Keep the ocx start synopsis complete across the user-facing documentation.
The CLI supports a custom SOCKS endpoint, the default socks5://127.0.0.1:10808, and --socks5-off for clearing the saved proxy. The changed synopses expose only part of this contract.

Reject SOCKS4 values for --socks5.
Line 25 accepts socks4:// and socks4a:// because isSocksProxyUrl permits both schemes. This contradicts the SOCKS5-only option and help text. Use a SOCKS5-specific check in normalizeSocks5, while retaining generic scheme detection elsewhere only if legacy routing requires it. Add rejection coverage for SOCKS4 input.

Reviewed exact head 6ede9280ce9ae03366b9ff47c2ab84bf512d0b96. Persistent outbound SOCKS support is valuable, but this draft is not mergeable as-is:
- Retarget and rebuild on current
dev. This PR targetsmain, carries release ancestry, and is currently 86 commits behinddev;enforce-targetis correctly failing. - Redact proxy userinfo in both CLI and server startup logs. The routing value may retain credentials, but logs must never print the username or password.
- Provide an integration test proving the Bun outbound path actually honors a persisted
ALL_PROXY=socks5://...value for provider traffic. Environment assignment alone is not evidence that the runtime transports use SOCKS5. - Make
--socks5-offremove only a SOCKS proxy or document/rename the broader behavior; it currently clears an existing HTTP proxy too. Reject simultaneous--socks5and--socks5-offinstead of making argument order decide. - Reject
socks4://andsocks4a://for a SOCKS5-only option and add focused rejection tests. - Resolve the open documentation contract threads and run exact-head CI after the current-
devrecut.
Please keep the PR open while addressing these boundaries; the direction is useful, but the current target, credential logging, and unproven transport behavior are blocking.

@lidge-jun @Ingwannu maintainer action needed: the current PR head contains the completed SOCKS5 transport/security fixes, but the required maintainer-sponsored label is still missing. GitHub does not allow the PR author to apply this label. Please review the current head for the security-boundary changes and, if satisfied, add maintainer-sponsored; then the hygiene check can rerun. The PR remains draft until the review-readiness checklist is truthfully completed. |

Re-reviewed exact head 1eaaed1c7b47d47a22a673ae846e994e59cbbab9. The current-dev recut addresses the previous target, userinfo-redaction, SOCKS4, conflicting-flag, --socks5-off, transport-proof, and locale-doc blockers, but the new one-shot SOCKS transport has a resource-lifetime blocker. responseBody().finish() only removes listeners and disposes SocketReader; it never clears/destroys the socket. The bodyless path does the same. I reproduced this on the exact head with a raw SOCKS endpoint that returned Content-Length: 2 and kept the connection open: response.text() completed with ok, but the accepted socket was still open (destroyed === false) 25 ms later. Because this transport creates a fresh connection and advertises Connection: close rather than pooling it, a noncompliant or hostile upstream can retain one file descriptor per successful request until the 200 s inactivity timeout. Close the socket and clear its timeout when a fixed-length/chunked/EOF body reaches terminal completion and for bodyless responses, then add the keep-alive regression. Also make request-body backpressure wait on drain or error/close/abort: the current await new Promise(resolve => socket.once("drain", resolve)) can remain pending forever after the socket is destroyed, and the plain HTTP path has no error listener at that point. Keep this draft without maintainer-sponsored until both lifetime boundaries are covered and exact-head focused CI is green.

Update for the latest review: pushed commit 70a24c3 with response-socket lifetime cleanup, bodyless-response cleanup, drain/error/close/abort backpressure handling, and fixed-length/bodyless keep-alive regressions. Local SOCKS5 tests pass (9/9) and typecheck passes. GitHub hygiene, labeler, and target checks are green on this exact head. Please re-review this head for the requested lifetime boundaries; the PR remains draft pending maintainer review and sponsorship. |

Re-reviewed exact head 70a24c3c438149875bad8c6f3128c365bfa60ec8. The response-lifetime blocker is fixed: fixed-length and bodyless responses now clear the timeout, dispose the reader, and destroy the one-shot socket, and both new keep-alive regressions pass. The waitForDrain implementation also has the right event set and cleanup shape.
One blocker remains before I can add maintainer-sponsored: add a regression that actually enters request-body backpressure, observes socket.write(...) === false, and then proves an error, close, or caller abort rejects the pending send without waiting for a never-arriving drain. The current 32 focused tests pass, but none executes waitForDrain; the only abort test stops during the SOCKS handshake. This was the second concrete lifetime failure in my prior review, so implementation without an executable guard is not enough for a security-boundary sponsorship.
Please keep the test deterministic and bounded, and verify listener cleanup after settlement. Once that is present, the readiness checklist is truthfully completed, and exact-head focused/hosted CI is green, I can sponsor this draft.
|
Follow-up pushed in commit 72667fd: added deterministic request-body backpressure coverage. The test forces the real HTTP body write to return alse, injects a socket error before drain, asserts bounded rejection, and verifies drain/error/close listener cleanup. Local SOCKS5 suite is 10/10 and typecheck passes. Please re-review this exact head; hosted checks are running. |
|
Hosted validation completed successfully on 72667fd: hygiene, labeler, resolve-pr, and enforce-target are all green. The local SOCKS5 suite is 10/10 and typecheck is green. The only remaining action is maintainer re-review of this exact head and sponsorship; the PR is intentionally still draft. |
Clash mixed-port HTTP_PROXY cannot CONNECT a SOCKS listener. ocx start --socks5 writes socks5:// into config.proxy and ALL_PROXY so routing survives ocx update.
Route configured provider and ordinary HTTP(S) fetches through a dependency-free SOCKS5 tunnel with authentication, streaming, aborts, and NO_PROXY support. Persist safe CLI controls, disable incompatible WebSocket routing, and synchronize tests and documentation.
Prevent one-shot SOCKS5 requests from leaking connections or hanging forever when request backpressure ends in an error, close, or abort.
Exercise the request-body backpressure path and verify socket failures settle the request without leaving listeners behind.

Current dev added an allowlist for fetch-helpers runtime imports. The SOCKS5 transport already loads configuredOutboundFetch from lib/proxy-env; include that specifier so the boundary matches the rebased transport. Co-authored-by: Warexpor <warexpor@gmail.com>
