I'm pleased to announce the first bugfix release of the "RSFile" package.

Issues addressed:
- rejection of unicode keys in kwargs arguments, in some versions of py2.6
- indentation bug swallowing some errors on file opening

----

RSFile aims at providing python with a cross-platform, reliable, and 
comprehensive file
I/O API. It's actually a partial reimplementation of the io module, as 
compatible possible
(it passes latest stdlib io tests), which offers a set of new - and 
possibly very useful - features:
shared/exclusive file record locking, cache synchronization, advanced 
opening flags, handy stat
getters (size, inode...), shortcut I/O functions etc.

Unix users might particularly be interested by the workaround that this 
library provides, concerning
the catastrophic fcntl() lock semantic (when any descriptor to a file is 
closed, your process loses ALL
locks acquired on it through other streams).

RSFile has been tested with py2.6, py2.7, and py3.2, on win32, linux and 
freebsd systems,
and should theoretically work with IronPython/Jython/PyPy (on Mac OS X too).

The technical documentation of RSFile includes a comprehensive description
of concepts and gotchas encountered while setting up this library, which 
could
prove useful to anyone interested in getting aware about gory file I/O 
details.

The implementation is currently pure-python, as integration with the C 
implementation of io module
raises lots of issues. So if you need heavy performances, standard 
python streams will
remain necessary. But for most programs and scripts, which just care 
about data integrity, RSFile
should be a proper choice.

Regards,
Pascal Chambon

PS : Due to miscellaneous bugs of python core and stdlib io modules 
which have been fixed relatively recently,
it's advised to have an up-to-date minor version of python (be it 2.6, 
2.7 or 3.2) to benefit from RSFile.
