Code Review
This pull request standardizes the 'CONTRIBUTING.rst' files across the monorepo by centralizing the guidelines and pointing to a root-level document. A minor issue was identified in the main 'CONTRIBUTING.rst' file where a link target was incorrectly defined, which would cause documentation build errors. The reviewer provided a correction for this link target.

## The Problem Two unit tests in `google-cloud-bigquery` (`test_result_w_retry_wo_state` and `test_result_w_custom_retry`) were failing intermittently with a `TimeoutError` or `RetryError`. This flakiness occurs because the tests use a very short inner retry deadline of 0.1 seconds. Under heavy load (such as during parallel testing or on constrained continuous integration runners), this deadline can be exceeded, causing the test to fail confusingly. ## The Solution Increased the `deadline` parameter for the custom retry objects in both tests from 0.1 seconds to 1.0 seconds. This provides enough buffer for the test assertions to complete without timing out, aligning with other similar tests in the suite. ## Notes to Reviewers - This change only affects unit tests and does not alter production code. - This issue is blocking: - #17642 - #17608 Here is a snippet of the failure: ```python def test_result_w_retry_wo_state(global_time_lock): from google.cloud.bigquery.retry import DEFAULT_GET_JOB_TIMEOUT begun_job_resource = helpers._make_job_resource( job_id=JOB_ID, project_id=PROJECT, location="EU", started=True ) done_job_resource = helpers._make_job_resource( job_id=JOB_ID, project_id=PROJECT, location="EU", started=True, ended=True, ) conn = helpers.make_connection( exceptions.NotFound("not normally retriable"), begun_job_resource, exceptions.NotFound("not normally retriable"), done_job_resource, ) client = helpers._make_client(project=PROJECT, connection=conn) job = google.cloud.bigquery.job._AsyncJob( google.cloud.bigquery.job._JobReference(JOB_ID, PROJECT, "EU"), client ) custom_predicate = mock.Mock() custom_predicate.return_value = True custom_retry = google.api_core.retry.Retry( predicate=custom_predicate, initial=0.001, maximum=0.001, deadline=0.1, ) > assert job.result(retry=custom_retry) is job ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ tests/unit/job/test_async_job_retry.py:115: _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ google/cloud/bigquery/job/base.py:1047: in result return super(_AsyncJob, self).result(timeout=timeout, retry=retry) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ .nox/unit-3-12-test_type-unit/lib/python3.12/site-packages/google/api_core/future/polling.py:256: in result self._blocking_poll(timeout=timeout, retry=retry, polling=polling) _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ self = _AsyncJob<project=test-project, location=EU, id=test-job-id> timeout = None retry = <google.api_core.retry.retry_unary.Retry object at 0x7ff2beda32c0> polling = <google.api_core.retry.retry_unary.Retry object at 0x7ff2beda01d0> def _blocking_poll(self, timeout=_DEFAULT_VALUE, retry=None, polling=None): """Poll and wait for the Future to be resolved.""" if self._result_set: return polling = polling or self._polling if timeout is not PollingFuture._DEFAULT_VALUE: polling = polling.with_timeout(timeout) try: polling(self._done_or_raise)(retry=retry) except exceptions.RetryError: > raise concurrent.futures.TimeoutError( f"Operation did not complete within the designated timeout of " f"{polling.timeout} seconds." ) E TimeoutError: Operation did not complete within the designated timeout of None seconds. ```
