2ba3eab319 Bluetooth: discovery should always scan on macOS as well
Instead of only starting the scan when explicitly asked to do so in the BT
dialog, create the discovery agent when the download dialog opens, since on
macOS we cannot connect to a device without having scanned for it first.

ad57871a2c Geo lookup: don't pass arguments / result via global object
The reverseGeoLookup() fetches dive-site data via GPS coordinates.
The coordinates and the result were passed via the global

04ad9c885d Geo lookup: make the reply a managed-pointer
By making reply a std::unique_ptr<>, the function can be quit
from any point and the reply will be freed. This is valid according
to Qt's documentation as we're not deleting during signal processing.

This commit fixes a leak: reply was overwritten with the address of
a new object without freeing the old object.

cb2f09a8e3 Geo lookup: make the QNetworkAccessManager a static object
According to Qt's docs, the QNetworkAccessManager is supposed
to be a long-living object. Therefore, don't create one on
every geo-lookup, but a single object for all geo-lookups.

By making the object function-local it is only initiaized
on first use. Morover this limits the amount of concurrent
geo lookups.

ce8199cdfd Cleanup: remove ReverseGeoLookupThread
Fetching the taxonomy from GPS coordinates was implemented in
a QThread. But the only access to the main function was a
direct call to run(). Thus, the thread was *never* started.
The function call was always asynchronous [it was using an
event loop though, so the UI doesn't hang]. Notably this
means that the signals connected to the thread would never
fire. And the spinner would never be activated.

Thus:
1) Turn the thread into a simple function.
2) Remove the spinner.

8c2383b495 Undo: don't modify source-dives on merge
For undo, it is crucial that commands don't modify existing dives.
Unfortunately, dive merging would write into the data-structures
of the to-be-merged dives. To prevent it from doing so, make the
input dives const-pointers.

This led to a whole cascade of functions that had to take const
and significant churn.

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.

23db0ba68d Dive list view: replace signal-magic by flag
In DiveListView, we have a very fundamental problem: When
On the one hand, we get informed of user-selection in the
DiveListView::selectionChanged() slot. This has to set the
correct flags in the C-backend.

On the other hand, sometimes we have to set the selection
programatically, e.g. when selecting a trip. This is done
by calling QItemSelectionModel::select().

But: this will *also* call into the above slot, in which
we can't tell whether it was a user interaction or an
internal call. This can lead to either infinite loops or
very inefficient behavior, because the current dive
is set numerous times.

The current code is aware of that and disconnects the
corresponding signal. This is scary, as these signals are
set internally by the model and view. Replace this
by a global "command executing" flag in DiveListNotifier.
The flag is set using a "marker" class, which resets the flag
once it goes out of scope (cf. RAII pattern).

In DiveListView, only process a selection if the flag is not
set. Otherwise simply call the QTreeView base class, to reflect
the new selection in the UI.

To have a common point for notifications of selection changes,
add such a signal to DiveListNotifier. This signal will be
used by the DiveListView as well as the Command-objects.

ec7d85835f Dive list: implement proper Qt-model semantics for DiveTripModel
Previously, each dive-list modifying function would lead to a
full model reset. Instead, implement proper Qt-model semantics
using beginInsertRows()/endInsertRows(), beginRemoveRows()/
endRemoveRows(), dataChange().

To do so, a DiveListNotifer singleton is generatated, which
broadcasts all changes to the dive-list. Signals are sent by
the commands and received by the DiveTripModel. Signals are
batched by dive-trip. This seems to be an adequate compromise
for the two kinds of list-views (tree and list). In the common
usecase mostly dives of a single trip are affected.

Thus, batching of dives is performed in two positions:
- At command-level to batch by trip
- In DiveTripModel to feed batches of contiguous elements
  to Qt's begin*/end*-functions.

This is conceptually simple, but rather complex code. To avoid
repetition of complex loops, the batching is implemented in
templated-functions, which are passed lambda-functions, which
are called for each batch.

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.

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).

d2d9821170 Fix warning about unused variables
Commit 810903bdb9 ("Import: pass a dive table to process_imported_dives()")
introduced the variables

        struct dive *old_dive, *merged;

into process_imported_dives(), but never used them.  It seems to be an
artifact of having split the function to use the try_to_merge_into()
helper function (that has those same variable names and _does_ use
them), but forgetting the original variables from the pre-split case.

