Summary

Implements #1524 (Epic #1521, T3). Closes #1524.

  • GraphUpdater.reingest(paths, deleted=()): deletes what the named files contributed, re-parses them plus the files that depend on them (one level, via the graph's CALLS/REFERENCES/INSTANTIATES/IMPORTS/INHERITS edges), resolves calls in that set only (_process_function_calls(only=...)), restores every other inbound edge verbatim, flushes deferred imports, and keeps the hash cache current so a later update_repository does not re-parse the same edit. Paths outside the repo are refused. A fresh updater hydrates the package map and the registry from the graph once; a reused one runs warm.
  • The realtime watcher (realtime_updater.py) now delegates to reingest instead of deleting every CALLS edge and re-running the call pass over every parsed file.
  • New MCP tool reingest(paths, deleted?) returning {reparsed, affected, removed, elapsed_ms}; the registry keeps the updater warm across calls and reuses the one index_repository/update_repository built.
  • FunctionRegistryTrie: dotted find_ending_with cache keys are bucketed by their last segment, so an insert or delete no longer scans the whole cache (3.7 s of a hub re-ingest before).
  • evals/cgr_graph._StatefulIngestor: emulates CYPHER_AFFECTED_CALLER_PATHS, and keeps adjacency indexes so its emulated deletes and path-scoped queries cost the subtree, not the graph.
  • Docs: docs/reports/REINGEST_BENCHMARK.md (numbers below), docs/guide/realtime-updates.md, MCP tool table.

Benchmark (benchmarks/bench_reingest.py, this repo, 1,409 files / 662k lines, in-memory store, INFO logging)

Edited file Dependents reingest p50 reingest p95 whole-tree update p50
codebase_rag/services/graph_diff.py 2 194 ms 445 ms 2,934 ms
codebase_rag/parsers/utils.py (imported by 54 files) 54 3,492 ms 3,733 ms 6,992 ms

The typical edit is inside the 1 s p95 budget; a hub file is bounded by re-resolving its dependents (~60 ms each), the same rule the batch incremental path applies so that the graph after reingest equals a clean index. Re-resolving only the affected call sites in dependents (using the #1522 site properties) is the follow-up that would bring the hub case down.

Test plan

  • codebase_rag/tests/test_reingest.py: graph after reingest(edit) equals a clean full index for 7 single edits and 4 seeded composites, both with the updater that built the graph and with a fresh one; dependents/removals report; hash cache; path guard; frontend re-runs per language; the former watcher contract (project-scoped module delete, absolute-path file delete, secondary tiers, File nodes) now asserted on reingest
  • Watcher tests rewritten to the hand-off (test_realtime_updater.py, test_realtime_event_filtering.py, debounce, created-file, registry-ownership, Rust watch tests)
  • MCP tool tests (test_mcp_update_and_search.py::TestReingest)
  • ruff, ty clean; full non-integration suite: 8758 passed, 34 skipped, 1 xfailed
  • Memgraph integration tests (CI)

Note on the merge of main (fce057e0)

main was merged in to clear a conflict and to pick up _assert_parses, which fixes this PR's base-install failure (test_import_rewrite.py asserting result.parses is True where a base install has no Rust or Go grammar and reports None). That fix arrived on main with #1544; it is not new work here.

One thing worth flagging for review, because the conflict resolution was wrong the first time and every cheap check passed:

graph_updater.py's conflict was between main's inline sequence in run() and this branch's extracted _resolve_deferred_definitions(rehydrate) helper (the helper is the point of #1524 - run() and reingest() need the same deferred stages). Resolving in favour of the helper preserved an identical call multiset and still shipped a regression: main's commit 1ba25c7e (#1552) requires resolve_deferred_cpp_methods to run after _rehydrate_registry_from_graph, because an out-of-class method's class is only known once the registry is read back from the graph. This branch predated that commit, so the helper carried the pre-fix order and the merge silently reverted it.

