调用 fail() 失败

Question

我正在尝试设置一个新的 puppetmaster (v5.0.1)，一切顺利，除了一件事。

我无法在清单中调用fail()。当它试图运行任何fail() 函数时，它会抛出一个评估错误。

这发生在 manifests 和 puppet apply 中。

$ puppet apply -e 'fail("Failure")' --trace

将返回以下错误和跟踪：

我确定是我，但我不知道是什么原因造成的。

Answer 1

fail() 函数按设计工作，但错误消息令人困惑。

fail() 函数只是 raise Puppet::ParseError 的包装。通常，Puppet::ParseError 会在 Puppet 函数不做它应该做的事情时引发。在这种情况下，Error while evaluating a Function Call 的消息是有意义的。

然而，这里引发了错误，因为函数正在执行它应该应该做的事情 - 为您引发错误。因此，这不是“评估函数调用时出错”。

不过一直都是这样。
