Description

Original: Hello, I encountered severe performance problems when using the customized warnings parser plugin with regex. It takes about a minute to parse the 250kb file in the attachment for warnings. Even a simple regex like just "INFO" takes 40 seks for the attached file. A 6 MB log file took about 18 minutes with a slightly more dificult skript. When I tested a log on java with about the same size and similar amount of categorys, it terminated after 2 seconds. Skript: import hudson.plugins.warnings.parser.Warning return new Warning("fileName", 1, "Dynamic Parser", "category" , "normal") Regex: ^([A-Z]+):(\s)*\[(.*)\].*at:\s(\w+\.java)\((\d+)\)(\s)*$
