Ruben Fiszel d578e40101 feat: add selfApproval option to WAC + inline approval buttons (#8440)
* 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

* 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

* 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

* 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.

* 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.

* 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.

* 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

wmill

The core client for the Windmill platform.

Usage

Basic Usage

The wmill package has several methods at the top-level for the most frequent operations you will need.

The following are some common examples:

import time

import wmill


def main():
    # Get the value of a variable
    wmill.get_variable("u/user/variable_path")
    
    # Run a script synchronously and get the result
    wmill.run_script("f/pathto/script", args={"arg1": "value1"})
    
    # Get the value of a resource
    wmill.get_resource("u/user/resource_path")
    
    # Set the script's state
    wmill.set_state({"ts": time.time()})
    
    # Get the script's state
    wmill.get_state()

Advanced Usage

The wmill package also exposes the Windmill class, which is the core client for the Windmill platform.

import time

from wmill import Windmill

def main():
    client = Windmill(
        # token=...  <- this is optional. otherwise the client will look for the WM_TOKEN env var
    )

    # Get the current version of the client
    client.version

    # Get the current user
    client.user
    
    # Convenience get and post methods exist for https://app.windmill.dev/openapi.html#/
    # these are thin wrappers around the httpx library's get and post methods
    # list worker groups
    client.get("/configs/list_worker_groups")
    # create a group
    client.post(
        f"/w/{client.workspace}/groups/create",
        json={
            "name": "my-group",
            "summary": "my group summary",
        }
    )
    
    # Get and set the state of the script
    now = time.time()
    client.state = {"ts": now}
    assert client.state == {"ts": now}
    
    # Run a job asynchronously
    job_id = client.run_script_async(path="path/to/script")
    # Get its status
    client.get_job_status(job_id)
    # Get its result
    client.get_result(job_id)
