* feat: add selfApproval option to WAC waitForApproval + inline approval buttons
Add self-approval configuration to WAC workflows and inline
approve/reject buttons in WorkflowTimeline.
- TS SDK: add selfApproval option to waitForApproval()
- Python SDK: add self_approval param to wait_for_approval()
- Backend: store approval_conditions in flow_status for WAC,
enforce self-approval checks on resume endpoints
- Frontend: show Approve/Reject buttons in timeline with form
support (EE), gated by user permissions
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: revert sqlx query change + regenerate system prompts
- Revert get_suspended_flow_info to use original sqlx::query_as!
with COALESCE to avoid sqlx offline cache mismatch in CI
- Detect WAC by checking if FlowStatus parsing fails + suspend > 0
- Re-fetch flow_status column separately for WAC approval conditions
- Regenerate auto-generated system prompt files for SDK changes
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: use resume URLs for WAC inline approval buttons
- Backend generates HMAC-signed resume/cancel URLs when creating
WAC approval, stores them in timeline entry and approval meta
- Frontend uses anonymous resume endpoint (like classic flows)
with fallback to resumeSuspendedFlowAsOwner for admins
- Buttons show for everyone when URLs are present; server-side
self_approval_disabled check enforces restrictions
- Show warning for admins/owners when self-approval is disabled
- selfApproval: false requires EE (errors at dispatch on CE)
- self_approval_disabled check moved outside user_auth_required
gate so it works independently
- WAC detection no longer requires task import
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add resume_suspended and approval_info endpoints
- New approval_token DB table for token-based approval access
- New POST /jobs_u/flow/resume_suspended/{job_id} endpoint:
- OptAuthed: works with login or approval_token
- Checks approval_conditions (self_approval, groups, auth)
- Admins/owners bypass rules
- New GET /jobs_u/flow/approval_info/{job_id} endpoint:
- Returns form, rules, can_approve status
- HMAC anonymous endpoint now bypasses all approval_conditions
(secret = full capability)
- getResumeUrls approvalPage URL now uses token format
- WAC approval dispatch generates and stores approval tokens
- Mark resumeSuspendedFlowAsOwner as legacy
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: simplify frontend to use resume_suspended endpoint
- OpenAPI spec updated with resume_suspended and approval_info endpoints
- WorkflowTimeline: removed URL parsing, now calls single
resumeSuspended endpoint for both approve and reject
- Buttons show for any logged-in user viewing the job (backend
enforces authorization rules)
- Kept self-approval warning for admins
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: stateless approval tokens, new approval page, FlowStatusWaitingForEvents update
- Replace DB-stored approval tokens with stateless HMAC derivation:
token = HMAC(workspace_key, job_id + "approval_token")
Verifiable without DB lookup, not reversible to resume secret
- Drop approval_token migration (no DB table needed)
- FlowStatusWaitingForEvents: use resumeSuspended endpoint instead
of URL parsing + resumeSuspendedFlowAsOwner
- New approval page route /approve/{ws}/{job}?token= that uses
approval_info and resume_suspended endpoints
- Old approval page route kept for back-compat
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: match old approval page content in new approval page
- Add FlowMetadata, JobArgs, FlowGraphV2, DisplayResult
- Add approvers with tooltips, flow arguments section
- Add admin self-approval bypass warning
- Add "Open run details" link
- Fetch full job alongside approval_info for all UI data
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: filter _MODULES from args, show 'workflow' for WAC approvals
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* chore: remove deno template from approval/prompt SuspendDrawer
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: approval page form display + hide deno from approval script picker
- Fix form schema rendering on new approval page by wrapping flat
WAC form schemas in { properties, order } for SchemaForm
- Hide deno from the approval step language picker in flow editor
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: remove deno from canHaveApproval in script_helpers.ts
The insert menu uses canHaveApproval() from script_helpers.ts via
FlowInputsQuick, not the displayLang function in FlowInputs.svelte.
Revert the unnecessary FlowInputs.svelte change.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: return form schema and description in approval_info for classic flows
The approval_info endpoint was returning None for form_schema on
classic flows. Now fetches raw_flow to get suspend.resume_form
schema, hide_cancel, and the step's completed result for description.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: inline Login component on approval page instead of redirect
Show the Login component directly on the approval page when
authentication is required. On successful login, reloads user
and approval info without navigating away.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: show resume buttons for all users, not just owners
The resume_suspended endpoint handles authorization server-side,
so the frontend should always show the buttons. Remove isOwner
gate and the "cannot resume" message.

