v1.2.0

CHANGES:

• We don't support LogProvider interface anymore, only LogfProvider should be used.

BUG FIXES:

• RouterCallImpl: retry on BucketResolve error.
• RouterCallImpl: do not retry on vshard error "TRANSFER_IS_IN_PROGRESS".
• RouterCallImpl: remove misleading RetryOnCall.
• AddInstance bugfix: pass r.cfg.PoolOpts to new instance.

FEATURES:

• Support StdoutLoggerf that allows control log level (resolve issue #84).
• Support new BucketsSearchMode config to set policy for BucketDiscovery (resolve #71).
• Implemented CalculateEtalonBalance based on lua router (part of #32).
• Implement go-tarantool Logger interface to use the same logger as router uses (resolve issue #79).
• Implemented ClusterBootstrap function based on lua router (#32).

REFACTOR:

• Func bucketSearchLegacy: log error from bucketStatWait (except bucketStatError).
• New bucketsDiscoveryAsync, bucketsDiscoveryWait, bucketsDiscovery methods for buckets discovery pagination.
• Support bucketSearchBatched method for batched buckets discovery (resolve #71).

TESTS:

• Tests for BucketsSearchMode (tnt/discovery_test.go).
• The tests have been rewritten in such a way that now you can configure the cluster to suit any needs, the configuration of the clusters may differ and the launch is controlled from go.
• Legacy integration tests removed (tests/integration).

v1.1.0

CHANGES:

• now if there is no etcd connection - etcd provider returns you error instead panic.
• etcd provider also accepts context as input for working with the logger.

BUG FIXES:

• fixed the problem of re-creating a new context when starting discovery, which led to a lack of discovery logging.

TESTS:

• Simplify test/tnt/{Makefile,router.lua).
• Indent fix for test/tnt/storage.lua.

FEATURES:

• now we write topology changes to debug logs.
• now we write info logs about new replicaset adding and nodes state.
• added pull request template to repository.

v1.0.1

BUG FIXES:

• fix invalid go-tarantool backward compatibility: NewCallRequest not method of router.

v1.0.0

This is the first version with which releases are recorded in the changelog and the version is production ready

Changelog

BUG FIXES:

• RouterCallImpl: fix decoding response from storage_ref (partially #42)
• RouterCallImpl: fix decoding response from storage_map (partially #42)
• BucketDiscovery: check res for nil
• BucketStat: decode bsInfo by ptr
• ReplicaCall: fix decoding response (#42)
• ReplicaCall: fix ignoring timeout while waiting for future.Get()
• Fix retry on Client or LuaJit error

FEATURES:

• Support new Sprintf-like logging interface (#48)
• DiscoveryTimeout by default is 1 minute (zero DiscoveryTimeout is not allowed #60)
• All discovering logs has new prefix [DISCOVERY]
• Introduce Replicaset.CallAsync, it is usefull to send concurrent requests to replicasets;
  additionally, CallAsync provides new interface to interact with replicaset without cons of interface of ReplicaCall
• Retry tarantool request only on some vshard errors (#66).
• Added call interfaces backwards compatible with go-tarantool (#31).

REFACTOR:

• resolve issue #38: simplify DiscoveryAllBuckets and remove suspicious if
• resolve issue #46: drastically simplify RouterMapCallRWImpl and added tests with real tnt
• Use typed nil pointers instead of memory allocation for EmptyMetrics and emptyLogger structs
• resolve issue #44: remove bucketCount field from struct Replicaset
• rename startCronDiscovery to cronDiscovery and make it panic-tolerant
• BucketStat: split into bucketStatAsync and bucketStatWait parts
• BucketDiscovery: do not spawn goroutines, just use futures in the single goroutine
• BucketResolve: make it alias for BucketDiscovery
• do not export anymore storageCallAssertError, bucketStatError

TESTS:

• New test for RouterCallImpl (and fix the old one)
• New tnt tests for discovery logic
• New tnt tests for RouterMapCallRWImpl
• New tnt tests for topology logic
• Big CI update
  • 2 sections for CI: static checks and tests
  • integration tests run on ci with Tarantool cluster on vshard
  • implemented luacheck for static checks
• New tnt tests for ReplicaCall
• New tnt tests for CallAsync
• Init Go benches for tests/tnt

EXAMPLES:

• customer go mod fixed
• add customer example listen addr log
