Hi
as some of you will certainly know there's a discussion thread
developing between Alexandre Ferrieux and Gustav Neumann which will
certainly impact mod_rivet 2.2 series and the future 2.3 series when
using mod_prefork_mpm.
They're moving to a new handling of Unix fork calls removing the
pthread_atfork call that proved to be an easy way to have a working
notifier in child processes (that call was introduced upon Harald's
suggestion if I remember correctly). We'll have a way to restore the
notifier anyway, but using this feature of mod_rivet will require a more
accurate documentation of the implications and caveats.
For what I understand the new fork handling could slip into the next
8.6.x release and therefore Tcl installation all around could be
upgraded breaking existing installation of mod_rivet to handle
asynchronous I/O. It's important we prepare to roll out a new 2.2.4
release able to transparently handling the 2 ways to prepare the fork as
soon as a strategy is adopted (lazy notifier initialization for what I
can understand)
