Hi there,
a colleague of mine observed a change in behavior starting with TC
9.0.38: until 9.0.37 the default server.xml with the connector
protocol="HTTP/1.1", installed tcnative and attribute
useAprConnector="true" for the AprLifecycleListener actually starts an
APR connector as documented and expected:
INFO [main] org.apache.coyote.AbstractProtocol.init Initializing
ProtocolHandler ["http-apr-8080"]
Same situation starting with 9.0.38 (and at least until 9.0.44):
INFO [main] org.apache.coyote.AbstractProtocol.init Initializing
ProtocolHandler ["http-nio-8080"]
I increased log level for a coupe of packages to FINEST and see the
following differences during startup:
FINE [main] org.apache.tomcat.util.IntrospectionUtils.setProperty
IntrospectionUtils: setProperty(class
org.apache.catalina.core.AprLifecycleListener SSLEngine=on)
FINE [main] org.apache.tomcat.util.digester.SetPropertiesRule.begin
[SetPropertiesRule]{Server/Listener} Setting property 'useAprConnector'
to 'true'
FINE [main] org.apache.tomcat.util.IntrospectionUtils.setProperty
IntrospectionUtils: setProperty(class
org.apache.catalina.core.AprLifecycleListener useAprConnector=true)
### ONLY ADDRESS DIFFERENCE
-FINE [main] org.apache.tomcat.util.digester.SetNextRule.end
[SetNextRule]{Server/Listener} Call
org.apache.catalina.core.StandardServer.addLifecycleListener(org.apache.catalina.core.AprLifecycleListener@383534aa)
+FINE [main] org.apache.tomcat.util.digester.SetNextRule.end
[SetNextRule]{Server/Listener} Call
org.apache.catalina.core.StandardServer.addLifecycleListener(org.apache.catalina.core.AprLifecycleListener@136432db)
FINE [main] org.apache.tomcat.util.IntrospectionUtils.callMethod1
IntrospectionUtils: callMethod1 org.apache.catalina.core.StandardServer
org.apache.catalina.core.AprLifecycleListener
org.apache.catalina.LifecycleListener
FINE [main] org.apache.tomcat.util.digester.ObjectCreateRule.end
[ObjectCreateRule]{Server/Listener} Pop
org.apache.catalina.core.AprLifecycleListener
#### WRONG CLASS CHOSEN IN NEWER VERSIONS
-FINE [main] org.apache.tomcat.util.IntrospectionUtils.setProperty
IntrospectionUtils: setProperty(class
org.apache.coyote.http11.Http11AprProtocol port=8080)
+FINE [main] org.apache.tomcat.util.IntrospectionUtils.setProperty
IntrospectionUtils: setProperty(class
org.apache.coyote.http11.Http11NioProtocol port=8080)
FINE [main] org.apache.tomcat.util.digester.SetPropertiesRule.begin
[SetPropertiesRule]{Server/Service/Connector} Setting property
'protocol' to 'HTTP/1.1'
...
and after these lines the logs use consistenly APR versus NIO in the two
versions. Both startup logs show the same
INFO [main] org.apache.catalina.core.AprLifecycleListener.lifecycleEvent
Loaded Apache Tomcat Native library [1.2.27] using APR version [1.7.0].
INFO [main] org.apache.catalina.core.AprLifecycleListener.lifecycleEvent
APR capabilities: IPv6 [true], sendfile [true], accept filters [false],
random [true].
INFO [main] org.apache.catalina.core.AprLifecycleListener.lifecycleEvent
APR/OpenSSL configuration: useAprConnector [true], useOpenSSL [true]
INFO [main] org.apache.catalina.core.AprLifecycleListener.initializeSSL
OpenSSL successfully initialized [OpenSSL 1.1.1k 25 Mar 2021]
I didn't find an obvious reason in the changelog. Maybe an unwanted
backport part from 10 or some startup order change.
I have not yet checked 8.5 etc.
Regards,
Rainer
