Kconfiglib.git, branch v10.31.0

Make 10.31.0 release

2018-12-08T02:30:05Z

Adds two improvements related to configuration files: - Commit 166be7d ("Save existing configuration to ..old in write_config()") - Commit 7b4f72f ("Make {load,write}_config(filename=None) implement the standard behavior")

Make {load,write}_config(filename=None) implement the standard behavior

2018-12-08T02:28:52Z

Make the previously obligatory 'filename' argument to load_config() and write_config() default to None, and have that implement the behavior you'd usually want: read/write either KCONFIG_CONFIG or ".config" if unset, and read the 'option defconfig_list' configuration file if KCONFIG_CONFIG/".config" doesn't exist. For load_config(), filename=None also allows the configuration file to be missing without raising an error. load_config() returns True if a local configuration file was loaded, which is useful to check in the menuconfig (if no local configuration file exists, we always want to prompt for saving the configuration when exiting). Also add a 'verbose' argument (default True) to load_config() and read_config() that makes them print which files were read/written in filename=None mode. Also generalize olddefconfig.py and oldconfig.py to not require there to already be a local configuration file. This was a bit silly for olddefconfig.py in particular. Remove the examples/defconfig.py script. It's a duplicate of olddefconfig.py.

Save existing configuration to ..old in write_config()

2018-12-07T23:14:42Z

Add a default-True 'save_old' flag to write_config(). If 'save_old' is True and an existing configuration file is being overwritten, a copy of the old configuration file is saved to ..old (e.g. .config.old) in the same directory. Errors are ignored, as the old configuration would usually just be a nice-to-have, and not essential. The same functionality could be added for minimal configuration files and headers, but it's probably most useful for configuration files.

menuconfig: Code formatting nit

2018-12-07T21:51:13Z

Rename 'val_sym' to 'sym' in str_value()

2018-12-07T21:48:50Z

Consistent with elsewhere.

Remove _internal_error()

2018-12-07T21:45:09Z

These type sanity checks have never hit once during development over the years, and were inconsistently applied too. Remove them to simplify the code. Keep the InternalError exception for backwards compatibility, in case something catches it.

Make 10.30.0 release

2018-12-01T16:30:17Z

Adds a small incremental building improvement: commit a4751b5 ("Flag removed symbols as changed in sync_deps()")

Flag removed symbols as changed in sync_deps()

2018-12-01T16:29:29Z

If a symbol is removed from a Kconfig file, it makes sense to flag it as changed, so that things that still (probably accidentally) depend on it get rebuilt. Saw a patch for the C tools with the same effect floating around, so might as well add it already. The C tools had other brokeness as well though...

Make 10.29.0 release

2018-12-01T13:17:38Z

Adds commit 567cccf ("Tighten up help text parsing"), which improves parsing performance slightly.

Tighten up help text parsing

2018-12-01T13:17:38Z

Get rid of _indentation() and inline it into _parse_help(), adding some simplifications and optimizations along the way. Saves a few % of parsing of time. Help text parsing is surprisingly hot.
