    • A failure identification routine uses a two pass stack trace analysis in conjunction with a list of called types. As each method is called, a call list is generated with the called type, method, and various metadata. During the first pass stack trace analysis, each stack frame is analyzed to determine if the failed type is included in the stack frame. If so, the method associated with the frame is flagged as suspect. If the failed type is not found in the first stack trace, a second pass stack trace analysis is performed and an assembly associated with the method associated with the stack frame is analyzed to determine a set of types. The set of types are analyzed to find at least one match with the called types. If a match exists, the methods associated with the matched types are flagged as suspect.
    • 故障识别程序使用两次堆栈跟踪分析与一个被叫类型的列表。 当调用每个方法时,将使用调用类型,方法和各种元数据生成调用列表。 在第一遍堆栈跟踪分析期间,分析每个堆栈帧以确定堆栈帧中是否包括故障类型。 如果是这样,与帧相关联的方法被标记为可疑。 如果在第一个堆栈跟踪中找不到失败的类型,则执行第二遍堆栈跟踪分析,并分析与与堆栈帧相关联的方法相关联的组件以确定一组类型。 分析一组类型以找到与被调用类型至少一个匹配。 如果存在匹配,与匹配类型相关联的方法将被标记为可疑。
