|
# USAGE
|
|
#
|
|
# 1. Follow instructions in https://source.android.com/setup/build/downloading to download
|
|
# the AOSP source and in https://source.android.com/setup/build/building to get proprietary
|
|
# binaries. You will need lots of space (at least 100Gb). Let <android-root> be its root as
|
|
# an *absolute path*.
|
|
#
|
|
# 2. Replace <android-root>/prebuilts/jdk/jdk9/<your OS>/bin/javac with the following script.
|
|
#
|
|
# #!/bin/bash
|
|
# infer -q --capture --continue --starvation-only --no-starvation \
|
|
# --project-root <android-root> --results-dir <android-root>/infer-out -- \
|
|
# /usr/local/bin/javac "$@"
|
|
#
|
|
# Here, my local installation of java is in /usr/local/, change accordingly. I used a
|
|
# Java *8* installation without problems, YMMV.
|
|
#
|
|
# 3. From <android-root> do
|
|
#
|
|
# $ . build/envsetup.sh
|
|
# $ export TEMPORARY_DISABLE_PATH_RESTRICTIONS=true
|
|
# $ cd libcore/ojluni
|
|
# $ mm -j1 javac-check
|
|
#
|
|
# ... and wait. It took me ~22h.
|
|
#
|
|
# 4. From <android-root> run
|
|
#
|
|
# $ infer analyze --starvation-only --dev-android-strict-mode
|
|
#
|
|
# 5. From <android-root> run this script, capturing stdout.
|
|
#
|
|
# $ <infer-root>/scripts/make-strict-mode.sh > \
|
|
# <infer-root>/infer/src/concurrency/StrictModeModels.ml
|
|
#
|
|
# 6. You may need to adapt the optional ~actuals_pred argument for methods in the above ML file.
|
|
# The aim is to avoid false positives when there is an overloaded method with different
|
|
# signatures and it so happens that one of the versions makes a violation when another does not.
|
|
# Recompile Infer.
