Pure refactor that prepares the exec command for the upcoming split between TUI and line-mode output paths. - shared/logger: rename isInteractiveTerminal -> IsInteractiveTerminal so it is usable from cli/exec. Two in-package callers updated. - shared/logger: add SetOutput for programmatic redirection of the zerolog global logger after SetupGlobalLogger has run. Returns a restore func. Intended for the TUI to route diagnostic log output into a ring buffer instead of stderr. - cli/exec/flags: add --no-tui (WOODPECKER_EXEC_NO_TUI).

Consumes the []*builder.Item produced by pipeline/frontend/builder and runs ready workflows in parallel respecting depends_on, up to a worker cap. The scheduler is not yet wired into runExec; that is chunk 3. This chunk only adds the package and its tests. Design notes: - Workflow-level events only (Pending/Ready/Running/Success/Failure/ Blocked/Canceled). Step-level tracing and log lines remain the responsibility of the pipeline runtime tracer/logger the caller configures inside RunFunc. This keeps the scheduler agnostic of rendering concerns and lets both the (upcoming) TUI and the line writer share the same scheduler. - No dependency on server/ code. A package-level comment flags the eventual refactor to unify with server/queue/fifo.go, but that is out of scope for this branch. - Worker cap: Options.Parallel defaults to runtime.NumCPU(); negative means unbounded. No cli flag yet. - Fail-fast is OFF: a failed workflow blocks its dependents but independent siblings keep running. This preserves the multierr behavior of the current sequential loop in runExec. - Context cancellation marks pending workflows Canceled, lets running ones drain through their own ctx, then returns the aggregate error. - Events channel is closed on return so consumers can use range. Tests cover linear ordering, parallel-cap saturation under race detection, transitive blocked propagation, fail-fast-off semantics, context cancel mid-run draining, multi-failure aggregation, empty input, and the defensive duplicate/unknown-dep validation (the builder normally strips these before the scheduler sees them).

Workflows now run concurrently where depends_on permits, bounded by runtime.NumCPU(). This is the observable behavior change of this chunk: independent workflows finish in parallel on line-mode output, matching what the scheduler already made possible. Line output contract (the grep-friendly stream on stderr): - Prefix is now '[step] line' for single-workflow runs, '[wf/step] line' for multi-workflow runs. The wf/ qualifier is necessary because interleaved parallel output is otherwise unattributable. - Dropped the 'Ln' line counter — redundant with the consumer's own line counting — and the elapsed-seconds suffix, which collides with zerolog's own timestamps when users pipe both streams together. - Prefix body is capped at 24 chars with an ellipsis, to stop long step names from pushing the log body off an 80-column terminal. - '# ' banner still emitted when a workflow starts running. The trigger is now a scheduler event (StateRunning) rather than the loop iterator, so banners appear in actual-start order and not in declaration order — matches what parallel execution produces. - Blocked and canceled workflows emit a short diagnostic line so the user understands why a workflow produced no step output. exec.go: - runExec now builds one pipelineCtx (timeout + SIGTERM) for the whole DAG instead of one per workflow. The scheduler hands each RunFunc invocation a child of this ctx so cancellation fans out. - Logger factory is per-workflow so the multi-workflow prefix is injected at LineWriter construction, not at each Write call. - Dropped the //nolint:contextcheck tag that covered the old sequential loop's ctx mismatch; no longer needed. - Removed the stale TODOs about parallelism and depends_on. Tests: - New cli/exec/line_test.go covers prefix format (single + multi workflow), truncation, missing-newline fix-up, Close no-op, and the '# name' banner contract. make test-cli, golangci-lint, and gofumpt are all clean. The TUI path is still not wired — --no-tui is inert; that comes in chunk 6. --- cli/exec/exec.go | 102 ++++++++++++++++++++++++++--------- cli/exec/line.go | 120 +++++++++++++++++++++++++++++++++++++----- cli/exec/line_test.go | 110 ++++++++++++++++++++++++++++++++++++++ 3 files changed, 295 insertions(+), 37 deletions(-) create mode 100644 cli/exec/line_test.go diff --git a/cli/exec/exec.go b/cli/exec/exec.go index f572ab0a173..e210520b46a 100644 --- a/cli/exec/exec.go +++ b/cli/exec/exec.go @@ -27,9 +27,9 @@ import ( "codeberg.org/6543/xyaml" "github.com/oklog/ulid/v2" "github.com/urfave/cli/v3" - "go.uber.org/multierr" "go.woodpecker-ci.org/woodpecker/v3/cli/common" + "go.woodpecker-ci.org/woodpecker/v3/cli/exec/scheduler" "go.woodpecker-ci.org/woodpecker/v3/cli/lint" "go.woodpecker-ci.org/woodpecker/v3/pipeline" "go.woodpecker-ci.org/woodpecker/v3/pipeline/backend" @@ -66,9 +66,7 @@ func run(ctx context.Context, c *cli.Command) error { return common.RunPipelineFunc(ctx, c, execFile, execDir) } -// TODO: do parallel runs with output to multiple _windows_ e.g. tmux like func execDir(ctx context.Context, c *cli.Command, dir string) error { - // TODO: respect pipeline dependency repoPath := c.String("repo-path") if repoPath != "" { repoPath, _ = filepath.Abs(repoPath) @@ -252,34 +250,93 @@ func runExec(ctx context.Context, c *cli.Command, yamls []*builder.YamlFile, rep return err } - var execErr error - // TODO: respect depends_on and run in parallel where possible - for _, item := range items { - fmt.Println("#", item.Workflow.Name) + // The pipeline context carries timeout + SIGTERM cancellation for + // the entire DAG run.

This chunk compiles and has unit-tested pure-logic pieces, but the package is not yet imported from runExec — the TUI mode stays inert until chunk 6 wires it in. Files: - ringbuf.go Ring is a FIFO line buffer with a byte cap and a truncation counter. Safe for one writer + one reader. Used per step for the log pane and once for the zerolog debug tab. - budget.go Budget tracks multiple rings against a shared cap and evicts oldest-from-largest-ring on Enforce. Constants GlobalLogCapBytes = 200 MiB for the shared step budget and DebugLogCapBytes = 5 MiB for the separate zerolog ring. - ringwriter.go io.Writer adapter that splits on newlines and appends to a Ring. Installed as the zerolog destination during TUI mode so stderr writes don't tear the alt-screen buffer. Buffers incomplete trailing fragments across Write calls and flushes on teardown. - messages.go tea.Msg types: WorkflowStateMsg, StepStateMsg, LogLineMsg, DebugTickMsg, PipelineDoneMsg, CancelingMsg. Data-only structs so model Update is unit-testable without a real pipeline. - model.go Model is the bubbletea Model. Seeded with workflow names; exposes DebugRing() and StepRing(workflow, uuid, name) so cli/exec can wire ring buffers without reaching into model internals. Update handles each message type; View returns a placeholderView for now so the program is runnable end-to-end. - styles.go Unicode status glyphs and placeholderView. The placeholder is deliberately prose so end-to-end wiring can be verified before committing to a lipgloss-based visual design in chunk 5. Tests: - ringbuf_test.go 14 cases: append within/over cap, eviction, oversized-line policy, unbounded cap, snapshot independence, concurrent write+read under -race; budget oldest-from-largest policy, zero cap inert, no-ring enforce; RingWriter newline splitting, cross-Write buffering, Flush with/without data. - model_test.go Lifecycle (pending → running → success → done), failure rendering, canceling state, step state + ring routing, unknown-workflow no-op, quit key. Deferred to chunk 5 and re-added there: Focus type, width/height/ focus fields, cursor, WindowSizeMsg handler — all dead weight in the skeleton, cleaner to introduce alongside the layout they actually serve. No new direct dependencies: bubbletea/v2, bubbles/v2, lipgloss/v2 were already indirect via huh/v2. Lint, vet, tests, and the full build-cli are all green. --- cli/exec/tui/budget.go | 106 +++++++++++++ cli/exec/tui/messages.go | 74 +++++++++ cli/exec/tui/model.go | 294 +++++++++++++++++++++++++++++++++++ cli/exec/tui/model_test.go | 178 +++++++++++++++++++++ cli/exec/tui/ringbuf.go | 118 ++++++++++++++ cli/exec/tui/ringbuf_test.go | 212 +++++++++++++++++++++++++ cli/exec/tui/ringwriter.go | 100 ++++++++++++ cli/exec/tui/styles.go | 112 +++++++++++++ 8 files changed, 1194 insertions(+) create mode 100644 cli/exec/tui/budget.go create mode 100644 cli/exec/tui/messages.go create mode 100644 cli/exec/tui/model.go create mode 100644 cli/exec/tui/model_test.go create mode 100644 cli/exec/tui/ringbuf.go create mode 100644 cli/exec/tui/ringbuf_test.go create mode 100644 cli/exec/tui/ringwriter.go create mode 100644 cli/exec/tui/styles.go diff --git a/cli/exec/tui/budget.go b/cli/exec/tui/budget.go new file mode 100644 index 00000000000..387d228878f --- /dev/null +++ b/cli/exec/tui/budget.go @@ -0,0 +1,106 @@ +// Copyright 2024 Woodpecker Authors +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. + +package tui + +import ( + "sync" +) + +// GlobalLogCapBytes is the TUI's shared memory budget for per-step +// log rings.

The tui package now renders a real interactive UI instead of the chunk-4 prose placeholder. It is still not wired into runExec — chunk 6 does that — so running the cli continues to produce line-mode output for now. Layout: - Left: workflow tree with per-step rows, status glyphs, expand/ collapse markers, and a cursor highlight when the tree has focus. - Right: tabbed pane (logs | debug). The log tab is backed by a bubbles/v2 viewport populated from the selected step's Ring; auto- scrolls to bottom only when already at bottom so scrolling back through history isn't snatched away by new lines. The debug tab is backed by a separate viewport sourced from the zerolog Ring. - Footer: focus indicator, N/M step counter, keybind hint. Switches to 'canceling…' / 'done' / 'failed' as the pipeline progresses. State / model changes: - Re-introduced the Focus enum (FocusTree / FocusLog / FocusDebug) and the UI state fields (width, height, cursor, focus, viewReady, logView, debugView) that chunk 4 deliberately omitted. The placeholder view in styles.go stays as the fallback before the first WindowSizeMsg arrives. - Update now handles WindowSizeMsg (propagates to both viewports + flags viewReady), refreshes the active pane on LogLineMsg / DebugTickMsg when the change is visible, and routes KeyPressMsg through a new focus-aware dispatcher. - Renamed CancellingMsg -> CancelingMsg to fix the misspell lint hit that survived chunk 4. New file view.go: - flatten() returns the navigable tree rows in render order — single source of truth used by cursor movement AND the renderer, so 'j' always moves the cursor to something the user sees. - layout() computes the pane widths (3/8 tree, 5/8 log, minimum 22 cols each) and reserves one row for the footer. - resizeViewports() recomputes bubbles viewport sizes on resize. - refreshLogView() / refreshDebugView() rebuild viewport content from the ring snapshots, prepending '[… N lines truncated]' when Ring has evicted anything. - Per plan §7b: lipgloss JoinHorizontal of tree+right, JoinVertical for body+footer. Unicode status glyphs from styles.go. Tree rows get a '›' selection prefix on top of the reverse-video style so focus survives themes without reverse support. New file view_test.go (12 cases) covers pane structure, cursor movement with bounds saturation, tab cycling through all three focus states, L jump to debug, selected-step log refresh vs unselected-step storage-only, progress counter transition, the canceling / failed footer states, and g/G top/bottom navigation. A plainView helper uses charmbracelet/x/ansi.Strip so assertions survive lipgloss's per-rune ANSI wrapping in styled output. Styling (styles.go): - Two colors from the 16-color ANSI palette: accent (cyan) for focused borders and active tabs; muted (bright black) for unfocused borders and inactive tabs. State-specific colors (success/failure/warning) will land with glyph coloring in the polish chunk. - paneStyle(focused bool) returns a rounded-border style with the border color swapped on focus. selectedRowStyle is reverse video so it works on any terminal. Named constants to satisfy mnd: paneBorderWidth, rightPaneTabsHeight, minTotalWidthMultiple, rowInnerPadding. shared/logger/logger.go: reworded two lines in the SetOutput docstring so godot is happy when the wider scope gets linted.