Symptom: 3 failures, each registering one C++ method under two qualified names (proj.shape.Shape.area beside proj.shape.h.geo.Shape.area) - the module-anchored fallback qn appearing because the class was not yet known.

  • test_cpp_incremental_out_of_class_method.py::test_incremental_reparse_registers_out_of_class_method_once[derived.cpp]
  • the same test [derived.h]
  • test_incremental_inbound_deferred_targets.py::test_incremental_reindex_keeps_inbound_calls_to_deferred_targets[cpp-header-declared-method]

Fixed by moving the cpp_methods / cpp_containment / macro-calls block after rehydration so the order matches main's exactly. Verified as a pure reorder (call multiset unchanged), and mutation-checked: restoring the old order reproduces exactly those three failures.

Full unit suite on the merge: 8974 passed, 0 failed, 38 skipped, 1 xfailed. The 257 errors are all tests/integration/ Docker connection failures at fixture setup (no local Docker), not test failures.

Merge Risk: 🟡 Moderate · up to a53ba

Scoped re-ingestion should not merge until incomplete index state survives process restarts; otherwise a restart after a failed graph mutation can allow later re-ingestion to treat partial or stale graph data as authoritative.

Full details: Description check

Explanation

The description includes a detailed summary, related issue references, implementation details, benchmark results, and a test plan. It omits the template's Type of Change and Checklist sections, but the core required information is present.

Full details: Linked Issues check

Explanation

The PR implements the scoped re-ingest API, MCP tool, watcher integration, benchmark harness, graph-equivalence tests, and deferred C++ resolution ordering required by #1524. The typical edit meets the latency target at 445 ms p95, but the reported hub-file case reaches 3,733 ms p95, so the under-one-second acceptance criterion is not met for all tested one-file edits.

Resolution

Reduce scoped re-ingestion latency for hub files so the one-file re-ingest path meets the <1 second p95 acceptance criterion, or provide issue-approved evidence that the target applies only to typical edits and document the limitation explicitly in the linked issue and PR acceptance results.

Full details: Out of Scope Changes check

Explanation

The changes remain related to #1524. The benchmark harness, cache optimization, stateful ingest support, documentation, watcher updates, MCP integration, and tests directly support scoped re-ingestion and its performance requirements.

Greptile Summary

The change adds scoped file re-ingestion that preserves dependent graph relationships and protects the MCP graph lifecycle during deletion, wipe, update, and re-ingestion failures.

The following previously reported issues were disproved by executed checks on the current code:

  • Deferred C/C++ inheritance, imports, method containment, and override relationships are preserved when re-ingesting each relevant fixture file.
  • Project deletion and database wiping do not leave a retained updater available for later scoped re-ingestion.
  • Scoped re-ingestion after a cleared graph refuses until the project is indexed again instead of partially rebuilding an empty graph.
  • C/C++ re-ingestion in LIBCLANG mode runs the frontend before parsing the changed file.
  • A failed embedding cleanup after graph wiping does not retain the warm updater.
  • Failed repository updates and failed scoped re-ingestion mark the graph incomplete and require a successful repository update before scoped work resumes.
  • Failed project deletion and database cleanup invalidate the updater before the potentially mutating operation begins.

No actionable blocking issue remains.

Confidence Score: 5/5

No blocking failure remains.

Focused C++ graph and MCP lifecycle checks exercised the previously failing relationship preservation, destructive-operation, failure, retry, and recovery paths and observed the expected protected behavior.

