2012-02-04Fix port leaking after controlling_process(Port, self())Ricardo
Add case to handle the situation when someone call {gen_tcp,gen_udp}:controlling_process(Port, self()). Also improve spec and doc from gen_udp and gen_sctp for controlling_process/2. To reproduce the issue, open an UDP port: 4> {ok,Port} = gen_udp:open(9000, [binary]). {ok,#Port<0.587>} 5> gen_udp:controlling_process(Port, self()). ok Simulate error: 6> 1=2. ** exception error: no match of right hand side value 2 Here is the leak: 7> inet:i(). Port Module Recv Sent Owner Local Address Foreign Address State Type 581 inet_udp 0 0 <0.31.0> *:cslistener *:* BOUND DGRAM ok
2011-08-27Fix type of Packet arg of gen_tcp:send/2 and gen_udp:send/4Filipe David Manana
The type is marked as a binary() or a string() but in practice it can be an iodata(). The test suite was updated to confirm the gen_tcp/2 and gen_udp:send/4 functions accept iodata() (iolists) packets.

2010-09-06Let an 8-tuple given as ip_address() for gen_tcp/gen_udp/gen_sctp imply 'inet6'Per Hedeland
Currently an 8-tuple representing an IPv6 address is not accepted by gen_tcp:listen/2, gen_tcp:connect/3,4, gen_udp:open/2, or gen_sctp:open/1,2, unless the 'inet6' option is also given. This means that an application that has obtained the address, e.g. from configuration that allows for either IPv4 or IPv6, must always check the type of the address before passing it to these functions. Letting the functions infer 'inet6' from the 8-tuple, in case other options do not override this choice, improves usability.
