worker, stdio isolation, and log stream Worker response correlation now matches by request_id; notifications are queued separately. Process-group cleanup caches pgid at start and signals the group even after leader exits. Operation-scoped repair only touches the named step. Production stdio_server.main() installs StdioIsolation permanently; per-handler redirect_stdout_to_stderr removed from rpc_dispatch (now a no-op under permanent isolation). LogStreamReader archives unknown marker events as raw data instead of silently discarding them. Archive I/O errors are surfaced through state.error. --- chipcompiler/runtime/log_stream.py | 27 ++--- chipcompiler/runtime/rpc_dispatch.py | 5 +- chipcompiler/runtime/stdio_isolation.py | 6 +- chipcompiler/runtime/stdio_server.py | 17 ++- chipcompiler/runtime/worker.py | 106 +++++++++++------ chipcompiler/tools/ecc_dreamplace/module.py | 4 +- test/runtime/test_log_stream.py | 67 +++++++++++ test/runtime/test_stdio_server.py | 59 +++++----- test/runtime/test_worker.py | 122 ++++++++++++++++++++ 9 files changed, 314 insertions(+), 99 deletions(-) diff --git a/chipcompiler/runtime/log_stream.py b/chipcompiler/runtime/log_stream.py index 63dd1bc4..c6c43505 100644 --- a/chipcompiler/runtime/log_stream.py +++ b/chipcompiler/runtime/log_stream.py @@ -34,7 +34,7 @@ def emit_step_marker(event: str, step: str, tool: str) -> None: sys.stdout.flush() sys.stderr.flush() payload = json.dumps({"event": event, "step": step, "tool": tool}, separators=(",", ":")) -

+0800 Subject: [PATCH 03/52] fix: correct remaining P0 defects in worker correlation, escalation, repair, and marker matching Response correlation: separate id-keyed pending-response store from notification queue. read_response checks pending store before reading stdout. All decoded messages in every batch are preserved. Process-group escalation: check group liveness (killpg signal 0) after each signal+wait. Continue SIGTERM/SIGKILL even when proc.wait() has already returned but the group still has live members. Flow repair: require active_step (no unscoped fallback). Check json_write return value and raise OSError on write failure. Log stream: track active step/tool in state. Only a matching end marker closes the archive. Mismatched end markers are archived as raw data without changing state. --- chipcompiler/runtime/log_stream.py | 11 ++- chipcompiler/runtime/worker.py | 64 ++++++++++------ test/runtime/test_log_stream.py | 37 +++++++++ test/runtime/test_worker.py | 117 ++++++++++++++++++++++++----- 4 files changed, 188 insertions(+), 41 deletions(-) diff --git a/chipcompiler/runtime/log_stream.py b/chipcompiler/runtime/log_stream.py index c6c43505..34c61d68 100644 --- a/chipcompiler/runtime/log_stream.py +++ b/chipcompiler/runtime/log_stream.py @@ -63,6 +63,8 @@ class LogStreamState: tail_bytes: bytes = b"" archive_file: BinaryIO | None = field(default=None, repr=False) + active_step: str | None = None + active_tool: str | None = None bytes_archived: int = 0 steps_seen: list[str] = field(default_factory=list) error: Exception | None = None @@ -143,10 +145,17 @@ def _process_buffer(self, buf: bytes) -> bytes: def _handle_marker(self, marker: StepMarker, raw_line: bytes) -> None: if marker.event == "begin": self._close_archive() + self._state.active_step = marker.step + self._state.active_tool = marker.tool self._state.steps_seen.append(marker.step) self._open_archive(marker.step, marker.tool) elif marker.event == "end": - self._close_archive() + if marker.step == self._state.active_step and marker.tool == self._state.active_tool: + self._close_archive() + self._state.active_step = None + self._state.active_tool = None + else: + self._emit_data(raw_line) else: self._emit_data(raw_line) diff --git a/chipcompiler/runtime/worker.py b/chipcompiler/runtime/worker.py index 8e9ef66d..5f39db95 100644 --- a/chipcompiler/runtime/worker.py +++ b/chipcompiler/runtime/worker.py @@ -42,6 +42,7 @@ def __init__(self, worker_argv: list[str]): self._pgid: int | None = None self._decoder = ContentLengthDecoder() self._notifications: deque[dict] = deque() + self._pending_responses: dict[int, dict] = {} def start(self) -> subprocess.Popen: self._process = subprocess.Popen( @@ -81,9 +82,13 @@ def send_request(self, method: str, params: dict, request_id: int = 1) -> None: def read_response(self, request_id: int = 1) -> dict: """Read the next RPC response matching request_id. - Notifications (messages without an 'id' field) are queued internally. + Checks the pending-response buffer first (for out-of-order delivery). + Non-matching responses are stored by id for later retrieval. + Notifications (no 'id') are queued separately.

