[tor/maint-0.2.2] Log descriptions of nodes, not just nicknames.

commit b95dd03e5f6505ce2e78fe34a20bf5e5c970e6eb Author: Nick Mathewson <nickm(a)torproject.org> Date: Sun May 15 21:58:46 2011 -0400 Log descriptions of nodes, not just nicknames. This patch introduces a few new functions in router.c to produce a more helpful description of a node than its nickame, and then tweaks nearly all log messages taking a nickname as an argument to call these functions instead. There are a few cases where I left the old log messages alone: in these cases, the nickname was that of an authority (whose nicknames are useful and unique), or the message already included an identity and/or an address. I might have missed a couple more too. This is a fix for bug 3045. --- src/or/circuitbuild.c | 43 +++++++++------- src/or/circuitlist.c | 6 ++- src/or/circuituse.c | 4 +- src/or/command.c | 4 +- src/or/connection_edge.c | 7 ++- src/or/directory.c | 9 ++-- src/or/dirserv.c | 45 +++++++++------- src/or/relay.c | 5 +- src/or/rendclient.c | 19 ++++--- src/or/rendservice.c | 31 +++++++----- src/or/rephist.c | 6 ++- src/or/router.c | 127 ++++++++++++++++++++++++++++++++++++++++++++++ src/or/router.h | 15 ++++++ src/or/routerlist.c | 36 +++++++------ src/or/routerparse.c | 5 +- 15 files changed, 269 insertions(+), 93 deletions(-) diff --git a/src/or/circuitbuild.c b/src/or/circuitbuild.c index 860cd27..469e180 100644 --- a/src/or/circuitbuild.c +++ b/src/or/circuitbuild.c @@ -1753,10 +1753,9 @@ circuit_handle_first_hop(origin_circuit_t *circ) if (!n_conn) { /* not currently connected in a useful way. */ - const char *name = strlen(firsthop->extend_info->nickname) ? - firsthop->extend_info->nickname : fmt_addr(&firsthop->extend_info->addr); log_info(LD_CIRC, "Next router is %s: %s ", - safe_str_client(name), msg?msg:"???"); + safe_str_client(extend_info_describe(firsthop->extend_info)), + msg?msg:"???"); circ->_base.n_hop = extend_info_dup(firsthop->extend_info); if (should_launch) { @@ -2039,7 +2038,7 @@ circuit_send_next_onion_skin(origin_circuit_t *circ) circuit_set_state(TO_CIRCUIT(circ), CIRCUIT_STATE_BUILDING); log_info(LD_CIRC,"First hop: finished sending %s cell to '%s'", fast ?

commit cfeafe5e77c9dd5587b1ec553eb1065f0bf841fd Author: Nick Mathewson <nickm(a)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(-) diff --git a/changes/bug3270 b/changes/bug3270 new file mode 100644 index 0000000..b37bb98 --- /dev/null +++ b/changes/bug3270 @@ -0,0 +1,4 @@ + o Minor bugfixes + - Use a wide type to hold sockets when built for 64-bit Windows builds. + Fixes bug 3270. + diff --git a/src/common/compat.c b/src/common/compat.c index fc066da..9377959 100644 --- a/src/common/compat.c +++ b/src/common/compat.c @@ -841,7 +841,7 @@ socket_accounting_unlock(void) * Windows, where close()ing a socket doesn't work.

[tor/maint-0.2.2] Use a 64-bit type to hold sockets on win64.
by nickm＠torproject.org 30 May '11

30 May '11

commit cfeafe5e77c9dd5587b1ec553eb1065f0bf841fd Author: Nick Mathewson <nickm(a)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(-) diff --git a/changes/bug3270 b/changes/bug3270 new file mode 100644 index 0000000..b37bb98 --- /dev/null +++ b/changes/bug3270 @@ -0,0 +1,4 @@ + o Minor bugfixes + - Use a wide type to hold sockets when built for 64-bit Windows builds. + Fixes bug 3270. + diff --git a/src/common/compat.c b/src/common/compat.c index fc066da..9377959 100644 --- a/src/common/compat.c +++ b/src/common/compat.c @@ -841,7 +841,7 @@ socket_accounting_unlock(void) * Windows, where close()ing a socket doesn't work.
