[google-appengine] Re: Application instances seem to be too aggressively recycled
Heyo, On Tue, Mar 10, 2009 at 7:16 PM, cz czer...@gmail.com wrote: Actually, that is normal behavior. This has been discussed in previous threads. GAE seems to aggressively purge it's app cache, average app lifetime appears to be under 2 seconds. Appengine-patch may be marginally faster but both require Django1.x to be imported via zipimport, which is pretty expensive. Our app also exhibits this problem due to fairly low traffic, but there's not much that can be done as far as I can tell. Our app's dynamic pages contain lots of images also served via GAE, and since the browser can make many requests at once to load these, the app can be started up on several sever instances (probably due to load balancing) to deliver all the images. This can add up to a huge amount of CPU usage for just one page. Basically, the more traffic your app gets the faster it will be. Some people have suggested using a process somewhere to automatically make requests once per second or so to keep apps in the cache. But this is surely frowned upon by Google. Indeed, we are aware of this issue for some applications with certain load characteristics. We're taking steps to improve app caching to maximize instance lifetimes when it makes sense.

Heyo, Good finds, peterk! pubsubhubbub uses some of the same techniques that Jaiku uses for doing one-to-many fan-out of status message updates. The migration is underway as we speak (http://www.jaiku.com/blog/2009/03/11/upcoming-service-break/). I believe the code should be available very soon. 2009/3/11 peterk peter.ke...@gmail.com: The app is actually live here: http://pubsubhubbub.appspot.com/ http://pubsubhubbub-subscriber.appspot.com/ (pubsubhubbub-publisher isn't there, but it's trivial to upload your own.) This suggests it's working on appengine as it is now. Been looking through the source, and I'm not entirely clear on how the 'background workers' are actually working..there are two, one for pulling updates to feeds from publishers, and one for propogating updates to subscribers in batches. But like I say, I can't see how they're actually started and running constantly. There is a video here of a live demonstration: http://www.veodia.com/player.php?vid=fCNU1qQ1oSs The background workers seem to be behaving as desired there, but I'm not sure if they were just constantly polling some urls to keep the workers live for the purposes of that demo, or if they're actually running somehow constantly on their own.. I can't actually get the live app at the urls above to work, but not sure if it's because background workers aren't really working, or because i'm feeding it incorrect urls/configuration etc. Ah sorry yeah I still have the old version of the source running on pubsubhubbub.appspot.com; I need to update that with a more recent build. Sorry for the trouble! It's still not quite ready for widespread use, but it should be soon. The way pubsubhubbub does fan-out, there's no need to write an entity for each subscriber of a feed. Instead, each time it consumes a task from the work queue it will update the current iterator position in the query result of subscribers for a URL. Subsequent work requests will offset into the subscribers starting at the iterator position. This works well in this case because it's using urlfetch to actually notify subscribers, instead of writing to the Datastore. For other pub/sub-style systems where you want to write to the Datastore, the trick is to use list properties to track the subscribers you've published to. So for instance, instead of writing a single entity per subscriber, you write one entity with 1000-2000 subscriber IDs in a list. Then all queries for that list with an equals filter for the subscriber will show the entity. This lets you pack a lot of information into a single entity write, thus minimizing Datastore overhead, cost, etc. Does that make sense? @bFlood: Indeed, the async_apiproxy.py code is interesting.

The way you've phrased this implies that the web page has the word noner in it, which seems unlikely. Do you mean you aren't seeing the characters on the web page but instead some other characters are shown? In that case you should prob. check your encoding on the http level, in the html page that is returned and stuff like that. Also you should probably describe exactly what you did to change them to chinese characters on the off chance someone sees something incorrect in your process.

[google-appengine] Re: A question for Jaiku's developers, if they're watching..
I was just toying around with this idea yesterday Brett.. :D I did some profiling, and it would reduce the write cost per subscriber to about 24ms-40ms (depending on the number of subscribers you have..more = lower cost per avg), from 100-150ms. These are rough numbers with entities I was using, I have to do some more accurate profiling.. When I first thought about doing this, I was thinking :o I'll reduce write cost by a factor of hundreds!, but as it turns out, the extra index update time for an entity with a large number of list property entries eats into that saving significantly. But it still is a saving. Funnily enough the per subscriber saving increases (to a point) the more subscribers you have. I'm not sure if there's anything one can do to optimise index creation time with large lists.. I'm going to do some more work as well to see if there's an optimum 'batch size' for grouping subscribers together..at first blush, as mentioned above, it seems the larger the better (up to the per entity property/index cap of course).

