From 52d6746a4a67830ec8a24e2196822204ba843134 Mon Sep 17 00:00:00 2001 From: Jake Writer Date: Mon, 14 Sep 2026 16:52:05 +0000 Subject: [PATCH] ci: a repo-wide test pipeline, and the one check that gates merge on it (#772) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * ci: a repo-wide test pipeline, and the suites Camoufox was missing Nothing checked a pull request before this. `build.yml` runs on tags and takes about forty minutes, and `lint.yml` ran a single static script, so a change could reach main having had no browser suite run against it at all. This adds one pipeline, driven identically from a pull request, a push to main, and -- through `workflow_call` -- any caller that needs to test a specific browser version, so there is exactly one definition of "the tests pass". resolve ──┬─ static ────────── tribal rules, skiplist, self-tests ├─ pythonlib ─────── the package's own tests └─ build ──┬─ playwright upstream × 6 shards (conformance) ├─ playwright vendored (regression) ├─ native ───────────── leaks, contexts ├─ patch guards ─────── one per spoofing patch ├─ build-tester ─────── 8 fingerprint profiles └─ sundial ──────────── stealth grade (off, see below) │ summary ──► one comment on the PR Two Playwright suites, because they answer different questions. `tests/` is a frozen ~v1.55-era fork carrying roughly 1800 lines of Camoufox adaptations, so every test in it has a known prior outcome: that is the regression check. The upstream suite is fetched fresh at the tag `ci/versions.py` resolves and runs unmodified, which is the conformance check -- `ci/pw_camoufox_plugin.py` adapts the environment around it rather than editing it, hooking BrowserType at the _impl layer so upstream can refactor its fixtures freely. `native-tests/` covers what neither can ask about: that resource cost does not scale with launch count (the shape an FD or socket leak actually has), that two contexts in one browser get different fingerprints while two pages in one context get the same one (get this wrong and per-context injection silently degrades to process-global, which passes every single-context test there is), and that decisions already made stay made -- `ci/tribal-rules.yml` lists them with the issue or PR that settled each. Cost is tiered so a two-second lint failure never reaches a build, and a driver-only pull request never builds at all: it fetches the published release and tests against the build users are actually running, a minute instead of seventy. Merges gate on one required check, `All tests passed`, so the branch-protection list does not need editing every time a suite is added or resharded; `ci/branch-protection.json` holds the settings so they are reviewable rather than lore. **The stealth check ships disabled** (`ci/sundial.yml: enabled: false`). It drives a private detection suite, and the deployment it talks to predates that suite's score mode; an older one ignores `?score=1` and posts the entire report -- every vector's id, name, brief, source and value -- to whatever collector asked. Receiving that on a public runner and discarding it afterwards is not the same guarantee as never being sent it, so while the flag is false the job is not scheduled, no credential enters a runner, and `run_sundial.py` refuses a hand-run too. When it is enabled, `redact()` publishes a grade and counts against a runtime whitelist and refuses anything that is not already aggregated. Also included: the fixes these suites exposed on a clean runner -- build-tester hashing canvas pixels rather than a prefix of the data URL, the virtdisplay cleanup when Xvfb has already died, a juggler sandbox released on frame destroy rather than only on navigation, and the pythonlib geometry and version-floor corrections. `lint.yml` is removed because the static job absorbed its one check. Verified locally: ci/tests 68 passed, tribal rules 24 passed, pythonlib 209 passed, input-dispatch clean, `ci.versions` resolves 152.0.4/beta.31 against playwright v1.61.0, and `ci.summarize` folds a run to "all suites passed".

Three separate plumbing bugs, none of them in a test. **Hidden files.** `actions/upload-artifact@v4` excludes dotfiles unless told otherwise, and every result we write lives under `.ci-work`. The jobs whose `path:` was a list containing a glob uploaded nothing at all -- the Playwright suites and the leak suite each wrote their evidence and then had it silently dropped: evidence -> .../.ci-work/results/playwright_vendored.json (fail, 1203 tests) ##[warning]No files were found with the provided path: .ci-work/results/ .ci-work/junit-*.xml. No artifacts will be uploaded. **Common root.** Where a list did upload, the second entry moved upload-artifact's common root from `.ci-work/results/` up to `.ci-work/`, so the JSON arrived at `results/build_tester.json` instead of the artifact root. The summary merges every `results-*` into one directory and `load_all()` globs a single level, so the file was there and invisible. build_tester passed and was reported missing. Every `results-*` artifact now uploads exactly `.ci-work/results/`, with diagnostics (junit XML, the build-tester graded tree) split into their own `diagnostics-*` artifacts that the summary's `results-*` pattern ignores. `include-hidden-files: true` everywhere that touches `.ci-work`. **A required name nothing writes.** `static` was in the required list, but it is a job, not a suite -- no runner writes a result by that name, so summarize reported it missing on every run including a wholly green one. The suites that job runs are the pipeline self-tests, which write no result, and native_rules, which is required by name. The job is already covered: the gate fails on any job that is not success. Three guards, each verified by reintroducing the bug it catches: - results-* artifacts upload exactly one path, so nothing nests - anything touching .ci-work sets include-hidden-files - every required name is one some runner can actually write This changes no test. The real failures the first run found -- 6 in the vendored suite, plus upstream shards 1 and 5 and the leak suite -- were masked by the above and should now be reported rather than swallowed. ci/tests 71 passed.

Those two sets differ exactly when a process outlives its parent: it stops being our child, `settle()` sees nothing left and returns at once, and anything still winding down is reported as leaked. `glxtest` does this on every launch; it is spawned by Gecko, its parent exits first, and it needs a moment. So settle on the set the assertion actually uses. This is a grace period, not an exemption -- a process that is still there when the timeout expires fails the test exactly as before, and no name is special-cased. **Playwright renamed a protocol method the tracing tests spelled out.** `Page.waitForEventInfo` is `Page.__waitInfo__` in newer versions, so two tracing assertions failed on a name, not on behaviour. The suite is pinned to a range (`playwright<1.63`), not a version, so hard-coding either spelling is wrong. Normalised in `get_trace_actions()`, next to the comment about the last time Playwright moved this data -- the tests care which actions ran and in what order, not what Playwright calls them this month. Neither of these was Camoufox misbehaving. Still failing, and genuinely about the browser or by design -- triaged next: navigation popup load state, locator handler visibility, clock pause off by 1ms, websocket close reason, and the three upstream ones (request headers, worker locale, screencast viewport) which all look like deliberate spoofing divergence and probably belong in the skiplist with a stated reason. ci/tests 71 passed, tribal rules 24 passed. Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_01K1UY3f8gm2jA1J23C3ew9s * fix: the failures the new pipeline found, and the flake that hid them Eleven gates were red on PR #9. Each one is now either a fixed defect or an entry that says why the test cannot apply here -- nothing is silenced. One real browser bug, found by the conformance suite: The compositor-backed screencast added in fa8a935 reported the *scaled frame* size as the viewport. Playwright's Firefox delegate maps deviceWidth/Height straight onto the client-visible viewportWidth/viewportHeight, and every other backend fills them from the page's viewport -- the native path right below it sends pageWidth/pageHeight, clamped to the viewport and never scaled. So a client asking for a 500x400 frame of a 1000x400 page was told the viewport was 500x200, and asking for a frame *larger* than the page reported a viewport larger than the page. Confirmed against the built binary, fixed, and confirmed again: 11 screencast and video tests pass, where the requested size no longer moves the reported viewport at all. Four stale expectations in the vendored suite. All four pass in upstream's v1.61 suite against this same binary, which is what identified them as the suite's problem rather than the browser's: websocket Firefox no longer collapses a refused handshake to CLOSE_ABNORMAL; it reports the HTTP status, like the other engines. The handler also set a settled future twice, which surfaced as a suite ERROR rather than a failure. navigation Firefox now reports a window.open('') popup as "complete". The old assertion also mis-parsed -- the conditional bound to the whole assert, so the non-Firefox arm compared nothing. locator expect().to_be_visible() kept re-arming the locator handler the click was still waiting to see finish, so the check meant to observe the interstitial kept it alive. One-shot is_visible(). page_clock resume() before reading the clock added the real second spent in wait_for_timeout back, landing at 1001 -- one millisecond out, every time. Two upstream tests that encode a stock-Firefox quirk this fork does not reproduce, now in the skiplist with the reason: A worker inheriting the context locale -- upstream expects en-US from a ru-RU context, citing playwright#38919, because stock Firefox applies the locale to the page and not to its workers. Camoufox sets it below that layer, so matching upstream would mean reintroducing a main-thread/worker disagreement that anything looking in both places gets for free. "Firefox" in the User-Agent -- the bare binary advertises its own build token; the Python package replaces it when it injects a fingerprint. The vendored suite already asserts what this layer can promise. And three pieces of the harness that were reporting badly: A profile that asked for llvmpipe is no longer graded as headless. camoufox's own preset pool ships "llvmpipe, or similar", so when that preset is drawn, reporting it is the WebGL spoof working -- and grading it a failure made this gate fail at random depending on which presets the run happened to draw. The check still fails on a software renderer the profile did not ask for, which is the case it exists for. junit ids put a test's class in the path (test_page_clock/TestWhileRunning.py ::test_should_pause), naming a directory that does not exist -- so the id could not be fed back to pytest and no skiplist entry could match it. A `test:` skiplist entry was compared for exact equality against a node id that always ends in [firefox], so every such entry was a silent no-op: the test went on running and failing while the list read as handled. Finally, `mach bootstrap` pulls toolchains from Taskcluster, and a connection reset there failed the whole pull request (run 34673115086). ci.run_prepare retries the two steps that download things, and only when the failure reads as transient -- a failed patch hunk still fails on the first try, because retrying a broken tree only spends a runner to reach the same answer.