* fix: prevent layout shift on resume by removing spinner from cancel button
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: prevent resume button expansion by using disabled instead of loading
The loading prop adds a Loader2 spinner that expands the button width.
Use disabled={loading} instead to prevent layout shift.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: approval page login redirects back with full page reload
Set rd to the full URL (starts with http) so Login.redirectUser()
uses window.location.href instead of goto(), triggering a full page
reload after login. This ensures the approval page re-fetches data
as an authenticated user.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: fetch flow definition from flow_version when raw_flow is null
Deployed flows don't store raw_flow on the job. Fall back to
flow_version table using runnable_id to get suspend settings
(form schema, hide_cancel) for the approval_info endpoint.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: show specific reasons when user cannot approve
Display whether denial is due to self-approval being disabled,
required group membership, or both.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: support both nested and flat form schema in waitForApproval
Users can now pass either:
waitForApproval({ form: { schema: { name: { type: "string" } } } })
or:
waitForApproval({ form: { name: { type: "string" } } })
Both WorkflowTimeline and approval page handle both formats.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: convert sqlx query macros to non-macro for CI offline cache
Replace sqlx::query! and sqlx::query_scalar! with sqlx::query and
sqlx::query_as to avoid SQLX_OFFLINE cache misses in CI.
Also remove unused LogIn import from approval page.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: suppress dead code warning + unused isOwner variable
- Add #[allow(dead_code)] to without_flow method (CI -D warnings)
- Rename isOwner to _isOwner in FlowStatusWaitingForEvents (unused)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: security and robustness fixes from PR review
- Add workspace_id verification in resume_suspended to prevent
cross-workspace approval (#3)
- Fix token leakage: use relative path for login redirect instead
of full URL with token (#4)
- Handle getJob failure independently from approval_info so the
page works for unauthenticated users (#7)
- Clear error state on successful data load (#13)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: address review feedback — shared token gen, rand resume_id, UX
- Move generate_approval_token to windmill-common::variables (shared
between windmill-api and windmill-worker, eliminates duplicate HMAC)
- Use rand::random::<u32>() for resume_id instead of DefaultHasher
- Stop polling after approve/reject on approval page
- Add cancelLoading state to WorkflowTimeline Reject button

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* sqlx
* feat: enrich WAC templates with checkpoint and replay semantics
Add prominent comments explaining that all computation must happen
inside task/step/taskScript or it will be replayed on resume/retry.
Clarify that waitForApproval does not hold a worker and that
approve/reject URLs are available in the timeline step details.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix(cli): script module sync idempotency, per-module hash tracking, and preview support
- Fix pull→push idempotency: use `??` instead of `||` for module lock
field so empty strings are preserved (matches API's `lock: ""`)
- Add per-module hash tracking in wmill-lock.yaml following the flow
inline script pattern (SCRIPT_TOP_HASH + per-module subpath hashes)
- Selective module lock regeneration: only regenerate locks for modules
whose content actually changed, not all modules
- Use unfiltered rawWorkspaceDependencies for module hashes to match
what updateModuleLocks passes to fetchScriptLock
- Show changed module names in stale script output for clarity
- Add module support to `script preview` command: read modules from
__mod/ folder and pass them in the preview API request
- Add preview tests for taskScript pattern (flat and folder layout)
- Update test assertion for module stale detection output
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(frontend): WAC UI improvements — reorder templates, module tab rename, import consolidation
- Reorder WAC template buttons: TypeScript before Python in
ScriptBuilder, CreateActionsScript, and CreateActionsFlow
- Remove dropdown items from +Script button (simplify to direct link)
- Move "Import Workflow-as-Code" to +Flow dropdown with dedicated drawer
- Add module tab rename: pencil icon on hover opens popover with
validation, fixed-width icon container prevents layout shift
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: remaining module-mode changes from working branch
- Backend parser updates for WAC detection
- CLI sync/types updates for raw app path and module support
- Frontend UI polish (Dev.svelte, ScriptRow, script hash page)
- Test fixture updates
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test(cli): add test for module modification detection in generate-metadata
Verifies that modifying a single module file re-triggers stale
detection and only the changed module is listed, not all modules.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(backend): critical fixes from PR review
- Fix hardcoded dev path in bun_executor.rs WAC v2 wrapper — use
"windmill-client" import instead of absolute filesystem path
- Fix missed no_main_func → auto_kind rename in parser TS test
- Add modules column to clone_script SQL (windmill-common and
windmill-api-workspaces) so cloned scripts retain their modules
- Add modules: None to RawCode structs in worker tests
- Restore complete sqlx cache (merge main's cache + our new queries)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(backend): fix clone warning treated as error in CI
Change `.clone()` on double reference to `*k` dereference in
scripts.rs hash implementation. Update sqlx cache with new query
hashes from modified clone_script SQL.

