[JCBC-276] Client does not detect silently dying Streaming Node

Mon, 20 May 2013 14:30:42 -0500

When connected to the EPT/streaming node and the node is "frozen" or dies silently otherwise (doesn't force the closing of the chunked socket), the connection stays established.

This can easily be reproduced outside of the client by connecting the browser to the streaming URL and then freezing a VM. The browser will still "spin" and wait for new chunks to come up.

The proposed solution is to have a netty handler in place that raises a exception when there is not traffic for N number of seconds (like 30) over the streaming connection. After this is detected, we have two possibilities:

- reconnect completely, but this involves lots of overhead every 30 seconds.
- send a HTTP HEAD packet and only if this doesnt work out reconnect. This means in the normal case we only have a HTTP HEAD request sent every 30 seconds, not much overhead.
If this fails, we then trigger the reconfigure.

Netty has a ReadTimeoutHandler to help with this. My POC already kinda works, I just need to find a way to properly distinguish the HEAD response on the ResponseHandler from regular chunks that arrive from the same channel.

[JCBC-229] Find a way to proper test JCBC-227

Dependency — Mon, 25 Feb 2013 05:12:00 -0600

The issue fixed in jcbc-227 needs proper testing. Can you please add tests for this either as a unit test, or integrate it into sdkd? I'm not sure where it fits - what do you think?

[JCBC-303] javadoc builds must include spymemcached

Duplicate — Wed, 15 May 2013 11:21:36 -0500

Current javadoc build process does not include the spymemcached docs, which were included in previous releases. The documentation:

http://hub.internal.couchbase.com/confluence/display/techpubs/Using+Existing+Docs+System+%28WIP%29

does not mention how to include, nor is there evidence of how it was done before.

Need to have:

* a process that includes correct third-party documentation, when required.

* one that is not tied to a particular host

* is fully documented

[JCBC-189] Views having odd timeout issues on some clusters

Dependency — Mon, 20 May 2013 14:30:46 -0500

We're seeing really strange timeout issues which seem to affect only this specific cluster and only in terms of views. We've re-installed this cluster time and time again, and we've had similar configurations run successfully as well.

More details in comment..

[JCBC-244] Sample Application : fix the welcome file and gitignore

Thu, 2 May 2013 16:33:23 -0500

1- the Welcome auto redirect in Jetty does not work correctly.
2- Update the gitignore to handle IDE and OS

[JCBC-161] Remove Duplication in Observe checks

Mon, 20 May 2013 14:30:47 -0500

The fix for ~~JCBC-148~~ works, but it checks against all nodes in the cluster. If you have a larger cluster, you have much more nodes than there could be assigned to a specific key. As an enhancement, the code in checkConfigAgainstPersistence should check against the nodes for the given key, not for everything.
