Provide for a dive_computer_type variable within dc structure This patch lays the foundation for differentiating between open-circuit(OC)dives and rebreather dives (CCR). The following were done: 1) In dive.h add an enum type dive_computer_type 2) In dive.h add two more fields to the dc structure: a) dctype (an enum field indicating dc type) b) no_o2sensor (indicating number of o2 sensors for this dc) 3) In parse-xml.c add a function trimspace that strips any whitespace from a string. This is used by two functions: utf8_string as well as by get_dc_type, described below. The pointer to buffer is not changed in order to ensure consistency when the buffer is freed. 4) In parse-xml.c add a function get_dc_type. This parses the dc_type string from xml and assigns an enum value which will later be returned to the function that parses the dc variables.

Core: remove MAX_CYLINDERS restriction 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.

Do more dive fixup for each dive computer In commit b6c9301e5847 ("Move more dive computer filled data to the divecomputer structure") we moved the fields that get filled in by the dive computers to be per-divecomputer data structures. This patch re-creates some of those fields back in the "struct dive", but now the fields are initialized to be a reasonable average from the dive computer data. We already did some of this for the temperature min/max fields for the statistics, so this just continues that trend. The goal is to make it easy to look at "dive values" without having to iterate over dive computers every time you do. Just do it once in "fixup_dive()" instead.

/* Calculated based on dive computer data */
Finish removing accesses to first divecomputer instead of dive This adds watertemp and airtemp to the dive, populates them in fixup and uses them elsewhere in the code. WARNING: as a sideeffect we now edit the airtemp in the dive, but we never display this in the DIve Info notebook (as that always displays the data from the specific selected divecomputer). This is likely to cause confusion. It's consistent behavior, but... odd. This brings back the desire to have a view of "best data available" for a dive, in addition to the "per divecomputer" view. This would also allow us to consolidate the different pressure graphs we may be getting from different divecomputers (consider the case where you dive with multiple air integrated computers that are connected to different tanks - now we could have one profile with all the correct tank pressure plots overlayed - and the best available (or edited) data in the corresponding Dive Info notebook. This commit also fixes a few remaining accesses to the first divecomputer that fell through the cracks earlier and does a couple of other related cleanups.

Move duration to dive structure and replace accessor function When starting on this quest to stop using the first divecomputer instead of data for the whole dive in commit eb73b5a528c8 ("Duration of a dive is the maximum duration from all divecomputers") I introduced an accessor function that calculates the dive duration on the fly as the maximum of the durations in the divecomputers. Since then Linus and I have added quite a few of the variables back to the dive data structure and it makes perfect sense to do the same thing for the duration as well and simply do the calculation once during fixup. This commit also replaces accesses to the first divecomputer in likely_same_dive to use the maxdepth and meandepth of the dive (those two slipped through the cracks in the previous commits, it seems).

filter: add fulltext filtering code Add code that indexes all words of a dive and provides searching for words. A query is represented by the FullTextQuery class, which can be initialized by assigning a string to it. It is basically a list of words. The result of a search is stored in the FullTextResult class, which is a list of dives. The actual indexing and searching is implemented in the FullText class. However, this class is not exported because the interface is partially accessible to C. Notably, the reloading of the fulltext index is done from the C core. Currently, the indexing and searching is totally unoptimized. In a ~4000 dives test-log searches typically took single-digit ms times. There is ample room for optimization (e.g. when searching for multiple words, chose the words with few dives first and when down to a few dives, check them individually). The words of each dive are tokenized and uppercased and cached with the dive. A pointer to these words is stashed in the dive structure. For now, compile only on desktop.

extern void cylinder_renumber(struct dive *dive, int mapping[]);
Core: remove MAX_CYLINDERS restriction 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.

