Subject: [PATCH 2/2] Tune the dive joining surface event insert code
So this makes us do surface events only if the samples are more than one
minute apart, and are shallow enough (randomly selected at 5m).
We can add more heuristics. Maybe we should compare the 1-minute sample
time limit of the previous sample to the time to the sample before that:
if some computer (or manually entered dive) has a long time between
*all* samples, we'd make the cut-off time longer.
Baby steps.

This doesn't really change the logic of the merging, but it does mean
that the end result tends to be less unexpected: when downloading dives
that end up being merged with pre-existing dives (because you have
multiple dive computers, for example), the newly downloaded dive data
will tend to be appended to the old dive data, rather than showing up
first.

This actually makes us internally use 'micro-degrees' for latitude and
longitude, and we never turn them into floating point either at parse
time or save time.
That said, the Uemis downloader internally does still use atof() when
converting things, which is likely a bug (locale issues and all that),
but I'll ask Dirk to check it out.

This tunes the heuristics for when to merge two dives together into a
single dive. We used to just look at the date, and say "if they're
within one minute of each other, try to merge". This looks at the
actual dive data, and tries to see just how much sense it makes to
merge the dive.
It also checks if the dives to be merged use different dive computers,
and if so relaxes the one minute to five, since most people aren't
quite as OCD as I am, and don't tend to set their dive computers quite
that exactly to the same time and date.
I'm sure people can come up with other heuristics, but this should
make that easier too.
NOTE! If you have things like wrong timezones etc, and the
divecomputer dates are thus off by hours rather than by a couple of
minutes, this will still not merge them. For that kind of situation,
we'd need some kind of manual merge option. Note that that is *not*
the same as the current "merge two adjacent dives" together, which
joins two separate dives into one *longer* dive with a surface
interval in between.
That kind of manual merge UI makes sense, but is independent of this
partical change.

When picking the "better" trip, we stupidly looked not at the trip
location, but at the _dive_ location.
Which obviously didn't actually pick the "better" trip information at

Now that we have dive computer device ID fields etc, we can do a much
better job of merging the dive computer data.
The rule is
- if we actually merge two disjoint dives (ie extended surface interval
causing the dive computer to think the dive ended and turning two of
those dives into one), find the *matching* dive computer from the
other dive to combine with.
- if we are merging dives at the same time, discard old-style data with
no dive computer info (ie act like a re-download)
- if we have new-style dive computers with identifiers, take them all.
which seems to work fairly well.
There's more tweaking to be done, but I think this is getting to the
point where it largely works.

Also, note that we do *not* do the "find_sample_offset()" any more when
we merge two dives that happen at the same time - since we just keep
both sets of dive computer data around.
But we keep the function to find the best offset around, because we may
well want to use it later when *showing* the dive, and trying to match
up the different sample data from the multiple dive computers associated
with the dive.
Because of that, this causes warnings about the now unused function.

When we have a preferred dive computer that overrides old information
when merging two dives, we just copy the dive computer data over.
However, we need to clear the source of the dive computer data so that
we then don't free the sample data when that old source of the newly
merged dive gets free'd.
This fixes a memory scribble (and likely SIGSEGV) for the "prefer
downloaded" case.

We used to avoid some extra allocations by just allocating the dive
samples as part of the 'struct dive' allocation itself, but that ends up
complicating things, and will make it impossible to have multiple
different sets of samples (for multiple dive computers).
So stop doing it. Just allocate the dive samples array separately.

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
as well.

Most of the dive computers I have access to don't do the whole surface
event thing at the beginning or the end of the dive, so when you merge
two consecutive dives, you got this odd merged dive where the diver
spent the time in between at a depth of 1.2m or so (whatever the dive
computer "I'm now under water" depth limit happens to be).
Don't do that. Add surface events at the end of the first dive to be
merged, and the beginning of the second one, so that the time in between
dives is properly marked as being at the surface.
The logic for "time in between dives" is a bit iffy - it's "more than 60
seconds with no samples". If somebody has dive computers with samples
more than 60 seconds apart, this will break and we may have to revisit
the logic. But dang, that's some seriously broken sample rate.

