Changed test helper to take advantage of it. * Still outstanding: Several hard-coded references to /tmp appear in the tests. * Liberation-Mono is not commonly installed on Windows, and even when it is, the font has a different name. Provide a fall-back for Windows fonts. (Considered the use of a 3rd party tool to help select, but seemed overkill.) * Help tests run on Windows - allow some flexibility in versions. Building/finding binaries on Windows is non-trivial. Aallow some flexibility in the path levels. (I don't want to force existing users to upgrade, but new users should be allowed the later patches.) * Issue 596: Add initial support for closing clips. Doesn't do anything yet. The work is done in the subclasses that need it. Also supports context manager, to allow close to be implicitly performed without being forgotten even if an exception occurs during processes. * Issue 596: Update doctest examples to call close. Demonstrate good practice in the examples. * More exception details for easier debugging of ImageMagick issues. Especially for Windows. * Issue #596: Move away from expecting/requiring __del__ to be called. The work should be done in close(). Deleting can be left for the garbage collector. * Issue #596: Move ffmpeg_writer to using close. Again, avoid depending on __del__. Add a context manager interface. Use it lower down. * Issue #596: Update ffmpeg_audiowriter to support close/context manager. * Issue #596: Move AudioFileClip to use close(), away from __del__. Was concerned that lambda might include a reference to reader that wasn't cleaned up by close, so changed it over to an equivalent self.reader. Probably has no effect, but feels safer. * Issue #596: Support close() on CompositeVideoClip. Note: It does NOT close all the subclips, because they may be used again (by the caller). It is the caller's job to clean them up. But clips created by this instance are closed by this instance. * Issue #596: Add tests to see if this issue has been repaired. test_resourcereleasedemo exercises the path where close is not called and demonstrates that there is a consistent problem on Windows. Even after this fix, it remains a problem that if you don't call close, moviepg will leak locked files and subprocesses. [Because the problem remains until the process ends, this is included in a separate test file.] test_resourcerelease demonstrates that when close() is called, the problem goes away. * Issue #596: Update tests to use close(). * Without tests changes, many of these existing tests do not pass on Windows. * Further to PR #597: Change to Arial Helvetica wasn't recognised by ImageMagick. Changing to another arbitrary font that should be available on all Windows machines. * Issue #596 and #598: Updated test to support close(). Also changed test to meet Issue #598, but that is also being done in PR#585, so will require a merge. * Revert "More exception details for easier debugging of ImageMagick issues." This reverts commit dc4a16afb6c5a7da204e7a63ea7257c8f8a46d6c. I bundled too much into one commit. Reverting and reapplying as two separate commits for better history. * Issue #599: test_6 doesn't test anything. Removed as it was crashing on Windows, achieving nothing on Linux. * Issue #596: Move comment to avoid incorporate into documents. * Issue #596: Add usages tips to documentation. * Clip class missing from reference documents. Due to failing import. * Copy-edit: Clumsy sentence in documentation. * Fix failing doctest. * Issue 596: Add initial support for closing clips. * Add key support for close() * FFMPEG_VideoWriter and FFMPEG_AudioWriter: Support close() and context managers. * Clip: support close() and context manager. Doesn't do anything itself. The work is done in the subclasses that need it. * Clip subclasses: Overrride close. * Move away from depending on clients calling__del__(). Deleting can be left to Garbage Collector. * CompositeVideoClip: Note: Don't close anything that wasn't constructed here. The client needs to be able to control the component clips. * AudioFileClip: Was concerned that lambda might include a reference to reader that wasn't cleaned up by close, so changed it over to an equivalent self.reader. Probably has no effect, but feels safer. * Update tests to use close(). * Note: While many tests pass on Linux either way, a large proportion of the existing unit tests fail on Windows without these changes. * Include changes to many doctest examples - Demonstrate good practice