Release 2.0.0

[oleg-jukovec]

Overview

There are a lot of changes in the new major version. The main ones:

• The go_tarantool_call_17 build tag is no longer needed, since by default the CallRequest is Call17Request.
• The go_tarantool_msgpack_v5 build tag is no longer needed, since only the msgpack/v5 library is used.
• The go_tarantool_ssl_disable build tag is no longer needed, since the connector is no longer depends on OpenSSL by default. You could use the external library go-tlsdialer to create a connection with the ssl transport.
• Required Go version is 1.20 now.
• The Connect function became more flexible. It now allows to create a connection with cancellation and a custom Dialer implementation.
• It is required to use Request implementation types with the Connection.Do method instead of Connection.<Request> methods.
• The connection_pool package renamed to pool.

See the migration guide for more details.

Breaking changes

• connection_pool renamed to pool (https://github.com/tarantool/go-tarantool/issues/239).
• Use msgpack/v5 instead of msgpack.v2 (https://github.com/tarantool/go-tarantool/issues/236).
• Call/NewCallRequest = Call17/NewCall17Request (https://github.com/tarantool/go-tarantool/issues/235).
• Change encoding of the queue.Identify() UUID argument from binary blob to plain string. Needed for upgrade to Tarantool 3.0, where a binary blob is decoded to a varbinary object (https://github.com/tarantool/go-tarantool/pull/313).
• Use objects of the Decimal type instead of pointers (https://github.com/tarantool/go-tarantool/issues/238).
• Use objects of the Datetime type instead of pointers (https://github.com/tarantool/go-tarantool/issues/238).
• connection.Connect no longer return non-working connection objects (https://github.com/tarantool/go-tarantool/issues/136). This function now does not attempt to reconnect and tries to establish a connection only once. Function might be canceled via context. Context accepted as first argument. pool.Connect and pool.Add now accept context as the first argument, which user may cancel in process. If pool.Connect is canceled in progress, an error will be returned. All created connections will be closed.
• iproto.Feature type now used instead of ProtocolFeature (https://github.com/tarantool/go-tarantool/issues/337).
• iproto.IPROTO_FEATURE_ constants now used instead of local Feature constants for protocol (https://github.com/tarantool/go-tarantool/issues/337).
• Change crud operations Timeout option type to crud.OptFloat64 instead of crud.OptUint (https://github.com/tarantool/go-tarantool/issues/342).
• Change all Upsert and Update requests to accept *tarantool.Operations as ops parameters instead of interface{} (https://github.com/tarantool/go-tarantool/issues/348).
• Change OverrideSchema(*Schema) to SetSchema(Schema) (https://github.com/tarantool/go-tarantool/issues/7).
• Change values, stored by pointers in the Schema, Space, Index structs, to be stored by their values (https://github.com/tarantool/go-tarantool/issues/7).
• Make Dialer mandatory for creation a single connection (https://github.com/tarantool/go-tarantool/issues/321).
• Remove Connection.RemoteAddr(), Connection.LocalAddr(). Add Addr() function instead (https://github.com/tarantool/go-tarantool/issues/321).
• Remove Connection.ClientProtocolInfo, Connection.ServerProtocolInfo. Add ProtocolInfo() function instead, which returns the server protocol info (https://github.com/tarantool/go-tarantool/issues/321).
• NewWatcher checks the actual features of the server, rather than relying on the features provided by the user during connection creation (https://github.com/tarantool/go-tarantool/issues/321).
• pool.NewWatcher does not create watchers for connections that do not support it (https://github.com/tarantool/go-tarantool/issues/321).
• Rename pool.GetPoolInfo to pool.GetInfo. Change return type to map[string]ConnectionInfo (https://github.com/tarantool/go-tarantool/issues/321).
• Response is now an interface (https://github.com/tarantool/go-tarantool/issues/237).
• All responses are now implementations of the Response interface (https://github.com/tarantool/go-tarantool/issues/237). SelectResponse, ExecuteResponse, PrepareResponse, PushResponse are part of a public API. Pos(), MetaData(), SQLInfo() methods created for them to get specific info. Special types of responses are used with special requests.
• IsPush() method is added to the response iterator (https://github.com/tarantool/go-tarantool/issues/237). It returns the information if the current response is a PushResponse. PushCode constant is removed.
• Method Get for Future now returns response data (https://github.com/tarantool/go-tarantool/issues/237). To get the actual response new GetResponse method has been added. Methods AppendPush and SetResponse accept response Header and data as their arguments.
• Future constructors now accept Request as their argument (https://github.com/tarantool/go-tarantool/issues/237).
• Operations Ping, Select, Insert, Replace, Delete, Update, Upsert, Call, Call16, Call17, Eval, Execute of a Connector and Pooler return response data instead of an actual responses (https://github.com/tarantool/go-tarantool/issues/237).
• pool.Connect, pool.ConnetcWithOpts and pool.Add use a new type pool.Instance to determinate connection options (https://github.com/tarantool/go-tarantool/issues/356).
• pool.Connect, pool.ConnectWithOpts and pool.Add add connections to the pool even it is unable to connect to it (https://github.com/tarantool/go-tarantool/issues/372).
• Required Go version from 1.13 to 1.20 (https://github.com/tarantool/go-tarantool/issues/378).

Overall, imports should look like this:
