Currently we are using different `When` types for every service and convert
between them. This is a good approach if we want to keep isolated all the
services (like if we were using different repos for every service instead of the
current monorepo).
But currently, since When is identical between all the services, simplify this by
using a common When type.
Currently `advanceRunTasks` isn't deterministic and doesn't calculate the final
state in one call. So could happen that `getTasksToRun` will select a task to be
executed since its parent are finished (marked as skipped in advanceRunTasks)
but the task isn't marked to be skipped (because advanceRunTasks has calculated
this task before its parents).
Currently fix this doing the same task selection logic done in `advanceRunTasks`
and add a TODO to make `advanceRunTasks` be deterministic by processing tasks by
their level (from level 0).
In c1ff28ef9f we exported various types. Unfortunately the types used by cmd
variable create/update are the wrong types and marshalling fails. Fix it using
the right type. In future this internal types should be exported.
Since the current logic is to use the first available private ip address as the
advertized address we have to listen on wildcard since a different host provided
in web.ListenAddress will make the executor unreachable.
In future improve this to let the user to manually define the bind and the
advertized address (perhaps using go-sockaddr templates like done by consul) to
also support nat between the schedulers and the executors.
Allow setting the destination branch/tag/ref so users can test the run
conditions based on the branch/tag/ref.
To simulate a pull request an user can define a ref that matches one of these
regular expressions: `refs/pull/(\d+)/head`, `refs/merge-requests/(\d+)/head`
Older version of docker doesn't support the exec api Env and WorkingDir options.
Support these versions by doing the same we already do with the k8s driver: use
the `toolbox exec` command that will set the provided Env, change the cwd to the
WorkingDir and the exec the wanted command.
Export clients and related packages.
The main rule is to not import internal packages from exported packages.
The gateway client and related types are totally decoupled from the gateway
service (not shared types between the client and the server).
Instead the configstore and the runservice client currently share many types
that are now exported (decoupling them will require that a lot of types must be
duplicated and the need of functions to convert between them, this will be done
in future when the APIs will be declared as stable).
Since they're not types common to all the services but belongs to the
configstore.
Next step will be to make them local to the configstore and not directly used by
other services since these types are also stored.
* 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.
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.
There was a typo so we weren't setting the task endTime when the setup step
failed.
Also unify all logic to just use `et` (instead of a mix of `et` or `rt.et`)
