Pipe Management #1

Closed io-no closed 11 months ago

io-no commented 1 year ago

When the run method of Debugger is used repeatedly in, for example, a bruteforce, the error "too many files open" is encountered. It is hypothesized that this is due to incorrect management of the stdin and stdout PIPEs. The run uses os.execv(path, args) so it is necessary to test and verify if that is the problem. Furthermore, since it is necessary to manage the PIPEs, functions similar to recv and sendline should be implemented to interact directly with the binary.
