I'm interested in doing some FUSE stuff with Twisted, mostly to prototype some ideas for profiling. Can anyone expand on Glyph's comment [1]:
8< - - - - - - - - - - - - - - - - - - - - - - - - - - - - The Python FUSE bindings obscure the issue because, unlike the C libfuse, they assume that your filesystem I/O is blocking, which severely limits the performance of python-based filesystems. (You cannot receive more requests for I/O in your filesystem until the previous one has been completed with the pyfuse bindings, but you can in C.) 8< - - - - - - - - - - - - - - - - - - - - - - - - - - - - I guess I'd like to know before I sink too much time into this, if there's an approach to Fuse/Twisted that would not have this limitation. This is a bit confused by the fact that there are three Fuse/Python bindings that I'm aware of: FusePython, FusePy, and S3QL [2]. http://sourceforge.net/apps/mediawiki/fuse/index.php?title=FusePython http://code.google.com/p/fusepy/ http://code.google.com/p/s3ql/ If you've already been down this road, it'd be good to hear from you. Thanks Donal [1] Glyph's original mail: http://twistedmatrix.com/pipermail/twisted-python/2007-July/015784.html [2] S3QL has its own Python/Fuse bindings, according to this post: http://bugs.python.org/msg98077 ..on this issue: http://bugs.python.org/issue7736 _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
