2019-06-19Coding style: remove Java-style function definitions in dive.cGravatar Berthold Stoeger
These stuck out like a sore thumb - let's go C-style instead. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-06-19Cleanup: remove unused function dump_taglist()Gravatar Berthold Stoeger
This was probably used for debugging but has no callers anymore. Let's remove it. If needed, it can be trivially readded. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-05-20Core: let count_divecomputers() operate on an arbitrary diveGravatar Berthold Stoeger
Currently, count_divecomputers only works on the current_dive. Instead, let it take a pointer to an arbitrary dive. This is in preparation for being smarter in the undo code concerning which dive computer to show on deletion. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-05-20Cleanup: rename clone_dive() to move_dive()Gravatar Berthold Stoeger
This function clones a dive and clear out the old dive. This corresponds to move semantics. Name the function accordingly. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-05-20Undo: make "delete dive computer" undoableGravatar Berthold Stoeger
Simply reuse the code for "move dive computer" by creating a DiveComputerBase base class. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-05-20Undo: make "move dive computer to front" undoableGravatar Berthold Stoeger
Instead of the elegant solution that just modifies the dive, keep two copies and add either the old or the new copy. This is primitive, but it trivially keeps the dives in the right order. The order might change on renumbering the dive computers. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2019-05-15Convert the atmospheric pressure in the Information Tab to an editable fieldGravatar willemferguson
The Information tab shows the atmospheric pressure. Make this value editable and also ensure that changes to it are undo-able. Signed-off-by: willemferguson <willemferguson@zoology.up.ac.za>
2019-05-12Cleanup: remove UTF8 macrosGravatar Berthold Stoeger
At some places we use UTF8 string literals. Therefore, we effectively only support UTF8 build systems. We might just as well remove all the other UTF_* macros and use direct string literals. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-05-11Dive site: create new dive site at location from GPS dataGravatar Berthold Stoeger
Some dive computers save GPS data. Currently, this is stored by libdivecomputer in an "extra field". When generating a new dive site for a dive try to use this data to place the dive site. To do so, create a "dive_get_gps_location()" function. This function can be extended later to use e.g. event. When creating a dive site, use the result of this function over a potential pre-existing dive site. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-04-15make sure to clear dives on dive split failureGravatar Linus Torvalds
The dive splitting code returns an error code when splitting fails, but it turns out that the C++ UI code doesn't actually look at the error code, and instead expected the resulting dives to be NULL if an error happened and the split didn't succeed for whatever reason. Which is kind of lazy of it, but we might as well clear the resulting dives and make the UI code happy. This should fix the problem that Celia Marlowe reported on the Subsurface google groups forum. Reported-by: Celia Marlowe Acked-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at> Fixes: 145f70aab5 ("Undo: implement split-out of dive computer") Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2019-04-12Undo: update cylinder and weight models on pasteGravatar Berthold Stoeger
When pasting (or undoing paste) the cylinders or weights may change. Send the appropriate signals and update the models accordingly. Currently, this means copying from current dive to displayed dive, but hopefully we can get rid of "displayed_dive" in the not so distant future. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-04-12Core: introduce taglist_copy() functionGravatar Berthold Stoeger
Taglists were only copied in dive.c using the STRUCTURED_LIST_COPY macro. Export that functionality in a function. This will be needed for undo of dive-pasting. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-04-12Dive site: add dive site ref-countingGravatar Berthold Stoeger
Instead of setting dive->dive_site directly, call the add_dive_to_dive_site() and unregister_dive_from_dive_site() functions. In the parser this turned out to be a bit tricky. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-04-12Dive sites: prepare for dive site ref-countingGravatar Berthold Stoeger
Add a dive site table to each dive site to keep track of dives that have been added to a dive site. Add two functions to add dives to / remove dives from dive sites. Since dive sites now contain a dive table, the order of includes had to be changed: "divesite.h" now includes "dive.h" and not vice-versa. This caused some include churn. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-04-12Dive site: set UUID only on save or loadGravatar Berthold Stoeger
Since the UUID will be overwritten on save and is only used on save and load, set it only on save or load. For other created dive sites, leave the UUID field uninitialized. This means that the UUID will change between saves. Let's see how the git saver handles that. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-04-12Dive site: add dive site table parameter to dive site functionsGravatar Berthold Stoeger
To enable undo of dive site functions, it is crucial to work with different dive site tables. Therefore add a dive site table parameter to dive site functions. For now, always pass the global dive site table. Thus, this commit shouldn't alter any functionality. After this change, a simple search for dive_site_table reveals all places where the global dive site table is accessed. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-04-07Merge extra_data list when merging two dives of the same dive computerGravatar Linus Torvalds
When merging two dives into a longer one, merge the dive computer extra_data list too. We just pick all the extra-data (but avoid entirely duplicate key/value entries). Note that this can cause confusing extra-data, in that both dives migth have things like "battery percentage at beginning/end of dive" keys, and if the values are different, you'll now get *both* of those values, but that's better than randomly just taking one of them. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2019-04-04Undo: implement split-out of dive computerGravatar Berthold Stoeger
Allow splitting out a dive computer into a distinct dive. This is realized by generating a base class from SplitDive. This turned out to be more cumbersome than expected: we don't know a-priori which of the split dives will come first. Since the undo-command saves the indices where the dives will be insert, these have to be calculated. This is an premature optimization, which makes more pain than necessary. Let's remove it and simply determine the insertion index when executing the command. Original code by Linus Torvalds <torvalds@linux-foundation.org>.

