Andy Seaborne commented on JENA-163:
------------------------------------
Even when the multiple file open issue is fixed, there is still a problem - it
occurs (typically) after a longer run.
The current Jena163_TDBDifferentIds prints out every file open/sync/close on
the journalled files so I check that the right sequence of file operations and
ownership is happening. Therefore, it might be that file operations from
different threads do not provide the necessary guarantees of consistency. This
is fixable by simply initializing the state of the file when it is started to
be used, rather than when it is finished with. When this is done, the test
case runs for much longer. Other, unrelated problems sometimes occur but on
checking all these, they are not connected with file management.
Next step: central file management (avoids repeated open/close), initialize the
state of a temporary journal file explicitly at point of use. These will
affect,positively, the test case and are generally better design anyway.
