[geos-devel] GEOS 2.2.2 C API + Reference counter

[Mateusz Loskot]

Hi,

As we talked yesterday, I applied small changes
with reference counter to make
initGEOS/finishGEOS more safe.
I applied those changes to GEOS 2.2.2.

Here is the package with geos_c.h/cpp files:

http://mateusz.loskot.net/tmp/geos-capi-refcounted.tar.bz2

Original version of GEOS 2.2.2 crashes in following situation:

initGEOS(NULL, NULL);
finishGEOS();
finishGEOS(); // <--- BUM!

Now, changes described above, make it safe to call init/finishGEOS
multiple time, no matter in what order.

I think this small patch could be applied to GEOS 2.2.2 as a backport.

If case of comments, just give me a note.

Cheers
