Therefore replace the enum by a simple boolean.
Currently, there is no way of unsetting the notrip flag. But this

The distinction between ASSIGNED_TRIP and IN_TRIP was used to
prefer non-autogenerated trips on merging of dives. But owing
to bit rot this seem to have worked only partially anyway:
The IN_TRIP field was set in create_and_hookup_trip_from_dive()
and immediately overwritten in add_dive_to_trip() called
in the next line.
Instead, use the trip->autogen flag to check for priority and
remove the ASSIGNED_TRIP flag alltogether.

To make sorting more controlled, move all sorting functions into
the core. For this, introduce a "dive_or_trip" structure, which
represents a top-level item. Adapt the DiveTripModel accordingly.
There are now three sorting functions:
1) dive_less_than
2) trip_less_than
3) dive_or_trip_less_than
These should be used by all sorting code. By moving them to a
single place, the mess can hopefully be cleaned up.

Up to now, dives were added to the global dive table with

are added at a specific position or the sort-criterion given

There were two versions of the insert_trip() function: one
would merge trips if a trip with the same date already existed,
the other wouldn't. The latter was introduced with the dive-list
undo work.
The problem is that the "date" of a trip (i.e. the first dive)
seems ill-defined as this is a volatile value. Moreover in
the context of making dive-import undoable this is a very
dangerous notion, as the caller needs control over when the dives
are added to a trip.
Therefore, unify these two functions and never merge trips.
The decision on merging dives now has to made by the caller.
This will be implemented in a future commit.

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.

insert_trip() adds a trip to the backend, but merges trips if
there exists a trip with the same date. This is a disaster
for the MergeTrips command, because this command adds a new
trip and removes the previous two. Of course if the added trip
is merged, this cannot work.
Therefore, add an insert_trip_dont_merge() function, which
adds the trip, but doesn't merge.

first.

large parts the same thing as undo/redo of dive deletion (just the

The original undo-code was fundamentally broken. Not only did it leak
resources (copied trips were never freed), it also kept references
to trips or dives that could be changed by other commands. Thus,
anything more than a single undo could lead to crashes.
Two ways of fixing this were considered
1) Don't store pointers, but unique dive-ids and trip-ids.
Whereas such unique ids exist for dives, they would have to be
implemented for trips.
2) Don't free objects in the backend.
Instead, take ownership of deleted objects in the undo-object.
Thus, all references in previous undo-objects are guaranteed to
still exist (unless the objects are deleted elsewhere).
After some contemplation, the second method was chosen, because
it is significantly less intrusive. While touching the undo-objects,
clearly separate backend from ui-code, such that they can ultimately
be reused for mobile.
Note that if other parts of the code delete dives, crashes can still
be provoked. Notable examples are split/merge dives. These will have
to be fixed later. Nevertheless, the new code is a significant
improvement over the old state.
While touching the code, implement proper translation string based
on Qt's plural-feature (using %n).

Instead, read the timestamps only once in the constructor of

Commit f5b11daffd changed gasmix

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

Currently, get_gasmix_from_event() and get_gasmix() return pointers

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

dive_getUniqID() is used to create unique dive ids, which are

alloc_dive(): called the function on a zeroed dive struct.
fixup_dive(): called the function only if the dive had a 0 id.
MainWindow::setupForAddAndPlan(): called the function on a zeroed dive

This provides for reading of divemode change events from dive logs

event->name = "modechange"
event->value = integer corresponding to enum dive_comp_type (dive.c),
reflecting the type of divemode change (OC, CCR, PSCR, etc).
In the dive log file, the event value is written as a string that
corresponds to each of the enum values, e.g.
<event name='modechange' divemode='OC' />
This xml is also read from the dive log file and translated to an

This is the second step for implementing bailout. The indirect

1) The parameters to add_segment() are changed to take a

2) Call to add_segment() in profile.c and in divelist.c are
adapted. In divelist.c some calls to add_segment were left
using dc-> divemode instead of possible bailout. This appears
tp be the most appropriate route.
3) The functions get_divemode_from_time() and get_next_divemodechange()

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.

