Stacked on #1004 (chore-buildkit-merge-v0.14.1). Merging this into #1004 turns #1004 into a slim BuildKit v0.14.1 upgrade. That upgrade drops #1004's image-export dedupe and keeps main's solve/export flow unchanged.

Why the dedupe goes

#1004 dedupes solves and exports because, against BuildKit v0.14.1, a RUN's output was printed 2–3× and tests/remote-cache failed. That turned out to be T10, not the export flow:

  • Every pllb.State.Marshal picked a fresh random LocalUniqueID, so each re-solve of a target got new digests with the same cache keys.
  • BuildKit then merged the edges, and since upstream e1da8b7f it replays the target's log history once per merge.

With T10 fixed (one local.unique per earth process), main's flow prints each RUN once.

The evidence is in the experiment, #1050 (draft, CI 72/72); the measurements are in its comment:

  • Duplicated output lines: 0 across 39 logs. That covers shared bases, COPY then RUN, inline cache, --global-wait-end, and 40 images in WAIT.
  • tests/remote-cache passes, locally and in CI.
  • Control: the same branch without the two T10 commits prints output twice, and tests/remote-cache fails (test '3' '-eq' '1').
  • --no-cache propagation (T8), BUILD --auto-skip and the multi-platform index are all correct.

The earlier round of this PR fixed bugs inside the dedupe (auto-skip, WAIT/END ordering, export predicates, a data race, starvation, multi-platform manifests, cross-block waits). Those bugs disappear with the dedupe. That work is kept on review/pr1004-export-ownership (old head 9dfd737) in case single-owner exports are wanted later.

Commits

Commit
3e3b2ee revert: drop #1004's export dedupe. earthfile2llb/wait_block.go and builder/builder.go go back to main. In converter.go the SkipBuilder move and isStateExported are removed, but #1004's mechanical BuildKit API changes stay (sourceresolver, dockerspec, Dockerfile2LLB). Only tests of removed code are removed (wait_block_test.go, TestIsMainHandledByImage).
8346181 test(pllb): marshaling the same state twice must give the same digests (red)
f1a8e9b fix(pllb): give every marshal this process's local.unique value (T10)
9e0293a chore(deps): bump buildkit to EarthBuild/buildkit#48 and fsutil to EarthBuild/fsutil#4
c475fcf chore(deps): re-pin buildkit to #48 head 1f6ea531, which carries the T8 fix (RUN --no-cache invalidates the commands after it again)
f6947eb fix(buildkitd): default update-buildkit to EarthBuild/buildkit main (earthly-main does not exist)
d34e232 test(cmd/earth): show installation-name fallbacks disagree (red)
0a80c03 fix(cmd/earth): fall back to the earth installation and binary name everywhere
0c75b90 fix(solvermon): report dropped runc stats under --debug (once per vertex)
f1e8334 style(solvermon): satisfy lint for the stats decode reporting

Both dependency pins point at unmerged stacked PRs. TODO comments in go.mod and buildkitd/Earthfile mark them to advance to the merged commits.

T10 in short

  • Fix: pllb.State.Marshal prepends llb.LocalUniqueID(processLocalUniqueID), one identity.NewID() per earth process. Repeated solves now load the same vertices, so nothing merges and nothing is replayed.
  • Why the daemon is unaffected: it never reads local.unique. The local source's cache key is the session ID plus include/exclude/follow patterns. Separate earth processes still get distinct IDs.
  • Override: a caller that sets llb.LocalUniqueID itself still wins; a test pins this.

The full reasoning is in the f1a8e9b commit message.

Not in this PR

main already exports a top-level --use-inline-cache image twice: once from the wait block and once from builder.go. This isn't a regression from the upgrade, so it is fixed separately in #1051, which is stacked on this one.

Verification

  • go build ./... passes. go test -race ./earthfile2llb/... ./builder/... ./logbus/... ./cmd/earth/... ./util/llbutil/... ./states/... passes.
  • earth +lint (with EARTH_CONFIG unset) passes.
  • Functional and CI results are on EXPERIMENT (do not merge): #1004 without export dedupe, on T8/T10 fixes #1050. Variant A there is this branch minus the installation-name and solvermon commits: CI 72/73, and the one failure is govulncheck, which also fails on main.

Walkthrough

This change centralizes image export planning and coordinates builder and wait-block exports with target completion. It also updates installation-name and BuildKit defaults, adds debug reporting for malformed solver stats, and assigns local-source identities during marshaling.

