Subject [Httpd Wiki] Update of "ModuleLife" by MarcMongenet
Date Thu, 18 Oct 2007 01:14:33 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Httpd Wiki" for change notification.

The following page has been changed by MarcMongenet:
http://wiki.apache.org/httpd/ModuleLife

The comment on the change is:
== Locking through graceful restart ==

------------------------------------------------------------------------------
                                   APR_LOCK_DEFAULT, pconf);
  }}}
  
+ == Locking through graceful restart ==
+ During a graceful restart, old children are still serving old requests while new children
are serving new requests. If the same lock must be used by old and new children, then the
lock name must be the same and cannot be generated with tmpnam() or similar functions.
+ 
  == Preventing module unloading ==
  To prevent module unloading, there is a ''sick and twisted hack'' (wrowe dixit): "the evil
method is to use apr_dso_load() against the process pool to load it 'permanently'".
