c34f0b88a2 profile: move checking for DiveTextItem into its own function
When creating the context menu, a special menu is created for
the dive computer name.

This was checked in a loop, that set a flag and exited early.

This can all be simplified by moving the loop into its own
function. No more flag, less indentation. Overall better.

78f4d7b2b9 profile: simplify checking for DiveTextItem
When creating the context menu on the profile, the code has
to check whether the context menu is activated on the
dive computer name to show a special menu (delete / split
dive computer).

This was done by setting a special property on the item
and then checking for that property on the item that
the menu is invoked on or its parents.

The reason the code didn't simply check the pointer was
probably that DiveTextItem uses multiple inheritance:
It derives from QObject and QGraphicsItem. It has to derive
from QObject first, because (the ridiculously broken) MOC
needs it that way. The object added to the scene is a
QGraphicsItem. Thus, we get a pointer _into_ the DiveTextItem
object.

However, that's all completely unnecessary. We can simply
compare the pointers, as the compiler will understand that
QGraphicsItem is only the second base class of DiveTextItem.
Magic!

Let's remove the cruft and simply compare the pointers.

bd6b714be1 profile: ignore animation-speed setting when printing
When printing, the animation speed was set to 0 by the
caller and later reset to the original value. Instead of
modifying global state, set it internally (in the profile-code)
to zero when in print mode.

This is another small step in making the printing independent
from the shown profile.

8939b6a99b profile: remove enableToolbar() signal
When showing the "empty-state", the profile toolbar was
disabled. This was done via a "reverse" signal from the
profile to the MainWindow. Instead control the toolbar
in the MainWindow directly. Break out the plot-dive
functionality into a member function and there test
whether a dive is shown or not.

The signal makes no sense in the context of mobile
or printing.

4daf687876 profile: remove [disable|enable]Shortcuts() signals
When switching to the "plan" or "add" (which should rather be
called "edit", by the way) mode of the profile, the "shortcuts"
for copy&paste, undo&redo, etc. are disabled. When switching
to "profile" mode, they are reenabled.

This was done in a most convoluted way:

- The MainWindow calls the set*State() function of the profile.
- The Profile emits [disable|enable]Shortcuts() signals.
- The MainWindow catches these signals and does the enabling
  or disabling.

Not only is this very hard to reason about, it is also in
contradiction to the profile being part of the display layer.

Moreover, in editCurrentDive() the MainWindow disabled the
shortcuts itself, so this was all redundant.

For the sake of sanity, let's just move this logic to the
MainWindow, unslotify the [disable|enable]Shortcuts() functions
and make them private.

77a6bc6d62 profile/planner: don't update dive in ProfileWidget2::plotDive()
In planner or profile-edit mode, the plotDive() function takes
the current plan and turns it into a dive profile. Not only
is this a layering violation (the display layer modifying the
dive), it is also fundamentally flawed. The control-flow is
out of control, if you wish. There are numerous reasons why
the profile needs to be replot, many of which do not need
a recalculated dive profile.

Move the code that updates the dive-profile to the
DivePlannerPointsModel. Thus, the profile recalculations
and replots can be pooled. This will break the planner, since
there now might be missing calls to the profile recalculation.
But it already has some positive effects: when removing
multiple points, the profile is only recalculated once.

This will need much more work, but it is a start.

337d9318ad planner: split addStop() into external and internal versions
The DivePlannerPointsModel::addStop() function is called by
the profile to add a planner-stop. It is also used internally
to create profiles.

If we ever want to include this in the undo system, we have
to split these into to versions. One will ultimately place
an undo command and update the profile, the other one doesn't.

For now, this makes the external interface simpler, as some
parameters are redundant.

71e117669d profile: populate dive handlers when switching to edit/plan mode
The dive handlers are only updated by signals. This means that
switching into edit-mode has to be done in steps:
 1) initialize the DivePointsPlannerModel
 2) switch profile mode
 3) load dive into DivePointsPlannerModel

2) and 3) cannot be exchanged, or the dive handlers are not
initialized.

To avoid this sandwitching of profile- and model-initialization,
populate the dive handlers when switching the profile mode.
Thus, the profile can be switched into edit/plan mode when
the DivePointsPlannerModel is fully initialized.

This will be important in upcoming commits, when the initialization
of the dive is moved from the profile to the DivePointsPlannerModel.

