Cover the pm-github failure surface against a local HTTP GitHub server - #24
Conversation
pm-github is what the ecosystem relies on for two-way GitHub issue sync, so its correctness determines whether each repo's pm items can be trusted as the source of truth. The gate accepts 76/78/75 only because the threshold was pinned to that measured floor, leaving roughly a quarter of a 4332-line sync engine unexercised -- and the uncovered part is the failure surface, which for a sync tool is where the damage lives. pm-github-n3z3 cover the failure and edge surface, ratchet the floor
pm-github is what the ecosystem relies on for two-way GitHub issue sync, so its
correctness decides whether each repo's pm items can be trusted as the source of
truth. The gate accepted 76 lines / 78 branches / 75 functions because the
threshold was pinned to that measured floor, and the uncovered quarter of a
4332-line engine was its failure surface — which for a sync tool is exactly
where the damage lives.
The tests drive the real HTTP stack against a local `http.createServer` on an
ephemeral port rather than stubbing the functions under test, so request
building, response decoding, retry, backoff, redirect and pagination all
actually run. What is now covered:
- 429 with Retry-After, 5xx transient, and 403 primary rate limit (remaining=0)
each retried and then succeeding; a persistent 429 giving up at maxRetries
- 404 and 422 as non-retryable, throwing immediately with no retry
- a same-origin redirect forwarding the token, and a cross-origin redirect
DROPPING it, so a credential leak through Location is a test failure
- redirect loops rejected instead of spinning
- a transport error (connection refused) surfacing as a rejection
- Link-header pagination with no silent truncation, plus empty and single page
- a malformed JSON body
- mid-batch 422 during export continuing to partial success, and a non-empty
batch that writes nothing exiting non-zero
- a 404 reading upstream sync state being skipped rather than aborting the run
- the search provider degrading to no hits when GitHub is unreachable
Reaching that required two production changes, both deliberately minimal:
`githubApiBase()` reads a `PM_GITHUB_API_BASE` override at CALL time rather than
module-eval time, so a test can retarget per case without import-order coupling
and production is byte-identical when the variable is unset. `requestOnce` now
dispatches on the URL scheme instead of hard-coding https, because a local test
server speaks http and the point is to run the real client against it.
`FetchResult`, `fetchJSON`, `fetchAllIssues` and `fetchComments` are exported so
the tests can drive the stack from its real entry points.
Coverage 76.xx -> 89.91 lines, 78.xx -> 80.75 branches, 75.xx -> 90.86
functions, 0 failing. Thresholds ratcheted 76/78/75 -> 88/79/89; none lowered
and nothing added to coverageGate.ignore.
No test contacts the real GitHub API and none mutates a real issue.

Greptile SummaryExpands pm-github failure-surface coverage via a local HTTP mock GitHub server and minimal production seams for testability.
Confidence Score: 5/5Safe to merge; the prior Windows pm.cmd spawn issue is fixed and no blocking failures remain. Every spawnSync(PM_BIN) path in the new handler tests supplies PM_SPAWN_OPTS with shell on win32; no remaining blocking defect from the prior thread or incomplete fix.
|
| Filename | Overview |
|---|---|
| index.ts | API base override, scheme-aware transport, GraphQL URL from base, and internal exports for HTTP-boundary tests. |
| test/handler-failures.test.ts | Handler failure-surface tests; all pm spawns use PM_SPAWN_OPTS (Windows shell fix applied). |
| test/http-boundary.test.ts | Real-client tests for retry, redirects, pagination, and transport errors against the mock server. |
| test/helpers/mock-github-server.ts | Ephemeral local HTTP GitHub mock and env helpers for boundary tests. |
| package.json | Coverage thresholds raised to 88 lines / 79 branches / 89 functions. |
| tsconfig.json | Enables stripInternal so @internal test exports stay out of published .d.ts. |

