2013-01-24Use actual min and max temperatures in statistics.Gravatar Henrik Brautaset Aronsen
The statistics page only used each dive's "watertemp" attribute, regardless of actual higher/lower temperatures in the samples. By finding the actual max/min temperatures, the statistics page utilize more "real" data, and look better even on single dives.

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.

2013-01-22Improve on the "prefer downloaded" dive computer modelGravatar Linus Torvalds
It used to be that when you checked the "Prefer downloaded" checkmark, we'd throw away *any* old dive computer data. That was good, because it allowed us to start from a clean slate when you had some old subsurface data with questionable dive computer data. However, it was a bit extreme, and it's really not what you want if you already have (good) dive computer data from other dive computers. So this modifies the logic a bit. Instead of throwing away all old dive computer data, the "Prefer downloaded" checkmark now means: - the newly downloaded data becomes the "primary" dive computer data (ie the first in the list) - if there was old dive computer data that *could* have been from this new dive computer (ie it didn't have model information, or it had a matching model but no device ID data), we throw that away - but any existing dive computer data from other dive computers is left. This seems to be much closer to what we really would want for a new "preferred" download. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-01-14Centralising and redefining values as integersGravatar Jan Schubert
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. And finally it removes the unneeded variable entry_ead in gtk-gui.c. Jan Signed-off-by: Jan Schubert <Jan.Schubert@GMX.li> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-01-10Split up preference data structure definition into 'pref.h'Gravatar Linus Torvalds
.. and rename the badly named 'output_units/input_units' variables. 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.

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.

2012-12-30Allow overlapping (and disjoint) dive tripsGravatar Linus Torvalds
We used to have the rule that a dive trip has to have all dives in it in sequential order, even though our XML file really is much more flexible, and allows arbitrary nesting of dives within a dive trip. 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.

2012-12-27Small changes in the memory management when dive-mergingGravatar Lubomir I. Ivanov
This patch makes a couple of modifications: 1) divelist.c:delete_single_dive() now tries to free all memory associated with a dive, such as the string values for divemaster, location, notes & etc. 2) dive.c:merge_text(), now always makes a copy in memory for the returned string - either combined or one of the two which are passed to the function. The reason for the above two changes is that when (say) importing the same data over and over, technically a merge will occur for the contained dives, but mapped pointers can go out of scope. main.c:report_dives() calls try_to_merge() and if succeeds the two dives that were merged are deleted from the table. when we delete a dive, we now make sure all string data is cleared with it, but also in the actual merge itself, which precedes, copies of the merged texts are made (with merge_text()), so that the new, resulted dive has his own text allocations.

2012-12-16Properly remove redundant dive computer informationGravatar Linus Torvalds
We had logic to remove duplicate dive computer information after merging dives, but it didn't actually work. Why? Because we had used the 'res' dive computer pointer to traverse the list of dive computers, so it no longer actually pointed to the first dive computer in the result list any more, and so the "remove redundant" code only removed redundant dive computers from a limited and incomplete list. Oops. Also, before checking the whole event and sample list, check if it's the exact same dive computer using our new "match_one_dc()" helper function, and don't even bother checking for sample details if it is.

2012-12-07When merging downloaded dives, strive to keep old dive in 'a'Gravatar Linus Torvalds
This doesn't really change the logic of the merging, but it does mean that the end result tends to be less unexpected: when downloading dives that end up being merged with pre-existing dives (because you have multiple dive computers, for example), the newly downloaded dive data will tend to be appended to the old dive data, rather than showing up first.

2012-12-04Improve automatic dive merging logicGravatar Linus Torvalds
This tunes the heuristics for when to merge two dives together into a single dive. We used to just look at the date, and say "if they're within one minute of each other, try to merge". This looks at the actual dive data, and tries to see just how much sense it makes to merge the dive. It also checks if the dives to be merged use different dive computers, and if so relaxes the one minute to five, since most people aren't quite as OCD as I am, and don't tend to set their dive computers quite that exactly to the same time and date. I'm sure people can come up with other heuristics, but this should make that easier too. NOTE! If you have things like wrong timezones etc, and the divecomputer dates are thus off by hours rather than by a couple of minutes, this will still not merge them. For that kind of situation, we'd need some kind of manual merge option. Note that that is *not* the same as the current "merge two adjacent dives" together, which joins two separate dives into one *longer* dive with a surface interval in between. That kind of manual merge UI makes sense, but is independent of this partical change. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2012-11-25Be much saner about merging dive computer dataGravatar Linus Torvalds
Now that we have dive computer device ID fields etc, we can do a much better job of merging the dive computer data. The rule is - if we actually merge two disjoint dives (ie extended surface interval causing the dive computer to think the dive ended and turning two of those dives into one), find the *matching* dive computer from the other dive to combine with. - if we are merging dives at the same time, discard old-style data with no dive computer info (ie act like a re-download) - if we have new-style dive computers with identifiers, take them all. which seems to work fairly well. There's more tweaking to be done, but I think this is getting to the point where it largely works.

