fix: address 12 confirmed findings from codebase audit#1791
Conversation
Systematic audit found 30 potential issues from agent-authored code. After parallel verification by 11 subagents, 13 were confirmed real, 8 were by-design, 5 were won't-fix, and 5 were false positives. This commit fixes all 12 actionable confirmed findings. **High severity:** - Fix OtherStr panic: OTLP sink crashed on non-string attribute types (e.g., hash() UDF returning UInt64). Replaced unreachable!() with array_value_to_string(). Removed dead str_value() function. (#7) - Fix silent struct drop: non-conflict Struct columns now log a warning before being skipped, matching the resource struct behavior. (#6) **Medium severity:** - Fix scanner contract drift: SCANNER_CONTRACT.md said "no escape decoding" but implementation decodes since PR #885. Updated doc. (#19) - Deduplicate calendar math: made core's Kani-verified days_from_civil public; arrow's wrapper now delegates instead of reimplementing. (#21) - Centralize metadata keys: added METADATA_RESOURCE_KEY and METADATA_RESOURCE_PREFIX constants to field_names.rs, replacing 15 bare string literals across 4 files / 3 crates. (#15) - Add TypedColumn::Bytes variant: OTAP bytes attributes now round-trip as BinaryArray instead of being hex-encoded to strings. (#16) **Low severity:** - Deduplicate WELL_KNOWN arrays: star_schema.rs now delegates to field_names::matches_any() instead of maintaining a local copy. Added logfwd-types dependency to logfwd-arrow. (#13) - Centralize _raw column name: added field_names::RAW constant. (#12) - Extract MAX_REQUEST_BODY_SIZE: shared constant in receiver_http.rs replaces 3 independent definitions. (#27) - Import DEFAULT_RETRY_AFTER_SECS: otap_sink and arrow_ipc_sink now import from http_classify instead of redefining. (#29) - Name timing defaults: pipeline build.rs and input_build.rs now use named constants instead of inline unwrap_or literals. (#30) - Add timestamp diagnostic: tracing::debug!() on timestamp parse fallback for operator visibility. (#1) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

ApprovabilityVerdict: Needs human review This PR addresses multiple audit findings with a mix of mechanical refactoring (constant consolidation, field name centralization) and substantive runtime behavior changes: binary attributes now preserve binary format instead of hex-encoding, invalid timestamps return None instead of 0, and new logic prevents attribute columns from overwriting fact columns. The scope of behavioral changes warrants human review. You can customize Macroscope's approvability policy. Learn more. |

Pull request overview
This PR applies a set of targeted fixes from a codebase audit, focusing on correctness hardening (avoiding panics), consistency (shared constants / centralized field-name keys), and contract alignment between scanner behavior and developer docs.
Changes:
- Centralized common identifiers/constants (e.g.,
_raw, Arrow metadata keys, HTTP body size limits, pipeline/input defaults). - Hardened OTLP encoding paths to avoid crashes when encountering non-string Arrow types (e.g.,
hash()UDF output), and added more diagnostics for skipped/invalid data. - Updated Arrow star-schema conversion to deduplicate calendar math and to round-trip OTAP bytes attributes as Binary rather than hex strings; updated scanner contract docs accordingly.

In `@crates/logfwd-arrow/src/star_schema.rs`:
- Around line 1757-1767: The TypedColumn::Bytes scatter currently clones each
Vec<u8> per matching row (in the TypedColumn::Bytes arm where rid_to_val =
collect_resource_template_values(...) and writes into flat_cols[col_pos].1),
causing O(rows × payload) allocations; change the approach to avoid per-row
cloning by storing shared buffers keyed by template ID (e.g., Arc<[u8]> or
&Arc<Vec<u8>> references) in rid_to_val and write those shared handles into
flat_cols (or keep the per-template bytes in rid_to_val until final array
materialization), updating collect_resource_template_values and the code that
consumes flat_cols accordingly so the hot path does not allocate per record;
apply the same fix to the similar Bytes scatter at lines around the 1866-1879
region.
In `@crates/logfwd-output/src/otlp_sink.rs`:
- Around line 759-763: The sink currently treats Binary/LargeBinary
(TypedColumn::Bytes) values as OtherStr and calls array_value_to_string() which
allocates and loses binary semantics; update OTLP support by adding a
bytes_value field (e.g. ANY_VALUE_BYTES_VALUE) to AnyValue in
crates/logfwd-core/src/otlp.rs and extend ResourceValueRef (or equivalent) to
carry owned bytes, then change the match arm at Self::OtherStr (and the parallel
handling around array_value_to_string) to detect binary arrays
(TypedColumn::Bytes / Binary/LargeBinary) and return a bytes variant that uses
the raw slice/owned bytes without calling array_value_to_string().
Alternatively, if you prefer filtering, ensure Binary/LargeBinary columns are
removed before reaching otlp_sink.rs so they never hit Self::OtherStr; pick one
approach and implement consistent handling across the encode path (otlp.rs
AnyValue, ResourceValueRef, and the match in otlp_sink.rs).
In `@crates/logfwd-runtime/src/pipeline/build.rs`:
- Around line 22-27: The new crate-visible constants (DEFAULT_WORKERS,
DEFAULT_BATCH_TARGET_BYTES, DEFAULT_BATCH_TIMEOUT, DEFAULT_POLL_INTERVAL,
DEFAULT_IDLE_TIMEOUT, DEFAULT_CHECKPOINT_FLUSH_INTERVAL) lack behavior-focused
/// doc comments; add short doc comments above each constant that describe its
purpose, units/format (e.g., bytes, milliseconds/seconds), where it is used
(e.g., batching, polling, idle shutdown, checkpoint flushing), and any
behavioral effect or guarantees (e.g., target batch size triggers flush, timeout
thresholds), so consumers of the crate understand the default behavior and
units.

In `@crates/logfwd-output/src/otlp_sink.rs`:
- Line 1200: Update the debug log string in otlp_sink.rs to use "unparsable"
instead of "unparseable": locate the log call that emits "timestamp parse
fallback: event_time omitted for unparseable value" and change the literal to
"timestamp parse fallback: event_time omitted for unparsable value" so it
matches the lint/logging terminology; ensure any matched unit tests or snapshots
expecting the old wording are updated accordingly.
- Around line 766-771: AttrArray::value_ref currently turns OtherStr into
ResourceValueRef::OwnedStr by calling format_non_string_attr_value which
allocates a String per row; to avoid per-record allocations change the contract
so OtherStr returns a borrowed slice instead (reuse ResourceValueRef::Str or add
a borrowed variant like ResourceValueRef::StrRef) and update
format_non_string_attr_value to return &str (or write into a caller-provided
scratch buffer reused across rows) so no heap allocation occurs in value_ref;
alternatively, if changing ResourceValueRef is undesirable, change the
resource-group key construction to avoid cloning the key on lookup by using
HashMap::entry and only allocate when inserting the new owned key—adjust the
functions value_ref, ResourceValueRef variants, format_non_string_attr_value,
and the grouping loop that builds/looks up keys to implement one of these
non-allocating approaches.
