# zombietest
|
||
|
|
|
||
|
|
This directory contains an integration test to prove runsvinit is actually
|
||
|
|
reaping zombies. `make` builds and executes the test as follows:
|
||
|
|
|
||
|
|
1. We produce a linux/amd64 runsvinit binary by setting GOOS/GOARCH and
|
||
|
|
invoking the Go compiler. Requires Go 1.5, or Go 1.4 built with the
|
||
|
|
appropriate cross-compile options.
|
||
|
|
|
||
|
|
2. The build/zombie.c program spawns five zombies and exits. We compile it for
|
||
|
|
linux/amd64 via a zombietest-build container. We do this so `make` works
|
||
|
|
from a Mac. This requires a working Docker installation.
|
||
|
|
|
||
|
|
3. Once we have linux/amd64 runsvinit and zombie binaries, we produce a
|
||
|
|
zombietest container via the Dockerfile. That container contains a single
|
||
|
|
runit service, /etc/service/zombie, which supervises the zombie binary. We
|
||
|
|
provide no default ENTRYPOINT, so we can supply it at runtime.
|
||
|
|
|
||
|
|
4. Once the zombietest container is built, we invoke the test.bash script.
|
||
|
|
That launches a version of the container with runsvinit set to NOT reap
|
||
|
|
zombies, and after 1 second, verifies that zombies exist. Then, it launches
|
||
|
|
a version of the container with runsvinit set to reap zombies, and after 1
|
||
|
|
second, verifies that no zombies exist.