- Around line 216-228: Harden githubApiBase so PM_GITHUB_API_BASE is accepted
only for loopback HTTP test servers, or under an explicit opt-in for other
origins; reject unsafe unvalidated or plain-HTTP production overrides and retain
the default GitHub HTTPS origin. Normalize the returned base by removing
trailing slashes so request paths do not contain duplicate separators, while
preserving call-time environment evaluation.
- Around line 251-256: Rename the redirect block’s inner `let target: string`
variable to a distinct name, preserving the outer URL `target` used for
transport selection and request creation; update all references within that
redirect path accordingly.
In `@test/handler-failures.test.ts`:
- Around line 149-163: Update the “runValidate flags an inaccessible repo and
exits non-zero (NOT_FOUND)” test to assert that the rejected error is a
CommandError with exitCode equal to EXIT_CODE.NOT_FOUND, while retaining the
existing HTTP 404 message check; use the existing CommandError and EXIT_CODE
symbols rather than only validating the error message.
- Around line 338-339: In test/handler-failures.test.ts, add a small asserting
createTask helper modeled on createLinkedItem that runs the task-creation
spawnSync and validates its status. Replace every bare task-creation spawnSync
call, including the occurrences in the noted setup sections, with
createTask(root, …) so setup failures are reported immediately.
- Around line 93-94: Update the `spawnSync` calls in
`test/handler-failures.test.ts`, including the call near the parsed list and the
matching calls near lines 949 and 998, to reuse `PM_SPAWN_OPTS` while preserving
the UTF-8 encoding option. Ensure failures retain the existing
assertion/error-reporting path instead of attempting to parse invalid stdout
blindly.
In `@test/helpers/mock-github-server.ts`:
- Around line 36-38: Correct the documentation near the mock GitHub server
handler behavior: remove the claim that handler exceptions surface through the
server’s error event, unless the request error-handling logic around the caught
handler exception explicitly records or re-emits them for tests. Keep the
existing 500 response and socket-destruction behavior unchanged.

Three spawns passed a bare `{ encoding: "utf-8" }` while every sibling call in
the same file passed PM_SPAWN_OPTS, which adds `shell: true` on win32. That
matters because PM_BIN resolves to `pm.cmd` there and a .cmd cannot be executed
without a shell, so those three would fail while the surrounding init/create
calls succeeded — leaving linked-item id resolution and the post-apply listing
silently broken on Windows only.
Fixed all three (list-all at two sites, list at one) rather than only the line
review pointed at, and confirmed no remaining `spawnSync(PM_BIN, …)` in the test
tree omits the opts.
This is the same class of defect as the audit:prod scripts that shipped
POSIX-only forms across this fleet: a platform-conditional detail that is
invisible on the development platform.

…token
Review identified a genuine security hole that I introduced and that my own
reasoning had missed. I had argued the redirect guard made the override safe
because it drops the token cross-origin. That is the wrong analysis: the guard
only covers REDIRECTS, and the base *is* the origin — the very first request
already carries the resolved GITHUB_TOKEN. An unvalidated override read from the
ambient environment, combined with the http/https dispatch added for the local
test server, was therefore a token-exfiltration and TLS-downgrade primitive:
anything able to set an env var for this process could point authenticated
GitHub traffic at an attacker host in plaintext.
githubApiBase now accepts only what the tests actually need:
- https anywhere (no credential exposure on the wire), or
- http ONLY for loopback (127.0.0.1, ::1, [::1], localhost), which cannot
leave the machine.
Anything else throws rather than being silently ignored, so a misconfiguration
is loud instead of quietly redirecting authenticated traffic. A non-URL value
throws too, and a trailing slash is stripped so `${base}/repos/...` cannot
produce `//repos/...`. Six tests pin the constraint, including that
`http://127.0.0.1.evil.example.com` is rejected — a hostname that a naive
prefix or substring check on "127.0.0.1" would have allowed.
Also from the same review:
The redirect block shadowed the outer parsed `target` URL with a `let target:
string`. It worked only because nothing read the outer binding first, so a later
edit referencing the parsed URL would hit a runtime TDZ ReferenceError rather
than a build error. Renamed to `redirectUrl`.
A test named "...exits non-zero (NOT_FOUND)" asserted only the message, so a
regression remapping the exit code would still pass. It now asserts exit 3.
Setup `pm create` calls ignored their exit status, so a broken fixture surfaced
as "All 2 item(s) failed" and read as a product bug. They now go through a
`pmSetup` helper that fails loudly with the command and stderr.
The mock server's docstring claimed a throwing handler surfaces via the server's
`error` event. Nothing re-emits it — the error becomes a 500 body and a destroyed
socket. Corrected rather than left as a false promise.
`withEnv` moved into the shared test helper instead of being duplicated, since
both suites now need it.

