Enables lineage reconstruction, which allows automatic recovery of task outputs, by default.
Also adds an info message to the driver whenever objects need to be reconstructed (not including recursive reconstruction).
#22714 added `serve run` to the Serve CLI. This change allows the user to specify `init_args` and `init_kwargs` in `serve run` if they are deploying via import path.
Updates grpc to 1.44.0 to remove local patch needed for grpc to build.
EDIT: there have been changes to how python is found (mostly removing python2 support) and as such the local python-patch we have for grpc needs to be modified.
This time contributing it to upstream (grpc/grpc#28895) so that it'll get added in a newer version!
For anyone that comes across this:
Here is the error itself for why we need the grpc-python.patch file: https://buildkite.com/ray-project/ray-builders-pr/builds/24659#d293616f-225d-41f9-8de2-03780f12b13f/2386-2416
Currently, classes and functions can be deployed by setting `Deployment`'s`func_or_class` to their import path. However, if these classes or functions are already decorated with `@serve.deployment`, the import path deployment will error.
This change instead ignores the settings in a class or function's `@serve.deployment` decorator when deploying via import path. It takes the code definition and deploys it without erroring. It also logs a warning about the ignored settings.
The REST API's schema default denies HTTP access to deployments when `route_prefix` is omitted. This doesn't match `@serve.deployment`'s behavior, which make `route_prefix` the deployment's name when omitted.
This change matches the schema's behavior to the decorator. When `route_prefix` is omitted from the config, the deployment's `route_prefix` defaults to its name. When the `route_prefix` is specified as `null`, the deployment won't have HTTP access.
This change also fixes a bug in Serve where when a deployment is updated from a non-`None` `route_prefix` to a `None` `route_prefix`, its `route_prefix` does not change. This bug meant that a deployment available over HTTP would continue to be available at the same route even when deployed again with `route_prefix=None`.
- Enhanced ray dag InputNode to take arbitrary user input via `.execute()`.
- If only one value is provided, like `dag.execute(1)`, return raw value;
- Otherwise wrap user input into an `DAGInputData` object that can be accessed via index or key.
- User can also pass list / dict object and just access them via index [0] or key ["key"]
- Introduced `InputAttrNode` that helps to connect partial attribute of user input to the DAG.
- Added context manager syntax for `InputNode`.
- Add InputNode enforcements with tests, such as DAG level singleton, exception with messages, etc.
- Enforce only simple int or str key
- Take care of JSON serialization for InputNode that carried original context manager info, ensure it's preserved.
- DAGNode UUID is also preserved in JSON serde.
## Next steps
On ray dag level we're proceeding with
```
with InputNode() as input: # Probably better to rename it to DAGInput()
a = Model.bind(input[0])
b = Model.bind(input.x)
dag = combine.bind(a, b)
```
But also enforces
1) InputNode is always used in context manager as opposed to directly created
2) There should be one and only one InputNode instance for each dag.
3) No args passed by user to InputNode at ray dag level.
Then in serve we subclass a ServeInputNode() to enhance it like the following to support HTTP input validation and conversion:
```
with ServeInputNode(schema=MySchemaCls) as input:
a = Model.bind(input[0])
b = Model.bind(input.x)
dag = combine.bind(a, b)
```

