bug in the proxy module ...

[Brasseur Valery]

Hi,

I am using cyrus 2.3.11 in a murder setup... from time to time have got an hang from the pop3 proxyd ...

I nail it donw to the following portion of code :
in imap/proxy.c near line 266 :
<quote>
       if (pout) {
                const char *err;
                char buf[4096];
                int c;

                do {
                    c = prot_read(pin, buf, sizeof(buf));

                    if (c == 0 || c < 0) break;
                    prot_write(pout, buf, c);
                } while (c == sizeof(buf));

                if ((err = prot_error(pin)) != NULL) { </quote>

from time to time, the prot_read return exactly 4096 bytes, but it's the end of the message...
so backend seat and wait for next command, and proxy seat and wait for the next buffer ...
forever !

for me it's seems that the condition " c == sizeof(buf)" is not enough in that case.



have someone else already encoutered this ?


thanks
valery
