Vapor v4.7.0 Release Notes

Release Date: 2020-05-27 // almost 4 years ago

  • 🚀 ###### This patch was authored and released by @tanner0101.

    • Implements new state machine for handling streaming request bodies (#2357).

    This new state machine ensures that calls to req.body.drain will only ever happen after the previously returned future has completed. This makes it easier to correctly implement streaming file writes. Addresses https://forums.swift.org/t/how-to-use-nonblockingfileio-for-repeated-writes/36206.

    • 🛠 Request bodies are now automatically drained after sending a response (#2357, fixes #2356).

    This change ensures that streaming requests will be read completely even if a route ignores their body.

    ➕ Adds a streaming file upload example to the Development executable (#2357).

    👌 Improves BodyStreamResult's normal and debug descriptions (#2357).

    🛠 Fixed a reference cycle if Request was captured strongly within the body.drain closure (#2357).
