[google-appengine] Re: Support for Firestore Client on App Engine Standard?

2018-08-15 Thread Joel Fernandes

Our application is built on top of Firebase and its services, including 
Firestore. Although Cloud Datastore provides identical functionalities, I'm 
not if it can be or should be integrated with Firebase, when Firestore is 
an option that is readily available. 

However, it seems like the SDK libraries are supported 

 
by the Python 3.7 runtime on GAE standard. That's something I need to test 
now.

[google-appengine] Support for Firestore Client on App Engine Standard?

2018-08-14 Thread Joel Fernandes



This is with regard to #179 
 on Firebase 
Admin Python SDK.


Is there a workaround, or any updates on the timeline on when support for 
Firestore client will be added on App Engine Standard?

[google-appengine] App engine app stopped functioning

2017-10-26 Thread Roku Joel

my app which was a simple oauth handler for three applications ceased 
functioning for some reason. My email had some things about needing to 
migrate to python 2.7.9 but actually it was developed with 2.7.10 - which 
as far as I can tell is a newer version - on my other laptop I have 2.7.14. 
Regardless, the app stopped working. I saw something about datastore_admin 
being deprecated and how to turn it back on, so I did that, redeployed the 
app using the 2.7.14 and it is still not working. 

The app is access by going to 
http://appname.appspot.com/getRegCode?deviceID==_token===imageservice.
 

What i'm getting looks like:
The requested 
URL/getRegCode?deviceID==_token===imageservice

was not found on this server. 

Any ideas?

[google-appengine] Avoiding races when using memcache to back datastore queries

2016-03-19 Thread Joel Holveck

I'm working on a bit of an app that can receive requests for the same query
several times in rapid succession, and it's almost always the same in a
short timespan. Rather than doing datastore queries each time, I'd like to
cache the information in memcache.

I first thought I'd model my mechanism on how ndb uses memcache. If I'm
reading the docs right
at https://cloud.google.com/appengine/docs/python/ndb/cache#memcache , ndb
will delete a memcache key prior to a .put() and expect the first .get() to
populate the memcache. But it sounds like this could cause a race if
instance 1 is performing a put at the same time as instance 2 is performing
a put, and that the stale data could be cached.

1. Instance 1 determines it needs to put changes to an object into the
datastore.
2. Instance 2 determines it needs to get the same object from datastore.
3. Instance 1 deletes the memcache key.
4. Instance 2 queries the memcache, and finds it empty.
5. Instance 2 loads the old version from the datastore.
6. Instance 1 puts the new version in the datastore.
7. Instance 2 puts the old version's data into memcache.
8. Much later, Instance 3 queries the memstore for the object, and gets
the old version.

In this case, this is only using methods that are supposed to have strong
consistency guarantees, but the way they're composed means that ndb's
"fetch by key" would not be strongly consistent.

I suspect the docs are simplifying the actual consistency protocol used by
ndb, but this seems like a problem that needs to be solved pretty
frequently. Anybody have insights to share?

As I mentioned, my ultimate goal is to build a mechanism to cache a
particular query in memcache, but I'm looking at just a get_by_id
operation's caching to get ideas of how to do this well.

Thanks,
Piquan

[google-appengine] Re: Avoiding races when using memcache to back datastore queries

2016-03-18 Thread Joel Holveck

Thanks for the help!

It looks like if memcache evicts the _LOCKED sentinel between steps 3 and 4
of Greg's sequence (for example, resets the shard in a maintenance or
migration event), this algorithm could still cache stale data. Greg, you
mentioned that it uses CAS to prevent problems with memcache failures; I'm
trying to think about how the instance could prevent this with judicious
use of CAS, but nothing springs to mind.

To Nick's question about the specific circumstances I'm looking at, I'll
try to put it in a nutshell.

I'm writing a user notification service. The idea is that a computer (like
a workstation or an Arduino) can post a message that will be transmitted to
the user, even if they're on a different computer or mobile device. The
basic functionality is just pushing a notification through GCM, but there's
extra features: for instance, notifications can be staged over time so that
it's sent to less intrusive clients (like a notification center pop-up)
before more intrusive ones (like a noisy phone push). Also, when a
notification is acknowledged on one client it's cleared from others, so you
don't pick up your phone and see a lot of messages that you've already
dealt with. (There's a few other features that aren't germane to this
discussion.)

