This updates and fixes the
streamlink.utils.argsmodule, in preparation for #5715 (which I will rebase and modify after this got merged - after the next release).The first commit keeps the same functionality as the current implementation, apart from different exceptions being raised. The tests have been fully rewritten, but the old tests also pass (ignoring the exception class changes).
The second and third commits fix some issues with the inputs of
filesize()andkeyvalue(). This will affect the--ringbuffer-sizeargument, as well as--http-header,--http-cookie,--http-query-param,--player-env,--twitch-api-headerand--twitch-access-token-param. This is mainly just whitespace character related but it fixes the missing regex anchors.The last commit fixes the incorrect
--ringbuffer-sizehelp text and removes an old and probably unnecessary note.
