**Paste has entered life support mode and will henceforth be maintained
from https://github.com/cdent/paste .**
Paste provides several pieces of "middleware" (or filters) that can be nested
to build web applications. Each piece of middleware uses the WSGI (`PEP 333`_)
interface, and should be compatible with other middleware based on those
interfaces.
.. _PEP 333: http://www.python.org/dev/peps/pep-0333.html
* `Paste project at Bitbucket (source code, bug tracker)
<https://bitbucket.org/ianb/paste/>`_
* `Paste on the Python Cheeseshop (PyPI)
<https://pypi.python.org/pypi/Paste>`_
* `Paste documentation
<http://pythonpaste.org/>`_
See also:
* `PasteDeploy <http://pythonpaste.org/deploy/>`_
* `PasteScript <http://pythonpaste.org/script/>`_
* `WebTest <http://webtest.pythonpaste.org/>`_
* `WebOb <http://docs.webob.org/>`_
Includes these features...
Testing
-------
* A fixture for testing WSGI applications conveniently and in-process,
in ``paste.fixture``
* A fixture for testing command-line applications, also in
``paste.fixture``
* Check components for WSGI-compliance in ``paste.lint``
Dispatching
-----------
* Chain and cascade WSGI applications (returning the first non-error
response) in ``paste.cascade``
* Dispatch to several WSGI applications based on URL prefixes, in
``paste.urlmap``
* Allow applications to make subrequests and forward requests
internally, in ``paste.recursive``
Web Application
---------------
* Run CGI programs as WSGI applications in ``paste.cgiapp``
* Traverse files and load WSGI applications from ``.py`` files (or
static files), in ``paste.urlparser``
* Serve static directories of files, also in ``paste.urlparser``; also
in that module serving from Egg resources using ``pkg_resources``.
Tools
-----
* Catch HTTP-related exceptions (e.g., ``HTTPNotFound``) and turn them
into proper responses in ``paste.httpexceptions``
* Several authentication techniques, including HTTP (Basic and
Digest), signed cookies, and CAS single-signon, in the
``paste.auth`` package.
* Create sessions in ``paste.session`` and ``paste.flup_session``
* Gzip responses in ``paste.gzip``
* A wide variety of routines for manipulating WSGI requests and
producing responses, in ``paste.request``, ``paste.response`` and
``paste.wsgilib``
Debugging Filters
-----------------
* Catch (optionally email) errors with extended tracebacks (using
Zope/ZPT conventions) in ``paste.exceptions``
* Catch errors presenting a `cgitb
<http://docs.python.org/2/library/cgitb.html>`_-based
output, in ``paste.cgitb_catcher``.
* Profile each request and append profiling information to the HTML,
in ``paste.debug.profile``
* Capture ``print`` output and present it in the browser for
debugging, in ``paste.debug.prints``
* Validate all HTML output from applications using the `WDG Validator
<http://www.htmlhelp.com/tools/validator/>`_, appending any errors
or warnings to the page, in ``paste.debug.wdg_validator``
Other Tools
-----------
* A file monitor to allow restarting the server when files have been
updated (for automatic restarting when editing code) in
``paste.reloader``
* A class for generating and traversing URLs, and creating associated
HTML code, in ``paste.url``
The official development repo is at https://bitbucket.org/ianb/paste.
