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]'.
