Martin Atkins	fedbd6c3b8	helper/plugin: fix panic with empty objects in normalizeNullValues ... cty.Value.AsValueMap can return nil if called on an empty map or object. The logic above was dealing with that case for maps, but object types were falling through into this codepath and panicking when trying to assign a new key into the nil dstMap. This also includes a bonus fix where we were calling ty.ElementType in a switch case that accepts object types. Object types don't have a single element type, so we can't call ElementType on those (that also panics) but we _can_ use the type of the value we selected from src to construct our placeholder null value.	7 years ago
James Bardin	ba081f5de4	change copyMissingValues to normalizeNullValues ... While copyMissingValues was meant to re-insert empty values that were null after apply, it turns out plan is sometimes not predictable as well. normalizeNullValue is meant to fix up any null/empty transitions between to values, and be useful during plan as well. For plan the function only concerns itself with individual, known values, and skips sets entirely. The result of running with plan == true is that only changes between empty and null collections should be fixed.	7 years ago
James Bardin	4f691c5988	don't replace null strings with empty strings ... This adds unexpected values in some cases, and since the case this handles is only within set objects, we'll deal woth this when tackling the sets themselves.	7 years ago
James Bardin	b55ec74c27	add copyMissingValues for normalizing shimmed Vals ... Zero values and empty containers can be lost during the shimming process, and during the provider's Apply step. If we have known zero value containers and primitives in the source, which appear as null values in the destination, we copy over the zero value. Sets (and lists to an extent) are more difficult, since there before and after indexes may not correlate. In that case we take the entire container if it's wholly known, expecting the provider to have correctly handled the value.	7 years ago
James Bardin	8300d65539	don't strip sets with count 1 when normalizing ... normalizeFlatmapContainers should retain sets with a count of 1, and convert sets with a count of 0 if they were 1 before the Apply step.	7 years ago
James Bardin	5f9b189fcf	catch conversion errors in PrepareProviderConfig ... Errors were being ignore with the intention that they would be caught later in validation, but it turns out we nee dto catch those earlier. The legacy schemas also allowed providers to set and empty string for a bool value, which we need to handle here, since it's not being handled from user input like a normal config value.	8 years ago
James Bardin	6f4d86094f	preserve possible zero values when normalizing ... When normalizing flatmapped containers, compare the attributes to the prior state and preserve pre-existing zero-length or unknown values. A zero-length value that was previously unknown is preserved as a zero-length value, as that may have been computed as such by the provider.	8 years ago

Martin Atkins	4fe9632f09	plugin: Establish our current plugin protocol as version 5 ... The main significant change here is that the package name for the proto definition is "tfplugin5", which is important because this name is part of the wire protocol for references to types defined in our package. Along with that, we also move the generated package into "internal" to make it explicit that importing the generated Go package from elsewhere is not the right approach for externally-implemented SDKs, which should instead vendor the proto definition they are using and generate their own stubs to ensure that the wire protocol is the only hard dependency between Terraform Core and plugins. After this is merged, any provider binaries built against our helper/schema package will need to be rebuilt so that they use the new "tfplugin5" package name instead of "proto". In a future commit we will include more elaborate and organized documentation on how an external codebase might make use of our RPC interface definition to implement an SDK, but the primary concern here is to ensure we have the right wire package name before release.	8 years ago

James Bardin	17ecda53b5	strip empty containers from flatmap attributes ... In order to prevent mismatched states between read/plan/apply, we need to ensure that the attributes are generated consistently each time. Because of the various ways in which helper/schema and the hcl2 shims interpret empty values, the only way to ensure consistency is to always remove them altogether.	8 years ago
James Bardin	6dad121e70	insert resource timeouts into the config schema ... Resource timeouts were a separate config block, but did not exist in the resource schema. Insert any defined timeouts when generating the configshema.Block so that the fields can be accepted and validated by core.	8 years ago
James Bardin	a8f75bc554	don't set defaults for deprecated or removed ... These may still have defaults set, even if they are not intended to be used.	8 years ago
James Bardin	e077c9ce95	Insert default values into provider config ... Add any top-level default attributes from the provider schema into Null config values.	8 years ago
James Bardin	caf74a218d	initialize empty diff in apply ... While the schema Diff fucntion returns a nil diff when creating an empty (except for id) resource, the Apply function expects the diff to be initialized and ampty.	8 years ago
James Bardin	0b8c38207a	a plan with no diff should return proposed state ... PlanResourceChange isn't returning the diff, but rather it is returning the destired state. If the propsed state results in a nil diff, then, the propsed state is what should be returned. Make sure Meta fields are not nil, as the schema package expects those to be initialised.	8 years ago
James Bardin	63dcdbe948	helper/plugin package for grpc servers ... The new helper/plugin package contains the grpc servers for handling the new plugin protocol The GRPCProviderServer and GRPCProvisionerServer handle the grpc plugin protocol, and convert the requests to the legacy schema.Provider and schema.Provisioner methods.	8 years ago
