[ruby-core:111966] [Ruby master Feature#19366] Rename/alias Refinedment#refined_class => #refined_module

Issue #19366 has been reported by zverok (Victor Shepelev). ---------------------------------------- Feature #19366: Rename/alias Refinedment#refined_class => #refined_module https://bugs.ruby-lang.org/issues/19366 * Author: zverok (Victor Shepelev) * Status: Open * Priority: Normal ---------------------------------------- In #12737, `Refinement#refined_class` is introduced. As "module" is more generic concept than "class", the name misleadingly implies that either this method doesn't returns refined _modules_, or modules can't be refined. This is obviously not true and trivially disproved: ```ruby module Refs refine Enumerable do def foo = puts 'foo' end end Refs.refinements[0].refined_class #=> Enumerable. Which is, well, not a class. # The refinement is usable, so it is not a mute concept: using Refs [1, 2, 3].foo # prints "foo" successfully ``` I believe we refer to "modules" when some feature applies to modules and classes. Unless there is some deeper consideration for the current naming (I don't see justification in #12737, but I might miss something), the method should be renamed or aliased. PS: Sorry for a huge amount of "nitpicky" issues after the version release. Typically, those concerns emerge while I am working on the [changelog](https://rubyreferences.github.io/rubychanges/), and I am usually trying to start the work at least a month before the release. Unfortunately, due to you-know-what, I was unable to do it in time this year. After the 3.2 changelog, I plan to switch to the "master changelog" approach (following the development with the "current unreleased changes" document) this year. Unless I'll be unable to due to reasons not in my control. -- https://bugs.ruby-lang.org/

[ruby-core:116589] [Ruby master Misc#20238] Use prism for mk_builtin_loader.rb
by kddnewton (Kevin Newton) 05 Nov '24

Issue #20238 has been reported by kddnewton (Kevin Newton). ---------------------------------------- Misc #20238: Use prism for mk_builtin_loader.rb https://bugs.ruby-lang.org/issues/20238 * Author: kddnewton (Kevin Newton) * Status: Open * Priority: Normal ---------------------------------------- I would like to propose that we use prism for mk_builtin_loader.rb. Right now the Ruby syntax that you can use in builtin classes is restricted to the base Ruby version (2.7). This means you can't use a lot of the nicer syntax that Ruby has shipped in the last couple of years. If we switch to using prism to parse the builtin files instead of using ripper, then we can always use the latest version of Ruby syntax. A pull request for this is here: https://github.com/kddnewton/ruby/pull/65. The approach for the PR is taken from how RJIT bindgen works. -- https://bugs.ruby-lang.org/

Issue #19383 has been reported by stringsn88keys (Thomas Powell). ---------------------------------------- Bug #19383: Time.now.zone encoding for German display language in Windows is incorrect https://bugs.ruby-lang.org/issues/19383 * Author: stringsn88keys (Thomas Powell) * Status: Open * Priority: Normal * ruby -v: 3.1.3 * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- OS: Verified on Windows 10 and Windows Server 2022 and Ruby 2.7.7 through 3.1.3 Display language: Verified on German, but may impact other languages in which Time.now.zone returns characters that aren't [A-Za-z]. Time zone: CET (UTC +01:00) Amsterdam, Berlin, ... Time.now.zone # => "Mitteleuro\xE3ische Zeit" Time.now.zone.encoding # => #<Encoding:IBM437> puts Time.now.zone # => "Mitteleurop∑ische Zeit" (should be "Mitteleuropäische Zeit") Time.now.zone.encode(Encoding::UTF_8) # => "Mitteleurop∑ische Zeit" Doing a force_encoding on all encodings in Encoding.list reveals that ISO-8859-(1..16) and Windows-125(0,2,4,7) work to coerce the ä out of the time zone string: Time.now.zone.force_encoding(Encoding::WINDOWS_1252) # => "Mitteleuro\xE3ische Zeit" ... but ... Time.now.zone.force_encoding(Encoding::WINDOWS_1252).encode(Encoding::UTF_8) #=> "Mitteleuropäische Zeit" Related issue: This improper encoding/rendering caused Ohai's JSON output to be unparseable. Workaround was forcing to Windows-1252. https://github.com/chef/ohai/pull/1781 -- https://bugs.ruby-lang.org/

