* Studio: route every Windows setup line through the UTF-8 stdout sink The desktop setup log rendered "?? Unsloth Studio Setup" over a rule of replacement characters. Tauri spawns Windows PowerShell 5.1 with CREATE_NO_WINDOW (install.rs), so the [Console]::OutputEncoding setter throws and both entry scripts rebind [Console]::Out to a UTF-8 writer. step/substep already write only through that writer when stdout is redirected, so they came out right. Every other line did not: Write-Host is written by 5.1's console host with its own writer on the OEM code page, and U+1F9A5 has no OEM form while U+2500 becomes a bare 0xC4, which from_utf8_lossy turns into U+FFFD. The banner and the footer are not steps, so they kept arriving as mojibake, and install.ps1 had neither the IsOutputRedirected probe nor a mirror at all. Add Write-StudioLine above the first write in studio/setup.ps1 and install.ps1: console handle when redirected, Write-Host when interactive, since it is the only writer that colorizes. Rewrite 164 call sites in setup.ps1 and 155 in install.ps1 onto it, including install.ps1's own step/substep. Write-Host now survives only inside helpers that have already ruled out the redirected sink, and the launcher script install.ps1 generates keeps its own, since it runs as a separate process. No behaviour change for an interactive console user: same text, same colors, same single record per line. test_windows_setup_output_encoding.py gains byte-level coverage that the real banner and footer, sliced out of setup.ps1, survive both launch shapes as valid UTF-8 exactly once, plus a source contract that runs on Linux and names any file:line that reaches for Write-Host outside the allow-list. Studio.Setup.Output.Tests.ps1 covers Write-StudioLine in both modes and pins install.ps1's copy to setup.ps1's. Harnesses that splice these scripts apart now stub or dot-source Write-StudioLine: two PowerShell harnesses, one Python harness, and the VC++ redist leg of studio-windows-inference-smoke. pytest tests/python tests/test_installer_*.py: 1077 passed (2 pre-existing sandbox failures unrelated to this change). All 16 tests/studio harnesses and 57 Pester cases pass. Both scripts parse clean. * CI: spawn install.ps1 as a child process so its lines reach install.log * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Stub the output sink in the llama.cpp backend PowerShell harness * Guard the console-less spawn on a Windows runner The byte-level cases in this file run with a console attached, and a GitHub runner gives a CREATE_NO_WINDOW child one, so the UTF-8 setter succeeds there and every version of these scripts emits a clean banner. Those cases cannot tell this fix from what preceded it. Add cases that call FreeConsole() in the child first, which is the state install.rs's own comment assumes CREATE_NO_WINDOW produces. There Write-Host has no screen buffer to query, throws, and takes the script down: 2 bytes of stdout and exit 1 rather than the banner. The probe is assembled entirely out of text sliced from the script under test and spawned with install.rs's own interpreter, flags and creation flags. No Windows job ran this file, so its byte-level half was only ever exercised under pwsh 7 on the Linux Backend CI leg, which is UTF-8 by default. Add it to the cross-platform parity matrix, which already has a windows-latest row and already triggers on install.ps1 and studio/setup.ps1. * Report skips in the parity step A platform-gated case that stopped running on the row it exists for still reports green with -q alone. * Slice the error preference too It is what turns the Write-Host throw into a dead script rather than a skipped line, so restating it would be assuming the result. * Say what the comments actually mean * Make the console-less cases fail on a lost banner, not just a mangled one * Stub the output sink in every harness that splices these scripts The Write-Host rewrite left four spliced-source harnesses reaching Write-StudioLine without defining it. An undefined command is a terminating error, so each one either aborted or was swallowed by the harness's own catch, and the test kept passing while no longer testing anything. - test_windows_python_venv_hardening.py, partial-rollback case: the five-line split-move warning was lost. The assertion that "both halves are named" only stayed green because $existing is a prefix of the rollback dir, so it matched the dir= line instead. Pin it to the warning text. - test_path_probe_access_denied.ps1, ownership guard: the catch scored the command-not-found as the intended failure and never reached Exit-SetupFailure. Pin the check to the EXIT-SETUP message. - test_windows_installer_concurrency_guard.py: the decision block prints before Exit-InstallFailure, so on Windows the active case aborted at exit 1 and never produced RESULT:blocked. - Studio.Setup.Vs2026.Tests.ps1: on a host without cmake, Ensure-BuildToolsForLlamaSourceBuild hits the sink first and the no-op case fails on the throw. Also stub the three remaining harnesses that splice sink-calling helpers but do not reach the sink on the paths they exercise today, so the next case added to them cannot reintroduce this. --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> |