The existing line-mode path is unchanged for non-interactive invocations and for users who pass '--no-tui'; on an interactive terminal, the TUI takes over. exec.go changes: - Extract the scheduler-driving logic that existed inline in runExec into runLineMode, unchanged in behavior. The mode decision at the top of runExec is a single conditional: useTUI := !c.Bool("no-tui") && logger.IsInteractiveTerminal() - schedulerEventBuffer = 64 extracted as a named const. The buffer size mattered to lint (mnd) once it showed up in two call sites, and naming it lets the rationale live next to the value. New file exec_tui.go: - runTUIMode seeds a tui.Model with the workflow names from builder.Items, installs a RingWriter as the zerolog destination via logger.SetOutput so stderr writes do not tear the alt-screen, builds a tea.Program, and starts four cooperating goroutines: 1. signal handler — two-stage sigint. First signal cancels the run context and Sends CancelingMsg so the model flips its footer. Second signal os.Exit(130), abandoning the alt-screen (the terminal restores on process exit). 2. scheduler events drainer — forwards each scheduler.Event to p.Send(WorkflowStateMsg{Event: ev}). 3. scheduler.Run — executes the DAG; Sends PipelineDoneMsg when it returns so the model can transition to its final state. 4. the tea event loop (main goroutine via p.Run). - tuiRunFunc builds a per-workflow tracer that chains tracing.DefaultTracer (so env vars still populate) with a prog.Send of StepStateMsg, and a per-workflow logger that hands CopyLineByLine a tuiStepWriter which forwards each line as LogLineMsg. No stderr writes on this path; the tui owns the display. - tuiStepWriter is a trivial io.Writer that packages bytes into a LogLineMsg. Write returns len(p) per the io.Writer contract so upstream accounting stays correct. Close is a no-op. - flushDebugRingToStderr runs after the alt-screen is gone and dumps any accumulated zerolog output back to stderr, prefixed with a truncation marker if the ring evicted anything. This preserves diagnostics that would otherwise vanish with the buffer. tui/model.go: - View now sets v.AltScreen = true, which is how bubbletea v2 enables the alternate screen buffer (the v1 tea.WithAltScreen option no longer exists). This is the only semantic change to the tui package in this chunk; it doesn't affect tests because they access .Content. Constants added: sigintExitCode = 130, sigChanBuffer = 2. context.WithCancel is used inside runTUIMode to layer an explicit cancel on top of pipelineCtx; it gets a //nolint:forbidigo with a rationale because the two-stage sigint handler needs to cancel independently from the outer timeout.

Previously Init returned nil, which meant DebugTickMsg was defined and handled but nothing ever produced one — the budget Enforce and the debug pane refresh simply never fired at runtime. - The DebugTickMsg handler now re-arms itself with tickDebug(), so once the loop starts it runs until tea.Quit. Interval is 250ms, chosen as a named const (debugTickInterval) — fast enough that fresh zerolog lines appear interactively, slow enough that the budget scan is cheap. - tickDebug() is a tea.Tick helper shared by Init and the handler. Two new tests pin the contract: TestModelInitSchedulesDebugTick verifies Init's returned cmd produces a DebugTickMsg; TestModelDebugTickReschedules verifies the handler's cmd also produces one. Without these, a misrefactor that breaks the loop could land without visible failure. exec_tui.go: - The deferred cleanup block now flushes the debug ring to stderr in addition to restoring the logger. Previously flushDebugRing ToStderr ran only on the happy path, at the bottom of the function; if prog.Run panicked — or if any of the surrounding setup did — the zerolog output accumulated during the session was silently lost along with the alt-screen buffer. The defer body documents the ordering: restore the logger first so any log calls that happen during the flush itself go to real stderr rather than back into the ring we're draining; then flush the RingWriter's carried-over fragment; then dump the ring to stderr.

