[ruby-core:111953] [Ruby master Bug#19362] #dup on Proc doesn't call initialize_dup
by zverok (Victor Shepelev) 25 Oct '23

Issue #19362 has been reported by zverok (Victor Shepelev). ---------------------------------------- Bug #19362: #dup on Proc doesn't call initialize_dup https://bugs.ruby-lang.org/issues/19362 * Author: zverok (Victor Shepelev) * Status: Open * Priority: Normal * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- In #17545, `#dup` had changed to create an instance of the subclass. It, though, doesn't invoke `initialize_dup` of the subclass, unlike other standard classes. ```ruby class MyAry < Array def initialize_dup(...) p(self.class, ...) super end end class MyString < String def initialize_dup(...) p(self.class, ...) super end end class MyProc < Proc def initialize_dup(...) p(self.class, ...) super end end MyString.new('test').dup # prints MyString, "test" MyAry.new(['test']).dup # prints MyAry, ["test"] MyProc.new { 'test' }.dup # doesn't print anything ``` This makes the change in #17545 useless: while inheriting from core classes is indeed marginal, one of author's intention might be carrying additional information with the Proc instance, and bypassing `#initialize_dup` makes it impossible to maintain this information. It seems that actually `#initialize_dup` is also invoked on the core classes themselves, but ignored on `Proc`. ```ruby class Array def initialize_dup(...) p(self.class, ...) super end end class String def initialize_dup(...) p(self.class, ...) super end end class Proc def initialize_dup(...) p(self.class, ...) super end end 'test'.dup # prints String, "test" ['test'].dup # prints Array, ["test"] Proc.new { 'test' }.dup # doesn't print anything ``` Which is an even more marginal problem but still an inconsistency. -- https://bugs.ruby-lang.org/

Issue #19828 has been reported by postmodern (Hal Brodigan). ---------------------------------------- Bug #19828: Segfault when `OpenSSL::X509::Certificate#public_key=` is given a `OpenSS::PKey::DH` object https://bugs.ruby-lang.org/issues/19828 * Author: postmodern (Hal Brodigan) * Status: Open * Priority: Normal * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- The OpenSSL bindings cause a SegFault when creating a new OpenSSL::X509::Certificate object and setting it's `public_key` to the `public_key` of a new `OpenSSL::PKey::DH` key-pair. ### Steps To Reproduce ```ruby #!/usr/bin/env ruby require 'openssl' cert = OpenSSL::X509::Certificate.new key = OpenSSL::PKey::DH.generate(1024) cert.public_key = key.public_key ``` ### Expected Results Sets the public key. ### Actual Results ``` test.rb:8: [BUG] Segmentation fault at 0x0000000000000010 ruby 3.3.0dev (2023-08-02T18:35:08Z master 32e828bb4a)

[ruby-core:112944] [Ruby master Feature#19541] Proposal: Generate frame unwinding info for YJIT code
by kjtsanaktsidis (KJ Tsanaktsidis) 19 Oct '23

