Make errno/strerror/filename available on IOError

2018-10-30T23:02:43Z

An error reporting flaw was that most raised IOErrors got their errno/strerror/filename fields stripped, due to wanting to show a custom messages. The problem was that adding back 'errno' and 'strerror' made IOError.__str__() always return a fixed string ("[Errno ] "), ignoring any custom message. This is friendly to users, but unfriendly to scripts (the menuconfig had a workaround). Make things friendly to both by raising an internal subclass of IOError instead, that preserves errno/strerror/filename but prints a custom message. The exception can then still be caught as IOError/OSError by scripts.

Simplify _INIT_SRCTREE_NOTE definition

2018-10-30T22:02:20Z

Remove no longer needed 'node.item is None' tests

2018-10-30T22:02:13Z

After commit e0256b6 ("Have MENU and COMMENT match _T_MENU and _T_COMMENT"), the only falsy value for node.item is None, since all token constants are truthy (since they're never 0).

Replace 'indent == 0' with 'not indent'

2018-10-28T17:28:40Z

Tiny bit faster and smaller. Clear in context.

Have MENU and COMMENT match _T_MENU and _T_COMMENT

2018-10-28T16:54:26Z

Same approach as for the expression type symbolic constants. Removes a tiny bit of conversion and makes things a bit more consistent.

Shorten exception class definitions a bit

2018-10-28T15:54:50Z

Remove leftover comment in _add_choice_deps()

2018-10-28T14:38:28Z

Made more sense when the code was part of _build_dep(). The same thing is explained in the function docstring now.

Micro-optimize dependency loop checking

2018-10-28T14:12:07Z

Turn the _check_dep_loop_sym lookup into a LOAD_FAST inside the loop.

Support enabling the assignment-to-undef. symbol warning via the environment

2018-10-26T21:34:18Z

This makes it possible to enable it for the bundled tools, by setting KCONFIG_WARN_UNDEF_ASSIGN=y. Previously, the code had to be modified to call Kconfig.enable_undef_warnings(). Also rename KCONFIG_STRICT to KCONFIG_WARN_UNDEF, for consistency. Keep supporting KCONFIG_STRICT as an alias for backwards compatibility.

Move _is_num() into _check_undef_syms()

2018-10-24T22:51:43Z

_check_undef_syms() is the only caller.
