The old implementation was broken in several ways.
For one thing the GF values are percentages, so they should normally be
0 < GF < 1 (well, some crazy people like to go above that).
With this most of the Bühlmann config constants were wrong.
Furthermore, after we adjust the pressure tolerance based on the gradient
factors, we need to convert this back into a depth (instead of passing
back the unmodified depth - oops).
Finally, this commit adds closed circuit support to the deco calculations.
Major progress and much more useful at this stage.

This seems like a strange way to capture the FOCUS_CHANGE event, but
manually trying to register a callback for it fails. Yet registering a
callback for every event and then filtering for FOCUS_CHANGE in the
callback works. Go figure.
But with this commit you can actually change the GF settings in the
preferences dialog and once you tab out of the entry field the change gets
immediately applied - nice to play with the effects of changing GF values.

There were some minor problems when moving the selection
cursor around:
1) If the selection was larger than 1, it was possible
for the selection to get "stuck" in the middle of the list.
This patch approaches this by always calling
gtk_tree_selection_unselect_all() before
gtk_tree_selection_select_iter(), or simply always making
sure we have one selected iterator when navigating with the keys.
2) When there was a single top level dive before the first trip
it wasn't possible to navigate trough the child dives of said
trip in both directions.
The patch attempts to fix this by having the hunks/checks:
if (idx < 0) {
(idx is of a trip) performed regardless of other conditions.
*** Note: testing was done by importing all test*.xml
dives with auto-group on.
[Dirk Hohndel: adjusted the patch to also fix on_key_press to only grab
the key if no modifier key is pressed; otherwise this
breaks shift-cursor-keys for selecting multiple dives.]

If we print out the pressure difference (because we do not have a cylinder
size), we didn't initialize the precision. We should print out pressures
without decimals.
The attached patch fixes that, and also avoids a NULL pointer printout
(which on Linux will just print out "(null)") if there is no cylinder
type descriptor string. It also cleans things up a bit and uses the

This also initializes the N2 tissue saturations to correct numbers
(setting them to zero was clearly silly).
With this commit we walk back in the dive_table until we find a surface
intervall that's longer than 48h. Or a dive that comes after the last one
we looked at; that would indicate that this is a divelist that contains
dives from multiple divers or dives that for other reasons are not
ordered. In a sane environment one would assume that the dives that need
to be taken into account when doing deco calculations are organized as one
trip in the XML file and so this logic should work.
One major downside of the current implementation is that we recalculate
everything whenever the plot_info is recreated - which happens quite
frequently, for example when resizing the window or even when we go into
loup mode. While this isn't all that compute intensive, this is an utter
waste and we should at least cache the saturation inherited from previous
dives (and clear that number when the selected dive changes). We don't
want to cache all of it as the recreation of the plot_info may be
triggered by the user changing equipment (and most importantly, gasmix)
information. In that case the deco data for this dive does indeed have to
be recreated. But without changing the current dive the saturation after
the last surface intervall should stay the same.

In commit 96db56f89c ("Allow overlapping (and disjoint) dive trips")
I allowed dives to be part of arbitrary dive trips regardless of date,
which meant that the divelist tree model code needed to find the right
parent for a dive as it was inserted.
That code stupidly assumed that the top level of the dive list tree
containted *only* trips, which is not at all the case. It happens to
be true if you group all your dives into divetrips (the common case
for autogroup=1, which real users do tend to have), but now that Dirk
made the autogrouping be a per-xml-file setting, it became much easier
to trigger the "mixed trips and non-trip dives" case, and that showed
the stupid bug with the test dives.
So instead of just blindly iterating to the 'n'th entry, search for
the actual entry that is the dive trip we want to associate a dive
with.

Having two spots to toggle autogroup had always been a clear sign of

This finally gets rid of that disaster and drops the autogroup setting
from the preferences and makes it instead a per file property. When you
save a file, it saves the state of the autogroup toggle. This seems much
more useful - you may have files where you want to create trips by

This commit steals the cursor up and down keys away from gtk so regardless
where gtk thinks the focus may be, we can still use the keys to change
between dives.
In the current UI design where all editing happens in separate windows
this works as expected, as we only grab the keys for the main window. If
we manage to re-enable in-place editing then we need to make sure that
this doesn't cause problems (as gtk uses up/down for the ability to change
drop down selections in combo boxes or values in spin buttons. So we must
make sure that we stop stealing these keys once we start editing something
(in which case simply switching to the next/prev dive wouldn't be a good
thing, anyway).

