Issue #19592 has been reported by npic1 (Nat Pic1). ---------------------------------------- Bug #19592: Unable to statically link a single extension in 3.2.x and >3.1.4 https://bugs.ruby-lang.org/issues/19592 * Author: npic1 (Nat Pic1) * Status: Open * Priority: Normal * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- Hi, I need to statically link a single extension (not all of them) by adding it to ext/Setup. This worked until version 3.1.4 and 3.2.x. It appears that this change broke it: [https://bugs.ruby-lang.org/projects/ruby-master/repository/git/revisions/79… [https://github.com/ruby/ruby/pull/6756](https://github.com/ruby/ruby/pull/6…. I have attached a script to reproduce the issue. When running the script, `ldd` fails with: ``` ext/extinit.o: in function `Init_ext': extinit.c:(.text+0x10): undefined reference to `ruby_init_ext' ``` ---Files-------------------------------- ruby_static_test.sh (1.57 KB) -- https://bugs.ruby-lang.org/

[ruby-core:113782] [Ruby master Bug#19716] SystemStackError occurs too easily on Alpine Linux (due to small stack size reported by pthread_attr_getstacksize on musl libc)

Issue #19716 has been reported by alexdowad (Alex Dowad). ---------------------------------------- Bug #19716: SystemStackError occurs too easily on Alpine Linux (due to small stack size reported by pthread_attr_getstacksize on musl libc) https://bugs.ruby-lang.org/issues/19716 * Author: alexdowad (Alex Dowad) * Status: Open * Priority: Normal * ruby -v: ruby 3.1.4p223 (2023-03-30 revision 957bb7cb81) [x86_64-linux-musl] * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- This is the same problem previously reported against Ruby 2.5 in https://bugs.ruby-lang.org/issues/14387. I just ran into the same problem on Ruby 3.1.4, built on Alpine Linux 3.16. @hsbt stated in the previous thread (https://bugs.ruby-lang.org/issues/14387#note-28) > If you have this issue with Ruby 3.2, please file it with another issue. I hacked `stack_check` in gc.c to print the values of `STACK_START` and `STACK_END` on stack overflow; on the Alpine 3.16 host where this problem just occurred, the values printed were: > Start=0x7ffd0bf4f000, End=0x7ffd0bf32530 ...which shows that Ruby thinks the stack size is only 131072 bytes. On the other hand, `ulimit -s` shows a stack size limit of 8192kb. This Ruby 3.1.4 was built from unmodified source code downloaded from https://cache.ruby-lang.org; the build was configured using `CFLAGS='-march=native' ./configure --disable-install-doc`. The invocation of Ruby which blew the stack was `bundle exec rake db:migrate`, on a mid-sized Rails project. Regarding @ncopa's patch from #14387, @wanabe listed some things which should be done before it is merged into mainline Ruby: > Okay, The patch needs one or more proofs of its behaviour, like that: > > Original issue [ruby-dev:50421] has gone away. > Standard test codes run well. > test-all > ruby/spec > getrlimit works on some situations like: > on single thread > with multiple threads > with RLIMIT_STACK environment variable > getrlimit code of musl is implemented correctly as expected. > (But It's doubtful whether it can be. I guess that a proof of code soundness is very difficult.) > Some "real world" applications can work. > I think it is better example that that application(s) can't work without the patch. I am happy to help cover some of these points if the Ruby development team is still interested in merging @ncopa's patch. -- https://bugs.ruby-lang.org/

When I upgraded to Ruby 3.3.0, any Ruby script would crash immediately with a segfault. I haven't been able to reproduce it outside of fly.io. I created a repository with a basic rack app which crashes on fly.io.
