2015-12-08* introduce new ISeq binary format serializer/de-serializerko1
and a pre-compilation/runtime loader sample. [Feature #11788] * iseq.c: add new methods: * RubyVM::InstructionSequence#to_binary_format(extra_data = nil) * RubyVM::InstructionSequence.from_binary_format(binary) * RubyVM::InstructionSequence.from_binary_format_extra_data(binary) * compile.c: implement body of this new feature. * load.c (rb_load_internal0), iseq.c (rb_iseq_load_iseq): call RubyVM::InstructionSequence.load_iseq(fname) with loading script name if this method is defined. We can return any ISeq object as a result value. Otherwise loading will be continue as usual. This interface is not matured and is not extensible. So that we don't guarantee the future compatibility of this method. Basically, you should'nt use this method. * iseq.h: move ISEQ_MAJOR/MINOR_VERSION (and some definitions) from iseq.c. * encoding.c (rb_data_is_encoding), internal.h: added. * vm_core.h: add several supports for lazy load. * add USE_LAZY_LOAD macro to specify enable or disable of this feature. * add several fields to rb_iseq_t. * introduce new macro rb_iseq_check(). * insns.def: some check for lazy loading feature. * vm_insnhelper.c: ditto. * proc.c: ditto. * vm.c: ditto. * test/lib/iseq_loader_checker.rb: enabled iff suitable environment variables are provided. * test/runner.rb: enable lib/iseq_loader_checker.rb. * sample/iseq_loader.rb: add sample compiler and loader. $ ruby sample/iseq_loader.rb [dir] will compile all ruby scripts in [dir]. With default setting, this compile creates *.rb.yarb files in same directory of target .rb scripts. $ ruby -r sample/iseq_loader.rb [app] will run with enable to load compiled binary data. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@52949 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2015-12-06introduce rb_autoload_str to replace rb_autoloadnormal
rb_autoload_str may be safer by preventing premature GC. It can also be more efficient by passing a pre-frozen string that can be deduped using rb_fstring. Common autoload callers (e.g. rubygems, rdoc) already use string literals as the file argument. There seems to be no reason to expose rb_autoload_str to the public C API since autoload is not performance-critical. Applications may declare autoloads in Ruby code or via rb_funcall; so merely deprecate rb_autoload without exposing rb_autoload_str to new users.

2015-11-23fiddle: release GVL for ffi_callnormal
Some external functions I wish to call may take a long time and unnecessarily block other threads. This may lead to performance regressions for fast functions as releasing/acquiring the GVL is not cheap, but can improve performance for long-running functions in multi-threaded applications. This also means we must reacquire the GVL when calling Ruby-defined callbacks for Fiddle::Closure, meaning we must detect whether the current thread has the GVL by exporting ruby_thread_has_gvl_p in internal.h * ext/fiddle/function.c (struct nogvl_ffi_call_args): new struct for GVL release (nogvl_ffi_call): new function (function_call): adjust for GVL release [ruby-core:71642] [Feature #11607] * ext/fiddle/closure.c (struct callback_args): new struct for GVL acquire (with_gvl_callback): adjusted original callback function (callback): wrapper for conditional GVL acquire * ext/fiddle/depend: add dependencies * ext/fiddle/extconf.rb: include top_srcdir for internal.h * internal.h (ruby_thread_has_gvl_p): expose for fiddle * vm_core.h (ruby_thread_has_gvl_p): moved to internal.h * test/fiddle/test_function.rb (test_nogvl_poll): new test git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@52723 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2015-10-17* ruby.c (open_load_file): reset O_NONBLOCK after open.kosaki
Even if S_ISREG() is true, the file may be file on FUSE filesystem or something. We can't assume O_NONBLOCK is safe. Moreover, we should wait if the path is point to FIFO. That's FIFO semantics. GVL should be transparent from ruby script. Thus, just reopen without O_NONBLOCK for filling the requirements. [Bug #11060][Bug #11559] * ruby.c (loadopen_func): new for the above. * file.c (ruby_is_fd_loadable): new. for checks loadable file type of not. * file.c (rb_file_load_ok): use ruby_is_fd_loadble() * internal.h: add ruby_is_fd_loadble() * common.mk: now, ruby.o depend on thread.h. * test/ruby/test_require.rb (TestRequire#test_loading_fifo_threading_success): new test. This test successful case that loading from FIFO. * test/ruby/test_require.rb (TestRequire#test_loading_fifo_threading_raise): rename from test_loading_fifo_threading. You souldn't rescue an exception if you test raise or not. Moreover, this case should be caught IOError because load(FIFO) should be blocked until given any input. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@52151 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

