This article addresses the issue where git pull may fail to fully synchronize code from a remote repository during server deployments. By examining a common scenario—local uncommitted changes preventing complete pulls—it delves into the merge mechanism of git pull and its limitations. The core solution involves using git fetch combined with git reset --hard to forcibly reset the local workspace to a remote commit, ensuring deployment environments match the code repository exactly. Detailed steps, code examples, and best practices are provided to help developers avoid common pitfalls in deployment workflows.
