#471 extends the assembler test suite to also test xfs and btrfs filesystems
in raw and qemu assemblers. However, this change leads to long running times
of this suite.
The running time of these test consist of 3 main steps:
1) Building the build pipeline
2) Building the stages
3) Running the assembler
There are two optimization approaches:
1) Caching
OSBuild supports caching, therefore it's possible to cache results of first
two steps.
2) Minimizing the operating system tree
Assemblers don't care about the image contents. Therefore, it's possible
to create just a small tree which would be used to test the assemblers.
This should lead to speed up in the step 2 (smaller tree should be built
quicker) and in step 3 (big part of assembling is just copying files over
to the image).
This commit implements the second approach. A new test manifest is now added,
which just installs the filesystem package and its dependencies and this tree
is then labeled. This solution was chosen, so that the assemblers get
something that looks as a proper filesystem tree but also can be built pretty
quickly.
Before this change, the test_rawfs method with #471 merged ran for 842 seconds.
After this change, it ran for 391 seconds.
Verify the rpm-ostree.input hash is set correctly for the repository
itself as well. This will in turn also verify that the repository
is existent and can be accessed.
Using the network block device (nbd) kernel module to test all
the non-raw image formats often caused tests to fail due to nbd
not being stable itself (see below).
Instead convert non-raw images to the raw format via qemu-img
convert and mount those with loop-back devices. All the testing
code itself stays the same.
Example nbd error messages:
kernel: block nbd15: NBD_DISCONNECT
kernel: block nbd15: Disconnected due to user request.
kernel: print_req_error: 89 callbacks suppressed
kernel: blk_update_request: I/O error, dev nbd15, sector 0 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 0
kernel: buffer_io_error: 134 callbacks suppressed
kernel: Buffer I/O error on dev nbd15, logical block 0, async page read
kernel: blk_update_request: I/O error, dev nbd15, sector 1 op 0x0:(READ) flags 0x0 phys_seg 7 prio class 0
Split up the partition table test into reading the partition table
and then asserting it has the correct entries. Prepares the usage
of the partition information later.
Move the last remaining test into the correct subdir. With this done,
all our tests run in one of the 3 groups:
* `make test-src`
Run tests against the source-code, including linters.
* `make test-mod`
Run unit-tests on the individual python modules. This needs no
special permissions (unless noted in each test) or runtime
environments. It is meant to be fast and easy to run in all
circumstances.
* `make test-run`
Run tests that execute the osbuild pipeline. This requires
superuser privileges and will likely take a while. Furthermore,
this might produce large artifacts.
