The create_plot_info_new() function releases old plot data. This

The ProfileWidget2 did that by a memset, but other parts of the code

Therefore, introduce a init_plot_info() function and call that when
generating a plot_info struct. Constructors would make this so much
easier - but since this is called from C, we can't use them.

Select the proper dives after the add, remove, split and merge
dives commands on undo *and* redo. Generally, select the added
dives. For undo of add, remember the pre-addition selection.
For redo of remove, select the closest dive to the first removed
dive.
The biggest part of the commit is the signal-interface between
the dive commands and the dive-list model and dive-list view.
This is done in two steps:
1) To the DiveTripModel in batches of trips. The dive trip model
transforms the dives into indices.
2) To the DiveListView. The DiveListView has to translate the
DiveTripModel indexes to actual indexes via its QSortFilterProxy-
model.
For code-reuse, derive all divelist-changing commands from a new base-class,
which has a flag that describes whether the divelist changed. The helper
functions which add and remove dives are made members of the base class and
set the flag is a selected dive is added or removed.
To properly detect when the current dive was deleted it
became necessary to turn the current dive from an index
to a pointer, because indices are not stable.
Unfortunately, in some cases an index was expected and these
places now have to transform the dive into an index. These
should be converted in due course.

Commit f5b11daffd changed gasmix
arguments and return values to be passed by value instead of
using pointers.
Notably, get_gasmix() is fed a default-value and returns a
new value. In the old code, NULL was passed in in a first
loop iteration and non-NULL was always returned in the first
iteration. Thus, an equality comparison of passed-in an
returned gasmix would always fail in the first loop iteration.
The new code passed in air as default. Now if air was also
returned, then the matching gases were not calculated in
calculate_sac(). To revert to the old behavior, pass in
an invalid gasmix.
Moreover, give names to the invalid and air gasmixes.

In a previous commit, the get_gasmix_* functions were changed to
return by value. For consistency, also pass gasmix by value.
Note that on common 64-bit platforms struct gasmix is the size
of a pointer [2 * 32 bit vs. 64 bit] and therefore uses the
same space on the stack. On 32-bit platforms, the stack use
is probably doubled, but in return a dereference is avoided.
Supporting arbitrary gas-mixes (H2, Ar, ...) will be such an
invasive change that going back to pointers is probably the
least of our worries.
This commit is a step in const-ifying input parameters (passing
by value is the ultimate way of signaling that the input parameter

Currently, get_gasmix_from_event() and get_gasmix() return pointers
to either static or to (possibly changing) dive data. This seems like
a dangerous practice and the returned data should be used immediately.
Instead, return the gasmix by value. This is in preparation of
const-ifying input parameters of a number of core functions, which
will ultimately let the merge() function take const-arguments in
preparation of undo of dive-merging.
On common 64-bit systems gasmix (two "int"s) is the size of a pointer
and can be returned in a register.
On 32-bit systems a pointer to the struct to be filled out will be
passed.
Since get_gasmix() now returns a value, the first invocation is
tested by a NULL-initialized "struct event *". Document this in

This is a first step to interpret bailout events.
1) The event structures have a new attribute: divemode.
Currently interpreted dive modes are OC, CCR, PSCR.
2) When doing fill_pressures(), the calculation is aware
of divemode. When divemode is OC (==bailout), then
the appropriate calculations of gas pressures are done.
3) Two new functions get_next_divemodechange() and
get_divemode_at_time() are created to find divemode
changes in the events linked list and to determine
the dive mode at any point during the dive.
4) fill_pressures gets a small amendment to facilitate
the correct calculations, depending on divemode.
The cases where fill_pressures() is used *outside the planner*
are changed. The result is that, for dives with bailout, the
correct gas pressures are shown on the dive profile. The
deco for bailout dives is not yet correct. This is the
next step.

So the manual gas pressure case keeps showing issues, and in many ways it
really is a fairly complex thing, since it needs interpolation of the
intermediate pressures - possibly over several gas changes.
So you might have beginning and ending pressures for one cylinder, but
then use another cylinder in between.
We've historically got all the code to do this, but the big rewrite for
multiple cylinder pressures didn't get all the details right, and so
here's a few more fixes for the case that was shown by a dive by Robert
Helling. Hopefully we're approaching the old code situation, except now

The core to plot manually entered pressures without any sample data did
the obvious thing: it ended the pressures at the end of the dive as
indicated by the last sample.
However, that obvious thing didn't actually work, because sometimes the
last sample is long long after the dive has actually ended, and we have
no plot_info data for that.
This depends on the dive computer used: most dive computers will not
report samples after the end (even if they may internally remember them
in case the diver just came up to the surface temporarily), but some
definitely do. The OSTC3 is a prime example of that.
Anyway, the code was fragile and wrong - even if passed a time past the
end of the plot_info data, "add_plot_pressure()" should just have
associated that with the last entry instead. Which also allows us to
simplify the whole endtime logic entirely, and just use INT_MAX for it.
Gaetan Bisson's test-case also showed another oddity: we would plot the
gas pressure even for cylinders that had no has use (ie beginning and
ending pressures were the same). That's kind of pointless in so many
ways. So limit the manual pressure population to cylinders that
actually have seen use.

