-# **what?**
-# This workflow runs all integration tests for supported OS
-# and python versions and core adapters. If triggered by PR,
-# the workflow will only run tests for adapters related
-# to code changes. Use the `test all` and `test ${adapter}`
-# label to run all or additional tests. Use `ok to test`
-# label to mark PRs from forked repositories that are safe
-# to run integration tests for. Requires secrets to run
-# against different warehouses.
-
-# **why?**
-# This checks the functionality of dbt from a user's perspective
-# and attempts to catch functional regressions.
-
-# **when?**
-# This workflow will run on every push to a protected branch
-# and when manually triggered. It will also run for all PRs, including
-# PRs from forks. The workflow will be skipped until there is a label
-# to mark the PR as safe to run.

-The core function of dbt is SQL compilation and execution. Users create projects of dbt resources (models, tests, seeds, snapshots, ...), defined in SQL and YAML files, and they invoke dbt to create, update, or query associated views and tables. Today, dbt makes heavy use of Jinja2 to enable the templating of SQL, and to construct a DAG (Directed Acyclic Graph) from all of the resources in a project. Users can also extend their projects by installing resources (including Jinja macros) from other projects, called "packages."
-
-## dbt-core
-
-Most of the python code in the repository is within the `core/dbt` directory. Currently the main subdirectories are:
-
-- [`adapters`](core/dbt/adapters): Define base classes for behavior that is likely to differ across databases
-- [`clients`](core/dbt/clients): Interface with dependencies (agate, jinja) or across operating systems
-- [`config`](core/dbt/config): Reconcile user-supplied configuration from connection profiles, project files, and Jinja macros
-- [`context`](core/dbt/context): Build and expose dbt-specific Jinja functionality
-- [`contracts`](core/dbt/contracts): Define Python objects (dataclasses) that dbt expects to create and validate
-- [`deps`](core/dbt/deps): Package installation and dependency resolution
-- [`graph`](core/dbt/graph): Produce a `networkx` DAG of project resources, and selecting those resources given user-supplied criteria
-- [`include`](core/dbt/include): The dbt "global project," which defines default implementations of Jinja2 macros
-- [`parser`](core/dbt/parser): Read project files, validate, construct python objects
-- [`task`](core/dbt/task): Set forth the actions that dbt can perform when invoked
-
-### Invoking dbt
-
-The "tasks" map to top-level dbt commands. So `dbt run` => task.run.RunTask, etc. Some are more like abstract base classes (GraphRunnableTask, for example) but all the concrete types outside of task should map to tasks. Currently one executes at a time. The tasks kick off their “Runners” and those do execute in parallel. The parallelism is managed via a thread pool, in GraphRunnableTask.
-
-core/dbt/include/index.html
-This is the docs website code. It comes from the dbt-docs repository, and is generated when a release is packaged.
-
-## Adapters
-
-dbt uses an adapter-plugin pattern to extend support to different databases, warehouses, query engines, etc. For testing and development purposes, the dbt-postgres plugin lives alongside the dbt-core codebase, in the [`plugins`](plugins) subdirectory. Like other adapter plugins, it is a self-contained codebase and package that builds on top of dbt-core.
-
-Each adapter is a mix of python, Jinja2, and SQL. The adapter code also makes heavy use of Jinja2 to wrap modular chunks of SQL functionality, define default implementations, and allow plugins to override it.
-
-Each adapter plugin is a standalone python package that includes:
-
-- `dbt/include/[name]`: A "sub-global" dbt project, of YAML and SQL files, that reimplements Jinja macros to use the adapter's supported SQL syntax
-- `dbt/adapters/[name]`: Python modules that inherit, and optionally reimplement, the base adapter classes defined in dbt-core
-- `setup.py`
-
-The Postgres adapter code is the most central, and many of its implementations are used as the default defined in the dbt-core global project. The greater the distance of a data technology from Postgres, the more its adapter plugin may need to reimplement.
-
-## Testing dbt
-
-The [`test/`](test/) subdirectory includes unit and integration tests that run as continuous integration checks against open pull requests. Unit tests check mock inputs and outputs of specific python functions. Integration tests perform end-to-end dbt invocations against real adapters (Postgres, Redshift, Snowflake, BigQuery) and assert that the results match expectations. See [the contributing guide](CONTRIBUTING.md) for a step-by-step walkthrough of setting up a local development and testing environment.
-
-## Everything else
-
-- [docker](docker/): All dbt versions are published as Docker images on DockerHub. This subfolder contains the `Dockerfile` (constant) and `requirements.txt` (one for each version).
-- [etc](etc/): Images for README
-- [scripts](scripts/): Helper scripts for testing, releasing, and producing JSON schemas. These are not included in distributions of dbt, not are they rigorously tested—they're just handy tools for the dbt maintainers :)

In many cases, community members will chime in with their own thoughts on the problem statement. If you as the issue creator are interested in submitting a Pull Request to address the issue, you should indicate this in the body of the issue. The `dbt` maintainers are _always_ happy to help contributors with the implementation of fixes and features, so please also indicate if there's anything you're unsure about or could use guidance around in the issue.

