Summary|std.socket.TcpSocket.accept |std.socket.TcpSocket.connect
|blocks forever |doesn't actually connect
Just a drive-by. Simplified testcase:
---
import std.socket, std.stdio;
void main()
{
// Replace 12345 with any unused port.
auto address = new InternetAddress("127.0.0.1", 12345);
try
{
auto client = new TcpSocket();
client.connect(address);
writefln("Where's my error?");
}
catch (SocketException)
writefln("Success");
}
---
Testcase succeeds on Windows, but not Linux, using 2.028 and CentOS 5.3. Most
likely, incorrect size of the sockaddr_in struct or something.

Set sin_family properly.
Pruning down some C-style socket code, I determined that sin_family was the
deciding factor on this behavior. Unfortunately, it is unclear to me why this
would've regressed from 2.026 (since sin_family has never been set?)
Graham, you can work around this issue and verify the fix by recompiling phobos
or by writing a subclass for InternetAddress, e.g.:
---
import std.c.linux.socket, core.sys.posix.sys.socket;
import std.socket;
class MyInternetAddress: InternetAddress
{
this(string addr, ushort port)
{
sin.sin_family = AddressFamily.INET;
super(addr, port);
}
this(uint addr, ushort port)
{
sin.sin_family = AddressFamily.INET;
super(addr, port);
}
this(ushort port)
{
sin.sin_family = AddressFamily.INET;
super(port);
}
}
---
If you could verify this fixes your issue, it would be appreciated.
Thanks,

http://d.puremagic.com/issues/show_bug.cgi?id=2835 It did indeed fix the issue. My (improved) test code now works in 2.026 and 2.028 when I use the workaround. --

I can confirm this patch applying cleanly to the latest Phobos. Can we get this
in for the next DMD release? It's no exaggeration to say that working sockets
to some are both their bread and butter.

Phobos1 has the same problem.
I am happy that this fix will be applied to the phobos1 too.
Thanks.