The momentary SAC rate got broken by the multiple ressure handling too,
and always used just the first cylinder.
This uses the new "get_gasmix()" helper to see what you're breathing,
and will do the SAC rate over all the cylinders that contain that gas.
So it should now DTRT even for sidemount diving (assuming you had the
same gas in the sidemount cylinders).
NOTE! We could just do the SAC rate over *all* the gases you have
pressures for, and maybe that's the right thing to do. The ones you are
not breating from shouldn't have their pressure change. But maybe some

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.

This is a very timid start at making us actually use multiple sensors
without the magical special case for just CCR oxygen tracking.
It mainly does:
- turn the "sample->sensor" index into an array of two indexes, to
match the pressures themselves.
- get rid of dive->{oxygen_cylinder_index,diluent_cylinder_index},
since a CCR dive should now simply set the sample->sensor[] indices
correctly instead.
- in a couple of places, start actually looping over the sensors rather
than special-case the O2 case (although often the small "loops" are
just unrolled, since it's just two cases.
but in many cases we still end up only covering the zero sensor case,
because the CCR O2 sensor code coverage was fairly limited.
It's entirely possible (even likely) that this migth break some existing
case: it tries to be a fairly direct ("stupid") translation of the old
code, but unlike the preparatory patch this does actually does change
some semantics.
For example, right now the git loader code assumes that if the git save
data contains a o2pressure entry, it just hardcodes the O2 sensor index
to 1.
In fact, one issue is going to simply be that our file formats do not
have that multiple sensor format, but instead had very clearly encoded
things as being the CCR O2 pressure sensor.
But this is hopefully close to usable, and I will need feedback (and
maybe test cases) from people who have existing CCR dives with pressure
data.

We currently carry two pressures around for all the samples and plot
info, but the second pressure is reserved for CCR dives as the O2
cylinder pressure.
That's kind of annoying when we *could* use it for regular sidemount
dives as the secondary pressure.
So start prepping for that instead: don't make it "pressure" and
"o2pressure", make it just be an array of two pressure values.
NOTE! This is purely mindless prepwork. It literally just does a
search-and-replace, keeping the exact same semantics, so "pressure[1]"
is still just O2 pressure.
But at some future date, we can now start using it for a second sensor
value for sidemount instead.

This combines the display with EADD since this is the same
value with a different unit. And show it for air dives as
well.

This appears to be critical for work of breathing so it might be
worthwhile to compute. So far only in infobox.

Not using lrint(f) when converting double/float to int
creates rounding errors.
This error was detected by TestParse::testParseDM4 failure
on Windows. It was creating rounding inconsistencies
on Linux too, see change in TestDiveDM4.xml.

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.

We have two prefernces determining the deco_mode (BUEHLMANN vs VPMB
vs RECREATIONAL): One for the planner (deco_mode) and one for
displaying dives (display_deco_mode). The former is set in the planner
settings while the latter is set in the preferences.
This patch clears up a confusion which of the two to use by introducing
a helper function that selects the correct variable.

Calculate gfline using the gradient factor that is set by the planner
preferences when in the planner, and by the general prefs when not in the
planner. This is achieved by doing the gradient factor calculation in dive.c,
where buehlmann_config is defined.
Previously, the gfline was calculated using the general preferences gfhigh and
gflow, even when in the planner.

We could create a plot_info data that didn't contain all the time slots
for the events fromt he dive computer, which would terminally confuse
the plotting of the event profile widgets because it couldn't match up
the event with the dive plot data model.
So for example, in DiveEventItem::recalculatePos(), when the code tries
to figure out the spot in the data model, it could fail, and then try to
hide the event (because without the data model information it doesn't
know where it should go). But that hiding would then not match the
logic in DiveEventItem::shouldBeHidden(), and the event would end up
being shown in the upper left-hand corner of the profile after all.
The reason the plot_info data wouldn't contain the time slots is that
the slots are allocated primarily for the sample data, and then the
events would be added in between sample data in populate_plot_entries().
But since we'd only add the event pointer *between* samples, that would
mean that events after the last samples would not get plot-info points
allocated to them.
That issue was exacerbated by how we also truncate uninteresting samples
at the end when some dive computers end up giving a long stream
(possibly several minutes) of "at the surface" events before they
finally turn off logging.
This makes sure that we take the event timestamps into account for the
"maxtime" calculation, and also that we finish populating the plot_info
data with any final event timestamps.
Now all the events will have a matching plot_info entry.
