http://d.puremagic.com/issues/show_bug.cgi?id=4344 Summary: Sockets with multiple threads report missing/failed WSAStartup Product: D Version: D2 Platform: x86_64 OS/Version: Windows Status: NEW Severity: normal Priority: P2 Component: Phobos AssignedTo: nobody puremagic.com ReportedBy: epi atari8.info Created an attachment (id=666) source for server and client to reproduce this issue Hello, I encountered a strange problem dealing with sockets and threads under Windows (I use 64-bit 7 Pro). The server socket successfully accepts a connection and passes obtained socket to newly created thread, which deals with it correctly. However, the server socket then breaks with the exception on any next operation. The SocketException.errorCode is always 10093, which stands for missing or failed WSAStartup. Indeed, when I place WSAStartup after accepting connection, it works well (but most probably needs matching WSACleanup() call). The single-threaded version also presents no problems. I tried with DMD 2.046 and 2.047 with same result. I attach example sources of both server and client showing the issue. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

Sample: ---------------------------------------------------- import core.thread; import std.socket; void main() { auto thread = new Thread({}); thread.start(); thread.join(); auto socket = new TcpSocket; } ---------------------------------------------------- Results: ---------------------------------------------------- std.socket.SocketException: Unable to create socket ---------------------------------------------------- And I found following code in /trunk/phobos/std/socket.d. 193 static ~this() 194 { 195 version(Win32) 196 { 197 WSACleanup(); 198 } 199 } 200 I think that "shared static ~this()" is correct. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

"shared static ~this" seems to do the trick for now, but when building a DLL, unloading it will also kill connections of the whole application. I'd say the calls to WSAStartup and WSACleanup should be explicite. Fortunately, in my case, the DLL is never unloaded... -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

If you wish, open a separate issue for that. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
