From 72af29e89fb10ec8f43ae412fabbee5b24cfaad8 Mon Sep 17 00:00:00 2001 From: Lukas Wuttke Date: Tue, 18 Aug 2026 10:01:21 +0200 Subject: [PATCH 01/11] feat(telemetry): one outcome event per install, with nowhere to put a path (backend#1907) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The installer is the highest-variance, least-observed step in the product: it runs on machines we have never seen, under package managers, proxies and shells we do not control, and it reports to nobody. Each of the backend#736 failures — the CLI landing in ~/.local/bin with PATH advice only printed, apt-get appearing hung because unattended-upgrades held the dpkg lock — was invisible until a customer happened to mention it. scripts/lib/telemetry.sh emits one contract-shaped event per run from install_cleanup, the EXIT trap, so it fires on every path including the interrupted and the fatal one. It carries the phase reached, per-phase durations, the exit code, the client state, OS/arch, the version, an error class, and — for the #736 PATH case specifically — TB_CLI_ON_FRESH_PATH, which install-cli.sh has always computed and only ever printed advice about. "NO ARGUMENTS, NO PATHS, NO DATA" IS A SHAPE, NOT A RULE. Every value goes through _telemetry_attr, which admits a string only if it matches ^[A-Za-z0-9._-]{1,64}$ and an integer only if it is one. A path contains '/', a proxy credential contains ':' and '@', a token is longer than 64 characters, a name contains a space. Values that fail are dropped, never trimmed: a redactor has to imagine what it is stripping, and a shape only admits what it was told to. The phase and the client state are additionally checked against their closed sets at the render boundary — a canary assigned straight to TB_TELEMETRY_PHASE reached the record before that line existed, and it was shaped exactly like a legal value, so the token regex waved it through. The vocabularies are DERIVED, and a new guard proves it. scripts/tests/telemetry-vocabulary-agreement.sh parses install-k8s.sh's step_header calls, summary.sh's CLIENT_STATE writers, gen-manifest.sh's FILES array and install.sh's release-tag regex, and compares each to telemetry.sh's declaration; the error classes have no second declaration, so it exercises the classifier over the full cross-product and checks both that every answer is registered and that every registered class is reachable. It runs in drift-checks' `Source-of-truth drift` job, which is required — a guard in a job nobody must wait for is advice. It found one thing on its first run: summary.sh's own CLIENT_STATE docstring had been missing image_pull_ca since #424. TWO REAL BUGS THE TESTS CAUGHT, both of the same shape and both fatal: `printf | grep -q` returns 141 on a match under `set -o pipefail`, and so does `tr -dc < /dev/urandom | head -c 16` — the latter at SOURCE time, which killed the whole installer before it printed a line. Every unit-level test passed throughout; only the test that runs install_cleanup for real under the installer's own shell options went red. That test stays. install-bootstrap.bats held a hand-written second copy of install.sh's FILES array, in two places, so adding a lib turned ten unrelated supply-chain tests red. It now derives the list, and fails closed on an inert parse. WHAT IS NOT CONNECTED: the transport. The 17 Aug decision (rfcs#28) replaced the Collector gateway with an ingest endpoint on the backend — backend#1905, which does not exist yet — so _telemetry_deliver writes the install log and a bounded 0600 local spool that #1906's forwarder can drain, and posts nothing. Opt-out (default on) via TRACEBLOC_NO_TELEMETRY or DO_NOT_TRACK, documented in --help — and that promise is itself checked, because a user who exports a stale name believes they have opted out.

The fixture's purpose is unchanged — TB_ERR_CMD holds the failing command UNEXPANDED, which is free text carrying a path, and must not be emitted. It now carries a path instead of a credential.

