steps-for-ci | Recommended flow for CI |
The recommended flow for CI integration is to determine the modified files, and run the analysis in reactive mode starting from those files. If you would like to run more than one analyzer, it is more efficient to separate the capture phase, so that the result can be used by all the analyzers.
Differential Workflow
Here's how to run infer on two versions of a project and compare the results in general.
Assume the project uses git, feature
is the feature branch (the code change
you want to analyze), master
is the master branch, and make
builds the
project.
# go to feature branch if not there already
git checkout feature
# get list of changed files
git diff --name-only origin/feature..origin/master > index.txt
## first run: feature branch
# run infer on the feature branch
infer capture -- make -j 4 # assuming a machine with 4 cores
infer analyze --changed-files-index index.txt
# store the infer report
cp infer-out/report.json report-feature.json
## second run: master branch
git checkout master
# run capture in reactive mode so that previously-captured source files are kept if they are up-to-date
infer capture --reactive -- make -j 4
infer analyze --reactive --changed-files-index index.txt
# compare reports
infer reportdiff --report-current report-feature.json --report-previous infer-out/report.json
At the end of this process, "infer-out/differential/" contains three files, which follow the same format as normal infer JSON reports:
- introduced.json contains the issues found in the feature branch but not in master;
- fixed.json contains the issues found in master but not in the feature branch;
- preexisting.json contains the issues found in both branches.
Example: Android Gradle
The following CI script runs the infer
and eradicate
analyzers. Assume again
that feature
is the feature branch, and master
is the master branch.
git diff --name-only origin/feature..origin/master > index.txt
infer capture -- ./gradlew --offline assembleDebug
infer analyze --fail-on-issue --eradicate --changed-files-index ./index.txt
Notice that
- We use git to find the changed files
git diff --name-only
- We run capture only once, and the output is kept for the subsequent analyses
- We run the eradicate analysis alongside the default analyses:
--eradicate
- We analyze only the changed files
--changed-files-index ./index.txt