Round 3 pushed — six findings from the concurrent CodeRabbit review, all six fixed, and one of them is the most important finding of the whole session. Major (security): I opened this PR explicitly asking reviewers to attack this override, and argued it was safe because the redirect path drops the token cross-origin. CodeRabbit's rebuttal is exactly right and I had missed it: the same-origin redirect guard does not help, because the base is the origin — the very first request already carries the resolved

Review made a point I had not accounted for: this package publishes `types: dist/index.d.ts` with `declaration: true`, so exporting internals purely for testability turns them into public API compatibility commitments. Consumers would be entitled to depend on FetchResult, fetchJSON, fetchAllIssues, fetchComments and githubApiBase, none of which are meant for them. Rather than un-export them (which would give up the ability to drive the real retry/backoff/redirect/pagination code from a test, and with it most of the coverage this PR adds), each is now marked `@internal` and `stripInternal` is enabled. The functions stay importable from source, which is what the tests use, while the published `.d.ts` advertises nothing about them. Verified rather than assumed: built the declarations twice, with stripInternal on and off, and diffed them. The flag removes EXACTLY those five declarations and nothing else, so no genuine public API was stripped as a side effect. Two of the five carried `//` line comments rather than JSDoc blocks, so an `@internal` tag would have been invisible to the compiler. Those were converted to real JSDoc blocks preserving their original wording. githubApiBase keeps its long `//` security rationale above the block, since that documents a constraint a future reader must not relax. Coverage 89.99 -> 90.04 lines, 80.95 branches, 90.86 functions. Gate exit 0, fail 0, pack:dry-run clean at 13 files. Refs pm-github-n3z3

Round 4 pushed — addressing the public API question, which was the second thing I asked reviewers to attack and the one still outstanding. CodeRabbit was right about the premise I had not accounted for: this package publishes I did not take the suggested route of un-exporting them and testing through the public command interfaces, and I want to be explicit about the trade-off: doing that gives up the ability to drive the real retry/backoff/redirect/pagination code directly, and with it most of the coverage this PR exists to add. Exercising a 429-with- Instead each seam is marked Verified rather than asserted, because a blanket strip flag is exactly the kind of thing that quietly removes more than intended: I built the declarations twice, with the flag on and off, and diffed them. It removes exactly those five declarations and nothing else. Two of the five carried Every comment on this PR is voted on and answered. Greptile is at 5/5, "safe to merge".

pm-github-n3z3 tracked raising sync coverage off its 76% measured floor. The work is complete: 90.04 lines / 80.95 branches / 90.86 functions against thresholds ratcheted to 88/79/89, driven through a local HTTP GitHub server so the retry/backoff, redirect, pagination and partial-failure paths execute for real rather than through a mocked client. Closed inside the PR rather than after merge, matching the convention in this fleet: the tracker item and its close land in the same squash commit as the work it describes, so main never carries a shipped change with an in-progress tracker. changelog:check stays green without regeneration. The package is already at 2026.7.29 and tag v2026.07.29 exists, so the prepend window (--since-previous-tag --until-release-tag) does not include this close; it belongs to the next release section, which the release job generates and commits.

