Alisdair McDiarmid	37006c5841	lang: Fix non-string key panics in map function ... The map function assumed that the key arguments were strings, and would panic if they were not. After this commit, calling `map(1, 2)` will result in a map `{"1" = 1}`, and calling `map(null, 1)` will result in a syntax error. Fixes #23346, fixes #23043	6 years ago

Martin Atkins	67d95b97ce	lang/funcs: templatefile requires valid variable names ... Previously the templatefile function would permit any arbitrary string as a variable name, but due to the HCL template syntax it would be impossible to refer to one that isn't a valid HCL identifier without causing an HCL syntax error. The HCL syntax errors are correct, but don't really point to the root cause of the problem. Instead, we'll pre-verify that the variable names are valid before we even try to render the template, and given a specialized error message that refers to the vars argument expression as the problematic part, which will hopefully make the resolution path clearer for a user encountering this situation. The syntax error still remains for situations where all of the variable names are correct but e.g. the user made a typo referring to one, which makes sense because in that case the problem _is_ inside the template.	6 years ago
Martin Atkins	ec9f950b3f	lang/funcs: Test actual error messages from templatefile ... This function has a number of different error cases with hopefully-helpful error messages for each, so it's good to test we're getting the error message we were actually expecting in each case.	6 years ago

James Bardin	f5bf9aa55d	make the merge function more precise ... This PR implements 2 changes to the merge function. - Rather than always defining the merge return type as dynamic, return a precise type when all argument types match, or all possible object attributes are known. - Always return a value containing all keys when the keys are known. This allows the use of merge output in for_each, even when keys are yet to be determined.	6 years ago
Martin Atkins	02576988c1	lang: "try" and "can" functions ... These are intended to make it easier to work with arbitrary data structures whose shape might not be known statically, such as the result of jsondecode(...) or yamldecode(...) of data from a separate system. For example, in an object value which has attributes that may or may not be set we can concisely provide a fallback value to use when the attribute isn't set: try(local.example.foo, "fallback-foo") Using a "try to evaluate" model rather than explicit testing fits better with the usual programming model of the Terraform language where values are normally automatically converted to the necessary type where possible: the given expression is subject to all of the same normal type conversions, which avoids inadvertently creating a more restrictive evaluation model as might happen if this were handled using checks like a hypothetical isobject(...) function, etc.	6 years ago

James Bardin	3839405d3d	correctly evaluate self in for_each resources ... The fallback type for GetResource from an EachMap is a cty.Object, because resource schemas may contain dynamically typed attributes. Check for an Object type in the evaluation of self, to use the proper GetAttr method when extracting the value.	6 years ago

James Bardin	bfce78064b	lang/eval: more evalContext fixups ... self references do not need to be added to `managedResource`, and in fact that could cause issues later if self is allowed in contexts other than managed resources. Coalesce 2 cases in the Referenceable switch, be take the ContainingResource address of an instance beforehand.	6 years ago
Martin Atkins	39e609d5fd	vendor: switch to HCL 2.0 in the HCL repository ... Previously we were using the experimental HCL 2 repository, but now we'll shift over to the v2 import path within the main HCL repository as part of actually releasing HCL 2.0 as stable. This is a mechanical search/replace to the new import paths. It also switches to the v2.0.0 release of HCL, which includes some new code that Terraform didn't previously have but should not change any behavior that matters for Terraform's purposes. For the moment the experimental HCL2 repository is still an indirect dependency via terraform-config-inspect, so it remains in our go.sum and vendor directories for the moment. Because terraform-config-inspect uses a much smaller subset of the HCL2 functionality, this does still manage to prune the vendor directory a little. A subsequent release of terraform-config-inspect should allow us to completely remove that old repository in a future commit.	6 years ago
Martin Atkins	f84ab99b7d	lang/funcs: cidrsubnets function ... This is a companion to cidrsubnet that allows bulk-allocation of multiple subnet addresses at once, with automatic numbering. Unlike cidrsubnet, cidrsubnets allows each of the allocations to have a different prefix length, and will pack the networks consecutively into the given address space. cidrsubnets can potentially create more complicated addressing schemes than cidrsubnet alone can, because it's able to take into account the full set of requested prefix lengths rather than just one at a time.	7 years ago
James Bardin	d4031918d1	parse resource refs correctly ... Now that we only evaluate whole resources, we can parse resource refs correct as the resource, rather than an unknown instance.	7 years ago
James Bardin	c49f976308	change lang eval to also only lookup resources ... Continue only evaluating resource at a whole and push the indexing of the resource down into the expression evaluation. The exception here is that `self` must be an instance which must be extracted from the resource. We now also add the entire resource to the context, which was previously only partially populated with the self referenced instance.	7 years ago
James Bardin	86bf674246	change GetResourceInstance to GetResource ... In order to allow lazy evaluation of resource indexes, we can't index resources immediately via GetResourceInstance. Change the evaluation to always return whole Resources via GetResource, and index individual instances during expression evaluation. This will allow us to always check for invalid index errors rather than returning an unknown value and ignoring it during apply.	7 years ago

