🌐 Web query:
Kubernetes admission webhook reinvocationPolicy IfNeeded webhook may be reinvoked after another webhook mutates object official documentation
💡 Result:
In Kubernetes, the reinvocationPolicy field in a MutatingWebhookConfiguration allows a mutating webhook to be called multiple times during a single admission evaluation if other admission plugins modify the object after the webhook's initial execution [1][2][3]. When set to IfNeeded, the behavior is defined as follows: 1. Reinvocation Trigger: The webhook may be invoked at least one additional time if the object being admitted is modified by other admission plugins (including other webhooks or built-in plugins) after the initial call [1][4][3]. 2. Idempotency Requirement: Webhooks using this policy must be idempotent, meaning they must be able to successfully process an object they have already admitted and potentially modified [1][3]. 3. Important Operational Notes: * The number of additional invocations is not guaranteed to be exactly one [1][5][3]. * If additional invocations result in further object modifications, there is no guarantee the webhook will be called again [1][5][3]. * Webhooks using this policy may be reordered to minimize the total number of additional invocations [1][5][3]. * To ensure an object is validated after all potential mutations are complete, official documentation recommends using a validating admission webhook or policy rather than relying on the reinvocation of a mutating webhook [1][6][3]. The policy defaults to Never, which ensures the webhook is not called more than once per admission evaluation [1][4][3].

Make NVIDIA_VISIBLE_DEVICES injection idempotent. When reinvocationPolicy is IfNeeded, Kubernetes may invoke the webhook again and append a duplicate NVIDIA_VISIBLE_DEVICES=none entry. Check for an existing entry before appending.

A lowercase makefile at the repository root overrides the project Makefile.
GNU make searches for GNUmakefile, then makefile, then Makefile, and stops at the first match. Adding this file makes every bare make <target> invocation resolve against it instead of the project Makefile. This file defines only update, dep, help, and build-image-multiplatform.
The workflows in this same change break as a result:
.github/workflows/call-e2e.yamlLine 43 runsmake e2e-env-setup, Line 70 runsmake helm-deploy, Line 74 runsmake e2e-test..github/workflows/call-release-image.yamlLine 79 and.github/workflows/call-release-image-hamicore.yamlLine 79 runmake lint_dockerfile.
None of those targets exist here, so make reports "No rule to make target". Local developer commands such as make build and make test break in the same way.
The comment at Lines 1-3 shows the shadowing is deliberate for the internal GitLab pipeline. Do not achieve it through filename precedence. Give this file a distinct name and select it explicitly, or include the project Makefile from it.

Does Kubernetes treat metadata.resourceVersion inside a strategic or JSON merge patch body as an optimistic concurrency precondition?
💡 Result:
No, Kubernetes does not treat the metadata.resourceVersion field within a strategic JSON merge patch body as an optimistic concurrency precondition [1][2][3]. Optimistic concurrency in Kubernetes is managed primarily through HTTP PUT (Update) requests [4][5][2]. In an Update operation, the client sends the full object including its metadata.resourceVersion; the API server verifies that this version matches the current version in storage, rejecting the request with a 409 Conflict if it does not [4][5][2]. Conversely, patch operations (including strategic merge, JSON merge, and JSON patch) are intended to modify resources without requiring the client to read, modify, and rewrite the entire object [6][2]. By design, patch requests do not rely on the object's resourceVersion for concurrency control [1]. Instead, the API server applies the patch to the current state of the resource [6][2]. If multiple clients attempt to patch the same resource concurrently, the server processes them sequentially, merging the changes on top of the current state [6][2][3]. Consequently, patch operations are generally not susceptible to the same optimistic locking failures as PUT operations [1].

site:kubernetes.io API concepts patch resourceVersion precondition JSON merge patch Kubernetes
💡 Result:
In the Kubernetes API, a patch request is generally designed to perform partial updates to a resource, distinct from a full PUT update [1][2]. While patch operations are typically used for changes that are not conditional on the existing data, it is possible to use the resourceVersion field to implement optimistic concurrency control during a PATCH request [1][2][3]. Key concepts regarding this pattern include: 1. Optimistic Concurrency Control: Clients can make a PATCH request conditional by providing the resourceVersion of the object they intend to modify [1][3][4]. If the resourceVersion sent in the request does not match the current resourceVersion stored in the API server (etcd), the server will reject the request with a 409 Conflict error [1][4]. This allows clients to detect and handle "lost updates" caused by concurrent modifications [1][2]. 2. Patch Types and Semantics: - JSON Merge Patch (application/merge-patch+json): Defined by RFC 7386, this approach sends a partial representation of the resource [1][2]. When combined with the existing object, the server merges the two; however, JSON Merge Patch has limitations regarding arrays, where the provided array will typically replace the entire existing array rather than merging individual elements [5][2]. - JSON Patch (application/json-patch+json): Defined by RFC 6902, this uses a list of operations (e.g., add, remove, replace) to modify the resource [1][2][3]. It provides more granular control than a merge patch [2]. - Strategic Merge Patch: A Kubernetes-specific extension (often the default for kubectl patch) that provides specialized merging behavior, such as merging lists based on patch keys [1][5][6]. While standard PATCH requests are generally intended to be applied without strict optimistic locking—meaning the last write often wins—including the resourceVersion is a best practice for clients that require strict consistency and must avoid overwriting concurrent changes [1][2][3]. In such cases, the client must implement retry logic to handle potential 409 Conflict responses [1][2].

