Adds a keyword only flag to zlib.decompress and zlib.Decompress.decompress which marks that the return type should be a bytearray instead of bytes.
The use case for this is reading compressed data into a mutable array to do further operations without requiring that the user copy the data first. Often, if a user is choosing to compress the data there might be a real cost to copying the uncompressed bytes into a mutable buffer.
The impetus for this change comes from a patch for Pandas (https://github.com/pydata/pandas/pull/12359). I have also worked on a similar feature for blosc, another popular compression library for python (https://github.com/Blosc/python-blosc/pull/107).
My hope is to fix the hacky solution presented in the pandas patch by supporting this feature directly in the compression libraries.
As a side note: this is my first time using the argument clinic and I love it. It was so simple to add this argument, thank you very much for developing such an amazing tool! |