Reproduced: $ HOST_DATA_DIR=$T bash scripts/install-k8s.sh --help {"attributes":{"event.name":"install.run.succeeded", "tracebloc.install.phase":"bootstrap","tracebloc.install.exit_code":0,…}} That is the worst bug this feature could have. `--help` is the command people run MOST while a real install is broken, so a free success lands in the denominator of the failure RATE — the one number the ticket exists to produce — and moves it in the direction that hides the problem. Found by Bugbot on client#747. The fix is a latch, not a phase test: main() calls telemetry_run_started once --help / --diagnose / prepare-host have had their chance to dispatch, and telemetry_emit_outcome returns early without it. A phase test would have been wrong — a genuine failure IN the bootstrap phase (the leftover-data guard, validate_config) is an install attempt and must still be reported, which is now pinned by a test that drives the real entrypoint into a validate_config rejection. Found while fixing it: the assess handoff exits 0 having run no step, so counting it as succeeded would grow the success count with re-runs on machines nothing happened to. It now emits install.run.skipped — a registered outcome verb (contract §6.4), so no new vocabulary — which also makes "how often is the installer re-run on a machine that was already done" answerable. prepare-host is deliberately still not reported: it is a different command with its own registry component (§10.1), and filing it under tracebloc.component=install would be mislabelling it rather than measuring it. TWO OF THE SIX NEW MUTATIONS CAME BACK INERT on the first pass — "main stops setting the latch" and "assess.sh stops marking the handoff" — because the tests set those flags themselves and so could not see the WIRING disappear. That is the same class as the bug Bugbot found: a unit test of the emitter cannot observe which exits reach the trap. Both are now driven end to end, through the real install-k8s.sh and the real _assess_handoff, and both mutations redden. Bugbot's second finding (the source lookup aborting the whole event under set -e) is reported as unreachable with evidence rather than fixed: a command substitution in an ARGUMENT position does not propagate its status to the enclosing command, measured on bash 3.2.57 and 5.x. The invariant is pinned anyway — an unrecognised source location drops the field, never the event.

That lost the most important number in the file, and it lost it in exactly the case the ticket names: * on every SUCCESSFUL install, phase_connect_ms was absent — the readiness wait, up to READY_TIMEOUT (600s), the single longest phase; * on every failure and every cancel, the phase named by tracebloc.install.phase had no duration. The dpkg-lock case in its likeliest real form is stuck twenty minutes in `prerequisites` and then killed or given up on, never reaching step c. Reproduced before fixing: "tracebloc.install.phase":"prerequisites" "tracebloc.install.phase_preflight_ms":0 * `bootstrap` had no key at all, because the loop iterated the letter map and bootstrap has no step letter. So the download + verify + leftover-guard + assess time was an unnamed remainder — which is also why subtracting the other keys from duration_ms could not recover the missing active phase. Found by Bugbot on client#747. My own "a slow phase is visible" test passed throughout, because it only ever measured a phase a later step_header had closed — the exact shape of a test that proves the easy half. The live delta is added at READ time rather than by a "close the phase" call in the emit path, so render stays idempotent: the tests call it repeatedly, and a render that mutated the accumulators would report different numbers each time. The clock is now read once per event, so the per-phase numbers and the total are exactly consistent — which is an invariant a test asserts. That test needed a FAKE CLOCK. The obvious fixture is wrong: winding _TB_TELEMETRY_PHASE_STARTED_MS backwards after the step_headers have already attributed that time invents milliseconds that never elapsed, and the first version failed for precisely that reason (sum 1200000 vs total 900000). Four mutations run. Three redden — dropping the live delta, going back to the letter map, and counting the delta for every phase. The fourth (reading the clock per attribute instead of once) is INERT and is reported as inert rather than counted: _telemetry_now_ms has second resolution, so two reads inside the same second are identical, and the guard only matters across a second boundary.

