Subject [jira] Commented: (DERBY-2017) Client driver can insert and commit partial data when a LOB stream throws IOException or does not match the specified length
Date Mon, 29 Mar 2010 10:08:27 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2017?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12850868#action_12850868
] 

Knut Anders Hatlen commented on DERBY-2017:
-------------------------------------------

Thanks, Kristian. The new patch looks fine to me. My only further comments are (I don't think
you need to hold the commit, though):

1) New error messages in EXTDTAReaderInputStream.getStatus()/checkStatus() and FailingEXTDTAInputStream.read()
are not internationalized.

2) Could the two JUnit tests for this issue also be enabled now?

By the way, I noticed that the layer B test ran in just 6 seconds on my laptop, whereas the
layer A test needed 2 minutes to complete. I haven't studied the details of the tests, but
perhaps you could tell if this difference is expected?

> When a LOB stream throws an exception or does not match the specified length, the client
driver does not raise an exception until it has finished executing the statement. Therefore,
the statement will be executed (and possibly committed) on the server even though the client
reports that the statement failed.
