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:<foo@example.com>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 baz@example.com -q -o wam221@sussex.ac.uk 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')() File "/Users/wam22/mailmantesting/test4/mailman-3.0.0a1/mailman/bin/create_list.py", line 110, in main config.db.commit() File "/Users/wam22/mailmantesting/test4/mailman-3.0.0a1/mailman/database/__init__.py", line 79, in commit self.store.commit() File "/Library/Python/2.5/site-packages/storm-0.12-py2.5.egg/storm/store.py", line 107, in commit self._connection.commit() File "/Library/Python/2.5/site-packages/storm-0.12-py2.5.egg/storm/databases/sqlite.py", line 125, in commit self.raw_execute("COMMIT", _end=True) File "/Library/Python/2.5/site-packages/storm-0.12-py2.5.egg/storm/databases/sqlite.py", line 153, in raw_execute return Connection.raw_execute(self, statement, params) File "/Library/Python/2.5/site-packages/storm-0.12-py2.5.egg/storm/database.py", line 278, in raw_execute raw_cursor.execute(statement) 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?
