[jbossts-issues] [JBoss JIRA] Commented: (JBTM-653) refactor Xid handling

[Mark Little (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBTM-653?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12494592#action_12494592 ] 

Mark Little commented on JBTM-653:
----------------------------------

The reason basic Xid handling was in ArjunaCore was due to recovery. With the exception of the node identifier, which was introduced specifically for XA recovery, all of the other XA specific needs for recovery were moved elsewhere over the years. I see all of what remained has been moved, but the docs remained talking about XA. However, by some suitable modifications to the docs as well as the prospect of the related JIRA, it's possible to make it a clean break.

> Xid handling is a horrible mess. Creation is excruciatingly slow because XATxConverter uses Uid.stringFrom, then promptly turns the string back into a bunch of bytes. XID has no business being in ArjunaCore, or indeed externally exposed at all - it should be internal to XidImple.  Some static utility methods on XATxConverter and elsewhere would be better off in XidImple too.
