There were some small leaks before here, related to gtk_tree_iter_copy(),
but there is another one in select_next_dive():
nextiter = gtk_tree_iter_copy(iter);
This now requires a SJ near the epilog where we do the memory cleanup.
Lets call this similar label consistently "free_iter" between
select_prev_dive and select_next_dive.

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.

When the user changes the dive list sorting order via clicking
on different column titles, using gtk_widget_grab_focus() gives
keyboard focus back to the list itself (not staying on the column titles),
which gives a hint that the list itself has focus index of 0 and is
reset each time the widget receives this type of "initial" focus.

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.

Instead, just keep track of the expanded state of trips as we get the
gtk callbacks for the state changes (which we need to track anyway for
the selection logic), and automatically restore the state whenever we
re-create the divelist.

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.

.. use our own data structures instead, and regenerate the gtk ones

This simplifies the code enormously, and also makes it much more

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
cleanups.

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
divecomputer structure") we moved the fields that get filled in by 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.

Sure, there may be other selected dives, but we have one primary

With the changes to the selection logic the selected_dive variable didn't
get updated at the end of planning a dive. With an empty dive list that
could cause selected_dive to be -1 which would subsequently cause a

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...

In commit 304526850c91 ("Don't deselect all dives on all selection
"change" events") the handling of "selected_dive" is incorrect. We ended
up with non-sensical values for the selected dive, including dives that
Gtk didn't think were selected.
This commit tries to be smart about what to do when the dive that we
currently consider selected is unselected (we have this weird notion of
many dives being selected, but one of them is shown in the profile and
that is the "selected_dive"). As long as there are others selected, we
pick one of them (first walking to earlier dives and if there are none
that are selected, looking for a later dive) as the new selected dive.
This appears to give us a rather intuitive behavior when playing with
multiple selected dives.

gtk sends the selection change events all the time, for pretty much any
"divelist changed - so selection changed". The expansion of a trip, the
switch to a new model, yadda yadda. But we actually want selections to
be sticky across these events, so we can't just forget all of our old
selection state and repopulate it.
So we re-introduce the "am I allowed to change this row" callback, which
we used to use to create a list of every actual selection that was
changed. But instead of remembering the list (and having the stale
entries issue with that remembered list that caused problems), we now
just use that as a "that *particular* selection cleared" event.
So this callback works as the "which part of the visible, currently
selected state got cleared" notifier, and handles unselection.
Then, when the selection is over, we use the new model of "let's just
traverse the list of things gtk thinks are selected" and use that to
handle new selections in the visible state that gtk actually tracks
well. So that logic handles the new selections.
This way, dives that aren't visible to gtk don't ever get modified: gtk
won't ask about them being selected or not, and gtk won't track them in
its selection logic, so with this model their state never changes for
us.
gtk selections are annoying. They are simple for the case gtk knows
about (ie they are *visually* selected in the GUI), but since we very
much want to track selection across events that change the visual state,
we need to have this insane "impedance match".

We used to generate a list of possibly changed selections using the gtk
tree selection "selection function".
But that's actually meant to just tell gtk whether an entry can be
selected or not, and our list of possibly changed entries ended up being
stale if the selection change was due to a list entry removal, for
example.
So rip out the old model entirely, and instead just walk the whole
selection that gtk gives us on a selection "change" event. We throw all
our old selections away when this happens, and just rebuild it all.
This should fix the occasional internal gtklib-quartz assertion that
Henrik is seeing. And it actually simplifies the code too.

Add a sample at time 0 to allow for a pO2 from the start of the dive.
Remember the last pO2 so it doesn't have to be repeated (and the right
thing happens for the planned part of the dive).
This still doesn't allow us to change the setpoint at a certain depth
(which would be analogous to being able to switch to a certain gas at a
certain depth in OC plans), but with this commit it's already usable.
This commit also fixes a couple of small bugs in commit b8ee3de870fa
("Dive planning for closed circuit rebreather") where a pO2 of 1.1 was
hardcoded in one place, throwing off all plan calculations and integer
math was used to calculate a floating point value (leading to most pO2

The 'preexisting' value is used for downloading dives: we want to add
new dives but, but then compare those new dives against the
preexisting ones before we start sorting things and possibly merging
them.
However, the value was only updated sporadically, resulting in it
having stale information in it. Which would cause problems
particularly if you deleted dives, so that the preexisting value would
point past the actual existing values!
So just update it unconditionally in dive_list_update_dives(), which
anything that changes the dive list is supposed to call in order to
display the changes anyway.
Also, just for safety, when removing a dive, put NULL in the last dive
table location. Nobody should ever access past the end anyway (this
is enforced by 'get_dive()') but there are places that access the dive
list table directly, and the libdivecomputer download was one of
those. No reason to leave stale dive pointers possibly around for
uses like that.

This replaces the really lame "italics text" from commit abe810ca1a29
("Mark locations that have GPS location data attached") with a marginally
less lame GPS icon.There's a reason why I am not making a living as
graphics artist. But I think this is a huge step forward from what we had
before...
The satellite.svg file is very loosely based on a different icon that I
found as public domain here http://www.clker.com/clipart-30400.html.
From that I created the PNG and then that was converted into the
GdkPixdata via gdk-pixbuf-csource; a rule for that was added to
the Makefile but commented out as I don't know if this tool will always be
available in the path. Having this icon included in the sources avoids
locating yet another icon file.
Better icons are certainly welcome!

This is rather lame - we simply turn the location text into italics for those
dives where we have GPS location data. Underlining might be more natural, but
Gtk plays games with the underline attribute if the mouse hovers over text.
Ideally I would have prefered a little GPS logo next to the location text - but
I couldn't figure out how to do that without writing my own cell renderer which

Of course, having some way to visually see whether we have a GPS
