James Bardin	cdb80f68a8	Ensure better state normalization ... Fix checksum issue with remote state If we read a state file with "null" objects in a module and they become initialized to an empty map the state file may be written out with empty objects rather than "null", changing the checksum. If we can detect this, increment the serial number to prevent a conflict in atlas. Our fakeAtlas test server now needs to decode the state directly rather than using the ReadState function, so as to be able to read the state unaltered. The terraform.State data structures have initialization spread out throughout the package. More thoroughly initialize State during ReadState, and add a call to init() during WriteState as another normalization safeguard. Expose State.init through an exported Init() method, so that a new State can be completely realized outside of the terraform package. Additionally, the internal init now completely walks all internal state structures ensuring that all maps and slices are initialized. While it was mentioned before that the `init()` methods are problematic with too many call sites, expanding this out better exposes the entry points that will need to be refactored later for improved concurrency handling. The State structures had a mix of `omitempty` fields. Remove omitempty for all maps and slices as part of this normalization process. Make Lineage mandatory, which is now explicitly set in some tests.	10 years ago
James Nugent	d60365af02	core: Correctly ensure that State() is a copy ... The previous mechanism for testing state threw away the mutation made on the state by calling State() twice - this commit corrects the test to match the comment. In addition, we replace the custom copying logic with the copystructure library to simplify the code.	10 years ago
James Nugent	3ea3c657b5	core: Use OutputState in JSON instead of map ... This commit forward ports the changes made for 0.6.17, in order to store the type and sensitive flag against outputs. It also refactors the logic of the import for V0 to V1 state, and fixes up the call sites of the new format for outputs in V2 state. Finally we fix up tests which did not previously set a state version where one is required.	10 years ago
James Nugent	6aac79e194	state: Add support for outputs of multiple types ... This commit adds the groundwork for supporting module outputs of types other than string. In order to do so, the state version is increased from 1 to 2 (though the "public-facing" state version is actually as the first state file was binary). Tests are added to ensure that V2 (1) state is upgraded to V3 (2) state, though no separate read path is required since the V2 JSON will unmarshal correctly into the V3 structure. Outputs in a ModuleState are now of type map[string]interface{}, and a test covers round-tripping string, []string and map[string]string, which should cover all of the types in question. Type switches have been added where necessary to deal with the interface{} value, but they currently default to panicking when the input is not a string.	10 years ago
