Ivan Levkivskyi added the comment: SETUP_ANNOTATIONS and STORE_ANNOTATION opcodes are documented in documentation for dis module. Should they be documented also somewhere else? -- nosy: +levkivskyi ___ Python tracker <http://bugs.python.

[issue28869] __module__ attribute is not set correctly for a class created by direct metaclass call

New submission from Ivan Levkivskyi: __module__ attribute is set differently depending on whether a metaclass is explicitly called or invoked in a class statement: >>> A = ABCMeta('A', (), {}) >>> A.__module__ 'abc' >>> class B(metaclas

[issue28869] __module__ attribute is not set correctly for a class created by direct metaclass call

Ivan Levkivskyi added the comment: > As a matter of fact, A.__module__ in this case is abc.ABCMeta.__module__. A > class body creates a __module__ key, while a direct metaclass call does not. But >>> A = ABCMeta('A', (), {}) >>> ABCMeta.__module__ = '

[issue28339] "TypeError: Parameterized generics cannot be used with class or instance checks" in test_functools after importing typing module

Ivan Levkivskyi added the comment: The failure is fixed now, but it is fixed not in an elegant way (sys._getframe is used). I think this is not urgent. If there are no objections, then I would propose to change priority to normal. -- ___ Python

[issue25458] ftplib: command response shift - mismatch

Ivan Pozdeev added the comment: The current solution looks fishy to me. We should stick to https://tools.ietf.org/html/rfc959 . In particular, 226 is sent when the server closes the auxiliary socket, so the module should react accordingly. Debug printing and/or issuing warnings is an obvious

[issue28923] Nonexisting encoding specified in Tix.py

New submission from Ivan Pozdeev: $ head 'c:\Py\Lib\lib-tk\Tix.py' -n 1 # -*-mode: python; fill-column: 75; tab-width: 8; coding: iso-latin-1-unix -*- There's no "iso-latin-1-unix" encoding in Python, so this declaration produces an error in some code analysis tools

[issue25458] ftplib: command response shift - mismatch

Ivan Pozdeev added the comment: Found the root problem: a 1xx response doesn't complete a LIST command, it should wait further for a 2xx one. See RFC 959 section 6 (state diagrams). This could be `urllib`'s rather than `ftplib`'s fault: the former calls low-level subroutine
