Gives the ability to define graphics settings via an XML file at
startup or later during runtime. Tracks if changes to graphics settings
required additional actions (eg, scenery reload or restart of the sim)
When a preset is active, and properties are modified, the system will
detect this and mark the preset as edited.
For FGAIBallistic objects affected by wind, speed vector denotes airspeed.
However, submodels initialize the speed vector using ground speed of the
parent aircraft, instead of its airspeed.
In effect, this means that wind is added to the initial airspeed,
or 'wind is applied twice on initialization'.
This was very noticeable when releasing a submodel with strong sidewind:
the submodel immediately starts drifting laterally at the speed of wind.
Fix the issue by subtracting wind vector from initial speed in
FGSubmodelMgr::transform for submodels affected by wind.
Overview:
Previously Flightgear always used a single osgViewer::Viewer(), which
inherits from both osgViewer::ViewerBase and osgViewer::View, giving a
single view window.
If CompositeViewer is enabled, we instead use a osgViewer::CompositeViewer
which contains a list of osgViewer::View's. Each of these View's can have
its own eye position, so we can have multiple different views of the same
scene.
Enable at runtime with: --composite-viewer=1
Changes to allow use of osgViewer::CompositeViewer:
Previously FGRenderer had this method:
osgViewer::Viewer* getViewer();
This has been replaced by these two new methods:
osgViewer::ViewerBase* getViewerBase();
osgViewer::View* getView();
If CompositeViewer is not enabled (the default), the actual runtime state
is unchanged, and getViewerBase() and getView() both return a pointer to
the singleton osgViewer::Viewer() object.
If CompositeViewer is enabled, getViewerBase() returns a pointer to a
singleton osgViewer::CompositeViewer object, and getView() returns a
pointer to the first osgViewer::View in the osgViewer::CompositeViewer's
list.
The other significant change to FGRenderer() is the new method:
osg::FrameStamp* getFrameStamp()
If CompositeViewer is not enabled, this simply returns
getView()->getFrameStamp(). If CompositeViewer is enabled it returns
getViewerBase()->getFrameStamp(). It is important that code that previously
called getView()->getFrameStamp() is changed to use the new method, because
when CompositeViewer is enabled individual osgViewer::View's appear to
return an osg::FrameStamp with zero frame number).
All code that uses FGRenderer has been patched up to use the new methods so
that things work as before regardless of whether CompositeViewer is enabled
or not.
We make FGRenderer::update() call SviewUpdate() which updates any extra
views.
Extra view windows:
If CompositeViewer is enabled, one can create top-level extra view windows
by calling SviewCreate(). See src/Viewer/sview.hxx for details.
Each extra view window has its own simgear::compositor::Compositor
instance.
Currently SviewCreate() can create extra view windows that clone the
current view, or view from one point to another (e.g. from one multiplayer
aircraft to the user's aircradt) or keep two aircraft in view, one at a
fixed distance in the foreground.
SviewCreate() can be called from nasal via new nasal commands "view-clone",
"view-last-pair", "view-last-pair-double" and "view-push". Associated
changes to fgdata gives access to these via the View menu. The "view-push"
command tags the current view for later use by "view-last-pair" and
"view-last-pair-double".
Extra view windows created by SviewCreate() use a new view system called
Sview, which allows views to be constructed at runtime instead of being
hard-coded in *-set.xml files. This is work in progress and views aren't
all fully implemented. For example Pilot view gets things slightly wrong
with large roll values, Tower View AGL is not implemented, and we don't
implement damping. See top of src/Viewer/sview.cxx for an overview.
OpenSceneGraph-3.4 issues:
OSG-3.4's event handling seems to be incorrect with CompositeViewer -
events get sent for the wrong window which causes issues with resize and
closing. It doesn't seem to be possible to work around this, so closing
extra view windows can end up closing the main window for example.
OSG-3.6 seems to fix the problems.
We warn if CompositeViewer is enabled and OpenSceneGraph is 3.4.
Avoid passing missing add-ons to FlightGear. Since we only write a
cleaned list back to QSettings upon some user change, we can persist
bad paths.

