For dives where divecomputers haven't provided us with a cns, we
calculate our cns accumulated during that dive based on a simple table.
We also check if we did a dive in the prior 12 ours and grab the cns
from it and calculate how much of that still affects us.
[Dirk Hohndel: a couple of small changes: remove unnecessary check of cns
values in the samples of the first dive computer, changed
the way we determine the 'previous dive' and used the end
time of that previous dive for the decay calculation]

This is simplistic & brute force: any function that touches Gtk related
data structures is moved to divelist-gtk.c, everything else stays in
divelist.c.
Header files have been adjusted so that this still compiles and appears to
work. More thought is needed to truly abstract this out, but this seems to
be a good point to commit this change.

Here is a patch that restricts the gases listed in the divelist to those
that are actually used. I seem to have the indentation now under control
but I am not sure about the logic:
1) First gas (with index 0) is always used.
2) If there is a gas switch event, the new gas is also used (determined by
walking the list of dive computers and then the list of events).

A couple of these could clearly cause a crash just like the one fixed by
commit 00865f5a1e1a ("equipment.c: Fix potential buffer overflow in
size_data_funct()").
One would append user input to fixed length buffer without checking.
We were hardcoding the (correct) max path length in macos.c - replaced by
the actual OS constant.
But the vast majority are just extremely generous guesses how long
localized strings could possibly be.
Yes, this commit is likely leaning towards overkill. But we have now been
bitten by buffer overflow crashes twice that were caused by localization,
so I tried to go through all of the code and identify every possible
buffer that could be affected by this.

So far we only allowed setting the max depth.
This changes the layout of the entry widget and makes our helper function
create_date_time_widget return the hbox in which it positions the time
entry. I plan to reuse this later when allowing to edit the duration as
well as the start date and time under certain circumstances.

This creates a helper function called "gas_volume()" that takes the
cylinder and a particular pressure, and returns the estimated volume of
the gas at surface pressure, including proper approximation of the
incompressibility of gas.
It very much is an approximation, but it's closer to reality than
assuming a pure ideal gas. See for example compressibility at

The code was written to get the SAC rate correct, but we probably do
want to have the duration and mean depth of the dive always be shown for
the non-surface-time.
So move the code from the sac-rate calculation to the generic dive fixup
part. This makes the dive list and statistics all show the duration as
the under-water duration, which is not necessarily the same as
"difference between beginning and end of dive".

This assumes that you are not breathing your cylinders while at the
surface, which may or may not be correct, but is usually the right
thing. Regardless, we're better off giving a conservative (higher) SAC
rate estimate for a diver that breathes his cylinder at the surface too
than giving an artificially low one because the diver ended up using his
snorkel and we didn't take that into account.
NOTE! This basically calculates a better duration and average depth than
the ones we end up showing in the dive list. Maybe we should actually
show this "no-surface-time" duration and average depth instead of the
ones we do show?
That's a separate question, though.
Added a test-case for the surface case to the sac-test.xml dives.

We even documented that we did SAC in bar*l/min, but the "S" in SAC
stands for "Surface". So we should normalize SAC rate to surface
pressure, not one bar.
It's a tiny 1% difference, and doesn't actually matter in practice, but
it's noticeable when you want to explicitly test for SAC-rate by
creating a test-dive that averages exactly 10m. Suddenly you don't get
the round numbers you expect.
[ Side note: 10m is not _exactly_ one extra atmosphere according to our
calculations, but it's darn close in sea water: the standard salinity
of 1.03 kg/l together with the standard acceleration of 9.81m/s^2
gives an additional pressure of 1.01 bar, which is within a fraction
of a percent of one ATM.
Of course, divers have likely chosen that value exactly for the math
to come out that way, since the true average salinity of seawater is
actually slightly lower ]
So here's a few test-dives, along with the SAC rate fixup to make them
look right.
(There's also a one-liner to dive.c that makes the duration come out
right if the last sample has a non-zero depth, and the previous sample
did not: one of my original test-dives did the "average 10m depth" by
starting at 0 and ending at 20m, and dive.c got a tiny bit confused
about that ;)
[ The rationale for me testing our SAC rate calculations in the first
place was that on snorkkeli.net user "Poltsi" reported that our SAC rate
calculations differ from the ones that Suunto DM4 reports. So I wanted
to verify that we did things right.
Note that Poltsi reported differences larger than the difference of
BAR/ATM, so this is not the cause. I'll continue to look at this. ]

Each time subsurface starts there is supposedly no sorting order
(or divelist column) specified by the UI, yet the actual column is '#'
(or dive number column), since its the *only* column which allows
trips to be visible. If the user selects a different sorting order
then he has no idea which column was the one who had the trips visible.
"Where did all those 'trip' things go?"
This can be a bit confusing...
Lets provide indication by calling gtk_tree_view_column_set_sort_indicator().
Also call gtk_tree_view_column_set_sort_order() to specify a descending
order.

