35b33b8c6a mobile/divelist: add first version of new MobileListModel proxy model
Create a model which represents all top-level items and, potentially, one
expanded trip as a flat list.

Pass down roles to the source model and let the source model handle that. We'll
have to do some ifdef-ery, but so be it.

Additionally, compile the base model on mobile as well.
This contains a couple of hacks to make things compile at all.

If compiled on mobile, on change of the current dive, don't send

ee553e059d Filter: move actual filtering loop to core/divefilter.cpp
The DiveFilter class defined the showDive() function to test
whether a dive should be filtered or not. This was used in
DiveTripModel to loop over all dives or all dives affected by
an editing action.

This restricts us in how we do filtering: We can't use indexes
that give us directly the result. To make the filtering more
flexible, move the actual loops that do the filtering to
the DiveFilter class.

The undo-commands likewise called directly the showDive()
function to check whether newly added dives are shown.
Use the new interface here as well.

a45c5faa8c Filter: update current dive if change hides current dive
When changing the filter-criterion and the current dive is
hidden, a new dive is made current. However, when a dive is
hidden because it was edited, it is still shown.

Make this consistent by also selecing a new current dive
in the latter case. Do this by comparing the current_dive
before and after calculating the filter. Since this is now
done in multiple places move this code to the ShownChange
class.

7633d5feec Dive list: filter dives at DiveTripModel level
We use a QFilterProxyModel to filter out dives that are hidden
according to the current filter-criterion. Instead, filter the
dives already at the DiveTripModel level. Filter out hidden
dives immediately when receiving them. The only difficult case
is when dives are changed, because then visibility can change.
This means that we have three cases to consider:
  1) Visibility unchanged -> send change signal
  2) Change from hidden to unhidden -> add dives to model
  3) Change from unhidden to hidden -> remove dives from model
Things get complicated by the fact that the tree-version of
the model might have to add/remove full trips!

7e12ac262b Dive list: implement DiveTripModelBase::reset()
On desktop, resetting the model is realized by generating a new
model object. This is due to the fact that we have two different
models (tree and list) and for switching between those, we have
to create a new object.

On mobile, currently there are no plans to support the list-mode.
Therefore, there is no reason the recreate the object. Instead,
implement a reset() function that reloads the core data.

send a signal and hook into the signal from the model. This
will allow us to remove the DiveListModel::instance() function.

This, in turn, is a step towards supporting multiple models

sets the hidden_by_filter flag in the core and therefore

2f77716e8f Dive list: signal correct trip in DiveTripModelTree::topLevelChanged
DiveTripModelTree::topLevelChanged() has pretty complex code, as
it has to handle the fact that when adding/removing a dive from
a trip, the trip can change its position.

The code did not account for the fact that when moving an object
back in the top level list, one has to subtract one from the new
index, because the object was removed somewhere in the front of
the list.

To make matters worse, when an entry stayed where it was, this
was realized by moving the entry right behind itself, which of
course means that it stays where it is. But this meant that in
the by far most common case (no moving) the wrong entry was
updated.

Fix this by subtracting 1 from the new index when moving an
entry to the back.

794066b236 Cylinders: access cylinders with get_cylinder()
Instead of accessing the cylinder table directly, use the get_cylinder()
function. This gives less unwieldy expressions. But more importantly,
the function does bound checking. This is crucial for now as the code

cylinder tables. Accesses of invalid cylinder indexes may lead to
silent data-corruption that is sometimes not even noticed by
valgrind. Returning NULL instead of an invalid pointer will make

7c9f46acd2 Core: remove MAX_CYLINDERS restriction
Instead of using fixed size arrays, use a new cylinder_table structure.
The code copies the weightsystem code, but is significantly more complex
because cylinders are such an integral part of the core.

Two functions to access the cylinders were added:
get_cylinder() and get_or_create_cylinder()
The former does a simple array access and supposes that the cylinder
exists. The latter is used by the parser(s) and if a cylinder with
the given id does not exist, cylinders up to that id are generated.

