Describe the bug
After updating from pyfakefs 5.6.0 to 5.7.0 the following error occurs on flock with fcntl.LOCK_SH, fcntl.LOCK_UN and LOCK_EX.

The error does not occur on version 5.6.0

self = <pyfakefs.fake_io.FakeFcntlModule object at 0x7f237a9ba760>, name = 'LOCK_SH'

    def __getattribute__(self, name):
        """Forwards any unfaked calls to the standard fcntl module."""
        fs: FakeFilesystem = object.__getattribute__(self, "filesystem")
        fnctl_module = object.__getattribute__(self, "_fcntl_module")
        if fs.patcher:
            if is_called_from_skipped_module(
                skip_names=fs.patcher.skip_names,
                case_sensitive=fs.is_case_sensitive,
            ):
                # remove the `self` argument for FakeOsModule methods
                return getattr(fnctl_module, name)
    
>       return object.__getattribute__(self, name)
E       AttributeError: 'FakeFcntlModule' object has no attribute 'LOCK_SH'

How To Reproduce

import fcntl
from os import path


def lock():
    with open('lock_file', 'a+') as lock_file:
        fcntl.flock(lock_file, fcntl.LOCK_SH)
        fcntl.flock(lock_file, fcntl.LOCK_UN)

def test_lock(fs):
    lock()

Thanks! I can't think of any changes in the last version that would cause that, but obviously there is something I miss...

[mrbean-bremen]

Ok, found the problem - I did indeed miss this during the review, and there was no test in place that caught that..

[mrbean-bremen]

Should be fixed in main now, please check!
I'll probably wait a couple of days, in case something else comes up, and make a patch release.

[sj98ta]

I confirmed that it now works as expect. Thanks for the quick fix!

[mrbean-bremen]

FYI: I made the patch release yesterday.