site:github.com/kubernetes/kubernetes "resourceVersion" "Patch" "GuaranteedUpdate" patcher.go
💡 Result:
In the context of the Kubernetes apiserver and the patcher.go implementation, GuaranteedUpdate is a storage-layer function used to perform optimistic concurrency control when updating resources [1]. It ensures that updates are applied reliably by retrying if an index conflict (e.g., resource version mismatch) occurs [1]. When a patch request is processed, the patcher.go handler interacts with GuaranteedUpdate to apply changes [2][3]. The relationship between resourceVersion, Patch, and GuaranteedUpdate is critical for consistency: 1. ResourceVersion as a Precondition: If an incoming patch explicitly includes a resourceVersion, it acts as a precondition for the update [4]. If the resource version in the store does not match this provided version, the update fails with a conflict [3][4]. When a resourceVersion is specified, the internal retry mechanism avoids useless retries and will typically fail immediately upon a conflict [3][4]. 2. Patching without ResourceVersion: If no resourceVersion is specified in the patch, the system aims to apply the patch against the current state of the object in etcd [3]. Historically, this could lead to spurious conflict errors if the patch handler performed its own stale conflict detection [3]. 3. Collapsing Retry onto GuaranteedUpdate: Kubernetes improved this process by collapsing the patch conflict retry logic into GuaranteedUpdate [3]. This change ensures that when no resourceVersion is provided, the patch application is performed consistently on the object retrieved from etcd on every attempt, preventing arbitrary conflict errors caused by concurrent updates that do not affect the patched fields [3]. In summary, GuaranteedUpdate manages the retry loop for persisting objects, while the patch handler ensures that the logic for calculating the patch (and handling resourceVersion preconditions) integrates correctly with this storage-level loop to maintain data integrity and reduce unnecessary conflict errors [3][1][5].

Kubernetes official API concepts PATCH metadata.resourceVersion merge patch 409 conflict
💡 Result:
In Kubernetes, an HTTP 409 Conflict error occurs due to optimistic concurrency control [1][2]. Every Kubernetes object contains a metadata.resourceVersion field, which is an opaque string representing the internal version of that object [1][3]. The API server updates this version every time a resource is modified [3]. When a client sends a request (such as PUT or PATCH) that includes a metadata.resourceVersion, the API server compares that value against the current version stored in the cluster [4][1]. If the versions do not match—indicating that the resource was modified by another process after the client last read it—the API server rejects the request with a 409 Conflict status code [4][1][2]. This mechanism prevents lost updates by ensuring clients do not overwrite changes they are unaware of [4][1]. Key points regarding this behavior: - Client Responsibility: When using patch operations that include a resourceVersion (often implicitly via client-side libraries like client-go), it is the client's responsibility to handle 409 conflicts by implementing a retry loop [4][1]. This typically involves re-reading the latest version of the resource, applying the desired changes to the updated object, and re-submitting the request [4][1]. - Patch vs. Update: While PATCH operations are often used to reduce conflicts compared to PUT (which replaces the entire object), they can still trigger 409 errors if they specify a precondition (the resourceVersion) that is no longer current [4][2]. - Server-Side Apply: If you wish to avoid managing resourceVersions and handling 409 conflicts manually, Kubernetes provides Server-Side Apply (using the application/apply-patch+yaml content type) [5]. Server-Side Apply manages field ownership on the server and does not require the client to provide or track the resourceVersion [5]. It handles concurrent edits by tracking field managers; conflicts arise only if multiple managers attempt to modify the same field, and these can be resolved using the force query parameter [5]. For standard patch operations, if you are seeing unexpected conflicts, ensure your client is not inadvertently including a stale resourceVersion in the patch body, or implement the recommended read-modify-write retry cycle [4][1][2].

