E.g. * Are the Bundled gems considered a part of StdLib or not? * What is general strategy for the future, seeing more and more gems moving from default to bundled gems in Ruby 3.1 * Default gems does not need to be listed in Gemfile where Bundled gems needs to be listed in Gemfile * Default gems can be used without RubyGems where Bundled gems requires RubyGems -- https://bugs.ruby-lang.org/

[ruby-core:114550] [Ruby master Bug#18080] Syntax error on one-line pattern matching
by mdalessio (Mike Dalessio) 25 Aug '23

25 Aug '23

Issue #18080 has been updated by mdalessio (Mike Dalessio). Looks like YARP already supports this. ``` "> YARP.parse <<~EOF "> p 1 do "> end => a >> EOF => #<YARP::ParseResult:0x00007f0f326c9100 @comments=[], @errors=[], @source=#<YARP::Source:0x00007f0f3289cab8 @offsets=[0, 7, 16], @source="p 1 do\nend => a\n">, @value= ProgramNode(0...15)( [:a], StatementsNode(0...15)( [MatchRequiredNode(0...15)( CallNode(0...10)( nil, nil, (0...1), nil, ArgumentsNode(2...3)([IntegerNode(2...3)()]), nil, BlockNode(4...10)([], nil, nil, (4...6), (7...10)), 0, "p" ), LocalVariableWriteNode(14...15)(:a, 0, nil, (14...15), nil), (11...13) )] ) ), @warnings=[]> ``` ---------------------------------------- Bug #18080: Syntax error on one-line pattern matching https://bugs.ruby-lang.org/issues/18080#change-104355 * Author: ko1 (Koichi Sasada) * Status: Open * Priority: Normal * ruby -v: 3.1.0dev * Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN ---------------------------------------- One line pattern matching with a method return value with parameters which are not surrounded by parenthesis raises syntax error. I think it is not intentional, but nobu said it's hard to support because of parse.y limitation. ```ruby p do end => a p a #=> nil p(1) do end => a p a #=> 1 p 1 do end => a #=> # syntax error, unexpected =>, expecting end-of-input # end => a # ^~ p 1 do end in a #=> # syntax error, unexpected `in', expecting end-of-input # end in a # ^~ ``` -- https://bugs.ruby-lang.org/

[ruby-core:114548] [Ruby master Bug#18144] Timeout not working while regular expression match is running
by jeremyevans0 (Jeremy Evans) 25 Aug '23

25 Aug '23

Issue #18144 has been updated by jeremyevans0 (Jeremy Evans). Status changed from Open to Closed This issue appears fixed in Ruby 3.2, due to regexp optimizations by @makenowjust. If there are regexps that are still experiencing this issue, please report them and we can reopen. ---------------------------------------- Bug #18144: Timeout not working while regular expression match is running https://bugs.ruby-lang.org/issues/18144#change-104350 * Author: duerst (Martin Dürst) * Status: Closed * Priority: Normal * ruby -v: various, see description * Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN ---------------------------------------- Experimenting with dozens of regular expressions that take a long time to match against certain strings, I have found that for some regular expression matches, Timeouts don't work at all (while they work for the rest without problems). The attached file allows reproduction. On three different machines and with six different versions of Ruby (see below), the attached file always showed about 20~25 seconds of execution time even though there was a Timeout interval of only 10s. If your machine is too fast so that the printed-out result comes in below or just a bit above 10s, then either lower the timeout duration (e.g. to 5s) or increase the length of the string (e.g. 80_000 -> 100_000; caution, time increases with the second power of this number). The timeout uses `Timeout::timeout` and `rescue Timeout::Error` as described in the pickaxe. Checked with the following versions/environments: - ruby 3.1.0dev (2021-06-03T06:59:33Z master 7e14762159) [x86_64-linux] on Ubuntu on WSL on a Windows 10 notebook - ruby 2.6.4p104 (2019-08-28 revision 67798) [x86_64-cygwin] on same notebook - ruby 3.0.0p0 (2020-12-25 revision 95aff21468) [x64-mingw32] on same notebook - ruby 3.1.0dev (2021-06-03T06:59:33Z master 7e14762159) [x86_64-linux] on Ubuntu on WSL on same notebook - ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-linux-gnu] on a two-CPU Dell server with Ubuntu - ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux] on an older Dell server with CentOS ---Files-------------------------------- no_timeout.rb (333 Bytes) -- https://bugs.ruby-lang.org/

