Hello, I discussed this issue in the help ML before but it really appears
like it is a bug.
Basically, cf-engine chokes on ${const.dollar}( ... ) in command strings
passed to returnszero function. However $() in a shell (Bash) can be very
useful as it triggers a subshell. There is a bug in the parser somewhere as
this example demonstrates:
body common control
{
bundlesequence => {"configurePhase"};
}
bundle agent configurePhase
{
classes:
"MyClass" expression => returnszero("/bin/echo
${const.dollar}(cat /etc/hosts)", "useshell");
"MyClass2" expression => returnszero("/bin/echo `cat
/etc/hosts`", "useshell");
reports:
MyClass::
"Hi World";
MyClass2::
"Hello World";
}
MyClass2 will correctly be defined, but not MyClass as cf-engine will refuse
to run the first command - the parser gets confused and attempts to solve
'cat /etc/hosts' as a variable it seems. I checked this on today's SVN and
the problem is still present. Please correct it :)
Cheers
Jean-Noel