[google-appengine] Re: jinja2 environment loading on each request to /
If you move Environment creation routine to another module it will be cached by Google, but only for few seconds (2-3?), so if your application does not get enough traffic you'd gain nothing from this. In my attempts to speedup things I discovered that only loader can be cached, but it has to be invalidated upon each new deployment so its key has to have application version added (this is how I did key versioning in my caching tools). Unfortunately, the gain from this caching approaches 0. And the last thing: Armin Ronacher, the guy behind Jinja, is aware of the problem and has some ideas on how to improve things on GAE, hopefully including template bytecode caching (this would be really super-nice!).

AttributeError: 'Document' object has no attribute '_key_name'
Error when I try to delete multiple documents from the datastore (same
entity group). This error only occurs when the delete request first
runs into a Transaction collision. So for example I send these three
delete requests in quick succession:
DELETE /v1/documents/1-62?version=0
DELETE /v1/documents/1-1071?version=0
DELETE /v1/documents/1-64?version=0
The first two requests work fine. But in this case the third dumps a
Transaction collision and then a no attribute '_key_name stack trace
in the logs, and the delete fails to take place:

The problem doesn't seem related to the documents server state. Right
after that above failure I sent the same delete request again, and it
worked fine that time. So I'm 99 percent sure that the cause is the
transaction collision, but I'm not sure how to resolve it. Quite
possibly I'm doing something wrong in my code, here's when my delete
method looks like. If you need to see more code I'd be happy to
provide the @require_document code to. Just let me know.
@require_document

version = self.request.get('version', None)
version = None if version == None else int(version)
if version == None:
self.error(400)
return
def txn():
if version != document.version:
raise ValueError, Version does not match
document version
deleted = Deleted(parent=document.parent_key(),

(document.key()))
document_account.documents_size -= document.edits_size
id_string = document.id_string()
account_emails = document.get_account_emails()
deleted.put()
document.delete()

clear_memcache(id_string, account_emails)
try:

if not api(self.request):

except ValueError:

except db.TransactionFailedError:

Thanks for your help.

