Version 0.5.0

Released on: 2019/05/20

New features:

  • New processor pooch.Decompress saves a decompressed version of the downloaded file. Supports gzip, lzma/xz, and bzip2 compression. Note: Under Python 2.7, lzma and bzip2 require the backports.lzma and bz2file packages as well. These are soft dependencies and not required to use Pooch. See Installing. (#78)
  • New processor pooch.Untar unpacks files contained in a downloaded tar archive (with or without compression). (#77)

Version 0.4.0

Released on: 2019/05/01

New features:

  • Add customizable downloaders. Delegate file download into separate classes that can be passed to Pooch.fetch. Created the HTTPDownloader class (used by default) which can also be used to download files that require authentication/login. (#66)
  • Add post-download processor hooks to Pooch.fetch. Allows users to pass in a function that is executed right before returning and can overwrite the file path that is returned by fetch. Use this, for example, to perform unpacking/decompression operations on larger files that can be time consuming and we only want to do once. (#59)
  • Add the Unzip post-download processor to extract files from a downloaded zip archive. Unpacks files into a directory in the local store and returns a list of all unzipped files. (#72)
  • Make the check_version function public. It’s used internally but will be useful in examples that want to download things from the pooch repository. (#69)

Maintenance:

  • Pin sphinx to version 1.8.5. New versions of Sphinx (2.0.*) are messing up the numpydoc style docstrings. (#64)

  • Make Pooch.get_url a public method to get the download URL for a given file (#55)

Version 0.1

Released on: 2018/08/20

  • Fist release of Pooch. Manages downloading sample data files over HTTP from a server and storing them in a local directory. Main features:
    • Download a file only if it’s not in the local storage.
    • Check the SHA256 hash to make sure the file is not corrupted or needs updating.
    • If the hash is different from the registry, Pooch will download a new version of the file.
    • If the hash still doesn’t match, Pooch will raise an exception warning of possible data corruption.
