Thread: Slony-I 1.0.4 Released
The Slony-I team is proud to present the 1.0.4 release of the most advanced replication solution for the most advanced Open Source Database in the world. The release tarball is available for download http://developer.postgresql.org/~wieck/slony1/download/slony1-1.0.4.tar.gz There are a limited number of "new features" this release largely in terms of adding in the ability to move or drop tables and sequences from replication: - SET DROP TABLE - drops a table from replication - SET DROP SEQUENCE - does the same for sequences - SET MOVE TABLE - moves a table from one replication set to another - SET MOVE SEQUENCE - moves a sequence from one replication set to another Other changes involve smoothing out the 'sharp edges' found by early adopters, notably including: - Frequently vacuuming pg_listener; growth of dead tuples could hurt performance - A cleanup process for pg_listener resolves cases where old slon processes may have terminated due to network problems, leaving backends around holding onto event notifications - Lowered lock level on sl_event, resolving issues where pg_dump would block Slony-I - Purges CONFIRM entries for nodes that don't exist anymore - Substantially increased documentation - More sophisticated administration scripts - Now uses string comparison for user defined types that do not have a suitable comparison operation - Safer log purging - Various other bug fixes and "improved cleanliness." - As of 1.0.4, the slon replication engine refuses to work against any database that does not have the stored procedures for the same version loaded or where the shared object containing the C language support functions and the log trigger does not match the version number. in a cluster must be upgraded at once.

Probably only with some degree of trickery. In the "1.0" series, it needs a copy of the PostgreSQL source tree. I believe it uses that to refer it to where its components should be installed. In 1.1 (in CVS HEAD), it takes some advantage of the "pgxs" support, so that you may instead point to the #includes, libs, and binaries. But that's definitely a "work in progress," as opposed to something that is complete. All I can say for certain is that getting this sort of thing to work on AIX is not fun, whatever the approach :-(. -- output = reverse("gro.gultn" "@" "enworbbc") http://www.ntlug.org/~cbbrowne/sap.html Rules of the Evil Overlord #43.

Sorry folks, the Slony-I team has produced a great product, but the project management (that's mostly me here) sucks big time! Shortly after giving Chris Browne green light for the 1.0.4 announcement we found a way to guard against bug #896. That being a really bad one I decided to stop the 1.0.4 release and go for 1.0.5 including that fix. But I failed to make sure Chris, Justin and others involved in the announcement process get the message. I have just committed those changes and 1.0.5 should be available later today. I apologize for the confusion and look forward to retire from the Slony-I project leadership position in order to fully focus on the multimaster replication project Afilias has decided to put forward.

It means that I will try to do with Slony-I what I have done successfully with several other PostgreSQL related projects - to make sure the project doesn't depend on me in person any more. None of the big items I've done (rewrite rule system, PL/pgSQL, PL/Tcl, TOAST, NUMERIC, foreign keys) really requires my attention if there's a bug. I was able to do the conceptual work and important parts of the implementation, but I didn't get stuck in/with the maintenance. I constider this a very important aspect of being a CORE developer. What I am trying to do is to spend less and less time on Slony-I and more and more time on Slony-II - the synchronous multi-master system. Slony-I was for sure one of the better things that I've done so far, but it's not going to allow early retirement with financial independance and wealth. And as long as Afilias is using Slony-I in production, Andrew Sullivan will not let me do whatever I want if there's a severe problem nobody else can fix. So don't worry, I'll be around.

Wow. First, thanks again for all your efforts, Jan. Second, I'm disappointed to hear the slony author and lead developer is leaving the slony leadership. When is that going to happen? And what does that mean with respect to your future involvement in slony?

Or someone around here will, anyway. I might get hit by a wayward
streetcar, but Afilias is very strongly committed to maintaining
and improving Slony-I even as we also sponsor work on multimaster
systems. Afilias uses PostgreSQL for almost everything we do;
for us, there is no question that we'll need to support Slony.
It's worth pointing out here that the really big database vendors
usually have more than one thing that they sell as "replication".
That's because you can't really use (for instance) RAC across a WAN.
But if you're running a bank, or network infrastructure, or a phone
company, or anything else that requires you to have plans for the
disaster recovery of your disaster recovery site, you'll certainly
need to have replicas which are geographically dispersed. That's why
we've assigned staff, aside from Jan, to keep working on Slony-I.
That's _also_ why we wanted, from the very beginning, to build a
community around Slony: we knew that we couldn't do it ourselves, if
only because our perspective is bound to be limited by our
experiences, and we wanted to make sure that we wouldn't build in
such limitations. I think we've been pretty successful in that
attempt, and I'm delighted that we've managed to attract many
really smart people to the project.

Any > chance to have a slony rpm compatible with the 7.4.5 rpm ? If someone contributes RPM packages, using the same GCC and the same RPM source RPM, then presumably it's possible. There's a BSD port, so it has proven of enough interest to attract contributions there. There's not yet a Debian package or an RPM for one or another of the RPM-based distributions; hopefully interested parties will find opportunity to build such. I can appreciate the desire to have some pre-packaged components; I generally despise the idea of compiling Perl stuff myself as that tends to turn into a system management nightmare. It may be that packages will emerge in six months; we'll see. If you need RHAT RPM packages badly enough, that may be reason to pay someone to build them. -- let name="cbbrowne" and tld="linuxfinances.info" in String.concat "@" [name;tld];; http://www.ntlug.org/~cbbrowne/linuxxian.html Y2K conversion simplified: Januark, Februark, March, April, Mak, June, Julk, August, September, October, November, December.

I'm interested in providing a Debian package, but the need to have the postgresql source tree available is a problem. At the moment, unless I incorporate slony-I into the postgresql source package, I can't package it; the Debian autobuilders cannot be configured to build one package (postgresql) and then keep its source around while another package is built. I thought someone was working on making a subsection of postgresql that would be sufficient to let packages like Slony-I build independently; is that making any progress? If not, what files from the source tree does Slony-I need for its build? I could make a binary package to provide just those and make that one a Build-dependency for the Slony-I package. -- Oliver Elphick olly@lfix.co.uk Isle of Wight http://www.lfix.co.uk/oliver GPG: 1024D/A54310EA 92C8 39E7 280E 3631 3F0E 1EC0 5664 7A2F A543 10EA ======================================== "I press toward the mark for the prize of the high calling of God in Christ Jesus."

Chris recently said on the slony lists that he's aiming to do this
for 1.1, and I have reason to believe that that'll be well on the
road to release by the end of the year. Chris, are those bits
ready? Maybe Oliver could use them as inspiration for the Debian
work?
