1.0 Alpha 3​

This changelog summarizes new features and breaking changes in EdgeDB 1.0 alpha 3 “Proxima Centauri”.

CLI​

The EdgeDB command-line tools are now written in Rust. The tools are a single binary now and can run on multiple different platforms, including Windows.

A few more commands have been added to REPL:

\dump FILENAME           dump current database into a file
\restore FILENAME        restore the database from file into
                         the current one
\s, \history             show history
\e, \edit [N]            spawn $EDITOR to edit history entry N
                         then use the output as the input
\set [OPTION [VALUE]]    show/change setting
\set                     Show setting descriptions (without
                         arguments)

Existing introspection commands have been slightly updated to use a different way of supplying command options. Commands now also have long-form names that are more human-readable.

Also, there are a few settings that control the look and feel of the REPL (and can be changed via the \set command:

expand-strings             Stop escaping newlines in quoted
                           strings
implicit-properties        Print implicit properties of objects:
                           id, type id
input-mode                 Set input mode. One of: vi, emacs
introspect-types           Print type names instead of `Object`
                           in default output mode (may fail if
                           schema is updated after enabling
                           option)
limit                      Set implicit LIMIT. Defaults to 100,
                           specify 0 to disable
output-mode                Set output mode. One of: json, json-
                           elements, default, tab-separated
verbose-errors             Print all errors with maximum
                           verbosity

EdgeQL​

• Add += and -= operations for use in update (#165).

• Distinguish required and optional query parameters (#1352, #1355)

• Allow tuple arrays in schema definitions (73125882).

• Get rid of schema::CompoundType in favor of is_compound_type property (c30c1c4f).

• Add anytype and anytuple as proper abstract types to the schema (affb65de).

• schema::Constraint no longer has args, use params instead (14cec6f1).

• Make std::Object the implicit base type for all user-defined object types only.

• Make std::BaseObject the root type for all object types both user-defined and system object types.

• Accept 1e100n format as a valid bigint constant rather than decimal (#1372)

• Make self-referencing (recursive) aliases forbidden.

• Fix dependency tracking affecting index creation (#1181).

• Fix derivation of link targets in certain cases of multiple inheritance (52c6b2d4).

• Fix handling of ad-hoc tuples (#1255).

• Fix incorrect implicit limit injection in subqueries in computed expressions (#1271).

• Computables cardinality must now be declared explicitly as required, single or multi. The expression is validated to be within the upper and lower limits implied by the declaration (#1201, #349).

• Prohibit database names longer than 63 characters (#1158).

• Prohibit duplicate elements in shapes (#1368).

• Implement alter function (#1433).

GraphQL​

• Reflect “description” annotations into GraphQL descriptions (#1228).

• Change the auto-generated type name template to use “_Type” suffix (#1175).

• Fix incorrect reflection of enums (#1227).

• Fix deeply nested insert issue (#1243).

Standard Library​

• Add sys::get_current_database()

• Rename std::to_str() array-joining function to array_join().

• Rename std::to_array() string-splitting function to str_split().

Server​

• Convert EdgeQL lexer (#1178)

• Convert GraphQL parser to Rust and perform constant extraction (#1299).

• Constant extraction from EdgeQL queries (#1356)

• Make it possible to use different EdgeDB servers connected to the same Postgres cluster (#1197).

• Protocol: implement JSON_ELEMENTS IO format for responses (#1169).

Misc​

• Add cheatsheet to documentation.

• Strictly type-annotate the core schema module.

• Clean-up and improve schema and introspection code to make the internal APIs more consistent (#1408).

• Update the edgedb-js driver to v0.7.3.

• Update the edgedb-python driver to v0.8.0.