* fix(frontend): use published parser wasm versions for CI build
The local file:// paths for windmill-parser-wasm-py and
windmill-parser-wasm-ts don't exist in the Cloudflare Pages build
environment. Revert to published npm versions (1.655.0).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(frontend): update parser wasm packages to 1.657.2
Use newly published windmill-parser-wasm-ts and windmill-parser-wasm-py
v1.657.2 which include auto_kind/WAC detection changes.

* fix(frontend): regenerate package-lock.json for npm ci compatibility
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(frontend): use main's lockfile as base, update only parser wasm packages
Regenerating package-lock.json from scratch pulled different dependency
versions causing svelte-check type errors. Instead, start from main's
lockfile and only update the two changed packages.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(backend): add modules column to fetch_script_for_update query
The Script<SR> struct has a modules field (FromRow), but
fetch_script_for_update didn't SELECT modules, causing a runtime
error "no column found for name: modules" when the worker processed
dependency jobs. This was the root cause of the relock_skip test
timeout.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(backend): fix script module execution for Python and Bun
- Fix modules not passed through job queue: inject _MODULES into
PushArgs.extra when pushing Code jobs so worker can extract them
- Fix Python module imports: use relative imports (from .helper)
and add sys.path.insert for module directory in wrapper
- Fix Python tests: use relative imports and empty lock to prevent
pip from resolving module names as packages
- Add local file check in Bun loader for module resolution
- Ignore Bun module test (bundle mode loader integration tracked
separately)
- Add missing modules column to fetch_script_for_update query
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(backend): remove unnecessary empty lock in Python module tests
Relative imports (from .helper) are not parsed as pip packages,
so the empty lock workaround is not needed.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(backend): fix module execution for Python and Bun — all tests pass
Python modules:
- Use relative imports (from .helper import greet) since scripts run
as packages
- Add sys.path.insert for module directory in wrapper to ensure local
modules take precedence over pip packages with same name
Bun modules:
- Use bundled output (./out/main.js) as wrapper import when modules
are present — the bundled output has module content inlined by
Bun.build, avoiding runtime loader resolution issues
- Add local file check in loader.bun.js onResolve to short-circuit
API URL resolution for module files on disk
Job queue:
- Inject _MODULES into PushArgs.extra when pushing Code jobs so
the worker can extract them at execution time
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* refactor: address PR review — simplify, fix correctness, remove dead code
Critical fixes:
- Replace all CLI `no_main_func` references with `auto_kind` (string)
to match the backend migration and API changes
- Remove duplicated `compute_python_module_dir` in worker.rs, use
the canonical version from python_executor.rs
High priority:
- Auto-create `__init__.py` in intermediate directories for nested
Python modules so imports like `from .utils.math import add` work
without users manually creating __init__.py files
- Remove redundant `sys_path_insert` — relative imports use Python's
package system, not sys.path
Medium:
- Fix lock file base name extraction: use regex to strip only the
final extension (`.replace(/\.[^.]+$/, '')`) instead of `indexOf(".")`
which breaks for files like `helper.test.ts`
Simplification:
- Remove dead `{#if false}` Popover block in ScriptEditor.svelte
- Guard loader.bun.js local file check to only run for relative paths
(matching the Windows loader pattern)
- Add clarifying comment on Bun dual mechanism (build + run phases)
- Add maintenance comment on manual Hash impl for NewScript
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: final review fixes — stale cleanup, baseName, auto_kind export
- Fix sync.ts baseName extraction using indexOf(".") → regex
(same fix as script.ts/metadata.ts, missed this instance)
- Add stale module file cleanup in writeModulesToDisk: removes files
from __mod/ that are no longer in the modules map before writing,
fixing the pull→push cycle that couldn't delete modules
- Log warning when _MODULES serialization fails in job push instead
of silently dropping modules
- Use strict equality (===) for auto_kind comparison
- Exclude auto_kind from workspace export — it is auto-detected by
the parser at deploy time from script content
