Please change local file path # This is the commit message prestodb#2: Making information schema skippable # This is the commit message prestodb#3: minor improvements # This is the commit message prestodb#4: Fix truncated print for ProjectionNode in PlanPrinter # This is the commit message prestodb#2: Cleanup all temporary files when writing sorted Hive tables # This is the commit message prestodb#3: Prevent nulls fraction to be negative in subtractColumnStats # This is the commit message prestodb#2: Better estimate NDVs and range in subtractColumnStats When there is too little rows per distinct values to be substracted, then both original range and NDVs should be preserved. # This is the commit message prestodb#2: Mark subtractColumnStats as @deprecated as it semantics is undefined # This is the commit message prestodb#3: Dispose resources in WorkProcessorUtils when they are no longer needed # This is the commit message prestodb#4: Add WorkProcessor#transformProcessor method This methods allows to write more streamlined transformations of the processor itself, e.g: processor.transformProcessor(WorkProcessorUtils::flatten) # This is the commit message prestodb#2: Fix error message in QuerySessionSupplier # This is the commit message prestodb#2: Rename singleExpression to standaloneExpression This better reflects the intent of the parsing rule. # This is the commit message prestodb#2: Improve parsing error message The name appears as the prefix of some errors. E.g., xxxxx is too large (stack overflow while parsing) "path specification" reads better than "pathSpec" # This is the commit message prestodb#3: Log raised during error handling It was logging the parsing exception, not the exception that could occur while handling the parsing error due to a bug in the implementation. # This is the commit message prestodb#2: Tighten assertion for parsing failure in TestSqlEnvironmentConfig # This is the commit message prestodb#3: Implement recursion-free ATN simulator The new implementation tracks all the possible states the ATN can be in in a single queue instead of recursing when processing sub-rules. This vastly simplifies the code, makes it easier to reason about and debug. It also fixes a latent bug where some contexts were not being visited, which missed some candidate tokens. # This is the commit message prestodb#4: Raise requried Java version to 8u151 Some test cases failed due to JDK MethodHandle bug in 8u92. These tests passed in 8u151. # This is the commit message prestodb#5: Track origin column for fields This is needed to ensure we only check column access privileges for origin columns. # This is the commit message prestodb#6: Don't check column access for aliases Fixes queries that have column aliases defined in the query like `SELECT col1 AS my_alias FROM table`. Previously, we checked if a user had permission to access "col1" and "my_alias". Now we only check "col1". # This is the commit message prestodb#2: Add wrapped Boolean benchmarks Benchmark Mode Cnt Score Error Units BenchmarkBoxedBoolean.booleanEquals thrpt 30 4596.863 ± 26.817 ops/ms BenchmarkBoxedBoolean.booleanEqualsNotNull thrpt 30 4484.421 ± 43.358 ops/ms BenchmarkBoxedBoolean.identity thrpt 30 4610.811 ± 85.104 ops/ms BenchmarkBoxedBoolean.object thrpt 30 4558.072 ± 68.325 ops/ms BenchmarkBoxedBoolean.primitive thrpt 30 4450.140 ± 52.258 ops/ms BenchmarkBoxedBoolean.unboxing thrpt 30 4506.205 ± 26.116 ops/ms # This is the commit message prestodb#3: Implement equality comparisons projection benchmark Bechmark creates an expression with 100 comparisions concatenated with OR and executes them on a single 1MB page with 10 BIGINT channels.

The code only supportes fixed with columns , and has some hacks to get width information into the operators, but it does generally show the direction.
