on tables with partitions Problem was that the handler function try_semi_consistent_read was not propagated to the innodb handler. Solution was to implement that function in the partitioning handler. mysql-test/r/partition_innodb.result: Bug#40595: Non-matching rows not released with READ-COMMITTED on tables with partitions Updated test result. mysql-test/t/partition_innodb.test: Bug#40595: Non-matching rows not released with READ-COMMITTED on tables with partitions Added test case for bug#40595. Note: the replace_regex is taking long time. I have not found any better regex (it takes time using 'sed' too). sql/ha_partition.cc: Bug#40595: Non-matching rows not released with READ-COMMITTED on tables with partitions Added function to the partitioning handler for handling semi consistent reads (unlock_row was already implemented, and this is needed for unlock_row to work properly in innodb). It uses pruning for optimizing the call. sql/ha_partition.h: Bug#40595: Non-matching rows not released with READ-COMMITTED on tables with partitions Added function to the partitioning handler for handling semi consistent reads (unlock_row was already implemented, and this is needed for unlock_row to work properly in innodb).
