New Features

Bugs Fixed

  • Fix fetch sub-query aggregation null pointer

    We fix a bug where a Fetch query with a Get-Aggregate subquery that returned an empty (ie. undefined) answer throw a null pointer exception.

    For example this used to incorrectly throw an exception if 'Alice' doesn't have any salaries in the database, since a 'sum' is undefined for 0 entries.

    match
$x isa person, has name $n; $n == "Alice";
fetch
$n as "name";
total-salary: {
  match $x has salary $s;
  get $s; 
  sum $s;
};

    We now correctly return the following JSON structure

    [
  {
    "name": {"value": "Alice",  "type":  {"label": "name", "root": "attribute", "value_type": "string"}},
    "total-salary": null
  }
]

  • Update to tonic 1.28

    We fix a bug in the installation of the latest typedb-driver Rust by upgrading tonic to version 1.28.

Code Refactors

  • Release with Ubuntu 18.04 in to lower GLIBC requirement to 2.27.0

    We downgrade from Ubuntu 20.04 to 18.04 in CircleCI assembly and deployment jobs, using a Docker image. This lowers the minimum supported glibc version from 2.31 to 2.27.

  • Rename typedb.hpp to typedb_driver.hpp

Other Improvements

  • C++ driver documentation and add missing APIs
    Documents the C++ code & adds ascii docs generated via doxygen. Adds a few methods to the classes which were missing.

  • Update python credential documentation

  • Update C and CPP entry in README.md

  • Update C++ readme with new 'cloud' terminology