[google-appengine] Re: A question for Jaiku's developers, if they're watching..
Unfortunately I do need to query them based on subscriber_id..so I can't pack them into a non-indexed property. Retrieving updates particular user has subscribed to is blazingly fast though...that's the gain in the end, I can query and fetch 1000 updates for a user sorted by date in 20-30ms-cpu. Love that :p In my hacky approaches previously where I tried to write once and then 'gather', I had to do lots of in-memory sorting and stuff, and even the results often wouldn't be totally accurate. I'm going to keep toying with the write end of things though..because in my full app, I may need to do write to other entities along with subscribers to do certain things I'm trying to achieve. So I'm going to be looking for every opportunity possible to optimise the cost of an 'update', which in my case may go beyond notifying subscribers. So any thoughts/ideas on further optimisation are more than welcome!! @Paul If you've more subscribers than will fit in one 'group' you'll need multiple groups, correct. So you'll have n writes, where n = number of subscribers/group-size, rounded up to the nearest whole number. Even with the costly index creation for each of these 'group' entities though, it should still work out a fair bit cheaper than writing a seperate entity for each subscriber. On Mar 13, 11:47 am, bFlood bflood...@gmail.com wrote: @peterk - if you don't need to query by the subscriber, you could alternatively pack the list of subscribers for a feed into a TextProperty so it is not indexed. I use TextProperty a lot to store large lists of geometry data and they work out pretty well @brett - async! looking forward to it in future GAE builds. thanks cheers brian On Mar 13, 5:37 am, peterk peter.ke...@gmail.com wrote: I was just toying around with this idea yesterday Brett.. :D I did some profiling, and it would reduce the write cost per subscriber to about 24ms-40ms (depending on the number of subscribers you have..more = lower cost per avg), from 100-150ms. These are rough numbers with entities I was using, I have to do some more accurate profiling.. When I first thought about doing this, I was thinking :o I'll reduce write cost by a factor of hundreds!, but as it turns out, the extra index update time for an entity with a large number of list property entries eats into that saving significantly. But it still is a saving. Funnily enough the per subscriber saving increases (to a point) the more subscribers you have. I'm not sure if there's anything one can do to optimise index creation time with large lists.. I'm going to do some more work as well to see if there's an optimum 'batch size' for grouping subscribers together..at first blush, as mentioned above, it seems the larger the better (up to the per entity property/index cap of course). Thanks also for the insight on pubsubhubub..I eagerly await updates on that front :) Thank you!! On Mar 13, 8:05 am, Paul Kinlan paul.kin...@gmail.com wrote: Just Curious, For other pub/sub-style systems where you want to write to the Datastore, the trick is to use list properties to track the subscribers you've published to. So for instance, instead of writing a single entity per subscriber, you write one entity with 1000-2000 subscriber IDs in a list. Then all queries for that list with an equals filter for the subscriber will show the entity. This lets you pack a lot of information into a single entity write, thus minimizing Datastore overhead, cost, etc. Does that make sense? So if you have over the 5000 limit in the subscribers would you write the entity twice? Each with differnt subscriber id's? Paul 2009/3/13 Brett Slatkin brett-appeng...@google.com Heyo, Good finds, peterk! pubsubhubbub uses some of the same techniques that Jaiku uses for doing one-to-many fan-out of status message updates. The migration is underway as we speak (http://www.jaiku.com/blog/2009/03/11/upcoming-service-break/). I believe the code should be available very soon. 2009/3/11 peterk peter.ke...@gmail.com: The app is actually live here: http://pubsubhubbub.appspot.com/ http://pubsubhubbub-subscriber.appspot.com/ (pubsubhubbub-publisher isn't there, but it's trivial to upload your own.) This suggests it's working on appengine as it is now. Been looking through the source, and I'm not entirely clear on how the 'background workers' are actually working..there are two, one for pulling updates to feeds from publishers, and one for propogating updates to subscribers in batches. But like I say, I can't see how they're actually started and running constantly. There is a video here of a live demonstration: http://www.veodia.com/player.php?vid=fCNU1qQ1oSs The background workers seem to be behaving as desired there, but I'm not sure if they were just constantly polling some urls to keep

if your app handlers are cached (ie via if __name__ == '__main__':main
()) this should be imported only once per server instance. It also
caches templates both in memcache (for 8 minutes) and in instance
memory
(in case of local testing, templates are not cached in memory, so you
can make changes and see the changes immediately)

If you move Environment creation routine to another module it will be
cached by Google, but only for few seconds (2-3?), so if your
application does not get enough traffic you'd gain nothing from this.
In my attempts to speedup things I discovered that only loader can be
cached, but it has to be invalidated upon each new deployment so its
key has to have application version added (this is how I did key
versioning in my caching tools). Unfortunately, the gain from this
caching approaches 0.
And the last thing: Armin Ronacher, the guy behind Jinja, is aware of
the problem and has some ideas on how to improve things on GAE,
hopefully including template bytecode caching (this would be really
super-nice!).