extern int same_gasmix_cylinder(const cylinder_t *cyl, int cylid, const struct dive *dive, bool check_unused);
Calculate nitrogen and helium gas pressures for CCR after import from CSV Currently the gas pressures stored in structures of pressure are calculated using the gasmix composition of the currently selected cylinder. But with CCR dives the default cylinder is the oxygen cylinder (here, index 0). However, the gas pressures need to be calculated using gasmix data from cylinder 1 (the diluent cylinder). This patch allows setting the appropriate cylinder for calculating the values in the structures of pressure. It also allows for correctly calculating gas pressures for any open circuit cylinders (e.g. bailout) that a CCR diver may use. This is performed as follows: 1) In dive.h create an enum variable {oxygen, diluent, bailout} 2) Within the definition of cylinder_t, add a member: cylinder_use_type This stores an enum variable, one of the above. 3) In file.c where the Poseidon CSV data are read in, assign the appropriate enum values to each of the cylinders. 4) Within the definition of structure dive, add two members: int oxygen_cylinder_index int diluent_cylinder_index This will keep the indices of the two main CCR cylinders. 5) In dive.c create a function get_cylinder_use(). This scans the cylinders for that dive, looking for a cylinder that has a particular cylinder_use_type and returns that cylinder index. 6) In dive.c create a function fixup_cylinder_use() that stores the indices of the oxygen and diluent cylinders in the variables dive->oxygen_cylinder_index and dive->diluent_cylinder_index, making use of the function in 4) above. 7) In profile.c, modify function calculate_gas_information_new() to use the above functions for CCR dives to find the oxygen and diluent cylinders and to calculate partail gas pressures based on the diluent cylinder gas mix. This results in the correct calculation of gas partial pressures in the case of CCR dives, displaying the correct partial pressure graphs in the dive profile widget.

Be much more careful about merging dives This patch changes the dive merging to be much more careful about things, because it turns out that we had several small oddities that caused big merge issues. The oddities are: - the dive "duration" is actually how long we spend under water. But that means that when we do "dive->when + dive.duration.seconds" to calculate the end of the dive, that is nonsensical if you came up to the surface in the middle of a dive. Now, normally you don't see profiles like that, but once you start merging dives together, it can go from "small detail" to "dominant factor". - We have two different cases of merging: the automatic "merge new dive computer download if it looks like the same dive" (which always has a merge offset of 0, since we merge it as a new dive computer) and the "merge two different dives into one longer dive. The code assumed that it could look at the "downloaded" flag for the dive to check one or the other, but that doesn't really work. Reading a dive from an XML file isn't any different from downloading it. So we need to change the logic to determine what kind of merge it is to actually check the passed-in time offset. With this, Stuart Vernon's test-case of eight dives with short surface intervals in between end up merging correctly into one dive.

Make 'get_dive_by_diveid()' work even for non-primary dive computers It's only used by the Uemis importer, and Dirk always seems to import his Uemis data first, so it wasn't very noticeable. But if the Uemis data wasn't the first dive computer, it would not find the dive. Side note: just comparing deviceid is not correct. We should pass in the device model too. But again, that will realistically never really matter, since non-Uemis importers will generate complex SHA1 hashes of the dive data for the dive ID, so a collision with the Uemis numbers is very unlikely.

Stop using the "git descriptor file" model Instead, just encode the git repository information in the filename. We want to make it much harder to make it match a real filename, but to still allow easy browsing with the file manager interface. So the git repository "filename" format is the path to the git repository directory, with the branch name encoded as "[branch]" at the end rather than the "path:branch" format that we used in the descriptor file. [ For example, on Windows, a filename like "c:\my.xml" could be interpreted as the branchame "\my.xml" in the repository in the directory "c" ] In particular, with this model, no filename that ends with ".xml" could possibly ever be considered a git repository name, since the last character of a git pathname is always ']'.

win32: optimize the console and logging logic Currently one has to explicitly use --win32console and/or --win32log to enable a dedicated console (a console window that opens next to the Subsurface window) or to enable file logging on Win32. This patch makes the following changes: - removes the --win32* command line arguments - removes the dedicated console window support - if the app starts from a shortcut and not from a console, always redirect stderr and stdout to _err & _out log files - if the app starts from a console redirect stderr and stdout to that console Signed-off-by: Lubomir I.