Invalid envelopes raise WorkerProcessError. Process-group escalation: replace proc.wait()-based escalation with group-liveness polling via os.killpg(pgid, 0) with deadlines. After each signal, wait for the group to exit before escalating. Descendants that handle SIGTERM gracefully are not SIGKILL'd. Log stream state machine: only accept begin markers while inactive (no active step). A begin while active is archived as raw data without state change. Close archive handle properly on write failure. Step marker emission: EngineFlow.run_step() emits begin/end markers on stderr around tool execution. Begin after Ongoing persistence, end in finally path. --- chipcompiler/engine/flow.py | 5 ++ chipcompiler/runtime/log_stream.py | 18 ++++-- chipcompiler/runtime/worker.py | 72 +++++++++++++++------- test/runtime/test_log_stream.py | 25 ++++++++ test/runtime/test_worker.py | 99 ++++++++++++++++++++++++++++++ 5 files changed, 192 insertions(+), 27 deletions(-) diff --git a/chipcompiler/engine/flow.py b/chipcompiler/engine/flow.py index 1b59b6c6..192d78f2 100644 --- a/chipcompiler/engine/flow.py +++ b/chipcompiler/engine/flow.py @@ -480,6 +480,10 @@ def run_step( self.workspace.logger.info(f"[STEP] {step_tag} pid={os.getpid()} started") + from chipcompiler.runtime.log_stream import emit_step_marker + + emit_step_marker("begin", step=workspace_step.name, tool=workspace_step.tool) + pid = os.getpid() start_memory_mb = get_process_rss_mb(pid) peak_memory = [start_memory_mb] @@ -513,6 +517,7 @@ def run_step( delattr(self.workspace, "_runtime_flow_observer") else: self.workspace._runtime_flow_observer = previous_observer + emit_step_marker("end", step=workspace_step.name, tool=workspace_step.tool) # compute metrics peak_memory_mb = peak_memory[0] - start_memory_mb diff --git a/chipcompiler/runtime/log_stream.py b/chipcompiler/runtime/log_stream.py index 34c61d68..92baeb63 100644 --- a/chipcompiler/runtime/log_stream.py +++ b/chipcompiler/runtime/log_stream.py @@ -13,6 +13,7 @@ import os import threading from collections.abc import Callable +from contextlib import suppress from dataclasses import dataclass, field from pathlib import Path from typing import BinaryIO @@ -144,11 +145,13 @@ def _process_buffer(self, buf: bytes) -> bytes: def _handle_marker(self, marker: StepMarker, raw_line: bytes) -> None: if marker.event == "begin": - self._close_archive() - self._state.active_step = marker.step - self._state.active_tool = marker.tool - self._state.steps_seen.append(marker.step) - self._open_archive(marker.step, marker.tool) + if self._state.active_step is None: + self._state.active_step = marker.step + self._state.active_tool = marker.tool + self._state.steps_seen.append(marker.step) + self._open_archive(marker.step, marker.tool) + else: + self._emit_data(raw_line) elif marker.event == "end": if marker.step == self._state.active_step and marker.tool == self._state.active_tool: self._close_archive() @@ -165,7 +168,10 @@ def _emit_data(self, data: bytes) -> None: self._state.archive_file.write(data) self._state.bytes_archived += len(data) except OSError as exc: - self._state.error = exc + if self._state.error is None: + self._state.error = exc + with suppress(OSError): + self._state.archive_file.close() self._state.archive_file = None self._update_tail(data) if self._on_output is not None: diff --git a/chipcompiler/runtime/worker.py b/chipcompiler/runtime/worker.py index 5f39db95..71e8feb9 100644 --- a/chipcompiler/runtime/worker.py +++ b/chipcompiler/runtime/worker.py @@ -85,7 +85,7 @@ def read_response(self, request_id: int = 1) -> dict: Checks the pending-response buffer first (for out-of-order delivery).

