4009d4c87f planner: remove DivePlannerPointsModel::setRecalc()
The only external user of setRecalc() was turning recalculation
on. In fact, this happened when constructing the planner-widget.
However, for example editing of the profile only works when
the recalc flag is on.

This is all very confusing, let's just turn the flag on by
default and remove the accessor. Internally, the planner can
simply use the std::exchange function to set and reset the
recalc flag.

Perhaps the setting/resetting can be replaced by simple
        recalc = true;
        ...
        recalc = false;
pairs. It is unclear whether there is need for recursion.
Something to be investigated.

2789bb05b1 profile: display arbitrary dive
So far the profile operated on the global displayed_dive. Instead,
take the dive to be displayed as a parameter to the plotDive()
functions.

This is necessary if we want to have multiple concurrent
profile objects. Think for example for printing or for mobile
where multiple dive objects are active at the same time.

1ec0790d50 planner: remove displayed_dive from DivePlannerModel
To remove global state, make the dive that DivePlannerModel
works on a member variable. Pass the dive in createSimpleDive()
and loadFromDive(). Moreover, this should pave the way to more
fine-grained undo in the planner. Ultimately, the planner
should not be modal.

Attention: for now, the dive must still be displayed_dive,
because of the convoluted way in which the profile and the
planner work on the same dive.

e419ebf55a planner: move clearing of model into loadFromDive() function
Both loadFromDive() callers were clearing the model before
calling loadFromDive(). Move the clearing into that function
since it makes no sense to load into a non-cleared model.

Apparently this changes the way that no-cylinder dives are
treated and the code in ProfileWidget2::repositionDiveHandlers()
must now explicitly check for that condition.

891839d254 planner: move same-time check to DivePlannerPointsModel
There must not be two dive planner points at the same time
stamp, as this violates the laws of physics (and internal
assumptions).

The corresponding test was done in the profile code at
two different places with floating point arithmetics.
This is a bad idea, because
1) code duplication
2) danger of rounding issues

Instead, do this in one central point in the planner model
and use integer arithmetics. Simply add a few seconds until
a unique timestamp is obtained.

dee1fea683 planner: implement move semantics in DivePlannerPointsModel
When reordering the points, the DivePlannerPointsModel would
not emit the appropriate move signals, but simply a data-changed
signal over all elements. This obviously violates Qt's
model/view API, though it is probably harmless. Let's do
the right thing so that the frontend knows that the selected
item changed place.

Also, emit dataChanged only on the actually changed element,
not all elements.

d68c3d8ab5 cleanup: add DivePlannerPointsModel::addDefaultStop() function
When clicking on "+" in the planner, a default stop point was
added using a signal/slot connection. This used the archaic
string-based connect syntax, because it was realized with
default parameters passed to "addStop()". Instead, add a
"addDefaultStop()" slot, which passes the default parameters.
Since all other callers do not use callbacks, unslotify
"addStop()". The slot was the only user of the default parameters,

a988e3c135 core: initialize dive selection after resetting the data
The dive selection was initialized during data-reset. However,
this emitted a signal before all data-reset routines were run.
Ultimately, this led to access-after-free in the statistics code.

Instead, move the select_newest_visible_dive() signal from the
divelist-model to the process_loaded_dives() function. There
is no point in initializing the selection if the dive data
is cleared after all.

This change broke closing of the log, because the UI-selection
was not reset. Therefore, when clearing the data, clear the
selection before proceeding with clearing.

764aa6c512 planner: remove DivePlannerPointsModel::startTimeChanged signal
The way the starting time of a new plan was set was bonkers:

1) PlannerWidgets::planDive() invokes DivePlannerPointsModel::
   createSimpleDive().

2) createSimpleDive() calls DivePlannerPointsModel::
   setupStartTime()

3) setupStartTime() emits a signal startTimeChanged()

4) startTimeChanged is caught by PlannerWidget and sets
   the UI field

5) change of the UI field emits a timeChanged() signal which
   is connected to DivePlannerPointsModel::setStartTime()

6) setStartTime() sets the time of the plan and displayed_dive
   and emits dataChanged()

7) dataChanged() replots the dive()

8) Back in DivePlannerPointsModel::createSimpleDive() the diveplan
   start time is overwritten with displayed_dive (the value are
   equal owing to 6)

Wow!

But it gets worse:

9) The initial dive plan is set up in createSimpleDive().

