Make UNKNOWN falsy

2018-11-03T20:12:06Z

Set UNKNOWN (representing 'no type') to 0, which is falsy, to simplify some checks. Also reorder some dictionary keys for consistency.

Fix removal of multiple consecutive 'if' nodes

2018-11-02T02:52:46Z

Despite 'if' nodes being flattened before 'if' removal, consecutive 'if' nodes can still show up for code like the following: ... if X endif if X endif ... _remove_ifs() failed to remove the second 'if' node, leading to a crash e.g. when turning on show-all mode in the menuconfig in a menu with such code (due to the unexpected 'if' node). Stuff like the above could potentially result from 'osource's with no matches, though I just spotted the error while looking over the code. Fix the 'if' removal logic to properly handle consecutive 'if' nodes.

Don't show backtraces for expected exceptions in tools

2018-11-01T02:21:09Z

KconfigError and IOError are part of normal operation and don't indicate a problem with the library itself. Catch and print them in standard_kconfig() and sys.exit(), to avoid spammy backtraces from e.g. menuconfig.py when Kconfig files don't exist or have errors.

Refactor _remove_ifs()

2018-11-01T00:18:38Z

Can get away with a single variable by assigning node.list earlier, and save a tiny bit of work with a chained assignment. Also clarify what the tricky Python chained assignments correspond to, where it matters.

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

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