With windows.c's subsurface_console_init() we are able to either redirect stdout and stderr to the terminal from which subsurface.exe was started (always happens; --win32console does nothing in this case) or if --win32console is explicitly added to a shortcut, create a dedicated console window and monitor the output there. if set, WIN32_CONSOLE_APP is a condition that will make the subsurface_console_init() and subsurface_console_exit() functions NOP on Windows.

Cleanup: simplify dive_getUniqID() 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.

Core: remove MAX_CYLINDERS restriction 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.

First step in cleaning up cylinder pressure sensor logic This clarifies/changes the meaning of our "cylinderindex" entry in our samples. It has been rather confused, because different dive computers have done things differently, and the naming really hasn't helped. There are two totally different - and independent - cylinder "indexes": - the pressure sensor index, which indicates which cylinder the sensor data is from. - the "active cylinder" index, which indicates which cylinder we actually breathe from. These two values really are totally independent, and have nothing what-so-ever to do with each other. The sensor index may well be fixed: many dive computers only support a single pressure sensor (whether wireless or wired), and the sensor index is thus always zero. Other dive computers may support multiple pressure sensors, and the gas switch event may - or may not - indicate that the sensor changed too. A dive computer might give the sensor data for *all* cylinders it can read, regardless of which one is the one we're actively breathing. In fact, some dive computers might give sensor data for not just *your* cylinder, but your buddies. This patch renames "cylinderindex" in the samples as "sensor", making it quite clear that it's about which sensor index the pressure data in the sample is about. The way we figure out which is the currently active gas is with an explicit has change event. If a computer (like the Uemis Zurich) joins the two concepts together, then a sensor change should also create a gas switch event. This patch also changes the Uemis importer to do that. Finally, it should be noted that the plot info works totally separately from the sample data, and is about what we actually *display*, not about the sample pressures etc. In the plot info, the "cylinderindex" does in fact mean the currently active cylinder, and while it is initially set to match the sensor information from the samples, we then walk the gas change events and fix it up - and if the active cylinder differs from the sensor cylinder, we clear the sensor data.

Don't write back dive data that hasn't changed in git This caches the git ID for the dive on load, and avoids building the dive directory and hashing it on save as long as nothing has invalidated the git ID cache. That should make it much faster to write back data to the git repository, since the dive tree structure and the divecomputer blobs in particular are the bulk of it (due to all the sample data). It's not actually the git operations that are all that expensive, it's literally generating the big blob with all the snprintf() calls for the data.

Cleanup: unify get_gas_at_time() and get_gasmix() 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>

/* Get gasmixes at increasing timestamps.
Cleanup: return gasmix by value 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>

* In "evp", pass a pointer to a "struct event *" which is NULL-initialized on first invocation.
* On subsequent calls, pass the same "evp" and the "gasmix" from previous calls.

Cleanup: const-ify functions taking pointers to events 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>

Add "get_gasmix()" helper function to iterate over gas changes We have a few places that used to get the gasmix by looking at the sensor index in the plot data, which really doesn't work any more. To make it easier for those users to convert to the new world order, this adds a "get_gasmix()" function. The gasmix function takes as its argument the dive, the dive computer, and the time. In addition, for good performance (to avoid looping over the event list over and over and over again) it maintains a pointer to the next gas switch event, and the previous gas. Those need to be initialized to NULL by the caller, so the standard use-case pattern basically looks like this: struct gasmix *gasmix = NULL; struct event *ev = NULL; loop over samples or plot events in increasing time order: { ... gasmix = get_gasmix(dive, dc, time, &ev, gasmix); ... } and then you can see what the currently breathing gas is at that time. If for some reason you need to walk backwards in time, you can just pass in a NULL gasmix again, which will reset the event iterator (at the cost of now having to walk all the events again).

Dive sites: prepare for dive site ref-counting 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.