This clarifies/changes the meaning of our "cylinderindex" entry in our
samples. It has been rather confused, because different dive computers
have done things differently, and the naming really hasn't helped.
There are two totally different - and independent - cylinder "indexes":
- the pressure sensor index, which indicates which cylinder the sensor
data is from.
- the "active cylinder" index, which indicates which cylinder we actually
breathe from.
These two values really are totally independent, and have nothing
what-so-ever to do with each other. The sensor index may well be fixed:
many dive computers only support a single pressure sensor (whether
wireless or wired), and the sensor index is thus always zero.
Other dive computers may support multiple pressure sensors, and the gas
switch event may - or may not - indicate that the sensor changed too. A
dive computer might give the sensor data for *all* cylinders it can read,
regardless of which one is the one we're actively breathing. In fact, some
dive computers might give sensor data for not just *your* cylinder, but
your buddies.
This patch renames "cylinderindex" in the samples as "sensor", making it
quite clear that it's about which sensor index the pressure data in the
sample is about.
The way we figure out which is the currently active gas is with an
explicit has change event. If a computer (like the Uemis Zurich) joins the
two concepts together, then a sensor change should also create a gas
switch event. This patch also changes the Uemis importer to do that.
Finally, it should be noted that the plot info works totally separately
from the sample data, and is about what we actually *display*, not about
the sample pressures etc. In the plot info, the "cylinderindex" does in
fact mean the currently active cylinder, and while it is initially set to
match the sensor information from the samples, we then walk the gas change
events and fix it up - and if the active cylinder differs from the sensor
cylinder, we clear the sensor data.

We used to have the rule that a dive trip has to have all dives in it in
sequential order, even though our XML file really is much more flexible,
and allows arbitrary nesting of dives within a dive trip.
Put another way, the old model had fairly inflexible rules:
- the dive array is sorted by time
- a dive trip is always a contiguous slice of this sorted array
which makes perfect sense when you think of the dive and trip list as a
physical activity by one person, but leads to various very subtle issues
in the general case when there are no guarantees that the user then uses
subsurface that way.
In particular, if you load the XML files of two divers that have
overlapping dive trips, the end result is incredibly messy, and does not
conform to the above model at all.
There's two ways to enforce such conformance:
- disallow that kind of behavior entirely.
This is actually hard. Our XML files aren't date-based, they are
based on XML nesting rules, and even a single XML file can have
nesting that violates the date ordering. With multiple XML files,
it's trivial to do in practice, and while we could just fail at
loading, the failure would have to be a hard failure that leaves the
user no way to use the data at all.
- try to "fix it up" by sorting, splitting, and combining dive trips
automatically.
Dirk had a patch to do this, but it really does destroy the actual
dive data: if you load both mine and Dirk's dive trips, you ended up
with a result that followed the above two technical rules, but that
didn't actually make any *sense*.
So this patch doesn't try to enforce the rules, and instead just changes
them to be more generic:
- the dive array is still sorted by dive time
- a dive trip is just an arbitrary collection of dives.
The relaxed rules means that mixing dives and dive trips for two people
is trivial, and we can easily handle any XML file. The dive trip is
defined by the XML nesting level, and is totally independent of any
date-based sorting.
It does require a few things:
- when we save our dive data, we have to do it hierarchically by dive
trip, not just by walking the dive array linearly.
- similarly, when we create the dive tree model, we can't just blindly
walk the array of dives one by one, we have to look up the correct
trip (parent)
- when we try to merge two dives that are adjacent (by date sorting),
we can't do it if they are in different trips.
but apart from that, nothing else really changes.
NOTE! Despite the new relaxed model, creating totally disjoing dive
trips is not all that easy (nor is there any *reason* for it to be
easty). Our GUI interfaces still are "add dive to trip above" etc, and
the automatic adding of dives to dive trips is obviously still based on
date.
So this does not really change the expected normal usage, the relaxed
data structure rules just mean that we don't need to worry about the odd
cases as much, because we can just let them be.

This commit makes deco handling in Subsurface more compatible with the way
libdivecomputer creates the data. Previously we assumed that having a
stopdepth or stoptime and no ndl meant that we were in deco. But
libdivecomputer supports many dive computers that provide the deco state
of the diver but with no information about the next stop or the time
needed there. In order to be able to model this in Subsurface this adds an
in_deco flag to the samples. This is only stored to the XML file when it
changes so it doesn't add much overhead but will allow us to display some
deco information on dive computers like the Atomic Aquatics Cobalt or many
of the Suuntos (among others).
The commit also removes the old event based deco code that was commented
out already. And fixes the code so that the deco / ndl information is

We used to enable dive trips whenever we sorted by date, which can be
a bit annoying. Sometimes you really just want to sort all your dives
by date, without necessarily seeing the trip data.
So this changes the default sort to be the "dive number" table, and
then does *not* actually sort by the dive number, but instead enables
the trips, and then sorts the result by date. So the "dive number"
column - which used to be non-sortable - becomes semantically
equivalent to the old date column sorting.
And now sorting by date makes it act like sorting by depth or any
other attribute - we hide the dive trip tree, and just show the plain
list of dives (sorted by date, obviously).

When downloading from a dive computer, we fall back on matching the

well synchronized, they might actually have the exact same date,
despite the fact that we do want to download both dive computers. We
do check the dive start to the exact second, so this sounds unlikely,
but with dive computers rounding time to the next minute etc, it's not
as unlikely as you'd think. Dirk hit it.

2) dive.c:merge_text(), now always makes a copy in memory for the returned

The reason for the above two changes is that when (say) importing the same

but mapped pointers can go out of scope.
main.c:report_dives() calls try_to_merge() and if succeeds the two dives

itself, which precedes, copies of the merged texts are made (with merge_text()),
