5b3e480be3 Added a function to check if specific OS features are available
linux.c, macos.c, windows.c now contain
subsurface_os_feature_available() that can accept an enum type
os_feature_t defined in dive.h.

The function can be useful to check if a specific global feature
is available on a certain OS version.

94c98865a7 Improve on the DivingLog importer a bit
This adds a few fields that we parse, but more importantly it also tries
to dynamically decide if the sample temperatures and pressures are in
imperial or metric units.

Dirk suspects that DivingLog generally always does everything in metric,
and the reason why he has crazy sample data in imperial units (both for
pressure and temperature) may be due to a bug in the early Uemis
importer for DivingLog.

Which would actually make a lot more sense than DivingLog really being
so insane on purpose.

Anyway, Dirk's brother Jurgen seems to have everything in metric units,
which would be much saner.  Maybe we should throw away the support for
insane DivingLog files entirely, since it is possible that the only use
ever of the possible source of that bug was Dirk's use of the Uemis
importer.

But for now, we end up just guessing. Current guesses:

 - water temperature is below 32 dgC, so 32+ degrees is in Fahrenheit.

 - tank pressures are below 400 bar, so higher values than that must be
   psi.

7f5ecb5bb7 Redo the delete dive code
The existing code (both my first single dive delete and then Lubomir's
multi dive delete code) had way too many issues and was just painfully
inefficient.

This new code takes a radically different approach and mostly ignores the
Gtk tree model (as that gets recreated after a delete, anyway) and instead
is linear time on the number of dives in the list. It does do its best to
maintain the existing selection and the expand state of tree model (the
latter isn't possible if we have switched to the list model).

Many thanks to "Lubomir I. Ivanov" <neolit123@gmail.com> for his work on
this - this commit actually contains a few lines out of one of the patches

The implementation contains a major hack that hooks the uemis code into

6ae67f96f8 Update cylinder info properly
The "cylinders_equal()/copy_cylinders()" functions were buggered, and
only checked (and copied) the cylinder type.  That was on purpose, since
you do want to be able to change the type of a cylinder without changing
the gasmix of the cylinder.

HOWEVER, the reverse is also true: you may want to change the gasmix of
a cylinder without changing the type.

So it's not that the type of the cylinder is special - it's that the
type and the gasmix should be considered separately.

Do that properly for the equipment editing case.

c4c636fb4f Fix missing save of (almost empty) cylinder information
If we have no explicit cylinder info at all (it's normal air, no size or
working pressure information, and no beginning/end pressure information),
we don't save the cylinders in question because that would be redundant.

Such non-saved cylinders may still show up in the equipment list because
there may be implicit mention of them elsewhere, notably due to sample
data, so not saving them is the right thing to do - there is nothing to
save.

However, we missed one case: if there were other cylinders that *did* have
explicit information in it following such an uninteresting cylinder, we do
need to save the cylinder information for the useless case - if only in
order to be able to save the non-useless information for subsequent
cylinders.

This patch does that. Now, if you had an air-filled cylinder with no
information as your first cylinder, and a 51% nitrox as your second one,
it will save that information as

  <cylinder />
  <cylinder o2='51.0%' />

rather than dropping the cylinder information entirely.

This bug has been there for a long time, and was hidden by the fact that
normally you'd fill in cylinder descriptions etc after importing new
dives. It also used to be that we saved the cylinder beginning/end
pressure even if that was generated from the sample data, so if you
imported from a air-integrated computer and had samples for that cylinder,
we used to save it even though it was technically redundant.

We stopped saving redundant air sample information in commit 0089dd8819
("Don't save cylinder start/end pressures unless set by hand").

c804c4e02e Partial rewrite of the dive trip code
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.

It also implements a portable (and thread-safe) "utc_mkdate()" function

d14932058f Fix some of the problems reported by cppcheck
Thanks to Christian for running the static code analysis tool against
subsurface...

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.

41d3a11ee3 Fix a long standing bug when editing dives
Calling edit from the context menu creates a combined editing widget that
contains both dive info and equipment. When editing cylinders or
weightsystems from that widget and confirming those edits with OK those
changes were already committed to the current_dive - regardless on which
dive the user clicked. Worse, even when the user clicked Cancel in the
edit widget, any changes to the equipment stayed in effect.

This had especially confusing consequences when editing multiple dives.

As a workaround this commit adds a global edit_dive variable. This fake
dive is edited by the secondary editing widgets and if the user accepts
changes with OK then they are copied over to the current dive (or all
selected dives in multi dive editing mode).

b49b081bb9 Handle new dives correctly if trips exist
There is an interesting issue when adding new dives into a dive list with
existing trips. Since fill_dive_list walks the list backwards and trips
are determined by the timestamp of the first dive in a trip, it is
non-trivial to know when a dive is added if it should be part of an
existing trip or not. Let's say when we see the dive we can also see a
trip entry that starts four days earlier. Without looking forward in the
list of dives we cannot tell if this is a multi-day trip that this dive
would fit into, or if there is a break of more than tree days (our current
trip threshold).

