The check for the destination being a directory is now done before
checking if the file exists, that way the user is informed that the
thirsty argument is required.
If I create a database from scratch and assign permissions by doing:
- name: ensure database is created
action: postgresql_db db=$dbname
- name: ensure django user has access
action: postgresql_user db=$dbname user=$dbuser priv=ALL password=$dbpassword
Then it fails with the error:

This fix fixes the problem by not executing the regex if the
db query on pg_database returns None.
The use-case here is that based on information in the /proc/cmdline certain actions can be taken.
A practical example in our case is that we have a play at the end of the provisioning phase that reboots the system. Since we don't want to accidentally reboot a system (or restart the network) on a production machine, having a way to separate an Anaconda post-install (sshd in chroot) with a normal system is a good way to make that distinction.
---
- name: reboot
hosts: all
tasks:
- action: command init 6
only_if: "not '${ansible_cmdline.BOOT_IMAGE}'.startswith('$')"
A practical problem here is the fact that we cannot simply check whether it is set or empty:
---
- name: reboot
hosts: all
tasks:
- action: command init 6
only_if: "'${ansible_cmdline.BOOT_IMAGE}'"
If ansible_cmdline was a string, a simple only_if: "'${ansible_cmdline}'.find(' BOOT_IMAGE=')" was an option, but still not very "beautiful" :-/
This implementation uses shlex.split() and uses split(sep, maxsplit=1).
This allows the use of ~ in the chdir argument of the command module
I know the later change is absolutely necessary as the first change
was not sufficient. It may be that the first change fixes shell and
the second fixes command.
Added required as optional argument to get_bin_path(). It defaults to
false. Updated following modules to use required=True when calling
get_bin_path(): apt_repository, easy_install, group, pip,
supervisorctl, and user.
Also removed _find_supervisorctl() from supervisorctl module and updated
_is_running() to not need it.
Will manage values of seboolean on a host. Options are name (name of
boolean), state (on or off), and persistent (on or off). Persistent
defaults to no.
* Migraed easy_install, pip, service, setup, and user.
* Updated fail_json message in apt_repository
* Fixed easy_install to not hardcode location of virtualenv in
/usr/local/bin/.
* Made handling of virtualenv more consistent between easy_install and
pip.
Most of it worked already, except for the enable parameter, because it
tried to use chkconfig which only sees SysV services. First look for
systemctl and use that if it exists.
This takes started, stopped and restarted.
Started returns when connecting is possible.
Stopped when connecting is not possible.
Restarted first waits for connecting to be impossible and returns when it is
possible again.
Use a different method to query for current
privileges at the table and database level.
This method is more robust if newer privileges
are added in future versions and also supports the
ALL wildcard.
fail_on_user option can be used to ignore silently
if the user cannot be removed because of remaining
privilege dependencies to other objects in the
database. By default it will fail, so that this new
behavior won't surprise unsuspecting users.
The postgresql_user module has several drawbacks:
* No granularity for privileges
* PostgreSQL semantics force working on one
database at time, at least for Tables. Which
means that a single call can't remove all the
privileges for a user, and a user can't be
removed until all the privileges are removed,
forcing a module failure with no way to
work around the issue.
Changes:
* Added the ability to specify granular privileges
for database and tables within the database
* Report if user was removed, and add an option to
disable failing if user is not removed.
whether to download it every time or not -- will replace only on change, or decide to not download. The default
is thirsty=no which will not download every time by default.
mpdehaan requested in ansible/ansible#795 that globals be removed.
The response was to remove the lines with the word 'global', but not
the actual use of global variables. Which makes the module break silently.
Updated to use local variables.
When initalizing a connection to psycopg2, in order to use the default
values, the keywords must be missing. So we use a dictionary as a kwarg
and include only the keywords that do not have an empty value on the
module parameters.
it is possible those folks w/o yum-utils installed but with rhn-plugin
installed but w/o any rhn-certificates will still see an error msg.
they have 3 options:
1. remove rhn-plugin
2. enable some channels w/rhn certs
3. install yum-utils
If ip is not found in either /sbin or /usr/sbin, this will return
an empty result. It seems extremely unlikely that a linux system will
not have iproute2 installed
This updates set_owner_if_different() and set_group_if_different()
to not implicitly recurse when setting ownership (whether user or
group). It drops the os.system() call and replaces it with os.chown().
