The diffs are committed. Users now can use SBPlatform SetLocateModuleCallback to set ‘locate module callback’ (renamed from ‘get module callback’).

def locate_module(
    module_spec: lldb.SBModuleSpec,
    module_file_spec: lldb.SBFileSpec,
    symbol_file_spec: lldb.SBFileSpec,
) -> lldb.SBError:
     name = module_spec.GetFileSpec().GetFilename()
     uuid = bytes(
        ctypes.pointer(
            (ctypes.c_char * module_spec.GetUUIDLength()).from_address(
                int(module_spec.GetUUIDBytes())
            )
        ).contents
    ).hex()

    # Implement module locating logic with module_spec arg.
    # e.g. find module file and symbol file from cache with UUID.

    if module_dir and module_file:
        module_file_spec.SetDirectory(module_dir)
        module_file_spec.SetFilename(module_file)

    if symbol_dir and symbol_file:
        symbol_file_spec.SetDirectory(symbol_dir)
        symbol_file_spec.SetFilename(symbol_file)

    return lldb.SBError()
