Summary

A batchSize may be set on a mongoc_cursor_t in two ways.

mongoc_collection_find_with_opts allows setting batchSize through the bson_t opts. It accepts either int32 or int64.

mongoc_cursor_set_batch_size only overwrites the internally set batchSize if it was previously set as an int64.

I expect that mongoc_cursor_set_batch_size should overwrite the batchSize if it was also previously set as an int32.

Attached is a proposed regression test.

How to Reproduce

A regression test is attached.

Proposed Scope

• Have mongoc_cursor_set_batch_size override a batchSize that was set as an int32 option.
