Fail find parsing for \* Android hit a few cases where we were searching for *.pyc or verifiedboot*, and escaping the * as \*. In most cases the entire argument was just quoted instead. Kati understands and handles the quotes just fine, but it didn't realize that \* was special, so it was searching for files that started with a literal '\'. We have no good way of freeing allocated memory in the find parser, so just support stripping a leading \ (\*.pyc works, along with '\('), and fall back to the system find if another \ is found in a token.
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.
Now AOSP has kati and ninja, so all you have to do is
% export USE_NINJA=true
All Android's build commands (m, mmm, mmma, etc.) should just work.
Set up kati:
% cd ~/src % git clone https://github.com/google/kati % cd kati % make
Build Android:
% cd <android-directory> % source build/envsetup.sh % lunch <your-choice> % ~/src/kati/m2n --kati_stats # Use --goma if you are a Googler. % ./ninja.sh
You need ninja in your $PATH.
% ./ninja.sh -t clean
Note ./ninja.sh passes all parameters to ninja.
For example, the following is equivalent to "make cts":
% ./ninja.sh cts
Or, if you know the path you want, you can do:
% ./ninja.sh out/host/linux-x86/bin/adb
