It looks fine to me, too. The handlers entry is identical to what I've got going fine in my projects. It might be something fiddly. Do you have a newline character at the end of the file? Are you using a funky character? Try retyping it in by hand (no copy-n-paste).

Looks to me like there's three spaces in front of "static_dir: static". Try removing one of the spaces so that there are only two.

[google-appengine] How-To Do Paging on App Engine
I just looked into the artile "How-To Do Paging on App Engine" in the App Engine archive and I think that the Contributor object seems to me like an overkill for that kind of problem. If you want to prevent multiple 'created' values to be equal you could just append a random number at the end of the 'created' value. This way you can do the pagination as describe in the article while minimizing the propability of multiple entries having the same 'created' value and without having to do this complicated Contributor stuff and the computational expensive user-email-md5 obfuscation.

[google-appengine] Re: handling timezones - problem using sample code
I appreciate the pointer, but I've read the documentation and it, frankly, sucks. It's really dismaying that a company with the resources of Google is doing such a piss-poor job at delivering this toolkit. First of all, this simple thing should be trivial to solve - one line of code. The point of GAE is that it's supposed to be easy, right? Second, you shouldn't have to read 3 or 4 incomplete, poorly written, disjoint pieces of documentation to figure something out. It's not like this is a free service. Google really ought to ask themselves whether they want to do this and then look at the documentation Adobe, for example, provides for their tools. Even in Beta the Flex documentation and tools were orders of magnitude better than what Google provides. This is like, read the GAE "documentation", then read the django docs and figure out what does and does not apply, then read the docs for some python library, but we don't support it so you can't use it. Then write your own version of the python library and maybe you can do this thing that would be one line of code in Django or Java or any good toolkit. Ok two lines of code if you count the import statements.

[google-appengine] Changine an existing entity
I have been working with Appengine for 3 months and this is my first post,
but I have read with interest correspondence in this group. Thanks for all
the valuable information.
My original problem was simple, or so I thought. I wanted to increment a
value and return it to the datastore. However, the value I do increment does
not return to the datastore incremented. The code below is my attempt to
find the problem, which I do but cannot explain or resolve.
I iterate over a "list". In a selected entity I attempt to increment the
"entrycount". I log the before and after incremented value. Works as
expected. However, when I am done with the first interation, I iterate over
the "list" again to review the "entrycount". As you can see by the log
below, the count on Alex has retuned to zero. How is this possible? What am
I missing?
for lst in list:
if self.request.get(lst.title):
logging.error('Title: '+lst.title+str(lst.entrycount))
contacts.groups.append(lst.title)
lst.entrycount = lst.entrycount+1
logging.error('Title: '+lst.title+str(lst.entrycount))
else:
logging.error('Owner: '+'No title read'+str(lst.entrycount))
for lst in list:
logging.error('Title: '+lst.title+str(lst.entrycount))
db.put(list)
contacts.put()
util.flushContacts()
return True
The ERROR prefix is meaningless. That is just my log output.

[google-appengine] Re: Application registration issue
Hi, If I had to guess what happened, it was that you were logged in to a Google Account, and were also logged in to a Google Apps account at the same time. I agree it's pretty frustrating and confusing (for us to!), but here goes my best attempt at an explanation. Google Accounts and Google Apps authenticate against different systems, so you can be logged in to one Google Account and multiple Google Apps accounts (for different domains) all at the same time. Usually this isn't an issue because most services use either Google Apps or Google Accounts, but not both. Google App Engine allows both types of accounts with our system, and we serve different authentication pages for an account if you go to http://appengine.google.com/ or http://appengine.google.com/a/YOURDOMAIN when you sign in to App Engine. However, after you are authenticated, when you sign up for an app id we check who you are and say assign the app to 'x...@y.com' (more or less). Most of the time, if 'x...@y.com' is a Google Apps account, we'll assign the app to the Google Apps account (even if you logged in to Google Accounts). Like I said, it's pretty confusing, which is why we suggest not using accounts with App Engine that are both Google Accounts and Google Apps accounts: http://code.google.com/appengine/articles/auth.html It generally avoids this confusion. Let me know if this clears up what happened, and if you need additional help with assigning the correct admins to the correct apps. -Marzia On Sat, Jan 24, 2009 at 1:17 PM, Alistair wrote: > > Well I just logged into http://appengine.google.com/a/0gravity.co.uk > and saw the application sitting there.

[google-appengine] Re: Why can't I sign up Adsense for my Google App Engine application?
Hi, To be honest, I am not familiar with configuring AdSense accounts, but it was my understand (and this could be incorrect), that you only had to specify a URL with AdSense if you wanted the site to serve targeted ads for your site, or the site to work behind login. But I thought that you could still serve AdSense off of any domain with the appropriate AdSense code.

