Apply managed-repository filtering in --from-file mode.
generateJobsFromFile loads managed-repository configuration but never calls skipRepoBranch. A managed branch passed with --from-file is generated and written, although this flag must leave managed output untouched. Check skipRepoBranch after metadata validation and return before resolution or writing.
This matches the stated managed-repository contract: managed entries are skipped and left untouched.

Go 1.25 os.File.Close documentation returns error close failure
💡 Result:
In Go, including version 1.25, the os.File.Close method returns an error if the underlying file close operation fails or if the method has already been called on the same file instance [1][2][3]. The official documentation explicitly states: Close will return an error if it has already been called [1][2]. When working with writable files, it is highly recommended to check the error returned by Close [4]. Because operating systems may cache data in memory and only flush it to storage during the close operation, an error returned by Close can indicate that data was not successfully written [4]. A common pattern for handling this is to use a deferred call to Close to ensure resources are released, while also explicitly calling and checking the error of Close at the end of the operations, handling the "already closed" error if necessary [4][5]. Example pattern: func example (err error) { f, openErr:= os.OpenFile("file.txt", os.O_WRONLY|os.O_CREATE, 0666) if openErr!= nil { return openErr } // Ensure resource cleanup, ignoring the error from the deferred call // if the explicit call already succeeded. defer f.Close if _, writeErr:= f.WriteString("Hello"); writeErr!= nil { return writeErr } // Explicitly close and check for errors return f.Close }

Handle the temporary-file close error.
os.File.Close can return an error. If tmp.Close() fails, remove tmpPath and return a wrapped error before writing or renaming the temporary file.

Official Go strconv.Atoi documentation range overflow returns max int ErrRange
💡 Result:
Yes, the Go function strconv.Atoi does return a strconv.ErrRange error when the provided string represents a value that is outside the range of the platform's int type [1][2][3]. When strconv.Atoi encounters a value that cannot be represented by the signed int type on the current architecture, it returns: 1. The maximum magnitude integer that fits within the target type (either math.MaxInt or math.MinInt, depending on the sign of the input) [2][4]. 2. A wrapped error, where the underlying error is strconv.ErrRange [2][4]. Because Atoi is implemented as a wrapper around strconv.ParseInt(s, 10, 0) [1][5], it inherits the behavior described in the documentation for ParseInt: if a value cannot be represented by a signed integer of the given bit size (0 in the case of Atoi, which defaults to the system's int size), it returns the maximum magnitude integer for that type and the ErrRange error [2][4]. You should always check the returned error to ensure it is nil before using the result [6][3].

Reject release numbers that overflow int.
releaseVersionFromBranch ignores strconv.Atoi errors and returns ok=true. An out-of-range component can reach versionAtLeast as a saturated int, causing an invalid branch to be classified as managed. Return ok=false when either conversion fails.

In --from-file mode org/repo come from YAML metadata rather than a trusted directory structure, so a value like "../../etc" could otherwise escape jobDir via filepath.Join. Addresses a CodeRabbit review comment on PR openshift#5375. Co-authored-by: Cursor <cursoragent@cursor.com>
Introduces a YAML-based managed-repos config (pkg/prowgen.ManagedReposConfig) so ci-operator-prowgen can skip repos/branches that are managed elsewhere (e.g. onboarded onto EFS), replacing ad-hoc exclusion flags with a single org/repo -> branch predicate shared by auto-config-brancher. Also adds a --from-file mode that generates jobs for a single ci-operator config and writes them atomically (jc.WriteBranchToDir), so a caller (a postsubmit invoking prowgen per-changed-file) can safely update job files on a volume that's read concurrently by live Prow components, without touching the existing --from-dir/--to-dir path. That mode intentionally does not consult --managed-repos-config itself: the caller is expected to have already decided which org/repo@branches it owns before ever invoking prowgen. org/repo values are validated before use in WriteBranchToDir since they come from YAML metadata rather than a trusted directory structure.

Do not load managed-repository configuration in file mode.
--from-file is documented as not consulting --managed-repos-config. This code still reads and validates that file before dispatch. If a file-mode caller passes a stale or unavailable managed-repository path, generation fails although the configuration is not used. Load it only when o.fromFile == "".

Remove stale branch output when generation produces no jobs.
WriteBranchToDir only writes files derived from generated; it does not delete files and does not receive info.Branch. If a config removes its final postsubmit, the existing branch postsubmit YAML remains in --to-dir, so Prow continues to run the removed job. Extend the branch-scoped writer to reconcile and atomically remove obsolete files for info.Branch.

generation flow around WriteBranchToDir to reconcile output for info.Branch,
including atomically removing stale branch files when generated contains no jobs
or omits previously generated jobs. Extend the branch-scoped writer’s inputs and
implementation as needed to identify the branch and delete obsolete files while
preserving current generated output.

Summary
Part of the plan to move generated Prow jobs off of
ci-operator/jobs/inopenshift/releaseand onto EFS, without disrupting the existing git-based flow.pkg/prowgen.ManagedReposConfig, a YAML config mappingorg/repoto which of its branches are "managed elsewhere" (e.g. already onboarded onto EFS):allBranches: true— the whole repo.fromRelease: "4.22"— onlyrelease-X.Ybranches at/after that version (non-release branches likemain, and older release branches, are unaffected — supports mixed mode during a repo's migration).branches: [...]— explicit extra managed branches.excludeBranches: [...]— escape hatch that always wins.ci-operator-prowgengains--managed-repos-config <path>. Managed org/repo@branch entries are skipped entirely: no jobs generated for them, and their existing files under--to-dirare left untouched (not pruned) since another process now owns them.auto-config-brancherpasses--managed-repos-configthrough to the prowgen step when configured.--from-file <path>mode toci-operator-prowgenthat generates jobs for a single ci-operator config file (org/repo/branch read from its ownzz_generated_metadata) and writes them via a newjc.WriteBranchToDir, which only touches that file's own branch and writes atomically (temp file + rename) viajc.WriteToFileAtomic. This is scoped to--from-fileonly — the existing bulk--from-dir/WriteToDirpath is unchanged and still writes non-atomically, since it targets a git checkout that gets committed rather than a volume read concurrently by live Prow components.Made with Cursor
Summary
ci-operator-prowgen. Operators can skip all branches, selected branches, or release branches from a minimum version. Exclusions take precedence.--managed-repos-configand passes it throughauto-config-brancher. Managed branches are neither generated nor pruned, which preserves externally managed jobs.--from-filefor postsubmit workflows that generate jobs from one ci-operator configuration. The command atomically updates only that configuration’s branch and leaves other branch files unchanged.