On the web UI, there's a list of recent notifications, updated in realtime.
This is surprisingly tricky to get right, and I'm still working on the
design. It first loads the notification list from the server and displays
it. Then, it establishes a channel (using the Channel API), and reloads
the notification list. It does this little dance so that it can give the
user a quick initial display (since establishing the channel is slow, in
page load terms), but still be guaranteed not to drop messages between the
initial load and when the channel is established.

Since the reload is almost always the same as the initial load, I'm
experimenting with caching the notification list in memcache. While I was
designing the cache flow, I was having a hard time coming up with a correct
algorithm. I figured I'd start by considering how ndb caches objects, and
realized that the documented algorithm admits the race condition I
described.

As a separate issue, I'm still trying to decide if I can use a non-ancestor
query and still have a live list of notifications, subject only to indexing
and propagation delays, but that's a separate concern.

[google-appengine] Re: 500 server error on App Engine when using OpenID Users API on custom domain

2014-07-29 Thread Joel E

Oh, I think I understand but I don't think it solves the issue. See, the 
App Engine user's API accepts relative URLs and then takes care of 
processing the call to the openID provider. Here's how my code works:

String LogInURL = userService.createLoginURL(/main.jsp, null, 
openid_identifier, null);
resp.sendRedirect(LogInURL);
I take the URL of the provider from the user (openid_identifier) and send 
it to the App Engine Users API to create a redirect URL. Then I send the 
user to the provider through that URL. The user first logs in through their 
provider but on return to my app they land on a 500 error page instead of 
being redirected through to /main.jsp. If I start the process from my 
appspot.com domain instead it goes through to /main.jsp just fine.

Thanks for trying though!

[google-appengine] Errors with OpenID2 in the users API on a custom domain

2014-06-20 Thread Joel E

I'm currently developing a Google App Engine app and have it setup with a
custom domain. Recently, I've been working on switching login over to the
OpenID 2 system built into the users API. Everything works fine until I try
it through my custom domain (codecloud.byte-games.com). The first issue was
Google displaying a 400 error when requesting OpenID login with Google as
the provider. I managed to fix that by asking Miguel Andres register the
domain manually on the deprecated Google OpenID 2 system.
(https://groups.google.com/d/msg/google-federated-login-api/eIz-i1UYhQY/1LcD2tBxUAMJ)

After that was fixed I continued my testing and found a similar issue, this
time when loging in with a non-Google OpenID on the custom domain. I
managed to implement a temp fix by redirecting users to the appspot domain
but that is far from ideal.

Basically, whenever the user finishes login with the OpenID provider and
returns to my app at
the
http://codecloud.byte-games.com/_ah/openid_verify?continue=http://codecloud.byte-games.com/

URL it displays the 500 App Engine server error page. When I do the exact
same thing except from the appstop domain it works fine. Nothing gets
logged in the logs and I have no way of controlling that so it seems to be
an error in App Engine itself. I would contact support about this but I'm
using the bronze level so I can't do that. It would be *AWESOME* if someone
at Google could look into this.

Thanks!
Joel

I'm using the OpenID option for the Users API in my web app. When I test it

[google-appengine] image service suddenly corrupting TIFF images in production!

2013-05-08 Thread Joel

images api is suddenly corrupting output when source image is tiff (1bit
group3). Code that worked fine for over a year is suddenly and unexpectedly
corrupting output images with no warning or error.
This affects all images API functions in production.

This is a silent killer for our app as we receive fax data as tiff and convert
to png before storage and other operations. The system doesn't error, the
output image is just suddenly corrupted. I have posted a detailed entry on
stack exchange with code examples:
http://stackoverflow.com/questions/16405881/google-appengine-images-api-suddenly-corrupting-images

I have also attached a sample project that shows the problem very clearly.

Please help! Our production system is totally knocked offline because of this!
:(

* How can someone else reproduce the problem?

