Subject [jira] Commented: (ZOOKEEPER-17) zookeeper_init doc needs clarification
Date Wed, 01 Oct 2008 07:23:44 GMT

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-17?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12635964#action_12635964

Austin Shoemaker commented on ZOOKEEPER-17:

The documentation states that if the client_id given to zookeeper_init is expired or invalid
that a new session will be automatically generated, implying that it will proceed to the CONNECTED

In the implementation an expired or invalid client_id leads to the unrecoverable SESSION_EXPIRED_STATE,
which requires closing and reopening a new connection with no client_id specified to continue.

Since the server has already assigned a replacement client_id it seems logical to follow the
header documentation and proceed with the new value, which appears to be possible by removing
the if-block that triggers the expired state in check_events (zookeeper.c).

If the client application needs to know if the session was replaced, it can simply compare
the client_id it provided with the client_id upon entering CONNECTED_STATE.

What do you think?