The same workflows running sequentially (before chunk 3) never hit this — each finished its teardown before the next started. Root cause: cli/exec/exec.go built a single prefix with prefix := "wp_" + ulid.Make().String() and passed it into compiler.WithPrefix(prefix), making it the prefix for every workflow the builder compiled in that run. The compiler derives each workflow's network and volume name from the prefix as "%s_default" so all workflows ended up with identical docker resource names. The pipeline builder (pipeline/frontend/builder/builder.go:220-226) ALREADY generates a unique per-workflow prefix of the form wp__ but the CLI's "caller options win" post-append in the builder (line 231-233) meant the CLI's shared prefix clobbered the per-workflow one. Fix: 1. Remove compiler.WithPrefix from CompilerOptions. The builder's per-workflow prefix now wins, and each workflow's Config.Volume and Config.Network become genuinely unique. 2. The CLI's local-mode workspace volume mount "_default:" used to be added via compiler.WithVolumes(...), which applied globally. With per-workflow prefixes, the global injection point no longer exists, so we inject the mount after the build, walking each item's compiled Config and appending to every step's Volumes. 3. The non-local workspace mount is already handled per-workflow inside the compiler (convert.go:82), so that path needs no changes. New file cli/exec/exec_workspace_test.go pins the behavior: per-workflow mount isolation, every step across every stage gets the mount, appending to existing Volumes not replacing them, safe handling of items with nil Config or empty Volume, and multi-stage workflows. This is the bug the smoke test caught after shipping chunk 7 — sequential execution hid it for years; the scheduler exposed it on its first real parallel run. --- cli/exec/exec.go | 83 ++++++++++++++---- cli/exec/exec_workspace_test.go | 145 ++++++++++++++++++++++++++++++++ 2 files changed, 210 insertions(+), 18 deletions(-) create mode 100644 cli/exec/exec_workspace_test.go diff --git a/cli/exec/exec.go b/cli/exec/exec.go index 70ee60e1a3e..fea6bcaa731 100644 --- a/cli/exec/exec.go +++ b/cli/exec/exec.go @@ -25,7 +25,6 @@ import ( "strings" "codeberg.org/6543/xyaml" - "github.com/oklog/ulid/v2" "github.com/urfave/cli/v3" "go.woodpecker-ci.org/woodpecker/v3/cli/common" @@ -151,14 +150,19 @@ func runExec(ctx context.Context, c *cli.Command, yamls []*builder.YamlFile, rep privilegedPlugins := c.StringSlice("plugins-privileged") - // emulate server prefix for volume/network naming - prefix := "wp_" + ulid.Make().String() + // NOTE: we deliberately do NOT set compiler.WithPrefix here. + // The pipeline builder (pipeline/frontend/builder) generates a + // unique prefix per workflow of the form wp__, + // which becomes the workflow's docker network and volume name. + // Passing a shared WithPrefix would override that per-workflow + // value and cause parallel workflows to collide on the same + // docker network/volume — the exact symptom that appeared when + // the scheduler started running workflows concurrently. // build compiler options — mirrors server behavior compilerOpts := []compiler.Option{ compiler.WithEscalated(privilegedPlugins...), compiler.WithNetworks(c.StringSlice("network")...), - compiler.WithPrefix(prefix), compiler.WithProxy(compiler.ProxyOptions{ NoProxy: c.String("backend-no-proxy"), HTTPProxy: c.String("backend-http-proxy"), @@ -176,24 +180,22 @@ func runExec(ctx context.Context, c *cli.Command, yamls []*builder.YamlFile, rep // configure volumes for local execution volumes := c.StringSlice("volumes") + compilerOpts = append(compilerOpts, + compiler.WithWorkspace( + c.String("workspace-base"), + c.String("workspace-path"), + ), + ) if c.Bool("local") { - compilerOpts = append(compilerOpts, - compiler.WithWorkspace( - c.String("workspace-base"), - c.String("workspace-path"), - ), - ) + // In local mode we bind-mount the user's repo directory into + // each step so the step sees the working tree as-is instead + // of a cloned copy.

