Kay runserver breaks with 1.6.0

[someone1]

I recently upgraded to the AppEngine SDK 1.6.0 and when I try to run
the server I get the following:

C:\...\src>c:\Python27\python.exe manage.py runserver
Running on Kay-1.1.1
WARNING 2011-11-10 12:10:18,825 rdbms_mysqldb.py:90] The rdbms API is
not available because the MySQLdb library could not be loaded.
Traceback (most recent call last):

get_appid())
File "C:\...\src\kay\misc\__init__.py", line 21, in get_appid
appconfig, unused = dev_appserver.LoadAppConfig(PROJECT_DIR, {})
ValueError: too many values to unpack

It worked prior to the upgrade so I'm not sure what's wrong.

Sorry about that. I'll release a new version shortly, but for a time being, please re-write kay.misc.__init__.py as follows:

    appconfig, matcher, from_cache = dev_appserver.LoadAppConfig(PROJECT_DIR, {})

Thanks,

Thanks gmist!

I'm going to release a new version dedicated to python27 runtime.

For those who wants to use SDK-1.6.0 with python2.5 runtime, please use a patch from gmist.

I've just created a branch for py27 runtime at:

http://code.google.com/p/kay-framework/source/browse/?name=py27

Currently, tests don't work properly and I'm looking into it. I want local unit tests to work properly at least.

Thanks,

Hello Takashi,

Thanks for your continued support!

I tried your changes and can get the dev server to run properly now, however, I've noticed some issues:

- I downloaded your py27 branch and found that jinja2utils is still required by a preparser in the kay\management
- Since you removed jinja2 from kay\libs, it requires we have the jinja2 library installed in our python setup. Its not included with GAE SDK 1.6.0 or Python 2.7.2 (I'm using Windows 7)
- When launching from kay, loading a page complains about missing webapp2, I had to copy this to my c:\py27\Lib folder from the GAE directory in order to get it to work (launching directly from the appcfg shipped with 1.6.0 fixes that issue).

I think there are still some bugs that need to be worked out on the py27 branch or additional setup instructions included.

Anyway, I hope this helps. I've got my setup to work but it wasn't as simple as "plug'n'play"

If there's anything I can do to help, let me know. I really do enjoy using KAY :)

Thanks,
Prateek

hi Prateek, how did you resolved the jinja2utils in preparse? Did you just recovered the old module?

[Paolo Casciello]

I respond to myself, just commented out the lines using it:

I re-included the jinja2utils package as its required to pre-compile the templates before deployment. You shouldn't comment it out but add the package back so that in production your running off precompiled templates versus having to parse it (assuming my knowledge of how KAY's implementation is meant to work is correct).

Yes, your solution is correct.

now i don't need to go on production with the py27 branch :)

[Takashi Matsuo]

Why I'm going to remove jinja2 preparse is that python2.7 runtime can use bytecode, so jinja2 can use bytecode cache, which is not available with python2.5 runtime. I've just committed a change at:

http://code.google.com/p/kay-framework/source/detail?r=ed3ad77a6afb508f190208886c3e9a844fa0a47a&name=py27

What do you guys think?

[Gopal Patel]

right.

you can also completely remove jinja lib from source tree too, since it is also available via sdk too.

[Paolo Casciello]

gops, it is removed. We're talking about the py27 branch.

to develop with gae + kay in py27 you need jinja2 installed on your system

[Paolo Casciello]

With latest updates it works directly after checkout.

It's true, as stated in ( http://code.google.com/appengine/docs/python/python27/newin27.html ), Jinja2 can create bytecodes.

In http://code.google.com/appengine/docs/python/python27/using27.html#Configuring_Libraries is advised to include also markupsafe and setuptools so we could add them in the app.yaml base template.
