The 'preexisting' value is used for downloading dives: we want to add
new dives but, but then compare those new dives against the
preexisting ones before we start sorting things and possibly merging
them.
However, the value was only updated sporadically, resulting in it
having stale information in it. Which would cause problems
particularly if you deleted dives, so that the preexisting value would
point past the actual existing values!
So just update it unconditionally in dive_list_update_dives(), which
anything that changes the dive list is supposed to call in order to
display the changes anyway.
Also, just for safety, when removing a dive, put NULL in the last dive
table location. Nobody should ever access past the end anyway (this
is enforced by 'get_dive()') but there are places that access the dive
list table directly, and the libdivecomputer download was one of
those. No reason to leave stale dive pointers possibly around for
uses like that.

From that I created the PNG and then that was converted into the

We have several places where we interpolate the depth based on two
samples and the time between them. Some of them use floating point, some
of them don't, some of them meant to do it but didn't.
Just use a common helper function for it. I seriously doubt the floating
point here really matters, since doing it in integers is not going to
overflow unless we're interpolating between two samples that are hours
apart at hundreds of meters of depth, but hey, it gives that rounding to
the nearest millimeter. Which I'm sure matters.
Anyway, we can probably just get rid of the rounding and the floating
point math, but it won't really hurt either, so at least do it
consistently.
The interpolation could be for other things than just depth, but we
probably don't have anything else we'd want to interpolate. But make the
function naming generic just in case.

o) Instead of using gradient factors as means of comparison, I now use
pressure (as in: maximal ambient pressure).
o) tissue_tolerance_calc() now computes the maximal ambient pressure now
respecting gradient factors. For this, it needs to know about the
surface pressure (as refernce for GF_high), thus gets *dive as an
argument. It is called from add_segment() which this also needs *dive
as an additional argument.
o) This implies deco_allowed_depth is now mainly a ambient-pressure to
depth conversion with decorations to avoid negative depth (i.e. no deco
obliation), implementation of quantization (!smooth => multiples of 3m)
and explicit setting of last deco depth (e.g. 6m for O2 deco).
o) gf_low_pressure_this_dive (slight change of name), the max depth in
pressure units is updated in add_segment. I set the minimal value in
buehlmann_config to the equivalent of 20m as otherwise good values of
GF_low add a lot of deco to shallow dives which do not need deep stops
in the first place.
o) The bogus loop is gone as well as actual_gradient_limit() and
gradient_factor_calculation() and large parts of deco_allowed_depth()
although I did not delete the code but put it in comments.
o) The meat is in the formula in lines 147-154 of deco.c. Here is the
rationale:
Without gradient factors, the M-value (i.e the maximal tissue pressure)
at a given depth is given by ambient_pressure / buehlmann_b + a.
According to "Clearing Up The Confusion About "Deep Stops" by Erik C.
Baker (as found via google) the effect of the gradient factors is no
replace this by a reduced affine relation (i.e. another line) such that
at the surface the difference between M-value and ambient pressure is
reduced by a factor GF_high and at the maximal depth by a factor
GF_low.
That is, we are looking for parameters alpha and beta such that
alpha surface + beta = surface + gf_high * (surface/b + a - surface)
and
alpha max_p + beta = max_p + gf_low * (max_p/b + a - max_p)
This can be solved for alpha and beta and then inverted to obtain the
max ambient pressure given tissue loadings. The result is the above
mentioned formula.

As the user enters data into the entry fields, that data is validated and

This commit still has some serious issues.
- when data is input that doesn't validate, we just print a warning to

- when we switch to the last dive in order to show the profile we don't
actually search for the last dive - we just show the first one in the

