backports.configparser.InterpolationSyntaxError: '%' must be followed by '%' or '(', found: '%Y-%m-%d %H:%M:%S:%F %s: %t'

[bugcy013]

Hi Guys,

When I try to run circusd in windows server 2008rc2. I am getting this exception. I am using Python 2.7.15

backports.configparser.InterpolationSyntaxError: '%' must be followed by '%' or '(', found: '%Y-%m-%d %H:%M:%S:%F %s: %t'

PS C:\tech\tech_recorder> circusd.exe tech.cfg

Did this ever get resolved? I am seeing that in 0.16.1 n a fresh build on Mac OS X, triggered by this line:

tdout_stream.time_format = %Y-%m-%d %H:%M:%S [webapp]

btw, I do not see the % in your text! :)

[biozz]

The quick solution is to interpolate % with another %:

stdout_stream.time_format = %%Y-%%m-%%d %%H:%%M:%%S 

What I found was that if you change ConfigParser to RawConfigParser it works without extra % interpolation. But I am not sure about the consequences and will try to find that out.

https://github.com/circus-tent/circus/blob/2bedab09145a4959ce02b93777dbffbce56edd8e/circus/util.py#L755

I also notice that documentation for that is not correct, so we will have to decide: use the extra interpolation or change the config parser.
