=head1 NAME MPMs - Multi-Processing Model Modules =head1 Description Discover what are the available MPMs and how they work with mod_perl. META: This doc is under construction. Owners are wanted. -- pgollucci volunteering =head1 MPMs Overview =head1 The Worker MPM META: incomplete You can test whether running under threaded env via: C<?> #ifdef USE_ITHREADS /* whatever */ #endif When the server is running under the threaded mpm C<scfg-E<gt>threaded_mpm> is set to true. Caveats: All per-server data is shared between threads, regardless of locking, changing the value of something like ap_document_root changes it for all threads. Not just the current process/request, the way it was in 1.3. So we can't really support modification of things like ap_document_root at request time, unless the mpm is prefork. we could support modification of modperl per-server data by using r-E<gt>request_config in the same way push_handlers et al is implemented. But it is not possible to use this approach for anything outside of modperl (ap_document_root for example). =head1 The Prefork MPM META: incomplete =head1 The Event MPM =head1 Maintainers Maintainer is the person(s) you should contact with updates, corrections and patches. =over =item * Philip M.