Both claims now match what is running. The substantive change is separating the two halves of the guarantee, because only one of them is enforced by the server: `guest` is refused the private-vector bundle by sundial's middleware, and this repository refuses to process anything that is not a score payload. What is still missing is a server that refuses the *request* -- which is what the `ci` role adds, and why the upgrade path is worth keeping written down rather than implied. Also documents ci.run_prepare, since "the build retries" is the kind of thing that needs its limits stated: the network, and nothing else.

They are indistinguishable by inspection, and the gate only knew how to use it as a password, so a repository holding a key would have failed to log in with no hint as to why. Try the key route first, since it needs no username and so nothing has to be kept in step with whatever `GUEST_USER` was set to, and fall back to the form. When the secret really is a password the only cost is one extra request that 401s. If both routes fail the error names both attempts and says what the secret is supposed to be. Also sends browser headers on every request rather than `User-Agent: camoufox-harness`. Cloudflare sits in front of this host and refuses a document request from a non-browser agent before it reaches sundial at all, which produces a 403 that looks like a permissions problem and is not one. test_a_disabled_gate_makes_no_request now makes every route out fatal -- authenticate() and both login functions, not just the one main() used to call -- so the kill switch cannot be bypassed through a path the test does not watch. Mutation-checked: making the gate ignore `enabled:` fails it. Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_01K1UY3f8gm2jA1J23C3ew9s * fix(ci): never let run_prepare invent a success `--attempts 0` would have fallen straight past the loop bound and returned 0 without running the step at all, which is the one answer it must not invent. Clamps to one attempt and makes falling out of the loop an assertion rather than a bare success. Also corrects a direction in the screencast comment: the native path it contrasts with sits above _startSnapshotScreencast, not below it.

That is now asserted, because it is the property the pass rate depends on and nothing was checking it. If sundial grows a tenth section, every check in it used to fold into "out of scope" -- measured, never gated, and indistinguishable in the summary from a category someone had deliberately decided not to gate. That answers "does Camoufox claim this?" by default, in the only direction that never fails a build: a stealth blind spot that reads as a clean run. The count is now carried separately and fails the gate, with a note saying to put the new section in one list or the other. Only ever a count -- which category, like which vector, does not leave redact(). Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_01K1UY3f8gm2jA1J23C3ew9s * fix(ci): stream the prepare log, and make its timeout real Two problems with capturing the output of `make dir` / `make mozbootstrap` instead of streaming it. The visible one: the step printed nothing for minutes while aria2c pulled a 500MB tarball, which looks exactly like a hung job. The one that mattered: draining the pipe on the calling thread blocks in readline until EOF and only *then* reaches proc.wait(timeout=...), so a step that wedged without printing anything -- a stalled download, precisely the failure this module exists for -- would never have been timed out at all. The reader now runs on its own thread, so output appears as it arrives and the timeout covers a silent hang. Both are asserted against real processes: stdout and stderr both survive into the text the transient-classifier reads, and `sleep 60` under a 2s timeout dies in 2s with exit 124 rather than reporting success.

Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_01K1UY3f8gm2jA1J23C3ew9s * docs(ci): the stealth job comment described the role we do not have yet It claimed the credential is for a role sundial refuses to serve a report to. That is the `ci` role, which is not deployed. Says what is actually true of `guest` instead: the request asks for counts, the role cannot load the private vectors, and the gate refuses a payload that is not a score. Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_01K1UY3f8gm2jA1J23C3ew9s * test(ci): name what this section actually asserts The heading said "the score-only `ci` role" and the docstring said the gate runs as a role sundial refuses to serve a report to. Neither is true yet -- that role is not deployed. What the tests actually pin is that score mode is a requirement rather than a preference: a full report is refused whoever asked for it. Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_01K1UY3f8gm2jA1J23C3ew9s * fix(ci): the sundial credential must not ride out on an error message Whatever reaches result.note() is written to the results artifact and posted as a pull request comment. An exception raised inside urllib can carry the URL that produced it -- and for the token route that URL *is* the credential, percent-encoded in the query string. A 401 from a stale key would have published the key. Every string built from an exception now goes through scrub() first, which removes both the raw secret and its percent-encoded form. The message still says which routes were tried and what the secret is supposed to be, so a real misconfiguration is still diagnosable from the log alone. Mutation-checked: with the replacement removed, both new tests fail. Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_01K1UY3f8gm2jA1J23C3ew9s * docs(ci): say which role the private-vector gate actually blocks "serves that bundle to nobody else" read as though sundial withheld the private vectors from everyone. It withholds them from `guest` specifically -- admin and private still get them -- which is the whole reason CI authenticates as the least privileged account rather than whichever one was to hand. Verified against the deployed middleware: guests get a 200 with a no-op body, not a 404. Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_01K1UY3f8gm2jA1J23C3ew9s * docs(ci): the Cloudflare 403 is narrower than the comment claimed It said any non-browser User-Agent is refused. In fact `POST /__auth/login` worked for months with `User-Agent: camoufox-harness` -- the block tracks document-shaped requests, which is what `/automated?key=` is. Browser headers everywhere are still right, but as "cheaper than remembering which hop is which", not as a fix for an outage that was never happening. Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_01K1UY3f8gm2jA1J23C3ew9s * fix(ci): verify the sundial role instead of assuming it The CI log for the first real run says `sundial auth OK (automation key)` -- the stored credential is an automation key, not a form password. Which matters more than it sounds: sundial's `/automated?key=` resolves to the **private** role when handed the private key and to `guest` when handed the guest one, and the two are indistinguishable by looking at them. `private` is served the private vectors. So the guarantee this gate has been documenting -- "CI runs as a role sundial withholds the vectors from" -- was resting on whoever set the secret having picked the right key. redact() does not help here: it governs what this repository *publishes*, not what the browser is *given*, and the thing being prevented is a public runner holding the vectors at all. The gate now reads sundial's own /__auth/me and refuses to open the browser unless the session is a role the vectors are withheld from. Not knowing the role counts as not safe: an absent or unreadable endpoint fails closed, because the alternative is loading them on the assumption that the credential was right. Probed live: a bogus cookie yields no role and the check refuses, as it should. The positive case is what the next run confirms -- and if that credential turns out to be the private key, this goes red, which is the correct and useful outcome. Also corrects the Cloudflare comment, which I had just rewritten on a false premise. The form-login route was never exercised in CI (the gate shipped disabled), so "POST /__auth/login worked for months with camoufox-harness" was unfounded. What is measured: /automated?key= answers 401 with a browser User-Agent and 403 with urllib's default -- and since that is the route the real credential uses, the browser headers were load-bearing, not cosmetic. Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_01K1UY3f8gm2jA1J23C3ew9s * fix(ci): record the sundial role in the evidence, not just in the log `result.metrics["sundial_role"]` was set before the scan and then thrown away: redact()'s output replaces result.metrics wholesale a few lines later. The check itself was unaffected -- it ran, and it fails closed -- but the saved artifact did not say which role had been confirmed, which leaves "the vectors were never served to this session" unverifiable after the fact. That is most of the reason to record it. Caught by reading the artifact the live run actually published, not by the 105 tests, none of which exercised gate() end to end. There is now one that does, and it fails when the re-assignment is removed. Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_01K1UY3f8gm2jA1J23C3ew9s * test: delete the vendored Playwright fork, keep only what is ours `tests/` held a fork of a ~v1.55-era playwright-python suite, run in CI as `playwright_vendored` alongside upstream's own suite. Measuring the two against the same binary says the fork was strictly the weaker of them: * 73 of the 74 tests it skipped as "Not supported by Camoufox" PASS in upstream's copy. Those skips predate main-world execution and were never revisited, so the fork was asserting the browser is worse than it is. * Of its passing tests, eight had no upstream counterpart. Six were genuinely Camoufox-specific; the other two were tests upstream had since renamed. * Everything else was upstream code, one generation stale, run twice. So the fork goes, and the six tests that were doing real work become `tests/camoufox/` -- three modules that `ci/suite.py` overlays into the fetched upstream checkout, where they run against its conftest and its server at whatever tag was resolved. Nothing frozen, so nothing to go stale. Two of them take over from skiplist entries that had been pointing at the fork: * the worker locale. Upstream expects a worker NOT to inherit the context locale (playwright#38919); Camoufox sets it below that layer, so its workers agree with the main thread. A page/worker disagreement is a free signal, so the replacement asserts they match rather than hardcoding one string. * the User-Agent. The bare binary advertises `Camoufox/`, not `Firefox/`, and only the Python package rewrites it. The replacement asserts a well-formed Gecko token and, more usefully, that the wire and the DOM agree on it. A skiplist entry that hands its job to another test now says so in a `replaced-by:` field, and `ci/summarize.py` fails the run if that file does not exist -- otherwise a rename quietly turns "covered elsewhere" into "not covered". Also here, because deleting the fork exposed them: * `tests/local-requirements.txt` was the only thing holding the suite below pythonlib's `playwright = "<1.63"` ceiling, and it is gone. `ci/versions.py` now applies that ceiling directly, so a future Firefox bump cannot silently resolve to a client the shipped package refuses to install. * the pytest header named `/skiplist.yml` whatever it had actually read. Since ci/suite.py copies the plugin into the checkout, that was a path with no file at the end of it -- misleading precisely when someone is chasing down a skip. It now reports the file it loaded. * the summary line printed "Camoufox 152.0.4 ... against Playwright v1.61.0, which targets Firefox 151.0", which reads like a misconfiguration. Playwright trails Firefox and skips generations -- it pinned 151 then 153, never 152 -- so it now says which rule picked the tag and that the browser is Firefox 152. `make tests` runs the one suite. Verified: the three overlaid modules pass against 152.0.4-beta.31 (8/8), the overlay refuses to shadow an upstream module and is idempotent across a reused checkout, and both new guards were mutation-checked. ci/tests: 112 passed. Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_01K1UY3f8gm2jA1J23C3ew9s * feat(ci): a local way to ask where the stealth failures are "Which five sundial checks failed?" has no answer in CI, and the reason is worth writing down rather than rediscovering: score mode's payload is buckets keyed "|" holding two integers each. It carries no check names and no ids, so a failing check's identity is not something the gate discards -- it is something sundial never sends. No artifact, log or sealed report can recover it. What the payload does know is which category the failures are in, and the gate was throwing that away too. `--explain` prints a per-category breakdown, and: * it prints, never records -- `result` is untouched, so the artifact still carries only `_PUBLISHABLE`; * it is refused outright under GITHUB_ACTIONS, before anything is sent. A category table is not a vector, but "Graphics 3/17" is the most useful single fact an adversary could take from a public log, which is precisely why redact() does not publish one; * it says in its own output that names need --allow-full-report and a role sundial serves full reports to, so a reader does not mistake the category view for the whole answer; * an unclassified category is flagged there too, on the same rule the gate uses -- a new sundial section must not default to ignored. Also corrects ci/README.md, which claimed "identities in the results file are HMACs". They are not, and have not been: redact() ships no per-check rows at all, deliberately, because a map of HMACs still says how many distinct checks fail and lets a reader follow one across releases. The README was describing a weaker guarantee than the code actually makes. The CI refusal is mutation-checked. ci/tests: 116 passed. Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_01K1UY3f8gm2jA1J23C3ew9s * fix(ci): 193 of the 202 tests the skiplist skipped actually pass The skiplist was wrong, and wrong in the way that matters: it claimed the browser could not pass tests it passes, and the stated reasons made that look checked. Where it came from: the first version of ci/skiplist.yml took all nine `tests/async/*.disabled` modules from the vendored suite -- a 1:1 match, nothing independently derived -- and gave each a plausible justification without running any of them. That is the exact thing the file's own header calls "a regression wearing a disguise", committed in the commit that wrote the header. Ran every entry with the skiplist disabled, against 152.0.4-beta.31: test_element_handle.py 59 skipped 0 fail test_popup.py 26 skipped 0 fail test_dispatch_event.py 12 skipped 0 fail test_check.py 9 skipped 0 fail test_launcher.py 9 skipped 0 fail test_focus.py 6 skipped 0 fail test_fill.py 3 skipped 0 fail test_click.py 71 skipped 2 fail client_certificates 5 skipped 5 fail (two individual tests) 2 skipped 2 fail Seven of nine modules failed nothing at all. 193 of 202 passed. The suite was reporting 1339 passing while silently excluding 193 more that also pass -- and nothing would have caught those 193 regressing. Some reasons were not just over-broad but wrong. test_popup.py was skipped for "Camoufox resolves the User-Agent from its fingerprint config, so an arbitrary override does not and must not stick"; the two UA tests in it pass, because the bare binary under plain Playwright does honour `user_agent=` -- the fingerprint resolution is in the pythonlib wrapper, which this suite does not use. The neighbouring test_request_headers_should_work entry gets that distinction right, four entries earlier. test_dispatch_event.py was skipped for "Camoufox only emits trusted events"; that is true and those tests never assert isTrusted. So: 13 entries down to 5. test_click.py narrows from the module to the two tests that fail -- Playwright's stable-position wait polls the bounding box then dispatches instantly, and the humanized path spends real time travelling, so an animating button is clicked mid-flight (offset 100, expected 300). The client-certificate module stays whole: all five fail at the TLS layer, which is support that genuinely is not compiled in. The `[chromium]` and `[webkit]` patterns are deleted -- the runner pins `--browser firefox`, so they matched 0 tests and only made the list look more considered than it was. And the guard, because a reason is an assertion about the browser and nothing was checking it: ci/run_skiplist_audit.py runs every entry with the skiplist disabled and FAILS THE BUILD if a skipped test passes. It is cheap exactly because a correct skiplist is short -- 9 tests, 8 seconds -- so it runs on every PR in tier 3a and is a required gate. Mutation-checked both directions: exit 1 naming the newly-passing tests when a stale entry is re-added, exit 0 now. ci/tests: 118 passed, including that every shipped entry is actually auditable (a `pattern` entry cannot be, and now fails that test rather than riding along unverified).

Upstream v1.61 collects 2306 tests; that was 1584 of them. The other 722 -- `tests/sync/` (715), `tests/common/` (4), `test_reference_count_async.py` (2), `test_installation.py` (1) -- never ran, and unlike a skiplist entry there was nothing anywhere saying so. No reason was recorded because there was no decision: the vendored fork in tests/ carried `async/` and `async_imp/` and no sync suite, and this runner was pointed at the same shape without checking what upstream had. Same inherited shape as the stale skiplist, one level up. TARGETS now names `tests/async/` and `tests/sync/`. The sync API is a greenlet wrapper over the same Juggler traffic, so much of it duplicates async at the protocol level; it is here because pythonlib ships a sync API users actually drive, and the wrapper has its own timeout and reentrancy behaviour the async tests cannot reach. ISOLATED_TARGETS runs `tests/common/` and `test_reference_count_async.py` in a second pytest process, on the first shard only. They cannot share a process with the others: each calls sync_playwright()/async_playwright() inside the test body, which cannot start while the session fixtures hold a loop. Together all six fail with "Cannot run the event loop while another loop is running"; alone all six pass. They are worth the extra invocation rather than dropping, because ProtocolCallback objects accumulate when the browser never replies to a protocol message -- and this fork patches Juggler heavily, so that leak can be ours. EXCLUDED holds the one real exclusion with its reason: test_installation.py pip-installs playwright to check packaging, which exercises Playwright's release process and not this browser. A self-test requires every exclusion to carry a reason. And unclaimed() closes the level above the skiplist: if upstream adds a test path that is in neither set, the run errors instead of quietly getting narrower. It ignores assets/ and golden-*/ fixtures, and a self-test proves it catches a new tests/integration/. Verified against the CI-built binary: 2225 passed, 0 failed, 66 skipped, 2291 collected. ci/tests: 122 passed.

It was right to. `tests/async/test_browsercontext_client_certificates.py` was skipped as a whole module, reasoned as "client-certificate support is not built into the Camoufox binary". On the GitHub runner two of its five tests pass: test_should_throw_with_untrusted_client_certs PASSES test_should_work_with_global_api_request_context PASSES test_should_work_with_new_context fails test_should_work_with_new_context_passing_as_content fails test_should_work_with_new_persistent_context fails The split is not noise. Playwright offers client certificates two ways: playwright.request.new_context(client_certificates=...) the Node driver does the TLS handshake itself -- works, and those are the two that pass. browser.new_context(client_certificates=...) the BROWSER does the handshake -- and this build has nothing to do it with. So the reason was over-broad rather than wrong, and a module entry was exactly the shape that hid the distinction. Now six per-test entries, async and sync, naming the browser-side handshake specifically. Worth recording how the bad entry got written, because the mechanism matters more than the entry: locally all five fail, because this machine's Node/OpenSSL rejects the fixture server outright ("wrong version number"). That looked like uniform absence of support and it was not. A local run is a hypothesis; CI is the authority for what fails. The audit is what turned that from an opinion into a build failure, one run after the mistake. The sync entries assume the same split from identical test names; the audit will confirm or correct that on the next run rather than my asserting it from here.

