Included review availability: Your plan provides up to 8 included reviews per hour; 6 remain after this review. 📝 WalkthroughWalkthroughThe API disables HTTP and proxy timeouts for file transfers. The Rust REST client applies a 24-hour timeout to file requests and keeps a 300-second timeout for control requests. Tests cover both behaviors and provide dedicated REST test execution. ChangesFile transfer timeout handling
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to This change extends long-running behavior beyond file transfers because the shared server no longer enforces request deadlines for unrelated API routes. That can allow stalled requests to consume resources longer than intended, so the PR is mergeable with explicit owner awareness or follow-up. Sequence Diagram(s)sequenceDiagram

Pull request overview
This PR extends BoxLite REST file copy operations (upload/download streaming) to tolerate slow networks by allowing file requests to run up to the 24-hour box lifetime, while keeping existing 300-second limits for non-file control requests and connection establishment. It also updates the API server and proxy layer to avoid prematurely aborting long-running file streams.
Changes:
- Rust: override reqwest’s per-request total timeout to 24h for file requests only; add connect timeout and add Tokio virtual-time coverage for the boundary.
- Node/Nest: disable Node’s server-level request body timeout and disable proxy timeout for the
/filesproxy route only. - Test harness: add focused Jest “contract” tests for the Node/server and proxy timeout settings; ensure Rust unit tests run the new REST client tests.

- This test pauses Tokio time but never advances it, so the request timeout will never elapse and
server.awaitwill also hang because the server task is sleeping for 301s of virtual time.
response_started_rx.await.unwrap();
tokio::time::pause();
start_delay_tx.send(()).unwrap();

Give file transfers a 24-hour request deadline while retaining the existing 300-second timeout for control requests and connections. Disable the cloud proxy and Node request-body deadlines that would otherwise terminate slow copies.

- These tests pause Tokio time and then use
tokio::time::sleep(..)to advance past the 300s boundary. That relies on Tokio's implicit auto-advance behavior and is easier to break/hang if runtime scheduling semantics change. Prefer explicitly advancing virtual time viatokio::time::advance(..)when time is paused so the intent is deterministic.
tokio::time::pause();
tokio::time::sleep(Duration::from_secs(301)).await;
tokio::time::resume();
src/boxlite/src/rest/client.rs:763
- Same as above: when time is paused, using
tokio::time::advance(..)is a deterministic way to move virtual time forward without depending on Tokio's auto-advance heuristics.
tokio::time::pause();
tokio::time::sleep(Duration::from_secs(301)).await;
tokio::time::resume();
src/boxlite/src/rest/client.rs:710
- The PR description's "How to verify" references
FILTER=file_request_uses_24_hour_timeout_and_outlives_default_timeout, but the actual test name isfile_request_outlives_default_timeout, so the suggested command won't select the intended test. Either update the PR description or rename the test to match the documented filter.
async fn file_request_outlives_default_timeout() {
Summary
Support BoxLite file uploads and downloads over slow networks for longtime(24h, a box should not longer then it in fact). Control requests and connection establishment keep their existing 300-second limits.