Simply load a 2 channel 1 bit group3 compressed TIFF (a fax image) into the
images service and convert it to a PNG. The output will be corrupted. I have
created an example app to illustrate the problem:

Source image as TIFF: http://devtest-app1.appspot.com
Convert PNG (corruption): http://devtest-app1.appspot.com?convert=1
http://devtest-app1.appspot.com/?convert=1

* What is the expected output? A NOT corrupted image, as it was for the past
year.

* What do you see instead? A corrupted image.

I have filed a bug report:

https://code.google.com/p/googleappengine/issues/detail?id=9284

I have tried switching to PIL for the image conversion and PIL does not support
group3 compressed TIFFs. So that's a no-go.

Our app is using the latest version of AppEngine and runs with the python27
runtime.

Please help! We need a viable workaround, this is killing our production app.
Google's service just started suddenly corrupting images without warning. All
our live data is corrupted now! We have had to turn off our production
application until this can be resolved :(

Hi Nick,
Thanks for the response. I can verify that I have been approved
manually for my first account that I requested. The wait time was
around 2 days as you indicated just for future reference for anyone
searching this group on the sms issue. Thanks for taking care of that.

Cheers,

Re: [appengine-java] JSF 2 on GAE getting java.io.NotSerializableException: javax.faces.component.html.HtmlSelectManyListbox after trying to run from production

2010-03-01 Thread Joel Weight

Hi Daniel,

Looking at the javadoc for HtmlSelectManyListbox (
http://java.sun.com/javaee/javaserverfaces/2.0/docs/api/javax/faces/component/html/HtmlSelectManyListbox.html
)
it looks like it doesn't implement Serializable.  Since you are binding to
it in a session scoped bean, you must have a reference to it in your bean,
then it looks like GAE is trying to serialize the session, which includes
your bound instance of that class.

This is all just guesswork based on your stack trace.  If it were my code, I
would probably try to figure out how to do what I need to do without binding
jsf controls in my managed beans.

Re: [appengine-java] Re: Does GAE for Java Support JSF 1.1 or JSF 1.2?

2010-02-25 Thread Joel Weight

Amr: I asked this question on StackOverflow and Jim Driscoll from the jsf
team responded saying that JSF 1.2 should work as of build 13 if you set the
context parameter com.sun.faces.enableMultiThreadedStartup to false in
webl.xml. See here for his full response.
http://stackoverflow.com/questions/732565/can-i-use-facelets-in-a-google-app-engine-app

Puche: I'm interested in how you got around the jndi problem in JSF 2. I
ended up having to recompile jsf 2.0.2 with a small change to disable the
jndi startup stuff. I blogged about it here:
http://digitaljoel.wordpress.com/2009/12/21/jsf-2-0-2-and-google-app-engine/

http://digitaljoel.wordpress.com/2009/12/21/jsf-2-0-2-and-google-app-engine/I
don't think you see the problem if you are using an older SDK, but I'm not
sure.

I would be even more interested if you plan to move to EL 2. I couldn't get
that to work for the life of me and ended up going back to 1.x.

Thanks,
Joel

[appengine-java] Low Level API type conversion?

2010-01-11 Thread Joel Weight

I'm attempting to use the low level data api and I've seen multiple messages
on this list from people that have claimed great success with it.  I'm
having one issue that I'm wondering about.

My object has a ListKey where Key is the google type key.  As I understand
the docs, I should be able to store List... where ... is any core
datatype.  Key is listed as one of those core data types.  When I read my
entity out of the data store, I get a List of Strings instead of a List of
Keys.  Is it expected that when I read the datastore and get the property
from the resulting Entity that I have to convert all of these Strings into
Keys using the KeyFactory?

Thanks,
Joel

[appengine-java] Re: Low Level API type conversion?

2010-01-11 Thread Joel Weight

Ok, this was just me being lame. I'm using JSF and I didn't have a
converter defined for Google's Key type, so in the transition between server
and client side it was getting converted into some lame String, which was
then getting stored in the data store. So... to make a short story Long,
the datastore does support ListKey just fine and I'm still learning how
all this works.