In one process, whichever runs second breaks the other's loop. Measured, against the CI-built binary: tests/async alone 1526 passed, 1 timing flake the two fetch modules alone 102 passed async fetch + one sync module 14 failed sync module first, then async fetch 46 errors So sharding was not hiding anything -- async alone is clean -- and the fault is the mixing, not the size of the run. What makes this worth a structural fix rather than a retry budget: the damage lands in async FIXTURE SETUP, so it presents as "the fetch tests are flaky" -- a browser-shaped symptom for a harness-shaped cause -- and the retry pass then makes it vanish. Left alone, CI goes green with 50 silent retries, and the natural response to any that stuck would be a skiplist entry recording a browser failure that does not exist. That is the failure this branch has spent its last several commits removing. GROUPS now names three sets, each run in its own process: tests/async/, tests/sync/, and (tests/common/ + test_reference_count_async.py). The first two shard; the third is six tests and does not, because splitting it hands some shard an empty selection and pytest exits 5 for that. The pairing in the third group is measured, not assumed -- those two run together cleanly (6 passed). Retries stay inside their own group, for the reason the groups exist. Verified: 2225 passed, 4 failed, 66 skipped, 2295 collected, and 1 retry-passer instead of 50. All four failures are the two client-cert tests that go through playwright.request.new_context(), which fail only on this machine -- its Node/OpenSSL rejects the fixture server ("wrong version number"). They pass on the runner, which is why they are not skiplisted; the audit is what will hold that claim honest. Expect 2229/0 in CI. ci/tests: 124 passed, three of them pinning this shape -- async and sync in different groups, no target in two groups, and the small group unsharded.

That half works. The other half does not. Nothing else honours the input: ci.run_build / make read upstream.sh fetch-browser `python -m camoufox fetch`, whatever is current ccache key uses the resolved version (cosmetic) So `browser_version: 155.0` on a branch pinning 152.0.4 compiles 152 and judges it against the suite chosen for 155. It passes, it means nothing, and no output anywhere says the browser and the suite are describing different releases. For a gate whose entire job is to make an upgrade provable, that is the worst available outcome. The legitimate flow never had this in it: an upgrade to a new Firefox is a branch that edits upstream.sh -- that is what an upgrade is -- and resolution then reads it by default, so the build, the suite and the input cannot disagree. The mismatch only arises from a dispatch that asks for a version the branch does not pin. `--check-upstream` refuses that combination with a message saying what would have happened and what to do instead (bump upstream.sh). The workflow passes it, and a self-test asserts the workflow passes it, because a guard nothing invokes is decoration. Mutation-checked. Not fixed here, and deliberately: making the build honour an arbitrary version would mean synthesising an upstream.sh -- version plus release tag plus closedsrc_rev -- for a release that may not exist. Refusing the contradiction is the honest amount of machinery for it. ci/tests: 126 passed.

It downloads the current release, which is the right browser to judge a driver change against -- it is what users run. But the Playwright suite is chosen from upstream.sh, and those two agree only until an upgrade window opens. The sequence that breaks: the version agent bumps upstream.sh to Firefox 155 and that merges. No build of 155 is published yet. The next driver-only PR resolves its suite for 155, fetches the published 152, and tests the old browser against the new suite. It passes, and says nothing. Today they happen to agree exactly -- upstream.sh pins 152.0.4-beta.31 and the latest release is v152.0.4-beta.31 -- which is timing, not a guarantee, and precisely the kind of coincidence that hides this until the upgrade it is supposed to protect. So the fetch step now reports which build it installed and refuses a mismatch. Beta drift inside a generation is fine and expected: beta.30 against beta.31 does not change which Playwright tag is right, and demanding an exact match would fail every run between a bump and a release. A generation apart is not fine, and that is what is checked. Fails closed on input it cannot read, rather than passing by accident. Mutation-checked. A self-test asserts the workflow actually invokes it. ci/tests: 128 passed.

But the build job is deliberately skipped whenever the browser was fetched rather than compiled, and only that job writes a `build` result. summarize then reports `build` is required but produced no result file. A suite that did not run has not passed. which is the correct rule applied to a suite that was never supposed to run, and the gate goes red. That blocked every pull request touching only pythonlib/, ci/, tests/ or the documentation -- most of them, and precisely the cheap path ci/README.md advertises as "driver-only pull requests never build". It was never seen because this branch edits the Makefile and additions/, so its own runs always took the build path. The browser suites stay required either way: fetched or built, the browser is there and they run against it. `build` is the only one that follows. `test_build_is_required_only_when_the_browser_was_built` extracts the workflow's own `required=` assembly and runs it under bash for both values, rather than pattern-matching the shell -- the bug was a comparison that read as deliberate, and only running it says what it does. Mutation-checked: restoring `!= "skip"` fails it. Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_01K1UY3f8gm2jA1J23C3ew9s * fix(ci): sundial being down is a skip, not a verdict on the browser The stealth check drives a service on another host. Any failure reaching it -- DNS, a refused connection, the edge answering 502 for a minute -- came back as ERROR, failed the job, and failed the merge gate. So an outage over there blocked every pull request in this repository, including ones that had nothing to do with stealth, and the only fix available to a contributor was to wait. That is not a statement about the browser. When sundial cannot be reached the browser was not measured at all, so neither a pass nor a failure is true. It is now recorded as SKIP with the reason attached, the job exits 0, and `ci/summarize.py --allow-skip sundial` tolerates it: shown on the summary table with its own icon and its reason, and not a merge block. The line is drawn at whether sundial answered: down no HTTP reply at all (URLError, timeout, connection reset), or a 5xx, or a 429 -- the origin is broken or is refusing everyone. answered everything else. 401 is a bad credential, 403 is the edge refusing a non-browser request, and both are this repository's problem to fix. Skipping past those would turn a misconfigured stealth gate into a permanently green one. And an answer stays an answer further in: a role sundial would serve the private vectors to, a full report where a score was requested, a pass rate under the floor -- all still fail, as before. Both auth routes are tried, and the key route 401s whenever the stored secret is a password rather than an automation key. One real reply is enough to know sundial is up, so `authenticate()` reports an outage only when neither route got an answer. The skip note goes through `scrub()` like every other published string: the token route puts the credential in the URL, and a URLError carries the URL that raised it. `--allow-skip` is per suite and nothing else is on the list. Every other suite runs on the runner; none of them has this excuse. Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_01K1UY3f8gm2jA1J23C3ew9s * feat(ci): run the suite isolated first, and count what needs the main world The conformance suite forced `disableWorldIsolation` for every run. That made upstream's tests pass -- they assert upstream semantics, reading globals their own page scripts defined -- but it measured a mode nobody ships, and it produced no number at all for what isolation costs. Isolation is the reason this fork exists; running 2229 tests against it turned off says less than it looks like. Each group is now run up to three times: 1. isolated -- the configuration users get. A test reading a page-defined global fails here by design. 2. the same failures again, still isolated. A pass is a flake, and a flake must not be counted as a world difference. 3. what is still failing, with isolation off. A test that passes in 3 is a **main-world fallback**: it counts as a pass -- the browser does honour the contract -- and its identity is recorded in `metrics.main_world_fallbacks`, with the count on the summary table. That count is the isolated-world conformance gap. It is invisible in the pass/fail totals by construction, which is exactly why it has to be printed: a jump in it means the isolation boundary moved, and nothing else in this pipeline would say so. A test failing in *both* worlds is a plain failure, as before. `CI_WORLD` selects the world and defaults to isolated, so a plain `pytest -p pw_camoufox_plugin` by hand measures the browser as it ships. `_apply_world()` *clears* a stale `disableWorldIsolation` as well as setting it: the passes are separate processes inheriting one job environment, and a leftover flag would make the isolated pass quietly measure the main world -- which would silently zero the very number this is for. Two things this depends on, fixed here: Each group gets its own pytest cache. All three run in one checkout, and pytest only drops a `lastfailed` entry when that test is collected again and passes -- so with the shared cache the async group's rerun was selecting from a set the sync group had also written into. Depending on which groups had failed that meant re-running the whole group or selecting nothing at all. Per-group, `--last-failed` means what it says, and passes 2 and 3 can use it to name exactly the right tests. `ci/run_skiplist_audit.py` pins the MAIN world. The suite now counts a test needing the main world as a fallback rather than a failure, so a skiplist entry has to claim the test cannot pass in either world -- auditing under isolation would let an entry justify itself with a failure the suite would never have counted, which is the same class of untrue-but-plausible reason the audit exists to catch. Shard merging sums the fallback counts and unions the identity lists; taking the first shard's, as the generic metric merge did, would report a sixth of the number. Mutation-checked, along with the stale-flag clear. The first CI run on this is what establishes the real fallback count. The plugin's own note put it at roughly 37; that was measured a while ago and is not a promise.

