Subject [jira] Updated: (DERBY-2711) If large blob is updated after InputStream is fetched (using getBinaryStream), the stream continues to point ot old data
Date Fri, 08 Jun 2007 13:28:29 GMT

     [ https://issues.apache.org/jira/browse/DERBY-2711?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kristian Waagan updated DERBY-2711:
-----------------------------------

    Attachment: derby-2711-3a-additional.diff

'derby-2711-3a-additional.diff' must be committed on top of v2, and does the following:
 * Made variable blob final.
 * Throws exception that was caught and wrapped.
 * Added a comment that the stream will update itself and reflect the new content in all read/skip
methods.
 * Changed normal comments into JavaDoc for updateIfRequired.

In addition it removes trailing whitespace and cleans up a few JavaDoc things.

> While using a large blob (so that blob doesn't gets materialized while fetching from
database) getBinaryStream returns stream linked to dvd. After blob is is updated internally
the blob data is materialized in LOBStreamControl class but the stream continues to point
to dvd hence giving out old data.
