File.open ignores flags option

[mhib]

Code to reproduce the issue:

File.open("not_existing_file", flags: File::CREAT | File::WRONLY)

This line returns a File both on CRuby and JRuby, but throws an error on TruffleRuby.

My ruby --version:

truffleruby 22.3.0, like ruby 3.0.3, GraalVM CE Native [x86_64-darwin]

Thank you for the report.

I can repro on truffleruby-dev:

$ ruby -e 'File.open("not_existing_file", flags: File::CREAT | File::WRONLY)'
<internal:core> core/errno.rb:48:in `handle': No such file or directory - not_existing_file (Errno::ENOENT)
	from <internal:core> core/io.rb:898:in `sysopen'
	from <internal:core> core/file.rb:1216:in `initialize'
	from <internal:core> core/io.rb:674:in `open'
	from -e:1:in `<main>'
