Simone Gotti b81ad4cd8c runservice: fix/improve executor delete logic
* Don't fail tasks inside the delete executor action, just delete the executor
from etcd

* The scheduler, when detecting a task without a related executor will mark the
task as failed and correctly set end time of the task and its steps.

Simone Gotti f812597410 runservice: maintenance/export/import
Implement runservice maintenance mode and export/import.

When runservice is set in maintenance mode it'll start only the maintenance and
export/import handlers.

Setting maintenance mode will set a key in etcd so all the runservice instances
will detect it and enter in maintenance mode. This is done asyncronously so it
could take some time (future improvements will add some api to show all the
runservice states)

Export is always available and will export the datamanager contents. Currently
only datamanager contents are exported (no logs and workspace archives).

Import is available only during maintenance, given a datamanager export will
import it and reset etcd to this import state.

Simone Gotti 6f3798e8fe *: use sleep timer in loops
So we'll react instantly to a context cancel instead of waiting on time.Sleep
returning.

Simone Gotti b8c2b4020a db: use context functions
Use the go sql context functions (ExecContext, QueryContext etc...)

The context is saved inside Tx so the library users should only pass it one time
to the db.Do function.

readdb: fix deadlock in Run method

Simone Gotti 85876310af readdb: fix deadlock in Run method
In runservice readdb Run method we could end with a deadlock if two of the
goroutines that call HandleEvents.* try to write to the errCh at the same
time before the errCh is read. If this happens one of the two will be blocked on
writing to the channel but the read won't happen since it'll blocked by
wg.Wait().

Fix this doing:
* use a buffered channel large as the number of executed goroutines.
* create a new errCh at every loop (so we'll ignore later errors after the first
one)

Note: we could also use a non blocking send to avoid this situation but we
should also start the wg.Wait before the goroutines or earlier errors could be
lost causing another kind of hang.

Simone Gotti 11a2ff48d6 runservice: delete executor task early
currently we are deleting the executor tasks only when all the run tasks
log/archives were fetched. But it'll better to remove a single executor task
when the task fetching is finished.

This could also fix possible issues on k8s since we are scheduling tasks but the
k8s scheduler may not schedule them if there aren't enough resources causing a
scheduling deadlock since we won't remove finished pods because their related
tasks are not removed and k8s cannot start new pods since it has no resources.

Simone Gotti 5db23410d0 runservice: set base path for datamanager
Don't put datamanager base dirs inside the root of the ost but use a base path.

Let's do it now before releasing since this is a breaking change that requires
moving the ost data to the new path

Currently we aren't setting a basepath and it wasn't always correctly handled.
Fix missing basepath handling and improve tests to also use a non empty
basepath.

Simone Gotti 87a472aaaf runservice: add CacheGroup field to runconfig
The cache group fields defines under which cache group the run cache data will
belong. This is needed/useful for some next changes:

* Make cache correctly work for user direct runs. Since the user direct runs all
belong to the same run group (the user id) all the use direct runs will share the
same caches. To distinguish between the different caches we need to use something
in addition to the user id (the local repo uuid generated by the direct run
start command)
* Share the cache between multiple projects

Simone Gotti 6e8d467c80 util: add ErrInternal
ErrInternal is an internal error that should be provided to the user (http api
will return a 500 with the error message)

It'll be used for any kind of error that are not auth or bad requests (like
errors to communicate to another service)

Simone Gotti 863277af2d runservice types: refactor unmarshal
* Don't use a complex UnmarshalJSON for RunConfigTask and ExecutorTask but
introduce a Steps type as a slice of Step (where Step is an empty interface)
and declare an UnmarshalJSON method on the Step type.

Simone Gotti 4d7605a86b gateway: improve ErrFromRemote handling
Don't create an ErrFromRemote wrapping the returned error but
wrap the ErrFromRemote

Also use xerrors Is/As to get the underlying error to return to api clients
while maintaining context for logging

Simone Gotti 9b2ce717c7 *: migrate to "golang.org/x/xerrors"
Just a raw replace of "github.com/pkg/errors".

Next steps will improve errors (like remote errors, api errors, not exist errors
etc...) to leverage its functionalities

Simone Gotti b3867fb7ca objectstorage: add posix standard storage
rename the previous posix storage to posixflat and make it currently not user
selectable (since I'm not sure it's really worth using it).

The new posix storage uses the filesystem without any escaping so it's not a
real flat namespace.

This isn't a real issue since also minio is not a flat namespace and we are so
forced to use it like a hierarchycal filesystem.

Simone Gotti bec9476d6c runservice: store related runid with logs and archives
Logs and archives can be shared by multiple runs. So removing a run doesn't
imply that we could also remote the logs and archives since they could be
"referenced" by another run.

Store also the runids as specific objects along with the logs and archives so,
we'll remove them only when no runids objects exist.

Simone Gotti 1e34dca95d runservice: split and simplify scheduler and executor naming
Also if they are logically part of the runservice the names runserviceExecutor
and runserviceScheduler are long and quite confusing for an external user

Simplify them separating both the code parts and updating the names:

runserviceScheduler -> runservice
runserviceExecutor -> executor

Simone Gotti e4e7de4ad2 runservice/gateway: return run on run action 2019-05-07 23:23:58 +02:00
Simone Gotti afae185e11 *: rework run approval and annotations
* runservice: use generic task annotations instead of approval annotations
* runservice: add method to set task annotations

* gateway: when an user call the run task approval action, it will set in the
task annotations the approval users ids. The task won't be approved.

* scheduler: when the number of approvers meets the required minimum number
(currently 1) call the runservice to approve the task

In this way we could easily implement some approval features like requiring a
minimum number of approvers (saved in the task annotations) before marking the
run as approved in the runservice.
