Pete Bacon Darwin c65ac7fbad perf(ivy): ngcc - exit early if the targeted package has been compiled (#29740) ... Previously we always walked the whole folder tree looking for entry-points before we tested whether a target package had been processed already. This could take >10secs! This commit does a quick check of the target package before doing the full walk which brings down the execution time for ngcc in this case dramatically. ``` $ time ./node_modules/.bin/ivy-ngcc -t @angular/common/http/testing Compiling @angular/core : fesm2015 as esm2015 Compiling @angular/core : fesm5 as esm5 Compiling @angular/core : esm2015 as esm2015 Compiling @angular/core : esm5 as esm5 Compiling @angular/common/http : fesm2015 as esm2015 Compiling @angular/common/http : fesm5 as esm5 Compiling @angular/common/http : esm2015 as esm2015 Compiling @angular/common/http : esm5 as esm5 Compiling @angular/common/http/testing : fesm2015 as esm2015 Compiling @angular/common/http/testing : fesm5 as esm5 Compiling @angular/common/http/testing : esm2015 as esm2015 Compiling @angular/common/http/testing : esm5 as esm5 real 0m19.766s user 0m28.533s sys 0m2.262s ``` ``` $ time ./node_modules/.bin/ivy-ngcc -t @angular/common/http/testing The target entry-point has already been processed real 0m0.666s user 0m0.605s sys 0m0.113s ``` PR Close #29740		2019-04-08 09:48:20 -07:00