 ### Submitting a change
 
-If an issue is appropriately well scoped and describes a beneficial change to the `dbt` codebase, then anyone may submit a Pull Request to implement the functionality described in the issue. See the sections below on how to do this.

-The `dbt` maintainers will add a `good first issue` label if an issue is suitable for a first-time contributor. This label often means that the required code change is small, limited to one database adapter, or a net-new addition that does not impact existing functionality. You can see the list of currently open issues on the [Contribute](https://github.com/dbt-labs/dbt-core/contribute) page.

 Here's a good workflow:
 - Comment on the open issue, expressing your interest in contributing the required code change
 - Outline your planned implementation. If you want help getting started, ask!
-- Follow the steps outlined below to develop locally. Once you have opened a PR, one of the `dbt` maintainers will work with you to review your code.
-- Add a test! Tests are crucial for both fixes and new features alike. We want to make sure that code works as intended, and that it avoids any bugs  previously encountered. Currently, the best resource for understanding `dbt`'s [unit](test/unit) and [integration](test/integration) tests is the tests themselves. One of the maintainers can help by pointing out relevant examples.

-In some cases, the right resolution to an open issue might be tangential to the `dbt` codebase. The right path forward might be a documentation update or a change that can be made in user-space. In other cases, the issue might describe functionality that the `dbt` maintainers are unwilling or unable to incorporate into the `dbt` codebase. When it is determined that an open issue describes functionality that will not translate to a code change in the `dbt` repository, the issue will be tagged with the `wontfix` label (see below) and closed.

 ### Using issue labels
 
-The `dbt` maintainers use labels to categorize open issues. Some labels indicate the databases impacted by the issue, while others describe the domain in the `dbt` codebase germane to the discussion. While most of these labels are self-explanatory (eg. `snowflake` or `bigquery`), there are others that are worth describing.

-#### Branching Strategy
-
-`dbt` has three types of branches:
-
-- **Trunks** are where active development of the next release takes place. There is one trunk named `develop` at the time of writing this, and will be the default branch of the repository.
-- **Release Branches** track a specific, not yet complete release of `dbt`. Each minor version release has a corresponding release branch. For example, the `0.11.x` series of releases has a branch called `0.11.latest`. This allows us to release new patch versions under `0.11` without necessarily needing to pull them into the latest version of `dbt`.
-- **Feature Branches** track individual features and fixes. On completion they should be merged into the trunk branch or a specific release branch.

+Getting the dbt integration tests set up in your local environment will be very helpful as you start to make changes to your local version of dbt. The section that follows outlines some helpful tips for setting up the test environment.
 
-Although `dbt` works with a number of different databases, you won't need to supply credentials for every one of these databases in your test environment. Instead you can test all dbt-core code changes with Python and Postgres.
+### Running tests via Docker
 
-### Initial setup
+dbt's unit and integration tests run in Docker. Because dbt works with a number of different databases, you will need to supply credentials for one or more of these databases in your test environment. Most organizations don't have access to each of a BigQuery, Redshift, Snowflake, and Postgres database, so it's likely that you will be unable to run every integration test locally. Fortunately, Fishtown Analytics provides a CI environment with access to sandboxed Redshift, Snowflake, BigQuery, and Postgres databases. See the section on [_Submitting a Pull Request_](#submitting-a-pull-request) below for more information on this CI setup.
 
-We recommend starting with `dbt`'s Postgres tests. These tests cover most of the functionality in `dbt`, are the fastest to run, and are the easiest to set up. To run the Postgres integration tests, you'll have to do one extra step of setting up the test database:
 