2019-03-19Misc: replace some FIXME commentsGravatar Dirk Hohndel
All these aren't actually things that need fixing, they are observations about the code. Given that LGTM.com reports FIXME comments as Alerts, let's change the ones that aren't about things that need fixing to something more harmless. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2019-02-28Cleanup: make dive_set_geodata_from_picture() local to dive.cGravatar Berthold Stoeger
The function dive_set_geodata_from_picture() is only used in dive.c. Make it local to that translation unit. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-01-09Import: merge dives trip-wiseGravatar Berthold Stoeger
The old way of merging log-files was not well defined: Trips were recognized as the same if and only if the first dives started at the same instant. Later dives did not matter. Change this to merge dives if they are overlapping. Moreover, on parsing and download generate trips in a separate trip-table. This will be fundamental for undo of dive-import: Firstly, we don't want to mix trips of imported and not-yet imported dives. Secondly, by merging trip-wise, we can autogroup the dives in the import-data to trips and merge these at once. This will simplify the code to decide to which trip dives should be autogrouped.

2018-12-17Core: remove count_dives_with_*() functionsGravatar Berthold Stoeger
The simplified filter-widget doesn't present lists of existing values with counts. Thus, a whole slew of count_dives_with_*() functions can be removed. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-12-14Cleanup: remove split_dive_*() functionsGravatar Berthold Stoeger
In 302f6adb79681da3fe53336f1e4c7525f46fd47d dive-splitting was made undo-able. To this goal, the dive-splitting functions were split in two types: Those that operate directly on the divelist and those that only allocate the dives. The former are not in use anymore, therefore remove them. Since only the latter remain, remove the "_dont_insert" appendix of the name. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-12-13Dive media: add media to closest diveGravatar Berthold Stoeger
Currently, when selecting "Load media files even if time does not match the dive time", the media are added to *all* selected dives. Instead add it to the closest dive. This seems like the less surprising behavior. Of course now if the user really wants to add a media file to multiple dives, they will have to do it manually. To avoid a messy interface, this is solved by moving the iterate- over-selected-dives loop to the core. Thus, a helper-function can be made local to its translation unit. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-11-20Core: replace tripflag by notrip booleanGravatar Berthold Stoeger
The only remaining use of the tripflag was to mark dives that were removed explicitly from a trip, i.e. shouldn't be autogrouped. Therefore replace the enum by a simple boolean. Currently, there is no way of unsetting the notrip flag. But this shouldn't result in a user-visible change. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-11-20Core: remove ASSIGNED_TRIP trip flagGravatar Berthold Stoeger
The distinction between ASSIGNED_TRIP and IN_TRIP was used to prefer non-autogenerated trips on merging of dives. But owing to bit rot this seem to have worked only partially anyway: The IN_TRIP field was set in create_and_hookup_trip_from_dive() and immediately overwritten in add_dive_to_trip() called in the next line. Instead, use the trip->autogen flag to check for priority and remove the ASSIGNED_TRIP flag alltogether. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-30Fix gasmix for OTU calculationGravatar Robert C. Helling
