Subject: libreadline7: readline() interferes with blocked SIGALRM
Date: Thu, 26 Jan 2017 18:15:41 -0500
Package: libreadline7
Version: 7.0-1
Severity: normal
Tags: patch upstream
Forwarded: https://lists.gnu.org/archive/html/bug-readline/2017-01/msg00002.html
Control: affects -1 twinkle-console
readline() in 7.0-1 calls pselect() with an empty sigmask, thereby
unblocking all signals beforehand. This causes twinkle-console to abort
after a few seconds, due to a now-unblocked SIGALRM being delivered to
the main thread, instead of the one calling sigwait().
Upstream has posted a one-line patch to fix this issue. Is it too late
to have it applied before the freeze? Otherwise, twinkle-console will
be pretty much unusable in stretch.

Hi Matthias,
Could you apply upstream patch 003 to resolve this issue?
https://ftp.gnu.org/gnu/readline/readline-7.0-patches/readline70-003
Please let me know if you are busy, in which case I can offer to
upload an NMU (via sponsorship) and request an unblock for stretch.
Regards,
Peter
