Divmod Axiom is an object-relational database backed by SQLite, the goal of which is to provide an efficient, non-SQL interface to an existing relational database manager. It provides support for common Twisted practices: an Axiom store is also a Twisted IServiceCollection provider, and an implementation of Twisted's IRealm interface is provided. It makes heavy use of plugins and includes a wall-clock scheduler.
Epsilon is a small utility package. Its dependencies make it inappropriate for inclusion in Twisted, but it performs functions that are generic enough to be used in projects that don't want to share the large footprint of Divmod's other projects. Currently, it includes a powerful date/time formatting and import/export class for exchanging date and time information between all Python's various ways to interpret objects as times or time deltas. It also includes some tools for managing concurrent asynchronous processes within Twisted.
Mantissa is an application server. It provides integration between the Axiom object database and the Twisted framework, as well as Web user-interface utilities. Mantissa is the deployment target: it can serve an application over several protocols; HTTP is one of those protocols, but HTTP isn't treated specially by the software.
Nevow is a Web application construction kit. It is designed to allow the programmer to express as much of the view logic as desired in Python, and includes a pure Python XML expression syntax, named stan, to facilitate this. It also provides rich support for designer-edited templates, using a very small XML attribute language to provide bi-directional template manipulation capability.
Divmod Sine is a standards-based voice-over-IP application server, built as an offering for the Mantissa application server platform. It owes much of its development to the Shtoom project, which implements a soft-phone in Python. Sine provides a SIP registrar, SIP proxy, third party call control, voicemail, and configuration through the Web based on Divmod Mantissa.
Divmod Vertex is an implementation of Q2Q, a protocol for opening authenticated connections, even through NAT. It allows a user to reliably demonstrate their identity (for distributed authentication) and receive real-time data directly from other users, and provides a mechanism for a user to decide whether they want to expose their IP address to a third party before accepting a peer-to-peer connection. It is byte-stream oriented and application-agnostic. Any peer-to-peer application can use Q2Q to open connections and deliver messages.
Pynfo is a combination IRC info, search, and network relay bot. It supports basic fact definition (with persistence between runs) and searching of Google and Dict.org. In the network relay mode it "bridges" channels on different networks by passing messages between them. It also has a plugin interface, allowing users to easily define new commands.
Conch is an SSHv2, Telnet, and VT102 implementation. It interfaces well with other Python projects such as Imagination, and includes an experimental console windowing library (Insults) and support for rudimentary line editing behaviors. A new implementation of Twisted's Manhole application is also included, featuring server-side input history and interactive syntax coloring.
Twisted Mail provides client and server implementations of SMTP, POP3, and IMAP4. These differentiate themselves from the Python standard library implementations both by presenting a much higher-level, easy-to-use interface and in their server components, which allow the implementation of custom servers for each protocol without dealing with protocol-level issues. Twisted Mail includes a simple demonstration email server which accepts messages over SMTP, stores them in a Maildir arrangement, and can serve them to clients over POP3.