- Removed the ENABLE_COMPOSITOR CMake flag.
- Removed /sim/version/compositor-support.
- Removed miscellaneous branching to check if the Compositor is enabled.
- Removed custom resource loader since Compositor Effects are now located in $FG_ROOT/Effects.
- Removed splash screen warning.
- Only use the Compositor versions of CameraGroup and FGRenderer.
- Fix redout/blackout not appearing under certain circumstances.
Previously the center of the airport was defined with the correct
elevation, but the runways etc. were built at 0 elevation.
This makes everything at 0 elevation so we can set the elevation
in the STG file for the moment.
Don’t probe for, or pass, missing paths to FlightGear. Since we don’t

If impatient users start multiple copies of FlightGear when a cache
rebuild is required, we can get into a mess. Use an additional
named mutex on Windows to avoid this situation, and block the secondary

* Fall back to Ocean climate if the koppen-geiger image is not found.
* Fixes to temperature calculations based on viewer and sun lat and lon.
* Fix season and day progress factors, add an autumn progress factor.
* Set the environment parameters like ice-cover, dust-cover and wetness:
for now always active, should be a menu option in the future.
* Add a compile-time option to dump a climate report to the console.
We previously only showed the magnitude of the thrust; this patch uses the sign
of first element of thrust vector. Makes things less confusing if an engine is
stopped or otherwise causing drag rather than thrust.
Uses these properties:
/sim/atis/speed
/sim/atis/volume
/sim/atis/pitch
Values 1.0 behave as default. Other values are used to multiply default
settings.
Changes don't take affect immediately. But changing com frequency seems to
often cause an update which will then pick up the new values.
Increased diagnostics from SG_WARN to SG_ALERT, to mitigate confusion if METAR
is out of date etc.
Will add a better mechanism for reporting errors at some point.
Changing style will reload style from filesystem, so one can edit styles and
see results without restarting fg.
Note that this duplicates initial populating of /gui/styles/ from
defaults.xml's <sim><gui>...</gui></sim> section, so it's a bit of a hack.
If user specified --load-tape then failure to load it should be fatal to avoid
confusion. It also avoids needlessly overwriting a valid recovery tape if
/sim/replay/recovery-period is set.
Throwing an exception was too harsh. Instead the clipping is ignored and a warning message issued.
Reintroducing the commit 90a04a that has been inadvertently removed.
These were due to the ground callback instance of FlightGear not setting the ellipse parameters of the 'contact' location. this commit make JSBSim immune to that scenario.
Includes the following new features and bug fixes:
- The <random> function now uses C++ std::default_random_engine
- WGS84 is now used everywhere in JSBSim (previously a mix of spherical/WGS84 earcth was used resulting in inaccuracies).
- A new <planet> XML element can be used to tweak the planet characteristics (such as semimajor/smemiminor axes, gravity, etc.)
- The FGGroundCallback instance is now managed by FGInertial with a dynamic pointer std::unique_ptr<>. JSBSim was previously using a static pointer which was causing memory access failures when several instances of JSBSim were used or when an instance was replaced by a new one (the structure pointed to by the static pointer was then lost when the old instance was destroyed).
- Removed calls to exit() and replaced them by exceptions that can be caught by FlightGear (should avoid FlightGear from being ungracefully stopped by an error found by JSBSim).
- Sockets interface: replaced the usage of obsolete functions gethostbyname()/gethostbyaddr() by getaddrinfo().
- FGColumnVector3 and FGMatrix33 can now be initialized by C++ std::initializer_list
- Disable the delays implemented in some flight control components during trimming (was sometimes preventing the trim algorithm from converging to a solution).
- Fixed the magnetometer initialization (was not updated during the first 1000 time steps)
- More conversions to C++11 features (nullptr, override, std::unique_ptr<>, etc.).
Since our data encoding is incompatible between 2018 and 2020, use
different settings keys so running both versions in parallel is easier.
Without this, each version screws up the data for the other.
When local aircraft scanning is slow, we can end up clearing
the locale while a scan is in progress, which crashes. Ensure we
abandon any in-progress scan when closing the launcher.

