ci: run python SDK agent e2e against a SQLite server built from source

[ling-senpeng13]

What

Adds a gating python-sdk-e2e job to CI that boots the conductor server built from this commit in SQLite mode (the default persistence — no external DB) and runs the python SDK agent e2e suite against it, so a server change can't break the SDK end-to-end before a release.

How

• From-source server, SQLite: builds :conductor-server:bootJar and boots it on :8080. SQLite is the default (conductor.db.type=sqlite / queue.type=sqlite / indexing.type=sqlite), so no Postgres/Redis/ES services are needed.
• openai auto-config: the server reads conductor.ai.openai.api-key=${OPENAI_API_KEY:}, so setting the env var is enough — no manual integration registration.
• The suite runs in place from the SDK repo. conductor-oss/python-sdk is checked out at the pinned ref into .github/agent-e2e/src-python, and .github/agent-e2e/run-suite.sh runs its e2e/ against that repo's own build files — the same entrypoint python-sdk's own agent-e2e.yml uses. No dependency set is restated on our side, so an upstream dep change or version bump can't leave us testing something stale; if upstream breaks its own entrypoint, its CI goes red before ours does. Mirrors orkes-io/orkes-conductor#3888.
• The SDK is built from source, not resolved from PyPI. Nothing has to be published for a ref to work, so the pin can be any tag, branch or SHA — set the CONDUCTOR_PYTHON_E2E_BUNDLE_VERSION repo/org variable to point the lane at unreleased SDK work without a commit here. (The _BUNDLE_ in the name is vestigial; it matches the variable already configured in settings.) This lane tests the SDK at that ref rather than its packaged artifact — packaging is the SDK repo's own release CI to cover.
• Scheduler wired up: SCHEDULER_CONDUCTOR_URL points at the same server. Suite21 skips itself unless GET {url}/scheduler/schedules answers 200, and its default is port 8089; conductor-oss serves the scheduler itself (conductor.scheduler.enabled=true, SchedulerResource at /api/scheduler).
• Cost control: runs on push/dispatch/schedule, and on PRs only when agent-relevant paths change (ai/, agentspan/, server/, core/, sqlite-persistence/, .github/agent-e2e/, the workflow) via a detect-changes agent filter.
• Fork PRs are skipped. GitHub withholds secrets from fork-originated runs, so OPENAI_API_KEY would be empty and the LLM suites would fail for a reason an outside contributor cannot fix. The fork test is nested inside the pull_request branch of the if — as a top-level AND it would also disable push/dispatch/schedule, where github.event.pull_request is null.
• Passed-count floor. A pytest skip is not a failure, so a server change that breaks a test's setup silently converts pass → skip and the lane stays green while covering less. After the run, results/junit-e2e.xml is parsed and the job fails if fewer than E2E_MIN_PASSED (135) tests passed, or if the file is absent. -rs is passed to pytest so every skip reason appears in the log.
• Known failures are xfail-ed via .github/agent-e2e/known_failures_plugin.py, loaded as a trailing -p known_failures_plugin arg so the upstream suite is never modified. It reads known-failures-python.json, reports each entry's match count, and warns when an entry matches 0 or >1 tests so a stale or over-broad key is visible rather than silent.
• mcp-testkit is pinned to 1.0.3 with mcp<2: it declares mcp[cli]>=1.0.0 unbounded, and mcp 2.0.0 dropped mcp.server.fastmcp which the testkit imports at start-up — unpinned, the testkit exits immediately and every MCP suite skips. Same pin as fix(test): pin mcp<2 and gate mcp-testkit readiness #1408, which fixed the equivalent install in the test-harness.

Test results

145 collected → 135 passed, 7 skipped, 3 xfailed, 0 failed (~2m30s).

10 of 145 tests do not assert anything. Full breakdown:

xfail (3)

Test	Reason
test_suite14 :: test_stateful_swarm_handoff_completes	Stateful swarm times out. A tool worker on a swarm member registers with domain=None while the stateful swarm makes the server domain-route its task, so nothing polls it (pollCount=0) and the FORK's JOIN never satisfies. Fixed by conductor-oss/python-sdk#459 (unmerged). Listed run: false — it costs ~5min per attempt, ~15min with reruns.
test_suite21 :: test_get_after_delete_returns_none	get_schedule() on a deleted schedule is expected to return None; the server 404s and OrkesSchedulerClient propagates ApiException(404). Server/SDK contract mismatch.
test_suite7 :: test_image_openai	Carries its own @pytest.mark.xfail upstream — not listed by us.

