The logic in process_imported_dives() was faulty: Dives are merged
trip-wise in a loop. But if only autogenerated trips were supposed
to be merged, the trip would not be added.
Change the logic to always add the trip if it is not merged. To make
the loop easier to read, factor out the merge-trip-into-existing-trips
logic into a separate function.

Split the process_imported_dives() function in two:
1) process_imported_dives() processes the dives and generates
a list of dives and trips to be added and removed.
2) add_imported_dives() calls process_imported_dives() and
does the actual removal / addition of dives and trips.
The goal is to split preparation and actual work, to
make dive import undo-able.
The code adds extra checks to never merge into the same
dive twice, as this would lead to a double-free() bug.
This should in principle never happen, as dives that
compare equal according to is_same_dive() are merged
in the imported-dives list, but perhaps in some pathologival
corner-cases is_same_dive() turns out to be non-transitive.

When importing log-files we generally want to merge trips. But
when downloading and the user chose "generate new trip", that
new trip should not be merged into existing trips.
Therefore, add a "merge_all_trips" parameter to process_imported_dives().
If false only autogenerated trips [via autogroup] will be merged.
In the future we might want to let the user choose if trips
should be merged when importing log-files.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
The old way of merging log-files was not well defined: Trips
were recognized as the same if and only if the first dives
started at the same instant. Later dives did not matter.
Change this to merge dives if they are overlapping.
Moreover, on parsing and download generate trips in a separate
trip-table.
This will be fundamental for undo of dive-import: Firstly, we
don't want to mix trips of imported and not-yet imported dives.
Secondly, by merging trip-wise, we can autogroup the dives
in the import-data to trips and merge these at once. This will
simplify the code to decide to which trip dives should be
autogrouped.

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:

If no dives are selected when trying to export a selection, a message
is shown that no dives were selected, but it's immediately hidden
behind a message saying that a temporary file could not be created.
In fact, the creation of the temporary file wasn't never attempted,
so the message that the user actually sees is misleading.
The solution chosen here is to duplicate the check that at least some
dives are selected, and abort early if that case is detected, rather
than continuing on to show the additional misleading message. Not
elegant, but it gets the job done.
Better solutions to this include refactoring prepare_dives_for_divelogs
to return something more descriptive than a bool, remove that check
from prepare_dives_for_divelogs entirely since it doesn't seem to be
a good fit there, or switch to exceptions for handling these problems
rather than return values. I don't have sufficient familiarity with

To make data flow more clear, unglobalize the downloadTable object.
Make it a subobject of DownloadThread. The difficult part was making
this compatible with QML, because somehow the pointer to the
download-table has to be passed to the DiveImportedModel. Desktop would
simply pass it to the constructor. But with objects generated in QML
this is not possible. Instead, pass the table in the repopulate()
function. This seems to make sense, but for this to work, we have to
declare pointer-to-dive-table as a Q_METATYPE. And this only works
if we use a typedef, because MOC removes the "struct" from "struct
dive_table". This leads to compilation errors, because dive_table is

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.

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.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

because users typically want their new dives top, "ascending"

The DiveListView code had a very fundamental problem with its
header: Each had its own idea of who is responsible for sorting.
Since we can't easily change QHeaderView, accept QHeaderView
as the authority on sort-column and order.
To make this possible, split the reload() function in two
distinct functions:
- reload() reloads the model and sorts according to the
current sort criterion.
- setSortOrder() tells the header to display a certain
sort criterion. If this is a new criterion, it will then
emit a signal. In this signal, resort according to that
criterion.
Thus, the actual sorting code has to be moved from the
headerClicked() to a new sortIndicatorChanged() slot.
Morover, the sorting of the QHeaderView has to be used.

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

In commit 9829e49815 the dive
selection code was moved from the filter to the dive list.
As a consequence of that change, the selectionChanged signal
was not emitted anymore and therefore the map widget was not
informed of the new dive site list. This had funky effects on
the dive-site editing. Notably, changing the location would
move the map, but not update the flag.
Explicitly emit selectionChanged in filterFinished() to fix
dive site editing.