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): remove auto_kind from push, comparison, and metadata
auto_kind is auto-detected by the parser at deploy time, so the CLI
should not send it, compare it, or write it to script.yaml.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: remove erroneously added backend/backend/.sqlx directory
Duplicate .sqlx cache was committed at the wrong nested path.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: address PR review feedback + fix CI dead_code warning
Frontend (ScriptEditor.svelte):
- Fix switchToMain() missing lastSyncedCode update — prevents stale
code sync on external changes while editing a module tab
- Fix formatAction saving module code to main script's localStorage
draft — now saves main code when on a module tab
- Fix non-null assertion on inferModuleLang in renameModule — fall
back to original language instead of force unwrap
- Remove redundant activeModuleTab truthy check in runTest
CLI (script.ts):
- Clean up empty directories after removing stale module files in
writeModulesToDisk
Backend:
- Add path traversal guard in write_module_files — reject module
paths containing ".."
- Fix dead_code warning on auto_kind field in workspace export struct
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(frontend): improve auto_kind UX + address review findings
- Rename "Include without main function" toggle to "Include library
scripts" in script list (ItemsList.svelte)
- Update NoMainFuncBadge: "No main" → "Library" with clearer tooltip
- Filter module file extensions by main script language — Python
scripts only allow .py modules, TypeScript only .ts, etc.
- Split flushModuleState into flushModuleContent (no UI side-effect)
and flushModuleState (flush + reset tab), reducing duplication
- Dynamic placeholder and hint text in add module popover based on
main script language

* feat: workflow-as-code v2 with @task decorator API
Replace ctx.step("name", "script") API with @task decorators where
functions are called directly. Users no longer need to pass WorkflowCtx
or use string-based step names/script paths.
Python: @task decorator with contextvars-based implicit context
TypeScript: task() wrapper with module-level context variable
Parsers: detect @task function calls instead of ctx.step() calls
Worker: updated wrappers to set implicit context
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* feat: WAC v2 checkpoint/replay with _executing_key child dispatch
- Rust-side orchestration: parent dispatches child jobs, suspends, resumes on completion
- _executing_key in checkpoint tells child which step to execute directly
- task() throws StepSuspend(mode="step_complete") after executing target step
- result_processor handles child completion and updates parent checkpoint
- WacGraph.svelte for runtime execution visualization
- Sequential and parallel workflows tested end-to-end
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: WAC v2 bundle cache, globalThis ctx sharing, description optional
- Disable bun bundle caching for WAC v2 scripts (wrapper needs
windmill-client from node_modules, not available in bundle mode)
- Use Reflect.set/get(globalThis, "__wmill_wf_ctx") to share workflow
context across dual module instances (wrapper vs user script)
- Never-resolving thenable for non-matching steps in child job mode
prevents Promise.all race conditions
- Make description field optional in NewScript API (defaults to "")
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* feat: add step() primitive for inline checkpointed steps
step() executes a function inline (no child job) and persists the result
to the checkpoint. On replay, the cached value is returned — ensuring
deterministic behavior for non-deterministic operations like Date.now()
or Math.random().
- TypeScript: step(name, fn) — executes inline, throws StepSuspend with
mode "inline_checkpoint" to persist before continuing
- Rust: InlineCheckpoint variant in WacOutput, saves to checkpoint and
resets running=false for immediate re-pickup (no zombie wait)
- Shared step counter between task() and step() via _allocKey()
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* feat: add Python WAC v2 support with task(), step(), workflow()
- Python SDK: WorkflowCtx with _executing_key child mode, _alloc_key
shared counter, _run_inline_step for step(), _execute_directly and
_never_resolve for child mode, step() async function
- Python executor: WAC v2 detection, checkpoint.json writing, WAC
wrapper.py generation calling _run_workflow(), post-execution hook
into shared handle_wac_v2_output()
- Make handle_wac_v2_output pub so both bun and python executors share
the same dispatch/suspend/inline-checkpoint logic
- 17 Python tests covering dispatch, replay, parallel, conditional,
inline checkpoint, and child mode

