[JCBC-164] Support CAS for delete operation

Duplicate — Mon, 17 Jun 2013 14:19:53 -0500

It would be nice if the DELETE operation would support a CAS parameter, a feature which is available in e. g. the Ruby client library. Without the possibility for checking for a given CAS value it may happen that a DELETE removes a key-value pair which was just updated by an other thread.

Make sure reconfigure() only runs once at the same time

[JCBC-266] NPE in ConfigurationProviderHTTP needs to be handled.

Dependency — Wed, 12 Jun 2013 06:44:27 -0500

NPE in ConfigurationProviderHTTP needs to be handled.
This is seen at quite a lot of places.

Please refer to the integration test results at :

[JCBC-11] Need more unit tests for couchbase-client

Wed, 12 Jun 2013 06:43:31 -0500

        CouchbaseConnectionFactoryBuilder cfb = new CouchbaseConnectionFactoryBuilder();
        cfb.setOpTimeout(10000); // wait up to 10 seconds for an operation to succeed
        cfb.setOpQueueMaxBlockTime(5000); // wait up to 5 seconds when trying to enqueue an operation


For example, will fill up the funnel (the blocking queue) to the rim, but not overflow (immediately timeout). Once it's at the rim, it'll have to wait to wait until at least one operation flows out to add another operation. This *will* slow down the callers (their async calls will actually block on this internal queue), but that's okay in a bulk loader.

However, there are no unit tests in couchbase-client to test this.

[JCBC-18] NPE if hostnames in server bootstrap list are mixed case

Wed, 12 Jun 2013 06:43:31 -0500

A user described a scenario where using mixed case in their URIs lead to an NPE. This is from the map lookup, since what the couchbase cluster sends us is different than what the user entered, I think.

[JCBC-15] add showtype-options to documentation

Many of the Java docs should show the type in the options summary.
