Add a fast path for string parsing

2018-11-07T04:59:20Z

For strings with no $ or \ in them (99.86% of all strings in the Linux x86 Kconfigs), we can just find() the matching quote directly. Saves a few % of tokenization time.

Always strip trailing whitespace in 'MenuNode.help' and str()

2018-11-06T10:48:42Z

Previously, you could get either one or two newlines at the end of MenuNode.help and the various __str__() methods, though this wasn't documented. Always stripping trailing whitespace is cleaner e.g. when using print(), which automatically appends a trailing newline, and makes things consistent. Hopefully nothing relied on the old undocumented behavior. It's fine for genrest.py at least.

Make UNKNOWN falsy

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.
