= Features =
* londiste: Wait commands
> londiste $ini add-table .. --wait-sync
> londiste $ini wait-sync
Wait until all tables are fully copied over.
> londiste $ini wait-root
Wait for next tick on root reaches local node.
> londiste $ini wait-provider
Wait for next tick on provider reaches local node.
* londiste execute: support meta attributes in sql
This allows execute ADD COLUMN from root, over whole
cascade even when not all nodes contain the table.
--*-- Local-Table: mytable
ALTER TABLE mytable ADD COLUMN foo text;
* Convert DB modules to extensions (9.1+). Now following modules
are available as extensions: pgq, pgq_node, pgq_coop, pgq_ext, londiste.
All the old files are kept in old locations to avoid any breakage.
Known problems in Postgres extensions infrastructure (as of 9.1.4):
- pg_dump crashes when extensions has sequence whose value needs to be dumped.
Thus pgq.batch_id_seq cannot be made dumpable, thus it's value
gets lost during dump+reload.
- CREATE EXTENSION pgq_coop FROM unpackaged; + DROP EXTENSION pgq_coop;
will not drop schema. Plain CREATE+DROP works fine.
= Minor Features =
* londiste.applied_execute: drop queue_name from pkey
* pgq.LocalConsumer: consumer that tracks processed ticks in local file
* simple_local_consumer: LocalConsumer that runs query for each event.
* pgq.Consumer: 'table_filter' config param, filters on ev_extra1,
where PgQ triggers put source table name.
* londiste.periodic_maintenance: cleanup for applied_execute
* pgq.maint_operations: include londiste.periodic_maintenance
* skytools.exists_view(): new function
* skytools.fileutil: new module, contains write_atomic()
* londiste.handler: make encoding= param available to part & londiste handlers
* debian: build modules for all installed server-dev versions
= Fixes =
* CascadedConsumer: re-initialize provider connection when location changes
* pgq_node.drop_node: mention node name in info message
* drop-node: move find_root before local drop
* pgq.maint_rotate_tables: check txid sanity, fail if bad
* sql_tokenizer: allow idents starting with underscore
* BaseScript: write pidfile atomically to avoid corrupt pidfiles.
* londiste replay: skip provider checks if copy_node is used
* CascadedWorker: don't move watermark on source further than incoming batch.
