Martin Atkins	b9a93a0fe7	Move addrs/ to internal/addrs/ ... 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
Martin Atkins	b3f5c7f1e6	command/init: Read, respect, and update provider dependency locks ... This changes the approach used by the provider installer to remember between runs which selections it has previously made, using the lock file format implemented in internal/depsfile. This means that version constraints in the configuration are considered only for providers we've not seen before or when -upgrade mode is active.	6 years ago
Martin Atkins	6694cfaa0e	getproviders: Add a real type Hash for package hashes ... The logic for what constitutes a valid hash and how different hash schemes are represented was starting to get sprawled over many different files and packages. Consistently with other cases where we've used named types to gather the definition of a particular string into a single place and have the Go compiler help us use it properly, this introduces both getproviders.Hash representing a hash value and getproviders.HashScheme representing the idea of a particular hash scheme. Most of this changeset is updating existing uses of primitive strings to uses of getproviders.Hash. The new type definitions are in internal/getproviders/hash.go.	6 years ago
Alisdair McDiarmid	8e87ccb689	providercache: Lazily detect executable file ... Instead of searching the installed provider package directory for a binary as we install it, we can lazily detect the executable as it is required. Doing so allows us to separately report an invalid unpacked package, giving the user more actionable error messages.	6 years ago
Martin Atkins	9489672d54	internal/getproviders: Package hashing for local filesystem packages ... We previously had this functionality available for cached packages in the providercache package. This moves the main implementation of this over to the getproviders package and then implements it also for PackageMeta, allowing us to compute hashes in a consistent way across both of our representations of a provider package. The new methods on PackageMeta will only be effective for packages in the local filesystem because we need direct access to the contents in order to produce the hash. Hopefully in future the registry protocol will be able to also provide hashes using this content-based (rather than archive-based) algorithm and then we'll be able to make this work for PackageMeta referring to a package obtained from a registry too, but hashes for local packages only are still useful for some cases right now, such as generating mirror directories in the "terraform providers mirror" command.	6 years ago
Martin Atkins	f6a7a4868b	internal/providercache: Hashing of contents of cached packages ... For the old-style provider cache directory model we hashed the individual executable file for each provider. That's no longer appropriate because we're giving each provider package a whole directory to itself where it can potentially have many files. This therefore introduces a new directory-oriented hashing algorithm, and it's just using the Go Modules directory hashing algorithm directly because that's already had its cross-platform quirks and other wrinkles addressed during the Go Modules release process, and is now used prolifically enough in Go codebases that breaking changes to the upstream algorithm would be very expensive to the Go ecosystem. This is also a bit of forward planning, anticipating that later we'll use hashes in a top-level lock file intended to be checked in to user version control, and then use those hashes also to verify packages _during_ installation, where we'd need to be able to hash unpacked zip files. The Go Modules hashing algorithm is already implemented to consistently hash both a zip file and an unpacked version of that zip file.	6 years ago
Martin Atkins	d13001830b	providercache: A package to encapsulate management of provider cache dirs ... Historically our logic to handle discovering and installing providers has been spread across several different packages. This package is intended to become the home of all logic related to what is now called "provider cache directories", which means directories on local disk where Terraform caches providers in a form that is ready to run. That includes both logic related to interrogating items already in a cache (included in this commit) and logic related to inserting new items into the cache from upstream provider sources (to follow in later commits). These new codepaths are focused on providers and do not include other plugin types (provisioners and credentials helpers), because providers are the only plugin type that is represented by a heirarchical, decentralized namespace and the only plugin type that has an auto-installation protocol defined. The existing codepaths will remain to support the handling of the other plugin types that require manual installation and that use only a flat, locally-defined namespace.	6 years ago
