Hi Eric,

https://80x24.org/perl-libnet.git/commit/?h=nntp-compress&id=6f1c2c717f6e2858e5d62073c47efe11e597e067
"sysread may call SSL_read, and SSL_read may buffer extra
data in userspace which can be returned via sysread without
making another read(2) syscall. This makes it it possible for
select() to block indefinitely since select() only knows about
buffers in the kernel, not userspace."
Nice catch! Hopefully it will be fixed in Net::NNTP.
For your information, INN also suffered from that annoying bug in
earlier 2.4.x versions. That was why we finally by-passed the use of
select() because it generated dead connections. And also implemented a
timeout alarm signal around SSL_read().

+ croak("NNTP connection already compressed ($comp)") if $comp;
+ croak("$alg not supported (only 'DEFLATE')") if $alg ne 'DEFLATE';
Note that these messages have different response codes: 502 for the
first one, 503 for the last one.
+ can_deflate() or die $nodeflate_warn;
and
+ $err == Z_OK or die "Inflate->new failed: $err\n";
and
+ $err == Z_OK or die "Deflate->new failed: $err\n";
It should be a 403 response code, and then the connections goes on
uncompressed (same remark found in your patch against public-inbox-nntpd).

Isn't Cleanfeed good enough for your needs?
http://www.mixmin.net/cleanfeed/
I am also aware of a use of SpamAssassin with INN. Maybe it would
better fit your expectations?
