Greptile Overview

Greptile Summary

Updated build checkpoint strings to match new Vite output format and modified checkpoint matching logic to handle multiple checkpoints per line.

• Updated checkpoint strings in reflex/utils/build.py from old format ("building for production", "building SSR bundle for production") to new Vite format ("building client environment for production...", "modules transformed", "building ssr environment for production...")
• Modified show_progress function in reflex/utils/processes.py to use a while loop that allows matching multiple checkpoints in a single log line
• Found a logic bug: after all checkpoints are matched, the function continues processing all remaining log lines instead of breaking early, which wastes processing time

Confidence Score: 3/5

• This PR is mostly safe but contains a logic bug that causes unnecessary log processing
• The checkpoint string updates are correct and necessary for the new Vite output format. However, the refactored checkpoint matching logic contains a bug where the function doesn't break from the outer for loop after all checkpoints are matched, causing it to continue processing all remaining log lines unnecessarily. While this doesn't break functionality, it's inefficient and deviates from the original behavior.
• Pay close attention to reflex/utils/processes.py - the logic change needs the missing break statement after the while loop
