Adrian Likins 7bd57acda4 Linux mount/fs (lsblk) facts fixes and tests. (#17036) ... Fixes #10779 Refactor some of the block device, mount point, and mtab/fstab facts collection for linux for better performance on systems with lots of block devices. Instead of invoking 'lsblk' for every entry in mtab, invoke it once, then map the results to mtab entries. Change the args used for invoking 'findmnt' since the previous combination of args conflicts, so this would always fail on some systems depending on version. Add test cases for facts Hardware()/Network()/Virtual() classes __new__ method and verify they create the proper subclass based on the platform.system() results. Split out all the 'invoke some command and grab it's output' bits related to linux mount paths into their own methods so it is easier to mock them in unit tests. Fix the DragonFly* classes that did not defined a 'platform' class attribute. This caused FreeBSD systems to potentially get the DragonFly* subclasses incorrectly. In practice it didnt matter much since the DragonFly* subclasses duplicated the FreeBSD ones. Actual DragonFly systems would end up with the generic Hardware() etc instead of the DragonFly* classes. Fix Hardware.__new__() on PY3, passing args to __new__ would cause "object() takes no parameters" errors. So check for PY3 and just call __new__ without the args See https://hg.python.org/cpython/file/44ed0cd3dc6d/Objects/typeobject.c#l2818 for some explaination.		2016-08-17 17:58:51 -07:00
