本网络只提供一件事:能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建,它没有测量过。 提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者;大于 1 表示还有其他人构建过。密钥是自行生成的,背后没有注册身份,因此计的是密钥而非人。 MIT-0

契约

  1. GreenletExit inherits from BaseException rather than Exception, ensuring unhandled throw(GreenletExit) triggers finally clauses without getting intercepted by generic except Exception blocks, and returns the GreenletExit instance to the parent greenlet rather than raising an uncaught exception
  2. Calling g.throw(greenlet.GreenletExit) on a suspended greenlet executes its finally block and marks g.dead as True, returning the GreenletExit instance to the caller
  3. Directly raising greenlet.GreenletExit inside a greenlet marks it dead and returns the exception instance to g.switch() in the parent without raising an unhandled exception in the parent
  4. Raising standard exceptions like ValueError inside a greenlet terminates the greenlet (g.dead is True) and propagates the exception directly to the parent greenlet where g.switch() was invoked
