v1.3.0

Migration

Starting with this release, all subsequent changes will be published officially inside https://github.com/tarantool/go-vshard-router

BUG FIXES:

• Fix decoding fields for StorageCallVShardError (MasterUUID, ReplicasetUUID).

CHANGES:

• Add comment why and how we handle "NON_MASTER" vshard error.
• Don't support 'type Error struct' anymore.
• Linter: don't capitalize error strings and capitalize log.
• Fix misspellings.
• Handle vshard error the same way as lua vshard router (resolve issue #77).
• Decode 'vshard.storage.call' response manually into struct vshardStorageCallResponseProto using DecodeMsgpack interface to reduce allocations (partially #61, #100).
• Remove mapstructure tag from StorageCallVShardError.
• Update benchmarks in README files.
• Package mapstructure is completely removed from direct dependencies list.

FEATURES:

• Add pause between requests in buckets discovering. Configured by config DiscoveryWorkStep, default is 10ms.
• Add ReplicaUUID to the StorageCallVShardError struct.
• New method 'RouterMapCallRW[T]' to replace the deprecated one 'RouterMapCallRWImpl'.
• New method 'Router.Call' to replace the deprecated one 'RouterCallImpl'.

REFACTOR:

• Use constants for vshard error names and codes.
• Reduce SLOC by using CallAsync method.
• BucketForceCreate optimization: don't decode tnt response.
• Remove bucketStatError type, use StorageCallVShardError type instead.
• Add custom msgpackv5 decoder for 'vshard.storage.bucket_stat' response (partially #100).
• Add custom msgpackv5 decoder for 'BucketStatInfo', since msgpackv5 library has an issue (see commit content).
• Add custom msgpackv5 decoder for 'RouterMapCallRW'.
• New backward-compatible signature for StorageResultTypedFunc to fix interface for RouterCallImpl.

TESTS:

• Rename bootstrap_test.go -> tarantool_test.go and new test in this file.
• Test for new 'RouterMapCallRW[T]'.

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

• 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
