2018-04-24use libdivecomputer 'fingerprint' to avoid downloading extra dataGravatar Linus Torvalds
This opportunistically uses a cache of 'fingerprints' for already downloaded dives. As we download data from a dive computer, we save the fingerprint and dive ID of the most recent dive in a per-divecopmputer fingerprint cache file. The next time we download from that dive computer, we will load the cache file for that dive computer if it exists, verify that we still have the dive that is referenced in that cachefile, and if so use the fingerprint to let libdivecomputer potentially stop downloading dives early. This doesn't much matter for most dive computers, but some (like the Scubapro G2) are not able to download one dive at a time, and need the fingerprint to avoid doing a full dump. That is particularly noticeable over bluetooth, where a full dump can be very slow. NOTE! The fingerprint cache is a separate entity from the dive log itself. Unlike the dive log, it doesn't synchronize over the cloud, so if you download using different clients (say, your phone and your laptop), the fingerprint cache entries are per device. So you may still end up downloading dives you already have, because the fingerprint code basically only works to avoid duplicate downloads on the same installation. Also, note that we only have a cache of one single entry per dive computer and downloader, so if you download dives and then don't save the end result, the fingerprint will now point to a dive that you don't actually have in your dive list. As a result, next time you download, the fingerprint won't match any existing dive, and we'll resort to the old non-optimized behavior. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2018-04-24Actually tie in the new libdivecomputer IO model to open the dive computer ↵Gravatar Linus Torvalds
device This creates a new libdivecomputer_device_open() helper, and makes downloading and configuration use it to open the dive computer device using the proper protocol. The IRDA case was tested by Sébastien Dugué - I had initially left it undone believing that "nobody uses IRDA".

2018-04-24Convert our custom IO model to new libdivecomputer IO modelGravatar Linus Torvalds
This converts our old custom IO model to the new model that libdivecomputer introduced. This is partly based on Jef's rough patch to make things build, with further work by me. The FTDI code is temporarily disabled here, because it will need to be integrated with the new way of opening devices. The ble_serial code goes away entirely, since now libdivecomputer knows about BLE transport natively, and doesn't need to have any serial wrapper around it.

2018-01-05Increase size of name_buffer to fit any integerGravatar Berthold Stoeger
In libdivecomputer.c, name_buffer is formatted with calls like snprintf(name_buffer, 9, "%d cuft", rounded_size); This works fine in the regular case, but it generates compiler warnings, since theoretically the integer might produce up to 11 digits, leading to a truncation of the string. Increasing the size of name_buffer to 17 chars silences these warnings. This may seem like pointless warning-silencing. Nevertheless, in the case of invalid data, it might make debugging easier since, in the above case, the "cuft" is never truncated. In total, it seems that this is a benign change with potential, though in a very unlikely case, positive effects. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2017-12-13Add pSCR divemode detectionGravatar Jan Mulder
In libdivecomputer, a new divemode is added (DC_DIVEMODE_SCR) useful for dive computers that have specfic functionality for semi-closed rebreathers. At this moment, only the HW computers seem to provide this. This commit takes care of proper recognition of this new divemode when importing data from a dive computer.

2017-12-13Rename DC_DIVEMODE_CC to DC_DIVEMODE_CCRGravatar Jan Mulder
This is just code cleanup. Jef renamed the CCR divemode constant in libdivecomputer, but added a define to be backward compatible as as well (so this rename did not break our Subsurface build). Obviously, this breaks the build for people that build against an older libdivecomputer, but I see no reason to do that. Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>

2017-07-25Make sample pressure helper functions available to everybodyGravatar Linus Torvalds
We had a "add_sample_pressure()" helper functions that was local to just the libdivecomputer downloading code, but it really is applicable to pretty much any code that adds cylinder pressure data to a sample. Also add another helper: "legacy_format_o2pressures()" which checks the sample data to see if we can use the legacy format, and returns the o2 pressure sensor to use for that legacy format. Because both the XML and the git save format will need a way to save the compatible old-style information, when possible, but save an extended format for when we have data from multiple concurrent sensors.

2017-07-25Try to sanely download multiple concurrent cylinder pressuresGravatar Linus Torvalds
This tries to sanely handle the case of a dive computer reporting multiple cylinder pressures concurrently. NOTE! There are various "interesting" situations that this whole issue brings up: - some dive computers may report more cylinder pressures than we have slots for. Currently we will drop such pressures on the floor if they come for the same sample, but if they end up being spread across multiple samples we will end up re-using the slots with different sensor indexes. That kind of slot re-use may or may not end up confusing other subsurface logic - for example, make things believe there was a cylidner change event. - some dive computers might send only one sample at a time, but switch *which* sample they send on a gas switch event. If they also report the correct sensor number, we'll now start reporting that pressure in the second slot. This should all be fine, and is the RightThing(tm) to do, but is different from what we used to do when we only ever used a single slot. - When people actually use multiple sensors, our old save format will start to need fixing. Right now our save format comes from the CCR model where the second sensor was always the Oxygen sensor. We save that pressure fine (except we save it as "o2pressure" - just an odd historical naming artifact), but we do *not* save the actual sensor index, because in our traditional format that was always implicit in the data ("it's the oxygen cylinder"). so while this code hopefully makes our libdivecomputer download do the right thing, there *will* be further fallout from having multiple cylinder pressure sensors. We're not done yet. 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.

