Release v2.3.2 This release improves the logic of `Connect` and `pool.Connect` in case of a hung I/O connection. Changed - Previously, `pool.Connect` attempted to establish a connection one after another instance. It could cause the entire chain to hang if one connection hanged. Now connections are established in parallel. After the first successful connection, the remaining connections wait with a timeout of `pool.Opts.CheckTimeout` (#444). Fixed - Connect() may not cancel Dial() call on context expiration if network connection hangs (#443). - pool.Connect() failed to connect to any instance if a first instance connection hangs (#444).
Release v2.3.1 The patch releases fixes expected Connect() behavior and reduces allocations. Added - A usage of sync.Pool of msgpack.Decoder saves 2 object allocations per a response decoding (#440). Changed - Connect() now retry the connection if a failure occurs and opts.Reconnect > 0. The number of attempts is equal to opts.MaxReconnects or unlimited if opts.MaxReconnects == 0. Connect() blocks until a connection is established, the context is cancelled, or the number of attempts is exhausted (#436).
Release v2.3.0 The release extends box.info responses and ConnectionPool.GetInfo return data. Be careful, we have changed the test_helpers package a little since we do not provide backward compatibility for it. Added - Extend box with replication information (#427). - The Instance info has been added to ConnectionInfo for ConnectionPool.GetInfo response (#429). - Added helpers to run Tarantool config storage (#431). Changed - Changed helpers API `StartTarantool` and `StopTarantool`, now it uses pointer on `TarantoolInstance`: * `StartTarantool()` returns `*TarantoolInstance`; * `StopTarantool()` and `StopTarantoolWithCleanup()` accepts `*TarantoolInstance` as arguments. - Field `Cmd` in `TarantoolInstance` struct declared as deprecated. Suggested `Wait()`, `Stop()` and `Signal()` methods as safer to use instead of direct `Cmd.Process` access (#431). Fixed - Test helpers does not detect a fail to start a Tarantool instance if another Tarantool instance already listens a port (#431).
Release v2.2.0 The release introduces the IPROTO_INSERT_ARROW request (arrow.InsertRequest) and a request to archive `box.info` values (box.InfoRequest). Additionally, it includes some improvements to logging. Added - Error logging to `ConnectionPool.Add()` in case, when unable to establish connection and ctx is not canceled (#389). - Error logging for error case of `ConnectionPool.tryConnect()` calls in `ConnectionPool.controller()` and `ConnectionPool.reconnect()` (#389). - Methods that are implemented but not included in the pooler interface (#395). - Implemented stringer methods for pool.Role (#405). - Support the IPROTO_INSERT_ARROW request (#399). - A simple implementation of using the box interface (#410). Changed - More informative request canceling: log the probable reason for unexpected request ID and add request ID info to context done error message (#407).
Release v2.1.0
Overview
The small release improves the ConnectionPool. The ConnectionPool
is no longer required execute access for `box.info` from a user
for Tarantool >= 3.0.0.
Breaking changes
There are no breaking changes in the release.
New features
`execute` access for `box.info` is no longer required for
ConnectionPool for a Tarantool version >= 3.0.0 (#380).
Bugfixes
`ConnectionPool.Remove()` does not notify a `ConnectionHandler`
after an instance is already removed from the pool (#385).
Release 2.0.0
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[1] 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[2] 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` 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` (#337).
`iproto.IPROTO_FEATURE_` constants now used instead of local
`Feature` constants for `protocol` (#337).
Change `crud` operations `Timeout` option type to `crud.OptFloat64`
instead of `crud.OptUint` (#342).
Change all `Upsert` and `Update` requests to accept
`*tarantool.Operations` as `ops` parameters instead of
`interface{}` (#348).
Change `OverrideSchema(*Schema)` to `SetSchema(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()`.
Add `Addr()` function instead (#321).
Remove `Connection.ClientProtocolInfo`,
`Connection.ServerProtocolInfo`. Add `ProtocolInfo()` 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` to `pool.GetInfo`. Change return type to
`map[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 a
`PushResponse`. `PushCode` constant is removed.
Method `Get` for `Future` now returns response data (#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
(#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 (#237).
`pool.Connect`, `pool.ConnetcWithOpts` and `pool.Add` use a
new type `pool.Instance` to determinate connection options (#356).
`pool.Connect`, `pool.ConnectWithOpts` and `pool.Add` add
connections to the pool even it is unable to connect to it (#372).
