The 50ms budget raced external-process spawn on cold CI runners: cancel
could fire before yes produced output, so the builtin tail flushed an
empty ring buffer (0 lines instead of 5, Linux x64 modern). 750ms keeps
the post-cancel drain scenario while outlasting spawn latency.
Default ChildProcess unconditionally pushed every raw stderr chunk into
`#stderrChunks`, so long-lived noisy subprocesses (LSP/DAP/RPC) grew OMP
memory linearly despite the 32 KiB visible tail cap.
- Allocate `#stderrChunks` only when full capture is requested at spawn.
- Decouple retention from stream exposure via `spawnInternal`, so
`exec({ stderr: "full" })` retains without an unused live tee.
- Reject retroactive `wait({ stderr: "full" })` on a default child with a
clear error instead of returning truncated data.
Fixes#5759
Kept live process logs isolated while globally retaining only the five newest files from completed processes.
Removed one-use audit files after their owning process exits and covered short-lived invocation cleanup.
Fixes#5716
Made fatal reporting bypass revoked stderr streams and armed a referenced forced-exit watchdog around bounded cleanup.
Separated rotating log and audit namespaces by PID and disabled compression pipelines so concurrent TUI processes cannot race shared rotation state.
Fixes#5716
Extended the OTLP export bootstrap beyond traces so omp emits the full
OpenTelemetry signal set from a single session.
- Registered a LoggerProvider + BatchLogRecordProcessor and a MeterProvider
+ PeriodicExportingMetricReader when their OTLP endpoints (or the shared
endpoint) are set, each gated independently by OTEL_*_EXPORTER=none,
OTEL_SDK_DISABLED, and http/protobuf protocol checks.
- Bridged the centralized logger through a new registerLogSink API so every
log event also becomes an OTLP log record with severity, attributes, and
active span context for log-trace correlation (min level via OTEL_LOG_LEVEL).
- Recorded gen_ai.client.token.usage and pi.omp.agent.* metrics from the
agent run summary and per-chat usage hooks, and emitted a structured run
summary log event.
- Added an out-of-process logs+metrics probe and gating tests covering the
per-signal kill switches.
Fixes#4604
Argument/flag validation failures in the minimal CLI framework threw a
plain Error that bubbled to the process-level catch in cli.ts, which
dumps a Bun.inspect code frame — a minified dist/cli.js excerpt in
compiled binaries. A missing model on `omp bench` looked like a crash.
- Add CliUsageError; throw it from Command.parse for missing/invalid
args and flags.
- Catch CliUsageError in run(): print `error: <msg>` plus the command
usage line to stderr, exit 1, no stack.
- Render required variadic positionals as MODELS... in usage, not the
misleading optional [MODELS]; extract commandUsageLine helper.
Fixes#5369
Rules whose condition led with a PCRE-style inline flag group (e.g.
`(?i)`) never registered: `new RegExp("(?i)...")` throws in Bun/JS, so
the condition failed to compile and `TtsrManager.addRule` dropped the
rule as having zero usable conditions.
- Add `compileRuleCondition` in capability/rule.ts translating a leading
`(?i)`/`(?m)`/`(?s)` group into native RegExp flags; wire it into the
TtsrManager and both ttsr-cli compile sites.
- Strip surrounding quotes from scope tokens so a malformed
`scope: "text","thinking"` recovers to canonical `text`/`thinking`.
- Reparse each value in parseFrontmatter's YAML fallback so one bad line
can't leave sibling values wrapped in literal quotes.
Fixes#4796
Registered ACP session disposal with postmortem and replaced the hard EOF exit with the awaited graceful shutdown path.
Classified stdio-write EPIPE separately from worker IPC EPIPE so ACP peer loss exits successfully after cleanup.
Fixes#4788
- Added bounded A* routing extents plus an expansion backstop so unreachable attachment points return null instead of searching the unbounded quadrant.
- Covered the reported declaration-order graph and an enclosed destination attachment point.
- Documented the Mermaid ASCII routing fix in the utils changelog.
Fixes#5293
- Relocated `AsyncDrain` class from `coding-agent` to `utils` package.
- Updated `HistoryStorage` to import `AsyncDrain` from shared utilities.
- Centralized the utility to allow reuse across the codebase.
On a fresh profile ~/.omp/logs may not exist yet (the logger creates it
lazily), so opening getLogPath() with "a" threw and the guard fell back to
/dev/null — discarding macOS diagnostics and native crash reports instead
of preserving them in the omp log. mkdir the redirect target's parent
(recursive) before opening; the /dev/null fallback stays as the safety net.
On macOS, libmalloc writes runtime diagnostics (e.g. "MallocStackLogging:
can't turn off malloc stack logging because it was not enabled") directly
to fd 2 of the running TUI process at arbitrary times, painting into the
viewport. The existing env-strip only protects child processes.
Add a fd-level stderr guard in pi-utils (suppressTerminalStderr /
restoreTerminalStderr) that dup2-redirects fd 2 to the omp log file while
the TUI owns the terminal, and restores it at every ownership handoff
(external editor, Ctrl+Z suspend, shutdown, crash restore). Postmortem
fatal handlers restore fd 2 before printing so crash reports stay visible.
Mirrors openai/codex#24459.
