Processing Server: expand_page_ids is overly strict #1333
Description
I have a workspace with heterogeneous page identifiers:
- f_1875-Himnos-EMU-0040
- f_1878-Helpin-EMU-0027
- f_1890-Evange-UMI-0007
- f_1892-Womans-EMU-0015
- f_192x-Gospel-MTS-0007
When I try to process this in the Processing Server, it fails, because it cannot convert this to a single numerical range:
File "/build/core/src/ocrd_network/processing_server.py", line 744, in run_workflow
responses = await self.task_sequence_to_processing_jobs(
File "/build/core/src/ocrd_network/processing_server.py", line 693, in task_sequence_to_processing_jobs
response = await self.validate_and_forward_job_to_network_agent(
File "/build/core/src/ocrd_network/processing_server.py", line 431, in validate_and_forward_job_to_network_agent
page_ids = expand_page_ids(data.page_id)
File "/build/core/src/ocrd_network/utils.py", line 59, in expand_page_ids
page_ids += generate_range(*page_id_token.split(sep='..', maxsplit=1))
File "/build/core/src/ocrd_utils/str.py", line 231, in generate_range
raise ValueError(f"Range '{start}..{end}' differ in their non-numeric part: '{start[:-len(start_num)]}' != '{end[:-len(end_num)]}'")
ValueError: Range 'f_1875-Himnos-EMU-0040..f_192x-Gospel-MTS-0007' differ in their non-numeric part: 'f_1875-Himnos-EMU-' != 'f_192x-Gospel-MTS-'
This is with page_wise=False.
IMO if splitting is necessary, it should be across integer ranges (pure ordinal page numbers), ignoring page IDs.