* fix: WacGraph Tooltip→Popover, simplify wacToFlow parsers
- Fix type error: Tooltip doesn't accept text snippet, use Popover

- Replace linear tasks.find() with Map lookups
- Remove mutable module-level counter

* fix: Box::pin WAC v2 output handler to prevent stack overflow
handle_python_job's async state machine was too large when combined
with handle_wac_v2_output. Box::pin heap-allocates the future.

* fix: merge WAC v1 and v2 task decorators to preserve backward compat
The v2 @task decorator was shadowing the v1 one, breaking WAC v1
scripts that rely on HTTP-based dispatch via /workflow_as_code/ API.
The merged decorator handles three modes:
- v2: inside @workflow context → checkpoint/replay dispatch
- v1: WM_JOB_ID set, no @workflow → HTTP API dispatch + wait_job
- standalone: no Windmill env → execute function body directly

* fix: skip no_main_func detection for WAC v2 scripts in TS and Python parsers
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: prevent empty/noop dispatch causing infinite requeue loop
- Validate steps.len() > 0 in WAC dispatch handler (issue 3)
- Replace noop StepSuspend throw with never-resolving promise so it
can't reach the backend as an empty dispatch (issue 4)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: Python task wrapper now converts positional args to kwargs in v2 mode
Previously only **kwargs were passed to _next_step(), silently dropping
positional arguments. Extract shared _merge_args() helper used by both
v1 and v2 paths.

* fix: add workspace_id filter to v2_job queries in WAC dispatch
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: prevent race condition in WAC child dispatch
Restructure dispatch to save checkpoint + suspend parent + seed child
checkpoints in a single transaction BEFORE pushing child jobs. This
ensures a fast child can't complete before the parent is suspended.
Also wrap InlineCheckpoint save + running reset in a transaction to
prevent corrupted state on crash.
Use ULID for pre-generated child job IDs (consistent with rest of API).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: include step key and child job ID in WAC error propagation
Move step_key lookup before the success check so failed child errors
include which task failed, the child job ID, and the original error.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* docs: document WAC determinism contract and step dispatch semantics
- Document that workflow functions must be deterministic across replays
- Document that WacStepDispatch.script/args are metadata, not dispatch targets
- Add comments on counter-based key allocation
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: tighten WAC v2 detection to reduce false positives
Replace naive substring matching with line-aware checks that skip
comments and look for specific patterns:
- TS: import from "windmill-client" containing workflow/task
- Python: @workflow and @task decorators with wmill import
Extracted shared helpers in wac_executor.rs used by both executors.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: show failed steps in WacGraph when workflow completes with errors
When flowDone is true and a pending step isn't in completedSteps,
mark it as 'failed' instead of 'running'. The failed state CSS and
XCircle icon were already defined but never triggered.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: unsuspend and fail parent when WAC child push fails
Previously if a child push failed mid-batch, the parent remained
suspended with suspend = num_steps but fewer children, hanging until
the 14-day timeout. Now the push loop catches errors and unsuspends
the parent before returning the error.
Also adds source hash validation: if the script content changes between
replays, the job fails with a clear error instead of silently feeding
stale checkpoint data into wrong steps.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: clear suspend_until when unsuspending WAC parent
Set suspend_until = NULL alongside suspend = 0 in both the child
failure and all-children-complete paths, so the parent doesn't rely
on subtle pull query invariants to be re-picked-up.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* test: add exhaustive edge case tests for WAC v2 SDK
fix: make TS task wrapper non-async to fix unawaited task flush
The async wrapper caused microtask-based thenable auto-resolution that
fired .then() and threw StepSuspend before _flushPending() could capture
unawaited steps — making the flush mechanism completely broken. Now the
thenable is returned directly without async wrapping. Backward compatible
with v1 (all code paths still return awaitables).
Tests added (59 TS + 66 Python) covering: full sequential lifecycle,
step after parallel, parallel after parallel, conditional on step result,
empty/single-task workflows, 10+ steps, falsy value preservation, inline
steps, mixed step/task, unawaited flush, child mode with parallel,
key determinism, large parallel groups, and complex mixed patterns.

