-# Contributing to Packer
-
-**First:** if you're unsure or afraid of _anything_, just ask or submit the
-issue or pull request anyway. You won't be yelled at for giving your best
-effort. The worst that can happen is that you'll be politely asked to change
-something. We appreciate any sort of contributions, and don't want a wall of
-rules to get in the way of that.
-
-However, for those individuals who want a bit more guidance on the best way to
-contribute to the project, read on. This document will cover what we're looking
-for. By addressing all the points we're looking for, it raises the chances we
-can quickly merge or address your contributions.
-
-## Issues
-
-### Reporting an Issue
-
-* Make sure you test against the latest released version. It is possible we
-  already fixed the bug you're experiencing.
-
-* Run the command with debug output with the environment variable `PACKER_LOG`.
-  For example: `PACKER_LOG=1 packer build template.json`. Take the _entire_
-  output and create a [gist](https://gist.github.com) for linking to in your
-  issue. Packer should strip sensitive keys from the output, but take a look
-  through just in case.
-
-* Provide a reproducible test case. If a contributor can't reproduce an issue,
-  then it dramatically lowers the chances it'll get fixed. And in some cases,
-  the issue will eventually be closed.
-
-* Respond promptly to any questions made by the Packer team to your issue. Stale
-  issues will be closed.
-
-### Issue Lifecycle
-
-1. The issue is reported.
-
-2. The issue is verified and categorized by a Packer collaborator.
-   Categorization is done via tags. For example, bugs are marked as "bugs" and
-   simple fixes are marked as "good first issue".
-
-3. Unless it is critical, the issue is left for a period of time (sometimes many
-   weeks), giving outside contributors a chance to address the issue.
-
-4. The issue is addressed in a pull request or commit. The issue will be
-   referenced in the commit message so that the code that fixes it is clearly
-   linked.
-
-5. The issue is closed.
-
-## Setting up Go
-
-If you have never worked with Go before, you will have to install its
-runtime in order to build packer.
-
-1. This project always releases from the latest version of golang. [Install go](https://golang.org/doc/install#install)
-
-## Setting up Packer for dev
-
-If/when you have go installed you can already `go get` packer and `make` in
-order to compile and test Packer. These instructions target
-POSIX-like environments (macOS, Linux, Cygwin, etc.) so you may need to
-adjust them for Windows or other shells.
-The instructions below are for go 1.7. or later.
-
-1. Download the Packer source (and its dependencies) by running
-   `go get github.com/hashicorp/packer`. This will download the Packer source to
-   `$GOPATH/src/github.com/hashicorp/packer`.
-
-2. When working on Packer, first `cd $GOPATH/src/github.com/hashicorp/packer`
-   so you can run `make` and easily access other files. Run `make help` to get
-   information about make targets.
-
-3. Make your changes to the Packer source. You can run `make` in
-   `$GOPATH/src/github.com/hashicorp/packer` to run tests and build the Packer
-   binary. Any compilation errors will be shown when the binaries are
-   rebuilding. If you don't have `make` you can simply run
-   `go build -o bin/packer .` from the project root.
-
-4. After running building Packer successfully, use
-   `$GOPATH/src/github.com/hashicorp/packer/bin/packer` to build a machine and
-   verify your changes work. For instance:
-   `$GOPATH/src/github.com/hashicorp/packer/bin/packer build template.json`.
-
-5. If everything works well and the tests pass, run `go fmt` on your code before
-   submitting a pull-request.
-
-### Windows Systems
-On windows systems you need at least the [MinGW Tools](http://www.mingw.org/), e.g. install via [choco](https://chocolatey.org/):
-
-```
-choco install mingw -y
-```
-
-This installs the GCC compiler, as well as a ```mingw32-make``` which can be used wherever
-this documentation mentions ```make```
-
-when building using ```go``` you also need to mention the windows
-executable extension
-
-```
-go build -o bin/packer.exe
-```
-
-
-### Opening an Pull Request
-
-Thank you for contributing! When you are ready to open a pull-request, you will
-need to [fork
-Packer](https://github.com/hashicorp/packer#fork-destination-box), push your
-changes to your fork, and then open a pull-request.
-
-For example, my github username is `cbednarski`, so I would do the following:
-
-```
-git checkout -b f-my-feature
-# Develop a patch.
-git push https://github.com/cbednarski/Packer f-my-feature
-```
-
-From there, open your fork in your browser to open a new pull-request.
-
-**Note:** Go infers package names from their file paths. This means `go build`
-will break if you `git clone` your fork instead of using `go get` on the main
-Packer project.
-
-**Note:** See '[Working with
-forks](https://help.github.com/articles/working-with-forks/)' for a better way
-to use `git push ...`.
-
-### Pull Request Lifecycle
-
-1. You are welcome to submit your pull request for commentary or review before
-  it is fully completed. Please prefix the title of your pull request with
-  "[WIP]" to indicate this. It's also a good idea to include specific questions
-  or items you'd like feedback on.
-
-2. Once you believe your pull request is ready to be merged, you can remove any
-  "[WIP]" prefix from the title and a core team member will review.
-
-3. One of Packer's core team members will look over your contribution and
-  either merge, or provide comments letting you know if there is anything left
-  to do. We do our best to provide feedback in a timely manner, but it may take
-  some time for us to respond. We may also have questions that we need answered
-  about the code, either because something doesn't make sense to us or because
-  we want to understand your thought process.
-
-4. If we have requested changes, you can either make those changes or, if you
-  disagree with the suggested changes, we can have a conversation about our
