Keeping Test and Production Servers in Sync Safely
A test server is useful only if deployment back to production is deliberate, repeatable, and does not overwrite live data blindly every night.
The donor proposed a common maintenance workflow: make changes on a test server, then synchronize them to production on a schedule. The core challenge is not whether syncing is possible — it is how to do it without damaging live content.
What needs separation
- code and templates
- database content
- uploaded media
- environment-specific config
Why nightly full syncs are risky
If editors continue working on production, a blind overnight sync from test can overwrite real data. That is why deployment should be release-oriented, not just “copy the server”.
Recommendation
Version the code, plan DB changes explicitly, and treat media and content sync separately. The goal is controlled deployment, not mirroring everything by habit.
Why Database Time Is Not Zero Even When Query Count Is Zero
A zero query count in parser stats does not always mean truly zero database-related overhead; some measured timings can still include framework or connection-layer work.
Fixing alias_visible Errors After Moving a Site to Another Server
An “unknown column alias_visible” error during migration usually means the database schema and the codebase are no longer from the same Evolution generation.
