v2.0.0
Overview
There are many changes in the new major version. The main ones:
- The
go_tarantool_call_17
build tag is no longer needed, since by default theCallRequest
isCall17Request
. - The
go_tarantool_msgpack_v5
build tag is no longer needed, since only themsgpack/v5
library is used. - The
go_tarantool_ssl_disable
build tag is no longer needed, since the connector is no longer depends onOpenSSL
by default. You could use the external library go-tlsdialer to create a connection with thessl
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 customDialer
implementation. - It is required to use
Request
implementation types with theConnection.Do
method instead ofConnection.<Request>
methods. - The
connection_pool
package renamed topool
.
See the migration guide for more details.
Breaking changes
- connection_pool renamed to pool (#239).
- Use msgpack/v5 instead of msgpack.v2 (#236).
- Call/NewCallRequest = Call17/NewCall17Request (#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 (#313).
- Use objects of the Decimal type instead of pointers (#238).
- Use objects of the Datetime type instead of pointers (#238).
connection.Connect
no longer return non-working connection objects (#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
andpool.Add
now accept context as the first argument, which user may cancel in process. Ifpool.Connect
is canceled in progress, an error will be returned. All created connections will be closed.iproto.Feature
type now used instead ofProtocolFeature
(#337).iproto.IPROTO_FEATURE_
constants now used instead of localFeature
constants forprotocol
(#337).- Change
crud
operationsTimeout
option type tocrud.OptFloat64
instead ofcrud.OptUint
(#342). - Change all
Upsert
andUpdate
requests to accept*tarantool.Operations
asops
parameters instead ofinterface{}
(#348). - Change
OverrideSchema(*Schema)
toSetSchema(Schema)
(#7). - Change values, stored by pointers in the
Schema
,Space
,Index
structs, to be stored by their values (#7). - Make
Dialer
mandatory for creation a single connection (#321). - Remove
Connection.RemoteAddr()
,Connection.LocalAddr()
. AddAddr()
function instead (#321). - Remove
Connection.ClientProtocolInfo
,Connection.ServerProtocolInfo
. AddProtocolInfo()
function instead, which returns the server protocol info (#321). NewWatcher
checks the actual features of the server, rather than relying on the features provided by the user during connection creation (#321).pool.NewWatcher
does not create watchers for connections that do not support it (#321).- Rename
pool.GetPoolInfo
topool.GetInfo
. Change return type tomap[string]ConnectionInfo
(#321). Response
is now an interface (#237).- All responses are now implementations of the
Response
interface (#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 (#237). It returns the information if the current response is aPushResponse
.PushCode
constant is removed.- Method
Get
forFuture
now returns response data (#237). To get the actual response newGetResponse
method has been added. MethodsAppendPush
andSetResponse
accept responseHeader
and data as their arguments. Future
constructors now acceptRequest
as their argument (#237).- Operations
Ping
,Select
,Insert
,Replace
,Delete
,Update
,Upsert
,Call
,Call16
,Call17
,Eval
,Execute
of aConnector
andPooler
return response data instead of an actual responses (#237). pool.Connect
,pool.ConnetcWithOpts
andpool.Add
use a new typepool.Instance
to determinate connection options (#356).pool.Connect
,pool.ConnectWithOpts
andpool.Add
add connections to the pool even it is unable to connect to it (#372).- Required Go version from
1.13

field from theConnection
struct is removed (#7).OkCode
andPushCode
constants are removed (#237).- SSL support is removed (#301).
Future.Err()
method is removed (#382).
New features
- Type() method to the Request interface (#158).
- Enumeration types for RLimitAction/iterators (#158).
- IsNullable flag for Field (#302).
- Meaningful description for read/write socket errors (#129).
- Support
operation_data
incrud.Error
(#330). - Support
fetch_latest_metadata

noreturn
option for data change crud requests (#335). - Support
crud.schema

IPROTO_WATCH_ONCE
request type for Tarantool version >= 3.0.0-alpha1 (#337). - Support
yield_every
option for crud select requests (#350). - Support
IPROTO_FEATURE_SPACE_AND_INDEX_NAMES
for Tarantool version >= 3.0.0-alpha1 (#338). It allows to use space and index names in requests instead of their IDs. GetSchema
function to get the actual schema (#7).- Support connection via an existing socket fd (#321).
Header
struct for the response header (#237). It can be accessed viaHeader()
method of theResponse
interface.Response
method added to theRequest
interface (#237).- New
LogAppendPushFailed
connection log constant (#237). It is logged when connection fails to append a push response. ErrorNo
constant that indicates that no error has occurred while getting the response (#237).AuthDialer
type for creating a dialer with authentication (#301).ProtocolDialer
type for creating a dialer withProtocolInfo
receiving and check (#301).GreetingDialer

value is negative (#314). - Incorrect options (
after
,batch_size
andforce_map_call
) setup for crud.SelectRequest (#320). - Incorrect options (
vshard_router
,fields
,bucket_id
,mode
,prefer_replica
,balance
) setup for crud.GetRequest (#335). - Splice update operation accepts 3 arguments instead of 5 (#348).
- Unable to use a slice of custom types as a slice of tuples or objects for
crud.*ManyRequest/crud.*ObjectManyRequest
(#365).
Testing
- More linters on CI (#310).

MockDoer
,MockRequest
totest_helpers

- Fixed tests with crud 1.4.0 (#336).
- Fixed tests with case sensitive SQL (#341).
- Renamed
StrangerResponse
toMockResponse
(#237).
Other
- All Connection., Connection.Typed and Connection.Async methods are now deprecated. Instead you should use requests objects + Connection.Do() (#241).
- All ConnectionPool., ConnectionPool.Typed and ConnectionPool.Async methods are now deprecated. Instead you should use requests objects + ConnectionPool.Do() (#241).
- box.session.push() usage is deprecated: Future.AppendPush() and Future.GetIterator() methods, ResponseIterator and TimeoutResponseIterator types (#324).
