Hi,

While trying to install ftputil on a new environment, I got this:

=====
Searching for ftputil

Looking at ftptuil wiki, I see its sqlite database is locked.


Thanks,

Thanks for sending your notice. :-) The locking seems to happen
from time to time. I don't know why, only that updating Trac
from the current Debian version lessened the frequency of
these lockups. Curiously, these locking problems seem to
vanish on their own sometimes (or by means of Trac?). Actually,
as I looked after the site, all I tested worked fine.

If you can post the exact error message I'd google to find
out if more is known since the last time I searched.

Best regards,
Stefan

Yes, I tried it again one hour later and everything run nice (I though
you have fixed).

Sorry, didn't save the whole message... But I'll do it if it happens again.  :)

Subject: [ftputil] Problem with session_factory: __init__() takes at most 5
 arguments (6 given)
Message-ID: <47DE69F2.8090000@alice.it>

Hi all!!
This is my first message here, and I would compliment with you ;)

However, I'm developing a little ftp client for personal use, using 
ftputil library, very simple and useful.

But now I've a little problem:

I've this class:

class ActiveFTPSession(ftplib.FTP):
    def __init__(self, host, userid, password):
        ftplib.FTP.__init__(self)
        self.connect(host, port)
        self.login(userid, password)
        # see http://docs.python.org/lib/ftp-objects.html
        self.set_pasv(False)

and this:

class FTPConnection(object):
    def __init__(self, host, userid, password, port, session_factory):
       
        self.host = host
        self.userid = userid
        self.password = password
        self.port = port
        self.session_factory = session_factory

        try:
            self.connection = ftputil.FTPHost(self.host, self.userid,
                     self.password, self.port, self.session_factory)

        except ftputil.FTPError, e:
            print "Errore"
            print e

When I try to run the main:

try:

        fc =  FTPConnection(HOST, USERID, PASSWORD, PORT, ActiveFTPSession)

except Exception, e:
        raise FTPConnectionError("Non e` stato possibile effettuare "\
                                    "la connessione:\n%s" % e)
        quit()

I receive this error:

Traceback (most recent call last):
  File "main.py", line 37, in <module>
    "la connessione:\n%s" % e)
src.FTPConnection.FTPConnectionError: Non e` stato possibile effettuare 
la connessione:
__init__() takes at most 5 arguments (6 given)

It's saying me that I pass 6 arguments instead of 5.
What's the matter?

Thank you ;)

session_factory has to be a keyword argument, not a positional argument,
i. e. change

self.connection = ftputil.FTPHost(self.host, self.userid, self.password,
                  self.port, self.session_factory)

to

self.connection = ftputil.FTPHost(self.host, self.userid, self.password,
                  self.port, session_factory=self.session_factory)

The ftputil documentation says:

"""
In fact, all positional and keyword arguments other than session_factory
are passed to the factory to generate a new background session ...
"""

Since all positional arguments are passed directly to the session
factory callable, the session_factory argument itself has to be a
keyword argument.

Since the ftputil.FTPHost constructor can't recognize and "filter"
the session_factory argument, it tries to stuff the extra argument
in *args and passes this to the _default_ factory, ftplib.FTP.
However, ftplib.FTP's constructor takes at most five arguments
(including self), so you have passed in one argument too much.

Have fun! :)

Best regards,
Stefan

Subject: [ftputil] Setting a passive/active connection during the same
	connection
Message-ID: <47E689E0.10101@alice.it>

Hi!

Is there a way to set a modality passive/active during the connection 
and not only before the connection ?

Infact with ftplib we have:

ftp = ftplib.FTP(host,user,pass, port) #or some similar
ftp.set_pasv(True|False)

Instead in ftputil we have to define a class as in the example in the 
documentation.

Can you help me?

Bye.

Principally, the instantiated session object is accessible
as FTPHost._session. Accessing it, for example via
host._session.set_pasv(True) is not recommended: ftputil
makes new sessions internally for child session objects
which are used for file-like objects.

So the recommended way is still to use a session factory
callable - unless you are hundred percent sure you avoid
use FTP file-like objects and want to risk compatibility
problems with future ftputil versions. ;-)

Note that the session_factory can by any callable, not
necessarily a class. Thus, you could use

def factory(host, user, pass, port):
    session = ftplib.FTP(host, user, pass, port)
    session.set_pasv(True)
    return session

host = ftputil.FTPHost(host, user, pass, port,
                       session_factory=factory)

which is a bit shorter than using a class as the session
factory.

Best regards,
Stefan

I didn't thought of this method. But I think, as you say it's not a good 
method.

I've already used this method, but I've found a little (big) problem.
Imagine you want to switch to active from passive or vice versa during 
an established connection. You've to instanciate another FTPConnection 
object, haven't you? So the previous connection is lost, and you've to 
create a new connection. It' s not a good way .. :(

For example, if you use linux and open a ftp command line client, you 
can set passive/active at whatever time you want.

What do you suggest me?
Thank you for your helping me.
Regards.

Is this an actual use case? If yes, could you describe the
concrete application in more detail? Is it actually bad for
performance (or otherwise) to open a new connection?

Again, I wonder whether this (changing at any time) is
needed. I think, also in command line clients you _usually_
change active/passive mode not more than once per
connection.

If you actually have an application which (according to
measurements!) benefits from switching the mode on an
established FTPHost instance please tell me. :-) You can
compare the approaches by accessing FTPHost._session
directly; just for tests, not production code, this should
be ok.

I can _imagine_ a use case for changing the mode of the
session after establishing the connection: You try some
commands, and if they fail, you retry after switching from
active to passive (or vice versa). However, if you deal
with a certain remote host, you will probably need this
switching only one time and reuse the knowledge of active/
passive mode for multiple connections. So the loss of
reopening a single connection for dealing with - in the
end - several connections to a server for some time
probably isn't critical, only a bit inconvenient.

You're welcome (as always). :-)

No, but I thought:
I estabilish a new connection object in passive mode. I do my work, 
change directory, etc etc... Then I disconnect this object to connect in 
active mode. I lose all my data (local directory, etc..)

If you try to connect, for example, to a host:
    ftp upload.sourceforge.net
    # you login
    ftp> ls
    200 PORT command successful. Consider using PASV.
    150 Here comes the directory listing.

It's saying you that you are using active mode, and you've to set 
"passive" (because sourceforge works in this way).
Than you set "passive" and it works well.
I can see that once you 've changed to passive mode, you can't return to 
active mode. (maybe it depends on the server?)

No, I don't know any applications that do this.
So the user should switch only one time to passive/active mode.

Infact I'm thinking of estabilishing only one connection at time.

Ok. I'll do so:

    def factory(host, user, pass, port):
        session = ftplib.FTP(host, user, pass, port)
        session.set_pasv(True)
        return session

    host = ftputil.FTPHost(host, user, pass, port,
                           session_factory=factory)


It's a good method

Thank you!! :)
