first off, we add an oddly slow basic test of 10k item inventory
Before:
```
Ran 229 tests in 13.214s
OK
real 0m13.403s
user 0m12.106s
sys 0m1.155s
```
After:
```
Ran 230 tests in 21.328s
OK
real 0m21.516s
user 0m20.099s
sys 0m1.275s
```
since that seems like a bit long for the test to add to runtime, lets profile
`python -m cProfile -s time ./bin/ansible all -i test/units/inventory_test_data/huge_range --list-hosts`
Before:
```
1272607 function calls (1259689 primitive calls) in 8.497 seconds
Ordered by: internal time
ncalls tottime percall cumtime percall filename:lineno(function)
10000 4.393 0.000 4.396 0.000 __init__.py:395(_get_host)

10011 0.087 0.000 0.087 0.000 {posix.getcwd}
```
The top two lines are promising optimization targets
- populate Inventory's host cache more in _get_host, as we are looping
over all the groups anyways.
- eliminate duplicate check of whether we've already included a host
in the construction around __append_host_to_results we can infer
presence of a host in the results list implies the presence of its
name in the hostnames set, allowing us to only to the less expensive
of the two checks

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 http://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 decide to go with the development branch, be sure to run git submodule update --init --recursive after doing a checkout.
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
- irc.freenode.net: #ansible
Branch Info
- Releases are named after Van Halen songs.
- The devel branch corresponds to the release actively under development.
- As of 1.8, 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.