Gcc understandably warns about it:

  core/divelist.c: In function ‘process_imported_dives’:
  core/divelist.c:1351:26: warning: unused variable ‘merged’ [-Wunused-variable]
    struct dive *old_dive, *merged;

7618240009 ftdi: make the timeout be based on actual real time
bperrybap reported on github that the ftdi timeouts can be excessive:

  "the timeout period while waiting for read data to be 10x or even 100x
   longer than it should be when there are read issues on the data cable
   particularly when using Android and USB OTG cables. i.e. a 5 second
   read timeout for not receiving data can be as long as 7 minutes"

and the reason is that the code at one point tried to use the regular
"gettimeofday()" to handle timeouts, but that doesn't exist in Windows.

We already have Windows-specific code to sleep for a number of
milliseconds in "ftdi_serial_sleep()", let's just extend that same
concept and add a "ftdi_serial_get_msec()" that returns the number of
msec's since some arbitrary point in time.

On Windows, that's just "GetTickCount()", and in sane environments it's
just a trivial wrapper around gettimeofday() to turn sec/usec into msec.

NOTE! The actual msec value doesn't have any meaning.  Only the
difference between two calls to ftdi_serial_get_msec() is meaningful.

Dives were directly imported into the global dive table and then

by passing an independent dive table.

The dive table of the to-be-imported dives will be sorted and merged.
Then each dive is inserted in a one-by-one manner to into the global

This actually introduces (at least) two functional changes:
1) If a new dive spans two old dives, it will only be merged to the
   first dive. But this seems like a pathological case, which is of
   dubious value anyway.
2) Dives unrelated to the import will not be merged. The old code
   would happily merge dives that were not even close to the
   newly imported dives. A surprising behavior.

cd55344410 qt-ble: add support for libdivecomputer 'set_timeout()' function
Because some BLE operations can be very slow (device and service
discovery etc), we have some rather excessive default timeout for BLE
(currently set to 12 seconds).

But once we actually have started doing IO, that long timeout can be a
big performance problem, when the libdivecomputer backend has support
for retry and packet loss.

For that reason, libdivecomputer has a 'set_timeout()' function that
allows the divecomputer backend to say how quickly it expects the dive
computer to answer before the backend will start resending packets.

Let's just implement that for the actual IO side of BLE too.  The
default timeout value remains the general BLE timeout, and this only
affects the actual IO phase, but it improves things enormously for the
case where there is packet loss at that point.

For example, on the Aqualung i770R, the timeout for packet loss ends up
now being just one second rather than the full 12 seconds of default BLE
timeout.  Which gets the retry going much faster.

ec532b8f59 qt-ble: move basic uuid filtering back to service discovery
In commit 30fb7bf35c ("qt-ble: set up infrastructure for better
preferred service choice") I moved the service filtering from the
addService() callback into the "select_preferred_service()" function
that picks the right service for the device.

That was nice for debugging, since it meant that we showed the details
of _all_ services, but it also meant that we ended up starting service
discovery on _all_ services, whether they looked at all interesting or
not.

And that can make the BLE device discovery process quite a bit slower.

The debugging advantage is real, but honestly, service discovery can
generally be better done with specialized tools like the Nordic nRF app,
so the debugging advantage of just listing all the details of all the
services is not really worth the discovery slowdown in general.

So move the basic "filter by uuid" back to the service discovery phase,

ebee0c4c24 Fix error handling for libdivecomputer import
The error handling was incorrect for the case where we successfully
opened the libdivecomputer iostream in divecomputer_device_open(), but
the dc_device_open() call failed.

When the dc_device_open() failed, we would (correctly) not do the
dc_device_close() but we would _also_ not do the dc_iostream_close() to
close the underlying file descriptor, which is wrong.

Normally this isn't all that noticeable, partly because the common case
is that dc_device_open() succeeds if you actually do have a dive
computer connected, but also because most of the time it just leaked a
file descriptor or something like that.

However, particularly for the POSIX serial device case, libdivecomputer
does a

	ioctl(device->fd, TIOCEXCL, NULL)

call to make serial opens exclusive.  This is what we want - but if we
then fail at closing the serial file descriptor, we won't be able to
retry the import at all because now the next open will fail with EBUSY.

So the error handling was incorrect, and while it doesn't usually matter
all that much, it can be quite noticeable particularly when you have
transient errors.

420aab9454 Cleanup: don't produce no-dives error message in libdivecomputer.c
If no dives were downloaded in do_libdivecomputer_import(), an
error message would be produced. To check for downloaded dives,
the function would access the global downloadTable instead of
the actual table the dives are imported to (at the moment the
same - but the interface allows for a different table).

Move the error-creation to the caller to avoid this situation.
An alternative option would be to check the actual table the
dives were supposed to be downloaded to. But from a program-logic
point of view "no dives" does not seem like an error condition.

