07:41 PM Bug #21710: Segfault when reading object_id after it is set inside RUBY_INTERNAL_EVENT_NEWOBJ
- I don't think we should support this (at least not long term, I'm fine if it is patched for Ruby 4.0.0). `object_id` has always potentially allocated (either to enlarge the backing hashes, or to make a BIGNUM on 32-bit). It's only in the...

02:49 PM Bug #21718: TypeError:wrong argument type ... (expected Array)
- Ignoring `method_missing` in this case or wrapping the non-array object in an array are the only workarounds I can think of. I don't believe ruby ever ignores `method_missing` like this, so it would be a bit different to do it here.

When we get to this point, we must not just have parsed a command call, always consuming the `=>` is not correct.

04:48 PM Revision dd489ee9 (git): [ruby/openssl] asn1: refactor converting ASN1_OBJECT to string
- ruby/openssl exposes OIDs to Ruby as strings in many places, but the
conversion logic has been duplicated and the behavior is inconsistent.
There are mainly two patterns:
- Returns the short name associated with the OID/NID, or the dot... -
- obj_to_asn1obj() in ossl_ts.c and ossl_asn1.c are identical. Let's
remove one in ossl_ts.c.
eASN1Error can now be made static to ossl_asn1.c.
https://github.com/ruby/openssl/commit/dcb05c40c2 -
- EC_GROUP_get_curve_name() returns NID_undef when OpenSSL does not
recognize the curve and there is no associated OID.
Handle this case explicitly and return nil instead of the string
"UNDEF", which should not be exposed outside the exte... -
- We can then pass them to the decoder to save having to parse
the string again.
