Fix for persistent connection plugin on Python3. Note that fixes are also needed to each terminal plugin. This PR only fixes the ios terminal (as proof that this approach is workable.) Future PRs can address the other terminal types. * On Python3, pickle needs to work with byte strings, not text strings. * Set the pickle protocol version to 0 because we're using a pty to feed data to the connection plugin. A pty can't have control characters. So we have to send ascii only. That means only using protocol=0 for pickling the data. * ansible-connection isn't being used with py3 in the bug but it needs several changes to work with python3. * In python3, closing the pty too early causes no data to be sent. So leave stdin open until after we finish with the ansible-connection process. * Fix typo using traceback.format_exc() * Cleanup unnecessary StringIO, BytesIO, and to_bytes calls * Modify the network_cli and terminal plugins for py3 compat. Lots of mixing of text and byte strings that needs to be straightened out to be compatible with python3 * Documentation for the bytes<=>text strategy for terminal plugins * Update unittests for more bytes-oriented internals Fixes #24355 |

Ansible
Ansible is a radically simple IT automation system. It handles configuration-management, application deployment, cloud provisioning, ad-hoc task-execution, and multinode orchestration - including trivializing things like zero downtime rolling updates with load balancers.
Read the documentation and more at https://ansible.com/
Many users run straight from the development branch (it's generally fine to do so), but you might also wish to consume a release.
You can find instructions here for a variety of platforms.
If you want to download a tarball of a release, go to releases.ansible.com, though most users use yum (using the EPEL instructions linked above), apt (using the PPA instructions linked above), or pip install ansible.
Design Principles
- Have a dead simple setup process and a minimal learning curve
- Manage machines very quickly and in parallel
- Avoid custom-agents and additional open ports, be agentless by leveraging the existing SSH daemon
- Describe infrastructure in a language that is both machine and human friendly
- Focus on security and easy auditability/review/rewriting of content
- Manage new remote machines instantly, without bootstrapping any software
- Allow module development in any dynamic language, not just Python
- Be usable as non-root
- Be the easiest IT automation system to use, ever.
Get Involved
- Read Community Information for all kinds of ways to contribute to and interact with the project, including mailing list information and how to submit bug reports and code to Ansible.
- All code submissions are done through pull requests. Take care to make sure no merge commits are in the submission, and use
git rebasevsgit mergefor this reason. If submitting a large code change (other than modules), it's probably a good idea to join ansible-devel and talk about what you would like to do or add first and to avoid duplicate efforts. This not only helps everyone know what's going on, it also helps save time and effort if we decide some changes are needed. - Users list: ansible-project
- Development list: ansible-devel
- Announcement list: ansible-announce - read only

Branch Info
- Releases are named after Led Zeppelin songs. (Releases prior to 2.0 were named after Van Halen songs.)
- The devel branch corresponds to the release actively under development.
- For releases 1.8 - 2.2, modules are kept in different repos, you'll want to follow core and extras
- Various release-X.Y branches exist for previous releases.
- We'd love to have your contributions, read Community Information for notes on how to get started.