19 Oct '23

Issue #19541 has been reported by kjtsanaktsidis (KJ Tsanaktsidis). ---------------------------------------- Feature #19541: Proposal: Generate frame unwinding info for YJIT code https://bugs.ruby-lang.org/issues/19541 * Author: kjtsanaktsidis (KJ Tsanaktsidis) * Status: Open * Priority: Normal ---------------------------------------- ## What is being propsed? Currently, Ruby crashes with yjit generated code on the stack, `rb_print_backtrace()` is unable to actually show any frames underneath the yjit code. For example, if you send SIGSEGV to a Ruby process running yjit, this is what you see: ``` /ruby/miniruby(rb_print_backtrace+0xc) [0xaaaad0276884] /ruby/vm_dump.c:785 /ruby/miniruby(rb_vm_bugreport) /ruby/vm_dump.c:1093 /ruby/miniruby(rb_bug_for_fatal_signal+0xd0) [0xaaaad0075580] /ruby/error.c:813 /ruby/miniruby(sigsegv+0x5c) [0xaaaad01bedac] /ruby/signal.c:919 linux-vdso.so.1(__kernel_rt_sigreturn+0x0) [0xffff91a3e8bc] /ruby/miniruby(map<(usize, yjit::backend::ir::Insn), (usize, yjit::backend::ir::Insn), yjit::backend::ir::{impl#17}::next_mapped::{closure_env#0}>+0x8c) [0xaaaad03b8b00] /rustc/897e37553bba8b42751c67658967889d11ecd120/library/core/src/option.rs:929 /ruby/miniruby(next_mapped+0x3c) [0xaaaad0291dc0] src/backend/ir.rs:1225 /ruby/miniruby(arm64_split+0x114) [0xaaaad0287744] src/backend/arm64/mod.rs:359 /ruby/miniruby(compile_with_regs+0x80) [0xaaaad028bf84] src/backend/arm64/mod.rs:1106 /ruby/miniruby(compile+0xc4) [0xaaaad0291ae0] src/backend/ir.rs:1158 /ruby/miniruby(gen_single_block+0xe44) [0xaaaad02b1f88] src/codegen.rs:854 /ruby/miniruby(gen_block_series_body+0x9c) [0xaaaad03b0250] src/core.rs:1698 /ruby/miniruby(gen_block_series+0x50) [0xaaaad03b0100] src/core.rs:1676 /ruby/miniruby(branch_stub_hit_body+0x80c) [0xaaaad03b1f68] src/core.rs:2021 /ruby/miniruby({closure#0}+0x28) [0xaaaad02eb86c] src/core.rs:1924 /ruby/miniruby(do_call<yjit::core::branch_stub_hit::{closure_env#0}, *const u8>+0x98) [0xaaaad035ba3c] /rustc/897e37553bba8b42751c67658967889d11ecd120/library/std/src/panicking.rs:492 [0xaaaad035c9b4] ``` (n.b. - I compiled Ruby with `-fasynchronous-unwind-tables –rdynamic –g` in cflags to make sure gcc generates appropriate unwind info & keeps the symbol tables). Likewise, if you attach gdb to a Ruby process with yjit enabled, gdb can't show thread backtraces through yjit-generated code either. My proposal is that YJIT generate sufficient unwinding and debug information on all platforms to allow both `rb_print_backtrace()` and the platform's debugger (gdb/lldb/WinDbg) to show: * Full stack traces all the way back to `main`. That is, it should be possible to see frames _underneath_ `[0xaaaad035c9b4]` from the backtrace above. * Names for the dynamically generated yjit blocks (e.g. instead of `[0xaaaad035c9b4]`, we should see something like `yjit$$name_of_ruby_method`, where `name_of_ruby_method` is the `label` for the iseq this is JIT'd code for). ## Motivation I have a few motivations for wanting this. Firstly, I feel this functionality is independently useful. When Ruby crashes, the more information we can get, the more likely we are to find the root cause. Likewise, the same principle applies to debugging with gdb - you can get a fuller understanding of what the process is doing if you see the whole stack. I have often found attaching gdb to the Ruby interpreter helps in understanding problems in Ruby code or C extensions and is something I do relatively frequently; yjit breaking that will definitely be inconvenient for me! ## Implementation I have a draft implementation here on how I'd implement this: . It's currently missing tests & platform support (it only works on Linux aarch64). Also, it implements unwind info generation, so unwinding can work _through_ yjit code, but it does not currently emit symbols to give _names_ to those yjit frames. My PR contains a document which explains how the Linux interfaces for registering unwind info for JIT'd code work, so I won't duplicate that information here. The biggest implementation question I had is around the use of Rust crates. Currently, I prototyped my implementation using the gimli & object crates, for generating DWARF info and ELF binaries. However, the yjit build does purposefully does not use cargo & external crates for release builds. There are a few different ways we could go here: * Don't use the gimli & object crates; instead, re-implement all debug info & object file generation code in yjit. * Don't use the crates; instead, link againt C libraries to provide this functionality & call them from Rust (perhaps some combination of libelf, libdw, libbfd, or llvm might do what we need) * Use cargo after all for the release build & download the crates at build-time * Use cargo for the release build, but vendor everything, so the build doesn't need to download anything * Only make unwind info generation available in dev mode where cargo is used, and so mark the gimli/object dependencies as optional in Cargo.toml. We'd need to decide on one of these approaches for this proposal to work. I don't really have a strong sense of the pros/cons of each. (Side note - my PR actually depends on a _fork_ of gimli - I've been discussing adding the needed interfaces upstream here: https://github.com/gimli-rs/gimli/issues/648) ## Benchmarks I ran the yit-bench suite on my branch and compared it to Ruby master: * My branch: https://gist.github.com/KJTsanaktsidis/5741a9f64e5cd75cdf5fedd846091a4f * Ruby master: https://gist.github.com/KJTsanaktsidis/592d3ebcf98f6745dfa3efbd30a25acf This is a (very simple) comparison: ``` -------------- ------------ ------------ --------------- bench yjit (ms) branch (ms) branch/yjit (%) activerecord 97.5 98.5 101.03% hexapdf 2415.3 2458.2 101.78% liquid-c 61.9 63.1 101.94% liquid-render 135.3 135.0 99.78% mail 104.6 105.5 100.86% psych-load 1887.1 1922.0 101.85% railsbench 1544.4 1556.0 100.75% ruby-lsp 88.4 89.5 101.24% sequel 147.5 151.1 102.44% binarytrees 303 305.6 100.86% chunky_png 1075.8 1079.4 100.33% erubi 392.9 392.3 99.85% erubi_rails 14.7 14.7 100.00% etanni 792.3 791.4 99.89% fannkuchredux 3815.9 3813.6 99.94% lee 1030.2 1039.2 100.87% nbody 49.2 49.3 100.20% optcarrot 4142 4143.3 100.03% ruby-json 2860.7 2874.0 100.46% rubykon 7906.6 7904.2 99.97% 30k_ifelse 348.7 345.4 99.05% 30k_methods 828.6 831.8 100.39% cfunc_itself 28.8 28.9 100.35% fib 34.4 34.5 100.29% getivar 115.5 109.7 94.98% keyword_args 37.7 38.0 100.80% respond_to 26 26.1 100.38% setivar 33.8 33.5 99.11% setivar_object 208.7 194.3 93.10% str_concat 52.6 52.2 99.24% throw 23.8 24.1 101.26% -------------- ------------ ------------ --------------- ``` It seems like the performance impact of generating and registering the debug info is marginal. -- https://bugs.ruby-lang.org/

