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.

"cur_dc" may be NULL when the XML source isn't a subsurface XML file,
and xml parsing is supposed to use "get_dc()" to pick a dive computer
when the nesting of the XML may not be proper.
Now, XML sources that don't have the proper dive computer nesting
markers generally also do not end up having the extra-data string

Our "get_has_used()" helper only filled in gas usage for cylinders that
had a gas change event associated with them. That works really badly
for things like CCR, but also simply for cases where the dive computer
wasn't necessarily explicitly notified about usage, like sidemount
diving etc.
Just remove the logic. If some use ends up particularly wanting to
ignore some cylinder, they can always do it in the caller instead.

Because of how we traditionally did things, the "o2pressure" parsing
depends on implicitly setting the sensor index to the last cylinder that
was marked as being used for oxygen.
We also always defaulted the primary sensor (which is used for the
diluent tank for CCR) to cylinder 0, but that doesn't work when the
oxygen tank is cylinder 0.
This gets that right at file loading time, and unifies the xml and git
sample parsing to make them match. The new defaults are:
- unless anything else is explicitly specified, the primary sensor is
associated with the first tank, and the secondary sensor is
associated with the second tank
- if we're a CCR dive, and have an explicit oxygen tank, we associate
the secondary sensor with that oxygen cylinder. The primary sensor
will be switched over to the second cylinder if the oxygen cylinder
is the first one.
This may sound backwards, but matches our traditional behavior where
the O2 pressure was the secondary pressure.
This is definitely not pretty, but it gets our historical files working
right, and is at least reasonably sensible.

When we load sample data from a git save-file, we always default to
using the state from the previous sample (except for the special case of
cylinder pressure where an empty value does not mean "same", but
"interpolate", see core/load-git.c: new_sample()).
But the corollary to that is that it's always redundant to save sample
data that hasn't changed since the previous sample.
For some reason, the rbt, bearing and heartrate sample data didn't
follow that rule, and instead saved with lots of extra reduncancy.
(The alternative would be to clear those samples at load time, and make
them act like the pressure data, but it would appear that all these
three values may as well just have the normal "if no change, don't save
them" semantics).

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.

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.

The adapted define was confusingly wrong. Apparently, the BUFSIZ
define was coming from some include file, and was dependent on
platform (Linux 8K, Andorid 1K). Simple rewrite to a new define
and a proper value for both Linux and Android. If 4K is big
enhough, is a little uncertain, as its depends on the read
behavior of all libdivecomputer parsers using this serial
BLE interface.
The buffer size needed (on read, as that is the most prominent
direction when interfacing with DCs) is (most likely) 2x the
maximum block the libdc parsers request at once. I did not
study all parsers, but the Shearwater parser request 20 bytes
at once (we know that from the 1 packet at the time read, we
had before). The OSTC parser request 1K blocks for data
that is longer than 1K (like profiles, header tables).
The 1K we had on Android was working for Shearwater,
Eon Steel, but not for OSTC,as its reads 1K at the time
at max, and overflowing the buffer.
So 32k or 64k seems way to big (as in, much bigger than
any libdc read).

See also b409e9fc91 and 709c1df2af. The OSTC parser
cannot handle reads of single 20 byte BLE packages in serial mode.
Instead of doing a deeper down agressive read, we can read on
the serial level more subtile. As the parser is requesting a
specific number of bytes, we just read that number of bytes and
return them. As the 20 byte BLE packets do (obviously) not
align with the reading requirement of the libdc parser, a little
housekeeing needs to be done in between individual reads.
CAVEAT 1: In contradiction to 709c1df2af, this is supposed to
work for all parsers that properly specify the needed bytes to fetch.

Commit 709c1df2af introduced a hard blocking read for BLE devices.
This did break BLE reads from multiple DCs, and (in hindsight) was not
a correct implementation. It would require, for example, dynamic
read buffers as especially profile data grows with dive time, and
in addition, and more importantly, also the OSTC libdc parser cannot
process the entire profile of a dive at once (but likes to receive
it in 1K blocks). So, basically, it introduced issues, and did not
solve the OSTC read.
This commit reverts this hard blocking read (and as such will break
OSTC BLE reads). But it enables removal of the special cases for
the EON Steel and G2.
A next commit will solve OSTC BLE reads.