4b801f1f50 planner: split createTemporaryPlan() function.
The DivePlannerPointsModel::createTemporaryPlan() function had
two distinct and independent parts:
 1) create the data points.
 2) create the dive sample and calculate variations.
The second part was only exectuted if the recalc flag was set.
Out of the two callers, one was explicitly disabling and setting
the recalc flag to avoid the second part.

The much more logical thing is to simply split the function in
two and only call the first part.

To avoid any functional change, the second caller (the profile)
still tests for the recalc flag. However, if it shouldn't replot
a new plan, why calculate it in the first place!? And why does
the display function change the plan at all? This appears all
very ill-thought out and should be changed in due course.

457be51ff6 profile: remove redundant replot() calls in key events
When moving "dive handlers" with the cursor keys, the
profile was replot twice:

- First the recalculation of the planner model was suspended.
- The "stop" was moved.
- This led to a replot by a signal from the planner model.
  However, the old profile was shown, since the recalculation
  was suspended.
- The recalculation was reenabled.
- The profile war replot, resulting now in the correct profile.

A classical case of bit rot.

Instead, don't suspend calculation in the first place. This
shows the correct profile on the first replot and the second
replot can be removed.

a3d8191896 profile: make ItemPos initialization constant
The ItemPos structure describes the position of various chart
elements on the scene. It had two problems:

- The identifiers were starting with an underscore followed
  by a capital letter. This is reserved to the compiler.
- The global object was initialized in the ProfileWidget's
  constructor. This means that if there are multiple
  ProfileWidgets, the structure is reinitialized even though
  it is constant.

Remove the underscores (what was the point anyway?) and
initialize the structure in its own constructor. Moreover,
make the object const to drive the point home.

If this ever needs to be variable, each ProfileWidget
should get its own copy of the object.

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

item changed place.

Also, emit dataChanged only on the actually changed element,

79ddb23edf profile: implement proper model/view semantics in ProfileWidget2
The ProfileWidget2 slots, which reacted to model changes were
broken. They did not add / remove items at the changed positions,
but arbitrarily at the end. Moreover, they assumed that only
a single item was added / removed and thus violated the model/view
API.

This worked because the handles are completely reset after each
operation and the model only ever touched single items.
Nevertheless, this has to be fixed if we ever want finer grained
undo.

This one is extremely obscure: TankItem::setData(), which is
called on every replot, was passed the DivePlotDataModel,
even though it doesn't access that model at all.

Instead, it connect()s to the model to stay informed of changes
to the data. First of all, this should obviously be done
once in the constructor, not on every replot.

But also, the setData() function is called on every replot
one lines before sending the model-changed signal.
Thus, the tankitem was always repainted twice.

Just remove the whole connect() thing and go for a more
deterministic model. Should the tankbar not be repainted
anywhere, add the appropriate calls there.

Accordingly rename the "modelDataChanged" slot to "replot".

ea88f4729d profile: set model of profile items on construction
The profile items had a "setModel()" function to set
the DivePlotDataModel post creation. The model is never
changed. It does however mean that the model might be
null in a short period between construction and setting
the model.

To simplify reasoning about this code, set the model
in the constructor. To drive the point home that the
can never change and cannot be null, turn it into a
reference.

Yes, this is gratuitous bike-shedding, but it helps

196bd7b7b2 profile: remove clearHandlers function (fixes crash)
Recently (674c20227b), the call to ProfileWidget::clearHandlers()
was moved from PlannerWidgets::replanDive() to ProfileWidget2.
This cause a crash, because the code assumes that the number
of elements in the handles-vector the divepointplanner model
is the same.

Clearing the handles violates this assumption. It turns out
that the clearHandlers() function is broken anyway: it clear
the handles-vector, but not the gases-vector, which should
likewise have the same number of elements. It appears that
the clearHandlers() function is an artifact and it is
mysterious how this has worked so far. Remove.

fceb3691d9 profile: move picture removal from DivePictureItem to ProfileWidget2
On clicking the DivePictureItem "trash" icon, the item would delete
the picture it represents in the currently displayed dive. This needed
an access to the global "displayed_dive" variable, which we want
to get rid of to make the profile more flexible. For example, we
want to render the profile for printing without messing with global
state.

One solution would be to save the dive with every DivePictureItem.
This commit follows a more Qt-ish strategy by handling this via
signals: The close button emits a signal that is recast by the
DivePictureItem and ultimately handled by the ProfileWidget2,
which knows which dive it represents.

