2020-01-10code cleanup: introduce empty_cylinder constantGravatar Dirk Hohndel
This deals with the issue of initializing structs in C++. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
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.

2019-08-08Core: pass dive, cylinder-id to fill_default_cylinderGravatar Berthold Stoeger
The fill_default_cylinder() function calculated the MOD based on the currently displayed dive. This does not seem to make sense: - When importing dives, why would we care about the altitude and salinity of the currently displayed dive, possibly from a different trip. - The planner is supposed to be thread-safe and should not touch global variables. Of course this means that the importing-functions have to fill out altitude and salinity before creating the default cylinder, but this is their problem. For a freshly created dive they will get the default values, which still seems less random than the values from the displayed dive. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
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>
2019-04-12Dive 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>
2019-04-12Parser: parse into custom dive site tableGravatar Berthold Stoeger
To extend the undo system to dive sites, the importers and downloaders must not parse directly into the global dive site table. Instead, pass a dive_site_table argument to parse into. For now, always pass the global dive_site_table so that this commit should not cause any functional change. 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>
2019-01-09Parser: add trip_table parameter to parsing functionsGravatar Berthold Stoeger
To allow parsing into arbitrary trip_tables, add the corresponding parameter to the parsing functions and the parser state. Currently, all callers pass the global trip_table so there should be no change in functionality. These arguments will be replaced in subsequent commits. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
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>
2018-10-06Core: remove dive->downloaded flagGravatar Berthold Stoeger
This flag had two distinct uses: - signal that dives were downloaded, not imported - use to mark imported dives Both are not used anymore, therefore remove the flag. The uemis downloaded misused the flag to mark deleted dives. Instead misuse the "hidden_by_filter" flag. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-09-28Parser: parse text-based files into arbitrary tableGravatar Berthold Stoeger
In d815e0c9476ef62e6b84fb28ce48ab7cddefe77e a dive_table pointer was added to the parsing functions to allow parsing into tables other than the global dive table. This will be necessary for undo of import and implementation a cleaner interface. A few cases, notably CSV and proprietary formats were forgotten. Implement parsing into arbitrary tables also for these cases. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2017-10-07Safeguards for Liquivision importGravatar Miika Turkia
I have received one sample log where after parsing a bunch of dives properly, the sample count hits zero, and after that it is astronomical. In case of zero, the only data we have is dive date and time of a duplicate dive that we already parsed with proper dive profile. So preventing a crash with this hack without properly understanding the weird file format. Signed-off-by: Miika Turkia <miika.turkia@gmail.com>
2017-07-28Import all pressure sensors from Liquivision logsGravatar Linus Torvalds
The other pressure sensors were disabled on import because we didn't use to handle multiple sensors well at all. Now it "JustWorks(tm)". Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
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.

2017-07-20Unify sample pressure and o2pressure as pressure[2] arrayGravatar Linus Torvalds
We currently carry two pressures around for all the samples and plot info, but the second pressure is reserved for CCR dives as the O2 cylinder pressure. That's kind of annoying when we *could* use it for regular sidemount dives as the secondary pressure. So start prepping for that instead: don't make it "pressure" and "o2pressure", make it just be an array of two pressure values. NOTE! This is purely mindless prepwork. It literally just does a search-and-replace, keeping the exact same semantics, so "pressure[1]" is still just O2 pressure. But at some future date, we can now start using it for a second sensor value for sidemount instead.

2017-06-15Fix buffer overrun and primary sensor id issues in Liquivision importGravatar Robert Bodily
This changeset fixes 5 issues specific to importing from Liquivision dive logs: Issue #1: Buffer overrun causes segmentation fault. At the end of a dive record, untranslatable data is skipped and the file is scanned for the start of the next dive. This scan was implemented without regard to buffer size and so the scan ran over the buffer boundary when trying to scan for the next record after importing the last record in the file. Issue #2: Incorrect identification of the primary sensor. The primary tank pressure transmitter was being identified by using the sensor ID reported in the first pressure event record encountered. When diving with multiple transmitters (buddy, student, or group transmitters), this is often not the case and results in the buddy or other group transmitter's pressure data being imported instead of the primary's. Through empirical observation of several multi-sensor logs, I identified a previously unhandled event code (0x10) as marking a sensor identification event record. Parsing this record allows the primary and other sensors to be definitively identified regardless of which one sends the first pressure event. Issue #3: Sensor values added to the sample collection regardless of sensor ID. When processing events, the code previously dropped through to create a sample for every pressure event record, regardless of which sensor ID that event is associated with. Pressure events for sensors other than the primary are now ignored and omitted from the sample collection. Issue #4: Duplicate samples when pressure event time syncs with sample time. The sample index (d) was not incremented in this specific case resulting in a duplicate sample (for the same sample time) being created when processing the next pressure event record. Issue #5: Unsigned time difference results in erroneous interpolated samples. When interpolating/extrapolating depth and temperature values for a between- samples pressure event, a signed time value is subtracted from an unsigned time value, resulting in an unsigned term. This term is used as a scaling factor and should be signed to allow for a negative value. Currently, negative values are instead treated as large unsigned values which result in erroneous scaled depth and temperature values.

2017-03-09Fix potential double/float to int rounding errorsGravatar Jeremie Guichard
Not using lrint(f) when converting double/float to int creates rounding errors. This error was detected by TestParse::testParseDM4 failure on Windows.

2016-04-04Move subsurface-core to core and qt-mobile to mobile-widgetsGravatar Dirk Hohndel
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. And while cleaning up the resulting change in the path name for include files, I decided to clean up those even more to make them consistent overall. This could have been handled in more commits, but since this requires a make clean before the build, it seemed more sensible to do it all in one. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
