With the release of 1.1.0, this now frees us to start looking at what should start going into version 1.2. A number of activities have been awaiting this: 1. Known enhancements where concrete changes are forthcoming: a) Rotating between sl_log_1 and sl_log_2 b) Improving performance of COPY_SET by dropping/recreating indices c) Win32 support d) Major revision to test suite 2. Plausible Changes (if we can come up with strategies/time): a) Reduce numbers of redundant changes submitted in sl_seqlog b) Reduce numbers of pg_listener entries that need to be destroyed c) Migrate documentation from DocBook/SGML to DocBook/XML d) Invalidate cached SPI plans so that when Slony-I is deinstalled from a node, queries don't fail due to pointing to the now-invalid query plans e) Separate fetch/put into their own threads so updates (on subscriber) can be concurrent with the fetchs (on provider) 3. Migrate to pgFoundry Which offers a fair bit more functionality than GBorg... This might include such things as: - Moving from CVS to Subversion (if possible; it's not clear how supported Subversion is at pgFoundry at this time) - Separating out some of the components to separate repositories (e.g. - the "Admin Guide" isn't really part of the replication engine, so we almost certainl shouldn't pretend that it is...) Likely repositories would include: a) 'minimal' "replication engine" repository b) Admin guide c) Perhaps multiple repositories for different groups of tools/scripts including: - 'altperl' - Log Shipping samples/helpers - Maintenance jobs (e.g. - generate_syncs.sh) - Monitoring scripts These are presently somewhat jumbled together... There already is a Slony-I project at pgFoundry.org; it is likely that the migration will take place over the span of at least a month, so that things are thought through, and done coherently. Supposing we could accomplish merely the items in 1) and 3) between now and (say) September, that would provide a quite compelling 1.2 release, as those changes should lead to a quite appreciable improvement in performance, combined with the addition of Windows support. In the short term, by all means, please continue to report bugs and requests for features at GBorg <http://gborg.postgresql.org/project/slony1/>. Those that hang out on IRC should consider the above a pretty fair "target for discussion." :-). I'm sure this quasi-plan will change somewhat when others get to react to it!
