Even though queries may not contain non-utf8 code points
InvalidQueryError ought to be prudent, for such an invalid query would
raise an InvalidQueryError which therefore has to be able to manipulate
the invalid query.
Test usqge of SQL's substr() with a UTF8 example. The ideal would be to
test with non-UTF8 code points, however it is impossible to perform such
a query: queries can only be unicode or utf8.
interactive_open() takes a target and an optional command, if it does not
receive a command then it uses open_anything().
It parses command and lexes it with shlex.split(), revieling the client
from that task.
"config -e" command uses it, and gives a better error message in case of
problem. "play" plugin uses it as well, as side-effect being that the
command is now interactive, as requested in issue #1321.
Fix issue #1321.
'verbose' is now an int and not a boolean. '-v' is level 1, '-vv' level
2. In the configuration it can be set with 'verbose: 1' or 'verbose: 2'.
Improve #1244: auditing current log levels of plugins remains.
Delete the remaining usages of BeetsPlugin.listen().
Since BeetsPlugin.listeners are wrapped by a loglevel-setting function,
we cannot easily check their unicity anymore.
BeetsPlugin._raw_listeners set holds the raw listeners.
Legacy plugins that did not handle enough arguments in their listenings
functions may break: dedicated code is now deleted for it would not work
with the decorated listeners.
Tests got fixed. Some modifications were done empirically: if it passes
then it's okay.
Listeners get logging level modulations, like import_stages already did.
Add extensive tests:
- explicit plugin commands are logged like core beets (INFO or DEBUG)
- import stages are more silent
- event listeners are like import stages
Delete @BeetsPlugin.listen decorator since listeners need plugin instance
context to set its logging level.
Improve #1244. Next is multiple verbosity levels.
Places where InvalidQueryArgumentTypeError may be raised (i.e. all
current ones) may not know the query therefore it cannot be an
InvalidQueryError. The InvalidQueryArgumentTypeError is caught in
beets.library.Library._fetch() and an InvalidQueryError is then raised.
Improve #1290.
Replace previous InvalidQueryError with InvalidQueryArgumentTypeError
which extends the former as TypeError. However they lack context: the
query that caused the error.
Raise an InvalidQueryError when a shell-like expression cannot be parsed
by shlex.
Improve #1290.
