New submission from Donald Wallace Rouse II <python-bugs-as92...@dwr2.org>:
Python 2.7 programs crash on startup due to a defective third-party package
installed in site-packages.
starting python 2.7 yields the following error message:
Traceback (most recent call last):
File "/usr/lib64/python2.7/site.py", line 554, in <module>
main()
File "/usr/lib64/python2.7/site.py", line 537, in main
known_paths = addsitepackages(known_paths)
File "/usr/lib64/python2.7/site.py", line 316, in addsitepackages
addsitedir(sitedir, known_paths)
File "/usr/lib64/python2.7/site.py", line 192, in addsitedir
addpackage(sitedir, name, known_paths)
File "/usr/lib64/python2.7/site.py", line 162, in addpackage
exec line
File "<string>", line 1, in <module>
KeyError: 'zope'
A similar message appears when starting python2.7 interactively, but it then
proceeds to the prompt (doesn't crash).
In the file .../python2.7/site.py, at about line 162, in the function
"addpackage", you have an
unprotected "exec" line:
if line.startswith(("import ", "import\t")):
exec line
If the execution of the line fails, python generates an uncaught exception.
This places python at the mercy of bugs in third-party software.
The "exec" line should be bracketed by "try/except" to catch such errors:
if line.startswith(("import ", "import\t")):
try:
exec line
except:
pass
continue
Note 1: I am not sure whether this is a Distutils bug or Distutils2 bug (or
even something else like "Extension Modules"), so I'm filing it under
Distutils2. If this is incorrect, please forward to the proper place. Thanks.
Note 2: Here is where I initially reported this problem:
