Description

Checks if the root of the glob path is a symlink and adds it to inode tracking if it is. This fixes a bug where the symlink's target directory inode isn't tracked.

Checklist

  • Patch has a change log entry OR does not need one.
  • Investigated and inspected CI test results
  • Updated documentation accordingly

Automated testing

  • Added unit tests
  • Added integration tests
  • Added regression tests

If any of these don't apply, please comment below.

Testing Performed

There is an integration test form @robbycochran. Unit tests were also added. CI is sufficient.

Summary by CodeRabbit

  • Bug Fixes
    • Recursive scans now correctly process configured directories accessed through symlinks.
    • Changes inside symlinked directory roots are tracked, including newly created direct children.
    • Glob-based scans now handle literal, wildcard, relative, and root paths more reliably.
    • Scan results include both the resolved target path and the configured symlink path for clearer reporting.

📝 Walkthrough

Walkthrough

The scanner now detects symlink prefixes in glob patterns and includes them in recursive scans. Unit and integration tests cover path forms, root cases, and direct-child creation through a configured relative symlink.

Changes

Symlink-root recursive scanning

Layer / File(s) Summary
Pattern-root detection and unit coverage
fact/src/host_scanner.rs
The scanner derives literal prefixes from glob patterns and identifies symlink roots. Table-driven tests cover wildcard, literal, relative, and root-directory paths.
Recursive scan integration
fact/src/host_scanner.rs, tests/test_path_symlink.py
scan_inner adds detected symlink roots to glob results. Integration coverage verifies creation events through a configured relative symlink.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to f271b

The change adds symlink-root handling for recursive glob scanning, with no concrete merge-blocking risk established in the supplied evidence.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Wait for reload completion before creating the file.

SIGHUP reloads configuration asynchronously. sleep(0.5) can finish before the scanner applies the new path and completes its scan. The child creation event can then be missed intermittently.

Wait for an observable completion condition, such as an incremented scan metric, before creating file_via_link.

Based on learnings, avoid sleeps in automated testing when possible.

This fix only works if the pattern is explicitly landing on a symlink. Any other symlink that is found as part of a glob expansion will still not be followed. That means this fix suffers from the same short-comings I pointed out in #1655 (comment)

@robbycochran, @JoukoVirtanen, can we stop trying to blindly push code and have a discussion about what the actual problem is and how to address it first?
