2018-04-27Create one function to determine the supported transportsGravatar Dirk Hohndel
This should make sure we create a consistent view based on all the information available. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
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.

2017-07-09QML UI: add dev_info data to AppLogGravatar Dirk Hohndel

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.

2017-06-22Convert to new libdivecomputer custom IO modelGravatar Linus Torvalds
Instead of being "custom serial", it's a IO model that allows serial or packet modes, independently of each other (ie you can have a bluetooth device that does serial over BT rfcomm and packet-based communication over BLE GATT with the same serial operations that describe both cases).

2017-01-12Stop accessing the internals of dc_descriptor_tGravatar Anton Lundin
This removes our own declaration of dc_descriptor_t and all our accesses to its internals, and switches to use the libdivecomputer functions to access those instead. Signed-off-by: Anton Lundin <glance@acc.umu.se>

2016-09-17Rewrite libdivecomputer custom serial codeGravatar Anton Lundin
This rewrites the custom serial code to use the new api which I implemented in the Subsurface-branch of libdivecomputer. This is a bit to big patch but I haven't had the time to break it down into more sensible patches. This rewrite enables us to support more ftdi based divecomputer communication and is tested with both a OSTC3, OSTC2N and a Suunto Vyper, all over the libftdi driver. The bluetooth code paths are tested to, and should work as before. Signed-off-by: Anton Lundin <glance@acc.umu.se> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2016-04-04Move subsurface-core to core and qt-mobile to mobile-widgetsGravatar Dirk Hohndel
Having subsurface-core as a directory name really messes with autocomplete and is obviously redundant. Simmilarly, qt-mobile caused an autocomplete conflict and also was inconsistent with the desktop-widget name for the directory containing the "other" UI. And while cleaning up the resulting change in the path name for include files, I decided to clean up those even more to make them consistent overall. This could have been handled in more commits, but since this requires a make clean before the build, it seemed more sensible to do it all in one. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
