2020-05-01cleanup: make analyze_plot_info local to profile.cGravatar Berthold Stoeger
No external caller of this function exists. Moreover, turn the return type to void, as it only returned the passed-in plot_info and no caller used that. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-05-01cleanup: const-ify a few functions in planner.cGravatar Berthold Stoeger
It make debugging much easier if the function signature tells you that a parameter is not altered. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-05-01profile: for maxtime calculation include the sample after the last eventGravatar Berthold Stoeger
When plotting profiles with surface segments, there were strange artifacts. As we found out with Robert, these were due to the fact that the calculated maxtime was set to the last event which is just one second inside the surface segment. This terribly confused the profile code. For example, it didn't properly allocate samples for the surface segment. Thus, when calculating maxtime, consider the last sample beyond the last event.

2020-04-20profile: avoid invalid accesses in setup_gas_sensor_pressureGravatar Berthold Stoeger
Since we removed MAX_CYLINDERS, we have the possibility of dives with no cylinders. In such a case, setup_gas_sensor_pressure() would do invalid read- and write-accesses. Therefore, return early in such a case. Reported-by: Chirana Gheorghita Eugeniu Theodor <office@adaptcom.ro> Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-04-18debug output: ensure our debug output is captured on AndroidGravatar Dirk Hohndel
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).

2020-04-18profile: avoid double-free when reusing plot_infoGravatar Berthold Stoeger
free_plot_info_data() freed the pressure-data, but didn't set the value to NULL. Thus, when the plot_info was reused, a double-free() could ensue. Crash condition: export the profiles of multiple dives with pressure data. Reported-by: Willem Ferguson <willemferguson@zoology.up.ac.za> Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-04-07cleanup: remove commented-out evn_foreach() functionGravatar Berthold Stoeger
Apparently this was used to hide events in pre-Qt times. However, that has already been reimplemented in different ways. Let's remove that commented-out code. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

Grammar-nazi ran git grep -l 'indexes' | xargs sed -i '' -e 's/indexes/indices/g' to prevent future wincing when reading the source code. Unfortunatly, Qt itself is infected as in QModelIndexList QItemSelection::indexes() const Signed-off-by: Robert C. Helling <helling@atdotde.de>
2019-11-28Add current GF to infoboxGravatar Robert C. Helling
As per request from users on scubaforum.com, this adds the current gradient factor to the deco information of the infobox. Up to now, this information was only graphically represented in the pressure bar graph and the heatmap. This gives a numerical value. Signed-off-by: Robert C. Helling <helling@atdotde.de>
2019-11-16Don't access uninitialized deco_structureGravatar Robert C. Helling
Coverty found that in the export functions, we initialize the planner deco state with NULL and then possibly later access its content. This makes sure, we don't do that.

2019-11-12Profile: fix pressure scaleGravatar Berthold Stoeger
The determination of minimum pressure in calculate_max_limits_new() in profile.c was wrong for a long time. Since the loop went over all cylinders (even unused ones), the minimum pressure was always zero. Since we loop only over used cylinders, the minimum pressure was initialized to the lowest starting pressure of any cylinder. If there were no events with pressure change, the minimum pressure stayed unchanged, resulting in a funky scaling. Instead, let's initialize the minimum pressure to the lowest ending pressure.

2019-11-09Cylinders: access cylinders with get_cylinder()Gravatar Berthold Stoeger
Instead of accessing the cylinder table directly, use the get_cylinder() function. This gives less unwieldy expressions. But more importantly, the function does bound checking. This is crucial for now as the code hasn't be properly audited since the change to arbitrarily sized cylinder tables. Accesses of invalid cylinder indexes may lead to silent data-corruption that is sometimes not even noticed by valgrind. Returning NULL instead of an invalid pointer will make debugging much easier.

2019-11-09Core: remove MAX_CYLINDERS restrictionGravatar Berthold Stoeger
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.

2019-11-09Profile: dynamically allocate gases arrayGravatar Berthold Stoeger
To calculate sac rates, an array of used gases for every point on the profile was used. This was implemented using unsigned int bitfields. While nobody sane will ever use 32 or even 64 cylinders, for consistency with the rest of the code, also change this to use dynamically allocated arrays. But allocate only once per shown profile, not once per sample. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-11-09Profile: dynamically allocate plot pressure dataGravatar Berthold Stoeger
All accesses to the pressure data were converted to use functions. Therefore it is now rather trivial to dynamically allocate the pressure array and just change the functions. The only thing to take care of is the idiosyncratic memory management. Make sure to free and copy the buffer in the appropriate places. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-11-09Profile: turn INSERT_ENTRY macro into helper functionGravatar Berthold Stoeger
The only apparent reason that this was a macro is that it automatically increased the "index" and "entry" counts. But incrementing these explicitly seems reasonable. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2019-11-09Profile: change get_plot_pressure to take index instead of pointerGravatar Berthold Stoeger
The goal here is to make it possible to detach the pressure related data from the plot_info structure. Thus, the pressure related data can be allocated independently depending on the number of cylinders per dive. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2019-08-28Profile: properly initialize plot_info structuresGravatar Berthold Stoeger
The create_plot_info_new() function releases old plot data. This can only work if the plot_info structure was initialized previously. The ProfileWidget2 did that by a memset, but other parts of the code did not. Therefore, introduce a init_plot_info() function and call that when generating a plot_info struct. Constructors would make this so much easier - but since this is called from C, we can't use them. Fixes #2251 Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2019-07-18Cleanup: replace pressure reading macros by inline functionsGravatar Berthold Stoeger
Replace the INTERPOLATED_PRESSURE and SENSOR_PRESSURE macros by inline functions. Generate a common inline function that reads a pressure value for a dynamic sensor. Not all SENSOR_PRESSURE macros can be replaced, because the macro is also used to set the value and C sadly doesn't know the concept of "return reference from a function".