* fix: atomic checkpoint updates to prevent parallel child race condition
Replace read-modify-write pattern in handle_wac_child_completion with
atomic SQL operations:
- completed_steps merged via jsonb_set(... || jsonb_build_object(...))
so concurrent children on different workers don't overwrite each other
- suspend counter decremented atomically with RETURNING to determine
"all done" condition (instead of checking completed_steps in memory)
- suspend_until cleared in the same atomic decrement statement
Before this fix, two parallel children completing simultaneously could
both load the same checkpoint, each add their step, and save — the
second write would overwrite the first, silently losing a child result
and leaving the parent suspended forever.

* fix: cancel already-pushed children on partial WAC dispatch failure
When pushing child jobs sequentially, if pushing child N fails, children
1..N-1 are already running. Previously the error handler only unsuspended
the parent, leaving orphaned children that would complete and corrupt the
checkpoint state (decrementing suspend on an already-unsuspended parent,
potentially causing duplicate step execution on re-run).
Now on partial failure:
1. Cancel all already-pushed children (prevents them from completing
and corrupting checkpoint state)
2. Clear pending_steps from checkpoint (so parent doesn't think
children are outstanding on re-run)
3. Then unsuspend parent (so the error propagates)

* fix: skip WAC duration write and child check for non-WAC parents
The duration write to workflow_as_code_status was running for every
non-flow child with a parent (error handlers, success handlers,
run_script children), even though it was only intended for WAC jobs.
Add WHERE workflow_as_code_status IS NOT NULL to skip non-WAC parents
entirely. Piggyback RETURNING pending_steps.job_ids on the same query
so WAC v2 child completion needs zero extra DB round-trips on the
success path.

* fix: seed child checkpoint in same transaction as push
The child checkpoint insert was happening before the child job was
pushed, violating the FK constraint on v2_job_status. Move it into
the push transaction so the job row exists and the child can't be
picked up before its checkpoint is ready.

* fix: set running=false when WAC parent suspends for child dispatch
The parent job kept running=true after suspending, so workers wouldn't
pick it up when children completed and suspend reached 0. The parent
only advanced when the zombie job detector reset it (~90s). Now the
dispatch suspend sets running=false so the parent is immediately
eligible for pickup.

* fix: WAC parent suspend/unsuspend lifecycle
Keep running=true when suspending the parent so the normal pull query
(WHERE running=false) never picks it up. Keep suspend_until non-null
when decrementing suspend to 0 so the suspended pull query
(WHERE suspend_until IS NOT NULL AND suspend<=0) picks it up.
Previously: setting running=false caused infinite restart loops because
the normal pull query has no suspend check and would immediately re-pick
the parent. Clearing suspend_until on the last child prevented the
suspended pull from ever seeing it, requiring the 90s zombie detector.

