Updated NIP-09 section to document full implementation including:
- 'e' tags for deleting regular events by event ID
- 'a' tags for deleting addressable events by address format (kind:pubkey:d-identifier)
This reflects the implementation added in commits 3ba3318 and 538fe42 which brought the relay into full NIP-09 compliance.
* Implement NIP-16 parameterized replaceable events
Add support for parameterized replaceable events (kinds 30000-39999) to
properly
handle Nostr marketplace product and stall updates according to NIP-16
specification.
Changes:
- Add is_parameterized_replaceable_event property to NostrEvent
- Implement automatic deletion of previous versions when new
parameterized replaceable event is received
- Add 'd' tag filtering support to NostrFilter for parameterized
replacement logic
- Update SQL query generation to handle 'd' tag joins
Fixes issue where product updates would create duplicate entries instead
of
replacing previous versions, ensuring only the latest version remains
visible.
* Refactor event handling for addressable events
Renamed the property is_parameterized_replaceable_event to is_addressable_event in NostrEvent to align with NIP-01 specifications (previously NIP-16). Updated the client_connection.py to utilize the new property for extracting 'd' tag values for addressable replacement, ensuring proper event handling in the relay system.
* Refactor tag filtering logic in NostrFilter
Updated the tag filtering mechanism to ensure that the filter only fails if the specified tags ('e' and 'p') are not found. This change improves clarity and maintains functionality by allowing for more precise control over event filtering.
* update readme
* Fix addressable event deletion and SQL schema issues
- Fix Pydantic field alias usage for d tag filtering (use #d instead of
d)
- Remove nostrrelay schema prefixes from SQL table references
- Implement subquery approach for DELETE operations with JOINs
- Resolve SQLite DELETE syntax incompatibility with JOIN statements
- Ensure NIP-33 compliance: only delete events with matching d tag
values