This will hopefully not be something we need often, but if we improve
support for a divecomputer (either in libdivecomputer or in our native
Uemis code or even in the way we handle (and potentially discard) events),
then it is extremely useful to be able to say "re-download things
from the divecomputer and for things that were not edited in Subsurface,
don't try to merge the data (which gives BAD results if for example you
fixed a bug in the depth calculation in libdivecomputer) but instead
simply take the samples, the events and some of the other unedited data
straight from the download".
This commit implements just that - a "force download" checkbox in the
download dialog that makes us reimport all dives from the dive computer,
even the ones we already have, and an "always prefer downloaded dive"
checkbox that then tells Subsurface not to merge but simply to take the
data from the downloaded dive - without overwriting the things we have
already edited in Subsurface (like location, buddy, equipment, etc).
This, as a precaution, refuses to merge dives that don't have identical
start times. So if you have edited the date / time of a dive or if you
have previously merged your dive with a different dive computer (and
therefore modified samples and events) you are out of luck.

This introduces the notion of merging two disjoint dives: you can select
two dives from the dive list, and if the selection is exactly two dives,
and they are adjacent (and share the same dive trip), we support the
notion of merging the dives into one dive.
The most common reason for this is an extended surface event, which made
the dive computer decide that the dive was ended, but maybe you were
just waiting for a buddy or a student at the surface, and you want to
stitch together two dives into one.
There are still details to be sorted out: my Suunto dive computers don't
actually do surface samples at the beginning or end of the dive, so when
you stitch two dives together, the profile ends up being this odd "a
couple of feet under water between the two parts of the dive" thing.
But that's an independent thing from the actual merging logic, and I'll
work on that separately.

This just re-organizes the dive merging code so that we expose a new
"merge_dives(a, b, offset)" function that merges two dives together into
one with the samples (and events) of 'b' at the specified offset after
'a'.
We'll want to use this if a dive computer has decided that the dive
ended (due to a pause at the surface), but we really want to just turn
the two computer dives into one long one with an extended surface swim.
No functional changes, but some independent cleanups due to the trip

We don't change any of the samples, we just don't plot (or consider for
dive time / mean calculations) the samples at the beginning or end of the
dive that are less than a certain threshold under water. Right now that's
an arbitrary 75cm which seems to Do The Right Thing(tm) for the dives I
tried this with - but I'm happy to look at other values if this causes
problems for people with dive computers I do not have access to.

Add the bookmark and heading events to the list of events not to be
simplified just because they are redundant - in both cases they are
about the user doing something explicit (like the gaschange), so even
if the data is otherwise identical, they should likely be saved.
That said, both events are kind of pointless (we don't actually seem
to save the heading value for the heading events, and bookmarks are
universally just due to user error in at least my case). But still..
This overly aggressive filtering was introduced in commit 6ad73a8f043b

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.

This requires a patched libdivecomputer that can return salinity of the
water the dive was conducted in. Experimental patches exist that implement
this for the OSTC. The code is designed so that it simply defaults to salt
water if libdivecomputer doesn't include the feature.
The patch also fixes the dive merge code to merge two other recent
additions to the dive structure (surface_pressure and visibility).

When we merge dives where the samples have come from different dive
computers, the samples may be offset from each other due to the dive
computers not having decided that the dive starts at quite the same
time.
For example, some dive computers may take a while to wake up when
submerged, or there may be differences in exactly when the dive
computer decides that a dive has started. Different computers tend to
have different depths that they consider the start of a real dive.
So when we merge two dives, look for differences in the sample data,
and search for the sample time offset that minimizes the differences
(logic: minimize the sum-of-square of the depth differences over a
two-minute window at the start of the dive).
This still doesn't really result in perfect merges, since different
computers will give slightly different values anyway, but it improves
the dive merging noticeably. To the point that this seems to have
found a bug in our Uemis data import (it looks like the Uemis importer
does an incorrect saltwater pressure conversion, and the data is
actually in centimeter, not in pressure).
So there is room for improvement, but this is at least a reasonable
approximation and starting point.