That guard deliberately skips an existing directory ("an EXISTING data dir has no at-risk mkdir here", client#441), so anything creating the directory behind its back disarms it for every later run: run 1: guard refuses (dir absent) -> error -> EXIT trap -> telemetry creates it run 2: guard sees the dir, returns 0 -> MySQL installs onto NFS which is exactly the InnoDB corruption client#432 exists to prevent, reintroduced by the telemetry that was only supposed to watch. Reproduced before fixing: guard exit=1 HOST_DATA_DIR created on the REJECTED volume? YES ./nfs-volume/.tracebloc/telemetry An observer that changes the install's own preconditions is not an observer. The spool now only writes INTO a data dir that already exists; a run that dies before that still reports through the install log, which is what a support bundle collects and which _choose_log_file has already placed somewhere safe (falling back to $TMPDIR). Found by Bugbot on client#747 — the third real finding of three rounds, and the most serious: the other two corrupted the metric, this one corrupted a customer's database. Both directions mutation-proven: removing the existence check reddens the new test, and disabling delivery outright reddens four others, so the fix cannot pass by simply turning the feature off.

It does not. `log` is a no-op until setup_log_file sets LOG_FILE, and setup_log_file runs AFTER validate_config and early_data_dir_guard — deliberately, because #432 refuses a network data dir BEFORE logging starts. So on exactly those paths there was no log AND (correctly, since the previous commit) no data dir, and the rendered event was discarded: $ early_data_dir_guard # target reads as nfs guard exit=1 any telemetry written anywhere? 0 A run refused for being on NFS is a real, actionable field failure, and it was the single case producing no record at all — invisible to the very failure rate this feature exists to produce. Those pre-log failures are also precisely the class the run-started latch was built to preserve, so losing them undid that too. Found by Bugbot on client#747, which also spotted that this file's own NFS test masked the bug by setting LOG_FILE=/dev/null. That test now leaves LOG_FILE unset, as the real path does, and asserts the refusal IS reported. Fix: when there is no data dir, spool to a mktemp'd file in $TMPDIR. mktemp and not a fixed name — /tmp is world-writable on Linux and the installer runs privileged steps, so a predictable path is a symlink target for an append that may be running under sudo; mktemp creates with O_EXCL. This mirrors _choose_log_file's own fallback, so an early-failure run leaves one small file beside the install log it already leaves there, rather than a new class of litter. #1906's forwarder reads both locations. A comment that claims something untrue is itself the defect (workspace CLAUDE.md rule 7), so the false claim is replaced with what actually holds and why. Four mutations, all reddening: removing the fallback, giving it a predictable shared path, dropping its 0600 mode, and dropping the data-dir existence test (which would disarm the NFS guard again).

The first one is the significant one: it silently undid round 4 on the primary macOS path. 1. The fallback spool landed inside the bootstrap's own scratch dir. install.sh:238 does `TMPDIR="$(mktemp -d)"` and :239 traps `rm -rf "$TMPDIR"`. A plain assignment to a name that is ALREADY EXPORTED keeps the export attribute — and TMPDIR is always exported on macOS — so install-k8s.sh inherited the doomed directory and `mktemp "${TMPDIR:-/tmp}/…"` wrote the record into it. Reproduced end-to-end: the spooled file was gone the moment the bootstrap returned. So the NFS refusal, and every other pre-setup_log_file failure, still produced no record anywhere on macOS — the exact hole the fallback closed. _telemetry_fallback_dir now disqualifies TMPDIR when the running installer is inside it, which is true precisely when TMPDIR is the bootstrap's scratch dir, and falls back to $HOME (never $HOME/.tracebloc — telemetry must not create HOST_DATA_DIR) and then /tmp. DERIVED rather than agreed: asking install.sh to export its original TMPDIR under another name would work only when the bootstrap is new, and install.sh is served from a URL a user may have curl'd months ago. Both sides of that comparison are resolved with `pwd -P`. The first cut compared them as written and missed every Mac, because /var is a symlink to /private/var — caught by re-running the reproduction against the fix, not by reading it. 2. grep is line-based, so a value with a newline passed the shape check. The one