2.0.0

Release 2.0.0

The surface functionality hasn't changed much but a few bugs have been fixed. Under the hood, a lot has changed. Functionality has now been moved into a class that helped with value tracking. I planned on removing Python 2 support but was convinced to leave it in for now as apparently there are still a lot of python2 users. 😕 🤷‍♂️

Most testing has moved to occur underneath tox, this is superior as it provides for testing in a clean environment and an installed environment.

Merges

• #22, #24, #25 by @abompard
• #21 by @spaceone and @LaurieReeves
• #16 by @okin
• #14 by @codypiersall
• #11 by @e4r7hbug and @hugovk
• #5 by @willmo
• #4 by @skylize
• #3 by @fatlotus

Bugs fixed

• Documentation in the README.md is updated, the new method of authentication is pam.authenticate(...) vs. pam.pam(...) (but it's still supported). Thank you @gkmcd. Some by-hand pam_unix.so and unix_chkpwd examples provided for testing
• @leewi9 pointed out that TTY handling was less than optimal in some situations in #18
• #12 resolved by @okin and #8 was also solved by this patch

Features & Changes

• Unit testing and code coverage is 100% for all automated methods. Some methods require a valid TEST_USERNAME and TEST_PASSWORD to function and those are marked SKIP if not found in the environment. Sorry :-} -- mocking the internals of libc and libpam are far too hairy for the trivial bit of testing that can be verified by hand
