Dumping queue files

The qfile command dumps the contents of a queue pickle file. This is especially useful when you have shunt files you want to inspect.

Pretty printing

By default, the qfile command pretty prints the contents of a queue pickle file to standard output.

>>> command = cli('mailman.commands.cli_qfile.qfile')

Let’s say Mailman shunted a message file.

>>> msg = message_from_string("""\
... From: aperson@example.com
... To: ant@example.com
... Subject: Uh oh
...
... I borkeded Mailman.
... """)

>>> shuntq = config.switchboards['shunt']
>>> basename = shuntq.enqueue(msg, foo=7, bar='baz', bad='yes')

Once we’ve figured out the file name of the shunted message, we can print it.

>>> from os.path import join
>>> qfile = join(shuntq.queue_directory, basename + '.pck')

>>> command('mailman qfile ' + qfile)
[----- start pickle -----]
<----- start object 1 ----->
From: aperson@example.com
To: ant@example.com
Subject: Uh oh

I borkeded Mailman.

<----- start object 2 ----->
{'_parsemsg': False, 'bad': 'yes', 'bar': 'baz', 'foo': 7, 'version': 3}
[----- end pickle -----]

Maybe we don’t want to print the contents of the file though, in case we want to enter the interactive prompt.

>>> command('mailman qfile --no-print ' + qfile)
