* QPID-3438Michael Goulish2012-01-051-2/+0
| | | | | | | | | | Remove unnecessary changes to broker. The cluster code does not really need to know that the cnx error was due to auth failure. Any failure before the cnx has opened should cause the cnx to be removed from the 'local' map, or a cnx leak will occur. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@1227616 13f79535-47bb-0310-9956-ffa450edef68

* Bug 730017, QPID-3475: Cluster authentication ignores cluster-* settings.Alan Conway2011-09-071-1/+3
| | | | | | | | | When a broker joins a cluster, it should be authenticated authenticate using the options --cluster-username, --cluster-password and --cluster-mechanism. The broker was ignoring the settings and joining the cluster even if an invalid user or password are supplied. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@1166279 13f79535-47bb-0310-9956-ffa450edef68
* NO-JIRA: Suppress logging of clock events in cluster code.Alan Conway2011-08-311-1/+1
| | | | | | | Clock events are much too frequent to log, doing so makes trace logging useless for clustered brokers. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@1163766 13f79535-47bb-0310-9956-ffa450edef68

* QPID-3280: Performance problem with TTL messages.Alan Conway2011-06-151-4/+11
| | | | | | | | | | | | When sending a large number of messages with nonzero TTLs to a cluster, overall message throughput drops by around 20-30% compared to messages with TTL 0. The previous approach to TTL in the cluster is replaced with a simpler "cluster clock". Also QueueCleaner is executed in the cluster timer, and modified to be deterministic in a cluster. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@1136170 13f79535-47bb-0310-9956-ffa450edef68

| | | | | | | | | | | This error is an assertion recently introduced in r1091097, the bug has probably been there for a while. Two fixes: - Connections that close before they are announced no longer send a deliver-close. - Fixed race in OutputInterceptor that sent a deliver-do-output after deliver-close. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@1091790 13f79535-47bb-0310-9956-ffa450edef68

| | | | | | | | | | QPID-2104: LVQ enhancement These both required some refactoring of the Queue class to allow cleaner implementation of different types of behaviour. The in-memory storage of messages is now abstracted out behind an interface specified by qpid::broker::Messages which qpid::broker::Queue uses. Different implementations of that are available for the standard FIFO queue, priority queues and LVQ (I have also separated out the 'legacy' implementation of LVQ from the new version driven by QPID-2104). git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@1069322 13f79535-47bb-0310-9956-ffa450edef68

* Defer update of managaement agent to end of update process.Alan Conway2010-12-081-2/+2
| | | | | | | | | | | Move updating of the management agent to the very end of the update process, after all objects used by the update process itself have been deleted. Before the fix deletions from the update process itself (deleting the qpid.cluster-update queue and its binding to the default exchange) were sporadically appearing as extra delete messages on the updatees management agent and causing inconsistency. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@1043621 13f79535-47bb-0310-9956-ffa450edef68
* Modified cluster_tests causes broker shut down with invalid-argument error.Alan Conway2010-12-011-20/+4
| | | | | | | | | | Described in https://bugzilla.redhat.com/show_bug.cgi?id=655078. The management agent's deleted-object list was not being replicated to new members joining the cluster, so management generated fewer deleted object notifications on the newer member, causing it to fail with an invalid-argument error. The list is now being replicated correctly. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@1041181 13f79535-47bb-0310-9956-ffa450edef68

* Cluster handle connection-negotiation phase in local broker.Alan Conway2010-06-081-117/+89
| | | | | | | | | | | | | | | | | The connection negotiation phase up to the "open" or "open-ok" frame establishes whether/what encryption to use for the rest of the connection. With this patch a cluster broker completes the initial negotiation with its local clients and only then begins multicasting to other brokers. The local broker decrypts if necessary and multicasts in the clear. This replaces a problematic locking scheme that was formerly in place which caused deadlocks. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@952692 13f79535-47bb-0310-9956-ffa450edef68

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ----------------------------------- * initial observation of a problem was a 2% failure rate in perftests of 20,000 messages against a cluster with security enabled. Problem was occasional receit of encrypted frames before the security codec had been enabled. This is fixed with locking in cluster code (no new locks in broker code) and a callback that is fired by broker::ConnectionHandler::Handler to tell the cluster code when the opening handshake has finished. This was never a problem in the non-clustered broker before because everything happened in a single thread. * the brokers that "shadow" the connection must not have null authenticators rather than real ones, so that they go through all the motions but don't do anythig. Only the directly-connected broker can perform the security handshake. * once the directly-connected broker receives the real user ID from its callback, it mcasts that ID to all other brokers. Otherwise the shadowing brokers will al think that the user ID is "anonymous". Check this by doing a substantial perftest, and using qpid-stat -c localhost:PORT to confirm that the brokers all have the same userID for the same connection. * the user ID, negotiated during the Sasl security startup, is communicated from the directly connected broker to all other cluster brokers. * If security is *not* being used, then this code should *not* tell the brokers anything about the userID -- or it will step on the value that is being set by other code pathways. * test program at cpp/src/tests/cluster_authentication_soak is not yet fully automated -- run it with something like "sudo ./cluster_authentication_soak 500" git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@944158 13f79535-47bb-0310-9956-ffa450edef68

On SSL connection where the clients certificate is authenticated (requires the --ssl-require-client-authentication option at present), the clients identity will be taken from that certificate (it will be the CN with any DCs present appended as the domain, e.g. CN=bob,DC=acme,DC=com would result in an identity of bob@acme.com). This will enable the EXTERNAL mechanism when cyrus sasl is in use. The client can still negotiate their desired mechanism. There is a new option on the ssl module (--ssl-sasl-no-dict) that allows the options on ssl connections to be restricted to those that are not vulnerable to dictionary attacks (EXTERNAL being the primary example). git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@919487 13f79535-47bb-0310-9956-ffa450edef68
