Davide Modolo 56e21bce83 fix(flows): stop re-evaluating skip_if once a loop is in progress (#11008)
* fix(flows): stop re-evaluating skip_if once a loop is in progress

skip_if is a one-time entry gate, but the flow stays at the same step
for a loop's whole lifetime, so it gets re-evaluated on every
iteration. previous_id stays pinned to the module preceding the loop,
but once the loop is InProgress the last completed job is an inner
iteration, and the results proxy in windmill-jseval aliases
results.<previous_id> to that job's result. skip_if then reads the
wrong value and can flip the loop's module to skipped after one
iteration.

Skip the check once status_module is already InProgress.

* fix(flows): match skip_if gate to sibling entry-state allowlists

Rewrite the skip_if gate as a positive allowlist (WaitingForPriorSteps
| WaitingForEvents | WaitingForExecutor), matching the shape already
used by the BranchOne/BranchAll predicate gates, instead of a negative
filter on InProgress. Restart-at-iteration also enters as InProgress;
document it as a separate case rather than folding it into the
aliasing reason, which does not apply there.

Add a regression test pinning skip_if to run once at while-loop entry.

Windmill Backend

This folder holds all backend components, the src/ folder only contains files used to build the "root" binary.

Components

name description
windmill-api The API server, exposing functionality to other components and the frontend
windmill-audit Contains audit functionality, allowing different components to record important actions
windmill-common Common code shared by all crates
windmill-queue Contains job & flow queuing functionality, commonly written to by the API server and read from by workers
windmill-worker The worker. Used to process and execute flows & jobs.
parsers Contains code to parse signatures in different langauges.
