The cochran CSV pressure data is actually in units of '4 psi', not in
just psi. That seems to be the resolution cochran internally keeps
things in, and unlike the depth reading there's no conversion to
standard units in the export (for depth, the quarter-foot depth
resolution is converted to tenths of feet when exporting).
Yeah, none of this makes any sense to me either, but I knew it was the
case. I had just forgotten that factor-of-four when I did the importer.
With this fix, I get the same subsurface data (modulo some rounding
differences particularly for temperature) whether I go through David
McNett's UDDF converter, or just import the CSV data directly.

The Cochran Analyst software can export the basic dive information as
CSV files (comma-separated values).
Individual CSV files contain just one particular type of information:
depth, temperature or cylinder pressure, which is rather inconvenient.
However, the way subsurface works, you can just import these CSV files
all as individual dives, and then subsurface will automatically merge
the dives with the same date and time - and in the process it will also
merge all the samples.
So it turns out that we don't really need any special handling. You can
literally just do
subsurface <list-your-cochran-export-files-here>
and you're all done.
Of course, the CSV files really *are* pretty useless, since they don't
contain all the nice information about where the dive took place etc.
So you literally just get the dive profile. But that's better than
getting nothing at all.
I'd love to actually be able to parse the real native Cochran Analyst
software CAN files, but in the meantime this is at least a starting
point. And if I'm ever able to parse those nasty CAN-files, this makes
comparisons with the exports much easier.

The Cochran CSV depth exports are indeed in tenths of feet, but the
decimal is always 0, 3, 5 or 8. Where the 3 and 8 are obviously 0.25
and 0.75 rounded up to one decimal place.
So Cochran does seem to be very much about imperial units, with depth
and cylinder pressure scaled by four (depth in quarter-foot increments,
pressume in 4-psi increments)

The code is pretty useless, the comments perhaps equally so. I'm trying
to figure out what the data pattern is for the cochran CAN files. There
definitely *is* a pattern, but it actually seems to be different for the
files of different people - and it's not obvious in any case.
There probably are multiple versions of the format, and there might be
things like "David has a high-pressure sensor, and Alex does not" going
on too.

David McNett sent me some example Cochran CAN file data, along with his
UDDF exports of same. I still have absolutely no idea how to decode the

decrypt the data, and I see binary patters rather than just noise), but
at least I can make sure we parse the UDDF portion better.

It is really annoying to have to type the device name each time you need

At the same time, we do want to default to just using the standard

So to allow both testing, and having a nice sane default, just add
support for a SUBSURFACE_XSLT_PATH environment variable that overrides
the default one if it exists.
So then you can just do

Looking at the XML of the two dives Szymon Kosecki sent out to the
subsurface list, I notice that our cylinder size conversion was wrong.
It looks like CYLINDERUNITS is what determines whether the cylinder size
is in metric (0) or imperial (1) units.
Of course, if you gave a cylinder size in cuft and didn't give a working
pressure, subsurface will just ignore the size as the random crap it is.
We *could* default to a working pressure of 3000 psi, of course.
This also picks up the CYLINDERDESCRIPTION value, although neither of
Szymon's dives actually had any description.
I need more SDE xml files to figure out how multi-cylinder dives look
etc, but I think this gets most *simple* SDE files converted almost

I'm hoping most other dive computers are quicker to import from than the
Suunto I have, but mine can take minutes to import all the dives. Sure,
we have that nice progress bar, so it shows that it's doing something,
but it's not really showing *what* it is doing.
So instead of showing just "Parsing dive X", let's show the date of the
dive. That way, when it takes two minutes to import all the dives, at
least you can see "oh, it's going back to the dives of last year" and it
then feels like you have some good reason for the delay.

This partially fixes the second todo entry from commit b0ba22a068

Sadly, the messages that really come from within libdivecomputer itself
(like "suunto_vyper2.c:193: Failed to receive the answer.") when things
go really wrong are not caught. libdivecomputer does have a notion of a

On Linux and MacOS the subsurface_close_conf() doesn't really close the
config file (it flushes writes on MacOS), but on Windows it does
actually close the registry hkey.
Which is bad, if you change the settings multiple times - we assume that
the config file is open the whole time.
So add a "subsurface_flush_conf()" function, and call *that* when
changing configuration parameters. And call the close function only at
the very end.
Alternatively, maybe we should just open the config file separately
every time. I don't much care, maybe somebody else does.

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.

... but only do it if the numbering of subsequent dives was consecutive
to begin with.
Note that we do accept unnumbered dives (and will stop the sequence
check if we find one), but in order to renumber dives on delete, we
require that starting with the dive we delete, the subsequent numbered
dives have to be a nice incrementing series. If that is the case, then
we fix up that numbering as we delete the dive.
Put another way: if the dive numbering was an incrementing sequence
before the delete, then it will be a sane incrementing sequence after it
too. But if you had missing dives before the delete, we will turn the
delete into just another missing dive.
The basic rule is that we never renumber any dives unless that
renumbering is "obviously correct". It's better to leave old numbers
as-is (and expect that the user is going to do an explicit re-numbering
operation) than it is to change dive numbers in a sequence that we don't
understand.
I do suspect that we should possibly check the dive number "backwards"
too, but this doesn't do that.

This interface works the same way the "edit dive" menu item does: it's a
text entry meny item on the dive text entries (ie buddy/divemaster/notes
sections). Except you pick the "Delete" entry rather than the "Edit"
entry.
It kind of works, but it really is a pretty horrible interface. I'll
need to add a top-level dive menu entry for just deleting all selected
dives instead. And it would be good to be able to get a drop-down menu
from the divelist instead of having to do it from the dive text entries,
which is just insane.
But that requires gtk work. I'm not quite ready to get back into that.

It turns out the odd "different CAN files have different header offsets"
came from the fact that the decode block was different lengths, and I
had not picked the correct place to start - and instead had found two
different places that were at different offsets due to the decode block
length differences.
This fixes that up, and it looks like the dive header is correctly
descrambled (but what the data *means* is unclear, although there is now
an ASCII date and time visible, so at least one part of it is pretty
obvious).

same pattern of data 4kB apart, it may be that there is a dive hiding in

_plus_ a dive).
But the 4kB thing may well be an artifact of the crazy scrambling code
itself. Who knows what kind of chunking the Cochran Analyst
"encryption" uses.

However, the magic offsets that work for that particular CAN file are
not generic, because they don't work for another. So there is some
magic dynamic decoding that I don't know about. There is probably more
decode information in the initial decode block, over and beyond just the
scrambling bytes.
(The scrambling array is 234 bytes starting at 0x40001, but the first
