steps\n\n1. Fix frozen duration display during wait phases:\n formatStepRow displayed servDuration(), which excludes wait time\n (time.Since(startTime) - WaitDuration()). During wait phases such as\n wait-local, elapsed time increased while wait duration also increased\n in real-time, cancelling each other out and causing the displayed duration\n to remain frozen/stagnant.\n Fix this by introducing Step.displayDuration(), which reports the time\n spent in the current wait phase (time.Since(waitStart)) while waiting,\n and switches back to servDuration() during running phases.\n\n2. Unify wait phase handling and fix missing stepCacheWriteWait in\nSetPhase:\n Define phaseWaitPairs to share wait phase definitions across wait() and\n isWait(), avoiding definition drift. Also update stepState.SetPhase to\n use phase.isWait(), fixing a bug where stepCacheWriteWait was missed.\n\n3. Prioritize running steps in progress UI:\n topActives previously selected the 5 oldest active steps by startTime.\n Since running steps that acquire semaphores finish quickly and leave\n actives upon Done(), lower-priority waiting steps deferred by the\n prioritized semaphore remain and accumulate as the oldest active steps,\n filling all 5 slots and hiding active running steps from the UI.\n Fix this by prioritizing running (non-wait) steps over waiting steps via\n stepActiveLess when selecting and sorting topActives.\n\nBug: 519018985\nChange-Id: I76d5787c91351f0f0d97888209a6d3e1179beb0f\nReviewed-on: https://chromium-review.googlesource.com/c/build/+/8281427\nReviewed-by: Richard Wang \u003crichardwa@google.com\u003e\nCommit-Queue: Takuto Ikuta \u003ctikuta@chromium.org\u003e\n" }, { "commit": "a6cfb4bbf02e904a988e2d01c32deacf4e7e39f4", "tree": "539ae496201873ee17b52be370f6aa92f90822bd", "parents": [ "2a628344f1ce5cc4cf5e92f2b3d49f18fd67eddd" ], "author": { "name": "Fumitoshi Ukai", "email": "ukai@google.com", "time": "Tue Aug 25 05:39:24 2026" }, "committer": { "name": "LUCI CQ", "email": "infra-scoped@luci-project-accounts.iam.gserviceaccount.com", "time": "Tue Aug 25 05:39:24 2026" }, "message": "siso: return context error from Handle\n\nwhen context is canceled during handler,\nhandler would return error that wraps\n\"rpc error: code \u003d Canceled desc \u003d context canceled\",\nwhich is not context.Canceled,\nso it would be printed as step error.\ne.g.\nhttps://ci.chromium.org/ui/p/chromium/builders/build/linux-chromeos-build-perf-siso/21770/overview\n```\nfailed to run handler for 8687bf1d-2fd5-48cc-b020-8d120617598d: failed to run webui_eslint_ts[@config//typescript_all.star:245:1:_webui_eslint_ts]: readfile out/6ae0-linux-chromeos-/gen/ash/webui/color_internals/resources/tsconfig_build_ts.json: rpc error: code \u003d Canceled desc \u003d context canceled\n```\n\nwhen ctx is done when handler function returned error,\nreturn error that wraps context.Canceled.\n\nChange-Id: I6a0e87f80f603f9dd41913d78efb030ad5865740\nReviewed-on: https://chromium-review.googlesource.com/c/build/+/8285321\nAuto-Submit: Fumitoshi Ukai \u003cukai@google.com\u003e\nReviewed-by: Yuke Liao \u003cliaoyuke@google.com\u003e\nCommit-Queue: Yuke Liao \u003cliaoyuke@google.com\u003e\n" }, { "commit": "2a628344f1ce5cc4cf5e92f2b3d49f18fd67eddd", "tree": "da511f98fd04e3b28170c29ea40443eed7cdebce", "parents": [ "da6dab06f07af293f3695730868206f97c257661" ], "author": { "name": "Fumitoshi Ukai", "email": "ukai@google.com", "time": "Mon Aug 24 05:00:40 2026" }, "committer": { "name": "LUCI CQ", "email": "infra-scoped@luci-project-accounts.iam.gserviceaccount.com", "time": "Mon Aug 24 05:00:40 2026" }, "message": "siso: update version string to v1.5.30\n\nv1.5.29 is rolled out as pinned version at\ngit_revision:da6dab06f07af293f3695730868206f97c257661\nhttps://crrev.com/c/8282696\nhttp://ag/41701460\n\nBug: b/548182580\nChange-Id: I007c5b82aca1c98b41386b93526191d03819bfe1\nReviewed-on: https://chromium-review.googlesource.com/c/build/+/8284420\nReviewed-by: Neri Marschik \u003cnerima@google.com\u003e\nReviewed-by: Yuke Liao \u003cliaoyuke@google.com\u003e\nCommit-Queue: Fumitoshi Ukai \u003cukai@google.com\u003e\n" }, { "commit": "da6dab06f07af293f3695730868206f97c257661", "tree": "066d2eeed4bb4fde610b7c855b98f425315a5c70", "parents": [ "29aa3f7c0496d47b10421da1568202a4c15c4bd4" ], "author": { "name": "Junji Watanabe", "email": "jwata@google.com", "time": "Fri Aug 21 06:55:11 2026" }, "committer": { "name": "LUCI CQ", "email": "infra-scoped@luci-project-accounts.iam.gserviceaccount.com", "time": "Fri Aug 21 06:55:11 2026" }, "message": "siso: disable compression in walkdir\n\nDirectory messages usually reside in Spanner inline storage (\u003c 1MiB) and\nare stored as uncompressed plaintext.
