Kconfiglib.git/kconfiglib.py, branch v2.4.0

Enable universal newlines mode for Python 2

2018-01-24T04:01:20Z

Use the "U" flag to open() rather than io.open() to avoid a ~14% parsing performance hit. See comment.

Warn if a symbol with unsatisfied deps is selected

2018-01-24T01:43:07Z

Mirrors a warning in the C implementation. Make it a bit more informative and simpler to decode for people who aren't super familiar with Kconfig. The warning is printed when/if the symbol is evaluated, e.g. when writing a .config or C header or accessing Symbol.str/tri_value. It is not printed if the symbol value has already been calculated and is cached and up-to-date, which avoids warning spam. Example: config Y_SYMBOL_1 def_bool y config Y_SYMBOL_2 def_bool y config SELECTED bool depends on !Y_SYMBOL_1 config SELECTING_1 def_bool y select SELECTED # Skipped in warning, because n config SELECTING_2 def_bool n select SELECTED config SELECTING_3 def_bool y select SELECTED if Y_SYMBOL_1 depends on Y_SYMBOL_2 # Defined in multiple locations config SELECTING_3 Generated warning: warning: SELECTED (defined at Kconfig:7) has unsatisfied direct dependencies (!Y_SYMBOL_1), but is currently being selected by the following symbols: SELECTING_3 (value: y, defined at Kconfig:20, Kconfig:26), with direct dependencies "y" (value: y) and select condition Y_SYMBOL_1 && Y_SYMBOL_2 (value: y) SELECTING_1 (value: y, defined at Kconfig:11), with direct dependencies "y" (value: y) Real-world example from test suite: warning: NOT_COHERENT_CACHE (defined at arch/powerpc/platforms/Kconfig.cputype:381) has unsatisfied direct dependencies (4xx || PPC_8xx || E200 || PPC_MPC512x || GAMECUBE_COMMON), but is currently being selected by the following symbols: AMIGAONE (value: y, defined at arch/powerpc/platforms/amigaone/Kconfig:2), with direct dependencies 6xx && BROKEN_ON_SMP (value: y) and select condition 6xx && BROKEN_ON_SMP (value: y)

Add some more detail to the module docstring

2018-01-22T19:45:59Z

Clarify how to fetch help texts and prompts, mention the no-prompt warning.

Simplify escape()

2018-01-22T19:04:41Z

The fancy regex isn't really justified. Much faster with replace() too, though this is an unlikely hotspot. Could have used a \g<0> backreference to refer to the entire match instead of using a capturing group too. Hadn't discovered that. Add some selftests for escape() and unescape() too.

Mention user_value in the load_config() docstring

2018-01-22T17:33:06Z

Can be handy to check which symbols got set, like merge_config.py does.

Fix outdated comments referencing user_str/tri_value

2018-01-22T04:16:43Z

Ended up with just user_value in the end before releasing Kconfiglib 2.

Add more detail to the write_autoconf() docstring

2018-01-22T04:13:14Z

Same order as for .config files.

Add more detail to the write_config() docstring

2018-01-22T04:02:46Z

Can be handy to know that the order of the assignments matches the Kconfig files.

Micro-optimize _T_HELP parsing

2018-01-20T05:22:37Z

Shaves a few % more from _parse_properties().

Get rid of _next_help_line()

2018-01-20T04:19:42Z

Speeds things up a bit further. Rework the unget handling to save the ungotten line directly instead of using a flag. Add some help texts to tests/Klocation to make sure the line number is updated properly for those.
