Martin Atkins	1879a39d2d	configs: Refined error messages for mismatched provider passing ... This set of diagnostic messages is under a number of unusual constraints that make them tough to get right: - They are discussing a couple finicky concepts which authors are likely to be encountering for the first time in these error messages: the idea of "local names" for providers, the relationship between those and provider source addresses, and additional ("aliased") provider configurations. - They are reporting concerns that span across a module call boundary, and so need to take care to be clear about whether they are talking about a problem in the caller or a problem in the callee. - Some of them are effectively deprecation warnings for features that might be in use by a third-party module that the user doesn't control, in which case they have no recourse to address them aside from opening a feature request with the upstream module maintainer. - Terraform has, for backward-compatibility reasons, a lot of implied default behaviors regarding providers and provider configurations, and these errors can arise in situations where Terraform's assumptions don't match the author's intent, and so we need to be careful to explain what Terraform assumed in order to make the messages understandable. After seeing some confusion with these messages in the community, and being somewhat confused by some of them myself, I decided to try to edit them a bit for consistency of terminology (both between the messages and with terminology in our docs), being explicit about caller vs. callee by naming them in the messages, and making explicit what would otherwise be implicit with regard to the correspondences between provider source addresses and local names. My assumed audience for all of these messages is the author of the caller module, because it's the caller who is responsible for creating the relationship between caller and callee. As much as possible I tried to make the messages include specific actions for that author to take to quiet the warning or fix the error, but some of the warnings are only fixable by the callee's maintainer and so those messages are, in effect, a suggestion to send a request to the author to stop using a deprecated feature. I think these new messages are also not ideal by any means, because it's just tough to pack so much information into concise messages while being clear and consistent, but I hope at least this will give users seeing these messages enough context to infer what's going on, possibly with the help of our documentation. I intentionally didn't change which cases Terraform will return warnings or errors -- only the message texts -- although I did highlight in a comment in one of the tests that what it is a asserting seems a bit suspicious to me. I don't intend to address that here; instead, I intend that note to be something to refer to if we later see a bug report that calls that behavior into question. This does actually silence some _unrelated_ warnings and errors in cases where a provider block has an invalid provider local name as its label, because our other functions for dealing with provider addresses are written to panic if given invalid addresses under the assumption that earlier code will have guarded against that. Doing this allowed for the provider configuration validation logic to safely include more information about the configuration as helpful context, without risking tripping over known-invalid configuration and panicking in the process.	4 years ago
James Bardin	0771a214d8	skip provider resolution when there are errors ... If there are errors loading the configuration, don't try to resolve the provider names, as those names may not even be valid.	4 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