Add pop-up notification when we migrate to a new version of a hangar.
Convert the ‘new version available’ message to use a pop-up
notification as well.
Avoid filling up the logs when the launcher parses broken aircraft XML;
wait until the user actually pick one to fly with, before reporting
XML errors.
This is to avoid console/log spam from jetways.nas in particular,
which uses loadxml to probe for file existence, every 10 seconds. But
in general it seems useful to have this potentially be quiet, since
there is a result code.
AirportDyanmics::innerGetActiveRunway can unfortunately return an
empty string even when it return ‘true’. Check for this in the wrapper,
and switch to the fallback, to avoid returning a bogus runway to
other parts of the code.

This causes QApplication to become unhappy and crash, so use a
graceful exit via a new return code and FG_OPTIONS_EXIT instead.

Adjust the wording and links for these pages, after a review session

from the local installation.
Avoid 'findShortestRoute' exception by checking both the start

a traffic shutdown.

When the file path is not preset, check for this and don’t let
readProperties() fail with an exception, since this makes for very
noisy event reporting.
When starting at an airport, but not at parking or a runway, create
an empty AIFlightPlan, and ensure the AIManager code doesn’t choke on
empty FPs.
Add a unit-test which simulates the C172 tutorial reposition logic,
which is a little gnarly.
Allow mis-match of STAR and approach, which is necessary for EDDF
operations. When there’s a mismatch, just route the common section
and don’t try to build a STAR -> approach transition.
Fix by Tobias Dammers.
When reachedEndOfCruise fails, return true, so we trigger the next
phase of the flight. Without this we get stuck logging the error
message, but not progressing the flight.
- Use a range-based for loop instead of an iterator.
- Don't bother checking if the previously-visited directory was the
same: the potential saving that the previous code was hoping should be
null because FGGlobals::append_fg_scenery() doesn't add a path to
FGGlobals::fg_scenery if it's already there---this assumes that all
paths added to FGGlobals::fg_scenery go through
FGGlobals::append_fg_scenery(), of course.
This should have no effect on FG's behavior.
If a menu-bar item is missing a <name>, we can end up building a string
from nullptr, which is a SEGV.

Will back-port to LTS once verified.
Use the ‘file name copying’ version of log(), to avoid an ASan use-
after-free. Note this requires SG change
908496d43dd7c3a7ca1de42b0e0c21aa0498c7df
to work correctly.
When there are installed the same aircrafts from different sources
(fgdata + fgaddon + git) with identical descriptions, use the URI to
provide stable sorting.
Handle the standard windows-3rd-party setup (used by fgmeta) with no
extra options, and also handle the slightly odd setup we use on Jenkins.
Try to tolerate all permutations of setting MSVC_3RDPARTY_ROOT to
different places in the hierarchy.
We no longer try to guess Boost_INCLUDEDIR by looking at parent dirs of
MSVC_3RDPARTY_ROOT, since this seemed kind of bad to me. Let’s try
it and see.
Fire the release bindings for active pick callbacks, even for a ‘handled’

Attempting to fix Sentry crash FLIGHTGEAR-B, crash on shutdown. Not
sure this is quite right, but the logic is clearer and we handle
invalid iterators better.
Add a number of properties set by both AI Traffic and Swift aircraft:
gear/gear[0..5]/position-norm
surface-positions/flap-pos-norm
surface-positions/spoiler-pos-norm
surface-positions/speedbrake-pos-norm
controls/lighting/beacon
controls/lighting/cabin-lights
controls/lighting/landing-lights
controls/lighting/nav-lights
controls/lighting/strobe
controls/lighting/taxi-lights
Also improve take-off behaviour
Fix various places Valgrind identified as read-of-un-inited. Also
fix use of frequencies are integers: always use a double type explicitly,
which will make MSVC happier.
FGFX isA SGSampleGroup, but owns some SGXmlSounds, which also take an
owning ref to their sample group. Clear out the XMLSounds on unbind(),
to break the circular reference.
- fgfs --language=fr-FR now works as expected for the launcher (also with
--language=fr_FR as before): the value added by option --language to
the _languages member of FGLocale is normalized in "underscore" style
(e.g., fr_FR).
- Add-on translations must now use a hyphen in their property node names
in addon-metadata.xml (talking about children of <localized>): i.e.,
use for instance <fr-FR> there, not <fr_FR>. An exception
(addons::errors::error_loading_metadata_file) is thrown if one of
these nodes has a name containing an underscore.
Helipads were not being shown for convention airports, only for
heliports. Fix this up so helipads work alongside runways at
conventional airports, when the selected aircraft is a helicopter.
Set the menu action roles to avoid the text heuristic, which erroneously

