Jakob Odersky created TOREE-365: ----------------------------------- Summary: Certain interpreter evaluations do not return result strings Key: TOREE-365 URL: https://issues.apache.org/jira/browse/TOREE-365 Project: TOREE Issue Type: Bug Reporter: Jakob Odersky
The scala interpreter currently only returns results for expressions. Import statements and declarations will not show up as results in a notebook (although they are evaluated internally). This behaviour is related to the [ScalaInterpreter#truncateResult|(https://github.com/apache/incubator-toree/blob/master/scala-interpreter/src/main/scala/org/apache/toree/kernel/interpreter/scala/ScalaInterpreter.scala#L165-L187] function. This function runs the result string of a REPL line through a regex, in order to remove the "resX:" part. The function returns the empty string in case the line does not start with "resX:", therefore returning an empty string for import statements and other declarations. This can have several subtle side effects, such as TOREE-340, or a toree client never completing the "onResult" callback. A quick fix to this issue is to return the result string as-is if it does not start with "resX". -- This message was sent by Atlassian JIRA (v6.3.4#6332)
