Daniel Banck	11d819048a	Store module source and version expressions ... Instead of evaluating and parsing a module source and version on configuration loading, we now simply store the expression. Decoding is now done during the graph-based configuration loading in the module install node.	1 month ago

Daniel Schmidt	958a1ae1e7	variable and output deprecation ... Variables can be deprecated through the `deprecated` attribute. If set the variable will emit a diagnostic if a values is passed to it. This entails both root level and module variables. Outputs can be deprecated through the `deprecated` attribute as well. If set wherever the value is used a diagnostic will be emitted. Root level outputs can not be deprecated. The only acceptable usage of a deprecated output is another deprecated output (forwarding the deprecation to the module user). If modules not under your control have deprecation warnings you can add a `suppress_deprecations_warnigns` attribute to the module call in question to silence any deeply nested warnings.	2 months ago

Martin Atkins	84df5562f2	moduleaddrs: Terraform now owns module source address normalization ... We've been gradually chipping away at how much we use go-getter for source packages, because it's generally been a bit of a nightmare and sharing it with other codebases means that any time someone wants to change something we end up needing to find some way to prevent it breaking Terraform's compatibility promises. Here we make one further step: Terraform owns the "detectors" idea that deals with source address normalization, and now always produces fully-qualified addresses for go-getter to chew on only for the getting and decompressing steps. Retaining go-getter for the actual getting part is helpful because we can then benefit from security fixes upstream, but Terraform owning the first layer of parsing means that we can fix in place the definition of what "module source address" syntax means, and thus we can avoid having everything in this codebase indirectly depend on go-getter just because it wants to parse module source addresses. Now only the module installer actually depends indirectly on go-getter, which finally disconnects go-getter's subtree from all of the remote state backend dependency graphs.	2 years ago
Martin Atkins	5d87e32eb9	moduleaddrs: Split module source address parsing from package addrs ... Our package addrs ends up getting imported from just about ever other package in Terraform, because it contains the types we use to talk about various different kinds of objects. Therefore we typically try to keep its transitive dependency graph relatively small, because anything it depends on becomes an indirect dependency of nearly everything else. A while back we moved the module source address models into package addrs, which also brought with them the code for parsing strings to produce those addresses. Unfortunately, remote module source addresses are defined using the external dependency go-getter, which is pretty heavy itself and also brings with it numerous other external dependencies such as the AWS SDK, the Google Cloud Platform SDK, etc. Since only relatively few packages actually need to _parse_ source addresses -- with most either not caring about them at all or only consuming addresses that were already parsed by someone else -- we'll move the parser functions into their own package, while keeping the resulting address types in package addrs. This does still retain the package addrs dependency on external module github.com/hashicorp/terraform-registry-address, which is not ideal but that one at least has a relatively shallow dependency subgraph, so there's not so much urgency to tidy that one.	2 years ago

Martin Atkins	affe2c3295	addrs: Expose the registry address parser's error messages ... Previously we ended up losing all of the error message detail produced by the registry address parser, because we treated any registry address failure as cause to parse the address as a go-getter-style remote address instead. That led to terrible feedback in the situation where the user _was_ trying to write a module address but it was invalid in some way. Although we can't really tighten this up in the default case due to our compatibility promises, it's never been valid to use the "version" argument with anything other than a registry address and so as a compromise here we'll use the presence of "version" as a heuristic for user intent to parse the source address as a registry address, and thus we can return a registry-address-specific error message in that case and thus give more direct feedback about what was wrong. This unfortunately won't help someone trying to install from the registry _without_ a version constraint, but I didn't want to let perfect be the enemy of the good here, particularly since we recommend using version constraints with registry modules anyway; indeed, that's one of the main benefits of using a registry rather than a remote source directly.	4 years ago
Martin Atkins	17b766c3ea	configs: EntersNewPackage methods for descendant modules ... Now that we (in the previous commit) refactored how we deal with module sources to do the parsing at config loading time rather than at module installation time, we can expose a method to centralize the determination for whether a particular module call (and its resulting Config object) enters a new external package. We don't use this for anything yet, but in later commits we will use this for some cross-module features that are available only for modules belonging to the same package, because we assume that modules grouped together in a package can change together and thus it's okay to permit a little more coupling of internal details in that case, which would not be appropriate between modules that are versioned separately.	5 years ago
Martin Atkins	1a8da65314	Refactoring of module source addresses and module installation ... It's been a long while since we gave close attention to the codepaths for module source address parsing and external module package installation. Due to their age, these codepaths often diverged from our modern practices such as representing address types in the addrs package, and encapsulating package installation details only in a particular location. In particular, this refactor makes source address parsing a separate step from module installation, which therefore makes the result of that parsing available to other Terraform subsystems which work with the configuration representation objects. This also presented the opportunity to better encapsulate our use of go-getter into a new package "getmodules" (echoing "getproviders"), which is intended to be the only part of Terraform that directly interacts with go-getter. This is largely just a refactor of the existing functionality into a new code organization, but there is one notable change in behavior here: the source address parsing now happens during configuration loading rather than module installation, which may cause errors about invalid addresses to be returned in different situations than before. That counts as backward compatible because we only promise to remain compatible with configurations that are _valid_, which means that they can be initialized, planned, and applied without any errors. This doesn't introduce any new error cases, and instead just makes a pre-existing error case be detected earlier. Our module registry client is still using its own special module address type from registry/regsrc for now, with a small shim from the new addrs.ModuleSourceRegistry type. Hopefully in a later commit we'll also rework the registry client to work with the new address type, but this commit is already big enough as it is.	5 years ago
Martin Atkins	31349a9c3a	Move configs/ to internal/configs/ ... This is part of a general effort to move all of Terraform's non-library package surface under internal in order to reinforce that these are for internal use within Terraform only. If you were previously importing packages under this prefix into an external codebase, you could pin to an earlier release tag as an interim solution until you've make a plan to achieve the same functionality some other way.	5 years ago
