2019-06-28Planner: Wait minimum switch time when bailing out to OCGravatar Robert C. Helling
Bailing out does not happen instantly. Rather wait for the minimum stop switch duration before ascending. Signed-off-by: Robert C. Helling <helling@atdotde.de>

2019-01-13Planner: Add checkbox to force OC bailoutGravatar Robert C. Helling
This adds a checkbox for rebreather modes of the planner that force the ascent to be in OC mode. Before, one had to add a one minute last segment with the mode change but this is not practical when manually searching for the maximal bottom time given gas reserves. Signed-off-by: Robert C. Helling <helling@atdotde.de>
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]). Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
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>

2018-06-20equipment: sanitize 'tank_info' loop limitsGravatar Lubomir I. Ivanov
In a number of places the global 'tank_info' array is being iterated based on a 'tank_info[idx].name != NULL' condition. This is dangerous because if the user has added a lot of tanks, such loops can reach 'tank_info[MAX_TANK_INFO]'. This is an out of bounds read and if the 'name' pointer there happens to be non-NULL, passing that address to a peace of code that tries to read it (like strlen()) would either SIGSEGV or have undefined behavior. Clamp all loops that iterate 'tank_info' to MAX_TANK_INFO. Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>

2018-05-14Adapt the dive planner to do bailoutGravatar Willem Ferguson
Ensure that calls to add_segment() all have a appropriate divemode for that part of the dive plan. In the case of plan(), the existing variable 'divemode' was directly passed to add_segment. For the functions interpolate_transition() and trial_ascent(), the divemode was obtained by including it in the parameter list of the function and divemode supplied by the calling function. Signed-off-by: Willem Ferguson <willemferguson@zoology.up.ac.za>
2018-05-14Add planner infra structure for bailoutGravatar Robert C. Helling

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>

2018-05-07Planner: Unify final ascent rates in plan() and fake_dc()Gravatar Berthold Stoeger
When generating fake profiles for manually entered dives, fake_dc() and plan() used different final ascent rates of 5 m/min and 4.5 m/min, respectively. This led to dives that were 6 seconds longer than entered by the user and to confusion. See #554. Therefore, use the same ascent rate taken from the preferences field flag.ascratelast6m in both cases. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-02-26Cleanup: Unify qthelper.h and qthelperfromc.hGravatar Berthold Stoeger
Since all qt-helpers are defined in qthelper.cpp, there seems to be no reason to have two include files. By unifying the two files, duplication and inconsistencies are removed. The C++-only part is simply compiled away with #ifdefs. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2018-01-19Improve profile display in plannerGravatar Willem Ferguson
This patch allows the planner to save the last manually-entered dive planner point of a dive plan. When the plan has been saved and re-opened for edit, the time of the last-entered dive planner point is used to ensure that dive planning continues from the same point in the profile as was when the original dive plan was saved. Mechanism: 1) In dive.h, create a new dc attribute dc->last_manual_time with data type of duration_t. 2) In diveplanner.c, ensure that the last manually-entered dive planner point is saved in dc->last_manual_time. 3) In save-xml.c, create a new XML attribute for the <divecomputer> element, named last-manual-time. For dive plans, the element would now look like: <divecomputer model='planned dive' last-manual-time='31:17 min'> 4) In parse-xml.c, insert code that recognises the last-manual-time XML attribute, reads the time value and assigns this time to dc->last_manual_time. 5) In diveplannermodel.cpp, method DiveplannerPointModel::loadfromdive, insert code that sets the appropriate boolean value to dp->entered by comparing newtime (i.e. time of dp) with dc->last_manual_time. 6) Diveplannermodel.cpp also accepts profile data from normal dives in the dive log, whether hand-entered or loaded from dive computer. It looks like the reduction of dive points for dives with >100 points continues to work ok. The result is that when a dive plan is saved with manually entered points up to e.g. 10 minutes into the dive, it can be re-opened for edit in the dive planner and the planner re-creates the plan with manually entered points up to 10 minutes. The rest of the points are "soft" points, shaped by the deco calculations of the planner. Improvements: Improve code for profile display in dive planner This responds to #1052. Change load-git.c and save-git.c so that the last-manual-time is also saved in the git-format dive log. Several stylistic changes in text for consistent C source code.

2017-12-17Unify float calulations: use doubleGravatar Berthold Stoeger
Internal floating point (FP) calculations should be performed using double unless there is a very good reason. This avoids headaches with conversions. Indeed, the vast majority of FP calculations were already done using double. This patch adapts most remaining calculations. Not converted where things that were based on binary representations and variables which weren't used anyway. An analysis of all instances follows: core/plannernotes.c, l.404: This was a comparison between two floats. On the left side, first an integer was cast to float then multiplied with and integer and divided by a constant double. The right hand side was an integer cast to a float. Simply divide by 1000.0 first to convert to double and continue with calculations. On the right hand side, remove the cast, because the integer will be implicitely cast to double for comparison. This conversion actually emits less instructions, because no conversion to double and back is performed. core/planner.c, l.613: Same analysis as previous case. subsurface-desktop-main.cpp, l.155: A local variable representing the version OpenGL version. Turn this into integer logic. Not only does this avoid dreaded FP rounding issues, it also works correctly for minor version > 10 (not that such a thing is to be expected anytime soon). abstractpreferenceswidget.[h/cpp]: A widget where the position is described as a float. Turn into double. desktop-widgets/divelogexportdialog.cpp, l.313: total_weight is described as float. Use double arithmetics instead. This instance fixes a truncation warning emitted by gcc.

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>

2017-11-08VPMB: calculate deco_time assuming final ascent always takes the same timeGravatar Rick Walsh
If we consider the actual time to ascend from the final stop when calculating deco_time, then slowing the final ascent can lead to the final stop being extended, which is completely nonsensical. For consistency with the original VPMB implementation, we can't ignore the final ascent time completely, but if we assume it is always the same (take default ascent rate of 9m/min) then slower the final ascent won't lead to a longer final stop.
