From e3d66733712e161d9287ea3f0116e5b57477b0d8 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Damir=20Jeli=C4=87?= Date: Sun, 8 Jul 2018 12:19:16 +0200 Subject: python: Import improved python bindings. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit imports the python bindings from: https://github.com/poljar/python-olm The bindings are imported at commit c44b145818520d69eaaa350fb95afcb846125e0f Minor modifications were made while importing: - Removed travis config - Removed Arch Linux PKGBUILD - Removed the html docs, they can be rebuild by running make html in the docs folder - Slightly modified the README The new bindings feature some improvements over the old ones: - Python 2 and 3 support - Automatic memory management - Automatic memory clearing before it is freed - Type signatures via the python typing module - Full test coverage - Properties are utilized where it makes sense (e.g. account.id) Signed-off-by: Damir Jelić ---
