From 0aa85dd219f4be8dbf3383661fd2b42370945b87 Mon Sep 17 00:00:00 2001 From: Craig Jennings Date: Sun, 21 Jun 2026 03:19:08 -0400 Subject: test: make subr mocks variadic for native-comp, add arity meta-test Re-enabling native-comp surfaced a suite-wide fragility. 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. --- tests/test-org-webclipper-commands.el | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'tests/test-org-webclipper-commands.el') diff --git a/tests/test-org-webclipper-commands.el b/tests/test-org-webclipper-commands.el index be7fc38cf..fb693192f 100644 --- a/tests/test-org-webclipper-commands.el +++ b/tests/test-org-webclipper-commands.el @@ -120,7 +120,7 @@ that registers the webclip entry.
