| # THE TWO CANARIES OVER THE MATRIX, NIGHTLY (design 2026-11-12 §5.7). | |
| # | |
| # tests/canary/c (C89 on POSIX alone: two programs from one set of sources, a | |
| # resource script written once, a non-local jump, files, the arguments) and | |
| # tests/canary/cxx (C++23 modules, `import std`, exceptions, threads, a test) | |
| # are built, linked statically, run, tested and packed for every identity the | |
| # host's rows of tests/canary/matrix.tsv name, with this commit's mcpp. Each row | |
| # states what the step does (ok, fails with a note, n/a); a cell that differs | |
| # from its row, either way, fails the job, so the table is a declaration that | |
| # a change of behaviour corrects. The report of each host is the job's | |
| # summary and its artifact `canary-report-<host>`; a statement such as "every | |
| # identity builds" cites a run of this workflow. | |
| # | |
| # Nightly, by hand, and on a pull request labelled `ci:canaries`; no pull | |
| # request waits for it otherwise. | |