anything im missing here ? I think this could be adding also an extra

Hi,
I'm new to Google Appengine and Python programming and I've been
having a problem that's just plain driving me nuts!
I want to implement a RESTful style API, such that when I enter:
http://url/trend/trendname
A page loads and displays information about the trend.
I've already successfully implemented Open Flash Chart 2 and SWFObject
for a basic root URL.
e.g. http://url/somepage?parameter=xyz
Some of the logic is inside Django templates, but the end result of
the relevant code outputed is this.
script type=text/javascript src=js/swfobject.js/script
script type=text/javascript
swfobject.embedSWF(
OFC.swf, graph,
450, 450, 9.0.0, expressInstall.swf,
{ data-file: api/graph/LISTALLTIME });
/script
So far so good. The relevant bit here is the OFC.swf reference
which is the Open Flash Chart 2 SWF object we are executing.
The problem comes when I move to a dynamic URL.
Here's some of my APP.YAML and the WSGIApplication call.
handlers:
- url: /OFC.swf
static_files: flash/OFC.swf
upload: flash/OFC.swf
- url: /.*
script: twendly.py
application = webapp.WSGIApplication(
[('/', MainPage),
(r'/trend/(.*)', GraphTrend),
(r'/api/graph/(.*)/(.*)',
GraphTrendValues),
(r'/api/graph/(.*)',
GraphValues),
], debug = True)
So when I call http://appname/trend/trendname everything seems to
work as it should and I end up with this in my HTML
script type=text/javascript src=js/swfobject.js/script
script type=text/javascript
swfobject.embedSWF(
/OFC.swf, graph,
450, 450, 9.0.0, expressInstall.swf,
{ data-file: api/graph/LIST1HR/watchmen });
/script
Looks good BUT it it's not locating the OFC.swf file successfully.
This has bugged me for days and tonight I figured I get rid of the
trend directory and do it as a top level URI e.g. change my
WSGI.Application call to this instead:
application = webapp.WSGIApplication(
[('/', MainPage),
(r'/(.*)', GraphTrend),
NOTE CHANGE ON THIS LINE
(r'/api/graph/(.*)/(.*)',
GraphTrendValues),
(r'/api/graph/(.*)',
GraphValues),
], debug = True)
And call http://appname/trendname
Everything works! Graph loads etc. - this all makes me think it's got
something to do with relative URL paths, but I would of expected /
OFC.SWF to load it from the root where the APP.YAML is redirecting.
For reasons of elegance (and not getting stumped) I really want to
implement it with the trend key word as part of the URI, but this
seems to be a no go at the moment.
I'm guessing I need a different configuration for my APP.YAML, but I'm
really stuck.
Can anyone help me out?
Thanks!
Tim

[google-appengine] Re: Transaction collision AND AttributeError: 'Document' object has no attribute '_key_name'
After a bit more playing and reading I think the route of my problem is that I've designed things so that there is a bit to much contention in my entity group, I probably shouldn't be running into failed transactions so much in the first place. My basic design is that each user account marks the root of an entity group. And the users documents are children of that group. This seems like a reasonable design to me, but the problem is that my sync client hits the group pretty hard. If the user deletes all their documents locally, then the sync client fires of a separate DELETE request for each document, all at the same time, and I think that's the root of the problem. So I guess I need to write a batch delete handler... or make the client send the DELETE requests in sequence, instead of all at once. Let me know if I'm missing a better way... still getting used to web programming.

[google-appengine] Re: UpLoading Problem
This is a pain. After running on GAE for months I had this problem yesterday. Lots of potential problems. First, make sure you have created a GAE account. Then make sure you know what the application name is on GAE. Then make sure the name of your application in the app.yaml file is equal to the name of the application on the host. You have most likely done all this, I know I did. My problem was cookies stored on my local machine. I have two gmail accounts because I am experimenting with sending emails from my application. I login to google using both gmail accounts which create cookies on my local machine. Appcfg.py does not like this. To make a long story short, on your desktop delete the .appcfg_cookies and .appcfg_nag files. On XP these are in, C:\Documents and Settings\%user%\then try again. Not sure this will solve your problem it did mine. Also if you try too many times (do not know how big too many is), appcfg.py creates a file in your application directory on your development machine that locks you from uploading no matter what. Appcfg.py simply stops running. Look for strange *.py files in your application directory and delete the files.

[google-appengine] best transaction and then memcache.delete pattern
What's the best pattern for using transactions together with memcache.delete? def txn(): ... get, put some entities Option 1: do memcache.delete here db.run_in_transaction(txn) Option 2: do memcache.delete here Option 1 is to run do it in the last line(s) of the txn() function. Option 2 is to do it right after the successful call to run_in_transaction(). Option 2 feels a bit more correct, but Option 1 is convenient because I have easy access to the various model properties there. Are both options OK, or do that have different behavior that could cause problems?

