When I deploy my app on app engine the gallery works ( http://mark-smith-app.appspot.com/projects/ ) but it doesn’t work offline..
I want to get my gallery working with the following command:
C:\Python27\python.exe "C:/Program Files/Google/google_appengine/dev_appserver.py" .
When I open chrome and go to 127.0.0.1/projects/ it shows the gallery but only the first image displays, the rest of the images in the gallery are “black”.
I downloaded the gallery from http://www.awkwardgroup.com/sandbox/awkward-showcase-a-jquery-plugin/
The gallery I downloaded comes with an example index4.html which works when I open it with chrome.
I copied everything from index4.html into my google app engines projects.html and changed made a static directory for the css, js and images.
here is app.yaml:
application: mark-smith-app
version: 1
runtime: python27
api_version: 1
threadsafe: true
handlers:
- url: /stylesheets
static_dir: stylesheets
- url: /images
static_dir: images
- url: /.*
script: main.app
libraries:
- name: jinja2
version: latest
I also went to 127.0.0.1/projects and went “view source” and copied it into html1.txt
I also copied “view source” from index4.html into html2.txt
I got the following results from the following python differ script:
f1 = open('html1.txt')
f2 = open('html2.txt')
from difflib import ndiff,IS_CHARACTER_JUNK
delta = ndiff([i.strip()+"\n" for i in f1],[i.strip()+"\n" for i in f2])
for line in delta:
print line,
outputs:
*** Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on win32. ***

Logs are below: I run the app, click the projects link to go to the /projects/ page, where the gallery correctly displays 05.jpg Then you can see me clicking across to 01 and 04.jpg, then back to 05.jpg (05.jpg is the only one that isn’t blacked out). Thumbnails work though.

It’s nearly impossible to tell from the information given what the precise cause is, but there is one big difference between the development server and the production server: the development server is single-threaded, so if it is not possible for a request to finish before the requests for the images come in, eventually the browsers will time out and no-longer try to render the images.
It would be useful to see the logs that are written out by the development server.
