Category: Python Library Group: Python 2.4 >Status: Open Resolution: None Priority: 5 Private: No Submitted By: Daniel Farina (drfarina) Assigned to: Nobody/Anonymous (nobody) Summary: urllib2 does local import of tokenize.py Initial Comment: urllib2 may do a relative import of tokenize.py, which can cause it to function abnormally when the user has a file named "tokenizer.py" in the directory as a script that utilizes urllib2. The attached tarball has a shell script called "showme.sh" that will give standard input to afile.py, which contains two import statements and nothing else. Code in the neighboring tokenize.py will be executed, resulting in printing those lines to standard output. Expected behavior: no code in tokenize.py should be executed. Reproducible on Ubuntu 6.10 ---------------------------------------------------------------------- >Comment By: Daniel Farina (drfarina) Date: 2006-11-03 10:26 Message: Logged In: YES user_id=425987 I have a fresh Ubuntu Edgy install (although my home directory is quite old and persistent). I have installed the Python 2.5 package, but am not using it in this case. You are correct, urllib2 doesn't contain the import. I still get the behavior on my machine. On my machine, the following interaction takes place: [EMAIL PROTECTED]:~/urllib2_bug$ ls afile.py show.sh tokenize.py tokenize.pyc [EMAIL PROTECTED]:~/urllib2_bug$ ./show.sh import sys import urllib2 [EMAIL PROTECTED]:~/urllib2_bug$ more show.sh #!/bin/sh cat afile.py | python afile.py [EMAIL PROTECTED]:~/urllib2_bug$ more afile.py import sys import urllib2 [EMAIL PROTECTED]:~/urllib2_bug$ As we can see from the contents of afile.py, it shouldn't be printing anything. ---------------------------------------------------------------------- Comment By: Georg Brandl (gbrandl) Date: 2006-11-03 08:20 Message: Logged In: YES user_id=849994 I can't reproduce that here with your example code, and there's also no mention of "tokenize" in urllib2.py. In any case, "import tokenize" is not a relative import, and it's the only way a standard library module can import another standard library module. That this can interfere with user-defined modules is known and must be worked around by not naming them like builtin modules. ---------------------------------------------------------------------- Comment By: Daniel Farina (drfarina) Date: 2006-11-02 12:16 Message: Logged In: YES user_id=425987 Yet another typo: the script is called "show.sh" It's the only shell script in there, so no fear. ---------------------------------------------------------------------- Comment By: Daniel Farina (drfarina) Date: 2006-11-02 12:11 Message: Logged In: YES user_id=425987 Typo in the above: "tokenizer.py" should just be "tokenize.py" ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1589480&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