CLAUDE.md was already pointing at CONTRIBUTING.md for "the full pipeline" that CONTRIBUTING.md did not mention. Since the premise of this work is that the rule in CONTRIBUTING.md was never enforced, leaving it unchanged left the rule describing the wrong thing. Both now say what CI does and what the one required check is. The template no longer asks for a screenshot: nothing checked that the browser in one was built from the branch under review, which is the whole reason the pipeline exists, and CI leaves its own report as a comment. The local commands stay, because running build-tester by hand while working on a spoofing patch is still the fastest way to find out whether it did what you meant. Several comments described this repository as containing an auto-update harness that is not in it: `ci/results.py` credited `verify.py` and "the repair agent" with computing the verdict that `ci/summarize.py` computes, and `ci/sundial.yml` and `ci/build-tester.yml` sited themselves relative to a `harness/policy.yml` nobody can open. Each now names what actually decides here and marks the harness as the out-of-repository caller it is. `run_sundial.py waive` says outright that the file it prints a stanza for is not in this repository, which is worth knowing before going to look for it. Also: PEP 8 blank lines around `resolve_verstr()`.

Most of that was a pass that could not have worked. Shard 4, both sharded groups: isolated (full) 335s + 331s 35 and 11 failures isolated retry 205s + 265s 0 recovered main world 19s + 12s 46 recovered The retry was there so that a flake could not be mistaken for a world difference. It cannot do that job: * These failures are deterministic. A test reading a global its own page script defined does not intermittently stop seeing it. * Failing that way is slow. The read returns undefined rather than throwing, so the test sits on a Playwright timeout -- which is why re-running 46 known failures cost nearly eight minutes while proving them in the other world cost thirty-one seconds. * Upstream already reruns. The `105 rerun` on that first line is every one of those 35 failures having been retried three times by the suite's own pytest-rerunfailures before the run reported them. A flake does not survive that, so there was nothing left for a fourth and fifth attempt to find. So: isolated, then the main world, then -- only for what failed in BOTH -- one retry. That last set is normally empty, so the retry is free on a healthy run and still answers the one open question on an unhealthy one: a test no world satisfies is either broken or flaky. It runs in the main world, where a pass means "not reproducible" rather than "needed isolation off", which is already known by then. A flake surviving upstream's three reruns and then passing in the main world would now be counted as a fallback rather than as a flake. That is the trade, and it is worth it: the count is reported, not gated, and no verdict moves. Also adds the guard that was missing between the phases. `--last-failed` with nothing previously failed does not select nothing -- pytest declines to filter, and runs the whole group. Unguarded, a group that passed cleanly under isolation would have been re-run end to end in the main world, silently replacing the result it was meant to refine. Both rerun passes are now behind a non-empty check, and a self-test asserts it of every `--last-failed` in the loop. Mutation-checked, as is the single-isolated-pass rule -- "retry it in the same world first, just to be safe" reads as obviously correct and costs eight minutes a shard. Expected shard time is now ~11 min: the isolated pass, which is the measurement, plus half a minute to resolve it. Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_01K1UY3f8gm2jA1J23C3ew9s * perf(ci): bound the isolated pass, which is where the timeouts come from Some isolated failures do not fail. They hang for the full 180s per-test timeout and are then rerun three more times, so one test can cost twelve minutes. The main-world baseline had zero timeouts across all six shards, so this arrived with isolation. Reproduced against a build, and the cause is not the harness: page script calls window.exposedFn() isolated -> HANG main -> resolves evaluate() calls window.exposedFn() isolated -> resolves main -> resolves `expose_function` installs its binding on the isolated world's global. Page script calling `window.fn()` looks at the page's own window, does not find it, and the call never reaches Python -- so a test awaiting the future that call was meant to resolve waits forever, because that await has no Playwright timeout behind it. evaluate() works because it runs in the same world as the binding. That is isolation doing exactly what it is for. A page that can reach an automation binding can detect it, which is the reason this fork exists. These tests assert a behaviour Camoufox deliberately does not have, and they cannot be fixed -- only recognised, which pass 2 does in about half a second each. What can be fixed is the price of recognising them. Pass 1 is a classifier: its only question is whether a test passes as Camoufox ships, and a test that hangs has already answered it. So pass 1, and only pass 1, is bounded: per-test timeout 90s. The slowest test in the entire main-world baseline was 30.4s of 2295; two exceeded 30s and none exceeded 45s. A Playwright action times out at 30s. Three times the slowest honest thing that happens, and half the previous bound. upstream's reruns off, via CI="". tests/conftest.py sets `reruns = 3` whenever $CI is set, and that is the only thing it reads $CI for. It is insurance that almost never pays out -- 2 reruns across all 2295 baseline tests -- and under isolation it turned every deterministic world difference into four attempts: 138 reruns in a single shard's isolated pass, recovering nothing. Note that `--reruns 0` as an argument would not work; conftest overwrites config.option.reruns in pytest_configure, so the environment is the only lever that holds. A hang now costs one 90s wait instead of up to 720s. A flake missed by not rerunning is not lost: it fails pass 1, passes pass 2, and is counted as a fallback -- noise in a reported metric, not a change in any verdict. Passes 2 and 3 keep upstream's conditions untouched. They are the ones deciding what an answer means, and they run against a handful of tests.

That part is correct and should stay: the published release does not contain this branch's browser changes, so testing against it would test a different browser than the one under review. Using the release is not the alternative. The alternative is not building the same thing twice. The build job now asks a narrower question first -- not "does this branch change the browser" but "has the browser changed since the last one we built" -- and answers it with a cache keyed on a hash of every input that can alter the binary: the same path list browser_changed greps for, plus this workflow, which pins the toolchain the build runs on. On a hit the 634 MB dist is restored and every build step is skipped, which is the difference between 24 minutes and about one. Two things that would otherwise have made this quietly wrong: A hit still has to report a `build` result. It is a required suite whenever the browser was built rather than fetched, and a required suite that produced no result is -- correctly -- a failure. Same trap as requiring `build` on a driver-only pull request, reached from the other side. The hit path writes one recording that the browser was restored and under which key, so "this run compiled nothing" is a fact in the evidence rather than an absence in it. No restore-keys. Everywhere else in this workflow a prefix match is right; a partly warm ccache is still warm. Here it would hand the test jobs a browser built from different sources while every suite reported on it looking perfectly healthy. The self-tests hold the two lists together: if a path is ever added to the browser_changed grep without being added to the cache key, a change there would neither force a build nor invalidate the cache, and the run would silently test a browser that predates it. Mutation-checked, along with the guards on each expensive step and the absence of restore-keys.

Measured on a real build, ccache reported a 98.63% hit rate (4167/4225), so almost none of those 24 minutes was compiling C++ -- it was Rust, linking libxul, and packaging, none of which a .js file affects. And there is no omni.ja to rebuild either. CI archives the UNPACKAGED dist/bin; omni.ja only exists in dist/camoufox/, which `mach package` produces and nothing here uses. In dist/bin, Juggler is loose files under chrome/juggler/ -- symlinks into the source tree, dereferenced into the artifact by `tar -ch`. Delivering new JavaScript is a copy. So the build cache is now keyed on a hash of the COMPILED inputs only. If that hash matches, the compiled half is identical by construction and this branch's resources are laid over the restored browser. The hash is the classification: there is no "did only JavaScript change?" diff, because a diff answers the wrong question -- it compares against the pull request's base, while what matters is whether the cached browser has the same native sources. Same hash, same binary, whatever the diff says. Two traps, both closed and both mutation-tested, because either one silently serves a browser that is not the one under review while every suite reports green: additions/juggler/ is not all JavaScript. It also holds the screencast encoder and the remote-debugging pipe -- 5 .cpp, 5 .h, 2 .idl, 3 components.conf, 4 moz.build -- compiled into libxul. Only the files jar.mn lists are treated as resources; everything else, including any extension nobody has considered yet, is native and forces a build. jar.mn is itself native, so a resource removed from it cannot leave a stale copy behind. The mapping is per-file, not a prefix. jar.mn maps TargetRegistry.js to content/TargetRegistry.js (a level added), content/FrameTree.js to content/content/FrameTree.js (preserved), and content/JugglerFrameChild.sys.mjs to content/JugglerFrameChild.sys.mjs (dropped). Two files in one source directory land at different depths. A prefix rule writes one of them to the wrong path and leaves the old copy in place. Verified against a real build rather than reasoned about: all 22 jar.mn entries resolve to files that exist in dist/bin, and overlaying this branch onto a dist built before it turns FrameTree.js from 0 occurrences of nukeSandbox to 1, with all 22 resources byte-identical to the branch afterwards.