There are problems with running C++ tests in MacOS 10.15 Catalina, when upgrading to the newest grpc due to dynamic linking: #22384 (comment). The problem does not exist for Python tests in Catalina, or in C++ tests of other systems.
Upgrading MacOS CI from Catalina is also blocked in the short term: ray-project/buildkite-ci-stack#24 (comment)
So working around the issue by using static linking for C++ tests on Mac.
This PR allows `DatasetPipeline.iter_batches()` to batch data across windows in the pipeline. This prevents partial batches from popping up in the middle of consuming a dataset pipeline due to window boundaries, and now allows us to provide the following guarantee to the user: `pipe.iter_batches()` will yield `len(pipe) // batch_size` full batches, with a partial batch occurring only (1) as the final batch and (2) only if `len(pipe) % batch_size > 0`, and if it exists, will have size `len(pipe) % batch_size`.
The crux of this PR takes the block batching implementation from `Dataset.iter_batches()`, refactors it to operate on an iterator of blocks instead of a `Dataset` and pulls it out into a shared `batch_blocks()` utility, and have `DatasetPipeline.iter_batches()` use it to batch over windows by providing an iterator over all blocks in all windows.
When there is no scheduling task of scheduling class in local raylet, the backlog resource will not be reported. It usually will happen when core worker try to schedule the task on other node and report backlog to local node.
This will lead to the wrong demands.
As we are turning redisless ray by default, dashboard doesn't need to talk with redis anymore. Instead it should talk with gcs and gcs can talk with redis.
horovod_user_test_master is failing with recent horovod release[[link](https://buildkite.com/ray-project/periodic-ci/builds/2960#61dabda8-eea0-4b7b-93bf-9e341926d3fd)].
Error message is saying:
```
AttributeError: Can't get attribute '_ExecutorDriver' on <module 'horovod.ray.runner' from '/home/ray/anaconda3/lib/python3.7/site-packages/horovod/ray/runner.py'>
```
The horovod test is set up in such a way that it has the "driver" (a.k.a. client) part (which is the code that runs in a buildkite agent) and the "cluster" (a.k.a. server) part (which runs in Anyscale cluster). Driver's dependency is specified by `release/ml_user_tests/horovod/driver_setup_master.sh` while cluster's dependency is specified by `release/horovod_tests/app_config_master.yaml`.
The two communicate via Anyscale client.
The above error message is complaining that while client's horovod version has _ExecutorDriver in runner.py, the server's horovod doesn't. This is due to the version mismatch of the above two files. This PR brings the two horovod dependency to both point to horovod master.
This change adds `run`, `delete`, and `status` commands to the CLI introduced in #22648.
* `serve run`: Blocking command that allows users to deploy a YAML configuration or a class/function via import path. When terminated, the deployment(s) is torn down. Prints status info while running. Supports interactive development.
* `serve delete`: Shuts down a Serve application and deletes all its running deployments.
* `serve status`: Displays the status of a Serve application's deployments.
Added JSON serde for all DAGNode types needed with tests on ray core dag as well as serve dag. See code inline comments for behavior and assumption for each.
Previously, for the stability of pip installation, we set env to empty, but when pip installs some gzip package, maybe need env_vars. like this issue: https://github.com/ray-project/ray/issues/22610
This PR adds concurrency groups to Buildkite release test runs with new release test package. Five concurrency groups are defined (large-gpu, small-gpu, large, medium, small). If not specified manually, concurrency groups are inferred from used cluster resources.
Example pipeline: https://buildkite.com/ray-project/release-tests-branch/builds/55#09109eac-d22e-43bc-889e-078cfb037373 (click on Artifacts --> pipeline.json)
This updates the GPU image to run on the same Ubuntu version as the regular (non-GPU) image. This implicitly updates cmake etc for compatibility with newer versions of downstream libraries, e.g. Horovod.
Example for running notebooks on our docs directly in the browser by connecting to a binder instance launched on demand.
If this seems useful we can extend this to other examples gradually.

This PR move the poller and broadcaster from gcs server to ray syncer.
TODO in next PR: deprecate the code path of placement group resource reporting and move the broadcaster out of gcs cluster resource manager.
Adds an API to the REST server, the SDK, and the CLI for listing all jobs that have been submitted, along with their information.

DatasetPipeline execution is coordinated by a pool of actors and optionally the driver process. To recover from failures with lineage reconstruction, we need to keep these actors alive as long as the driver is alive. Currently, they are spread randomly throughout the cluster, so they can be killed during a node failure.
This PR pins the actors to the same node as the driver so that they will survive any other node failures. It's also okay if the driver node dies, since the driver itself will also die.
Don't re-use task workers for actors, since those workers may own objects that will be lost on actor exit.
This adds a slight performance penalty for actor startup.
