James Bardin	b5de50c0a2	don't modify argument slices There were a couple spots where argument slices weren't being copied before `append` was called, which could possibly modify the caller's slice data.	7 years ago
James McGill	035d56409f	helper/schema: handle TypeMap elem consistently with other collection types For historical reasons, the handling of element types for maps is inconsistent with other collection types. Here we begin a multi-step process to make it consistent, starting by supporting both the "consistent" form of using a schema.Schema and an existing erroneous form of using a schema.Type directly. In subsequent commits we will phase out the erroneous form and require the schema.Schema approach, the same as we do for TypeList and TypeSet.	8 years ago
James Bardin	c4eefd4b5e	Allow primitive type in maps via all FieldReaders Now that we can read primitive type out of a map, each field reader needs to be able to set the proper type as expected.	10 years ago

James Nugent	074545e536	core: Use .% instead of .# for maps in state The flatmapped representation of state prior to this commit encoded maps and lists (and therefore by extension, sets) with a key corresponding to the number of elements, or the unknown variable indicator under a .# key and then individual items. For example, the list ["a", "b", "c"] would have been encoded as: listname.# = 3 listname.0 = "a" listname.1 = "b" listname.2 = "c" And the map {"key1": "value1", "key2", "value2"} would have been encoded as: mapname.# = 2 mapname.key1 = "value1" mapname.key2 = "value2" Sets use the hash code as the key - for example a set with a (fictional) hashcode calculation may look like: setname.# = 2 setname.12312512 = "value1" setname.56345233 = "value2" Prior to the work done to extend the type system, this was sufficient since the internal representation of these was effectively the same. However, following the separation of maps and lists into distinct first-class types, this encoding presents a problem: given a state file, it is impossible to tell the encoding of an empty list and an empty map apart. This presents problems for the type checker during interpolation, as many interpolation functions will operate on only one of these two structures. This commit therefore changes the representation in state of maps to use a "%" as the key for the number of elements. Consequently the map above will now be encoded as: mapname.% = 2 mapname.key1 = "value1" mapname.key2 = "value2" This has the effect of an empty list (or set) now being encoded as: listname.# = 0 And an empty map now being encoded as: mapname.% = 0 Therefore we can eliminate some nasty guessing logic from the resource variable supplier for interpolation, at the cost of having to migrate state up front (to follow in a subsequent commit). In order to reduce the number of potential situations in which resources would be "forced new", we continue to accept "#" as the count key when reading maps via helper/schema. There is no situation under which we can allow "#" as an actual map key in any case, as it would not be distinguishable from a list or set in state.	10 years ago
Martin Atkins	cc8e8a55de	helper/schema: Default hashing function for sets A common issue with new resource implementations is not considering parts of a complex structure that's used inside a set, which causes quirky behavior. The schema helper has enough information to provide a default reasonable implementation of a set function that includes all non-computed attributes in a deterministic way. Here we implement such a function and use it when no explicit hashing function is provided. In order to achieve this we encapsulate the construction of the zero value for a schema in a new method schema.ZeroValue, which allows us to put the fallback logic to the new default function in a single spot. It is no longer valid to use &Set{F: schema.Set} and all uses of that construct should be replaced with schema.ZeroValue().(*Set) .	11 years ago
