+# Simulating GitHub Actions
+
+Sometimes a test failure that occurs in the GitHub Actions CI cannot be
reproduced locally. You can try to run the tests in a more similar environment
using https://github.com/nektos/act
+
+1. Install act according to its instructions
+2. Edit `.github/workflows/ci.yml` to remove extra "matrix" elements and
adjust the maven command line to set the tests you are interested in: ```run:
mvn install -Dsurefire.useFile=false -DtrimStackTrace=false
-Dtest=org.apache.drill.exec.server.rest.TestQueryWrapper
-DfailIfNoTests=false```
+3. Run `act -P ubuntu-latest=nektos/act-environments-ubuntu:18.04 --job build`
to run the build
+
# IntelliJ
-TBA
+IntelliJ IDEA has decent support for maven built in, IntelliJ IDEA users can
use these steps to get up and running:
+
+First, import maven pom.xml as projects.
+
+Change settings in File > Settings > Build, Execution, Deployment > Build
Tools > Maven:
+
+ 1. Enable "Work Offline" to avoid checking for dependency updates on every
run
+ 2. Increase the "Thread Count" to speed up builds - a reasonable default is
the number of CPU cores you have
+ 3. Go to the "Runner" subsection
+ 4. Enable "Delegate IDE build/run actions to Maven". The IDE didn't seem to
do things in a manner compatible with running the application
+ 5. Enable "skip tests" you will probably want to run tests manually rather
than every time you try to run something
+ 6. To skip some uninteresting build steps, you can also set the following
properties to `true`: `checkstyle.skip`, `findbugs.skip`, `license.skip`,
`maven.javadoc.skip`, `rat.skip`, `skipIfEmpty`
+
+At this point you should be able to use the built-in IDE features to run tests
+
+Running/debugging Drillbit is also possible:
+ 1. Create a new run configuration on the class
`org.apache.drill.exec.server.Drillbit`
+ 2. you have to create a run configuration and set the VM parameters:
+
+ -Xms4G
+ -Xmx4G
+ -XX:MaxDirectMemorySize=8G
+ -XX:ReservedCodeCacheSize=1G
+ -Ddrill.exec.enable-epoll=false
+ -XX:MaxPermSize=512M
+ -XX:+CMSClassUnloadingEnabled
+ -XX:+UseG1GC
+ -Dlog.path=/opt/drill/log/drillbit.log
+ -Dlog.query.path=/opt/drill/log/drillbit_queries.json
+ -Xbootclasspath/a:/opt/drill/conf
Review comment:
This is only needed to simulate a "real" drillbit. In that case, I've found
it easier to just add an `DRILLBIT_JAVA_OPTS` variable, in the environment or
in `drill-env.sh` to enable remote debugging. Then, just connect to the running
Drillbit from your IDE and you are assured to be using all the right config.
What is describe here works, just is a bit fiddly.
You can also see that config with `drillbit.sh debug`.
