On Windows Server bots, an action whose\ncanonicalized output path contained a DOS-reserved basename (e.g.\n\"out/x/aux.out\") would fail IsLocal, propagate as Internal, and trigger\nup to 10x10 retries with exponential backoff — a 7-minute silent hang\nuntil CI\u0027s overall test timeout fired.\n\nThe check itself is correct: Kajiya needs to support running on\nWindows, where filepath.IsLocal()\u0027s reserved-name detection accurately\npredicts which paths it can later materialize on disk. The bug was the\ngRPC code we returned. Client-supplied input that the server can\u0027t\nhandle is codes.InvalidArgument, which Siso (and bazel\u0027s RemoteRetrier)\ncorrectly treat as non-retriable.\n\nIntroduce model.InvalidActionError, route every client-input validation\nfailure in LoadAction/addOutputsToTrie/treeToTrie through it, and have\nexecution.Service.Execute\u0027s deferred error handler errors.As it into\nstatus.Error(codes.InvalidArgument, ...) — following the same pattern\nalready in place for blobstore.MissingBlobsError -\u003e FailedPrecondition.\n\nStrengthen TestLoadAction_OutputErrorPropagates to assert the error\ntype, and add TestLoadAction_WindowsReservedOutputName as a regression\ntest (uses bare \"aux\" so it triggers IsLocal\u003dfalse on every Windows\nversion, including Win 11 where RtlIsDosDeviceName_U no longer flags\n\"aux.\u003cext\u003e\").\n\nBug: 514197708\nChange-Id: I980b30de8b53f76be11169ca38760e20e38a394c\nReviewed-on: https://chromium-review.googlesource.com/c/build/+/7852141\nCommit-Queue: Philipp Wollermann \u003cphilwo@google.com\u003e\nAuto-Submit: Philipp Wollermann \u003cphilwo@google.com\u003e\nReviewed-by: Fumitoshi Ukai \u003cukai@google.com\u003e\n" }, { "commit": "6c2dd7a620633492f6bf628afb65e72cc78f6b9a", "tree": "3d5f71cceee19e7ea9fc107c01e136c580424f8b", "parents": [ "3366c8bd07f7b7f3eab802cf3d859ff477c22391" ], "author": { "name": "Fumitoshi Ukai", "email": "ukai@google.com", "time": "Tue May 19 07:56:11 2026" }, "committer": { "name": "LUCI CQ", "email": "infra-scoped@luci-project-accounts.iam.gserviceaccount.com", "time": "Tue May 19 07:56:11 2026" }, "message": "siso: update docs for modifying with kajiya\n\nhttps://crrev.com/c/7850168 added `No-WithoutGoWork` footer\nto disable without go workspace in try, to make it possible\nto land API incompatible change without updating go.mod.\n\nExpected to update go.mod as soon as API incompatible change landed.\n\nChange-Id: I181c1cb565040599ef00429f8de811d430e480ca\nReviewed-on: https://chromium-review.googlesource.com/c/build/+/7858973\nReviewed-by: Takuto Ikuta \u003ctikuta@chromium.org\u003e\nCommit-Queue: Fumitoshi Ukai \u003cukai@google.com\u003e\nAuto-Submit: Fumitoshi Ukai \u003cukai@google.com\u003e\n" }, { "commit": "3366c8bd07f7b7f3eab802cf3d859ff477c22391", "tree": "867b7a879c2b0e4317a6e717cf45e21697a82787", "parents": [ "bcd29b6ed785f97513822e6279b823049074cb61" ], "author": { "name": "Philipp Wollermann", "email": "philwo@google.com", "time": "Tue May 19 07:42:14 2026" }, "committer": { "name": "LUCI CQ", "email": "infra-scoped@luci-project-accounts.iam.gserviceaccount.com", "time": "Tue May 19 07:42:14 2026" }, "message": "siso: bump Kajiya to latest version\n\nChange-Id: I392ddc6da3da4a255671c7d3caaf95b3448b0d98\nReviewed-on: https://chromium-review.googlesource.com/c/build/+/7806067\nAuto-Submit: Philipp Wollermann \u003cphilwo@google.com\u003e\nReviewed-by: Yuke Liao \u003cliaoyuke@google.com\u003e\nCommit-Queue: Philipp Wollermann \u003cphilwo@google.com\u003e\n" }, { "commit": "bcd29b6ed785f97513822e6279b823049074cb61", "tree": "f0d96bb21e4a0c7aa16334896945e979a9fa6d35", "parents": [ "05ca9d9b8a5b30c833d2eee330b9f71864111c86" ], "author": { "name": "Cole Faust", "email": "colefaust@google.com", "time": "Tue May 19 06:58:04 2026" }, "committer": { "name": "LUCI CQ", "email": "infra-scoped@luci-project-accounts.iam.gserviceaccount.com", "time": "Tue May 19 06:58:04 2026" }, "message": "Make sandbox depfile verification report all files\n\nPer a comment on crrev.com/c/7830283.\n\nBug: 475013705\nChange-Id: I964c42961a30c2de5a64d5e6d6522694f109d995\nReviewed-on: https://chromium-review.googlesource.com/c/build/+/7851345\nReviewed-by: Fumitoshi Ukai \u003cukai@google.com\u003e\nCommit-Queue: Cole Faust \u003ccolefaust@google.com\u003e\n" }, { "commit": "05ca9d9b8a5b30c833d2eee330b9f71864111c86", "tree": "1532f06faa1259e1ad9986ba8f6ef588639d895d", "parents": [ "94f3d794273b1d6ba8401c9e03b13323b84be31f" ], "author": { "name": "Philipp Wollermann", "email": "philwo@google.com", "time": "Tue May 19 06:28:35 2026" }, "committer": { "name": "LUCI CQ", "email": "infra-scoped@luci-project-accounts.iam.gserviceaccount.com", "time": "Tue May 19 06:28:35 2026" }, "message": "siso: drop unused checkout module from builtin mods\n\nThe Starlark `checkout` module (exposing `checkout.git.origin` from a\n`git ls-remote` lookup) has no consumers: no `.star` file in the siso\nrepo, in Chromium\u0027s `build/config/siso/`, or in any Chromium tree\nloads `@builtin//checkout.star`, references `__builtin_checkout`, or\nreads `.git.origin`.
