52050fdc92 Save all dive computer nicknames - whether used or not
We used to save dive computer information only if that dive computer was
actually used in any of the dives we saved.  But we can simplify the
code if we just always save any dive computers we know about.  And it
does allow for some usage cases where you have nicknames for other
peoples computers that you may not actively use, but you want to see if
you end up loading multiple XML files in one go.

So there's just no compelling reason to not just save all the info we
have.  And this will make it less painful to remove the "use system
config for dive computer nicknames", because you can also use this to
continue to gather dive computer info in a separate XML file if you want
to.

b6c9301e58 Move more dive computer filled data to the divecomputer structure
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.

1aa3c0d514 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).

ec38d3708d Move device_info handling into a new 'device.c' file
The legacy nickname wrappers (that use the device_info structure) are
left in gtk-gui.c.  We can slowly start moving away from them, we don't
want to start exporting that thing as some kind of generic interface.

This isn't a pure code movement - because we leave the legacy interfaces
alone, there are a few new interfaces in device.c (like "create a new
device_info entry") that were embedded into the legacy "create nickname"
code, and needed to be abstracted out.

c0ce218df4 Add support to planner to use additional gases during the ascent
This change ended up being quite a bit bigger than expected as it
uncovered a number of bugs in the existing code.

The planner now handles gas changes correctly by creating (and later
parsing) events in the simulated divecomputer. At the end of the dive
specified in the input form the algorithm starts with the deepest
interesting depth: either the first stop below our ceiling or the deepest
depth at which we can change gases. It then traverses all the stop and all
the gas change depth and at each stage ensures that we are allowed to
ascend further before going on.

a58d470bad Remove autogroup from the preferences and store per file instead
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.

d720e133d8 First step in cleaning up cylinder pressure sensor logic
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.

[Dirk Hohndel:  this conflicted with some of my recent changes - I think
		I merged things correctly...]

96db56f89c Allow overlapping (and disjoint) dive trips
We used to have the rule that a dive trip has to have all dives in it in
sequential order, even though our XML file really is much more flexible,
and allows arbitrary nesting of dives within a dive trip.

Put another way, the old model had fairly inflexible rules:

 - the dive array is sorted by time

 - a dive trip is always a contiguous slice of this sorted array

which makes perfect sense when you think of the dive and trip list as a
physical activity by one person, but leads to various very subtle issues
in the general case when there are no guarantees that the user then uses
subsurface that way.

In particular, if you load the XML files of two divers that have
overlapping dive trips, the end result is incredibly messy, and does not
conform to the above model at all.

There's two ways to enforce such conformance:

 - disallow that kind of behavior entirely.

   This is actually hard.  Our XML files aren't date-based, they are
   based on XML nesting rules, and even a single XML file can have
   nesting that violates the date ordering.  With multiple XML files,
   it's trivial to do in practice, and while we could just fail at
   loading, the failure would have to be a hard failure that leaves the
   user no way to use the data at all.

 - try to "fix it up" by sorting, splitting, and combining dive trips
   automatically.

   Dirk had a patch to do this, but it really does destroy the actual
   dive data: if you load both mine and Dirk's dive trips, you ended up
   with a result that followed the above two technical rules, but that
   didn't actually make any *sense*.

So this patch doesn't try to enforce the rules, and instead just changes
them to be more generic:

 - the dive array is still sorted by dive time

 - a dive trip is just an arbitrary collection of dives.

The relaxed rules means that mixing dives and dive trips for two people
is trivial, and we can easily handle any XML file.  The dive trip is
defined by the XML nesting level, and is totally independent of any
date-based sorting.

It does require a few things:

 - when we save our dive data, we have to do it hierarchically by dive
   trip, not just by walking the dive array linearly.

 - similarly, when we create the dive tree model, we can't just blindly
   walk the array of dives one by one, we have to look up the correct
   trip (parent)

 - when we try to merge two dives that are adjacent (by date sorting),
   we can't do it if they are in different trips.

but apart from that, nothing else really changes.

NOTE! Despite the new relaxed model, creating totally disjoing dive
trips is not all that easy (nor is there any *reason* for it to be
easty).  Our GUI interfaces still are "add dive to trip above" etc, and
the automatic adding of dives to dive trips is obviously still based on
date.

So this does not really change the expected normal usage, the relaxed
data structure rules just mean that we don't need to worry about the odd
cases as much, because we can just let them be.

e3ab1c0701 Update deco handling
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.

