00ba9fa2 - Define `_GNU_SOURCE` properly/consistently per autoconf

Mon, 25 Feb 2019 19:59:15 +0000

Define `_GNU_SOURCE` properly/consistently per autoconfAlthough `_GNU_SOURCE` can be defined as an arbitrary #define per theglibc docs [1], it's best to define it in a manner consistent with the waythat autoconf defines it, i.e., `1`.While this shouldn't matter in most cases, it does when the headers fromother projects follow the poorly defined GNU convention implemented byautoconf and are included after the libevent's util.h header. An examplefailure with clang, similar to the failure I encountered, is as follows:```$ printf "#define _GNU_SOURCE\n#define _GNU_SOURCE 1" | clang -c -x c -:2:9: warning: '_GNU_SOURCE' macro redefined [-Wmacro-redefined] ^:1:9: note: previous definition is here ^1 warning generated.```This happened when compiling python [2] with a stale homebrew util.h file fromlibevent (which admittedly would not happen in a correct libevent install, as theheader should be installed under /usr/local/include/event2/util.h). However, ifboth headers had been combined (which is more likely), it would have failed asshown above.Removing the ad hoc definition unbreaks compiling python's pyconfig.h.in headerwhen included after util.h from libevent.1. http://www.gnu.org/software/libc/manual/html_node/Feature-Test-Macros.html2. https://github.com/python/cpython/blob/master/configure.ac#L126Closes: #773 (cherry-picked)Signed-off-by: Enji Cooper (cherry picked from commit 5f87be42f0ae0126938624a1419a572607078217) List of files: /libevent-2.1.12/include/event2/util.h

e66078a0 - Eliminate fd conversion warnings and introduce EVUTIL_INVALID_SOCKET (windows)

Tue, 29 Jan 2019 18:12:33 +0000

Eliminate fd conversion warnings and introduce EVUTIL_INVALID_SOCKET (windows)windows has intptr_t instead of regular int.Also tt_fd_op() had been introduced, since we cannot use tt_int_op() forcomparing fd, since it is not always int.(cherry picked from commit b29207dceee33832bb28ab103a833df6a2fd29d3) List of files: /libevent-2.1.12/include/event2/util.h

Sun, 28 Oct 2018 15:11:22 +0000

Check existence of IPV6_V6ONLY in evutil_make_listen_socket_ipv6only() (mingw32)MinGW 32-bit 5.3.0 does not defines it and our appveyour [1] buildreports this instantly: evutil.c: In function 'evutil_make_listen_socket_ipv6only': evutil.c:392:40: error: 'IPV6_V6ONLY' undeclared (first use in this function) return setsockopt(sock, IPPROTO_IPV6, IPV6_V6ONLY, (void*) &one, [1]: https://www.appveyor.com/docs/windows-images-software/#mingw-msys-cygwinAnother solution will be to use mingw64 which has it, but I guess we dowant that #ifdef anyway.(cherry picked from commit 23e79fd764b9f36f560d470f0fb60295dd942ac2) List of files: /libevent-2.1.12/include/event2/util.h

ba148796 - listener: ipv6only socket bind support

Mon, 04 Jun 2018 13:43:34 +0000

listener: ipv6only socket bind supportAccording to RFC3493 and most Linux distributions, default value is towork in IPv4-mapped mode. If there is a requirement to bind same porton same ip addresses but different handlers for both IPv4 and IPv6,it is required to set IPV6_V6ONLY socket option to be sure that thecode works as expected without affected by bindv6only sysctl settingin system.See an example working with this patch:https://gist.github.com/demirten/023008a63cd966e48b0ebcf9af7fc113Closes: #640 (cherry-pick)(cherry picked from commit 387d91f9ab95df8ac3d7bb58493310ad4a377dcf) List of files: /libevent-2.1.12/include/event2/util.h

Wed, 16 Dec 2015 01:17:36 +0000

The Windows socket type is defined as SOCKET.Under the hood it's an unsigned rather than a signed type and whilst Ccompilers are largely happy with this C++ compilers tend to be fussyabout class function signatures which makes C++ usage of libeventproblematic.

043ae748 - Fix garbage value in socketpair util function, stdint?

Mon, 11 May 2015 16:06:01 +0000

Fix garbage value in socketpair util function, stdint?* Fixed an issue with evutil_ersatz_socketpair_, listen_addr could all be compared against with agarbage values. So just memset it before using it anywhere.* Nick might punch me in the face, but if we have stdint.h; (as in EVENT__HAVE_STDINT_H is defined), might as well use those instead of the manual [U]INT[X}_MAX/MIN muck in there now.
