[google-appengine] Reserved URLs clarification

[Alexander Konovalenko]

The documentation [1] says the following URL paths are reserved:

  /_ah/
  /form

[1] 
http://code.google.com/appengine/docs/python/config/appconfig.html#Reserved_URLs

Now, it is clear from the actual use of the /_ah/ prefix that anything
that starts with /_ah/ is reserved. As for /form, there is room for
ambiguity here. Suppose an app is deployed on the www.example.com
Google Apps domain. Which of the following URLs are reserved?

(1) www.example.com/form
(2) www.example.com/form?var=value
(3) www.example.com/form/
(4) www.example.com/form/?var=value
(5) www.example.com/form/foo
(6) www.example.com/forms/bar
(7) www.example.com/formula

It looks like only (1) and (2) are reserved. If so, please update the
docs to make this distinction clear: any URL that *starts* with /_ah/
is reserved but only /form itself is reserved, and it is safe to use
any other URLs that start with /form.

By the way, why was /form reserved in the first place? It is a useful
URL and it would be nice to lift that limitation and move anything
that could possibly use it under /_ah/form. Reserving such a common
word is inelegant. In practice, migrating an existing app to App
Engine if the app has some important page at /form is impossible
because of that limitation. The original appname.com/form page could
be bookmarked or linked to from numerous places, and we can't even set
up a redirect to work around the problem.

Thanks.

Alexander

Hi Alexander

I think google are saying they are reserved as guide so you don't clash with 
some service of theirs, however I don't actually see 
any way of preventing you from using any of these paths in urls if you 
handling them yourself.

In my case I don't use webapp and don't only map a few of the _ah paths, and 
so my default handler gets all forms of /form as well as /_ah/* that don't 
match existing mapped handlers in app.yaml.

The danger is you prevent the access of some useful appengine service.

Tim,

Thanks for your reponse.

Yes, for some /_ah/ paths, you're even supposed to handle them
yourself. For example, the Python warmup handler.

But I couldn't get my code to handle /form (not /form/ or
/form/something, but /form itself). Google's built-in handler always
takes precedence and returns a Google-branded 404 page with a nice
robot image. So the issue with /form is not theoretical.

What do you use /form for?

Regards,
Alexander

[google-appengine] Re: Reserved URLs clarification

[Tim Hoffman]

HI

Your right, I missed that specific case /form

Interesting, google are trapping that specific case before it even
gets to your instance.

It does seem somewhat arbitrary to intercept /form  but /form/ gets
through
I am not sure those two are really different.  (In fact I generally
allow both paths to resolve to the same
entity through traversal.  )

I actually don't use /form for anything, all of my urls asentity
traversal oriented which means the url
generally starts with a an entity.  (though in a cms you could call
any top level container or entity anything you want,
which could effectively hide a path, if a user accidentally called
something "form")

I did test but actually I realize now I typed /form/ not /form so I
missed the specific issue you raised, sorry.

Probably worth an new issue, asking for accurate documentation of the
url root paths that will not be passed through to
appengine apps.

Re: [google-appengine] Re: New Pricing ROCKS! for Small apps

[Niklas Rosencrantz]

Thanks for sharing the info about your apps. I think it could be better for 
apps that are medium-sized. If your app is commercial you can't expect to 
host it for free anyhow. And I agree that you shouldn't have to pay for 
tests or something that is nothing but development and research. Attached is 
my latest pricing - it's still not much to talk about and effects may have 
come from running mapreduce since I'm migrating to HRD.

Niklas

I opened http://code.google.com/p/googleappengine/issues/detail?id=5915 in
case anyone wants to star. Looking forward to the attention of the GAE team.


In the meantime, it would be cool if there were a reference app
demonstrating various usage of the edge cache. I'm picturing something like
this (in flask speak):

@app.after_request
def make_conditional(response):
"""
Unconditional request handled by Python::

$ curl -I foo.appspot.com
HTTP/1.1 200 OK
Cache-Control: public, max-age=
ETag: "foo"
...

You should see "in Python" logged for this request.

Subsequent conditional request should be handled by Google's edge
cache::

$ curl -H'if-none-match: "foo"' -I foo.appspot.com
HTTP/1.1 304 Not Modified
...

"in Python" won't be logged for this request if handled by the edge
cache.

"""
app.logger.debug('in Python')
response.cache_control.public = True
response.cache_control.max_age = 
# in case Google's edge cache isn't working, serve 304s from Python:
response.add_etag()
return response.make_conditional(request)



I'm seeing "in Python" logged for both requests when I try something like
this. If anyone has any working examples, please share them.

[google-appengine] How can I wrap/use blobstore API to support file upload with just one http request

[ofridler]

Hi
I'm using GAE (Java) as the backend server for iPhone app, and using
blobstore for storing photos & videos uploaded from iPhone.

