[HTCondor-users] "if defined" fails for VARS from DAG

[Marco van Zwetselaar <zwets@xxxxxxxxxx>]

    It seems as though VARS defined in a DAG get carried over into the
    node's job file, but don't make 'if defined' true. Here is a test
    case:
    
    ÂÂÂ test.job:
    ÂÂÂ executable = /usr/bin/echo
    ÂÂÂ if defined A
    ÂÂÂ ÂÂ arguments = "defined A=$(A)"
    ÂÂÂ else
    ÂÂÂ ÂÂ arguments = "undefined A=$(A)"
    ÂÂÂ endif
    ÂÂÂ output = test.out
    
    ÂÂÂ test.dag:
    ÂÂÂ VARS test A="42"
    ÂÂÂ JOB test test.job
    
    Now, 'condor_submit A=99 test.job' correctly results in 'defined
    A=99', whereas 'condor_submit_dag test.dag' results in 'undefined
    A=42'. This is unexpected: A is undefined, yet appears to have value
    42.
    
    Kind regards,
    Marco