[ruby-core:114250] [Ruby master Bug#19778] mkmf.rb pkg_config() interaction with RbConfig::CONFIG["cflags"]
by rhenium (Kazuki Yamaguchi) 17 Oct '23

Issue #19778 has been reported by rhenium (Kazuki Yamaguchi). ---------------------------------------- Bug #19778: mkmf.rb pkg_config() interaction with RbConfig::CONFIG["cflags"] https://bugs.ruby-lang.org/issues/19778 * Author: rhenium (Kazuki Yamaguchi) * Status: Open * Priority: Normal * ruby -v: ruby 3.3.0dev (2023-07-21T09:38:29Z master 22f9735587) [x86_64-linux] * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- (This was first reported at https://github.com/ruby/openssl/issues/650: The extension's build breaks in a strange way if `RbConfig::CONFIG["*flags"]` contains the path of an OpenSSL installation but `pkg-config` returns the path of a different OpenSSL installation) Commit commit:097c3e9cbbf23718371f08c24b2d2297b039f63f ("mkmf.rb: -I flags to $INCFLAGS", Ruby 2.2) changed how mkmf's `pkg_config()` handles the result of the `pkg-config` command. It now stores the `-I` flags in $INCFLAGS and others in $CFLAGS. mkmf generates a Makefile that compiles source files with: $(CC) $(INCFLAGS) $(CPPFLAGS) $(CFLAGS) and link the final library with: $(LDSHARED) -o $@ $(OBJS) $(LIBPATH) $(DLDFLAGS) $(LOCAL_LIBS) $(LIBS) This "new" behavior of `pkg_config()` is problematic when `RbConfig::CONFIG["{C,CPP}FLAGS"]` also provide `-I` flags and `RbConfig::CONFIG["LDFLAGS"]` provides the matching `-L` flags -- for example, if Ruby is compiled with `./configure --with-opt-dir=<dir>`. This would end up with compiling sources with [...] -I<from pkg-config> -I<from RbConfig> [...] and then linking with [...] -L<from RbConfig> -L<from pkg-config> [...] This doesn't seem right. I don't know which should come earlier, but the order should be consistent. The commit in question clearly describes the change in the commit message, but it doesn't have a linked issue. What is it intended for? Also, what is $INCFLAGS? On the other hand, `dir_config()` would prepend `-I` flags to $CPPFLAGS and `-L` flags to $LIBPATH, so it doesn't have issues with flags from `RbConfig`, albeit in a differently way. -- https://bugs.ruby-lang.org/