With commit 800b0482f39e ("When switching sort order, scroll the dive
list to the current dive") we introduced an unwanted new behavior. When
changing sort columns we could lose all selections except for the main
"selected_dive". This was caused by the call to gtk_tree_view_set_cursor
on the selected_dive which unselected all other dives.
As a side-effect this also fixed another bug that was introduced by the
same change: shift-cursor-up and -down now works again to select multiple
dives with the keyboard.
But fixing that bug unearthed a different issue. Our code that restored
the selection state of the tree model oddly decided to mark a divetrip as
selected if its first child was selected. The bug above masked that by
immediately unselecting the trip again, but now that this was fixed the
problem was immediately obvious: we would start with both the first trip
and the first dive in that trip selected (well, since we are in reverse
order it's actually the chronologically last trip and last dive...).
Instead we now use the remembered state of the trip to determine whether
it should be expanded or selected.

The 'remember_tree_state()' thing is meant to remember if a dive trip is
expanded or not, but it missed the "or not" part. IOW, it never cleared
the expanded flag, it only ever set it.
As a result, if you were doing multiple operations on the divelist tree
(testing all the recent gtk-model removal, for example) the dive trips
would end up expanding more and more, even if you collapsed things by
hand in between operations.

We used to look up dive trips by their date, but these days we always
create a dynamic index for a dive trip when we insert it into the
divelist model, so we can use that to unambiguously match up dive trips
with the dive model entries.
That means that we don't get confused if we have two trips with the
exact same time, which happens when you load all the test-dives, for
example.

This does a final pass after all the selection logic, and notices if we
have dive trips that are selected, but that have no dives in them
selected. In that case, we assume that the user wanted to select all
dives in that trip.
NOTE! This still allows a range selection that selects the dive trip
entry and a few dives under the trip. If a trip has any dives selected
in it, we leave that manual selection alone. So this new logic really
only triggers on the case where somebody selected *just* the trip.
Note: unselecting the trip still leaves the dives under it selected,
because having a dive trip that isn't selected have all the dives under
it be selected is normal, and we can't recognize that as some kind of
special event.

This adds watertemp and airtemp to the dive, populates them in fixup and
uses them elsewhere in the code.
WARNING: as a sideeffect we now edit the airtemp in the dive, but we never
display this in the DIve Info notebook (as that always displays the data
from the specific selected divecomputer). This is likely to cause
confusion. It's consistent behavior, but... odd. This brings back the
desire to have a view of "best data available" for a dive, in addition to
the "per divecomputer" view. This would also allow us to consolidate the
different pressure graphs we may be getting from different divecomputers
(consider the case where you dive with multiple air integrated computers
that are connected to different tanks - now we could have one profile with
all the correct tank pressure plots overlayed - and the best available (or
edited) data in the corresponding Dive Info notebook.
This commit also fixes a few remaining accesses to the first divecomputer
that fell through the cracks earlier and does a couple of other related

When starting on this quest to stop using the first divecomputer instead
of data for the whole dive in commit eb73b5a528c8 ("Duration of a dive is
the maximum duration from all divecomputers") I introduced an accessor
function that calculates the dive duration on the fly as the maximum of
the durations in the divecomputers.
Since then Linus and I have added quite a few of the variables back to the
dive data structure and it makes perfect sense to do the same thing for
the duration as well and simply do the calculation once during fixup.
This commit also replaces accesses to the first divecomputer in
likely_same_dive to use the maxdepth and meandepth of the dive (those two
slipped through the cracks in the previous commits, it seems).

In commit b6c9301e5847 ("Move more dive computer filled data to the

dive computers to be per-divecomputer data structures.
This patch re-creates some of those fields back in the "struct dive",
but now the fields are initialized to be a reasonable average from the
dive computer data. We already did some of this for the temperature
min/max fields for the statistics, so this just continues that trend.
The goal is to make it easy to look at "dive values" without having to
iterate over dive computers every time you do. Just do it once in
"fixup_dive()" instead.

There are two ways to look at surface pressure. One is to say "what was
the surface pressure during that dive?" - in that case we now return an
average over the pressure reported by the different divecomputers (or the
standard 1013mbar if none reported any).
Or you want to do specific calculations for a specific divecomputer - in
which case we access only the pressure reported by THAT divecomputer, if
present (and fall back to the previous case, otherwise).
We still have lots of places in Subsurface that only act on the first
divecomputer. As a side effect of this change we now make this more
obvious as we in those cases pass a pointer to the first divecomputer
explicitly to the calculations.
Either way, this commit should prevent us from ever mistakenly basing our
calculations on a surface pressure of 0 (which is the initial bug in
deco.c that triggered all this).
Similar changes need to be made for other elements that we currently only
use from the first divecomputer, i.e., salinity.

This no longer abuses the dive merging code (which would leave stray
"dives" behind if a gps fix couldn't be merged with any of the dives) and
instead parses the gps fixes into a second table and then walks that table
and tries to find matching dives.
The code tries to be reasonably smart about this. If we have
auto-generated GPS fixes at regular intervals, we look for a fix that is
during a dive (that's likely when the boat where the phone is staying dry
is more or less above the diver having fun). And if we have named entries
(so the user typed in a location name) we try to match them in order to
the dives that happened "that day" (where "that day" is about 6h before
and after the timestamp of the gps fix).
This commit also renames dive_has_location() to dive_has_gps_location() as
the difference between if(!dive->location) and if(dives_has_location) is a
bit too subtle...
