* feat(websocket-trigger): honor HTTPS_PROXY/HTTP_PROXY/NO_PROXY (WIN-1988)
`tokio_tungstenite::connect_async` opens a raw TCP socket and ignores
the standard outbound-proxy env vars, so deployments behind a forward
HTTP proxy can't reach the WebSocket endpoint and Test Connection
times out after 30s.
Add a small `proxy` module that resolves the right proxy URL for the
target host (HTTPS_PROXY for wss://, HTTP_PROXY for ws://, NO_PROXY
exclusions, ALL_PROXY fallback, lowercase variants), opens an HTTP
CONNECT tunnel when one applies, and hands the resulting TcpStream to
`client_async_tls_with_config` for the TLS + WS handshake. Direct
connect remains the default when no proxy env is set.
Unit tests cover NO_PROXY matching, proxy URL parsing (including IPv6
literals and basic-auth userinfo), and the CONNECT handshake itself
against an in-process fake proxy (success, basic-auth header, 407
rejection).
Fixes WIN-1988
* refactor(websocket-trigger): reduce blast radius and reuse existing logic
Follow-up to the proxy support change. Three things:
1. Skip the new code path entirely when no proxy is configured.
`connect_async_with_proxy` now checks the env-var snapshots up front
and delegates straight to `tokio_tungstenite::connect_async` if
neither `HTTP_PROXY` nor `HTTPS_PROXY` is set. Same fall-through
applies when proxy env is set but `NO_PROXY` excludes the host or
the proxy URL doesn't parse. Non-proxied deployments now exercise
exactly the previous code path.
2. Move the `NO_PROXY` / `HTTP_PROXY` / `HTTPS_PROXY` env-var snapshots
from `windmill-worker::worker` into `windmill-common`. The worker's
`PROXY_ENVS` static now reads from there, and the websocket trigger
reads from the same source — one place reads the env, one source
of truth for both call sites.
3. Replace the hand-rolled proxy-URL parser with `url::Url::parse`
(already a workspace dep, used across the codebase). Half the LoC
and handles edge cases (userinfo percent-encoding, IPv6 literals,
path/query stripping) via the well-tested crate instead of by hand.
All 13 proxy unit tests still pass. `cargo check` is clean.
* fix(websocket-trigger): unbreak EE build + trim proxy tests
- Re-export `NO_PROXY` / `HTTP_PROXY` / `HTTPS_PROXY` from
`windmill-worker::worker` (via `pub use windmill_common::...`) so the
EE `otel_tracing_proxy_ee` module's `use crate::{HTTPS_PROXY, ...}`
resolves like it did before. Fixes the `check_ee_full` / `cargo_test`
CI failures from the previous commit.
- Trim the proxy tests to one un-ignored canary
(`http_connect_tunnel_sends_well_formed_request_and_unwraps_stream`)
that exercises the actual on-wire CONNECT handshake plus byte-perfect
tunnel passthrough. The NO_PROXY-matching, URL-parsing, and edge-case
tunnel tests are kept under `#[ignore]` for manual debugging
(`cargo test -- --ignored`) since they're either delegated to
`url::Url::parse` or trivial string matching — low ROI on every CI run.
