2021-01-20cleanup: make a few DivePlannerModel functions privateGravatar Berthold Stoeger
It simplifies reasoning about control flow a lot if it is known that functions can't be invoked from a different part of the code base. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2021-01-20cleanup: remove dive parameter from DivePlotDataModel::setDive()Gravatar Berthold Stoeger
This was not used, probably an artifact from days long gone. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2021-01-20planner: remove DivePlannerPointsModel::startTimeChanged signalGravatar Berthold Stoeger
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.

2021-01-13mobile/cleanup: reduce the noise in our logsGravatar Dirk Hohndel
There are two sets of messages that tend to dominate the logs - the RSSI updates from the Qt BLE stack - the warnings about deprecated signal use in Kirigami Neither of them provide any value to us when trying to find bugs; and often they end up hiding the things that we really care about. So let's just not log them - which is easy as we have our own message handler. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2021-01-10profile: pass dive to DiveHandlerGravatar Berthold Stoeger
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. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2021-01-10profile: explicitly update profile itemsGravatar Berthold Stoeger
Instead of listening to the dive-data-model changed and axis changed signals, update the profile items explicitly once per plot() call. This avoids double replotting of the dive items. The old code had at least two replots per plot() call: one after profileYAxis()->setMaximum() and one after dataModel->emitDataChanged(). Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2021-01-10cleanup: const-ify DivePlotDataModel::*max() functionsGravatar Berthold Stoeger
These functions return the maximum partial pressures in the given dive. Obviously, being pure accessors, they should be const. This commit also replaces the macro generating these functions by a call to a function taking a pointer-to-member. Arguably, C++'s pointer-to-member syntax is just as horrible as macros, but at least it doesn't mess with syntax highlighting of my editor and should be better to debug. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2021-01-10profile: remove redundant code in DiveCalculatedCeilingGravatar Berthold Stoeger
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.

2020-12-29cleanup: remove getDivesInTrip() in qthelper.cppGravatar Berthold Stoeger
This function was not used anywhere. Moreover, remove a few unused includes from qthelper.h. Surprisingly, a number of users of qthelper.h depend on these, so readd them at the appropriate places. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2020-12-29filter: move shown_dive from divelist.c to divefilter.cppGravatar Berthold Stoeger
Arguably, the number of filtered dives is a matter of the divefilter. Let's move it there. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-12-29filter: reset shown_dives in filterGravatar Berthold Stoeger
The shown_dives variable was reset by the dive_list code. Arguably, the filter should keep track of the number of shown dives, so move the resetting there. This means adding a new "reset()" member function to the filter and call that instead of "updateAll()" when the core data is reset. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-12-17mobile: remove DiveObjectHelper codeGravatar Berthold Stoeger
When editing a dive, a DiveObjectHelper of the unmodified dive was created to compare the edited with the old values. Since the DiveObjectHelper is used here only as a pointless wrapper around the formatting functions, call these functions directly. However, note that the code is in principle wrong since the change to the mobile-models, which do not use the DiveObjectHelper. The real fix would be to reload the data from the model to prevent going out-of-sync with respect to the formatting routines! Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-12-17printing: remove DiveObjectHelper from printing codeGravatar Berthold Stoeger
At this point (post grantlee), DiveObjectHelper is just pointless glue code. Let's remove it from the printing code and call the formatting functions directly. If necessary, move these functions to core/string-format.cpp. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-12-17core: create string-format.cpp source fileGravatar Berthold Stoeger
The mobile version of the list used string formatting functions defined in DiveObjectHelper and declared in mobilelistmodels.h. Very confusing. Move them to a separate source file where - in the long run - all the string-formatting functions, which are scattered all over the place, can be collected.

2020-12-13core: keep tank infos in a dynamic tableGravatar Berthold Stoeger
The list of known tank types were kept in a fixed size table. Instead, use a dynamic table with our horrendous table macros. This is more flexible and sensible. While doing this, clean up the TankInfoModel, which was leaking memory. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-12-12preferences: create global settingsChanged signalGravatar Berthold Stoeger
So far, the PreferencesDialog emitted a settingsChanged signal. This meant that models that listened to that signal had to conditionally compile out the code for mobile or the connection had to be made in MainWindow. Instead, introduce a global signal that does this and move the connects to the listeners to remove inter-dependencies. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2020-11-24cylindermodel: remove in_planner() useGravatar Berthold Stoeger
in_planner() is problematic, since it is uses desktop-only application state. Since the cylinder-model already has an appropriate inPlanner flag, use this instead. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-11-24diveplannermodel: replace in_planner() by isPlanner()Gravatar Berthold Stoeger
The in_planner() function is problematic, because it depends on the application state that is only available on desktop. If we ever want to port the planner to mobile, we have to get rid of it. Luckily, the DivePlannerModel already has an appropriate flag that can be used instead. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-11-14desktop: automatically reload completion-modelsGravatar Berthold Stoeger

2020-11-14cleanup: remove macros from qt-models/completionmodels.cppGravatar Berthold Stoeger
There were macros to auto-generate functions to reload the models. One was only used once and therefore is pointless. The other can be replaced by a function with a pointer-to-member-variable argument. While doing this, adapt the coding style. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-11-07desktop: fix saving of column-widths of device and site tablesGravatar Berthold Stoeger
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.

