From 29cdaa4de39ad731eb878a87f6e735623363b0f3 Mon Sep 17 00:00:00 2001 From: jochen Date: Mon, 31 Aug 2026 00:25:19 +0200 Subject: [PATCH 01/78] Prove a machine filters what it was told to and nothing else MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Written and loaded are different things, and loaded and enforcing are different again. The test opens two ports on a machine, declares one of them, and checks from the other machine that the declared one answers and the undeclared one does not — then removes the module and checks the port closes with nobody editing a rule. The base image gains nftables, read back through `nft --version` like the other three: a machine that cannot load a rule set applies the mesh's filtering, reports success and filters nothing, which is the exact fault the derivation exists to remove. Two earlier tests were asking for things that are not there. The lab's registry drops tags when it stocks, so `registry:2` is not served and the mirror test failed with "not found" — it now uses the pinned digest, which is what a declaration carries anyway. --- scenarios/two-nodes.yml | 4 + src/lifecycle/base.ts | 19 ++++ test/integration/mesh.test.ts | 187 ++++++++++++++++++++++++++++++++-- 3 files changed, 201 insertions(+), 9 deletions(-) diff --git a/scenarios/two-nodes.yml b/scenarios/two-nodes.yml index bf2414f..195f4a4 100644 --- a/scenarios/two-nodes.yml +++ b/scenarios/two-nodes.yml @@ -24,6 +24,10 @@ images: - postgres:17-alpine - cloudamqp/lavinmq:latest - mesh-control:development + # So a module can mirror one into a registry of the mesh's own.

It is that nobody notices it stopped running (novox/hq 04-ISSUES/005). The harness this replaces had not built for two and a half months and nothing said so — and this suite needs a hypervisor, so it inherits exactly that: it runs when somebody remembers, and remembering is not a mechanism. So running, recording, and rebuilding are one act: - the host binary, control-plane image and builder are rebuilt from source first. The last two both parse manifests; building one and not the other left a binary eleven hours old refusing a field the mesh had just renamed, found by a full run. - a receipt lands in XDG state — outside git, because the question is whether *this machine* has run it, and a receipt in git would be a claim about everybody's machine made by whoever committed last. - `last-run` judges it and exits non-zero when it no longer counts. Three faults found by running the thing rather than reading it, each now held by a test confirmed to fail without it: - counted() passed every test while parsing nothing. The runner colours its summary even into a pipe; the fixtures were clean text that had been imagined rather than captured. A fixture that agrees with the mistake proves the mistake. - a receipt for `suite test/lastrun.test.ts` was indistinguishable from one for the real thing — 005's own symptom, rebuilt inside its remedy. The receipt now records what ran. - a tree with uncommitted work reported the bare commit, claiming coverage of code nobody can check out. Nothing else could tell: the hash is identical either way.

Against a real server rather than a stub, because what is under test is whether an order, a challenge and a handshake agree, and a stub would be told to agree. One assertion passes and one fails, and the failure is filed as novox/hq 04-ISSUES/020: the authority issues a certificate and the client never collects it. Kept as a failing test rather than deleted or skipped — it is the reproduction, and it proves everything up to the last hop. The passing one is the guard that matters day to day: no certificate is ordered for a name the mesh does not route, so a scan cannot spend an account's rate limit.

The first module that could not have been declared this morning: it needs the network shape and it needs a sealed value to reach a container's environment. Its password is accepted rather than generated, which is the whole shape of an adoption: a service that already exists keeps the credential it already has. Asserted properly — a wrong password is refused by the same database, so the passing case means something. **The warm scenario.** A mesh kept between runs and returned to, which turned twelve minutes of bootstrap into thirty seconds of restore. Off unless asked for: a run that is meant to mean something raises from nothing. Its guard fired for real during this work, unprompted — a mesh-host commit landed and it refused the stale base, naming both commits, rather than passing tests against yesterday's binary. That is 04-ISSUES/005's rule one level down. Three things the guard learned the hard way and now handles: a snapshot captures disk and not memory, so the host is restarted after a restore and asserted to have come back; the stocked image digests are worked out while raising and a restored instance never raises, so they are kept; and comparing only the repositories this run can see clears the ones it cannot, so both directions are compared. The one real bug behind five failed attempts was in mesh-host and it reported itself precisely: a network shape the language had and no host implemented. Everything else was scaffolding of mine. --- scenarios/two-nodes.yml | 4 + src/cli.ts | 35 ++++++ src/warm.ts | 210 ++++++++++++++++++++++++++++++++++ test/integration/mesh.test.ts | 188 ++++++++++++++++++++++++++++-- test/warm.test.ts | 61 ++++++++++ 5 files changed, 490 insertions(+), 8 deletions(-) create mode 100644 src/warm.ts create mode 100644 test/warm.test.ts diff --git a/scenarios/two-nodes.yml b/scenarios/two-nodes.yml index 42858e5..225a0a6 100644 --- a/scenarios/two-nodes.yml +++ b/scenarios/two-nodes.yml @@ -28,6 +28,10 @@ images: # what the mesh's registry is built from — the same chicken-and-egg the bootstrap has, resolved # the same way. - registry:2 + # A real third-party workload, for adopting one the way the conversion will.