[google-appengine] Re: Data Storage Size - multiplier per object
Hi, There is no 'multiplier' per se on datastore storage. The issue is that we account for both the size of the data stored and the space taken by the indices for this data. As such, the amount of storage you use depends specifically on the types of indexes your application has. We are working on getting better documentation together that will give you a good idea on how you can account for the amount of storage an entity will take. Please note that the FAQ on this subject currently is _not_ correct and we will be updating it. -Marzia On Tue, Mar 10, 2009 at 9:28 AM, Jonathan Ultis jonathan.ul...@gmail.comwrote: I created a model with fixed content that requires ~250b serialized, including all field names, the key, and the kind name, and parent (None). I added 312000 of those to the datastore, for 75 megs of raw data. There are 8 indexable fields, The indices should require no more than 176 megs of additional space, if the indices don't do any sort of column compression. That's 250 megs of raw space. But, the data store reports 1GB of space used. That suggests perhaps 2x redundancy, plus a 50% fill rate in big table. Or, maybe just 4x redundancy. No idea. Anyhow, for now, take your raw object size including kind, key, field names, and field content, and multiply by 10x-15x, depending on how many indexable properties you have, to get your final storage size. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] app-engine-patch MediaGenerator not generating any media!
Can anyone help please?
I have been playing around with the app-engine-patch sample app and
guestbook tutorial - great starter resource. Everything has gone very
smoothly until I tried to create some stylesheets for my base
template.
I followed the instructions from the MediaGenerator page in the
documentation and added 'styles.css' to myapp/media and /media. I also
added this code to my /settings.py;
# Combine media files
COMBINE_MEDIA = {
# Create a combined JS file which is called combined-en.js for
English,
# combined-de.js for German, and so on
'combined-%(LANGUAGE_CODE)s.js': (
# Integrate bla.js from myapp/media folder
# You don't write media because that folder is used
automatically
'myapp/bla.js',
# Integrate morecode.js from media under project root folder
'global/morecode.js',
),
# Create a combined CSS file which is called combined-ltr.css
for
# left-to-right text direction
'combined-%(LANGUAGE_DIR)s.css': (
'myapp/style.css',
# Load layout for the correct text direction
'global/layout-%(LANGUAGE_DIR)s.css',
),
}
I now get following line in my generated html page;
link rel=stylesheet type=text/css href=/generated_media/media/1/
combined-ltr.css /
but no 'combined-ltr.css' has actually been generated!? - should it
have been?
Any input most appreciated. Cheers
P.S. I am very new to python and django so apologies if I have made a
silly mistake

[google-appengine] Re: 1 Select = 6 Datastore API calls?
Hi,
It depends on how you are retrieving the results. If you use fetch() it
should be a single query in the datastore. However, if you iterate over the
query, it does batch the calls in groups of 20.

I have an object that will be stored with a user-provided key_name.
Everything works fine, until there is an apostrophe (') in the name.
In the SDK, I can store an object in the datastore and retrieve it
using get_by_key_name() even if it has an apostrophe.
In production, I can only store the object (It's visible in the admin
data viewer), but cannot retrieve it using get_by_key_name() if the
key_name contains an apostrophe.
Why is this?
Thank you!
P.S. I want the users to be able to enter an apostrophe since I am
storing lists. And they most likely will name it as albert's list,
raphael's list, etc...

