But it still doesn't work the way I expect it to work (i.e., the correct

Create duplicate list model so sorting by columns works again
One major downside of the switch to a tree model is that sorting by
columns other than date was broken - it would sort the entries within each
date which is not all that useful.
After playing with some Gtk trickery that would allow us to filter out
those rows it quickly became clear that the much easier solution is to
simply maintain TWO models (and therefore two storages). This causes some
overhead and requires some careful tracking of all changes, but it turned
out to be rather straight forward to do.
dive_list now has three model related members:
model - current model displayed (which is one of the following two)
treemodel - the tree model
listmodel - the list model
One side effect is that the callbacks no longer can pass the model around
(as this could have changed since the callback was registered), but that
seems only a minor drawback and was easily addressed.
The implementation in this commit still has a couple of obvious flaws:
when switching back from the list model to the tree model all the
expansion state of the rows is lost and we end up with just a list of the
different years visible. Also, selections aren't maintained when switching
models.

other columns as the entries are only sorted within each day, not globally
across the whole dive list.

Allow date based grouping
This is the very first rough cut. It switches things over to a tree model
so we can have date based summary nodes.
It uses a DIVE_INDEX of -1 for summary nodes to easily tell them apart

nodes only show the date they cover.
The commit also adds a couple of debug functions to be able to easily peek
into the model from the debugger.
Lots of things left to do. There is no longer a first dive selected when
starting subsurface. Sorting by columns other than date is messed up. We
almost certainly want month and year summary entries as well.

Update for libdivecomputer pkg-config include file changes
Subsurface doesn't compile on OS X any more, because libdivecomputer
changed the way the header inclusion works: the include path from
pkg-config no longer includes the final "libdivecomputer" component, and
instead of doing
#include <header.h>
for libdivecomputer headers, we're now supposed to do
#include <libdivecomputer/header.h>

The reason this only bit us on OS X is that I never trusted pkg-config
that much for non-system libraries on Linux (maybe it works, maybe it
doesn't, I've seen it go both ways), so on Linux we just used our own
version of the include path, and thus weren't affected by the

cochran: add support for importing the exported CSV files
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>

Of course, the CSV files really *are* pretty useless, since they don't

Make subsurface compile with current libdivecomputer git tree
libdivecomputer has the absolute worst interfaces to any library *ever*,

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.
Linus found this embarrassing bug: double clicking on a weight system in
order to edit it launched the edit function for the first cylinder

... 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.

cochran: do a partial header de-scramble
This descrambles at least parts of the header data. Some of it has the
same pattern of data 4kB apart, it may be that there is a dive hiding in
there too (ie what I currently call a "header" may in fact be a header
_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.
As with the dive data, there seems to be some offset differences between
different CAN files.

cochran: do the full de-scramble for one case
So this descrambles all the dives in *one* of my cochran test files. I
still don't know what the dive data *means*, but it's not a random
jumble of bytes any more: there are very clear patterns.
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
actual *dive* data starts at 0x45e03, so there's tons of unknown stuff
in the file even outside the dives themselves)

Make cochran debug output a bit easier to use directly

Add some initial cochran CAN file parsing
It's broken, and currently only writes out a debug output file per dive.
I'm not sure I'll ever really be able to decode the mess that is the
Cochran ANalyst stuff, but I have a few test files, along with separate
depth info from a couple of the dives in question, so in case this ever
works I can at least validate it to some degree.
The file format is definitely very intentionally obscured, though.
Annoying. It's not like the Cochran software is actually all that good
(it's really quite a horribly nasty Windows-only app, I'm told).
Cochran Analyst is very much not the reason why people would buy those
computers. So Cochran making their computers harder to use with other
software is just stupid.

Import: always open and read the file before checking the filename extension
Most of the parsers will want the content in memory, so keep them
simple. The fact that the Suunto parser uses "libzip" that has to
re-open the file is annoying and causes us to re-open the file etc.
But it's the odd man out, so don't design the "open_by_filename()"
function around it. Pretty much everybody else will want to avoid
having to cook up their own IO routines.
Also, when reading the file, NUL-terminate the buffer. This allows us
to just treat text files as large strings if we want to, and doesn't
matter for binary files (we still pass in the length explicitly).

First try at converting user-manual to AsciiDoc
You can do "make doc" in the main directory to create the html version,
and if you want to play around with it, do "make show" in the
Documentation subdirectory to start firefox on the end result.
It's by no means perfect, but it gives somewhat reasonable results, and
this is enough initial work for people to play around with, I think.
NOTE! You need "asciidoc" installed to do this: it's a python program,
so it should be pretty easy even on non-Linux platforms. And on Linux,
most distributions package it, so you just have to do something like
yum install asciidoc
to get it (replace with apt-get/zypper/whatever).
Asciidoc can generate other output too (man-pages, LaTeX, etc), maybe
people want to play with that part too.

Move the gasmix cleanups from XML parsing to the generic dive fixup stage
Right now we do certain cylinder info operations only when importing
from an XML file, which is wrong. In particular, we do the "is the
gasmix air" or "what is the standard cylinder name" only at XML read
time, which means that if you import a dive directly from the dive
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
information for us to do the cylinder name lookup anyway, but some do.
And all Nitrox-capable dive computers do have that O2 percentage that
needs cleanup too.

parse-xml: read the file into memory separately
Using xmlParseFile() was simple, but I'm planning on extending the file
parsing past just XML, since we want to be able to import other formats
too. And quite frankly, that means that we'll want to read the file
into memory to look at it before we start parsing it.
We could decide do it by file extensions too, and I'll look at that
approach as well, but regardless of how we do things it's almost
certainly a good idea to do the file access in one place. The XML
parsing might as well happen from a memory buffer instead anyway.