Changes

Image Export Planning

Layer / File(s) Summary
Image planning and builder integration
earthfile2llb/image_plan.go, earthfile2llb/earthfile2llb.go, builder/builder.go, builder/plan_image_test.go
PlanImage and SolvedByBuilder centralize image export and push decisions. The builder passes build-wide plan options to conversion and uses the plan for image handling and output summaries.
Wait-block export selection and snapshots
earthfile2llb/converter.go, earthfile2llb/wait_block.go, earthfile2llb/save_image_wait_item.go, earthfile2llb/*_test.go
Wait blocks snapshot items and select exports based on whether the block is top-level or detached. Image, artifact, and state handling use that snapshot. Tests cover inline-cache exports, push handling, state detection, and concurrent access.
Export completion and target status
states/export_outcome.go, states/states.go, earthfile2llb/converter.go, builder/builder.go, earthfile2llb/finalize_states_test.go
ExportOutcome coordinates export results and callbacks. Target completion follows the export that solves the main state, and the builder settles each target’s builder export with the build result.

Installation Name Defaults

Layer / File(s) Summary
Shared installation-name fallback
util/cliutil/earthdir.go, cmd/earth/flag/global.go, cmd/earth/common/shared.go, cmd/earth/main.go, cmd/earth/flag/installation_name_test.go
The CLI uses cliutil.DefaultInstallationName as the shared fallback. The flag usage and related documentation describe the installation-name directory, and tests check the fallback behavior.

BuildKit Defaults and Pins

Layer / File(s) Summary
BuildKit branch and revision defaults
Earthfile, buildkitd/Earthfile, go.mod
The default BuildKit branch changes to main. The default BuildKit base-image commit and BuildKit and fsutil replacement revisions are updated.

Solver Stats Decode Logging

Layer / File(s) Summary
Debug stats error reporting
logbus/setup/setup.go, logbus/solvermon/*
The debug flag is passed to SolverMonitor. In debug mode, vertex monitors report the first stats decode error for a vertex and continue to treat malformed stats packets as non-fatal.

Local Source Identity

Layer / File(s) Summary
Local-source identity during marshaling
util/llbutil/pllb/state.go, util/llbutil/pllb/state_test.go
Marshaling prepends a process-wide LocalUniqueID before caller-supplied constraints. Tests check stable repeated marshals and caller-supplied ID overrides.

Merge Risk: 🟡 Moderate · up to a3532

The new export coordination can, in some parallel BUILD orderings, leave a target without a completion status. Separately, runs with --debug may print registry or URL credentials contained in an operation name when a malformed stats packet arrives. Both fixes are small and should be made before merging.

Settle wait-block exports before the owning wait starts.

Parallel conversion starts BUILD processing asynchronously. Earthfile2LLB waits opt.waitBlock before it waits for the shared error group. An already visited target attaches its wait items only after sts.Done() returns. The block can therefore snapshot its items before the attachment.

A later Wait can short-circuit after called is set, so saveImages may never settle export.waitBlockItem.exported. FinalizeStates only chains endExecution to that result. The target can then miss its completion status.

Ensure that all parallel conversions attach their wait items before the owning block's first Wait. If that ordering is not guaranteed, settle items added after a completed wait or fall back to force execution.

Scrub the operation before writing the debug notice.

If an internal vertex operation contains URL credentials, a malformed stats packet writes those credentials to the generic log. The formatter can hide the vertex header without --verbose, but it displays generic output. Scrub operation before calling Generic().Write; the normal log-stream path already scrubs credentials.

Experiment, do not merge. Restores the solve/export flow of
earthfile2llb/converter.go, earthfile2llb/wait_block.go and
builder/builder.go to main (9c28bba), keeping #1004's mechanical
BuildKit API changes (sourceresolver.Opt, dockerspec types, the
Dockerfile2LLB signature).

Removed, as introduced by a62d7cb, 172db2e, 29355fa, 9e5859d,
6e725e8 and b38c06d:

* Converter.isStateExported and its use in FinalizeStates, so the async
  forced execution always runs again.
* waitBlock.isStateExported(Unlocked) and the waitStates skip.
* builder.go isMainHandledByImage, so the "main" ref is always solved.
* The SkipBuilder move before newSaveImage (and its GlobalWaitBlockFtr
  term) and the saveImages "!SkipBuilder" skip.

Tests for that removed code are removed with it:
earthfile2llb/wait_block_test.go (whole file) and TestIsMainHandledByImage
in builder/plan_image_test.go.

T10: RUN output after a COPY from the local build context is printed
three times although the RUN executes once.

One gateway job solves a target's main state up to three times (the
async forced execution in FinalizeStates, the wait block, and the
builder's main ref). Every pllb.State.Marshal goes through
llb.NewConstraints, which picks a fresh random LocalUniqueID, and local
sources without a session attribute embed it as local.unique. So each
marshal yields a different digest for the local source and everything
downstream of it (the COPY and the RUN), while their cache keys stay the
same. The scheduler merges the edges by cache key and replays the
target's log history into the job once per extra solve.

