[google-appengine] Regexps in app.yaml url for static_dir?
GAE docs [1] on configuring for serving static files say the url param used with static_dir uses regular expression syntax. I can't seem to get this to work. I wanted to let the URLs /stuff/v1/thing.gif, /stuff/v2/thing.gif, etc. all refer to a file thing.gif in my app's /static/stuff directory. Tried like this: - url: /stuff/.*/ static_dir: static/stuff But I only get 404s. (Nothing earlier in app.yaml is interfering either). I ended up converting it to this, which works: - url: /stuff/(.*)/(.*) static_files: static/stuff/\2 upload: static/stuff/(.*) So it works, but the syntax is much more cumbersome. Is regex supposed to work with static_dir, and if so what am I doing wrong (or is this a bug)? Thanks. I should say that I have only tested on this dev_appserver (Mac OS X) so far -- haven't verified this problem in production.

[google-appengine] Re: return a variable value from html form to python
Marzia and others, Thank you for your help. The good news is that I have revised my app to use the google maps methods of passing data around, GDownloadUrl() and it works pretty well on my local machine. The bad news is that when I deployed it to the appspot, it fails immediately. I worried that something was wrong when I tried to upgrade the svn version and got an error message that I don't understand. [3:15am brian~]% cd /Users/brian/googleapps/carpoolfinder/ [3:36am brian~/googleapps/carpoolfinder]% svn status subversion/libsvn_wc/lock.c:377: (apr_err=155007) svn: '.' is not a working copy One bug I know about in the application is that the center marker (pushpin) will not stay off-center from the underlying map if you want it to. While you are building the map, that pin will stay off-center until you go back to the existing map, and there it has centered itself. I would love to find the problem. Another problem occurs if the map builder supplies a ampersand (like walkers pedalers) in the people text field. Also, if the map builder supplies an initial name which begins with any digits, it fails. I will have to learn more Python, I guess to fix these two problems. So, I would like any help you can offer.

[google-appengine] Re: 1 application, multiple datastores
How do you know how the current GAE code actually works? I read the API docs - how do you manage it? I'm not the one asserting that there are hard boundaries between GAE datastores that the GAE run-time can't pierce. Neither am I - I am asserting that there are hard boundaries that you or I can't pierce, and that is a feature of the security architecture. The API docs bear out that assertion. I do *expect* that data partitioning is a DB layer feature, but as I said previously, I don't know that. It is generally believed that GAE is built on top of BigTable, which has a lot of internal Google users. I don't know that all of them can work with only one datastore; I'd guess that several require to access multiple datastores simultaneously. So, if there is a BigTable-level only one datastore and/or can't switch restriction, I'd be very surprised if was universal or could only be pierced by suid applications. I guess one of us will be surprised then :) - I would be surprised if gmail, sites, blogger, picassa, orkut etc. all operated in an open space and avoided data exposure through code implemented in each of those applications. That seems a ludicrous architecture to me - which is my point in this thread I guess. It makes much more sense to me to have the partitioning logic at the DB level (like a standard database tablespace), and for those applications to leverage that. Then they expose API's to access their data at the application level - not use the DB API's. Google does, in fact, expose API's for data access - http://code.google.com/apis/gdata/ - and does not give DB level access to it. So I think just by observing google's current architecture, it makes sense that they wouldn't break with that tradition at the application level for GAE. And not just because its tradition, but because it is rooted in sound architectural principles. Not so fast. Who said anything about application visible tokens? In fact, it could be just change_to_application_userstore, where a userstore is an ordinary GAE datastore. This could easily be written so it doesn't take any parameters from application code, which makes it just as secure as an open datastore call done at process startup. Or, it could support one token, so the application has access to the default datastore and a datastore determined by such a call. Again, that call need not take parameters from application code. I think this is getting away from the 106 proposal now, which states - 'This feature request is about allowing cross app queries using the db APIs only' And regardless, you can easily introduce the cited bug based on your clarification. Simply make the wrong call to 'change_to_datastore', and you still have the exposure problem. When your code is responsible for selecting the datastore, you can introduce the bug. This is fairly obvious. This could easily be written so it doesn't take any parameters from application code, which makes it just as secure as an open datastore call done at process startup. You are still asserting that application code carries the same robustness profile as a platform code. This is clearly not the case. If there are N applications implementing the application API, vs just the platform implementing the platform API, then it is a simple matter of statistics to show that you will get at least N times as many bugs. In fact it will be much more than N, because the volume of testing on the platform will be N times greater, and ther implementation process will be much more rigourous than most application. Without doing the analysis, I would expect the platform fragility (e.g. fragility = defects per month) to decrease exponentially as N increases. Using the application API, I expect fragility would remain roughly constant, and unrelated to N. But there is a hidden bigger probem - if fragility remains constant on a per app basis, then customers see app engine as a minefield - which apps are well implemented? The one they choose could be a broken one. How would they know? This means across the board, the risk of data exposure _from the customer perpsective_ is much worse if partitioning logic is performed in application code. What do you think of the possibility of being able to decide when you deploy your app how strict the data partitioning should be? In the marketplace concept, the customer could be made aware of the strictness of data partitioing when they sign up. My main concern is protecting customer data, and giving customers confidence in the data security of the GAE platform. This is how I read the intent of the original poster as well.

