Code Review
This pull request automates the migration of gsutil commands to the more modern gcloud storage commands across several Jupyter notebooks. The automated changes are largely correct, but I've identified a recurring issue in two of the notebooks. The logic for parsing the output of gcloud storage ls is flawed due to case-sensitivity differences from the old gsutil command, which will lead to runtime errors. I have provided specific code suggestions to fix these issues, ensuring the notebooks will run as expected after the migration.

The output format of gcloud storage ls --full --buckets differs from gsutil ls -Lb. Specifically, gcloud uses "Location Constraint:" (title case), while the grep command is searching for the lowercase "Location constraint:". This case-sensitivity will cause the grep to fail, leading to a runtime error when the script attempts to access shell_output[0]. To make this command more robust, I recommend using a case-insensitive grep and an improved sed command to correctly parse the output.
shell_output = ! gcloud storage ls --full --buckets {BUCKET_NAME} | grep -i "Location constraint:" | sed -E "s/Location constraint: *//i"\n
| " shell_output = ! gsutil ls -Lb {BUCKET_NAME} | grep \"Location constraint:\" | sed \"s/Location constraint://\"\n", | ||
| " bucket_region = shell_output[0].strip().lower()\n", | ||
| " # Note: The format of the full listing output is different. gcloud storage uses a title case for keys and will not display a field if its value is \"None\".\n", | ||

Automated: Migrate paths from gsutil to gcloud storage
This CL is part of the on going effort to migrate from the legacy
gsutiltool to the new and improvedgcloud storagecommand-line interface.gcloud storageis the recommended and modern tool for interacting with Google Cloud Storage, offering better performance, unified authentication, and a more consistent command structure with othergcloudcomponents. 🚀Automation Details
This change was generated automatically by an agent that targets users of
gsutil.The transformations applied are based on the gsutil to gcloud storage migration guide.
While we have based the automation on the migration guide, every use case is unique.
It is crucial that you thoroughly test these changes in environments appropriate to your use-case before merging.
Be aware of potential differences between
gsutilandgcloud storagethat could impact your workflows.For instance, the structure of command output may have changed, requiring updates to any scripts that parse it. Similarly, command behavior can differ subtly; the
gcloud storage rsynccommand has a different file deletion logic thangsutil rsync, which could lead to unintended file deletions.Our migration guides can help guide you through a list of mappings and some notable differences between the two tools.
Standard presubmit tests are run as part of this CL's workflow. If you need to target an additional test workflow or require assistance with testing, please let us know.
Please verify that all your Cloud Storage operations continue to work as expected to avoid any potential disruptions in production.
