Kconfiglib.git, branch v10.1.0

Make 10.1.0 release

2018-08-22T22:55:16Z

New features: - Commit 7dae988 ("Add a generic node iterator") adds a Kconfig.node_iter() helper generator for iterating through all menu nodes in the menu tree, in definition order. Optionally, symbols defined in multiple locations are only generated once. This generator is now used internally by write_config() as well. Suggested by Mitja Horvat (pinkfluid). - Commit d2c1430 ("Introduce Kconfig.unique_defined_syms and Kconfig.unique_choices") adds versions of Kconfig.defined_syms/choices that only include symbols and choices defined in multiple locations once, while still preserving definition order. This is almost always what you want when iterating through (just) symbols and choices. It removes set() hackery (where it's easy to accidentally mess up the order) and the like. Fixes: - Commit 4ebc2aa ("Flag extra tokens after 'if'/'depends on'/'visible if' expressions") tightens up syntax checking so that extra trailing tokens after 'if', 'depends on', and 'visible if' expressions raise a syntax error, instead of being silently ignored. Oversight.

Flag extra tokens after 'if'/'depends on'/'visible if' expressions

2018-08-22T22:51:52Z

Extra trailing tokens after 'if ', 'depends on ', and 'visible if ' now trigger syntax errors instead of being ignored. Oversight. This indirectly makes Kconfig.eval_expr() detect extra trailing tokens as well.

Add a generic node iterator

2018-08-22T21:57:17Z

Suggested by Mitja Horvat (pinkfluid) in https://github.com/ulfalizer/Kconfiglib/pull/50. Kconfig.node_iter() iterates through all menu nodes in the menu tree in Kconfig order. This saves scripts the trouble of implementing their own tree walking code. Have node_iter() take a 'unique_syms' flag that can be enabled to only include symbols defined in multiple locations once. This is often what you want when generating output (and is used by write_config()). Order is still preserved. Piggyback a fix to a syntax error test comment. Parsing has been tightened up now.

Introduce Kconfig.unique_defined_syms and Kconfig.unique_choices

2018-08-22T18:05:11Z

These are the same as Kconfig.defined_syms and Kconfig.choices, except duplicates are removed. Kconfig order is still preserved. This is almost always what you want when iterating through symbols and choices, as it potentially saves work, avoids generating duplicates when writing output, and still preserves Kconfig order for readability. The old attributes will be kept for backwards compatibility (maybe there's some rare cases where they could be useful too). They're created internally anyway.

Merge Symbol._checked and Symbol._written

2018-08-21T19:17:45Z

These are never used at the same time, and Symbol._visited is a good name for both. Gets rid of an internal attribute.

Handle multiple definition locations in a nicer way

2018-08-21T18:45:27Z

Instead of precalculating a set() to get unique symbols, precalculate a list with any duplicates from multiple definition locations removed, and preserve the order of the symbols within it. This makes it possible to get rid of the Symbol._written shenanigans in functions that only need to iterate through unique symbols in sorted order, which is all of them except write_config() (because it needs to walk the entire menu tree).

Make auto.conf symbol order match .config symbol order

2018-08-21T14:36:28Z

Not likely that you'd need to inspect it, since it's more of an implementation detail of incremental builds, but it doesn't hurt.

Fix header/minimal configuration ordering test

2018-08-21T13:40:53Z

Should test write_autoconf(), not write_config().

Make 10.0.1 release

2018-08-21T13:19:52Z

Adds commit 7f3844f ("Make symbol order match between headers and .config files"), which fixes a bug introduced by commit 71872a8 ("Massively speed up U-Boot parsing"). The ordering of symbols in header files now matches the order in .config files again, which was always the intent. It makes things more readable, and is nice for version control too.

Make header symbol order match .config symbol order again

2018-08-21T13:19:52Z

I accidentally broke this when I added the _defined_syms_set optimization. No semantic difference, but having the order match is more readable.
