embedding a python FTP server

[jhack...@gmail.com]

Hi all,
I'd like to embed a FTP server in a python process having its own "serve_forever" loop (i.e. can't call server.serve_forever() from the __main__ entry point)
What's the best way to do so using pyftpdlib?
Should I run it into a dedicated thread? What's about performances in this case (shared GIL)?
Thanks.

Yes, you should run server.serve_forever() in a separate thread.

The test suite provides something like this:

https://github.com/giampaolo/pyftpdlib/blob/deeb9caad8f17f46329747fd8e34a22568b40524/test/test_ftpd.py#L226

That class is useful because you can start() and stop() the FTP server (if you want). I recommend you copy and paste it and customize it depending on your needs (all the things you should care about are in the __init__ constructor).

I don't think there will be any major performance issue.

Thanks a lot for the example.

I just had a look to the code. Exactly what I was looking for. Thanks again.
I simply noticed something weird @ line 279 of the provide example (in FTPd.start).
The call to FTPd.__init__ does not match the FTPd.__init__ signature.
BTW, why do you need to "ensure the server can be started again"?

[Giampaolo Rodola']

You are right, that is an error and since I never restart the server (as in start(); stop(); start()) during tests I never noticed it (legacy code I suppose).

There is one more thing I don't understand in the example: what is the aim of the mutex (i.e. self.__lock) in FTPd.run?
As far as I understand how a mutex work, the acquire/release sequence around self.__server.serve_forever is useless (there's only on thread executing FTPd.run).
Did I missed something? Something related to the underlying GIL?
Thanks for your help.

Good question. My honest answer is that I put it there because I experienced what looked like synchronization issues between threads (experienced under the form of test failures). A long time passed since then and now I no longer (or rarely) experience those failures anymore so it may be possible that those mutexes are useless now.