-```sh
-make setup-db
+### Specifying your test credentials
+
+dbt uses test credentials specified in a `test.env` file in the root of the repository. This `test.env` file is git-ignored, but please be _extra_ careful to never check in credentials or other sensitive information when developing against dbt. To create your `test.env` file, copy the provided sample file, then supply your relevant credentials:
+
+```
+cp test.env.sample test.env
+atom test.env # supply your credentials
+```
+
+We recommend starting with dbt's Postgres tests. These tests cover most of the functionality in dbt, are the fastest to run, and are the easiest to set up. dbt's test suite runs Postgres in a Docker container, so no setup should be required to run these tests.
+
+If you additionally want to test Snowflake, Bigquery, or Redshift, locally you'll need to get credentials and add them to the `test.env` file. In general, it's most important to have successful unit and Postgres tests. Once you open a PR, dbt will automatically run integration tests for the other three core database adapters. Of course, if you are a BigQuery user, contributing a BigQuery-only feature, it's important to run BigQuery tests as well.
+
+### Test commands
+
+dbt's unit tests and Python linter can be run with:
+
+```
+make test-unit
+```
+
+To run the Postgres + Python 3.6 integration tests, you'll have to do one extra step of setting up the test database:
+
 ```
-or, alternatively:
-```sh
 docker-compose up -d database
 PGHOST=localhost PGUSER=root PGPASSWORD=password PGDATABASE=postgres bash test/setup_db.sh
 ```

To create your `test.env` file, copy the provided sample file, then supply your relevant credentials. This step is only required to use non-Postgres databases.
+To run a quick test for Python3 integration tests on Postgres, you can run:

-### Test commands
-
-There are a few methods for running tests locally.
-
-#### Makefile
-
-There are multiple targets in the Makefile to run common test suites and code
-checks, most notably:
-
-```sh
-# Runs unit tests with py38 and code checks in parallel.
-make test
-# Runs postgres integration tests with py38 in "fail fast" mode.
-make integration
+To run tests for a specific database, invoke `tox` directly with the required flags:
 ```
-> These make targets assume you have a recent version of [`tox`](https://tox.readthedocs.io/en/latest/) installed locally,
-> unless you use choose a Docker container to run tests. Run `make help` for more info.
+# Run Postgres py36 tests
+docker-compose run test tox -e integration-postgres-py36 -- -x
 
-Check out the other targets in the Makefile to see other commonly used test
-suites.
+# Run Snowflake py36 tests
+docker-compose run test tox -e integration-snowflake-py36 -- -x
 
-#### `tox`
+# Run BigQuery py36 tests
+docker-compose run test tox -e integration-bigquery-py36 -- -x
 
-[`tox`](https://tox.readthedocs.io/en/latest/) takes care of managing virtualenvs and install dependencies in order to run
-tests. You can also run tests in parallel, for example, you can run unit tests
-for Python 3.6, Python 3.7, Python 3.8, `flake8` checks, and `mypy` checks in
-parallel with `tox -p`. Also, you can run unit tests for specific python versions
-with `tox -e py36`. The configuration for these tests in located in `tox.ini`.
-
-#### `pytest`
-
-Finally, you can also run a specific test or group of tests using [`pytest`](https://docs.pytest.org/en/latest/) directly. With a virtualenv
-active and dev dependencies installed you can do things like:
-```sh
-# run specific postgres integration tests
-python -m pytest -m profile_postgres test/integration/001_simple_copy_test
-# run all unit tests in a file
-python -m pytest test/unit/test_graph.py
-# run a specific unit test
-python -m pytest test/unit/test_graph.py::GraphTest::test__dependency_list
+# Run Redshift py36 tests
+docker-compose run test tox -e integration-redshift-py36 -- -x
 ```
-> [Here](https://docs.pytest.org/en/reorganize-docs/new-docs/user/commandlineuseful.html)
-> is a list of useful command-line options for `pytest` to use while developing.
+
+To run a specific test by itself:
+```
+docker-compose run test tox -e explicit-py36 -- -s -x -m profile_{adapter} {path_to_test_file_or_folder}
+```
+E.g.
+```
+docker-compose run test tox -e explicit-py36 -- -s -x -m profile_snowflake test/integration/001_simple_copy_test
+```
+
+See the `Makefile` contents for more some other examples of ways to run `tox`.

