[ruby-talk:444386] Ruby 3.3.0 Released

by NARUSE, Yui

We are pleased to announce the release of Ruby 3.3.0. Ruby 3.3 adds a new parser named Prism, uses Lrama as a parser generator, adds a new pure-Ruby JIT compiler named RJIT, and many performance improvements especially YJIT. ## Prism * Introduced [the Prism parser](https://github.com/ruby/prism) as a default gem * Prism is a portable, error tolerant, and maintainable recursive descent parser for the Ruby language * Prism is production ready and actively maintained, you can use it in place of Ripper * There is [extensive documentation](https://ruby.github.io/prism/) on how to use Prism * Prism is both a C library that will be used internally by CRuby and a Ruby gem that can be used by any tooling which needs to parse Ruby code * Notable methods in the Prism API are: * `Prism.parse(source)` which returns the AST as part of a parse result object * `Prism.parse_comments(source)` which returns the comments * `Prism.parse_success?(source)` which returns true if there are no errors * You can make pull requests or issues directly on [the Prism repository](https://github.com/ruby/prism) if you are interested in contributing * You can now use `ruby --parser=prism` or `RUBYOPT="--parser=prism"` to experiment with the Prism compiler. Please note that this flag is for debugging only. ## Use Lrama instead of Bison * Replace Bison with [Lrama LALR parser generator](https://github.com/ruby/lrama) [[Feature #19637]](https://bugs.ruby-lang.org/issues/19637) * If you have interest, please see [The future vision of Ruby Parser](https://rubykaigi.org/2023/presentations/spikeolaf.html) * Lrama internal parser is replaced with LR parser generated by Racc for maintainability * Parameterizing Rules `(?, *, +)` are supported, it will be used in Ruby parse.y ## YJIT * Major performance improvements over Ruby 3.2 * Support for splat and rest arguments has been improved. * Registers are allocated for stack operations of the virtual machine. * More calls with optional arguments are compiled. Exception handlers are also compiled. * Unsupported call types and megamorphic call sites no longer exit to the interpreter. * Basic methods like Rails `#blank?` and [specialized `#present?`](https://github.com/rails/rails/pull/49909) are inlined. * `Integer#*`, `Integer#!=`, `String#!=`, `String#getbyte`, `Kernel#block_given?`, `Kernel#is_a?`, `Kernel#instance_of?`, and `Module#===` are specially optimized. * Compilation speed is now slightly faster than Ruby 3.2. * Now more than 3x faster than the interpreter on Optcarrot! * Significantly improved memory usage over Ruby 3.2 * Metadata for compiled code uses a lot less memory. * `--yjit-call-threshold` is automatically raised from 30 to 120 when the application has more than 40,000 ISEQs. * `--yjit-cold-threshold` is added to skip compiling cold ISEQs. * More compact code is generated on Arm64. * Code GC is now disabled by default * `--yjit-exec-mem-size` is treated as a hard limit where compilation of new code stops. * No sudden drops in performance due to code GC. Better copy-on-write behavior on servers reforking with [Pitchfork](https://github.com/shopify/pitchfork). * You can still enable code GC if desired with `--yjit-code-gc` * Add `RubyVM::YJIT.enable` that can enable YJIT at run-time * You can start YJIT without modifying command-line arguments or environment variables. Rails 7.2 will [enable YJIT by default](https://github.com/rails/rails/pull/49947) using this method. * This can also be used to enable YJIT only once your application is done booting. `--yjit-disable` can be used if you want to use other YJIT options while disabling YJIT at boot. * More YJIT stats are available by default * `yjit_alloc_size` and several more metadata-related stats are now available by default. * `ratio_in_yjit` stat produced by `--yjit-stats` is now available in release builds, a special stats or dev build is no longer required to access most stats. * Add more profiling capabilities * `--yjit-perf` is added to facilitate profiling with Linux perf. * `--yjit-trace-exits` now supports sampling with `--yjit-trace-exits-sample-rate=N` * More thorough testing and multiple bug fixes ## RJIT * Introduced a pure-Ruby JIT compiler RJIT and replaced MJIT. * RJIT supports only x86-64 architecture on Unix platforms. * Unlike MJIT, it doesn't require a C compiler at runtime. * RJIT exists only for experimental purposes. * You should keep using YJIT in production. * If you are interested in developing JIT for Ruby, please check out [k0kubun's presentation on Day 3 of RubyKaigi](https://rubykaigi.org/2023/presentations/k0kubun.html#day3). ## M:N thread scheduler * M:N thread