Hermit compatibility

Hermit compatibility scorecard

Test results for Hermit's Linux execution backends.

1 test attempt from 1 validation run is not counted on this site.

These attempts appear in their validation runs but are missing from the published result history. The list below explains why. They do not affect this site's totals; their run pages still show the recorded results.

The page of rows the site did not count, and why lists the same runs with their row counts.

Hermit makes Linux execution repeatable by controlling scheduling, time, and randomness. This scorecard compares its backends: determinism asks whether repeated runs agree, while parity asks whether a backend agrees with the reference ptrace backend. Each cell is one workload, execution mode, and backend; results distinguish passes, failures, and unmeasured cells. Latest selected measurement: ; latest history entry: . Totals may combine qualifying results from multiple runs; rebuilding this website does not rerun the tests. For context, start with the introduction to Hermit, or visit the README for setup and usage.

Overview

4,309 measured or runnable cells across 619 tests. Each cell is one test, mode and backend.

3 / 4,309 cellsNever measured

45 of these pass on measurement but are disabled by current policy.

All 619 tests, by category. A test can run in several modes and on several backends.

Explanation

619 tests × 19 cells per test = 11,761 cells in the manifest. The 19 are 3 modes (chaos, replay, verify) × 6 backends (dbt, in-guest-trap, kvm, liteinst, ptrace, sabre) + 1 naked/native.

Current policy can run 3,456 cells during normal validate testing and disables 5,783 combinations. Restrictions include unsupported modes or backends and test-specific limits. Measured results still count when a combination is disabled. 2,522 other cells have no conclusive result and are listed in the data audit. 3,456 + 5,783 + 2,522 = 11,761 manifest cells.

Overview counts use 4,309 cells from existing tests: 4,306 have a result and 3 have no usable measurement. Green means the test passed; red means it failed or timed out. Recorded results count regardless of whether the current CI policy runs the combination. Combinations with no usable result count here only if current policy runs them during normal validate testing. 2,522 other manifest cells have inconclusive or conflicting results; the data audit explains each omission.

How determinism is tested. Run the program twice under Hermit. Compare its guest syscall logs, recorded memory checks, outputs and exit status. The recorded details must match. A pass without this log comparison does not count as a determinism match.

Backend comparison. The determinism number of every backend uses the same 618 verify tests. These are the verify tests with a recorded ptrace result, including failures. Replay and chaos are shown in their own columns, each over its own cases (597 replay and 7 chaos), and are not part of the determinism number. Recorded comparisons count regardless of whether the current CI policy runs the combination. In the full-match column, failures and cases without a matching comparison earn no credit but stay in this shared denominator. This measures backend coverage of the reference tests.

0 ptrace test-and-mode cases use a reduced log comparison (comparator: stripped). They are excluded from every determinism denominator because they do not check for a bit-for-bit match.

With partial credit. Full matches earn one point. A diverging run can earn a fraction based on its first differing scheduler turn and the length of a complete ptrace run at the same commit. Missing measurements earn no credit. The table shows the total points as a decimal, divided by the same reference count.

The recorded history contains 302,997 observation rows representing 309,039 test runs, including older results. Validation runs and the data audit give the details. Custom validation commands.

Determinism and Backend Parity

Determinism

Each backend uses the same verify tests; replay and chaos are shown separately. Methodology and denominators.

Parity (measured after determinism)

Parity compares a backend's log with ptrace's after both pass the repeatability check. The compared backends are kvm, liteinst, sabre, dbt, in-guest-trap; their test inputs must match. A full log match scores 1. Otherwise, the score is the matching start of the logs divided by the length of the longer log. Parity = matching INFO logs; partial credit = matched prefix / longer log. Parity has its own denominator: tests selected for ptrace verification, on each candidate backend. Tests without a usable ptrace log, cases with incompatible inputs, and cases omitted from a sampled run are excluded. Disabled, missing or failed candidate results score 0.

Newest 20 runs per host and producer, plus current headlines and pinned or retracted runs; 1,243 runs archived. Row and run counts describe this retained window.