Resolves issue #825.
The recursion should be explicit. A recurse=yes|no option should be
added to the file module.
This adds user_password() to abstract how the user's password is looked
up. If spwd is not available, this will read the shadow file for the
user's shadow entry. This will then facilitate idempotent password
changes on hosts without spwd.
git module used to check stderr for the string 'error' after calling
switch_version(). This changes that to just look at the return code to
determine whether the command failed. If the rc is not zero, the git
module will call fail_json().
The problem is that git checkout will summarize the commit message,
such as:
HEAD is now at ea38409... removing artificial error
When the string 'error' is the commit message, this check will
erroneously think the command failed.
This also removes the method switchLocalBranch() since it is no longer
used.
operations in the correct order, so the file module results overlay the original module results, not the other way
around (which keeps any failure msg's intact)
Although library/copy can be corrected to understand that dest is
a directory, I can't see how to let _execute_copy know this and let the
file module know.
As a better solution than before #733, the copy module now explicitly (rather
than silently) fails when dest is a directory.
Allow use of service module with just enable parameter, per issue #755.
Also fixed two other issues:
- fixed parameter to be 'enabled' per docs, not 'enable'.
- fixed if block that checks whether to run _do_enable() to check
whether the parameter is set, not the value of the enable value which
may be None or False. If enabled=no, the service would never be
disabled.
Convert git module to module magic.
Drop cruft no longer needed.
Standardize indent to 4 spaces in methods switchLocalBranch, reset,
clone, and get_version.
Update is_local_branch to also handle '* branch' format.
Add is_current branch method()
Update pull() method to use is_current_branch()
passwd -> password
loginpass -> login_password
loginuser -> login_user
loginhost -> login_host
Add an example playbook that shows how to use the modules.
These modules are based on the mysql_db and mysql_user modules.
Currently, the postgresql_user module can only grant all permissions
on a database, fine-grained access has not been implemented yet.
1. Passing the module to the various functions so that they can use module.fail_json and module.exit_json methods inside.
2. Because of point 1, install and remove methods do not return anything. Instead, they use the module functions itself.
3. Move the import statement (for apt and apt_pkg) inside main function so on import error, we can use module.fail_json to print the error.
This drops the branch option. The version option is overloaded
to mean either a sha1, branch, or tag. This also adds the option
'remote' which defaults to 'origin'.
clone() was simplified by removing the checkout operation. That
happens later when switch_version() is called.
Added the methods get_branches(), is_remote_branch(), and
is_local_branch(). get_branches() returns an array listing all
of the branches for the git repository. is_remote_branch() checks
whether the arguments supplied correspond to a remote branch.
Similarly, is_local_branch() checks for a local branch.
The pull() method now checks to see if it is on the desired branch.
If not, it checks out the requested branch and then does a pull.
This should keep issue #604 still fixed.
switch_version(), formerly switchver(), looks to see if it is
checking out a branch. If a branch, it checks it out with the --track
option. This type of checkout was in pull() before.
Updated pull, clone, and switch_version to return (rc, out, err).
Module consumers using the API don't have to know how this works. base64 stuff is only there
because escaping a docstring inside a docstring was a bit of a challenge :)
get module (with new module-magic-code!)
Usage: ansible -m get -a "url=http://xxxxxxx dest=fileordirctory"
all cleanups as per @mpdehaan's suggestions
add daisychain
added example playbook (get_url.yml) with URLencode example
get_interfaces() updated to read /proc/net/dev. This means it no
longer provides only interfaces that are up.
get_iface_hwaddr() updated to read from /sys/class/net/<iface>/address.
Added get_interface_facts() to pull in mac address and interface mtu.
Can be used later for additional interface-facts.
Added get_ipv6_facts(), which reads from /proc/net/if_inet6.
get_network_facts() renamed to get_ipv4_facts(). It still calls
ifconfig to determine ipv4 facts.
The Facts class and subclasses no longer take a dict argument for
instantiation. populate() now returns self.facts.
Other changes:
- Facts.__init__() takes over most of the work from populate() so that
subclasses can benefit from its knowledge.
