据 Google 宣称，Flogger 可“比现有的日志 API 提供更多的优点”。其中包括：降低了禁用日志语句的代价、增加了总体的可读性，以及对可扩展性的支持。

\n

Flogger 宣称其主要优点之一是“对于已禁用日志层级的完全无代价实现”，而其他所有日志记录框架依然可能会对已禁用的日志语句生成字节码。Flogger 在设计上考虑了完全避免产生额外的代价。

\n

示例:

\n
logger.atError()\n  .withCause(exception)\n  .log("The arg, ‘%s’ caused an error", arg);
\n

疑问：如果这样写

\n
logger.at(DEBUG)\n  .log("The request is ‘%s’ caused an error", JSON.toString(request));

也还是无解的吧？

更多私密信息处理办法见6.3 把机密信息从配置文件中抽离出来，或者使用包对其加密

\n
\n

不要在配置文件或源代码中存储纯文本机密信息。相反, 使用诸如Vault产品、Kubernetes/Docker Secrets或使用环境变量之类的安全管理系统。最后一个结果是, 存储在源代码管理中的机密信息必须进行加密和管理 (滚动密钥(rolling keys)、过期时间、审核等)。使用pre-commit/push钩子防止意外提交机密信息。

Asyncio 和 async/await

\n

async/await成为了保留关键字。同时简化了Asyncio的使用。

\n

3.7之前：

\n
import asyncio\nloop = asyncio.get_event_loop()\nloop.run_until_complete(some_async_task())\nloop.close()
\n

3.7之后：

\n
import asyncio\nasyncio.run(some_async_task())
\n

新关键字breakpoint()

\n
do_something()\nbreakpoint() #进入调试\ndo_something_else()
\n

上下文变量

\n
import contextvars\nimport asyncio\n\nval = contextvars.ContextVar(\"val\", default=\"0\")\n\nasync def setval():\n   val.set(\"1\") #独立的val，设置的值不会影响其他上下文\n\nasync def printval():\n   print(val.get()) #独立的val，取得是默认值\n\nasyncio.run(setval()) # 1\nasyncio.run(printval()) # 0

Dictionaries 默认就是保持顺序的

\n

3.7后默认的字典就是保持顺序的，OrderedDict依然未变。
