Catching loader thread on subsystem destruction is too late, since it
depends on other subsystems (which are destroyed earlier).
=> Need to stop & join thread during subsystem shutdown.
Also changed loader sleep logic - to avoid excessive delays (up to
30 seconds) on shutdown.
(Issues mostly happened when running offline with realwx enabled.)

work again. These options now write properties in the
/environment/config/presets
branch. The values will be applied in the property-rules
in FGDATA/Environment/interpolator.xml
This patch enables multiple MetarProperties instances tied to the
property tree. For each node's value of /environment/realwx/metar
one MetarProperties instance is created and tied to the property
tree named there. (See FGDATA/Environment/environment.xml for details)
At least one instance will be created to provice backward compatibility
to the existing live-data weather system. This instance (tied to
/environment/metar) fetches a METAR for the nearest airport at a regular
schedule. All other instances fetch a report for airports named in the
property station-id. It re-reads the report every 15 minutes, the
remaining time until the next fetch will be scheduled is in the property
time-to-live. This property can be written to, to extend the live of
this report or schedule an immediate reload by setting it's value to zero.
This patch also provides magnetic variation for the station's location.
If "Live data" was disabled in any way in the global-weather dialog
and reenabled later, the next metar fetch occoured only after up
to 15 minutes after the report expired. This patch triggers triggers
an immediate fetch of a metar after enabling live data.
For the time being, this works only with 3d clouds disabled.
When enabled, limit the top of the misty layer to the bottom of
a possible cloudlayer above.
The automatic runway selection code in startup.nas depends
on a valid metar before /sim/signals/nasal-dir-initialized
is fired. If the METAR arrives after that signal, no automatic
runway selection is performed. This patch waits for a METAR
on the first update() loop of the subsystem.
This is the initial commit for a reworked environment controller.
The main intention is to decouple the individual modules like
metar fetch, metar properties, environment interpolation etc.
to make it easier for other weather module developers to modify
environment settings.
As a side effect, the dialogs for weather-scenario, weather-conditions,
clouds and precipitations have been merged into a single dialog
- use max. computation time instead of max computations per frame
- restart computation of an area only after significant movememt
- let the area move with a heading and a speed
This is the first part of the local-weather implementation
of Thorsten Renk, currently written entirly in Nasal. Here
comes the terrain-sampling subsystem as a first step. It is
not (yet) included in the build process which will be
performed when the system has a little matured.
This fix (re)enables the setting of temperature and
dewpoint from the weather-conditions dialog and other
sources for various altitude layers. These temperatures
are reduced to the corresponding sea level temperatures
according to ICAO standard atmosphere which is the inverse
function of the calculation of temperature at altitude based
on sea-level-temperature.
Note: this only works for the troposphere.