This enables plotting the ceiling in deco dives and also adds the
necessary code to the uemis importer. The only other dive computer this

order to provide the deco/ceiling information to Subsurface.

We now throw away redundant events, just as we throw away other redundant
data coming from the dive computer. Events are considered redundant if
they are less than 61 seconds apart and identical.
This also improves the display of the remaining events in the profile as
we now show the value of the event, if it is present (for example for a
deco event we show the duration of the deepest stop).
Finally, for events that define a range (so they set the beginning flag
and assume and end flag some time later) we no loger show the triangle but
assume that some other code handles visualizing them (as happens for the
ceiling events).

We used to have very spotty logic for picking the dive trip when
merging two dives. It turns out that that spotty logic almost never
really matters, because in practice you'll never hit the situation of
merging two dives with different dive trips, but it *can* happen.
In particular, it happens when you use multiple dive computers, and
end up loading the dives from one computer on top of the dives of your
other computer. If the clocks of the dive computers was set
sufficiently close to each other, the dive merging logic will kick in
and you may now have slightly different times for the dives that get
merged, and the trip merging logic got *really* confused.
The trip management also depends on the trip dates being updated
correctly when the dives associated with a trip are updated (whether
added or removed), and the trip merging code did none of that.
This fixes it all up. Hopefully correctly.

I just tried downloading some duplicate dives I had on my second dive
computer, and it all "just worked" and subsurface merged them for me.
Almost perfectly.
I say "almost", because in merging them, it threw my old weightsystem
data away, due to that not being merged.
Also, it was a perfect merge only because the computers are so similar
that they just line everything up - same water activation logic, same
sample interval, same pretty much everything. So while I know the
sample merging is not really the right thing to do (it was designed to
get the "merge the exact same dive from the same computer" case
right), it worked well enough for this particular case. I'll look at
something better later.

This is just the first step - convert the string literals, try to catch
all the places where this isn't possible and the program needs to convert
string constants at runtime (those are the N_ macros).
Add a very rough first German localization so I can at least test what I
have done. Seriously, I have never used a localized OS, so I am certain
that I have many of the 'standard' translations wrong. Someone please take
over :-)
Major issues with this:
- right now it hardcodes the search path for the message catalog to be
./locale - that's of course bogus, but it works well while doing initial
testing. Once the tooling support is there we just should use the OS
default.
- even though de_DE defaults to ISO-8859-15 (or ISO-8859-1 - the internets
can't seem to agree) I went with UTF-8 as that is what Gtk appears to
want to use internally. ISO-8859-15 encoded .mo files create funny
looking artefacts instead of Umlaute.
- no support at all in the Makefile - I was hoping someone with more
experience in how to best set this up would contribute a good set of
Makefile rules - likely this will help fix the first issue in that it
will also install the .mo file(s) in the correct place(s)
For now simply run
msgfmt -c -o subsurface.mo deutsch.po
to create the subsurface.mo file and then move it to
./locale/de_DE.UTF-8/LC_MESSAGES/subsurface.mo
If you make changes to the sources and need to add new strings to be
translated, this is what seems to work (again, should be tooled through
the Makefile):
xgettext -o subsurface-new.pot -s -k_ -kN_ --add-comments="++GETTEXT" *.c
msgmerge -s -U po/deutsch.po subsurface-new.pot
If you do this PLEASE do one commit that just has the new msgid as
changes in line numbers create a TON of diff-noise. Do changes to
translations in a SEPARATE commit.
- no testing at all on Windows or Mac
It builds on Windows :-)

