From 005f8a3aca8e9650d6dbc81f746470f207658e88 Mon Sep 17 00:00:00 2001 From: Jason Ross Date: Sat, 4 Jul 2026 02:18:10 -0500 Subject: [PATCH 01/19] fix(reporting): scrub PII from crash stack traces + move ReportStore scan off the main thread MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A crash report captured throwable.stackTraceToString() verbatim, so mail/network exceptions (Jakarta Mail, java.net) could embed server host:port tokens and account emails/usernames in the report's stackTrace field — violating the PII-free-reports constraint. Add StackTraceScrubber, applied in DiagnosticsCollector before the trace enters toSubmissionPayload()/toStorageJson(): it keeps the non-PII value (exception class names + every frame's class/method/file/line) and drops each header line's free-text message (where hostnames/usernames live), then redacts any residual email or host:port left on a wrapped continuation line. Frame lines are untouched, so a frame's File.kt:42 is never mistaken for a host:port. ReportStore did MutableStateFlow(scan()) in its constructor — a dir list + read + JSON-parse of every stored report. As an eager @Singleton dep of CrashReporter, whose install() runs on the MAIN thread in Application.onCreate(), this was main-thread disk I/O that grows with the 30-day retention. Seed the flow empty and dispatch the initial scan to an injectable scope (Dispatchers.IO by default); reactive consumers update when it lands, and writes still re-scan synchronously so a crash-time save is never lost. Tests: StackTraceScrubberTest (host/ip/port/email dropped from a ConnectException + auth-failure trace while classes/frames survive; regex redaction of a continuation line; null-message trace preserved verbatim); DiagnosticsCollector end-to-end scrub test; ReportStore empty-seed + off-thread populate via a StandardTestDispatcher. Store constructions in existing tests use an Unconfined scope to keep their synchronous reopen semantics.

From: Jason Ross Date: Sat, 4 Jul 2026 02:30:50 -0500 Subject: [PATCH 02/19] perf/fix(data): batch sync updates, paging tiebreaker, migration-registration test #310: add a single-transaction MessageDao.updateHeaderContents(List) and route MailSyncer's per-message updateHeaderContent loop through it, so a folder's recent-window refresh commits once instead of once per message (fsync/journal write per message, amplified on the encrypted cache). #311: append the `id` primary key as a tiebreaker to the four paged MessageDao `ORDER BY timestampMillis DESC` queries for a total order, so rows sharing a second (bulk mail) can't duplicate or skip across a LIMIT/OFFSET page boundary. Pure query-text change: the exported Room schema (identityHash) is derived from table/index structure, not @Query SQL, so no schema re-export or version bump; id is already in the projection, so no new index. #312: expose the registered migration list as DatabaseModule.ALL_MIGRATIONS (spread into addMigrations) and assert in MigrationTest that it equals the reflectively-discovered set of every Migration val, so a migration forgotten in addMigrations fails a test instead of crash-looping all upgrading users at DB open (there is deliberately no destructive fallback). Tests: new MessageDaoTest cases for the batch update and the id tiebreaker (all four pagers), and the MigrationTest registration assertion; wired updateHeaderContents into MailSyncConcurrencyTest's fake DAO.

Corrects PR #292, which excluded **/*Worker*: SyncWorker, BackfillWorker, PruneWorker, SendWorker, ReportPurgeWorker and ReportUploadWorker are all directly unit-tested, so they stay counted in both numerator and denominator (only their Hilt wiring, WorkManagerModule, is excluded, via **/di/**).

Exit codes 0/2/3/4 preserved. - Cross-platform process kill abstracted per-OS: taskkill /F /IM on Windows, pkill -f qemu-system on *nix; process listing via tasklist / ps ax. - Teardown hardened vs the .sh: it now also reaps the emulator *launcher* image, not just qemu -- the Windows -no-window emulator spawns a sibling emulator.exe that briefly outlives the qemu VM, which a qemu-only sweep left as an orphan on return (caught by the smoke run). - SKILL.md + CLAUDE.md: replace the local api35/api36 GMD E2E steps with local_instrumented.py; CI's own multi-API matrix is untouched. CLAUDE.md documents the Python-first dev-script convention. Validated: py_compile, argparse (--help / no-arg exit 2), and a guarded emulator smoke run of org.libremail.data.local.DatabaseEncryptionTest -- boots, passes, and tears down clean (no qemu/emulator orphan on return).

