Hi,
I'd like to report what seems to be a bug in the busybox's test command. I
use the official alpine:3 docker container.
The test -r does not return true even when the file is indeed readable
(testing by head command). Yes, the file has an unusual set of permissions,
but that does not restrict it from reading. Here's the output of the
interactive container shell session:
dd72078df6d2:/task/output/files$ ls -lad . .. cnb_rate_eur_czk.csv
drwxrwx--- 2 setup project 4096 Feb 11 18:33 .
drwxr-x--- 5 setup project 4096 Feb 11 18:33 ..