Since the profile is drawn in 7) after clearing the displayed_dive
and before constructing the initial plan, the profile is shown
on a dive without samples. It therefore generates a dummy profile.

To make this somewhat less insane, remove the startTimeChanged()
signal in 3), explicitly set the start time of plan and dive to
the one calculated by setupStartTime() and explicitly set the UI
filed in the plannerWidget.

This still indirectly draws the profile via signals in a convoluted
way, but at it straightens out things somewhat. Most importantly,
the profile doesn't have to generate a fake DC.

235146a95f profile: pass dive to DiveHandler
The DiveHandler shows a context menu where a cylinder can be
chosen. This indirectly accesses the global displayed_dive
variable.

Remove this in a step to make the profile reentrant.

The code was quite ominous: instead of simply generating the
list of cylinders, a global model was reset and then accessed
with Qt's cumbersome model/view API. All this trampling over
global state can be removed by simply making the function
that generates the list globally accessible.

975c123a30 profile: remove redundant code in DiveCalculatedCeiling
The DiveCalculatedCeiling profile-item has a recalc()
function, which calls "dataModel->calculateDecompression()".
This is a questionable reversal of control-flow: The
profile-item should paint the model-data not change it.

The code was supposed to be called under two conditions:

1) The value of the calcceiling3m preferences flag changed.
   This code was buggy for two reasons: Firstly, the cached
   value was always initialized to false, which means that
   sometimes the first call was missed. Secondly, the
   settingsChanged() functions was only called when closing
   the preferences window, not when changing the flag in the
   profile widgets.

2) The datetime of the dive changed. The whole control-flow is
   pretty absurd (due to "bit rot"):
     - The replan-dive command sends a date-time changed signal.
     - The main tab changes the date-time and informs the profile.
     - The profile sends a signal to the item.
     - The item instructs the model to recalculate the
       decompression.
     - The model causes the profile to be redrawn.

In any case, the whole thing is moot, because the decompression
is recalculated for *every* profile plot in create_plot_info_new().

Let's remove the code from the DiveCalculatedCeiling profile-item
and the calculateDecompression() function, which is now not
used anymore.

396598430b desktop: fix saving of column-widths of device and site tables
Qt's memory management scheme is completely broken and messes
with common expectations.

QObjects are organized as a tree. The children are destroyed
in the destructor of QObject. This means that they are destructed
after the destructor of the parent object has run and its
sub-object were destructed. Obviously, this makes no sense as
the child objects should be able to access their parent at
any time.

To restore the commonly expected deterministic order of
construction and destruction, one might simply do away with
Qt's silly object tree and organise things using classical
subobjects. However, that breaks with the Qt-generated UI
classes: The objects generated by these classes are *not*
destructed with the UI class. Instead, they are attached
to the widget's QObject tree. Thus these are again destructed
*after* the widget! Who comes up with such a scheme?

In our case this means that we cannot have models used for
TableViews as subobjects, because the TableView needs the
model to save the column widths in the destructor. Which,
as detailed above is called *after* the desctructor of the
widget! Thus, turn these models into heap-allocated objects
and add them to the QObject tree.

Funilly, this exposes another insanity of Qt's QObject tree:
Children are destructed in order of construction! One would
expect that if objects are constructed in the sequence
A, B, C one can expect that C can, at any time, access B and A.
Not so in Qt: The destruction order is likewise A, B, C!

Thus, take care to init the widgets before the model. Jeez.

Finally, print a warning in the column-saving code of
TableWidget, so that these kind of subtleties are caught
in the future.

dive). It is unclear to me whether that has to be that way,
as it depends on the chronological order of callbacks to
event_cb() and dive_cb().

Therefore add a device_table pointer to device_data_t
so that the downloader can add the device to this table. This
only adds the pointer, but does not yet use it in the
downloading code.

fd8bd9d5c7 cleanup: use std::string in struct device
struct device is a core data structure and therefore shouldn't use QString.
QString stores as UTF-16 (which is a very questionable choice in itself).
However, the real problem is that this puts us in lifetime-management
hell when interfacing with C code: The UTF-16 has to be converted to
UTF-8, but when returning such a string, this puts burden on the caller
who has to free it. In fact, instead of looping over devices from C-code
we had a callback that sent down temporary C-strings with qPrintable.

In contrast, std::string is guaranteed to store its data as
contiguous null-terminated and C-compatible strings. Therefore,
replace the QString by std::string. Keep the QString just in
one place that formats a hexadecimal number to avoid any
potential change.