Two things that made this cost hours rather than minutes are fixed with it.

A run stalled for thirty-five minutes and said nothing. The cause was a link systemd was still configuring, three layers down inside a `docker load` blocked on a socket — and every one of those layers knew what it was waiting for. None of them said so. Three decisions, each doing work. **Every external command is logged, at the three places that run one.** Ninety-seven call sites reach a hypervisor or a container runtime through three wrappers, so instrumenting the wrappers covers all of them and nothing has to remember to log. **A command still running says so while it runs.** A line before and a line after tells you nothing until the after arrives, which is exactly the case that matters. Anything outstanding past fifteen seconds reports itself with how long it has been going. It is reported as still running, not as stuck — which it is is not knowable from there, and a log that calls a slow step a hang teaches people to ignore it. **It goes to a file, written synchronously.** Node block-buffers stdout when redirected and a test runner buffers it again, so a console log can sit minutes behind. `appendFileSync` cannot lag. Two things this found in itself while being written, both the same shape as what it exists to catch: A question that answers no is not a fault. Half the lab's commands are questions — does this network exist, is the agent up yet — and they fail constantly while a scenario comes up. Logging those as faults filled a healthy run with ✗, which is how you end up ignoring ✗ when one is real. They are recorded quietly now, and still recorded. And `around` skipped its own wrapper when a step's level was below the configured one — taking the failure line and the heartbeat with it. The two things worth having at a low level were the two that vanished at exactly the level somebody would use. The gate belongs in `write`. Also unsilences the four call sites that passed a callback throwing everything away, including the one the stall sat in, and tees `raise`'s progress into the file whether or not a caller asked to see it — the end-to-end test passed no callback, so the one run that mattered reported not a single step. --- README.md | 21 +++++ src/incus/client.ts | 30 ++++++- src/lifecycle/place.ts | 16 ++++ src/lifecycle/raise.ts | 55 ++++++++---- src/lifecycle/registry.ts | 20 ++++- src/lifecycle/router.ts | 6 +- src/log.ts | 163 ++++++++++++++++++++++++++++++++++++ test/log.test.ts | 172 ++++++++++++++++++++++++++++++++++++++ 8 files changed, 464 insertions(+), 19 deletions(-) create mode 100644 src/log.ts create mode 100644 test/log.test.ts diff --git a/README.md b/README.md index 67eba59..39a6014 100644 --- a/README.md +++ b/README.md @@ -165,6 +165,27 @@ If it says the daemon is not reachable, the group grant postdates the shell. `ne but a heredoc into `newgrp` runs the suite as a child of a shell that then exits — start it with `setsid nohup … &` inside the heredoc, or the run dies with the shell that launched it. +## When something takes too long + +```sh +export MESH_LAB_LOG=info # or debug, or trace +export MESH_LAB_LOG_FILE=/tmp/lab.log # unset writes to stderr +``` + +| level | what it adds | +|---|---| +| `info` | each step of a raise, with how long the previous one took; anything that failed; **and a line every 15s naming whatever is still running** | +| `debug` | every command the lab runs — incus, docker, and anything local — with its duration, and the stderr of anything that failed | +| `trace` | what those commands printed | + +**The heartbeat is the point.** A stall is a command that started and has not finished, and the +only thing separating it from ordinary work is how long it has been going — which nothing can tell +you unless something is still counting.

