2013-02-03Fixing SP handling in planner, adding eventGravatar Jan Schubert
This moves some double/floating handling for po2 to plain integer. There are still non int values around (also for phe and po2) in the plot area. Signed-off-by: Jan Schubert <Jan.Schubert@GMX.li> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-02-02Add 'Save As' entry to context menu shown when right clicking on a diveGravatar Pierre-Yves Chibon
Something which is nice especially when asked on the list to share an interesting dive is the possibility to save just some dives into a file. This commit adds to the context menu shown with right-click the 'Save As' entry. This entry allows to save selected dives.

2013-01-31Better algorithm to merge gps locations & locations names from webserviceGravatar Dirk Hohndel
This no longer abuses the dive merging code (which would leave stray "dives" behind if a gps fix couldn't be merged with any of the dives) and instead parses the gps fixes into a second table and then walks that table and tries to find matching dives. The code tries to be reasonably smart about this. If we have auto-generated GPS fixes at regular intervals, we look for a fix that is during a dive (that's likely when the boat where the phone is staying dry is more or less above the diver having fun). And if we have named entries (so the user typed in a location name) we try to match them in order to the dives that happened "that day" (where "that day" is about 6h before and after the timestamp of the gps fix). This commit also renames dive_has_location() to dive_has_gps_location() as the difference between if(!dive->location) and if(dives_has_location) is a bit too subtle...

2013-01-31Allow using two different tables to hold dives and gps locationsGravatar Dirk Hohndel
This only changes the infrastructure and actually loses functionality as it no longer does the simplistic "just treat the locations as dives and merge them". The new code that does something "smart" with the gps_location_table is yet to be written. But now we can use the XML parser to put the gps locations downloaded from the webservice into their own data structure. In the process I noticed that we never used the two delete functions in parse-xml.c and removed them. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-01-30Make 'get_dive_by_diveid()' work even for non-primary dive computersGravatar Linus Torvalds
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.

2013-01-30Massive cleanupGravatar Dirk Hohndel
Mostly coding style and whitespace changes plus making lots of functions static that have no need to be extern. This also helped find a bit of code that is actually no longer used. This should have absolutely no functional impact - all changes should be purely cosmetic. But it removes a bunch of lines of code and makes the rest easier to read.

2013-01-28Pick GPS coordinates of dive location via map widgetGravatar Dirk Hohndel
I have some concerns about the way this is implemented - especially the use of gtk_grab_add to make the map widget work has me worried. But it seems to work and survived some test cases that I threw at it. The GtkButton with the Pixmap looks a little off on my screen, but this way it was easy to implement.

2013-01-27UTF8 aware parser for some more GPS formatsGravatar Dirk Hohndel
I'm sure there are better ways to do this, but this appears to grok most rational formats I was able to find. NSEW or positive/negative numbers. Decimal degrees (WGS84) or degrees and decimal minutes (that's what most GPSs seem to provide). I'm sure there are still corner cases that confuse it, but it seemed reasonably robust in testing. I don't really love the ';' as separator but that solves the obvious problem with locales that use a decimal comma. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2013-01-24Remove saving of dive computer nicnames in system configGravatar Linus Torvalds
We save the (more complete) dive computer information in the XML file with serial numbers and firmware version if we know about them, so using a complicated string in the system config was redundant and confusing. So remove that code. NOTE! Since the dive computer nicknames are now only saved if the XML file is saved, we also mark the dive list "changed" when we edit the nicknames. That way we'll be prompted to save things before exiting, even if we don't actually edit any actual dive data.

2013-01-24Save all dive computer nicknames - whether used or notGravatar Linus Torvalds
We used to save dive computer information only if that dive computer was actually used in any of the dives we saved. But we can simplify the code if we just always save any dive computers we know about. And it does allow for some usage cases where you have nicknames for other peoples computers that you may not actively use, but you want to see if you end up loading multiple XML files in one go. So there's just no compelling reason to not just save all the info we have. And this will make it less painful to remove the "use system config for dive computer nicknames", because you can also use this to continue to gather dive computer info in a separate XML file if you want to.

2013-01-23Fix temperature rounding issuesGravatar Linus Torvalds
Temperatures can actually be negative, which means that rounding by adding 0.5 and casting to 'int' is not correct. We could use '(int)(rint(val))' instead, but the only place we care about might as well just print out the floating point representation with a precision of two digits instead. So if you have a dive computer that gives you the precision, you might see '3.5˚C' as the temperature. Remove the helper functions that nobody uses and that get the rounding wrong anyway.

