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.
Add HTML-escaping to code examples in rST tempate of module-formatter
Add support for specifying port, addresses with phrases and attaching files
Add support for custom headers and document version_added for new options
X-Mailer header added :)
protect empty address lists & attachment list, and add bcc
- Added username, password arguments.
- Documented existing revision argument.
- Corrected documentation/docstrings; removed git references, use svn
nomenclature, etc.
- Refactored duplicate code, redundant shell calls, filter abuse,
inconsistent formating, etc.
- Shell quoting so it doesn't break for one guy who has spaces in
pathnames.
- svn called with '--non-interactive' and '--no-auth-cache'.
Move operations that are dependant on a remote branch under a if
is_remote_branch() conditional. While at it, remove assignment to cmd
string in same block that wasn't used when calling _run().
The git module would not pull in updates to a branch when
version=<branch>. This updates that block to checkout the branch
and then do a git reset --hard <remote>/<branch>. This
should now track updates to a branch.
In a virtualenv, pip is called just pip. This fixes the pip module to
search for the virtualenv pip first before trying the pip-python and
python-pip variants. Without this, pip module would not install to the
virtualenv when that parameter is provided.
This updates _is_package_installed() to accept a requirements file
as an argument. This is used later in main() to check if python libs
specified in a requirements file are already installed. I updated
main() to consolidate the handling of install/uninstall in a single
block. This should help if someone wants to remove packages specified
by a requirements file.
This makes the line parsing a lot more robust (and easier to read).
Code supplied by @dhozac, thanks!
Remove re import because this is not used anywhere.
When trying to perform enabled=yes followed by enabled=no
against FreeBSD the module would die with the following error:
TypeError: sub() takes at most 4 arguments (5 given)
The target FreeBSD client (8.2) is running python 2.6.6. It seems the
extra 'flags' argument was added to re.sub() in 2.7.
In fixing this issue I have attempted to create a general atomic method
for modifying a rc.conf file. Hopefully this will make it easier to add
other rc based platorms. The strip/split magic was inspired by the user
module.
* Basically the moving parts from the original service module arranged in
subclasses.
* General structure and helper methods comes from the user module.
* Less forgiving to unsupported platforms: it requires a subclass per platform.
(This makes it easier to work on one platform without having to think about.
what other platform might be affected in unexpected ways).
* Now has basic OpenBSD support.
* Solaris support needs to be added.
Thanks to @dhozac for general advice and Linux testing.
Thanks to @bcoca for clearing up some FreeBSD questions.
I added all known virtualization types from the virt-what project. However, the few virt types that rely on cpuid information have not been implemented lacking native python cpuid access. (hyperv)
Without this fix, generating documentation results in:
```

- Make sure exit_json() always returns a changed= value
- Modify the yum module to not return failed=False
- Modify install() and latest() similar to remove() in yum module
- Changed exit_json(failed=True, **res) into a fail_json(**res)
- Make sure yum rc= value reflects loop (similar to how we fixed remove())
Rewrote switch_version() to read .git/HEAD to find branch associated
with HEAD. If in a detached HEAD state, will read
.git/refs/remotes/<remote>/HEAD.
Rename pull() to fetch(). It does a git fetch and then a
git fetch --tags.
Add _run() method to handle all subprocess.Popen calls. Change
all previous calls to subprocess.Popen to use _run().
There is no need to require thirsty mode when the destination is a directory. We add the basename of the url to the destination directory and proceed with that. If that file exists in non-thirsty mode continue as expected.
I also cleaned up some of the logic that is no longer necessary if we simply rewrite the destination from the very start the way it is expected.
I had made and pushed this change after you already pulled the request.
@dhozac indicated that it would probably be better to use return codes > 255 for anything related to Ansible itself. Which makes sens :)
We use the lineinfile module to modify configuration files of a proprietary application. This application reads configuration options from files, but does not require those files to exist (if the default options are fine). However this application may modify the configuration file at will, so we cannot copy or template those files. And after a silent install the configuration may not exist (depending on the response file).
Whatever the case, during deployment we need to make sure some configuration options are set after the installation.
So the cleanest way to handle this situation is to allow the lineinfile module to create the file if it is missing (and this is the expected behavior). When I proposed this behavior, @sergevanginderachter needed the same functionality and was now working around it as well.