This comes with absolutely no gui - so the plan literally needs to be
compiled into Subsurface. Not exactly a feature, but this allowed me to
focus on the planning part instead of spending time on tedious UI work.
A new menu "Planner" with entry "Test Planner" calls into the hard-coded
function in planner.c. There a simple dive plan can be constructed with
calls to plan_add_segment(&diveplan, duration, depth at the end, fO2, pO2)
Calling plan(&diveplan) does the deco calculations and creates deco stops
that keep us below the ceiling (with the GFlow/high values currently
configured). The stop levels used are defined at the top of planner.c in
the stoplevels array - there is no need to do the traditional multiples of
3m or anything like that.
The dive including the ascents and deco stops all the way to the surface
is completed and then added as simulated dive to the end of the divelist
(I guess we could automatically select it later) and can be viewed.
This is crude but shows the direction we can go with this. Envision a nice
UI that allows you to simply enter the segments and pick the desired
stops.
What is missing is the ability to give the algorithm additional gases that
it can use during the deco phase - right now it simply keeps using the
last gas used in the diveplan.
All that said, there are clear bugs here - and sadly they seem to be in
the deco calculations, as with the example given the ceiling that is
calculated makes no sense. When displayed in smooth mode it has very
strange jumps up and down that I wouldn't expect. For example with GF
35/75 (the default) the deco ceiling when looking at the simulated dive
jumps from 16m back up to 13m around 14:10 into the dive. That seems very
odd.

The old implementation was broken in several ways.
For one thing the GF values are percentages, so they should normally be
0 < GF < 1 (well, some crazy people like to go above that).
With this most of the Bühlmann config constants were wrong.
Furthermore, after we adjust the pressure tolerance based on the gradient
factors, we need to convert this back into a depth (instead of passing
back the unmodified depth - oops).
Finally, this commit adds closed circuit support to the deco calculations.

There were some minor problems when moving the selection

for the selection to get "stuck" in the middle of the list.
This patch approaches this by always calling
gtk_tree_selection_unselect_all() before
gtk_tree_selection_select_iter(), or simply always making
sure we have one selected iterator when navigating with the keys.
2) When there was a single top level dive before the first trip
it wasn't possible to navigate trough the child dives of said
trip in both directions.
The patch attempts to fix this by having the hunks/checks:
if (idx < 0) {
(idx is of a trip) performed regardless of other conditions.

dives with auto-group on.

This also initializes the N2 tissue saturations to correct numbers
(setting them to zero was clearly silly).
With this commit we walk back in the dive_table until we find a surface
intervall that's longer than 48h. Or a dive that comes after the last one
we looked at; that would indicate that this is a divelist that contains
dives from multiple divers or dives that for other reasons are not
ordered. In a sane environment one would assume that the dives that need
to be taken into account when doing deco calculations are organized as one
trip in the XML file and so this logic should work.
One major downside of the current implementation is that we recalculate
everything whenever the plot_info is recreated - which happens quite
frequently, for example when resizing the window or even when we go into
loup mode. While this isn't all that compute intensive, this is an utter
waste and we should at least cache the saturation inherited from previous
dives (and clear that number when the selected dive changes). We don't
want to cache all of it as the recreation of the plot_info may be
triggered by the user changing equipment (and most importantly, gasmix)
information. In that case the deco data for this dive does indeed have to
be recreated. But without changing the current dive the saturation after
the last surface intervall should stay the same.

In commit 96db56f89c ("Allow overlapping (and disjoint) dive trips")
I allowed dives to be part of arbitrary dive trips regardless of date,
which meant that the divelist tree model code needed to find the right
parent for a dive as it was inserted.
That code stupidly assumed that the top level of the dive list tree
containted *only* trips, which is not at all the case. It happens to
be true if you group all your dives into divetrips (the common case
for autogroup=1, which real users do tend to have), but now that Dirk
made the autogrouping be a per-xml-file setting, it became much easier
to trigger the "mixed trips and non-trip dives" case, and that showed
the stupid bug with the test dives.
So instead of just blindly iterating to the 'n'th entry, search for
the actual entry that is the dive trip we want to associate a dive
with.

This commit steals the cursor up and down keys away from gtk so regardless

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.

