The big topic of discussion this week has been the interaction between subrequests and filtered I/O in Apache 2.0. In Apache 1.3 when a subrequest was made (for instance, to gather in a "include" document in an server-parsed page), the response could be written directly to the network. In Apache 2.0 the situation is different, as the response must pass through the filter chain, to allow other filters to process the response. A severe bug in this complex interaction was un-earthed this week and is not yet fixed, although several fixes are being discussed.

A major change to the processing of 'graceful restarts' in Apache 2.0 has been committed by Ryan Bloom. A "pipe of death" is used between the parent and child processes to tell the children when to exit. To force the child processes to wake up if they are waiting for a new connection, the code takes the unusual step of making a connection to the listening port (e.g. port 80).

Last week in Apache Week issue #249, we reported that crackers gained access to apache.org but no evidence of source of binary modifications were found. Kurt Seifried at SecurityPortal analyses how Apache.org was compromised, interviews Brian Behlendorf, President of the Apache Software Foundation, and concludes that it is all a matter of trust.
