b50d5b63ad Preserve events when editing dive in planner
The planner does not know about events except gas
changes. But if the dive comes from the log, we
should preserve the dive computer events. At least
those that happend before we started to delete
waypoints to let the planner take over.

ab8e317b28 undo: implement renaming of events
There is a slight complexity here owing to the fact that the profile
works on a copy of the current dive: We get a copy of the event and
have to search for the original event in the current dive. This
could be done in the undo command. Nevertheless, here we do it in
the profile so that when in the future the profile can work on a
non-copied dive we can simply remove this function.

3aa1bb5bfa core: add remove_event_from_dc() function
We have a remove_event() function that
1) frees the event
2) works on the current divecomputer
3) compares the events because the profile has copies of events

However, for undo commands
1) we want to keep the event so that we can readd it later
2) we have to work on arbitrary divecomputers
3) we don't work with copies of events

Therefore, create a new remove_event_from_dc() function that
does all that. Moreover, make the event argument to remove_event()
const to (slightly) point out the difference in the API.

6434ad2628 filter: add fulltext filtering code
Add code that indexes all words of a dive and provides searching
for words.

A query is represented by the FullTextQuery class, which can be
initialized by assigning a string to it. It is basically a list
of words.

The result of a search is stored in the FullTextResult class,
which is a list of dives.

The actual indexing and searching is implemented in the FullText
class. However, this class is not exported because the interface
is partially accessible to C. Notably, the reloading of the
fulltext index is done from the C core.

Currently, the indexing and searching is totally unoptimized.
In a ~4000 dives test-log searches typically took single-digit
ms times. There is ample room for optimization (e.g. when
searching for multiple words, chose the words with few dives
first and when down to a few dives, check them individually).

The words of each dive are tokenized and uppercased and
cached with the dive. A pointer to these words is stashed
in the dive structure.

For now, compile only on desktop.

7c9f46acd2 Core: remove MAX_CYLINDERS restriction
Instead of using fixed size arrays, use a new cylinder_table structure.
The code copies the weightsystem code, but is significantly more complex
because cylinders are such an integral part of the core.

Two functions to access the cylinders were added:
get_cylinder() and get_or_create_cylinder()
The former does a simple array access and supposes that the cylinder
exists. The latter is used by the parser(s) and if a cylinder with
the given id does not exist, cylinders up to that id are generated.

One point will make C programmers cringe: the cylinder structure is
passed by value. This is due to the way the table-macros work. A
refactoring of the table macros is planned. It has to be noted that
the size of a cylinder_t is 64 bytes, i.e. 8 long words on a 64-bit
architecture, so passing on the stack is probably not even significantly
slower than passing as reference.

00944f7a02 Core: pass dive, cylinder-id to fill_default_cylinder
The fill_default_cylinder() function calculated the MOD based
on the currently displayed dive. This does not seem to make sense:
- When importing dives, why would we care about the altitude and
  salinity of the currently displayed dive, possibly from a different
  trip.
- The planner is supposed to be thread-safe and should not touch
  global variables.

Of course this means that the importing-functions have to fill
out altitude and salinity before creating the default cylinder,
but this is their problem. For a freshly created dive they will
get the default values, which still seems less random than the
values from the displayed dive.

c685c05ff4 Fix cylinder gas type saving when we have bogus gas use data

It turns out that if we can't parse the cylinder use type (OC, diluent,
oxygen, unused) we initialize the cylinder use to an invalid type, and
then when we save it, we mess up.

Fix it up by doing proper limit checking before accessing the
"cylinderuse_text[]" array when saving.

Some dive computers save GPS data. Currently, this is stored
by libdivecomputer in an "extra field". When generating a
new dive site for a dive try to use this data to place the
dive site.

To do so, create a "dive_get_gps_location()" function. This
function can be extended later to use e.g. event. When creating
a dive site, use the result of this function over a potential
pre-existing dive site.

145f70aab5 Undo: implement split-out of dive computer
Allow splitting out a dive computer into a distinct dive. This
is realized by generating a base class from SplitDive.

This turned out to be more cumbersome than expected: we don't
know a-priori which of the split dives will come first. Since
the undo-command saves the indices where the dives will be insert,
these have to be calculated. This is an premature optimization,
which makes more pain than necessary. Let's remove it and
simply determine the insertion index when executing the command.

bfe69239df Import: unglobalize downloadTable
To make data flow more clear, unglobalize the downloadTable object.
Make it a subobject of DownloadThread. The difficult part was making
this compatible with QML, because somehow the pointer to the

simply pass it to the constructor. But with objects generated in QML
this is not possible. Instead, pass the table in the repopulate()
function. This seems to make sense, but for this to work, we have to
declare pointer-to-dive-table as a Q_METATYPE. And this only works
if we use a typedef, because MOC removes the "struct" from "struct
dive_table". This leads to compilation errors, because dive_table is
the symbol-name of the global dive table! Sigh.

