From 1413510ed2d8175dcce7c2c14c02e720c8406429 Mon Sep 17 00:00:00 2001 From: akr Date: Thu, 26 Apr 2012 03:34:12 +0000 Subject: [PATCH] * ext/socket/raddrinfo.c (init_unix_addrinfo): support the longest path in sockaddr_un. (inspect_sockaddr): ditto. (addrinfo_mdump): ditto. (addrinfo_mload): ditto. (rsock_unixpath_str): new function. (rsock_unixpath): removed. (rsock_unixaddr): use rsock_unixpath_str. * ext/socket/socket.c (sock_s_pack_sockaddr_un): support the longest path in sockaddr_un. (sock_s_unpack_sockaddr_un): ditto. (sock_s_gethostbyaddr): unused variable removed. * ext/socket/unixsocket.c (rsock_init_unixsock): support the longest path in sockaddr_un. * ext/socket/rubysocket.h (rsock_unixpath_str): declared. (rsock_unixpath): removed. * test/socket/test_unix.rb: comment out test_nul because abstract unix sockets may contain NULs. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@35474 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- ChangeLog | 25 +++++++++++++++++++ ext/socket/raddrinfo.c | 54 +++++++++++++++++++--------------------- ext/socket/rubysocket.h | 2 +- ext/socket/socket.c | 23 ++++++----------- ext/socket/unixsocket.c | 6 ++--- test/socket/test_unix.rb | 7 +++--- 6 files changed, 65 insertions(+), 52 deletions(-) diff --git a/ChangeLog b/ChangeLog index 6e7c4be136..59639f8461 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,28 @@ +Thu Apr 26 12:28:06 2012 Tanaka Akira + + * ext/socket/raddrinfo.c (init_unix_addrinfo): support the longest + path in sockaddr_un. + (inspect_sockaddr): ditto. + (addrinfo_mdump): ditto. + (addrinfo_mload): ditto. + (rsock_unixpath_str): new function. + (rsock_unixpath): removed. + (rsock_unixaddr): use rsock_unixpath_str. + + * ext/socket/socket.c (sock_s_pack_sockaddr_un): support the longest + path in sockaddr_un. + (sock_s_unpack_sockaddr_un): ditto. + (sock_s_gethostbyaddr): unused variable removed. + + * ext/socket/unixsocket.c (rsock_init_unixsock): support the longest + path in sockaddr_un. + + * ext/socket/rubysocket.h (rsock_unixpath_str): declared. + (rsock_unixpath): removed. + + * test/socket/test_unix.rb: comment out test_nul because abstract unix + sockets may contain NULs. + Thu Apr 26 01:32:33 2012 CHIKANAGA Tomoyuki * test/optparse/test_summary.rb (test_summary_containing_space): add diff --git a/ext/socket/raddrinfo.c b/ext/socket/raddrinfo.c index f2e0cddc3e..8c409f181f 100644 --- a/ext/socket/raddrinfo.c +++ b/ext/socket/raddrinfo.c @@ -421,20 +421,25 @@ rsock_ipaddr(struct sockaddr *sockaddr, int norevlookup) } #ifdef HAVE_SYS_UN_H -const char* -rsock_unixpath(struct sockaddr_un *sockaddr, socklen_t len) +VALUE +rsock_unixpath_str(struct sockaddr_un *sockaddr, socklen_t len) { - if (sockaddr->sun_path < (char*)sockaddr + len) - return sockaddr->sun_path;