8d2abc05f6 Remove nickname from divecomputer data structure
Having it there with the model information seemed to make sense but on
second thought it's the wrong spot to keep that information, especially
since we were storing it in the XML file in every single dive.

This change removes the nickname member from the divecomputer and makes

5e5e3460ac Turn latitude and longitude into integer micro-degree values
This actually makes us internally use 'micro-degrees' for latitude and

708df33539 Save latitude/longitude using integer math
I hate using floating point, this tries to at least make parts of it be
integer logic, and avoid the whole locale issue.  This still keeps the
latitude and longitude internally as a floating point value, and parses
it that way, but I'm slowly moving towards less and less FP use.

We're going to use micro-degrees for location information: that's
sufficient to about a tenth of a meter precision, and it fits in a
32-bit integer.

If you specify dive sites with more precision than that, you may have
OCD.

dcb6574dc4 Improve deco handling and add NDL support
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.

1ca1fe7994 Improve on divecomputer data handling
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.

2a78f3436c Fix the XML gps parsing and saving when using non-US locales
The GPS parsing and saving was using sscanf and sprintf respecively, and
since it is using floating point values (boo!) that affects both of

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
for grins, since we don't have a good way to actually set the GPS

01f1ccff14 Add support for visibility tracking and allow manual entry air temp
Turns out we had a data field for visibility as a length unit - but never
used it. I can never guess how much visibility we actually had on a dive -
but I think most everyone can assign a rating between abysmal (zero stars,
"I couldn't read my dive computer even right in front of my mask" - trust
me, I had some of those dives) to amazing ("five stars, I could see farther
than I though possible" - and I had one or two of those, too). So I
changed this to an integer and am re-using the star infrastructure we have
for the overall dive rating.

When displaying this I was dismayed that we are running out of space in
the "Dive Notes" notbook. So I moved this to the "Dive Info" notebook.
This is not consistent and not logical. I think we need to revisit the
notebooks and think about what we want to display where.

While adding the infrastructure to manually enter the visibility I went
ahead and added the ability to manually enter the air temperature as well
(that was one of the things missing in the previous commit).

3244a828f3 New XML format for saving dives
This patch makes the trips nest, and it also fixes the fact that you never
saved the trip notes (you could edit it, but saving would throw it away).

I did *not* change the indentation of the dives, so the trip stuff shows
up the the beginning of the line, at the same level as the <dive> and
<dives> thing. I think it's fairly readable xml, though, and we haven't
really had proper "indentation shows nesting" anyway, since the top-level
"<dives>" thing also didn't indent stuff inside of it.

Anyway, the way I wrote it, it still parses your old "INTRIP" stuff etc,
so as far as I know, it should happily read the old-style XML too. At
least it seemed to work with your xml file that already had the old-style
one (I haven't committed my divetrips, exactly because I didn't like the
new format).

It always saves in the new style, though.

c4c636fb4f Fix missing save of (almost empty) cylinder information
If we have no explicit cylinder info at all (it's normal air, no size or
working pressure information, and no beginning/end pressure information),
we don't save the cylinders in question because that would be redundant.

Such non-saved cylinders may still show up in the equipment list because
there may be implicit mention of them elsewhere, notably due to sample
data, so not saving them is the right thing to do - there is nothing to
save.

However, we missed one case: if there were other cylinders that *did* have
explicit information in it following such an uninteresting cylinder, we do
need to save the cylinder information for the useless case - if only in
order to be able to save the non-useless information for subsequent
cylinders.

This patch does that. Now, if you had an air-filled cylinder with no
information as your first cylinder, and a 51% nitrox as your second one,
it will save that information as

  <cylinder />
  <cylinder o2='51.0%' />

rather than dropping the cylinder information entirely.

This bug has been there for a long time, and was hidden by the fact that
normally you'd fill in cylinder descriptions etc after importing new
dives. It also used to be that we saved the cylinder beginning/end
pressure even if that was generated from the sample data, so if you
imported from a air-integrated computer and had samples for that cylinder,
we used to save it even though it was technically redundant.

We stopped saving redundant air sample information in commit 0089dd8819
("Don't save cylinder start/end pressures unless set by hand").

7fa0399949 Fix dive trip saving bug
When switching the dive trips to be stored in a different data structure I
forgot to update the code in save_trip() - and since we were passing the

dce08deb34 Use a 64-bit 'timestamp_t' for all timestamps, rather than 'time_t'
This makes the time type unambiguous, and we can use G_TYPE_INT64 for it
in the divelist too.

