|  | 1 # Gardening Tools | 
|  | 2 | 
|  | 3 This directory is created for gathering all tools doing gardening in one place. | 
|  | 4 Every tools or script, big or small should go here, and over time, hopefully | 
|  | 5 we will have useful collection of tools that support every part of the | 
|  | 6 gardening work. | 
|  | 7 | 
|  | 8 The current tools are: | 
|  | 9 | 
|  | 10 #### compare_failures #### | 
|  | 11 Compares the test log of a build step with previous builds. Use this to detect | 
|  | 12 flakiness of failures, especially timeouts. | 
|  | 13 | 
|  | 14 Usage: | 
|  | 15 | 
|  | 16     compare_failures.dart <stdio-url> | 
|  | 17 | 
|  | 18 where `<stdio-url>` is a url for a test log (".../logs/stdio") from the | 
|  | 19 buildbot. |