Refresh pod.ResourceVersion from the patch response.
annotateMigRuntimeInfo sends pod.ResourceVersion in each JSON merge patch. Kubernetes applies the patch and then updates the object with that resource version as a concurrency check. After the first successful patch, the API server advances the Pod resource version, but this function updates only pod.Annotations. A later call can therefore fail with 409 Conflict and abort Allocate for multi-container MIG requests.
Use the returned Pod resource version before the next call.

Project-HAMi/HAMi pkg/device/ascend/vnpu.go VNPUConfig OverwriteEnv RuntimeClassName
💡 Result:
In the Project-HAMi/HAMi repository, the fields RuntimeClassName and OverwriteEnv were added to the VNPUConfig struct within pkg/device/ascend/vnpu.go [1][2]. These additions were introduced to support improved Ascend device management in Kubernetes [1]: 1. RuntimeClassName: This configuration allows the HAMi scheduler to automatically inject a specific runtimeClassName (typically ascend-docker-runtime) into Pods that request Ascend resources [1]. This ensures that only relevant Pods use the specialized runtime required for NPU operations [1]. 2. OverwriteEnv: This mechanism is used to forcefully override the ASCEND_VISIBLE_DEVICES environment variable [1]. For containers that do not request Ascend resources, the scheduler injects ASCEND_VISIBLE_DEVICES="". This effectively hides NPU devices from containers that might otherwise mistakenly access them if the ascend-docker-runtime is present [1]. These updates were part of pull request #1738 [1][2], which modified pkg/device/ascend/vnpu.go to extend the configuration capabilities for Ascend devices [2]. Documentation also notes that users can manually configure the devices.ascend.runtimeClassName in HAMi's values.yaml to enable this automated behavior [3].

gopkg.in/yaml.v2 Unmarshal unknown fields official documentation
💡 Result:
In the gopkg.in/yaml.v2 package, unknown fields in a YAML document are ignored by default during unmarshaling [1][2][3]. The standard Unmarshal function will not return an error if the YAML input contains fields that do not have corresponding members in the target struct [1][4]. To disallow unknown fields and trigger an error when they are present, you have two primary options within v2: 1. Use UnmarshalStrict: The library provides a function called UnmarshalStrict, which is specifically designed to return an error if the YAML data contains fields that do not have corresponding struct members (or if there are duplicate mapping keys) [5][6]. func UnmarshalStrict(in []byte, out interface{}) (err error) 2. Use a Decoder: Alternatively, you can use a yaml.Decoder, which allows you to enable strict mode via the KnownFields method [7][2]. decoder:= yaml.NewDecoder(reader) decoder.KnownFields(true) // Disallow unknown fields err:= decoder.Decode(&myStruct) If you are evaluating options for newer projects, note that gopkg.in/yaml.v3 is the current version where new features and improvements are focused, though UnmarshalStrict remains available and effective in v2 for this purpose [8][2].

Preserve legacy per-chip settings or reject them explicitly.
LoadConfig decodes device-config.yaml with gopkg.in/yaml.v2.Unmarshal without strict decoding or migration. Because VNPUConfig no longer declares overwriteEnv or runtimeClassName, yaml.v2 ignores those configs[*] keys. InitDevices then applies only the top-level values to every Devices, so existing per-chip values can be silently replaced by global values or zero defaults. Add an explicit migration or reject legacy keys with a clear error. Document the schema change if rejection is intentional.

What type of PR is this?
/kind feature
What this PR does / why we need it:
Adds pod-level and container-level opt-in/out annotations for the
overwriteEnvclearing injection, on top of #2953Currently
overwriteEnvis a scheduler global device config. There is no per-pod or per-container control. These annotations give pod authors that control:hami.io/overwrite-env(pod-level, single value): overrides the device config default for all containers in the pod.hami.io/overwrite-env-containers(container-level, JSON map of container name to value): overrides the pod-level value for specific containers.Values use
strconv.ParseBoolvocabulary (true/false/1/0/t/f).Resolution order: container-level entry > pod-level value > device config.
For ascend, since each each container of each pod will go through the
dev.MutateAdmission(currently 7 times for all ascend chip type), its might be a bottlenect to decode json multiple time for the same anno. So we use a LRU cache with TTL to cache the decoded container-level JSON by itsraw content.Benchmark (7-chip webhook loop, 3-container JSON): 19667 ns/op / 119 allocs uncached → 723 ns/op / 0 allocs cached.
Which issue(s) this PR fixes:
Depends on #2953.
