ANN: pysendfile released

[Giampaolo Rodolà]

I released it just now:
http://code.google.com/p/pysendfile/

I think this is worth mentioning as starting from the next pyftpdlib version (we're almost there) we're going to make use of this as an (optional) third party dependency (see bug tracker issue: http://code.google.com/p/pyftpdlib/issues/detail?id=152).

Use of pysendfile will make uploads (RETR, hence from server to client) about 3x faster, which is very close to the transfer rates reached by proftpd and vsftpd servers (which are written in C).
As such, this goes to all those people avoiding python because "it's slow". ;-)

How can I use this with pyftpdlib? Or can I? If so, can you give me an example?

Anyway, thanks!! :-)

Hi Thomas.
As for now (until 0.7.0 will be released) you can use latest SVN revision:

$ svn checkout http://pyftpdlib.googlecode.com/svn/trunk/ pyftpdlib

To enable sendfile(2) usage you must install pysendfile module first:

$ easy_install pysendfile

pyftpdlib will detect its presence (import sendfile) and automatically
use it for uploads (RETR) if available.
Whether using sendfile(2) is governed by
pyftpdlib.ftpserver.FTPHandler.use_sendfile attribute (a bool).
The bool defaults to False if pysendfile module is not installed.