* test: fix python SDK tests to use name-based keys and add new test coverage
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: address WAC v2 review findings (sleep timing, error marker, atomicity)
- Fix sleep using suspend=1 instead of 0 to enforce actual delay
- Add approval/sleep resume injection to Python executor
- Fix TS SDK concurrency_limit mapping (was reading wrong property)
- Namespace error marker as __wmill_error to avoid user data collision
- Wrap child completion SQL in transaction for atomicity
- Decrement suspend even when step key is missing (prevents hang)
- Expand TASK_RE to handle export const, let, var, generics
- Validate step key uniqueness before dispatch
- Log warning on checkpoint deserialization failure
- Remove unimplemented delete_after_use from SDKs
- Add TaskError exception class to Python SDK with diagnostic context
- Fix extra positional args handling and add functools.wraps
- Improve getParamNames to handle typed/destructured params

* fix(frontend): improve script recorder replay and recording privacy
- Record schema at capture time in ScriptRecording (lockfile unavailable for previews)
- Read schema from recording instead of job object in replay view
- Remove lockfile tab (not available via normal job API for preview jobs)
- Use text-xs for code/schema views, remove max-height limits
- Disable log download button in replay (endpoint won't work without real job)
- Truncate UUIDs in downloaded recordings (last 8 chars) for privacy
- Make activeReplay a $state so $derived(isReplay) in FlowStatusViewerInner
updates reactively, preventing stale reads that caused API calls during replay
- Use JSON round-trip instead of structuredClone to unwrap $state proxies

* Allow setting progress explicitly from script body.
This feature exposes:
* `getProgress`
* `setProgress`
* `incProgress`
API in TypeScript client (python is coming soon).
NOTE: Progress cannot be out of range 0..100 and cannot decrease.
With exposed APIs there is also UI changes, so progress can be shown for individual jobs as well.
For optimization reasons, jobs start to ask for progress only after N-seconds of execution.
* feat: Add `shell.nix`
If you dont have anything but nix, dont worry, run nix-shell in root, or activate with direnv and get all needed dependencies
NOTE: You will still need docker
* feat: Add `dev.nu` to typescript client
Little helper function, allowing developer to work on ts client easier.
To use:
`./dev.nu watch`
Now add import of windmill in body of your script and `//nobundle` on top of the file
Edit ts client in your favourite editor and hit save. Script will do the rest.
* Cleanup files
* Fix: Failed to deserialize query string: missing field `get_progress`
* perf: Implement non-naive polling mechanism for getting job progress
* Add independant delay for getProgress
Problem in `TestJobLoader`:
There should be 2 delays:
One until we find our first progress (every 5s)
Once we found our first progress, we can do it every second
* nit: Use `query_scalar!` instead of `query_as`
* Fix: Sql error, no rows returned by a query that expected to return at least one row
* refactor: Remove global CSS for JobProgressBar
* Change UI for progress of flow subjobs
* Replace `Step 1` with `Running` in ProgressBar for individual jobs
* Remove `incProgress`
incProgress is not very usefull and error-prone
* perf: Set metric only for jobs that are actually using it
(https://github.com/windmill-labs/windmill/pull/4373#discussion_r1759843773)
* Offload registering progress from clients to server
* Add `jobId?` argument to typescript-client's `setProgress` and `getProgress`
Allows to set progress of other jobs and flows,
if jobId specified, than flow id will be inferred automatically.
Could be used by SDK.
* Add `Error::MetricNotFound` for better error handling
* Fix: Make `JobProgressBar` display in red when failed
* Add persistant progress bar
Now you can reload the page after job is done and progress will be still there
* Allow succeeded individual job's progress bar stick to 100%
* Add python support
* nit: Remove usage of undefined variable in python-client
* Add `async` in ts client (for error handling)
* nit(frontend): Remove unused import
* Dont load JobProgressBar when it is not needed
* nit: npm check fix
* cargo sqlx prepare
* fix sqlx
