* spec/ruby/core/io/*_spec.rb: explain MJIT failuresnormal2018-12-032-6/+6
| | | | | | | | | | | | | These random failures happen because FD number allocation is not predictable when multiple threads are running (since MJIT thread is opening/closing files all the time). Real-world code practically never relies on predictable FD number allocation (because much real-world code is multi-threaded); so it's highly unlikely there'll be any breakage to the user. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66159 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* io + socket: make pipes and sockets nonblocking by defaultnormal2018-11-222-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: https://bugs.ruby-lang.org/issues/13618 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.

* spec/ruby/core/io/select_spec.rb: workaround stuck IO.selectnormal2018-08-201-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under pipe page memory pressure on Linux, a pipe may only be created with a single buffer[1]. And as of Linux v4.18, the fs/pipe.c::pipe_poll callback does not account for merging done in fs/pipe::pipe_write; only the number of usable buffers in the pipe. Thus it is possible for a pipe to be writable (if only by a small amount) despite IO.select saying it is not. With the default 16384 /proc/sys/fs/pipe-user-pages-soft value and the pipe having 16 pages of buffers, this issue is trivially reproducible by creating 1024 pipes in a background process before running the spec: $ ulimit -n 2053 # or something higher $ ./miniruby -e '1024.times.map { IO.pipe }; sleep' & $ make test-spec MSPECOPT=spec/ruby/core/io/select_spec.rb So, we create a new pipe we never write to for testing writability of IO.select. This may cause the test to fail with ENFILE on an overloaded system, but at least that's an obvious failure (unlike having a test get stuck). This should reduce failures on our overloaded CI machines: http://ci.rvm.jp/results/trunk-nopara@silicon-docker/1239426 [1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/fs/pipe.c?h=v4.18#n642 git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64478 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
