2020-05-01core: create fake cylinder at end of cylinder table (hack!)Gravatar Berthold Stoeger
When we had fixed-sized cylinder arrays, the planner used the last empty cylinder for "surface air". This was not recognized by the UI as a separate cylinder, because "empty cylinder" was the sentinel for the end of the table. The conversion to dynamically sized cylinder tables broke this code: everytime the surface segment is changed, a new dummy cylinder is added, which is visible in the UI. As a very temporary stop-gap fix, emulate the old code by creating a cylinder and then setting the end-of-table to before that cylinder. This means that we have to loosen the out-of-bound checks. That's all very scary and should be removed as soon as possible. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-04-20core: return -1 from explicit_first_cylinder() if dive has no cylindersGravatar Berthold Stoeger
Arguably, returning 0 for a dive with no cylinders is wrong, since the 0 is a valid cylinder id, however that cylinder doesn't exist. Instead, return -1. All callers of explicit_first_cylinder() return early anyway for dives with no cylinders. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-04-13Preserve events when editing dive in plannerGravatar Robert C. Helling
The planner does not know about events except gas changes. But if the dive comes from the log, we should preserve the dive computer events. At least those that happend before we started to delete waypoints to let the planner take over. Signed-off-by: Robert C. Helling <helling@atdotde.de>
2020-04-11media: invalidate correct dive when removing pictureGravatar Berthold Stoeger

2020-04-07undo: implement renaming of eventsGravatar Berthold Stoeger
There is a slight complexity here owing to the fact that the profile works on a copy of the current dive: We get a copy of the event and have to search for the original event in the current dive. This could be done in the undo command. Nevertheless, here we do it in the profile so that when in the future the profile can work on a non-copied dive we can simply remove this function.

2020-04-07core: add remove_event_from_dc() functionGravatar Berthold Stoeger
We have a remove_event() function that 1) frees the event 2) works on the current divecomputer 3) compares the events because the profile has copies of events However, for undo commands 1) we want to keep the event so that we can readd it later 2) we have to work on arbitrary divecomputers 3) we don't work with copies of events Therefore, create a new remove_event_from_dc() function that does all that. Moreover, make the event argument to remove_event() const to (slightly) point out the difference in the API. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-04-07core: split add_event() in two partsGravatar Berthold Stoeger
add_event() creates and adds an event from the given parameters. For undo, we want to do these separately, therefore split this function in two parts: create_event() and add_event_to_dc(). Keep the add_event() function for convenience. Moreover, keep the remember_event() call in there, so that undo-commands can call remember_event() once, not on every undo/redo action.

2020-03-06Core: don't return invalid cylinders from explicit_first_cylinder()Gravatar Berthold Stoeger
For reasons which I don't yet understand, when plotting a dive whose first cylinder is not cylinder 0 and then plotting a dive with only one cylinder, it can happen that for the latter explicit_first_cylinder() returns an erroneous value. This is due to the way in which we copy the dive to be plotted to displayed_dive. For now, make sure that no invalid cylinder is returned to avoid crashes. This will have to be changed anyway, since this is very fundamentally not thread-safe and inefficient. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

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.

2019-11-09Desktop: support no-cylinders in dive information tabGravatar Berthold Stoeger
The tab was crashing if there were no cylinders because 1) per_cylinder_mean_depth() would access non-existing cylinders. 2) TabDiveInformation::updateProfile() would access a non-existing mean. Fix both of these crash conditions by checking whether the dive actually has cylinders. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

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.

2019-11-09Core: create copy_cylinder_type() functionGravatar Berthold Stoeger

2019-11-09Core: dynamically allocate cylinder maps in merge_cylinders()Gravatar Berthold Stoeger
merge_cylinders() used three bitmaps to identify cylinders used in the first and second dive and matched cylinders.

2019-07-27Core: split copy_cylinders() in two functionsGravatar Berthold Stoeger
copy_cylinders() copied the cylinders of one dive onto another dive and then reset to the original gas values. Presumably, when copy and pasting cylinders from one dive to another, only the types should be copied, not the gases. Moreover, the function could either copy all or only the used cylinders. Firstly, the code was bogus: when restoring the pressures the indices were mixed up: the old indices were used. Thus, when there where uncopied cylinders, not all pressure values were restored. Secondly, it is not clear that all callers actually want to restore the pressure data. It rather appears the two (out of three) callers actually just want to copy the cylinders. Therefore, split the function in 1) copy_cylinders(): copy the cylinders with pressure data 2) copy_cylinder_types(): copy only the cylinder information Since there is only one caller of copy_cylinder_types(), the "used_only" argument can be removed. Since all cylinders are copied there is no point in storing the pressure data. Don't overwrite it in the first place. The resulting two functions should be distinctly easier to understand.

2019-07-19Cleanup: remove bogus mark_divelist_changed() callsGravatar Berthold Stoeger
The parsers / downloaders parse into a separate table and do not directly change the divelist. Therefore, they shouldn't call mark_divelist_changed(). Likewise split_dive_at() doesn't modify the dive list and therefore shouldn't call this function. Calling the function has the unwanted side-effect that undoing the change will not clear the *-symbol in the title of the main window. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-07-18Core: dynamically resize weight tableGravatar Berthold Stoeger
Replace the fixed-size weightsystem table by a dynamically relocated table. Reuse the table-macros used in other parts of the code. The table stores weightsystem entries, not pointers to weightsystems. Thus, ownership of the description string is taken when adding a weightsystem. An extra function adds a cloned weightsystem at the end of the table. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2019-07-14Fix cylinder gas type saving when we have bogus gas use dataGravatar Linus Torvalds
Steve Williams reported a crash when saving a previously loaded dive as xml, and gave a gdb backtrace. It turns out that if we can't parse the cylinder use type (OC, diluent, oxygen, unused) we initialize the cylinder use to an invalid type, and then when we save it, we mess up. Fix it up by doing proper limit checking before accessing the "cylinderuse_text[]" array when saving.
