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
in mobile code).

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.

The keeps track of different sub widgets needed by other parts
of the code, notably:
MainTab
PlannerDetails
PlannerSettingsWidget
ProfileWidget2
DivePlannerWidget
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
would expect to get a pointer to some base class.
Therefore, directly store the properly typed pointers to the
widgets and simply remove the accessor functions. Why bother?

The location information shows a list of dive sites at the

Planned dives were still added by directly calling core code.
This could confuse the undo-machinery, leading to crashes.
Instead, use the proper undo-command. The problem is that as
opposed to the other AddDive-commands, planned dives may
belong to a trip. Thus, the interface to the AddDive command
was changed to respect the divetrip field. Make sure that
the other callers reset that field (actually, it should never
be set). Add a comment describing the perhaps surprising
interface (the passed-in dive, usually displayed dive, is
reset).
Moreover, a dive cloned in the planner is not assigned a
new number. Thus, add an argument to the AddDive-command,
which expresses whether a new number should be generated
for the to-be-added dive.

Originally, this was planned to be done via the signals from the

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.

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.

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 *.

9efb56e2d4 introduced rather complex

to the displayed dive.
This can be simplified by transporting the dive-id in the drag'n'drop

DivePictureModel--(1)-->DivePictureWidget--(2)-->ProfileWidget
For (1), we can use the Qt::UserRole role. This was used to transport
the picture-offset, but this is not needed anymore since ProfileWidget

In order to trigger the redraw of an edited dive we need to make sure
the model realizes that it has been updated. So far the only way to make
sure this happens reliably appears to be to remove the item and
re-insert it. Seems weird, but with this the bug of not redrawing the
profile after an edit appears fixed.

There were a handfull instances of the kind
1) gettextFromC::instance()->tr(...)
2) gettextFromC::instance()->trGettext(...)
1) is pointless, as tr is a static function.
All instances of 2) were likewise pointless, because trGettext()
returns a C-string, which was then immediately converted to a
QString.
Thus, replace both constructs by gettextFromC::tr(...).
After this change there was only one user of gettextFromC::instance()
left, viz. the C-interface funtion trGettext(). Therefore, remove
gettextFromC::instance() and do all the caching / translating
directly in the global trGettext().

When making a segment non-CCR, its setpoint should be 0.
OTOH, when it becomes CCR, use the default setpoint
(or should we try to find the last previous setpoint?)

Instead of a constant or a macro for the maximum
number of 'ws_info' elements the 100 literal was used.
Define MAX_WS_INFO in dive.h and use it everywhere.
Also clamp loops that iterate `ws_info' to MAX_WS_INFO.
Prevents potential out-of-bounds reading, similarly to
the previous commit about 'tank_info'.

In a number of places the global 'tank_info' array
is being iterated based on a 'tank_info[idx].name != NULL'
condition.
This is dangerous because if the user has added a lot of tanks,
such loops can reach 'tank_info[MAX_TANK_INFO]'. This is an
out of bounds read and if the 'name' pointer there happens to be
non-NULL, passing that address to a peace of code that tries
to read it (like strlen()) would either SIGSEGV or have undefined
behavior.
Clamp all loops that iterate 'tank_info' to MAX_TANK_INFO.

Correctly use gettextFromC::instance()->tr(); instead of a simple
tr(); to translate the dive mode names.

The list of known dive computers was stored in a multi-map indexed
by the device name. Turn this into a sorted QVector. Thus, no
map-to-list conversion is needed in the device editing dialog,
which distinctly simplifies the code.

helpers.h included qthelper.h and all functions declared in helpers.h
were defined in qthelper.h. Therefore fold the former into the latter,
since the split seems completely arbitrary.
While doing so, change the return-type of get_dc_nichname from
"const QString" to "QString".

On deletion of a single or multiple pictures, the whole DivePictureModel
was repopulated, which was clearly visible in the UI, owing to the
reconstructing of all images in the profile plot.
To avoid this vexing behavior, implement proper deletion routines in
DivePictureModel and ProfileWidget2. Since this needs sensible erase()
semantics the QList<PictureEntry> member of DivePictureModel was
replaced by a QVector. A QVector should be the default anyway, unless
there are very specific reasons to use a QList (which actually is
a deque, not a classical linked list).

The function removePicture() had a flag "last", which would indicate
that the called had finished removing pictures. Only then would
the model be recalculated.
This is a strange interface and, matter of fact, the caller was buggy:
if the last picture to be removed didn't have a proper url, removePicture()
was never called with "last" being set.
Change the interface to take a list of pictures to be deleted. This
will allow us to make picture deletion smarter in follow-up commits.

In the old code a combination of removeRows()/insertRows() was used
to signal a model reset.
Replace this by a single, modelReset signal. This saves a call to
plotPictures() and will allow us to be smarter in the future,
when removing pictures.
Reset-model and remove-items are semantically different.

on iOS it is practically impossible to copy the App log
to e.g. a mail! in iOS 11 the log file is stored within
the subsurface container and you first need to copy (actually
using the clipboard) out from there to the "normal" document
shared space, before it can be used.
At least iOS users (and I believe Android users) are not really
used to work with files, so the process is not easy to document
in an understandable way.
The alternative is to provide a button, which simply puts the
log on the general clipboard, allowing it to be pasted in a
multitud of applications.

The size of the to-be-created thumbnails was passed from DivePictureModel
to Thumbnailer. This became more and more bothersome, because the size
had to be stored with the request. Calling from Thumbnailer into
DivePictureModel was not an option, since this is not linked to all tests.
Therefore, move these functions to the Thumbnailer class.
Since the maximum thumbnail size is now known to the thumbnailer, the
dummy and failure images can be precalculated, which makes switching
between dives faster.

Connect the thumbnailer signal to the dive picture model slot.
This needs some code-reshuffling in the dive picture model.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
Create a new class, which performs all thumbnailing code.
This is mostly code reshuffling. Thumbnails are extracted
either from a cache or thumbnail calculation is started in
a worker thread.
Since getHashedImage() is called from a worker thread it
makes no sense to call subfunctions in yet another worker
thread. Remove these calls.
In contrast to the previous code, on error the background
thread produces a failure image, but it is not yet shown.