2013-01-23Move more dive computer filled data to the divecomputer structureGravatar Linus Torvalds
This moves the fields 'duration', 'surfacetime', 'maxdepth', 'meandepth', 'airtemp', 'watertemp', 'salinity' and 'surface_pressure' to the per-divecomputer data structure. They are filled in by the dive computer, and normally not edited. NOTE! All actual *use* of this data was then changed from dive->field to dive->dc.field programmatically with a shell-script and sed, and the result then edited for details. So while the XML save and restore code has been updated, all the displaying etc will currently always just show the first dive computer entry.

2013-01-16Only offer to show dive on map if we have location informationGravatar Linus Torvalds
This adds the "Show in map" menu entry to the divelist only if we actually have a location to show. Of course, having some way to visually see whether we have a GPS location even before we show the menu would probably be good. Maybe a marker in the "location" string or something.

This just provides the infrastructure to enter the data, nothing is calculated, yet. This adds a new get_thousandths() helper function so we can enter information of the 'mili-' type as decimal values. So things like "14.5 l/min" or "0.75 cuft/min" are parsed correctly and converted into a ml value.

Opening URI addresses from Subsurface does not work on Windows using the latest GTK bundle from the Gnome website. The reason lies in GIO and GLib and how it obtains assigned applications for protocols and MIME types.

This patch centralizes the definition for surface pressure, oxygen in air, (re)defines all such values as plain integers and adapts calculations. It eliminates 11 (!) occurrences of definitions for surface pressure and also a few for oxygen in air. It also rewrites the calculation for EAD, END and EADD using the new definitons, harmonizing it for OC and CC and fixes a bug for EADD OC calculation.

O2 narcotic - END: Equivalent Nitrogen (Narcotic) Depth considering just N2 narcotic (ignoring O2) - EADD: Equivalent Air Density Depth Please note that some people and even diving organisations have opposite definitions for EAD and END. Considering A stands for Air, lets choose the above. And considering N for Nitrogen it also fits in this scheme. This patch moves N2_IN_AIR from deco.c to dive.h as this is already used in several places and might be useful for future use also. It also respecifies N2_IN_AIR to a more correct value of 78,084%, the former one also included all other gases than oxygen appearing in air. If someone needs to use the former value it would be more correct to use 1-O2_IN_AIR instead. Signed-off-by: Jan Schubert / Jan.Schubert@GMX.li Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

We used to have this confusing thing where we had two different units (input vs output) that *look* like they are mirror images, but in fact "output_units" was the user units, and "input_units" are the XML parsing units. So this renames them to be clearer. "output_units" is now just "units" (it's the units a user would ever see), and "input_units" is now "xml_parsing_units" and set by the XML file parsers to reflect the units of the parsed file.

We can slowly start moving away from them, we don't want to start exporting that thing as some kind of generic interface. This isn't a pure code movement - because we leave the legacy interfaces alone, there are a few new interfaces in device.c (like "create a new device_info entry") that were embedded into the legacy "create nickname" code, and needed to be abstracted out.

2013-01-09Clean up duplicated depth interpolationGravatar Linus Torvalds
We have several places where we interpolate the depth based on two samples and the time between them. Some of them use floating point, some of them don't, some of them meant to do it but didn't. Just use a common helper function for it. I seriously doubt the floating point here really matters, since doing it in integers is not going to overflow unless we're interpolating between two samples that are hours apart at hundreds of meters of depth, but hey, it gives that rounding to the nearest millimeter. Which I'm sure matters. Anyway, we can probably just get rid of the rounding and the floating point math, but it won't really hurt either, so at least do it consistently. The interpolation could be for other things than just depth, but we probably don't have anything else we'd want to interpolate. But make the function naming generic just in case.

2013-01-08Rewrite of the deco codeGravatar Robert C. Helling
o) Instead of using gradient factors as means of comparison, I now use pressure (as in: maximal ambient pressure). o) tissue_tolerance_calc() now computes the maximal ambient pressure now respecting gradient factors. For this, it needs to know about the surface pressure (as refernce for GF_high), thus gets *dive as an argument. It is called from add_segment() which this also needs *dive as an additional argument. o) This implies deco_allowed_depth is now mainly a ambient-pressure to depth conversion with decorations to avoid negative depth (i.e. no deco obliation), implementation of quantization (!smooth => multiples of 3m) and explicit setting of last deco depth (e.g. 6m for O2 deco). o) gf_low_pressure_this_dive (slight change of name), the max depth in pressure units is updated in add_segment. I set the minimal value in buehlmann_config to the equivalent of 20m as otherwise good values of GF_low add a lot of deco to shallow dives which do not need deep stops in the first place. o) The bogus loop is gone as well as actual_gradient_limit() and gradient_factor_calculation() and large parts of deco_allowed_depth() although I did not delete the code but put it in comments. o) The meat is in the formula in lines 147-154 of deco.c. Here is the rationale: Without gradient factors, the M-value (i.e the maximal tissue pressure) at a given depth is given by ambient_pressure / buehlmann_b + a. According to "Clearing Up The Confusion About "Deep Stops" by Erik C. Baker (as found via google) the effect of the gradient factors is no replace this by a reduced affine relation (i.e. another line) such that at the surface the difference between M-value and ambient pressure is reduced by a factor GF_high and at the maximal depth by a factor GF_low. That is, we are looking for parameters alpha and beta such that alpha surface + beta = surface + gf_high * (surface/b + a - surface) and alpha max_p + beta = max_p + gf_low * (max_p/b + a - max_p) This can be solved for alpha and beta and then inverted to obtain the max ambient pressure given tissue loadings. The result is the above mentioned formula. Signed-off-by: Robert C. Helling <helling@atdotde.de> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2013-01-06Display dive profile of the dive we plan, as we plan itGravatar Dirk Hohndel
As the user enters data into the entry fields, that data is validated and as soon as there is enough data we start constructing a dive profile, including the final ascent to the surface, including required deco stops, etc. This commit still has some serious issues. - when data is input that doesn't validate, we just print a warning to stdout - instead we need to change the backgroundcolor of the input field or something. - when we switch to the last dive in order to show the profile we don't actually search for the last dive - we just show the first one in the tree. This works for the default sort order but is of course wrong otherwise I'm sure there are many other bugs, but I want to push it out where it is right now for others to be able to take a look.

