Hi,
I'm trying to work out how to report a bug in Mailman 3.0
None seem to be listed at <https://bugs.launchpad.net/mailman>
The bug seems to be in the lmtp queue runner. If I try to create a new list
while the queue runner is handling a connection, mailman.db gets
permanently locked.
So, if I telnet to the lmtp server, and say:
220 quant.staff.uscs.susx.ac.uk Python LMTP queue runner 1.0
lhlo me
250 quant.staff.uscs.susx.ac.uk
mail from:<>
250 Ok
rcpt to:<[EMAIL PROTECTED]>
then, I switch to another shell, and try to create a list with create_list:
quant:mailman-3.0.0a1 its$ staging/bin/create_list -l [EMAIL PROTECTED]
-q -o [EMAIL PROTECTED]
Traceback (most recent call last):
File "staging/bin/create_list", line 8, in <module>
load_entry_point('mailman==3.0.0a1', 'console_scripts',
'bin/create_list')()

sqlite3.OperationalError: database is locked
And, it stays locked like that for eternity, or until I remove
var/data/mailman.db-journal (whichever comes sooner ;)
The question is, why would the lmtp server need a write lock on the
database?
