Kconfiglib.git, branch v11.9.0

Make 11.9.0 release

2019-05-31T00:16:52Z

Adds commit 175c1f5 ("Leave unchanged output files untouched"). This avoids updating file modification timestamps when nothing has changed, which can make it easier to avoid triggering redundant rebuilds.

Remove some 'Note:'s, update some stuff.

Leave unchanged output files untouched

2019-05-30T22:08:14Z

Before writing a configuration file or header file, compare the old contents of the file against the new contents. If there's no change, skip the write, to avoid updating the file modification time. This might avoid triggering redundant rebuilds depending on how the build system is set up, and could allow for a simpler setup.

Make 11.8.0 release

2019-05-29T00:50:48Z

Adds commit 437c6cc ("Use os.replace() if available in _save_old()"), which gives rename() semantics on Windows, avoiding copying the file. This was cherry-picked out of a larger change re. avoiding touching files whose contents haven't changed. Will come later.

Split out helper for writing symbols in write_config()

2019-05-29T00:47:59Z

Gives a better overview.

Use os.replace() if available in _save_old()

2019-05-29T00:47:44Z

Gives *nix rename() semantics on Windows, with overwriting of the target file. Also limit the scope of the catch-all try-except.

Convert docstrings to comments in testsuite.py

2019-05-29T00:47:44Z

Like was done a long time ago in kconfiglib.py. These functions are not part of a standalone API. Keep the docstrings for the compatibility tests, because those get printed as the tests run.

Make 11.7.0 release

2019-05-28T15:10:25Z

Adds commit 3aea9f7 ("Add '# end of ' after menus in .config"), which mirrors a change in the C tools. The compatibility tests now pass again for the latest kernel.

Explain why node_iter() is not a good fit for write_config()

2019-05-28T15:09:09Z

Add '# end of ' after menus in .config

2019-05-28T15:00:24Z

Mirrors commit aff11cd983ec ("kconfig: Terminate menu blocks with a comment in the generated config") in the kernel. This makes the compatibility tests pass again, and is handy.
