Subject Re: Patch option 1 - with apr_socket_create_protocol()
Date Fri, 18 Oct 2002 13:03:32 GMT

Ok I just stole a few cycles and had a look... some quick comments.

1) In the network_io/win32/sockets.c

    the call from apr_socket_create() to -> apr_socket_create_ex()

   is going to not compile since you put in a variable "protocol" which
   is not defined in the function.. I think you meant to put '0' in here
   like you did in the other 2.

2) The change in apr_os_sock_put to specify TCP is, IMO, the wrong
    thing to do... A quick check of cscope in httpd shows 6 users of
    this call and of those 6, 4 of the uses are for NON-TCP sockets (at
    least I think they are.. called things like the "pipe of death" etc.
    Of the 2 that use TCP .. once SCTP shows up this will cause
    some problems (at least in the mpm files). They are passing the
    listener sockets to the child and setting them. One of them knows
    the protocol (if it cared to get it) the other does not.. and
    I would imagine will need to send it...

    Maybe for now just specifying '0' .. or maybe we need a
    APR_PROT_UNKNOWN -> 0... definition. Sigh.. ugly either