Is there a way to simplify the API for the iPhone client so for each
file upload only one http request will be needed?

Today we're using 2 steps flow, the first http request is calling
blobstoreService.createUploadUrl and creating the URL that is used in
the second http request that is uploading the file, this flow is more
complex and has much more corner cases that the usual one http upload
call.

Thanks
Oren.

That's an interesting point. If you could optimize your resource usage to

[google-appengine] Re: /_ah/login returns status 500

[Gabriel Charette]

Interesting,

I am trying to setup authentication using /_ah/login as well and am
seeing 500s repetitively (actually that's all I'm seeing).
I can swear I've had it working before exactly the way I'm
implementing it right now, but for 2 days I've been banging my head
trying to figure out why it doesn't work.

Maybe after all this is a real issue, not a problem in my new
implementation??

Is anyone able to get a response from /_ah/login right now??

Thanks,
Gabriel

[google-appengine] How-to create a custom admin page in Google App Engine

[olivier hubert]

Hello,

Can you provide a simple exemple to create a custom admin page ?
In the documentation I found the process to create a new entry in the
admin section.

admin_console:
  pages:
  - name: test
url: /admin/test

But I don't have a sample page.
In the documentation, the new entry in the admin console is a iframe.
So the "test" page is only html or is a python script with a rendering
in the iframe ?

Another question, with the SDK a custom admin page can be rendering ?

Thanks

Olivier

Hi,

I had the same problem and just found the solution.

My token was no longer valid, which means your app has to invalidate
the token in the cache itself and redo the request with the new token.

[google-appengine] Apps For Domains is a MAJOR failing of AppEngine

[Brandon Wirtz]

This is more of a rant, than anything that you will likely encounter..

 

I use the Adwords API for a lot of things, mainly advising clients that
spend north of a half million dollars a month with adwords. (I only get a
licensing fee on the app sorry).

 

Recently, because Google changed its policies on unified logins, when I
logged in to Google Voice it made me migrate my account. After the migration
some of my Google Unified Logins weren't Migrated. Adwords being a primary
example. And My Apps For Domains became disassociated with the Account.

 

You can't call apps for domains without a pin. If you do get someone on the
phone using the pin from your other account they tell you they can't help
you because that account isn't associated with your login. When you call
adwords they tell you that your account has to get support from apps for
domains.  

 

As a Result I've had a week plus of downtime on my Adwords App, because of
Apps For Domains.  I could move the App to use a different API-key on
another account, but because of the way the outsourced company I used
developed the app I'd have to manually update credentials in every install.


 

Awesome sauce I know.  But the over Arching Theme is that Adwords support
while unhelpful have been friendly, though they will only move my issue
forward at the rate of 1 email a day, and are trying to support another
groups mess. The 6 plus people I have talked to in Apps for Domains support,
have been rude enough that they actually hung up on me, put me on hold for
2+ hours, and told me "I was beyond help".  I realize that for $10 you can't
afford to support me, but for the amount I spend elsewhere, be nice.

 

This experience with AppsForDomains has soured me towards recommending GAE
more than the change in pricing.  More than the Drama of moving from MS to
HR. More than the "you can't migrate off it".   If I have a week of downtime
because tech support won't even talk to me.  That's a Far larger concern

[google-appengine] Multiple attachments limits

[thstart]

According to Mail
Quotas and Limits

http://code.google.com/appengine/docs/python/mail/overview.html
maximum size of outgoing mail messages, including attachments10 megabytes
The question I have is if I have multiple attachments what is the limit? 
For example I want to send 5 attachments 10MB each. Can I do that?
If not how is the best practice to implement this functionality?

Also are there a change in new pricing related to email attachments?

Thanks in advance,

[google-appengine] Property type is NULL?

[mac]

I think I need to change the title. When I mentioned the NULL in the last 
thread. I mean the Property type is NULL, not the content of that property 
is NULL. That's quite odd to me.

[google-appengine] Worst-case scenario for eventual consistency in the HRD?

[Jeff Schnitzer]

I know that an index update in the HRD will typically be visible
within a couple seconds.  That's the average case.  What is the
worst-case?

Assuming something in the datacenter goes wacky, how long might it
take for an index to update?  Tens of seconds, minutes, hours, days?

Thanks,
Jeff

Re: [google-appengine] Apps For Domains is a MAJOR failing of AppEngine

[Jeff Schnitzer]

I'd like to give a huge +1 to this.  The Google Apps system is a trainwreck.
 I made the terrible mistake of moving some of my personal domains to Google
Apps and now:

 * I'm in some sort of Catch-22 that locks me out of my adwords account.
 Not a big deal (it wasn't important) but I can't create a new adwords
account (seriously, not even by creating new Google Accounts) and I can't
delete the old one.  I like to think I'm a smart guy, but this is worse than
one of those chinese puzzles because I'm not 100% certain there is a
solution.  Support?  Nonexistant.