skipped (7)

Count	Reason	Fixable here?
2	server secret store is read-only (env-backed)	No — conductor-oss serves secrets from the server process env
1	jupyter_client not installed	Yes, not yet wired
1	GOOGLE_AI_API_KEY not set	Needs a key
1	DG skill not installed	Local-developer path, N/A on CI
1	Server does not attach media to the Anthropic provider request	Server gap
1	Could not extract PDF URL from task output	Worth a look — reads like a real breakage wearing a skip

⚠️ Requires a repo secret

The job needs OPENAI_API_KEY (and optionally ANTHROPIC_API_KEY) as a repository/organization secret. The keys are deliberately not read from vars — GitHub variables are unmasked in logs and exposed to fork PRs, which would undermine the fork guard above.

Known limitation

run-suite.sh pip-installs at run time from the SDK's own package metadata, which bounds only its direct deps — pytest, langgraph and the provider SDKs all float. An upstream release can therefore redden this lane with no change to this repo, and it will present as a server regression. If the lane fails for no apparent reason, check the pip install output before hunting a server cause. Pinning the transitive set via PIP_CONSTRAINT works but needs the lockfile regenerated on every SDK bump — judged not worth the upkeep.

[ling-senpeng13]

Validated green ✅ (and the gate already earned its keep)

Ran on an internal branch so the org OPENAI_API_KEY / ANTHROPIC_API_KEY secrets are available (fork PRs can't see them — that's why the earlier fork draft #1350 was superseded by this one).

Final result: python-sdk-e2e job success — 0 failures / 154 tests / 26 skipped against a from-source server booted in SQLite mode (conductor-ai-e2e-python-2.0.0-rc2 bundle, real openai/gpt-4o-mini).

The gate surfaced a real server gap

While bringing this up, the job caught a genuine discrepancy (not infra):

agentspan skill register → POST /api/skills/register returns HTTP 404 "No static resource api/skills/register" on the server built from main.

That endpoint exists in the released 3.32.0-rc.8 (which conductor-oss/python-sdk's own agent-e2e.yml pins, so it's green there) but is absent from a from-source main build. Three Suite16 cli-skills tests hit it:

• test_cli_skill_register_list_get_pull_and_delete
• test_registered_cross_skill_dependency_versions_are_pinned
• test_cli_skill_run_registered_executes_downloaded_script_worker

They're xfail-ed (with the reason above) in .github/agent-e2e/known-failures-python.json so the lane gates green today. Worth a maintainer's look: either the skills-register endpoint needs to land on main, or it's expected to be absent and stays skip-listed. When it lands, those tests XPASS — the signal to delete the entries.

The other 151 tests — LLM chat/complete, tools, MCP, guardrails, termination, and the credential-lifecycle suites — all pass.

How the skip support works (kept even though ~green)

• .github/agent-e2e/known_failures_plugin.py — external pytest plugin (-p known_failures_plugin) that xfails any node-id listed in E2E_KNOWN_FAILURES. Tests still run; a fixed bug XPASSes (cleanup signal); a stale/mismatched entry is a harmless no-op that can't hide a regression.
• .github/agent-e2e/known-failures-python.json — the conductor-oss list (the 3 above).

Cost control

Runs on push/dispatch and on PRs only when agent-relevant paths change (ai/, conductor-agentspan/, server/, core/, sqlite-persistence/, the workflow) via the detect-changes agent filter — unrelated PRs don't spend LLM budget.

[ling-senpeng13]

Correction on the cli-skills failures — root cause + design decision

My earlier note said the skills-register endpoint was "missing on main." That was wrong — SkillController exists; it's gated:

@ConditionalOnProperty(name = {"agentspan.embedded", "agentspan.skills.enabled"}, havingValue = "true")

agentspan.embedded currently resolves true in OSS (via conductor.integrations.ai.enabled=true), but agentspan.skills.enabled is unset, so POST /api/skills/register → 404.

Design decision (per maintainers): agentspan.embedded is intended to be true only for orkes-conductor and false for conductor-oss, and that design may change. So we will not force-enable skills on boot for OSS — the skills API isn't a settled OSS surface. The 3 Suite16 cli-skills tests stay xfail-ed with an accurate reason, tracked in #1353; they'll XPASS (and the entries get removed) once the OSS skills story is settled.

Everything else is unchanged: 0 real failures / 154 tests, gate green.

