Infrastructure

Fixes

Version 3.4.3

This is mostly a bug fix release, mainly for bugs found by @agroce using tstl.

New Features

  • added support for path-like objects as arguments in create_file(), create_dir(), create_symlink(), add_real_file() and add_real_directory() (Python >= 3.6, see #409)

This is a bug fix only release.

Fixes

  • add_real_directory does not work after chdir (see #355)

Version 3.4

This version of pyfakefs does not support Python 2.6. Python 2.6 users must use pyfakefs 3.3 or earlier.

New Features

  • Added possibility to map real files or directories to another path in the fake file system (see #347)

    • Dynamic loading of modules after setup is now on by default and no more considered experimental (see #340)
  • Added support for file descriptor path parameter in os.scandir (Python >= 3.7, Posix only) (see #346)
  • Added support to fake out backported scandir module (#332)
  • IOError/OSError exception messages in the fake file system now always start with the message issued in the real file system in Unix systems (see #202)

Infrastructure

  • Changed API to be PEP-8 conform (#186). Note: The old API is still available.
  • Removed Python 2.6 support (#293)
  • Added usage documentation to GitHub Pages
  • Added contributing guide
  • Added flake8 tests to Travis CI

Fixes

  • Links in base path in os.scandir shall not be resolved (#350)

  • Correctly handle newline parameter in open() for Python 3, added support for universal newline mode in Python 2 (#339)
  • Fixed handling of case-changing rename with symlink under MacOS (#322)
  • Creating a file with a path ending with path separator did not raise (#320)

  • Unittest mock didn't work after setUpPyfakefs (#334)
  • os.path.split() and os.path.dirname() gave incorrect results under Windows (#335)

Version 3.3

This is the last release that supports Python 2.6.

New Features

  • The OS specific temp directory is now automatically created in setUp() (related to #191). Note that this may break test code that assumes that the fake file system is completely empty at test start.
  • Added possibility to reload modules and switch on dynamic loading of modules after setup (experimental, see #248)
  • Added possibility to patch modules that import file system modules under another name, for example import os as '_os (#231)
  • Added support for dir_fd argument in several os functions (#206)
  • Added support for open file descriptor as path argument in os.utime, os.chmod, os.chdir, os.chown, os.listdir, os.stat and os.lstat (Python >= 3.3) (#205)
  • Added support for basic modes in fake os.open() (#204)
  • Added fake os.path.samefile implementation (#193)
  • Added support for ns argument in os.utime() (Python >= 3.3) (#192)
  • Added nanosecond time members in os.stat_result (Python >= 3.3) (#196)

Infrastructure

  • Added Travis CI tests for MacOSX (Python 2.7 and 3.6)
  • Added Appveyor CI tests for Windows (Python 2.7, 3.3 and 3.6)
  • Added auto-generated documentation for development version on GitHub Pages
  • Removed most of fake_filesystem_shutil implementation, relying on the patched os module instead (#194)
  • Removed fake_tempfile and fake_filesystem_glob, relying on the patched os module instead (#189, #191)

Fixes

  • Multiple fixes of bugs found using TSTL by @agroce (see about 100 issues with the TSTL label)
    • several problems with buffer handling in high-level IO functions
    • several problems with multiple handles on the same file
    • several problems with low-level IO functions
    • incorrect exception (IOError vs OSError) raised in several cases
    • Fake rename did not behave like os.rename in many cases
    • Symlinks have not been considered or incorrectly handled in several functions
    • A nonexistent file that has the same name as the content of the parent object was seen as existing
    • Incorrect error handling during directory creation
    • many fixes for OS-specific behavior
  • Also patch modules that are loaded between __init__() and setUp() (#199)
  • Creating files in read-only directory was possible (#203)

Version 3.2

New Features

  • The errors argument is supported for io.open() and os.open()
  • New methods add_real_file(), add_real_directory() and add_real_paths() make real files and directories appear within the fake file system. File contents are read from the real file system only as needed (#170). See example_test.py for a usage example.
  • Deprecated TestCase.copyRealFile() in favor of add_real_file(). copyRealFile() remains only for backward compatability. Also, some less-popular argument combinations have been disallowed.
  • Added this file you are reading, CHANGES.md, to the release manifest

Infrastructure

  • The mox3 package is no longer a prerequisite--the portion required by pyfakefs has been integrated into pyfakefs (#182)

Fixes

  • Corrected the handling of byte/unicode paths in several functions (#187)
  • FakeShutilModule.rmtree() failed for directories ending with path separator (#177)
  • Case was incorrectly handled for added Windows drives
  • pathlib.glob() incorrectly handled case under MacOS (#167)
  • tox support was broken (#163)
  • On Windows it was not possible to rename a file when only the case of the file name changed (#160)

Version 3.1

New Features

  • Added helper method TestCase.copyRealFile() to copy a file from the real file system to the fake file system. This makes it easy to use template, data and configuration files in your tests.
  • A pytest plugin is now installed with pyfakefs that exports the fake filesystem as pytest fixture fs.

Fixes

  • Incorrect disk usage calculation if too large file created (#155)

Version 3.0