That mechanism is real -- verified against a build -- but no upstream test has that shape, so it is not what hangs in CI. Running the full async suite isolated against a build names them: four tests, always the same four, all in tests/async/test_route_web_socket.py. 225 of 1509 fail under isolation; four of those hang. The general shape, which is worth stating because it will recur: a Playwright feature implemented by installing something on the page's global lands in the isolated world instead, so anything the PAGE originates never reaches the automation. route_web_socket replaces window.WebSocket from an init script; isolated, that replacement is in the sandbox and a socket the page's own script opens is never intercepted. expose_function puts its binding on the sandbox global, so page script calling window.fn() finds nothing -- called from evaluate() it works, which is why it does not hang. They hang rather than fail because the waits involved have no Playwright timeout behind them: a Twisted future from the test server, an asyncio future a binding was meant to resolve. Everything else isolation breaks fails at Playwright's 30s. One thing to flag beyond the test suite: the route_web_socket half is not a test artifact. Measured with a page whose own script opens a socket -- what a real site does -- the handler fires in the main world and never fires isolated. A user calling page.route_web_socket() against a real site gets no interception and no error. It is not fixable here, because the feature works by replacing a page global and that is exactly what an isolated world exists to prevent a page from seeing, but it deserves an issue of its own rather than a comment in a CI runner.

The bound works. tests/sync/ test_should_work_with_ws_close printed pytest-timeout's "+++ Timeout +++" banner at exactly 90s -- and the process then sat there for the remaining 1h50m. So the signal fires and the test dies; the process does not. pytest-timeout's signal method raises at the next bytecode boundary, and Playwright's sync API is parked in a greenlet switch that never reaches one cleanly, so the raise lands inside the dispatcher and wedges it. `--timeout-method=thread` fires reliably but kills the interpreter and takes the other ~1500 tests in the group with it. No per-test value bounds this, which is why lowering 180 -> 90 changed nothing. Declared rather than discovered, then. The isolated pass cannot learn that these hang without hanging, so ISOLATION_HANGS tells it: they are --ignore'd out of pass 1 and run directly in the main world, where they pass and are counted as fallbacks exactly as if isolation had failed them honestly. Coverage is not lost -- the same tests run, in the world that can run them. Verified in the same run: tests/async/test_route_web_socket.py::test_should_work_without_server isolated -> Timeout main -> PASSED Deliberately not ci/skiplist.yml. That list means "fails in the most permissive world", and run_skiplist_audit.py enforces it by running every entry with CI_WORLD=main and failing the build on any that pass. These pass there, so an entry would be rejected by the audit and would be untrue as written. The tests keep the two lists apart. The second half is the backstop, because the next unboundable hang will not be this one. Each pytest invocation was bounded at args.timeout, default 10800s -- three hours, against a job capped at 120 minutes. It could never fire: GitHub hard-killed the runner first, taking the junit and diagnostics uploads with it. Now --group-timeout, 1200s, roughly four times the slowest healthy invocation measured, and the job drops 120 -> 40. A wedge costs twenty minutes and still reports what it collected, instead of two hours and nothing. The browser bug underneath is real and is not a test artifact: route_web_socket replaces window.WebSocket from an init script, which under isolation lands in the sandbox, so a socket the page's own script opens is never intercepted and the caller gets no error. Filed as #775, with the native-interception fix that keeps it undetectable. When that lands these stop hanging and the declaration goes.

It went unnoticed because until now every run changed the browser sources and rebuilt instead -- the cache restored, the overlay ran ("overlaid 22 resource(s)"), and the step died one line later. The first pull request that did not touch the browser found it. Repack to a temporary name and mv it into place. That sidesteps the refusal, and means a repack that dies partway cannot leave a truncated archive where the restored one was. Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_01K1UY3f8gm2jA1J23C3ew9s * fix(ci): a six-test module cannot be sharded six ways The declared-hang pass ran with the shard filter still applied, so a shard that owned none of the module got: collected 6 items / 6 deselected / 0 selected ============================ 6 deselected in 0.05s =========================== pytest exits 5 on an empty selection and writes no junit, which is exactly what "the module did not run" looks like -- so the guard that exists to catch lost coverage failed three of six shards instead. The other three owned some of the six and passed, which is why it looked intermittent. Run it unsharded on the first shard, the way tests/common/ already is and for the same reason. Running the module whole also keeps its fallback accounting in one place rather than spread across shards that each saw a fraction of it. CI_SHARD is cleared rather than dropped: ci/_util.run() layers env over os.environ, so an omitted key would still inherit one. parse_shard() reads empty as "no shard", the same way _NO_UPSTREAM_RERUNS clears $CI. The rest of the run confirms the mechanism. On shard 3, which completed: tests/sync/test_route_web_socket.py::test_should_work_with_ws_close PASSED in 3.07s -- the test that wedged a runner for 1h50m two runs ago -- and the shard finished 386 passed, 0 failed, 0 errored. No shard hung. The whole run took 26 minutes against 2h35m, and the build was 53s against 24m now that the prebuilt cache can repack.

It is not a fork +of anything, so it cannot go stale; it runs against upstream's own conftest and +server at whatever tag was resolved. + +`tests/` used to hold a fork of a ~v1.55-era upstream suite. It was deleted after +measuring it against the same binary: + +- **73 of the 74 tests it skipped as "Not supported by Camoufox" pass** in + upstream's copy.

