Version 0.13.0

0.13.0 (April 21st, 2021)

The 0.13 release updates the core API in order to match the HTTPX Transport API,
introduced in HTTPX 0.18 onwards.

An example of making requests with the new interface is:

with httpcore.SyncConnectionPool() as http:
    status_code, headers, stream, extensions = http.handle_request(
        method=b'GET',
        url=(b'https', b'example.org', 443, b'/'),
        headers=[(b'host', b'example.org'), (b'user-agent', b'httpcore')]
        stream=httpcore.ByteStream(b''),
        extensions={}
    )
    body = stream.read()
    print(status_code, body)

Changed

• The .request() method is now handle_request(). (Pull #296)
• The .arequest() method is now .handle_async_request(). (Pull #296)
• The headers argument is no longer optional. (Pull #296)
• The stream argument is no longer optional. (Pull #296)
• The ext argument is now named extensions, and is no longer optional. (Pull #296)
• The "reason" extension keyword is now named "reason_phrase". (Pull #296)
• The "reason_phrase" and "http_version" extensions now use byte strings for their values. (Pull #296)
• The httpcore.PlainByteStream() class becomes httpcore.ByteStream(). (Pull #296)

Added

• Streams now support a .read() interface. (Pull #296)

Fixed

• Task cancelation no longer leaks connections from the connection pool. (Pull #305)
