This finally handles multiple cylinder pressures, both overlapping and
consecutive, and it seems to work on the nasty cases I've thrown at it.
Want to just track five different cylinders all at once, without any
pesky gas switch events? Sure, you can do that. It will show five
different gas pressures for your five cylinders, and they will go down
as you breathe down the cylinders.
I obviously don't have any real data for that case, but I do have a test
file with five actual cylinders that all have samples over the whole
course of the dive. The end result looks messy as hell, but what did
you expect?
HOWEVER.
The only way to do this sanely was
- actually make the "struct plot_info" have all the cylinder pressures
(so no "sensor index and pressure" - every cylinder has a pressure for
every plot info entry)
This obviously makes the plot_info much bigger. We used to have
MAX_CYLINDERS be a fairly generous 8, which seems sane. The planning
code made that 8 be 20. That seems questionable. But whatever.
The good news is that the plot-info should hopefully get freed, and
only be allocated one dive at a time, so the fact that it is big and
nasty shouldn't be a scaling issue, though.
- the "populate_pressure_information()" function had to be rewritten
quite a bit. The good news is that it's actually simpler now, although
I would not go so far as to really call it simple. It's still
complicated and suble, but now it explicitly just does one cylinder at
a time.
It *used* to have this insanely complicated "keep track of the pressure
ranges for every cylinder at once". I just couldn't stand that model
and keep my sanity, so it now just tracks one cylinder at a time, and
doesn't have an array of live data, instead the caller will just call
it for each cylinder.
- get rid of some of our hackier stuff, like the code that populates the
plot_info data code with the currently selected cylinder number, and
clears out any other pressures. That obviously does *not* work when you
may not have a single primary cylinder any more.
Now, the above sounds like all good things. Yeah, it mostly is.
BUT.
There's a few big downsides from the above:
- there's no sane way to do this as a series of small changes.
The change to make the plot_info take an array of cylinder pressures
rather than the sensor+pressure model really isn't amenable to "fix up
one use at a time". When you switch over to the new data structure
model, you have to switch over to the new way of populating the
pressure ranges. The two just go hand in hand.
- Some of our code *depended* on the "sensor+pressure" model. I fixed all
the ones I could sanely fix. There was one particular case that I just
couldn't sanely fix, and I didn't care enough about it to do something
insane.
So the only _known_ breakage is the "TankItem" profile widget. That's
the bar at the bottom of the profile that shows which cylinder is in
use right now. You'd think that would be trivial to fix up, and yes it
would be - I could just use the regular model of
firstcyl = explicit_first_cylinder(dive, dc)
.. then iterate over the gas change events to see the others ..
but the problem with the "TankItem" widget is that it does its own
model, and it has thrown away the dive and the dive computer
information. It just doesn't even know. It only knows what cylinders
there are, and the plot_info. And it just used to look at the sensor
number in the plot_info, and be done with that. That number no longer
exists.
- I have tested it, and I think the code is better, but hey, it's a
fairly large patch to some of the more complex code in our code base.
That "interpolate missing pressure fields" code really isn't pretty. It
may be prettier, but..
Anyway, without further ado, here's the patch. No sign-off yet, because I
do think people should look and comment. But I think the patch is fine,
and I'll fix anythign that anybody can find, *except* for that TankItem
thing that I will refuse to touch. That class is ugly. It needs to have
access to the actual dive.
Note how it actually does remove more lines than it adds, and that's
despite added comments etc. The code really is simpler, but there may be
cases in there that need more work.
Known missing pieces that don't currently take advantage of concurrent
cylinder pressure data:
- the momentary SAC rate coloring for dives will need more work
- dive merging (but we expect to generally normally not merge dive
computers, which is the main source of sensor data)
- actually taking advantage of different sensor data from different
dive computers
But most of all: Testing. Lots and lots of testing to find all the
corner cases.

Like the subject says. We do not want the password to be made
visible, so a switch to show it, is useless and is therefore
removed. Futher, the entry mode is set to PasswordEchoOnEdit,
which causes the passwd to be visible (for easy entry), but
can't be made visible again after save/end edit.

This does both the XML and the git save format, because the changes
really are the same, even if the actual format differs in some details.
See how the two "save_samples()" routines both do the same basic setup,
for example.
This is fairly straightforward, with the possible exception of the odd
sensor = sample->sensor[0];
default in the git pressure loading code.
That line just means that if we do *not* have an explicit cylinder index
for the pressure reading, we will always end up filling in the new
pressure as the first pressure (because the cylinder index will match the
first sensor slot).
So that makes the "add_sample_pressure()" case always do the same thing it
used to do for the legacy case: fill in the first slot. The actual sensor
index may later change, since the legacy format has a "sensor=X" key value
pair that sets the sensor, but it will also use the first sensor slot,
making it all do exactly what it used to do.
And on the other hand, if we're loading new-style data with cylinder
pressure and sensor index together, we just end up using the new semantics
for add_sample_pressure(), which tries to keep the same slot for the same
sensor, but does the right thing if we already have other pressure values.
The XML code has no such issues at all, since it can't share the cases
anyway, and we need to have different node names for the different sensor
values and cannot just have multiple "pressure" entries. Have I mentioned
how much I despise XML lately?

We had a "add_sample_pressure()" helper functions that was local to just
the libdivecomputer downloading code, but it really is applicable to
pretty much any code that adds cylinder pressure data to a sample.
Also add another helper: "legacy_format_o2pressures()" which checks the
sample data to see if we can use the legacy format, and returns the o2
pressure sensor to use for that legacy format.
Because both the XML and the git save format will need a way to save the
compatible old-style information, when possible, but save an extended
format for when we have data from multiple concurrent sensors.

This tries to sanely handle the case of a dive computer reporting
multiple cylinder pressures concurrently.
NOTE! There are various "interesting" situations that this whole issue
brings up:
- some dive computers may report more cylinder pressures than we have
slots for.
Currently we will drop such pressures on the floor if they come for
the same sample, but if they end up being spread across multiple
samples we will end up re-using the slots with different sensor
indexes.
That kind of slot re-use may or may not end up confusing other
subsurface logic - for example, make things believe there was a
cylidner change event.
- some dive computers might send only one sample at a time, but switch
*which* sample they send on a gas switch event. If they also report
the correct sensor number, we'll now start reporting that pressure in
the second slot.
This should all be fine, and is the RightThing(tm) to do, but is
different from what we used to do when we only ever used a single
slot.
- When people actually use multiple sensors, our old save format will
start to need fixing. Right now our save format comes from the CCR
model where the second sensor was always the Oxygen sensor.
We save that pressure fine (except we save it as "o2pressure" - just
an odd historical naming artifact), but we do *not* save the actual
sensor index, because in our traditional format that was always
implicit in the data ("it's the oxygen cylinder").
so while this code hopefully makes our libdivecomputer download do the
right thing, there *will* be further fallout from having multiple
cylinder pressure sensors. We're not done yet.

It appears that we used to get additional tts=0:00min tags on Seabear
parsing. I would assume these to be incorrect as there other values
right before these that look more sensible. Also the resent change to
streamline the feature of not storing repeating values causes the test