[ruby-core:116799] [Ruby master Bug#20271] Issue with moving embedded string across ractors
by luke-gru (Luke Gruber) 20 Sep '24

20 Sep '24

Issue #20271 has been reported by luke-gru (Luke Gruber). ---------------------------------------- Bug #20271: Issue with moving embedded string across ractors https://bugs.ruby-lang.org/issues/20271 * Author: luke-gru (Luke Gruber) * Status: Open * Priority: Normal * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- When embedded strings are moved, the embedded bytes aren't copied over to the new embedded string. This shows itself when an embedded string has more than 16 characters, and can also be a problem when the MovedObject has been garbage collected and another object has taken its place in the ruby heap. For example: ```ruby r = Ractor.new { foo = receive puts foo foo } obj = "12345678" * 3 puts obj r.send(obj, move: true) r.take ``` ``` 123456781234567812345678 1234567812345678 ``` -- https://bugs.ruby-lang.org/

Issue #20237 has been reported by hanazuki (Kasumi Hanazuki). ---------------------------------------- Bug #20237: Unable to unshare(CLONE_NEWUSER) in Linux because of timer thread https://bugs.ruby-lang.org/issues/20237 * Author: hanazuki (Kasumi Hanazuki) * Status: Open * Priority: Normal * ruby -v: ruby 3.4.0dev (2024-02-04T16:05:02Z master 8bc6fff322) [x86_64-linux] * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- ## Backgrounds [unshare(2)](https://man7.org/linux/man-pages/man2/unshare.2.html) is a syscall in Linux to move the calling process into a fresh execution context. With `unshare(CLONE_NEWUSER)` you can move a process into a new [user_namespace(7)](https://man7.org/linux/man-pages/man7/user_namespaces.7.…, where the process gains the full capability on the resources within the namespace. This is fundamental for Linux containers to achieve privilege separation. `unshare(CLONE_NEWUSER)` requires the calling process to be single-threaded (or no background threads are running). So, it is often invoked after `fork(2)` as forking propagates only the calling thread to the child process. ## Problem It becomes a problem that Ruby 3.3 on Linux uses timer threads even for a single-`Thread`ed application. Because `Kernel#fork` spawns a thread in the child process before the control returns to the user code, there is no chance to call `unshare(CLONE_NEWUSER)` in Ruby. The following snippet is a reproducer of this problem. This program first forks and then shows the user namespace to which the process belongs before and after calling unshare(2). It also shows the threads of the child process after forking. ```ruby p(RUBY_DESCRIPTION:) require 'fiddle/import' module C extend Fiddle::Importer dlload 'libc.so.6' extern 'int unshare(int flags)' CLONE_NEWUSER = 0x10000000 def self.raise_system_call_error raise SystemCallError.new(Fiddle.last_error) end end pid = fork do system("ps -O tid -T -p #$$") system("ls -l /proc/self/ns/user") if C.unshare(C::CLONE_NEWUSER) != 0 C.raise_system_call_error # => EINVAL with Ruby 3.3 end system("ls -l /proc/self/ns/user") end p Process.wait2(pid) ``` The program successfully changes the user namespace with Ruby 3.2, but it raises EINVAL with Ruby 3.3. You can see Ruby 3.3 has two threads running after