Thanks — and specifically for verifying the changelog deferral against the actual tag object rather than taking my word for it. That is the check that mattered here. One piece of context worth carrying forward, because it is the failure mode this disposition is designed around: regenerating the changelog at close time looks correct and is the intuitive move, but in this fleet it corrupts an already-published section.

pmSetup loses the failure reason when the process never spawns.
If spawnSync can't launch PM_BIN at all (e.g. ENOENT), result.status is null and result.stderr is typically empty — the assertion message becomes pm setup failed: pm create task X\n with no actual reason, even though result.error holds it. createLinkedItem's own inline assert (line 93) already falls back to r.error?.message ?? r.stderr; pmSetup should do the same so it doesn't reintroduce the exact "opaque failure" problem it was created to fix.
🔧 Proposed fix
assert.strictEqual(
result.status,
0,
- `pm setup failed: pm ${args.join(" ")}\n${result.stderr ?? ""}`,
+ `pm setup failed: pm ${args.join(" ")}\n${result.error?.message ?? result.stderr ?? ""}`,

Assert status === 0 before JSON.parse-ing pm output in these read helpers. Same root cause across all three: a failing pm invocation currently surfaces as an opaque JSON.parse SyntaxError instead of naming the failing command, mirroring the diagnostic gap pmSetup/the create assert (line 93) were introduced to fix elsewhere in this file.

Why
pm-github is what the ecosystem relies on for two-way GitHub issue sync, so its correctness decides whether each repo's pm items can be trusted as the source of truth. The coverage gate was passing at 76 lines / 78 branches / 75 functions — but only because
coverageGate.thresholdswas pinned to that measured floor rather than toward the coverage mandate.The uncovered quarter of a 4332-line engine was its failure surface, which for a sync tool is exactly where the damage lives. The existing suite (
atomic,comments-sync,dryrun-preview,import-lock,link-deps,projects,smoke) covered the main flows; nothing covered what happens when GitHub says 429, or when a batch fails halfway.Approach: a real HTTP boundary, not a stubbed function
test/helpers/mock-github-server.tsruns a realhttp.createServeron an ephemeral127.0.0.1port and the client is pointed at it. Request building, response decoding, retry, backoff, redirect handling and pagination all actually execute — a test that replacedfetchJSONwith a fake would prove none of that.What is now covered
Retry and backoff
Retry-After, 5xx transient, and 403 primary rate limit (remaining=0) each retried and then succeedingmaxRetriesand throwingcomputeBackoffMs:Retry-Afterseconds→ms capped at 60s, the primary rate-limit reset window, exponential fallback (1s, 2s, 4s… capped), and a non-numericRetry-Afterfalling throughCredential safety
Locationis now a test failure rather than a latent bugPagination and transport
Link-header pagination with no silent truncation, plus the empty-page and single-page casesPartial-failure semantics — the ones that matter most for a sync tool
runExport --applycontinues past a mid-batch 422 to partial success (exit 0)runSynctolerates a 404 reading upstream state (skipped, not aborted)runValidateflags an inaccessible repo, and warns when the rate-limit budget is lowProduction changes (deliberately minimal)
Two were required to make the stack reachable from a test:
githubApiBase()reads aPM_GITHUB_API_BASEoverride at call time, not module-eval time, so a test can retarget per case without import-order coupling. Production is byte-identical when the variable is unset.requestOncedispatches on the URL scheme rather than hard-codinghttps, because a local test server speakshttpand the entire point is to run the real client against it.FetchResult,fetchJSON,fetchAllIssuesandfetchCommentsare exported so tests drive the stack from its real entry points.On the env override: it only changes the API base, and the redirect path already computes
sameOrigin(url, target) ? token : undefined, so the token is never forwarded to a different origin — verified by a dedicated test rather than by inspection.sameOrigincompares fullURL.origin(scheme + host + port), not just hostname.Coverage
0 failing tests. No threshold lowered, nothing added to
coverageGate.ignore.Verified locally (not claimed)
No test contacts the real GitHub API and none mutates a real issue. The only

Summary by cubic
Add a local HTTP GitHub server test suite that drives the real client (retry, backoff, redirects, pagination, partial failures), harden the API base override to prevent token leaks, and keep test-only exports out of published types. Coverage is 90.04/80.95/90.86 with gates at 88/79/89; no real GitHub calls.