Brian Flad	19cf34114f	lang/funcs: Switch fileset() function glob implementation to github.com/bmatcuk/doublestar to support additional glob patterns ...

Brian Flad	af7f6ef441	lang/funcs: Update fileset() function to include path as separate first argument, automatically trim the path argument from results, and ensure results are always canonical with forward slash path separators ... Reference: https://github.com/hashicorp/terraform/pull/22523#pullrequestreview-279694703 These changes center around better function usability and consistency with other functions. The function has not yet been released, so these breaking changes can be applied safely.	7 years ago
Brian Flad	d48d9ed766	lang/funcs: Add fileset function ... Reference: https://github.com/hashicorp/terraform/issues/16697 Enumerates a set of regular file names from a given glob pattern. Implemented via the Go stdlib `path/filepath.Glob()` functionality. Notably, stdlib does not support `**` or `{}` extended patterns. See also: https://github.com/golang/go/issues/11862 To support the extended glob patterns, it will require adding a dependency on a third party library or adding our own matching code.	7 years ago

Martin Atkins	135afaeb9c	lang: "regex" and "regexall" functions ... These existing upstream cty functions allow matching strings against regular expression patterns, which can be useful if you need to consume a non-standard string format that Terraform doesn't (and can't) have a built-in function for.	7 years ago

James Bardin	6e222375c7	invlaid use of dynamic with attrs should not panic ... Mistakenly using dynamic on an attribute will lead to a panic when attempting to resolve variable references with a partial body, because the dynamic blocks have yet to be expanded and validated. Check that the block element type is actually an object before generating a schema.	7 years ago

Lars Eric Scheidler	aa07806bfc	lang/funcs: New "uuidv5" function ... This generates name-based uuids, rather than pseudorandom uuids as with the "uuid" function.	7 years ago
Martin Atkins	382e1ca821	lang: yamldecode and yamlencode functions ... These follow the same principle as jsondecode and jsonencode, but use YAML instead of JSON. YAML has a much more complex information model than JSON, so we can only support a subset of it during decoding, but hopefully the subset supported here is a useful one. Because there are many different ways to _generate_ YAML, the yamlencode function is forced to make some decisions, and those decisions are likely to affect compatibility with other real-world YAML parsers. Although the format here is intended to be generic and compatible, we may find that there are problems with it that'll we'll want to adjust for in a future release, so yamlencode is therefore marked as experimental for now until the underlying library is ready to commit to ongoing byte-for-byte compatibility in serialization. The main use-case here is met by yamldecode, which will allow reading in files written in YAML format by humans for use in Terraform modules, in situations where a higher-level input format than direct Terraform language declarations is helpful.	7 years ago
Martin Atkins	f9a73d48db	lang: "range" function ... This is similar to the function of the same name in Python, generating a sequence of numbers as a list that can then be used in other sequence-oriented operations. The primary use-case for it is to turn a count expressed as a number into a list of that length, which can then be iterated over or passed to a collection function to produce that number of something else, as shown in the example at the end of its documentation page.	7 years ago
