fatahfattah	8a31f0a6c8	addrs: ModuleSourceRemote.String correctly handles query string in URL ... Previously it would append the "subdir" portion onto the query string, producing an invalid result.	4 years ago
Radek Simko	7feef1c4aa	Use hashicorp/terraform-registry-address as a decoupled library (#28338) ... * refactor: Use tfaddr for provider address parsing * refactor: Use tfaddr for module address parsing * deps: introduce hashicorp/terraform-registry-address	4 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	51b0aee36c	addrs: ModuleRegistryPackage for representing module registry packages ... Previously we had a separation between ModuleSourceRemote and ModulePackage as a way to represent within the type system that there's an important difference between a module source address and a package address, because module packages often contain multiple modules and so a ModuleSourceRemote combines a ModulePackage with a subdirectory to represent one specific module. This commit applies that same strategy to ModuleSourceRegistry, creating a new type ModuleRegistryPackage to represent the different sort of package that we use for registry modules. Again, the main goal here is to try to reflect the conceptual modelling more directly in the type system so that we can more easily verify that uses of these different address types are correct. To make use of that, I've also lightly reworked initwd's module installer to use addrs.ModuleRegistryPackage directly, instead of a string representation thereof. This was in response to some earlier commits where I found myself accidentally mixing up package addresses and source addresses in the installRegistryModule method; with this new organization those bugs would've been caught at compile time, rather than only at unit and integration testing time. While in the area anyway, I also took this opportunity to fix some historical confusing names of fields in initwd.ModuleInstaller, to be clearer that they are only for registry packages and not for all module source address types.	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	2e7db64968	addrs: Representation of module source addresses ... We've previously had the syntax and representation of module source addresses pretty sprawled around the codebase and intermingled with other systems such as the module installer. I've created a factored-out implementation here with the intention of enabling some later refactoring to centralize the address parsing as part of configuration decoding, and thus in turn allow the parsing result to be seen by other parts of Terraform that interact with configuration objects, so that they can more robustly handle differences between local and remote modules, and can present module addresses consistently in the UI.	5 years ago
