FAQ
I sent this once before and didn't hear anything. I just got my third
copy of this. Looking at the mailman-developers archive, it appears that
others are getting it to.

Can we get some kind of word on what the problem is?

thx

    sorry i haven't had time to be more responsive. i've got a lot of other
    work on my hands at the moment, so i'll throw in my best educated
    guess instead of a thorough analysis, and hope it helps.

    First off, i believe that this problem is either system dependent or
    showing itself through list configs that i don't have. i'm not seeing
    this under linux or solaris2.5.1, and both installations have taken a
    bit of a beating.

    secondly, this problem probably results from calling
    os.popen(<prg>, "w") where <prg> does this right off the bat:

    if not os.fork():
    # do the work
    os._exit(0)


    the way i understand os._exit(0) is that it should only be used for
    child processes, not parent processes, when a fork() is done. Perhaps
    there are some underlying things in the system or list configs which
    cause the parent program to exit before the child is done reading
    stdin.

    at any rate, if those who are experiencing this problem could try
    replacing the os._exit(0) in the function "main()" in scripts/deliver
    with "sys.exit(0)" or some such, this *might* fix the problem.

    I *think* that should be changed anyway, but could be mistaken.

    that's my best educated guess.

    if it don't help, i hope to be able to address more of this later this
    week, but can't promise anything yet.

    good luck,

    scott
