* Symbolic modes with X or =[ugo] always use original mode (Fixes #80128) Here's what's happening, by way of this mode example: u=,u=rX At the first step in the loop, the "u" bits of are set to 0. On the next step in the loop, the current stat of the filesystem object is used to determine X, not the "new_mode" in the previous iteration of the loop. So while most operations kind of operate left to right, "X" is always going back to the original file to determine whether to set x bit. The Linux "chmod" (the only one I've tested) doesn't operate this way. In it, "X" operates on the current state the loop understands it is in, based on previous operations (and starting with the file permissions). This is an issue with "X" and any of the "=[ugo]" settings, because they are lookups. For example, if a file is 755 and you do "ug=rx,o=u", file module produces 0557 and chmod produces 0555. This really becomes a problem when you want to recursively change a directory of files, and the files are currently 755, but you want to change the directory to 750 and the files to 640. In chmod you can do "a=,ug=rX,u+w" (or "a=,u=rwX,g=rX"), and have it apply equally to the directory and the files. I can't come up with a single way in the ansible file module to deterministically, recursively, set a directory to 750 and the contents to 640 no matter what the current permissions are, as the code currently is. The fix is to pass in "new_mode" to _get_octal_mode_from_symbolic_perms in lib/ansible/module_utils/basic.py inside _symbolic_mode_to_octal. And then take "new_mode" as an argument and use it instead of the filesystem object stat.st_mode value. * Fixing my new unit test, fixing bug in test comments |

It handles configuration management, application deployment, cloud provisioning, ad-hoc task execution, network automation, and multi-node orchestration. Ansible makes complex changes like zero-downtime rolling updates with load balancers easy. More information on the Ansible `website <https://ansible.com/>`_. Design Principles ================= * Have an extremely simple setup process with a minimal learning curve. * Manage machines 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. Use Ansible =========== You can install a released version of Ansible with ``pip`` or a package manager. See our `installation guide <https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html>`_ for details on installing Ansible on a variety of platforms. Power users and developers can run the ``devel`` branch, which has the latest features and fixes, directly. Although it is reasonably stable, you are more likely to encounter breaking changes when running the ``devel`` branch. We recommend getting involved in the Ansible community if you want to run the ``devel`` branch. Get Involved ============ * Read `Community Information <https://docs.ansible.com/ansible/latest/community>`_ 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. * Join a `Working Group <https://github.com/ansible/community/wiki>`_, an organized community devoted to a specific technology domain or platform. * Submit a proposed code update through a pull request to the ``devel`` branch. * Talk to us before making larger changes to avoid duplicate efforts. This not only helps everyone know what is going on, but it also helps save time and effort if we decide some changes are needed. * For a list of email lists, IRC channels and Working Groups, see the `Communication page <https://docs.ansible.com/ansible/latest/community/communication.html>`_ Coding Guidelines ================= We document our Coding Guidelines in the `Developer Guide <https://docs.ansible.com/ansible/devel/dev_guide/>`_. We particularly suggest you review: * `Contributing your module to Ansible <https://docs.ansible.com/ansible/devel/dev_guide/developing_modules_checklist.html>`_ * `Conventions, tips, and pitfalls <https://docs.ansible.com/ansible/devel/dev_guide/developing_modules_best_practices.html>`_ Branch Info =========== * The ``devel`` branch corresponds to the release actively under development. * The ``stable-2.X`` branches correspond to stable releases. * Create a branch based on ``devel`` and set up a `dev environment <https://docs.ansible.com/ansible/latest/dev_guide/developing_modules_general.html#common-environment-setup>`_ if you want to open a PR. * See the `Ansible release and maintenance <https://docs.ansible.com/ansible/devel/reference_appendices/release_and_maintenance.html>`_ page for information about active branches. Roadmap ======= Based on team and community feedback, an initial roadmap will be published for a major or minor version (ex: 2.7, 2.8). The `Ansible Roadmap page <https://docs.ansible.com/ansible/devel/roadmap/>`_ details what is planned and how to influence the roadmap. Authors ======= Ansible was created by `Michael DeHaan <https://github.com/mpdehaan>`_ and has contributions from over 5000 users (and growing).
