2014-02-12Use "rint()" instead of rounding manually with "+ 0.5"Gravatar Linus Torvalds
rint() is "round to nearest integer", and does a better job than +0.5 (followed by the implicit truncation inherent in integer casting). We already used 'rint()' for values that could be negative (where +0.5 is actively wrong), let's just make it consistent. Of course, as is usual for the messy C math functions, it depends on the current rounding mode. But the default round-to-nearest is what we want and use, and the functions that explicitly always round to nearest aren't standard enough to worry about.

2014-02-12Fix default value for missing surface pressure from divecomputerGravatar Linus Torvalds
We should *not* default to the incorrect "1 bar". Instead, we should leave the resuling pressure at 0 mbar, which leaves visual entries empty and uses the default surface pressure for calculations.

Earlier we converted the C++ code to using true/false, and this converts the C code to using the same style. We already depended on stdbool.h in subsurfacestartup.[ch], and we build with -std=gnu99 so nobody could build subsurface without a c99 compiler.

This is super-simplistic and also is kinda wrong. It forces all tanks that haven't been specified by the DC (so far only Atomics Aquatics Cobalt and UEMIS Zurich (which doesn't even use libdivecomputer) to be AL80.

This may seem like a really odd change - but with this change the Qt tools can correctly parse the C files (and qt-gui.cpp) and get the context for the translatable strings right. It's not super-pretty (I'll admit that _("string literal") is much easier on the eye than translate("gettextFromC", "string literal") ) but I think this will be the price of success.

2013-10-03Importing salinity and atmospheric pressure from DC.Gravatar Patrick Valsecchi
One cannot expect #ifdef to work with enum values. So the code for getting the salinity was basically never compiled in.

2013-06-18Converting the device_info list into a Qt data structureGravatar Dirk Hohndel
This data structure was quite fragile and made 'undo' when editing rather hard to implement. So instead I decided to turn this into a QMultiMap which seemed like the ideal data structure for it. This map holds all the dive computer related data indexed by the model. As QMultiMap it allows multiple entries per key (model string) and disambiguates between them with the deviceId. This commit turned out much larger than I wanted. But I didn't manage to find a clean way to break it up and make the pieces make sense. So this brings back the Ok / Cancel button for the dive computer edit dialog. And it makes those two buttons actually do the right thing (which is what started this whole process). For this to work we simply copy the map to a working copy and do all edits on that one - and then copy that over the 'real' map when we accept the changes.

2013-03-03Try to capture some more potential buffer overflows caused by localizationGravatar Dirk Hohndel
A couple of these could clearly cause a crash just like the one fixed by commit 00865f5a1e1a ("equipment.c: Fix potential buffer overflow in size_data_funct()"). One would append user input to fixed length buffer without checking. We were hardcoding the (correct) max path length in macos.c - replaced by the actual OS constant. But the vast majority are just extremely generous guesses how long localized strings could possibly be. Yes, this commit is likely leaning towards overkill. But we have now been bitten by buffer overflow crashes twice that were caused by localization, so I tried to go through all of the code and identify every possible buffer that could be affected by this.

2013-02-07Don't re-use the dive computer model string for all downloaded divesGravatar Linus Torvalds
When we download dives with libdivecomputer, we create this strdup'ed name of the model information, but we then re-use that (single) strdup allocation for every dive we download. This works fine *until* you start freeing those dives (possibly directly after the download because they are redundant), at which point things go to hell in a handbasket, since there is just the one allocation for all the different dives. Fix by just doing another strdup() at the point where we assign the model information to the dive computer.

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.

2013-01-22libdivecomputer: add air temperature fixups for SuuntoGravatar Linus Torvalds
libdivecomputer doesn't actually seem to support air temperature reporting at all, but at least for Suunto dive computers the air temperature is recorded as the temperature for the first sample. So since we already have vendor-specific libdivecomputer hacks, let's just add that one as a rule. It may be that other divecomputers do this too, so this adds it as a generic concept - it's just that right now the flag for "air temperature in first sample" is only set for Suunto dive computers.