- Drop setting unknown facts to 'NA' in __init__() in various
subclasses.
- Check for presence of facts in get_virtual_facts()
- Update ansible_facts() to use facts.update(<classname>().populate())
This changes and organizes facts into a base class Facts and several
sub classes that implement the necessary functionality. The classes
are:
- Facts: base class. Implements basic facts that should be common to a
number of platforms. It is also where SSH keys and SELinux facts are
set.
- Hardware: A subclass of Facts that should be further
subclassed per platform for CPU, memory, and related facts.
- LinuxHardware: subclass of Hardware for Linux platforms
- SunOSHardware: subclass of Hardware for SunOS platforms
- FreeBSDHardware: subclass of Hardware for FreeBSD
- Network: A subclass of Facts that that should be further
subclassed per platform for IP, both IPv4 and IPv6, information.
- LinuxNetwork: Currently only implementation for determining network
facts.
- Virtual: A subclass of Facts that that should be further
subclassed per platform to determine virtual environment facts.
- LinuxVirtual: Currently only implementation for determining virtual
facts.
If facts are needed for additional platforms, one of the above classes
(eg Network) can be further subclassed and implement the necessary
functionality.
In addition, it fixes get_network_facts() to work on Fedora17. That
broke due to changes to ifconfig output.
should be a huge reduction of total ansible source, at a slight cost of difficulty in original module development.
We need to apply this now to all modules, but may need to have some exemptions to things like command, which should
subclass this module.
The service module was printing stuff to stderr, returning two
JSON dicts, not using consistent 'failed' values, had dead code
and unused variables. Added detection for the case when service
status returns 'xxx is dead and pid file exists' and made the
code a bit easier to read.
(Also a fix for the user module error handling when the user
is not present at the time of the return. This can only really be caused by multiple ansible executions).
Takes a lot of the fixes to the user module and applies them to the
group module: provide stdout/stderr in result if available and call
fail_json() if the attempted action fails.
The user module now returns the output, both stdout and stderr, from
useradd, usermod, and userdel. This should help debug cases why one of
those commands fail. In addition, the user module will now call
fail_json() when the attempted command failed so as to properly
communicate a failure in a playbook.
This flag will show playbook output from non-failing commands. -v is also added to /usr/bin/ansible, but not yet used.
I also gutted some internals code dealing with 'invocations' which allowed the callback to know what module invoked
it. This is not something 0.5 does or needed, so callbacks have been simplified.
- Added Upstart support
- Added an initial unknown state
- Prevented state changes when the current state is not recognized
- Changed the keyword recognition to a safer method
Tested with OS X local connection and Linux remote. The paths to the
md5sum and md5 commands are hardcoded to the most common location. This
will definitely fail if the commands are elsewhere, or if the md5
command doesn't support the -q 'quiet' option.
This adds a module that concatenates (ie. assembles) a file from
fragments in a directory in alphabetical order. It chains the file
module afterward to fix up ownership and permission. This also adds
tests for the assemble module with fragments in assemble.d.
This switches to using selinux library calls instead of parsing the
output of sestatus. This fixes issue #428 where the output was slightly
different than expected on F17. Tested against debian (non-selinux),
centos5, centos6, and fedora17.
I think when we stopped using stderr for debugging modules because
paramiko didn't like it, many modules used the idiom of defining
a debug function that used standard error. The def's and calls were
removed.
This looks like a stray debug() that didn't get removed and didn't
show up unless you alter a user's groups. If it's hit, 'user' fails
with a global undefined function error.
The ohai and facter modules use /usr/bin/logger to log the fact that
they have been invoked. I added 'import os' to the ping module
so that it could have the same syslog statements as the other modules.
I separated the condensed:
shlex.split(open(argfile, 'r').read())
into two separate statements similar to the other modules.
This adds some logic when usings groups possibly in combination with append
if just specifying groups and the current groups do not match the list
set groups
if specifying groups with append and any group thats not in the current groups
set groups with -a
Checks if update-rc.d (Ubuntu) or chkconfig (RHEL) should be used.
Adds basic bin path search for those binaries
Adds 'enable' and 'disable' options for 'enable' command since it's the
arguments that update-rc.d uses (this might be somewhat confusing to
have a command line with 'enable=enable', but probably mkes sense for
Ubuntu users).
