Bug#49369: No testcase for key caches on partitions
The original test case was lost when merging WL#4571. Added the testcase. mysql-test/include/check_key_reads.inc: Bug#49369: No testcase for key caches on partitions New include file for testing key caches on partitions WL#4571 mysql-test/include/check_key_req.inc: Bug#49369: No testcase for key caches on partitions New include file for testing key caches on partitions WL#4571 mysql-test/r/partition_key_cache.result: Bug#49369: No testcase for key caches on partitions New test case for testing key caches on partitions WL#4571 mysql-test/t/partition_key_cache.test: Bug#49369: No testcase for key caches on partitions New test case for testing key caches on partitions WL#4571
