[issue16734] Delay interpreter startup phase until script is read
Charles-François Natali added the comment: I may be missing something, but nothing's wrong here. When you start a subprocess, the child process keeps running (in background). If you want to wait for its termination, just use p.wait() or p.communicate(). -- nosy: +neologix ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16734 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Serhiy Storchaka added the comment: You should use some kind of inter-process communication to synchronize your processes. In particular, for get rid of a temporary script file you can either send script via pipe: p = Popen([sys.executable], stdin=PIPE) p.stdin.write(longscript) or use it as a program argument: p = Popen([sys.executable, '-c', longscript]) -- nosy: +serhiy.storchaka ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16734 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue16734] Delay interpreter startup phase until script is read
New submission from anatoly techtonik: Currently, when interpreter is launched it returns immediately to parent process without waiting to read the entrypoint script. This causes problem when you need to remove this script after executing. Is it possible to delay return to child process until the entrypoint script is read?
