[ https://jira.jboss.org/browse/ISPN-731?page=com.atlassian.jira.plugin.sys... ] Mircea Markus updated ISPN-731: ------------------------------- Summary: make rehashing state and tx log draining serial (was: make state transfer and tx log draining serial) Description: {A,B,C, D}, num owners= 2. A's state is {(k,v)} and a transactions is prepared with {(k, otherValue)} on A. B crashes. two things happen with A's state: 1. on C an thread pulls state from A 2. A sends transaction state to C on another thread Whit the right timing: - 2 executes first (tx log is drained) - tx commits - this applies the changes on C as well - 1 executes last Data ends up inconsistent: A's states is {(k, otherValue)} while C's state is {(k,v)} State transfer and tx log needs to be sequential (not parallel). See the attached email thread for discussions around this. was: {A,B,C, D}, num owners= 2. A's state is {(k,v)} and a transactions is prepared with {(k, otherValue)} on A.

The easy way to achieve this is to only do push, i.e. A sends the state and then drains tx log. This can be reproduce by running ConcurrentNonOverlappingLeaveTest.testTransactional (fails aprox 1/5) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
