From 3192fad7f789404dce6041d01400db3c16a0b5d1 Mon Sep 17 00:00:00 2001 From: Nir Soffer Date: Sat, 29 Aug 2020 02:21:51 +0300 Subject: [PATCH] qemu-iotests: Merge FilePaths and FilePath FilePath creates now one temporary file: with FilePath("a") as a: Or more: with FilePath("a", "b", "c") as (a, b, c): This is also the behavior of the file_path() helper, used by some of the tests. Now we have only 2 helpers for creating temporary files instead of 3.
