[JBoss JIRA] Created: (JBREM-1074) Config Guide should clarify the HTTP transport vs Servlet

by Andrew Oliver (JIRA)

Config Guide should clarify the HTTP transport vs Servlet --------------------------------------------------------- Key: JBREM-1074 URL: https://jira.jboss.org/jira/browse/JBREM-1074 Project: JBoss Remoting Issue Type: Bug Security Level: Public (Everyone can see) Reporter: Andrew Oliver http://docs.jboss.org/jbossas/unified_invoker/UnifiedInvoker_guide.html describes changing to use HTTP as a transport. Meaning JBoss remoting launches its own HTTP server. This is probably a pretty esoteric configuration and most people are probably looking for this: http://www.jboss.org/community/docs/DOC-9632 instead. The guide should clarify WHAT that is and where to find what you're probably REALLY looking for. (you probably don't want to run on some weird port if you're using HTTP and most installs probably run WITH tomcat which means you need to run through TC or have a totally separate IP which is pretty hard to do in most environments) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBREM-1144) Extend connection identity to server side

by Ron Sigal (JIRA)

Extend connection identity to server side ----------------------------------------- Key: JBREM-1144 URL: https://jira.jboss.org/jira/browse/JBREM-1144 Project: JBoss Remoting Issue Type: Feature Request Security Level: Public (Everyone can see) Affects Versions: 2.2.3, 2.5.1 (Flounder) Reporter: Ron Sigal Assignee: Ron Sigal Fix For: 2.5.2 (Flounder), 2.2.3.SP1 In JBREM-1128 "Introduce connection identity concept" and JBREM-1132 "CLONE [JBREM-1128] - Introduce connection identity concept", the server was equipped to recognized when a client had been replaced by another client. In other words, clients were assigned an identity. This concept should be extended to the server side, so that ConnectionValidator can detect that a server has been replaced. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBREM-1226) Sockets created by bisocket secondary ServerSocket should be configured properly

[JBoss JIRA] Created: (JBREM-1227) Fix deadlock between MicroRemoteClientInvoker and RemotingClassLoader

by Ron Sigal (JIRA)

Fix deadlock between MicroRemoteClientInvoker and RemotingClassLoader --------------------------------------------------------------------- Key: JBREM-1227 URL: https://jira.jboss.org/browse/JBREM-1227 Project: JBoss Remoting Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 2.5.2.SP3 (Flounder) Reporter: Ron Sigal Assignee: Ron Sigal Fix For: 2.5.2.SP4 (Flounder) The following deadlock can occur: 1. Thread T1 reads a response with an object whose class is not available locally, so it uses its org.jboss.remoting.loading.RemotingClassLoader to try to download the class a. java.lang.ClassLoader.loadClassInternal() acquires a lock on itself (an instance of RemotingClassLoader) b. RemotingClassLoader uses its copy of an org.jboss.remoting.loading.ClassByteClassLoader to try to download the class c. ClassByteClassLoader calls org.jboss.remoting.MicroRemoteClientInvoker.invoke(), which tries to synchronize on MicroRemoteClientInvoker.class as it sets up an UnMarshaller with a ClassLoader 2. Thread T2 attempts to make an invocation a. MicroRemoteClientInvoker.invoke() acquires a lock on MicroRemoteClientInvoker.class b. MicroRemoteClientInvoker.invoke() calls the synchronized method RemotingClassLoader.setUserClassLoader(), which tries to acquire a lock on the RemotingClassLoader Deadlock. The only two synchronized methods in RemotingClassLoader are setUserClassLoader() and unsetUserClassLoader(), which are both called from MicroRemoteClientInvoker.invoke(). The call to setUserClassLoader() is already done while the MicroRemoteClientInvoker.class lock is held. If the call to unsetUserClassLoader() is made with the same lock, then setUserClassLoader() and unsetClassLoader() don't have to be synchronized. That will eliminate the deadlock because step 2b is removed. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBREM-1230) Client hangs when hitting MaxPoolSize with idleTimeout

by Takayoshi Kimura (JIRA)

Client hangs when hitting MaxPoolSize with idleTimeout ------------------------------------------------------ Key: JBREM-1230 URL: https://jira.jboss.org/browse/JBREM-1230 Project: JBoss Remoting Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 2.2.3.SP1, 2.2.2.SP9 Reporter: Takayoshi Kimura 1. In SocketServerInvoker.processInvocation(), clientpool.wait() is called when hitting MaxPoolSize 2. SocketServerInvoker$IdleTimerTask calls ServerThread.shutdown() and remove it from clientpool when it's timed out in idle state 3. ServerThread.shutdown() doesn't call clientpool.notify(), so #1 doesn't resume although there is free slot available -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBREM-981) CLONE [JBREM-980] - ServerInvokerServlet should retrieve ServletServerInvoker based on updated InvokerLocator

by Ron Sigal (JIRA)