Instead this commit adds a second scan of the dives in chronological order
that does the right thing for new dives.

c3debc10fd Allow modification and edits of trips
Now that we can load and store trips we needed to add the capability to
manipulate those trips as well.

This commit allows us remove a dive from a trip via a right click
operation on the dive list.

The commit also adds code to split a trip into two, to merge two trips and
to create a new trip out of a top level dive.

To make all that useful this commit changes the right-click on the dive
list to identify and act on the record we are actually on (instead of
acting on the selection).

The right-click menu ("context menu") changes depending which divelist
entry the mouse pointer is on - so different operations are offered,
depending on where you are.

We also add simplistic editing of location and notes for a trip (but the
notes are never displayed so far).

To make our lives easier this commit adds a link from the dive to the dive
trip it is part of. This allowed to hugely simplify the auto trip
generation algorithm (among other things). The downside of this change is
that there are now three different ways in which we express the
relationship of dives and trips: in the dive_trip_list, in the tree_model,
and with these pointers.  Somehow this screams that I should rethink my
data structures...

e315abf645 First cut of explicit trip tracking
This code establishes the explicit trip data structures and loads and
saves them in the XML data. No attempts are made to edit / modify the
trips, yet.

Loading XML files without trip data creates the trips based on timing as
before. Saving out the same, unmodified data will create 'trip' entries in
the XML file with a 'number' that reflects the number of dives in that
trip. The trip tag also stores the beginning time of the first dive in the
trip and the location of the trip (which we display in the summary entries
in the UI).

The logic allows for dives that aren't part of a dive trip. All other
dives simply belong to the "previous" dive trip - i.e. the dive trip with
the latest start time that is earlier or equal to the start time of this
dive.

This logic significantly simplifies the tracking of trips compared to
other approaches that I have tried.

The automatic grouping into trips now is an option that defaults to off
(as it makes changes to the XML file - and people who don't want this
feature shouldn't have trips added to their XML files that they then need
to manually remove).

For now you have to select this option, then exit the program and start it
again. Still to do is to trigger the trip generation at run time.

We also need a way to mark dives as not part of trips and to allow options
to combine trips, split trips, edit trip location data, etc.

The code has only had some limited testing when opening multiple files.

The code is known to fail if a location name contains unquoted special
characters like an "'".

This commit also fixes a visual inconsistency in the preferences dialog
where the font selector button didn't have a frame around it that told you
what this option was about.

21fd73515f Ignore Nitrox/He seetings when editing cylinders for multiple dives
When figuring out which cylinders to change in a multi-dive edit, we
already ignored the beginning and end pressures. But it turns out to make
more sense to also ignore the Nitrox / Helium settings.

Imagine you do a number of dives - for some reason your dive computer
records the wrong cylinder size in the downloaded logfile (like my uemis
does all the time). Dives will likely have different Nitrox percentage,
but you should still be able to simply fix the cylinder size for all dives
at once.

we require that the user declare the index iterator too, and the use
syntax becomes

	... use idx/dive here ...
   }

And hey, maybe somebody actually will want to use the index, so maybe

972669d636 Rework dive selection logic
This completely changes how we keep track of selected dives: instead of
having an array listing the selection ("selectiontracker") or trusting
the gtk selection information, just save the information about whether a
dive is selected in the dive itself.

That makes it trivial to keep track of the state of selection across
group collapse/expand events, or when changing the tree view model.  It
also ends up simplifying the code and logic in other ways.

HOWEVER, it does currently (re-)introduce an annoying oddity with gtk:
if you collapse a dive trip that has individual selections, gtk will
forget those selections ("out of sight, out of mind"), and when you do
*new* selections, the old hidden ones remain.

So there's some games required to make gtk do sane things.  We may need
to either explicitly drop selections when collapsing trips, or make sure
the group entry gets selected when collapsing a group that has
selections in it. Or something.

621761233b Redo dive editing
This commit addresses two issues:

We now can add / edit / delete equipment from the edit dive dialog

We now can edit multiple dives at once

The latter feature has some interesting design constraints:
It picks the 'selected_dive' as the one to start the edit from - so if
this dive already has some information filled in, that information needs
to be overwritten before it is stored in all of the dives. Similarly, only
changes to the cylinders or weightsystems are recorded. Also, the notes
field is not editable in the multi dive edit mode (as that didn't seem
useful).

The workflow seems to work best if using the multi-edit right after
importing new dives from a dive computer. The user then can select all the
new dives and only needs to edit things like location, divemaster, buddy,
weights, etc. once.

