Description John Morrissey 2009-07-06 15:15:39 UTC 
mod_rewrite generates spurious warnings:

[Mon Jul 06 21:03:10 2009] [warn] mod_rewrite: Running external rewrite maps without defining a RewriteLock is DANGEROUS!

when external maps (prg:) are configured and APR_LOCK_DEFAULT uses a method that does not require an external file (APR_USE_SYSVSEM_SERIALIZE, for example).

Dunno if using apr_proc_mutex_defname() in mod_rewrite to only issue this warning for methods that require files is useful.

2.4.x doesn't have this warning any more.
