1593f2ebad Import: merge dives trip-wise
The old way of merging log-files was not well defined: Trips
were recognized as the same if and only if the first dives
started at the same instant. Later dives did not matter.

Change this to merge dives if they are overlapping.
Moreover, on parsing and download generate trips in a separate
trip-table.

This will be fundamental for undo of dive-import: Firstly, we
don't want to mix trips of imported and not-yet imported dives.
Secondly, by merging trip-wise, we can autogroup the dives
in the import-data to trips and merge these at once. This will
simplify the code to decide to which trip dives should be
autogrouped.

In 302f6adb79 dive-splitting was made
undo-able. To this goal, the dive-splitting functions were split in
two types: Those that operate directly on the divelist and those that
only allocate the dives. The former are not in use anymore, therefore
remove them. Since only the latter remain, remove the "_dont_insert"

3cdc2661d2 Dive media: add media to closest dive
Currently, when selecting "Load media files even if time does not
match the dive time", the media are added to *all* selected dives.
Instead add it to the closest dive.

This seems like the less surprising behavior. Of course now if the
user really wants to add a media file to multiple dives, they will
have to do it manually.

To avoid a messy interface, this is solved by moving the iterate-
over-selected-dives loop to the core. Thus, a helper-function can
be made local to its translation unit.

6bf4120dbb Core: replace tripflag by notrip boolean
The only remaining use of the tripflag was to mark dives that
were removed explicitly from a trip, i.e. shouldn't be autogrouped.
Therefore replace the enum by a simple boolean.

3b9e0b5931 Core: remove ASSIGNED_TRIP trip flag
The distinction between ASSIGNED_TRIP and IN_TRIP was used to
prefer non-autogenerated trips on merging of dives. But owing
to bit rot this seem to have worked only partially anyway:
The IN_TRIP field was set in create_and_hookup_trip_from_dive()
and immediately overwritten in add_dive_to_trip() called
in the next line.

Instead, use the trip->autogen flag to check for priority and

Dive importing is now performed via a distinct table which is

21b1550739 Dive media: on import read metadata only once
On import of dive media, the timestamp is read from the
metadata to check if the image belongs to the selected dives.
The pictures are then listed in a dialog.

Currently, the metadata is read twice if images are outside
of a dive: once in picture_check_valid() and if it turns
out that the picture is not valid again in picture_get_time()
to display the proper timestamp.

Even though metadata-extraction is reasonably fast, this is
a bit of an embarrassment.

Instead, read the timestamps only once in the constructor of
the dialog and from then on only used these timestamps. Keep
the timestamps in a QVector. Rename the picture_check_valid()
function to picture_check_valid_time() and pass a timestamp
instead of a filename.

92deb7aa70 Cleanup: make surface sample in merge_one_sample() non-static
The merge_one_sample() function adds a sample to the destination
dive if dives are merged. For long periods between samples at surface
depths, it adds a surface interval.

To decrease the number of global objects, make the sample structure

slower. Therefore move it into the corresponding if. Thus, the

6e4a253896 Profile: fix SAC calculation for air dives
Commit f5b11daffd changed gasmix
arguments and return values to be passed by value instead of
using pointers.

Notably, get_gasmix() is fed a default-value and returns a
new value. In the old code, NULL was passed in in a first
loop iteration and non-NULL was always returned in the first
iteration. Thus, an equality comparison of passed-in an
returned gasmix would always fail in the first loop iteration.

The new code passed in air as default. Now if air was also
returned, then the matching gases were not calculated in
calculate_sac(). To revert to the old behavior, pass in
an invalid gasmix.

Moreover, give names to the invalid and air gasmixes.

360f07e453 Cleanup: pass gasmix by value
In a previous commit, the get_gasmix_* functions were changed to
return by value. For consistency, also pass gasmix by value.

Note that on common 64-bit platforms struct gasmix is the size
of a pointer [2 * 32 bit vs. 64 bit] and therefore uses the
same space on the stack. On 32-bit platforms, the stack use
is probably doubled, but in return a dereference is avoided.

Supporting arbitrary gas-mixes (H2, Ar, ...) will be such an
invasive change that going back to pointers is probably the
least of our worries.

This commit is a step in const-ifying input parameters (passing
by value is the ultimate way of signaling that the input parameter
will not be changed [unless there are references to said parameter]).

f5b11daffd Cleanup: return gasmix by value
Currently, get_gasmix_from_event() and get_gasmix() return pointers
to either static or to (possibly changing) dive data. This seems like
a dangerous practice and the returned data should be used immediately.

Instead, return the gasmix by value. This is in preparation of
const-ifying input parameters of a number of core functions, which
will ultimately let the merge() function take const-arguments in
preparation of undo of dive-merging.

On common 64-bit systems gasmix (two "int"s) is the size of a pointer
and can be returned in a register.

On 32-bit systems a pointer to the struct to be filled out will be
passed.

Since get_gasmix() now returns a value, the first invocation is
tested by a NULL-initialized "struct event *". Document this in
a comment.

2c6b1a99af Cleanup: simplify dive_getUniqID()
dive_getUniqID() is used to create unique dive ids, which are
stable during application lifetime. It was passed a dive, checked
that the id was not set (if it was that it is know to the application)
and set a new id (in contradiction to its name!) if it hadn't any.

