cvs commit: jakarta-tomcat/src/share/org/apache/tomcat/core ContextManager.java Request.java
costin 01/04/21 11:36:08
Modified: src/share/org/apache/tomcat/core ContextManager.java
Request.java
Log:
Core changes !!!
engineShutdown() hook is supposed to be called when tomcat is shut down ( and modules
must clean up resources ). The interceptor can be added/removed at any time -
it must clean after itself on removeInterceptor - but it shouldn't get a shutdown
notification when it's removed ( since the server will still work ).
Also, shutdown will no longer remove contexts - since init() didn't add them. Whoever
adds the contexts ( i.e. config modules ) should also remove them - if they want -
on server stop/restart. ( the context should be cleaned up on contextShutdown, but
it may remain added - the server will report "application unavailable" instead of
not found ).
Also, shutdown will not remove interceptors - since it didn't add them.
A init->start->stop->shutdown whould return to the same state as before init
( i.e. the configuration hardcoded in context manager like modules and settings
must remain ).
A shutdown->init should bring the server in ready state, and after start it should
work as before.
