[appengine-java] Re: Incoming mail handler runs slow
To avoid these long loading requests you can either make your app faster to load or keep it warm by pinging a page with a cron job, say every minute. Cron jobs will only work on the default (live) version so I wrote a PingTaskServlet that simply places another task in the queue and finishes. On Dec 30 2009, 2:13 pm, Derek Battams de...@battams.ca wrote: I've written an incoming mail handler and it works, that is, it does what I want it to do, but it runs slow, very slow. However, I'm not sure why it's so slow because I'm using theQuotaServiceto time how long the doPost() method of my email handler servlet is running and it's returning 0.00 CPU seconds and 0.04 API seconds, yet the logs routinely report the requests taking over 1ms. I notice that if I fire two emails in rapid succession at my app then usually the first one reports as taking 1+ ms to run then the second one will run in under 150ms, which is confusing me even more. It's almost like the app is having to spin up on every email it receives, but 10+ seconds for the spin up seems way too long. Is there something I should be watching out for when writing incoming email handlers? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: custom vs. generated keys / storage?
Hi, I'm using the low-level DS API, thus short names for kinds, etc, and my keys are already quite compact. The encoded version is in fact significantly longer than my own key. So it would optimal, if DS did not try to second-guess and bloat my PKs. How do you know that DS doesn't actually store both versions? Do you know how to decode the DS key? Regards, Viktor On Jan 5, 5:54 am, jd jdpatter...@gmail.com wrote: The encoded Entity Key is a representation that includes your key name, entity kind, ancestors and app id - encoded into a form that is safe to use in urls etc. Keeping your keys small and kinds small (i.e. using short class names) will reduce storage space of keys in the DS. In Twig (i.e. not JDO) you can keep the names of your classes as you like and then override typetoKind(Type) to return abbreviated names. I found that this saves a significant amount of space in my app that has many relations between entities. http://code.google.com/p/twig-persist/ On Jan 4, 5:01 pm, phraktle phrak...@gmail.com wrote: Hi, I'm generating my own entity keys, with new Entity(Foo, myId).

[appengine-java] Re: why my app on GAE first access is so slow
I use a task to ping itself every minute... no need to use external servers. I find that one minute seems enough but that occasionally there are still loading requests as Google serves my request from a different server - maybe to rebalance load? The app is much more responsive now but I assume that the only real solution is to speed up the start up time.

Especially since it does enhancement before hand, it should write out a manifest of exactly which classes need to have metadata constructed. _or_ (haha) the metadata could be pre-built as well. The plugin registry is for registering *plugins* (for DataNucleus - of which GAE/J provides one - as per an OSGi plugin mechanism), not for what classes are being persisted. There is (currently) no way of defining which jars are scanned - classpath getResource() calls. In traditional systems nobody in their right mind would want to restart an app continually. But rather than even think about such things, why not demonstrate it with facts. The log tells you timings, for plugin loading, and then for loading metadata, and other things. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] SQL to Datastore Query object
This is likely a common scenario and I'm wondering if someone has already written some code to do this that I can steal. I'm using the low-level datastore API. In my app, users will be entering a SQL where clause. For instance: category = Java and rating 5 This translates to the com.google.appengine.api.datastore.Query object as such: Query q = new Query(a kind); q.addFilter(category, Query.FilterOperator.EQUAL, Java); q.addFilter(rating, Query.FilterOperator.GREATER_THAN, 5); Has anyone written a generic library that does this translation?