 * The huge delays on moving domains around in Google Apps is lunacy.  Let's
say you're running a GAE app on a doman configured as a domain alias for
Google Apps Domain A and you want to split it out into its own Google Apps
Domain (ie, you sold the product).  Impossible without a week's downtime
while the domain releases from A.  WTF?

 * Don't get me started on the big problems I've had with logins working
some places and not others (eg, Google Groups).

Maybe this isn't quite the place for my rant, but since GAE depends on
Google Apps, it would be nice if Google Apps had the kind of support that we
expect from GAE.

Well it is the right place to rant in so far as we do depend on Apps for

I completely agree. I love most things Google, but moving to Google
Apps has been less than a smart idea.

User authentication is a complete and utter nightmare. For the longest
time I could not use Google Groups with my apps user name... I know,
it does not make sense. I still don't understand what the heck is
going on with YouTube. I've just given up trying to understand the
logic behind disallowing access to Google Apps users or how it even
works. Why can't we just login?

And Apps users are blocked from new Google features such as Google+...
not a good way to introduce new products to the people who were
confident enough to buy into Google Apps.

Just make it work :-)

Re: [google-appengine] Worst-case scenario for eventual consistency in the HRD?

[Ikai Lan (Google)]

I'll check for you, but FWIW here are the last numbers for master/slave I
heard with regards to replication delay:

- most of the time data is replicated within hundreds of milliseconds
- when there is something wrong, mean time is 3 minutes, with an upper bound
that is roughly 10 minutes

If a data center goes offline, that's the window of writes you may lose on
master/slave. On HRD you don't lose data.

I'll double check with the datastore team to see if we have numbers, but it
might not work the same way. When you do a write, a majority of datastore
instances have to acknowledge receiving the write and having appended it to
the write journal. Thus, if the primary datastore goes offline, application
servers make RPCs to the other datastores and use the first response that
comes back. The datastores that are running behind still try to catch up in
the background and continue to apply writes from the journal. I suppose the
number you're looking for here is: what is replication delay if a datastore
isn't forced to catch up?

[google-appengine] gaeutilities sessions, plz to help a n00b

[Emlyn]

I'm trying the gaeutilities session library for some new apps I'm building.

http://gaeutilities.appspot.com/session

I'm using it for two things:

- basic, old school session stuff (ie: a dictionary persistent across
user visits)

- securing ajax callbacks (the session contains the indication of
whether the user is logged in; session library's cookie goes from
server to client, back through ajax call through rest interface to
server, session is reconsituted based on it, if it's not the same one
then there's no login indication, call fails)

The library is pretty cool, a bit magical actually. I'm reading the
code to try to understand the magic, and think I'm getting a handle on
it.

However, in the doc, there is this:

"In order to take advantage of the token system for an authentication
system, you will want to tie sessions to accounts, and make sure only
one session is valid for an account. You can do this by setting a
db.ReferenceProperty(_AppEngineUtilities_Session) attribute on your
user Model, and use the get_ds_entity() method on a valid session to
populate it on login."

Why would I want to do this? I'm happy for two separate logins by the
same person to have different sessions, and I'm happy for subsequent
visits to begin with an empty session dictionary each time. Am I
missing something here?

[google-appengine] Re: SmartGwt treefrog skin

[Paulo Bomfim]

Hi Brandon,
It just doesn't seem right, since it has a schema of multiple
folders... the huge number of images comes from the SmartGWT skin.
I went to GDD 2011 in São Paulo last friday and got to speak to
+Wesley Chun. He said I should send a report about it on App Engine
site, explaining this situation.
I'll give it a try!
Thanks man!

gaeutilities sounds nice, but in practice it is real slow. Use

[google-appengine] Random aborted requests?

[fredrossperry]

Our app consists of some GAE services and a Flash client.  Starting
last Thursday
(as best we can tell), some folks started to get random aborted
requests.  These are either
static GETs or POSTS, made by the Flash client, to GAE services that
we've written.

We can see the requests being made using Firebug, but they are never
logged by GAE.
A long time (20-30 secs) goes by before the request is aborted.  We
can make the identical
request right away and it will succeed.

We've not changed client code or server code between the time things
were working well,
and now.

This is happening for folks using Firefox for Mac in three different
geographical locations.
We do get better behavior using Safari, BTW.

Anyone seen any, or more, aborts like this in recent days?

[google-appengine] Re: How do you view data downloaded from your app?

[Tim Hoffman]

Probably the easiest thing to do , is upload your data to the local dev 
server,
Then you can run your app, or play with the data directly with the remote 
api
