Sorry to bother again. But this time it's about splitstring and nullbytes.
If I want to get a slist variable with a list of filenames I can use execresult
to call an external command to get a string variable in return and call the
splitstring later on get the actual slist.
Since filenames can contain anything except null-bytes the only save way is
using null-bytes as a delimiter (-print0).
vars:
"files_string" string => execresult("/usr/bin/find /some/path -name
"some_pattern" -print0", "noshell");
If I want to split the string I would do be doing this way:
vars:
"files_list" slist => splitstring("$(files_string)", "\0", "100");
But cfengine doesn't handle "\0" or "\x0" correctly although these are valid
pcre inputs for a null-byte.
If I use "$(const.n)" or "$(const.endl)" the string seems to be chopped after
the first occurrence of a null-byte. The string "first\0second\0third" will be
splitted to "first". That's completely wrong. It should stay unchanged because
there aren't any newlines.
Any ideas how to do the splitting?
