Why are there two deferred objects returned by storeFile? The documentation
storeFile (self ,path ):
Store a file at the given path.
This method issues the 'STOR' FTP command.
A tuple of two Deferreds:
* Deferred IFinishableConsumer . You must call the finish method on the
IFinishableConsumer when the file is completely transferred.
* Deferred list of control-connection responses.
This really doesn't help me much. I get the impression that storeFile
isn't sending the contents of file, because its waiting for me to stream
the file contents somehow. Maybe via IFinishableConsumer?
In my current program, using ftplib, I do the following to upload a file:
ftp.storbinary('STOR %s' % (filename), fp)
This has the filename and a file descriptor passed to it. Is something
needed with storeFile?
Please can someone give me an answer to this, as looking at the code for
twisted.protocols.ftp isn't helping much either. This function seems to be
a mystery to me and I want to understand how to use it properly.
