slices does can not work with sequences properly (no adding objects?)
---------------------------------------------------------------------
Key: OPENJPA-798
URL: https://issues.apache.org/jira/browse/OPENJPA-798
Project: OpenJPA
Issue Type: Bug
Components: kernel
Affects Versions: 2.0.0
Reporter: Fernando
Priority: Critical
I can't believe that this was a bug that was existent.. but essentially once I
got slices fixed up (see many preceding bugs), it all seems to work fine,
except for I can't persist new objects. Essentially the DistributedResultSet
is very very buggy, and not implemented properly, so TableJDBCSeq can't do it's
job properly ( since it's using the
DistributedConnection/PreparedStatement/RestulSet ).
I just wanted to file the bug to get the word out.. but I basically have to
re-write the whole class, So I guess I'll be submitting a patch tomorrow.
The first bug is that it will drop out the first row from every ResultSet (one
per db). It does this because as ResultSets are added, it calls "first", but
then most people (and TableJDBCSeq), assume that it's "beforeFirst", so they
call "next" expecting it to move to "first". So in TableJDBCSeq, it goes
beyond the first row, returning null.. and TableJDBCSeq thinks that the query
actually returned an empty RestultSet and tries to act accordingly...
and as you review DistributedResultSet, you see lots and lots of bad logic,
missing code, etc. It's a pretty hacked together implementation of a
"Distributed ResultSet".... need a proper version..