in the examples. * Also, migrate tests to use TEMPDIR where they were not using it. * test_duration(): also corrected a bug in the test (described in #598). This bug is also been addressed in #585, so a merge will be required. * Add two new test files: * test_resourcereleasedemo exercises the path where close is not called and demonstrates that there is a consistent problem on Windows. Even after this fix, it remains a problem that if you don't call close, moviepg will leak locked files and subprocesses. Because the problem remains until the process ends, this is included in a separate test file.] * test_resourcerelease demonstrates that when close() is called, the problem goes away. * Update documentation to include usage tips for close() Not included: * Example code has not been updated to use close(). * Merge branch 'WindowsSupport' of C:\Users\xboxl\OneDrive\Documents\MyApps\moviepy with conflicts. * Neaten up output and PEP8 compliance. Also, make runnable directly (to help debugging) * Remove references to /tmp to allow to run on Windows. * Reference to PermissionError failing on Python 2.7. * Migrate to use requests to avoid certificate problems. Old versions of urlretrieve have old certificates which means one of the video downloads was failing. Also requires changes to setup.py, to come. * Clean up of dependencies. Including adding ranges, removing unnecessary entries, adding missing entries, adding environment markers, changing versions, and updating pytest parameter handling. * Simplification of Travis file - letting te setup.py do the heavy lifting Remove conditional installations repeating the rules in setup.py Remove some installation of test needs repeating the rules in setup.py Add testing of installation options. * Add Appveyor support. * Solve Issue 629. --- .travis.yml | 33 ++-- appveyor.yml | 161 ++++++++++++++++++ appveyor/run_with_env.cmd | 86 ++++++++++ docs/getting_started/efficient_moviepy.rst | 26 +++ moviepy/Clip.py | 38 ++++- moviepy/audio/io/AudioFileClip.py | 43 +++-- moviepy/audio/io/ffmpeg_audiowriter.py | 26 ++- moviepy/audio/io/readers.py | 3 +- moviepy/config.py | 13 +- moviepy/video/VideoClip.py | 1 + .../video/compositing/CompositeVideoClip.py | 14 ++ moviepy/video/io/VideoFileClip.py | 28 ++- moviepy/video/io/downloader.py | 18 +- moviepy/video/io/ffmpeg_reader.py | 13 +- moviepy/video/io/ffmpeg_writer.py | 45 ++--- moviepy/video/io/gif_writers.py | 9 +- moviepy/video/tools/subtitles.py | 3 +- setup.py | 53 ++++-- tests/download_media.py | 18 +- tests/test_ImageSequenceClip.py | 10 +- tests/test_PR.py | 40 +++-- tests/test_TextClip.py | 12 +- tests/test_VideoFileClip.py | 45 ++--- tests/test_Videos.py | 17 +- tests/test_compositing.py | 39 +++-- tests/test_fx.py | 59 +++---- tests/test_helper.py | 14 +- tests/test_issues.py | 67 ++++---- tests/test_misc.py | 12 +- tests/test_resourcerelease.py | 53 ++++++ tests/test_resourcereleasedemo.py | 75 ++++++++ tests/test_tools.py | 12 -- 32 files changed, 822 insertions(+), 264 deletions(-) create mode 100644 appveyor.yml create mode 100644 appveyor/run_with_env.cmd create mode 100644 tests/test_resourcerelease.py create mode 100644 tests/test_resourcereleasedemo.py diff --git a/.travis.yml b/.travis.yml index a6a0d0db0..7976b104e 100644 --- a/.travis.yml +++ b/.travis.yml @@ -8,23 +8,36 @@ python: - "3.4" - "3.5" - "3.6" -# command to install dependencies + before_install: - sudo add-apt-repository -y ppa:kirillshkrogalev/ffmpeg-next - sudo apt-get -y -qq update - sudo apt-get install -y -qq ffmpeg - mkdir media + + # Ensure PIP is up-to-date to avoid warnings. + - python -m pip install --upgrade pip + # Ensure setuptools is up-to-date to avoid environment_markers bug. + - pip install --upgrade setuptools + # The default py that is installed is too old on some platforms, leading to version conflicts + - pip install --upgrade py pytest + install: - - if [[ $TRAVIS_PYTHON_VERSION == '3.4' || $TRAVIS_PYTHON_VERSION == '3.5' || $TRAVIS_PYTHON_VERSION == '3.6' ]]; then pip install matplotlib; pip install -U scikit-learn; pip install scipy; pip install opencv-python; fi - - if [[ $TRAVIS_PYTHON_VERSION == '2.7' ]]; then pip install scipy; pip install opencv-python; fi - - pip install coveralls - - pip install pytest-cov - - python setup.py install -# command to run tests -before_script: - - py.test tests/ --cov -script: py.test tests/ --doctest-modules -v --cov moviepy --cov-report term-missing + - echo "No install action required.