This commit will create some obvious conflicts with the commit that adds
exposure protection tracking. It was implemented on top of the tree_view
changes as it reuses some of the infrastructure for tracking the selected
dives.

simply referred to as "suit".

Add the fields to the data structures, add the column to the dive_list

default). Support loading and saving of the suit information.

Display the suit information in the Dive Info pane (this may be a bit

725e4582d9 Don't close config file when changing preferences
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.

1cbe2444cc Add the ugliest 'delete dive' model ever
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.
Thus the "exact same insane interface as the explicit 'Edit' mode".

af290d5eb2 Add typical 0 to 5 star rating for dives
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

0089dd8819 Don't save cylinder start/end pressures unless set by hand
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.

"changed" just because another file was opened.

Import (or adding a file on the command line after --import) means that
you are importing the content of this file to your dive history. So if the
imported file has un-numbered dives that are newer than everything else,
those get correctly renumbered. And importing marks the dive_list as

When importing (or reading xml from files) new dives, we now renumber

NOTE! In order to be "obvious", there can be no overlap between old and
new dives: all the new dives have to come at the end.  That's what
happens with a normal libdivecomputer import, since we cut the import
short when we find a preexisting dive.

But if any of the new dives overlap the old dives in any way, or already
have been numbered separately, the automatic renumbering is not done,
and you need to do a manual renumber.

SDA is a computer and presents a file system when connected via USB - it

does it at the surface), and then perhaps just do the "point browser at
google maps" thing.

Saving/parsing tested by hand-feeding the location of Enenui (Molokini
Crater) from google maps by hand into my divelog.

42f627b8b1 Libdivecomputer: start actually importing the dive data
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.

0c4e1697db Be more careful about unit changes
When we change units, we need to flush any currently active dive
information in the old units, and then carefully reload it in the new
units.

Otherwise crazy stuff happens - like having current cylinder working
pressure values that are in PSI because that *used* to be the output
unit, but then interpreting those values as BAR, because we changed the
units.

Also, since we now properly import working pressure from Diving Log,
stop importing the (useless) cylinder description.  The Diving Log
cylinder descriptions are things like "Alu" or "Steel".  We're better
off just making up our own.

Finally, since Diving Log has cylinder size in metric, make sure that we
do the "match standard cylinder sizes" *after* we've done all the
cylinder size conversions to proper units.

Doing per-dive cylinder start/end pressures is insane, when we can have

And I guess I can see why they'd do that.  But it makes parsing it just

aab4d593bd Generate date string for the dive list dynamically
.. and sort based on the 'time_t' value itself.

This allows us to use a more compact date format that doesn't need to
sort alphabetically, because sorting by date is always based on the date
value.  So we can use just a two-digit year, and skip the seconds, to
keep the column narrow, while still sorting correctly.

Also, "Depth" is a nice header string, but it is wider than the column
itself, which makes the whole column wider than necessary.  So put the
units in the header instead of in the string, keeping things narrow.

5f05173e79 Do a dive de-dup pass
If given multiple dives at the same time, just de-dup the dives.  This
happens when you've dumped the whole dive-computer several times, and
some dives show up in multiple dumps.

When de-duping, try to avoid dropping data.  So if one dive has notes
attached to it, and the other one does not, pick the notes from the dive
that does have them.  Obvious stuff like that.

The sample merge is also written so that it should be possible to merge
two dives. Which we don't actually do yet.

The only thing you can do with that thing is screw things up (like

matter.

9741913124 Start parsing gas mixes
The suunto xml is just completely crazy.  What's the helium percentage
companion to "o2pct"? Would it be "hepct"? No. It's "hepct_0".

Ok, so they didn't number the first o2pct, which could be seen as sane:
that's the only mix value that should always exist.  And they clearly
started their indexing with 0.  So with multiple mixes, you'd then
expect "o2pct_1" and "hepct_1", right?

Wrong! Because XML people are crazy, the second O2 mix percentage is
obviously "o2pct_2".  So the O2 percentages are one-based, with an
implicit one.  But the He percentages are zero-based with an explicit
zero.  So the second mix is "o2pct_2" and "hepct_1".

I'd like to ask what drugs Suunto people are on, but hey, it's a Finnish
company.  No need to ask.  Vodka explains everything.  LOTS AND LOTS OF
VODKA.

In comparison, the libdivecomputer output is nice and sane, and uses a
'gasmix' node.  Of course, now we have so many different XML nesting
nodes to check that I just made it an array of different noces.  That
also allows me to mark the suunto case, so that we only do the "check
for crazy alcoholic xml entries" when it's a suunto file.

The "type of file" thing is probably a good idea for deciding on default
units too. Some day.