scheduler was introduced. [[Feature #19842]](https://bugs.ruby-lang.org/issues/19842) * M Ruby threads are managed by N native threads (OS threads) so the thread creation and management cost are reduced. * It can break C-extension compatibility so that M:N thread scheduler is disabled on the main Ractor by default. * `RUBY_MN_THREADS=1` environment variable enables M:N threads on the main Ractor. * M:N threads are always enabled on non-main Ractors. * `RUBY_MAX_CPU=n` environment variable sets maximum number of `N` (maximum number of native threads). The default value is 8. * Since only one Ruby thread per Ractor can run at the same time, the number of native threads will be used, which is the smaller of the number specified in `RUBY_MAX_CPU` and the number of running Ractors. So that single Ractor applications (most of applications) will only use 1 native thread. * To support blocking operations, more than `N` native threads can be used. ## Performance improvements * `defined?(@ivar)` is optimized with Object Shapes. * Name resolution such as `Socket.getaddrinfo` can now be interrupted (in environments where pthreads are available). [[Feature #19965]](https://bugs.ruby-lang.org/issues/19965) * Several performance improvements to the Garbage Collector * Young objects referenced by old objects are no longer immediately promoted to the old generation. This significantly reduces the frequency of major GC collections. [[Feature #19678]](https://bugs.ruby-lang.org/issues/19678) * A new `REMEMBERED_WB_UNPROTECTED_OBJECTS_LIMIT_RATIO` tuning variable was introduced to control the number of unprotected objects cause a major GC collection to trigger. The default is set to `0.01` (1%). This significantly reduces the frequency of major GC collection. [[Feature #19571]](https://bugs.ruby-lang.org/issues/19571) * Write Barriers were implemented for many core types that were missing them, notably `Time`, `Enumerator`, `MatchData`, `Method`, `File::Stat`, `BigDecimal` and several others. This significantly reduces minor GC collection time and major GC collection frequency. * Most core classes are now using Variable Width Allocation, notably `Hash`, `Time`, `Thread::Backtrace`, `Thread::Backtrace::Location`, `File::Stat`, `Method`. This makes these classes faster to allocate and free, use less memory and reduce heap fragmentation. * Support for weak references has been added to the garbage collector. [[Feature #19783]](https://bugs.ruby-lang.org/issues/19783) ## Other notable changes since 3.2 ### IRB IRB has received several enhancements, including but not limited to: - Advanced `irb:rdbg` integration that provides an equivalent debugging experience to `pry-byebug` ([doc](https://github.com/ruby/irb#debugging-with-irb)). - Pager support for `ls`, `show_source` and `show_cmds` commands. - More accurate and helpful information provided by the `ls` and `show_source` commands. - Experimental autocompletion using type analysis ([doc](https://github.com/ruby/irb#type-based-completion)). - It is now possible to change the font color and font style in the completion dialog by a newly introduced class Reline::Face ([doc](https://github.com/ruby/ruby/blob/master/doc/reline/face.md)) In addition, IRB has also undergone extensive refactoring and received dozens of bug fixes to facilitate easier future enhancements. ## Compatibility issues Note: Excluding feature bug fixes. * `it` calls without arguments in a block with no ordinary parameters are deprecated. `it` will be a reference to the first block parameter in Ruby 3.4. [[Feature #18980]](https://bugs.ruby-lang.org/issues/18980) ### Removed environment variables The following deprecated methods are removed. * Environment variable `RUBY_GC_HEAP_INIT_SLOTS` has been deprecated and is a no-op. Please use environment variables `RUBY_GC_HEAP_{0,1,2,3,4}_INIT_SLOTS` instead. [[Feature #19785]](https://bugs.ruby-lang.org/issues/19785) ## Stdlib compatibility issues ### `ext/readline` is retired * We have `reline` that is pure Ruby implementation compatible with `ext/readline` API. We rely on `reline` in the future. If you need to use `ext/readline`, you can install `ext/readline` via rubygems.org with `gem install readline-ext`. * We no longer need to install libraries like `libreadline` or `libedit`. ## Standard library updates RubyGems and Bundler warn if users do `require` the following gems without adding them to Gemfile or gemspec. This is because they will become the bundled gems in the future version of Ruby. This warning is suppressed if you use bootsnap gem. We recoomend to run your application with `DISABLE_BOOTSNAP=1` environmental variable at least once. This is limitation of this version.

