From 22e29bcea12ccf0e127b91917d959c69bebbd952 Mon Sep 17 00:00:00 2001 From: Vladimir Sementsov-Ogievskiy Date: Thu, 23 Dec 2021 17:01:29 +0100 Subject: [PATCH] iotests.py: qemu_img*("create"): support IMGOPTS='compression_type=zstd' Adding support of IMGOPTS (like in bash tests) allows user to pass a lot of different options. Still, some may require additional logic. Now we want compression_type option, so add some smart logic around it: ignore compression_type=zstd in IMGOPTS, if test want qcow2 in compatibility mode. As well, ignore compression_type for non-qcow2 formats. Note that we may instead add support only to qemu_img_create(), but that works bad: 1. We'll have to update a lot of tests to use qemu_img_create instead of qemu_img('create'). (still, we may want do it anyway, but no reason to create a dependancy between task of supporting IMGOPTS and updating a lot of tests) 2. Some tests use qemu_img_pipe('create', ..) - even more work on updating 3. Even if we update all tests to go through qemu_img_create, we'll need a way to avoid creating new tests using qemu_img*('create') - add assertions.. That doesn't seem good. So, let's add support of IMGOPTS to most generic qemu_img_pipe_and_status().