Blocking

1. Fork PRs are unhandled. Public repo, and GitHub doesn't pass secrets to forks → OPENAI_API_KEY is empty, but the job runs anyway. Every outside contributor who touches core/** gets either a red X they can't fix, or a green check that tested nothing. Fix:

if: >-
  (github.event_name != 'pull_request' ||
   needs.detect-changes.outputs.agent == 'true') &&
  github.event.pull_request.head.repo.full_name == github.repository

2. Tests that quietly stop running don't turn the gate red. A pytest test ends in one of three ways: pass (checked something, it worked), fail (checked something, it broke), or skip — checked nothing at all. This suite's tests skip themselves whenever they can't set up (missing binary, missing API key, endpoint that doesn't answer). CI only goes red on fail, so skips are free. The green run was 154 tests: 127 checked something, 27 checked nothing, ✅ with no mention of it.

The danger: a server change that removes something a test needs in its setup makes that test skip rather than fail — coverage silently drops to zero and the gate stays green. The lane built to catch the break becomes the thing hiding it. Both flags on the report step (fail_on_failure: false, require_tests: false) mean there's no backstop either; even an empty results file renders green.

Fix: after the run step, parse results/junit-e2e.xml and fail if the passed count drops below a floor (127 today, bumped deliberately). Add -rs to the pytest args so skip reasons show up in the log.

3. Finding #2 has already bitten this PR. Commit 8ca8ffe added the agentspan CLI download specifically so the credential suites would run. They still skip — suite2/3/4/5 @credentials and both suite26 tests, plus all 10 of test_suite21_scheduling.py. CI was green, the PR body lists them as passing, and nobody noticed. Either wire them up or correct the claims; the CLI download step may be dead weight as written.

4. _matches() can silently xfail unrelated tests. known_failures_plugin.py:58 — the unanchored nid.endswith(suf) arm means a key like _completes matches every test whose name ends that way, which is exactly the "silently hide a regression" case the docstring says can't happen. Drop that arm; keep the exact and ::-anchored matches.

5. The plugin's only diagnostic never prints. [known-failures] xfail-marked N item(s) is absent from the run log: under xdist, collection happens in workers, where terminalreporter is None. So there's no visibility into whether entries matched — and combined with #4, a typo'd key and an over-broad key are equally invisible. Log per-key match counts and warn on zero.

[mp-orkes]

I've left some feedback - please address it before requesting another review.

[ling-senpeng13]

Thanks — all five addressed. Commit per item below. Two of them I implemented differently from the suggested fix, and I've said why rather than quietly diverging.

---

1. Fork PRs are unhandled — b5f91207f

Agreed and fixed. I did change the condition, because the suggested form also disables the lane on push, workflow_dispatch and schedule: on those events github.event.pull_request is null, so .head.repo.full_name == github.repository is false, and a top-level AND fails the whole expression. Nesting the fork test inside the pull_request branch keeps the intent without taking out the lane's main coverage:

if: >-
  github.event_name != 'pull_request' ||
  (needs.detect-changes.outputs.agent == 'true' &&
   github.event.pull_request.head.repo.full_name == github.repository)

Scenario	suggested	applied
push / dispatch / schedule	❌ skipped	✅ runs
PR same-repo, agent paths	✅ runs	✅ runs
PR from fork	❌ skipped	❌ skipped

On the two outcomes named: the realistic one is the red X. The server boots fine without a provider key (it just logs cannot init ...AIConfiguration), and nothing in conftest.py skips on "no model available" — it only skips on "server unreachable" — so the suites fail rather than false-green.

2. Skips don't turn the gate red — b89ba0e10, floor raised in 7b1b23687

Implemented as described: -rs added, and a step after the run parses results/junit-e2e.xml and fails below a floor (also fails if the file is absent). Both flags you flagged on the report step are indeed no backstop — confirmed.

Floor is 137, not 127: item 3 recovered 10 tests. One subtlety worth recording — junit folds xfail into skipped, so passed has to be computed as tests - errors - failures - skipped. Verified against the real file and against CI, both giving passed=137.

3. Already bitten — 7b1b23687 (+ 2c41926a4 → reverted by 10d77edf2), PR body rewritten

Correct, and it split three ways:

Scheduling — wired up, +10 tests. Not a credential issue at all. Suite21 probes {SCHEDULER_CONDUCTOR_URL}/scheduler/schedules and defaults to port 8089; the lane's server is on 8080, so the probe never matched. conductor-oss serves the scheduler itself (conductor.scheduler.enabled=true by default, SchedulerResource at /api/scheduler) — verified 200 against the lane's own server. Pointing the var there: 10 pass, 1 fails for a real reason (get_schedule() on a deleted schedule 404s instead of returning None), now listed with that description rather than swept up. It's 11 tests in that file, not 10.

