This patch centralizes the definition for surface pressure, oxygen in
air, (re)defines all such values as plain integers and adapts calculations.
It eliminates 11 (!) occurrences of definitions for surface pressure and
also a few for oxygen in air.
It also rewrites the calculation for EAD, END and EADD using the new
definitons, harmonizing it for OC and CC and fixes a bug for EADD OC
calculation.
And finally it removes the unneeded variable entry_ead in gtk-gui.c.

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).

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.

When downloading from a dive computer, we fall back on matching the
exact date of the dive if we can't tell whether we already have that
exact dive computer data some other way.
However, if you have multiple dive computers and they are sufficiently
well synchronized, they might actually have the exact same date,
despite the fact that we do want to download both dive computers. We
do check the dive start to the exact second, so this sounds unlikely,
but with dive computers rounding time to the next minute etc, it's not
as unlikely as you'd think. Dirk hit it.
So when we match against date, do check that the dive computer might
actually be one we've already downloaded from. If we have full model
information, we can dismiss the "match date" logic.

Early in the libdivecomputer 0.3 development cycle Jef and I implemented
deco and ndl as events. That wasn't a wise design choice and we agreed to
switch this to be instead new sample types which makes much more sense
(and is much more aligned with the way we are handling them inside
Subsurface). So this commit tracks the change in libdivecomputer. Since
this happened during the development cycle there isn't a way to detect
this at compile time - so you need to make sure you have a matching
version of libdivecomputer when compiling Subsurface.
To make this easier: this commit of Subsurface requires a libdivecomputer
version that includes the libdivecomputer commit d5d44c1e0ffd "Convert

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

I was a little too eager to add the deco feature to Subsurface. Jef and I
went back and forth a few more times and the definition of those events
changed. I guess I shouldn't have commited that code until the
corresponding libdivecomputer code had been pushed.
This commit now brings us in sync with the current master of
libdivecomputer (but should compile with 0.2 as well - only deco events
won't work then).
One issue that I see is that deco / ndl aren't really a good fit for the
event model. I actually disabled the drawing of the little yellow
triangles for ndl events as for example on the Uemis those events are
created whenever the remaining non stop time changes - and that can be
every few seconds.
The correct solution may be to treat this as a function of the samples,
but for now this works and is tested with both OSTC and Uemis SDA.

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

The code pretended to support this for libdivecomputer based downloads,
but it had never been hooked up when the native Uemis downloader was
implemented. When I finally decided to close that feature gap I realized
that the original code was, shall we say, "aspirational" or "completely
bogus" and therefore never worked.
So instead of just hooking up the code for the Uemis downloader I instead
implemented this correctly for the first time for both libdivecomputer and
the native Uemis downloader.
In order not to have to mess with multithreaded Gtk development I simply
opted for a helper function that fires on a 100ms timeout and have it end
the dialog without a response. This way we can run the dialog while
waiting for the download to finish, still update the progress bar and
respond in a useful manner to the user clicking cancel.

The divecomputer download code will stop at a matching dive (unless
you check the "Download all dives" option when downloading).
However, the matching dive is an *exact* match, which works well when
you have a single dive computer, but is a big pain when you have
multiple. What happens is that the date of the dive will be determined
by whatever dive computer you used first, and then downloading from
other dive computers will not match exactly, but will merge (if the
computers are within a minute of each other).
And that will continue to happen every time you try to download from
that other dive computer.
So use the same logic as for the automatic dive merging: consider
"within one minute" to be a matching dive. So don't download dives
that will be merged - unless the user asks for it.
We do want to have some way of saying "force download of all dives
from today" or something like that, I suspect. Because while I don't
want to re-download *every* dive, I might want to force-merge the last

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.

Here is what Linus reported:
I think you have made a mistake in trying to translate some of
libdivecomputer.c
Translating some of those things based on locale is *wrong*, because
they are saved in the XML file.
That covers at least the warnings: they'll get translated when you
import them, and then saved to the XML file as that translation, but
now if you start subsurface in another locale, they will not get
translated back.
So translating XML file contents is fundamentally buggy. It just
shouldn't be done.
So all the "translations" for the event handling are buggy, and
generate crap. Please don't do that. Leave them as English.
And of course he is absolutely right. However, instead of not translating
them at all, this commit fixes things a better way - we now mark the
strings for translation but store the original English strings everywhere
(in the in-memory data structure as well as in the XML file). Only when we
actually display something on the screen (in a tooltip or in the filter
dialog) do we actually translate the strings into the native language.
This should address both Linus' issue and the desire to have localized
event texts.