We reuse a GMD-provisioned AVD by name so we don't re-download a system + image; GMD re-provisions its own copy on its next run, so the ``-wipe-data`` cold boot + here does not disturb it. + +KEEP RUNS TARGETED -- THE ~114-TEST MID-SUITE WEDGE +--------------------------------------------------- +Running the WHOLE instrumented suite (~114 tests) via ``connectedDebugAndroidTest`` on this +box tends to wedge partway through -- the emulator stops making progress mid-run.

That is why this helper takes an explicit +``[,...]`` argument and filters the run with +``-Pandroid.testInstrumentationRunnerArguments.class=...`` instead of running everything. +Run the class(es) you actually changed; do not use this to run the full suite (that is +CI's / preflight's job across the API matrix). + +FREEZE / HYGIENE RATIONALE -- WHY THE ORPHAN-KILL + TEARDOWN VERIFY ARE MANDATORY +-------------------------------------------------------------------------------- +A hung ``adb emu kill`` (or an interrupted run) leaves a detached qemu VM process behind +(``qemu-system-x86_64-headless.exe`` on Windows; a ``qemu-system-*`` process on *nix). +These orphans do not show up in ``adb devices``, they keep holding the hypervisor + RAM, +and accumulated orphans have FROZEN this machine outright. So this script: + * PREAMBLE -- force-kills any pre-existing qemu/emulator processes and resets the adb + server BEFORE booting, so we always start from a clean slate. + * TEARDOWN -- ``adb emu kill``, kill the launcher we spawned, then re-check for ANY + surviving emulator/qemu process and force-kill it (the ``-no-window`` emulator + can leave a sibling ``emulator.exe`` that briefly outlives the qemu VM). Teardown + runs even on Ctrl-C / error / SIGTERM (try/finally + atexit + SIGINT/SIGTERM + handlers) and is idempotent. + * VERIFY -- if a qemu process is STILL alive after the force-kill, the script exits + non-zero (code 3) so the leak is never silently ignored. +Never leave an emulator running after this script; if it exits 3, hunt the zombie down by +hand (Windows: ``tasklist | findstr qemu`` then ``taskkill /F /IM +qemu-system-x86_64-headless.exe``; *nix: ``pgrep -fa qemu-system`` then ``pkill -f +qemu-system``). + +CROSS-PLATFORM PROCESS KILL +--------------------------- +Listing and force-killing the emulator/qemu processes is abstracted per-OS (see +``list_procs`` / ``force_kill``): Windows uses ``tasklist`` + ``taskkill /F /IM ``; +*nix uses ``ps ax`` + ``pkill -f qemu-system`` (alongside the graceful ``adb emu kill``). +The qemu VM is the freeze-causing orphan on every platform. + +EXIT CODES (preserved from local_instrumented.sh) + 0 tests passed + 2 usage / precondition failure + 3 a qemu zombie survived teardown -- clean it up by hand before the next run + 4 emulator never reached sys.boot_completed + connectedDebugAndroidTest's own non-zero exit code (test failures) + +REQUIREMENTS + * Android SDK ``emulator`` + ``adb`` on PATH. + * A JDK 17-21 for the Gradle daemon -- AGP 9.2 fails on JDK 25+.

The existing no-throwable overloads are unchanged. Add accountLogRef(accountId): a short, stable, non-reversible reference (scheme prefix + truncated SHA-256 of the id) so downstream logging can identify an account without logging the raw Account.id, which embeds the email.

RestartActivity runs in the separate :restart trampoline process, where LibreMailApplication.onCreate returns early and never calls AppLog.install, so this breadcrumb reaches Logcat only, never a DebugReport. The migration is guard-compliance + Logcat-consistency only; behavior is unchanged since AppLog forwards to Logcat. RestartActivity is DEVICE-ONLY (multi-process kill/relaunch), so a JVM buffer-capture test doesn't apply here. Added RestartActivityLoggingTest, which instead pins the null-buffer shape this call runs under in the trampoline process: it forwards to Logcat and no-ops the buffer cleanly.