Re: [appengine-java] SQL to Datastore Query object
I've written such a translater that implements a subset of JDOQL: https://code.google.com/p/lowlevelquery/ https://code.google.com/p/lowlevelquery/There's really no documentation other than the source code, which is a single class: https://code.google.com/p/lowlevelquery/source/browse/trunk/src/com/newatlanta/appengine/datastore/LowLevelQuery.java https://code.google.com/p/lowlevelquery/source/browse/trunk/src/com/newatlanta/appengine/datastore/LowLevelQuery.javaThe LowLevelQuery class contains a number of static methods that let you execute a JDOQL-like query string directly; for example: ListEntity results = LowLevelQuery.asList( select from myKind where category = 'Java' and rating 5 ); LowLevelQuery also implements the PreparedQuery interface; you can create a LowLevelQuery instance from a query string and then use it just like you would a PreparedQuery; for example: PreparedQuery myQuery = new LowLevelQuery( select from myKind where category = 'Java' and rating 5 ); ListEntity results = myQuery.asList(); Let me know what you think.

[appengine-java] How can I get to the Google App Engine Dashboard?
I am trying to deploy an in-development application, so that I can see the Users service in action. I went to http://appengine.google.com/ and created a new application (two, actually). I know that they went through because when I checked the name availability before-hand it was available and then after I hit Create those names were no longer available. I received no error or confirmation message when I hit create, it just directed me back to the Welcome page. The only option on the Welcome page is the Create an Application button. All links point to http://appengine.google.com/ but that only takes me to the welcome page, not a dashboard. I also tried deploying to the newly created applications, and it says the deploy was successful but nothing loads on those URLs (http:// homecook-in.appengine.com). There is an image of a dashboard on this page (http://code.google.com/ appengine/articles/domains.html) but I can't seem to find anything like it.

[appengine-java] Re: log4j logging everything as INFO even though I'm doing log.error(xxx);?
Found this from the GAE docs (http://code.google.com/appengine/docs/ java/runtime.html#Logging): Lines written to the standard output stream are logged at the INFO level, and lines written to the standard error stream are logged at the WARNING level. Any logging framework (such as log4j) that logs to the output or error streams will work. However, for more fine- grained control of the Admin Console's log level display, the logging framework must use a java.util.logging adapter. So, looks like if you want anything other than INFO or WARNING, ya gotta use java.util.logging. cheers Bill On Jan 4, 2:12 pm, Tb tho...@bertranfamily.com wrote: Hi, I switched tolog4jin my app because of the (supposed) ease to send out emails with log traces but it's not coming out right in the GAE log console.

[appengine-java] Re: Exception When Uploading Application To AppEngine
I'm seeing the same problem. I am not able to upload any generated GWT .cache.html files to the server. The upload is working fine when I remove all .cache.html but failed on any .cache.html file. The generated GWT file size is about 450 Kb. The previous GWT version file was possible to upload the file size was about the same.

Re: [appengine-java] how to send data in blobstore as mail attachment?
I haven't tried this, but...the BlobstoreService.serve() method takes a javax.servlet.http.HttpServletResponse instance as a parameter. My guess is that BlobstoreService.serve() simply invokes HttpServletResponse.getOutputStream() and then writes the data to the output stream. You could create your own implementation of the HttpServletResponse interface that simply writes the output to a byte array (java.io.ByteArrayOutputStream). You could then retrieve the byte array and do whatever is needed to send it as an attachment. Something like this: ByteArrayHttpServletResponse response = new ByteArrayHttpServletResponse(); BlobstoreService.serve( myBlobKey, response ); byte[] data = response.toByteArray(); Attached is a quick-and-dirty skeleton for ByteArrayHttpServletResponse that should get you started.

[google-appengine] Advantage of GAE over PHP/MySQL please
I love all things Google, but I'm wondering if I should put in effort to migrate to Python, Datastore and GAE. My non-commercial app has two distinct text forms: one is a radio selection and one is a text string that gets exploded and is searched in elseif statements against arrays. The original message is posted to 2 tables in MySQL: one with entire message, and another with exploded array words. This second table is queried for most common words and echoed in a datatable. Both of these forms must be in same app. My app also uses geo location and css/js libraries. I'm confused about Django templates; I did not see any CSS/JS templates per se in the docs; does a beginner do best with static CSS/JS files? The attraction of GAE seems to be doing everything in one interface/ set of tools, and I'd like to keep it that way: I don't need a bunch of links and 3rd party apps.

