Enhancements

Features

• Add (but do not install) a new post-partitioning decorator to handle metadata added for all file-types, like .filename, .filetype and .languages. This will be installed in a closely following PR to replace the four currently being used for this purpose.

Fixes

• Update Python SDK usage in partition_via_api. Make a minor syntax change to ensure forward compatibility with the upcoming 0.26.0 Python SDK.
• Remove "unused" date_from_file_object parameter. As part of simplifying partitioning parameter set, remove date_from_file_object parameter. A file object does not have a last-modified date attribute so can never give a useful value. When a file-object is used as the document source (such as in Unstructured API) the last-modified date must come from the metadata_last_modified argument.
• Fix occasional KeyError when mapping parent ids to hash ids. Occasionally the input elements into assign_and_map_hash_ids can contain duplicated element instances, which lead to error when mapping parent id.
• Allow empty text files. Fixes an issue where text files with only white space would fail to be partitioned.
• Remove double-decoration for CSV, DOC, ODT partitioners. Refactor these partitioners to use the new @apply_metadata() decorator and only decorate the principal partitioner (CSV and DOCX in this case); remove decoration from delegating partitioners.
• Remove double-decoration for PPTX, TSV, XLSX, and XML partitioners. Refactor these partitioners to use the new @apply_metadata() decorator and only decorate the principal partitioner; remove decoration from delegating partitioners.
• Remove double-decoration for HTML, EPUB, MD, ORG, RST, and RTF partitioners. Refactor these partitioners to use the new @apply_metadata() decorator and only decorate the principal partitioner (HTML in this case); remove decoration from delegating partitioners.
• Remove obsolete min_partition/max_partition args from TXT and EML. The legacy min_partition and max_partition parameters were an initial rough implementation of chunking but now interfere with chunking and are unused. Remove those parameters from partition_text() and partition_email().
• Remove double-decoration on EML and MSG. Refactor these partitioners to rely on the new @apply_metadata() decorator operating on partitioners they delegate to (TXT, HTML, and all others for attachments) and remove direct decoration from EML and MSG.
• Remove double-decoration for PPT. Remove decorators from the delegating PPT partitioner.
• Quick-fix CI error in auto test-filetype. Better fix to follow shortly.