Credential suites — cannot be wired up here. They skip on server secret store is read-only (env-backed), a genuine conductor-oss limitation; suite26's own comment says so. Those 5 will not run on this flavor.

"CLI download may be dead weight" — tested, and it is not. I removed it on exactly that reasoning and the run turned 3 clean skips into hard failures in suites 2, 4 and 5. The credential suites reach their skip through the CLI: CredentialsCLI.set() shells out, the server rejects the write as read-only, and that stderr is what triggers pytest.skip. subprocess.run has no try/except there, so with no binary they raise FileNotFoundError. Reverted in 10d77edf2 and the reason is now recorded at the step so it doesn't get removed again.

PR body rewritten with a "Coverage, honestly" section: 154 collected → 137 passed, 11 skipped, 6 xfailed, every skip tabled with its reason and whether it's fixable here.

4. _matches() can silently xfail unrelated tests — f954b9e3c

Real bug, confirmed: _completes does match test_stateful_swarm_handoff_completes via the unanchored arm.

Dropping that arm would have broken the lane, though. Node-ids are e2e/<file>.py::<Class>::<test> while the list's keys are <file>.py::<Class>::<test>, so neither the exact nor the ::-anchored arm matches them — the unanchored arm is the only thing making today's 5 entries work. Removing it would have un-xfail-ed every known failure and turned the lane red.

Anchored on / instead, which is the same guarantee:

if nid == suf or nid.endswith("::" + suf) or nid.endswith("/" + suf):

Verified: each of the 5 entries matches exactly one node-id, no node-id matches two keys, and _completes / completes / returns_none / and_delete / e now match nothing (all previously leaked).

5. Diagnostic never prints — 10dbead16

Confirmed before fixing — zero occurrences of [known-failures] in either full CI-shaped run. (Careful if you re-test: it does print under --collect-only -n, because xdist collects on the controller there.)

Per-key match counts now reported over two channels, since neither alone reaches the log: warnings for the 0-match and >1-match cases (xdist forwards worker warnings to the controller), and terminal lines for the full table, written inline without xdist or from pytest_testnodedown with it. Counting is per key rather than per first-match, so an over-broad key stays visible even when another key claimed the item first.

[known-failures] xfail-marked 5 item(s) from .../known-failures-python.json
[known-failures]   1x  test_suite14_..._handoff_completes
[known-failures]   1x  test_suite16_..._register_list_get_pull_and_delete
[known-failures]   1x  test_suite16_..._run_registered_executes_downloaded_script_worker
[known-failures]   1x  test_suite16_..._cross_skill_dependency_versions_are_pinned
[known-failures]   1x  test_suite21_..._get_after_delete_returns_none

An injected bogus key reports 0x ... <-- MATCHED NOTHING plus a warning.

---

Also fixed from a self-review pass

• 44b8fc621 — stale plugin docstring ("empty when the suite is green" against a 5-entry list); a missing E2E_KNOWN_FAILURES path loading nothing and returning before any reporting, so every forgiven failure reported as real with no explanation; and the mcp-testkit readiness probe, which used curl -sf against a root path that returns 404 — it never succeeded, always burned all 15 iterations, and printed "started" whether or not anything was listening.
• 6935ea940 — setup-java v4 → v5 in this job, matching every other job.
• 137428dfd — reverted a transitive-dependency lockfile I'd added. It worked, but had to be regenerated on every bundle bump, and it's the wrong repo for it: the floating deps are declared in python-sdk (pyproject.toml + the bundle's generated requirements.txt), not here. Replaced with a comment recording the risk and, more usefully, that a mystery failure here should be triaged as a possible dependency bump before hunting a server cause.

Current state

137 passed, 11 skipped, 6 xfailed, 0 failed — matching locally and on CI.

Known-not-covered, all listed in the PR body: 5 credential tests (read-only secret store), 3 cli-skills (server-side skills API unsupported — agentspan.skills.enabled is off by default and set in exactly one place repo-wide), suite14's deterministic hang (#1363), and the scheduler 404/None mismatch. Two remaining skips are fixable and not yet wired (GITHUB_TOKEN, jupyter_client), and one — Could not extract PDF URL from task output — reads like a real breakage wearing a skip and deserves a look.
