When testparm processes the output of "testparm -v" (which includes
default values) it appears to do global checks (or some other sort of
initialisation logic) for all specified values. This includes a DNS
lookup for the node's hostname, as a side-effect of a libldap
ldap_set_option() call when processing "ldap debug level". If DNS
servers are down then this can induce timeouts, possibly resulting in
monitor timeouts.
Avoid this by using sed to extract configuration values from the
testparm cache file.
This is already shown to work when retrieving share paths, where
testparm is basically used as cat. Update the sed pattern to avoid
matching empty values on the right-hand side of the equals ('=') -
this avoids the default empty path value (and "smb ports" never has an
empty value).
Corresponding test changes:
* 50.samba.monitor.111.sh no longer expects a failure from being
unable to set smb ports, since testparm is no longer used in that
code path.
* smb ports needs to be set in fake smb.conf so it is in the default
output and can be extracted using sed.
* Although testparm --parameter-name is no longer used in
50.samba.script, update the stub implementation (in case it is ever
used again) to extract from fake smb.conf, since "smb ports" is now
set there. The change from $parameter to $param allows a long line
to stay below 80 columns.
