There's no test script. Full tests can be easily executed inside a local
running agola instance using an agola "direct run".
Single package tests can be executed using a manual go test invocation based on
the kind of package we want to test (since some of them require a running etcd,
a running docker, a running k8s cluster, a gitea binary etc...)
During tests provide a zaptest Logger so all services output will be redirected
to golang testing logger.
When multiple services of the same type are provided add a unique name field to
distinguish them.
Instead of doing the current hack of copying the agola toolbox inside the host
tmp dir (always done but only needed when running the executor inside a docker
container) that has different issues (like tmp file removal done by
tmpwatch/systemd-tmpfiles), use a solution similar to the k8s driver: for every
pod create a volume containing the agola-toolbox and remove it at pod removal.
We could also use a single "global" volume but we should handle cases like
volume removal (i.e. a docker volume prune command). So for now just create a
dedicated per pod volume.
Explicitly write and flush the headers in the various services LogHandlers.
Currently the 200 response and the other headers will be automatically written
by the golang http implementation only when we send something in the body. But if
there's nothing to send (no logs yet written) the client will never receive the
headers and cannot know if the request was successful.
* return errNotExist in readTaskLogs when the executor task doesn't exist: so
the client will receive a 404 instead of a 500 (since a generic error will be
mapped to a 500).
* Wrap the errNotExist returned by readTaskLogs with a new ErrNotExits reporting
"log doesn't exist"
etcd PR 11104 (https://github.com/etcd-io/etcd/pull/11104) implemented mutex
TryLock. Since it's only available in etcd master just copy relevant code and
add a TODO to remove it when updating the etcd client to a version implementing
TryLock.
Use TryLock everywhere where it'll be useful.
Rename errCh to doneCh (error is not needed) and always send to it when one of
the HandleEvents functions exits (not only on error).
This will ensure that all the goroutines will be stopped also if one of them
returns without an error.
