effective group ID or to group ID of its parent directory.
- Add some comments from POSIX.
- Verify that after successful O_TRUNC open, size is equal to 0.
he is the file's owner, he can't set set-gid bit.
POSIX requires to return 0 and clear the bit, but FreeBSD returns
EPERM for UFS in such case. For now do the same in ZFS.
Almost all regression tests are based on very flexible fstest tool.
They verify correctness (POSIX conformance) of almost all file
system-related system calls.
The motivation behind this work is my ZFS port and POSIX, who doesn't
provide free test suites.
Runs on: FreeBSD/UFS, FreeBSD/ZFS, Solaris/UFS, Solaris/ZFS
To try it out:
# cd fstest
# make
# find tests/* -type d | xargs prove