Will pick to 2018.3, 2020.1 and 2020.2 since it’s nicely self-contained
and rather annoying.
Allow add-ons to define an FGData subdir, and support multiple —data=
command line arguments, to avoid the need to modify FG_ROOT (which might
be read-only). Allow additional data paths to be either higher or lower
priority than FG_ROOT, so that add-ons cannot replace files in FG_ROOT.
Suggested on the tracker, keep log files around longer. Currently we
keep the previous ten files.
Note we still don’t log for secondary running copies, since this would
violate the ‘only one copy can write to FGHome’ principle.

This avoids crashing when using Qt : we cannot call exit() safely since
QGuiApplication won’t shut down correctly. Instead throw a special
marker object and catch this in boostrap.
For an instance of this, see:

-D shows speed and drag values at fixed altitude.
--aD shows best speed at different altitudes.
Example:
yasim fgaddon-git/Harrier-GR3/Harrier-GR3.xml --aD
Results in tooltips for instrument needles, and control surfaces.
Enabled with /sim/rendering/automatic-animation-tooltips/enabled.
The max number of auto-created tooltips can be specified in
/sim/rendering/automatic-animation-tooltips/max-count (too many can cause
problems, e.g. on 777 i had to set max to 45).
src/Model/acmodel.cxx:fgLoad3DModelPanel(): pass new property values to
simgear::SGModelLib::loadModel(), so we can have auto-created tooltips for
animations in the user's aircraft.
[This all requires matching changes to simgear.]
We get away with things without these includes because
the build concats lots of C++ files together into
build/flightgear/src/GUI/fglauncher_autogen/mocs_compilation.cpp and luckily
earlier ones had the right includes.
Continuous replay:
If the user replays a continuous recording from file and then end replay
with the 'My controls' or 'End replay' buttons, we now forget about the
continuous recording. This enables the usual in-memory record/replay to be
used subsequently. Also added a '-continuous' suffix to continuous fgtape
filenames.
New recovery system:
If /sim/replay/recovery-period is set and greater than zero, we
periodically save a single-item continuous recording to a recovery file
called <aircraft-type>-recovery.fgtape (with no date or time in the name),
doing so in such a way as to ensure that there is always a valid recovery
file even if flightgear crashes. One can then resume the flight from the
most recently-saved point by loading this from within flightgear or with
the --load-tape=... option.
Also did a fair amount of refactoring and tried to clarify the different
property nodes that we embed within recordings.
This background recording keeps the user aircraft stationary while recording
all movements of multiplayer aircraft. Allows one to look at replay without,
for example, disturbing continuous record to file.
This allows full-fidelity recordings of arbitrary length (limited only by disc
space) to be created and replayed. These recordings always contain multiplayer
information, regardless of /sim/replay/multiplayer.
When an uncompressed recording is loaded, it is not copied into memory. Instead
we extract individual frame information as required when replaying.
Recording to file is activated by setting /sim/replay/record-continuous to
true. We use the same filename pattern as ordinary fgtapes. The file format
is similar except for being uncompressed (so that replaying can seek within
the recording; gzip etc don't seem to support seeking within the uncompressed
stream.)
Lars T identified some cases where the launcher would fail to include
local aircraft due to them using weird ways to include additional
XML into their -set.xml. Add a temporary resource provider while the
launcher is scanning, to make this work.
Will pick to LTS branch once verified.
Was being shown before locale was selected, so always using default
translation. Fixed by deferring the dialog, and also added an assert
for debug builds, if trying to access translated string too early.
With this change, “Reload Input” will discover newly attached devices
on macOS, which previously did not work.
Also add correct detection of disconnected devices, which previously
was not handled well, especially with the new ‘keep trying to open
devices’ behaviour of FGJoystickInput.
Should fix:
