📝 WalkthroughWalkthroughThe pull request updates cloud-provider and node-group implementations to use context-aware interfaces. GCE internal operations and logging now propagate contexts. Tests and wrappers pass contexts to updated APIs. Autoscaling loops now pass an iteration counter to each run. ChangesContext-aware provider and node-group APIs
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The change can cause canceled autoscaling operations and cloud-resource mutations to continue running, while some GCE operations may report failure before their configured wait period completes. The PR is not merge-ready until context propagation and GCE operation-wait handling are corrected or explicitly accepted by the owners.

Same question as for the PR in core CA - why not just propagate ctx here (and similarly for all the other providers)?

There was a problem hiding this comment.
IIUC DescribeScalingActivities already takes context as first param before this PR, and the unit test here uses mock.Anything to signify no assertions on the context param - any context should be fine.
Changing mock.Anything to context.TODO() changes this assertion to only accept the empty context created by context.TODO(). We probably shouldn't be changing the meaning of existing tests as part of this PR. Same applies to all the other unit tests where mock.Anything is replaced with something more restrictive.

Shouldn't the context in most unit tests be context.Background() instead of context.TODO()? IIUC context.TODO() is meant to signify that this is meant to be replaced with something else in the future. Is that true for the usage in unit tests, wouldn't we just always want an empty context there?

What's the logic behind which methods the context is propagated to? Why did we add the context param here, but not e.g. to FindForInstance()?

Propagate the received context to downstream work.
These methods accept ctx but create a new context before GPU detection, node lookup, refresh, or debug work. This prevents caller cancellation, deadlines, and contextual logging values from reaching those operations.

kubernetes autoscaler "GetNodeGPUFromCloudProvider" source
💡 Result:
The GetNodeGPUFromCloudProvider function is located in the Kubernetes Autoscaler repository within the cluster-autoscaler/utils/gpu/gpu.go file [1]. This function is a utility that identifies GPU resources on a node by interacting with a provided cloud provider interface [1]. It returns a *cloudprovider.GpuConfig struct containing the GPU label, the GPU type (from node labels), and the detected extended resource name if a GPU is present; otherwise, it returns nil [1]. Implementation details: - File path: cluster-autoscaler/utils/gpu/gpu.go in the kubernetes/autoscaler repository [1]. - Purpose: It abstracts the logic for checking if a node possesses GPU hardware, leveraging the cloud provider's GPU label definition [1]. - Integration: It is utilized by various cloud provider implementations in the Autoscaler (e.g., AWS, Azure) via their respective GetNodeGpuConfig methods to reconcile GPU node information [2][3].

Pass ctx to gpu.GetNodeGPUFromCloudProvider.
The helper forwards its context to provider.GPULabel(ctx). All six methods pass context.TODO() instead of the caller’s ctx, which can drop caller context values, cancellation, and deadlines.

Pass the caller context to the affected GCE query methods.
The affected paths invoke methods that create requests with independent context.Background() timeouts. These requests can continue after caller cancellation or deadline expiry. Add context parameters and pass the caller context through each path.

Preserve the configured operation wait budget.
ResizeMig, CreateInstances, and DeleteInstances pass the request-timeout context to WaitForOperation. The wait may therefore end when the mutation request’s deadline expires, before operationWaitTimeout. Use a request-specific context for each mutation request, then pass the original caller context to WaitForOperation.

google.golang.org/api/compute/v1 InstancesListCall Pages context.Context cancellation generated Go client
💡 Result:
In the Go client libraries for Google Cloud, context cancellation and timeout behavior depend on which generation of the library you are using [1][2][3]. There are two primary client libraries for Google Compute Engine in Go: 1. The older, legacy library (google.golang.org/api/compute/v1) [1]: This library uses a builder pattern for API calls. To cancel or set a timeout on an InstancesListCall, you use the.Context(ctx) method [4][5]. As documented in similar packages (e.g., SQL Admin) within the same repository, calling.Context(ctx) sets the context to be used during the.Do method; any pending HTTP request will be aborted if the provided context is canceled [4][6]. 2. The modern, recommended library (cloud.google.com/go/compute/apiv1) [2][3]: This library uses generated clients that are idiomatic to modern Google Cloud Go development [7]. For listing instances, you create a client and call its List method, passing a context.Context directly [8][9]: it:= client.List(ctx, req) for { resp, err:= it.Next //... } In this modern library, individual methods use the context passed to them [7]. To cancel the operation or apply a timeout, you should pass a context with a timeout or cancellation signal (created via context.WithTimeout or context.WithCancel) to the List method [10]. The underlying gRPC or REST transport will respect this context and abort the operation upon cancellation or deadline expiration [10][7]. Summary: - For legacy (google.golang.org/api/compute/v1): Use the.Context(ctx) method on the call object before executing.Do [4][5]. - For modern (cloud.google.com/go/compute/apiv1): Pass a managed context (with timeout or cancellation) directly to the method, such as List [9][10][7].

site:github.com/googleapis/google-api-go-client "func (c *InstancesListCall) Pages" "Context"
💡 Result:
The Pages method on generated Go client list calls (such as *InstancesListCall) is a helper function provided by the google-api-go-client library to simplify pagination [1]. It automates the process of iterating through multiple pages of results by handling the page token internally [1]. Signature: func (c *InstancesListCall) Pages(ctx context.Context, f func(*InstancesListResponse) error) error How it works: 1. It takes a context.Context and a callback function f [1]. 2. The callback function f is executed for each page of results, receiving the response object (e.g., *InstancesListResponse) as an argument [1]. 3. If the callback function returns an error, the iteration stops immediately and that error is returned by the Pages method [1]. 4. The method automatically manages the next page token retrieval and subsequent API calls until all pages have been fetched or the callback function halts the process [1]. Usage Example: err:= service.Instances.List(projectID, zone).Pages(ctx, func(page *compute.InstancesListResponse) error { for _, instance:= range page.Items { fmt.Println(instance.Name) } return nil // Return error to stop iteration }) Important Notes: - Availability: Not all list calls in older or specific APIs may have a Pages method [2]. If it is missing, you must manually implement a loop using the page token returned in the response object [2]. - Library Context: This Pages method is specific to the auto-generated Google APIs Client Library for Go (google.golang.org/api) [3][4]. If you are using the newer, idiomatic Cloud Client Libraries (github.com/googleapis/google-cloud-go), they use a different iterator pattern [3].

github google-api-go-client compute v1 compute-gen.go "func (c *InstancesListCall) Pages" "c.ctx_"
💡 Result:
The Pages method in the google-api-go-client (the auto-generated library) is designed to simplify pagination when working with Google API collection resources [1][2][3]. In the context of an InstancesListCall (or similar collection list calls in this library), the Pages method signature is: func (c *InstancesListCall) Pages(ctx context.Context, f func(*InstancesListResponse) error) error The behavior and purpose of this method are as follows: 1. Automatic Pagination: It abstracts the manual management of PageToken [2][4]. It automatically iterates through all available pages of results from the API by calling the underlying service repeatedly until all pages are retrieved or the function f returns an error [2][3]. 2. Context Usage: The ctx parameter provided to Pages is used for the API requests [2]. Importantly, the documentation notes that this context supersedes any context that might have been provided earlier via the Context() method on the same call object [2]. 3. Iteration Callback: The provided function f is invoked for each page of results (*InstancesListResponse) [2][3]. If f returns a non-nil error, the iteration stops immediately and that error is propagated back to the caller of Pages [2]. It is important to distinguish between the two types of Google Cloud client libraries for Go: - google-api-go-client (google.golang.org/api/...): This is the auto-generated library that uses the Pages method for pagination [5][1]. It is in maintenance mode [1]. - Cloud Client Libraries (cloud.google.com/go/...): These are modern, handwritten/GAPIC-based libraries that typically use an Iterator pattern (e.g., it := client.List(...), followed by it.Next()) rather than the Pages method [6][7][8].

Pass ctx to all three GCE paging requests.
FetchAllInstances, FetchMigInstances, and FetchMigsWithName receive ctx but pass context.Background() or context.TODO() to Pages. A canceled or expired caller context can therefore leave pagination running. Pass ctx to each Pages call.
