Server Development Platform
Description
If my build.ninja file is modified at all, then ninja must perform a full rebuild of all 3k+ objects for the mongod binary. This occurs most during git branch checkouts, which often modifies Scons dependencies. This makes branch checkouts, a commonly recommended server workflow, impractical.
The old ninja module was able to determine which files actually required rebuilding. We should consider making a similar optimization for the new Ninja generator.
