Description
While trying to use the Stdlib function to_yaml() I believe I have discovered a bug in how Puppet handles data returned from Ruby 3.x API functions versions when passed into 4.x Ruby functions.
It is easiest to explain with a reproducer. Give this code, where func3() and func4() are just Ruby API 3.x and 4.x functions respectively that each just return the value they were passed:
$orig_hash = {
|
'mykey' => undef,
|
'otherkey' => 'test',
|
}
|
|
|
$func4_hash = func4($orig_hash)
|
notice("func4_hash: ${func4_hash}")
|
notice("func4_hash_json: ${to_json($func4_hash)}")
|
notice("func4_hash_yaml: ${to_yaml($func4_hash)}")
|
|
|
$func3_hash = func3($orig_hash)
|
notice("func3_hash: ${func3_hash}")
|
notice("func3_hash_json: ${to_json($func3_hash)}")
|
notice("func3_hash_yaml: ${to_yaml($func3_hash)}")
|
I get this output:
$ puppet apply --modulepath=. test/test.pp
|
Notice: Scope(Class[main]): func4_hash: {mykey => , otherkey => test}
|
Notice: Scope(Class[main]): func4_hash_json: {"mykey":null,"otherkey":"test"}
|
Notice: Scope(Class[main]): func4_hash_yaml: ---
|
mykey:
|
otherkey: test
|
|
|
Notice: Scope(Class[main]): func3_hash: {mykey => , otherkey => test}
|
Notice: Scope(Class[main]): func3_hash_json: {"mykey":"undef","otherkey":"test"}
|
Notice: Scope(Class[main]): func3_hash_yaml: ---
|
mykey: :undef
|
otherkey: test
|
|
|
Notice: Compiled catalog for msp-pumtl31.msp.secure-24.net in environment production in 0.02 seconds
|
Notice: Applied catalog in 0.01 seconds
|
Note how the original data structure is correctly passed to the 4.x function with a nil value the first time, but after passing through a 3.x function the 4.x function now receives :undef and not nil.
The expected behavior is that a 4.x Ruby function would always receive nil when passed a Puppet undef value, regardless of whether it has passed through a 3.x style function or not.
Thank you.