Add rich boot diagnostics by default, kept in parity between CI and the local hand-provisioning script (api37_e2e.py): - Launch the emulator with `-verbose -debug init,avd_config,kernel` (diagnostics only; no boot-affecting flag changed), still redirecting to $EMU_LOG. - Stream `adb logcat -v time` to a file from the moment the device registers (via `adb wait-for-device logcat`, backgrounded). - On a boot timeout, dump accel-check, /dev/kvm presence, GPU mode, free mem/disk, the AVD config.ini and the emulator.log tail; CI writes these to a boot-diagnostics file, the local script prints them. - CI uploads emulator.log + logcat.txt + boot-diagnostics.txt as an artifact with `if: always()` so they survive a timeout/cancel, and prints a concise summary (accel/KVM status + last 50 lines of emulator.log) to the step log. The existing 2-attempt boot retry + boot-completed wait loop are unchanged; the diagnostics are additive.

No PII or key material is logged; table-name sets and boolean flags only. Adds instrumented tests (DatabaseKeyCipher is device-only and behavior-preserving, so no new test there) asserting the breadcrumbs land in a RingLogBuffer and never contain the seeded email, secret, or passphrase.

Also closes #297: SendWorker and IdleService logged the raw account.email via Log.w on the Graph->SMTP fallback and IDLE-drop paths. Both now log accountLogRef(account.id) instead -- a short, stable, non-reversible per-account reference -- so the account's email never reaches Logcat or a report. Rewrites ImapClientTest/SendWorkerTest to install a real RingLogBuffer via AppLog.install(...) and assert on its contents (migrated calls + new breadcrumbs), instead of verifying a mocked Log; every assertion also checks no line carries the test account's email, regression-covering #297. Adds a SendWorkerTest case that drives a real SmtpSender against an in-process GreenMail SMTP server end to end. android.util.Log is still stubbed (by fully-qualified name, without importing it) where AppLog's Logcat passthrough would otherwise crash the unmocked Android stub in a JVM test.

charset=UTF-8 Content-Transfer-Encoding: 8bit Migrate AppLockViewModel (9 sites) and AccountSetupViewModel (1 site) off raw android.util.Log onto the AppLog seam (#325), so their diagnostic lines land in the RingLogBuffer and reach a submitted DebugReport instead of only Logcat. Adds three new breadcrumbs that were previously silent: auth-seal unlock success, the clear-cache-and-restart recovery trigger (with the disableAppLock flag), and every onForeground LockAction decision. AccountSetupViewModel's success path also now logs "Outlook account added" (no email). None of these call sites carry PII; where a throwable is attached, AppLog's StackTraceScrubber redacts it before it reaches the buffer. Both ViewModel test suites now install a real RingLogBuffer and assert against it instead of `verify { Log... }`, including dedicated no-PII assertions (a known test email never appears in a recorded line). A minimal `mockkStatic(Log::class)` stub stays in both test files' shared setUp — AppLog still forwards to the real android.util.Log internally, which throws "not mocked" in JVM unit tests when uninvoked; the not-yet -landed guard-rule ticket (#331) will need to reconcile that with a repo-wide "no raw Log outside AppLog.kt" rule.

Add net-new AppLog breadcrumbs at each class's lifecycle points per the #324 strangler-migration plan: sync start/done/failed and per-folder fetch counts, backfill slice start/done and per-folder page counts, prune's removed count, and each worker's cache-locked deferral and success/retry outcome (the retry path now also carries the scrubbed failure throwable via AppLog's #325 overloads). Every breadcrumb is PII-safe by construction: accounts are identified only via accountLogRef(account.id) (never the id or email directly), and a new logSafeFolderLabel() helper logs a folder's name only when it matches a fixed allowlist of known system folders (INBOX, Sent, Drafts, Trash, Spam/Junk, Archive, and their common provider variants) — every other folder, however nested or named, logs as a fixed placeholder. Adding logging to these previously-silent classes meant every existing test exercising them now hits android.util.Log (a throwing stub under plain JVM unit tests), so each affected suite gains the same static Log mock already established by AppLogTest/SendWorkerTest/ImapClientTest.