input shape "nowhere for a path to go" does not cover, because what lands is not a path — it is a second line: TB_VERSION=$'v1.9.3\n","tracebloc.install.injected":"yes' → "service.version":"v1.9.3 ","tracebloc.install.injected":"yes",… A forged attribute AND one record split across two lines of a .jsonl spool, so #1906's forwarder reads two malformed events. Reproduced on all four checks — the key, str and int shapes in _telemetry_attr, _telemetry_version, and _telemetry_source_line's inline regex. All now `[[ =~ ]]`, which anchors at end of string. As a bonus it removes the external process, so the backend#1778 SIGPIPE class the here-strings were working around cannot recur here at all. The agreement check proved the two version regexes were byte-identical while they behaved differently, and reported that as "the service.version shape is install.sh's own release-tag gate" — a claim about behaviour that byte-identity does not support, because each side was matched with a different operator. It now checks both: byte-identity, then verdict agreement over a corpus, each side evaluated the way the file that owns it evaluates it. The corpus is written down independently of either matcher and the check fails closed if it contains no embedded-newline input, since without one it degenerates into the byte check. 3. exit 2 is the "complete this step and re-run" handoff, not a failure. gpu-nvidia.sh:55 exits 2 after install_nvidia_drivers SUCCEEDED, to ask for a reboot. That call sits under step_header b, so every unattended GPU host's first install booked an `install.run.failed` with error.type=prerequisites_failed — a fabricated prerequisite failure in the rate this ticket exists to produce. Same shape as the --help bug, opposite direction; install_cleanup has treated 2 as its own outcome ("Re-run required") since client#681. It now renders install.run.cancelled and carries no error.type. It rides an existing verb rather than a new one because §6.4's outcome list is closed and adding to it is a PR against the contract, not an emitter's unilateral call; of the registered verbs, `cancelled` is the only terminal one that is true here. exit_code stays on the record, so 2 (handoff) and 130/143 (Ctrl-C) remain separable — which is why the exit code is an attribute in the first place. Event names are now a declared closed set with a guard. The guard derives the emitted names two ways — the literals in the case statement, and what the function actually renders over the installer's exit codes — rather than reading the declaration twice, and checks §6.1's grammar. It cannot check the §6.4 half from this repo: the verb registry is in rfcs, and a hand-copied second list of verbs would be the defect rather than the fix. 4. The chmod ran before the trim replaced the file. `tail > "${spool}.tmp"` creates under the process umask and `mv` keeps the tmp file's mode, so 0600 did not survive. common.sh's `umask 077` normally covers it, but _install_userspace_tools (setup-linux.sh:893) and its macOS twin set `umask 022` and restore it only afterwards. Reproduced: spool 644. The chmod now runs on the inode that survives, before the mv — one chmod, not two, because a second one on the spool afterwards is unreachable belt and braces that no test can redden. The test pinning 600 could not see any of this, because load_lib sources common.sh first and every test therefore ran under 077. There is now one that sets umask 022 and asserts the umask actually took. 5. nit: the comments claimed coverage the file does not have. `bootstrap` means "install-k8s.sh before step a", not "everything before step a" — download and verify happen in install.sh, which never sources this file and whose EXIT trap is `rm -rf "$TMPDIR"`. install.sh in TB_TELEMETRY_SOURCES is unreachable for the same reason: TB_ERR_LOC has exactly one writer, common.sh's _record_err. Both comments now say so. No bootstrap telemetry added. Also noted on install.run.skipped, which reads wider than it is: install.sh:132 reaches a healthy machine and `exec tracebloc`s at :144 before install-k8s.sh is fetched, so on curl|bash the assess gate is never reached at all. Tests: 4 new bats tests (36 in telemetry.bats, 1161 across the suite, all green), 3 new checks in the agreement guard. Every fix mutation-proved: 11 mutations, 11 reddened, each with its anchor asserted. Two first-pass mutations came back inert and are fixed rather than counted — one removed a redundant chmod nothing could observe (the redundancy is now gone), the other rewrote the guard's own detector alongside its corpus so the detector matched its mutated needle.