There were three callers:

alloc_dive(): called the function on a zeroed dive struct.
fixup_dive(): called the function only if the dive had a 0 id.
MainWindow::setupForAddAndPlan(): called the function on a zeroed dive
struct.

Thus, in all three callers the id is guaranteed to be zero and
the whole keeping-track-of-ids logic is moot. Remove the logic,
don't pass a dive struct to dive_getUniqID() and move the function
to the C-backend.

3209b490dd Use proper sample pointer when deciding to split dives
The dive splitting was completely wrong, because we checked the time of
the previous sample by doing

	sample[i - 1].time.seconds

which is entirely wrong.  The 'sample' variable is the *current* sample,
so the time of the previous sample is simply

	sample[-1].time.seconds

Alternatively, we could have started from the first sample, and done

	dc->sample[i - 1].time.seconds

but mixing the two concepts up just gets you a random sample pointer
that is likely not a valid sample at all, and obviously does not have
the right time at all.

As a result, dive splitting was pretty much random.  Sometimes it worked
purely by mistake, because the rest of the logic was right (ie we _had_
found the right point where we reached the surface in the dive etc, the
"previous sample time" was simply used to decide if the surface interval
was sufficient to split the dive up).

2e8f506635 Dive pictures: remove cache_picture() call in dive_add_picture()
When adding a picture to a dive, cache_picture() was called, which
calculated the hash of the picture in a background-thread.

This made tests occasionally fail, because the tests depended on
the filename-to-localfilename being overwritten in a call running
in a different thread. Depending on which thread finished first,
the test succeeded or failed.

The easiest way to circumvent this problem is to remove the cache_picture()
call. The hash will be calculated anyway with the thumbnails. And
the only function of the hash is the "find moved images" function. Which
is not an issue here, because the user just loaded the images from
disk.

780530f32e Bugfix: Load PSC dive logs
The code changes to standardise the named of divemodes and to
separate internal divemode names and UI divemode names introduced
a bug that caused non-backward compatability with existing
dive logs. The reason for this is the definition of the
divemode_text strings in dive.c

This change reverses that definition and brings about correct
loading of PSCR dive logs as well as correct parsing of bailout
events involving PSCR.

27a0542220 Implement bailout outside of the dive planner
This is the second step for implementing bailout. The indirect
calls to fill_pressures through add_segment() (in deco.c) are
addressed. Bailout is now fully implemented in the dive log but
not in the dive planner.
1) The parameters to add_segment() are changed to take a
   divemode as the second last parameter, and not a *dive.
2) Call to add_segment() in profile.c and in divelist.c are
   adapted. In divelist.c some calls to add_segment were left
   using dc-> divemode instead of possible bailout. This appears
   tp be the most appropriate route.
3) The functions get_divemode_from_time() and get_next_divemodechange()
   in dive.c have had some small changes.
4) The calls to get_segment(0 in planner.c were changed to reflect
   the new parameter list, but not updated to reflect bailout. This
   is the next step.

cf377beb2e Incorporate bailout events in CCR & PSCR gas calculations.
This is a first step to interpret bailout events.
1) The event structures have a new attribute: divemode.
   Currently interpreted dive modes are OC, CCR, PSCR.
2) When doing fill_pressures(), the calculation is aware
   of divemode. When divemode is OC (==bailout), then
   the appropriate calculations of gas pressures are done.
3) Two new functions get_next_divemodechange() and
   get_divemode_at_time() are created to find divemode
   changes in the events linked list and to determine
   the dive mode at any point during the dive.
4) fill_pressures gets a small amendment to facilitate
   the correct calculations, depending on divemode.
The cases where fill_pressures() is used *outside the planner*
are changed. The result is that, for dives with bailout, the
correct gas pressures are shown on the dive profile. The
deco for bailout dives is not yet correct. This is the
next step.

920ff15f71 Planner: don't return static data in fake_dc()
fake_dc() used to return a statically allocated dc with statically
allocated samples. This is of course a questionable practice in
the light of multi-threading / resource ownership. Once these
problems were recognized, the parameter "alloc" was added. If set
to true, the function would still return a statically allocated
dc, but heap-allocated samples, which could then be copied in
a different dc.

All in all an ownership nightmare and a recipie for disaster.
The returned static dc was only used as a pointer to the samples
anyway. There are four callers of fake_dc() and they all have access
to a dc-structure without samples. Therefore, change the semantics
of fake_dc() to fill out the passed in dc. If the caller does
not care about the samples, it can simply reset the sample number
to zero after work.

bdc470a80e Cleanup: Remove hash field from picture-structure
The hash field in the picture-structure was in principle non-operational.
It was set on loading, but never actually changed. The authoritative

Therefore, make this explicit by removing the hash field from the
picture structure.

Instead of filling the picture structure on loading, add the
hash directly to the filename->hash map. This is done in the
register_hash() function, which does not overwrite old entries.
I.e. the local hash has priority over the save-file. This
policy might be refined in the future.

sense because if one marks a cylinder explicitly as "unused" in the
