Обсуждение: JDBC buggy in 7.1beta3
I reported a JDBC bug in the 7.1 beta1 release back in December and notice that the same bug is still present in the currentbeta 3 sources. The problem relates to nested cursors failing and is quite simple to reproduce. A simple test casecan be found at: http://www.twospuds.com/pg7-1b3-jdbc-bug.tar.gz The 7.0.2 JDBC drivers work fine against the 7.1b3 backend, with a little tweaking for "long" rows. Peter (Mount) did acknowledge the bug but I have not heard anything on the list since then. Is anyone looking at it? Cometo think of it, I haven't seen anything on the lists [HACKERS mainly] from Peter for a while.

Is anyone looking at it? Come to think of it, I As I've said numerous times on lists and direct to people, I've had several major problems which have hampered things since November, but I am now slowly catching up. The problems have been: * 2 SCSI discs dying on my linux box 2 weeks ago * changing ISP's (now resolved) * Changing jobs, which mean I have to limit how much time I can spend at the moment. * UK Dialup has been horrendous this last week Now, my linux box is up and running, but no networking. Due to my job Thursday evenings are out now (learning German), so I can't finish of its rebuild before Saturday. This is holding things up because I don't have a 7.1 backend to test against (& I can't get it to build under NT yet either). So while she's down, I've been doing other things that either don't need a backend to test, or (in the case of the XML stuff) test against Oracle. What may be of use, is for people to email me again with any known bugs, so I can compile a list of what needs to be done before 7.1, or what has already been done/obsoleted or re-written from scratch. This weekend I'm planning on: Sat am: finish rebuild of linux box Sat pm: test current cvs against current 7.1beta Sun am: catch up with bug list Sun pm: If time, move over more stuff into contrib Peter -- Peter Mount peter@retep.org.uk PostgreSQL JDBC Driver: http://www.retep.org.uk/postgres/ RetepPDF PDF library for Java: http://www.retep.org.uk/pdf/

This is no longer a problem in 7.1. The bug here was the same one introduced by the wrong version of Gunner's bytearray pooling patch being applied. It was fixed in current sources by Peter commenting out the bytearray pooling. thanks, --Barry Bruce Momjian wrote: > > Anyone fixing this bug? > > > I reported a JDBC bug in the 7.1 beta1 release back in December and notice that the same bug is still present in thecurrent beta 3 sources.
