Summary: X-link: https://github.com/facebook/fboss/pull/1403 The BGP OSS GitHub Actions build runs getdeps directly on a bare runner (unlike the on-diff/FBOSS builds, which run inside the CentOS Stream 9 container). getdeps fails while resolving the dependency: KeyError: 'project gcc12 has no fetcher configuration or system packages matching {distro=ubuntu, distro_vers=24.04, ...}' The manifest only declares CentOS Stream 9 RPMs (), with no ubuntu mapping and no fetcher, so getdeps cannot satisfy it on ubuntu. Both and depend on , so this blocks the whole BGP getdeps build. Add a mapping for ubuntu 24.04 (, , both available in noble's universe repo). This is purely additive — the CentOS path is unchanged — and fixes gcc12 resolution for every ubuntu getdeps consumer. Differential Revision: D111946117

What Fix a wrong FSDB path removal in . (NeighborWatcher.cpp:535) subscribes to via . But (NeighborWatcher.cpp:599) removed instead — a copy-paste from (NeighborWatcher.cpp:104), which is correct only for the config watcher. Why With enabled, calls on every daemon shutdown. The reachability watcher owns its own (NeighborWatcher.h:223/286), so the removal targeted the wrong path on the wrong manager: The subscription was never removed and leaked until process exit. A removal for , which this manager never subscribed to, was issued pointlessly. Test plan No behavioral change to the reachability logic itself; only the path removed on shutdown is corrected to match the path subscribed in . The existing suite (e.g. ) exercises the full run/stop lifecycle and continues to pass. The subscription-removal itself is only observable against a live FSDB server, so it is covered by the corrected path matching the used by the tests and the serializer.
Summary and weren't wired into the CMake target, so the CMake build was failing. This change fixes the issue. Test Plan CMake build passes.
