storage.algos.dir_iterators: Fixes and improvements
Closed
requested to merge generated-differential-D444-source into generated-differential-D444-target
Some fixes and improvements regarding recursive directory iteration implemented in the storage.algos.dir_iterators sub-module.
_empty_dir_hash variable did not have correct type (str instead of bytes) so empty directory test based on hash comparison was always failing
in the step method of DirectoryIterator, no need to push a new frame for an empty directory as this will stop the iteration
add Python iterator protocol support in the DirectoryIterator class in order to easily visit in a recursive way any directory stored in the archive.
add convenient function dir_iterator wrapping the instantiation of the DirectoryIterator class
add tests
Those changes are needed to use client-side iteration in the directory cooker from the vault.
