2020-12-07Revert getaddrinfo_a()Masaki Matsushita
getaddrinfo_a() gets stuck after fork(). To avoid this, we need 1 second sleep to wait for internal worker threads of getaddrinfo_a() to be finished, but that is unacceptable. [Bug #17220] [Feature #17134] [Feature #17187]

2020-08-27Make Socket.getaddrinfo interruptible (#2827)Kir Shatrov
Before, Socket.getaddrinfo was using a blocking getaddrinfo(3) call. That didn't allow to wrap it into Timeout.timeout or interrupt the thread in any way. Combined with the default 10 sec resolv timeout on many Unix systems, this can have a very noticeable effect on production Ruby apps being not resilient to DNS outages and timing out name resolution, and being unable to fail fast even with Timeout.timeout. Since we already have support for getaddrinfo_a(3), the async version of getaddrinfo, we should be able to make Socket.getaddrinfo leverage that when getaddrinfo_a version is available in the system (hence #ifdef HAVE_GETADDRINFO_A).

There seems to be a compatibility problems with Rails + Rack::Deflater; so we revert this incompatibility. This effectively reverts r65922; but keeps the bugfixes to better support non-blocking sockets and pipes for future use.

2018-11-22socket: disable nonblocking-by-default on win32normal
Perhaps this fixes test failures reported by Greg and k0kubun. However, the failure of certain tests to handle non-blocking I/O seems to indicate pre-existing problems on win32 platforms. Somebody knowledgeable about win32 should be able to fix it. [ruby-core:89973] [ruby-core:89976] [ruby-core:89977] [Bug #14968] git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-11-22io + socket: make pipes and sockets nonblocking by defaultnormal
All normal Ruby IO methods (IO#read, IO#gets, IO#write, ...) are all capable of appearing to be "blocking" when presented with a file description with the O_NONBLOCK flag set; so there is little risk of incompatibility within Ruby-using programs. The biggest compatibility risk is when spawning external programs. As a result, stdin, stdout, and stderr are now always made blocking before exec-family calls. This change will make an event-oriented MJIT usable if it is waiting on pipes on POSIX_like platforms. It is ALSO necessary to take advantage of (proposed lightweight concurrency (aka "auto-Fiber") or any similar proposal for network concurrency: Named-pipe (FIFO) are NOT yet non-blocking by default since they are rarely-used and may introduce compatibility problems and extra syscall overhead for a common path. Please revert this commit if there are problems and if I am afk since I am afk a lot, lately. [ruby-core:89950] [Bug #14968] git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-10-21Deprecation document for gethostbyname,gethostbyaddr.akr
[Feature #13097] I confirmed current ruby (Ruby 2.4 and trunk) uses gethostbyname() and gethostbyaddr(). Socket.gethostbyname uses getaddrinfo() and gethostbyname(). Socket.gethostbyaddr uses gethostbyaddr(). Socket.gethostbyname uses gethostbyname() to obtain alias hostnames. RFC 3493 defines getaddrinfo()/getnameinfo() and describes the problems of gethostbyname()/gethostbyaddr(). The problems are difficult protocol handling and thread-unsafety. Since Ruby has GVL, the thread-unsafety doesn't cause wrong result. But it may block other threads until finishing DNS query. Socket.gethostbyname has the protocol handling problem. It returns only one address family: ``` % ruby -rpp -rsocket -e 'pp Socket.gethostbyname("")' ["", [], 10, " \x01\x02\x00\r\xFF\xFF\xF1\x02\x16>\xFF\xFEKe\x1C", "\xCB\xB2\x89:"] ``` has one IPv6 address and one IPv4 address. But Socket.gethostbyname returns only one address family, 10 (AF_INET6), which is the address family of the first address. Also, Socket.gethostbyname and Socket.gethostbyaddr uses 4-bytes binary IPv4 address and 16-bytes binary IPv6 address. This is not usual in other socket API in Ruby. (Most socket API uses binary sockaddr string or Addrinfo object) I think Socket.gethostbyname and Socket.gethostbyaddr are too far from recommendable API. So, I added deprecation description for documents for them. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