Handle credits. Do not just ask for maximum credits all the time as this
will stop the download. Also do not let the credits go back to 0 (while
this might work, this is not tested). Getting back the 0 credits stops
the download, and even when it can be restarted, it is less efficient
(and not needed). Notice also that it takes some time before a grant
request is honoured. During testing I saw reception of up to 25 packets
between request and grant. So a lower bound for the request of
32 packets seems resonable.
One aspect the Telit/Stollmann TIO puzzeled me. Sections 4.1 and 4.2
both talk about credits, but my hyphothesis is that there are two
credits counters in play. One for traffic either way. This commit
only deals with credits granted by Subsurface to the OSTC to send
data. Credits granted by the OSTC to allow Subsurface to send new
commands is NOT part of this commit, and is seemingly not needed
in our scenario. As we only send new commands to the OSTC when
a previous one is finished (per HW's interface spec), the OSTC
does not run out of credits to receive commands.

The current BLE read reads just one 20 bype packet. That packet size is set
in ble_serial_ops, so, without being able to test on anything other than
a OSTC3, I assume that this holds for other BLE DCs too. So, I think is
is weird that those interfaces work with the current read() of just one
packet at the time.
As we need a blocking read (at least for the OSTC parser), just read all
data that is available on the input. And when we think we are done, give
the QtEventloop control to see if there is more, and process that incoming
data as well. All this basically implements a blocking read.
CAVEAT 1: This might break the reading from the currently working BLE devices.
CAVEAT 2: With this, I still cannot read the OSTC3 completely. For
developers familiar with the HW transfer protocol: it just stops while
reading the first full dive (header + profile) command 0x66, despite
correctly reading about 5Kb of data before. For some

1) As the OSTC sends data to the BLE central role (the SSRF client) over 2
characteristics, we have to filter the administrative credit data from
the actual dive data that it received. The characteristcStateChanged
function is adapted for this.
2) We have to be sure that the Terminal Client I/O is fully defined during
opening the connecton to the OSTC. From 6d505b24f0c15 we can see
that the last step in setting up the terminal interface is the grant
of credits. This is done by writing to the proper (the only one, with
id = 0x2902) descriptor of the credits RX characteristic. The here

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.

This seems a bit odd, but it actually has three different reasons for it:
- It's a visual indication of BT LE mode for users
- the rfcomm code only works with legacy BT support, and if we scan a
device that only does LE, we want the custom serial code to instead
automatically fall back on a "emulate serial over LE packets" model.
- we want rfcomm to remain the default for devices that do both legacy
BT _and_ LE, but we want people to have the ability to override the
choice manually. They can now do so by just editing the address
field and adding the "LE:" prefix manually, and it automatically gets
saved for next time.

It also checks "vendor specific" by looking at the UUID string

This changeset fixes 5 issues specific to importing from Liquivision dive logs:
Issue #1: Buffer overrun causes segmentation fault.
At the end of a dive record, untranslatable data is skipped and the file is
scanned for the start of the next dive. This scan was implemented without
regard to buffer size and so the scan ran over the buffer boundary when trying
to scan for the next record after importing the last record in the file.
Issue #2: Incorrect identification of the primary sensor.
The primary tank pressure transmitter was being identified by using the sensor
ID reported in the first pressure event record encountered. When diving with
multiple transmitters (buddy, student, or group transmitters), this is often
not the case and results in the buddy or other group transmitter's pressure
data being imported instead of the primary's.
Through empirical observation of several multi-sensor logs, I identified a
previously unhandled event code (0x10) as marking a sensor identification
event record. Parsing this record allows the primary and other sensors
to be definitively identified regardless of which one sends the first pressure
event.
Issue #3: Sensor values added to the sample collection regardless of sensor ID.
When processing events, the code previously dropped through to create a sample
for every pressure event record, regardless of which sensor ID that event is
associated with. Pressure events for sensors other than the primary are now
ignored and omitted from the sample collection.
Issue #4: Duplicate samples when pressure event time syncs with sample time.
The sample index (d) was not incremented in this specific case resulting in
a duplicate sample (for the same sample time) being created when processing
the next pressure event record.
Issue #5: Unsigned time difference results in erroneous interpolated samples.
When interpolating/extrapolating depth and temperature values for a between-
samples pressure event, a signed time value is subtracted from an unsigned time
value, resulting in an unsigned term. This term is used as a scaling factor
and should be signed to allow for a negative value. Currently, negative values
are instead treated as large unsigned values which result in erroneous scaled
depth and temperature values.

