hlrun.patch

A Python-based system for patching and hooking of bytecode, similar to DCCM.

class Patch​

Runtime stub version of the Patch class. Maintains API compatibility but provides no patching functionality in runtime mode.

name​

name = name

author​

author = author

sha256​

sha256 = sha256

interceptions: Dict[str | int, Callable[[Args], Args]]​

interceptions = {}

patches: Dict[str | int, Callable[[Bytecode, Function], None]]​

patches = {}

init​

def __init__(name: Optional[str] = None, author: Optional[str] = None, sha256: Optional[str] = None)

Initialize a new patch (runtime stub).

intercept​

def intercept(fn: str | int) -> Callable[[Callable[[Args], Args]], Callable[[Args], Args]]

Intercept (and modify arguments to) function calls at runtime.

patch​

def patch(fn: str | int) -> Callable[[Callable[[object, object], None]], Callable[[object, object], None]]

Patch bytecode statically before runtime.

apply​

def apply(code: object) -> None

Runtime stub for applying patches.

do_intercept​

def do_intercept(args: Args, identifier: str | int) -> Args

Runtime handler for interception. The only function in this runtime class that does something!

T​

T = TypeVar('T')
USE_CRASHLINK = False