The disadvantage of using std::string is that it will crash
when constructed with a NULL argument, consistent with C-style
functions such as strcmp, etc. Arguably, NULL is different
from the empty string even though we treat both as the same.

5bc6f5d36c cleanup: make device code more consistent with core
We keep track of device, i.e. distinct dive computers with id in the core.
The corresponding code stuck out like a sore thumb. Firstly, because it
is C++. But more importantly, because it used inconsistent nameing conventions.

Notably it defined a "DiveComputerNode" when this is something very different
from "struct dive_computer", the latter being the dive-computer related
data of a single dive.

Since the whole thing is defined in "device.h" and the function to create
such an entry is called "create_device_node", call the structure "device".
Use snake_case for consistency with the other core structures.

Moreover, call the collection of devices "device_table" in analogy
with "dive_table", etc.

Overall, this should make the core code more consistent style-wise.

cd22b86bf8 dive list: when moving dives, delete first and add later
When moving dives between trips, the core moves the dives internally
and sends a signal to the model. The model adds and removes the dives
accordingly. However, when adding the new dive, the old trip hasn't
changed its position, so the ordering is wrong leading to an inconsistent
state.

Therefore, remove the dives first and then readd them. There could
still be pathological cases where this fails. However, in the short
term this is an improvement. Note that in similar cases, the dives were
indeed removed then added, so this case here seems to be an oversight.

6ea0cc62b8 desktop: refine auto-fill of weights
In a previous commit, auto-filling of weight based on type was
changed to be only performed if the user hadn't already set a
weight, by testing for weight=0.

However, when the user edited the type and tabbed back and forth,
that counted as an edit and therefore the weight would not
change anymore.

To refine this, introduce an "auto_filled" flag to the weightsystem,
which is set if the weight is automatically filled and cleared if
the weight is edited. Update the weight if it was zero *or* auto-filled.

The flag is not saved to disk, but that should be acceptable. If the
user saves and reloads, we can assume that they meant the weight
to be set to the default value.

On the other hand, when changing the type after creation of a weight

for people who commonly use the same weight.

As a compromise, set the default weight only if it was unset. We
recognize this by a weight value of 0 g.

Moreover, it does bound checking and is more flexible with respect to

The affected code is in C++ and accesses the cylinder as reference or

fb6210a99a cleanup: invert control-flow when resetting the core structures
To reset the core data structures, the mobile and desktop UIs
were calling into the dive-list models, which then reset the
core data structures, themselves and the unrelated
locationinformation model. The UI code then reset various other
things, such as the TankInformation model or the map. . This was
unsatisfying from a control-flow perspective, as the models should
display the core data, not act on it. Moreover, this meant lots
of intricate intermodule-dependencies.

Thus, straighten up the control flow: give the C core the
possibility to send a "all data reset" event. And do that
in those functions that reset the core data structures.
Let each module react to this event by itself. This removes
inter-module dependencies. For example, the MainWindow now
doesn't have to reset the TankInfoModel or the MapWidget.

Then, to reset the core data structures, let the UI code
simply directly call the respective core functions.

4d407dc666 pictures: turn QString into std::string for filenames
For undo of picture manipulation, it will be crucial that the
model and the core have the same order of pictures. The first
sort criterion will be time, the second filename in the case
that two pictures have, for whatever reason, the same timestamp.

However in the core we us C-strings and thus sort byte-wise
using strcmp. In the Qt-part we use QStrings, which sort according
to unicode encoding. To enable consistent sorting, change the
Qt-part to std::string, which uses a C-style 0-terminated string
as its backing store.

One might argue that in general filenames should use system-encoding
and therefore use std::string instead of QString. However, a
broader conversion to std::string turned out to be very painful,
since Qt is (deliberately?) difficult to use with std::string.
Notable all the file-manipulation functions don't take std::string
by default. Thus, this commit only converts the internal data
of DivePictureModel, but continues to use QString for the Qt-facing
interface.

f9f4a9c232 debug output: ensure our debug output is captured on Android
I would have bet money that Android used to send stderr to the logcat
log, but apparently it doesn't (anymore?). So in order to be able to
have a chance to debug weird cloud storage issues on Android, let's do
some wholesale replacement of fprintf(stderr,...) with our own version
of the INFO macro that we long ago borrowed from libdivecomputer (and
rename it to ensure we don't have a conflict there).

