Use owning pointers in GraphicsWinQt to own the GLwindow and QOGLContext,
so shutdown is more orderly, especially when driven from the OSG or
window-manager, as opposed to an ‘internal’ quit.
In order to compute the AI aircrafts wake, the FDM will need access to the list of AI aircrafts as well as being able to compute their range to discard aircrafts which are too far.
In the thread at
<https://sourceforge.net/p/flightgear/mailman/flightgear-devel/thread/87tw7sm5uw.fsf%40frougon.crabdance.com/#msg35673402>,
it was decided that alignLocaliserWithRunway() was a bad idea overall,
and should just be removed. The feature was already disabled by default
in recent releases via defaults.xml (since FlightGear 2017.1, precisely
FGData commit ea76305e42fd245e79a2b5bb569c8c61161f5721). Remove the code
entirely now.
The properties /sim/navdb/localizers/auto-align and
/sim/navdb/localizers/auto-align-threshold-deg have no effect anymore,
you may remove them from your configs if you somehow set them.
This goes with FGData commit 6dd9f6e8d962b00a1ccddc6af487c404cc935b92.
In case someone wanted to reuse the removed code, please consider
Szymon's proposed change at
<https://sourceforge.net/p/flightgear/flightgear/merge-requests/76/>,
which was:
,----
| Fixed bug in alignLocaliserWithRunway when building NavCacheDb
|
| The position of the localizer was converted to a distance from
| the displaced threshold, and then back to the posistion on the
| centerline, but the origin of the second computation was
| non-displaced threshold.

There was a couple of typos in the routine. This code will be used by the AI wake feature.
Also added a test for the matrix code to make sure they will be no regression.
External moments can now be specified in addition to external forces. This feature is needed for the AI wakes.
Headers clean up to reduce the amount of recompilation when modifying an header file.
Print an error message and exit if --{enable,disable}-enhanced-lighting
or --adf are used (those deprecated options will be removed in a future
version of FlightGear).
Add man pages for those programs that did not have one (exceptions:
yasim and yasim-proptest) and update the existing ones to make them
compliant with man-pages(7) conventions.
As spotted by Thorsten, reduce user annoyance by asking about FGData
when the built-in data is acceptable. (Advanced users can use the
launcher or other options to change FGdata as normal).
* Skip the gears when located over water. They will be skipped by the ground reactions anyway making the trim irrelevant.
* Ignore the ground bumpiness during the trim. The trim algorithm seems not to
be robust enough to handle that. This does not make much difference to the
converged solution anyway since the bumpiness is generally low.
* Fixed the WOW status for contacts over water (was 'false' is now 'true').
* All the gear/contact data are now properly reset when WOW==false. The reset
code is now common to all the case where WOW is false.
When the user specified an MP server without providing a port, the
launcher would pass a malformed command line, leading the the simulator
bailing out.
(Should go to the release branch)
Add defensive logic to ensure that a null pointer isn't dereferenced. This happened to me once or twice during a reinit (Location/Position In Air to the current position). It may be related to the model, but in any case the code needs to ensure that the static cast failure is handled correctly.
2017.2 in compatible mode was not compatible with 2017.1.x because the V1 packet had V2 properties in it; the protocol version and the new launchbar encoding - both of which should not be transmitted. This only affected 2017.1 because it discards the rest of the packet once an unknown property is encountered (to increase reliability).
Remove obsolete *NIX packaging files (they have not been updated in a long
time, and packaging is handled by each Linux distribution), plus an old,
generic FlightGear icon used exclusively by the Debian package and not
matching the official logo.
Thanks to Chris Blues, Thorsten Renk, Alessandro Menti,
Andrius Štikonas, Erik Hofman, Chimpa Theist, Emilian Huminiuc
and 梁思地 (Sidi Liang) for their translation work (sorted by
locale name!).
Add support for per property encoding.
- encode_for_transmit - method that will convert from and to the packet for the value.
- decode_received - decodes received data
Just for consistency and cleanliness, following commit
4b48aca411. The 'package/debian' directory
is going to be removed soon, anyway[1].
The 'RedHat' and 'openSUSE' directories in 'package' don't need such a
change, because they use their own desktop file (and they should also be
removed after the 2017.2.1 release).

The options.cxx code is not ready to handle recursive use of --config
(for config files). Instead of failing in an ugly way, abort with a
clear error message in such situations. See discussion at
<https://sourceforge.net/p/flightgear/mailman/message/35838852/>.
Note: it *is* possible to load XML PropertyList files from config files,
so --config is not entirely "banned" from config files.
+ add missing include
New Nasal method get_cart_ground_intersection
Returns where the given position in the specified direction will intersect with the ground. Returns whether or not a certain position and direction pair intersect with the ground, and if so the intersection point.
Useful for radars, terrain avoidance (GPWS), etc.
Input parameters:
1. vec3d(x,y,z) position
2. vec3d(x,y,z) direction
Returns nil or geod hash (lat:rad,lon:rad,elevation:Meters) intersection
Example Usage:
var end = geo.Coord.new(start);
end.apply_course_distance(heading, speed_horz_fps*FT2M);
end.set_alt(end.alt() - speed_down_fps*FT2M);
var dir_x = end.x() - start.x();
var dir_y = end.y() - start.y();
var dir_z = end.z() - start.z();
var xyz = { "x":start.x(), "y" : start.y(), "z" : start.z() };
var dir = { "x":dir_x, "y" : dir_y, "z" : dir_z };
var geod = get_cart_ground_intersection(xyz, dir);
if (geod != nil) {
end.set_latlon(geod.lat, geod.lon, geod.elevation);
var dist = start.direct_distance_to(end)*M2FT;
var time = dist / speed_fps;
setprop("/sim/model/radar/time-until-impact", time);
}
-----------
Nasal method aircraftToCart : This allows easily computing offsets in aircraft-relative coordinates, and converting to global cartesian (ECEF) reference frame.
This has the advantage, according to my testing on Linux, that core
files obtained after a crash now point to the crashing thread again,
when one starts 'gdb' on the core file and runs the 'bt' command.
Apparently, when using kill(), the signal is seen as coming from the
outside and gdb's 'bt' command points to the wrong thread in general
when debugging using a core file (when debugging "live", gdb intercepts
the signal even before FG's signal handler is started).