[ruby-core:114181] [Ruby master Bug#19767] [Not really a bug, but more a not ideal notification] "historical binary regexp match" when using the "n" modifier in a ruby regex

Issue #19767 has been reported by rubyFeedback (robert heiler). ---------------------------------------- Bug #19767: [Not really a bug, but more a not ideal notification] "historical binary regexp match" when using the "n" modifier in a ruby regex https://bugs.ruby-lang.org/issues/19767 * Author: rubyFeedback (robert heiler) * 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 ---------------------------------------- To get my knowledge about ruby regexes up-to-date I have been going through this tutorial/book here at: https://learnbyexample.github.io/Ruby_Regexp/unicode.html One example they provide is this, with some odd characters: 'fox:αλεπού'.scan(/\w+/n) This will match the found word ("fox"), but it also reports the following warning: warning: historical binary regexp match /.../n against UTF-8 string Now: this may be obvious to others, but to me personally I am not sure what a "historical" binary regexp match actually is. I assume it may have meant that this was more used in the past, and may be discouraged now? Or is something else meant? What does "historical" mean in this context? I may not be the only one who does not fully understand the term historical. Most of ruby's warnings are fairly easy to understand, but this one seems odd. Right now I do not know whether we can use the "n" modifier in a regex - not that I really have a good use case for it (I am using UTF-8 these days, so I don't seem to need ASCII-8BIT anyway), but perhaps the warning could be changed a little. I have no good alternative suggestion how it can be changed, largely because I do not know what it actually means, e. g. what is "historical" about it (but, even then, I'd actually recommend against using the word "historical" because I don't understand what it means; deprecated is easy to understand, historical does not tell me anything). Perhaps it could be expressed somewhat differently and we could get rid of the word "historical" there? Either way, it's a tiny issue so I was not even sure whether to report it. But, from the point of view of other warnings, I believe the term "historical" does not tell the user enough about what the issue is here.

I'm trying to improve my Ruby library to support transfer-based fibers (https://github.com/rmosolgo/graphql-ruby/pull/4322) To test parallel I/O, I'm using `system("sleep #{duration}")`, but this causes a segfault sometimes. I'd love to find a way to keep developing this feature but I'm not sure where to go next. I have attached a script which replicates the bug and I have attached the full segfault error dump. I encountered this error by running: ``` ruby fiber_bug.rb 2>out.txt ``` Does that help debug? Please let me know if I can provide anything else that'd be helpful. ---Files-------------------------------- out.txt (121 KB) fiber_bug.rb (624 Bytes) -- https://bugs.ruby-lang.org/

Our only outstanding question before merging it is about naming. How should we expose the public API for YARP's compile method? Potential suggestions: 1. YARP.compile 2. RubyVM::InstructionSequence.compile(yarp: true) 3. RubyVM::InstructionSequence.compile_yarp 4. Any of the above options, with a name other than yarp (please suggest an alternative) Regarding option 1, which would mirror `YARP.parse`, is the top level constant `YARP` acceptable? cc @matz @ko1 -- https://bugs.ruby-lang.org/
