Kconfiglib.git, branch v2.5.0

Make 2.5.0 release

2018-01-25T01:47:29Z

- 955ea4 ("Support <, > relational operators with tristates") adds a small recent feature from upstream. Haven't even seen any relational operators besides = and != being used yet I think. - 8d7235 ("Tighten up regexes") cleans up and optimizes the regexes used during parsing and .config reading a bit.

Tighten up regexes

2018-01-25T01:21:53Z

- Match the simpler strchr()y .config parsing done by the C implementation - Spell out \w as [a-zA-Z0-9_]. Easier to verify. - Use ASCII mode for Python 3 to be consistent with Python 2, where it's already the default. \s no longer matches obscure Unicode stuff. This also speeds up regex matching during parsing by about 15% on Python 3, increasing parsing performance by a few %. Looks like there's a tiny improvement for Python 2 as well.

Support <, > relational operators with tristates

2018-01-24T23:18:40Z

Mirrors 9059a3493ef ("kconfig: fix relational operators for bool and tristate symbols") in the C implementation.

Mention the reltest script

Make 2.4.0 release

2018-01-24T05:18:27Z

Just has b82ea0a ("Enable universal newlines mode for Python 2").

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.

Make 2.3.0 release

2018-01-24T01:55:02Z

Just adds a new warning: 0087b40 ("Warn if a symbol with unsatisfied deps is selected")

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)

Mention loading of multiple .config files
