Actually it happens even if threadsafe : no. Just not as often.

[google-appengine] Java Source Code for GAE libraries

[Alan Czajkowski]

Where can I find source code for the following libraries:
appengine-remote-api.jar
appengine-tools-api.jar
(or any other GAE library other than appengine-api-1.0-sdk-x.y.z.jar)

Thanks,

[google-appengine] Re: Google App Engine SDK 1.7.7 is now available!

[Panjie Setiawan Wicaksono]

Hi, with 1.7.7 python SDK i no longer can visit the local endpoint api 
explorer.
Before, i'd visit http://localhost:8080/_ah/api/explorer then redirected to 
https://developers.google.com/apis-explorer/?base=http://localhost:8080/_ah/api#p/
 and 
i can explore my local endpoint api from there.
But now the apis-explorer won't load the local endpoint api, instead it is 
now redirecting me to the front 
https://developers.google.com/apis-explorer/#p/ page.
If i deploy the app first, i can load the apis-explorer just fine (from the 
deployed app endpoint).
I don't know if this is sdk related, but before (with 1.7.6) the 
apis-explorer can be loaded from local development server.

[google-appengine] ImportError on SDK 1.7.7

[Christoph Gerneth]

I get an ImportError on my local dev_appserver.
i have set up a virtualenv, pip-installed all dependent packages, symlinked 
from source directory to the site-packacke dir and even when i activate the 
virtualenv, the import of these modules works just fine:

(TimeTable)christoph@xps:~/workspace/TimeTable/src$ python
Python 2.7.3 (default, Aug  1 2012, 05:14:39) 
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import icalendar
>>> 
>>> help(icalendar)

the 'help' shows, that the source of the modules points to the following 
path:
*
/home/christoph/workspace/TimeTable/local/lib/python2.7/site-packages/icalendar/__init__.py
*
Check!
 
but when i try to run dev_appserver.py, i always get following error:

There is probably a very simple solution to this problem.

To clarify, we're going to release a minor update for 1.7.7. For the
meantime, you can re-jar the file as follows:

cd to the working directory
$ jar xf somewhere\appengine-java-sdk-1.7.7\lib\user\
appengine-api-1.0-sdk-1.7.7.**jar
$ jar cfm somewhere\appengine-api-1.0-sdk-1.7.7.**jar META-INF/MANIFEST.MF *
and replace the old jar with the newly created one.

Sorry for the inconvenience.

 I'm on Windows 7 x64 with latest GAE and Java 7 SDK and
 the appengine-api-1.0-sdk-1.7.**7.**jar is 30.6MB big.

 Thanx for your help.

Re: [google-appengine] Re: Google App Engine SDK 1.7.7 is now available!

[Ludovic Champenois]

Hi,
We are tracking this issue internally...Only on windows, and if your app is 
using some JSP right?
It's a combination of 2 things: the api jar becoming too big (we will 
compress it soon), and the jspc compiler keeping a lock on the files in the 
jspc classpath, making the api jar not deletable (we do not need to upload 
it to the runtime server)... Windows file locking system makes the locked 
file non deletable...
Until we push a new SDK, the only workaround would be for you to modify 
your local SDK this way:
1/ unjar the impacted jar.
2/ rejar it with the jar command default (i.e compression) and making sure 
you keep all the META-INF manifest (using the m flag) content in the new 
jar. It contains critical info for the processing.
This will workaround the issue, while waiting for a new push.

[google-appengine] security issue (strange behavior)

[@Mlaynes]

my page : http://igguestbook.appspot.com/
( a guestbook with some of geolocation and OAuth2.0 Authrization & 
Authentication )

over one month I have "attacks" of robots or hackers who type sexual ads on 
my guestbook I'm trying to control ...

I have restricted the submits on my page from the front-side (javascript) 
.. and from  the server side (GAE-Java backend) .. but the ads are still 
trying to write on my page .. and now, save ads "empty" ..

. and now my page sometimes throws: Error: Server Error

sometimes by the attacks, my page has exceeded  "Datastore Read Operation" 
quota .. but I see that now hasn't exceeded .. But still throw : "Error : 
Server Error"








any idea ?

best regards

@Mlaynes

Re: [google-appengine] Text

[Moises Belchin]

You can use Python string interpolation

new_text = '%s %s' % (text1, text2)

Please be more specific in your questions!

It depends on the language. For example, in Python
*new_string = string1 + string2*