One point will make C programmers cringe: the cylinder structure is
passed by value. This is due to the way the table-macros work. A
refactoring of the table macros is planned. It has to be noted that
the size of a cylinder_t is 64 bytes, i.e. 8 long words on a 64-bit
architecture, so passing on the stack is probably not even significantly
slower than passing as reference.

f27d440bb3 Dive site: don't emit divesChanged signals when editing dive site
When editing the dive site, for certain fields a divesChanged signal
was emitted so that the dive-list can be updated.

Arguably it is wrong to decide which fields are relevant to the
dive list in the undo-command code. Therefore, let the list
catch the dive-site-edited signal and decide itself.

But the actual reason for this commit is that if the dive-site
field of a dive changes, we might have to reload the dive-location-model
because suddenly a new dive site appears. Now if this is done
in QML context on some Qt version (notably 5.9) we get crashes
later on. But that can happen if the user moves a flag. So in that
case only send a diveSiteChanged signal.

This seemed like a good idea at first, but when more and more parts used
these signals, it became a burden. Therefore push the batching to the

The divesAdded and divesDeleted are not yet converted, because these
are combined with trip addition/deletion. This should also be detangled,
but not now.

dive-list model now does its own sorting. This will have to be

cbcddaa396 Dive list: cache shown flag in model (quick-fix for undo-crash)
We have a very fundamental problem with data-duplication in
core and qt-models. In a particular case, this led to an easily
reproducible crash:
1) An undo command moved the last dive of a trip to another.
2) When an undo-command removed the last dive of
   a trip to a different trip, the dive was removed from the
   trip in the core. Then, the model was updated.
3) That lead at first to a rearrangement of the trips, because
   the trip with the added dive is moved before the trip with
   the removed dive.
4) In such a case, the filter-model checks the visibility of
   the trip.
5) Since the trip with the removed dive has no dives in the core,
   visibility was determined as false.
6) From this point on the mappings of the QSortFilterProxyModel
   were messed up. Accesses led to crashes. It is unclear
   whether this is a Qt bug or only a QOI issue.

As a quick-fix, cache the visibility flag of trips directly
in the Qt-models. Don't set the visibility directly in the
core, but go via the Qt-models. Thus, a more clear layering
is achieved.

In the long run, we can hopefully get rid of the data-duplication
in the models.

f1fc89b978 Dive list: split DiveTripModel into distinct models (tree and list)
The DiveTripModel was used to represent both, trip and list views.
Thus many functions had conditionals checking for the current mode
and both modes had to be represented by the same data structure.

Instead, split the model in two and derive them from a base class,
which implements common functions and defines an interface.

The model can be switched by a call to resetModel(), which invalidates
any pointer obtained by instance(). This is quite surprising
behavior. To handle it, straighten out the control flow:

DiveListView --> MultiFilterSortModel --> DiveTripModelBase

99b2de85b5 Dive list: fix off-by-two bug in DiveTripModel
Commit 911edfca71 changed the dive list
on desktop to update positions of trips when adding/removing dives.
A very unlikely case, but necessary for consistency.

For a trip to be moveable down, its index has to be one-less than
the maximum index, which is "items - 1". The code was doubly wrong:
it forget the "1" and checked for less-or-equal instead less-than.
Thus this was effectively an off-by-two error. Fix it.

There are now three sorting functions:

7046c8b342 Dive list: invert sort-direction to reflect core
Traditionally, the DiveTripModel has its data sorted in opposite
direction to the core-data (chronologically descending vs. ascending).
This bring a number of subtle problems. For example, when filling
the model, trips are filled according to the *last* dive, whereas
later insertion points are according to the ->when value from the
core, which depends on the *first* dive.

As a start of fixing these subtleties, change the sort direction
to reflect the core-data. Ideally, this should lead to a removal
of the redundant data-representation.

Since the model is now sorted in ascending order, sorting has to
be enabled in the DiveListView constructor to reflect the
default-descending order.

ab894c9b64 Dive list: implement custom lessThan function
The dive list was sorted using the default-sorter of
QSortFilterProxy model. This is mighty inflexible as it
considers only one column. This has the funky effect that
for rows with identical elements, the sort order depends
on the previous sorting.