We used to have the rule that a dive trip has to have all dives in it in
sequential order, even though our XML file really is much more flexible,
and allows arbitrary nesting of dives within a dive trip.
Put another way, the old model had fairly inflexible rules:
- the dive array is sorted by time
- a dive trip is always a contiguous slice of this sorted array
which makes perfect sense when you think of the dive and trip list as a
physical activity by one person, but leads to various very subtle issues
in the general case when there are no guarantees that the user then uses
subsurface that way.
In particular, if you load the XML files of two divers that have
overlapping dive trips, the end result is incredibly messy, and does not
conform to the above model at all.
There's two ways to enforce such conformance:
- disallow that kind of behavior entirely.
This is actually hard. Our XML files aren't date-based, they are
based on XML nesting rules, and even a single XML file can have
nesting that violates the date ordering. With multiple XML files,
it's trivial to do in practice, and while we could just fail at
loading, the failure would have to be a hard failure that leaves the
user no way to use the data at all.
- try to "fix it up" by sorting, splitting, and combining dive trips
automatically.
Dirk had a patch to do this, but it really does destroy the actual
dive data: if you load both mine and Dirk's dive trips, you ended up
with a result that followed the above two technical rules, but that
didn't actually make any *sense*.
So this patch doesn't try to enforce the rules, and instead just changes
them to be more generic:
- the dive array is still sorted by dive time
- a dive trip is just an arbitrary collection of dives.
The relaxed rules means that mixing dives and dive trips for two people
is trivial, and we can easily handle any XML file. The dive trip is
defined by the XML nesting level, and is totally independent of any
date-based sorting.
It does require a few things:
- when we save our dive data, we have to do it hierarchically by dive
trip, not just by walking the dive array linearly.
- similarly, when we create the dive tree model, we can't just blindly
walk the array of dives one by one, we have to look up the correct
trip (parent)
- when we try to merge two dives that are adjacent (by date sorting),
we can't do it if they are in different trips.
but apart from that, nothing else really changes.
NOTE! Despite the new relaxed model, creating totally disjoing dive
trips is not all that easy (nor is there any *reason* for it to be
easty). Our GUI interfaces still are "add dive to trip above" etc, and
the automatic adding of dives to dive trips is obviously still based on
date.
So this does not really change the expected normal usage, the relaxed
data structure rules just mean that we don't need to worry about the odd
cases as much, because we can just let them be.

We used to enable dive trips whenever we sorted by date, which can be
a bit annoying. Sometimes you really just want to sort all your dives
by date, without necessarily seeing the trip data.
So this changes the default sort to be the "dive number" table, and
then does *not* actually sort by the dive number, but instead enables
the trips, and then sorts the result by date. So the "dive number"
column - which used to be non-sortable - becomes semantically
equivalent to the old date column sorting.
And now sorting by date makes it act like sorting by depth or any
other attribute - we hide the dive trip tree, and just show the plain
list of dives (sorted by date, obviously).

This patch makes a couple of modifications:
1) divelist.c:delete_single_dive() now tries to free all memory associated
with a dive, such as the string values for divemaster, location, notes &
etc.
2) dive.c:merge_text(), now always makes a copy in memory for the returned
string - either combined or one of the two which are passed
to the function.
The reason for the above two changes is that when (say) importing the same
data over and over, technically a merge will occur for the contained dives,
but mapped pointers can go out of scope.
main.c:report_dives() calls try_to_merge() and if succeeds the two dives
that were merged are deleted from the table. when we delete a dive,
we now make sure all string data is cleared with it, but also in the actual merge
itself, which precedes, copies of the merged texts are made (with merge_text()),
so that the new, resulted dive has his own text allocations.

The idea behind editing timestamps had of course been the typical "oops, I

a few hours but keeps the overall order of dives the same).
But reasonable people might argue that they can envision a scenario where
more dramatic changes are being made. And we need to deal with the impact
this has on dive trips.
Here we handle a couple of simple cases:
- this is the only dive in a trip; just update the trip
(this can still cause problems if the new time is in the middle of an
existing trip).
- this dives moves before the start of the trip it is in; let's remove it
from that trip (this response is a bit simplistic - but as I tried to
say, I don't expect this to be a common use case; and removing it at
least doesn't lead to entirely unexpected behavior).
- this dive moves past the end of this trip into the range of a different
trip (in this case we remove the dive from the current trip and allow it
to interrupt the trip it is moving into).

