New submission from Nick Coghlan <ncogh...@gmail.com>: subprocess.check_output() is nice, but doesn't help if you want to process the piped data line-by-line.
Currently, that means you have to do the full Popen dance if you want access to each line of output as it becomes available. This RFE is for a subprocess.iter_output() module level helper that: 1. Starts the subprocess 2. Yield the individual lines of output as they are produced by the subprocess 3. Cleans up (including checking for errors) at the end This biggest challenge I have noticed so far in exploring this is how to handle timeouts on Windows - on Unix, select.select() can do the job, but that won't handle pipes in the Windows case. ---------- components: Library (Lib) messages: 149210 nosy: ncoghlan priority: normal severity: normal stage: needs patch status: open title: Add subprocess.iter_output() convenience function type: feature request versions: Python 3.3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13578> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