From 91ce4fac7f0908b8caaae2d9a3843a2c8247926b Mon Sep 17 00:00:00 2001 From: Lukas Wuttke Date: Wed, 19 Aug 2026 10:31:45 +0200 Subject: [PATCH 09/11] fix(telemetry): the fallback was unreachable in the case it was built for (backend#1907) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two Bugbot findings, both reproduced before either was touched. 1. HIGH — a failed data-dir spool write dropped the outcome event. `_telemetry_deliver` had `|| return 0` on both the spool's `mkdir -p` and its append, so a data dir that EXISTS but refuses the write ended the function with the record nowhere — never reaching the $TMPDIR fallback added in 46a33de. That is not an exotic path: HOST_DATA_DIR present but unwritable is precisely when `_choose_log_file` (common.sh:769-775) has already fallen back to a mktemp log, and on curl|bash that log sits in the bootstrap's own doomed TMPDIR, so the `log` line kept nothing either. The fallback existed and was unreachable in exactly the case it was written for. Reproduced both halves, each with an anchor proving the fixture was not inert: * a 0500 data dir with no telemetry/ yet. Anchor A: `_choose_log_file` really does fall back out of that dir (called, not asserted). Anchor B: telemetry/ was not created afterwards, so the mkdir really failed. Result: no data-dir spool, no fallback file. The event was gone. * pending.jsonl replaced by a directory, so the append cannot open it. Same result, and it holds for root too. Both now fall through. The single-write guarantee comes from control flow rather than a flag: the `return 0` sits after a SUCCESSFUL append and nowhere else, so the fallback is reachable only on a path that wrote nothing. Everything after the append — chmod, trim, mv — may fail freely, because the line is already on disk and re-filing it would turn one install into two rows. The control case still writes exactly one spool line and zero fallback files. The trim moved into `_telemetry_trim_spool` so the append's success is the last thing in that branch. Inline, the trim sat between the append and the return, which is what made it easy to write the `|| return` that skipped the fallback decision in the first place. Also fixed on the same line: `2>/dev/null` now precedes the `>>`. Redirections apply left to right and a failing `>>` is reported by the SHELL, not by printf, so the old order printed `…/pending.jsonl: Is a directory` — with the customer's path — out of an EXIT trap. 2. LOW — a line number was emitted with no file to attach it to. `tracebloc.install.source` and `tracebloc.install.source_line` were two independent gates over one fact. A location whose basename is outside TB_TELEMETRY_SOURCES dropped the file and kept the number. Reproduced: `/home/someone/evil.sh:9` rendered `"tracebloc.install.source_line":9` with no source key, and so did `?:118` — the shape the ERR trap produces whenever BASH_SOURCE is empty, which is a real installer path, not a synthetic one. A line with no file is not a partial answer; it is a confident wrong one. The gate is now `_telemetry_source_basename`'s own exit status, so TB_TELEMETRY_SOURCES stays the single declaration of what counts as one of our files. Deliberately not gated the other way: TB_ERR_LOC has exactly one writer in the tree (install-k8s.sh:118) and it always appends `:${LINENO}`, so source-without-line is unreachable — a branch for it would be belt and braces no test could redden. A file with no line is honest information anyway. Mutation results — 10 mutations, each asserting its own anchor applied first: M1 both halves return instead of falling through RED M2 only the mkdir half returns RED M3 only the append half returns RED M4 a successful append no longer returns (double file) RED M5 source and line gated independently again RED M5b the same mutation vs the PRE-EXISTING source test RED (it now covers the line) M6 common.sh dropped from TB_TELEMETRY_SOURCES GREEN — survivor, by design M6b cluster.sh dropped (the anchor names it) RED M7a the trim's else-branch cleanup removed RED M7b a failed trim treated as success RED M7c the trim is never called RED M7d a failed mv leaves the trimmed copy behind RED M6 is a deliberate survivor and is reported rather than hidden: the pairing test derives its expectation FROM the vocabulary, so a consistent removal moves both sides. Verified that the gate which owns the vocabulary catches it instead — telemetry-vocabulary-agreement.sh goes red with "source basenames disagrees with gen-manifest.sh's FILES array". The independent anchor at the end of the pairing test also names cluster.sh in its own right, which is why M6b reddens. M7 found a defect in this commit's own first draft. The trim-failure fixture broke `tail` with a PATH shim, and common.sh:8 PREPENDS the system directories to PATH, so the real `tail` ran and both assertions passed against a trim that had worked perfectly. Rewritten to use a shell function — which beats PATH lookup outright — plus a behavioural anchor: SPOOL_MAX=3 against 7 spooled lines must leave 7, or the trim ran after all. scripts/manifest.sha256 regenerated (Static analysis R8). Full suite: 1168 bats tests green. `make lint` clean; telemetry.sh clean under `shellcheck -S warning -x` and `bash -n` on bash 3.2.

