[Pyobjc-dev] FTP Lib with a Cocoa application

[Rob <rob...@gm...>]

My apologies if this has already been discussed  / answered, but I couldn't
figure out how to search the archives.
I am writing a Cocoa based FTP uploading application using ftplib and
threading and I've hit a bit of a snag.  I am sure it is something I am
doing wrong, but I wanted to check to see if I am way off.

What appears to be happening is when I run the application within the Cocoa
GUI the FTP uploading part hangs when it tries to do the upload (staring
it's own thread I am assuming).  I am guessing it's a "thread in a thread"
issue? (total guess obviously)

When I run the threaded library directly from __main__ on the command line,
with FTP set to debug I get the following:

*cmd* 'TYPE I'
*put* 'TYPE I\r\n'
*get* '200 Type set to I\r\n'
*resp* '200 Type set to I'
*cmd* 'PASV'
*put* 'PASV\r\n'
*get* '227 Entering Passive Mode (xxx,xxx,xxx,212,4,3)\r\n'
*resp* '227 Entering Passive Mode (xxx,xxx,xxx,212,4,3)'
*cmd* 'STOR TestFile.mov'
*put* 'STOR TestFile.mov\r\n'
*get* '150 Connection accepted\r\n'
*resp* '150 Connection accepted'
*get* '226 Transfer OK\r\n'
*resp* '226 Transfer OK'
*cmd* 'QUIT'
*put* 'QUIT\r\n'
*get* '221 Goodbye\r\n'
*resp* '221 Goodbye'
Done.

However when I run the same code within Cocoa I get the following:

**cmd* 'TYPE I'*

**put* 'TYPE I\r\n'*

**get* '200 Type set to I\r\n'*

**resp* '200 Type set to I'*

**cmd* 'PASV'*

**put* 'PASV\r\n'*

**get* '227 Entering Passive Mode (xxx,xxx,xxx,212,4,4)\r\n'*

**resp* '227 Entering Passive Mode (xxx,xxx,xxx,212,4,4)'*

And it just hangs there.  It never gets to the next line.

The library that does this is a threaded class: class FTPFile(Thread): that
just runs a typical ftp connection and upload in the run method:

def run(self):

        ftp = FTP(

                    self.config.server,

                    self.config.username,

                    self.config.password)

etc, etc

I can FTP via the command line "ftp" application, and, like I said, when I
run the library directly so I don't think it's a server problem.  Is there
something I may have missed when creating the Cocoa app? Do I have to
explicitly allow FTP connections or something (I also have the firewall
off)? Or is this a known issue with Cocoa+Python?

Thanks for any help,
rob