2019-07-18Cleanup: turn GET_PRESSURE macro into inline functionGravatar Berthold Stoeger

2019-07-06Cleanup: call calculate_max_limits_new() in create_plot_info_new()Gravatar Berthold Stoeger
All callers of create_plot_info_new() called calculate_max_limits_new() a line before. Thus, simply call the latter in the former. This allows us to automatically free the plot data in create_plot_info_new(). The old code overwrote the corresponding field with NULL. As a side-effect, this removes a bogus static variable.

2019-07-06Cleanup: fix memory management of the plot dataGravatar Berthold Stoeger
There was a global variable last_pi_entry_new, which stored the recently allocated plot data. This was freed when new plot data was generated. A very scary proposition: You can never have two plot datas at the same time! But exactly that happens when you export for example subtitles. The only reason why this didn't lead to very crazy behavior is that at least on my Linux machine, the calloc() call would just return the previously freed memory. Fix this mess by removing the global variable and freeing the data in the callers. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2018-10-11Undo: select dives after add, remove, merge, split dive commandsGravatar Berthold Stoeger
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.

2018-09-10Profile: fix SAC calculation for air divesGravatar Berthold Stoeger
Commit f5b11daffd6f240268ce78d72c64be43670988ea changed gasmix arguments and return values to be passed by value instead of using pointers. Notably, get_gasmix() is fed a default-value and returns a new value. In the old code, NULL was passed in in a first loop iteration and non-NULL was always returned in the first iteration. Thus, an equality comparison of passed-in an returned gasmix would always fail in the first loop iteration. The new code passed in air as default. Now if air was also returned, then the matching gases were not calculated in calculate_sac(). To revert to the old behavior, pass in an invalid gasmix. Moreover, give names to the invalid and air gasmixes. Reported-by: tormento <turment@gmail.com> Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-08-23Cleanup: const-ify functions taking pointers to eventsGravatar Berthold Stoeger
This is another entry in the series to make more things "const-clean" with the ultimate goal of merge_dive() take const pointers. This concerns functions taking pointers to events and the fallout from making these const. The somewhat debatable part of this commit might be that get_next_event() is split in a two distinct (const and non-const) versions with different names, since C doesn't allow overloading. The linker should recognize that these functions are identical and remove one of them. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-08-23Cleanup: pass gasmix by valueGravatar Berthold Stoeger
In a previous commit, the get_gasmix_* functions were changed to return by value. For consistency, also pass gasmix by value. Note that on common 64-bit platforms struct gasmix is the size of a pointer [2 * 32 bit vs. 64 bit] and therefore uses the 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 invasive change that going back to pointers is probably the least of our worries. This commit is a step in const-ifying input parameters (passing by value is the ultimate way of signaling that the input parameter will not be changed [unless there are references to said parameter]).

2018-08-23Cleanup: return gasmix by valueGravatar Berthold Stoeger
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. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2018-05-14Implement bailout outside of the dive plannerGravatar Willem Ferguson
This is the second step for implementing bailout. The indirect calls to fill_pressures through add_segment() (in deco.c) are addressed. Bailout is now fully implemented in the dive log but not in the dive planner. 1) The parameters to add_segment() are changed to take a divemode as the second last parameter, and not a *dive. 2) Call to add_segment() in profile.c and in divelist.c are adapted. In divelist.c some calls to add_segment were left using dc-> divemode instead of possible bailout. This appears tp be the most appropriate route. 3) The functions get_divemode_from_time() and get_next_divemodechange() in dive.c have had some small changes. 4) The calls to get_segment(0 in planner.c were changed to reflect the new parameter list, but not updated to reflect bailout. This is the next step. Signed-off-by: Willem Ferguson <willemferguson@zoology.up.ac.za>
2018-05-14Incorporate bailout events in CCR & PSCR gas calculations.Gravatar Willem Ferguson
This is a first step to interpret bailout events. 1) The event structures have a new attribute: divemode. Currently interpreted dive modes are OC, CCR, PSCR. 2) When doing fill_pressures(), the calculation is aware of divemode. When divemode is OC (==bailout), then the appropriate calculations of gas pressures are done. 3) Two new functions get_next_divemodechange() and get_divemode_at_time() are created to find divemode changes in the events linked list and to determine the dive mode at any point during the dive. 4) fill_pressures gets a small amendment to facilitate the correct calculations, depending on divemode. The cases where fill_pressures() is used *outside the planner* are changed. The result is that, for dives with bailout, the correct gas pressures are shown on the dive profile. The deco for bailout dives is not yet correct. This is the next step. Signed-off-by: Willem Ferguson <willemferguson@zoology.up.ac.za>
