I sent the following message about a month ago, and now am forwarding to bug-guile so that we do not forget about it.
Mark From: Mark H Weaver <m...@netris.org> Subject: Likely bug in scm_port_poll Date: Tue, 18 Jun 2019 00:40:27 -0400 Message-ID: <87a7ef1p61....@netris.org> Cc: guile-de...@gnu.org To: Andy Wingo <wi...@pobox.com> Hi Andy, If you'd be willing to take a quick look at this, I'd be grateful. Probably a bug, but I feel uneasy that I might be overlooking something. scm_port_poll contains the following code: if (scm_i_string_contains_char (events, 'r')) c_events |= POLLIN; if (scm_i_string_contains_char (events, '!')) c_events |= POLLPRI; if (scm_i_string_contains_char (events, 'w')) c_events |= POLLIN; That second POLLIN should be POLLOUT, right? Thanks, Mark https://git.savannah.gnu.org/cgit/guile.git/tree/libguile/ports.c?h=stable-2.2&id=420c2632bb1f48e492a035c1d216f209734f45e6#n1423
