Issue #12479 has been updated by Nicolas Simonds.
A look over the results of the test script shows it matching on the letters D, E, F, N, and U. I'm no expert, but I'm pretty sure those letters spell "undef". ---------------------------------------- Bug #12479: Regression: Regex matching against non-existant facts results in false-positive https://projects.puppetlabs.com/issues/12479 Author: Nicolas Simonds Status: Unreviewed Priority: Normal Assignee: Category: Target version: Affected Puppet version: Keywords: Branch: Non-existant facts are stringify-ing under the hood as something, which causes them to match regexes, despite returning nil when otherwise asked. A simple bash script to test: ---- #!/bin/bash for LOLWUT in {a..z} do cat <<- EOF > /tmp/test.pp case \$wtf { /$LOLWUT/: { notice("The fact[\$wtf] matches the regex /$LOLWUT/") } default: { notice("The fact[\$wtf] does NOT match the regex /$LOLWUT/") } } notice(\$facility) EOF puppet apply /tmp/test.pp done ---- Expected result: All notices that the non-existant fact doesn't match. Actual result: Various and sundry notices that it matched. BAD PUPPET! NO COOKIE! -- You have received this notification because you have either subscribed to it, or are involved in it.