forking. ``` % rbenv shell 3.2 && ruby ./test.rb {:RUBY_DESCRIPTION=>"ruby 3.2.3 (2024-01-18 revision 52bb2ac0a6) [x86_64-linux]"} PID TID S TTY TIME COMMAND 1585787 1585787 S pts/12 00:00:00 ruby ./test.rb lrwxrwxrwx 1 kasumi kasumi 0 Feb 5 02:25 /proc/self/ns/user -> 'user:[4026531837]' lrwxrwxrwx 1 nobody nogroup 0 Feb 5 02:25 /proc/self/ns/user -> 'user:[4026532675]' [1585787, #<Process::Status: pid 1585787 exit 0>] % rbenv shell 3.3 && ruby ./test.rb {:RUBY_DESCRIPTION=>"ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [x86_64-linux]"} PID TID S TTY TIME COMMAND 1585849 1585849 S pts/12 00:00:00 ruby ./test.rb 1585849 1585851 S pts/12 00:00:00 ruby ./test.rb lrwxrwxrwx 1 kasumi kasumi 0 Feb 5 02:25 /proc/self/ns/user -> 'user:[4026531837]' ./test.rb:10:in `raise_system_call_error': Invalid argument (Errno::EINVAL) from ./test.rb:24:in `block in <main>' from ./test.rb:19:in `fork' from ./test.rb:19:in `<main>' [1585849, #<Process::Status: pid 1585849 exit 1>] % rbenv shell master && ruby ./test.rb {:RUBY_DESCRIPTION=>"ruby 3.4.0dev (2024-02-04T16:05:02Z master 8bc6fff322) [x86_64-linux]"} PID TID S TTY TIME COMMAND 1585965 1585965 S pts/12 00:00:00 ruby ./test.rb 1585965 1585967 S pts/12 00:00:00 ruby ./test.rb lrwxrwxrwx 1 kasumi kasumi 0 Feb 5 02:25 /proc/self/ns/user -> 'user:[4026531837]' ./test.rb:10:in `raise_system_call_error': Invalid argument (Errno::EINVAL) from ./test.rb:24:in `block in <main>' from ./test.rb:19:in `fork' from ./test.rb:19:in `<main>' [1585965, #<Process::Status: pid 1585965 exit 1>] ``` ## Workaround My workaround is to rebuild ruby with `rb_thread_stop_timer_thread` and `rb_thread_start_timer_thread` exported, and use a C-ext that stops the timer thread before calling `unshare`. This seems not robust because the process cannot know when the terminated thread is reclaimed by the kernel, after which the process is considered single-threaded. ```c #define _GNU_SOURCE 1 #include <sched.h> #include <ruby/ruby.h> static VALUE Unshare_s_unshare(VALUE _self, VALUE rflags) { int const flags = NUM2INT(rflags); rb_thread_stop_timer_thread(); usleep(1000); // FIXME: It takes some time for the kernel to remove the stopped thread? int const ret = unshare(flags); rb_thread_start_timer_thread(); if(ret != 0) rb_sys_fail_str(rb_sprintf("unshare(%#x)", flags)); return Qnil; } RUBY_FUNC_EXPORTED void Init_unshare(void) { VALUE rb_mUnshare = rb_define_module("Unshare"); rb_define_singleton_method(rb_mUnshare, "unshare", Unshare_s_unshare, 1); rb_define_const(rb_mUnshare, "CLONE_NEWUSER", INT2FIX(CLONE_NEWUSER)); } ``` ## Questions - Is this a limitation of Ruby? - Is it safe (or even possible) to stop the timer thread during execution? - If so, can we export it as the public API? - But it may not so useful for this problem as explained in the workaround. - Is it guaranteed that no other threads are running after forks? - Are there any better ways to solve this issue? - Can we somehow delay the start of the timer thread after forking, or hook into `fork` to run some code in the child process immediately after it spawns. - Can they be Ruby API instead of C API? -- https://bugs.ruby-lang.org/

[ruby-core:114645] [Ruby master Bug#19865] Segfault when calling user signal handlers during VM shutdown

