Hi All,

I have a problem with backing up firebird database. I have posted regarding
this a couple of times. At the end of this post is a test case that when run
against jaybird from the latest CVS will produce a database that cannot be
backed up. It fails with the following error:

gbak: ERROR: segment buffer length shorter than expected
gbak: ERROR: gds_$get_segment failed
gbak: Exiting before completion due to errors

I find this problem quite frustrating - In my opinion if the server allows a
database to be created and filled in in a particular way without error -
sureley it should then be able to back up the database ! So in my opinion
this should be considered a bug somewhere in Firebird.

The main difference between Jaybird 1.0.1 and Jaybird CVS HEAD is that
jaybird CVS HEAD makes use of streamed blobs and Jaybird 1.0.1 makes use of
segmented blobs.

A simple piece of java code that can create a database that cannot be backed
up is at the end of this post. This needs to be run against Jaybird CVS HEAD
to reproduce the problem. I can supply binaries of this Jaybird version if
this will help anyone - or I can supply the database produced. I can explain
and supply code snippets showing how Jaybird CVS HEAD is using the Firebird
API to create the blob.

Any infomation, clues or help would be very much appreciated. Maybe I am
just overlooking somthing obvious in which case I appologise.

Thanks
Ryan
