[mauricioszabo]

While I was trying to use Net::SFTP library, I found the following error:

Exception rb_str_drop_bytes not implemented

With backtrace:

Getting the same error when using the ASN1 layer of ruby-openssl (https://travis-ci.org/swisscom/ruby-netsnmp/jobs/567174660)

#1732 is a PR aiming to implement rb_str_drop_bytes.

[wangyin-git]

How about 'rb_io_set_nonblock'. I got a #<RuntimeError: rb_io_set_nonblock not implemented>

ruby version:
truffleruby 19.1.0, like ruby 2.6.2, GraalVM CE Native [x86_64-linux]

[eregon]

@wangyin-git We'll implement rb_io_set_nonblock, it's needed for async too IIRC.

rb_str_drop_bytes has been implemented in #1740, it will be in the next release.

For rb_io_set_nonblock, I split it in a separate issue: #1741.
