Archiveopteryx 3.0.0
3.0.0 was released on on 2008-08-25.
This is a feature release and we expect to release 3.0.1 soon. The new features in 3.0.0 include:
- aox has command-line searches; show search helps construct searches, aox undelete and aox add view use searches.
- aox add alias etc. has more friendly syntax (higher dwim factor).
- Bodyparts can have the same MD5 hash.
- Full-text search is available. Needs PostgreSQL 8.3 and the new command aox tune database.
- Memory usage is configurable (memory-limit=32); bigger numbers imply more caching.
- Message rejection is now configurable using soft-bounce.
- The tables can be put in any schema, not just public.
- SQL listen/notify used instead of the ocd.
- aox shutdown includes a two-second pause, is more polite to clients, and handles the race condition described in RFC 1047.
- The message injector can inject several messages at a time, speeding up aoximport and other things.
- Client usage is logged using the connections log table.
- Syslog support added (note: syslog has limited line length).
- Less logging by default.
- SASL DIGEST-MD5 disabled by default due to widespread interoperability problems.
- Sieve ereject support added.
- check-sender-addresses allows/disallows forged From on outgoing mail.
The bugfixes in 2.11 are also in this release. In addition there are some unremarkable changes:
- Various SQL improvements: More set logic (=any(…)) instead of boolean logic, more use of savepoints.
- Various IMAP optimisations (store, status, select, fetch).
- The pool of database connections is managed more cleverly.
- aox grant privileges uses clearer queries, and aox upgrade schema checks/fixes privileges.
- Some support for old (>2 years) databases removed.
- Support for >2GB logfiles added.
- Magic hacks to avoid queries that bother PostgreSQL 8.1.
- HTTP-related changes, still not conclusive.
- IMAP VIEW command removed, views remain supported.
- IMAP commands finish in order (even if executed concurrently).
- Fetch responses are sent at regular pace, to avoid timing out clients.
- IMAP Search has been cleaned up for reuse (likely release in 3.1).
- A couple of message parsing improvements that were hard to do in 2.11.
- The privileges needed for each table are explicitly marked in the CREATE TABLE statements.
- We have our first-ever unintentionally undocumented feature.
- Compile fixes for new warnings in g++ 4.3.
Downloading:
- Source code in .tar.bz2 format, 2.5MB.
If you are upgrading from 2.x, please run "aox stop" before you install the new release (because the location of the pid files has changed, so the new aox won't be able to stop the running server).
The 2.11 bugfix release uses a database that is compatible with this release, so if you upgrade from 2.x to 3.0.0 and encounter problems, you can fall back safely to 2.11.
Although we support PostgreSQL 8.1.x, we strongly recommend that you upgrade to PostgreSQL 8.3 to get better performance from this release.
The next 3.0.x bugfix release is 3.0.1. We have not decided on a release date yet.
