JRuby - 一个Ruby语言的Java实现

The JRuby community is pleased to announce the release of JRuby 9.2.11.1

• Homepage: http://www.jruby.org/
• Download: http://www.jruby.org/download

JRuby 9.2.x is compatible with Ruby 2.5.x and stays in sync with C Ruby. As always there is a mix of miscellaneous fixes so be sure to read the issue list below. All users are encouraged to upgrade.

As we are actively working on 9.3.0.0 we decided to put out a mini release which fixes a single issue.

• sprintf substring string formatting with precision may expose characters (#6137)

If you format a string using a precision specifier (e.g. %.1s) AND you pass in a substring of a larger string, you may see some of the larger string's characters in the formatted result. This is due to a bug in the handling of internal String data that causes the result to contain more characters than requested.

long_string = "aabbccddhelloddccbbaa"
start_index = 8
sub_str_length = 5
precision = 3
sub_string = long_string[start_index, sub_str_length]
puts sprintf("%.#{precision}s", sub_string)
# => helloddccbb

This bug could potentially expose sensitive content from the original String. It is unlikely to affect most users, but you are still encouraged to upgrade.

Github Issues resolved for 9.2.11.1

• #6138 - Subtract begin offset for partial substring in sprintf 's'
• #6137 - `sprintf` adds extra buffer slots when precision arg truncates string slices

Java Integration

• Gems and gem paths packaged inside jar files will properly load now. This 9.2.10.0 regression was caused by a change in RubyGems 3 that exposed a bug in JRuby. (#6060, #6082, #6083, #6084)

Performance Improvements

• Fixed a major performance and memory bottleneck in backtrace generation, used by Kernel#caller and friends. This was a regression in 9.2.10.0. (#6089)

Github Issues resolved for 9.2.11.0

• #6097 - CGI.escapeHTML restore the original encoding
• #6093 - CGI.escapeHTML crashes on invalid byte sequence where CRuby does not
• #6091 - Check arity earlier in JavaConstructor#new_instance
• #6090 - [9.2.10.0] bogus revision regression
• #6089 - Pontential performance issue
• #6084 - Use expand_path logic for Dir.glob base path
• #6083 - Basic smoke test with warbler no longer works with jruby-jars-9.2.10
• #6082 - Upgrade to 9.2.10.0 breaks project using asciidoctor-maven-plugin
• #6081 - Dependency convergence errors in 9.2.10.0
• #6079 - newInstance on protected/private classes sometimes give an Index OOB Exception
• #6060 - Globbed jar contents with expand path failing in RubyGems

Ruby Core

• Kernel#send and BasicObject#__send__ will now honor refinements used in the surrounding scopes. (#5945, #6045)
• Kernel#eval will now honor refinements used in a given binding. (#6017)
• Process#spawn now correctly processes environment variables for the child process. (#3428, #5907)

Ruby Standard Library

• RubyGems has been updated to version 3.0.6. (#5995, #5996)
• The jruby-openssl library has been updated to 0.10.4. This release improves support for newer forms of ciphers and cryptographic keys and reduces the number of Java module warnings displayed. (#6077)
• The compatibility of the fiddle library has been improved. (#5955, #5956, #5960)

Java Support

• Java methods looked up one-at-a-time using java_method and friends now honor Java modules. This fixes some
  illegal access errors introduced in JRuby 9.2.9.0. (#5894, #5969, #6043, #6069, #6072)
• More illegal access warnings have been cleaned up in JRuby and the jruby-openssl extension.

Native FFI Improvements

• The native subsystem has been rebuilt on MacOS to avoid security warnings due to the old toolchain originally used to build it. (#6044, #6074)
• Native constants have been updated for Windows to better support the Ruby socket API. (#5656, #6070, #6071)

Performance Improvements

• Several improvements to the method invocation pipeline and JVM bytecode output to improve JIT optimizations. (#5958, #5959, #5978, #5992, #6005)
• Several core methods used by Rails and the internal handling of exception backtraces have been optimized. (#5952, #5961, #5965, #5972, #6014, #6015, #6031, #6067)

JRuby Launcher

• Java options dotfiles accidentally omitted in the JRuby 9.2.9.0 release have been restored in the bin directory.
• The bash-based launcher script has been cleaned up and optimized for cross-platform compatibility. (#5977, #6007, #6016)