[ruby-talk:444383] [ANN] httpx 1.2.0 released

by Tiago Cardoso

httpx 1.2.0 has been released. ``` HTTPX.get("https://gitlab.com/honeyryderchuck/httpx <https://gitlab.com/honeyryderchuck/httpx>") ``` HTTPX is an HTTP client library for the Ruby programming language. Among its features, it supports: * HTTP/2 and HTTP/1.x protocol versions * Concurrent requests by default * Simple and chainable API * Proxy Support (HTTP(S), CONNECT tunnel, Socks4/4a/5) * Simple Timeout System * Lightweight by default (require what you need) And also: * Compression (gzip, deflate, brotli) * Streaming Requests * Authentication (Basic Auth, Digest Auth, AWS Sigv4) * Expect 100-continue * Multipart Requests * Cookies * HTTP/2 Server Push * H2C Upgrade * Automatic follow redirects * International Domain Names * GRPC * Circuit breaker * WebDAV * SSRF Filter * Datadog integration * Faraday integration * Webmock integration * Sentry integration Here are the updates since the last release: # 1.2.0 ## Features ### `:ssrf_filter` plugin The `:ssrf_filter` plugin prevents server-side request forgery attacks, by blocking requests to the internal network. This is useful when the URLs used to perform requests aren’t under the developer control (such as when they are inserted via a web application form). ```ruby http = HTTPX.plugin(:ssrf_filter) # this works response = http.get("https://example.com") # this doesn't response = http.get("http://localhost:3002") response = http.get("http://[::1]:3002") response = http.get("http://169.254.169.254/latest/meta-data/") ``` More info under https://honeyryderchuck.gitlab.io/httpx/wiki/SSRF-Filter ### `:callbacks` plugin The session callbacks introduced in v0.24.0 are in its own plugin. Older code will still work and emit a deprecation warning. More info under https://honeyryderchuck.gitlab.io/httpx/wiki/Callbacks ### `:redirect_on` option for `:follow_redirects` plugin This option allows passing a callback which, when returning `false`, can interrupt the redirect loop. ```ruby http = HTTPX.plugin(:follow_redirects).with(redirect_on: ->(location_uri) { BLACKLIST_HOSTS.include?(location_uri.host) ] ``` ### `:close_on_handshake_timeout` timeout A new `:timeout` option, `:close_handshake_timeout`, is added, which monitors connection readiness when performing HTTP/2 connection termination handshake. ## Improvements * Internal "eden connections" concept was removed, and connection objects are now kept-and-reused during the lifetime of a session, even when closed. This simplified connectio pool implementation and improved performance. * request using `:proxy` and `:retries` plugin enabled sessions will now retry on proxy connection establishment related errors. ## Bugfixes * webmock adapter: mocked responses storing decoded payloads won't try to decode them again (fixes vcr/webmock integrations). * webmock adapter: fix issue related with making real requests over webmock-enabled connection. # 1.1.5 ## improvements * pattern matching support for responses has been backported to ruby 2.7 as well. ## bugfixes * `stream` plugin: fix for `HTTPX::StreamResponse#each_line` not yielding the last line of the payload when not delimiter-terminated. * `stream` plugin: fix `webmock` adapter integration when methods calls would happen in the `HTTPX::StreamResponse#each` block. * `stream` plugin: fix `:follow_redirects` plugin integration which was caching the redirect response and using it for method calls inside the `HTTPX::StreamResponse#each` block. * "103 early hints" responses will be ignored when processing the response (it was causing the response returned by sesssions to hold its headers, instead of the following 200 response, while keeping the 200 response body). # 1.1.4 ## bugfixes * datadog adapter: use `Gem::Version` to invoke the correct configuration API. * stream plugin: do not preempt request enqueuing (this was making integration with the `:follow_redirects` plugin fail when set up with `webmock`). # 1.1.3 ## improvements ## security * when using `:follow_redirects` plugin, the "authorization" header will be removed when following redirect responses to a different origin. ## bugfixes * fixed `:stream` plugin not following redirect responses when used with the `:follow_redirects` plugin. * fixed `:stream` plugin not doing content decoding when responses were p.ex. gzip-compressed. * fixed bug preventing usage of IPv6 loopback or link-local addresses in the request URL in systems with no IPv6 internet connectivity (the request was left hanging). * protect all code which may initiate a new connection from abrupt errors (such as internet turned off), as it was done on the initial request call. ## chore internal usage of `mutex_m` has been removed (`mutex_m` is going to be deprecated in ruby 3.3). # 1.1.2 ## improvements * only moving eden connections to idle when they're recycled. ## bugfixes * skip closing a connection which is already closed during reset. * sentry adapter: fixed `super` call which didn't have a super method (this prevented usinng sentry-enabled sessions with the `:retries` plugin). * sentry adapter: fixing registering of sentry config. * sentry adapter: do not propagate traces when relevant sdk options are disabled (such as `propagate_traces`). # 1.1.1 ## improvements * (Re-)enabling default retries in DNS name queries; this had been disabled as a result of revamping timeouts, and resulted in queries only being sent once, which is very little for UDP-related traffic, and breaks if using DNs rate-limiting software. Retries the query just once, for now. ## bugfixes * reset timers when adding new intervals, as these may be added as a result on after-select connection handling, and must wait for the next tick cycle (before the patch, they were triggering too soon). * fixed "on close" callback leak on connection reuse, which caused linear performance regression in benchmarks performing one request per connection. * fixed hanging connection when an HTTP/1.1 emitted a "connection: close" header but the server would not emit one (it closes the connection now). * fixed recursive dns cached lookups which may have already expired, and created nil entries in the returned address list. * dns system resolver is now able to retry on failure. ## chore * remove duplicated callback unregistering connections.