T-Rex T-Rex Logs

What T-Rex did

  • The parameterized C++/MCP test suite ran and reported 3 passed in 10.38s, after touching derived.h, derived.cpp, and base.h.
  • The stale-updater MCP flow was exercised: a before/failure capture showed failing state and passing tests, the after/success capture showed those tests passing after a destructive operation, and the regression suite later confirmed all 17 MCP reingest cases pass.
  • The validation guard logic was exercised to prevent reingest when the graph is incomplete or the project is no longer indexed.
  • The frontend ordering behavior was validated: the frontend now runs before parse, aligning with full-index ordering, in a focused suite that passed.
  • The recovery path for updater state was demonstrated: an embedding-clear failure cleared the updater, recovery installed a new updater, and reingest completed successfully.

before running the benchmark and calculating statistics. Update the reingest
flow around samples and reingest_max_ms so invalid zero or negative values are
rejected clearly, while preserving normal processing for positive iterations.
- Around line 101-103: Update target validation in the benchmark flow to reject
any resolved target that is not contained within the resolved corpus directory
before reading or writing it. Apply this containment check alongside the
existing is_file check, preserving valid in-corpus targets and preventing
_toggle_edit from modifying external files or target.relative_to from failing
later.
- Around line 147-151: Update the cleanup around the target restoration in the
benchmark to capture the target file’s original timestamps before modification
and restore them with os.utime() after write_bytes(original). Preserve the
existing stale cache-file removal, and ensure both access and modification times
are restored.

In `@codebase_rag/graph_updater.py`:
- Around line 2816-2817: Update reingest() before its _process_single_file loop
to apply self._delombok_overlay and call _register_generated_sources(), then
pass the overlaid source bytes as source_bytes when reparsing each path so
DefinitionProcessor.process_file() does not reread checked-in content.

In `@codebase_rag/mcp/tools.py`:
- Around line 94-97: Clear the cached _live_updater in both delete_project and
wipe_database after the corresponding graph state is deleted, so later reingest
operations create fresh registries and rehydrate the graph instead of reusing
stale state.

In `@docs/guide/mcp-server.md`:
- Line 66: Update the reingest latency wording in docs/guide/mcp-server.md lines
66-66 to qualify that speed depends on the number of affected dependents rather
than promising sub-second performance. Update docs/guide/realtime-updates.md
lines 67-68 to replace “handful of files” with “affected dependents” while
retaining the hub-case caveat.

Clear _live_updater before deleting the project graph.

If a prior index populated _live_updater, then a later index_repository deletes the graph and updater.run() fails, the old updater remains cached. A later reingest skips the indexed-project check and uses stale definitions against the deleted graph.

Set _live_updater = None immediately before self.ingestor.delete_project(project_name). Add a regression test for a failed re-index followed by reingest.

…inbound restore (#1524)

# Conflicts:
#	evals/cgr_graph.py
…ped paths

Re-ingest hashed re-read bytes and saved the cache with a fresh mtime,
which hid every edit the caller did not name from the next update. It
now hashes the bytes it parsed, restores the cache's previous mtime and
fails closed if the restamp fails. Paths the ignore rules exclude are
skipped and reported instead of indexed, the MCP tool builds its updater
with the same ignore sets, the stale watcher step box is rewritten and
the orphaned recalc constants are removed.
…pped on error

A directory named in paths or deleted fell into the gone set, where the
delete queries match nothing, so the report claimed it was removed while
the graph stayed untouched; it is now refused like a path outside the
repo. The ignore check on the deleted branch gains its own test cases,
and the MCP error result carries the skipped field the success result
has.
The directory refusal applies to paths only, where present or gone is
inferred from disk. An explicit deletion is an instruction, and the
watcher's DELETE event can land after a same-named directory appears, so
that channel deletes the stale Module as it did before.
…fusals, document what reingest leaves to the full update

A failed rebuild after index_repository's delete left _live_updater
pointing at the removed graph, so a later reingest bypassed the
not-indexed guard and resolved against dead definitions; it is cleared
right after the delete. The watcher's debounce callback now logs a path
reingest refuses instead of dying on the timer thread. The tool
description and the benchmark report state that finding edges and
URL-to-endpoint links are rebuilt only by update_repository (#1670).
The eval store loses a duplicate match arm and a shadowed relation set
left by the rebase, and the mtime test pushes both edits past the
cache stamp so a coarse clock cannot make it flaky.
…orted router handlers

A warm updater's reingest() left _is_full_build set from the initial build,
so a failed inbound-edge capture was swallowed instead of aborting. Reset
the flag at the top of reingest().