RELEASE.md

@@ -0,0 +1,92 @@
+### Release Procedure :shipit:
+
+#### Branching Strategy
+
+dbt has three types of branches:
+
+- **Trunks** track the latest release of a minor version of dbt. Historically, we used the `master` branch as the trunk. Each minor version release has a corresponding trunk. For example, the `0.11.x` series of releases has a branch called `0.11.latest`. This allows us to release new patch versions under `0.11` without necessarily needing to pull them into the latest version of dbt.
+- **Release Branches** track a specific, not yet complete release of dbt. These releases are codenamed since we don't always know what their semantic version will be. Example: `dev/lucretia-mott` became `0.11.1`.
+- **Feature Branches** track individual features and fixes. On completion they should be merged into a release branch.
+
+#### Git & PyPI
+
+1. Update CHANGELOG.md with the most recent changes
+2. If this is a release candidate, you want to create it off of your release branch. If it's an actual release, you must first merge to a master branch. Open a Pull Request in Github to merge it into the appropriate trunk (`X.X.latest`)
+3. Bump the version using `bumpversion`:
+  - Dry run first by running `bumpversion --new-version <desired-version> <part>` and checking the diff. If it looks correct, clean up the chanages and move on:
+  - Alpha releases: `bumpversion --commit --no-tag --new-version 0.10.2a1 num`
+  - Patch releases: `bumpversion --commit --no-tag --new-version 0.10.2 patch`
+  - Minor releases: `bumpversion --commit --no-tag --new-version 0.11.0 minor`
+  - Major releases: `bumpversion --commit --no-tag --new-version 1.0.0 major`
+4. (If this is a not a release candidate) Merge to `x.x.latest` and (optionally) `master`.
+5. Update the default branch to the next dev release branch.
+6. Build source distributions for all packages by running `./scripts/build-sdists.sh`. Note that this will clean out your `dist/` folder, so if you have important stuff in there, don't run it!!!
+7. Deploy to pypi
+  - `twine upload dist/*`
+8. Deploy to homebrew (see below)
+9. Deploy to conda-forge (see below)
+10. Git release notes (points to changelog)
+11. Post to slack (point to changelog)
+
+After releasing a new version, it's important to merge the changes back into the other outstanding release branches. This avoids merge conflicts moving forward.
+
+In some cases, where the branches have diverged wildly, it's ok to skip this step. But this means that the changes you just released won't be included in future releases.
+
+#### Homebrew Release Process
+
+1. Clone the `homebrew-dbt` repository:
+
+```
+git clone git@github.com:fishtown-analytics/homebrew-dbt.git
+```
+
+2. For ALL releases (prereleases and version releases), copy the relevant formula. To copy from the latest version release of dbt, do:
+
+```bash
+cp Formula/dbt.rb Formula/dbt@{NEW-VERSION}.rb
+```
+
+To copy from a different version, simply copy the corresponding file.
+
+3. Open the file, and edit the following:
+- the name of the ruby class: this is important, homebrew won't function properly if the class name is wrong. Check historical versions to figure out the right name.
+- under the `bottle` section, remove all of the hashes (lines starting with `sha256`)
+
+4. Create a **Python 3.7** virtualenv, activate it, and then install two packages: `homebrew-pypi-poet`, and the version of dbt you are preparing. I use:
+
+```
+pyenv virtualenv 3.7.0 homebrew-dbt-{VERSION}
+pyenv activate homebrew-dbt-{VERSION}
+pip install dbt=={VERSION} homebrew-pypi-poet
+```
+
+homebrew-pypi-poet is a program that generates a valid homebrew formula for an installed pip package. You want to use it to generate a diff against the existing formula. Then you want to apply the diff for the dependency packages only -- e.g. it will tell you that `google-api-core` has been updated and that you need to use the latest version.
+
+5. reinstall, test, and audit dbt. if the test or audit fails, fix the formula with step 1.
+
+```bash
+brew uninstall --force Formula/{YOUR-FILE}.rb
+brew install Formula/{YOUR-FILE}.rb
+brew test dbt
+brew audit --strict dbt
+```
+
+6. Ask Connor to bottle the change (only his laptop can do it!)
+
+#### Conda Forge Release Process
+
+1. Clone the fork of `conda-forge/dbt-feedstock` [here](https://github.com/fishtown-analytics/dbt-feedstock)
+```bash
+git clone git@github.com:fishtown-analytics/dbt-feedstock.git
+
+```
+2. Update the version and sha256 in `recipe/meta.yml`. To calculate the sha256, run:
+
+```bash
+wget https://github.com/fishtown-analytics/dbt/archive/v{version}.tar.gz
+openssl sha256 v{version}.tar.gz
+```
+
+3. Push the changes and create a PR against `conda-forge/dbt-feedstock`
+
+4. Confirm that all automated conda-forge tests are passing

-# Events Module
-
-The Events module is the implmentation for structured logging. These events represent both a programatic interface to dbt processes as well as human-readable messaging in one centralized place. The centralization allows for leveraging mypy to enforce interface invariants across all dbt events, and the distinct type layer allows for decoupling events and libraries such as loggers.
-
-# Using the Events Module
-The event module provides types that represent what is happening in dbt in `events.types`. These types are intended to represent an exhaustive list of all things happening within dbt that will need to be logged, streamed, or printed. To fire an event, `events.functions::fire_event` is the entry point to the module from everywhere in dbt.
-
-# Adding a New Event
-In `events.types` add a new class that represents the new event. This may be a simple class with no values, or it may be a dataclass with some values to construct downstream messaging. Only include the data necessary to construct this message within this class. You must extend all destinations (e.g. - if your log message belongs on the cli, extend `CliEventABC`) as well as the loglevel this event belongs to.
