From 7bfa53f1ffe6c41d2a603de2d37e5e740a25182e Mon Sep 17 00:00:00 2001 From: "Jonathan D.A.

That could never succeed, for two independent reasons, both verified empirically against the exact image: 1. `curl` is NOT installed in arangodb:3.11. Present instead: wget, nc, arangosh. (curl/python3/openssl all MISSING.) 2. `localhost` inside the container resolves to `::1` first (/etc/hosts maps both `127.0.0.1 localhost` and `::1 localhost`), but ArangoDB binds IPv4 only. Probing `localhost` returns "Connection refused"; probing `127.0.0.1` returns {"server":"arango","version":"3.11.14"}. Net effect: the server logged "ArangoDB ... is ready for business" and was then killed by Actions with "Failed to initialize container arangodb:3.11 / One or more containers failed to start". This is why `Integration Tests` and `Haskell Integration Tests` were red on main — not a code fault. Fix: use wget (present in the image) against 127.0.0.1 (actually listening). Applied to all three arangodb service definitions in this workflow.

I documented the health-check reasoning with `#` comments placed INSIDE the `options: >-` block. In a YAML folded scalar `#` is not a comment — it is literal text — so the prose was folded into the docker arguments: docker create ... # `curl` is NOT installed in arangodb:3.11 ... --health-cmd ... invalid reference format ##[error]Exit code 1 returned from process: file name '/usr/bin/docker' The container never even got created, so `Integration Tests` and `Haskell Integration Tests` failed earlier than before rather than passing. Comments moved above the `options:` key, where they are real comments. Verified by parsing the workflow and asserting on the FOLDED VALUE — the check I should have run before pushing, rather than eyeballing the source: [integration-tests/arangodb] --health-cmd "wget -q --spider http://127.0.0.1:8529/_api/version || exit 1" --health-interval 10s --health-timeout 5s --health-retries 10 ... 5/5 service option strings start with a flag and contain no '#'. RESULT: CLEAN The underlying fix (wget + 127.0.0.1, verified healthy in 15s against the real image) is unchanged.

Jewell" <6759885+hyperpolymath@users.noreply.github.com> Date: Tue, 21 Jul 2026 13:02:08 +0100 Subject: [PATCH 3/5] fix(ci): Integration Tests ran `mix test` with no BEAM; harden arango start-up MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two further faults, both found by reading the real CI run of the previous commit rather than assuming it was done. 1. `Integration Tests` died with **exit 127 — command not found**. The job installs the RUST toolchain (dtolnay/rust-toolchain), then runs `mix test --include integration`. There is no erlef/setup-beam anywhere in that job, so `mix` was simply not on PATH. Added setup-beam + `mix deps.get` before the Elixir step, pinned identically to the E2E job (OTP 27.0 / Elixir 1.17) so the two jobs cannot drift apart. 2. `Haskell Integration Tests` still reported "Failed to initialize container arangodb:3.11" **despite carrying the corrected health probe**. In the same run, `Integration Tests` reported "arangodb service is healthy" at 07:37:03, so the probe itself is right — the Haskell job's instance simply did not finish starting inside the retry budget while both jobs contended for the runner. ArangoDB's first boot is two-phase: it initialises, logs "server will now shut down due to upgrade, database initialization or admin restoration", exits, and only then restarts for real. Failures during that window were being counted against --health-retries. Added `--health-start-period 40s` to all three arangodb services, which is exactly what that flag is for: failures inside the start period do not count toward the retry budget. Verified: * flag accepted by docker against the real image; healthy in 15s * folded-scalar assertion re-run — 5/5 service option strings start with a flag and contain no '#'; start-period present on all three arangodb services (this is the check that caught the comment-folding regression two commits ago, so it now runs every time) * step order asserted programmatically: setup-beam at index 9 precedes `mix test` at index 11 Evidence the previous commit DID work, for the record: that run reached "arangodb service is healthy" and "dragonfly service is healthy", and ArangoDB accepted writes ({"error":false,"code":201}). The container barrier is cleared; these are the next two faults behind it.

