Merge remote-tracking branch 'aosp/upstream' * aosp/upstream: Switch from vfork to posix_spawn Fix parallel tests Update Dockerfile to pass tests Change-Id: I66fc6e2058ef14e048a64341be90470c6c5d00c6
kati is an experimental GNU make clone. The main goal of this tool is to speed-up incremental build of Android.
Currently, kati does not offer a faster build by itself. It instead converts your Makefile to a ninja file.
Building:
$ make ckati
The above command produces a ckati binary in the project root.
Testing (best ran in a Ubuntu 20.04 environment):
$ make test $ go test --ckati $ go test --ckati --ninja $ go test --ckati --ninja --all
The above commands run all cKati and Ninja tests in the testcases/ directory.
Alternatively, you can also run the tests in a Docker container in a prepared test enviroment:
$ docker build -t kati-test . && docker run kati-test
If you are working on a machine that does not provide make in the same version as kati is currently compatible with, you might want to download a prebuilt version instead. For example to use the prebuilt version of Ubuntu 20.04 LTS:
$ mkdir tmp/ && cd tmp/ $ wget http://mirrors.kernel.org/ubuntu/pool/main/m/make-dfsg/make_4.2.1-1.2_amd64.deb $ ar xv make_4.2.1-1.2_amd64.deb $ tar xf data.tar.xz $ cd .. $ PATH=$(pwd)/tmp/usr/bin/:$PATH make test
For Android-N+, ckati and ninja is used automatically. There is a prebuilt checked in under prebuilts/build-tools that is used.
All Android's build commands (m, mmm, mmma, etc.) should just work.
