Assemble the actual Suunto serial number 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).

Add support for libdivecomputer using DC_SAMPLE_GASMIX 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.

Try to sanely download multiple concurrent cylinder pressures 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>

Preferentially use existing device ID when setting serial number We have two different models for setting the deviceid associated with a dive computer: either take the value from the libdivecomputer 'devinfo' field (from the DC_EVENT_DEVINFO event), or generate the device ID by just hashing the serial number string. The one thing we do *not* want to have, is to use both methods, so that the same device generates different device IDs. Because then we'll think we have two different dive computers even though they are one and the same. Usually, this is not an issue, because libdivecomputer either sends the DEVINFO event or gives us the serial number string, and we'll always just pick one or the other. However, in the case of at least the Suunto EON Steel, I intentionally did *not* send the DC_EVENT_DEVINFO event, because it gives no useful information. We used the serial number string to generate a device ID, and everything was fine. However, in commit d40cdb4755ee ("Add the devinfo event") in the libdivecomputer tree, Jeff started generating those DC_EVENT_DEVINFO events for the EON Steel too, and suddenly subsurface would start using a device ID based on that instead. The situation is inherently ambiguous - for the EON Steel, we want to use the hash of the serial number (because that is what we've historically done), but other dive computers might want to use the DEVINFO data (because that is what _those_ backends have historically done, even if they might also implement the new serial string model). This commit makes subsurface resolve this ambiguity by simply preferring whatever previous device ID it has associated with that particular serial number string. If you have no previous device IDs, it doesn't matter which one you pick. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

Assemble the actual Suunto serial number 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).

Switch over to SSRF_CUSTOM_IO v2 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.
