When spawning a process, stdio file descriptors can be configured to be ignored, which basically means that they'll be closed. Currently this is done by literally closing the file descriptors in the child, but this can have adverse side effects if the child process then opens a new file descriptor, assigning it to a stdio number. To work around the problems of the child, this commit alters the process spawning code to map stdio fds to /dev/null on unix (and a similar equivalent on windows) when they are specified as being ignored. This should allow spawned programs to have more expected behavior when opening new files. Closes #14456 |
