Code Review

This pull request introduces a new shell script, promote_from_production_to_production_050.sh, to automate a 50% staged rollout for Android production releases. The review feedback focuses on improving script robustness and CI compatibility, specifically suggesting that skip conditions should return a success exit code (0) rather than an error (1) to avoid unnecessary pipeline failures. Additionally, the reviewer recommends double-quoting variable expansions to prevent word splitting and ensure consistent shell script execution.

Code Review

This pull request improves the robustness and consistency of various shell scripts by quoting variables like $GIT_PROJECT_NAME and ${SCRIPT_DIR} to prevent word splitting and globbing issues. It also standardizes the formatting of promote.sh and publish.sh command calls across the Android deployment scripts and introduces a new script for a 50% production rollout. Feedback was provided regarding inconsistent formatting in the 100% production promotion script to ensure it aligns with the structure used in other rollout scripts.

Pull request overview

Adds a new Play Store promotion helper script to ramp Production-to-Production rollouts to 50%, and standardizes quoting/formatting across existing bash release/promote scripts (especially for “old repo” *-gradle detection).

Changes:

• Add promote_from_production_to_production_050.sh to promote Production → Production with --user-fraction 0.50.
• Quote "$GIT_PROJECT_NAME" consistently in [[ ... == *"-gradle"* ]] checks.
• Reformat several publish.sh / promote.sh wrapper invocations into multi-line commands for readability.
