Fork of https://github.com/zephyrproject-rtos/Kconfiglib.git https://git.mcdonnell.dev/Kconfiglib.git/atom?h=v9.0.0 2018-07-15T14:15:43Z 2018-07-15T14:15:43Z Ulf Magnusson ulfalizer@gmail.com 2018-07-15T11:16:47Z urn:sha1:7a428aa415606820a44291f475248b08e3952c4b Instead of having 'source' and 'gsource', have 'source' always glob, but require the pattern to match at least one file, throwing KconfigError otherwise. Have separate 'osource' and 'orsource' statements (the o is for "optional") for cases where it's okay for the pattern to not match any files. This is analogous to 'include' and '-include' in Make. The biggest flaw with 'gsource' was that there was no way to do a globbing match while requiring something to match, possibly leading to subtle failures. Preserve backwards compatibility by having "gsource" and "grsource" be aliases for "osource" and "orsource", respectively. Also include some related changes: - Kconfig.srctree is now set to the empty string if $srctree is unset, rather than to None. This gives nice behavior with os.path.join() and os.path.relpath(), which treat the empty string as the current directory (without adding './', for os.path.join()). - When $srctree is set, Kconfig files in the current directory will no longer override Kconfig files in $srctree when the relative paths match. This was likely a bug all along in the C tools, and probably only makes sense for .config files. I've seen it cause breakage in Zephyr. - Clarify the behavior of $srctree in the Kconfig.__init__() docstring. - Make MenuNode.filename be relative to $srctree for the Kconfig file passed to Kconfig.__init__(). This makes it consistent. The major version will be bumped later due to the small Kconfig.srctree API change. 2018-07-15T10:41:53Z Ulf Magnusson ulfalizer@gmail.com 2018-07-15T10:41:41Z urn:sha1:d8a7421d231e504e5b1409d9ed3137b147b3db8d Bit easier to read. 2018-07-15T10:09:54Z Ulf Magnusson ulfalizer@gmail.com 2018-07-15T10:09:54Z urn:sha1:bae9b9ea7997efec0a8b9a68e43cc110125e40a8 Off-by-one error, though still functional. The recursive source is now detected immediately as the file is source'd the second time. Also remove an outdated comment re. KconfigError. 2018-07-13T16:22:12Z Ulf Magnusson ulfalizer@gmail.com 2018-07-13T16:22:12Z urn:sha1:ac692af07a123b3d623e51df7f1e7a10b88c1ddd When using gsource with $srctree set to an absolute path, the $srctree prefix would show up in MenuNode.filename, trickling its way into e.g. generated documentation. This was due to a broken test: os.path.isabs() was checked after joining the pattern with $srctree, making it mistake an absolute $srctree for an absolute path in the Kconfig file. Fix the test. 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 2018-07-10T12:41:43Z 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.

Would be nice if there was a trivial way to give the location(s). Just say "somewhere" for now. 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.
