2013-02-11Fix type of error Reason on gen_tcp:send/2Sean Cribbs
When the TCP socket is in passive mode, it is possible that a close message has not been delivered to the controlling process before calling send/2. This results in the returning {error, closed} to the caller, in the same way that recv/2,3 does. This commit adjusts the type of the error "Reason" to include the atom 'closed'.

2012-01-04Fix returned error from gen_tcp:accept/1,2 when running out of portsPer Hedeland
The {error, enfile} return value is badly misleading and confusing for this case, since the Posix ENFILE errno value has a well-defined meaning that has nothing to do with Erlang ports. The fix changes the return value to {error, system_limit}, which is consistent with e.g. various file(3) functions. inet:format_error/1 has also been updated to support system_limit in the same manner as file:format_error/1.
2011-12-02Move sendfile api to file moduleLukas Larsson
Since sendfile could in theory be used to send to any type of file descriptor in *nix, it is a better fit to have it in file.
2011-12-01Preliminary work on header/trailerLukas Larsson
Have to figure out how to represent progress in header writing when using non-blocking, not sure how to do this.
2011-12-01sendfile caller now has to be the controlling_processLukas Larsson
This is needed because otherwise there could be scenarios when the efile driver blocks a fd and then crashes without the inet driver ever finding out. Now when the process crashes the port will close and we can cleanup in the inet driver.
2011-12-01Remove support for file_server, sendfile has to be rawLukas Larsson
Because the sending process has to be the controlling process of the tcp socket used to send data it is not possible to use the file_server
2011-12-01Implement ignorefd for TCPLukas Larsson
Ignore fd is a feature used by sendfile to temporarily remove all driver_select calls on that fd so that another driver can select on it. It also delays all actions which sends or receives data in that fd until in the fd is no longer ignored. Only the controlling_process should use the feature as it is otherwise possible that the ignore will never be cleaned up and hence create a memory leak in the driver. An ignored driver will not detect that an fd has been closed until it is unignored.
2011-12-01Implement blocking calls for sendfileLukas Larsson
Move sendfile data to invoke data instead of file_descr. Remove usage of ready_output when doing a send. If told to send 0 bytes, file_sendfile now sends the entire file for linux.
2011-12-01Implement sendfile using blocking io in asynch threadsLukas Larsson
Move the command handling to outputv in preparation for header and trailer inclusion in the sendfile api. Use the standard efile communication functions for sendfile.
2011-12-01Create erlang fallback for sendfileLukas Larsson
Created erlang fallback for sendfile in gen_tcp and moved sendfile from file to gen_tcp. Also created testcases for testing all different options to sendfile. For info about how sendfile should work see the BSD man pages as they contain a more complete API than other *nixes.
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.