TestMarshalIsStableForLocalSources marshals a COPY-from-local then RUN
state twice and asserts identical definitions. It fails today.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
T10: RUN output after a COPY from the local build context was printed
once per solve of the target (three times) although the RUN ran once.

pllb.State.Marshal now prepends llb.LocalUniqueID(processLocalUniqueID),
a single identity.NewID() per earth process, so marshaling the same
state again yields the same digests for local sources and everything
downstream. The repeated solves (FinalizeStates' forced execution, the
wait block, the builder's main ref) then load the same vertices instead
of new ones that BuildKit merges by cache key and whose logs it replays
into the job via state.setEdge -> mpw.Add.

Why per process rather than per build or session:

- local.unique only exists to keep the client-side digest of a local
  source that has no local.session attribute from colliding with someone
  else's. The daemon never reads it: localSourceHandler's cache key is
  the session ID plus the include/exclude/follow patterns, and the
  provenance code strips it. Distinct earth processes on one daemon still
  get distinct IDs, so they never share a local-source vertex.
- One earth process runs one build. Its extra solves (the tar image
  solver for WITH DOCKER --load, the multi-image solver) use the same
  session attachables, so sharing their local-source vertices is
  harmless and saves work.
- Different local contexts don't collide: the source identifier is
  local://<absolute dir> and the attrs carry the include/exclude
  patterns and shared key hint, so the digest differs per context even
  with the same unique ID.
- No caller sets llb.LocalUniqueID today. The ID is prepended, so a
  caller that does still wins (later options override earlier ones);
  TestMarshalLetsCallersOverrideLocalUniqueID pins that. The WITH DOCKER
  tar context sets llb.SessionID and is unaffected.
- Nothing relied on the randomness to re-transfer files. Within a job the
  random digests already shared one cache key, so the scheduler merged
  them before any snapshot (that merge is the bug). File contents reach
  the cache via the COPY's content hash, not the source digest.
  --no-cache sets IgnoreCache on every solve of the build consistently
  (c.opt.NoCache, b.opt.NoCache), and BuildKit keys an ignore-cache load
  of an already active vertex separately (jobs.go dgstWithoutCache).
  LOCALLY doesn't use a local source. earth has no watch mode.

Turns TestMarshalIsStableForLocalSources green.

invalidates the commands after it. Still an unmerged stacked PR; the
existing TODOs cover advancing the pin once it lands.

#1004 switched the default BUILDKIT_GIT_ORG to EarthBuild but kept
BUILDKIT_GIT_BRANCH=earthly-main, a branch that only exists in the old
earthly fork. Without an explicit SHA the branch lookup came back empty
and +update-buildkit failed. EarthBuild/buildkit's default branch is
main.

RootFlags now falls back to the installation name "earth" (~/.earth).
cliutil.GetEarthDir still falls back to "earthly" (~/.earthly) for an
empty name, which is the name the autocomplete path passes before flags
are parsed. GetBinaryName also still falls back to "earthly" (this
predates the PR, and only applies when os.Args is empty).

Both tests are expected to fail.

… everywhere

#1004 changed RootFlags to fall back to the installation name "earth"
(~/.earth) when the binary is built without -X
main.DefaultInstallationName, i.e. with go build or go install. Two other
fallbacks still said "earthly":

* cliutil.GetEarthDir, used for an empty installation name. That
  happens on the autocomplete path, which runs before flags are parsed,
  so autocomplete wrote its logs to ~/.earthly while the rest of the CLI
  used ~/.earth.
* common.GetBinaryName, used when os.Args is empty. The installed
  binary is now earth.

Both now use "earth". The installation-name fallback is one exported
constant, cliutil.DefaultInstallationName, which RootFlags and
GetEarthDir share, so they cannot drift again.

Nothing else depends on the old default:
- Release and dev builds set DefaultInstallationName through ldflags
  (Earthfile: earth-dev by default).
- tests/cli builds its binary with
  -X main.DefaultInstallationName=earthly, so its ~/.earthly paths are
  unaffected.
- The earthly-named symlink and completion handling in bootstrap_cmds.go
  key off os.Executable(), not these fallbacks.

Doc comments that still said ~/.earthly now say ~/.<installation name>.

Turns TestInstallationNameFallbacksAgree and TestGetBinaryNameFallback
green.

#1004 made malformed stats packets non-fatal, but dropped them without
a trace. BuildKit's log size/rate limits can clip the binary stats
stream mid-frame, so occasional drops are expected; repeated ones would
signal a protocol mismatch and were invisible. With --debug, print one
notice per vertex naming the operation and the decode error.

Split stats handling out of vertexMonitor.Write (nestif), drop the now
unused nolint:nilerr, reorder struct fields for alignment, and fix wsl
and noinlineerr findings. No behaviour change.