[ruby-core:114546] [Ruby master Bug#18080] Syntax error on one-line pattern matching
by jeremyevans0 (Jeremy Evans) 25 Aug '23

25 Aug '23

Issue #18080 has been updated by jeremyevans0 (Jeremy Evans). @kddnewton Is this possible to support in YARP? @yui-knk Is this possible to support in parse.y/lrama? ---------------------------------------- Bug #18080: Syntax error on one-line pattern matching https://bugs.ruby-lang.org/issues/18080#change-104348 * Author: ko1 (Koichi Sasada) * Status: Open * Priority: Normal * ruby -v: 3.1.0dev * Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN ---------------------------------------- One line pattern matching with a method return value with parameters which are not surrounded by parenthesis raises syntax error. I think it is not intentional, but nobu said it's hard to support because of parse.y limitation. ```ruby p do end => a p a #=> nil p(1) do end => a p a #=> 1 p 1 do end => a #=> # syntax error, unexpected =>, expecting end-of-input # end => a # ^~ p 1 do end in a #=> # syntax error, unexpected `in', expecting end-of-input # end in a # ^~ ``` -- https://bugs.ruby-lang.org/

[ruby-core:114543] [Ruby master Bug#17678] Ractors do not restart after fork
by jeremyevans0 (Jeremy Evans) 25 Aug '23

25 Aug '23

Issue #17678 has been updated by jeremyevans0 (Jeremy Evans). I updated https://github.com/ruby/ruby/pull/8283 to mark non-main ractors as terminated after fork. ---------------------------------------- Bug #17678: Ractors do not restart after fork https://bugs.ruby-lang.org/issues/17678#change-104345 * Author: ivoanjo (Ivo Anjo) * Status: Assigned * Priority: Normal * Assignee: ko1 (Koichi Sasada) * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- Hello there! I'm working at Datadog on the `ddtrace` gem -- <https://github.com/DataDog/dd-trace-rb> and we're experimenting with using Ractors in our library but run into a few issues. ### Background When running a Ractor as a background process, the Ractor stops & does not restart when the application forks. ### How to reproduce (Ruby version & script) `ruby 3.0.0p0 (2020-12-25 revision 95aff21468) [x86_64-linux]` ```ruby r2 = Ractor.new do loop { puts "[#{Process.pid}] Ractor"; sleep(1) } end sleep(1) puts "[#{Process.pid}] Forking..." fork do sleep(5) puts "[#{Process.pid}] End fork." end loop do sleep(1) end ``` ### Expectation and result The application prints “Ractor” each second in the main process, but not in the fork. Expected the Ractor (defined as `r2`) to run in the fork. ``` [29] Ractor [29] Ractor [29] Forking... [29] Ractor [29] Ractor [29] Ractor [29] Ractor [29] Ractor [32] End fork. [29] Ractor [29] Ractor [29] Ractor ``` ### Additional notes Threads do not restart across forks either, so it might not be unreasonable to expect consistent behavior. However, it’s possible to detect a dead Thread and recreate it after a fork (e.g. with `#alive?`, `#status`), but there’s no such mechanism for Ractors. ### Suggested solutions 1. Auto-restart Ractors after fork 2. Add additional methods to Ractors that allow users to check & manage the status of the Ractor, similar to Thread. -- https://bugs.ruby-lang.org/