2017-06-27Switch over to SSRF_CUSTOM_IO v2Gravatar Linus Torvalds
I hate changing the IO interfaces this often, but when I converted the custom serial interface to the more generic custom IO interface, I intentionally left the legacy serial operations alone, because I didn't want to change something I didn't care about. But it turns out that leaving them with the old calling convention caused extra problems when converting the bluetooth serial code to have the BLE GATT packet fall-back, which requires mixing two kinds of operations. Also, the packet_open() routine was passed a copy of the 'dc_context_t', which makes it possible to update the 'dc_custom_io_t' field on the fly at open time. That makes a lot of chaining operations much simpler, since now you can chain the 'custom_io_t' at open time and then libdivecomputer will automatically call the new routines instead of the old ones. That dc_context_t availability gets rid of all the if (device && device->ops) return device->ops->serial_xyz(..); hackery inside the rfcomm routines - now we can just at open time do a simple dc_context_set_custom_io(context, &ble_serial_ops); to switch things over to the BLE version of the serial code instead. Finally, SSRF_CUSTOM_IO v2 added an opaque "dc_user_device_t" pointer argument to the custom_io descriptor, which gets filled in as the custom_io is registered with the download context. Note that unlike most opaque pointers, this one is opaque to *libdivecomputer*, and the type is supposed to be supplied by the user. We define the "dc_user_device_t" as our old "struct device_data_t", making it "struct user_device_t" instead. That means that the IO routines now get passed the device info showing what device they are supposed to download for. That, in turn, means that now our BLE GATT open code can take the device type it opens for into account if it wants to. And it will want to, since the rules for Shearwater are different from the rules for Suunto, for example. NOTE! Because of the interface change with libdivecomputer, this will need a flag-day again where libdivecomputer and subsurface are updated together. It may not be the last time, either.

2017-03-30Shift fake tank pressures up by 30barGravatar Dirk Hohndel
This is a rather arbitrary value, intended to create actually valid pressure values for Uwatec Memomouse users - since we treat 0bar as invalid pressure value, this simply creates an arbitrary '30bar + delta' to '30bar' consumption graph (since all the Memomouse devices give us is the pressure delta that was used during the dive).

2017-03-29Accept 0 as valid endpressure for Uwatec devicesGravatar Dirk Hohndel
Instead of delivering the actual start and end pressure, memomouse gives you a start pressure that matches the delta between actual start and end pressure, and an end pressure of zero.

We had hardcoded the exact translation of the event numbers. They haven't changed (although we did have what appears to be a spurious entry for "non stop time" at the end that libdivecomputer doesn't have an enum for). Instead, use an explicit array index initializer array, so that it's obvious that the two match up (and if the sample event numbers ever change, we should cope with it gracefully).

2017-01-16Add support for libdivecomputer using DC_SAMPLE_GASMIXGravatar Linus Torvalds
New libdivecomputer versions use DC_SAMPLE_GASMIX to indicate a gas change (which contains the cylinder index we're changing to) rather than SAMPLE_EVENT_GASCHANGE*. Unlike the old GASCHANGE model, and despite the name, DC_SAMPLE_GASMIX does not actually say what the mix is, it only specifies a cylinder index. We had already extended SAMPLE_EVENT_GASCHANGE2 to have the cylinder index in the otherwise unused "flags" field, so this is not all that different from what we used to do. And subsurface internally already had the logic that "if we know what the cylinder index is, take the gas mix from the cylinder data", so we've already been able to transparently use _either_ the actual gas mix or the cylinder index to show the event. But we do want to make it an event rather than some sample data, because we want to show it as such in the profile. But because we are happy with just the cylinder index, we'll just translate the DC_SAMPLE_GASMIX thing to the SAMPLE_EVENT_GASCHANGE2 event, and nothing really changes for subsurface. libdivecomputer has made other changes, like indicating the initial cylinder index with an early DC_SAMPLE_GASMIX report, but we've seen that before too (in the form of early SAMPLE_EVENT_GASCHANGE events), so that doesn't really end up changing anything for us either. HOWEVER, one thing that is worth noticing: do *not* apply this patch and then use an old libdivecomputer library that sends both the DC_SAMPLE_GASMIX samples _and_ the deprecated SAMPLE_EVENT_GASCHANGE events. It will all *work*, but since subsurface will take either, you'll then get duplicate gas mix events. It's not like that is in any way fatal, but it might be a bit confusing.
