Martin Atkins d14c149001 copy: DeepCopyValue utility ... Over the years we've gradually removed all use of various third-party reflection-based libraries for deep-copying and projecting data structures from main code, because they proved to be a maintenance nightmare and thus better replaced by direct code that is less fun to write but far clearer to read. However, we've still got a few examples of _test_ code hanging on to these helpers because the tradeoffs for unit tests tend to be different. That's valid, but it's annoying to have to include several large and very general dependencies just to support some tests whose needs are well-known and relatively simple. Therefore this new helper function copy.DeepCopyValue aims to be a more straightforward replacement for mitchellh/copystructure (which also indirectly subsumes mitchellh/reflectwalk) that eschews all of the customizability that those libraries offered and instead focuses narrowly on what our few remaining unit tests need. In particular, this replacement doesn't offer any means for registering helper functions to translate struct types with unexported fields. Those instead just get left set to their zero value in the result. Since our focus is only on unit test code, we can know ahead of time when that limitation is relevant and code around it in the calling test rather than complicating this utility code.		2 years ago
