The sioscgi module has been split into separate sioscgi.request and
sioscgi.response modules with separate types which can be used
independently.
Extra data after the request body is now ignored rather than raising an error.
Ruff linting and formatting was applied. Substantial internal refactoring was
performed. A more detailed exception hierarchy was introduced, with
LocalProtocolError and RemoteProtocolError becoming base classes.
CI configuration was updated. Very minor code cleanup was performed. This version requires Python 3.9 or higher due to updating to newer type hints.
CI configuration, lint configuration, and build system configuration were updated. Very minor code cleanup was performed.
The environment member of the RequestHeaders event now maps from
str to bytes rather than from str to str. This is because HTTP
header values do not have any standards-defined character encoding; therefore,
it must be left up to each application to decode each header as it sees
fit, if it intends to use the header value as textual data.
A py.typed file is now installed, allowing Mypy to type check consumers of
sioscgi.
The transmit and receive state machines have been split to allow interleaving
of request and response bodies. While such interleaving is not strictly
permitted by the SCGI specification, it is permitted by the CGI specification
and is supported by some SCGI clients. The state property in
SCGIConnection and the State enumeration no longer exist, having been
replaced with the rx_state and tx_state properties and the RXState
and TXState enumerations. Applications referring to these must be updated
to refer to the state machine about which they care; applications not referring
to these will continue to work without modification.
