RSFile advanced I/O file streams
RSFile provides pure-python drop-in replacements for the classes of the io module, and for the open() builtin.
Its goal is to provide a cross-platform, reliable, and comprehensive synchronous file I/O API, with advanced features like fine-grained opening modes, shared/exclusive file record locking, thread-safety, cache synchronization, file descriptor inheritability, and handy stat getters (size, inode, times…).
Possible use cases for this library: concurrently writing to logs without ending up with garbled data, manipulating sensitive data like disk-based databases, synchronizing heterogeneous producer/consumer processes when multiprocessing semaphores aren’t an option…
This version 2 of the lib drops support for Python2.6, and puts RSFile in compliance with the numerous evolutions that happened to the I/O modules of the stdlib, over the past years.
Tested on python2.7 and python3.3+, on windows and unix-like systems. Should work with IronPython/Jython/PyPy too, since it uses stdlib utilities and ctypes bridges.

Using pip is recommended, although installing from a checkout of the repository (via setup.py) also works:
$ pip install rsfile
from rsfile import rsopen with rsopen("myfile.txt", "w") as f: f.write(u"This string will be veeeeeryyyyy safely written to file.") with rsopen("myfile.txt", "WANISB", locking=False, thread_safe=False) as f: f.write(b"See the docs for info on these cool new modes and parameters.")
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
