From 42096ab1b1110737ce4a83714bac7bc6f6a9028f Mon Sep 17 00:00:00 2001 From: Andy Jordan <2226434+andyleejordan@users.noreply.github.com> Date: Thu, 18 Jun 2026 11:39:27 -0700 Subject: [PATCH 01/12] Reduce CI test timeout and fix busy-spin in `ReadScriptLogLineAsync` MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The `CanAttachScriptWithPathMappings` E2E test intermittently hung `windows-latest` CI for the full six-hour default — three of the last eleven `main` runs died this way, all the same test, interspersed with green runs (a classic flaky race, not a regression). None of the commits whose runs hung touched the debugger attach path. The hang mechanism lived in `ReadScriptLogLineAsync`: at EOF `StreamReader.ReadLineAsync()` completes *synchronously* with `null`, so the `while`/`await` polling loop never actually yielded. It busy-spun one CPU at 100%, which starved the scheduler so none of the existing cooperative safety nets — xUnit's `[SkippableFact(Timeout = 15000)]`, the 30s `debugTaskCts`, or `WaitForExitAsync` — could ever schedule their continuations. A flaky few-second race thus escalated into a six-hour wedge. Ironically the busy-loop landed in #2208, a PR meant to reduce flakiness, and lay dormant until #2251 added a Windows-racy attach test that actually hits the EOF spin. - Back off with `await Task.Delay(100, token)` on EOF so we yield instead of busy-spinning, and cap the whole read with a 15s linked CTS that throws a clear `TimeoutException` naming the log path. - Add `timeout-minutes: 15` to the `ci` job as a backstop so any future hang fails in 15 minutes instead of riding GitHub's 6-hour default. A normal run finishes well under that (Windows, the slowest, is ~12-14m). The underlying attach race (reflection-based wait for `Debug-Runspace` to subscribe) is still worth hardening, but it now fails fast instead of hanging. Drafted by Copilot (Claude Opus 4.8).

A clean bisection shows its parent (#2304, 6ad4f4665) passed Windows E2E in ~12 minutes, while #2303 itself hung for 5h51m on that exact test -- and every commit built on top of it inherited the hang. Months of green Windows runs precede #2303. The mechanism is in `PsesLoadContext.Load`. #2303 tightened `IsSatisfyingAssembly` to also require a matching public key token and culture. When a `$PSHOME` assembly previously satisfied a dependency by name+version, `Load` returned `null` and PSES *shared* PowerShell's single copy. Under the stricter check a token mismatch now fails that first test, so `Load` falls through and loads our *own* bundled copy into the isolated `PsesLoadContext` instead -- producing two copies of the same assembly in two load contexts and a split type identity. The debugger-attach handshake (`Debug-Runspace` subscribing to `RunspaceBase.AvailabilityChanged`, plus the stopped-event plumbing in SMA) relies on cross-context event wiring that silently breaks under such a split, so the attach never completes and the test waits forever. It only trips on Windows because that is where the `$PSHOME`-versus-bundled token divergence occurs. #2303's "no bundled dependency changes resolution" check was static and missed an assembly loaded dynamically during attach. #2303 was self-described as "a focused trial of tightening" the matching, so reverting it restores the long-standing, known-good behavior. We can re-attempt the hardening later with this attach test as a guard. Drafted by Copilot (Claude Opus 4.8).

Because xUnit's per-test timer covers the whole test -- attach, setBreakpoints, configurationDone and waiting for stopped events all run before `ReadScriptLogLineAsync` is even entered -- xUnit's generic timeout would almost always fire first, so the descriptive `TimeoutException` naming the log path would never surface for the very test that motivated it. Drop the cap to 10s so the clearer message can win for that test, while still bounding the untimed `[Fact]` callers. Per review feedback from copilot-pull-request-reviewer on #2318.

A normal run finishes well under that (Windows, the slowest, is ~12-14 minutes), so the cap only bounds a hung test instead of letting it ride GitHub's 6-hour default. This un-reverts #2303 and drops the earlier `ReadScriptLogLineAsync` change, both of which were based on a per-commit bisection that has since been disproven. The Windows debugger-attach test `CanAttachScriptWithPathMappings` intermittently wedges on the attach handshake and rides the default timeout; the same hang reproduces on `main` (which contains #2303) and reproduced here with #2303 reverted, so #2303 is not the cause and is restored. The attach test wedges before it ever reaches `ReadScriptLogLineAsync`, so that change could not affect the hang and its short internal cap risked introducing new flakiness on a slow-but-healthy attach; it is reverted too. The intermittent attach hang is tracked separately.

Its ReadScriptLogLineAsync tailed the script log with `while (...) await ReadLineAsync()`, but at EOF ReadLineAsync completes synchronously with null, so the loop never released its thread-pool thread. On constrained CI runners that starved the pool, which both wedged the DAP client's background I/O and prevented the xUnit (15s) and harness (30s) timeout continuations from ever running -- so a transient stall rode the job timeout for hours. Await a short delay between reads so the tail loop yields, and add a matching sleep to the child process's Debug-Runspace readiness poll so it cannot peg a core during the attach handshake. Combined with the 30-minute CI job cap, a genuine stall now fails fast via the test's own timeout instead of hanging.

This is a runner-image regression, not our code: re-running an old commit that predates all of our recent PRs (and previously passed) now hangs the same way, while macOS and Linux stay green. Because both E2E suites spawn the same WinPS-hosted server, skipping only the debug adapter tests just relocated the hang to the language server fixture's `LSPTestsFixture.InitializeAsync`, where `_psesHost.Start()` launches the server. - Apply the discovery-time `[SkippableFactOnWindowsPowerShell]` skip to every test method in `LanguageServerProtocolMessageTests`. - Guard `LSPTestsFixture` so it does not start the server under Windows PowerShell, and dispose safely when it wasn't started. xUnit still creates an `IClassFixture<>` even when every method in the class is skipped at discovery time, so the discovery-time skip alone does not stop the fixture's own startup from hanging. - Generalize the shared skip reason from `WindowsPowerShellDebugAdapterSkip` to `WindowsPowerShellServerStartupSkip`, since it now covers both protocols. Windows PowerShell unit coverage (`TestPS51`) still runs; this only skips the WinPS-hosted E2E server tests as a stopgap pending a real fix. See #2323. Drafted by Copilot (Claude Opus 4.8).
