Problem

OpenTubeX#720 moves saved channel playback speeds into the existing encrypted Settings sync flow. Once updated clients are deployed, the dedicated playback-speed API and encrypted collection become redundant, but removing them immediately would break older clients.

Solution

  • Mark the dedicated playback-speed endpoints as deprecated in the generated OpenAPI documentation.
  • Return the RFC 9745 Deprecation response header from those endpoints.
  • Document that both the plaintext API and encrypted playbackSpeeds collection remain supported during the migration period.
  • Retain all storage, quota, migration, and cleanup behavior until older supported clients have been phased out.

No sunset or removal date is introduced by this PR.

Validation

  • Rust formatting check
  • Clippy across all targets with warnings denied
  • All 28 offline server tests, including database quotas, encrypted collections, authentication, migrations, and rate limiting

The four live YouTube metadata validation tests were also attempted, but the upstream response currently contains a DTD that the parser rejects; that failure is unrelated to these changes.

Review Change Stack

Warning

Review limit reached

@D3SOX, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 103 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The change deprecates channel playback-speed endpoints, adds a deprecation response header, preserves existing GET and PUT payloads, completes DELETE responses explicitly, and documents encrypted synchronization and legacy migration compatibility.

Changes

Playback synchronization deprecation

Layer / File(s) Summary
Playback endpoint deprecation behavior
src/handlers/channel_playback_speeds.rs
The playback-speed handlers are marked deprecated. GET and PUT responses retain their JSON payloads and add the deprecation header. DELETE explicitly completes an empty response with the header.
Encrypted sync and README documentation
src/handlers/encrypted_sync.rs, README.md
The documentation defines the synchronization scope, encrypted settings replacement, legacy collection support, migration constraints, deprecation headers, and removal status.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 7d949

The deprecated playback-speed endpoints may omit the advertised Deprecation header on some error responses, so clients will not receive a consistent migration signal; the PR is otherwise mergeable with explicit owner awareness or follow-up.

Greptile Summary

The PR deprecates the dedicated channel playback-speed API while preserving compatibility for older clients.

  • Adds RFC 9745 Deprecation headers to successful and error responses from the plaintext endpoints.
  • Marks the endpoint handlers deprecated for generated API documentation.
  • Documents the migration to encrypted settings while retaining the legacy encrypted collection, quotas, migration, and cleanup behavior.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains; the outer deprecation middleware now covers authentication and handler errors while preserving their original status and response body.

Important Files Changed

Filename Overview
src/handlers/channel_playback_speeds.rs Adds endpoint deprecation annotations and an outer middleware that applies the deprecation header to successful, handler-error, and authentication-error responses while preserving original response semantics.
src/handlers/encrypted_sync.rs Documents continued compatibility support for the deprecated playbackSpeeds encrypted collection without changing its limits or behavior.
README.md Documents the playback-speed migration and explicitly states that legacy forms remain functional without a scheduled removal date.

Narrow the deprecated lint allowance.

If only these route registrations need the suppression, move #[allow(deprecated)] to get_service or the smallest route-registration scope that compiles. The crate-level attribute suppresses unrelated deprecated-use diagnostics across the crate. Rust supports lint levels at crate and narrower item scopes. (doc.rust-lang.org)
