- /sim/aircraft can be set to package ID, including qualified
package ID. If not matching package is found, falls back to
traditional search of fg-aircraft for -set.xml files
This is too destructive for many established things, so revert it.
Instead, make the FDM shell save /fdm state on postinit(), and
restore it on re-init (which reposition invokes).
- use old-style reset as the basis for a lightweight 'reposition' command. This does not restore state, or reset
time management, but does reset the FDM and re-finalize position.
Had to add this to FGGlobals, since it needs to be cleaned up
alongside the sound manager (which ideally it would be owned by,
but that's a change for another day)
Write PID file to FG_HOME, use this to detect multiple launches.
When this situation is detected, set a marker property and place various
objects into read-only mode, such as the NavCache and TerraSync.
PID file is created using open+unlink semantics on POSIX, and
DELETE_ON_CLOSE on Windows, so it will be removed when fgfs exits,
even if killed or crashes.
This allows us to display a platform-native dialog for problems
which occur early in startup (before we can show a PUI/Canvas dialog).
In particular this improves feedback where FG_HOME, FG_DATA or
aircraft selection is wrong, all of which happen very early in startup.
- default to SUBSYSTEM:WINDOWS (we can still AllocConsole if needed)
- add --console option to get a console on Windows
- ensure --show-aircraft and --help modes show the console automatically.
- restore-defaults kills the nav cache, terra-sync cache
- new ignore-autosave option bypasses autosave.xml and leaves it
untouched (does not over-write on exit)
Replace many lingering calls to exit() from the code,
replacing most with exception throws, which can be
caught by the existing mechanisms.
Update the option-parsing code to return an explicit
value indicating what to do (e.g., exit status to return
to the shell).
- Enable the terrasync persistent cache
- Ensure terraysync scenery dirs exist before NavCache init, so the paths are stable
- Notify TerraSync on reposition, so we sync the full 3x3 set of tiles.
