Bug description: SentText infinite loop
Description:
------------
When a message is > 1024 bytes in size and therefore broken down into 1024
chunks, there is a 'goto send_chunk;' being called an infinite number of
times because the conditional statement 'if ((parts * 1024) <
data_cln_len)' is always true if it is ever true. This basically causes
the function to just keep on sending data to the smtp server.
Problem wasnt there in RC1, just RC2 and RC3.
Reproduce code:
---------------
int parts = (int) floor(data_cln_len / 1024);
p = data_cln;
for (i = 0; i < parts; i++) {
strlcpy(Buffer, p, 1024);
Buffer[1024] = '\0';
p += 1024;
send_chunk:
/* send chunk */
if ((res = Post(Buffer)) != SUCCESS) {
efree(data_cln);
return (res);
}
}
if ((parts * 1024) < data_cln_len) {
i = data_cln_len - (parts * 1024);
strlcpy(Buffer, p, i);
Buffer[i] = '\0';
goto send_chunk;
}
Expected result:
----------------
Data is sent in 1024 byte chunks. The remainder is then sent. Send is then
terminated with '\r\n.\r\n'
Actual result:
--------------
Data is sent in 1024 byte chunks. The remainder is then sent...again and
again and again and again. etc etc.
Send is never terminated.