[google-appengine] Getting around the limits of fetching large result sets
I've got several blogs scattered around and use none of them, so I
thought I'd post this here and maybe some of the ideas and methods I'm
using might help other developers using appengine.
Let me preface this with, I've come to the conclusion that appengine
is not the right tool for everyjob, and when you start looking at
needing to do the things I mention below on a regular basis, you might
wish to consider moving back to a traditional server/database
solution, or look for other alternatives to BigTable.
I had two problems, I attacked them two different ways to reach
acceptable solutions.
There was a constraint for both problems that some of you may not be
aware of yet, so I'll explain that first. While the datastore has 1000
limit on fetch(), if you're regularly fetching 1000 entities you are
going to get execution timeouts. Especially if you're doing something
on each of those 1000 requests, like say, deleting them. I've found,
when you're doing a write for every request, 75 is for the most part a
safe number.
Finally, one other piece of information you need is what I'm
developing with.
The latest version of appenginepatch and the django supplied with it,
1.0.2 I believe.
The latest trunk version of gaeutilities (I need to get a new update
out to you all who are using it).
Ok... problems.
Paging.
I needed a nice paging system that would also be lightweight and user
friendly. I read the very interesting article on paging by key, and it
didn't really fit in this instance. keys didn't make for friendly urls
and my paging items are static, I page by a score that can change on
each entity.
My solution was to use the paging library that comes with django. I
run my query, and then page on top of it. Since the scores don't
change every request, I also cache those queries in order to offer
even better performance. I fetch 100 entities for the paging, which
gives me 10 pages of 10, when run through the django pagination
library. To increase the amount of pages, I could fetch more entities.
Deleting more than 1000 records:
My first solution was to create a page that deleted 75 records at a
time, and refresh a whole lot. This was a bit frustrating when I have
of 2 records. The next time I had to do it, I got a little bit
more creative.
First, the view in Django:
def deleteAllStories(request):
''' This method deletes all stories in the database.'''
from google.appengine.ext import db
from fanatasticweb.models import Story
query = db.GqlQuery('SELECT * FROM Story')
results = query.fetch(75)
if len(results) == 75:
more = True
db.delete(results)
if more:
return HttpResponse('More')
else:
return HttpResponse('done')
This view is actually called from ajax request in this view
def deleteAllStoriesV(request):
return render_to_response('deleteall.html', {})
deleteall.html is a simple javascript function that calls the story
deleteview and checks the content. If the content is not done it
refreshes. That way, it will keep running even over the occastional
datastore timeout error you'll encounter.
The main thing I've learned is that when you need to start managing
lots of records, it's possible. Javascript is more than likely going
to be the answer. Javascript will also be useful for avoiding
datastore timeouts in some instances as well. However, when you need
to start creating multiple http requests to manage data on a regular
basis, it may be time to move back to a server with your favorite
database backend in order to be able to process those large
transactions.

[google-appengine] Re: 1 application, multiple datastores
I guess one of us will be surprised then :) - I would be surprised if
gmail, sites, blogger, picassa, orkut etc. all operated in an open
space and avoided data exposure through code implemented in each of
those applications.
If the separation is by name and ordinary file access control, the
code implemented consists of the name of the datastore for the
application plus some application configuration that has to happen
regardless. I'm pretty sure that google thinks that their folks can
open an application-specific datastore name reliably. And, if they
fail, they're talking to a datastore with the wrong structure.
Or, are you thinking that those applications use a different datastore
per external user? (If separate datastore per user is the usage
pattern, bigtable requires far less concurrency support than the
report mentions.)
- and does not give DB level access to it. So I think just by
observing google's current architecture, it makes sense that they
wouldn't break with that tradition at the application level for GAE.
And not just because its tradition, but because it is rooted in sound
architectural principles
What db level access are you talking about? The result of that open
call is used by every other bigtable operation, including all db
operations performed at the datastore. Unless GAE works differently,
the runtime has access to that result.
Not so fast. Who said anything about application visible tokens? In
fact, it could be just change_to_application_userstore, where a
userstore is an ordinary GAE datastore. This could easily be written
so it doesn't take any parameters from application code, which makes
it just as secure as an open datastore call done at process startup.
And regardless, you can easily introduce the cited bug based on your
clarification. Simply make the wrong call to 'change_to_datastore',
and you still have the exposure problem. When your code is
responsible for selecting the datastore, you can introduce the bug.
This is fairly obvious.
Huh? How can you make a wrong call that doesn't have any
parameters?
Here's the application code:
{operations on application-wide datastore}
change_to_application_userstore() # note - no parameters
{operations on user-specific datastore}
{return to user}
The runtime knows what user and the mapping from said user to an
application-specific datastore. The application doesn't specify the
user and doesn't even know the name of the datastore.
There are only two mistakes that the application writer can make -
calling change_to_application_userstore too early or too late.
If the change_to_application_userstore() call is too late, the
application will try to perform some user-specific operations on the
application-wide datastore, but those will likely fail because its
structure is completely different. Note that the application doesn't
have access to any data from the user's datastore at that point.
If the change_to_application_userstore() call is too early, the
application will try to perform some application-generic operations on
the user's datastore, but those will likely fail for the same reason
as above. Moreover, this can't leak user data because the application
only has access to the user's datastore at that point.
You are still asserting that application code carries the same
robustness profile as a platform code.
No, I'm not. I'm pointing out that the platform includes the run-time
and that run-time can provide meaningful services in this area. If
it's already providing related services, and I'm pretty sure that it
is calling open_application_datastore with some application-specific
key on startup, this doesn't change the risk profile.
Do you really want to argue that the platform code in the run-time has
a significantly different robustness profile than platform code
running on a different server? (If I'm correct about it already
providing related services, you're actually arguing about the relative
robustness of related run-time code.) Would platform code running in
a different process on the same machine have yet another robustness
profile?