2020-10-25cleanup: split out divecomputer functions from dive.cGravatar Berthold Stoeger
Since dive.c is so huge, split out divecomputer-related functions into divecomputer.[c|h], sample.[c|h] and extradata.[c|h]. This does not give huge compile time improvements, since struct dive contains a struct divecomputer and therefore dive.h has to include divecomputer.h. However, it make things distinctly more clear.

2020-10-25devices: connect DiveComputerModel to undo-commandGravatar Berthold Stoeger
Instead of modifying the device table directly, call the undo commands. Moreover, don't keep our own copy in the mode - show the original version. Connect to the appropriate signals. This means that the calls from the DiveComputerManagement dialog have to be removed, since this mode of editing is not supported. The whole dialog will be removed in a future commit. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-10-25models: update DiveComputerModel when core data is resetGravatar Berthold Stoeger
To implement undo-semantics, we want a longer-lived dive-computer-model (currently, it is regenerated when the dialog is opened). Therefore, it must be reloaded when the core data is reset. Do this like for other models: listen to the dataReset() signal of DiveListNotifier. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-10-25desktop: add tab-widget for dive computer namesGravatar Berthold Stoeger
If we want to include dive computer names in the undo system, there should be visual feedback on undo/redo. This would mean opening the divecomputer dialog, which would appear quite strange. Therefore, add a tab. This is not ideal, but consistent with the dive site tab, which probably shouldn't be there either. In the future, the UI needs some rethinking.

2020-10-24divecomputer: add device_table pointer to device_data_tGravatar Berthold Stoeger
In one weird case (suunto), the code in libdivecomputer.c generates a device node directly instead of going the usual way (setting the data in the dc-structure of the imported 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.

2020-10-24devices: add devices in Command::importTable()Gravatar Berthold Stoeger
Add a device_table parameters to Command::importTable() and add_imported_dives(). The content of this table will be added to the global device list (respectively removed on undo). This is currently a no-op, as the parser doesn't yet fill out the device table, but adds devices directly to the global device table. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-10-16cleanup: use std::vector in struct device_tableGravatar Berthold Stoeger
Since we converted from QString to std::string, let's also use std::vector instead of QVector. We don't need COW semantics and all the rigmarole. Let's try to keep Qt data structures out of the core. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-10-16cleanup: use std::string in struct deviceGravatar Berthold Stoeger
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.

2020-10-11desktop: make divecomputer table sortableGravatar Berthold Stoeger
Add a small proxy-model on top of DiveComputerModel so that clicking on table headers makes the table sortable. The UI feature here is not as important as the fact that the UI does its own sorting and we can keep the device-table in the core sorted differently. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-10-03cleanup: make device code more consistent with coreGravatar Berthold Stoeger
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.

2020-10-03dive list: when moving dives, delete first and add laterGravatar Berthold Stoeger
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. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-10-03cleanup: use getDiveSelection() to loop over selected divesGravatar Berthold Stoeger

2020-10-03cleanup: replace get_trip_date_string() by get_trip_string()Gravatar Berthold Stoeger
The get_trip_date_string() formatted, as the name implies, the date of a trip. It was passed a number of parameters and had only one caller, which would also add the location if it existed.

2020-09-29filter: add filter constraint modelGravatar Berthold Stoeger
Add a model that keeps track of a list of filter constraint and makes them accessible from Qt.

2020-09-29Use correct pO2 when computing MOD in equipment tabGravatar Robert C. Helling
The cylinder model is used both in the planner and the equipment tab. We have three preferences for the pO2 that is used to compute MOD: In the planner, there is one for the bottom part of the dive and another one for deco. Those are set in the planenr UI. There is another value, controlled in the Tec Prefernces. That one should be used in the equipment tab rather than the one from the planner. Fixes #2984 Signed-off-by: Robert C.

2020-09-27mobile/dive-list: correctly update view when changing dive dateGravatar Dirk Hohndel
If the dive timestamp changes, the dive could move in the dive list. But the current dive actually doesn't change (it's still the same dive, right?). Yet we need to update the dive list as well as the shown dive (especially if this is after adding a dive, which is first inserted with the current time and then updated with whatever the user enters).

2020-09-20dive list: on reload update filter statusGravatar Berthold Stoeger
At some time, when introducing the global reset signal the filter stopped being reloaded when loading a new log. This leads to very strange UI behavior: dives disappear when editing fields unrelated to the filter. Therefore, when reloading the model, reset the filter. One might argue whether this is the correct place. On the other hand, we might even make the filter a sub-object of the dive-list model. Let's think about this.

2020-09-13cleanup: fold core/divecomputer.cpp into core/device.cGravatar Berthold Stoeger
core/device.h was declaring a number of functions that were related to divecomputers (dcs): creating a fake dc for manually entered dives and registering / accessing dc nicknames. On could argue whether these should be lumped together, but it is what it is. However, part of that was implemented in C++/Qt code in a separate core/divecomputer.cpp file. Some function therein where only accessible to C++ and declared in core/divecomputer.h. All in all, a big mess. Let's simply combine the files and conditionally compile the C++-only functions depending on the __cplusplus define. Yes, that means turning device.c into device.cpp. A brave soul might turn the C++/Qt code into C code if they whish later on. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