With the fixed sematics of get_gasmix to return the new gasmix for the time of a gas switch (added comments to make this clear), in the OTU calculation we need the previous gasmix for the interval up to the current time. Signed-off-by: Robert C. Helling <helling@atdotde.de>
2018-10-30Fixed get_gas_at_time for equal timesGravatar Robert C. Helling
This fixes a subtle bug introduced in 5c4569247a31c which unified two functions finding the gasmix at a given time during the dive. There was a slight difference, though: Does a gaschange exactly at that time count or not? For the planner to work, the answer has to be in the affirmative. Signed-off-by: Robert C. Helling <helling@atdotde.de>
2018-10-29Dive site: replace dive->dive_site_uuid by dive_siteGravatar Berthold Stoeger
Replace the UUID reference of struct dive by a pointer to dive_site. This commit is rather large in lines, but nevertheless quite simple since most of the UUID->pointer work was done in previous commits. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-29Dive site: return pointer to dive_site in create_dive_site_*()Gravatar Berthold Stoeger
This changes more of the dive-site interface to return pointers instead of UUIDs. Currently, most call sites directly extract UUIDs afterwards. Ultimately, the UUIDs will be generally replaced by pointers, which will then simplify these callers. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-23Core: export free_picture()Gravatar Berthold Stoeger
Export the free_picture() function from dive.c. The parser may need this in case of truncated files to free its temporary resources. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-21Add 'location_t' data structureGravatar Linus Torvalds
Instead of having people treat latitude and longitude as separate things, just add a 'location_t' data structure that contains both. Almost all cases want to always act on them together. This is really just prep-work for adding a few more locations that we track: I want to add a entry/exit location to each dive (independent of the dive site) because of how the Garmin Descent gives us the information (and hopefully, some day, other dive computers too).

2018-10-16Core: use free_dc_contents() in delete_current_divecomputer()Gravatar Berthold Stoeger
delete_current_divecomputer() had some duplicate code to release dive-computer resources. Use the free_dc_contents() function instead. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-16Core: copy / free serial and fw_version items of struct divecomputerGravatar Berthold Stoeger
The serial and fw_version strings of struct divecomputer were copied by pointer. This worked because they were never freed or modified. Instead, do a deep copy of the strings and free them when appropriate. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-16Core: copy and free extra_data of dive computer structureGravatar Berthold Stoeger
On dive computer copy, the extra data (a list of key/value pairs) was simply copied as a pointer. This worked because the list was never freed nor modified. Copy and free the list on dive computer copy and free, respectively. This made it necessary to move the STRUCTURE_LIST_* macros up in the dive.c file.

2018-10-15Core: fix broken commit e5dca8228eGravatar Berthold Stoeger
In commit e5dca8228e6b60cac5957726700c66d0565c064e a fixed order of the arguments to merge_dives() was introduced: first dive old, second dive downloaded. This made the dl variable, which pointed to the downloaded dive useless. One instance was forgotten, which led to a null-dereference. Remove.

