The calculation assumes that the cylinderindex in each sample tells us
which PO2 the dive was breathing at that time. This needs to be verified
with dives where there is an actual gas switch.
No idea where to display them, yet. Far fewer people will care about this
than care about SAC - does this still rate a spot in the dive_list?
I guess I could make it part of the dive_info - but it's not editable.
It doesn't seem to fit with the equipment page (even though this is the
one editable field that is related - nitrox %)

The Diving Log temperature reading is in Fahrenheit for the samples (for
the per-dive water/air temperature it's in Celsius). But it seems to
have a bug where a lack of a sample has been turned into 32 Fahrenheit
(which is 0 celsius). This is despite the dive itself having a water
temperature of 8 degF.
Just throw away those bogus freezing temperatures. Sure, they can
happen, and ice divers are crazy - but in this case I know it's just an
error in the log, and it looks very much like a Diving Log bug.

When we change units, we need to flush any currently active dive
information in the old units, and then carefully reload it in the new
units.
Otherwise crazy stuff happens - like having current cylinder working
pressure values that are in PSI because that *used* to be the output
unit, but then interpreting those values as BAR, because we changed the
units.
Also, since we now properly import working pressure from Diving Log,
stop importing the (useless) cylinder description. The Diving Log
cylinder descriptions are things like "Alu" or "Steel". We're better
off just making up our own.
Finally, since Diving Log has cylinder size in metric, make sure that we
do the "match standard cylinder sizes" *after* we've done all the
cylinder size conversions to proper units.

Oh Gods. Why are all other scuba programs so f*&% messed up?
The Diving Log cylinder working pressure is in bar - which is all good.
But their pressure *samples* are in PSI. Why the h*ll do people mix up
units in the same damn file like that? I despair at the pure
incompetence sometimes.
I suspect the pressure samples aren't "really" in PSI: they are probably
in some user-specified units.

There's a big comment there now about what is going on. It took me a
while to understand how the crazy seven-tank uemis dive computer
information actually works.
So the Uemis computer has 4 different "tank profiles":
- single tank air (0)
- single tank nitrox (1)
- two-tank nitrox (2)
- three-tank nitrox (3)
and the computer always lists all seven tank cases (because that's how
you fill them in).
Depending on the "gas.template" you are supposed to then *use* just one
particular profile. Why the computer doesn't just give you the tanks
for that one profile, who knows? It seems to be more of the same "Uemis
dive data isn't so much about the dive, it's about dive computer state"
mentality.
So we first get the profile information, and then based on that we need
to pick the right tanks from the set of seven that we're presented with.
All clear?

This makes the xml save-file look way nicer: it's both smaller and
better organized. Using individual xml nodes for random small details
is silly.
The duration even parses exactly the same, because it still ends up
being '.depth.duration' (now it's the 'duration' attribute of the dive
node, it used to be the 'duration' child node of the dive node).

Doing per-dive cylinder start/end pressures is insane, when we can have
up to eight cylinders. The cylinder start/end pressure cannot be per
dive, it needs to be per cylinder.
This makes the save format cleaner too, we have all the cylinder data in
just one place.

This is some seriously crazy stuff. Instead of making sense as a
divelog, the uemis xml makes more sense as a "dive computer settings
dump".
And I guess I can see why they'd do that. But it makes parsing it just
incredibly annoying. The thing is more of a "these are the
configurations I support as a dive computer thing" than a "this was the
tank you were diving with".

I'll want to also add a way to override/set the cylinder type: both
manually by just setting a size in liters, and by picking from some list
of standard cylinder sizes.
For example, it looks like most of my dives are marked as having
12-liter cylinders. That is probably some default from Suunto Dive
Manager, or from whatever Dirk did. It's almost certainly not right for
any of them: as far as I know, the standard cylinders for Lahaina Divers
(which is likely most of the warm water dives) are AL72's for air, and
AL80's for Nitrox.
That would be a 10L and a 11.1L tank respectively, afaik. I don't know
what a 12-liter tank would be or where that size comes from.
Anyway, the LP85+ tank designation for some of the dives looks more
likely: that's one of the common sizes I've used for local dives. So
the size of that thing is much more probably correct.

.. and sort based on the 'time_t' value itself.
This allows us to use a more compact date format that doesn't need to
sort alphabetically, because sorting by date is always based on the date
value. So we can use just a two-digit year, and skip the seconds, to
keep the column narrow, while still sorting correctly.
Also, "Depth" is a nice header string, but it is wider than the column
itself, which makes the whole column wider than necessary. So put the
units in the header instead of in the string, keeping things narrow.

