Hi Everyone,
I just have started to study twistedmatrix in my spare time couple of weeks
ago. I am satisfied with the books, but as they are very terse, and they are
not really FTP related, I could not figure out how the FTP is working.
I would like to be able to filter/modify the LIST(ing) process. Eg after
list(ing) the result should not list any .py files even if they are there.
I have tried to look after IFTPShell, but no success sofar. Here is a code
snipplet from the "official" testcases - or even from twisted.ftp)
IFTPShell is the way you control the behavior of the FTP server. To exclude
certain results from a directory listing, you would implement the `list´
method so that it has the necessary logic for performing that exclusion.
def requestAvatar(self, avatarId, mind, *interfaces):
for iface in interfaces:
if iface is ftp.IFTPShell:
avatar = ftp.FTPShell(filepath.
FilePath(self.root))
return ftp.IFTPShell, avatar, getattr(avatar, 'logout',
lambda: None)
Could anybody give me any advice, where to start, please?
You found an implementation of a realm which supports IFTPShell. If you
aren't familiar with realms, read the cred documentation:
http://twistedmatrix.com/projects/core/documentation/howto/cred.html
The realm is important but pretty simple. The avatar, the IFTPShell
implementation, is what really controls the behavior you're interested
in.
