CRAPI: Common Range API

Project description

**Welcome to CRAPI!**

**CRAPI** (spelled "crap-i" - and hoping not to be such one despite its
name) or **Common Range API** is a library meant to ease the development
in various areas of Linux and Windows using one common API. The library
aims to be a highly stable version of common programming practices,
constructs and OS native functions & tools with a dedicated mindset in:

- Portability in Windows since Windows API is huge and complicated
- Portability in both OSes (Windows & Linux alike)
- Performance

We aim to cover most common scenarios beyond the basic API mechanisms
(i.e. building a multithreaded pipe server, Windows services/Linux
daemon etc) that will be provided to you however not every scenario will
be covered. Minimally, priority will be given to the foundation
mechanisms so you may be able to build whatever you want (hopefully).

**Security issues** and **implementation correctness** are always a
priority and will be taken into account however do note that until we
reach a production/stable status we do not accept input but
suggestions/comments and/or feedback are always welcome :)

**Operating system support**

Windows 7/8/8.1/10, Windows Server 2008 R2/2012 R2/2016 & major Linux
variants:       Debian 7.x and 8.x (untested) & CentOS/RHEL 6.6 and 6.7
(tested). Mac OS X is **NOT** supported (unless you buy me one maybe?).


- Python 2.6 or 2.7 with latest version of pip, wheel and setuptools.
**Windows distributions**: Guess what? You need Mark Hammond's
pywin32 module. Please use the one provided here: pywin32-Build 219
by Christoph Gohlke and make sure to follow the installation
instructions correctly.

**Why another library?**

How many times have you been forced to see this (non-parameterized
example code for illustration purposes)?

.. code:: python = win32security.SECURITY_ATTRIBUTES() = True
self.__hPipe = win32pipe.CreateNamedPipe(

or maybe this (from the MessageBroker library which uses MSMQ):

.. code:: python

pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, u'MSMQQueueInfo',
u'The queue does not exist or you do not have sufficient permissions to perform'
'the operation.', None, 0, -1072824317), None)

A Python developer shouldn't have to figure this out especially when
it's crafted in a non-Pythonic, untypical way.

Noone should have to do this. That's why we have attempted to do it FOR
you WITHOUT you :P.

P.S.: The above are not meant to criticize Mark Hammond's **pywin32**
excellent library. Merely, they indicate the difficulties a developer
has to deal with by being forced to use heterogeneous components and
source code due to different OSes with incompatible APIs and native


It's based on Apache Software License 2.0 (ASF 2.0) so without
suggesting that this constitutes a legal advice in any way, shape or
form: Do whatever the f\*\*\* you want with it as long as you give us
proper credit! :}


The authors strive for a stable and coherent source code base however it
should be considered experimental and pre-alpha and, as such, not
production-ready so use at your own risk! In addition, the authors makes
no guarantees that the code is of top-notch quality (any Win folks
here?). You have been (fore)warned!!! :]


Currently, only MS Windows is supported. Linux support coming soon :]