These failures are deterministic — +a test reading a global its page script defined does not intermittently see it — +and failing that way is *slow*, because the read returns undefined and the test +sits on a Playwright timeout rather than throwing. And upstream's suite already +ships `pytest-rerunfailures`: pass 1 reported `105 rerun`, which is each of +those 35 failures having been retried three times before the run even reported +them. A flake does not survive that. + +A test that passes in pass 2 is recorded as a **main-world fallback**: it counts +as a pass for the run, and its identity goes into +`metrics.main_world_fallbacks`, with `metrics.main_world_fallback_count` on the +summary table (summed across shards). A test failing in both worlds *and* on +retry is a plain failure. The fallback count is the isolated-world conformance +gap — watch it between runs; a jump means the isolation boundary moved. + +Both rerun passes are guarded on the failure set being non-empty, which is +load-bearing rather than tidy: pytest declines to filter when nothing it +collected previously failed, so an unguarded `--last-failed` runs the *whole* +group again — in the other world, silently replacing the result it was meant to +refine. + +### Why some isolated failures hang + +Not every isolated failure fails. Some wait forever, in both +`tests/async/test_route_web_socket.py` and `tests/sync/test_route_web_socket.py` +— and the two are not equally recoverable, which is the subject of the second +half of this section. + +The shape recurs, so it is worth stating generally: **a Playwright feature +implemented by installing something on the page's global lands in the isolated +world instead, so anything the page itself originates never reaches the +automation.** Two instances, both measured directly against a build: + +``` +page's own script opens a WebSocket isolated -> handler never fires main -> intercepted +page script calls window.exposedFn() isolated -> HANG main -> resolves +evaluate() calls window.exposedFn() isolated -> resolves main -> resolves +``` + +`route_web_socket` works by replacing `window.WebSocket` from an init script; +isolated, that replacement lands in the sandbox, so a socket the page opens is +never seen. `expose_function` installs its binding on the sandbox global, so page +script calling `window.fn()` finds nothing — though called from `evaluate()` it +works, which is why that one does not hang here. + +They **hang** rather than fail because the waits involved — a Twisted future from +the test server, an asyncio future a binding was meant to resolve — have no +Playwright timeout behind them. Everything else isolation breaks fails at +Playwright's 30s. + +Worth being clear that the `route_web_socket` half is **not a test artifact**: a +real site's WebSocket is not intercepted either, and the user gets no error +saying so. It is not fixable at this layer — the feature works by replacing a +page global, which is precisely what an isolated world exists to stop a page +from seeing. Tracked in [#775][ws-issue]; the fix is native interception below +the DOM object, which is also the only version of it that stays undetectable. + +[ws-issue]: https://github.com/daijro/camoufox/issues/775 + +So pass 1 is **cost-bounded**, and only pass 1: + +| Bound | Value | Why | +| --- | --- | --- | +| per-test timeout | 90s | the slowest test in the whole main-world baseline was 30.4s; only two exceeded 30s and none exceeded 45s. A Playwright action times out at 30s | +| upstream reruns | off (`CI=""`) | `tests/conftest.py` sets `reruns = 3` whenever `$CI` is set — the only thing it reads `$CI` for. The baseline recorded **2** reruns across all 2295 tests; the isolated pass recorded **138 in one shard**, all re-running deterministic world differences | + +Together that turns a hang from up to 4 × 180s into one 90s wait. A flake missed +by not rerunning is not lost — it fails pass 1, passes pass 2, and is counted as +a fallback. Note that `--reruns 0` as an *argument* would not work: upstream's +conftest overwrites `config.option.reruns` in `pytest_configure`, so clearing +the environment variable is the only lever that holds. + +#### The ones a timeout cannot bound + +That bound is not enough for all of them, and it is worth knowing exactly where +it stops working. Measured on run 34799668707 with the 90s bound already in +place: + +| Group | Isolated pass | Outcome | +| --- | --- | --- | +| `tests/async/` | completed in 296s | the bound works | +| `tests/sync/` | `test_should_work_with_ws_close` printed pytest-timeout's `+++ Timeout +++` banner at exactly 90s | **the process then sat for 1h50m**, until the job's `timeout-minutes` killed it | + +So the signal fires and the *test* dies; the *process* does not. pytest-timeout's +signal method raises at the next bytecode boundary, and Playwright's sync API is +parked in a greenlet switch that never reaches one cleanly — the raise lands +inside the dispatcher and wedges it. `--timeout-method=thread` fires reliably but +kills the interpreter, taking the other ~1500 tests in the group with it. **There +is no per-test timeout value that bounds this.** + +So those modules are **declared, not discovered** — `ISOLATION_HANGS` in +`ci/run_playwright.py`. The isolated pass cannot learn that they hang without +hanging, so it is told: they are `--ignore`d out of pass 1 and run directly in +the main world (pass 1b), where they pass and are counted as fallbacks exactly +as if isolation had failed them honestly. The same tests still run, in the world +that can run them. + +**Why not `ci/skiplist.yml`.** That list means "fails in the most permissive +world", and `ci/run_skiplist_audit.py` enforces it by running every entry with +`CI_WORLD=main` and failing the build on any that **pass**. A `route_web_socket` +test passes there — the main world is precisely where the feature works — so an +entry would be rejected by the audit, and would be untrue as written. The two +lists are not interchangeable, and `test_isolation_hangs_are_not_in_the_skiplist` +keeps them apart. + +Pass 1b sits **above** the `if not failing: continue` guard, deliberately: a +group whose isolated pass found nothing would otherwise skip it, and coverage +would disappear on exactly the runs that look healthiest. + +`tests/patches/isolated-evaluate.py` still owns the direct coverage of isolated +evaluation, and must keep passing regardless. That file is what to check if +isolation itself regresses. + +`ci/run_skiplist_audit.py` deliberately runs in the **main world**: a skiplist +entry has to claim a test cannot pass in *either* world, or the suite would have +counted it as a fallback rather than a failure. + +Ten tests are deselected outright by [`ci/skiplist.yml`](skiplist.yml), which +requires a stated reason per entry — `ci/summarize.py` fails the run on an +unreasoned one. + +**A reason is not evidence, so the reasons are checked.** The first version of +this file inherited all nine `tests/async/*.disabled` modules from the vendored +suite and gave each a plausible justification without running any of them: of +the 202 tests it skipped, **193 passed**, and seven of the nine modules failed +nothing at all. A written reason made them look verified, which is worse than +leaving them bare. + +`ci/run_skiplist_audit.py` now runs every entry with the skiplist disabled and +**fails the build if a skipped test passes**. It is cheap precisely because a +correct skiplist is short — ten tests, a few seconds — and it is what keeps the +list from drifting back into a place failing tests go to disappear. + +```bash +python3 -m ci.run_skiplist_audit --binary /path/to/camoufox-bin +``` + +What remains after the audit, 10 tests: two `test_click.py` tests where +Playwright's stable-position wait races the humanized travel time; six +client-certificate tests (async and sync) that need the **browser** to present a +certificate during the TLS handshake — the two that go through the Node driver's +own request context instead pass, and are not skipped; and the two upstream +expectations that encode a stock-Firefox quirk, replaced by `tests/camoufox/`. + +That client-certificate split is the audit earning its place. The entry was +first written as a whole module, because on a local machine all five fail — +Node/OpenSSL there rejects the fixture server outright. In CI two of them pass, +and the audit failed the build one run after the entry was written. **CI is the +authority for what fails; a local run is a hypothesis.** + +## Camoufox's own suite + +`native-tests/` covers what the Playwright suite cannot ask about: + +- **Leaks.** Launch browsers, kill them, prove nothing survived — file + descriptors, sockets, child processes, X11 lock files. The real assertion is + that cost does not *scale* with launch count, because that is the shape a leak + actually has: a scraper that runs fine for six hours and then dies of EMFILE. + Scope is honest: this measures resources held by our process and its children, + not Gecko's internal heap. +- **Contexts versus browsers.** Two contexts in one browser must get different + fingerprints; two pages in one context must get the same one. Get this wrong + and per-context injection silently degrades to process-global — which passes + every single-context test there is. It has happened here before (commit + `d17c887`, "fix screen size leak in contexts"). +- **Settled decisions.** `ci/tribal-rules.yml` lists choices this project already + made, each with the issue or PR that made it, and + `native-tests/test_tribal_rules.py` asserts them. A comment explaining a + decision only works on someone who reads it. + +## Sundial + +> **On since 2026-09-12.** sundial 0.5.0 is deployed and serving score mode, and +> sundial's master branch now deploys itself on push, so merged does mean +> deployed.

