allno/yesconfig.py: Remove unused STR_TO_TRI imports

2017-11-20T07:08:25Z

Leftovers

allnoconfig.py: s/while 1/while True/

2017-11-09T20:31:07Z

Pointless as an optimization here. Should restrict obfuscating micro-optimization to the library code too even where it helps.

Simplify allyesconfig.py

2017-11-06T02:34:35Z

Can be implemented in a simpler/better way with Choice.assignable. Also rename 'conf' to 'kconf' in allnoconfig.py for consistency.

Simplify redundant 'is (not) None' tests in examples

Simplify allnoconfig.py choice handling

2017-11-05T05:46:19Z

Don't need to handle them at all now that .assignable doesn't claim that choice symbols in y-mode choices can be set to n. 20/20 hindsight.

Switch to a much faster invalidation algorithm

2017-11-01T05:04:10Z

_cached_vis is always calculated as a side effect of calculating any other cached value, and so doubles as a flag for whether an item (symbol or choice) has any cached values. If _cached_vis is None for some item, it also indirectly means that no other item can have any cached values that (actually) depend on the item, because _cached_vis would have gotten calculated as a side effect of calculating any such cached value. Therefore, it's safe to stop recursive invalidation at an item that has _cached_vis None. Huge speedup for the allyes/noconfig*.py scripts. allnoconfig_simpler.py went from 2.671 seconds to 1.067 seconds. The dependency selftests need to be updated too now that _get_dependent() is gone. The kernel defconfig tests pass even if all global invalidation is disabled at least (except for the few defconfigs that don't set MODULES=y), and that's a huge invalidation test. Seems pretty speedy too, even though there's some redundant work, so maybe things could be simplified a bit...

Consistently use 0/1/2 for tristate values

2017-10-30T00:14:20Z

Easier to work with, allowing e.g. direct comparisons with < and >. Make set_value() take 0, 1, 2 for bool and tristate symbols, and fix other APIs to match. Also: - Add introductions to various concepts in the module docstring. Document some more attributes. Still TODOs. - Rename the Config class to Kconfig. - Escape " and \ in the name of constant symbols when printing them. Also make the (un)escaping 100% consistent with how the C tools do it (\ before non-magic character should be unescaped too). - Clean up the escaping/unescaping code and provide two public escape()/unescape() functions. - Export the original MODULES-independent type in orig_type. It's needed for printing symbols in the reparsable __str__() Kconfig format with just public APIs. - Lots of other minor reorganizing and nits all over.

Nearly finalize API

Probably just some usability tweaks left. Having to do STR_TO_TRI[] for comparisons against 'assignable' values is kinda ugly and confusing.
