feat(caib): accept /workspace paths in --workspace builds - #564
Conversation
📝 WalkthroughWalkthroughWorkspace builds now rewrite workspace manifest references, materialize or hydrate workspace files, record upload metadata, and coordinate upload completion through build API and controller changes. ChangesWorkspace build support
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The change enables workspace-backed builds, but the current implementation can falsely fail valid files, fail large transfers, copy data through symlink escapes, exceed platform metadata limits, and still reject some workspace references in default builds. These concrete correctness, availability, and security risks mean the PR is not merge-ready until they are addressed. Sequence Diagram(s)sequenceDiagram

Remove staged workspace files after the upload completes.
Line 36 creates a temporary directory, but this method returns no cleanup function or directory handle. The caller receives only file paths, so it cannot remove the directory after handleFileUploads.
Each successful or failed workspace upload leaves copied workspace content on the client filesystem. Return a cleanup function and call it after the upload attempt completes.

Kubernetes official source total annotation size limit 256 KiB TotalAnnotationSizeLimitB ValidateAnnotations
💡 Result:
In Kubernetes, the total size of all annotations attached to a single object is strictly limited to 256 KiB [1][2]. This limit includes the combined size of all annotation keys and their corresponding values [3][1][2]. The technical implementation of this constraint is found in the Kubernetes source code within the k8s.io/apimachinery package [3][4][5]. The constant TotalAnnotationSizeLimitB is defined as 256 * (1 << 10), which equals 262,144 bytes [3][6]. The ValidateAnnotations function utilizes ValidateAnnotationsSize to enforce this cap [3][7]: 1. The ValidateAnnotations function serves as the primary validator for object metadata annotations [3][7]. 2. The ValidateAnnotationsSize helper function iterates through the map of annotations, calculating the sum of the byte lengths of every key and every value [3][7]. 3. If the calculated totalSize exceeds TotalAnnotationSizeLimitB (262,144 bytes), the validation fails, typically resulting in an error message such as "metadata.annotations: Too long: must have at most 262144 bytes" [3][7][2][8]. This limit is a common source of errors during kubectl apply operations when using client-side apply, because the kubectl.kubernetes.io/last-applied-configuration annotation stores a full JSON copy of the object's manifest, which can quickly grow to exceed the 256 KiB cap for large or complex resources [2]. Switching to server-side apply is the recommended strategy to avoid this issue [2].

Do not identify an exec failure from file bytes.
If a workspace file ends with a line such as [exec failed: fake], execFailedTrailer returns an error for valid file content. add_files payloads must preserve arbitrary bytes.
Return the command status through the ExecWorkspace response protocol, then remove payload-content error detection.

Reject symlink escapes during workspace hydration. workspaceRelPath rejects lexically external paths, but workspaceListPython accepts symlink files and copyFileFromPodToWriter follows them with cat. Validate each resolved source with os.path.realpath before copying and add failing Go tests first.

A fixed 2-minute hydrate timeout cannot converge for large workspace files.
ensureWorkspaceHydrate wraps the whole transfer in workspaceHydrateTimeout. HydrateWorkspaceForImageBuild copies every file from the start on each call, because no per-file progress is recorded. If the total transfer needs more than 2 minutes, every attempt hits the deadline, the error counts as transient, and after maxWorkspaceHydrateAttempts the build moves to Failed. Large add_files payloads therefore always fail.
Scale the timeout with the upload timeout, or apply the timeout per file, or skip files that already exist on the upload pod so retries make progress.
Also applies to: 568-572

ensureWorkspaceHydrate and HydrateWorkspaceForImageBuild so large workspace
transfers can make progress across retries instead of always failing at the
fixed workspaceHydrateTimeout; scale the overall timeout with the upload
timeout, apply timeout per file, or skip files already present on the upload
pod. Preserve retry handling while ensuring successful file copies are not
restarted unnecessarily.

The inner loop authors manifests against the workspace filesystem. build-dev treated /workspace add_files as local laptop paths and could not use file:///workspace repos.
Copy add_files from the running workspace onto the upload PVC as src/... and point file:///workspace repos at the workspace HTTP server.
