Checkmk Werk 13478: Mitigate wrong converion of disabled service rules on update

ID: 13478 Title: Mitigate wrong converion of disabled service rules on update Component: Setup Level: 1 Class: Bug fix Version: 2.1.0i1 During <tt>cmk-update-config</tt> some disabled services rules are being broken by introducing an undesired escaping. This werk reduces the number of cases in which this happens. Users "Disabled Services" rules were affected if they fullfilled <b>all</b> of the following criteria: <ul> <li>They have exactly one host condition (explicit or pattern)</li> <li>They have no tag based conditions</li> <li>All their patterns for the service name end in "<tt>$</tt>"</li> </ul> After this werk, only rules will be affected if they additionally <ul> <li> have exactly one <b>explicit</b> host condition (not a regular expression)</li> <li> contain <b>both</b> quoted and unquoted special characters</li> in their service name pattern </ul> For instance: "<tt>Foo[12]$</tt>" and "<tt>Foo\[12\]$</tt>" will remain unchanged, whereas "<tt>Foo\[1\][2]$</tt>" will be changed to "<tt>Foo\[1\]\[2\]$</tt>". If this still affects you, you can avoid meeting the above criteria. For instance try to replace "<tt>my_hostname</tt>" by "<tt>~^my_hostname$</tt>" or to craft a service name pattern that does not require the trailing "<tt>$</tt>".