This introduces a new data structure for dive trips - reuseing the struct
dive just got way too messy.
The dive_trip_t datastructure now allows the code to remember if the trip
was auto generated or if its time stamp changed when dives where added to
the trip during auto generation.
The algorithm also distinguishes between dives that were intentionally
added to a trip (either in an XML file or by adding them to trip in the
UI) and dives that were added to trips via autogen. Saving dives that were
added to trips via autogen makes that assignment "intentional".
With this partial rewrite several of the oddities of the old code should
be resolved - especially turning autogen on and off again should get the
divelist back to the previous stage.
Also, when dives are merged during file open or import we now try to pick
the correct tripflag (instead of just ignoring the tripflag completely and
resetting it to TF_NONE by mistake).
Finally, the dive trip debugging code got more verbose and is trying
harder to detect issues at the earliest time possible.

Thanks to Christian for running the static code analysis tool against

There were some false positives, a few style issues that I'll ignore for
now, and two actual potential bugs.
First: Don't check unsigned variables for < 0
This has been around for a while and we are lucky that while technically a
bug it still works as expected. Passing a negative idx simply turns it
into a very large unsigned integer which then fails the > dive_table.nr
test. So it still gets a NULL returned. A bug? Yes. Critical? No.
Mismatched allocation and free
This is an actual bug that potentially could cause issues. We allocate
memory with malloc and free it with g_free. Not good.

Right now we do certain cylinder info operations only when importing

computer, it won't have the air sanitization or the proper default
cylinder names.
Of course, most dive computers don't actually save enough cylinder

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.

I've seen at least DivingLog do this. If you manually enter beginning and
end pressure for a tank it will either linearize the samples in between or
offer to simulate a dive (with constant SAC rate). At least the first case
is reasonably easy to detect. We throw out those samples and ensure that
we still have valid beginning and end pressure for that dive.

At least the Suunto pressure transmitter seems to be pretty
"quantisized", and it will send identical samples for a while until the
pressure changes enough. Then subsurface gives this silly flat line
with a sudden jump downwards, which *could* be you suddenly taking a
deep breath after holding it for a while, but almost certainly it's a
sensor issue.
So just remove successive identical pressure readings. They aren't
interesting, and subsurface will actually do a good job of interpolating
it according to SAC rate instead. And they just make the XML look
worse.

This makes it consider them to be identical if they are within half a
bar of each other. If you edit the pressures by hand and set them to
the same bar pressure as the samples, they may not be identical to the
last milli-bar, but clearly the manually entered cylinder pressure isn't
significantly different from the sample data, so consider it redundant.
We do want manual overrides of cylinder pressures to take precedence
over sample data (as Dirk so eloquently puts it, some dive computers
really don't have very reliable sample data), but at the same time the
sample data is the one we are expecting to be fairly accurate. The
starting and ending pressure overrides are for when there is no sample
data, or when the sample data is totally wrong for some reason.

Keep the sample pressure start/end data separate from the overall
cylinder start/end data - and clean the overall cylinder start/end data
if it matches the samples exactly to avoid the redundancy.
This breaks all the SAC calculations etc, which expect the cylinder
pressures to always be in the cylinder data. I'll fix that up
separately.
The reason for this is that we really want to keep the manually entered
data separate: the pressure plotting doesn't need the confusion, and
considers end-point data (with interpolation) very different from sample
data. Also, we do not want to pollute the xml save-file with data that
is computed.

Finally getting more consistent overall in how we convert between the
different units and how we decide which units to display.

Treat SAC and OTU consistently:
- SAC is now a member of struct dive
- it's calculated / populated at the same time with a helper function with
consistent API
Create get_volume_units function that returns volumes (e.g. used in SAC
rates) based on preferred units - make sure we have these conversions just
once in the code.

Designed along the lines of get_depth_units - except we don't define a
specific number of digits to show.
Use this in the one spot we need it right now in profile.c