[google-appengine] Re: Advantage of GAE over PHP/MySQL please
I have been thinking about this very topic, even (re)considering PHP. :) You might want to look into using Django, or one of the other Python web frameworks, instead of the modified version running on AppEngine (the same could be said for the Java flavor). There are a couple of free hosting services available. While not deep into AppEngine; my current impression is that AppEngine needs more time to mature as a development target. Though some things are easier, a lot of time is wasted working around old bugs, design limitations, and incomplete implementations. Server status information is also lacking, and feels more like a marketing mindset, where an honest 'five nines' mindset would be more useful. In my experience, the development speed benefits of Python (and Django) are lost to AppEngine trivia. The promise of high scalability for data isn't exclusive to AppEngine, especially when memcached is the first line of defense, so even that is not an exclusive win. -- G paulmo wrote: thanks for links.

[google-appengine] Re: Anyone operate a heavy-traffic large-scale web service on app engine?
Well it depents on a lot of factors (i.e. memcache usage, site's optimazation, sites use profile etc.) For my site ( geognos.com ) bandwidth is the main factor for the time been, but there are a lot of things I can optimize to reduce it, then I have to think of minimizing requests may be. For sure there are a lot of things you can do to minimize costs with App Engine. Happy coding !

Re: [google-appengine] Re: Advantage of GAE over PHP/MySQL please
I second G's opinion. It is far to easy to spend days designing and coding to solve things that should not need solved at this high of a level. You could get yourself some real fine hosting with the money you could save spending your time on more valuable things. Right now I am heavily using app engine, and I really like it in general. But some days it is very frustrating.

[google-appengine] SSL with my own domain
Over a year ago when Google announced SSL support they said it wouldn't be supported with custom domains. (http:// googleappengine.blogspot.com/2008/10/announcing-https-support-for- appspotcom.html). This appears to be the case still today. However, they offered some hoped in their statement: You may be wondering why we're only supporting appspot.com right now, and not arbitrary Google Apps domains. This has to do with fundamental limitations in the SSL protocol. We're currently investigating workarounds for this using e.g. SNI, which provides a viable solution for newer browsers--we'll keep you posted! So, 1.25 years later, any progress or encouraging expectations? I ask because I'm working on a project due in 6-12 months that has a business requirement of supporting a custom domain name over https. If there's a reasonable chance it will supported it by then, I might stick with AppEngine and save the decision point for later. If not, I might as well not waste my time and will bail on AppEngine right now. Thanks! -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Transactions in hierarchical entity groups
Are there any benefits for running transactions on entities that are grouped more hierarchically? Say, for example, i run a transaction that only modifies a 'leaf' group of 100 entities. Is this different if the entities are located under /root/group1/somegroup vs. /root/ group1/group2/somegroup? It seems from the storage breakdown article that more indeces are generated for the second layout, i was just wondering if transactions themselves work any differently. (The data would still have to be stored together, but maybe in the above example any transactions that only operate on group2 and above could run concurrently with the example transaction?)

[google-appengine] api to determine if application is running on a development server?
Hello all: I've been fooling with AppEngine and the Google Maps APIs, and I'm running into a bit of a snag. The Google Maps APIs require a 'key' url parameter. The key parameter is hashed to your domain name, so if I've got a img tag from localhost, the key differs than from when I'm running on the Google servers. I'd like to programmatically switch the key depending on whether I'm running in the development server on my localhost, or on Google's infrastructure. Does anyone know an API that I can call that will tell me if I'm running in debug mode or not? Specifically, I'm looking for (in python): _LOCALHOST_KEY= 'ABQInfs7bKE82qgb3Zc2YyS- oBT2yXp_ZAY8_ufC3CFXhHIE1NvwkxSySz_REpPq-4WZA27OwgbtyR3VcA' _MY_DOMAIN_KEY = 'xyzpdq' def GoogleMapsKey(): if IsRunningLocalHost(): # What's this API? return _LOCALHOST_KEY return _MY_DOMAIN_KEY Thanks in advance.