worker lifecycle in RunOperation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the fake one-RPC wrapper with the canonical session sequence: rpc.hello → workspace.open → flow.run → rpc.shutdown → EOF wait. Key changes: - Default argv now launches `ecc rpc serve --stdio --persistent-db` - Graceful shutdown via rpc.shutdown RPC, not signals - Archive completion is a required condition for success (archive error, reader timeout, or unmatched begin marker all force failure) - Protocol failures (dead worker, invalid envelope, EOF) route through crash recovery with flow.json repair - Non-object JSON marker payloads no longer crash parse_marker - LogStreamReader gains a `completed` property for checked drain Tests rewritten to exercise the full multi-request lifecycle with hello/open/run/shutdown, plus crash repair, protocol failure recovery, archive error detection, and non-object marker resilience. --- chipcompiler/runtime/log_stream.py | 9 + chipcompiler/runtime/worker_operation.py | 162 +++++++++---- test/runtime/test_worker_operation.py | 277 +++++++++++++++-------- 3 files changed, 311 insertions(+), 137 deletions(-) diff --git a/chipcompiler/runtime/log_stream.py b/chipcompiler/runtime/log_stream.py index 1d94e178..ce531439 100644 --- a/chipcompiler/runtime/log_stream.py +++ b/chipcompiler/runtime/log_stream.py @@ -50,6 +50,8 @@ def parse_marker(line: bytes) -> StepMarker | None: data = json.loads(payload) except (json.JSONDecodeError, UnicodeDecodeError): return None + if not isinstance(data, dict): + return None event = data.get("event") step = data.get("step") tool = data.get("tool") @@ -107,6 +109,13 @@ def join(self, timeout: float | None = None) -> None: if self._thread is not None: self._thread.join(timeout=timeout) + @property + def completed(self) -> bool: + """True if the drain thread has finished (or was never started).""" + if self._thread is None: + return True + return not self._thread.is_alive() + def stop(self) -> None: self._stop.set() diff --git a/chipcompiler/runtime/worker_operation.py b/chipcompiler/runtime/worker_operation.py index 4d827591..5c9e526a 100644 --- a/chipcompiler/runtime/worker_operation.py +++ b/chipcompiler/runtime/worker_operation.py @@ -5,6 +5,8 @@ execution from CLI entry points should go through RunOperation.

direct-execution fallback MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Wire a canonical workspace step-log resolver into the production worker route so that RunOperation archives EDA output to the correct step log paths (/_/log/.log). Remove the binary-missing fallback to engine_flow.run_steps() — a missing worker binary now returns a structured OperationResult with error detail instead of silently falling back to in-process execution.

