test: fix parsing the mksquashfs version number

2022-05-26T14:32:27Z

Testing with mksquasshfs 4.5.1 results in an error ValueError: could not convert string to float: '4.5.1' Version 4.10 would be considered to be lower than 4.4. Fixes: 04c9813e951f ("test/py: rewrite common tools for SquashFS tests") Signed-off-by: Heinrich Schuchardt

Some builds of squashfs-tools append version string with "-git" or similar. The float() conversion will fail in this case. Improve the code to only convert to float() the string before the '-' character. Signed-off-by: Marek Behún Reviewed-by: Simon Glass Reviewed-by: Joao Marcos Costa

Add more details to test cases by comparing each expected line with the command's output. Add new test cases: - sqfsls at an empty directory - sqfsls at a sub-directory Reviewed-by: Simon Glass Tested-by: Simon Glass [on sandbox] Signed-off-by: Joao Marcos Costa

test/py: rewrite sqfsload command test suite

2021-07-05T19:29:10Z

The previous strategy to know if a file was correctly loaded was to check for how many bytes were read and compare it against the file's original size. Since this is not a good solution, replace it by comparing the checksum of the loaded bytes against the original file's checksum. Add more test cases: files at a sub-directory and non-existent file.

test/py: Wait for guestmount worker to exit after running guestunmount

2021-07-05T19:28:32Z

Some filesystem tests are failing when their image is prepared with guestmount, but succeeding if loop mounts are used instead. The reason seems to be a race condition the guestmount(1) manual page explains: When guestunmount(1)/fusermount(1) exits, guestmount may still be running and cleaning up the mountpoint. The disk image will not be fully finalized. This means that scripts like the following have a nasty race condition: guestmount -a disk.img -i /mnt # copy things into /mnt guestunmount /mnt # immediately try to use 'disk.img' ** UNSAFE ** The solution is to use the --pid-file option to write the guestmount PID to a file, then after guestunmount spin waiting for this PID to exit. The Python standard library has an os.waitpid() function for waiting a child to terminate, but it cannot wait on non-child processes. Implement a utility function that can do this by polling the process repeatedly for a given duration, optionally killing the process if it won't terminate on its own. Apply the suggested solution with this utility function, which makes the failing tests succeed again. Signed-off-by: Alper Nebi Yasak Reviewed-by: Simon Glass

test/py: Use loop mounts if guestmount fails in filesystem tests

2021-07-05T19:28:32Z

If guestmount isn't available on the system, filesystem test setup falls back to using loop mounts to prepare its disk images. If guestmount is available but fails to work, the tests are immediately skipped. Instead of giving up on a guestmount failure, try using loop mounts as an attempt to keep tests running. Also stop checking if guestmount is in PATH, as trying to run a missing guestmount can now follow the same failure codepath and fall back to loop mounts anyway. Signed-off-by: Alper Nebi Yasak