0ccc0f04bb dive sites: properly reload dive site model on desktop
In 9310d72943, resetting of the dive
sites was moved to DiveTripModelBase::reset(). This seemed like a
good idea, because it means that the location list is reloaded
every time the dive list is reset.

Unfortunately that function is only used on mobile, thus on desktop
the dive site model is not updated. Do that in
MultiFilterSortModel::resetModel(), because this is always called
when the dive list is reset. Desktop differs from mobile in that
two different models are used depending on whether we are in list
or in tree mode.

Fixes #2749

8b93d67106 mobile: remove fine-grained notification
When initializing the fulltext-cache and the dive-list, every
100 dives a notification was shown. I had a feeling that this
made startup significantly slower, but that could have been
purely psychological.

Therefore I measured and indeed, removing the fine-grained
notification, it becomes *significantly* faster. For a 3500
dives test log with mobile-on-desktop:

Initialization of the fulltext: 1350 ms -> 730 ms (-46%)
Initialization of the divelistmodel: 689 ms -> 113 ms (-83%)

Let's remove the fine-grained notification. There *is* a visual
indication of work-in-progress anyway.

24a7dbde16 CylindersModel: use flag to decide whether we are in planner
On desktop, we have two CylindersModel concurrently: One in the
planner and one on the equipment-tab. They act differently, because
the former modifies displayed_dive directly, the latter issues
undo commands.

To differentiate, we used the in_planner() function. However, that
appears extremely brittle, especially when combined with undo-commands.
Therefore when generating the model, pass in a parameter that says
whether this is for the planner or the equipment tab and use
that flag to decide how to act.

01fa983182 undo/cylinder: call undo command to edit cylinder fields
Call an undo command when editing cylinders, but only if on
the EquipmentTab.

To keep code changes small, make a copy of the cylinder first,
then edit the cylinder as before and then either call an undo
command (EquipmentTab) or overwrite the old cylinder (Planner).

The memory management here is a bit strange: Since the undo-command
itself makes a deep-copy of the passed in cylinder, we only do
a shallow copy. If we have to change the type, we allocate the
string with an std::string, so that the memory is automatically
freed at the end of the function. However, this means that in
the planner we have to make a deep copy first, swap old and
new cylinder and finally release the old cylinder. Certainly
not ideal, but for now the pragmatic thing to do.

1dcc885bb2 undo/cylinders: Implement editing of the type
This one is tricky, as when browsing through the types-combobox,
the user is presented with presets without actually changing the
dive. We do not want an undo-command for every change-event in
the combo-box.

Therefore, implement a scheme analoguous to the weight-editing:
A temporary row can be set / committed or reset. Sadly, the
code is more complex because we have to consider the planner,
which is not included in the undo system.

Firstly, the planner uses a different model, therefore all
interactions are channeled through setData() with special roles.
Secondly, in the planner we shouldn't place an undo command,
but simply overwrite the dive.

To mark invalid dives, we use a struck-out font, which was a static
variable at translation unit scope, i.e. initialized at application

It is unclear when we can initialize fonts. Try to move initialization
to the constructore of DiveTripModelBase and make the font a member
of that class. For consistency, also make the invalidBrush a member
of this class.

This now means that the diveData function cannot be static anymore,
since it needs access to the font and brush. But OK.

9310d72943 models: update divesite-model when clearing/updating dive model
When the dive list is cleared or updated, the entries in the
divesite-model become stale and therefore the divesite-model
(with the actual name LocationInformationModel) also must be
updated. This was done manually in some parts of the code and
forgotten in others. Therefore, do it directly in the clear()
and reset() function of the dive list-model.

This might be a bit of a layering violation: why should one
model call into another if they are not in parent/child
relationship? However, this seems easier than introducing
a global "reset dives" function that coordinates the models.

Moreover, it does not appear 100% safe: if the clearing of
the divesite model causes accesses to the divelist-model,
they happen in the midst of a model reset and we had horrible
bugs with that kind of things. However, I don't think that
should happen.

MobileSwipeModel is probably not an ideal name, but all I could come up with.

One of the main complications here is that our list is reversed with respect to
the source model. We should change that one day.  Probably by moving the
sorting down to the core-model.

Since looking up the source row is somewhat expensive, the lookup is cached for
a single entry because accesses come in bursts for a single dive. This should
be a good compromise and avoids keeping track of a full row-to-dive array.
