Overview of the Repoze Project

Problems Addressed

Some of the things that Zope does are useful enough to be applicable to non-Zope-based WSGI applications: transaction management, virtual hosting, form marshalling, declarative access control, etc. But currently it's not easy for Python web developers who aren't fluent in Zope to make use of these features, because they aren't always decomposed into individually reusable pieces.

At the same time, WSGI deployment of Python applications has become a defacto standard in the wider Python world. At the time of the project's inception, it was reasonably difficult to serve up Zope (particularly Zope 2) via a WSGI server.

Note

The current release line (2.13.x) of Zope2 has landed changes originally made here to support WSGI natively.

Solutions Provided

The Repoze project provides components which reimplement core Zope features as WSGI middleware (repoze.vhm, repoze.retry, repoze.tm2), and WSGI applications (repoze.zope2, repoze.grok). The Repoze project also reuses existing WSGI middleware (Paste) and servers where possible.

The bits of Repoze that reimplement core Zope features can be ignored or used as necessary in non-Zope contexts.

Software Requirements and Limitations

  • The packages in the repoze. namespace require setuptools for installation.
  • None of the repoze.* software has been tested under any version of Windows. It has only been tested under UNIX variants (Linux and Mac OS X at the time of this writing).

Technology Dependencies

Many Repoze components depend on Paste, as well as setuptools and the WSGI specification. Repoze reimplements and reuses some technologies originated within Zope.

Licensing

The original bits that make up Repoze are released under a BSD-style license.

Some non-original parts of Repoze are licensed under the ZPL (another BSD-style license).

Legacy Resources

Note

Currently-maintained packages have their repositories on Github under the repoze organiztion.

Note

Currently-maintained packages have their issue trackers located with their repositories on Github.

Note

The packages on dist.repoze.org were added to deal with some no-longer-relevant issues on the PyPI index. They are no longer being updated.
