2018-09-23Core: split process_dives() in post-import and post-load versionsGravatar Berthold Stoeger
process_dives() is used to post-process the dive table after loading or importing. The first parameter states whether this was after load or import. Especially in the light of undo, load and import are fundamentally different things. Notably, that latter should be undo-able, whereas the former is not. Therefore, as a first step to make import undo-able, split the function in two versions and remove the first parameter. It turns out the the load-version is very light. It only sets the DC nicknames and sorts the dive-table. There seems to be no reason to merge dives. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
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 dives and divecomputersGravatar Berthold Stoeger

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: unify get_gas_at_time() and get_gasmix()Gravatar Berthold Stoeger
There were two functions for getting gas-mixes at a certain timestamp: - get_gasmix() for repeated queries. - get_gas_at_time() for a single query. Since the latter is a special case of the former, simply call the former in the latter. Moreover, rename to get_gasmix_at_time() for consistency. Replace on get_gasmix() call, which was outside of a loop by the corresponding get_gasmix_at_time() call. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
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>
2018-08-02Cleanup: move sort_table() from subsurface_startup.c to divelist.cGravatar Berthold Stoeger

2018-07-19Undo: remember deleted trip in UndoRemoveDivesFromTrip::undo()Gravatar Berthold Stoeger
If the last dive of a trip is removed, the trip is deleted. On redo the dive is added to a non existing trip, leading to a segfault. Therefore, keep a copy of the trip to reinstate it on redo. Note: this cannot work for a sequence of multiple commands. One would have to rewrite the whole undo-history. Nevertheless, let's do this as a stop-gap measure.

2018-05-28Don't compute SAC if total gas use is unknownGravatar Robert C. Helling
If we breathe from a cylinder with invalid start or end pressures, we cannot reliably compute the total gas use and thus the SAC. So we should not pretend to do so.

2018-05-14Implement get_divemode() to find the divemode at a particular timeGravatar Willem Ferguson
Replaced a rather cumbersome function that that did the above. Upon the suggestion of Robert Helling who proposed a much shorter way, this new function replaced the previous ones. This necessitated changes to divelist.c, profile.c and plannernotes.c, as well as dive.c/h. Signed-off-by: Willem Ferguson <willemferguson@zoology.up.ac.za>
2018-05-14Simplify the bailout detection functions.Gravatar Willem Ferguson

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>

This is the only case where C-code sets the current file. Remove this call for a better separation of C-backend and C++-frontend parts. There were four callers of clear_dive_file_data(). Two of them would call set_filename() anyway. For the remaining two add an explicit call to set_filename().

2017-11-25Localize global planner stateGravatar Robert C. Helling
For UI responsiveness, we need to be able to run the planner in the background. This needs the planner state to be localized (and we need to pass a pointer around). In order to not let too many lines overrun (and to save typing in the future) I have renamed instances of struct deco_state to ds. Yes this should have gone to a separate commit but I accidentally commit --amend'ed it. Computing of planner variations is temporarily disabled. Unlock the planner when returning early So we don't deadlock in add dive and recreational mode (which use the planner without actually planning). Signed-off-by: Robert C. Helling <helling@atdotde.de>

2017-10-18init_deco correctly identify previous dives and report overlapping divesGravatar Stefan Fuchs
When changing the date/time of a dive in the planner the dive may end up in a totaly new position in respect to date/time of other dives in dive list table. It can be moved to the past or the future before or after other existing dives. It also could overlap with an existing dive. This change enables identification of a new "virtual" dive list position and based on this starts looking for previous dives. Then it (as before the change) does init the deco calculation with any applicable previous dive and surface interval. If some of these applicable dives overlap it returns a neg. surface time which is then used in the planner notes to prohibit display of results. Signed-off-by: Stefan Fuchs <sfuchs@gmx.de>

2017-07-28Use the right gasmix for deco calculationsGravatar Linus Torvalds
In commit e1b880f4 "Profile support for multiple concurrent pressure sensors" I had mindlessly hacked away at some of the sensor lookups from the plot entries to make it all build, and forgotten about my butchery. Thankfully Jan and Davide noticed in their multi-cylinder deco dives that the deco calculations were no longer correct. This uses the newly introduced "get_gasmix()" helper to look up the currently breathing gasmix, and fixes the deco calculations.

2017-07-21Start cleaning up sensor indexing for multiple sensorsGravatar Linus Torvalds
This is a very timid start at making us actually use multiple sensors without the magical special case for just CCR oxygen tracking. It mainly does: - turn the "sample->sensor" index into an array of two indexes, to match the pressures themselves. - get rid of dive->{oxygen_cylinder_index,diluent_cylinder_index}, since a CCR dive should now simply set the sample->sensor[] indices correctly instead. - in a couple of places, start actually looping over the sensors rather than special-case the O2 case (although often the small "loops" are just unrolled, since it's just two cases. but in many cases we still end up only covering the zero sensor case, because the CCR O2 sensor code coverage was fairly limited. It's entirely possible (even likely) that this migth break some existing case: it tries to be a fairly direct ("stupid") translation of the old code, but unlike the preparatory patch this does actually does change some semantics. For example, right now the git loader code assumes that if the git save data contains a o2pressure entry, it just hardcodes the O2 sensor index to 1. In fact, one issue is going to simply be that our file formats do not have that multiple sensor format, but instead had very clearly encoded things as being the CCR O2 pressure sensor. But this is hopefully close to usable, and I will need feedback (and maybe test cases) from people who have existing CCR dives with pressure data.

This is important to not duplicate code for the Qml view. Now the DownloadFromDiveComputer widget is mostly free from important code (that has been upgraded to the core folder), and I can start coding the QML interface. There are still a few functions on the desktop widget that will die so I can call them via the QML code later.

2016-04-29Extend time parsing to before 1970Gravatar Linus Torvalds
It turns out that we are starting to have users that have logs that go back that far. It won't be common, but let's get it right anyway. NOTE! With us now supporting dates earlier in 1900, this also makes "utc_mktime()" always add the "1900" to the year field. That way we avoid ever using the fairly ambiguous two-digit shorthand. It didn't use to be all that ambiguous when we knew that any two-digit number less than 70 had to be 2000+. Now that we support going back to earlier in the last centiry, that certainty is eroding.

2016-04-14Add helper to find the dive closest to a given timeGravatar Dirk Hohndel
If we want to keep the selected dive "close" to where it was before an operation (whether a delete, or a reload, or something like that), then the most intuitive thing to do appears to be to select either the same dive again (if it still exists), or one very close to it in time. This helper allows us to identify the dive in the current dive list that is closest to the given time. We do this in the C code to ensure that we look at all dives in the dive_table - based on the id that is returned the UI can then figure out where this dive is currently shown.

Having subsurface-core as a directory name really messes with autocomplete and is obviously redundant. Simmilarly, qt-mobile caused an autocomplete conflict and also was inconsistent with the desktop-widget name for the directory containing the "other" UI.
