Summary of Changes

Hello @parthea, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request implements an automated fix to resolve documentation build failures for the google-shopping-merchant-accounts client library. It introduces a post-processing rule to temporarily prevent documentation warnings from being treated as errors, specifically targeting an external formatting issue in google/protobuf/empty.proto. This ensures that the documentation can be generated successfully without being blocked by warnings from an external dependency.

Highlights

• Documentation Build Fix: The pull request introduces a change to allow documentation builds for the google-shopping-merchant-accounts client library to pass, specifically by disabling the treatment of warnings as errors during the sphinx-build process.
• Root Cause Addressed: This modification addresses a known formatting issue originating from google/protobuf/empty.proto which was causing documentation warnings and subsequently failing builds when warnings were treated as errors.
• Automated Generation: The changes, including the addition of a post-processing configuration and the update to the noxfile.py, were automatically generated by the librarian tool.

Code Review

This automated pull request disables the 'warnings as errors' setting for the documentation build of the google-shopping-merchant-accounts package. This change is a necessary workaround for a build failure caused by an upstream issue. While the change is acceptable to unblock the build, I have added a comment suggesting a more targeted, long-term solution to avoid suppressing all future documentation warnings.

[gemini-code-assist]

While removing the -W flag resolves the immediate build failure caused by the upstream issue, it has the side effect of allowing all future documentation warnings to pass silently. This could mask new issues and lead to a decline in documentation quality over time.

A more targeted approach would be to suppress only the specific "Unexpected indentation" warning. This can typically be achieved in the Sphinx conf.py file using the suppress_warnings configuration.

If modifying conf.py is not feasible within the current generator setup, this change is an acceptable workaround. However, it would be beneficial to create a follow-up issue to track implementing a more targeted suppression or to remove this workaround once the upstream issue is resolved.

This is only a temporary workaround until googleapis/gapic-generator-python#2490 can be addressed.
