Remove uses of .str(), .c_str() and some other methods of SGPath.
Pass SGPath directly where possible, or explicitly convert to the
appropriate 8-bit encoding.
After removing /Models from FGData loading of shared models from
within a scenery model failed because the ResourceManager did not know
about additional scenery paths.
Avoid intermittent race conditions on shutdown when the OSG
pager/Db thread is running. Ensure the OSG threads are stopped before
we start tearing down any scene graph nodes.
* If one has the same aircraft in several aircraft directories,
FlightGear should not mix resources from the various aircraft
directories. For instance, if one starts FG with:
--fg-aircraft=/my/personal/dir:/path/to/fgaddon/Aircraft
and one has in /my/personal/dir/ec130 a clone of the upstream
developer repo, FlightGear should use either the upstream version from
/my/personal/dir/ec130 or the FGAddon version from
/path/to/fgaddon/Aircraft/ec130, but not some strange, untested hybrid
of both.
* This commit makes sure that when the looked-up resource starts with
Aircraft/<ac>, where <ac> is the current aircraft name [last component
of aircraftDir = fgGetString("/sim/aircraft-dir")], then
AircraftResourceProvider::resolve() doesn't search other aircraft
directories if the resource isn't found under 'aircraftDir'.
* To reproduce the bug before this commit, you may add the following
code (there is nothing specific about the SenecaII here, it's just the
aircraft I used for testing):
var file_path = resolvepath("Aircraft/SenecaII/flo-test");
if (file_path != "")
gui.popupTip("flo-test found", 2);
else
gui.popupTip("flo-test not found", 2);
in a keyboard binding for the SenecaII (for instance; you may use the
F11 binding that otherwise only prints a short message). You should
add this to the SenecaII/SenecaII-base.xml file *that will be loaded
by FlightGear*, let's say the one under /my/personal/dir in the
example above (beware of the <path-cache> in autosave_X_Y.xml). Then,
by creating or removing a file named "flo-test" in the SenecaII
subdirectory of other aircraft dirs (for instance,
/path/to/fgaddon/Aircraft in the example above), you can see that the
behavior of the loaded aircraft is influenced by the contents of
unrelated versions of the same aircraft that might be present in other
aircraft dirs (e.g., loaded /my/personal/dir/SenecaII influenced by
/path/to/fgaddon/Aircraft/SenecaII).
* Aircrafts loading resources using paths relative to the current
aircraft directory (e.g., with 'resolvepath("flo-test")') are not
affected by this kind of problem, because this scheme is handled by
CurrentAircraftDirProvider, which does not exhibit this bug.
- /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
Adapt to corresponding SG change to make SGMaterialLib be ref-counted,
and have the 'reload-materials' command notify the tile-manager of this,
so it can update the options struct it passes to new tiles.
Warn (but do not require, since people would probably complain) when
added paths do not contain an Aircraft subdir. When people specify
a path which ends in /Aircraft, use the parent directory.
- borrow some code from the new reset codepath to cleanly stop the
OSG pager thread during normal shutdown. Avoids a race-condition
destroying various structures the pager thread might be modifying.
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)
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.
Remove various hacks and make magvar work like a normal subsystem, as part of the environment manager. Fix the remaining users of the globals->get_mag accessor, and hence kill off the global pointer.
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.
FGFX objects must be dereferenced early enough, and sound manager must be
removed late enough - otherwise openal complains about resources being
still in use when tryin to remove buffers.
Also: do not create FGFX objects for AI/MP aircraft, when AI sound is
disabled.
Fixed ugly sim-reset issue: Persistent properties (USERARCHIVE attribute)
are retained across sim sessions (when restarting the sim). So they should
also be retained on sim-resets (without the need to first exit/restart
the sim to make them really persistent).
Also, avoid warning due to read-only properties.
Untieing needs to be done prior to the destruction of the object which
aggregated the TiedPropertyList. So the TiedPropertyLists destructor can't
untie the properties automatically (and it doesn't). So, do some manual
clean-up.
