After deleting a dive the dive list is recreated. If there are still dives
selected we should select the last dive as well. If there isn't any dive
selected, then the last dive is as good a default as any, I guess.

Merge the dive trip rewrite by Dirk Hohndel.
This just merges the dive trip changes with the timestamp handling
changes. There were multiple small data conflicts, along with some
newly added 'time_t' cases in the dive trip handling that needed to be
converted to 'timestamp_t' along the way.
* 'divetrip-rewrite' of git://github.com/torvalds/subsurface:
Convert FIND_TRIP into function
Partial rewrite of the dive trip code
Check if trip is NULL before calling DIVE_TRIP
|
|
The pointer size may not be large enough to contain a timestamp, so make
FIND_TRIP() just pass the pointer to the timestamp instead.
And use an inline function instead of macros with casts. That gets us
proper type safety while at it, so that we get a warning if somebody
doesn't pass the expected "timestamp_t *". Plus the code actually looks
simpler and way more straightforward.

This helps us deal with the issue that the g_list convenience functions
don't allow us to easily compare 64bit values on 32bit architectures. And
since these convenience functions are truly trivial in nature, it seemed
easier to simply implement our own logic here.
In the process I moved all the dive_trip_list helper functions into the
same spot in divelist.c

This is the same bugfix that Lubomir did in the master branch, but now
on top of the new 64-bit timestamp_t model. So now we also remove the
comment about the year 2038 problem, because it's not true any more. We
do all the date handling in a 64-bit integer.

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.

This makes the time type unambiguous, and we can use G_TYPE_INT64 for it
in the divelist too.
It also implements a portable (and thread-safe) "utc_mkdate()" function
that acts kind of like gmtime_r(), but using the 64-bit timestamp_t. It
matches our original "utc_mktime()".

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.

When first trying to deal with this I opted to go with a two pass appoach
which seemed easy as it used existing infrastructure, but turned out to
run into a couple of odd corner cases that would have been really ugly to
deal with.
So I threw this code away and am instead doing this in a single pass,
carefully checking as we go if there is an appropriate trip we can use.
To me the new code is much easier to read and seems much cleaner.

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.

There are a few obvious trip manipulations on multiple dives that haven't
been implemented, yet. This commit handles the case when we have multiple
dives selected and right click on one of them. It now removes all of those
dives from their trips (instead of just the one that we clicked on).
Still todo is the inverse operation. Select a group of consecutive dives
and turn them into a trip.

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...

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.

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.

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.

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).

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
