Description Paweł 2019-05-10 18:21:24 UTC

Description of problem:
Webpy stop working after update from python2 to python3

Version-Release number of selected component (if applicable):
python3-webpy-0.40.dev0-20170815gitb725a4f.fc30.noarch

How reproducible:
Run the example application from webpy site http://webpy.org/docs/0.3/tutorial

Steps to Reproduce:
Run python3 code.py

Actual results:
Traceback (most recent call last):
  File "/usr/lib/python3.7/site-packages/web/utils.py", line 526, in take
    yield next(seq)
StopIteration

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "code.py", line 12, in <module>
    app = web.application(urls, globals())
  File "/usr/lib/python3.7/site-packages/web/application.py", line 62, in __init__
    self.init_mapping(mapping)
  File "/usr/lib/python3.7/site-packages/web/application.py", line 130, in init_mapping
    self.mapping = list(utils.group(mapping, 2))
  File "/usr/lib/python3.7/site-packages/web/utils.py", line 531, in group
    x = list(take(seq, size))
RuntimeError: generator raised StopIteration


Expected results:
http://0.0.0.0:8080/

Comment 1 Paweł 2019-09-22 14:56:50 UTC

Nothing has changed in Fedora 31 Beta

Comment 2 Paweł 2019-10-11 19:15:50 UTC

There is the stable version 0.40 https://github.com/webpy/webpy/commit/fa27cc510e39af9c32e015c8daf51023a6e80007
I make a package and this version works fine, but it requires python-cheroot, which is available only in Fedora 31. So I make a python-cheroot package for F30 and everything works fine.

Comment 3 Zhang Huangbin 2019-11-20 14:31:01 UTC

This issue has been fixed in web.py-0.40.