That proves the control plane and the host agree, and proves nothing about whether the thing described works — which is how five modules sat pinned to images that did not exist while parsing and resolving perfectly. The forge is the right one to run first. It needs a database from another module, a password it did not choose, and a connection string it could not have written itself: the address and port come from what the database serves, the user name from what the mesh decided both ends would call it. If any of that is wrong it cannot start, and nothing else in this suite would notice. The test checks the chain in the order it has to happen — the login exists, the database it owns exists, the forge answers, and its log does not say authentication failed. That last one matters: a forge that started and could not reach its database would still answer on its port. Rewriting image references is now shared rather than copied from the bundle, which had the same problem first. A digest is not knowable until something is built, and when it is, it belongs to whichever registry served it — so the text says which image and the scenario says which copy. Matching is on the repository, with a test that a repository ending in another one is not half-replaced. Also makes the planning test put the machine back. Tests here share one mesh, so the five modules it assigned were inherited by whatever ran next; harmless while nothing pushed, and not harmless now. --- scenarios/two-nodes.yml | 4 ++ src/pinning.ts | 56 +++++++++++++++++++++++++++ test/integration/mesh.test.ts | 72 ++++++++++++++++++++++++++++++++++ test/pinning.test.ts | 73 +++++++++++++++++++++++++++++++++++ 4 files changed, 205 insertions(+) create mode 100644 src/pinning.ts create mode 100644 test/pinning.test.ts diff --git a/scenarios/two-nodes.yml b/scenarios/two-nodes.yml index 225a0a6..b5ae654 100644 --- a/scenarios/two-nodes.yml +++ b/scenarios/two-nodes.yml @@ -40,6 +40,10 @@ images: - mesh-provision-postgres:development # And the proxy, which is what turns a route grant into traffic actually arriving. - mesh-route-proxy:development + # And a forge, so one of the real module descriptions can be started rather than only planned. + # It is the first of them to run: it needs a database from another module, a credential it did + # not choose, and a connection string it could not have written itself. + - gitea/gitea:1.22 place: all: [host, runtime] diff --git a/src/pinning.ts b/src/pinning.ts new file mode 100644 index 0000000..110f2e1 --- /dev/null +++ b/src/pinning.ts @@ -0,0 +1,56 @@ +/** + * Rewriting an image reference to the one a scenario's own registry serves. + * + * **A digest is not knowable until something is built** (novox/hq 04-ISSUES/025).

The planning test added the manifests exactly as they sit on disk, which includes an image the mesh builds — and that image has no digest until it is built, so the file legitimately carries a placeholder. The test was therefore planning something that could never run, which is the whole complaint. It now points the references at this scenario's registry first, exactly as the forge test does. The second is worse and more ordinary. Its cleanup was the last statement in the test body, so the first failure skipped it and left five modules assigned. The next test's push was then refused by a module this one had abandoned — a failure that reads as a fault in the test that was working. Cleanup that only runs on success is not cleanup, so it moved to `after`, where a failure cannot skip it. --- test/integration/mesh.test.ts | 23 +++++++++++++++++------ 1 file changed, 17 insertions(+), 6 deletions(-) diff --git a/test/integration/mesh.test.ts b/test/integration/mesh.test.ts index cf12a4b..821e692 100644 --- a/test/integration/mesh.test.ts +++ b/test/integration/mesh.test.ts @@ -1710,16 +1710,31 @@ test("a third-party workload is adopted, with the credential it already had", { // would live. test("the real modules resolve together, and compose a declaration a host accepts", { skip, timeout: 300_000, -}, async () => { +}, async (t) => { const modules = ["postgres", "keycloak", "gitea", "minio", "mailu"]; for (const name of modules) { const raw = readFileSync( `${process.env["MESH_LAB_MODULES"]}/${name}.json`, "utf8"); - await must("anchor", `printf %s ${quote(raw)} > /${name}.json`); + // Pointed at this scenario's registry before being added, exactly as the forge is. + // + // **Not cosmetic.** Some of these name an image the mesh builds, whose digest does not exist + // until it is built — so the file legitimately carries a placeholder, and composing a + // declaration from it is refused (novox/hq 04-ISSUES/025).

Fixed with `-e` and `--`, which is what those exist for. **The planning test could not redirect what the scenario does not serve.** Rewriting an image reference only works for repositories the scenario's registry actually holds, and the object store's provisioner was not stocked — so that module kept its placeholder and the refusal fired, correctly.

The skip path stays for anything genuinely unserved, and says which module and why: a planning test quietly covering four instead of five is the false coverage this suite exists to prevent. **The forge failed because of the one above it.** The planning test threw before its cleanup could run, leaving a module assigned that refused the next push, so no database container was ever created.