CLONE [JBREM-980] - ServerInvokerServlet should retrieve ServletServerInvoker based on updated InvokerLocator ------------------------------------------------------------------------------------------------------------- Key: JBREM-981 URL: http://jira.jboss.com/jira/browse/JBREM-981 Project: JBoss Remoting Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 2.4.0.CR2 Reporter: Ron Sigal Assigned To: Ron Sigal Fix For: 2.4.0.GA >From Galder: Consider <servlet> <servlet-name>Ejb3ServerInvokerServlet</servlet-name> <description>The ServerInvokerServlet receives requests via HTTP protocol from within a web container and passes it onto the ServletServerInvoker for processing. </description> <servlet-class>org.jboss.remoting.transport.servlet.web.ServerInvokerServlet</servlet-class> <init-param> <param-name>locatorUrl</param-name> <param-value>servlet://${jboss.bind.address}:8080/unified-invoker/Ejb3ServerInvokerServlet</param-value> <description>The servlet server invoker</description> </init-param> <load-on-startup>1</load-on-startup> </servlet> Now, let's say you bind to 0.0.0.0. You'll get an exception like this: 13:39:26,856 ERROR [ContainerBase] Servlet /unified-invoker threw load() exception javax.servlet.ServletException: Can not find servlet server invoker with same locator as specified (servlet://0.0.0.0:8080/unified-invoker/Ejb3ServerInvokerServlet) at org.jboss.remoting.transport.servlet.web.ServerInvokerServlet.getInvokerFromInvokerUrl(ServerInvokerServlet.java:198) at org.jboss.remoting.transport.servlet.web.ServerInvokerServlet.init(ServerInvokerServlet.java:66) The problem arises from the fact that Remoting is trying to compare: servlet://0.0.0.0:8080/unified-invoker/Ejb3ServerInvokerServlet with servlet://localhost.localdomain:8080/unified-invoker/Ejb3ServerInvokerServlet So either, ServerInvokerServlet should call ServerInvoker.validateLocator() with locatorUrl, take the return of that and compare that with the list of locators. Or validateLocator() is modified to have the real original host passed to the InvokerLocator constructor, rather than the transformed or newHost. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBREM-1229) Display recreated InvokerLocator when bind address is 0.0.0.0

by Ron Sigal (JIRA)

Display recreated InvokerLocator when bind address is 0.0.0.0 ------------------------------------------------------------- Key: JBREM-1229 URL: https://jira.jboss.org/browse/JBREM-1229 Project: JBoss Remoting Issue Type: Task Security Level: Public (Everyone can see) Affects Versions: 2.5.2.SP3 (Flounder), 2.2.3.SP2 Reporter: Ron Sigal Assignee: Ron Sigal Priority: Minor Fix For: 2.2.3.SP3, 2.5.2.SP4 (Flounder) Occasionally, the character "_" is used in hostnames, which is illegal, according to http://www.ietf.org/rfc/rfc952.txt. The java.net.URI parser gets confused, and the detectable phenomenon is the replacement of the port with -1. When 0.0.0.0 is given as the bind address, org.jboss.remoting.ServerInvoker calls org.jboss.Remoting.InvokerLocator.validateLocator() to create an InvokerLocator with a host accessible over a network. By default, the host name is used, which leads to the problem described above. If the system property InvokerLocator.BIND_BY_HOST (actual value "remoting.bind_by_host"), the host address will be used instead, which would work around the problem. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Resolved: (JBREM-827) Define a management interface for JBoss Remoting

by Trustin Lee (JIRA)

[ https://jira.jboss.org/browse/JBREM-827?page=com.atlassian.jira.plugin.sy... ] Trustin Lee resolved JBREM-827. ------------------------------- Resolution: Done Javadoc has been checked in. Also, Endpoint.getRequestCounters() has been separated into the two versions. One is for inbound requests and the other is for outbound requests. To avoid possible confusion, I also renamed getRequestCounters() in ConnectionMXBean and ServiceMXBean to getOutboundRequestCounters() and getInboundRequestCounters() respectively. http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jbossremoting?view=revision&re... > Define a management interface for JBoss Remoting > ------------------------------------------------ > > Key: JBREM-827 > URL: https://jira.jboss.org/browse/JBREM-827 > Project: JBoss Remoting > Issue Type: Task > Security Level: Public(Everyone can see) > Components: r3 core > Reporter: David Lloyd > Assignee: Trustin Lee > Fix For: 3.1.0.Beta3 > > -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
