, take the gas mix from the cylinder data", so
we've already been able to transparently use _either_ the actual gas mix
or the cylinder index to show the event.
But we do want to make it an event rather than some sample data, because
we want to show it as such in the profile. But because we are happy
with just the cylinder index, we'll just translate the DC_SAMPLE_GASMIX
thing to the SAMPLE_EVENT_GASCHANGE2 event, and nothing really changes
for subsurface.
libdivecomputer has made other changes, like indicating the initial
cylinder index with an early DC_SAMPLE_GASMIX report, but we've seen
that before too (in the form of early SAMPLE_EVENT_GASCHANGE events), so
that doesn't really end up changing anything for us either.
HOWEVER, one thing that is worth noticing: do *not* apply this patch and
then use an old libdivecomputer library that sends both the
DC_SAMPLE_GASMIX samples _and_ the deprecated SAMPLE_EVENT_GASCHANGE
events. It will all *work*, but since subsurface will take either,
you'll then get duplicate gas mix events.
It's not like that is in any way fatal, but it might be a bit confusing.

This adds tooltips for the equipment tab for each cylinder, showing the

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