On an interactive tty, that text sat in the scrollback for a few milliseconds before the alt-screen buffer wiped it on TUI startup. Users who needed to see the warnings had to either quit the TUI to check the scrollback, or re-run with --no-tui. The TUI's earlier split-pane layout also had a 'debug' tab in the right pane that carried the same mental-model: zerolog diagnostics that were neither step output nor tree state. In practice the two categories of content (pre-run warnings vs runtime diagnostics) are the same thing: everything-else. This change merges them. Layout change: before after ┌──────┬───────────────┐ ┌──────┬────────────────┐ │ tree │ log │ debug │ │ tree │ log │ │ │ (tabbed) │ │ │ │ └──────┴───────────────┘ ├──────┴────────────────┤ │ messages │ └───────────────────────┘ The right pane is now dedicated to step log output only. A new full-width 'messages' strip sits below the top row and above the keybind footer, with defaultMessagesHeight = 8 rows (clamped against minTopRowHeight = 6 and minMessagesHeight = 3 on tight terminals). cli/exec/exec.go: - The useTUI decision moves up ahead of the lint-warning print site. In TUI mode the warning text is captured into a strings.Builder and passed to runTUIMode as a new preRunMessages parameter instead of hitting stdout. Line mode keeps printing to stdout exactly as before — the output contract for CI logs is unchanged. cli/exec/exec_tui.go: - runTUIMode takes the new preRunMessages string. Each line is appended to the model's messages ring via strings.SplitAfter so trailing newlines are preserved. Zerolog's RingWriter is still installed into the same ring, so the pane seamlessly transitions from pre-run seed lines to runtime diagnostics with no visual split. cli/exec/tui/: - view.go: new layout() returns four values (tree width, log width, top-row height, messages height). resizeViewports sizes both bubbles viewports accordingly. renderView composes JoinHorizontal(tree, logPane) over messagesPane over footer. renderRightPane + renderTabs replaced by renderLogPane and renderMessagesPane. The log pane title annotates with the selected 'logs: /' so the user knows what they're reading without cross-referencing the tree cursor. - styles.go: tabInactiveStyle dropped (no more tabs). Renamed tabActiveStyle -> paneTitleStyle to match its new role. - model.go: Focus enum: FocusDebug -> FocusMessages. Field renames m.debug -> m.messages, m.debugView -> m.messagesView, refreshDebugView -> refreshMessagesView. DebugRing() -> MessagesRing() on the public surface. DebugLogCapBytes -> MessagesLogCapBytes. DebugTickMsg kept (still drives refreshes, name describes the role not the pane). - Layout constants added: defaultMessagesHeight = 8, minTopRowHeight = 6, minMessagesHeight = 3, paneBorderHeight = 2. Obsolete rightPaneTabsHeight removed. - L keybind still jumps to the messages pane (previously 'debug'). Footer shows [tree] / [log] / [messages]. Tests: - view_test.go: existing 'right-pane tabs must render' assertion becomes 'messages pane must render' on the word 'messages'. TestDebugKeyJumpsToDebugPane renamed to TestLKeyJumpsToMessages Pane with the footer assertion updated to '[messages]'. New TestPreRunMessagesAppearInMessagesPane seeds the ring with two lint-warning lines, drives the WindowSizeMsg + DebugTickMsg sequence, and asserts both lines appear in the rendered frame.

