From c7df3f19d22dc3c13f7ca64d7dc15a4389ee63b8 Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Thu, 17 Oct 2019 15:31:33 +0200 Subject: [PATCH] iotests: Introduce $SOCK_DIR Unix sockets generally have a maximum path length. Depending on your $TEST_DIR, it may be exceeded and then all tests that create and use Unix sockets there may fail. Circumvent this by adding a new scratch directory specifically for Unix socket files. It defaults to a temporary directory (mktemp -d) that is completely removed after the iotests are done. (By default, mktemp -d creates a /tmp/tmp.XXXXXXXXXX directory, which should be short enough for our use cases.) Use mkdir -p to create the directory (because it seems right), and do the same for $TEST_DIR (because there is no reason for that to be created in any different way).
