Pull Request Overview

This PR simplifies the BlockStore interface by adding helper methods and improving error handling, making the code more maintainable and consistent. The changes eliminate direct access to internal database wrapper methods and provide cleaner abstractions.

• Adds transaction() and get_block_from_cache() helper methods to BlockStore
• Replaces database version checks with exception-based error handling using UnsupportedDatabaseVersionError
• Improves batch processing in get_block_records_by_hash() to respect database parameter limits

nice.

chia/full_node/block_store.py (93.3%): Missing lines 482

[arvidn]

the one line missed by test coverage is the small change you made:

        if self.db_wrapper.db_version != 2:
            raise RuntimeError("get_block_bytes_in_range requires DB version 2")

This used to be an assert, which suggests that this is checked earlier already

we get_block_records_at for weight proof creation to get all sub epoch summary blocks, the current number of ses blocks should be something like 19283 so this would break when creating weight proofs on mainnet

false alarm