-  reasoning and agree on a path forward. This may be a multi-step process. Our
-  view is that pull requests are a chance to collaborate, and we welcome
-  conversations about how to do things better. It is the contributor's
-  responsibility to address any changes requested. While reviewers are happy to
-  give guidance, it is unsustainable for us to perform the coding work necessary
-  to get a PR into a mergeable state.
-
-5. Once all outstanding comments and checklist items have been addressed, your
-  contribution will be merged! Merged PRs will be included in the next
-  Packer release. The core team takes care of updating the
-  [CHANGELOG.md](../CHANGELOG.md) as they merge.
-
-6. In rare cases, we might decide that a PR should be closed without merging.
-  We'll make sure to provide clear reasoning when this happens.
-
-
-### Tips for Working on Packer
-
-#### Getting Your Pull Requests Merged Faster
-
-It is much easier to review pull requests that are:
-
-1. Well-documented: Try to explain in the pull request comments what your
-   change does, why you have made the change, and provide instructions for how
-   to produce the new behavior introduced in the pull request. If you can,
-   provide screen captures or terminal output to show what the changes look
-   like. This helps the reviewers understand and test the change.
-
-2. Small: Try to only make one change per pull request. If you found two bugs
-   and want to fix them both, that's _awesome_, but it's still best to submit
-   the fixes as separate pull requests. This makes it much easier for reviewers
-   to keep in their heads all of the implications of individual code changes,
-   and that means the PR takes less effort and energy to merge. In general, the
-   smaller the pull request, the sooner reviewers will be able to make time to
-   review it.
-
-3. Passing Tests: Based on how much time we have, we may not review pull
-   requests which aren't passing our tests. (Look below for advice on how to
-   run unit tests). If you need help figuring out why tests are failing, please
-   feel free to ask, but while we're happy to give guidance it is generally
-   your responsibility to make sure that tests are passing. If your pull request
-   changes an interface or invalidates an assumption that causes a bunch of
-   tests to fail, then you need to fix those tests before we can merge your PR.
-
-If we request changes, try to make those changes in a timely manner. Otherwise,
-PRs can go stale and be a lot more work for all of us to merge in the future.
-
-Even with everyone making their best effort to be responsive, it can be
-time-consuming to get a PR merged. It can be frustrating to deal with
-the back-and-forth as we make sure that we understand the changes fully. Please
-bear with us, and please know that we appreciate the time and energy you put
-into the project.
-
-#### Working on forks
-
-The easiest way to work on a fork is to set it as a remote of the Packer
-project. After following the steps in "Setting up Go to work on Packer":
-
-1. Navigate to the code:
-
-   `cd $GOPATH/src/github.com/hashicorp/packer`
-
-2. Add the remote by running:
-
-   `git remote add <name of remote> <github url of fork>`
-
-   For example:
-
-   `git remote add mwhooker https://github.com/mwhooker/packer.git`
-
-3. Checkout a feature branch:
-
-   `git checkout -b new-feature`
-
-4. Make changes.
-5. (Optional) Push your changes to the fork:
-
-   `git push -u <name of remote> new-feature`
-
-This way you can push to your fork to create a PR, but the code on disk still
-lives in the spot where the go cli tools are expecting to find it.
-
-#### Go modules & go vendor
-
-If you are submitting a change that requires new or updated dependencies,
-please include them in `go.mod`/`go.sum` and in the `vendor/` folder. This
-helps everything get tested properly in CI.
-
-Note that you will need to use [go
-mod](https://github.com/golang/go/wiki/Modules) to do this. This step is
-recommended but not required.
-
-Use `go get <project>` to add dependencies to the project and `go mod vendor`
-to make vendored copy of dependencies. See [go mod quick
-start](https://github.com/golang/go/wiki/Modules#quick-start) for examples.
-
-Please only apply the minimal vendor changes to get your PR to work. Packer
-does not attempt to track the latest version for each dependency.
-
-#### Running Unit Tests
-
-You can run tests for individual packages using commands like this:
-
-```
-make test TEST=./builder/amazon/...
-```
-
-#### Running Acceptance Tests
-
-Packer has [acceptance tests](https://en.wikipedia.org/wiki/Acceptance_testing)
-for various builders. These typically require an API key (AWS, GCE), or
-additional software to be installed on your computer (VirtualBox, VMware).
-
-If you're working on a new builder or builder feature and want to verify it is
-functioning (and also hasn't broken anything else), we recommend running the
-acceptance tests.
-
-**Warning:** The acceptance tests create/destroy/modify _real resources_, which
-may incur costs for real money. In the presence of a bug, it is possible that
-resources may be left behind, which can cost money even though you were not
-using them. We recommend running tests in an account used only for that purpose
-so it is easy to see if there are any dangling resources, and so production
-resources are not accidentally destroyed or overwritten during testing.
-
-To run the acceptance tests, invoke `make testacc`:
-
-```
-make testacc TEST=./builder/amazon/ebs
-...
-```
-
-The `TEST` variable lets you narrow the scope of the acceptance tests to a
-specific package / folder. The `TESTARGS` variable is recommended to filter down
-to a specific resource to test, since testing all of them at once can sometimes
-take a very long time.
-
-To run only a specific test, use the `-run` argument:
-
-```
-make testacc TEST=./builder/amazon/ebs TESTARGS="-run TestBuilderAcc_forceDeleteSnapshot"
-```
-
-Acceptance tests typically require other environment variables to be set for
-things such as API tokens and keys. Each test should error and tell you which
-credentials are missing, so those are not documented here.

