Ninja can find most of the dependent targets to pass to bazel in order to not need to build everything. Below are example findings from some prototyping.
# build base files for test ninja -f fast.ninja +bson_test # add code change to src/mongo/bson/bson_field.h time ninja -f fast.ninja +bson_test > real 0m59.211s # add code change to src/mongo/bson/bson_field_test.cpp time ninja -f fast.ninja +bson_test > real 0m34.088s # same as above but for opt build profile # add code change to src/mongo/bson/bson_field.h time ninja -f opt.ninja +bson_test > real 1m19.138s
Compared the same test to current master:
# build base files for test
ninja -f fast.ninja +bson_test
# add code change to src/mongo/bson/bson_field.h
time ninja -f fast.ninja +bson_test
> real 5m50.481s
