On httpd there was a discussion regarding versioning, and this got me thinking...
Included in the APR 1.5.1 changes is an internal change to how apr_shm_create(), when using APR_USE_SHMEM_SHMGET, calculates the key (via ftok())... The problem (see the Bugz report) was that using the constant 1 would cause collisions, so I adjusted it to use a hash of the filename. The problem there is that any external APR users that needed to also determine the key needs to be aware of that. And from what I can see, there is no easy way to do that. So I will be pulling that from 2.0-dev and 1.5-dev until we can figure out a better way. Ideas appreciated.
