Introspection on errorStrategy alters its expected effect.

[muniheart]

[ nextflow version 24.04.2.5914 ]

Consider the following workflow,

process foo {

    errorStrategy { task.exitStatus == 2 && task.attempt<3 ? 'retry' : 'terminate' }

    script:
    """
    exit 2
    """
}

process bar {

    errorStrategy { task.exitStatus == 2 && task.attempt<3 ? 'retry' : 'terminate' }

    script:
    log.info "$task.process: errorStrategy: $task.errorStrategy"
    """
    exit 2
    """
}

workflow {
    foo()
    bar()
}

Expected behavior and actual behavior

Each of the processes foo and bar should be run twice, but that is not what I observe. It seems that introspection of task.errorStrategy in process bar is somehow altering the expected behavoir, which is that exhibited by process foo.

Steps to reproduce the problem

nextflow run .
