Simone Gotti 9cfb21d365 gateway: run api return more step data
For every step return the step type.

For a run step also return the shell and exit status.

Simone Gotti 39829f1ec4 runservice: save step exitstatus in run.
For every step save also the command exit status.

Simone Gotti 12b02143b2 runservice: don't save executor task data in etcd
Reorganize ExecutorTask to better distinguish between the task Spec and
the Status.

Split the task Spec in a sub part called ExecutorTaskSpecData that contains
tasks data that don't have to be saved in etcd because it contains data that can
be very big and can be generated starting from the run and the runconfig.

Simone Gotti 6ee76274d7 executor: set the container exec user in every step 2019-09-12 10:55:07 +02:00
Simone Gotti 51e9a32db7 runconfig: set task default shell
Currently, if no shell is defined in the task and in the step, the executor will
use an hardcoded default shell.

This will cause changed run behavior if we add an option to globally set the
agola default shell.

To avoid this set the task shell to the default shell inside the runconfig if
it's empty so future executions will always use this value.

Simone Gotti 6d7410cfce runservice: remove run step user
Defining an option to override the user for a run step is too much fine grained
and, for consistency, will require to do the same also for the other steps
(clone, *workspace etc...).

Remove it since it's probably enough to define it at the task level.

Merge pull request #103 from sgotti/gitserver_dont_write_on_error

Simone Gotti 0e61aa4e39 gitserver: don't return http response/error when calling external git process
On a git process error don't write the error message to the response body since
it'll break the git protocol and don't try to write the status header (since it's not
possible as it was automatically written by the go http server before writing
the body).

Simone Gotti 70eeddb719 types: use a global When type
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.

Simone Gotti bfc42ef60e runservice: fix get tasks to run
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).

Simone Gotti 53dad95cd0 cmd: fix variable create/update
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.

Simone Gotti e31b0b47ef executor: listen on wildcard address
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.

Simone Gotti 4ec0b33eb4 userdirectrun: allow setting destination branch/tag/ref
Allow setting the destination branch/tag/ref so users can test the run
conditions based on the branch/tag/ref.

regular expressions: `refs/pull/(\d+)/head`, `refs/merge-requests/(\d+)/head`

Simone Gotti b3672bf927 docker driver: use toolbox exec
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.

Simone Gotti c1ff28ef9f *: export clients and related types
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).

Simone Gotti fd26e617b3 configstore: move configstore types inside configstore package
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.

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 0ecfc24def executor: fix typo in setting task endTime when setup failed
There was a typo so we weren't setting the task endTime when the setup step

Simone Gotti 3404cb94b9 datamanager: implement import/export
* export: exports the newest data checkpoint. It forces a checkpoint before
exporting (currently no wals are exported)

* import: cleans up etcd, creates a new datasnaphot from the provided import stream
and then initializes etcd. Currently no old data is removed from the object
storage but it's just ignored.

Simone Gotti 3297244d5d db: retry on sqlite locked error
Since we are using the shared cache with the lock notify we won't receive
SQLITE_BUSY errors but we could receive SQLITE_LOCKED errors due to deadlocks or
locked tables on concurrent read and write transactions.

This patch catches this kind of errors and retries the tx until maxTxRetries.

readdb: fix deadlock in Run method
2019-07-23 15:47:05 +02:00
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.
