fix(operators): accept absolute Windows paths in @pmFromFile and @ipMatchFromFile - #1802

Conversation
…atchFromFile loadFromFile decided whether a data file path was absolute with path.IsAbs, so with the default io.OSFS root a Windows path such as C:/rules/data.txt was joined onto the rules directory and never found. With no directories to search it failed with "empty dirs" instead. path.Join also collapsed a relative ../data.txt against a Windows rules directory into a path relative to the process directory. When the root is io.OSFS, which takes OS paths, also accept filepath.IsAbs and join the directories with filepath.Join, the same io.OSFS check Parser.fsPath uses. Other fs.FS roots keep slash paths, and nothing changes on Linux or macOS.

Explanation
Not applicable. The PR changes only
internal/operators/from_file.goto fix Windows path handling in existing file-loading behavior. It adds no directive, operator, action, transformation, variable, collection, subsystem, plugin, or public API change. Bug fixes do not require an ADR. No ADR file changes are present.
Full details: Test Layer Discipline & Duplication
-
Explanation
Not applicable. The pull request changes only
internal/operators/from_file.go; it does not modify_test.go,testing/engine/, ortesting/profile/, and it does not add a test file. Therefore the test-layer duplication conditions do not apply.
Full details: Breaking Changes To Public Api & Compatibility
-
Explanation
PASS — The pull request changes only
internal/operators/from_file.go. It does not change an exported Go symbol, C API/ABI, directive or operator syntax, default configuration, or Caddyfile surface. The changed logic adds Windows absolute-path support forio.OSFSand uses OS-aware joining for relative paths (lines 18–45); this fixes previously unsupported configurations and preserves slash-based handling for otherfs.FSimplementations. No explicit breaking change condition is introduced.
Full details: Security Fix Process Compliance
-
Explanation
Not applicable. The title and contributor description frame this as a Windows path-handling correctness fix for
@pmFromFileand@ipMatchFromFile. They do not describe a vulnerability, CVE, exploit, attack sequence, payload, or security impact. The reviewed diff only changes path detection and joining ininternal/operators/from_file.go.
Full details: Owasp Security (Web & Supply Chain)
-
Explanation
No OWASP security finding is introduced. The change only selects
filepath.IsAbsandfilepath.Joinfor the configuredio.OSFSroot ininternal/operators/from_file.go:18-46. The file name comes from the SecLang operator argument (internal/seclang/rule_parser.go:193-210), not request-derived input. Absolute-path reads already existed for slash-absolute paths, and no secrets, weak cryptography, outbound requests, logging changes, or dependency changes are present.
Full details: New Dependency Scrutiny
-
Explanation
No new dependency or GitHub Action was added. The PR changes only
internal/operators/from_file.go; the authoritative diff has no changes togo.mod,package.json, or.github/workflows/*.yml. The dependency scrutiny trigger does not apply.
Full details: Install & Build-Time Code Execution
-
Explanation
PASS: The pull request changes only
internal/operators/from_file.go. The diff adds path handling withfilepath.IsAbsandfilepath.Join; it adds no installer, shell command, Dockerfile, CI workflow, Go environment setting, npm lifecycle script, or build-time download. No stated failure condition is introduced.
Full details: Secrets, Payloads & Pii In Logs
-
Explanation
PASS — the pull request changes only
internal/operators/from_file.go. The changed lines select path handling and callfs.ReadFile; they do not emit logs, stack traces, telemetry, or full request/response objects. The returned file error is pre-existing behavior, and no changed line adds payload, credential, token, cookie, base64, or audit-log output.

-
Explanation
PASS: The pull request changes only
internal/operators/from_file.go; it does not touch the repository root or.github/. The repository already containsrenovate.json, so the no-config trigger does not apply.

Review comments at @internal/operators/from_file.go:
- Around line 22-23: Update the absolute-path selection around root, osRoot, and
filepath.IsAbs to recognize Windows absolute names when root is a merged
filesystem containing an OS-backed filesystem, so names such as
C:\rules\data.txt are not searched under dirs. Add a regression case that
exercises this behavior with a merged root.

With the default

Otherfs.FSroots keep slash paths, and nothing changes on Linux or macOS.TestLoadFromFileAbsolutePathfailed on Windows before and passes now, so I did not add a test. On Windows the operators and coreruleset tests pass, and a rules file using both operators with absolute paths now loads. On Linux I ran the default, no_memoize, multiphase and no_regex_multiline tags.Part of #1140.