But we keep the function to find the best offset around, because we may well want to use it later when *showing* the dive, and trying to match up the different sample data from the multiple dive computers associated with the dive.

2012-11-21Fix "prefer download" behaviorGravatar Dirk Hohndel
When this was first implemented the assumption was that a downloaded dive that is to be merged with an existing dive would have the same time stamp. But as Linus pointed out even back then, this does fail if a dive has been merged with a download from a different dive computer before (think: download from computer a, then download same dive from b, then improve something in the parsing from computer a and try to redownload; the time stamp could have changed). This commit also fixes a silly omission in the merge_dives() function (which ended up ALWAYS prefering the downloaded dive) and finally implements the necessary changes to mark dives downloaded from a Uemis SDA as well.

2012-11-19When merging non-overlapping dives, add surface events in betweenGravatar Linus Torvalds
Most of the dive computers I have access to don't do the whole surface event thing at the beginning or the end of the dive, so when you merge two consecutive dives, you got this odd merged dive where the diver spent the time in between at a depth of 1.2m or so (whatever the dive computer "I'm now under water" depth limit happens to be). Don't do that. Add surface events at the end of the first dive to be merged, and the beginning of the second one, so that the time in between dives is properly marked as being at the surface. The logic for "time in between dives" is a bit iffy - it's "more than 60 seconds with no samples". If somebody has dive computers with samples more than 60 seconds apart, this will break and we may have to revisit the logic. But dang, that's some seriously broken sample rate.

2012-11-11Add special download modes to force updates from the divecomputerGravatar Dirk Hohndel
This will hopefully not be something we need often, but if we improve support for a divecomputer (either in libdivecomputer or in our native Uemis code or even in the way we handle (and potentially discard) events), then it is extremely useful to be able to say "re-download things from the divecomputer and for things that were not edited in Subsurface, don't try to merge the data (which gives BAD results if for example you fixed a bug in the depth calculation in libdivecomputer) but instead simply take the samples, the events and some of the other unedited data straight from the download". This commit implements just that - a "force download" checkbox in the download dialog that makes us reimport all dives from the dive computer, even the ones we already have, and an "always prefer downloaded dive" checkbox that then tells Subsurface not to merge but simply to take the data from the downloaded dive - without overwriting the things we have already edited in Subsurface (like location, buddy, equipment, etc). This, as a precaution, refuses to merge dives that don't have identical start times. So if you have edited the date / time of a dive or if you have previously merged your dive with a different dive computer (and therefore modified samples and events) you are out of luck.

2012-11-11Support merging of two adjacent divesGravatar Linus Torvalds
This introduces the notion of merging two disjoint dives: you can select two dives from the dive list, and if the selection is exactly two dives, and they are adjacent (and share the same dive trip), we support the notion of merging the dives into one dive. The most common reason for this is an extended surface event, which made the dive computer decide that the dive was ended, but maybe you were just waiting for a buddy or a student at the surface, and you want to stitch together two dives into one. There are still details to be sorted out: my Suunto dive computers don't actually do surface samples at the beginning or end of the dive, so when you stitch two dives together, the profile ends up being this odd "a couple of feet under water between the two parts of the dive" thing. But that's an independent thing from the actual merging logic, and I'll work on that separately.

2012-11-11Simplify and clean up dive trip managementGravatar Linus Torvalds
This adds a couple of helper functions to manage dive trips ("add_dive_to_trip()" and "remove_dive_from_trip()") and makes those functions do the trip statistics maintenance (trip beginning times, number of dives, etc). This was needed because the dive merge cases for multiple dive computers showed some rather nasty special cases: especially if the new dive information has been loaded into an XML file with trips auto-generated, merging several of these kinds of xml files with multiple dives in several overlapping trips would completely confuse our previous code. In particular, auto-generated trips that had the exact same date as previous trips (because they were generated from the same dive computer) really confused the code that used the trip timestamp to manage the trips. Adding the helper functions allows us to get the general case right without having to have each piece of code that handles trip information having to bother about all the odd rules. It will eventually also allow us to make the dive trip data structures more logical: right now the dive trip list is largely designed around the odd gtk model handling, rather than some more higher-level conceptual relationship with the actual dives. But for now, this keeps all the data structures unchanged, and just modifies them using the new helper functions.

