背景

• 每日线上会收集回来很多的崩溃信息，但我们往往关心的是有多少类，及该类崩溃信息对应的系统、硬件分布、崩溃 pv、uv 等情况
• 版本间崩溃对比，top20 问题是否有变动，历史版本崩溃是否被修复，线上版本是否有新增崩溃

分析崩溃

第一步、符号化崩溃日志

第二步、获取单个崩溃日志的各项信息

• 获取崩溃线程，然后对线程信息做处理得出崩溃唯一标识

  # 这块暂时不做容错，默认crash均是完整
  lastExceptionBacktrace = re.search(r"Last Exception Backtrace:(.+?)Thread ", c_content, re.S)
  if lastExceptionBacktrace:
      crash_info["crash_thread_detial"] = lastExceptionBacktrace.group(1).strip()
  else:
      try:
          crash_info["crash_thread_detial"] = re.search(r'Crashed:(.+?)Thread ',c_content ,re.S).group(1).strip()
      except:
          print "no Crashed word:",crashPath
          return None
  

• 获取系统版本
  crash_info["os_version"] = re.search(r"OS Version:(.+)", c_content).group(1).strip()

• 获取设备硬件信息

  • crash_info["hardware"] = re.search(r"Hardware Model:(.+)", c_content).group(1).strip()
  • 一般需要做一个映射关系

INTERNAL_NAME = {
    # iPhone 映射关系
    "iPhone1,1": "iPhone",
    "iPhone1,2": "iPhone 3G",
    "iPhone2,1": "iPhone 3GS",
    "iPhone3,1": "iPhone 4",
    "iPhone3,2": "iPhone 4",
    "iPhone3,3": "iPhone 4",
    "iPhone4,1": "iPhone 4S",
    "iPhone5,1": "iPhone 5",
    "iPhone5,2": "iPhone 5",
    "iPhone5,3": "iPhone 5c",
    "iPhone5,4": "iPhone 5c",
    "iPhone6,1": "iPhone 5s",
    "iPhone6,2": "iPhone 5s",
    "iPhone7,2": "iPhone 6",
    "iPhone7,1": "iPhone 6 Plus", 
    "iPhone8,1": "iPhone 6s", 
    "iPhone8,2": "iPhone 6s Plus", 
    # iPad 映射关系
    "iPad1,1": "iPad",
    "iPad2,1": "iPad 2",
    "iPad2,2": "iPad 2",
    "iPad2,3": "iPad 2",
    "iPad2,4": "iPad 2",
    "iPad3,1": "iPad 3",
    "iPad3,2": "iPad 3",
    "iPad3,3": "iPad 3",
    "iPad3,4": "iPad 4",
    "iPad3,5": "iPad 4",
    "iPad3,6": "iPad 4",
    "iPad4,1": "iPad Air",
    "iPad4,2": "iPad Air",
    "iPad4,3": "iPad Air",
    "iPad5,3": "iPad Air 2",
    "iPad5,4": "iPad Air 2",
    "iPad6,7": "iPad Pro",
    "iPad6,8": "iPad Pro"
}

• 获取 app 版本

crash_info["app_version"] = re.search(r"Version:(.+)", c_content).group(1).strip()

第三步、根据上述获取到的信息做聚类即可
