📝 Walkthrough

Walkthrough

The CLI adds a hidden ingress-server daemon with HTTP, HTTPS, and Unix-socket listeners. It adds /sync and /validate routes, TLS and mTLS validation, shared TLS-keyed clients, structured logging, readiness checks, graceful shutdown, and synchronous backend construction.

Changes

Ingress server integration

Layer / File(s) Summary
Backend client and pipeline refactor
rust/Cargo.toml, rust/crates/adc-backend-*/**, rust/crates/adc-backend-core/src/{client.rs,tls.rs}, rust/crates/adc-cli/{Cargo.toml,src/main.rs,src/pipeline.rs}
Workspace dependencies are centralized. Backend construction uses BackendSpec. Shared clients apply request timeouts. TLS configuration can build clients.
Ingress request and backend setup
rust/crates/adc-cli/src/{cli.rs,server/agent_pool.rs,server/backend.rs,server/schema.rs}
The hidden command, request schemas, PEM validation, TLS-material client pooling, and server-side backend conversion are added.
Server runtime and request logging
rust/crates/adc-cli/src/server/{mod.rs,logging.rs}
The server supports HTTP, HTTPS, Unix sockets, readiness responses, mTLS, graceful shutdown, body limits, structured errors, request IDs, and redacted JSON logging.
Sync and validate request flows
rust/crates/adc-cli/src/server/{sync.rs,validate.rs}
The handlers validate input, apply filters and linting, build backends, execute synchronization or validation, and return structured JSON responses.
TLS and process integration coverage
rust/crates/adc-cli/tests/assets/tls/*, rust/crates/adc-cli/tests/ingress_server_sigint.rs
TLS assets, certificate-generation support, and subprocess tests cover mTLS behavior and SIGINT shutdown.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to 5930a

This PR adds an ingress server, but the current implementation can expose its status endpoint publicly, write sensitive credentials or TLS material to debug logs, and delete regular files at configured socket paths; its pool tests also fail before validating their intended behavior. These concrete security, data-loss, and test-validity risks should be fixed before merging.

Return the result instead of calling std::process::exit in the arm.

The other arms return a Result that the block below maps to an exit code. This arm exits directly. That duplicates the error printing at Lines 60-63 and skips any flush that a guard-based tracing writer performs at scope end. Returning the result keeps one exit path.

The assertion on error text is brittle.

ping_fails_certificate_verification_without_a_ca_cert matches on lowercased substrings of the rustls error text. A rustls or reqwest upgrade can reword that message and break the test without a behavior change. Assert on the BackendError variant instead, and keep the text check as a secondary assertion.

Do not replace a failed body read with an empty body.

to_bytes fails when the client disconnects or the body exceeds the limit. The current code substitutes an empty body and forwards the request. The handler then reports a JSON parse error with HTTP 400, which hides the real cause. Return the transport error instead.

♻️ Proposed change to surface the read failure

Clone the events only for the standalone branch.

Consider the status code when the sync partially or fully fails.

run returns Ok even when every event fails on every server, and the handler answers 202 Accepted. Clients that branch on the HTTP status alone treat a total failure as accepted. Confirm this matches the existing API contract, or return a non-2xx status when status is all_failed.

Set kill_on_drop(true) on both spawned children.

free_port has a bind race.

The listener closes when the function returns, so the port is free before the child binds it. Another process, or the second test running in parallel, can take it. The child then fails to bind and the test fails with a confusing "server never became ready" message.

Bind port 0 in the server and read the chosen port, or retry the spawn on a bind failure. If neither is practical, assert on the child's stderr when readiness times out, so the failure names the real cause.

Committed private keys trigger secret scanners.

These keys are test fixtures produced by generate-mtls.sh, so there is no production exposure. Secret-scanning tools still flag them, as the static analysis hint shows. Two options reduce the noise:

  • Generate the chain in a test setup step or build.rs instead of committing the keys.
  • Keep the files and add an allowlist entry plus a short README in tests/assets/tls/ that states they are throwaway fixtures.

133-141: 🔒 Security & Privacy | 🔵 Trivial | 💤 Low value

Close the permission window on the Unix socket.

bind creates the socket with the process umask, and set_permissions applies 0o660 only afterwards. Another local user can connect during that window if the umask is permissive. Create the socket inside a directory with restrictive permissions, or set the umask around the bind call.

Also consider removing the socket file during shutdown, so the next start does not depend on the stale-file cleanup path.

- Around line 69-71: Update parse_listen_url to validate the parsed URL scheme
and accept only http, https, or unix; return a descriptive Err for all other
schemes so clap rejects invalid arguments during parsing.

In `@rust/crates/adc-cli/src/pipeline.rs`:
- Around line 120-138: Ensure the shared-client path honors request timeouts: in
http_client, apply the timeout argument to Some(client), or reject
configurations where it cannot be honored. In
rust/crates/adc-cli/src/server/backend.rs lines 20-36, replace timeout: None
with a concrete default and expose that setting through the Opts schema. In
rust/crates/adc-backend-core/src/client.rs lines 65-96, update the
with_shared_client documentation to state that the caller-owned pooled client
supplies the timeout.