1) In dive.h, create a new dc attribute dc->last_manual_time
with data type of duration_t.
2) In diveplanner.c, ensure that the last manually-entered
dive planner point is saved in dc->last_manual_time.
3) In save-xml.c, create a new XML attribute for the <divecomputer>
element, named last-manual-time. For dive plans, the element would
now look like:
<divecomputer model='planned dive' last-manual-time='31:17 min'>
4) In parse-xml.c, insert code that recognises the last-manual-time
XML attribute, reads the time value and assigns this time to
dc->last_manual_time.
5) In diveplannermodel.cpp, method DiveplannerPointModel::loadfromdive,
insert code that sets the appropriate boolean value to dp->entered
by comparing newtime (i.e. time of dp) with dc->last_manual_time.
6) Diveplannermodel.cpp also accepts profile data from normal dives in
the dive log, whether hand-entered or loaded from dive computer. It
looks like the reduction of dive points for dives with >100 points
continues to work ok.
The result is that when a dive plan is saved with manually entered
points up to e.g. 10 minutes into the dive, it can be re-opened for edit
in the dive planner and the planner re-creates the plan with manually
entered points up to 10 minutes. The rest of the points are "soft"
points, shaped by the deco calculations of the planner.

In general, the C++-side of the preferences code consistently uses

This patch attempts to make the code more consistent by turning
these into bools as well.
Tests showed that writing as short and reading as bool is handled
gracefully by the Qt variant code. Therefore, an upgrade should not
cause user-visible changes to their settings.

I'm sure this bug has heen here forever, but the CNS clock is

do not care about this value.
However, doing long decompression dives, the value can easily
grow over 100%, and a lot further. For example, the OSTC computers
use 2 bytes to store the CNS value in the profile data, and I
have multiple dives in my logbook going way over 255%.

current_dc is a macro that determines the dive computer
based on the current dive number. When the planner is started
from an emtpy dive list, the dive number ends up being -1 and
that doesn't produce a valid dive computer. Use the divecomputer
of the displayed_dive instead. This is done via a macro that
can also be used in two other places. Without this patch, the
planner crashed when called on an empty dive list.

When changing the date/time of a dive in the planner the dive may end
up in a totaly new position in respect to date/time of other dives in
dive list table. It can be moved to the past or the future before or after
other existing dives. It also could overlap with an existing dive.
This change enables identification of a new "virtual" dive list position
and based on this starts looking for previous dives.
Then it (as before the change) does init the deco calculation with any
applicable previous dive and surface interval.
If some of these applicable dives overlap it returns a neg. surface time
which is then used in the planner notes to prohibit display of results.

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
people add their drysuit argon gas to the gas list?
So this may need more work, but it's a step in the right direction.

We have a few places that used to get the gasmix by looking at the
sensor index in the plot data, which really doesn't work any more.
To make it easier for those users to convert to the new world order,
this adds a "get_gasmix()" function. The gasmix function takes as its
argument the dive, the dive computer, and the time.
In addition, for good performance (to avoid looping over the event list
over and over and over again) it maintains a pointer to the next gas
switch event, and the previous gas. Those need to be initialized to
NULL by the caller, so the standard use-case pattern basically looks
like this:
struct gasmix *gasmix = NULL;
struct event *ev = NULL;
loop over samples or plot events in increasing time order: {
...
gasmix = get_gasmix(dive, dc, time, &ev, gasmix);
...
}
and then you can see what the currently breathing gas is at that time.
If for some reason you need to walk backwards in time, you can just pass
in a NULL gasmix again, which will reset the event iterator (at the cost
of now having to walk all the events again).

This tries to sanely handle the case of a dive computer reporting
multiple cylinder pressures concurrently.
NOTE! There are various "interesting" situations that this whole issue
brings up:
- some dive computers may report more cylinder pressures than we have
slots for.
Currently we will drop such pressures on the floor if they come for
the same sample, but if they end up being spread across multiple
samples we will end up re-using the slots with different sensor
indexes.
That kind of slot re-use may or may not end up confusing other
subsurface logic - for example, make things believe there was a
cylidner change event.
- some dive computers might send only one sample at a time, but switch
*which* sample they send on a gas switch event. If they also report
the correct sensor number, we'll now start reporting that pressure in
the second slot.
This should all be fine, and is the RightThing(tm) to do, but is
different from what we used to do when we only ever used a single
slot.
- When people actually use multiple sensors, our old save format will
start to need fixing. Right now our save format comes from the CCR
model where the second sensor was always the Oxygen sensor.
We save that pressure fine (except we save it as "o2pressure" - just
an odd historical naming artifact), but we do *not* save the actual
sensor index, because in our traditional format that was always
implicit in the data ("it's the oxygen cylinder").
so while this code hopefully makes our libdivecomputer download do the
right thing, there *will* be further fallout from having multiple
cylinder pressure sensors. We're not done yet.

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.
