Distinguish internally between min pressure and end pressure
And don't artificially end dives on min pressure
This may be a problem for dive computers like Linus' Suunto Vyper Air
where the failure mode seems to be _high_ pressure readings (that's scary,
btw). If the transmitter fails at the end of the dive the pressure plot
ends with incorrect high pressure. But that's simply a bug with the dive
computer and not something that subsurface should hack around. Maybe we
should offer a way to edit the incorrect data points instead.
Always ending on the minimum pressure is definitely wrong as it causes
bogus plots when you do a valve shutdown during the dive (which means that
valid data gets plotted incorrectly).
We were missing the last sample (which is usually a fast ascent).
Also, reduced the velocity smoothing to 15 seconds as the 30 seconds were
hiding too much valid information
Correctly parse the braindamaged tank size information from uemis
Admittedly the cuft ratings are stupid, but still, it's not that hard.
In order to correctly describe a tank based on the cuft system you need to
know the cuft AND the working pressure. But the uemis Zurich always
assumes that the working pressure is 200bar. That's pretty close to
3000psi and therefore works "good enough" for Aluminum tanks - but in
general this will of course fail (e.g. for HP or LP tanks).
Yes Linus, gas pressure can indeed go up during a dive
At first glance it seems logical to make the ending pressure be the
lowest pressure observed during a dive. But if you do valve shut down
drills with a tech setup (where you have a fully redundant double
tank setup with two valves, two regulators and a manifold in between),
then you continue to breath from what is indeed the same "tank", but still
the valve on which your air pressure transmitter sits does get shut down
and de-pressurized. So your pressure goes down by quite a bit, and then
comes back up when the valve is turned back on.
And the ending pressure of the dive (which is used for things like the SAC
calculation) is indeed potentially higher than the lowest pressure
observed during a dive.
Allow larger tanks (change maximum from 200 to 300 cuft)
We don't handle doubles any different than single tanks - so while
200 cuft was a sane maximum size for a tank, once you dive with
doubles this logic fails.
We may or may not decide to implement special handling for doubles at some
point, but for now simply allow for tanks all the way up to double-150.

And ever since the dive list was made much wider and moved below the

both a reasonable plot window and several dives visible at the same
time.
The solution seems to be to just make the dive list be a notebook page.
That makes the default layout very dense.
At the same time, when you have the pixels, it's horrible, because you
would want to see the dive list and move between dives while at the same
time also seeing the dive profile change. But that is solvable by
simply making the dive list notebook page be detachable, so if you have
a nice big screen, just detach the dive list page and now you have
independent windows for the dive list and the dive info.
NOTE! I don't have any way to re-attach the dang thing. I think I'd
need to learn about drag-and-drop targets etc. So once you've detached
the dive list, it stays detached.
Update Mares IconHd parsing to current libdivecomputer interface
The libdivecomputer interfaces are pure crap. There are no generic
"open the dive computer" or "create a parser for the dive computer"
interfaces, instead each dive computer you support has its own open and
parser generator interface.
And they change. Happily fairly seldom, but they change. And two days
ago, Jef changed the interface for the Mares Icon HD computer in order
to support the newer HD Net Ready variant.
I've asked Jef to make a sane interface for "open the dive computer" and
"just create the parser" for libdivecomputer, but he claims that he
cannot just track the device model details internally. Which is
obviously a completely bogus claim, since the way *we* track the model
details is to just feed it back from the silly event.
libdivecomputer should just do that internally and not bother us with
its crazy internal model numbers. But whatever.
In the meantime, work around this braindamage, and hope that
libdivecomputer comes to its senses some day.
Stop libdivecomputer import when we start seeing old dives
I don't know about other dive computers, but the Suunto Vyper Air is
slow as hell to import all the dives from. And libdivecomputer seems to
be importing dives "most recent first", so this just makes it stop
importing dives when it finds a dive that we've already seen.
Caveat: libdivecomputer has this fancy notion of "dive fingerprints",
and claims that's the way to do things. That seems to be overly
complicated, and not worth the bother.
If you worry about the import finishing early due to already having some
dives with the same date in your dive list, just import starting from an
empty state, and thus get a pure "dive computer only" state with no
early out. Then you can just load the old dives afterwards, and depend
on subsurface merging any duplicates.
But for normal operation, when you just want to import a couple of new
dives from your dive computer, the "exit import early when you see a
duplicate" is the right thing to do.
Add a GtkEntry to allow editing of the device name
Ok, so some file chooser widget with a popup dialog would have been more

horrible when populated with /dev entries, and I don't think there is
any sane filter function.
So this works, and means that you don't *have* to recompile the whole
program just because you have your dive computer on something else than
a USB serial line.
I suspect I should save the default name as a config variable too.
Maybe a setting in the preferences dialog.
It's really just about the logo, but whatever. Dirk tells me I need one
of these in order to call it 1.0. And I'm not going to fall into the
trap of thinking that 1.0 needs to be something polished, it just needs
to be working well enough..
This is *really* ugly. We really should just create some kind of widget
that when moused over will show the event. Or something. Rather than
putting text on top of other text: the events - when they happen - are
usually bunched together (PO2 warnings, max depth, fast ascent leading
to mandatory safety stop, you name it).
But at least this way we see that the data is there, even if we see it

dive from a dive computer? Yeah, they exist in the libdivelog xml files
too. So ignore them when we see them there too.
As reported by Mauro Dreissig, the progress bar doesn't work and causes
a SIGSEGV due to a missing allocation. The code broke when Dirk
separated out the GUI from the core code, and I hadn't tried
divecomputer downloads since.
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 %)