2013-01-04First stab at simplistic dive planningGravatar Dirk Hohndel
This comes with absolutely no gui - so the plan literally needs to be compiled into Subsurface. Not exactly a feature, but this allowed me to focus on the planning part instead of spending time on tedious UI work. A new menu "Planner" with entry "Test Planner" calls into the hard-coded function in planner.c. There a simple dive plan can be constructed with calls to plan_add_segment(&diveplan, duration, depth at the end, fO2, pO2) Calling plan(&diveplan) does the deco calculations and creates deco stops that keep us below the ceiling (with the GFlow/high values currently configured). The stop levels used are defined at the top of planner.c in the stoplevels array - there is no need to do the traditional multiples of 3m or anything like that. The dive including the ascents and deco stops all the way to the surface is completed and then added as simulated dive to the end of the divelist (I guess we could automatically select it later) and can be viewed. This is crude but shows the direction we can go with this. Envision a nice UI that allows you to simply enter the segments and pick the desired stops. What is missing is the ability to give the algorithm additional gases that it can use during the deco phase - right now it simply keeps using the last gas used in the diveplan. All that said, there are clear bugs here - and sadly they seem to be in the deco calculations, as with the example given the ceiling that is calculated makes no sense. When displayed in smooth mode it has very strange jumps up and down that I wouldn't expect. For example with GF 35/75 (the default) the deco ceiling when looking at the simulated dive jumps from 16m back up to 13m around 14:10 into the dive. That seems very odd.

2013-01-04Fix deco calculations to correctly use GF values and add CC supportGravatar Dirk Hohndel
The old implementation was broken in several ways. For one thing the GF values are percentages, so they should normally be 0 < GF < 1 (well, some crazy people like to go above that). With this most of the Bühlmann config constants were wrong. Furthermore, after we adjust the pressure tolerance based on the gradient factors, we need to convert this back into a depth (instead of passing back the unmodified depth - oops). Finally, this commit adds closed circuit support to the deco calculations. Major progress and much more useful at this stage. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-01-03Make GF values configurableGravatar Dirk Hohndel
There are a couple of issues with this commit: GtkEntry should emit the 'changed' signal when it is modified (so that changes in the preferences get applied right away) - but that doesn't appear to be working consistently. Also, this doesn't appear to affect the deco of any dives that I try it with. So my guess is something is wrong with the underlying deco algorithm. That's diappointing.

2013-01-03Consider previous dives when calculating decoGravatar Dirk Hohndel
This also initializes the N2 tissue saturations to correct numbers (setting them to zero was clearly silly). With this commit we walk back in the dive_table until we find a surface intervall that's longer than 48h. Or a dive that comes after the last one we looked at; that would indicate that this is a divelist that contains dives from multiple divers or dives that for other reasons are not ordered. In a sane environment one would assume that the dives that need to be taken into account when doing deco calculations are organized as one trip in the XML file and so this logic should work. One major downside of the current implementation is that we recalculate everything whenever the plot_info is recreated - which happens quite frequently, for example when resizing the window or even when we go into loup mode. While this isn't all that compute intensive, this is an utter waste and we should at least cache the saturation inherited from previous dives (and clear that number when the selected dive changes). We don't want to cache all of it as the recreation of the plot_info may be triggered by the user changing equipment (and most importantly, gasmix) information. In that case the deco data for this dive does indeed have to be recreated. But without changing the current dive the saturation after the last surface intervall should stay the same.