[google-appengine] Resizing Image with Stretching

2009-07-04 Thread Joel Odom

I'm using the Image class to work with an image.  When I
call image.resize(width = new_width, height = new_height), it seems to honor
either height or width, but not both.  That is, the method maintains the
original aspect ratio without stretching.
Is there a way to stretch an image?  Thanks.

[google-appengine] Data Viewer - Kind button only displays 28 kinds?

2009-03-13 Thread Joel


In the Data Viewer, the button that allows you to select one of your
Kinds seems to be limited to 28 items.  I currently have 35 Kinds and
I can't select some of them due to this limitation.  (And I know
there's data since I can use the manual Query option to get the data.)

Is this a bug in the Data Viewer?
A built in limitation that is too small?

[google-appengine] Re: pricing / additional app slots

The Google App Engine customer service folks read this group.  If you really

grant more apps as long as they can see that you're not abusing the service.

  If you have exhausted the allocation of applications for your account,
  possibly (like so many, it seems) by creating a bunch of test
  applications, then you can follow this trick to get rid of them:
 
   * Create a new account.
 
  What if you only have one mobile phone number... :(
 

 Hrm. I can say at least that you don't need a new phone number when
 inviting a Google Apps account to develop. I have no idea about the
 non-apps workflow.


 David

   * Invite the new account to be developer for each application you want
 to shed.
   * Confirm all the invitations for the new account.
   * Log in as the new account, and remove your 'real' account from the
  developer list for each application.
   * Log out, log back using your real account. Observe applications are
  gone, and you can create more.
 
  I think this trick is semi-officially sanctioned, so I doubt you'll
  get kicked off the service for doing it (at least during the preview
  period :).

 In short, i'd like to use App Engine to return xml responses to my

 Is this allowed?


 I hope so!  I'm planning on doing the same thing! (Except with JSON :-)

[google-appengine] Django Replace Filter

2009-01-04 Thread Joel Odom

Is there a simple way to do a replace with Django?  (I want to replace all
underscores in a string with spaces.)  I can't find a built-in filter to do
a simple replace, but it seems like an obvious filter that I must be
missing.  Thanks!

[google-appengine] Re: Money sum formating

2008-12-24 Thread Joel Odom

Here's a little function I wrote that you may have:

def formatAsDollars(amount):
  dollars = int(amount)
  cents = amount - dollars

  i = 0
  reverseDollarPlaces = []
  for p in str(dollars)[::-1]:
if i % 3 == 0 and i:
  reverseDollarPlaces.append(',')
reverseDollarPlaces.append(p)
i += 1

  return '$%s.%.2i' % (''.join(reverseDollarPlaces[::-1]), int(100*cents))

 Hi,

 I know that if

 sum = 56.0

 then

 {{ sum|floatformat:2 }} will display 56.00

 How we get $560,000.00

 Thanks,

[google-appengine] Re: What is a proper way to cache values on per request basis?

2008-12-01 Thread Joel Odom

Try getting rid of the memcache in favor of a hard-coded value (for testing
purposes only).  If you're still getting high CPU usage, then the problem is
not with your use of memcache.
You can also use global variables to cache values, as long as you're
careful.

 Hi,

 I have to retrieve some entities by key multiple times during single
 request.

 I do use memcache but getting quite high CPU usage and lot's of
 warnings.

 As I retrieve the same entity by it key multiple (many) times during a
 request I wonder could I improve my code by caching results on per
 request handler instance basis? I sure I could but as newbie in Python
 I'm not sure what is the best place  way to do that.

 I could add variable to a request object (I use Django) but that will
 require to pass it to every place where I need to use it. It's too
 complicated.

 I wonder is there such a thing like a HttpContext.Current in C#? In
 ASP.NET if I want to store/retrieve an object on per request basis
 I'll simply do next:

   HttpContext.Current.Items[key] = value;
   var value = HttpContext.Current.Items[key];

 Is the anything similar in AppEngine/Python?

 Again, as a Python newbie will apreciate a working code sample.

 I think this question could be interesting to many people.

