core: support native list variables in config This commit adds support for native list variables and outputs, building up on the previous change to state. Interpolation functions now return native lists in preference to StringList. List variables are defined like this: variable "test" { # This can also be inferred type = "list" default = ["Hello", "World"] } output "test_out" { value = "${var.a_list}" } This results in the following state: ``` ... "outputs": { "test_out": [ "hello", "world" ] }, ... ``` And the result of terraform output is as follows: ``` $ terraform output test_out = [ hello world ] ``` Using the output name, an xargs-friendly representation is output: ``` $ terraform output test_out hello world ``` The output command also supports indexing into the list (with appropriate range checking and no wrapping): ``` $ terraform output test_out 1 world ``` Along with maps, list outputs from one module may be passed as variables into another, removing the need for the `join(",", var.list_as_string)` and `split(",", var.list_as_string)` which was previously necessary in Terraform configuration. This commit also updates the tests and implementations of built-in interpolation functions to take and return native lists where appropriate. A backwards compatibility note: previously the concat interpolation function was capable of concatenating either strings or lists. The strings use case was deprectated a long time ago but still remained. Because we cannot return `ast.TypeAny` from an interpolation function, this use case is no longer supported for strings - `concat` is only capable of concatenating lists. This should not be a huge issue - the type checker picks up incorrect parameters, and the native HIL string concatenation - or the `join` function - can be used to replicate the missing behaviour.

helper/schema: Normalize bools to "true"/"false" in diffs For a long time now, the diff logic has relied on the behavior of `mapstructure.WeakDecode` to determine how various primitives are converted into strings. The `schema.DiffString` function is used for all primitive field types: TypeBool, TypeInt, TypeFloat, and TypeString. The `mapstructure` library's string representation of booleans is "0" and "1", which differs from `strconv.FormatBool`'s "false" and "true" (which is used in writing out boolean fields to the state). Because of this difference, diffs have long had the potential for cosmetically odd but semantically neutral output like: "true" => "1" "false" => "0" So long as `mapstructure.Decode` or `strconv.ParseBool` are used to interpret these strings, there's no functional problem. We had our first clear functional problem with #6005 and friends, where users noticed diffs like the above showing up unexpectedly and causing troubles when `ignore_changes` was in play. This particular bug occurs down in Terraform core's EvalIgnoreChanges. There, the diff is modified to account for ignored attributes, and special logic attempts to handle properly the situation where the ignored attribute was going to trigger a resource replacement. That logic relies on the string representations of the Old and New fields in the diff to be the same so that it filters properly. So therefore, we now get a bug when a diff includes `Old: "0", New: "false"` since the strings do not match, and `ignore_changes` is not properly handled. Here, we introduce `TypeBool`-specific normalizing into `finalizeDiff`. I spiked out a full `diffBool` function, but figuring out which pieces of `diffString` to duplicate there got hairy. This seemed like a simpler and more direct solution. Fixes #6005 (and potentially others!)

core: support native list variables in config This commit adds support for native list variables and outputs, building up on the previous change to state. Interpolation functions now return native lists in preference to StringList. List variables are defined like this: variable "test" { # This can also be inferred type = "list" default = ["Hello", "World"] } output "test_out" { value = "${var.a_list}" } This results in the following state: ``` ... "outputs": { "test_out": [ "hello", "world" ] }, ... ``` And the result of terraform output is as follows: ``` $ terraform output test_out = [ hello world ] ``` Using the output name, an xargs-friendly representation is output: ``` $ terraform output test_out hello world ``` The output command also supports indexing into the list (with appropriate range checking and no wrapping): ``` $ terraform output test_out 1 world ``` Along with maps, list outputs from one module may be passed as variables into another, removing the need for the `join(",", var.list_as_string)` and `split(",", var.list_as_string)` which was previously necessary in Terraform configuration. This commit also updates the tests and implementations of built-in interpolation functions to take and return native lists where appropriate. A backwards compatibility note: previously the concat interpolation function was capable of concatenating either strings or lists. The strings use case was deprectated a long time ago but still remained. Because we cannot return `ast.TypeAny` from an interpolation function, this use case is no longer supported for strings - `concat` is only capable of concatenating lists. This should not be a huge issue - the type checker picks up incorrect parameters, and the native HIL string concatenation - or the `join` function - can be used to replicate the missing behaviour.

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.