Hi,
I'm new to Google Appengine and Python programming and I've been
having a problem that's just plain driving me nuts!
I want to implement a RESTful style API, such that when I enter:
http://url/trend/trendname
A page loads and displays information about the trend.
I've already successfully implemented Open Flash Chart 2 and SWFObject
for a basic root URL.
e.g. http://url/somepage?parameter=xyz
Some of the logic is inside Django templates, but the end result of
the relevant code outputed is this.
script type=text/javascript src=js/swfobject.js/script
script type=text/javascript
swfobject.embedSWF(
OFC.swf, graph,
450, 450, 9.0.0, expressInstall.swf,
{ data-file: api/graph/LISTALLTIME });
/script
So far so good. The relevant bit here is the OFC.swf reference
which is the Open Flash Chart 2 SWF object we are executing.
The problem comes when I move to a dynamic URL.
Here's some of my APP.YAML and the WSGIApplication call.
handlers:
- url: /OFC.swf
static_files: flash/OFC.swf
upload: flash/OFC.swf
- url: /.*
script: twendly.py
application = webapp.WSGIApplication(
[('/', MainPage),
(r'/trend/(.*)', GraphTrend),
(r'/api/graph/(.*)/(.*)',
GraphTrendValues),
(r'/api/graph/(.*)',
GraphValues),
], debug = True)
So when I call http://appname/trend/trendname everything seems to
work as it should and I end up with this in my HTML
script type=text/javascript src=js/swfobject.js/script
script type=text/javascript
swfobject.embedSWF(
/OFC.swf, graph,
450, 450, 9.0.0, expressInstall.swf,
{ data-file: api/graph/LIST1HR/watchmen });
/script
Looks good BUT it it's not locating the OFC.swf file successfully.
This has bugged me for days and tonight I figured I get rid of the
trend directory and do it as a top level URI e.g. change my
WSGI.Application call to this instead:
application = webapp.WSGIApplication(
[('/', MainPage),
(r'/(.*)', GraphTrend),
NOTE CHANGE ON THIS LINE
(r'/api/graph/(.*)/(.*)',
GraphTrendValues),
(r'/api/graph/(.*)',
GraphValues),
], debug = True)
And call http://appname/trendname
Everything works! Graph loads etc. - this all makes me think it's got
something to do with relative URL paths, but I would of expected /
OFC.SWF to load it from the root where the APP.YAML is redirecting.
For reasons of elegance (and not getting stumped) I really want to
implement it with the trend key word as part of the URI, but this
seems to be a no go at the moment.
I'm guessing I need a different configuration for my APP.YAML, but I'm
really stuck.
Can anyone help me out?
Thanks!

[google-appengine] Datastore usage goes up over time?
I imported about 3 million very simple records into appengine, using the bulk_uploader tool. The raw size of the input CSV was 85M. After upload, google showed my datastore quota usage as being about 0.16G -- a factor of 2 increase, but reasonable. I left the application for a few days, and logged back in to check on it: suddenly my datastore usage is pegged at 100% (1.0G)! First: why did my datastore usage grow over time? My application isn't writing records to the datastore, just serving queries against the static data set. Is it because Google created indexes? Can I stop that from happening? Second: how do I find out how much space my data is really taking up (according to the quota system). I'm reluctant to turn on billing until I know whether the suddenly-bloated version of my data is 1.01G or 16G -- and until I know whether it will continue to bloat further! http://cscott-geotest.appspot.com/ is the application URL; as you can see, it's a very simple application which returns a guessed zip code and country for the user based on the IP address their request comes from. The model looks like: class IP2PostalCode(BaseModel): Starting IPv4 address, as a 32-bit integer; ie, a.b.c.d is represented as 256*(256*(256*a+b)+c)+d ipStart = db.IntegerProperty(required=True) ISO-3166 alpha2 country code for this IPv4 address block. country = db.StringProperty() State (AdminCode1) for this block. state = db.StringProperty() City for this block. city = db.StringProperty() Postal code for this IPv4 address block. postcode = db.StringProperty() Can someone help me figure out what's going on here? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: DownloadError: ApplicationError: 5 Using GData Provisioning API
Thanks for your response Scott,
I guess it happens the same with all GData API's. It's kind of ironic,
given that they are running in the same Google data centers. I'll be
watching any progress on this.

David,
I'm receiving the same error and similar results albeit with a
different API. This happens when I try to create a new empty (not
uploaded) spreadsheet. The spreadsheet shows up, but I still get
ApplicationError:5. Until I can find the solution, I've chosen to just
catch the exception and work around it. On my dev engine I receive a
slightly different exception, ApplicationError:2 timeout. This happens
on the request to google. Again, in dev even though I get the error
the spreadsheet is created. The details of the request are listed
below. The request looks to be in line with the API sample code
athttp://groups.google.com/group/Google-Docs-Data-APIs/browse_frm/threa...
and http://code.google.com/apis/documents/docs/2.0/developers_guide_proto
I'll keep looking and will let you know if I find anything out.