When only a mount-prefix module is re-ingested, the endpoint pass now also
rehydrates the handlers of the router modules it imports, so their
endpoints are re-emitted under the edited prefix instead of being dropped.

List IMPLEMENTS among the edges restored by the benchmark doc.
…es them transitively

The scoped re-ingest pulled router modules in through the import
processor's map, one level deep, and attributed rehydrated handlers
against that partial set. Under a package root a sibling 'import routes'
is recorded bare there and was never found; a mount chain two imports
away was never loaded; and a package module pulled in by an import stood
in for its unloaded children, so unrelated routers' handlers lost their
EXPOSES edges and came back with no prefix.

Resolve the imports from the ASTs with the router registry's own
resolver, close the set transitively, and attribute handlers against
every module the graph knows before filtering to the scoped set.
The replacement updater was registered only after run() and the flush
succeeded, so an update that failed part way left the previous updater
in place and a later reingest resolved against definitions the partial
update had already replaced. The retained updater is dropped before the
run mutates the graph; a reingest after a failed update hydrates from
the store.
A failed update_repository or index_repository leaves a partial graph.
Dropping the retained updater alone let the next reingest hydrate a
fresh one from that graph and treat its missing and stale definitions
as authoritative. The registry now marks the graph incomplete from the
moment a run starts mutating it until it completes, and reingest refuses
with a message naming update_repository as the recovery step.
…ingest that dies mid-run

The incomplete flag went on after the initial flush of update_repository
and after the project delete of index_repository, both autocommit writes
that can fail part way with the retained updater still registered. It
now goes on before the first write of either. A reingest that raises
after its refusal checks may have deleted the affected subtrees without
rebuilding them, so that path drops the retained updater and marks the
graph incomplete too; a refusal (ValueError, raised before any write)
leaves the updater valid.
… keep their clean-index qns

After #1573 the batch incremental path re-parses changed files in walk
order because the first same-stem sibling parsed claims the bare module
qn. The scoped path parsed the edited file before its dependents, so a
header re-ingested with its source file took the source's qn and the
deferred relationships landed under the wrong module. Sort the re-parse
set the way the walk yields it.
A stem with a sibling added or deleted by the call is in flux: its
on-disk survivors re-parse unseeded, in walk order, and the module-qn
map is seeded from the graph for everything else, so a fresh updater
sees the taken qns before it parses and the bare qn goes to the file a
clean index gives it. Without this a sibling added through the scoped
path merged into the survivor's Module, and a deleted winner left the
survivor with its suffixed qn.
…d reports re-parsed survivors

A failed module-path read left the seed empty and let a modified loser
sibling claim the winner's bare qn; the call now aborts before any
delete, as the inbound-edge capture does. Survivors of a stem in flux
are reported as affected. The eval store answers the project module-path
query so the seed is exercised by the tests: a modified loser sibling on
a fresh updater and a deleted module's rehydrated qn are pinned.
…CP tool's updater

Everything before the inbound-edge capture only reads the graph. A
failure there (the module-path read, the capture itself) now raises
ReingestAborted, and the MCP tool treats it like a refusal: the retained
updater stays, the graph is not marked incomplete, and the call can
simply be retried instead of forcing a full update.
…e their first write

Both invalidated the retained updater only after the delete returned, so
a delete that failed part way left it describing graph data that was
already gone, with the project possibly still listed. The updater is
dropped and the graph marked incomplete before the write; a completed
delete clears the flag and the not-indexed guard covers the rest.

reconstruction: persist per-project completion status, or conservatively require
a full update after restart until a completed index is proven. Update
update_repository and reingest to honor this state, and add a regression test