Hi, There are a couple of reliable ways to do paging with App Engine for arbitrarily sized data sets, both of which are discussed in this article: http://code.google.com/appengine/articles/paging.html And the corresponding sample code: http://code.google.com/p/google-app-engine-samples/source/browse/#svn/trunk/paging The easiest way is to just use key paging, if key ordering is sufficient for your paging needs.

[google-appengine] Config server to sent mail to an APP Mail
I have a domain with an email in a server; all messages can be received and sent using MX configuration. Now I have another domain that don’t use MX and APP in the same server, and when I use these email, I got an error 5.1.1 recipient address rejected: User unknown in virtual mailbox table. Studding the problem I suppose that it’s because all the email accounts are not configured in that server, are in APP of Google, when I send the email, the server don’t find the account.

[google-appengine] Re: two paging problems
Hi,
This may not work for your particular use case, but you can use an
equality filter in conjunction with the key filter, so instead of
something like:
suggestions = Suggestion.all().filter('__key__ >=',
bookmark).order("__key__").fetch(PAGESIZE+1)
you could do:
suggestions = Suggestion.all().filter('title =',
VALUE).filter('__key__ >=',
bookmark).order("__key__").fetch(PAGESIZE+1)
Which would at least allow users to query on a small subset of values
(those that specifically equal a property) and still allow paging on
the results.

[google-appengine] Re: Django's manage.py shell and local Interactive Development Console
Actually, it's the interaction between the "manage.py shell" and the Development Console's "Datastore Viewer" that I'm getting the odd behavior on. The "interactive console" does not have the proper django context setup so it's not really usable for django interaction as far as I can tell (and so i tried "manage.py shell" for interactive python access to the datastore).

[google-appengine] Re: verification & uploading, spurious account mixing
Hi, First, if you are having problems verifying an account with Google App Engine, please just fill out the SMS issues form: http://appengine.google.com/waitlist/sms_issues To clarify some issues here, Google App Engine is a distinct product from Google Apps. However, Google App Engine offers developers the ability to use Google Apps authentication along with the applications they build. To allow a user to upload application versions to any App Engine app, all you need to do is add that person as a developer here: http://appengine.google.com/permissions?&app_id=YOURAPPID Once they have confirmed the request via a link sent in an email, that person can upload an application. Email accounts invited to develop an application do not need to be verified via SMS unless those developers also want to create new applications. Another point of confusion is that being a Google Apps admin account has no impact on being an admin of a Google App Engine application. You must explicitly invite people to be developers of each Google App Engine app you wish them to have permission to upload applications versions to (using the above link for each app id). Once an account has access to upload an app, doing so is very straight forward, just call appcfg.py and enter your email address and password: http://code.google.com/appengine/docs/python/tools/uploadinganapp.html -Marzia On Fri, Jan 23, 2009 at 9:25 PM, cincinnatus wrote: > > I have two testing domains, one verified and one not.

[google-appengine] Re: App Engine, Eclipse and Pydev Great but how to get breakpoints???
Comments anyone??? Per the Pydev developer on his support site: Unfortunately, I don't know enough of the App Engine to say the actual problem, so, I have to get it, create an account and do an example to know what can be failing there... A common problem in web frameworks (django, turbogears, etc) is that there is usually a 2nd process spawned to run things when your files change, so, for the debugger to work properly you have to run with -- no-reload (or some option close to it), or use the remote debugger http://fabioz.com/pydev/manual_adv_remote_debugger.html ), but I'm not sure if that's true for the app engine. The problem with the post vs the bug is that I can forget to answer you (as I won't be able to go on and get an app engine example running here right now).

[google-appengine] ClientLogin for App Engine and HOSTED_OR_GOOGLE setting
I'm trying to login to my version simple test app using this script:
http://dalelane.co.uk/blog/?p=303
The test app just displays "Hello world" when you are logged in like
this:
http://restapitests.appspot.com/
def get(self):
user = users.get_current_user()
if user:
self.response.out.write('Hello world!')
else:
self.redirect(users.create_login_url('/'), False)
I'm testing with two different accounts. "je...@hogbaysoftware.com"
was created through Google Apps. And "jesse.grosj...@gmail.com" was
created through google. If I access my app through a web browser then
I can login and see "Hello world" using either account. But if I login
via the ClientLogin, token, ACSID cookie rout then I have some
problems based on the "accountType" key that I post to ClientLogin.
If I use HOSTED_OR_GOOGLE then only my account
"jesse.grosj...@gmail.com" can login and see "Hello world"
If I use GOOGLE then both accounts can login and see "Hello world"
If I use HOSTED then neither account can login
This seems really odd to me because in all the examples people seem to
be using HOSTED_OR_GOOGLE, and that's documented as the choice that
will accept all accounts. Can someone tell me why I have to use
accountType GOOGLE so that I can login with either of my accounts,
instead of using HOSTED_OR_GOOGLE?
Thanks for any help.
Jesse