Markers with (step, tool) pairs not in the set are treated as ordinary stderr data, preventing untrusted marker strings from switching archive ownership. After resolving a path, enforce that it resolves under workspace_dir before opening the archive file. This prevents path traversal via crafted marker step names like "../../escape". Resolver and on_output callback exceptions are now isolated: first error is recorded, the failed sink is disabled, and draining continues to EOF so pipe backpressure cannot deadlock the worker. The production CLI route reads flow.json to build the allowlist before starting RunOperation. --- chipcompiler/cli/command_handlers/project.py | 15 ++ chipcompiler/runtime/log_stream.py | 44 ++++- chipcompiler/runtime/worker_operation.py | 4 + test/runtime/test_log_stream.py | 177 +++++++++++++++++++ 4 files changed, 237 insertions(+), 3 deletions(-) diff --git a/chipcompiler/cli/command_handlers/project.py b/chipcompiler/cli/command_handlers/project.py index 3aefd1e2..dbe0507b 100644 --- a/chipcompiler/cli/command_handlers/project.py +++ b/chipcompiler/cli/command_handlers/project.py @@ -204,6 +204,7 @@ def _run_flow_via_worker(workspace_dir: str): Returns an OperationResult.

It writes +bytes to fd 1/2 and emits step markers on fd 2. Workspace state files +(flow.json, home.json) and the workspace logger (`log/.log`) are +exempt from this rule; it applies to step tool logs only. + +Each client (CLI, GUI) archives the byte stream into per-step log files as a +client-side result. Files are archival results: any tool that later reads a +step log (GUI history view, `ecc log`, failure-context extraction) is a +read-only consumer and does not care which client wrote it. + +Markers are private to the byte-stream layer.

fa1db8c8c6f4829f1b5bf55c4e857a5649a38a6d Mon Sep 17 00:00:00 2001 From: Emin Date: Tue, 18 Aug 2026 17:38:36 +0800 Subject: [PATCH 17/52] feat(cli): route every ecc run variant through the worker All execution paths now go through RunOperation; the TTY distinction only selects UI rendering. - run --workspace maps --resume/--from onto flow.run_step with reset_dependents plus a follow-up flow.run in one worker session, and --only/--force onto a single flow.run_step; the no-op cases (already successful selections) keep their current records. - run_flow_with_progress is rewritten around the reader callbacks: begin markers drive step transitions, on_output drives the throttled live line, and per-step final states refresh from flow.json on each begin marker and once at operation end. - LogStreamReader gains an on_step_event callback fired on matched begin/end markers; RunOperation forwards it. - Delete preserve_cli_stdio, the log monitor, the incremental log tail, redirect_stdio_to_file, and the in-process rerun execution. --- chipcompiler/cli/command_handlers/project.py | 203 +++- chipcompiler/cli/rendering/progress.py | 388 ++----

Date: Tue, 18 Aug 2026 18:07:42 +0800 Subject: [PATCH 19/52] fix(runtime,cli): drain C stdio before markers and harden archive target checks Review follow-ups for the worker-streamed logs delta: - emit_step_marker now drains C/C++ stdio buffers (flush_cstdio) before writing, so native output can never land on the wrong side of a step boundary. - parse_marker rejects JSON boolean versions (true == 1 in Python). - LogStreamReader validates step/tool names (no separators, dot segments, or empty values) and containment before activating a step; violating begin frames degrade to ordinary bytes instead of being consumed. - ecc run --workspace --only maps executed steps to flow.run_step with rerun: true, restoring the previous clean-artifact contract; --force remains the gate for re-executing a successful step. - Add CLI-level tests that execute against a real worker subprocess: --resume suffix execution with archiving, --only single-step execution, and non-TTY flow.run archival with no marker leakage. --- chipcompiler/cli/command_handlers/project.py | 4 +- chipcompiler/runtime/log_stream.py | 64 +++++- test/cli/commands/test_run.py | 2 +- test/cli/commands/test_run_worker.py | 230

