* improves error handling and reporting
* uses run_command to reduce code
* fails quicker on errors as opposed to return codes and tracebacks
* can now also specify the key as data versus needing to wget it from a file
To be consistent with the table showing available options, use
underscores in the example tasks, not hyphens, as the table doesn't
list hyphenated versions of option names, so it looks like the
examples could have typos in them.
If a relative path is passed as an argument, this change first
converts it to an absolute path.
This fixes a bug where the git module would attempt to chdir into an
invalid directory because of multiple chdir calls against a relative
path.
pkgin always returns 0 so can't be used to tell if the install or remove
worked. Instead this just queries the installed packages after
performing an operation.
This adds two dependencies to the apt_repository module: apt and
apt_pkg. These come from the package python-apt. This is used to parse
the host's sources.list and examine whether the repo is already
configured. This then eliminates the unnecessary
'add-apt-repository --remove' from running.
- use boto instead of euca2ools
- improve error handling/propagation for run failures
- rename keypair to key_name (and preserve alias for old playbooks)
- should be 100% backward compatible with the euca2ools version
This adds "69" to the return codes from the status command that should be
considered as not running. At least "django-celery" uses this return code,
maybe others::
/venv/bin/python /code/project/manage.py celeryctl status
echo $? # 69 when not running.
A bit of googling let me to http://tldp.org/LDP/abs/html/exitcodes.html and
on a Ubuntu Server 12.10 I get::
~# cat /usr/include/sysexits.h | grep 69
#define EX_UNAVAILABLE 69 /* service unavailable */
I'm not sure if the content of sysexits.h is the same on other OS'es.
Pretty straightforward. Give it a URL with an exported GPG key for signing an
Apt repository. It downloads it and will install it using apt-key. It's even
smart enough to tell if it's already there (i.e. actually tells you if it
changed or not).
* Rename fail_on_rc_non_zero to check_rc, much more succinct.
* Simplify method defintion
* Fix command module and drop shell=shell option; whether to use
shell is determined by if args is a list.
This updates apt, apt_repository, command, cron, easy_install, facter,
fireball, git, group, mount, ohai, pip, service, setup, subversion,
supervisorctl, svr4pkg, user, and yum to take advantage of run_command
in module_common.py.
Without read permission to the current working directory, git-clone will
fail:
root@host:~$ sudo -u git -H git clone \
git://github.com/ansible/ansible.git /home/git/ansible
fatal: Could not change back to '/root': Permission denied
This commit ensures that the working directory is changed to the
parent-folder of the destination before doing the clone.
Two problems here
* unchecked exception handling and erroneous assumption as to why
an exception might fire
* although the file module expands the path, when using file_args
the unexpanded path is passed.
Expected result: ~/path/to/file should work fine
Actual result: exception is because it doesn't find file with a message
about not being able to get the selinux context
Added two additional template variables
* template_fullpath - absolute path to the template
* template_run_date - date that the template was rendered
Documented these additional variables in the module documentation
Since we use 'raw' heavily on equipment where 'command' and 'shell' are not (yet) working (and python may need to be installed first using raw) these improvements are necessary in order to write more complex scripts (with return code handling and separated stdout/stderr).
This change includes the following changes:
- exec_command() now returns the return code of the command
- _low_level_exec_command() now returns a dict, including 'rc', 'stdout' and 'stderr'
- all users of the above interfaces have been improved to make use of the above changes
- all connection plugins have been modified to return rc and stderr
- fix the newline problem (stdout and stderr would have excess newlines)
In a future commit I intend to add assertions or error handling code to verify the return code in those places where it wasn't done. Since only the output was available, the return code was ignored, even though we expect them to be 0.
Three changes:
* Add set_default_selinux_context() to module_common that sets
a file's context according to the defaults in the policy
* In atomic_replace(), set the default context for the file if
selinux is enabled and the destination file does not exist.
* In authorized_key, set the default context when creating
$HOME/.ssh and $HOME/.ssh/authorized_keys. If these already
exist, this won't touch them.
- Do not silently ignore malformed pip requirements files.
- Properly reports changed when removing packages.
- "latest" i.e. --upgrade is *not* incompatible with requirements files.
- Less branchy, simpler logic.
- Removed pointless variable "initializations", Python doesn't need that.
Other code simplifications.
- Fun fact; pip install is (kind of) case insensitive, pip freeze is not.
So, 'sqlalchemy' will be reported as installed by install, but missing
by freeze.
The perhaps controversial change and the one that led to finding /
fixing above issues...
Instead of adding command parameters 'index', and 'find', and 'mirrors',
and etc. Added 'extra_args' which are passed onto pip.
The use case for --index-url is having a private pypi repo, like
http://pypi.python.org/pypi/localshop, to which you publish private
packages. I'm sure most every pip option has a use case for someone.
extra_args handles all those. Can reserve ansible command parameters for
the most common.
Tested with pip 1.1.
