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.
In this section we highlight some of the articles on the web
that are of interest to Apache users.