8a18396104 Cleanup: don't access downloadTable directly in Uemis-downloader

The downloadTable is passed in the device data structure, but
in the function to determine the latest dive, the global
downloadTable is accessed directly [thus supposing that this

Instead, use the table from device data to avoid funny surprises
should we change to a non-global download table.

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

In the process, adopt the dive freeing-code from clear_dive(),
which frees more data than the code in delete_single_dive().

890d4c3d64 qt-ble: allow reading of partial packet data
The existing BLE dive computers treat BLE as the packetized protocol it
is, and read whole packets at a time.

However, the Mares BlueLink backend treats it as just a basic "serial
over BLE" transport, and for historical reasons reads the reply packets
in smaller chunks.

This allows that kind of IO behavior, where if the divecomputer backend
reads just a part of a packet, we'll split the packet, return the part
the user asked for, and push back the leftover packet onto the received
packet queue.

cc4f48be3f Metadata: rudimentary support for XMP metadataa in MP4-based videos
XMP is a media-metadata standard based on XML which may be used
across a variety of media formats. Some video-processing software
writes XMP data without updating the native metadata fields.
Therefore, we should aim at reading XMP metadata and give priority
of XMP data over native fields.

Pros:
	- Support for *all* common media formats.
Cons:
	- XML (complex, verbose, chaotic).
	- Does not even come close to fulfilling its promise of being
	  well defined (see below).

Implement a simple XMP-parser using libxml2. Connect the XMP-parser to
the existing Quicktime/MP4 parser.

First problem encountered: According to the spec, XMP data supposed
to be put in the 'XMP_' atom. But for example exiftools instead
writes an 'uuid' atom with a special 16-byte uid. Implement both,
more options will probably follow.

Second problem: two versions of recording the creation date were found
  1) The content of a <exif:DateTimeOriginal> tag.
  2) The xmp::CreateDate attribute of a <rdf:Description> tag.

Here too, more versions are expected to surface and will have
to be supported in due course (with an obvious priority problem).

that supported both.

However, this first/last hack definitely doesn't work for the Mares
BlueLink BLE dongle, and it's really all pretty wrong anyway.

So re-organize the code to actually look at the properties of the
characteristics.  I don't have a BlueLink to test with, but my EON Core
and Shearwater Perdix AI are still happy with this, and the code
conceptually makes a lot more sense.

30fb7bf35c qt-ble: set up infrastructure for better preferred service choice
We used to just pick the first non-standard service we found (with a
special case for the Heinrichs Weikamp dive computers that have an
actual registered standard service).

We then waited for that service to finish discovery, and started using
it.

This changes the logic to wait for _all_ services to finish discovery,
and then after that we pick the one we like best.  Right now the rule
for picking a preferred service is the same one we had before, but the
difference is that we now have the full discovery data, so we *could* do
something better.

Plus this makes our debug messages a lot more legible, when we don't
have the mix of overlapping service discovery with the actual IO we do
to the preferred service.

NOTE! This doesn't much matter for most of the dive computers that we
currently support BLE for.  They don't tend to have a lot of odd
services.

But at least both the Mares BlueLink and the Garmin Descent both have
multiple services and it's not obvious which one to use, and this will
make it not only easier to debug those, it will make it easier to pick
the right preferred service descriptor to use.

process_dives() is used to post-process the dive table after loading

load or import.

Especially in the light of undo, load and import are fundamentally
different things. Notably, that latter should be undo-able, whereas
the former is not. Therefore, as a first step to make import undo-able,
split the function in two versions and remove the first parameter.

It turns out the the load-version is very light. It only sets the
DC nicknames and sorts the dive-table. There seems to be no reason
to merge dives.

d2b8088cd8 Actually create a UUID when creating a dive site during download
The existing code creates a deterministic ID (not exactly "unique") in order to
help us avoid merge conflicts in git-storage mode. But as a side effect, if we
re-download the same dive twice from a dive computer that supports GPS (right
now only the Garmin Descent Mk1) we are guaranteed to create the same dive site
uuid when we do this. So when we download a dive - whether we will actually
*use* that dive later or not - we will be filling in the dive site information
with the data we got from the dive computer.

... and in the process we will be overwriting any data that was filled in
manually. The name of the dive site, but also possibly even the GPS of the dive
site (maybe the user decided to edit that using the map, because while the
automatically downloaded GPS data was "correct", maybe the user wanted to
change it to be the actual under-water location using the satellite data,
rather than the place where you started the dive or where you surfaced).

In order to avoid this collision, this patch just makes the libdivecomputer
download not use the dive time, but "time of download" for the dive site time,
and thus effectively generate a new uuid for every download.

On import of dive media, the timestamp is read from the

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.
