Release 0.13.0.dev7 · xcube-dev/xcube

Changes in 0.13.0.dev7

xcube Server has been enhanced to load multi-module Python code
for dynamic cubes both from both directories and zip archives.
For example, the following dataset definition computes a dynamic
cube from dataset "local" using function "compute_dataset" in
Python module "resample_in_time.py":
```
  Path: resample_in_time.py
  Function: compute_dataset
  InputDatasets: ["local"]
```
Users can now pack "resample_in_time.py" among any other modules and
packages into a zip archive. Note that the original module name
is now a prefix to the function name:
```
  Path: modules.zip
  Function: resample_in_time:compute_dataset
  InputDatasets: ["local"]
```
Implementation note: this has been achieved by using
xcube.core.byoa.CodeConfig in
xcube.core.mldataset.ComputedMultiLevelDataset.
Instead of the Function keyword it is now
possible to use the Class keyword.
While Function references a function that receives one or
more datasets (type xarray.Dataset) and returns a new one,
Class references a callable that receives one or
more multi-level datasets and returns a new one.
The callable is either a class derived from
or a function that returns an instance of
xcube.core.mldataset.MultiLevelDataset.
Module xcube.core.mldataset has been refactored into
a sub-package for clarity and maintainability.
Provided backward compatibility with Python 3.8. (#760)
