RuntimeError when call os.remove during os.scandir

• The Operating System
  macos 10.15

• The Python version
  3.7.5

• The Module version
  pytest 7.4.0
  pyfakefs 5.5.0

• A minimal example to reproduce the problem (preferably in the form of a failing test)

import os


def test_file_removed_during_scandir(fs):
    fs.create_file('/wls/1.log')
    fs.create_file('/wls/2.log')
    with os.scandir('/wls') as it:
        for entry in it:
            if entry.is_file():
                os.remove(entry.path)
    assert not os.path.exists('/wls/1.log')

• The stack trace in case of an unexpected exception.

    File ".../test.py", line 7, in test_file_removed_during_scandir
        for entry in it:
    File ".../pyfakefs/fake_scandir.py", line 149, in __next__
        entry = self.entry_iter.__next__()
RuntimeError: dictionary changed size during iteration

After modified code on fake_scandir.ScanDirIter.__init__ as blow, the test works.

    def __init__(self, filesystem, path):
        ...
        entries = self.filesystem.confirmdir(self.abspath, check_exe_perm=False).entries
        self.entry_iter = iter(list(entries))

@kingronjan - shall be fixed in main now. Will you need a new release?

[kingronjan]

There is no need for a new release, thank you.