It also implements a portable (and thread-safe) "utc_mkdate()" function
that acts kind of like gmtime_r(), but using the 64-bit timestamp_t.  It
matches our original "utc_mktime()".

ae33b5ef52 Display yearly/monthly statistics
Display yearly statistics in a statistics window with option to expand
the viewing on monthly level. The amount of dives along with basic
information like duration, depth, water temperature and air consumption
is displayed in yearly and monthly level. Thus you are able to compare
e.g. development of air consumption or diving activity from year to
year.

Using already existing macro for splitting seconds into minutes:seconds.
Moving repetitive code to a function (couldn't think of the suggested
clever macro, but this should pretty much do the trick).
Now the statistics are updated every time the process_all_dives function
is called. It might make sense to actually verify the structures need to
be re-allocated, but such optimization is currently not implemented.

In preparation for the next stage of the trips handling this commit makes
the macros used to access trips (and some frequently used variables for
the tree and list models) more consistent.

This also changes the way we display un-grouped dives in the dive list,
i.e. dives that are not part of a dive trip. Their dive number is now
printed bold.

e315abf645 First cut of explicit trip tracking
This code establishes the explicit trip data structures and loads and
saves them in the XML data. No attempts are made to edit / modify the
trips, yet.

Loading XML files without trip data creates the trips based on timing as
before. Saving out the same, unmodified data will create 'trip' entries in
the XML file with a 'number' that reflects the number of dives in that
trip. The trip tag also stores the beginning time of the first dive in the
trip and the location of the trip (which we display in the summary entries
in the UI).

The logic allows for dives that aren't part of a dive trip. All other
dives simply belong to the "previous" dive trip - i.e. the dive trip with
the latest start time that is earlier or equal to the start time of this
dive.

This logic significantly simplifies the tracking of trips compared to
other approaches that I have tried.

The automatic grouping into trips now is an option that defaults to off
(as it makes changes to the XML file - and people who don't want this
feature shouldn't have trips added to their XML files that they then need
to manually remove).

For now you have to select this option, then exit the program and start it
again. Still to do is to trigger the trip generation at run time.

We also need a way to mark dives as not part of trips and to allow options
to combine trips, split trips, edit trip location data, etc.

The code has only had some limited testing when opening multiple files.

The code is known to fail if a location name contains unquoted special
characters like an "'".

This commit also fixes a visual inconsistency in the preferences dialog
where the font selector button didn't have a frame around it that told you
what this option was about.

d96b504bc4 Only quote the quote characters in xml attributes
The quoting of single and double quotes is only necessary for
attributes, and is irritating for other fields in that it makes the
fields almost unreadable in the xml file.  Single quotes in particular
are common, and turning "it's" into "it&apos;s" is just not reasonable
for dive notes etc.

So add a flag to whether the xml quoting is for an attribute or not, and
take that into account.

52748412ff Fix some issues with star rating code
To waste less space in the tree view heading we simply put a star in the

We now treat "zero stars" to mean "not rated" and don't store that value
in the XML file.

property of the dive tag.

af290d5eb2 Add typical 0 to 5 star rating for dives
This works ok-ish, but doesn't allow us to click on the stars and edit
them in the divelist, which a user might expect to be able to do - in
most "star rating UIs" you simply click on the n-th star to set that
rating. Here you need to edit the dive and pick the rating from a drop
down menu.

Minor oddity: you can actually (if you force it) write anything you want
into the star rating. But anything that isn't one of the predefined
strings simply results in a zero star rating.

Overall the UI feels a bit... forced. But I think this is quite useful
anyway.

5c2fca2620 Save cylinder O2/He content after the cylinder type description
This changes the save format xml to be a bit more readable: instead of
putting the gasmix first, put the cylinder type (size, workpressure and
description) first, then gasmix, then pressure details.

It makes no difference for machine parsing, but I think it's a lot more
logical for humans that actually look at the xml file.  And we really do
want to make the xml file readable by humans.

0f9d1757a4 Don't drop precision from floating point GP coordinates
Using '%f' limits the precision to 6 decimals, which may well be
perfectly ok.  But at least in theory you *could* have higher precision,
and gps units will report it, so don't mindlessly limit us to what %f
shows.

This arbitrarily uses '%.12g' instead.  %g will drop excess zeroes at
the end, so it actually results in the same (or shorter) ascii
representation unless you have the extra precision.
