2020-10-21Ractor.make_shareable(obj)Koichi Sasada
Introduce new method Ractor.make_shareable(obj) which tries to make obj shareable object. Protocol is here. (1) If obj is shareable, it is shareable. (2) If obj is not a shareable object and if obj can be shareable object if it is frozen, then freeze obj. If obj has reachable objects (rs), do rs.each{|o| Ractor.make_shareable(o)} recursively (recursion is not Ruby-level, but C-level). (3) Otherwise, raise Ractor::Error. Now T_DATA is not a shareable object even if the object is frozen. If the method finished without error, given obj is marked as a sharable object. To allow makng a shareable frozen T_DATA object, then set `RUBY_TYPED_FROZEN_SHAREABLE` as type->flags. On default, this flag is not set. It means user defined T_DATA objects are not allowed to become shareable objects when it is frozen. You can make any object shareable by setting FL_SHAREABLE flag, so if you know that the T_DATA object is shareable (== thread-safe), set this flag, at creation time for example. `Ractor` object is one example, which is not a frozen, but a shareable object.

On Solaris, it seems to access ENV in ``, so skip it now. ``` stderr output is not empty Exception `NameError' at bootstraptest.tmp.rb:7 - can not access non-sharable objects in constant Object::ENV by non-main Ractor. #<Thread:0x0044cdf0 run> terminated with exception (report_on_exception is true): bootstraptest.tmp.rb:7:in ``': can not access non-sharable objects in constant Object::ENV by non-main Ractor.

2020-10-20ObjectSpace.each_object with RactorsKoichi Sasada
Unshareable objects should not be touched from multiple ractors so ObjectSpace.each_object should be restricted. On multi-ractor mode, ObjectSpace.each_object only iterates shareable objects. [Feature #17270] Notes: Merged: https://github.com/ruby/ruby/pull/3672
2020-10-20Some global variables can be accessed from ractorsKoichi Sasada
Some global variables should be used from non-main Ractors. [Bug #17268] ```ruby # ractor-local (derived from created ractor): debug '$DEBUG' => $DEBUG, '$-d' => $-d, # ractor-local (derived from created ractor): verbose '$VERBOSE' => $VERBOSE, '$-w' => $-w, '$-W' => $-W, '$-v' => $-v, # process-local (readonly): other commandline parameters '$-p' => $-p, '$-l' => $-l, '$-a' => $-a, # process-local (readonly): getpid '$$' => $$, # thread local: process result '$?' => $?, # scope local: match '$~' => $~.inspect, '$&' => $&, '$`' => $`, '$\'' => $', '$+' => $+, '$1' => $1, # scope local: last line '$_' => $_, # scope local: last backtrace '$@' => $@, '$!' => $!, # ractor local: stdin, out, err '$stdin' => $stdin.inspect, '$stdout' => $stdout.inspect, '$stderr' => $stderr.inspect, ``` Notes: Merged: https://github.com/ruby/ruby/pull/3670
2020-10-14sync generic_ivtblKoichi Sasada
generic_ivtbl is a process global table to maintain instance variables for non T_OBJECT/T_CLASS/... objects. So we need to protect them for multi-Ractor exection. Hint: we can make them Ractor local for unshareable objects, but now it is premature optimization. Notes: Merged: https://github.com/ruby/ruby/pull/3655
2020-10-14sync enc_table and rb_encoding_listKoichi Sasada
enc_table which manages Encoding information. rb_encoding_list also manages Encoding objects. Both are accessed/modified by ractors simultaneously so that they should be synchronized. For enc_table, this patch introduced GLOBAL_ENC_TABLE_ENTER/LEAVE/EVAL to access this table with VM lock. To make shortcut, three new global variables global_enc_ascii, global_enc_utf_8, global_enc_us_ascii are also introduced. For rb_encoding_list, we split it to rb_default_encoding_list (256 entries) and rb_additional_encoding_list. rb_default_encoding_list is fixed sized Array so we don't need to synchronized (and most of apps only needs it). To manage 257 or more encoding objects, they are stored into rb_additional_encoding_list. To access rb_additional_encoding_list., VM lock is needed.

Matz want to try to freeze all Range objects. [Feature #15504] Notes: Merged: https://github.com/ruby/ruby/pull/3583
2020-09-25prohibi method call by defined_method in other racotrsKoichi Sasada
We can not call a non-isolated Proc in multiple ractors. Notes: Merged: https://github.com/ruby/ruby/pull/3584
2020-09-25Range is based on Struct.Koichi Sasada
Range can be shareable because it is implemented by Struct. Notes: Merged: https://github.com/ruby/ruby/pull/3580
2020-09-25Frozen Struct can be shareable.Koichi Sasada
A frozen Struct object which refers to shareable objects should be shareable. Notes: Merged: https://github.com/ruby/ruby/pull/3580

2020-09-25Ractor.yield should raise if out-port is closedKoichi Sasada
Ractor.yield should raise Ractor::ClosedError if current Ractor's outgoing-port is closed. Notes: Merged: https://github.com/ruby/ruby/pull/3578
2020-09-25frozen T_OBJECT can be shareable.Koichi Sasada
If an T_OBJECT object is frozen and all ivars are shareable, the object should be shareable. Notes: Merged: https://github.com/ruby/ruby/pull/3575
2020-09-25Ractor#close_outgoping cancel Ractor.yieldKoichi Sasada
Ractor#close_outgoing should cancel waiting Ractor.yield. However, yield a value by the Ractor's block should not cancel (to recognize terminating Ractor, introduce rb_ractor_t::yield_atexit flag). Notes: Merged: https://github.com/ruby/ruby/pull/3572

2020-09-04don't use toplevel returnKoichi Sasada
Toplevel return is supported after Ruby 2.4, so don't use it for older BASERUBY.
2020-09-03skip Ractor tests on Compiler testsKoichi Sasada
This implementation has memory corruption errors so and it causes BUG on rare occasions. This commit skips suspect tests on Github actions Compiler tests. Notes: Merged: https://github.com/ruby/ruby/pull/3365
2020-09-03Introduce Ractor mechanism for parallel executionKoichi Sasada
This commit introduces Ractor mechanism to run Ruby program in parallel. See doc/ractor.md for more details about Ractor. See ticket [Feature #17100] to see the implementation details and discussions. [Feature #17100] This commit does not complete the implementation. You can find many bugs on using Ractor. Also the specification will be changed so that this feature is experimental. You will see a warning when you make the first Ractor with `Ractor.new`. I hope this feature can help programmers from thread-safety issues. Notes: Merged: https://github.com/ruby/ruby/pull/3365