8fee40bd11e7acbff26105abd220a4b88e0dc2a9 Mon Sep 17 00:00:00 2001 From: Emin Date: Tue, 18 Aug 2026 18:24:45 +0800 Subject: [PATCH 20/52] feat(runtime): add invalidate_dependents for faithful --only reruns The documented workspace-mode contract requires a re-executed step to replace its own artifacts and mark downstream steps Unstart while keeping their outputs. reset_dependents cannot express this because it also clears downstream artifacts, so FlowRunStepRequest gains an additive invalidate_dependents field: the server prepares only the target step and marks the downstream suffix Unstart in flow.json. Also resolve the remaining review findings: the log reader now resolves and validates an archive target exactly once and opens that validated path, and the C stdio ordering test uses an explicitly buffered FILE* so it fails without the flush. --- chipcompiler/cli/command_handlers/project.py | 3 +- chipcompiler/runtime/log_stream.py | 56 +++++---------- chipcompiler/runtime/requests.py | 5 +- chipcompiler/runtime/workspace_api.py | 26 ++++++- test/cli/commands/test_run.py | 8 ++- test/cli/commands/test_run_worker.py | 72 +++++++++++++++++++- test/runtime/test_log_stream.py | 15 +++- test/runtime/test_requests.py | 19 +++++- test/runtime/test_workspace_api.py | 57 ++++++++++++++++ 9 files changed, 209 insertions(+), 52 deletions(-) diff --git a/chipcompiler/cli/command_handlers/project.py b/chipcompiler/cli/command_handlers/project.py index 85b8dd13..128ce66d 100644 --- a/chipcompiler/cli/command_handlers/project.py +++ b/chipcompiler/cli/command_handlers/project.py @@ -612,7 +612,8 @@ def no_op_result() -> CommandResult: if command_input.only is not None: # An executed --only step always reruns with clean artifacts; the # --force distinction only gates whether a successful step qualifies. - calls = [("flow.run_step", {"step": target, "rerun": True})] + # Downstream steps keep their outputs but are marked Unstart. + calls = [("flow.run_step", {"step": target, "rerun": True, "invalidate_dependents": True})] else: calls = [ ("flow.run_step", {"step": target, "rerun": True, "reset_dependents": True}), diff --git a/chipcompiler/runtime/log_stream.py b/chipcompiler/runtime/log_stream.py index c9e4d42b..86368e77 100644 --- a/chipcompiler/runtime/log_stream.py +++ b/chipcompiler/runtime/log_stream.py @@ -188,27 +188,28 @@ def _is_allowed_step(self, step: str, tool: str) -> bool: return True return (step, tool) in self._valid_steps - def _archive_target_ok(self, step: str, tool: str) -> bool: - """Validate sanitization and containment before activating a step. + def _validated_archive_path(self, step: str, tool: str) -> Path | None: + """Resolve and validate the archive path for a begin marker. - A marker whose archive target is unsafe or unresolvable is degraded to - ordinary bytes instead of activating archival. + Returns the validated path, or None when archiving is not configured + (resolver absent) or when the marker must degrade to ordinary bytes + (unsafe names, resolver failure, containment violation).

2026 08:44:31 +0800 Subject: [PATCH 26/52] fix(runtime,engine): close the post-processing trust gaps - run_step no longer emits the end marker when the final state could not be persisted; the step downgrades to Imcomplete so consumers see a crashed step rather than a stale flow.json claiming success. - repair_flow_state now also repairs a Success record for the step that was active at crash time: a Success without a completed end marker means the crash interrupted post-processing, so the persisted result is not trustworthy. - Rerun invalidation is atomic again: the invalidation is persisted before any artifact directory is deleted, and a failed save refuses to modify outputs (matching the previous CLI contract). - The worker's flow build verifies tool dependencies only for steps that will actually execute, so resume/from/only runs reuse successful predecessor outputs when an unselected tool is absent. - The 512-byte marker holdback is now inclusive per the specification; exactly-512-byte incomplete candidates are held and consumed. --- chipcompiler/engine/flow.py | 19 ++++++- chipcompiler/runtime/log_stream.py | 2 +- chipcompiler/runtime/worker.py | 9

EngineFlow.run_step now invokes the tool through _invoke_step_tool and derives the state through _derive_step_state; the base hooks preserve existing behavior exactly.
