1. Repository Synchronization Failures
Understanding the Issue
Users experience failures when synchronizing repositories, leading to incomplete updates or missing changes.
Root Causes
- Network connectivity issues.
- Authentication failures when pushing or pulling changes.
- Incorrect repository configuration or permissions.
Fix
Check network connectivity:
ping plastic-server
Ensure the user has the correct permissions:
cm whoami
Force synchronization if changes are stuck:
cm sync repo-name@server:port
2. Merge Conflicts
Understanding the Issue
Merge conflicts occur when multiple users modify the same file, requiring manual resolution.
Root Causes
- Concurrent edits on the same file.
- Branching strategy leading to frequent conflicts.
- Incorrect merge tool configuration.
Fix
Use the Plastic SCM merge tool to resolve conflicts:
cm resolve
Rebase changes before merging:
cm rebase br:/main br:/feature
Configure an external merge tool:
cm setmergetool --mergetool=BeyondCompare
3. Authentication Problems
Understanding the Issue
Users are unable to log in or authenticate with the Plastic SCM server.
Root Causes
- Incorrect user credentials.
- Expired or missing authentication tokens.
- LDAP or Active Directory misconfiguration.
Fix
Reset user credentials:
cm chpasswd user-name
Verify token authentication:
cm token
Restart the authentication service:
sudo systemctl restart plasticscm-auth
4. Performance Bottlenecks
Understanding the Issue
Plastic SCM becomes slow, affecting commit times, branch switching, and overall responsiveness.
Root Causes
- Large repositories with excessive file history.
- Database fragmentation slowing down queries.
- Insufficient hardware resources.
Fix
Optimize database performance:
cm repack
Enable repository compression:
cm setrepositorycompression repo-name --enable
Monitor system resource usage:
htop
5. Workspace Corruption
Understanding the Issue
Workspaces become corrupted, leading to missing or untracked files.
Root Causes
- Unexpected system crashes or improper shutdown.
- File modifications outside Plastic SCM control.
- Conflicting file versions leading to inconsistencies.
Fix
Reset the workspace:
cm reset workspace-name
Revert to the last known good state:
cm undo
Check for modified files:
cm status
Conclusion
Plastic SCM is a powerful version control system, but troubleshooting repository synchronization failures, merge conflicts, authentication problems, performance bottlenecks, and workspace corruption is essential for maintaining smooth development workflows. By ensuring proper configurations, optimizing repository performance, and handling conflicts efficiently, teams can maximize the benefits of Plastic SCM.