Issue #19865 has been reported by ivoanjo (Ivo Anjo). ---------------------------------------- Bug #19865: Segfault when calling user signal handlers during VM shutdown https://bugs.ruby-lang.org/issues/19865 * Author: ivoanjo (Ivo Anjo) * Status: Open * Priority: Normal * ruby -v: ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x86_64-linux] * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- Howdy 👋! I work for Datadog [on the `ddtrace` gem](https://github.com/DataDog/dd-trace-rb) . I've found this issue while investigating a [customer crash report](https://github.com/DataDog/dd-trace-rb/issues/2980). ### Background The original issue was found in a production app. A number of things need to be in play to cause it. The [`ruby-odbc`](https://rubygems.org/gems/ruby-odbc) gem provides a way of accessing databases through the ODBC API. It wraps a database connection as a Data object, with a free function that, prior to freeing the native resources, disconnects from the database if the connection was still active. Because disconnecting from the database is a blocking operation, the gem (reasonably, in my opinion), releases the global VM lock before disconnecting. The trigger for the crash is: 1. The app in question used puma, and puma installs a `Signal.trap('TERM')` 2. The database object was still connected when the app started to shut down 3. A VM shutdown starts... 4. Half-way through shutdown, the VM received a SIGTERM signal, and queued it for processing 5. The VM calls the free function on all objects 6. The ruby-odbc gem sees there's an active database connection, and tries to release the GVL to call the blocking disconnect 7. Before releasing the GVL, the VM checks for pending interruptions 8. The VM tries to run the Ruby-level signal handler method half-way through VM shutdown, when you can no longer run Ruby code 9. Segfault ### How to reproduce (Ruby version & script) I was able to reproduce on a minimal example on Ruby 3.2.2 (`ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x86_64-linux]`) and recent master (`ruby 3.3.0dev (2023-08-17T07:30:01Z master d26b015e83) [x86_64-linux]`). I've put the test-case up on github as well <https://github.com/DataDog/signal-bug-testcase>, but here's the important bits: `signal-bug-testcase.rb`: ```ruby require 'signal_bug_testcase' Signal.trap("TERM") { puts "Hello, world" } FOO = SignalBugTestcase.new ``` `signal_bug_testcase.c`: ```ruby #include <ruby.h> #include <ruby/thread.h> #include <signal.h> #include <unistd.h> typedef struct { int dummy; } BugTestcase; void *test_nogvl(void *unused) { fprintf(stderr, "GVL released!\n"); return NULL; } static void bug_testcase_free(void* ptr) { fprintf(stderr, "Free getting called! Sending signal...\n"); kill(getpid(), SIGTERM); fprintf(stderr, "SIGTERM signal queued, trying to release GVL...\n"); rb_thread_call_without_gvl(test_nogvl, NULL, NULL, NULL); fprintf(stderr, "After releasing GVL!\n"); free(ptr); } const rb_data_type_t bug_testcase_data_type = { .wrap_struct_name = "SignalBugTestcase", .function = { NULL, bug_testcase_free, NULL }, .flags = RUBY_TYPED_FREE_IMMEDIATELY }; VALUE bug_testcase_alloc(VALUE klass) { BugTestcase* obj = calloc(1, sizeof(BugTestcase)); return TypedData_Make_Struct(klass, BugTestcase, &bug_testcase_data_type, obj); } void Init_signal_bug_testcase(void) { VALUE cBugTestcase = rb_define_class("SignalBugTestcase", rb_cObject); rb_define_alloc_func(cBugTestcase, bug_testcase_alloc); } ``` ### Expectation and result No segfault happens. Interestingly, on Ruby 2.7, the VM exits half-way through but doesn't always segfault, but running it a few times always triggers the issue. On 3.2+ it crashes every time for me. I suspect the right thing here is to no longer accept/try to run any Ruby-level signal handlers after VM shutdown starts. Here's what I see with this test-case: ``` $ bundle exec ruby lib/signal-bug-testcase.rb Free getting called! Sending signal... SIGTERM signal queued, trying to release GVL... lib/signal-bug-testcase.rb:3: [BUG] Segmentation fault at 0x0000000000000007 ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x86_64-linux] -- Control frame
