| Subject: | Warnings when fetching HTTPS URLs via NaHTTP |
The specific combination of
Net::Async::HTTP fetching 'https' URLS
IO::Async::Loop::EV
causes the warning
EV: error in callback (ignoring): Can't call method "sysread" on an undefined value at /home/leo/lib/perl5/IO/Async/Stream.pm line 977.
Using other loop implementations avoids the warning. Fetching plain HTTP URLs also avoids it.
