Involved Projects and Packages

This Python 2.4+ extension module allows you to manipulate the POSIX.1e Access Control Lists present in some OS/file-systems combinations.

This package provides a Python 3 ported version of Python 2.7's random module. It has also been back-ported to work in Python 2.6.

In Python 3, the implementation of randrange() was changed, so that even with the same seed you get different sequences in Python 2 and 3. Note that several high-level functions such as randint() and choice() use randrange().

In my testing code I heavily rely on stable random generator results and it makes porting code to Python 3 a lot harder, if all those tests have to be adjusted. This package fixes that.

Parses iCalendar and vCard files into Python data structures, decoding the relevant encodings. Also serializes vobject data structures to iCalendar, vCard, or (experimentally) hCalendar unicode strings.

The zc.lockfile package provides a basic portable implementation of interprocess locks using lock files. The purpose if not specifically to lock files, but to simply provide locks with an implementation based on file-locking primitives. Of course, these locks could be used to mediate access to other files. For example, the ZODB file storage implementation uses file locks to mediate access to file-storage database files. The database files and lock file files are separate files.

ZConfig is a configuration library intended for general use. It supports a hierarchical schema-driven configuration model that allows a schema to specify data conversion routines written in Python. ZConfig's model is very different from the model supported by the ConfigParser module found in Python's standard library, and is more suitable to configuration-intensive applications.

The Zope Object Database provides an object-oriented database for Python that provides a high-degree of transparency. Applications can take advantage of object database features with few, if any, changes to application logic. ZODB includes features such as a plugable storage interface, rich transaction support, and undo.

This package is intended to be independently reusable in any Python project. It is maintained by the Zope Toolkit project.

This package represents the core of the Zope Component Architecture. Together with the 'zope.interface' package, it provides facilities for defining, registering and looking up components.

Please see http://docs.zope.org/zope.component/ or doc package for the documentation.

The zope configuration system provides an extensible system for supporting various kinds of configurations.

It is based on the idea of configuration directives. Users of the configuration system provide configuration directives in some language that express configuration choices. The intent is that the language be pluggable. An XML language is provided by default.

Hookable object support.

Support the efficient creation of hookable objects, which are callable objects that are meant to be replaced by other callables, at least optionally.

The idea is you create a function that does some default thing and make it hookable. Later, someone can modify what it does by calling its sethook method and changing its implementation. All users of the function, including those that imported it, will see the change.

To translate any text, we must be able to discover the source domain of the text. A source domain is an identifier that identifies a project that produces program source strings. Source strings occur as literals in python programs, text in templates, and some text in XML data. The project implies a source language and an application context.

We can think of a source domain as a collection of messages and associated translation strings.

We often need to create unicode strings that will be displayed by separate views. The view cannot translate the string without knowing its source domain. A string or unicode literal carries no domain information, therefore we use messages. Messages are unicode strings which carry a translation source domain and possibly a default translation. They are created by a message factory. The message factory is created by calling MessageFactory with the source domain.

This package provides facilities for declaring such messages within program source text; translation of the messages is the responsiblitiy of the 'zope.i18n' package.

Please see http://docs.zope.org/zope.i18nmessageid/ for the documentation.

In Zope3, location are special objects that has a structural location.

Proxies are special objects which serve as mostly-transparent wrappers around another object, intervening in the apparent behavior of the wrapped object only when necessary to apply the policy (e.g., access checking, location brokering, etc.) for which the proxy is responsible.

The Security framework provides a generic mechanism to implement security policies on Python objects.

pugixml is a light-weight C++ XML processing library. It features:

- DOM-like interface with rich traversal/modification capabilities
- Extremely fast non-validating XML parser which constructs the DOM tree from
an XML file/buffer
- XPath 1.0 implementation for complex data-driven tree queries
- Full Unicode support with Unicode interface variants and automatic encoding

The library is extremely portable and easy to integrate and use.

The robin-map library is a C++ implementation of a fast hash map and hash set
using open-addressing and linear robin hood hashing with backward shift
deletion to resolve collisions.
Four classes are provided: tsl::robin_map, tsl::robin_set, tsl::robin_pg_map
and tsl::robin_pg_set. The first two are faster and use a power of two growth
policy, the last two use a prime growth policy instead and are able to cope
better with a poor hash function. Use the prime version if there is a chance of
repeating patterns in the lower bits of your hash (e.g. you are storing
pointers with an identity hash function). See GrowthPolicy for details.
A benchmark of tsl::robin_map against other hash maps may be found here. This
page also gives some advices on which hash table structure you should try for
your use case (useful if you are a bit lost with the multiple hash tables
implementations in the tsl namespace).
