commit cfeafe5e77c9dd5587b1ec553eb1065f0bf841fd Author: Nick Mathewson nickm@torproject.org Date: Mon May 23 00:17:48 2011 -0400

Use a 64-bit type to hold sockets on win64.

On win64, sockets are of type UINT_PTR; on win32 they're u_int; elsewhere they're int. The correct windows way to check a socket for being set is to compare it with INVALID_SOCKET; elsewhere you see if it is negative.

On Libevent 2, all callbacks take sockets as evutil_socket_t; we've been passing them int.

This patch should fix compilation and correctness when built for 64-bit windows. Fixes bug 3270. --- changes/bug3270 | 4 +++ src/common/compat.c | 32 +++++++++++---------- src/common/compat.h | 21 ++++++++++---- src/common/compat_libevent.h | 4 +++ src/common/util.c | 8 +++--- src/common/util.h | 4 +- src/or/buffers.c | 8 +++--- src/or/buffers.h | 4 +- src/or/connection.c | 50 +++++++++++++++++---------------- src/or/control.c | 2 +- src/or/cpuworker.c | 10 +++--- src/or/dnsserv.c | 2 +- src/or/eventdns.c | 2 +- src/or/eventdns.h | 2 +- src/or/main.c | 62 +++++++++++++++++++++-------------------- src/or/or.h | 2 +- 16 files changed, 120 insertions(+), 97 deletions(-)
