gh-90473: Skip and document more failing tests on WASI (GH-93436)
- Mark more ``umask()`` cases - ``dup()`` is not supported - ``/dev/null`` is not available - document missing features - mark more modules as not available

|
|||
``socket.gethostbyname()`` are not implemented and always fail.
|
||||
- ``chmod(2)`` is not available. It's not possible to modify file permissions,
|
||||
yet. A future version of WASI may provide a limited ``set_permissions`` API.
|
||||
- User/group related features like ``os.chown()``, ``os.getuid``, etc. are
|
||||
stubs or fail with ``ENOTSUP``.
|
||||
- File locking (``fcntl``) is not available.
|
||||
- ``os.pipe()``, ``os.mkfifo()``, and ``os.mknod()`` are not supported.
|
||||
- ``process_time`` does not work as expected because it's implemented using
|
||||
wall clock.
|
||||
- ``os.umask`` is a stub.
|
||||
- ``os.umask()`` is a stub.
|
||||
- ``sys.executable`` is empty.
|
||||
- ``/dev/null`` / ``os.devnull`` may not be available.
|
||||
- ``os.utime*()`` is buggy in WASM SDK 15.0, see
|
||||
[utimensat() with timespec=NULL sets wrong time](https://github.com/bytecodealliance/wasmtime/issues/4184)
|
||||
- ``os.symlink()`` fails with ``PermissionError`` when attempting to create a
|
||||
symlink with an absolute path with wasmtime 0.36.0. The wasmtime runtime
|
||||
uses ``openat2(2)`` syscall with flag ``RESOLVE_BENEATH`` to open files.
|
||||
The flag causes the syscall to reject symlinks with absolute paths.
|
||||
- ``os.curdir`` (aka ``.``) seems to behave differently, which breaks some
|
||||
``importlib`` tests that add ``.`` to ``sys.path`` and indirectly
|
||||
``sys.path_importer_cache``.
|
||||
- WASI runtime environments may not provide a dedicated temp directory.