0618aa737f Core: unify insert_trip() and insert_trip_dont_merge()
There were two versions of the insert_trip() function: one
would merge trips if a trip with the same date already existed,
the other wouldn't. The latter was introduced with the dive-list
undo work.

The problem is that the "date" of a trip (i.e. the first dive)
seems ill-defined as this is a volatile value. Moreover in
the context of making dive-import undoable this is a very
dangerous notion, as the caller needs control over when the dives
are added to a trip.

Therefore, unify these two functions and never merge trips.
The decision on merging dives now has to made by the caller.
This will be implemented in a future commit.

7067e33596 Undo: select dives after add, remove, merge, split dive commands
Select the proper dives after the add, remove, split and merge
dives commands on undo *and* redo. Generally, select the added
dives. For undo of add, remember the pre-addition selection.
For redo of remove, select the closest dive to the first removed
dive.

The biggest part of the commit is the signal-interface between
the dive commands and the dive-list model and dive-list view.
This is done in two steps:
1) To the DiveTripModel in batches of trips. The dive trip model
   transforms the dives into indices.
2) To the DiveListView. The DiveListView has to translate the
   DiveTripModel indexes to actual indexes via its QSortFilterProxy-
   model.

For code-reuse, derive all divelist-changing commands from a new base-class,
which has a flag that describes whether the divelist changed. The helper
functions which add and remove dives are made members of the base class and
set the flag is a selected dive is added or removed.

To properly detect when the current dive was deleted it
became necessary to turn the current dive from an index
to a pointer, because indices are not stable.

Unfortunately, in some cases an index was expected and these
places now have to transform the dive into an index. These
should be converted in due course.

6ac4ddbeed Core: introduce insert_trip_dont_merge() function
insert_trip() adds a trip to the backend, but merges trips if
there exists a trip with the same date. This is a disaster
for the MergeTrips command, because this command adds a new
trip and removes the previous two. Of course if the added trip
is merged, this cannot work.

Therefore, add an insert_trip_dont_merge() function, which
adds the trip, but doesn't merge.

014c04f8bd Undo: implement rudimentary support for undo of dive-merging
For this, an output-parameter was added to the backend merge_dives()
function. When non-zero, instead of adding the merged dive to
the preferred trip, the preferred trip is returned to the caller.

Since the new UndoObject, just like the delete-dives UndoObject,
needs to remove/readd a set of dives, the corresponding functionality
was split-off in a helper function.

302f6adb79 Undo: implement rudimentary support for undo of dive-splitting
For this, the core functionality of the split_dive() and
split_dive_at_time() functions were split out into new
split_dive_dont_insert() and split_dive_at_time_dont_insert(),
which do not add the new dives to the log. Thus, the undo-command
can take ownership of these dives, without having to remove them
first.

The split-dive functionality is temporarily made desktop-only
until mobile also supports "UndoObjects".

Play manual addition of dives via an UndoCommand. Since this does in
large parts the same thing as undo/redo of dive deletion (just the

403dd5a891 Undo: fix multi-level undo of delete-dive and remove-dive-from-trip
The original undo-code was fundamentally broken. Not only did it leak
resources (copied trips were never freed), it also kept references
to trips or dives that could be changed by other commands. Thus,
anything more than a single undo could lead to crashes.

Two ways of fixing this were considered
1) Don't store pointers, but unique dive-ids and trip-ids.
   Whereas such unique ids exist for dives, they would have to be
   implemented for trips.
2) Don't free objects in the backend.
   Instead, take ownership of deleted objects in the undo-object.
   Thus, all references in previous undo-objects are guaranteed to
   still exist (unless the objects are deleted elsewhere).

After some contemplation, the second method was chosen, because
it is significantly less intrusive. While touching the undo-objects,
clearly separate backend from ui-code, such that they can ultimately
be reused for mobile.

Note that if other parts of the code delete dives, crashes can still
be provoked. Notable examples are split/merge dives. These will have
to be fixed later. Nevertheless, the new code is a significant
improvement over the old state.

While touching the code, implement proper translation string based
on Qt's plural-feature (using %n).

d3d06bc580 Cleanup: split out free_dive() function from delete_single_dive()
Currently, we can only delete dives that are indexed in the main
dive table. In the future, we will have to delete dives outside
of this table (e.g. for undo). Therefore, split out the free_dive()
function from delete_single_dive(), which takes an index into
the main dive table.

In the process, adopt the dive freeing-code from clear_dive(),
which frees more data than the code in delete_single_dive().
This potentially fixes a memory-leak.

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.

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.

This concerns functions taking pointers to events and
the fallout from making these const.

The somewhat debatable part of this commit might be
that get_next_event() is split in a two distinct
(const and non-const) versions with different names,
since C doesn't allow overloading. The linker should
recognize that these functions are identical and remove

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.