ArangoDB health probe: 401, always `/_api/version` requires authentication whenever ARANGO_ROOT_PASSWORD is set — and busybox wget (the only HTTP client in arangodb:3.11) has no --user/--password option at all, so the probe *cannot* be authenticated. Measured against the real image, polling once a second for 25s: /_api/version exit 1 at EVERY timepoint (401) /_admin/server/availability exit 1 for 3s, then exit 0 onwards So the probe never succeeded, on any job, ever. What varied was whether the runner's own health poll happened to read .State.Health.Status before Docker had recorded any health state — reading empty and reporting "healthy". That is why one job logged "arangodb service is healthy" *before* the container logged "Initializing root user", while another job in the same run went starting -> starting -> unhealthy and failed. The earlier "verified healthy in CI" on this branch was therefore a won race, not a working probe. Switching to /_admin/server/availability (the unauthenticated liveness endpoint) removes the race entirely. ## 2. stress-test: one real step, two fakes, one impossible Confirmed by matching ##[error] line numbers to ##[group] boundaries: - "Concurrent operations stress test" globbed `./target/release/*`, which matches build directories (build/, deps/, examples/, incremental/). It printed "Permission denied" 100 times out of 100 and still reported SUCCESS, because a bare `wait` returns 0 regardless of its jobs. - "Memory pressure test" ran `ulimit -v 512000; cargo test --release`. 500MB of virtual address space cannot host rustc's LLD linker; it aborts with "Resource temporarily unavailable" / "ld terminated with signal 6". The same build scripts compiled fine in the immediately preceding step, which set no ulimit — that in-log A/B is the proof. This step failed on 6 of 6 recent runs. It could never pass. - "Long-running scenario test" ran valgrind over the same directory glob and ended in `|| true`, so it neither ran nor could fail. Removed rather than left reporting success without testing anything. Replaced with steps that resolve real bin targets from cargo metadata (so they cannot rot when a binary is added or renamed), assert every concurrent launch exits 0, and apply the memory cap to the BINARY rather than to the compiler. ## Verified locally against the real binaries, not asserted cargo metadata resolved: cicd-fixer cii-registrar forge-adapter hyper all four --help -> exit 0 all four under a 1GiB VA cap -> exit 0 100 concurrent launches -> 0 failures plus a YAML check that every service `options` folds to a value starting with a flag and containing no '#', and that no arangodb service still references /_api/version.

Jewell" <6759885+hyperpolymath@users.noreply.github.com> Date: Tue, 21 Jul 2026 13:48:21 +0100 Subject: [PATCH 5/5] =?UTF-8?q?fix(ci):=20remove=20orphaned=20Haskell=20jo?= =?UTF-8?q?b=20=E2=80=94=20its=20project=20was=20deleted=20in=20March?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `haskell-integration` ran `cabal build all` / `cabal test all` with `defaults.run.working-directory: registry`, and cached on `hashFiles('registry/hypatia.cabal')`. `registry/` does not exist. It was deliberately deleted in f2fe2df (2026-03-06), whose own commit message says: Remove registry/ (30 files - Haskell, superseded by Elixir) The CI job was left behind. It has failed EVERY run since: 11 failures and 1 cancellation across the last 12 runs, never once green. The repo now contains 0 .cabal files, no cabal.project, no stack.yaml, and one .hs file — test/soundness/fixtures/code_safety/unsafe_coerce.hs — which is a scanner test fixture, not a Haskell project. Until this branch it was masked: the job died at container startup because the arangodb health probe could never pass. With that fixed the container comes up healthy and the real error surfaces: ##[error]An error occurred trying to start process '/usr/bin/bash' with working directory '.../hypatia/registry'. No such file or directory Removed the job and its two references in the `integration-status` roll-up (`needs:` entry and the `needs.haskell-integration.result` expression), which is what kept that gate red as well. Each run had been installing GHC 9.6 + cabal 3.10 and standing up an ArangoDB service container before failing at its first `run:` step, so this also stops burning those runner minutes. Verified: YAML parses; `haskell-integration` absent from jobs; zero dangling `needs:` entries and zero dangling `needs..result` expressions anywhere in the file; service-options and arango-probe assertions still pass.
