Research direction

Reproduce the two failures with ruby.wasm 2.7.0, starting with the require examples for tempfile.rb and digest/sha1. Review the referenced tempfile and digest pull requests and the Ruby commit, then compare behavior with Ruby 3.3. Done means both libraries load successfully in the head WebAssembly build.

Written by the indexing model from the issue text.

Description

I'm actively experimenting with the head Ruby builds (mostly due to #555) and collecting some compatibility
issues compared to 3.3 release here.

Gem/lib versions:

  • ruby_wasm: 2.7.0
  • js: 2.7.0

This commit broke loading tempfile.rb: https://github.com/ruby/ruby/commit/136cbf04419acf993357701e54712f921a294355

require "tempfile"

# => 'File#initialize': No such file or directory @ rb_sysopen - /dev/null (Errno::ENOENT)

Not sure how to properly handle /dev/null in Wasm, though; maybe, we should return nil for IO::NULL and check for nil-ness whenever it's used 🤔

require "digest/sha1"

#=> <internal:/usr/local/lib/ruby/3.4.0+0/rubygems/core_ext/kernel_require.rb>:136:in 'Kernel#require': rb_digest_wrap_metadata not found (LoadError)
<internal:/usr/local/lib/ruby/3.4.0+0/rubygems/core_ext/kernel_require.rb>:136:in 'Kernel#require'
eval:3:in '<main>'
-e:in 'Kernel.eval'

Worked fine in 3.3.
