ejabberd 2.0.0 beta 1
|
|
24 december 2007
|
|
|
|
ejabberd 2.0.0 is a major new version for ejabberd adding plenty of
|
|
new features, performance and scalability improvements and
|
|
architectural changes.
|
|
|
|
ejabberd 2.0.0 includes near that 200 improvements over ejabberd
|
|
1.1.x. A complete list of changes can be retrieved from:
|
|
http://redir.process-one.net/ejabberd-2.0.0
|
|
|
|
The new code can be downloaded from ejabberd download page:

|
|
|
|
|
|
Recent changes include:
|
|
|
|
|
|
* Clustering and Architecture
|
|
|
|
- New front-end and back-end cluster architecture for better
|
|
scalability and robustness. Back-end nodes are able to run a fully
|
|
fault-tolerant XMPP router and services, but you can now deploy
|
|
many front-end nodes to share the load without needing to synchronize
|
|
any state with the back-ends.
|
|
- All components now run in cluster mode (For example, Multi-User chat
|
|
service and file transfer proxy).
|
|
- New load balancing algorithm to support Multi-User chat and gateways
|
|
clustering. More generally it supports any external component load
|
|
balancing.
|
|
- ejabberd watchdog to receive warning on suspicious resources consumption.
|
|
- Traffic shapers are now supported on components. This protect
|
|
ejabberd from components and gateways abuses.
|
|
|
|
|
|
* Publish and Subscribe
|
|
|
|
- Complete rewrite of the PubSub module. The new PubSub module is
|
|
plugin-based, allowing developers to create new nodes type. Any
|
|
application can be plugged to ejabberd and can provide rich presence
|
|
as a pubsub plugin.
|
|
- Personal Eventing via Pubsub support (XEP-0163). This module is
|
|
implemented as a PubSub service. It supports user mood (XEP-107),
|
|
User Tune (XEP-118), user location (XEP-0080) or user avatar
|
|
(XEP-0084) for example.
|
|
|
|
|
|
* Server to Server (s2s)
|
|
|
|
- More robust code with connection timeout implementation.
|
|
- Support for multiple s2s connections per domain.
|
|
- s2s whitelist and blacklist support.
|
|
- s2s retrial interval.
|
|
|
|
|
|
* LDAP
|
|
|
|
- Many enterprise-class enhancements such as better behaviour under
|
|
heavy load.
|
|
- Support for LDAP servers pool.
|
|
- Simplified use of virtual hosting with LDAP with domain substitution
|
|
in config.
|
|
- Ability to match on several userid attibutes.
|
|
|
|
|
|
* Multi-user chat
|
|
|
|
- Clustering and load balancing support.
|
|
- Ability to define default room configuration in ejabberd config file.
|
|
- Many anti abuse features have been added:
|
|
. New ACL to limit the creation of persistent room to autorized users.
|
|
. Ability to define the maximum number of users per room.
|
|
. Limitation of the rate of message and presence packets.
|
|
. Limitation of the maximum number of room a user can join at the same time.
|
|
|
|
|
|
* File transfer
|
|
|
|
- XEP-0065 - Proxy65 file transfer proxy. The proxy can run in
|
|
cluster mode.
|
|
|
|
|
|
* Authentication
|
|
|
|
- PAM (Pluggable Authentication Modules) support on *nix systems.
|
|
- External Authentication protocol is now fully documented.
|
|
|
|
|
|
* Web client support
|
|
|
|
- XEP-0124 - BOSH support: BOSH (Bidirectional-streams Over
|
|
Synchronous HTTP) was formerly known as "HTTP binding". It provides
|
|
an efficient alternative to HTTP polling for scalable Web based chat
|
|
solutions.
|
|
- HTTP module can now serve static documents (with
|
|
mod_http_fileserver). It is needed for high-performance Web2.0 chat
|
|
/ IM application. System administrators can now avoid using a proxy
|
|
(like Apache) that handles much less simultaneous than ejabberd HTTP
|
|
module.
|
|
- Added limitations enforcement on HTTP poll and HTTP bind modules
|
|
(bandwidth, packet size).
|
|
|
|
|
|
* System administration
|
|
|
|
- XEP-0133 - Service administration support. System administrators can
|
|
now performs lot of ejabberd related admin tasks from their XMPP
|
|
client, through adhoc commands.
|
|
- Dynamic log levels: Improved logging with more log levels. You can
|
|
now change the loglevel at run time. No performance penality is
|
|
involved when
|
|
- Better command-line tool, with more options available.
|
|
|
|
|
|

|
|

|
|
Dutch, English, French, German, Spanish, Russian.
|
|
- Makefile now implements uninstall command
|
|

|
|
- Configure script is clever at finding libraries in unusual places.
|
|
|
|
|
|
* Development API

|
|
presence related hooks).