17556cc66c profile: don't interpret NULL as current_dive in plotDive()
ProfileWidget2::plotDive() had this weird interface, where passing
in NULL as dive would mean "show current_dive". However, most callers
would already pass in current_dive. Therefore, unify and always pass
in current_dive if the caller wants to draw the current dive.

This allows us to interpret NULL as "show empty profile". Thus,
passing in current_dive when there is no current_dive simply shows
an empty profile. This makes the calling code in
MainWindow::selectionChanged() simpler.

f4b948e80d profile: properly update lastgasmix when populating events
When populating the events of a profile, a pointer to the current
gasmix was passed around to properly calculate isobaric_counterdiffusion.
The DiveEventItem::setupToolTipString() function updated this gasmix
when processing gas change events.

I inadvertently broke the code when replacing gasmix-pointers by
values. We could of course simply revert this part of the commit.
However, the data flow was horrible anyway: for example is supposed
that the setup functions were called in the correct order (i.e.
DiveEventItem::setupToolTipString() is called after all other
functions using the gasmix). Not exactly easy to follow.

Therefore, keep passing around the gasmix as value to make it clear
that the functions don't modify it. Keep the gasmix up-to-date at
the caller's site in ProfileWidget2::plotDive().

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.

ec8e109a1a Profile: remove ProfileWidget2::recalcCeiling()
The ProfileWidget2::recalcCeiling() function is used in one place,
namely when an undo-command changes the mode. It recalculates
decompression data and repaints the ceilings and thus avoids a
full profile-redraw.

This is smart, but it becomes problematic when the dive is changed
and the ceiling is recalculated before the profile is redrawn.
The DivePlotDataModel then still has data from the previous dive
but cylinders of the new dive are accessed.

This kind of situation may arise if multiple dive fields are
updated, as for example when replanning a dive.

Currently, this only causes a temporary mis-calculation. When
removing MAX_CYLINDERS this will lead to crashes.

One might attempt to fix the whole data-dependency mess. This
commit goes the cheap route and simply redraws the profile when
the mode is changed. Yes, it is in a way ineffective, but we
do worse things. The ProfileWidget2::recalcCeiling() thus becomes
unused and is removed.

25b30da244 Profile: properly initialize plot_info structures
The create_plot_info_new() function releases old plot data. This

This turned out to be more cumbersome than expected: we don't

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.

43c3885249 Undo: isolate undo-commands
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
  appropriate Document class.

In commit bd0c99dfb7 (display pO2 and Setpoint for CCR dives)

While this seems reasonable, there is small group of mCCR
divers that do not log their po2 digitally, so the only po2
they can display is the setpoint that is reported by the used
DC. As this is a bit of a dull flat line, most of these
divers do not display this. And this leaves room on the
small mobile display for the temperature data.

Note that on common 64-bit platforms struct gasmix is the size

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

least of our worries.

Currently, get_gasmix_from_event() and get_gasmix() return pointers
to either static or to (possibly changing) dive data. This seems like
a dangerous practice and the returned data should be used immediately.

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
passed.

Since get_gasmix() now returns a value, the first invocation is
tested by a NULL-initialized "struct event *". Document this in
a comment.

c5f66c5538 Dive media: transport dive-id in drag'n'drop events
9efb56e2d4 introduced rather complex
logic for picture drag'n'drop events onto the profile. Among other
things, the code had to check whether the picture actually belongs
to the displayed dive.

This can be simplified by transporting the dive-id in the drag'n'drop
event structure. The flow goes like this:
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
was decoupled from DivePictureModel.

For (2), we simply replace the "position" value, which was never used.
Why would the receiver care which pixel was pressed in the media-tab?

This commit also contains a minor cleanup in DivePictureWidget:
QListView::mousePressEvent(event) was called in both branches of an
if and can therefore be removed from the if. This is so trivial,
that it doesn't warrant its own commit.

not work out, because on hoverEnter and hoverExit events, the z-values
were modified, thus restoring the wrong drawing order.

of the list.

Gracefully handle drag & drop to the profile, which changes the
offset of the pictures. To do this, keep the pictures in the
DivePictureModel and the ProfileWidget2 sorted by offset and
re-arrange if needed to keep the list sorted. This needs some
code reshuffling.

Introduce a helper-function that moves ranges in arrays.