Stale: this summary covers the parity store at ledger commit e41d79579a5e9534282562df0ce70dfb96e72c19; 3,055 newer parity record line(s) at ledger commit 1f6faf64585788e2311624771589776598c580dd are not summarized. The figures below are as of e41d79579a5e9534282562df0ce70dfb96e72c19. A parity-only publication appends records without rewriting the summary, and a validation's publication rewrites it at most once every two hours (later ones defer); the next scorecard publication after that, or the nightly ledger maintenance at 3:00 AM US Eastern, summarizes them.

233 parity run(s) recorded no parity rows: append-parity refused their records. They are not in any figure below; the parity details page lists them.

This run covers 606 of the 618 verify tests: those whose ptrace verify cell full validation runs, which gives it a reference log. The other 12 are not in this run: 5 large programs run only by the super suite, 7 disabled, failing or otherwise not selected. See hermit issue 4269.

The 12 verify tests outside the parity population, and why
  • c-programs/child-subreaper-refusal: ptrace verify is disabled: The ptrace backend supports the subreaper prctls since https://github.com/rrnewton/hermit/pull/4000, because Detcore's wait model re-parents orphans there; c-programs/child-subreaper-support asserts that instead
  • c-programs/dbt-unsupported-syscall: not run by full validation: This fixture intentionally invokes restart_syscall, which strict ptrace execution rejects as Unsupported and fails closed; the cell needs an expected-refusal contract or syscall support before it can be required validation.
  • compat/java: large program, run only by the super suite
  • compat/javac: large program, run only by the super suite
  • compat/logger: not run by full validation: In the pinned image, logger (nix util-linux) opens /dev/log even with --stderr --no-act and exits 1 with no journal socket present, and pkg-config is pkgconf, which emits -D before -I where the workload asserts freedesktop pkg-config's file-order output (https://github.com/rrnewton/dev-hermit-beads/blob/main/issues/dh-jn0hh.md)
  • compat/node: large program, run only by the super suite

  • compat/rustc: large program, run only by the super suite
  • compat/timeout: large program, run only by the super suite
  • shared-futex-c/qemu-exec-init: not run by full validation: Repeated canonical verification retained an understood infrastructure failure; this cell did not pass every repetition cleanly.

parity-all run pressure-d44b1911e009-20261022T051816Z-parity-all

This is a parity-all run: every verify cell of every test in the parity population, on ptrace and on every candidate backend, whatever the manifests enable. A candidate the manifests disable ran as a parity probe on ptrace's guest arguments (with --max-timeslice=disabled on liteinst and in-guest-trap), not as its manifest describes it, so its credit says how far its log follows ptrace's on the same inputs; it is not evidence that the cell can be enabled.

Backend history

Results as of each UTC date, using tests in the current manifest. Determinism (the default) covers the verify tests; Replay and Chaos each cover their own cases. Each date uses its own measured ptrace reference count. Parity shows the latest full-validation parity run, one point per backend: the parity summary keeps per-backend results only for the latest run. A step holds the last recorded result; a gap means no comparison was recorded. Results can fall after a regression.

Use the chart: Choose a metric, and choose Percent (the default) or Green cells: raw counts show a backend still gaining cells while a growing reference count lowers its percentage. Hover over or focus a point to see its exact date and values. Clear or select a checkbox under Visible lines to hide or show that series.

Record/Replay

A replay cell records the program under ptrace (record start --strict --verify, in an isolated recording directory), then replays that recording; the harness compares the two runs. Green and red count the latest recorded result; determinism matched counts the cells whose repeated runs agreed. No replay cell is runnable on dbt, in-guest-trap, kvm, liteinst, sabre: current policy disables these mode/backend combinations.

First-parent depth counts commits along the revision’s first-parent chain, including the revision itself. All reachable commits also counts merged side branches. These are recorded Hermit history counts, not elapsed time or a claim that a revision is that many commits behind main. A distance requires a verified ancestry relationship. Missing or conflicting depths are not inferred.
