Summary: bug in rstrip & lstrip
Initial Comment:
quick detail:
<snip>
Python 2.4.2 (#1, Dec 9 2005, 22:48:42)
[GCC 3.3.6 (Gentoo 3.3.6, ssp-3.3.6-1.0, pie-8.7.8)] on
linux2
Type "help", "copyright", "credits" or "license" for
more information.
>>> "net.tpl".rstrip('.tpl')
'ne'
>>> "foo.tpl".rstrip('.tpl')
'foo'
</snip>
I ran the following code to test this:
<snip>
26 - [EMAIL PROTECTED]: ~/pythonBugTest
0> cat testForRStripBug.py
#! /usr/bin/python
for word in
open('/opt/openoffice/share/dict/ooo/en_US.dic', 'r'):
word = word.split('/')[0]
testWord = (word + '.tpl').rstrip('.tpl')
if word != testWord:
print word, testWord
</snip>
And came up with the attached file of incorrect
matches. Out of 62075 words in the en_US.dic, 6864 do
not match. Here is the frequency count of the last
letter of the origional word, the only pattern I could
discern so far:
<snip>
0> ./freqCount.py < run1
{'p': 566, 'l': 2437, 't': 3861}
</snip>
No other letters seem to be clipped. Why this should
be so, I have no idea. I would guess that the error
was in function do_xstrip in
python/trunk/Objects/stringobject.c, but C is not my
strong suit. I will be looking at it further when I
have time, but if anyone knows how to fix this, please
help.
