PROBLEM
|
|
|
|
The testing methodology of Gluster is extremely slow. It takes a very long time (6+ hrs) to run the basic tests on a single machine. It takes about 20+ hours to run code analysis version of tests like valgrind, asan, tsan etc.
|
|
|
|
SOLUTION
|
|
|
|
The fundamental problem is that the tests cannot be parallelized on a single machine. The natural solution is to run these tests on a cluster of machines. In a nutshell, apply map-reduce to run unit tests.

|
WORK @ Facebook
|
|
|
|
At Facebook we have applied the map-reduce approach to testing and have observed 10X improvements.
|
|
|
|
The solution supports the following
|
|
|
|
Distribute tests across machines, collect results/logs
|
|
Share worker pool across different testers
|
|
Try failure 3 times on 3 different machines before calling it a failure
|
|
Support running asan, valgrind, asan-noleaks
|
|
Self management of worker pools. The clients will manage the worker pool including version update, no manual maintenance required
|
|
WORK
|
|
|
|
Port the code from gluster-fb-3.8 to gluster master
|
|
|
|
HOW TO RUN
|
|
|
|
./extras/distributed-testing/distributed-test.sh --hosts '<h1> <h2> <h3>'
|
|
|
|
All hosts should have no password for ssh via root. This can be achieved with keys setup on the client and the server machines.