+## Setting up Go to work on Packer
+
+If you have never worked with Go before, you will have to complete the
+following steps in order to be able to compile and test Packer. These instructions target POSIX-like environments (Mac OS X, Linux, Cygwin, etc.) so you may need to adjust them for Windows or other shells.
+
+1. [Download](https://golang.org/dl) and install Go. The instructions below
+   are for go 1.6. Earlier versions of Go are no longer supported.
+
+2. Set and export the `GOPATH` environment variable and update your `PATH`. For
+   example, you can add to your `.bash_profile`.
+
+    ```
+    export GOPATH=$HOME/go
+    export PATH=$PATH:$GOPATH/bin
+    ```
+
+3. Download the Packer source (and its dependencies) by running `go get
+   github.com/mitchellh/packer`. This will download the Packer source to
+   `$GOPATH/src/github.com/mitchellh/packer`.
+
+4. When working on packer `cd $GOPATH/src/github.com/mitchellh/packer` so you
+   can run `make` and easily access other files.
+
+5. Make your changes to the Packer source. You can run `make` in
+   `$GOPATH/src/github.com/mitchellh/packer` to run tests and build the packer
+   binary. Any compilation errors will be shown when the binaries are
+   rebuilding. If you don't have `make` you can simply run `go build -o bin/packer .` from the project root.
+
+6. After running building packer successfully, use
+   `$GOPATH/src/github.com/mitchellh/packer/bin/packer` to build a machine and
+   verify your changes work. For instance: `$GOPATH/src/github.com/mitchellh/packer/bin/packer build template.json`.
+
+7. If everything works well and the tests pass, run `go fmt` on your code
+   before submitting a pull-request.
+
+### Tips for Working on Packer
+
+#### Godeps
+
+If you are submitting a change that requires a change in dependencies, DO NOT update the `vendor/` folder. This keeps the PR smaller and easier to review. Instead, please indicate which upstream has changed and which version we should be using. You _may_ do this using `Godeps/Godeps.json` but this is not required.
+
+#### Running Unit Tests
+
+You can run tests for individual packages using commands like this:
+
+    $ make test TEST=./builder/amazon/...
+
+#### Running Acceptance Tests
+
+Packer has [acceptance tests](https://en.wikipedia.org/wiki/Acceptance_testing)
+for various builders. These typically require an API key (AWS, GCE), or
+additional software to be installed on your computer (VirtualBox, VMware).
+
+If you're working on a feature of a builder or a new builder and want verify it
+is functioning (and also hasn't broken anything else), we recommend running the
+acceptance tests.
+
+**Warning:** The acceptance tests create/destroy/modify *real resources*, which
+may incur real costs in some cases. In the presence of a bug, it is technically
+possible that broken backends could leave dangling data behind. Therefore,
+please run the acceptance tests at your own risk. At the very least, we
+recommend running them in their own private account for whatever builder you're
+testing.
+
+To run the acceptance tests, invoke `make testacc`:
+
+    $ make testacc TEST=./builder/amazon/ebs
+    ...
+
+The `TEST` variable lets you narrow the scope of the acceptance tests to a
+specific package / folder. The `TESTARGS` variable is recommended to filter
+down to a specific resource to test, since testing all of them at once can
+sometimes take a very long time.
+
+Acceptance tests typically require other environment variables to be set for
+things such as access keys. The test itself should error early and tell you
+what to set, so it is not documented here.

 Packer is a tool for building identical machine images for multiple platforms
 from a single source configuration.

 Packer is lightweight, runs on every major operating system, and is highly
 performant, creating machine images for multiple platforms in parallel. Packer
-comes out of the box with support for many platforms, the full list of which can
-be found at https://www.packer.io/docs/builders/index.html.

+* QEMU. Both KVM and Xen images.
+* VirtualBox

Sean Chittenden	489c75a363	Go's -X linker flag now requires only one argument (#3540 ) This fixes building `packer` with Go >1.6. From https://golang.org/cmd/link/: ``` -X importpath.name=value Set the value of the string variable in importpath named name to value. Note that before Go 1.5 this option took two separate arguments. Now it takes one argument split on the first = sign. ```	2016-09-20 16:34:30 -07:00