[google-appengine] Re: SWFObject, dynamic URIs and flash.
Tim,
In your app.yal you wrote:
- url: /OFC.swf
static_files: flash/OFC.swf
upload: flash/OFC.swf
replace this with the followoing if you want to serve OFC.swf from /
- url: /OFC.swf
static_files: /OFC.swf
upload: /OFC.swf
If you are planning to add other static files, and unless you have to
put them in /, its better to declare static_dir and put this kind of
files there. Adding static_files is ok for files like sitemap or
robot.txt, but to avoid adding new lines for every new .swf added, it
better to keep them under static dir.
Cheers,
Sargis

Hi,
I'm new to Google Appengine and Python programming and I've been
having a problem that's just plain driving me nuts!
I want to implement a RESTful style API, such that when I enter:
http://url/trend/trendname
A page loads and displays information about the trend.
I've already successfully implemented Open Flash Chart 2 and SWFObject
for a basic root URL.
e.g. http://url/somepage?parameter=xyz
Some of the logic is inside Django templates, but the end result of
the relevant code outputed is this.
script type=text/javascript src=js/swfobject.js/script
script type=text/javascript
swfobject.embedSWF(
OFC.swf, graph,
450, 450, 9.0.0, expressInstall.swf,
{ data-file: api/graph/LISTALLTIME });
/script
So far so good. The relevant bit here is the OFC.swf reference
which is the Open Flash Chart 2 SWF object we are executing.
The problem comes when I move to a dynamic URL.
Here's some of my APP.YAML and the WSGIApplication call.
handlers:
- url: /OFC.swf
static_files: flash/OFC.swf
upload: flash/OFC.swf
- url: /.*
script: twendly.py
application = webapp.WSGIApplication(
[('/', MainPage),
(r'/trend/(.*)', GraphTrend),
(r'/api/graph/(.*)/(.*)',
GraphTrendValues),
(r'/api/graph/(.*)',
GraphValues),
], debug = True)
So when I call http://appname/trend/trendname everything seems to
work as it should and I end up with this in my HTML
script type=text/javascript src=js/swfobject.js/script
script type=text/javascript
swfobject.embedSWF(
/OFC.swf, graph,
450, 450, 9.0.0, expressInstall.swf,
{ data-file: api/graph/LIST1HR/watchmen });
/script
Looks good BUT it it's not locating the OFC.swf file successfully.
This has bugged me for days and tonight I figured I get rid of the
trend directory and do it as a top level URI e.g. change my
WSGI.Application call to this instead:
application = webapp.WSGIApplication(
[('/', MainPage),
(r'/(.*)', GraphTrend),
NOTE CHANGE ON THIS LINE
(r'/api/graph/(.*)/(.*)',
GraphTrendValues),
(r'/api/graph/(.*)',
GraphValues),
], debug = True)
And call http://appname/trendname
Everything works! Graph loads etc. - this all makes me think it's got
something to do with relative URL paths, but I would of expected /
OFC.SWF to load it from the root where the APP.YAML is redirecting.
For reasons of elegance (and not getting stumped) I really want to
implement it with the trend key word as part of the URI, but this
seems to be a no go at the moment.
I'm guessing I need a different configuration for my APP.YAML, but I'm
really stuck.
Can anyone help me out?
Thanks!

Hmmm. My next app engine project _was_ going to be an app that relied on twitter. This doesn't sound good. As per your situation the app wouldn't hammer twitter, one request to the search API every 5-10 minutes or so. Given its not exactly an app engine problem did you try contacting twitter to see if they could build more 'smarts' into their rate limiting?

[google-appengine] Re: Twitter - rate limit exceeded
Hmmm yes this is a difficult one. Neither Twitter nor Google are being unreasonable, and each GAE developer is probably performing a sane number of Twitter API requests but combined we are ruining it for everyone. Ohhh the solution? I can't think of a good solution Twitter could implement which wouldn't make it easy to circumvent their limit unreasonably. I do happen to have a hosted linux server a I can put a proxy script on, I guess I'm lucky there, but I am using GAE for its scaleability which my server certainly isn't. I don't need to go into all the reasons GAE is more scaleable than my own server :-) If anyone thinks of anything, I'd love to know. Rich 2009/3/14 lock lachlan.hu...@gmail.com Hmmm.
