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>
2018-09-07Cleanup: constify get_units()Gravatar Berthold Stoeger
get_units() returns a pointer to the units struct in the preferences. Callers should not modify the preferences via this struct, therefore make the return value point to const. This is a small step in constifying the global preferences structure. 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: const-ify parameters to trivial accessor functionsGravatar Berthold Stoeger
Accessor-functions without noticeable logic, such as depth_to_bar() can trivially be made "const-clean". Moreover, let get_dive_location() return a "const char *". The non-const version must have been an oversight, as the caller must not free() or overwrite the string. 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>
2018-07-21Uninline functions in dive.hGravatar Berthold Stoeger
There were numerous inlined functions in dive.h. For many of them inlining is dubious. Let's uninline most of them, with the exception of trivial accessors and interpolate(). On current master, this gave a size reduction of 5 pages: -rwxrwxr-x 1 bs bs 5863656 Jul 18 20:57 subsurface-inline -rwxrwxr-x 1 bs bs 5843176 Jul 18 20:48 subsurface-noinline ----------------------------------------------------------- 20480 Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
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.

2018-07-18Cleanup: rename trip->index to trip->savedGravatar Berthold Stoeger

2018-07-17Cleanup: simplify dive_getUniqID()Gravatar Berthold Stoeger
dive_getUniqID() is used to create unique dive ids, which are stable during application lifetime. It was passed a dive, checked that the id was not set (if it was that it is know to the application) and set a new id (in contradiction to its name!) if it hadn't any. There were three callers: alloc_dive(): called the function on a zeroed dive struct. fixup_dive(): called the function only if the dive had a 0 id. MainWindow::setupForAddAndPlan(): called the function on a zeroed dive struct. Thus, in all three callers the id is guaranteed to be zero and the whole keeping-track-of-ids logic is moot. Remove the logic, don't pass a dive struct to dive_getUniqID() and move the function to the C-backend. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-07-07save-git: allocate user_info members on the heapGravatar Lubomir I. Ivanov
subsurface_user_info() only works on Linux (linux.c), but it doesn't allocate values on the heap. Solve this ownership problem by always allocating .name and .email on the heap in subsurface_user_info() and freeing in the caller. If subsurface_user_info() did not modify any of the values from NULL, use default ones, but allocate them on the heap too. Ref #1346 Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>

2018-06-20equipment: sanitize 'ws_info' loop limitsGravatar Lubomir I. Ivanov
Instead of a constant or a macro for the maximum number of 'ws_info' elements the 100 literal was used. Define MAX_WS_INFO in dive.h and use it everywhere. Also clamp loops that iterate `ws_info' to MAX_WS_INFO. Prevents potential out-of-bounds reading, similarly to the previous commit about 'tank_info'. Signed-off-by: Lubomir I.

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.

2018-05-14Read and write divemode changes (xml and git)Gravatar Willem Ferguson
This provides for reading of divemode change events from dive logs and for writing them to dive logs. This applies to xml and git divelogs. Divemode change events have the following structure: event->name = "modechange" event->value = integer corresponding to enum dive_comp_type (dive.c), reflecting the type of divemode change (OC, CCR, PSCR, etc). In the dive log file, the event value is written as a string that corresponds to each of the enum values, e.g. <event name='modechange' divemode='OC' /> This xml is also read from the dive log file and translated to an appropriate value of event->value. The file diveeventitem.cpp was udated to reflect this new way of dealing with divemode change events. Signed-off-by: Willem Ferguson <willemferguson@zoology.up.ac.za>

2018-05-14Simplify bailout events in the dive logGravatar Willem Ferguson
I removed the special event type that has been used for bailout events. Bailout events are now just bookmarks with a specific name "e.g. OC, CCR, PSCR). This removes a case where a segmentation error occurred when trying to remove a bailout event from the dive profile. Signed-off-by: Willem Ferguson <willemferguson@zoology.up.ac.za>
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>

2018-05-07Planner: don't return static data in fake_dc()Gravatar Berthold Stoeger
fake_dc() used to return a statically allocated dc with statically allocated samples. This is of course a questionable practice in the light of multi-threading / resource ownership. Once these problems were recognized, the parameter "alloc" was added. If set to true, the function would still return a statically allocated dc, but heap-allocated samples, which could then be copied in a different dc. All in all an ownership nightmare and a recipie for disaster. The returned static dc was only used as a pointer to the samples anyway. There are four callers of fake_dc() and they all have access to a dc-structure without samples. Therefore, change the semantics of fake_dc() to fill out the passed in dc. If the caller does not care about the samples, it can simply reset the sample number to zero after work. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2018-03-05Cleanup: Remove hash field from picture-structureGravatar Berthold Stoeger
The hash field in the picture-structure was in principle non-operational. It was set on loading, but never actually changed. The authoritative hash comes from the filename->hash map. Therefore, make this explicit by removing the hash field from the picture structure. Instead of filling the picture structure on loading, add the hash directly to the filename->hash map. This is done in the register_hash() function, which does not overwrite old entries. I.e. the local hash has priority over the save-file. This policy might be refined in the future.

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.