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.

core: support native list variables in config This commit adds support for native list variables and outputs, building up on the previous change to state. Interpolation functions now return native lists in preference to StringList. List variables are defined like this: variable "test" { # This can also be inferred type = "list" default = ["Hello", "World"] } output "test_out" { value = "${var.a_list}" } This results in the following state: ``` ... "outputs": { "test_out": [ "hello", "world" ] }, ... ``` And the result of terraform output is as follows: ``` $ terraform output test_out = [ hello world ] ``` Using the output name, an xargs-friendly representation is output: ``` $ terraform output test_out hello world ``` The output command also supports indexing into the list (with appropriate range checking and no wrapping): ``` $ terraform output test_out 1 world ``` Along with maps, list outputs from one module may be passed as variables into another, removing the need for the `join(",", var.list_as_string)` and `split(",", var.list_as_string)` which was previously necessary in Terraform configuration. This commit also updates the tests and implementations of built-in interpolation functions to take and return native lists where appropriate. A backwards compatibility note: previously the concat interpolation function was capable of concatenating either strings or lists. The strings use case was deprectated a long time ago but still remained. Because we cannot return `ast.TypeAny` from an interpolation function, this use case is no longer supported for strings - `concat` is only capable of concatenating lists. This should not be a huge issue - the type checker picks up incorrect parameters, and the native HIL string concatenation - or the `join` function - can be used to replicate the missing behaviour.

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.

core: support native list variables in config This commit adds support for native list variables and outputs, building up on the previous change to state. Interpolation functions now return native lists in preference to StringList. List variables are defined like this: variable "test" { # This can also be inferred type = "list" default = ["Hello", "World"] } output "test_out" { value = "${var.a_list}" } This results in the following state: ``` ... "outputs": { "test_out": [ "hello", "world" ] }, ... ``` And the result of terraform output is as follows: ``` $ terraform output test_out = [ hello world ] ``` Using the output name, an xargs-friendly representation is output: ``` $ terraform output test_out hello world ``` The output command also supports indexing into the list (with appropriate range checking and no wrapping): ``` $ terraform output test_out 1 world ``` Along with maps, list outputs from one module may be passed as variables into another, removing the need for the `join(",", var.list_as_string)` and `split(",", var.list_as_string)` which was previously necessary in Terraform configuration. This commit also updates the tests and implementations of built-in interpolation functions to take and return native lists where appropriate. A backwards compatibility note: previously the concat interpolation function was capable of concatenating either strings or lists. The strings use case was deprectated a long time ago but still remained. Because we cannot return `ast.TypeAny` from an interpolation function, this use case is no longer supported for strings - `concat` is only capable of concatenating lists. This should not be a huge issue - the type checker picks up incorrect parameters, and the native HIL string concatenation - or the `join` function - can be used to replicate the missing behaviour.

helper/schema: Normalize bools to "true"/"false" in diffs For a long time now, the diff logic has relied on the behavior of `mapstructure.WeakDecode` to determine how various primitives are converted into strings. The `schema.DiffString` function is used for all primitive field types: TypeBool, TypeInt, TypeFloat, and TypeString. The `mapstructure` library's string representation of booleans is "0" and "1", which differs from `strconv.FormatBool`'s "false" and "true" (which is used in writing out boolean fields to the state). Because of this difference, diffs have long had the potential for cosmetically odd but semantically neutral output like: "true" => "1" "false" => "0" So long as `mapstructure.Decode` or `strconv.ParseBool` are used to interpret these strings, there's no functional problem. We had our first clear functional problem with #6005 and friends, where users noticed diffs like the above showing up unexpectedly and causing troubles when `ignore_changes` was in play. This particular bug occurs down in Terraform core's EvalIgnoreChanges. There, the diff is modified to account for ignored attributes, and special logic attempts to handle properly the situation where the ignored attribute was going to trigger a resource replacement. That logic relies on the string representations of the Old and New fields in the diff to be the same so that it filters properly. So therefore, we now get a bug when a diff includes `Old: "0", New: "false"` since the strings do not match, and `ignore_changes` is not properly handled. Here, we introduce `TypeBool`-specific normalizing into `finalizeDiff`. I spiked out a full `diffBool` function, but figuring out which pieces of `diffString` to duplicate there got hairy. This seemed like a simpler and more direct solution. Fixes #6005 (and potentially others!)
