Re: Question about adding subscriptions without refresh.

Mark,

Your fix is correct. The current implementation is clearly wrong. I am not sure
when this was introduced, but I suspect it was a recent change. It might be
worth looking into.

In developing a transport bridge for openMAMA, I came across what I believe
is an issue with mama/c_cpp/src/c/transport.c. The
mamaTransport_addSubscription() will return MAMA_STATUS_NOMEM if the
self->mRefreshTransport is not set. This blocked us from successfully
establishing a subscription in the case where a refresh was not desired.

 

I have a patch that I could submit that would change the method to the
following. But before doing so, I’d like to ask if there is anything I
missed? Below is how we updated the code to work.



mama_status
mamaTransport_addSubscription (mamaTransport    transport,
                               mamaSubscription subscription,
                               void**           result)
{
    SubscriptionInfo*   handle = NULL;
 
    if (self->mRefreshTransport) {
        handle = refreshTransport_allocateSubscInfo (self->mRefreshTransport);
 
        if (handle == NULL) return MAMA_STATUS_NOMEM;
 
        handle->mSubscription = subscription;
    }

    *result = handle;

    if (self->mRefreshTransport)
        refreshTransport_addSubscription (self->mRefreshTransport, handle);

    return MAMA_STATUS_OK;
}

 

Thanks

Mark
