Here are important changes in this release:

  • [httpd] Updated bundled nginx to 1.17.9.

    • For example, we can write load.json instead of load?output_type=json.
  • log Outputted a path of opened or closed file into a log of dump level on Linux.

    • As the fllowing log is outputted.

      [io][open] file_path
      [io][close] file_path
  • log Outputted a path of closed file into a log of debug level on Windows.

    • As the fllowing log is outputted.

      [io][open] file_path
      [io][close] file_path
  • Added following API and macros

    • grn_timeval_from_double(grn_ctx, double)

      • This API converts double type to grn_timeval type.
      • It returns value of grn_timeval type.
    • GRN_TIMEVAL_TO_NSEC(timeval)

      • This macro converts value of grn_timeval type to nanosecond as the value of uint64_t type.
    • GRN_TIME_USEC_TO_SEC(usec)

      • This macro converts microsecond to second.
  • Deprecated the following macro.

    • GRN_OBJ_FORMAT_FIN(grn_ctx, grn_obj_format)

      • We grn_obj_format_fin(grn_ctx, grn_obj_format) use instead since 10.0.0.
  • logical_range_filter, dump Added support for stream output.

    • This feature requires command_version 3 or later. The header content is outputted after the body content.
    • Currently, this feature support only dump and logical_range_filter.
    • logical_range_filter always returns the output as a stream on command_version 3 or later.
    • This feature has the following limitations.

      • -1 is only allowed for negative limit
      • MessagePack output isn't supported
    • We a little changed the response contents of JSON by this modify.

      • The key order differs from before versions as below.
      • If we have processes depend on the order of key, have to be careful.

        • The key order in before versions.

            "header": {...},
            "body": {...}
        • The key order in this version(10.0.0).

            "body": {...},
            "header": {...}
    • Disabled caches of dump and logical_range_filter when they execute on command_version 3.

      • Because of dump and logical_range_filter on command_version 3 returns stream since 10.0.0, Groonga can not cache the whole response.
  • logical_range_filter Added support for outputting response as Apache Arrow format.
