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.