Nothing else leaves +`ci/run_sundial.py::redact()` — not a vector name, description, measured value, +source, and not a per-category breakdown either: a table reading "Graphics 3/17" +is the most useful single fact an adversary could take from a public CI log. + +There are **no per-check rows in the results file at all** — not even opaque +ones. An HMAC does not name a vector, but a map of them still publishes how many +distinct checks fail and lets a reader follow one across releases, which is +per-vector data wearing a hash. The instruction was a score, so it is a score: +regression detection is per-score, via `min_pass_rate` and a maximum allowed +drop. Scope and thresholds live in [`ci/sundial.yml`](sundial.yml); only +categories Camoufox actually claims are gated. + +Everything that leaves `redact()` is checked against a **whitelist** at runtime, +not a blacklist — a blacklist only stops the leaks somebody already thought of. +Adding a field without adding it to `_PUBLISHABLE` fails the run: + +```json +{ "grade": "A", "checks_total": 412, "checks_passed": 403, "pass_rate": 0.978, + "out_of_scope_failed": 6, "cross_os_total": 24, "cross_os_passed": 5, + "os": "linux", "sundial_version": "0.3.1", "schema_version": 1 } +``` + +**Cross-OS detectors are counted, never scored.** They read the host machine +rather than the disguise: a browser claiming macOS while running on Linux fails +them however good its spoofing is, and Camoufox does not claim byte-identical +cross-OS emulation. Folding them into one average would mark it down for a +promise nobody made, and would hide a real regression behind noise it cannot +control. They are reported separately so a drop there reads as "the host shows +through more than it did", which is a different conversation. + +The run asks sundial for `?auto=1&score=1`, so it receives counts and the +vectors never cross the wire at all. + +### Finding out which checks failed + +Worth being precise about, because the answer is "you can't, from CI", and that +is deliberate rather than an oversight. Score mode's payload is buckets keyed +`"|"` holding two integers each. **It carries no check names and +no ids**, so a failing check's identity is not something the CI process discards +— it is something sundial never sends. Nothing in the artifact, the log, or the +sealed report can recover it. + +Two steps down from there, both local only: + +```bash +# which CATEGORY the failures are in -- works with the credential CI already has +python3 -m ci.run_sundial --explain --binary /path/to/camoufox-bin + +# which CHECKS -- needs a role sundial serves full reports to +python3 -m ci.run_sundial --explain --allow-full-report --binary /path/to/camoufox-bin +``` + +`--explain` prints to the terminal and never writes to a result file, and is +**refused outright under `GITHUB_ACTIONS`**: a category-level table is not a +vector, but "Graphics 3/17" is still the most useful single fact an adversary +could take from a public log, which is exactly why `redact()` does not publish +one. + +### Order of operations + +`?score=1` needs a sundial that has it. An older deployment ignores the unknown +parameter and posts the whole report; the numbers still come out right and +`redact()` still discards everything identifying, but **nothing is classified**, +so every cross-OS tally reads `0` — which looks like "no host-OS failures" +rather than "nobody sorted them". `score_mode: false` in the result says which +it is, and the gate says so in its notes rather than leaving you to notice. + +So the dependency runs one way, and setting the GitHub secrets is the *last* +step, not the first: + +1. deploy sundial's score mode — done; it ships in 0.5.0, and master now + deploys on push +2. `gh secret set SUNDIAL_AUTOMATION_KEY -R ` for every repository whose + CI runs this. Without it the job skips, which is the normal case for a fork + pull request +3. flip `enabled: true` in `ci/sundial.yml` — done + +Two things keep a vector out of a public log, and it is worth separating them, +because only one is enforced by the server: + +| | guarantee | +|---|---| +| server-side | The run logs in as `guest`, and sundial's middleware refuses `guest` the private-vector bundle outright — those definitions are never served to the session. | +| client-side | This gate only ever requests `/?auto=1&score=1`, and `redact(require_score_mode=True)` **fails the run** if a full report arrives anyway, rather than folding it down and carrying on. | + +The stricter option is sundial's score-only `ci` role, which is refused anything +but `/?auto=1&score=1` server-side and so cannot be handed a report even if the +credential leaks. That role is not in sundial's master branch and is therefore +not deployed; when it lands, mint the credential (`make pages-ci`, then +redeploy) and set `SUNDIAL_USERNAME=ci`. Nothing in this repository changes — +the client-side half already behaves as though the server were enforcing it. + +There are deliberately **no per-vector rows**, not even opaque ones. An HMAC +names nothing, but a map of them publishes how many distinct checks fail and +lets a reader follow the same id from release to release. + +The cost is real: regression detection drops from per-vector ("the check that +passed last release fails now") to per-score ("we got worse"), covered by +`min_pass_rate` in `ci/sundial.yml` — and, once an auto-update pipeline exists +to compare releases, by a maximum allowed drop in its policy file. To get the per-vector view back for your own debugging, +set `SUNDIAL_REPORT_AGE_RECIPIENT` to an `age` public key — the full report is +then kept encrypted to you and nobody else can open it. + +Needs **`SUNDIAL_AUTOMATION_KEY`** (the password). **`SUNDIAL_USERNAME`** is +optional and names the account, which is not a secret — it defaults to `guest`. +Absent the password — a pull request from a fork — the job is skipped and the +summary says so. + +### What actually stops a vector reaching the log + +Asking for `?score=1` is a promise the caller makes, and a promise is not a +mechanism. Today two things back it: + +- **`guest` cannot load the private vectors, and that is checked.** sundial's + middleware answers `isPrivateVectorAsset` paths with an empty stub for that + role specifically. `admin` and `private` do get them — and `/automated?key=` + resolves to `private` when handed the private key, which is indistinguishable + from the guest one by looking at it. So "we set the right key" stays an + assumption until something checks: the gate reads sundial's own `/__auth/me` + and **refuses to open the browser at all** unless the session is a role the + vectors are withheld from. Not knowing the role counts as not safe. +- **A non-score payload fails the run.** `redact(require_score_mode=True)` + refuses to process a full report rather than folding it down, so a deployment + that ignored `score=1` is a red build, not a quiet leak. + +What is still missing is a server that refuses the *request*. sundial's +score-only `ci` role does exactly that — a bare `/`, `auto=1` without `score=1`, +`?mode=raw`, `?download=true`, `?key=`, the `/automated` and `/locale` export +routes, and any parameter not on its allow-list each get a 403, and on the pages +it does serve the report is never written to a global, so there is nothing for +`page.evaluate`, devtools or a screenshot to read. That role is not merged into +sundial's master and so is not deployed. When it is, set `SUNDIAL_USERNAME=ci`; +nothing here changes, because this side already behaves as though the server +were enforcing it. + +The distinction is worth keeping straight: under `guest`, dropping `score=1` by +accident would put the whole report in the collector and leave `redact()` as the +only thing between it and a public artifact. Under `ci`, the same mistake is a +403 at the first request. `--allow-full-report` exists for a deliberate local +run under an account that is allowed one. + +## Blocking a merge + +Branch protection on `main` requires exactly one check: **`All tests passed`**, +the `gate` job. Pointing at one job instead of a dozen means the required-check +list does not need editing every time a suite is added, renamed, or resharded. + +The gate allows exactly three skips, each for a stated reason: + +| Skipped | Because | +| --- | --- | +| `build` | the browser was fetched, not compiled | +| `fetch-browser` | the browser was compiled, not fetched | +| `sundial` | disabled in `ci/sundial.yml`, or a fork pull request with no stealth credentials | + +Anything else that is not `success` fails it — **including `skipped`**. A suite +that did not run has not passed, and quietly skipping one is the cheapest route +to a green tick. + +`build` is also the one suite dropped from `--require` when the browser was +fetched rather than compiled: that job writes no result, and requiring a name +nothing produces fails a run where everything passed. + +One suite may additionally record a **`skip` result** without failing the run, +named explicitly in `--allow-skip`: `sundial`, and only when sundial itself is +unreachable. It is a separate service on a separate host, so an outage there +means this browser was never measured — neither a pass nor a failure is true, +and blocking every merge in the repository on someone else's downtime is the +wrong answer. The summary shows it as skipped with the reason. A rejected +credential, a role that would be served the private vectors, a full report where +a score was requested, or a score under the floor all still fail: those are +answers, and an answer gets judged. + +The settings live in [`ci/branch-protection.json`](branch-protection.json) so +they are reviewable rather than lore. To apply them (needs admin): + +```bash +gh api -X PUT repos///branches/main/protection \ + --input ci/branch-protection.json +``` + +Two choices worth knowing about: + +- **`enforce_admins: false`** — you can still merge when CI itself is broken. + Protection should stop mistakes, not lock you out of your own repository. +- **`strict: false`** — a pull request does not have to be rebased onto the + latest `main` before merging. With `true`, every push to `main` would + invalidate every open pull request and force another build, and a build here + is over an hour cold. + +Reviews are deliberately not required: a solo maintainer cannot approve their +own pull request, so requiring one would block every merge. + +## Cost control + +Each tier gates the next, so a two-second lint failure never reaches the build: + +``` +0 static lint, self-tests, settled decisions seconds +1 unit pythonlib ~1 min +2 browser build (patches/additions/settings/assets/upstream.sh/Makefile/scripts changed) + fetch (anything else -- driver changes test against the published release) +3a smoke patch guards, build-tester ~15 min +3b full Playwright x2, leaks, stealth ~40 min +4 gate the required check +``` + +**Driver-only pull requests never build.** There is nothing new to compile, so +`fetch-browser` downloads the published release and the browser suites run +against the build users are actually on — a minute instead of seventy. + +**Changing Juggler's JavaScript does not rebuild the browser.** Measured on a +real build: ccache reported a **98.63%** hit rate, so almost none of those 24 +minutes was compiling C++ — it was Rust, linking libxul, and packaging, none of +which a `.js` file affects. And in the *unpackaged* `dist/bin` that CI archives +there is no `omni.ja` at all: Juggler is loose files under `chrome/juggler/`, so +delivering new JavaScript is a file copy. + +So the build cache is keyed on a hash of the **compiled** inputs only +(`ci/browser_inputs.py`). If that hash matches, the compiled half is identical +*by construction* — no diff required, and no dependence on what the pull request +base happened to contain — and this branch's resources are laid over the +restored browser. A Juggler JavaScript change costs about a minute instead of +twenty-four. + +Two things make that dangerous, and both are closed and mutation-tested: + +| Trap | What closes it | +| --- | --- | +| `additions/juggler/` is **not** all JavaScript — it holds the screencast encoder and the debugging pipe (5 `.cpp`, 5 `.h`, 2 `.idl`, 3 `components.conf`, 4 `moz.build`) | Only files `jar.mn` actually lists are resources. Everything else — including any extension nobody has considered yet — is native and forces a build. `jar.mn` itself is native, so removing an entry cannot leave a stale file behind | +| The source→destination mapping is **per-file, not a prefix** | It is read from `jar.mn`. `TargetRegistry.js` → `content/TargetRegistry.js` (a level added), `content/FrameTree.js` → `content/content/FrameTree.js` (preserved), `content/JugglerFrameChild.sys.mjs` → `content/JugglerFrameChild.sys.mjs` (dropped). Two files in one source directory landing at different depths is exactly what a prefix rule gets wrong — and it would run stale Juggler while every suite went green | + +**A browser that is already built is not built again.** `browser_changed` is +computed against the pull request's *base*, so it stays true for every push to a +branch that touched `patches/` even once. That is right — the published release +does not contain that branch's browser changes, so it cannot be tested against — +but taken alone it meant recompiling a byte-identical browser on every push, 24 +minutes at a time, to fix a typo in `ci/`. + +The build job therefore asks a narrower question first: not "does this branch +change the browser" but "has the browser changed since the last one we built". +The answer is a cache keyed on a hash of every input that can alter the binary — +the same path list `browser_changed` uses, plus this workflow, which pins the +toolchain. On a hit, a 634 MB `camoufox-dist.tar.zst` is restored and every +build step is skipped; the run still records a `build` result saying the browser +was restored rather than compiled, because a required suite that reports nothing +fails the gate, and "nothing was compiled" should be a fact in the evidence +rather than a hole in it. + +Deliberately **no `restore-keys`** on that cache. Everywhere else a partial +match is fine — a partly warm ccache is still warm — but here it would hand the +test jobs a browser built from different sources, and every suite would report +on it looking perfectly healthy. A self-test asserts the key covers every path +`browser_changed` considers browser-affecting, so the two cannot drift apart. + +**The ccache is kept warm from `main`.** Pushes to `main` populate it and a +twice-weekly schedule keeps it from being evicted (GitHub drops a cache after +seven days unused). Pull requests restore it through `restore-keys`, so a build +in a pull request starts warm even though its own key is new. + +A prebuilt image in `ghcr.io` with the object cache baked in would be warmer +still and would not need the eviction guard. It also needs registry credentials +and a rebuild pipeline of its own; this is the version that works with no setup. + +**Preparing the tree retries the network, and nothing else.** `mach bootstrap` +pulls toolchains from Taskcluster, and a connection reset there used to fail the +whole pull request. `ci.run_prepare` runs `setup-minimal` → `dir` → +`mozbootstrap`, retrying the two that download things and only when the failure +text reads as transient. A failed patch hunk or a compile error still fails on +the first attempt — retrying a broken tree only spends a runner to reach the +same answer, and a retry loop that swallows a real breakage turns a red build +into a slow red build. + +> One consequence of `cancel-in-progress`: pushing to a branch cancels its +> running build.