A PR +that gets cancelled this way isn't harmed long-term — it simply reruns on its next push, +or the next time `autoupdate.yml` rebases it onto `main`. Because nothing outranks an +emergency, a `P0` PR also never does the hold-back wait described below. + +### A `broken` PR can be preempted by anyone + +A PR labelled `broken` can't merge while it's broken, so its CI run occupying a runner +is wasted capacity. Any PR that isn't itself `broken` — in other words, any PR with a +real `P0`–`P9` priority — outranks it and may cancel its active run to reclaim the +runner, not just a `P0` PR. `broken` is also the only priority level that yields to +*everything*: since it sits below every other level, it always waits for other PRs' +runs rather than the other way around. + +### P1–P9 yield, but never cancel + +Every other level (`P1`–`P9`, including the `P5` default) is cooperative rather than +aggressive: it never cancels a run that's already going, no matter how much lower that +run's priority is. Instead, before letting its own heavy jobs start, it checks whether +any **strictly higher**-priority PR currently has an active or queued CI run. If so, it +waits — polling every 15 seconds and re-checking the full list of open PRs each time, so +a newly opened higher-priority PR is picked up mid-wait too — giving that PR's jobs a +chance to reach the runner queue first. The wait is capped at **180 seconds** +(comfortably inside the job's 6-minute hard timeout); once the budget runs out, this PR +proceeds regardless. A PR should never be able to block itself indefinitely. + +## Safety invariants + +Whatever the priority math says, a few things are hard-coded to never happen: + +- **Never touches `main` / push-triggered runs.** The job only acts on `pull_request` + events, and every run it's even allowed to consider cancelling is filtered down to + `event == pull_request` with `headBranch != main`. +- **Never cancels this PR's own run.** The current PR is excluded from the "other PRs" + list up front by PR number, and the currently-executing run ID is skipped too, just in + case. +- **Never cancels an equal-or-higher-priority run.** Only strictly-lower-priority PRs + (a numerically larger, i.e. worse, priority) are ever candidates for cancellation. + +## Honest limitation + +This is a **best-effort head start, not a real priority queue.** GitHub Actions has no +API for "give this run's jobs priority over that run's jobs" — runners are handed out +roughly FIFO no matter what this job does. Hold-back approximates priority by making +lower-priority PRs wait a little before their jobs even enter that FIFO queue, but under +sustained contention (many PRs queuing at once) the bounded wait can run out before a +higher-priority PR's jobs have actually made it through the runner pool. The waiting job +itself is cheap and short-lived, which is exactly why the wait is capped rather than +open-ended — occasionally under-prioritizing is preferable to a job that ties up a +runner indefinitely just to wait. + +## Not a merge gate + +`traffic-control` is an optimizer, not a check your PR needs to pass. It's deliberately +left out of `ci-passed`'s `needs:` list, every GitHub API call it makes is guarded +against failure, the script always exits `0`, and the step itself runs with +`continue-on-error: true`. A hiccup here — a transient API error, a missing permission, +a fork PR without write access — can never fail or block your PR. + +That said, the heavy jobs still order themselves after it via `needs: traffic-control`, +so if this job were ever skipped or failed outright, GitHub would mark those jobs +`skipped` — and `ci-passed` treats a required job coming back `skipped` as a gate +failure. So the worst case is fail-safe: it blocks the merge rather than letting an +untested PR through. + +It also needs very little to run: no checkout step (it only calls the `gh` CLI), and +just two permissions (`actions: write` to cancel runs, `pull-requests: read` to read +labels). Values that come from outside the repo — labels, branch names — are only ever +read through `gh`'s JSON output into shell variables, never interpolated as shell code. + +## Where this is heading + +**#342** is rewriting this logic as a tested Python module +(`.github/scripts/traffic_control.py`), with a couple of small behavior refinements: +draft PRs will also sink to the bottom (like `broken`), and PRs at the exact same +priority level get an explicit order (whichever run is already in flight finishes +first; among the rest, whoever has been waiting longest goes next). This README +describes the shell-script version currently in `ci.yml` — see the comment block above +the `traffic-control` job there for the byte-for-byte spec — and will be updated once +#342 lands. From 8b7f895d6afb7cc5b5306f5d10c6501045d783ef Mon Sep 17 00:00:00 2001 From: Jason Ross Date: Sat, 4 Jul 2026 22:08:13 -0500 Subject: [PATCH 15/19] ci: extract traffic-controller into a testable Python module (#342) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The priority-based runner orchestration ("traffic-control") lived as a large inline-bash step in ci.yml — a two-pass preemption + hold-back script that was effectively untestable in YAML. Move it into .github/scripts/traffic_control.py, structured as a pure decision CORE + a thin gh-I/O SHELL: * Pure functions (no network/clock/subprocess), unit-testable in isolation: - effective_priority(pr): lowest-numbered P0-P9, default P5; broken OR draft => 10. - runs_to_cancel(this_pr, all_prs, self_run_id): PASS 1 — run ids to cancel, empty unless THIS PR is P0; only strictly-lower running/queued runs; never self (by number or run id), never equal-or-higher. - wait_blockers(this_pr, all_prs): PASS 2 — yield to any strictly-higher PR with an active/queued run, and to same-level peers ordered ahead (running-first, then oldest createdAt). Empty => proceed. * Shell (run_live): gathers the snapshot via gh, applies cancels, runs the bounded hold-back poll loop; always exits 0. --dry-run feeds the core a snapshot JSON and prints decisions with zero network. * No jq/bash dependency (cross-platform, per the repo's Python-stdlib convention). ci.yml's traffic-control job now checks out the repo and runs the module. Job permissions gain `contents: read` (for checkout) alongside the existing `actions: write` / `pull-requests: read`; env and downstream `needs:` wiring unchanged; step stays `continue-on-error`. 33 stdlib unittest cases cover priority resolution, P0-only preemption, the self/main/equal-or-higher invariants, and the same-level running-first/oldest ordering. Behaviour is preserved except the ticket's refinements: (1) drafts now count as P10 (bottom); (2) an explicit same-level running-first-then-oldest tiebreaker; and (3) per the ticket's order-of-operations, ONLY P0 preempts — the old bash also let any higher-priority PR cancel a `broken` target's run, which no longer happens (a broken/draft run is only cancelled by a P0, via the same strictly-lower rule).

