kmoe	40ec62c139	command: make module installation interruptible Earlier work to make "terraform init" interruptible made the getproviders package context-aware in order to allow provider installation to be cancelled. Here we make a similar change for module installation, which is now also cancellable with SIGINT. This involves plumbing context through initwd and getmodules. Functions which can make network requests now include a context parameter whose cancellation cancels those requests. Since the module installation code is shared, "terraform get" is now also interruptible during module installation.	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	f25935649a	getmodules: Beginnings of a new package about Terraform module packages This new package aims to encapsulate all of our interactions with go-getter to fetch remote module packages, to ensure that the rest of Terraform will only use the small subset of go-getter functionality that our modern module installer uses. In older versions of Terraform, go-getter was the entire implementation of module installation, but along the way we found that several aspects of its design are poor fit for Terraform's needs, and so now we're using it as just an implementation detail of Terraform's handling of remote module packages only, hiding it behind this wrapper API which exposes only the services that our module installer needs. This new package isn't actually used yet, but in a later commit we will change all of the other callers to go-getter to only work indirectly through this package, so that this will be the only package that actually imports the go-getter packages.	5 years ago
