v0.16.2

Bug Fixes

• Remove raster_crs in _subset_shape. (#413)

v0.16.1

This is a patch fix release to explicitly drop Python 3.9 support in the metadata due to incompatibility with xarray. For release notes on this minor version, see https://github.com/roocs/clisops/releases/tag/v0.16.0.

Bug Fixes

• Dropped Python3.9 support in metadata due to incompatibility with xarray (#408).

Internal Changes

• Fixed an issue with the tox configuration that was causing the py3.10 environment to use the wrong Python version (#408).

v0.16.0

New Features

• clisops now officially supports Python 3.13 (#398).
• Version limitations have been lifted on xarray and numpy to support newer versions (#398).
  • Mark regrid tests as xfail which do not pass due to latest xarray version (#397).

Bug Fixes

• clisops.utils.dataset_utils
  • Fixed is_time to avoid memory overload (#397).

Internal Changes

• Pinned a few docs-related dependencies to compatible versions. Added sphinx-autodoc-typehints, sphinx-codeautolink, and sphinx-copybutton to the docs dependencies (#396).
• The LICENSE file has been adjusted to ensure it is more machine-parsable (#398).
• Licensing information has been added to the top-level __init__.py file of the package (#398).
• The README.rst file has been updated to include a table of relevant badges (#398).
• All calls using use_cftime=True have been updated to decode_times=xr.coders.CFDatetimeCoder(use_cftime=True) as suggested by xarray (#398).

CI Changes

• Added a workflow for uploading preview releases to TestPyPI (#374).
• GitHub Workflows now make more use of step-security/harden-runner Action for security hardening (#398).
• Python libraries used for CI are now listed in CI/requirements_ci.in and pinned by their hashes in CI/requirements_ci.txt (#398).
• Coverage reporting now uses the coverallsapp/github-action Action. Conda builds now also report coverage to Coveralls (#398).

v0.15.0

New Features

• The functionality of the roocs-utils library has been folded into clisops. roocs-utils is no longer a dependency of clisops (#368, #370).
• The CONFIG settings have been updated to reflect the changes in roocs-utils and those required in clisops (#370).
• Several development tooling libraries have been updated to their latest versions (#368).

Other Changes

• The pytest testing suite has been updated to reflect the changes in the roocs-utils library and the new clisops configuration settings (#368, #370):
  • Tests previously found in roocs-utils have migrated to clisops.
  • xclim.testing.utils.open_dataset() has been deprecated in favour of xclim.testing.utils.nimbus().fetch().

v0.14.1

New Features

• Added new methods to clisops.core.regrid.Grid
  • Added possibility to apply land or ocean mask if present in the file
  • Adapted method from ESMF to detect smashed cells
  • Masking degenerate (i.e. collapsed and smashed) cells
  • Dropping lat/lon bounds if an integrity check fails
  • Added a few attributes to the Grid object
• clisops.ops.regrid: added option to request a land/sea mask for the output grid
• clisops.utils.dataset_utils
  • Added function determine_lon_lat_range to determine the min. and max. lat and lon values
  • Added function fix_unmasked_missing_values_lon_lat to identify and mask yet unmasked missing values in lat and lon arrays
  • Added force parameter to cf_convert_between_lon_frames

Bug Fixes

• clisops.utils.dataset_utils
  • Fixed issue in cf_convert_between_lon_frames causing the longitude frame to not be adjusted in case of NaNs in the longitude array
  • Addressed issues in generate_bounds_curvilinear
    • latitudes are now clipped above 90 or below -90 degrees north
    • longitudes are converted to longitude frame -180, 180
    • longitude bounds are adjusted at the Greenwich meridian or anti meridian to avoid grid cells wrapping once or more times around the globe
    • Bounds are generated significantly faster due to making use of index slicing and numpy.vectorize

Breaking Changes

• Adapted functions from roocs_utils.xarray_utils.xarray_utils into clisops.utils.dataset_utils
  • get_coord_by_type now returns the name of the coordinate variable and not the coordinate variable
  • get_coord_by_type optionally returns a list with further matches for the coordinate variable
  • get_coord_by_type does no longer raise an exception when more than one coordinate variable matches the requested type
  • get_coord_by_type raises ValueError instead of Exception when the coordinate type is unknown
  • detect_coordinate raises KeyError instead of AttributeError if no coordinate could be detected
  • detect_gridtype raises ValueError for unsupported grid types rather than InvalidParameterValue and Exception
• clisops.core.regrid
  • Grid.detect_coordinate: raises KeyError instead of AttributeError if no coordinate could be detected
• clisops.ops.regrid
  • Regrid._calculate: issues UserWarning instead of letting clisops.core.Weights.__init__ raise an Exception when input and output grid are alike

Other Changes

• The testing suite has been refactored to make better use of context handlers when opening files with xarray, preventing synonymous read errors and improving the overall performance of the tests.
• Several tests that were failing due to significantly long runtimes have been marked as slow and are now skipped by default.
• GitHub Workflows now use a timeout of 20 minutes for the build suite to prevent hanging builds.

v0.14.0

New Features

• clisops now makes use of pytest-xdist for parallel testing. This can be enabled using --numprocesses={int}. See the pytest-xdist documentation <https://pytest-xdist.readthedocs.io/en/latest/>_ for more information (#345).
• Testing data caching is now handled by pooch and testing data registries ('stratus' for roocs/mini-esgf-data and 'nimbus' for Ouranosinc/xclim-testdata) (#345).
• clisops coding conventions now use Python 3.9+ conventions (#345).

Breaking Changes

• netCDF4 has been moved from core dependency to development dependency (#345).

Other Changes

• The _common testing tools have been migrated to clisops.utils.testing or rewritten as pytest fixtures (#345).
• Testing data fetching now uses worker threads to copy cached data to threadsafe data caches that are separated by worker (#345).

v0.13.1

Bug Fixes

• Changed the order of operations in clisops.core.subset.subset_shape to ensure that the CRS of the shapefile is compatible with the dataset CRS before attempting to subset (#340).
