In vm_call_method_each_type, check for c_call and c_return events before dispatching to vm_call_ivar and vm_call_attrset. With this approach, the call cache will still dispatch directly to those functions, so this change will only decrease performance for the first (uncached) call, and even then, the performance decrease is very minimal. This approach requires that we clear the call caches when tracing is enabled or disabled. The approach currently switches all vm_call_ivar and vm_call_attrset call caches to vm_call_general any time tracing is enabled or disabled. So it could theoretically result in a slowdown for code that constantly enables or disables tracing. This approach does not handle targeted tracepoints, but from my testing, c_call and c_return events are not supported for targeted tracepoints, so that shouldn't matter. This includes a benchmark showing the performance decrease is minimal if detectable at all. Fixes [Bug #16383] Fixes [Bug #10470] Co-authored-by: Takashi Kokubun <takashikkbn@gmail.com> |

What's Ruby
Ruby is an interpreted object-oriented programming language often used for web development. It also offers many scripting features to process plain text and serialized files, or manage system tasks. It is simple, straightforward, and extensible.
Features of Ruby
- Simple Syntax
- Normal Object-oriented Features (e.g. class, method calls)
- Advanced Object-oriented Features (e.g. mix-in, singleton-method)
- Operator Overloading
- Exception Handling
- Iterators and Closures
- Garbage Collection
- Dynamic Loading of Object Files (on some architectures)
- Highly Portable (works on many Unix-like/POSIX compatible platforms as well as Windows, macOS, etc.) cf. https://github.com/ruby/ruby/blob/master/doc/contributing.rdoc#label-Platform+Maintainers
How to get Ruby
For a complete list of ways to install Ruby, including using third-party tools like rvm, see:
https://www.ruby-lang.org/en/downloads/
Git
The mirror of the Ruby source tree can be checked out with the following command:
$ git clone https://github.com/ruby/ruby.git
There are some other branches under development. Try the following command to see the list of branches:
$ git ls-remote https://github.com/ruby/ruby.git
You may also want to use https://git.ruby-lang.org/ruby.git (actual master of Ruby source) if you are a committer.
Subversion
Stable branches for older Ruby versions can be checked out with also the following command:
$ svn co https://svn.ruby-lang.org/repos/ruby/branches/ruby_2_6/ ruby
Try the following command to see the list of branches:
$ svn ls https://svn.ruby-lang.org/repos/ruby/branches/

Requirements to build from repository
- GNU or BSD make
- C99 compiler
- autoconf 2.67 or higher
- automake 1.15 or higher
- bison 2.3 or higher
- Ruby 2.2 or higher
When building from a released version, only a C99 compiler and GNU or BSD make is required.
How to compile and install
-
If you want to use Microsoft Visual C++ to compile Ruby, read win32/README.win32 instead of this document.
-
Run
./autogen.shto generate configure, when you build the source checked out from the Git repository. -
Run
./configure, which will generateconfig.handMakefile.Some C compiler flags may be added by default depending on your environment. Specify
optflags=..andwarnflags=..as necessary to override them. -
Edit
include/ruby/defines.hif you need. Usually this step will not be needed. -
Optional: Remove comment mark(
#) before the module names fromext/Setup.This step is only necessary if you want to link modules statically.
If you don't want to compile dynamic extensions (probably on architectures which do not allow dynamic loading), remove comment mark from the line "
#option nodynamic" inext/Setup.Usually this step will not be needed.
-
Run
make.- On Mac, set RUBY_CODESIGN environment variable with a signing identity.
It uses the identity to sign
rubybinary. See also codesign(1).
- On Mac, set RUBY_CODESIGN environment variable with a signing identity.
It uses the identity to sign
-
Optionally, run '
make check' to check whether the compiled Ruby interpreter works well. If you see the message "check succeeded", your Ruby works as it should (hopefully). -
Run '
make install'.This command will create the following directories and install files into them.
${DESTDIR}${prefix}/bin${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}${DESTDIR}${prefix}/lib${DESTDIR}${prefix}/lib/ruby${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}${DESTDIR}${prefix}/lib/ruby/site_ruby${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}${DESTDIR}${prefix}/lib/ruby/vendor_ruby${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}${DESTDIR}${prefix}/share/man/man1${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system
If Ruby's API version is 'x.y.z', the
${MAJOR}is 'x', the${MINOR}is 'y', and the${TEENY}is 'z'.NOTE: teeny of the API version may be different from one of Ruby's program version
You may have to be a super user to install Ruby.
If you fail to compile Ruby, please send the detailed error report with the error log and machine/OS type, to help others.
Some extension libraries may not get compiled because of lack of necessary
external libraries and/or headers, then you will need to run 'make distclean-ext'
to remove old configuration after installing them in such case.