2) Make remember_tree_state() slighly safer. If for example we have recently
deleted a trip from the linked list, it may still exist in the GTK tree model,
thus we want to check when calling find_trip_by_time() if there is an actual
match before setting the "expanded" flag for a trip.
3) When merging two trips in merge_trips_cb(), only use the tree model
to retrieve the timestamps (DIVE_DATE) and then find matching trips with
find_matching_trip(). Once we have pointers to the two trips to be merged,
move dives from one to another iterating with add_dive_to_trip().
4) In merge_trips_cb() - remember the tree state, repopulate the tree and
restore tree state, since now we are not adding/removing rows directly.

Both dives and dive trips have the same 'tripflag' thing, but they are
used very differently. In particular, for dive trips, the only case
that has any meaning is the TF_AUTOGEN case, so instead of having that
trip flag, replace it with a bitfield that says whether the trip was
auto-generated or not.
And make the one-bit bitfields explicitly unsigned. Signed bitfields
are almost always a mistake, and can be confusing.
Also remove a few now stale macros that are no longer needed now that we
don't do the GList thing for dive list handling, and our autogen logic
has been simplified.

This makes the dive trip auto-generation a separate pass from the
showing of the dive trips, which makes things much more understandable.
It simplifies the code a lot too, because it's much more natural to
generate the automatic trip data by walking the dives from oldest to
newest (while the tree model wants to walk the other way).
It gets rid of the most annoying part of using the gtk tree model for
dive trip management, but some still remains.

Prior to this commit, gtk often decided to collapse the trip with the
selected dive after the user imported or downloaded additional dives.
Since Subsurface tracks dives as being selected even after gtk collapses a
trip (which clears all selection state as far as gtk is concerned) this
could lead to the strange situation that the user could click on a new
dive to select it without unselecting the already selected dive - and
suddenly edit or delete did things that were entirely unwanted.
With this change we explicitly save and then restore the tree state around
import and download operations. This ensures that the same dive(s) stay
selected and trips stay expanded and therefore avoids the issues described
here.

If the surface interval between two dives is more than half an hour,

Things like tank refills etc could also be a good thing to check (again,

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.

This introduces the notion of merging two disjoint dives: you can select
two dives from the dive list, and if the selection is exactly two dives,
and they are adjacent (and share the same dive trip), we support the
notion of merging the dives into one dive.
The most common reason for this is an extended surface event, which made
the dive computer decide that the dive was ended, but maybe you were
just waiting for a buddy or a student at the surface, and you want to
stitch together two dives into one.
There are still details to be sorted out: my Suunto dive computers don't
actually do surface samples at the beginning or end of the dive, so when
you stitch two dives together, the profile ends up being this odd "a
couple of feet under water between the two parts of the dive" thing.
But that's an independent thing from the actual merging logic, and I'll
work on that separately.

This adds a couple of helper functions to manage dive trips
("add_dive_to_trip()" and "remove_dive_from_trip()") and makes those
functions do the trip statistics maintenance (trip beginning times,
number of dives, etc).
This was needed because the dive merge cases for multiple dive
computers showed some rather nasty special cases: especially if the
new dive information has been loaded into an XML file with trips
auto-generated, merging several of these kinds of xml files with
multiple dives in several overlapping trips would completely confuse
our previous code.
In particular, auto-generated trips that had the exact same date as
previous trips (because they were generated from the same dive
computer) really confused the code that used the trip timestamp to
manage the trips.
Adding the helper functions allows us to get the general case right
without having to have each piece of code that handles trip
information having to bother about all the odd rules. It will
eventually also allow us to make the dive trip data structures more
logical: right now the dive trip list is largely designed around the
odd gtk model handling, rather than some more higher-level conceptual
relationship with the actual dives.
But for now, this keeps all the data structures unchanged, and just
modifies them using the new helper functions.

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.

