Release Notes

pytest-dev/pyfakefs (pyfakefs)

v6.2.0

Compare Source

Changes the MRO for file wrappers.

Changes

• fake file wrappers now derive from io.TextIOBase or io.BufferedIOBase,
  so that isinstance-checks for these classes succeed
  (see #​1307
  and #​484)

Fixes

• route some pseudo-devices to the system instead of patching them; this ensures
  that os.urandom and related functions work correctly with PyPy
  (see #​1300)
• fake file seek method did not return the location in the file
  (see #​1304)
• make sure case sensitivity is correctly set for fake posix paths
  in hash(), Path.match and Path.full_match
  (see #​1308)

Infrastructure

• use newest pytest for testing in CI

v6.1.6

Compare Source

Follow-up bugfix release for 6.1.5.

Fixes

• os.path.realpath did not correctly handle some absolute paths under Windows
  (previous fix was incomplete, see #​1296)

v6.1.5

Compare Source

Minor bugfix release.

Fixes

• os.path.realpath did not resolve symlinks under Windows
  (see #​1296)

v6.1.4

Compare Source

Fixes incompatibility with VCCode unittest runner.

Fixes

• expanduser now correctly handles paths besides home and different separators
  (see #​1289)
• avoid faking filesystem in VSCode unittest runner
  (see #​1285)

v6.1.3

Compare Source

Minor bugfix release.

Fixes

• handle expanduser() and home() correctly in cross OS usage
  (see #​1289)

v6.1.2

Compare Source

Fixes a regression caused by the introduced weakrefs.

Fixes

• do not use weakrefs for filesystem objects in fake modules
  (see #​1284)

v6.1.1

Compare Source

Fixes a packaging issue in latest version.

Fixes

• fixed packaging issue: tests had not been added to sdist
  (see #​1278)

v6.1.0

Compare Source

Changes back-link references to weak references.

Changes

• added more support for PyPy 3
• Caution: many back-link references have been replaced by weak references;
  this may have unwanted consequences (crashes) for some untested workflows

Infrastructure

• added PyPy 3.11 to CI, added PyPy builds for all OSes
• use only pyproject.toml for dependencies, moved tox configuration into pyproject.toml

Fixes

• fixed a problem accessing size from a FakeFileWrapper object
  (see #​1276)
• fixed a problem with readable raising an error on a file object.
  (see #​1265)
• avoid memory accumulation in consecutive tests by using weak references
  (see #​1267)

v6.0.0

Compare Source

Removes some deprecated functionality, removes support for Python < 3.10.

Breaking Changes

• removed support for Python versions < 3.10; patch releases based on pyfakefs 5.10
  supporting older versions may be made on demand
• removed support for patching legacy modules scandir and pathlib2
• changed the default for FakeFilesystem.shuffle_listdir_results to True to reflect
  the real filesystem behavior

Changes

• added some support for Python 3.15a3

Fixes

• fixes a problem with Path type hints using the pipe symbol in wrapped functions
  inside an fs dependent fixture (see #​1242)
• fixes problem with new coverage in Python 3.14 using the fake filesystem
  (see #​1245)

Documentation

• added project information to documentation pages

Infrastructure

• added CI tests for Python 3.15

v5.10.2

Compare Source

Fixes a problem with pathlib.glob in Python 3.14.

Fixes

• fixed pathlib.glob() for Python 3.14 (see #​1239)

v5.10.1

Compare Source

Fixes a regression introduced in version 5.9.0.

Fixes

• fixed a deadlock in shutil.copytree if copying using an shutil function as
  copy_function argument (see #​1235)

v5.10.0

Compare Source

Adds official support for Python 3.14. Last minor version before the 6.0 release.

Changes

• the errno codes set in OSError have changed for some specific error conditions
  in Windows 11/Windows Server 2025; pyfakefs now matches this behavior
  instead of the previous behavior under Windows 10
• added official support for Python 3.14

Enhancements

• added support for os.readinto in Python 3.14
• added support for pathlib.copy and pathlib.copy_into in Python 3.14

Fixes

• fixes patching of Debian-specific tempfile in Python 3.13 (see #​1214)

v5.9.3

Compare Source

Fixes a utility method.

Changes

• a warning is now issued if trying to create a nested fake filesystem with custom arguments
  (custom arguments are ignored in this case, as the existing fake filesystem is used)

Fixes

• fixed fake_filesystem.add_package_metadata that had never worked correctly
  (see #​1205)

Infrastructure

• updated the package build-system minimum version to setuptools v61.2 and higher

v5.9.2

Fixes

• fixed handling of added strict argument in Python 3.9.23
• make sure test files are packaged (see #​1186)

v5.9.0

Compare Source

Adds support for an API change in latest Python patch releases.

Changes

• the message from an OSError raised in the fake filesystem has no longer the postfix
  "in the fake filesystem" (see #​1159)
• changed implementation of FakeShutilModule to prepare it for usage without the patcher
  (see #​1171)

Enhancements

• added convenience function add_package_metadata to add the metadata of a given
  package to the fake filesystem (see #​1155)

Fixes

• fixed handling of dynamic imports from code in the fake filesystem in Python > 3.11
  (see #​1121)
• fixed workaround for recursion with pytest under Windows to ignore capitalization
  of pytest executable (see #​1096)
