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.

When we fill the cylinder information in an imperial unit world, a
working pressure of zero is a special case, and forces us to use the
actual physical size of the cylinder in liter, despite the fact that
we normally would use cuft.
However, we compare that value against zero in a 'double', and in
between going through the gtk spinbutton logic, the zero we have
filled in then gets read out as some very tiny epsilon value from the
gtk spinbuttons (typically in the 10**-317 range). This causes us to
think that the zero isn't actually a zero, because gtk has done odd
things with it.
Fix this by calculating the millibar value (as an integer) first, and
check that *integer* against zero. Any crazy epsilon values will have
been rounded away, and our logic works again.
There's a good reason why subsurface does everything using integers
(ie the afore-mentioned "convert to integer millibar" etc) and doesn't
use floating point for any core data structures, only for conversion.
FP rounding and inexact behavior can be really subtle.

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
has been tested with the OSTC and that needs a libdivecomputer patch in
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).

The dive data contains the surface pressure prior to the dive, and that is

The hold_depth field is rather misleading as it normally gives the safety

Based on suggestions from Linus (and a few iterations) we now simply have
the surface (i.e., background color / pattern) come down to where the
ceiling is. And we only do the angry red shading when the diver violates
the ceiling.
I think this looks much better.

When the user closes the divelist and starts with an empty file it makes

Plot a red-shaded area on top of the depth profile to indicate the deco
ceiling (i.e., the area into which it isn't save to ascend at this point
of the dive.
So far this is of very limited use as libdivecomputer doesn't give us the
necessary information to plot this. I have sent patches for the OSTC to
Jef, hoping that he will include them in an update. I don't know how many
other dive computers will make this data available - I still need to add
this to our native Uemis support.

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.

The existing implementation failed on dive computers that did gas changes
based on events (instead of tracking them in the sample data like the
Uemis Zurich does that I tested the code with).
This commit moves the calculations slightly later in create_plot_info()
after the gas change events are processed and the plot_info data has been
fixed up. Now this works with the data from Linus' Suunto as well.

Plotting pO2 / pN2 / PHe
|
|
The pN2 print shouldn't have been committed, but I don't want to try and
rewrite all the commit history. Oh well.
The pressure scale I am ambivalent about. It seems that it should be
useful - but that would require guide lines that coincide with the values
which would really throw off the visual for me. So I added the code, but
left it disabled.

We always want to print absolute maxima and minima - but not when multiple
consecutive data points all have the same value (this happens, for
example, when printing a pHe plot on non-helium dives - or when the dive
profile includes a brief surface intervall which causes all the partial
pressures to be at their minimum).

Whatever I pick here, there will be dives where the different graphs end
up interfering with each other. I don't think there isn't an easy, generic
solution for this (but I can envision awesome non-easy solutions - they
just don't seem to be worth the effort).
But for most dives that I played with this seems to work pretty well.

While the import thread is running it is possible to:
1) click the [x] button of the "download dialog".
To prevent that, we attach a "delete-event" signal to no-op function.
2) to interact with the main window, once the "accept" event is triggered.
To prevent that, we make sure that the window is set back to "modal".

On Windows, device names can end up being <drive-letter> (<drive-label>).
In such a case we are only interested in the <drive-letter> part, when
passing this value to libdivecomputer.
This patch provides a method to trim all text in parentheses and also
any leading and trailing whitespace.
An important addition is enabling back the user to enter a device
manually even it's absent in the combo box list. This device is
then stored and retrieved as the default device, but not stored
in the device list (dc_device_selector()).
As a side effect this change prevents the download dialog closing,
when a user-entered device is not one of the found devices via
subsurface_fill_device_list().

Not sure this is the best naming scheme (General Settings / Tec Settings)
but it's a start.
The idea is to have the settings that a recreational diver might care
about on the first page, and all the other stuff on the second one. Let's
see how this works out long term. For now I moved OTU over and added
toggles for the different partial pressure graphs (only the pO2 one is
implemented so far).

So far this is done unconditionally. This already starts some of the
infrastructure for other gases, but so far only O2 is handled.
We also need a pressure scale on the right to make this useful - or we
need to do peek / trough pressure prints like we do for temperature and
depth.
Finally, I think I want to move the plot further down, maybe make the
whole plot area taller if we are plotting partial gas pressures as well.

subsurface_fill_device_list() now goes trough the list of registry
entries in the SERIALCOMM key and adds all present values (such as
COM1, COM2) to a GtkListStore. Once done the function compares
all logic drive label to a static list of known DC labels,
such a 'UEMISSDA', which is the only present one at the moment
and adds any matching drive letters (e.g. C:\, H:\) to the list store
as well.
If no serial ports were added or no matching logical drives were found
the function simply adds a default entry named "COM1".

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.

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).

We try to identify devices that are connected and their matching device
names (and mount paths in the case of the Uemis Zurich). Those are
presented as a drop down menu to choose from. The user can still override
this by simply entering a different device / path name.
On Windows this is not functional. How do I find out which drive letter
corresponds to the USB device named "UEMISSDA"? Similarly we need code
that finds serial ports that are present. For now we once again default
to COM3 (so this isn't a step back, but of course it's far from what we

With this commit we not only use the getDivelogs command but also the
getDive command for each of the dives that was downloaded. Oddly, that
makes quite a bit of redundant (and at times slightly contradictory) data
available, but also many new things.
We now get weight, suit and notes that were stored with a dive in the
logbook on the divecomputer. There are a ton more data available that we
don't use, yet. For example information about altitude, a decoindex, dive
type and dive activity, other equipment information, etc.
I still need to decide how much of this I want to make available in
Subsurface (and how I want to present this - after all most of this is not
available from other dive computers).
