Description Michal Hlavinka 2015-07-13 17:05:15 UTC 
Created attachment 1051473 [details]
reproducer.py

Description of problem:
bs4 4.4.0 update breaks our script that works with previous version 4.3.2-3

Version-Release number of selected component (if applicable):
python3-beautifulsoup4-4.4.0-1.fc22.noarch

How reproducible:
always

Steps to Reproduce:
1. ./reproducer.py
2.
3.

Actual results:

dst= <class 'bs4.element.Tag'> 
 src1= <class 'bs4.element.Tag'>
dst= <class 'bs4.element.Tag'> 
 src2= <class 'bs4.element.Tag'>
dst= <class 'bs4.element.Tag'> 
 src3= <class 'NoneType'>
Traceback (most recent call last):
  File "./reproducer.py", line 84, in <module>
    update_html_template(html, 3) # regression
  File "./reproducer.py", line 75, in update_html_template
    dst.insert(0, src3)
  File "/usr/lib/python3.4/site-packages/bs4/element.py", line 317, in insert
    new_child.parent = self
AttributeError: 'NoneType' object has no attribute 'parent'

src3 find call fails which causes this backtrace

Expected results:
dst= <class 'bs4.element.Tag'> 
 src1= <class 'bs4.element.Tag'>
dst= <class 'bs4.element.Tag'> 
 src2= <class 'bs4.element.Tag'>
dst= <class 'bs4.element.Tag'> 
 src3= <class 'bs4.element.Tag'>
DONE
<class 'bs4.BeautifulSoup'>