[google-appengine] Re: asking for the python debugger
Well, what do you mean by "output in the shell" ?
Do you see pdb prompt in terminal?
>From pdb prompt you may inspect objects by typing "pp "
If you want to print something to terminal during program execution,
you probably have to send it to the standard error like this:
import sys;sys.stderr.write('Hello!')
It depends on the way how you executed dev_appserver.py and if you did
any output redirections.
I would use logging module instead...
---
If you are on OSX, you may try to run this project and debug main():
http://github.com/darwin/drydrop/tree/master
add these lines into main() in drydrop_handler.py
import sys;sys.stderr.write('Hello from main!')
import drydrop.lib.dbg;drydrop.lib.dbg.b()
run:
rake edge_gae
rake
it starts dev server in new terminal window with title "DryApp",
go to http://localhost:8080/
and then see "DryApp" terminal tab
debugger works even without patching GAE SDK
hmm, strange
anyway, this may be good example, I've just tested it here on my machine

[google-appengine] Announcement: gaeutilities 1.1.2
gaeutilities - http://gaeutilities.appspot.com/ - release 1.1.2 is now out. It is strongly recommended anyone using the session class upgrade to this version. 1 critical and 1 important bug is solved in this release. Also there is a marginal performance increase by being able to configure how often the last_activity field is updated, removing the need to have a put on every request. 1.1.2 - session: Added last_activity_update variable to set an interval for which last_activity needs to be updated. It defaults to 60 seconds. This means a put is not required every request which should increase performance. - session: Refactored based on a contribution from Jeremy Awon optimizing the class initialization. - session: Bug found in the process to clear old sessions that was deleting data it shouldn't be. This was the cause of the mysterious missing session data bug. Thank you pant.lalit - session: Bug fixed where clean_check_percent was being ignored. - session: Some tweaks done to delete_all_session(), though this feature shouldn't be considered complete yet. Needs more testing. More performance improvements are planned for the 1.1.3 release which will be coming soon. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] GAE datastore insertion rate
I've developed a service on GAE, that takes small POSTS (160 bytes) from devices in the field, and stores them into the datastore. A device will send a package of 4 notes once a minute, during operational hours. These notes are unpacked and placed into the datastore (one entity Note). I started a simple benchmark of 1,000 devices. To my surprise, I got a bunch of these errors: "too much contention on these datastore entities. please try again." 1000 devices * 4 notes per minute gives me a rate of approximately 67 inserts per second. Is this an issue with the 'beta', or is this a reality of the datastore? Thank you, -David Story BTW, I was using approximately 10 CPU seconds per second during this run. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: Video conversion with GAE
That's a big no-no on AppEngine. AppEngine is designed for lightweight HTTP requests. Video transcoding is a big heavy bag of number crunching. VideoEgg's original business model was to do this sort of transcoding, but I believe they are out of that business. I think Blip.tv will help you, so long as your videos are appropriate to post on their service. Your other option is to set up a single-purpose server somewhere that runs ffmpeg on each video. You'd send it the raw files, and it would send you and email or something when they were ready. Since you're already learning AWS, you could do ffmpeg on EC2. One of the things I like about AppEngine is you don't have to be a systems admin to get a good setup going. Unfortunately, AWS is more system- adminie.

[google-appengine] Re: Having problems posting to the AppEngine Cookbook
Usability question: How do you feel about comments being listed in reverse-chronological order (as they are now) versus forward-chronological order (the standard for most comments/forums/threaded discussions)? It's kind of nice to have the most recent (hopefully most relevant) discussions bubble up nearest to the article. Then again, it is inconsistent with user expectations from the greater Web. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: GAE datastore insertion rate
I created a root group entity for each Device. I modified the Note entity to use it's Device as its parent. device = Device.get_by_key_name(name) if device != None: for n in noteList: note = Note(parent=device, n) note.put() Now I'm seeing this error: The API call datastore_v3.Get() required more quota than is available. According to my interpretation of Brett, in that video, "get by key is very fast". Again I ask, is this a limit of the beta, or a reality of the datastore? -David Story --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

Like this: device = Device.get_by_key_name(name) if device: notes = [Note(parent=device, n) for n in noteList] db.put(notes) That should do the writes in parallel, which should increase your throughput. > Now I'm seeing this error: > The API call datastore_v3.Get() required more quota than is available. Otherwise, it sounds like you're hitting quota limits, which is probably related to the way you're running your load test. How many requests per second were you issuing? Approximately how many Note entities were you inserting per second? 10 CPU seconds per second doesn't make this quite clear. We have short-term quota limits in place for handling very large bursts of usage. More detail is here: http://code.google.com/appengine/docs/quotas.html#Burst_Limits You may be hitting one of these burst quotas because of your load. Another possibility is that you're using key_names for your Device and Note instances that are sequential or lexically "close", which could cause hotspots in your Bigtable access patterns. When you run the load test, in what order are you writing Notes to Devices? -Brett --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