2013-01-22Fix suunto serial number confusion in libdivecomputerGravatar Linus Torvalds
libdivecomputer has started giving the Suunto serial numbers in a different format, which means that we have the same device with two different serial numbers, and then we need two different ways of turning the numerical entity into a string. Look at the number pattern to see figure out which version of the format it is that libdivecomputer is reporting, and turn it back into the original format so that we can reliably give the right string for it. This also mean sthat the device ID stays the same regardless of libdivecomputer version. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2013-01-09Assemble the actual Suunto serial numberGravatar Linus Torvalds
It turns out that the serial number returned by libdivecomputer isn't really the serial number as interpreted by the vendor. Those tend to be strings, but libdivecomputer gives us a 32bit number. Some experimenting showed that for the Suunto devies tested the serial number is encoded in that 32bit number: It so happens that the Suunto serial number strings are strings that have all numbers, but they aren't *one* number. They are four bytes representing two numbers each, and the "23500027" string is actually the four bytes 23 50 00 27 (0x17 0x32 0x00 0x1b). And libdivecomputer has incorrectly parsed those four bytes as one number, not as the encoded serial number string it is. So the value 389152795 is actually hex 0x1732001b, which is 0x17 0x32 0x00 0x1b, which is - 23 50 00 27. This should be done by libdivecomputer, but hey, in the meantime this at least shows the concept. And helps test the XML save/restore code. It depends on the two patches that create the whole "device.c" infrastructure, of course. With this, my dive file ends up having the settings section look like this: <divecomputerid model='Suunto Vyper Air' deviceid='d4629110' serial='01201094' firmware='1.1.22'/> <divecomputerid model='Suunto HelO2' deviceid='995dd566' serial='23500027' firmware='1.0.4'/> where the format of the firmware version is something I guessed at, but it was the obvious choice (again, it's byte-based, I'm ignoring the high byte that is zero for both of my Suuntos).

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.

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.

2012-12-28Don't match existing dives by date if the dive computers are known to be ↵Gravatar Linus Torvalds
different When downloading from a dive computer, we fall back on matching the exact date of the dive if we can't tell whether we already have that exact dive computer data some other way. However, if you have multiple dive computers and they are sufficiently well synchronized, they might actually have the exact same date, despite the fact that we do want to download both dive computers. We do check the dive start to the exact second, so this sounds unlikely, but with dive computers rounding time to the next minute etc, it's not as unlikely as you'd think. Dirk hit it. So when we match against date, do check that the dive computer might actually be one we've already downloaded from. If we have full model information, we can dismiss the "match date" logic.

2012-12-11Update to the new deco / ndl code in libdivecomputerGravatar Dirk Hohndel
Early in the libdivecomputer 0.3 development cycle Jef and I implemented deco and ndl as events. That wasn't a wise design choice and we agreed to switch this to be instead new sample types which makes much more sense (and is much more aligned with the way we are handling them inside Subsurface). So this commit tracks the change in libdivecomputer. Since this happened during the development cycle there isn't a way to detect this at compile time - so you need to make sure you have a matching version of libdivecomputer when compiling Subsurface. To make this easier: this commit of Subsurface requires a libdivecomputer version that includes the libdivecomputer commit d5d44c1e0ffd "Convert decostop / ndl to samples".

2012-12-04Improve deco handling and add NDL supportGravatar Dirk Hohndel
This commit changes the code that was recently introduced to deal with deco ceilings. Instead of handling these through events we now store the ceiling (which in reality is the deepest deco stop with all known dive computers) and the stop time at that ceiling in the samples. This also adds support for NDL (non stop dive limit) which both dive computers that appear to give us ceiling / deco information appear to give us as well (when the diver isn't in deco). If the mouse hovers over the profile we now add support for displaying the NDL, the current deco obligation and (if we are able to tell from the data) whether we are at a safety stop.

2012-11-28Updating events for libdivecomputer 0.3 (and tracking uemis support)Gravatar Dirk Hohndel
I was a little too eager to add the deco feature to Subsurface. Jef and I went back and forth a few more times and the definition of those events changed. I guess I shouldn't have commited that code until the corresponding libdivecomputer code had been pushed. This commit now brings us in sync with the current master of libdivecomputer (but should compile with 0.2 as well - only deco events won't work then). One issue that I see is that deco / ndl aren't really a good fit for the event model. I actually disabled the drawing of the little yellow triangles for ndl events as for example on the Uemis those events are created whenever the remaining non stop time changes - and that can be every few seconds. The correct solution may be to treat this as a function of the samples, but for now this works and is tested with both OSTC and Uemis SDA. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
