New issue 3115: pyp2.7-v7.2.0 json loads error
https://bitbucket.org/pypy/pypy/issues/3115/pyp27-v720-json-loads-error
zhaoqinghui:
I build pypy2.7-v7.2.0 from source under docker centos7
When I used it to read a simple JSON file, an error occurred, if I use python
or pypy2.7-v6.0.0 there is no problem.
I made a simple test case to reproduce this error
this is the output:
```
[root@14208e811d5c ~]# pypy a.py
<type 'dict'> 2
payment
Traceback (most recent call last):
File "a.py", line 23, in <module>
pp(d)
File "a.py", line 16, in pp
print v
TypeError: 'NoneType' object is not iterable
```
this is my test a.py file:
```python
# -*- coding=utf-8 -*-
import inspect, json
f = open('./a.json')
l = f.read()
f.close()
d = json.loads(l)
print type(d), len(d)
def pp(o):
if isinstance(o, dict):
for k, v in o.items():
print k
print v
pp(v)
if isinstance(o, list):
for x in xrange(len(o)):
print o[x]
pp(d)
```
The a.json used in the test is a little large, so I put it in the attachment
this is my os info in docker :
```