P1-P9 still never bump a *normal* (non-broken/draft) lower run; a broken/draft PR (P10) preempts nothing (nothing is strictly-lower than the bottom, and the equal-or-higher invariant means a P10 never cancels another P10). Self / main-push / equal-or-higher invariants unchanged. Updates the module docstring + ci.yml comments (the "only P0 preempts" wording becomes: P0 preempts everything strictly-lower; additionally, any strictly-higher PR preempts a broken/draft run) and the job step/permission/needs comments. Adds unit tests: P3 reclaims a broken P10 run and a draft P10 run; P3 does not bump a normal P5 run; a P10 self preempts nothing; plus an end-to-end P5-reclaims-draft-then-waits scenario. 37 unit tests pass; ci.yml parses clean; --dry-run shows a P3 cancelling a draft (and broken) run while still yielding to a higher P1.

It runs after autoupdate finishes (workflow_run, race-free) plus a cron backstop plus manual dispatch. - Triggering uses workflow_dispatch, which is EXEMPT from anti-recursion, so the built-in GITHUB_TOKEN (actions: write) starts the run — NO PAT / secret change needed. - ci.yml gains a workflow_dispatch trigger (pr/head_sha/reason inputs) and a per-PR concurrency group unifying pull_request and dispatch runs; its on: pull_request path is kept so brand-new PRs, human pushes, and fork PRs always get CI (fail-open). Pure select_triggers / classify_sha_runs decision core added to traffic_control.py with 24 new unit tests (priority order, oldest-first fairness, inflight cap, fork skip, P0 bypass+preempt, head-SHA needy classification, and a liveness/anti-starvation simulation).
