I think you probably need something along the lines of fstat(0, &buf), then check the st_mode. Remember that fifos and chardevs ought to be allowed. ---------------------------------------------------------------------- Comment By: Nick Coghlan (ncoghlan) Date: 2004-11-22 23:32 Message: Logged In: YES user_id=1038590 Python's C main function assumes stdin, stdout and stderr are all valid FILE pointers. A little experimentation on a Linux box should establish what glibc is providing when the input pipe isn't a proper file (probably stdin == NULL given the symptoms, but that's just a guess) A sanity check on stdin should then be possible near the start of the main function. ---------------------------------------------------------------------- Comment By: Nick Coghlan (ncoghlan) Date: 2004-11-22 23:24 Message: Logged In: YES user_id=1038590 Win XP SP 1 - C:\Python24>python < Lib "Access is Denied" ---------------------------------------------------------------------- Comment By: Inyeol Lee (inyeol) Date: 2004-11-05 06:10 Message: Logged In: YES user_id=595280 I did some more test among different versions; 2.4b1/Solaris - segfault 2.3.3/Linux - segfault 2.3.2/Solaris - segfault 2.1.1/Linux - OK 1.5.2/Linux - OK ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=887946&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
