我正在为一个大型自定义 Puppet 模块存储库进行重构项目。这包括从 Puppet 2.x 升级到 3.2.4。当我最终达到临界质量并开始测试一些更改时，我很快遇到了以下错误：
Info: Retrieving plugin
Info: Loading facts in /etc/puppet/modules/base/lib/facter/elversion.rb
Info: Loading facts in /etc/puppet/modules/base/lib/facter/site.rb
Info: Loading facts in /var/lib/puppet/lib/facter/elversion.rb
Info: Loading facts in /var/lib/puppet/lib/facter/site.rb
Error: Could not retrieve catalog from remote server: Error 400 on SERVER: stack level too deep at /etc/puppet/manifests/nodes.pp:9 on node puppet
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run
在查看了各种 Puppet 错误报告后，我决定尝试简化问题。我将问题缩小到两类，定义如下：
class base::includes { }
和
class prod_secure::base::includes inherits base::includes { }
仅包含 prod_secure::base::includes 的节点会产生上面列出的错误输出。我看到的唯一可能相关的警告puppet-lint是：
WARNING: class inherits across module namespaces on line 1
...但这只是警告，我认为不应该在代理运行时导致 Puppet 崩溃。有什么想法吗？我设置的命名空间方案是否可能不受 Puppet 支持？
更新
我决定进一步测试，并更改继承类的名称。新定义是：
class prod_secure::base2::includes2 inherits base::includes { }
结果是一样的……stack level too deep在我看来，这个问题与命名空间无关。

在上一轮调试中我错过了一个显著的细节：

Wrapped exception:
stack level too deep
我不能确定为什么，但它仍在尝试加载 prod_secure::base::includes，而这就是有问题的条目。完全删除该文件后，测试通过了。我又回到了命名空间理论……
答案1
您可能想尝试一下 puppet 3.2.3。
3.2.2 有#21376类似的问题，但它在 3.2.3 中已修复，可能是回归问题