Allows use of mixed case for 'list' and 'state' commands.
This removes the 'context' option and replaces it with checks for
'_default' value for seuser, serole, setype, or (maybe) selevel.
If '_default' is provided *and* there is a default context for the given
file, this will set the file context to the available default.
Creates system accounts/groups; corresponds to the '-r' option for {user,group}add.
The option is only honored when users/groups are added, not when modified.
When running the service module via sudo, `$PATH` didn't contain `/sbin`,
so the service binary couldn't be found. This just runs `/sbin/service`
directly. Output is spewed to stderr on error.
Added `list=status` to include the output of `service <cmd> status`.
This adds selinux_mls_enabled() and selinux_enabled() to detect a)
whether selinux is MLS aware (ie supports selevel) and b) whether
selinux is enabled. If selinux is not enabled, all selinux operations
are punted on -- same as if python's selinux module were not available.
In set_context_if_different(), I now iterate over the current context
instead of the context argument. Even if the system supports MLS, it
may not return the selevel from selinux.lgetfilecon(). Lastly, this
drops selinux_has_selevel() in lieu of the current approach.
Older versions of selinux, such as that deployed on rhel5, only return a
context of user:role:type instead of user:role:type:level. This detects
whether the tuple has three elements (old-style) or four. If the
old-style, it keeps the secontext list at three elements.
The value is passed to apt-get's "-t" option. Useful for installing backports, e.g.:
ansible webservers -m apt -a "pkg=nginx state=latest default-release=squeeze-backports"
This adjusts behavior of file module such that removal of se* option
does not revert the file's selinux context to the default. In order to
go back to the default context according to the policy, you can use the
context=default option.
This collects various facts from the host so that it isn't necessary to
have facter or ohai installed. It gets various platform/distribution
facts, information about the type of hardware, whether a virtual
environment and what type, assorted interface facts, and ssh host public
keys. Most facts are flat. The two exceptions are 'processor' and all
interface facts. Interface facts are presented as:
ansible_lo : {
"macaddress": "00:00:00:00:00:00",
"ipv4": { "address": "127.0.0.1", "netmask": "255.0.0.0" },
"ipv6": [
{ "address": "::1", "prefix": "128", "scope": "host" }
]
}
This adds the options: seuser, serole, setype, and serange to the file
module. If the python selinux module doesn't exist, this will set
HAVE_SELINUX to False and punt in the related modules.
This takes the options the user provides and applies those to the
default selinux context as provided from matchpathcon(). If there is no
default context, this uses the value from the current context. This
implies that if you set the setype and later remove it, the file module
will rever the setype to the default if available.
is still kicking off. Should not happen except in modules that are somewhat slow to load and probably
can be fixed better than the included sleep, i.e. some IPC communication that the process has
launched and is ok to exit. This works pretty well for now though.
This adds two options to the user module: groups and append. groups is
a comma-delimited list of supplementary groups a user should belong to.
If a user is currently a member of a group not listed in groups, the
user will be removed from it. To change this behavior, use append=yes.
This will append the user to the list of supplementary groups and *not*
remove the user from unlisted groups.
This relies on groupadd, groupmod, groupdel, and gpasswd utilities on
the system. You can optionally modify the gid for the group. You can
also add/remove a user to/from a group with the option member. Member
state is defined with the option memberstate.
This changes the gid option to group. One may provide a primary group
as either a gid or a name. The module will then check to verify that
the group already exists. If the group does not already exist, the
module will fail.
This relies on useradd, usermod, and userdel utilities on the system.
The argument name is required; if state is not provided, present is
assumed. Other options supported for creating or modifying an existing
account: uid, gid, comment, home, shell, and password. If managing the
password, it must already be encrypted. When creating an account, you
can also provide the argument createhome to control whether the home
directory is created. Arguments supported for deleting an account are:
force (remove account even if user is logged in) and remove (remove home
directory).

there are probably some quirks here we'll want to refine further later, for instance, we should
be able to do nicer things with "can't contact host tracebacks".
module vs command module for restarting. May be some bugs and requires the service to implement 'status' -- and probably some better error handling (i.e. return JSON with "failed" element if failed).
Improvements welcome.
