Tips and Tricks
Run unit tests
The unit tests in pkg/sync must be run as root because they create files with various permissions/ownership.
It's easiest to run them using cd pkg/content && go test -c && sudo ./content.test -test.v.
Once you have build the test executable using go test -c, you can also run specific test or even testcases.
To run a specific test use sudo ./content.test -test.run TestName, to run a specific testcase use sudo ./content.test -test.run TestName -execute testcaseName.
Beware: when running all testcases (i.e. without -execute) the test itself will spawn a child process to recover from the permission drop across test cases.
This also means that not all -test. flags will be passed on to the children. At the moment it's only -test.v.
Tracing / Jaeger
ws-daemon has OpenTracing instrumentation which means you can get traces out of ws-daemon.
At the moment we just print the traces as log messages. If you want to run ws-daemon with a remote
Jaeger installation, you should set the following environment variables:
# set the Jaeger endpoint (e.g. an all-in-binary)
JAEGER_ENDPOINT=http://localhost:14268/api/traces
# set the sampler to const, to get all traces
JAEGER_SAMPLER_TYPE=const
# enable the constant sampler
JAEGER_SAMPLER_PARAM=1
