Eric, thanks for the help! When enabling mod_logio it became immediately clear that mod_h2 wrongly prevented some pre_connection hooks to run. mod_logio however expects its allocated module config to be there when a request gets cleaned up... So, with v0.7.2 all pre_conn hooks are run again and it is part of my test setup now.
Which adds the issue about proper handling of module configurations in pseudo connections. There seem to be two approaches: a) treat pseudo connections like real ones -> run all connection hooks b) treat them as "shadows" of the real connection -> copy module configs While a) is the least dangerous, it misses gives a false impression about the properties of a connection. For example, mod_h2 currently copies over the mod_ssl config, so that SSL variables are available during request processing on pseudo connections. On the other hand, code is not really prepared for b) since this means that many threads may operate on the same module config. So, mod_h2 now follow a) for now (with the exception of mod_ssl). A future proposal for pseudo connections will need to reevaluate this.