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

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

enumeration of devices is just the smallest part of it: the constants

So instead of showing just "Parsing dive X", let's show the date of the

libdivecomputer has the absolute worst interfaces to any library *ever*,
and randomly changes those crappy interfaces when it adds support for
new dive computers.
It would have been much better if the interface was just a "open this
device" with a device descriptor structure pointer, so that when Jef
adds support for new devices, the old descriptors still stay around and
work the same way - there's just a new descriptor structure that you
*can* use if you want. Along with a data structure to name the devices
and their descriptors, this would actually mean that users could just
support pretty much any random device that LD supports.
But no, that's not how libdivecomputer works. It has random enums and
crazy different ad-hoc interfaces for different dive computers. Or,
like in this case, crazy different ad-hoc interfaces for the *same*old*
dive computer.
Right now, for example, the support for the new Heinrichs Weikamp "Frog"
computer added a flag to the interface for the old OSTC_2 support.
Breaking any libdivecomputer users even if you didn't need Frog support.
And is there a version number in the header files to check for? Yes,
there's a version number. But no, it's not useful, since it doesn't
actually change with the interface changes. This time, Jef actually did
change the version number (from 0.1.0 to 0.2.0) as part of new
development version, but there's no reason to believe that it will
change in the future as the interfaces change - it never has before.
So it's actually safer - and easier to understand - to check for the
existence of the new header file inclusion mechanism. A new version of
libdivecomputer that supports the HW Frog computer will include the
"ostc_frog.h" header file when you include the libdivecomputer device.h
file, and that will result in HW_FROG_H being defined.
So we can check whether libdivecomputer has the new interface and
supports the Frog by doing an "#ifdef HW_FROG_H" hack. Ugh.

The libdivecomputer interfaces are pure crap. There are no generic
"open the dive computer" or "create a parser for the dive computer"
interfaces, instead each dive computer you support has its own open and
parser generator interface.
And they change. Happily fairly seldom, but they change. And two days
ago, Jef changed the interface for the Mares Icon HD computer in order
to support the newer HD Net Ready variant.
I've asked Jef to make a sane interface for "open the dive computer" and

cannot just track the device model details internally. Which is
obviously a completely bogus claim, since the way *we* track the model
details is to just feed it back from the silly event.
libdivecomputer should just do that internally and not bother us with
its crazy internal model numbers. But whatever.
In the meantime, work around this braindamage, and hope that
libdivecomputer comes to its senses some day.

I don't know about other dive computers, but the Suunto Vyper Air is
slow as hell to import all the dives from. And libdivecomputer seems to
be importing dives "most recent first", so this just makes it stop
importing dives when it finds a dive that we've already seen.
Caveat: libdivecomputer has this fancy notion of "dive fingerprints",
and claims that's the way to do things. That seems to be overly
complicated, and not worth the bother.
If you worry about the import finishing early due to already having some
dives with the same date in your dive list, just import starting from an
empty state, and thus get a pure "dive computer only" state with no
early out. Then you can just load the old dives afterwards, and depend
on subsurface merging any duplicates.
But for normal operation, when you just want to import a couple of new
dives from your dive computer, the "exit import early when you see a
duplicate" is the right thing to do.

Parse them, save them, take them from libdivecomputer.
This doesn't merge them or show them in the profile yet, though.

Ignore surface events - they are meaningless anyway and just add noise.
Print out other events properly, including correct time offset etc.
We still don't actually *save* the events, but now it might be worth
doign so.

As reported by Mauro Dreissig, the progress bar doesn't work and causes
a SIGSEGV due to a missing allocation. The code broke when Dirk
separated out the GUI from the core code, and I hadn't tried
divecomputer downloads since.

