09:23 AM Ruby Revision f272b3e2 (git): [ruby/openssl] ssl: fix NoMethodError on SAN dNSName with an empty label

Handle the empty label as a literal string.
OpenSSL::SSL::SSLSocket#post_connection_check can raise NoMethodError
when the server certificate contains a malformed subjectAltName
extension with a dNSName that starts with ".", such as ".e... rhenium (Kazuki Yamaguchi)

03:55 AM Ruby Revision 844a1675 (git): test/ruby/test_io.rb: do not set RLIMIT_NPROC

On my computer, setting RLIMIT_NPROC to the low value of 2048 prevents
the forked process from creating any new native threads and it causes
make test-all to hang forever.
Remove it, as it does not seem to serve any purpose here.

03:55 AM Ruby Revision 9bcca300 (git): test/ruby/test_process.rb: simplify testing spawn with long strings

test_aspawn_too_long_path just wants to verify that passing a very long
string to spawn does not cause a crash. Use an input string that is long
enough for this purpose and does not ends up with spawning too many
processes.

06:08 PM Ruby Bug #22424: IO#readpartial and IO#sysread should respect IO#timeout= value

06:07 PM Ruby Bug #22433: IO#sysread and IO#pread are inconsistent for length 0 and negative numbers

I've opened a GitHub PR: https://github.com/ruby/ruby/pull/19323 rhenium (Kazuki Yamaguchi)

06:01 PM Ruby Bug #22433 (Open): IO#sysread and IO#pread are inconsistent for length 0 and negative numbers

When the length is 0 and an output buffer is given, the buffer is not cleared correctly. [Bug #18421] fixed the same bug for `IO#readpartial` and `IO#read_nonblock`, but it omitted `IO#sysread` and `IO#pread`:

04:29 PM Ruby Revision 15467f68 (git): [ruby/openssl] ssl: align #puts with IO

Handle nested arrays in the arguments, similar to how IO#puts behaves.

04:29 PM Ruby Revision 1ec5306d (git): [ruby/openssl] ssl: align #putc with IO

Add the method. OpenSSL::Buffering already supports other
character-oriented methods such as #getc, #ungetc, or #readchar, and
this is the only missing method.

04:29 PM Ruby Revision 09d278a9 (git): [ruby/openssl] ssl: run test_pair.rb tests against IO objects

Run assertions in test_pair.rb against a pair of real socket objects
to catch unintended differences between SSLSocket and core IO behavior.
This is skipped for TruffleRuby until I figure out what's wrong.