Major functional change in this commit is the addition of found static BT devices

duplication, the btDeviceDiscovered slot is split in two parts, the part to
act as slot for the Qt BT discovery agent (Linux, so mobile-on-desktop), and
the part only needed for Android.
Remaining to be fixed: the correct handling of the QML UI selection of

This adds a central function to convert a BT name to a vendor/product pair
known to Subsurface. This allows interfacing from a paired BT dive
computer, without actively selecting its type, but by selecting it
from the list of paired BT devices. So, after this, downloading from

This seems a very trivial commit, but it is not. It appears that on an Android
build, with defined(Q_OS_ANDROID) the Q_OS_LINUX variable is also defined.
This results in a very tricky discovery process: 1) the JNI stuff pulls the paired
devices from the local BT controller, and 2) The QT discovry agent gets active
BT devices. 1) is a static list, that is, not dependent on actual
visual/discoverable BT devices; it is just cached data from the phone. 2) On
Android, this results in a list of actively visible (paired and not paired)
devices. On desktop, however (with QT/bluez BT stack) the QT discovery agent
just gets the list of paired devices, so more or less equivalent to the situation
described under 1) for Android.
Ok, a long story, but just do not do a discovery on Android at all. Basically,
we need the BT address, device name, and possibly a specific SPP service UUID. This are
fixed and known for HW and Shearwater at this point, so there is no need for a
(lengthy) discovery process, and making sure the the dive computer is discoverable
at the moment the app wants to construct its data to show in the UI. So, the
static list of paired devices is all we need.

This is another attept at the problem if identifying a potentially
user supplied text in the dive notes upon replannig a dive.
It gets rid of the user visable position markers (*!* and ***) and
cirumvents problems with mark-up by first converting the old notes
to plan text (assuming that user only enters plain text in the notes
field as we do in other places as well). Then the automatically added
part is identified by locating the disclaimer in the text (if the user
edited/delted the disclaimer or changed langue in between it is her
problem to manually delete the old plan).
Everything from the disclaimer on is deleted and replaced by the new plan.
If the disclaimer is not found, the new plan is appended to the old notes.

Original issue reported on the mailing list:
The ascent/descent rates are sometimes not what is expected.
E.g. setting the ascent rate to 10m/min results in an actual

This is due to truncating the ascent rate preference,
then effectively rounding up the time to reach each stop to 2s intervals.
The result being that setting the ascent rate to 10m/min

should be removed).
This makes our deco times slightly longer. But in the past,

- avoid re-using a cylinder if the user has manually added pressure
data for it (and the pressures don't match)
- when deciding to reuse a cylinder, make sure that we merge as much of
the type information as makes sense.
This will potentially result in more cylinders that might need manual
cleanup, but at least we won't be throwing out user data. And in most
cases where merging happens, none of this is an issue (because the data
comes fresh from a dive computer, and won't have been manually edited to
trigger the new rules).

The old cylinder merging code depended on the preferred dive having all
the cylinders, and the newly merged dive was just forced to pick from
that existing set of cylinders.
That worked ok if you have a "main" dive computer that you have all the
gases programmed for, and you download that first, and then you download
any secondary data later.
But it completely messed up if the second dive computer had gases that
the first one didn't know about, and just basically ended up doing
random things.
This rewrites the whole thing to actually try to create a union of the
two sets of cylinders when merging, with sane matching so that if the
cylinders match you won't get duplicates.
Miika Turkia hit this when he only used one gas, but had several gases
defined in his OSTC that he downloaded after his Vyper (with had just
the single gas defined).
This should fix that case (at least it does for my xml merging test-case
that showed the same problem after some munging).

In the cylinder table, the last column ("use") always showed
OC-GAS. Editing was enabled, but the user had to guess to enter
a small integer meaning dilluent or CCR oxygen cylingder. I guess,
nobody has ever done that.

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).
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
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.

This adds tooltips for the equipment tab for each cylinder, showing the
amount of gas used.
When you mouse over the size and working pressure fields, the tooltip will
show the amount of gas used (along with start and end gas volumes). And
when you mouse over the start and end pressures, it will show the start
and end gas volumes, and the Z factor used.
I started doing this because of the gas volume questions in the last day
or two (and a few from a few weeks ago). When even Robert Helling starts
wondering about the effects of compressibility on the SAC calculation, our
numbers are clearly too opaque.
With these tooltips, at least you can see what went into the used gas
calculations, instead of having to add debugging options to print out Z
factors.
[ This patch also adds a "rint()" to get the rounding right in the
gas_volume() function. Although rounding to the nearst milliliter
really doesn't matter, it's the right thing to do after doing FP
calculations ;^]

For each stop, this computes an effective gradient factor

to find values for GFlow and GFhigh that give a similar deco

Note that this optimises the average gradient factor. The

the last depth. So we don't necessarily to get the runtime
