📝 WalkthroughWalkthroughThis change replaces Dagger workflows with devenv and repodoc. It adds multi-store throughput benchmarks, worker profiling, and PostgreSQL timing instrumentation. It also updates CI, documentation, compatibility tasks, dependency constraints, and analyzer exclusions. ChangesRepository modernization
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🔴 Critical · up to The PR introduces centralized benchmark and CI behavior plus PostgreSQL connection and timing changes, but the current head still has a compile blocker and concrete failures that can prevent services from starting, bypass configured consumer isolation, leak resources, or suppress benchmark reports. These issues should be fixed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

Inline comments:
In @.github/workflows/aggregate.yaml:
- Around line 43-45: Pin all referenced GitHub Actions to full immutable commit
SHAs while retaining their release versions in comments: update
actions/checkout, cachix/install-nix-action, and cachix/cachix-action in
.github/workflows/aggregate.yaml lines 43-45; make the same changes in
.github/workflows/benchmarks.yaml lines 38-40; and pin actions/upload-artifact
in .github/workflows/benchmarks.yaml line 114.
- Line 51: Update the benchmark workflow by adding devenv processes wait after
devenv up -d in .github/workflows/benchmarks.yaml lines 45-46 and before the
external-store benchmark commands, so services are ready before connections;
update the aggregate workflow command at .github/workflows/aggregate.yaml line
51 only as needed to preserve this ordering, with no direct change required
there if the root fix is confined to benchmarks.yaml.
In `@benchmark/benchmark_display.dart`:
- Around line 1-3: Add artisanal to the root package dependencies in
pubspec.yaml so the import used by benchmark_display.dart and invoked through
profile_job.dart resolves successfully.
In `@benchmark/stem_job_profile.dart`:
- Around line 284-286: Convert the clamped percentile index to int before
indexing the sorted list. Update _percentile in benchmark/stem_job_profile.dart
at lines 284-286 and the corresponding percentile logic in tool/profile_job.dart
at lines 186-188; both sites require the same change using toInt().
In `@packages/stem_postgres/lib/src/brokers/postgres_broker.dart`:
- Around line 83-121: Change the separateConsumerConnection default in
PostgresBroker.connect to false to preserve the existing single-connection
behavior for callers, while allowing benchmarks or explicit callers to opt in to
a separate consumer connection. Update connect’s documentation to describe the
concurrency difference from fromDataSource, which does not create a consumer
connection.
- Around line 262-287: Update _notifyTiming to accept a resolved component value
instead of hardcoding 'broker', and pass isolatedConsumer ? 'broker.consumer' :
'broker' from each _notifyTiming call in _withDb so timing events match the
connection source.
In `@packages/stem_postgres/lib/src/connection.dart`:
- Around line 121-144: Ensure the reopen-and-retry paths record failed retries
before propagating errors: in packages/stem_postgres/lib/src/connection.dart
lines 121-144, wrap the retried connection.transaction call in its own try/catch
and call _notifyTiming with succeeded: false and the retry error before
rethrowing; apply the same change to the retried action() call in
packages/stem_postgres/lib/src/brokers/postgres_broker.dart lines 226-240.
In
`@packages/stem_postgres/test/integration/brokers/postgres_broker_integration_test.dart`:
- Around line 29-51: Update the integration test around PostgresBroker.connect
to observe queryTimingListener component names and assert the default
independent-connection path emits both “broker” and “broker.consumer”. Add a
companion case using separateConsumerConnection: false that verifies only
“broker” is emitted, while preserving the existing publish/consume coverage.
In `@README.md`:
- Around line 290-305: Update the Dart version requirement documentation in the
README and the root repodoc README to state a minimum supported Dart version of
3.10.0+, replacing any outdated 3.9.2 requirement while keeping the documented
devenv version unchanged.
In `@repodoc/lib/src/benchmarks/postgres_timing.dart`:
- Around line 5-17: Update the timing aggregation around _byOperation, _byQuery,
add, and addQuery to replace unbounded per-event retention with per-key running
count, sum, maximum, and failure totals, while retaining only a fixed-size
bounded sample of timings for p95 calculation. Preserve operation/query key
grouping and ensure SQL strings are not retained once they fall outside the
bounded sample.
In `@repodoc/lib/src/benchmarks/throughput_display.dart`:
- Around line 119-131: Update the query-table section title in the relevant
display-building method to indicate truncation when queryRows.length exceeds 20,
including the total queryRows count next to the title; keep the existing title
unchanged when 20 or fewer rows are present and preserve the queryRows.take(20)
limit.
- Around line 139-148: Extract the identical _number and _fixed helpers into one
shared formatting module, then import and reuse them in
repodoc/lib/src/benchmarks/throughput_display.dart#L139-L148. Delete the
duplicate local helpers from benchmark/benchmark_display.dart#L126-L135 and
import the same shared module there, preserving the existing thresholds and
decimal formatting.