2018-10-15Cleanup: remove apparently dead code in sanitize_cylinder_type()Gravatar Berthold Stoeger
sanitize_cylinder_type(), which is indirectly called from fixup_dive(), had ft^3 -> mliter conversion code, which was executed on the condition "xml_parsing_units.volume == CUFT". But nowhere in the code base would xml_parsing_units.volume ever be set to non-metric. Moreover, xml_parsing_units reflects the units of the latest parsed XML file, but fixup_dive() is called in numerous contexts not related to XML parsing. Therefore, the whole piece of code seems highly questionable. Remove this code. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-15Core: copy whole list in copy_dc_renumber()Gravatar Berthold Stoeger
copy_dc_renumber() is an internal function to copy dive computers and renumber the cylinders. Since only the structure was copied, in the case of multi-dc dives, the merged dives shared the same computer. If one of them was freed, use-after-free crashes would happen.

2018-10-15Dive list: make deep copy of picture list on mergeGravatar Berthold Stoeger
On merging make a deep copy of the picture list, to avoid a use-after-free crash after the orginal dive is deleted. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-15Dive list: fix crash on dive importGravatar Berthold Stoeger
In commit 8c2383b4952fa22d41745d29484462ed6a67112b dive merging was changed to not modify the original dive. On import, dives were then merged and the original deleted. The merge_weightsystem_info() was not adapted accordingly (deep copy of string instead of pointer), leading to a use-after-free crash. Resolve this by doing a deep copy.

2018-10-13Dive site: un-globalize displayed_dive_siteGravatar Berthold Stoeger
The global object displayed_dive_site is used a a backing-store by the dive-site-edit widget. All external accesses were removed, therefore make the object local to the widget. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-11Undo: don't modify source-dives on mergeGravatar Berthold Stoeger
For undo, it is crucial that commands don't modify existing dives. Unfortunately, dive merging would write into the data-structures of the to-be-merged dives. To prevent it from doing so, make the input dives const-pointers. This led to a whole cascade of functions that had to take const and significant churn. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-11Undo: implement rudimentary support for undo of dive-mergingGravatar Berthold Stoeger
For this, an output-parameter was added to the backend merge_dives() function. When non-zero, instead of adding the merged dive to the preferred trip, the preferred trip is returned to the caller. Since the new UndoObject, just like the delete-dives UndoObject, needs to remove/readd a set of dives, the corresponding functionality was split-off in a helper function. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-11Undo: implement rudimentary support for undo of dive-splittingGravatar Berthold Stoeger
For this, the core functionality of the split_dive() and split_dive_at_time() functions were split out into new split_dive_dont_insert() and split_dive_at_time_dont_insert(), which do not add the new dives to the log. Thus, the undo-command can take ownership of these dives, without having to remove them first. The split-dive functionality is temporarily made desktop-only until mobile also supports "UndoObjects". Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-06Import: remove dive->downloaded logicGravatar Berthold Stoeger
Dive importing is now performed via a distinct table which is merged into the main dive table. Thus, it is known which of the dive is new and which is old. This information can now be implicitely encoded in the parameter-position of merge_dive() [i.e. pass old as first and new as second dive]. This makes marking of downloaded dives via a flag unnecessary. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-09-29Cleanup: split out free_dive() function from delete_single_dive()Gravatar Berthold Stoeger
Currently, we can only delete dives that are indexed in the main dive table. In the future, we will have to delete dives outside of this table (e.g. for undo). Therefore, split out the free_dive() function from delete_single_dive(), which takes an index into the main dive table. In the process, adopt the dive freeing-code from clear_dive(), which frees more data than the code in delete_single_dive(). This potentially fixes a memory-leak. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-09-19Dive media: on import read metadata only onceGravatar Berthold Stoeger
On import of dive media, the timestamp is read from the metadata to check if the image belongs to the selected dives. The pictures are then listed in a dialog. Currently, the metadata is read twice if images are outside of a dive: once in picture_check_valid() and if it turns out that the picture is not valid again in picture_get_time() to display the proper timestamp. Even though metadata-extraction is reasonably fast, this is a bit of an embarrassment. Instead, read the timestamps only once in the constructor of the dialog and from then on only used these timestamps. Keep the timestamps in a QVector. Rename the picture_check_valid() function to picture_check_valid_time() and pass a timestamp instead of a filename. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
