Anyone have Upload Template Errors w/ Fabric when going from 1.3 to 1.4.6?

[Max Resnick]

Hi Everyone -

I'm working on upgrading from 1.3 to 1.4.6.  While I have no actually issues performing the update with my current site, it seems Fabric Deploy doesn't want to work for me anymore.

I had modified the fabfile.py so that it would deploy to a staging and production.  I also modified it so that the project's database name and project name could be different.  It's had worked just fine, but after upgrading to 1.4.6 it seems to have no love for me anymore. :-(

I've tried with both the as release fabfile and my modifications.  both happily preform 'fab all' but spit out the following traceback after I attempt to apply 'fab deploy'

If it helps here: my repo https://github.com/grumps/ofmax

If anyone has a suggest on how to can work on debugging I'd love the advise.  Thanks.

I've tried to debug but seems it a bit beyond me at the moment:

It's probably related to this change:

https://github.com/stephenmcd/mezzanine/commit/e5d55432d06b08ef2a19c7db0bab03ba1c03668a

It tries to escape any percentages in deploy templates that don't look like variable substitution, eg turn % into %% if it doesn't look like %(this)s

Your best bet in debugging it would be to wrap the upload_template call in try/catch, then look at which template it's failing on:

https://github.com/grumps/ofmax/blob/master/fabfile.py#L225

Would become:

try:

    upload_template(local_path, remote_path, env, use_sudo=True, backup=False)

except:

    print local_path, env

Hi Stephen -

Thanks for your continual responses and work on the Mezzanine.  I'll give it a shot and provide my findings. 

thanks!

I've discovered it was my nginx.conf ... re-write that was causing the issue.

rewrite ^(.*) http://%(live_host)$1 permanent

I'm guessing it's one of the special characters?  Maybe I'm doing the re-write correctly? NGINX isn't complaining...?

So anyway a big thanks to Stephen for getting my started on debugging.
