Martin Atkins	7bee77bdd3	command: Start of propagating OpenTelemetry context ... Several times over the years we've considered adding tracing instrumentation to Terraform, since even when running in isolation as a CLI program it has a "distributed system-like" structure, with lots of concurrent internal work and also some work delegated to provider plugins that are essentially temporarily-running microservices. However, it's always felt a bit overwhelming to do it because much of Terraform predates the Go context.Context idiom and so it's tough to get a clean chain of context.Context values all the way down the stack without disturbing a lot of existing APIs. This commit aims to just get that process started by establishing how a context can propagate from "package main" into the command package, focusing initially on "terraform init" and some other commands that share some underlying functions with that command. OpenTelemetry has emerged as a de-facto industry standard and so this uses its API directly, without any attempt to hide it behind an abstraction. The OpenTelemetry API is itself already an adapter layer, so we should be able to swap in any backend that uses comparable concepts. For now we just discard the tracing reports by default, and allow users to opt in to delivering traces over OTLP by setting an environment variable when running Terraform (the environment variable was established in an earlier commit, so this commit builds on that.) When tracing collection is enabled, every Terraform CLI run will generate at least one overall span representing the command that was run. Some commands might also create child spans, but most currently do not.	3 years ago

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.	4 years ago
Martin Atkins	ffe056bacb	Move command/ to internal/command/ ... 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