- Around line 102-106: Guard the postgres_queries access in the queryRows
construction before force-unwrapping or casting it to List. Skip results where
postgres_queries is absent or not a list, while preserving the existing query
map filtering and concurrency field for valid results.
In `@repodoc/lib/src/benchmarks/throughput_store.dart`:
- Around line 93-123: In the SqliteResultBackend.open failure handler, after
closing the broker, delete the temporary database file when sqlitePath is null;
preserve caller-provided database files and rethrow the original error.
- Around line 176-183: Update the PostgreSQL failure handler around the resource
close calls to use nested try/finally cleanup, matching
ThroughputStoreResources.close, so every resource is attempted in order even if
an earlier close throws and the original failure is rethrown after cleanup.
In `@repodoc/lib/src/benchmarks/throughput.dart`:
- Around line 191-194: Update _rate so zero-duration measurements return a
JSON-safe finite value, such as 0, instead of double.infinity; preserve the
existing count-per-second calculation for nonzero durations.
- Around line 66-84: Update the completion checks in the _ThroughputTask
onComplete callback to use greater-than-or-equal comparisons for both
warmupCompletedTasks and completedTasks, so duplicate or redelivered completions
still complete warmupCompleted and completed once their expected thresholds are
reached.
In `@repodoc/lib/src/commands/benchmark_throughput_command.dart`:
- Around line 220-235: Update _baselineMinimum to construct the benchmark
baseline path with the platform-aware path utility, such as path.join, using
root.path and the repository subpath components. Preserve the existing existence
check, JSON parsing, and validation behavior.
In `@repodoc/lib/src/commands/coverage_command.dart`:
- Around line 100-114: Resolve both unreachable paths in CoverageRunner: either
include packages/stem_memory in packagePaths so its zero minimum-coverage
handling is exercised, or remove that special case while preserving the intended
Taskfile behavior; also remove or reposition the coverageDirectory check so it
occurs before format_coverage runs, allowing the missing-directory condition to
be handled.
In `@repodoc/lib/src/commands/demo_commands.dart`:
- Around line 90-97: Update DirectoryPackage.directory to construct the path
with package:path’s p.join using root.path and relativePath, replacing the
hardcoded slash join while preserving the getter’s returned Directory.
In `@repodoc/lib/src/commands/test_commands.dart`:
- Around line 332-352: The Flutter toolchain lookup is duplicated and uncached
across commands. In repodoc/lib/src/commands/test_commands.dart:332-352, move
_flutterExecutable, _pubTool, and _flutterRoot into new shared
infrastructure/toolchain.dart logic and cache the executable lookup while
preserving the resolved-path behavior. In
repodoc/lib/src/commands/deps_command.dart:42-47 and
repodoc/lib/src/commands/standalone_command.dart:90-95, remove each local
_pubTool and use the shared helper.
- Around line 254-268: Update the packageEnvironment initialization in the test
command loop so that when stemCliMulti is true for the stem_cli package, it
creates a mutable environment map even if the caller provided null, then sets
STEM_CLI_RUN_MULTI to true. Preserve the existing environment copy and null
behavior for all other packages and modes.
- Around line 189-196: Update the dashboard lookup in the dependency-resolution
flow around resolveDependencies so a missing packages/dashboard is handled as
optional, matching DepsCommand, while retaining the existing pub get execution
when the package is present.
In `@repodoc/lib/src/commands/workspace_command.dart`:
- Around line 27-50: Update the JSON output path and _jsonPackage to build a
list of package maps and encode the complete list with jsonEncode from
dart:convert, ensuring all string fields are safely serialized; remove the
manual _escape helper and hand-built JSON strings.
In `@repodoc/test/postgres_timing_test.dart`:
- Line 4: Replace the relative import in postgres_timing_test.dart with the
package:repodoc/src/benchmarks/postgres_timing.dart import, matching the package
import convention used by throughput_store_test.dart.
In `@repodoc/test/throughput_store_test.dart`:
- Around line 5-14: Extend the tests for ThroughputStore.parse to assert the
plain “postgres” literal maps to ThroughputStore.postgres, and add coverage
confirming surrounding whitespace is trimmed and uppercase or mixed-case input
is normalized to the correct store value. Keep the existing alias and
unknown-store assertions unchanged.

71-80: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick winRun diagnostic benchmarks after a memory baseline failure.
If the AOT memory gate at Lines 61-70 fails, GitHub Actions skips this JIT step and the external-store step at Line 80. The job then uploads no JIT, SQLite, PostgreSQL, or Redis results for the failed regression run.
Run the diagnostic steps on prior failure, while preserving the final job failure from the memory baseline gate. This keeps the hard gate and produces the required comparison artifacts.
