[jira] [Created] (KARAF-985) LDAPLoginModule generates a large
number of DirContext objects
LDAPLoginModule generates a large number of DirContext objects
--------------------------------------------------------------
Key: KARAF-985
URL: https://issues.apache.org/jira/browse/KARAF-985
Project: Karaf
Issue Type: Bug
Components: karaf-config
Affects Versions: 2.2.4
Environment: Karaf 2.2.5-snapshot
Reporter: metatech
Priority: Minor
In class org.apache.karaf.jaas.modules.ldap.LDAPLoginModule, "DirContext.close()" and "NamingEnumeration.close()" are not called in all cases.
Although it is not mandatory, it would be better to call it in all cases (to be sure, in a "finally" block).
http://download.oracle.com/javase/tutorial/jndi/ldap/close.html
Otherwise, this leaves one "com.sun.jndi.ldap.Connection" thread running for each LDAP request. After several minutes, the thread disappears automatically.
During a performance test with 10 concurrent users, this creates up to several hundreds of such threads.

metatech commented on KARAF-985:
--------------------------------
There is still one bug with the fix :
In step 1, the "hasMore" is not called after the "next" is called, so the naming enumeration is not automatically closed.
Here is the complete fix :
[192] SearchResult result = (SearchResult) namingEnumeration.next();
[193] userDN = (String) result.getName();
+ namingEnumeration.close();
With the complete fix, maximum 10 LDAP connections are simultaneously in "ESTABLISHED" state (in netstat) with 10 concurrent users, instead of hundreds.
Beware that there are still cases (although I cannot give an practical example) where a NamingException might be thrown by "next" or "hasMore", in which case the naming enumeration would not be read up to the end.

Glen Mazza commented on KARAF-985:
----------------------------------
The JavaDoc for NamingEnumeration.close()[1] says "If an enumeration proceeds to the end--that is, until hasMoreElements() or hasMore() returns false-- resources will be freed up automatically and there is no need to explicitly call close()." For two out of the three cases with NamingEnumeration in this file, either of the two methods above will indeed return false, so close() shouldn't be needed then. I did add in a close() in the proposed patch for the third case.
For DirContext(), I added in close() in the two of three scenarios where it wasn't already being called.

> In class org.apache.karaf.jaas.modules.ldap.LDAPLoginModule, "DirContext.close()" and "NamingEnumeration.close()" are not called in all cases.
> Although it is not mandatory, it would be better to call it in all cases (to be sure, in a "finally" block).

> Otherwise, this leaves one "com.sun.jndi.ldap.Connection" thread running for each LDAP request. After several minutes, the thread disappears automatically.
> During a performance test with 10 concurrent users, this creates up to several hundreds of such threads.
