Subject [jira] Commented: (JCR-631) Change resources sequence during transaction commit.
Date Fri, 15 Dec 2006 13:17:22 GMT
    [ http://issues.apache.org/jira/browse/JCR-631?page=comments#action_12458790 ] 
Jan Kuzniak commented on JCR-631:

I am afraid that it is impossible to change this sequence easily. It seems that there are
some dependencies between those managers i.e. version manager depends on state manager. Changing
this is not trivial and since this part leaks some documentation probably only author can
make it.

>                 Key: JCR-631
>                 URL: http://issues.apache.org/jira/browse/JCR-631
>             Project: Jackrabbit
>          Issue Type: Improvement
>    Affects Versions: 1.0, 1.0.1, 1.1, 0.9
>            Reporter: Przemo Pakulski
> It seems that during commmit of transaction first changes in version storage are committed,
followed by workspace changes.
> If second transaction fail it leads to situation where some nodes in workspace could
have reference (base version for example) to nonexistenst version in version storage. In such
case this node is corrupted, cannot be checked in anymore :-(.
> Long term solution is make versioning operation fully transactional (see JCR-630). In
short term I think it is worth to change sequence of commit operations on different resources
to stores changes in version storage before workspace changes.
> It would be better to have some redundant data in version storage (not referenced version)
than broken reference in workspace I think.
> Any comments ? Does it make sense ?
