Based on ideas from Kim F. Storm <storm@cua.dk>, see http://lists.gnu.org/archive/html/emacs-devel/2006-12/msg00873.html. src/w32proc.c (reader_thread): If the FILE_CONNECT flag is set, call '_sys_wait_connect'. If it returns STATUS_CONNECT_FAILED, exit the thread with code 2. (sys_select): Support 'wfds' in addition to 'rfds'. If a descriptor in 'wfds' has its bit set, but the corresponding fd_info member doesn't have its FILE_CONNECT flag set, ignore the descriptor. Otherwise, acknowledge a successful non-blocking connect by resetting the FILE_CONNECT flag and setting cp->status to STATUS_READ_ACKNOWLEDGED. src/w32.h (STATUS_CONNECT_FAILED): New enumeration value. (struct _child_process): New member 'errcode'. (FILE_CONNECT): New flag. (_sys_wait_connect): Add prototype. src/w32.c (pfn_WSAEnumNetworkEvents): New function pointer. (init_winsock): Load WSAEnumNetworkEvents from winsock DLL. (set_errno): Map WSAEWOULDBLOCK and WSAENOTCONN. (sys_connect): Support non-blocking 'connect' calls by setting the FILE_CONNECT flag in the fd_info member and returning EINPROGRESS. (_sys_read_ahead): Add debug message if this function is called for a descriptor that waits for a non-blocking connect to complete. (_sys_wait_connect): New function. (sys_read): Support STATUS_CONNECT_FAILED. Return the error code recorded by _sys_wait_connect when the non-blocking connect failed. Don't call WSAGetLastError before a call to set_errno had a chance to use its value, since WSAGetLastError clears the last error. nt/inc/ms-w32.h (BROKEN_NON_BLOCKING_CONNECT): Don't define. |
