In https://bz.apache.org/bugzilla/show_bug.cgi?id=59840 the issue crept up that StdEnvVars makes concurrent access to the SSL context when HTTP/2 is in place.
The question is: how do we want to fix this? The general theme is that a module needs to perform some action on a connection, sees that it is a slave connection and accesses the master instead. Such a module needs to be aware that access to master may happen in parallel with other request. Should we let each such module care for it on its own or do we want to provide a way to access the master connection in a mutex protected way? -Stefan
