| # mcpp driving the xlings-MANAGED MSVC toolset (`msvc@<toolset>`) — the whole | |
| # chain, end to end: index → payload → unpack → resolve → build → run → | |
| # remove. | |
| # | |
| # WHY THIS IS NOT IN ci-windows-e2e.yml, which also runs MSVC tests: | |
| # | |
| # Different subject. Everything MSVC in the main suite (95_msvc_system, | |
| # 99_msvc_native_build, 177, 180, 182) tests mcpp against the machine's own | |
| # Visual Studio. That is mcpp's code and nothing else's. This job tests | |
| # mcpp against the xlings ECOSYSTEM — a package index, a mirror, a payload | |
| # set, an unpack recipe — most of which lives in another repository and | |
| # moves on its own schedule. | |
| # | |
| # Different failure meaning. When this job goes red it usually means the | |
| # index moved, not that the pull request broke something. Mixed into the | |
| # main suite that reads as "your change broke Windows", and the honest | |
| # signal (100+ fast tests, all about mcpp) gets buried under one slow test | |
| # about somebody else's package. Keeping them apart keeps both readable. | |
| # | |
| # Different cost. ~380 MB of downloads (xim:msvc + xim:windows-sdk) and a | |
| # real toolchain install, against a suite whose other tests are seconds | |
| # each. | |
| # | |
| # The split is enforced by a capability, not by a file list: the tests carry | |
| # `# requires: xlings-msvc`, granted only by MCPP_E2E_XLINGS_MSVC=1 below. So | |
| # the main suite skips them by construction, and a new test joins this job by | |
| # declaring the capability — there is no second list to keep in sync. | |
| # | |
| # Paired workflows: ci-windows.yml, ci-windows-e2e.yml. | |
