Ansible Changes By Release

0.7 "Panama" -- release pending -- I can barely see the roadmap from the heat coming off of it.

Module changes:

• login_unix_socket option for mysql user and database modules (see PR #781 for doc notes)
• new modules -- pip, easy_install, apt_repository, supervisorctl
• error handling for setup module when SELinux is in a weird state
• misc yum module fixes
• better changed=True/False detection in user module on older Linux distros
• nicer errors from modules when arguments are not key=value
• backup option on copy (backup=yes)
• file module will not recurse on directory properties
• yum module now workable without having repoquery installed, but doesn't support comparisons or list= if so
• setup module now detects interfaces with aliases
• better handling of VM guest type detection in setup module
• new module boilerplate code to check for mutually required arguments, arguments required together, exclusive args
• add pattern= as a paramter to the service module (for init scripts that don't do status, or do poor status)
• various fixes to mysql & postresql modules

Core changes:

• ansible --version will now give branch/SHA information if running from git
• better sudo permissions when encountering different umasks
• when using paramiko and SFTP is not accessible, do not traceback, but return a nice human readable msg
• use -vvv for extreme debug levels. -v gives more playbook output as before
• -vv shows module arguments to all module calls (and maybe some other things later)
• don't pass "--" to sudo to work on older EL5
• make remote_md5 internal function work with non-bash shells
• allow user to be passed in via --extra-vars (regression)
• add --limit option, which can be used to further confine the pattern given in ansible-playbooks
• adds ranged patterns like dbservers[0-49] for usage with patterns or --limit
• -u and user: defaults to current user, rather than root, override as before
• /etc/ansible/ansible.cfg and ~/ansible.cfg now available to set default values and other things
• (developers) ANSIBLE_KEEP_REMOTE_FILES=1 can be used in debugging (envrionment variable)
• (developers) connection types are now plugins
• (developers) callbacks can now be extended via plugins

Playbooks:

• YAML syntax errors detected and show where the problem is
• if you ctrl+c a playbook it won't traceback (usually)
• vars_prompt now has encryption options (see examples/playbooks/prompts.yml)
• allow variables in parameterized task include parameters (regression)
• add ability to store the result of any command in a register (see examples/playbooks/register_logic.yml)
• --list-hosts to show what hosts are included in each play of a playbook
• fix a variable ordering issue that could affect vars_files with selective file source lists
• adds 'delegate_to' for a task, which can be used to signal outage windows and load balancers on behalf of hosts
• adds 'serial' to playbook, allowing you to specify how many hosts can be processing a playbook at one time (default 0=all)

0.6 "Cabo" -- August 6, 2012

playbooks:

• support to tag tasks and includes and use --tags in playbook CLI
• playbooks can now include other playbooks (example/playbooks/nested_playbooks.yml)
• vars_files now usable with with_items, provided file paths don't contain host specific facts
• error reporting if with_items value is unbound
• with_items no longer creates lots of tasks, creates one task that makes multiple calls
• can use host_specific facts inside with_items (see above)
• at the top level of a playbook, set 'gather_facts: False' to skip fact gathering
• first_available_file and with_items used together will now raise an error
• to catch typos, like 'var' for 'vars', playbooks and tasks now yell on invalid parameters
• automatically load (directory_of_inventory_file)/group_vars/groupname and /host_vars/hostname in vars_files
• playbook is now colorized, set ANSIBLE_NOCOLOR=1 if you do not like this, does not colorize if not a TTY
• hostvars now preserved between plays (regression in 0.5 from 0.4), useful for sharing vars in multinode configs
• ignore_errors: True on a task can be used to allow a task to fail and not stop the play
• with_items with the apt/yum module will install/remove/update everything in a single command

inventory:

• groups variable available as a hash to return the hosts in each group name
• in YAML inventory, hosts can list their groups in inverted order now also (see tests/yaml_hosts)
• YAML inventory is deprecated and will be removed in 0.7
• ec2 inventory script
• support ranges of hosts in the host file, like www[001-100].example.com (supports leading zeros and also not)

modules:

• fetch module now does not fail a system when requesting file paths (ex: logs) that don't exist
• apt module now takes an optional install-recommends=yes|no (default yes)
• fixes to the return codes of the copy module
• copy module takes a remote md5sum to avoid large file transfer
• various user and group module fixes (error handling, etc)
• apt module now takes an optional force parameter
• slightly better psychic service status handling for the service module
• fetch module fixes for SSH connection type
• modules now consistently all take yes/no for boolean parameters (and DWIM on true/false/1/0/y/n/etc)
• setup module no longer saves to disk, template module now only used in playbooks
• setup module no longer needs to run twice per playbook
• apt module now passes DEBIAN_FRONTEND=noninteractive
• mount module (manages active mounts + fstab)
• setup module fixes if no ipv6 support
• internals: template in common module boilerplate, also causes less SSH operations when used
• git module fixes
• setup module overhaul, more modular
• minor caching logic added to inventory to reduce hammering of inventory scripts.
• MySQL and PostgreSQL modules for user and db management
• vars_prompt now supports private password entry (see examples/playbooks/prompts.yml)
• yum module modified to be more tolerant of plugins spewing random console messages (ex: RHN)

internals:

• when sudoing to root, still use /etc/ansible/setup as the metadata path, as if root
• paramiko is now only imported if needed when running from source checkout
• cowsay support on Ubuntu
• various ssh connection fixes for old Ubuntu clients
• ./hacking/test-module now supports options like ansible takes and has a debugger mode
• sudoing to a user other than root now works more seamlessly (uses /tmp, avoids umask issues)

0.5 "Amsterdam" ------- July 04, 2012

0.4 "Unchained" ------- May 23, 2012

Internals/Core

• internal inventory API now more object oriented, parsers decoupled
• async handling improvements
• misc fixes for running ansible on OS X (overlord only)
• sudo improvements, now works much more smoothly
• sudo to a particular user with -U/--sudo-user, or using 'sudo_user: foo' in a playbook
• --private-key CLI option to work with pem files

Inventory

• can use -i host1,host2,host3:port to specify hosts not in inventory (replaces --override-hosts)
• ansible INI style format can do groups of groups [groupname:children] and group vars [groupname:vars]
• groups and users module takes an optional system=yes|no on creation (default no)
• list of hosts in playbooks can be expressed as a YAML list in addition to ; delimited

Playbooks

• variables can be replaced like ${foo.nested_hash_key.nested_subkey[array_index]}
• unicode now ok in templates (assumes utf8)
• able to pass host specifier or group name in to "hosts:" with --extra-vars
• ansible-pull script and example playbook (extreme scaling, remediation)
