lilbson 1.30.0

Improvements:

• Improve performance of BSON-to-JSON serialization for nested documents.

Fixes:

• Truncated output of bson_as_json_with_opts is changed to no longer split valid UTF-8 sequences.
• Changes were made to the generated JSON text in some cases:
  • Previously, empty arrays and documents would serialize with either one or two spaces depending on whether it is nested. Empty arrays and documents now consistently serialize with just one space.
  • Previously, an array omitted due to the maximum recursion limit would serialize to "{ ... }", as if it were a document. Omitted arrays now serialize to "[ ... ]".
  • The maximum recursion limit now applies to legacy codewscope documents. Deeply nested scope documents will now be omitted like any other deeply nested document.
• Fix leak of output parameter on failed call to bson_append_array_builder_begin.

New Features:

• Add support for structured logging.
  • See mongoc_client_set_structured_log_opts and mongoc_client_pool_set_structured_log_opts.

  • See mongoc_bulkwrite_new and mongoc_bulkwrite_set_client.

Improvements:

• Improve performance of mongoc_server_description_new_copy.

Fixes:

• Additional APM events required by the SDAM specification will now be delivered:
  • Servers that have seen server_opening will now see a server_closed prior to topology_closed.
  • Before topology_closed, a topology_changed event will transition to Unknown topology type.
• Fix reporting insert IDs in mongoc_bulkwrite_t when verbose results requested.
