This uses a bunch of default values that we eventually need to get from
the UI, but it's a first step towards a working dive planner.
This exhibits some graphical artifacts when running, but other than that
appears to be mostly correct.
Things go far worse if I enable the changing of the scale once the deco
makes the dive longer than the displayed time window. Things quickly
spiral out of control.

I expanded the DiveHandler to include the actual time / depth of each
node on the graph - this way things will stay consistent if we need to
rescale the graph.
One thing that this makes obvious is that the whole design for the
planner so far assumes metric data. We need to make sure this works well
with feet instead of meters as well (and that it uses the information in
the units settings).
With this change we actually create a dive based on the plan input and
add the deco stops (if needed) to it - but we don't do anything with the
results of those calculations, yet.

After the 3.1 release it is time to shift the focus on the Qt effort - and
the best way to do this is to merge the changes in the Qt branch into
master.
Linus was extremely nice and did a merge for me. I decided to do my own
merge instead (which by accident actually based on a different version of
the Qt branch) and then used his merge to double check what I was doing.
I resolved a few things differently but overall what we did was very much
the same (and I say this with pride since Linus is a professional git
merger)
Here's his merge commit message:
This is a rough and tumble merge of the Qt branch into 'master',
trying to sort out the conflicts as best as I could.
There were two major kinds of conflicts:
- the Makefile changes, in particular the split of the single
Makefile into Rules.mk and Configure.mk, along with the obvious Qt
build changes themselves.
Those changes conflicted with some of the updates done in mainline
wrt "release" targets and some helper macros ($(NAME) etc).
Resolved by largely taking the Qt branch versions, and then editing
in the most obvious parts of the Makefile updates from mainline.
NOTE! The script/get_version shell script was made to just fail
silently on not finding a git repository, which avoided having to
take some particularly ugly Makefile changes.
- Various random updates in mainline to support things like dive tags.
The conflicts were mainly to the gtk GUI parts, which obviously
looked different afterwards. I fixed things up to look like the
newer code, but since the gtk files themselves are actually dead in
the Qt branch, this is largely irrelevant.
NOTE! This does *NOT* introduce the equivalent Qt functionality.
The fields are there in the code now, but there's no Qt UI for the
whole dive tag stuff etc.
This seems to compile for me (although I have to force
"QMAKE=qmake-qt4" on f19), and results in a Linux binary that seems to
work, but it is otherwise largely untested.

Testing the Planner in Subsurface on a Windows XP SP3 installation,
shows corrupted UTF-8 strings in the case of Cyrillic locales, but
possibly others as well. Instead limited to the Planner, this affects
the entire application.
After some examination it appears that <ctype>'s isspace() in MSVC
on the tested version of Windows is broken for some UTF-8 characters,
after enabling the user locale using: setlocale(LC_ALL, "");
For example, characters such as the Cyrillic capital "BE" are defined as:
0xD091, where isspace() for the first byte returns 0x08, which is the
bytemask for C1_SPACE and the character is treated as space.
After a byte is treated as space, it is usually discarded from a UTF-8
character/string, where if only one byte left, corrupting the entire
string.
In Subsurface, usages of string trimming are present in multiple
locations, so to make this work try to use GLib's g_ascii_isspace(),
which is a locale agnostic version of isspace().
Affected versions of Windows could be everything up to XP SP3,
but not apparently Vista.

The existing code has an embarrassing error in its logic. It picked the
last dive in the table and made sure that the relative start time was
either N minutes after 'now' or N minutes after the last dive ends,
whichever is later.
But once the planned dive has been added to the dive list (so once we have
a first depth and time entry, that last dive now is the planned dive. And
every time focus left the start time field the start time would be
recalculated relative to the end of the dive we are currently planning.
With this patch we instead simply remember the number of the last dive
just as we create the dive plan and use that to look up the end time of
previous dive. I could have just stored that end time but I figured maybe
there could be other reasons to go back to the last dive before the
planned dive, so this seemed cleaner.

Printf is not a way to issue warnings and errors. This is a very late

This also adds one artificial limit and two warnings:
a) no dives deeper than 400m
b) warning of potentially very long calculation times for dives longer
than 3h (180min) before the ascent and dives deeper than 150m

Stuff like this is just BS.
Don't do it. You already fixed the bug with matching gas change events,

It's not even percent. It's still permille, just rounded. So it's a
nonsensical number and a misleading name. Just delete it as the abortion

Two separate bugs.
a) Air cylinders were created with o2=209 and no other value set.
sanitize_gasmix() turned that into o2=0 which meant that this cylinder was
now identified as "nodata", i.e., unset.
We now set a fake cylinder name to deal with that issue.
b) the gaschange event is inherited from libdivecomputer and therefore
only supports 1 percent granularity for o2 and h2. Since we didn't round
when assigning the value we ended up with air being stored as o2=20 he=0
which of course then didn't match air anymore (which we have defined as
208 <= o2 <= 210).
We now use o2=210 for air in the planner and carefully round the permille
values whenever we convert into percent - and compare gases with percent
granularity as well.
A better fix for b) would be to change the Subsurface event to not simply
copy the libdivecomputer behavior and use percent granularity but support
permille instead. But this closely before the 3.0 release that seemed like
a far too invasive change to make - the changes to the planner should have
no impact outside the planner module.

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.

iterate over dive computers every time you do. Just do it once in

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.

Add a sample at time 0 to allow for a pO2 from the start of the dive.

The planner interactively responds to changes to the GFlow and GFhigh in
the dialog and calculates an appropriate profile. If there is a previous
dive within the 48 hours prior to this dive then its saturation is
correctly taken into account if the gradient factors are changed - so if
they are aggressively lowered it is possible to start the dive with
already an existing ceiling (simply increase the surface interval to 'fix'
that).
Once the plan is accepted the GF values are reset to the current
preferences. This can cause the ceiling in the plot to change and the deco
stops to no longer match the ceiling - but that's a logical consequence of
the ability to change a temporary copy of GFlow/GFhigh during the planning
process and not the actual preferences (which would be counter intuitive,
I think).