The following are UI toolkit specific:
gtk-gui.c - overall layout, main window of the UI
divelist.c - list of dives subsurface maintains
equipment.c - equipment / tank information for each dive
info.c - detailed dive info
print.c - printing
The rest is independent of the UI:
main.c i - program frame
dive.c i - creates and maintaines the internal dive list structure
libdivecomputer.c
uemis.c
parse-xml.c
save-xml.c - interface with dive computers and the XML files
profile.c - creates the data for the profile and draws it using cairo
This commit should contain NO functional changes, just moving code around
and a couple of minor abstractions.

This is the hackiest thing ever, unless you count the previous code that
was even hackier (and just called the gtk main routine at random
places).
The libdivecomputer library is not really set up to be part of the gtk
main loop, and cannot afford (for example) to have lots of mainloop
events while it's parsing. Some dive computers are very timing
sensitive for the communication.
So just start a thread for doing the libdivecomputer stuff, and just
continually call the gtk main loop while that thread is running. I'm
sure we could actually use some gtk signalling thing to make the thread
exit do the right thing, but instead we just poll the status every
100ms.
I did say it was hacky. It does seem to work, though. No more
temporary graying out of the windows when they don't react in a timely
manner because libdivecomputer does some blocking operation.

I never really liked 'diveclog' as a name - it's not like the C part is
all that important. And while I could try to just make up another slang
word for despicable person (in the tradition of naming all my projects
after myself), I just can't see it.
So let's just call it "subsurface".

This is missing a ton of the information in the .SDA files It only
parses the divelog.SDA file, not the dive.SDA file It ignores the
information on the gas(es) used and all the data on the tanks.
It still draws some strange artefacts at the end of the dive
But it correctly hooks into the import dialogue, it gives you a file
select box (somewhere, I'm sure, a gtk developer cries quietly) and then
parses enough of this file to serve as a proof of concept.

It's quite often obvious crap for the "doesn't exist" or "plain air" case.
So if it's reporting 100% O2, we just ignore it. Sure, it could be
right, but for the dives I have I know it's just libdivecomputer being
wrong.
Same goes for obvious crap like 255% Helium.

So this actually reports the dive data that libdivecomputer generates.
It doesn't import special events etc, but neither do we for the xml
importer.
It is also slow as heck, since it doesn't try to do the "hey, I already
have this dive" logic and always imports everything, but the basics are
definitely there.

Instead of writing out the progress events, use them to update a real
progress bar.
Also, we need to handle gtk events while busy with the dive computer
reading. That should *probably* be done with a threading model, because
libdivecomputer does seem to have some timing sensitivity - I'm getting
"failure to read memory block" if I make that loop do the standard
while (gtk_events_pending())
gtk_main_iteration();
thing. Besides, even if we did do that loop, it would still cause
problems when the libdivecomputer code is stuck reading a serial line
that doesn't respond or whatever.
But for now this ugly hack is "good enough" to get further.

This actually gets me far enough that it prints out all the dives on my
dive computer. It doesn't actually turn them into real dives yet,
though - only a series of ugly 'printf's so far.
And it hangs after printing the last dive. So I'm doing something wrong.

.. this now registers the dive parsing callback, and starts to parse the
data. So I can see the last divetime on my Suunto Vyper Air now.
Still a lot more boilerplate stuff to go, though. The libdivecomputer
interfaces really are pretty insane: why should the caller set up the
dive parsing for each computer type, when libdivecomputer knows what
types it has? IOW, much of that boilerplate should be hidden inside of
libdivecomputer, rather than exposed to the user.
But whatever. I'm taking pieces from "examples/universal.c" as I go
along (it's under LGPL 2.1). I want to do it in small chunks just to
feel that I understand what's going on, rather than just blindly copying
it all.

.. start some error reporting, and register some early (empty)
callbacks.
This still doesn't actually do anything. But commit early, commit

this still at least compiled" state.

Ok, so this is quite broken right now: it doesn't actually really *do*
anything, and it now requires that you have libdivecomputer all set up
and installed.
That is fairly easy:
mkdir ../src
cd ../src
git clone git://libdivecomputer.git.sourceforge.net/gitroot/libdivecomputer/libdivecomputer
cd libdivecomputer
autoreconf --install
./configure
make
sudo make install
but you may feel that this is not exactly useful considering that
nothing actually *works* yet.
Some day.
