Replace zap with zerolog.
zerolog has a cleaner interface and can be easily configured with custom
error chain printing using a new error handling library that will be
implemented in another PR.
* Create an APIError that should only be used for api returned errors.
It'll wrap an error and can have different Kinds and optional code and
message.
* The http handlers will use the first APIError available in the
error chain and generate a json response body containing the code and
the user message. The wrapped error is internal and is not sent in the
response.
If no api error is available in the chain a generic internal
server error will be returned.
* Add a RemoteError type that will be created from remote services calls
(runservice, configstore). It's similar to the APIError but a
different type to not propagate to the caller response and it'll not
contain any wrapped error.
* Gateway: when we call a remote service, by default, we'll create a
APIError using the RemoteError Kind (omitting the code and the
message that usually must not be propagated).
This is done for all the remote service calls as a starting point, in
future, if this default behavior is not the right one for a specific
remote service call, a new api error with a different kind and/or
augmented with the calling service error codes and user messages could
be created.
* datamanager: Use a dedicated ErrNotExist (and converting objectstorage
ErrNotExist).
Replace https://github.com/satori/go.uuid with maintained version at
https://github.com/gofrs/uuid
Since the new version uuid.NewV4 returns an error when failing to read
from the random source reader we use uuid.Must to panic on error since
it's considered an unrecoverable error.
In future, if needed, we could handle the error instead of panicking.
Actual implementation doesn't fetch all repository. Gitea API has
pagination.
This patch works wwith gitea pagination for repository listing

since the git command output is redirected to the http response body, the golang
http server automatically adds a 200 status before sending the body. If the git
command fails we cannot return an http error anymore but must close the
connection to let the client know that the request failed.
Handle `.agola/config.star` files in starlark config format.
To provide a context like done for jsonnet we require that the starlark agola
config file contains a main function that will receive a config context as a
dict.
We also had to implement our own json conversion from a starlark dict since go
starlark removed its own function.
skip fetching of tasks with status skipped, not only tasks marked as skip.
This avoid many wrong an noisy logs of type "executor task with id taskid
doesn't exist. This shouldn't happen. Skipping fetching"
updateRunTaskStatus should also accept transitions from not started to a
finished state like "success", "failed", "stopped" since we could miss some
status updates from the executor for many reasons.
rename activeExecutorTasks to scheduledExecutorTasks and don't filter out
finished tasks.
In some logic we need all the scheduled tasks and not only the not finished
ones.
taskUpdater will be called serially and won't block. It'll execute a goroutine
for executing the task and for sending the task state to the scheduler.
executeTask will just start task execution, all the logic of choosing if
starting a task is moved inside taskUpdater
In this way we avoid concurrency issues when handling the same executorTask
in parallel
Since the executor only periodically updates its state we could end up
scheduling much more tasks than the executor ActiveTasksLimit. This will happen
in the case of many parallel tasks that can all start at the same time.
To avoid this also considere the executor tasks saved in etcd that represent
the real view of scheduled tasks.
Currently when a run is marked to stop we are going to stop currently running
tasks and then their childs will be marked as skipped.
But tasks not depending on a stopped task (root task or childs with a finished
parent) that are just waiting for an executor slot, will be scheduled when
there will be a free slot also if the run is marked to stop (and then the
scheduler will stop them after some seconds).
This patch will mark all not started tasks as skipped when the run is marked to
stop.
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.
