[Pythonmac-SIG] app does not run when launched via main.py import was:py2app- python code packed in clear ascii

Thu Nov 20 12:26:40 CET 2008

I tried via the import and it converts my main app to bytecode (see post on bottom). THANKS FOR THE HELP.
However, now I face a strange problem even before I build an app bundle. the mainfile.py runs perfect when launched alone.
But when run via main.py it hangs when Upload button is presses.
I susspect either wx.callback or the thread- but right now I am lost.
NOTE: I use a patched ftplib, so I get a callback from an upload proces, which ftplib by default only supports for download. I include the extra lines I added to ftplib.py.

my main.py looks like this:

# /usr/bin/pythonw
import mainfile

mainfile.py is a small ftp upload app which uses wx.Miniframe and thread

================================================================

patch for ftplib.py to support a callback for uploads:
Append to your ftplib.py:
===========================================================
    def newstorbinary(self, cmd, fp, blocksize=8192, callback = None):#this version includeds a callback
        '''Store a file in binary mode.'''
        #CRLF = ftplib.CRLF
        self.voidcmd('TYPE I')
        conn = self.transfercmd(cmd)
        while 1:
            buf = fp.read(blocksize)
            if not buf: break
            conn.sendall(buf)
            if callback: callback(buf)
        conn.close()
        return self.voidresp()
