             Summary: Filters.filterToFilterSpec fails if ANY or ALL include legal undefined fields
                 Key: WFCORE-3256
                 URL: https://issues.jboss.org/browse/WFCORE-3256
             Project: WildFly Core
          Issue Type: Bug
          Components: Logging
            Reporter: Brian Stansberry
            Assignee: James Perkins
            Priority: Minor


Say you have a filter value like this:

{code}
{
    "any" => {
        "match" => ".*",
        "change-level" => undefined,
        "level" => undefined,
        "level-range" => undefined,
        "not" => undefined
    },
    "all" => undefined,
    "change-level" => undefined,
    "level" => undefined,
    "level-range" => undefined,
    "not" => undefined
}
{code}

Writing that will fail with "WFLYLOG0025: Filter ("change-level" => undefined) is invalid".

This is because filterToFilterSpec will process the "any" node by iterating over its fields and recursing, and as soon as it gets to one of the 'undefined' ones it will fail. But the overall structure should be fine.

I hit this when testing a WFCORE-3255 fix, one that had the effect of adding "change-level" => undefined, etc to the params used by LoggingOperationsSubsystemTestCase.testLegacyFilters.

I can probably work around this easily enough and IIRC this 'filter' stuff is real old, so this is no big deal.
