We’re pleased to announce that TruffleRuby 33.0.1 is now available. This is a bug fix release that notably adds support for structured event reporting in Rails 8.1 (and any other usage of Fiber storage). We’ve also addressed some non-UTF-8 encoding issues, Integer & Float ceil with negative precision, and mkmf.rb’s `—target-rbconfig`.

More details at:

https://github.com/truffleruby/truffleruby/releases/tag/graal-33.0.1

We recommend all TruffleRuby users upgrade. Available now in common Ruby installers.

@getajobmike @nirvdrum It's slow because it's a lot of code, about 5k lines of Ruby: https://github.com/djberg96/pr-zlib/blob/main/lib/pr/rbzlib.rb
And that would need to warmup and be JIT-compiled. Even after that it would still be slower than C due to richer Ruby semantics.
My take is low-level code like zlib are not a good fit for high-level languages.

Also direct translations from C to Ruby don't work so well, it'd need more work to be faster and more idiomatic.

@getajobmike @nirvdrum A long time ago TruffleRuby used https://github.com/djberg96/pr-zlib (because of no support for C extensions back then). But it's much slower and not fully compatible, so we switched to the zlib extension as soon as feasible.

@alexanderadam I also created https://github.com/truffleruby/truffleruby/issues/4084 to discuss it.

Consider Encoding::InvalidByteSequenceError instead of ArgumentError for not-multiple-of-width bytes in UTF-16/32 · Issue #4084 · truffleruby/truffleruby

See https://github.com/truffleruby/truffleruby/blob/5c85240d0f51254a1721327233ff9ba0619f4896/doc/user/compatibility.md#strings-in-utf-16-and-utf-32-encoding Currently it's an ArgumentError: $ ruby ...

@alexanderadam Any opinion if an EncodingError would be better?

BTW I found that ` "a".force_encoding("UTF-16")` fails but that shouldn't since UTF-16 is a dummy encoding and now equivalent to BINARY: https://github.com/truffleruby/truffleruby/issues/4083

@alexanderadam It seems I get email notifications now (for the first time), yeah :)

@tekknolagi @mgaudet Not sure it has a name but I would consider that reasoning/technique to be part of deoptimization and the key benefit of it (vs an explicit check and handling the case it fails in JITed code). It's the "don't need to merge back after a failed guard because of deoptimization".

@alexanderadam It comes from https://github.com/truffleruby/truffleruby/blob/5c85240d0f51254a1721327233ff9ba0619f4896/src/main/java/org/truffleruby/language/methods/TranslateExceptionNode.java#L115-L116, which could be changed.

I think the initial idea for ArgumentError is e.g. passing UTF-16LE to e.g. encode or force_encoding is an invalid encoding argument in that context if the String has an odd number of bytes.
