Ubuntu/Debian introduced "multiarch" library directories, which is
unsupported by CMake <= 2.8.10. Add manual search paths as a workaround.
Currently it is only needed for libsvn, but it is needed for any lib
which is converted to the new directory standard.
Disable elevation mixup for naiads, since it is introducing inconsistencies between the navdata and the scenery. (Actually it's exposing inconsistencies between the airport and navaid data, but that can't be fixed right now)
This bug was caused by the code not tolerating missing navaids / waypoints. Update logic so missing navaids degenerate to basic waypoints without problem. Also tolerate present, but empty, runway properties - don't throw an exception by looking up empty identifiers.
Iterator must be reset after clearing waypoint list.
Deleting "*waypoint.end()" doesn't delete the last waypoint (end()-1
does - it is never actually used though).
When the scenery paths change, we need to rebuild the nab-cache, since Airports/ data may have changed - e.g. someone installing custom scenery with updated ILS / thresholds.
When multiple processes (right now, multiple copies of fgfs, but potentially other users in the future) access the navcache, it can cause SQLite to return a 'locked' error, so the request should be re-tried. Add code to do this.
rather than window size, since the size of full screen windows can change:
e.g. Xinerama mode automatically resizes fullscreen windows to cover the
area belonging to a single display only - so the
"(Xinerama) screen area == window size" check always failed - even in
fullscreen mode.
PositionedID is of "int64_t", which depends on platform: apparently it is
"long long int" for Mac (requiring %lld format), but it is "long int" for
64bit Linux (requiring %ld). To avoid a "compiler warning fix commit
war" ;-) use a type cast to the longest common type (long long int).
Inspired by Harald's patch, attempt to get AI models show realistic gear animations. Unfortunately AI models seem to be ignoring the gear properties, so keeping the code disabled until I can trace down why.
FGAISchedule::update can be time consuming. Preempt when necessary to
avoid simulation lags, and call it every sim iteration, until the flight
plan is complete.
ThorstenB identified some cases where mod-times changing could lead to corrupted ground-cache data in the DB - handle both of these. What's still unclear is why the mod-times changes; hopefully the additional debug info will reveal this.
to avoid repeating identical NavCache/SQL queries. Also ensures we're
not using multiple FGAirport instances for an airport - each triggering
identical queries to pull in airport data.
Airports by ICAO ID are requested very frequently at run-time, so caching
significantly boosts performance.
Track length is calculate every iteration/for every aircraft. Since some
tracks have hundreds of waypoints, calculation is slow. Cache the
track length between the waypoints ahead, so it rarely needs to be
recalculated.
AIManager had unfortunate code to pass some state to the traffic-manager; this is no longer required since traffic schedules hold onto their AI-Aircraft directly as needed.