After invalidating the filter, the dive-selection was modified to
ensure that at least one dive is selected. This was done in the
filter code, but it seems preferrable to do this in the dive-list
code, which has direct access to the selection-model.
Therefore, move the code from MultiFilterSortModel to DiveListView.
While doing so, split the code in DiveListView into more functions to:
1) Get the index of the first dive (if any).
2) Select the first dive (if any).
This allows a distinct size reduction of conditional compilation
in MultiFilterSortModel (accesses to MainWindow are not possible

The keeps track of different sub widgets needed by other parts

MainTab
PlannerDetails

DiveListView
Access to these widgets was provided with accessor functions.
Now these functions were very weird: instead of simply returning
pointers that were stored in the class, they accessed a data
structure which describes the different application states.
But this data structure was "duck-typed", so there was an
implicit agreement at which position the pointers to the
widgets were put inside. The widgets were then down-cast by
the accessor functions. This might make sense if the individual
widgets could for some reason be replaced by other widgets
[dynamic plugins?], but even then it would be strange, as one

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.

In DiveListView, we have a very fundamental problem: When
On the one hand, we get informed of user-selection in the
DiveListView::selectionChanged() slot. This has to set the
correct flags in the C-backend.
On the other hand, sometimes we have to set the selection
programatically, e.g. when selecting a trip. This is done
by calling QItemSelectionModel::select().
But: this will *also* call into the above slot, in which
we can't tell whether it was a user interaction or an
internal call. This can lead to either infinite loops or
very inefficient behavior, because the current dive
is set numerous times.
The current code is aware of that and disconnects the
corresponding signal. This is scary, as these signals are
set internally by the model and view. Replace this
by a global "command executing" flag in DiveListNotifier.
The flag is set using a "marker" class, which resets the flag
once it goes out of scope (cf. RAII pattern).
In DiveListView, only process a selection if the flag is not
set. Otherwise simply call the QTreeView base class, to reflect
the new selection in the UI.
To have a common point for notifications of selection changes,
add such a signal to DiveListNotifier. This signal will be
used by the DiveListView as well as the Command-objects.

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.

This refactors the undo-commands (which are now only "commands").
- Move everything in namespace Command. This allows shortening of
names without polluting the global namespace. Moreover, the prefix
Command:: will immediately signal that the undo-machinery is
invoked. This is more terse than UndoCommands::instance()->...
- Remove the Undo in front of the class-names. Creating an "UndoX"
object to do "X" is paradoxical.
- Create a base class for all commands that defines the Qt-translation
functions. Thus all translations end up in the "Command" context.
- Add a workToBeDone() function, which signals whether this should be
added to the UndoStack. Thus the caller doesn't have to check itself
whether this any work will be done. Note: Qt5.9 introduces "setObsolete"
which does the same.
- Split into public and internal header files. In the public header
file only export the function calls, thus hiding all implementation
details from the caller.
- Split in different translation units: One for the stubs, one for
the base classes and one for groups of commands. Currently, there
is only one class of commands: divelist-commands.
- Move the undoStack from the MainWindow class into commands_base.cpp.
If we want to implement MDI, this can easily be moved into an

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

Under certain conditions the user was presented an ugly

- The name-proposing code searched for dive sites *starting*

If the user entered a text contained by a dive site name, but
no dive site would start with the second line was filled with
a dummy text. This text would be kept if it contained the text

Yet, this never worked, because the actual dive site of the selected
dive had precedence in centerOnDiveSite().
It seems that centerOnDiveSite() had actually to purposes:
1) center on the passed in dive site
2) center on the dive sites of the selected dives
Therefore, split this function in two separate functions for
each of these use-cases. This allows us to remove some pre-processor
magic (mobile vs. desktop) and to remove a parameter from the
MainTab::diveSiteChanged() signal.

If only selected dives were exported into HTML, the statistics would
nevertheless cover all dives. A counter-intuitive behavior. Fix by
adding a selected_only flag to calculate_stats_summary().

The statistics of the selected dives were calculated
a) into a global objects and
b) at a completely different place than where they're used.
There's no plausible reason for either. There fore render
into a caller-provided structure at the place of use.

Statistics were calculated into global variables every time the
current dive was changed.
Calculate statistics only when needed and into a structure
provided by the caller.