This looks like a massive commit mainly because of the line number changes
in the .po files. That sadly hides what really happened here:
- the places where we manually build dates have now been localized
- the one place where we did the English "calculated plural" has been
modified so that it now can be correctly translated (in English this
just adds an 's' to the noun if the number is != 1 - in other languages
this tends to be much more complicated)
I then updated the two German translations to take advantage of the new
constructs. And while I was at it, I changed the translation Trip->Gruppe
to Trip->Reise as that seemed much more appropriate.
I also fixed another error in the German translation where I translated
"dive time" as "Startzeit" - but in the context it was "Dauer".

This is just the first step - convert the string literals, try to catch
all the places where this isn't possible and the program needs to convert
string constants at runtime (those are the N_ macros).
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
over :-)
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
If you do this PLEASE do one commit that just has the new msgid as
changes in line numbers create a TON of diff-noise. Do changes to
translations in a SEPARATE commit.

In divelist.c:get_string(), when truncating the string to a maximum
of 60 characters (to be shown in the divelist), make sure we are
counting in guinchar (sizeof usually 2) instead of gchar (sizeof usually 1).
Use Glib functions such as g_utf8_strlen() and g_utf8_strncpy() to do that.
This patch fixes the potential problem when truncating a UTF-8 string
by calculating its length using strlen() in bytes.
For char = 1 byte, if the length returned by strlen() is an odd number
this means there is at least one single byte length character in there.
But also if the same string has a UTF-8 character at exactly the truncate
position minus x(probably 1) bytes, we are going to split the bytes
forming said UTF-8 char resulting in an incorrect string.

gtk_tree_selection_get_selected_rows is not compatible with older GTK,
while gtk_tree_selection_selected_foreach() should not be used to
modify the tree. A workaround to is allocate memory and store what
is returned from the gtk_tree_selection_selected_foreach() callback
function as a GtkTreeIter array. Once done iterate trought the array
and pass the values to delete_single_dive().
A bit excesive, but it is not certain how safe is modifying the tree
while in the "_foreach" loop, even if it only shows a warning.
On the other hand the GTK source shows gtk_tree_selection_get_selected_rows()
to be a rather complicated and slow method.
Inside delete_single_dive(), once a dive is no longer part of "dive_table"
and if the dive was part of a trip, remove the dive from the tree
(gtk_tree_store_remove()) and call update_trip_timestamp().

however we do potentially create an extra jump and also

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.

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).

This adds the ability to auto create trips from the menu. It's a toggle
entry (and while at it, we made the zoom toggle a toggle entry as well).
We can therfore switch back and forth between auto generated trips.
There is one bug. Assume you have no trips. You manually create a trip
from some dives out of a group of trips that autogen would turn into a
trip. Now you turn on autogen and this trip gets expanded with all the
dives that would normally be grouped together. If you turn off autogen
again, all those dives are still part of the remaining (initially manually
created) trip. Working around this issue seemed a lot more work than the
likelihood of anyone running into it seemed worth.

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...

Fix an issue with trips that have dives from multiple input files
Some simple test dives for the trips code
First cut of explicit trip tracking
The existing code didn't handle the case of different trips for the same
date coming from different sources. It also got confused if the first dive
processed (which is, chronologically, the last dive) happened to be a
"NOTRIP" dive.
This commit adds a bit of debugging infrastructure for the trip handling,
too.

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.

It's an easy thing to do, but the for-loop ends up being pretty ugly, so
hide it behind the macro.
It would be even prettier with one of the (few) useful C99 features:
local for-loop variables. However, gcc needs special command line
options, and other compilers may not do it at all. So instead of doing
#define for_each_dive(_x) \
for (int _i = 0; ((_x) = get_dive(_i)) != NULL; _i++)
we require that the user declare the index iterator too, and the use
syntax becomes
for_each_dive(idx, dive) {
... use idx/dive here ...
}
And hey, maybe somebody actually will want to use the index, so maybe
that's not all bad.

The multi-dive case does fine, but the single-dive case (used when
adding a dive, for example) was somewhat confused between the dive index
(which is the location in the dive array) and the dive number.
Fix this by just passing the dive pointer instead (where NULL means to
use the current dive selection).

