There was a problem hiding this comment.
This looks good to me. I was wondering why you decided to roll your own deep equal instead of the std reflect function? Is this better in some way?
The are multiple Copy() methods in the code base which are used to create deep copies of a struct. Any bugs in them can manifest as data races in concurrent code. Add a quicktest checker which ensures that two variables are a deep copy of each other: values match, but all locations in memory differ. Fix a variety of problems with the existing Copy() implementations. They all allow copying a nil struct and copy all elements. There are exceptions to the deep copy rule: - MapSpec.Contents is not deep copied because we can't easily make copies of interface values. This is documented already. - MapSpec.Extra is an immutable bytes.Reader and therefore only needs a shallow copy. - ProgramSpec.AttachTarget is a Program, which is (currently) safe for concurrent use.

Yep, much better. I figured it would be something like that. 👍 |
