hacks to thread_pthread.c git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@35674 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-05-17Imports Ruby's port to NativeClient (a.k.a NaCl).yugui
Patch by Google Inc. [ruby-core:45073]. * configure.in (RUBY_NACL): New M4 func to configure variables for NaCl. (RUBY_NACL_CHECK_PEPPER_TYPES): New M4 func to check the old names of Pepper interface types. (BTESTRUBY): New variable to specify which ruby should be run on "make btest". NaCl can run the built binary by sel_ldr, but it need rbconfig.rb. So this variable is distinguished from $MINIRUBY. * thread_pthread.c: Disabled some features on NaCl. * io.c: ditto. * process.c: ditto. * signal.c: ditto. * file.c: ditto. * missing/flock.c: ditto. * nacl/pepper_main.c: An example implementation of Pepper application that embeds Ruby. * nacl/example.html: An example of web page that uses the Pepper application. * nacl/nacl-config.rb: Detects variants of NaCl SDK. * nacl/GNUmakefile.in: Makefile template for NaCl specific build process. * nacl/package.rb: script for packaging a NaCl-Ruby embedding application. * nacl/reate_nmf.rb: Wrapper script of create_nmf.py * dln.c (dln_load): Added a hack to call on NaCl. * util.c (ruby_getcwd): Path to the current directort is not available on NaCl. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@35672 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2011-06-27* thread_pthread.c: Stop polling in the timer thread when there areko1
no waiting thread. If there are 2 or more runnable threads, the timer thread does polling. Avoid polling makes power save for several computers (0.2W per a Ruby process, when I measured). If outside-event such as signal or Thread#kill was occuerred when the timer thread does not do polling, then wake-up the timer thread using communication-pipe (the timer thread waits this communication-pipe with select(2)). The discussion about this modification can be found from the post [ruby-core:33456] and other related posts. Note that Eric Wong and KOSAKI Motohiro give us the huge contributions for this modification. Thanks. * thread_pthread.c (rb_thread_wakeup_timer_thread): add a function.