[google-appengine] Re: Query on partial string
Hi, With App Engine, there is not a great way to do partial string searches. To do prefix matching, which seems to be your use case, you can use inequality filters and the method described here: http://code.google.com/appengine/docs/datastore/queriesandindexes.html Query filters do not have an explicit way to match just part of a string value, but you can fake a prefix match using inequality filters: db.GqlQuery(SELECT * FROM MyModel WHERE prop = :1 AND prop :2, abc, uabc + u\ufffd) This matches every MyModel entity with a string property prop that begins with the characters abc. The unicode string u\ufffd represents the largest possible Unicode character. When the property values are sorted in an index, the values that fall in this range are all of the values that begin with the given prefix. -Marzia On Tue, Jan 6, 2009 at 12:59 AM, chromerunner gau...@gmail.com wrote: A noob question.

[google-appengine] Re: Regexps in app.yaml url for static_dir?
Hi, This is due to the fact that the url parameter for static_dir works differently than that for static_files. The static_dir regex is prefix only with no groups: From static_dir description: url A URL prefix.

Marzia, Could you please provide an example of how one might use a regular expression with static_dir url pattern?

[google-appengine] Re: request: versions accessed by URL param rather than prefix?
Ben, I also am developing FB apps with GAE. I set up a Google Group for this: http://groups.google.com/group/facebook-and-google-app-engine and we've touched on the topic of how to best do app versioning there too. Your proposal is interesting! That group isn't a substitute for this one, but it's a good supplemental place to get all the FB+GAE people together under one virtual roof. Stop by and say hello :) On Jan 5, 12:13 pm, Ben Nevile ben.nev...@gmail.com wrote: Hi, Much of my work with App Engine is on Facebook applications. Facebook acts as a proxy through which all requests flow. Every application registers a callback URL that Facebook directs traffic at. So for instance http://apps.facebook.com/my_application/foo becomes http://my_application.appspot.com/foo One of my favorite GAE features is that I can access and test different versions of my App Engine code. Under most circumstances the URL subdomain-based access (eg, 1.latest.my_application.appspot.com, 2.latest.my_application.appspot.com, etc) is very convenient, but this convention doesn't fit well with Facebook's idea of the fixed callback URL. I can set up a dummy application to access the version of code that I want, but this is A. kludgy and B. inconvenient because all of the social context is absent in the dummy application (other friends using the app, etc.) I would very much like to be able to access different versions of my code using a query parameter. Then I could test my Facebook apps with URLs like http://apps.facebook.com/my_application/foo?APP_VERSION=2 which would be translated into http://my_application.appspot.com/foo?APP_VERSION=2 I'm hoping something like this already possible. If not, consider this a feature request! :) Ben --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: AuthToken for Appengine

[google-appengine] object not iterable
Hi, there,
I've been trying to figure out what is happening with my code, and
after pounding my head against the wall for a while, I thought I'd ask
you guys.
I'm trying to extract some lines containing X= from an inputform.
Here's the portion of code that is giving me trouble:
inputdata = self.request.get('inputdata')
nlines = inputdata.splitlines
xlines = []
for val in nlines:
if val.find('X='):
xlines.append(val)
Here's the error I get:
for val in nlines:
TypeError: 'builtin_function_or_method' object is not iterable
I thought that splitlines would return a list, which should be
iterable, right?

[google-appengine] Crazy Apps account / Google account behavior

Just now, I deleted a *different developer* from the application -- signed in as my Google account. Upon saving, I was redirected to an Unauthorized to view this application page, and much to my dismay, I no longer had access to my application's admin console. Shockingly, however: I now have access to the admin console for my app *with my Google Apps login.* I did not delete or re-invite myself, it just happened by magic. Is there any way to grant access back to my Google account instead of to my Google Apps account without changing my Google account's e-mail address?
