[issue32395] asyncio.StreamReader.readuntil is not general enough

[Andrew Svetlov]

Andrew Svetlov <andrew.svetlov at gmail.com> added the comment:

Support multiple separators looks easy, I don't expect any performance impact.
Like we already have it for strings: s.startswith(('\n', '\r'))

Regexps are more expensive thing, callbacks are kind of evil.

Let's add a patch for multiple separators first, maybe it covers 99.9% use cases.
