Making sure the XSL transformation does not occur on Subsurface's old
XML format. A deeper inspection on the XML content is required as
MacDive and Subsurface (old format) have the same root element (dives).

This XSLT converts MacDive logs into Subsurface format. It supports both
the current version and the upcoming version of the log format.
Conversion was not tested with Imperial units as no samples were
available of such logs. Thus functionality with Imperial units is not
guaranteed.
Note that the gear inventory is currently discarded.

This only changes the infrastructure and actually loses functionality as
it no longer does the simplistic "just treat the locations as dives and
merge them".
The new code that does something "smart" with the gps_location_table is
yet to be written. But now we can use the XML parser to put the gps
locations downloaded from the webservice into their own data structure.
In the process I noticed that we never used the two delete functions in
parse-xml.c and removed them.

The "visibility" value in MacDive XML files could be a random
string, while it's a value of 0-5 in Subsurface. Importing an
illegal value (such as "11m") resulted in a segfault from
libpangocairo and an "Invalid UTF-8 string passed to
pango_layout_set_text()".

They happen for CDATA content, where libxml2 turns the CDATA fields into
a child of the parent entry, but without a name.
Now, of course, any sane person would just want to use the CDATA as the
string value of the parent itself, but libxml2 probably does this
insanity for a reason. And the reason is probably that some misguided
people want to *write* XML using libxml2, and then the stupid child node
actually acts as a "now I want you to write this data as CDATA".
Whatever the reason, let's just ignore it. We will just traverse such a
nameless child and be happy, and we'll give the nameless child the name
of the parent. Our XML node matching logic will then never see this
insane nameless child at all, and doesn't have to care.
Our whole XML parsing rule-of-thumb is to take the whole "be strict in
what you output, but generous in what you accept" to its logical
conclusion. Because we will literally accept almost anything, in any
format. You can mix tags or attributes wildly, and youc an use CDATA or
not as you see fit. We just don't care.

Not that we aren't already insanely permissive in parsing just about any
random noise that could _possibly_ be construed as xml and turn it into
a dive, this makes us even laxer.
If somebody wants to have a <date> tag with both date and time, why the
heck not? It's fine. And if it has just the date, that's fine too. And
the date can be in any of several formats. We really don't care, the
more permissive, the better.
We strive to always write beautiful xml, but let's face it, not
everybody else does. If we can turn random line noise into a dive, we
should do so.

The webservice output uses 'name' as the tag for the dive location. This

test24.xml was suddenly recognized as a dive (the parser was triggering on

We save the (more complete) dive computer information in the XML file
with serial numbers and firmware version if we know about them, so using
a complicated string in the system config was redundant and confusing.
So remove that code.
NOTE! Since the dive computer nicknames are now only saved if the XML
file is saved, we also mark the dive list "changed" when we edit the
nicknames. That way we'll be prompted to save things before exiting,
even if we don't actually edit any actual dive data.

We had various hacky historical artifacts in our XML parsing, partly
from our legacy of parsing integer and floating point data separately
(we used to recognize certain import format differences based on whether
the data was in a floating point or integer format). And partly from
trying to do a good job of importing crap from other dive log software.
Anyway, that actually meant that we refused to parse negative numbers,
and we ignored temperatures of zero because some diving log would do
that for missing values.
Both of these actually bit us when parsing our native XML. Of course,
only crazy ice divers would ever notice.

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.

.. 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.

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).

Having two spots to toggle autogroup had always been a clear sign of
insanity. The inconsistent ludicrous semantic of when we remembered the
state of autogroup was even worse.
This finally gets rid of that disaster and drops the autogroup setting
from the preferences and makes it instead a per file property. When you
save a file, it saves the state of the autogroup toggle. This seems much
more useful - you may have files where you want to create trips by
default. And others, where you don't.

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.

I merged things correctly...]

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.

Having it there with the model information seemed to make sense but on

This commit changes the code that was recently introduced to deal with
deco ceilings. Instead of handling these through events we now store the
ceiling (which in reality is the deepest deco stop with all known dive
computers) and the stop time at that ceiling in the samples.
This also adds support for NDL (non stop dive limit) which both dive
computers that appear to give us ceiling / deco information appear to
give us as well (when the diver isn't in deco).
If the mouse hovers over the profile we now add support for displaying the
NDL, the current deco obligation and (if we are able to tell from the
data) whether we are at a safety stop.

This simplifies the vendor/product fields into just a single "model"
string for the dive computer, since we can't really validly ever use it
any other way anyway.
Also, add 'deviceid' and 'diveid' fields: they are just 32-bit hex
values that are unique for that particular dive computer model. For
libdivecomputer, they are basically the first word of the SHA1 of the
data that libdivecomputer gives us.
(Trying to expose it in some other way is insane - different dive
computers use different models for the ID, so don't try to do some kind
of serial number or something like that)
For the Uemis Zurich, which doesn't use the libdivecomputer import, we
currently only set the model name. The computer does have some kind of
device ID string, and we could/should just do the same "SHA1 over the
ID" to give it a unique ID, but the pseudo-xml parsing confuses me, so
I'll let Dirk fix that up.

This also knows how to save and restore multiple dive computers in the

files with multiple dive computers by hand so far.
The dive computer information right now contains (apart from the sample
and event data that we've always had):
- the vendor and product name of the dive computer
- the date of the dive according to the dive computer (so if you change
the dive date manually, the dive computer date stays around)
Note that if the dive computer date matches the dive date, we won't

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

The GPS parsing and saving was using sscanf and sprintf respecively, and
since it is using floating point values (boo!) that affects both of
them. In a C/US locale, we use a period for decimal values, while most
European locales use a comma.
We really should probably just fix things to use integer values (degrees
and nanodegrees?) but this is the simplest fix/workaround for the issue.
Probably nobody ever really noticed until I tested the Swedish locale

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.

The default filename handling is broken in two different ways:
(a) if we start subsurface with a non-existing file, we warn about
the inability to read that file, and then we exit without setting the
default filename.
This is broken because it means that if the user (perhaps by mistake,
by pressing ^S) now saves the file, he will overwrite the default
filename, even though that was *not* the file we read, and *not* the
file that subsurface was started with.
So just set the default filename even for a failed file open.
The exact same logic is true of a failed parse of an XML file that we
successfully opened. We do *not* want to leave the old default
filename in place just because the XML parsing failed, and possibly
then overwriting some file that was never involved with that failure
in the first place. So just get rid of all the logic to push the
filename saving into the XML parsing layer, it has zero relevance at
that point.
(b) if we do replace the default filename with a NULL file, we need
to set that even if we cannot do a strdup() on the NULL.
This fixes both errors.
