The error about "string is too long"

[Zhighway777]

My python version is 3.10.12
pytest version : 8.2.1
execnet Version: 2.1.1
The versions are both the lastest.

When I run the command: pytest -k mykey -n 16, I got the error as follows:

INTERNALERROR> E                 raise DumpError(error)
INTERNALERROR> E             execnet.gateway_base.DumpError: string is too long
INTERNALERROR> E           assert False
INTERNALERROR> 

I checked the source code in gateway_base.py and find that when the byte_ > FOUR_BYTE_INT_MAX , there will raise a DumpError.

 def _write_int4(
        self, i: int, error: str = "int must be less than %i" % (FOUR_BYTE_INT_MAX,)
    ) -> None:
        if i > FOUR_BYTE_INT_MAX:
            raise DumpError(error)
        self._write(struct.pack("!i", i))

I tried to add the int8 bytecodes for long string, but it doesn't work.

How should I fix this bug?