Apply the same fix in `@rust/crates/adc-backend-core/src/client.rs` around lines
65 - 96.
- Around line 79-118: Update init_backend to distinguish an empty or absent
spec.kind, which should retain the default APISIX behavior, from non-empty
unrecognized kinds, which must return a CliError instead of falling through to
APISIX. Preserve the existing explicit "api7ee" and "apisix-standalone" branches
and APISIX construction for the valid/default case.

In `@rust/crates/adc-cli/src/server/agent_pool.rs`:
- Around line 75-76: Update the test helper material to provide valid
PEM-encoded CA certificates, using distinct fixtures for each cache key so
TlsConfig::build_client succeeds while testing client reuse and LRU eviction.
Keep the existing TlsMaterial construction behavior unchanged apart from
replacing the invalid certificate literals.

In `@rust/crates/adc-cli/src/server/logging.rs`:
- Around line 43-50: Update redact_request_body to mask the backend token field
in addition to /task/opts/tlsClientKey, using the request schema’s token
location and preserving the existing redaction behavior for all other fields.

In `@rust/crates/adc-cli/src/server/mod.rs`:
- Around line 60-67: The status listener currently binds to
Ipv4Addr::UNSPECIFIED instead of honoring the configured host. Update the
status-address construction in the server startup flow to reuse the host from
args.listen while retaining the configured status port, or extend the status
option to accept a complete address; preserve the existing bind error handling.
- Around line 79-97: Introduce shared readiness state initialized as false, pass
it to the status router, and have healthz return service unavailable until the
state is true. Update serve_adc and its listener-binding paths to signal
readiness immediately after the ADC listener successfully binds, while
preserving the existing ready response afterward.
- Around line 164-176: Update the HTTPS shutdown task around axum_server::Handle
and wait_for_shutdown so graceful_shutdown uses a finite deadline, matching the
intended bounded shutdown behavior and preventing idle keep-alive connections
from blocking process exit.

In `@rust/crates/adc-cli/src/server/schema.rs`:
- Around line 187-189: Update validate_tls_material to fully parse and validate
every TLS field before backend construction, rather than relying on is_pem_like,
so incomplete PEM values produce validation errors instead of deferred
client-construction failures. Replace the placeholder PEM values in the affected
TLS fixture cases with valid certificates/keys, and associate a lone
tlsClientKey validation error with the missing tlsClientCert field.

Apply the same fix in `@rust/crates/adc-cli/src/server/schema.rs` around lines 164
- 169.

In `@rust/crates/adc-cli/tests/assets/tls/ca.csr`:
- Around line 1-15: Regenerate the ca.csr fixture from the existing ca.key so
its public key matches ca.cer and ca.key; if the fixture-generation flow does
not use the CSR, remove ca.csr instead.

167-219: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Fully validate TLS objects before backend construction.

rustls_pemfile::certs and rustls_pemfile::private_key extract PEM items. They do not prove that a PEM-wrapped value is usable TLS certificate or key material. A request can pass this validation and fail later in backend construction, where the handler returns HTTP 500 instead of HTTP 400.

Add validation for PEM-wrapped invalid DER data. Validate the client certificate and key with the same TLS parser used by client construction.

#!/bin/bash
set -euo pipefail

# Inspect the validation and error-mapping path without executing repository code.
rg -n -C 8 \
  'validate_tls_material|is_valid_pem_certificate|is_valid_pem_private_key|internal_error|build_backend' \
  rust/crates/adc-cli/src/server

# Confirm the locked dependency declarations before selecting a complete parser.
fd -a 'Cargo.toml|Cargo.lock' rust . | while IFS= read -r file; do
  rg -n -C 3 'rustls-pemfile|reqwest' "$file" || true
done

- Around line 26-28: Update the body-read error handling in the request handler
to detect when the error source is http_body_util::LengthLimitError and return
StatusCode::PAYLOAD_TOO_LARGE; preserve StatusCode::BAD_REQUEST for all other
errors. Add http-body-util as a direct dependency if required to perform the
downcast.

In `@rust/crates/adc-cli/tests/ingress_server_sigint.rs`:
- Around line 80-83: Update the startup-read flow in the ingress SIGINT test to
match the result of timeout around lines.next_line(). Fail with a clear startup
diagnostic on timeout, read error, or missing output, and only call libc::kill
after successfully receiving the expected readiness line so the child is proven
alive and ready.

44-48: 🔒 Security & Privacy | 🟠 Major | ⚡ Quick win

Do not log unparseable request bodies.

redacted_body_text returns the complete raw body when JSON parsing fails. A malformed request can still contain task.opts.token or tlsClientKey data. Debug logs then persist that data without redaction.

Log a fixed non-JSON marker and the body length instead.

Proposed fix
-        Err(_) => String::from_utf8_lossy(bytes).into_owned(),
+        Err(_) => format!("<non-JSON request body: {} bytes>", bytes.len()),

Reject non-socket paths before cleanup.

serve_unix removes every existing path, including regular files. A mistaken unix:// path can delete a file during server startup.

Inspect the existing entry with symlink_metadata. Remove it only when it is a Unix socket. Return an error for every other file type. Update the test at Line 510 to create a stale socket instead of a regular file.