The 130/143 branch of telemetry_render_event booked `cancelled` without consulting `_TB_TELEMETRY_SKIPPED`, so Ctrl-C on that screen — the most ordinary thing a user does there — filed a cancelled install for a run that installed nothing. Reproduced through the real INT and EXIT traps, not just the render function, with the skipped latch set identically in both arms: skipped run, ordinary exit 0 -> install.run.skipped skipped run, then Ctrl-C (130) -> install.run.cancelled <- the defect `cancelled` asserts that an install was cancelled. On this path there was no install to cancel, and the row would land in the denominator of "how often do installs not complete" — inflating it with runs that never attempted anything. Same class and same direction as the `--help` bug fixed earlier on this branch: it makes the product look worse while telling nobody anything actionable. No contract change. §6.4's verb list is untouched — no verb added, removed or redefined. Both `skipped` and `cancelled` were already registered and already emitted by this file; only which of the two a given run books changes, and `skipped` is the true one here. A wrong verb from a closed list is an ordinary defect. SKIPPED DOES NOT WIN OVER A FAILURE, and the asymmetry is deliberate. The flag is consulted only on the exits that mean nothing was installed — 0 and the two signals. A skipped run that then dies with a real non-zero stays `failed` and keeps its error.type, so the `*)` branch does not look at the flag. The shorter spelling — hoisting a blanket "skipped wins" ahead of the case — would have hidden a genuine failure, which is why it is not used and why there is a test for it. The comment claiming 130/143 were "unconditional" is now false and was rewritten rather than left to mislead the next reader. Mutation results, each asserting its anchor applied first: N1 130/143 unconditional again (the reported defect) RED N2 130/143 ALWAYS skipped (deletes the cancelled signal) RED <- positive control N3 the flag test inverted RED N4 only 130 consults the flag, 143 forgotten RED N5 blanket skipped-wins hoisted ahead of the case RED N5b only the failure branch consults the flag RED N2 is the control that matters: without it, "renders skipped" would be satisfied by a change that never renders cancelled at all, which would silently delete the interrupted-install signal. N5b exists because N5 tripped an earlier assertion (exit_code) before reaching the failure-swallowing one — it mutates only the `*)` branch, leaving exit_code untouched, and proves that assertion is live rather than decorative. telemetry-vocabulary-agreement.sh still passes unchanged: the case statement gains no new event-name literal, and its (b) sweep already exercised 130 x skipped=1, so the input domain was already derived from the producer. scripts/manifest.sha256 regenerated (Static analysis R8).

From d3aa8382d4dc3b959bbb1d04bfce4251b649571b Mon Sep 17 00:00:00 2001 From: Lukas Wuttke Date: Wed, 19 Aug 2026 12:13:13 +0200 Subject: [PATCH 11/11] test(telemetry): allowlist the canary curl -u fixture in .gitleaks.toml (backend#1907) The telemetry canary tests feed a fabricated `curl -u $CANARY:hunter2` through the redaction guards to prove they strip credentials. The value is never a real secret, but a git-mode range scan keeps re-finding it in earlier commits of this branch (commit 72af29e8) even after the fixture was refactored, so a code change cannot clear it. Per code-quality.yml, a deliberate false positive belongs in .gitleaks.toml (commit-independent), not the baseline. Scoped to the exact canary match; default rules extended.
