* [Feature #18045] Implement size classes for GCPeter Zhu2021-08-251-1/+1
| | | | | | | | | This commits implements size classes in the GC for the Variable Width Allocation feature. Unless `USE_RVARGC` compile flag is set, only a single size class is created, maintaining current behaviour. See the redmine ticket for more details.

* [Feature #18045] Remove T_PAYLOADPeter Zhu2021-08-251-4/+0
| | | | | | | This commit removes T_PAYLOAD since the new VWA implementation no longer requires T_PAYLOAD types. Co-authored-by: Aaron Patterson <tenderlove@ruby-lang.org>

* ast.c: Rename "save_script_lines" to "keep_script_lines"Yusuke Endoh2021-08-201-1/+1
| | | | | | | ... as per ko1's preference. He is preparing to extend this feature to ISeq for his new debugger. He prefers "keep" to "save" for this wording. This API is internal and not included in any released version, so I change it in advance.

| | | | | | Make `RUBY_VERSION_SINCE` and `RUBY_VERSION_BEFORE` to take major and minor numbers so usable also in preprocessor directives. Old macros are renamed with "STRING".

| | | | | | | | | | | ndigits higher than 14 can result in values that are slightly too large due to floating point limitations. Converting to rational for the calculation and then back to float fixes these issues. Fixes [Bug #14635] Fixes [Bug #17183] Co-authored by: Yusuke Endoh <mame@ruby-lang.org>

| | | | | | | When a Ractor is removed, the freelist in the Ractor cache is not returned to the GC, leaving the freelist permanently lost. This commit recycles the freelist when the Ractor is destroyed, preventing a memory leak from occurring.

GitHub PR #4340. This change implements a cache for class variables. Previously there was no cache for cvars. Cvar access is slow due to needing to travel all the way up th ancestor tree before returning the cvar value. The deeper the ancestor tree the slower cvar access will be. The benefits of the cache are more visible with a higher number of included modules due to the way Ruby looks up class variables. The benchmark here includes 26 modules and shows with the cache, this branch is 6.5x faster when accessing class variables. ``` compare-ruby: ruby 3.1.0dev (2021-03-15T06:22:34Z master 9e5105c) [x86_64-darwin19] built-ruby: ruby 3.1.0dev (2021-03-15T12:12:44Z add-cache-for-clas.. c6be009) [x86_64-darwin19] | |compare-ruby|built-ruby| |:--------|-----------:|---------:| |vm_cvar | 5.681M| 36.980M| | | -| 6.51x| ``` Benchmark.ips calling `ActiveRecord::Base.logger` from within a Rails application.

* Make it possible to get AST::Node from Thread::Backtrace::LocationYusuke Endoh2021-06-181-0/+2
| | | | | | | | | RubyVM::AST.of(Thread::Backtrace::Location) returns a node that corresponds to the location. Typically, the node is a method call, but not always. This change also includes iseq's dump/load support of node_ids for each instructions.
* ast.rb: RubyVM::AST.parse and .of accepts `save_script_lines: true`Yusuke Endoh2021-06-181-0/+1
| | | | | | | This option makes the parser keep the original source as an array of the original code lines. This feature exploits the mechanism of `SCRIPT_LINES__` but records only the specified code that is passed to RubyVM::AST.of or .parse, instead of recording all parsed program texts.

* cdhash_cmp: can also take complex卜部昌平2021-05-121-0/+1
| | | | There are complex literals `123i`, which can also be a case condition.
* cdhash_cmp: can take rational literals卜部昌平2021-05-121-0/+1
| | | | | | | Rational literals are those integers suffixed with `r`. They tend to be a part of more complex expressions like `123/456r`, but in theory they can live alone. When such "bare" rational literals are passed to case-when branch, we have to take care of them. Fixes [Bug #17854]

* node.c (rb_ast_new): imemo_ast is WB-unprotectedYusuke Endoh2021-04-261-0/+1
| | | | | | | | | | | | | | | | | | Previously imemo_ast was handled as WB-protected which caused a segfault of the following code: # shareable_constant_value: literal M0 = {} M1 = {} ... M100000 = {} My analysis is here: `shareable_constant_value: literal` creates many Hash instances during parsing, and add them to node_buffer of imemo_ast. However, the contents are missed because imemo_ast is incorrectly WB-protected. This changeset makes imemo_ast as WB-unprotected.

| | | | | | | | If called with an autoloaded encoding that was not yet initialized, `rb_enc_interned_str` would crash with a NULL pointer exception. See: https://github.com/ruby/ruby/pull/4119#issuecomment-800189841