[google-appengine] Best way to model relations
Hi there, I just started writting my first app after reading some documentation and tutorials. Looks like an exciting platform to develop on, but there're many things I still have doubts about. I used to develop in PHP/MySQL, and I quite don't get how should I proceed in order to get an efficient relational model. To simplify things, I have two kind of entities: Artist and Photo.

In my table-shaped mind, I would model three kinds of entities (Artist, Photo, ArtistPhotoRelation). Would this approach be the right thing in GAE/datastore?

[google-appengine] Re: Using memcache effectively
It probably depends on the type of application, but memcache does not
help you much if you have a lot of customized output (which are
different
from one user to another).
My application (social network application) has a very similar
requirement,
and I am solving this problem by doing following:
1. Break the data into pieces, so that each data is identical to all
the users,
2. Assign a unique URL to each data, and cache them in memcache using
the URL as the key,
3. Write some JavaScript code on the client side and construct the
custom page
by retrieving those data using AJAX (typically in JSON format, but you
can use HTML-let as well).
In other word, the server side of code is mostly acting as Model (in
MVC), and
the JavaScript code on the client side is acting as Controller.
I found that this architecture works really well with App Engine and
memcache, allowing me
to keep the cache hit rate very high (95%) and the average access
time to below 100 cpu_ms.
By the way, please aware that you still need to put some access
control on the server side (above memcache).
For example, the profile of each user can be accessed via http://
myapp.appspot.com/profile?uid={user_id}
(which can be cached in memcache), you want to make it sure that only
friends can access that profile.

My app may display a lot of different output for a given page

My current scheme is to estimate that a given user's output might be
useful for, say 10 minutes, after which time the user has probably
gone away so there's no point caching it. It's not that the content
is invalid after 10 minutes (I explicitly clear memcache if content
becomes invalid). Rather, I'm trying to aid memcache in determining
what it can get rid of.
Is this a good idea, or am I interfering with memcache's algorithm?
It may all depend on the exact details of the application, but I'm
wondering if there any general advice on memcache usage.

[google-appengine] Re: Best way to model relations
First of all, please remember that GAE/database is an Object-database,
not a Relational-database. You can design your database with
relations, but you will likely hit a roadblock later if you heavily
rely on relations (because of the lack of JOIN and the performance
problem of nested queries).
If I were you, I would simply create two models (Artist and Photo),
and have the artist property on Photo class, which is just a
reference to an Artist entity (ReferenceProperty). If you want to
show all the Photos done by a particular Artist, you just need to
query it (Photos.all().filter('artist', ...)).
Alternatively, you could specify the Artist entity as the parent
entity of each Photo, which essentially creates an entity group for
each Artist - which has pros (transactions) and cons (possible
performance hit because of transactions).
Third alternative is ListProperty, but this is difficult to do it
right without putting them in an entity group (which is alternative
two)...

This seems to work well, although I haven't tried sharing models yet.

you setup the app.yaml to send urls starting with /admin/ to a python
file that loads app-engine-patch and everything else to a main.py that
loads webapp.
something like:
- url: /admin/.*
script: app_engine_patch_loader.py
login: admin
- url: /.*
script: main.py
secure: never
Then in your django urls.py handle /admin

This is probably a pure Python question.
Is it possible to use a different framework depending on what hostname
the
request was made to? For example:
api.mydomain.com (API service) - webapp
admin.mydomain.com (Backend administration) - app-engine-patch (AEP)
The data model needs to be the same for each framework (worst case would
require a duplicated models.py file, which is ok).
We want AEP for its admin capabilities for admin.mydomain.com, but we
want
responses from api.mydomain.com to be as fast as possible so we'd prefer
to
use webapp, which responds faster than AEP on cold requests (requests
where there is no app caching yet).
