Releases

v0.39.0

• Rename RequestRefusedError -> RefusedError.

v0.38.0

• write_request now raises Protocol::HTTP::RequestRefusedError if the request line or headers cannot be written, indicating the request was not processed and can be safely retried.

v0.37.1

• Defer body.close in write_chunked_body, write_fixed_length_body, and write_body_and_close until after the response is fully written and flushed. Previously, body.each called close in its ensure block before the terminal chunk (chunked encoding) or final flush was written, causing rack.response_finished callbacks to delay the client-visible response completion.

v0.37.0

• Protocol::HTTP1::BadRequest now includes Protocol::HTTP::BadRequest for better interoperability and handling of bad request errors across different HTTP protocol implementations.

v0.36.0

• Indicate trailers from chunked body for better validation by Protocol::HTTP::Headers.

v0.35.2

• Tidy up implementation of read_line? to handle line length errors and protocol violations more clearly.