  Hi,
 
  Today we released the 1.1.6 SDK.  You can download it on our Google
 hosting
  project (http://code.google.com/p/googleappengine/downloads/list), and
  peruse the release notes (
 http://code.google.com/p/googleappengine/wiki/SdkReleaseNotes) for more
  details on the release.
 
  This release contains some notable new features, including several
 additions
  to the datastore:
 
  * You can now sort and filter on an entity's key:
 http://code.google.com/appengine/docs/datastore/queriesandindexes.htm...
  * You can now delete an entity directly using its key, without
  instantiating/fetching the Model object
  * If you specify a key_name when creating a Model, its key will now be
  available before you call put()
  * URLFetch calls made in the SDK now have a 5 second timeout, matching
  production
 
  Also, it contains a number of issue fixes, including the following:
 
  * The SDK now only supports the same headers as production:
 http://code.google.com/p/googleappengine/issues/detail?id=53
  * In production, fixed an erroneous NeedIndexError when two ancestor
 queries
  were specified:
 http://code.google.com/p/googleappengine/issues/detail?id=423
  * Calling to_xml on a model instance containing a BlobProperty returns
 that
  BlobProperty base64 encoded:
 http://code.google.com/p/googleappengine/issues/detail?id=430
  * URLFetch now uses the original HTTP method (e.g. POST) when following a
  redirect:http://code.google.com/p/googleappengine/issues/detail?id=363

[google-appengine] Global Variables / Caching Question

2008-11-20 Thread Joel Odom

Forgive me if this is a FAQ, but I did a little searching and did not find
an answer.
According to http://code.google.com/appengine/docs/python/appcaching.html,
GAE caches global variables in imported modules between requests.  I've got
a global dictionary in a module that I'm sharing between requests.  Is such
a dictionary thread safe?  In other words, if multiple users are hitting
my application simultaneously, and both may be using the same global
dictionary, am I going to encounter problems, or will GAE handle the
situation gracefully?  Thanks for any help.

(By the way, I know that the dictionary may eventually disappear or get
recreated unless I write its information to the data store.  That's okay in
the case I have in mind.)

[google-appengine] Re: Hardly anything stored in appengine - already 10 MB gone?

2008-11-20 Thread Joel Odom

Your not hallucinating.  I've seen the same kind of problem.  Apparently
there is a known issue where space is sometimes not reclaimed after you
delete a data store entity.  If you've been creating and deleting a lot of
entities, this one may be hitting you.

 Thanks. At least I am not hallucinating. I didn't do anything and the

 It would be neat if we at least had the faintest view of our files
 (like a html interface) - not the datastore, but the stuff we
 upload...html files, images, etc.

[google-appengine] My logs are starting to bite into my storage quota. Can I reclaim this space?

2008-11-15 Thread Joel Odom


In my testing this morning, I've generated quite a few messages in my

there any way to reclaim this space?  Thanks.

[google-appengine] Longer timeouts - but not cpu

2008-10-09 Thread Joel


Similar to the problem of wanting resource intensive requests...

I would find it convenient to be able to mark some of my URLs with a
general timeout for that url.  Due to using urlfetch in certain ways I
may be able to determine that my timeout should be closer to 20
seconds.  But I'm not using more than a normal amount of cpu during
this process due to the urlfetch calls.

I think this makes sense in those cases where the user of my
application expects that it may take a little longer for the response
than typical web pages.

Is this already an issue or does anyone have comments on it?

[google-appengine] Re: Fwd: New Admin Console Released

2008-09-18 Thread Joel


I like the added visibility.

But now I want to find out where my mcycles are going!

Is there an api analogous to time.time() that I can use to see how
many megacycles I've used to that point?
I would find that helpful.

 Hi,

 This morning we released a new Admin Console which includes a more
 descriptive accounting of your application's CPU stats.  We now display the
 amount of CPU consumed per request, as well as the avg amount of CPU used
 per handler.

 In addition to the CPU stats, you can see the short-term request rate per
 handler, as well as the total number of requests a day for each handler.

 Sign in to the admin console and check it out!
