Address: #2198 (review) This pull request adds a test to verify that profile metrics are correctly handled when dealing with non-Cosmos operators. The test ensures that when `_build_task_metrics` is called on a task instance with a regular Airflow operator (not a dbt/Cosmos operator), the profile-related metrics return appropriate `None` values. **Key changes:** - Added a `DummyOperator` class that extends `BaseOperator` without Cosmos-specific functionality - Added `test_profile_metrics_with_non_cosmos_operator()` to validate metrics behavior with non-Cosmos operators
…2214) Related to: #2141 This PR updates the documentation to reflect that dataset emission is now supported in `ExecutionMode.AIRFLOW_ASYNC` since Cosmos 1.12.0. The limitation that prevented dataset events from being emitted in async mode has been resolved. - Removes the documented limitation about dataset events not being emitted in AIRFLOW_ASYNC mode - Updates documentation to include AIRFLOW_ASYNC in the list of execution modes supporting the `emit_datasets` feature
The PR fixes default values in the documentation for `models_relative_path`, `seeds_relative_path` and `snapshots_relative_path`. Current values are taken from: https://github.com/astronomer/astronomer-cosmos/blob/975ebae2b4c6ef75dd442678fb538771bc717829/cosmos/config.py#L166-L168 Before changes: <img width="1128" height="457" alt="image" src="https://github.com/user-attachments/assets/a6bad9b5-c508-48e6-b3fc-3a27ff9a1bfb" /> After changes: <img width="1126" height="457" alt="image" src="https://github.com/user-attachments/assets/9b0be6e8-a88f-4dca-b6f7-24794664c46e" />
## Description Fix minor typo in the documentation.
When using ExecutionMode.WATCHER with InvocationMode.SUBPROCESS, the _process_log_line_callable was being incorrectly bound as a method when accessed through an instance. This caused Python's descriptor protocol to pass 'self' as the first argument, resulting in: TypeError: _store_dbt_resource_status_from_log() takes 2 positional arguments but 3 were given The fix wraps the function with staticmethod() to prevent binding when accessed via self._process_log_line_callable. Also adds comprehensive tests for the _store_dbt_resource_status_from_log function and verifies the callable is not bound as a method. closes: #2224
`DbtSourceWatcherOperator` should inherit `template_fields` from its parent `DbtSourceLocalOperator` instead of `DbtConsumerWatcherSensor`. The previous assignment incorrectly included fields like `model_unique_id` that do not exist on source operators, causing `AttributeError` when using sources with tests in `ExecutionMode.WATCHER` with `SourceRenderingBehavior.WITH_TESTS_OR_FRESHNESS`. closes: #2203
✅ Deploy Preview for astronomer-cosmos canceled.

Cosmos main branch Python 2.6 tests started failing, as observed while
testing Python 3.10, AF 2.6 and dbt 1.11:
```

The issue seemed to be conflicting dependencies, particularly the
installation of "httplib2==0.30.0" (failure) instead of
"httplib2==0.31.0" (success)
Example of success after this change:

(cherry picked from commit dbaef2c)
Make our configuration validation more robust, to guide users when they misconfigure Cosmos `RenderConfig.invocation_mode`. This configuration should only be used if dbt is installed in the same Python virtualenv as Cosmos. Recently, I observed a customer incorrectly configuring Cosmos as follows: ``` ExecutionConfig( dbt_executable_path=airflowHome + '/dbt_venv/bin/dbt', execution_mode=ExecutionMode.WATCHER, invocation_mode=InvocationMode.DBT_RUNNER ) ``` Which led to the error: ``` ModuleNotFoundError: No module named 'dbt' ``` This was raised in Cosmos 1.12, when trying to resolve `dbt.version` ``` cosmos/operators/watcher.py:_fallback_to_local_run → build_and_run_cmd → _generate_dbt_flags ``` (cherry picked from commit 4cfac69)
