GCache is a Python module that provides a generic cache class useful for speeding up any application where objects are referenced by keys. It uses object metadata to optimize hit-rates and freshness for fetches, and uses a "write-through" mechanism for writes and deletes. It can use "if-modified-since" fetches or rsync delta updates to refresh stale cached objects. GSource classes are provided for generating useful metadata from common sources (os.stat calls and MIME headers). A simple example urlCache is implemented that supports HTTP 1.1 (rfc2616) cache-control and expire headers to ensure freshness. Also included is an rfc2616 package useful for parsing HTTP 1.1 headers, and a PCache package implementing a persistant cache using a Python shelve.
py-xmlrpc is an extremely fast implementation of the xmlrpc spec for Python (written in C). It supports both blocking and non-blocking clients and servers on Windows and POSIX platforms. Version 0.8.1 is 100% compliant with the xmlrpc validator found at http://validator.xmlrpc.com.
Pysite is a tool written in Python to generate Web sites based on the contents of files in a given directory tree. It crawls through a specified directory tree looking for files matching certain configurable patterns (like intro, title-fr, and this-is-another-page-body), building up an output Web page for each set of files found. It features valid XHTML output, support for multiple language output, simple hierarchical templates (just put a template in a directory and it will be used for all subdirectories), and basic plaintext to XHTML conversion.
The eGenix mxODBC Zope Database Adapter (Zope DA) allows you to easily connect your Zope installation to just about any database backend. Unlike Zope's ZODBC Zope DA, the mxODBC Zope DA works on Windows, Linux, and Solaris using the same interface. It implements thread-safe connection pooling and multiple physical connects per logical Zope connection. You can safely run Z SQL Methods in parallel, achieving much better performance than ZODBC Zope DA or similar database adapters under heavy load. This makes it ideal for deployment in clusters and hosting environments where stability and high performance are a priority.
HarvestMan is a multithreaded off-line browser.It has many features for customizing offline browsing through URL filters, word filters, domain filters, URL priorities, depth-fetching, fetch levels, file limits, time limits, robot exclusion protocols, and many more. It is useful to download an entire Web site or certain files from a Web site to the hard disk for offline browsing later. It supports HTTP/HTTPS and FTP protocols and can work across proxies.
Flightdeck-UI is a project that utilizes the ideas in the design of aircraft controls and instruments for creating general purpose user interfaces. The project includes Flightdeck-UI Online (a Web-based monitoring system that works entirely through the browser), the Multi-Variable Monitor (MVM) application, and a Tkinter widget library. Flightdeck-UI Online is installed on a Web server. The MVM application provides a graphical editor with theme support for quickly creating Flightdeck-UI control panels. It is possible but not necessary to write code in order to use MVM.
Xapian is a search engine library, scalable to collections containing hundreds of millions of documents. It's written in C++ with bindings for Perl, Python, PHP, Java, Tcl, C#, Ruby, and Lua. It is a highly adaptable toolkit that allows developers to easily add advanced indexing and search facilities to their own applications. It supports the Probabilistic Information Retrieval model and also a rich set of boolean query operators. Omega is a Web search application built upon the Xapian library. It can index a Web server's document tree (including HTML, PDF, OpenOffice, MS Word/Excel/Powerpoint/Works, WordPerfect, RTF, PS, etc.), or data exported from arbitrary sources (e.g. SQL databases).
