When a test redefines a C primitive (or a native-compiled function), native-comp routes native callers through a trampoline that calls the mock with the primitive's maximum arity. A fixed-arity mock narrower than the primitive then throws wrong-number-of-arguments, intermittently, as the eln-cache fills. I swept every arity-narrow subr mock to append &rest _ (188 sites, preserving any named args the body uses), and added tests/test-meta-subr-mock-arity.el, which fails make test on any subr mock too narrow for the primitive's arity. The rule isn't "never mock a subr". The suite mocks message and completing-read freely. It's "a subr mock must accept the primitive's arity." Background, the three failure modes, and the research are in docs/native-comp-subr-mocking.org. 2026-05-25T22:51:17+00:00 Craig Jennings c@cjennings.net 2026-05-25T22:51:17+00:00 urn:sha1:f867f50d1675d5f9a251f7b5a2633d2eac3f0de7 Four export/publishing commands shelled out to external tools without checking they exist, so a missing tool surfaced as an opaque process error — or, for reveal.js, a silently broken presentation. I added a command-time guard to each that names the tool and what's needed: - zathura, in the pandoc PDF export-and-open command - the hugo binary and the platform file-manager opener, in hugo-config - the local reveal.js checkout (run scripts/setup-reveal.sh), shared by the reveal export and preview commands - pandoc, in the web-clip protocol handler The checks run only when the command runs, so startup stays quiet. Each guard has a test asserting the user-error fires when the tool is absent, and the existing happy-path tests now stub the lookups so they exercise the real path rather than tripping the new guard. 2026-02-14T06:45:55+00:00 Craig Jennings c@cjennings.net 2026-02-14T06:45:55+00:00 urn:sha1:acf7034fa94102b9df30774986ec4dfe2582a9ad Add 67 tests across 6 new test files for modeline and hugo modules. Refactor hugo-config: extract post-file-path and post-template helpers from interactive new-post function for testability. Update todo.org with test audit (31 modules), priority adjustments, and task cleanup.
