Subject [jira] [Commented] (SYNCOPE-1386) Not committed managed objects can get into L2 cache.
Date Fri, 19 Oct 2018 18:52:00 GMT


DmitriyB. commented on SYNCOPE-1386:

 Do you have the property like "l2CacheClearTimeOut" setting which is responsible for clearing
the L2 cache if nothing is happening with it?

> |Hi guys. I noticed the issue that leads to inconsitent data that comes in response. 
> In Apache Syncope the Application Scoped Entity manager is used for all operations with
the database. Entity manager is created by appropriate Entity Manager Factory that matches
a particular domain. Thus, the scope of Persistence Context is extended and also it is bound
to a current thread. 
> Moreover, Entity Manager that is created by Entity Manager Factory is Transactional.
Thus any execution using entity manager without opened transaction leads to exception like: 
>  {code:java}
> java.lang.IllegalStateException: Could not find EntityManager for domain dbrashevets 
> at org.apache.syncope.core.persistence.jpa.dao.AbstractDAO.entityManager(
> at org.apache.syncope.core.persistence.jpa.dao.JPAUserDAO.findByUsername(
> at sun.reflect.GeneratedMethodAccessor232.invoke(Unknown Source) ~[?:?]

> {code}
> In Apache Syncope L2 cache is enabled by default. 
> syncope-core-persistence-jpa-2.0.8.jar!\domains.xml file has a property {code:java}
> <entry key="openjpa.DataCache" value="true"/> 
> {code}
> Here is the use-case how to reproduce the problem: 
> 1. Create user in Syncope 
> 2. Do a request password reset action and make sure that token that is used for pwd reset
action is generated and stored into database. 
> 3. Restart your application to be sure that L2 cache is empty. 
> 4. Confirm password reset action for this user and make sure that requested password
doesn't apply the password rules. In my case password is too short. The exception like "InvalidUser:InvalidPassword:
Password too short" should be thrown. 
> 5. Request the user by username. The user that comes in HTTP Response doesn't have "token"
and "tokenExpireTime" attributes. But you may find "token" and "tokenExpireTime" value in
SyncopeUser table for this user. 
> I also noticed that ~ after 5 minutes left the L2 cache is gone.
> You can find an example in script. Run this command to execute
the scirpt: 
> "./ \| tee temp.log" 
> Here I'm trying to do confirm-password-reset action after 5 minutes of waiting with the
password that doesn't match the rules. And then I'm requesting user by username. In response
it comes without "token" and "tokenExpireTime".
