Subject [jira] Updated: (ZOOKEEPER-220) programming guide watches section should clarify server/clientlib role in data/child watch maint.
Date Mon, 02 Feb 2009 22:15:59 GMT

     [ https://issues.apache.org/jira/browse/ZOOKEEPER-220?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Benjamin Reed updated ZOOKEEPER-220:
------------------------------------

    Attachment: ZOOKEEPER-220.patch

This patch makes some minor clarifications to that section. conceptually it is very helpful
to think of two lists of watchers, so i don't think it would be wise to remove it. (internally
it is actually a bit more complicated.) i added a bit more wording to appeal to the intuition.

the server, esp as in v3 the client is also maintaining it's own list(s).
