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.
Allow for advanced animations using easing functions and adapters
for interpolating specific property types (eg. CSS colors).
Old behavior should not have changed.
Make position finalisation happen in the same phase as scenery load, i.e as a task during the main loop, instead of during the init loop. This is compatible with the existing reset logic. Unfortunately more work is needed; the environment code doesn't update the local station quickly enough on reset. (Fixing that is next!)
Record the historical flight-path (by default, since last takeoff). Optionally display the flight-path in the map; other visualisations (e.g., an 'in-world' view) could also be created. Nasal API to follow so Canvas-map or FMS can show the same data.
Altitude and attitude (Euler angles) are currently recorded but not used anywhere.
Modify startup sequence, so position can be modified late in the startup process, right before the scenery load starts. This allows two ugly hacks to move to a permanent, less hacky location. If other position init modes required similar late evaluation in the future, this can be accommodated now.
This is a somewhat high-risk change - I've tested both carrier starts and runway-selection based on realwx METAR, but please look out for other position-init issues and test before / after this patch.
Add missing ATIS elements (transition level, expected approach,
precipitation, runway surface warnings).
Minor phraseology fixes for US/Europe.
Adds "/sim/atis/concise-report" option to use abbreviations (CAVOK etc),
and omit "obvious" units (depends on airport).
Trigger ATIS updates for significant pressure changes.
For (future) easier testing of the sim, support a mode where only explicitly named config / option files are loaded, instead of the default ones. (Including, for example, preferences.xml). This currently produces a non-functional sim, but will soon be more useful :)
No behaviour should change unless you try the new option.
Avoid the application becoming unresponsive during nav-cache rebuilds. We still have to wait for the rebuild, but perform it on a helper thread so the main GUI thread stays responsive and hence doesn't trigger a beach-ball / 'not responding' alert. Also ensures there's some feedback (the spinner) during the rebuild operation, so users don't think we've hung.
so they can instantly adjust to the changed environment.
(Not fully working yet, since some environment settings, like environemnt
pressure/temperature, still changes slowly after a sim reset - instead of
immediately jumping to the new setting. Also, METAR sometimes arrives too
late...).
Break some subsystem dependencies, by explicitly using properties to read the primary position, orientation and velocities. (Instead of directly accessing the primary model placement). This means a couple more globals can die.
Cache the parsed navigation and airport data in a binary file to reduce
startup times and memory consumption (since only referenced FGPositioned
elements are held in memory).
Data will be reimported when the mod-time of any input file is changed.
If a global file is changed (nav.dat, awy.dat, apt.dat, etc), the cache
will be completely rebuilt, which takes approximately 30 seconds on
moderate hardware. (Future work may reduce this).
Separate other init functions from position init, since they are unrelated, and made fg_init.cxx very complex. Next step will be brining some sanity to the position init logic :)
(Requires latest SimGear!)
Break fgInitSubsystems into several phases - subsystem creation, then binding and then init. Run init over multiple main-loop iterations so the application stays responsive to GUI/OS events during init.
There should be no behaviour changes due to this, except that during init Windows and OS-X should no longer show the beach ball / 'application not responding feedback', hopefully.
so package builders don't need local patches.
Also, instead of hardcoded firefox, use "xdg-open" or "sensible-browser"
launchers on Linux, to auto-detect user's preferred browser.
Override with cmake switch -DWEB_BROWSER=...
(Not affecting Mac/Win which are hard-coded anyway).
- Refactor CanvasMgr into PropertyBasedMgr to be also used
for the Canvas GUI system.
- Get rid of tied properties in the Canvas system.
- Add new placement type 'window' for placing canvases onto
windows
- Pass mouse events to Window class (only if cursor is over
window)
- Refactor canvas placement clean up
Sink the 2D panel logic into FGPanelNode, simplifying
renderer.cxx and a few other places. Also allows potential
for unloading / paging of 2.5D panels in the future.
Not every xml-autopilot filter needs to run at the update rate
of the FDM. This only makes sense for the autpilot filters. Those,
who update instrument needles or environment properties for example
may run at frame rate.
This patch (thanks to ThorstenB, who is the author) forces those
filters defined in /sim/systems/autopilot into the FDM loop and those
defined in /sim/systems/property-rule into the default loop. They
show up as xml-autopilot and xml-proprules in the performance monitor
