Fork of https://github.com/zephyrproject-rtos/Kconfiglib.git https://git.mcdonnell.dev/Kconfiglib.git/atom?h=v8.1.0 2018-07-11T12:55:25Z 2018-07-11T12:55:25Z Ulf Magnusson ulfalizer@gmail.com 2018-07-11T12:19:49Z urn:sha1:47ab37c4e7c5c917bb57c0a6bdfbca72d2f2941d This release improves performance for projects that make heavy use of multiple definition locations for symbols, via commit 747e455 ("Massively speed up U-Boot parsing"). Two new warnings are included as well: - 652d991 ("Warn if int/hex/string symbols are evaluated logically") - 21b5351 ("Warn if int/hex 'default' is outside active 'range'") 2018-07-11T12:55:25Z Ulf Magnusson ulfalizer@gmail.com 2018-07-11T08:25:41Z urn:sha1:71872a88641f713dfa986906e860c320a74fd84a U-Boot has a ton of definition locations for some symbols, causing a lot of redundant work when iterating over Kconfig.defined_syms in _build_dep(). Iterate over set(Kconfig.defined_syms) instead, wherever possible. This speeds up the U-Boot parsing time from 4 seconds to 0.6 seconds on my machine. Also update the bundled tools to iterate over set(Kconfig.defined_syms). The performance loss is negligible even for projects that don't use multiple definition locations. Update the documentation to clarify that symbols/choices defined in multiple locations appear multiple times in Kconfig.defined_syms/choices as well. 2018-07-11T12:55:25Z Ulf Magnusson ulfalizer@gmail.com 2018-07-11T04:23:44Z urn:sha1:f0a8a4d86e4c52b401f543737d76ae8392247300 2018-07-10T13:21:02Z Ulf Magnusson ulfalizer@gmail.com 2018-07-10T13:21:02Z urn:sha1:e927c3722aeba9fa5336b92bf8ca6967f28bd70f More environment variables are referenced now. 2018-07-10T12:41:43Z Ulf Magnusson ulfalizer@gmail.com 2018-07-10T12:41:43Z urn:sha1:547fced630611e7554d05e4f69f01957c9fc35d4 2018-07-10T12:19:04Z Ulf Magnusson ulfalizer@gmail.com 2018-07-10T12:16:08Z urn:sha1:21b5351c3721359dbd28937c95e75ba4b435f0b7 Only out-of-range user values generated warnings before. The C tools warn for neither of them. 2018-07-10T11:30:43Z Ulf Magnusson ulfalizer@gmail.com 2018-07-10T11:23:14Z urn:sha1:652d9916b12e1b2ee918b61d04ff23226d2fa4cd They always evaluate to n. Would be nice if there was a trivial way to give the location(s). Just say "somewhere" for now. 2018-07-10T07:13:54Z Ulf Magnusson ulfalizer@gmail.com 2018-07-10T07:13:07Z urn:sha1:8ff1be9dcf7d7d30fce553b0ed21b40bbc26cae7 New features: - 2433deb ("Add Kconfig preprocessor") implements a new Kconfig preprocessor, documented in https://github.com/torvalds/linux/blob/master/Documentation/kbuild/kconfig-macro-language.txt. It is required to parse the linux-next Kconfigs now, and will appear in Linux 4.18. 'option env=...' symbols and the $FOO syntax for expanding environment variables will be supported for backwards compatibility for a while. Consider switching to $(FOO) though, which is the new syntax (and removing 'option env=...' symbols). Changed behavior: - c19fc11 ("Drop some compatibility and tighten up lexing") makes Kconfiglib flag invalid characters in Kconfig files as a syntax error in all context. They were previously ignored in some places for compatibility with old sloppy versions of the C tools. The C tools fixed it with commit c2264564 ("kconfig: warn of unhandled characters in Kconfig commands") in July 2015. Older kernels might require fixing up the Kconfig files a bit now. New warnings: - 4200e25 ("Generalize select-with-unsatisfied-deps warning") makes the select-with-unsatisfied-dependencies warning trigger when a symbol with m-valued direct dependencies is y-selected. 2018-07-10T06:54:08Z Ulf Magnusson ulfalizer@gmail.com 2018-07-10T06:54:08Z urn:sha1:9ae09d5a5c6c69c089f76eb0b7ce3bbcb690257d Has been removed (and is now always on). 2018-07-10T05:56:37Z Ulf Magnusson ulfalizer@gmail.com 2018-07-03T16:30:06Z urn:sha1:2433deba7889931c4bae679f116887fe49a2ce04 Implement the Kconfig preprocessor described in https://github.com/torvalds/linux/blob/master/Documentation/kbuild/kconfig-macro-language.txt (which is now in linux-next and will appear in Linux 4.18). A new Kconfig.variables property holds all the preprocessor variables so that they can be inspected programmatically. Preprocessor variables are represented by a new Variable class. With the preprocessor, environment variables are referenced with $(FOO) instead of $FOO. For backwards compatibility, $FOO is accepted as well for now (and leaves "$FOO" as-is if FOO doesn't exist). The $FOO syntax might be dropped at some point in the future (together with a major version increase). It should be supported for a few months at least. Some internals were cleaned up too, mostly related to parsing. Some outdated documentation was fixed as well.