Now that the last commit tried to avoid changing the child selections if
the selected group partially matched, we should always [un]select all
children when we actually decide to change something.
Before, it would try to minimize selection damage by stopping
[un]selecting when it hit a child that already matched the selection,
but since we minimize damage differently, the all-or-nothing approach is
better, and gets us sane behavior when the group is collapsed.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
This tries to avoid the problem mentioned in commit972669d6363c ("Rework
dive selection logic"), where a selection of dives hidden by collapsing
the group gets forgotten about by gtk. It does so by always marking the
group selected when it is collapsed with any selected children.
We also avoid selecting new children when a group is selected that
already has at least *some* children selected already. This way we do
minimal damage to existing selections when working with dive group
selections.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
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.
There may be other issues introduced by this too.

This hopefully fixes the common cases. Dirk is cursing gtk. We may
need some gtk selection guru to explain things.
* 'fixes' of git://git.hohndel.org/subsurface:
Another selection fix
More fiddling with the selection
The corner cases are getting more and more artificial. Without this patch,
the following can happen:
Select one or more dives in an (expanded) dive trip. Now collapse that
trip with the little triangle. Select a different trip. The previously
selected dive(s) are still part of the selection (as you can see, for
example, in the statistics tab).
With this patch the scenario above works as intended (all the dives in the
new trip are selected), but we have another corner case:
Just as before, select one or more dives in an expanded dive trip.
Collapse that trip and ctrl-click on another trip. Now you lose the
originally selected dives.
Frankly, if you ctrl-click to add more dives to your selection - just
don't collapse the trips the dives are in?
As this new corner case seems even more artificial than the previous one,
I consider this patch an improvement. But fundamentally I am just battling
all the ways in which gtk's selection handling is messed up. When I get
the selection call back I cannot tell if this is a new selection or an
incremental selection (i.e., a shift-click or ctrl-click).
Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
As expected, this is pretty subtle to get right. But with this change the
code becomes simpler and more straight forward, I think. If the dives in a
group are collapsed, we don't even try to make gtk keep track of their
selection status - we explicitly do so ourselves. This avoids the
artificial expand / collapse around our attempt to force gtk to allow us
to select children that are hidden. But if a dive is expanded, then we
trust gtk to get things right.

Stop relying on gtk to track which dives are selected
We spend way too much effort trying to get gtk to manage the dives that
are selected. The straw that broke the camel's back is that gtk forces us
to expand any nodes that we want to select - so selecting a summary entry
for a dive trip forced us to expand all the dives in the dive trip. Which
as Linus pointed out really sucked from a user experience.
So instead we now completeley ignore gtk's weird idea of what is selected
and what isn't and simply track things ourselves. We still need to play
some games with gtk to make sure that the correct rows are SHOWN as
selected, but still, the overall code seems much cleaner.
This commit contains a bunch of debugging code that is ifdef'ed out -
this is extremely useful to make sure I didn't mess anything up, but
eventually I'll want to remove that again as it just looks ugly in the

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.

We only set up the column specific sort functions for the default (tree)

This commit also somewhat cleans up the handling of selecting summary
lines in the tree model, which includes the very first selection made at
program start (which happens to be the very last dive).
But it still doesn't work the way I expect it to work (i.e., the correct
row is not highlighted). Fundamentally I would prefer clicks on the
summary lines to instead select (or as ctrl-click, possibly deselect) all
the dives under that summary entry. Still TODO.

We keep track of the DIVE_INDEX of all selected dives and simply re-select
those dives after changing model (date based sort or sort by other
column).
There are a few TODOs left. We lose the sort direction (ascending /
descending) when switching models. We also don't correctly deal with the
user selecting summary rows in the tree model.
Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
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.

We now support three hierarchy levels: day, month, and year. Each
indicated by a negative DIVE_INDEX for -1 to -3. This allows a nice

As indicated in the previous commit, things still go wrong with sorting by
other columns as the entries are only sorted within each day, not globally
across the whole dive list.
Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
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
from actual dives. All the data functions are changed so the summary
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.
