The TeX exports may hang the UI for a long time.
Show a progress-dialog that is updated after every exported dive
and allows the user to cancel the export.
This is pretty lame, because it is synchronous (export still runs
in UI thread) and therefore the UI still is sluggish. But it
is an improvement.
Since the TeX-exporting code is in a shared directory (desktop and
mobile), this uses a slim interface class. Mobile does not
yet use TeX export, but you never know. Better than #ifdefs
sprinkled all around, I reckon.

When creating the context menu, a special menu is created for

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

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.

It looks like libxml2 has some internal limitations by default that

I don't know libxml2 internals, so I have no idea what exactly goes

XML_PARSE_HUGE = 524288 : relax any hardcoded limit from the parser

The code assumes that prefs.cloud_base_url is non NULL. Allowing that to
be NULL makes no sense during normal operation of the app. Yet, most of
the tests don't initialize the prefs at all.
Making things worse, if we do correctly initialize the prefs (so as to
reasonably approximate the behavior when running the app), things break
because some of the reference outputs assume that the prefs are unset.
This deserves fixing.
For now, simply make sure that cloud_base_url is set for all the tests
that try to parse files.
Additionally, the semantics how cloud_base_url is saved to disk have
changed, so adjust the test for those prefs accordingly.

With the new names for the cloud server we'd get different local cache

that, normalize the name before generating the hash that determines the

Additionally, the old code had an extra '/' in the URL, due to the way
the URL was assembled. Again, to match the existing hash for people
upgrading from older Subsurface versions, add that to our normalized

The backend infrastructure will soon be able to support more than one
cloud server which automagically stay in sync with each other.
One critical requirement for that to work is that once a session was
started with one of the servers, the complete session happens with that
server - we must not switch from server to server while doing a git
transaction. To make sure that's the case, we aren't trying to use DNS
tricks to make this load balancing scheme work, but instead try to
determine at program start which server is the best one to use.
Right now this is super simplistic. Two servers, one in the US, one in
Europe. By default we use the European server (most of our users appear
to be in Europe), but if we can figure out that the client is actually
in the Americas, use the US server. We might improve that heuristic over
time, but as a first attempt it seems not entirely bogus.
The way this is implemented is a simple combination of two free
webservices that together appear to give us a very reliable estimate
which continent the user is located on.
api.ipify.org gives us our external IP address
ip-api.com gives us the continent that IP address is on
If any of this fails or takes too long to respond, we simply ignore it
since either server will work. One oddity is that if we decide to change
servers we only change the settings that are stored on disk, not the
runtime preferences. This goes back to the comment above that we have to
avoid changing servers in mid sync.

When showing the "empty-state", the profile toolbar was

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.

There are two cases in this function: with and without holding
the control-key. The former deletes one point, the latter all
points starting with the selected point to the end.
The code was interlaced making it very hard to reason about.
Notably, it was buggy: with control, all points could be
deleted, leading to a crash.

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.

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

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.

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.

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;

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.

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.

MainTab::updateDiveInfo() is not executed when in the planner.
To decide whether the application is in the planner state,
it queried the profile. Instead, query the DivePlannerPointsModel.
Currently, there is no autoritative carrier of that flag.
However, the MainTab has a dependency on DivePlannerPointsModel
anyway, and therefore this removes a dependency on the
profile. This brings us closer to a state where we can have
multiple profiles.