Implement a lessThan() function in the MultiFilterSortModel,
which simply hands the sorting down to the actual model.
This might be considered a layering violation, but it makes
things so much easier.

Sadly, it seems like the column-to-be-sorted is transported
in the provided indices. Therefore, the comparison is chosen
using a switch for *every* comparison. It would seem much
more logical to set a function pointer once and use that.
Further investigations are necessary.

803111ef02 Dive list: make filter model aware of its source
The data-flow from C-core to list-view is as follows:

C-core --> DiveTripModel --> MultiSortFilterModel --> DiveListView

The control-flow, on the other hand, differs as DiveListView
accesses both MultiSortFilterModel and DiveTripModel, whereas
MultiSortFilterModel is mostly unaware of its source model.

This is in principle legitimate, as the MultiSortFilterModel might
be used for different sources. In our particular case, this is
not so. MultiSortFilterModel is written for a particular use case.

Therefore, model control-flow follow after data-flow: Let MultiSortFilterModel
set its own source model and DiveListView access the MultiSortFilterModel,
which then manages its source model.

This is not bike-shedding, but will enable a more flexible and
higher-performance sorting.

32df0ab0da Cleanup: remove DiveItem and TripItem classes
The DiveItem and TripItem classes were wrappers around dive * and
dive_trip * used to extract tabular data. With the rework of
DiveTripModel they lost all their state besides the pointer itself.
The usage was:
	DiveItem item(d);
	item.data(...);
This can now be simplified to the much more idiomatic
	diveData(d, ...);
and analoguously for TripItem.

While adapting the data() function to be part of DiveTripModel, change
the
	QVariant ret
	switch(...) {
	...
	case ...:
		ret = ...;
		break;
	...
	}
	return ret;
style to
	switch(...) {
	...
	case ...:
		return ...;
	}
Not only is this shorter and easier to reason about, it generally also
improves the generated code. The compiler can directly construct the
return value in the buffer provided by the caller. Though modern
compilers start to be very good at avoiding unnecessary copies.

In total this cleanup results in a net-reduction of 190 lines of code.

7067e33596 Undo: select dives after add, remove, merge, split dive commands
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.

ec7d85835f Dive list: implement proper Qt-model semantics for DiveTripModel
Previously, each dive-list modifying function would lead to a
full model reset. Instead, implement proper Qt-model semantics
using beginInsertRows()/endInsertRows(), beginRemoveRows()/
endRemoveRows(), dataChange().

To do so, a DiveListNotifer singleton is generatated, which
broadcasts all changes to the dive-list. Signals are sent by
the commands and received by the DiveTripModel. Signals are
batched by dive-trip. This seems to be an adequate compromise
for the two kinds of list-views (tree and list). In the common
usecase mostly dives of a single trip are affected.

Thus, batching of dives is performed in two positions:
- At command-level to batch by trip
- In DiveTripModel to feed batches of contiguous elements
  to Qt's begin*/end*-functions.

This is conceptually simple, but rather complex code. To avoid
repetition of complex loops, the batching is implemented in
templated-functions, which are passed lambda-functions, which
are called for each batch.

4fbb8ef399 Dive list: hand-code the DiveTripModel
The dive list is fed data by means of a sorted "DiveTripModel".
There are two modes: list and tree. This was implemented rather
elegantly with a general "TreeModel", which can represent trees
of arbitrary depths.

Nevertheless, we have at most two levels and on the second level
only dives can reside. Implementing proper model-semantics
(insert, delete, move) will be quite a challenge and implementing
it under the umbrella of a very general model will not make it
easier.

Therefore, for now, hardcode the model:
At the top-level there are items which may either be a trip
(can contain multiple dives) or a dive (contains exactly one dive).

Thus, we can completely de-virutalize the DiveItem and TripItem
classes, which are now trivial wrappers around dive * and dive_trip *.
