+
+### Breaking Changes
+
+- Allow `--select` and `--exclude` multiple times ([#7158](https://github.com/dbt-labs/dbt-core/issues/7158))
+- Specifying "log-path" and "target-path" in "dbt_project.yml" is deprecated. This functionality will be removed in a future version of dbt-core. If you need to specify a custom path for logs or artifacts, please set via CLI flag or env var instead. ([#6882](https://github.com/dbt-labs/dbt-core/issues/6882))

+# **what?**
+# This workflow will test all test(s) at the input path given number of times to determine if it's flaky or not.  You can test with any supported OS/Python combination.
+# This is batched in 10 to allow more test iterations faster.
+
+# **why?**
+# Testing if a test is flaky and if a previously flaky test has been fixed.  This allows easy testing on supported python versions and OS combinations.
+
+# **when?**

+# Exception Handling
+
+## `requires.py`
+
+### `postflight`
+In the postflight decorator, the click command is invoked (i.e. `func(*args, **kwargs)`) and wrapped in a `try/except` block to handle any exceptions thrown.
+Any exceptions thrown from `postflight` are wrapped by custom exceptions from the `dbt.cli.exceptions` module (i.e. `ResultExit`, `ExceptionExit`) to instruct click to complete execution with a particular exit code.
+
+Some `dbt-core` handled exceptions have an attribute named `results` which contains results from running nodes (e.g. `FailFastError`). These are wrapped in the `ResultExit` exception to represent runs that have failed in a way that `dbt-core` expects.
+If the invocation of the command does not throw any exceptions but does not succeed, `postflight` will still raise the `ResultExit` exception to make use of the exit code.
+These exceptions produce an exit code of `1`.
+
+Exceptions wrapped with `ExceptionExit` may be thrown by `dbt-core` intentionally (i.e. an exception that inherits from `dbt.exceptions.Exception`) or unintentionally (i.e. exceptions thrown by the python runtime). In either case these are considered errors that `dbt-core` did not expect and are treated as genuine exceptions.
+These exceptions produce an exit code of `2`.
+
+If no exceptions are thrown from invoking the command and the command succeeds, `postflight` will not raise any exceptions.
+When no exceptions are raised an exit code of `0` is produced.
+
+## `main.py`
+
+### `dbtRunner`
+`dbtRunner` provides a programmatic interface for our click CLI and wraps the invocation of the click commands to handle any exceptions thrown.
+
+`dbtRunner.invoke` should ideally only ever return an instantiated `dbtRunnerResult` which contains the following fields:
+- `success`: A boolean representing whether the command invocation was successful
+- `result`: The optional result of the command invoked. This attribute can have many types, please see the definition of `dbtRunnerResult` for more information
+- `exception`: If an exception was thrown during command invocation it will be saved here, otherwise it will be `None`. Please note that the exceptions held in this attribute are not the exceptions thrown by `preflight` but instead the exceptions that `ResultExit` and `ExceptionExit` wrap
+
+Programmatic exception handling might look like the following:
+```python
+res = dbtRunner().invoke(["run"])

+
+## `dbt/tests/util.py`
+
+### `run_dbt`
+In many of our functional and integration tests, we want to be sure that an invocation of `dbt` raises a certain exception.
+A common pattern for these assertions:
+```python
+class TestSomething:
+    def test_something(self, project):
+        with pytest.raises(SomeException):
+            run_dbt(["run"])
+```
+To allow these tests to assert that exceptions have been thrown, the `run_dbt` function will raise any exceptions it recieves from the invocation of a `dbt` command.

 ============================
+How to invoke dbt commands in python runtime
+--------------------------------------------
+
+Right now the best way to invoke a command from python runtime is to use the `dbtRunner` we exposed
+
+.. code-block:: python
+
+    from dbt.cli.main import dbtRunner
+    cli_args = ['run', '--project-dir', 'jaffle_shop']
+
+    # initialize the dbt runner
+    dbt = dbtRunner()
+    # run the command
+    res, success = dbt.invoke(args)
+
+You can also pass in pre constructed object into dbtRunner, and we will use those objects instead of loading up from the disk.
+
+.. code-block:: python
+
+    # preload profile and project
+    profile = load_profile(project_dir, {}, 'testing-postgres')
+    project = load_project(project_dir, False, profile, {})
+
+    # initialize the runner with pre-loaded profile and project
+    dbt = dbtRunner(profile=profile, project=project)
+    # run the command, this will use the pre-loaded profile and project instead of loading
+    res, success = dbt.invoke(cli_args)
+
+
+For the full example code, you can refer to `core/dbt/cli/example.py`

 ============================
+Programmatic invocations
+--------------------------------------------
+
+In v1.5, dbt-core added support for programmatic invocations. The intent of this entry point is provide **exact parity** with CLI functionality, callable from within a Python script or application.
+
+The main entry point is a ``dbtRunner`` class that wraps around ``dbt-core``'s CLI, and allows you to "invoke" CLI commands as Python methods. Each command returns a `dbtRunnerResult` object, which has three attributes:
+
+* ``success`` (bool): Whether the command succeeded.
+* ``result``: If the command completed (successfully or with handled errors), its result(s). Return type varies by command.
+* ``exception``: If the dbt invocation encountered an unhandled error and did not complete, the exception it encountered.
+
+.. code-block:: python
+
+    from dbt.cli.main import dbtRunner, dbtRunnerResult
+
+    # initialize
+    dbt = dbtRunner()
+
+    # create CLI args as a list of strings
+    cli_args = ["run", "--select", "tag:my_tag"]
+
+    # run the command
+    res: dbtRunnerResult = dbt.invoke(cli_args)
+
+    # inspect the results
+    for r in res.result:
+        print(f"{r.node.name}: {r.status}")
+

 When events are processed via `fire_event`, nearly everything is logged. Whether or not the user has enabled the debug flag, all debug messages are still logged to the file. However, some events are particularly time consuming to construct because they return a huge amount of data. Today, the only messages in this category are cache events and are only logged if the `--log-cache-events` flag is on. This is important because these messages should not be created unless they are going to be logged, because they cause a noticable performance degredation. These events use a "fire_event_if" functions.

 # Adding a New Event
-* Add a new message in types.proto with an EventInfo field first
-* run the protoc compiler to update proto_types.py:  ```protoc --python_betterproto_out . types.proto```
-* Add a wrapping class in core/dbt/event/types.py with a Level superclass and the superclass from proto_types.py, plus code and message methods
+* Add a new message in types.proto, and a second message with the same name + "Msg". The "Msg" message should have two fields, an "info" field of EventInfo, and a "data" field referring to the message name without "Msg"
+* run the protoc compiler to update types_pb2.py:   make proto_types
+* Add a wrapping class in core/dbt/event/types.py with a Level superclass  plus code and message methods
 * Add the class to tests/unit/test_events.py

-Note that no attributes can exist in these event classes except for fields defined in the protobuf definitions, because the betterproto metaclass will throw an error. Betterproto provides a to_dict() method to convert the generated classes to a dictionary and from that to json. However some attributes will successfully convert to dictionaries but not to serialized protobufs, so we need to test both output formats.
+We have switched from using betterproto to using google protobuf, because of a lack of support for Struct fields in betterproto.

+The google protobuf interface is janky and very much non-Pythonic. The "generated" classes in types_pb2.py do not resemble regular Python classes. They do not have normal constructors; they can only be constructed empty. They can be "filled" by setting fields individually or using a json_format method like ParseDict.  We have wrapped the logging events with a class (in types.py) which allows using a constructor -- keywords only, no positional parameters.
