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.

Because surviving\nshared files retained the evicted label\u0027s bit in their mask,\nsurvivingMask always included the evicted bit, preventing\nactuallyEvictedMask from reclaiming dictionary slots. This caused\ntwo major defects:\n- Evicted build labels remained in hfs.buildLabelDictionary,\n causing them to permanently appear in ActiveBuildLabels() and\n --list_active_labels.\n- The 64-slot build label dictionary capacity was rapidly exhausted\n on multi-target builders, triggering continuous emergency LRU\n evictions.\n\nThis change fixes updateLedger to:\n- Remove successfully deleted files from hfs.fileBuildLabels.\n- Clear evicted label bits from surviving shared files in\n hfs.fileBuildLabels, while retaining bitmasks on files that failed\n or aborted deletion so Siso continues tracking them for subsequent\n GC runs.\n- Reclaim dictionary slots for evicted build labels that have no\n surviving files.\n- Mark the filesystem state as dirty so updates are persisted to disk.\n\nUnit tests are added to verify updateLedger bit stripping, dictionary\nreclamation, and aborted file tracking.\n\nBug: 446692498\nChange-Id:

was inconsistent, and also goes\nagainst the intention of RunTime being \"the total duration of the action\nexecution, including overhead such as uploading / downloading files\".\n\nA previous CL introduced a `-run` span for remoteexec, but it would have\nto overlap the last attempt + postproc.\nRather than trying to contort the last attempt to be parented to the\n`-run` span, let all the `-attempt` spans be siblings, have another\n`-postproc` sibling span.\n\nThen, the responsibility for deciding `-run` is pushed to where RunTime\nis projected.\n\nBug: b/520207778\nChange-Id:
