Incorporating the shared ptr code:
- All scenegraph references from SimGear
- SGMaterial which already had a reference counter uses now that common
infrastructure.
- SGMatModel is now counted.
- SGSoundSample from SimGear
- And the corresponding change for the sound samples in flightgear which fixes
a latent crash if FGBeacon would evern be deleted.
This patch fixes this SimGear compile error on x86_64 Fedora Development with gcc-4.1:
placement.hxx:49: error: extra qualification ‘SGModelPlacement::’ on member ‘init’
Add the basic infrastructure for a reference counter class.
Adding it now (without using it) enables Mathias and others to
prepare some memory reduction code.
Fix a problem where the directory being created is made relative when in fact
it's absolute. It also tightens things a bit on the Windows side.
Erik:
Make the section that splits up the directory in a lists of parent directories
a standalone function.
The create_dir was totally broken. No function was used at the right place
except mkdir. This patch now create directories without segfaulting.
Erik:
This was my bad, I've been using a really slow computer for the last ten months
and recompiling SimGear with a change to the properties code takes ages, so
once in a while I apply something not entirely tested. This is one really bad
example which shouldn't have happened. Thanks to Frederic for fixing it.
* in some cases more specific sg exception types were used in place
of the more generic one, e.g., sg_io_exception instead of sg_exception
when the context of the error was an IO error
* in some cases, the error message was made more specific
* minor style fix for exception rethrowing --- using throw; whenever
a re-throw is made; sometimes optimizing away the exception symbol name
in the catch handler at all
* more specific catch handlers added in some places -- e.g.,
an sg_io_exception caught ahead of sg_exception
to pop themselves down while the simulator is paused.
The problem was with the "real time" queue in the event manager,
causing the third argument of Nasal's settimer() (a flag for "sim
time") to be ignored. Inverts the default sense of the argument, as
there are lots of uses of settimer() in the current code, almost none
of which want to use real time.
Note this fix introduces a header file incompatibility in SimGear --
be sure to update.
