* If a db user belonged to a role which had a privilege, the user would
not have the privilege added as the role gave the appearance that the
user already had it. Fixed to always check the privileges specific to
the user.
* Make fewer db queries to determine if privileges need to be changed
and change them (was four for each privilege. Now two for each object
that has a set of privileges changed).
The default value set by the module was a value of None for the
config_file parameter, which propogates into the connect method
call overriding the stated default in the method.
Instead, the default should be set with-in the parameter
specification so the file check is not requested to check None.
Remove `USAGE` from the `VALID_PRIVS` dict for both database and
table because it is not a valid privilege for either (and
breaks the implementation of `has_table_privilege` and
`has_database_privilege`
See http://www.postgresql.org/docs/9.0/static/sql-grant.html
Use `has_table_privileges` and `has_database_privileges`
to test whether a user already has a privilege before
granting it, or whether a user doesn't have a privilege
before revoking it.
For read-only databases, users should not change when no changes
are required.
Don't issue ALTER ROLE when role attribute flags, users password
or expiry time is not changing.
In certain cases (hashed passwords in the DB, but the password
argument is not hashed) passlib.hash is required to avoid
running ALTER ROLE.
Some places ([AWS RDS](https://forums.aws.amazon.com/thread.jspa?threadID=151248)) don't have, or don't allow, access to the `pg_authid` table. The only reason that is necessary is to check for a password change.
This flag is a workaround so passwords can only be set at creation time. It isn't as elegant as changing the password down the line, but it fixes the longstanding issue #297 that prevented this from being useful on AWS RDS.
Ports are integer values but the old code was assuming they were
strings. When login_port is put into playbook complex_args as an
integer the code would fail. This update should make the argument
validating make sure we have an integer and then we can send that value
directly to the relevant APIs.
Fixes#818
