I also couldn't get file selection rules to work using the "/path/to/*/*.pl"
files promises. So what I ended up doing is writing a module using find to
return all of the matched files I need to edit. To get around the 4K line
length limit (yet another arbitrary limit), my module counts the accumulated
characters in the output, and creates a series of numbered slists (l1, l2, l3,
etc), each within the allowable line length. Then it also returns a meta-list
which contains the names of all the sub-lists. I have a parametrized bundle
which takes the name of a sublist, and it's called by iterating over the
metal-list. I couldn't figure out how to access the list by name (the
@($(var)) syntax wasn't real obvious to me at the time, and I'm still not
positive that it'd work), so I ended up creating a new list by joining and then
re-splitting, as in:
vars:
"separator" string => "<=>";
"executable_list" slist => splitstring(
join( "$(separator)", "$(listname)" ),
"$(separator)",
"inf"
);
Which is just the cherry on top of this whole workaround for something that's
limited because "it's too dangerous" - while recursive directory emptying is
clearly not too dangerous at all. ;) This part of my policy takes about 20
minutes to evaluate over something like 32K files, for the record. It should
probably just all be done in a much faster external script with different
return codes, but I've been stubborn about doing as much native to CFEngine as
possible...
