Add the ability to completely delete a floating IP from the pool
when disassociating it from a server. When state is absent and
purge is true, the IP will be completely deleted. The default
keeps the current behavior, which is to only disassociate the IP
from the server.
The exception message, when shade fails, will contain much more
specific information about the failure if the exception is treated
as a string. The 'message' attribute alone is usually not helpful.
Support specifying an absolute path (typically /etc/crontab) rather than
a path relative to /etc/cron.d, to allow modifying the main system crontab.
Particularly useful for target systems that have /etc/crontab but no
/etc/cron.d.
Since use_unsafe_shell is suspicious from a security point
of view (or it wouldn't be unsafe), the less we have, the less
code we have to toroughly inspect for a security audit.
In this case, the '&&' can be replaced by doing 2 calls to run_command.
Starting in Django 1.7, the createcachetable command looks for cache
table names in the CACHES settings dictionary, so cache_table is no
longer required, but is still allowed.
Otherwise CDN (Akamai) downloads file without the headers. The sequence
is following:
1. Ansible uploads file to CF.
2. Akamai downloads the file and caches it in CDN.
3. Ansible sets headers.
As a result Akamai serves file without headers.
This is backwards incompatible change, because headers keys are not
prefixed with `x-object-meta-`. Which allows user to set headers like
`Access-Control-Allow-Origin`.
The command `hg up -C` by default moves to the latest revision on the
current branch. The `discard` function was trying to update to a
different branch, in case it was provided, by passing a `-r REVISION`
argument. Not only is this not the intended effect of the `discard`
function, but this also could update to a different branch that hasn't
been pulled yet, which is how we were experiencing trouble.
Instead, we unconditionally do `hg up -C -r .` to "update" to the
current revision (i.e. to "."), while `-C/--clean`ing the current
directory. This is similar to `hg revert --all`, except that it also
undoes the merge state of the working directory, in case there was
any.
