From c2870b699eb899f358b843c2d706ce8ca89b2bf4 Mon Sep 17 00:00:00 2001 From: Victor Stinner Date: Thu, 31 May 2018 07:35:03 +0200 Subject: [PATCH] bpo-33532: Fix multiprocessing test_ignore() (GH-7262) (#7266) Fix test_ignore() of multiprocessing tests like test_multiprocessing_forkserver: use support.PIPE_MAX_SIZE to make sure that send_bytes() blocks.
