READLINE PATCH REPORT
=====================
Readline-Release: 7.0
Patch-ID: readline70-003
Bug-Reported-by: Frédéric Brière <[email protected]>
Bug-Reference-ID: <[email protected]>
Bug-Reference-URL:
http://lists.gnu.org/archive/html/bug-readline/2017-01/msg00002.html
Bug-Description:
Readline-7.0 uses pselect(2) to allow readline to handle signals that do not
interrupt read(2), such as SIGALRM, before reading another character. The
signal mask used in the pselect call did not take into account signals the
calling application blocked before calling readline().
Patch (apply with `patch -p0'):
