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	01be1a5ecd	Check for interpolated values when reading a map ... Accessing an interpolated value in a map through ConfigFieldReader can fail, because GetRaw can't access interpolated values, so check if the value exists at all by looking in the config. If the config has a value, assume our map's value is interpolated and proceed as such. We also need to lookup the correct schema to properly read a field from a nested structure. - Maps previously always defaulted to TypeString. Now check if Elem is a ValueType and use that if applicable - Lists now return the schema for nested element types, defaulting to a TypeString like maps. This only allows maps and lists to be nested one level deep, and the inner map or list must only contain string values.	10 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	7b6df27e4a	helper/schema: Read native maps from configuration ... This adds a test and the support necessary to read from native maps passed as variables via interpolation - for example: ``` resource ...... { mapValue = "${var.map}" } ``` We also add support for interpolating maps from the flat-mapped resource config, which is necessary to support assignment of computed maps, which is now valid. Unfortunately there is no good way to distinguish between a list and a map in the flatmap. In lieu of changing that representation (which is risky), we assume that if all the keys are numeric, this is intended to be a list, and if not it is intended to be a map. This does preclude maps which have purely numeric keys, which should be noted as a backwards compatibility concern.	10 years ago
Sander van Harmelen	ef4726bd50	Change Set internals and make (extreme) performance improvements ... Changing the Set internals makes a lot of sense as it saves doing conversions in multiple places and gives a central place to alter the key when a item is computed. This will have no side effects other then that the ordering is now based on strings instead on integers, so the order will be different. This will however have no effect on existing configs as these will use the individual codes/keys and not the ordering to determine if there is a diff or not. Lastly (but I think also most importantly) there is a fix in this PR that makes diffing sets extremely more performand. Before a full diff required reading the complete Set for every single parameter/attribute you wanted to diff, while now it only gets that specific parameter. We have a use case where we have a Set that has 18 parameters and the set consist of about 600 items (don't ask 😉). So when doing a diff it would take 100% CPU of all cores and stay that way for almost an hour before being able to complete the diff. Debugging this we learned that for retrieving every single parameter it made over 52.000 calls to `func (c *ResourceConfig) get(..)`. In this function a slice is created and used only for the duration of the call, so the time needed to create all needed slices and on the other hand the time the garbage collector needed to clean them up again caused the system to cripple itself. Next to that there are also some expensive reflect calls in this function which also claimed a fair amount of CPU time. After this fix the number of calls needed to get a single parameter dropped from 52.000+ to only 2! 😃	11 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

Paul Hinze	5d4e69cc80	helper/schema: apply schema defaults at the field level when reading from config ... We were waiting until the higher-level (m schemaMap) diffString method to apply defaults, which was messing with set hashcode evaluation for cases when a field with a default is included in the hash function. fixes #824	11 years ago
