Martin Atkins c23a7fce4e lang/funcs: Preserve IP address leading zero behavior from Go 1.16 
Go 1.17 includes a breaking change to both net.ParseIP and net.ParseCIDR
functions to reject IPv4 address octets written with leading zeros.

Our use of these functions as part of the various CIDR functions in the
Terraform language doesn't have the same security concerns that the Go
team had in evaluating this change to the standard library, and so we
can't justify an exception to our v1.0 compatibility promises on the same
sort of security grounds that the Go team used to justify their
compatibility exception.

For that reason, we'll now use our own fork of the Go library functions
which has the new check disabled in order to preserve the prior behavior.
We're taking this path, rather than pre-normalizing the IP address before
calling into the standard library, because an additional normalization
layer would be entirely new code and additional complexity, whereas this
fork is relatively minor in terms of code size and avoids any significant
changes to our own calls to these functions.

Thanks to the Kubernetes team for their prior work on carving out a subset
of the "net" package for their similar backward-compatibility concern.
Our "ipaddr" package here is a lightly-modified fork of their fork, with
only the comments changed to talk about Terraform instead of Kubernetes.

This fork is not intended for use in any other future feature
implementations, because they wouldn't be subject to the same
compatibility constraints as our existing functions. We will use these
forked implementations for new callers only if consistency with the
behavior of the existing functions is a key requirement.

Terraform Documentation

This directory contains the portions of the Terraform website that pertain to the core functionality, excluding providers and the overall configuration.

The files in this directory are intended to be used in conjunction with the terraform-website repository, which brings all of the different documentation sources together and contains the scripts for testing and building the site as a whole.

Previewing Changes

You should preview all of your changes locally before creating a pull request. The build includes content from this repository and the terraform-website repository, allowing you to preview the entire Terraform documentation site. If terraform-website isn't in your GOPATH, the preview command will clone it to your machine.

Set Up Local Environment

  1. Install Docker.

  2. Create a ~/go directory manually or by installing Go.

  3. Open terminal and set GOPATH as an environment variable:

    Bash: export $GOPATH=~/go(bash)

    Zsh: echo -n 'export GOPATH=~/go' >> ~/.zshrc

  4. Restart your terminal or command line session.

Launch Site Locally

  1. Navigate into your local terraform top-level directory and run make website.
  2. Open http://localhost:4567 in your web browser. While the preview is running, you can edit pages and Middleman will automatically rebuild them.
  3. When you're done with the preview, press ctrl-C in your terminal to stop the server.

Deploying Changes

Merge the PR to main. The changes will appear in the next major Terraform release.

If you need your changes to be deployed sooner, cherry-pick them to:

  • the current release branch (e.g. v1.0) and push. They will be deployed in the next minor version release (once every two weeks).
  • the stable-website branch and push. They will be included in the next site deploy (see below). Note that the release process resets stable-website to match the release tag, removing any additional commits. So, we recommend always cherry-picking to the version branch first and then to stable-website when needed.

Deployment

Currently, HashiCorp uses a CircleCI job to deploy the terraform.io site. This job can be run manually by many people within HashiCorp, and also runs automatically whenever a user in the HashiCorp GitHub org merges changes to master in the terraform-website repository.

New commits in this repository don't automatically deploy the [terraform.io][] site, but an unrelated site deploy will usually happen within a day. If you can't wait that long, you can do a manual CircleCI build or ask someone in the #proj-terraform-docs channel to do so:

  • Log in to circleci.com, and make sure you're viewing the HashiCorp organization.
  • Go to the terraform-website project's list of workflows.
  • Find the most recent "website-deploy" workflow, and click the "Rerun workflow from start" button (which looks like a refresh button with a numeral "1" inside).