2013-01-01Remove autogroup from the preferences and store per file insteadGravatar Dirk Hohndel
Having two spots to toggle autogroup had always been a clear sign of insanity. The inconsistent ludicrous semantic of when we remembered the state of autogroup was even worse. This finally gets rid of that disaster and drops the autogroup setting from the preferences and makes it instead a per file property. When you save a file, it saves the state of the autogroup toggle. This seems much more useful - you may have files where you want to create trips by default. And others, where you don't. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-12-30First step in cleaning up cylinder pressure sensor logicGravatar Linus Torvalds
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.

Put another way, the old model had fairly inflexible rules: - the dive array is sorted by time - a dive trip is always a contiguous slice of this sorted array which makes perfect sense when you think of the dive and trip list as a physical activity by one person, but leads to various very subtle issues in the general case when there are no guarantees that the user then uses subsurface that way. In particular, if you load the XML files of two divers that have overlapping dive trips, the end result is incredibly messy, and does not conform to the above model at all. There's two ways to enforce such conformance: - disallow that kind of behavior entirely. This is actually hard. Our XML files aren't date-based, they are based on XML nesting rules, and even a single XML file can have nesting that violates the date ordering. With multiple XML files, it's trivial to do in practice, and while we could just fail at loading, the failure would have to be a hard failure that leaves the user no way to use the data at all. - try to "fix it up" by sorting, splitting, and combining dive trips automatically. Dirk had a patch to do this, but it really does destroy the actual dive data: if you load both mine and Dirk's dive trips, you ended up with a result that followed the above two technical rules, but that didn't actually make any *sense*. So this patch doesn't try to enforce the rules, and instead just changes them to be more generic: - the dive array is still sorted by dive time - a dive trip is just an arbitrary collection of dives. The relaxed rules means that mixing dives and dive trips for two people is trivial, and we can easily handle any XML file. The dive trip is defined by the XML nesting level, and is totally independent of any date-based sorting. It does require a few things: - when we save our dive data, we have to do it hierarchically by dive trip, not just by walking the dive array linearly. - similarly, when we create the dive tree model, we can't just blindly walk the array of dives one by one, we have to look up the correct trip (parent) - when we try to merge two dives that are adjacent (by date sorting), we can't do it if they are in different trips. but apart from that, nothing else really changes. NOTE! Despite the new relaxed model, creating totally disjoing dive trips is not all that easy (nor is there any *reason* for it to be easty). Our GUI interfaces still are "add dive to trip above" etc, and the automatic adding of dives to dive trips is obviously still based on date. So this does not really change the expected normal usage, the relaxed data structure rules just mean that we don't need to worry about the odd cases as much, because we can just let them be.

2012-12-30Update deco handlingGravatar Dirk Hohndel
This commit makes deco handling in Subsurface more compatible with the way libdivecomputer creates the data. Previously we assumed that having a stopdepth or stoptime and no ndl meant that we were in deco. But libdivecomputer supports many dive computers that provide the deco state of the diver but with no information about the next stop or the time needed there. In order to be able to model this in Subsurface this adds an in_deco flag to the samples. This is only stored to the XML file when it changes so it doesn't add much overhead but will allow us to display some deco information on dive computers like the Atomic Aquatics Cobalt or many of the Suuntos (among others). The commit also removes the old event based deco code that was commented out already. And fixes the code so that the deco / ndl information is stored for the very last sample as well.

2012-12-28Make add_dc_to_string() skip redundant entriesGravatar Linus Torvalds
There is no point writing out divecomputer nicknames that do not exist (or that match the dive computer model), so don't. Also, make the function to do this static to save-xml.c, which is the only user (I initially didn't _find_ the function to create the XML string because it was illogically hidden in gtk-gui.c), and change the calling convention to be more direct (pass in a string and return a result, rather than modify a "pointer to string").

2012-12-26Add settings section to XML file format and store dive computer IDsGravatar Dirk Hohndel
We only store the model/deviceid/nickname for those dive computers that are mentioned in the XML file. This should make the XML files nicely selfcontained. This also changes the code to consistently use model & deviceid to identify a dive computer. The deviceid is NOT guaranteed to be collision free between different libdivecomputer backends...

2012-12-22Imrpove the nickname handlingGravatar Dirk Hohndel
We now store the model information together with the deviceid and nickname in order to be able to check if we have a record for any dive computer with the same model (as that now triggers our nickname dialog). This changes the format of the config entries for nicknames - the best solution might be to just delete those and start again. What is still missing is the code to store the nicknames in the XML file. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-12-21Remove nickname from divecomputer data structureGravatar Dirk Hohndel
Having it there with the model information seemed to make sense but on second thought it's the wrong spot to keep that information, especially since we were storing it in the XML file in every single dive. This change removes the nickname member from the divecomputer and makes the rest of the code reasonably self consistent. It does not add much of the new code for the new design to handle nicknames.