If given multiple dives at the same time, just de-dup the dives. This
happens when you've dumped the whole dive-computer several times, and
some dives show up in multiple dumps.
When de-duping, try to avoid dropping data. So if one dive has notes
attached to it, and the other one does not, pick the notes from the dive
that does have them. Obvious stuff like that.
The sample merge is also written so that it should be possible to merge
two dives. Which we don't actually do yet.

It looks like the "units.pressure" setting is only about the units that
things are *shown* in on the wrist computer: the units in the file are
always in bar (or rather, centi-bar).
Which is definitely the right thing to do, and means that we shouldn't
care about parsing the units setting. It's purely about how something
is shown, not about parsing.
That's probably true of the other units too, but let's see when I have
more data to go on.
Also, parse water temperatures and tank pressure.

We still end up guessing based on magnitude of the value, though: it
might be 'bar' or 'mbar', we end up picking one or the other based on
just how big the value is.
I should make it look at any possible explicit units too, since at least
with good xml, they exist. Of course, the only good xml I've seen so
far is the one we generate ourselves ;)

The standard way to write a date is yyyy-mm-dd, which is unambiguous and
sorts correctly.
We parsed that right in the 'datetime' case, but not in the normal date
case. And we do want to use that in our output format, exactly because
it's standard.
And also parse 'duration' for the dive duration. It's what we use when
saving, it just so happened that we ended up not parsing it right, but
then picking it up from the samples instead.

Be more careful with FP conversions, and with the Kelvin<->C offset.
And make sure to use the same names when saving as when parsing.
Now when we save a set of dives, then re-load them, and save again, the
second save image is identical to the first one.
Of course, we don't actually save everything we load, so we still do
lose information when we load and then save the result. But at least we
now don't lose the information that we *do* save.

The only thing you can do with that thing is screw things up (like
libdivecomputer did). There's no value in tracking the "filler" gas,

Did I just say "In comparison, the libdivecomputer output is nice and
sane"?
It turns out that libdivecomputer has been doing some drugs too when it
comes to gas mixes. Like showing O2 percentages as 255.0% and N2
percentages as -155.0%.
Clearly libdivecomputer uses a 'unsigned char' for oxygen percentage,
and makes "-1" be "undefined". And then it prints that non-existing mix
out, and in the process does MATH on the damn thing ("100-O2") to
"calculate" the nitrogen percentage.
Christ.
Just make the parser silently ignore the craziness, because printing out
"Strange percentage reading -155.0" a few hundred times just doesn't
make anything any better.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
The suunto xml is just completely crazy. What's the helium percentage
companion to "o2pct"? Would it be "hepct"? No. It's "hepct_0".
Ok, so they didn't number the first o2pct, which could be seen as sane:
that's the only mix value that should always exist. And they clearly
started their indexing with 0. So with multiple mixes, you'd then
expect "o2pct_1" and "hepct_1", right?
Wrong! Because XML people are crazy, the second O2 mix percentage is
obviously "o2pct_2". So the O2 percentages are one-based, with an
implicit one. But the He percentages are zero-based with an explicit
zero. So the second mix is "o2pct_2" and "hepct_1".
I'd like to ask what drugs Suunto people are on, but hey, it's a Finnish
company. No need to ask. Vodka explains everything. LOTS AND LOTS OF
VODKA.
In comparison, the libdivecomputer output is nice and sane, and uses a
'gasmix' node. Of course, now we have so many different XML nesting
nodes to check that I just made it an array of different noces. That
also allows me to mark the suunto case, so that we only do the "check
for crazy alcoholic xml entries" when it's a suunto file.
The "type of file" thing is probably a good idea for deciding on default
units too. Some day.

This requires us to change the way we match things up, because now we
can have things like
dives.dive.sample.event.time
and
dives.dive.sample.time
and they are different things (that "sample.event.time" is a 'time'
property of the 'event').
Now, this is always going to be ambiguous, since our linearized name of
the xml doesn't really care whether it's a xml node "child" or a
"property", but quite frankly, I don't care. XML just isn't worth the pain.
In fact, maybe this ambiguity can end up being a good thing. We will
parse these two different lines of XML the same way:
<dive><sample><time>50</time><depth>10.8</depth></sample></dive>
<dive><sample time="50" depth="10.8"></sample></dive>
and the attribute approach seems to be the nicer one. Maybe I'll use
that for the output format.