A suite that takes forty minutes is a suite you hear from once a day. Every fault found today would have shown up in the first three minutes of it — a module pinned to an image that does not exist, a consumer given a password and no name to present with it, a credential file nothing could read, a search for a password that read the password as an option. The other thirty-seven minutes proved things that were already working. So this runs first, on one machine, with the three images the mesh needs for itself. It walks one path: a mesh comes up, a module lands, and a consumer gets a credential it can actually use — the name to present, the address, the port, and a password only the host could put there. Deliberately not a smaller copy of the full suite: that path is where everything went wrong, and a canary checking many things shallowly is a canary whose failure nobody can read. `suite` runs it and stops if it dies, saying why rather than leaving somebody to wonder what the missing thirty-seven minutes would have said. Skipped when the caller named its own files. It measured 164 seconds against forty-odd minutes, and failed three times on its first run for one reason: applying the bundle raises a control plane but does not tell it a machine exists.

Reaching in from outside breaks that, so it is opt-in, one scenario at a time, and reversible. `connect` takes an address on the scenario's public link and writes a resolver rule answering everything under each machine's name. `disconnect` gives both back. `connected` says what is true right now, for somebody who cannot remember. It refuses rather than guessing when more than one scenario is standing — the failure being avoided is not an error but one scenario's traffic arriving in another. It also refuses when a machine's name is already answered here for something real, because connecting would point that name at the lab, and the damage would land on the real thing. Names answer with the segment address rather than the overlay one. Inside the mesh a name gives a machine's private address; from here that would need this workstation on the overlay, which is a much larger door. The segment address reaches the same machine and the same ports, which is what opening a board in a browser actually needs. Proven against a live two-node scenario: registry.internal:5000/v2/ answered 200 from this workstation, and so did a wildcard name under the same machine. Disconnect put the address back, stopped answering, and left the real mesh's own names alone. One thing measured rather than assumed: it restarts dnsmasq instead of reloading it. A reload is SIGHUP, which re-reads the hosts file and clears the cache but not the configuration — the rule was written, the reload reported success, and nothing resolved.

The forge failed three runs in a row as "status hangs", and it was diagnosed twice as contention — real defects, fixed, and not the cause. The heartbeats told the truth in the end: every exec on anchor crawled from 15s to 105s, because eleven containers plus a database pull were running in a 1GiB machine. Starvation presents as whatever you were doing when the page-outs start, which is why it wore two other bugs' clothes first. So machine size is now the scenario's to declare — memory and cpus per machine, default unchanged. The anchor that carries the whole substrate is bigger than the laptop that joins it, and the comment on the scenario says why in terms of what lands there. `egress: true` gives a machine one extra interface on a lab-supplied NAT network, addressed by DHCP because the one address a scenario has no business choosing is on the host's side of the fence. Declared per machine and off by default: a closed scenario stays the rule (novox/hq ADR 0016), and the exception exists because a first node fetches its images before any mesh can serve them — which is now the tested path (04-ISSUES/029), and a lab that can never reach upstream cannot prove the bootstrap it exists to prove. The uplink route is metric-4096, so it never shadows a route the scenario declared. A detached machine declaring egress is refused, not ignored. And settled() treats a poll that threw as a poll that missed. An exec timeout at minute four of a wait is "could not ask", not a verdict on the machine. --- scenarios/two-nodes.yml | 7 +++++ src/declaration/parse.ts | 3 +++ src/declaration/types.ts | 25 ++++++++++++++++++ src/declaration/validate.ts | 6 +++++ src/lifecycle/address.ts | 39 +++++++++++++++++++++++++++- src/lifecycle/raise.ts | 49 ++++++++++++++++++++++++++++++++--- test/integration/mesh.test.ts | 12 +++++++-- test/supported.test.ts | 10 +++++++ test/validate.test.ts | 7 +++++ 9 files changed, 152 insertions(+), 6 deletions(-) diff --git a/scenarios/two-nodes.yml b/scenarios/two-nodes.yml index 87d2c4b..cb62fdf 100644 --- a/scenarios/two-nodes.yml +++ b/scenarios/two-nodes.yml @@ -16,9 +16,16 @@ machines: anchor: at: { segment: hosting, address: [192.0.2.10] } inbound: allow + # The whole substrate, the registry, the builder, an adopted workload and the modules under + # test all land here — eleven containers before the forge arrives.
