New submission from telmich <nico-bugs.python....@schottelius.org>: Hello,
pressing ctrl-c or having sigint delivered to the python process in its startup phase results in random tracebacks displayed. This is related to issue3137, but actually happening in Python 3.2.2 on archlinux. We noticed this during development of the cdist project (http://www.nico.schottelius.org/software/cdist/), where we call a shell via subprocess.check_call() which calls us again (under a different name and thus different behaviour. So the call chain is like this: cdist => /bin/sh -e script => cdist_as_different_name (i.e. __file) A simple test case to reproduce the problem needs the two files caller.py and shellpart.sh in a directory: % ln -s caller.py __testpython % chmod a+x * % ./caller.py Indirect child being called Indirect child being called Indirect child being called Indirect child being called ^Ccaught signint in parent Traceback (most recent call last): File "/usr/lib/python3.2/site.py", line 58, in <module> import traceback File "/usr/lib/python3.2/traceback.py", line 3, in <module> import linecache File "/usr/lib/python3.2/linecache.py", line 10, in <module> import tokenize File "/usr/lib/python3.2/tokenize.py", line 28, in <module> import re File "/usr/lib/python3.2/re.py", line 121, in <module> [10:02] brief:python-traceback-test% import functools File "/usr/lib/python3.2/functools.py", line 2, in <module> """ KeyboardInterrupt Pressing Ctrl-C results in various different tracebacks and I don't see any way to catch the SIGINT reliably currently, as the code executed seems to be *before* my code is being executed. There is another related bug at debian that references the same problem: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=652926 ---------- files: shellpart.sh messages: 155152 nosy: telmich priority: normal severity: normal status: open title: SIGINT (Ctrl-C) not caught at startup type: crash versions: Python 3.2 Added file: http://bugs.python.org/file24755/shellpart.sh _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14228> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
