pypff: warnings when using bindings

[woheme-c]

I have changed pypff to the new version "libpff-python 20231205" and suddenly I get various errors in my application. I developed my application with the previous "libpff-python 20211114" ... version.

One error concerns the sub_messages:

OSError: pypff_folder_get_number_of_sub_messages: unable to retrieve number of sub messages. libpff_data_array_read_entries: unable to find data identifier: 656588. libpff_table_read_descriptor_data_list: unable to read data array entries. libpff_table_values_array_get_value_data_by_entry_number: unable to read descriptor: 63 data: 40492198 list. libpff_table_read_values_array: unable to retrieve record entry values data for index: 1. libpff_table_read_7c_values: unable to read values array. libpff_table_read_values: unable to read 7c table values. libpff_table_read: unable to read table values. libpff_item_values_read: unable to read table. libpff_folder_determine_sub_messages: unable to read descriptor identifier: 8590. libpff_folder_get_number_of_sub_messages: unable to determine sub messages.

Another error concerns the attachments:

pypff_message_get_attachments: unable to retrieve number of attachments. libpff_local_descriptors_node_get_entry_data: invalid local descriptors node. libpff_local_descriptors_get_value_by_identifier: unable to retrieve node entry: 0 data. libpff_local_descriptors_tree_get_value_by_identifier: unable to retrieve index value: 1649 from index. libpff_table_get_local_descriptors_value_by_identifier: unable to retrieve local descriptor identifier: 1649. libpff_item_values_get_local_descriptors_value_by_identifier: unable to retrieve local descriptor identifier: 1649. libpff_message_determine_attachments: unable to retrieve local descriptor identifier: 1649. libpff_message_get_number_of_attachments: unable to determine attachments.

Has anyone already found a solution or some information about this errors?

As indicated in #2 Python bindings are work in progress, marking as duplicate

Just to clarify - the python bindings have been WIP since 2014 and could break with any update and therefore should not be used? I ran into the same breaking issue regarding attachments after a updating from 20211114 to 20231205 and nothing indicated that I should expect the bindings to just stop working.

And they will remain that way until I have time to work on it. Or if you need them urgently fixed I recommend hiring someone to fix them for you.

my point is there is nothing indicating for you expect the bindings to be working in the first place

Hiring someone is going to take too long, I can't do a release right now. I can't postpone releases until I find a developer to fix this issue.

Maybe mention it on the docs page? https://github.com/libyal/libpff/wiki/Python-development
I admit I missed the alpha status on the pypi package, that's on me. I'll go find another solution to deal with pst files.
