```
The MongoDB C driver (libbson) deprecated bson_as_json() in version
1.29.0 (October 2024) in favor of bson_as_legacy_extended_json() to
clarify which JSON format is being produced (legacy vs. canonical
extended JSON).
We added compatibility macro at the top of cachedb_mongodb_dbase.c - for
mongo-c-driver < 1.29.0, define bson_as_legacy_extended_json as an alias
to bson_as_json, allowing the code to use the new API name while
maintaining backward compatibility.
This change maintains compatibility with all mongo-c-driver versions.
The new function name is used on >= 1.29.0, while older versions
transparently use the original bson_as_json() through the macro alias.
No behavioral changes - the replacement is functionally identical and
produces the same JSON output format. The new name simply makes it
explicit that the legacy extended JSON format is being used.
Note: mongo-c-driver 1.29.0 was released in October 2024. Many LTS
distributions still ship earlier versions (e.g., RHEL 8/9, Ubuntu
20.04/22.04, Debian 11/12), making the compatibility macro necessary.