[Feature #11420] This table only manage ID->VALUE table to reduce overhead of st. Some functions prefixed rb_id_table_* are provided. * id_table.c: implement rb_id_table_*. There are several algorithms to implement it. Now, there are roughly 4 types: * st * array * hash (implemented by Yura Sokolov) * mix of array and hash The macro ID_TABLE_IMPL can choose implementation. You can see detailes about them at the head of id_table.c. At the default, I choose 34 (mix of list and hash). This is not final decision. Please report your suitable parameters or your data structure. * symbol.c: introduce rb_id_serial_t and rb_id_to_serial() to represent ID by serial number. * internal.h: use id_table for method tables. * class.c, gc.c, marshal.c, vm.c, vm_method.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51541 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2015-07-21* make rb_iseq_t T_IMEMO object (type is imemo_iseq).ko1
All contents of previous rb_iseq_t is in rb_iseq_t::body. Remove rb_iseq_t::self because rb_iseq_t is an object. RubyVM::InstructionSequence is wrapper object points T_IMEMO/iseq. So RubyVM::ISeq.of(something) method returns different wrapper objects but they point the same T_IMEMO/iseq object. This patch is big, but most of difference is replacement of iseq->xxx to iseq->body->xxx. (previous) rb_iseq_t::compile_data is also located to rb_iseq_t::compile_data. It was moved from rb_iseq_body::compile_data. Now rb_iseq_t has empty two pointers. I will split rb_iseq_body data into static data and dynamic data. * compile.c: rename some functions/macros. Now, we don't need to separate iseq and iseqval (only VALUE). * eval.c (ruby_exec_internal): `n' is rb_iseq_t (T_IMEMO/iseq). * ext/objspace/objspace.c (count_imemo_objects): count T_IMEMO/iseq. * gc.c: check T_IMEMO/iseq. * internal.h: add imemo_type::imemo_iseq. * iseq.c: define RubyVM::InstructionSequnce as T_OBJECT. Methods are implemented by functions named iseqw_.... * load.c (rb_load_internal0): rb_iseq_new_top() returns rb_iseq_t (T_IMEMO/iesq). * method.h (rb_add_method_iseq): accept rb_iseq_t (T_IMEMO/iseq). * vm_core.h (GetISeqPtr): removed because it is not T_DATA now. * vm_core.h (struct rb_iseq_body): remove padding for [Bug #10037][ruby-core:63721]. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51327 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

If the given FD is the same as one of the reserved FDs, the reserved FD number is internally changed. It returns -1 when error. Otherwise, returns 0. It also returns 0 if there is no need to change reserved FD number. * thread_win32.c (rb_divert_reserved_fd): always returns 0 because of no reserved FDs. * internal.h (rb_divert_reserved_fd): prototype declaration.

* internal.h, iseq.c (rb_iseq_klass): remove it because rb_iseq_t::klass is removed. * vm_insnhelper.c (vm_super_outside): do not see cfp->iseq, but check callable method entry on a frame. This fix simplify the logic to search super class. * test/ruby/test_method.rb: support super() from Proc. Now, [Bug #4881] and [Bug #3136] was solved. * proc.c (rb_mod_define_method): catch up this change. * vm.c (vm_define_method): ditto. * vm_backtrace.c (rb_profile_frames): now, each `frame' objects are rb_callable_method_entry_t data or iseq VALUEs. This fix introduce minor compatibility issue that rb_profile_frame_label() always returns rb_profile_frame_base_label(). * test/-ext-/debug/test_profile_frames.rb: catch up this change. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51166 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2015-07-03* method.h: introduce rb_callable_method_entry_t to removeko1
rb_control_frame_t::klass. [Bug #11278], [Bug #11279] rb_method_entry_t data belong to modules/classes. rb_method_entry_t::owner points defined module or class. module M def foo; end end In this case, owner is M. rb_callable_method_entry_t data belong to only classes. For modules, MRI creates corresponding T_ICLASS internally. rb_callable_method_entry_t can also belong to T_ICLASS. rb_callable_method_entry_t::defined_class points T_CLASS or T_ICLASS. rb_method_entry_t data for classes (not for modules) are also rb_callable_method_entry_t data because it is completely same data. In this case, rb_method_entry_t::owner == rb_method_entry_t::defined_class. For example, there are classes C and D, and incldues M, class C; include M; end class D; include M; end then, two T_ICLASS objects for C's super class and D's super class will be created. When C.new.foo is called, then M#foo is searcheed and rb_callable_method_t data is used by VM to invoke M#foo. rb_method_entry_t data is only one for M#foo. However, rb_callable_method_entry_t data are two (and can be more). It is proportional to the number of including (and prepending) classes (the number of T_ICLASS which point to the module). Now, created rb_callable_method_entry_t are collected when the original module M was modified. We can think it is a cache. We need to select what kind of method entry data is needed. To operate definition, then you need to use rb_method_entry_t. You can access them by the following functions. * rb_method_entry(VALUE klass, ID id); * rb_method_entry_with_refinements(VALUE klass, ID id); * rb_method_entry_without_refinements(VALUE klass, ID id); * rb_resolve_refined_method(VALUE refinements, const rb_method_entry_t *me); To invoke methods, then you need to use rb_callable_method_entry_t which you can get by the following APIs corresponding to the above listed functions. * rb_callable_method_entry(VALUE klass, ID id); * rb_callable_method_entry_with_refinements(VALUE klass, ID id); * rb_callable_method_entry_without_refinements(VALUE klass, ID id); * rb_resolve_refined_method_callable(VALUE refinements, const rb_callable_method_entry_t *me); VM pushes rb_callable_method_entry_t, so that rb_vm_frame_method_entry() returns rb_callable_method_entry_t. You can check a super class of current method by rb_callable_method_entry_t::defined_class. * method.h: renamed from rb_method_entry_t::klass to rb_method_entry_t::owner. * internal.h: add rb_classext_struct::callable_m_tbl to cache rb_callable_method_entry_t data. We need to consider abotu this field again because it is only active for T_ICLASS. * class.c (method_entry_i): ditto. * class.c (rb_define_attr): rb_method_entry() does not takes defiend_class_ptr. * gc.c (mark_method_entry): mark RCLASS_CALLABLE_M_TBL() for T_ICLASS. * cont.c (fiber_init): rb_control_frame_t::klass is removed. * proc.c: fix `struct METHOD' data structure because rb_callable_method_t has all information. * vm_core.h: remove several fields. * rb_control_frame_t::klass. * rb_block_t::klass. And catch up changes. * eval.c: catch up changes. * gc.c: ditto. * insns.def: ditto. * vm.c: ditto. * vm_args.c: ditto. * vm_backtrace.c: ditto. * vm_dump.c: ditto. * vm_eval.c: ditto. * vm_insnhelper.c: ditto. * vm_method.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51126 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
