at (lon, lat) coordinates -1000,0. This patch fixes the AIModels/Traffic
Manager side of things. The AIModels subsystems allowed the creation of
AIAircraft with non-existent 3D models. If such a model didn't exist, the
aip class didn't get initialized, resulting in the above-mentioned bogus
position information. Here I circumvent this problem by a) only interacting
with the tile loader if the model is visible (and hence has succesfully been
initialized) and b) by disallowing the traffic manager to create AIAircraft
objects if the path to the 3D model doesn't exist.
bunch of memory leaks that had accumulated over the years. FlightGear
doesn't currently bother to destroy and recreate a YASim context, but
at least it can do so now without worry.
groundcache addition -- the ground callback doesn't do anything at
solution time, so the ground plane was unset. Valgrind was whining
about this; it's not clear that it was actually causing a problem.
a race condition ending in warping twice and having huge increments for the
second warp.
I am not aware of such a flush function in glut. So we emulate that by
ignoring mouse move events between a warp mouse and the next frame.
That should make glut behavour aequivalent to sdl behavour.
This isn't the case if the model is destroyed on fgfs exit. To make <unload>
work under these circumstances, one would have to reorder subsystem removal,
but this doesn't seem overly useful, so we'll do it when we really need it.
aircraft models this is only called if they are loaded as AI, not if they
are the model flown by the human pilot. This has technical reasons (too
soon for Nasal/fg), but is useful to distinguish AI and non-AI use, for
example to set a different livery for AI models, or to set different
animation properties.
implement FGNasalModelData class for execution of XML <load> and <unload>
scripts. modelLoaded() is called by the model loader, and the destructor
on branch removal.

make scenery and custom objects run their Nasal scripts on loading
and unloading. Let OBJECT_STATIC object not be cached.
<nasal>
<open>print("I'm called on dialog open")</open>
<close>print("I'm called on dialog close")</close>
</nasal>
All Nasal runs in a dialog namespace, so that variables and functions
defined in the <open> block can be used in <binding>s, etc. This is
especially useful for <radio> button handling. See "location-in-air.xml".
mf:
pthread_cancel doesn't seem to work correctly on all supported platforms.
It apparently causes SGBlockingQueue::pop() to correctly leave the thread on
the cancellation point pthread_wait(), but the SGGuard() destructor isn't
called, so the queue mutex remains locked. This triggered an assert() on
pthread_join(). This patch uses an empty ICAO request as signal for the
thread to terminate itself.
I have implemented a Honeywell MK VIII EGPWS emulation for FlightGear.
The MK VIII is an Enhanced Ground Proximity Warning System aimed at
regional turboprop and small turbofan aircrafts such as the Citation,
Citation Bravo, B1900D, Beechcraft 99 and L410.
Frederic Bouvier:
make the MSVC compilation possible. Rearrange base package directories.
The original code selected the most preferable runway combination,
regardless of which combination was currently active. This patch
builds in some additional resistance against change, by keeping
track of which runways are already in use, and forces a change
in active runways only when new (wheather/time of day) conditions
force it to do so, resulting in much more consistent runway assignment.
behavior.
and in the calculation of the launchbar angle (by Vivian).
It also calculates the holdback angle, and sets a Boolean value which
can be used to initiate the release of the catapult strop submodel at
the appropriate moment (new code by Vivian).
