v1.2.0

CHANGES:

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).

REFACTOR:

• Func bucketSearchLegacy: log error from bucketStatWait (except bucketStatError).
• New bucketsDiscoveryAsync, bucketsDiscoveryWait, bucketsDiscovery methods for buckets discovery pagination.

TESTS:

• Tests for BucketsSearchMode (tnt/discovery_test.go).

• Legacy integration tests removed (tests/integration).
