Fix absolute $srctree prefixes showing up on gsource'd files

2018-07-13T16:22:12Z

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.

Warn if int/hex 'default' is outside active 'range'

2018-07-10T12:19:04Z

Only out-of-range user values generated warnings before. The C tools warn for neither of them.

Add Kconfig preprocessor

2018-07-10T05:56:37Z

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 Some outdated documentation was fixed as well.

Refactor tokenization a bit

2018-07-02T02:36:17Z

Have _tokenize() take the string to tokenize and return a list of tokens, and handle all the token list management outside. Simplifies the internal logic a bit. Likely faster too.

Turn MenuNode/Symbol/Choice.referenced() into a @property

2018-06-22T04:02:47Z

Having it as a function is inconsistent, since all other read-only fields use properties. Oversight. Major version will be bumped to 7, though the function version wasn't in for long.

Add Symbol/Choice.referenced() convenience methods

2018-06-22T04:02:47Z

Returns the union of the MenuNode.referenced() sets for all the menu nodes of the symbol/choice.

Rename KconfigSyntaxError to KconfigError

2018-06-19T22:16:16Z

This exception is generated for semantic errors and e.g. when dependency loops are detected as well, so the name is bad. Keep the old name as an alias for now for backwards compatibility.

Add dependency loop detection

2018-06-19T20:14:09Z

Pretty long overdue. Until now, dependency loops have raised a hard-to-debug Python RecursionError during evaluation. A Kconfiglib exception is raised now instead, with a message that lists all the items in the loop. See the comment at the start of _check_dep_loop_sym() for an overview of the algorithm. At a high level, it's loop detection in a directed graph by keeping track of unvisited/visited nodes during depth-first search. (A third "visited, known to not be in a dependency loop" state is used as well.) Choices complicate things, as they're inherently loopy: The choice depends on the choice symbols and vice versa, and the choice symbols in a sense all depend on each other. Add the choice-to-choice-symbol dependencies separately after dependency loop detection, so that there's just the choice-symbol-to-choice dependencies to deal with. It simplifies things, as it makes it possible to tell dependencies from 'prompt' and 'default' conditions on the choice from choice symbol dependencies. Do some flag shenanigans to prevent the choice from being "re-entered" while looping through the choice symbols. Maybe this could be cleaned up a bit somehow... Example exception message: Dependency loop =============== A (defined at tests/Kdeploop10:1), with definition... config A bool depends on B ...depends on B (defined at tests/Kdeploop10:5), with definition... config B bool depends on C = 7 ...depends on C (defined at tests/Kdeploop10:9), with definition... config C int range D 8 ...depends on D (defined at tests/Kdeploop10:13), with definition... config D int default 3 if E default 8 ...depends on E (defined at tests/Kdeploop10:18), with definition... config E bool (select-related dependencies: F && G) ...depends on G (defined at tests/Kdeploop10:25), with definition... config G bool depends on H ...depends on the choice symbol H (defined at tests/Kdeploop10:32), with definition... config H bool prompt "H" if I && depends on I && ...depends on the choice symbol I (defined at tests/Kdeploop10:41), with definition... config I bool prompt "I" if depends on ...depends on (defined at tests/Kdeploop10:38), with definition... choice bool prompt "choice" if J ...depends on J (defined at tests/Kdeploop10:46), with definition... config J bool depends on A ...depends again on A (defined at tests/Kdeploop10:1)

Test property ordering on nested multi.def. choices

This case wasn't covered.

Fix MenuNode.referenced() on Kconfig.top_node

2018-06-14T16:42:01Z

The property lists weren't created for Kconfig.top_node, making referenced() crash. Add a MenuNode constructor and create the property lists there instead of in _parse_properties().