Pending steps were invisible until they began executing, so the tree effectively showed 'running' and 'finished' steps but never 'what's coming next'. This change pre-seeds the model with the compiled step list for each workflow so every step is visible from the moment the TUI starts, with a pending glyph (·). Each step then visibly transitions through pending → running (●) → success (✓) / failure (✗) / skipped (⊘) as the pipeline executes — giving the user a real-time picture of the plan and its progress instead of pop-ins at each step start. cli/exec/tui/model.go: - New NewFromSeeds constructor takes []WorkflowSeed, each with a Name and a []StepSeed describing the steps the workflow will run. Seeds a stepNode with a log ring per step, registered with the global budget, in StatePending visually. - The bare New(workflowNames) constructor is preserved as a thin wrapper over NewFromSeeds for tests that don't care about steps. - WorkflowSeed and StepSeed are tui-local types, not pass-through of builder.Item — keeps the tui package from depending on the builder and lets tests build fixtures without constructing a full backend_types.Config. - stepNode grows a 'started' bool. It flips true the first time a tracer event reports Started != 0, distinguishing pending from running (both have Exited=false). - handleStepState and StepRing now go through a shared findOrCreateStep helper that matches by UUID first, then by name, then (defensively) creates a new node. The seeded-UUID happy path means production runs never create duplicates; the name fallback keeps tests that use the bare New() constructor working; the create fallback covers unknown steps that might sneak in from future runtime sources. cli/exec/tui/view.go: - stepGlyph now returns glyphPending (·) when neither terminal states nor started are set. Ordering in the switch: terminal first (skipped/success/failure/oomKill), then started (running), then fallback (pending) — so a brief terminal-state-without- started-flip doesn't flicker back through pending. cli/exec/tui/styles.go: - The placeholder view's ad-hoc step glyph logic replaced with a call to stepGlyph so pre-WindowSizeMsg renders match the full layout's treatment. cli/exec/exec_tui.go: - runTUIMode now builds []tui.WorkflowSeed from each item's Config.Stages[].Steps[] and calls tui.NewFromSeeds instead of passing just workflow names. Empty or nil Config is handled gracefully (the workflow still seeds with no steps, matching the pre-change behavior for that edge case). Tests (cli/exec/tui/view_test.go): - TestSeededStepsAppearAsPendingBeforeRunning: three seeded steps all render in the tree with no running/success/failure glyphs present — they're all pending. - TestStepTransitionsPendingToRunningToSuccess: walks a single step through pending → running (Started=, Exited=false) → success (Exited, ExitCode=0), asserting the correct glyph at each stage. - TestStepSeededByUUIDDoesNotDuplicate: seed a step, then send a tracer event with the same UUID; verify the step name appears exactly once in the tree region (no duplicate row from the lookup-by-uuid path missing the seed). Verification: gofumpt clean, vet clean, golangci-lint 0 issues, all tui tests (34/34) pass under -race, full cli/exec tests pass, build-cli green, line-mode smoke still prints warnings to stdout unchanged. --- cli/exec/exec_tui.go | 23 ++++- cli/exec/tui/model.go | 192 +++++++++++++++++++++++++++++--------- cli/exec/tui/styles.go | 13 +-- cli/exec/tui/view.go | 10 +- cli/exec/tui/view_test.go | 123 +++++++++++++++++++++++- 5 files changed, 296 insertions(+), 65 deletions(-) diff --git a/cli/exec/exec_tui.go b/cli/exec/exec_tui.go index 7186a8ab809..b89fb7ae0d1 100644 --- a/cli/exec/exec_tui.go +++ b/cli/exec/exec_tui.go @@ -77,12 +77,27 @@ func runTUIMode(pipelineCtx context.Context, items []*builder.Item, backendEngin runCtx, cancel := context.WithCancel(pipelineCtx) //nolint:forbidigo // needed for two-stage sigint defer cancel() - // Seed the model with workflow names. - workflowNames := make([]string, len(items)) + // Seed the model with each workflow's full step list from the + // compiled backend config so every step appears in the tree with + // a 'pending' glyph before the scheduler starts.