2012-11-10Add support for obtaining salinity from libdivecomputerGravatar Dirk Hohndel
This requires a patched libdivecomputer that can return salinity of the water the dive was conducted in. Experimental patches exist that implement this for the OSTC. The code is designed so that it simply defaults to salt water if libdivecomputer doesn't include the feature. The patch also fixes the dive merge code to merge two other recent additions to the dive structure (surface_pressure and visibility). Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-11-10Try to find optimal dive sample merge offsetGravatar Linus Torvalds
When we merge dives where the samples have come from different dive computers, the samples may be offset from each other due to the dive computers not having decided that the dive starts at quite the same time. For example, some dive computers may take a while to wake up when submerged, or there may be differences in exactly when the dive computer decides that a dive has started. Different computers tend to have different depths that they consider the start of a real dive. So when we merge two dives, look for differences in the sample data, and search for the sample time offset that minimizes the differences (logic: minimize the sum-of-square of the depth differences over a two-minute window at the start of the dive). This still doesn't really result in perfect merges, since different computers will give slightly different values anyway, but it improves the dive merging noticeably. To the point that this seems to have found a bug in our Uemis data import (it looks like the Uemis importer does an incorrect saltwater pressure conversion, and the data is actually in centimeter, not in pressure). So there is room for improvement, but this is at least a reasonable approximation and starting point.

2012-11-10Merge branch 'ceiling-plot'Gravatar Dirk Hohndel
This enables plotting the ceiling in deco dives and also adds the necessary code to the uemis importer. The only other dive computer this has been tested with the OSTC and that needs a libdivecomputer patch in order to provide the deco/ceiling information to Subsurface. Fixes #5
2012-11-10Improve logic handling eventsGravatar Dirk Hohndel
We now throw away redundant events, just as we throw away other redundant data coming from the dive computer. Events are considered redundant if they are less than 61 seconds apart and identical. This also improves the display of the remaining events in the profile as we now show the value of the event, if it is present (for example for a deco event we show the duration of the deepest stop). Finally, for events that define a range (so they set the beginning flag and assume and end flag some time later) we no loger show the triangle but assume that some other code handles visualizing them (as happens for the ceiling events).

2012-11-09Fix dive trip merging logicGravatar Linus Torvalds
We used to have very spotty logic for picking the dive trip when merging two dives. It turns out that that spotty logic almost never really matters, because in practice you'll never hit the situation of merging two dives with different dive trips, but it *can* happen. In particular, it happens when you use multiple dive computers, and end up loading the dives from one computer on top of the dives of your other computer. If the clocks of the dive computers was set sufficiently close to each other, the dive merging logic will kick in and you may now have slightly different times for the dives that get merged, and the trip merging logic got *really* confused. The trip management also depends on the trip dates being updated correctly when the dives associated with a trip are updated (whether added or removed), and the trip merging code did none of that. This fixes it all up. Hopefully correctly. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-10-29Fix merging of weight systemsGravatar Linus Torvalds
I just tried downloading some duplicate dives I had on my second dive computer, and it all "just worked" and subsurface merged them for me. Almost perfectly. I say "almost", because in merging them, it threw my old weightsystem data away, due to that not being merged. Also, it was a perfect merge only because the computers are so similar that they just line everything up - same water activation logic, same sample interval, same pretty much everything. So while I know the sample merging is not really the right thing to do (it was designed to get the "merge the exact same dive from the same computer" case right), it worked well enough for this particular case. I'll look at something better later. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2012-10-11Conversion to gettext to allow localizationGravatar Dirk Hohndel
This is just the first step - convert the string literals, try to catch all the places where this isn't possible and the program needs to convert string constants at runtime (those are the N_ macros). Add a very rough first German localization so I can at least test what I have done. Seriously, I have never used a localized OS, so I am certain that I have many of the 'standard' translations wrong. Someone please take over :-) Major issues with this: - right now it hardcodes the search path for the message catalog to be ./locale - that's of course bogus, but it works well while doing initial testing. Once the tooling support is there we just should use the OS default. - even though de_DE defaults to ISO-8859-15 (or ISO-8859-1 - the internets can't seem to agree) I went with UTF-8 as that is what Gtk appears to want to use internally. ISO-8859-15 encoded .mo files create funny looking artefacts instead of Umlaute. - no support at all in the Makefile - I was hoping someone with more experience in how to best set this up would contribute a good set of Makefile rules - likely this will help fix the first issue in that it will also install the .mo file(s) in the correct place(s) For now simply run msgfmt -c -o subsurface.mo deutsch.po to create the subsurface.mo file and then move it to ./locale/de_DE.UTF-8/LC_MESSAGES/subsurface.mo If you make changes to the sources and need to add new strings to be translated, this is what seems to work (again, should be tooled through the Makefile): xgettext -o subsurface-new.pot -s -k_ -kN_ --add-comments="++GETTEXT" *.c msgmerge -s -U po/deutsch.po subsurface-new.pot If you do this PLEASE do one commit that just has the new msgid as changes in line numbers create a TON of diff-noise. Do changes to translations in a SEPARATE commit. - no testing at all on Windows or Mac It builds on Windows :-) Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
