Re: [appengine-java] Google Plugin for Eclipse 1.3 plans

2010-02-05 Thread Kasper Hansen

I think it all sounds very good, I've been waiting for these
functionalities. Right now, I'm not using maven in my projects,
manually copying jars from target folders of other maven projects, to
the WEB-INF/lib folder of the GAE app... Sucks !!

I'll give feedback when I've tried the preview.

Cheers,

 Hey all,
 Many of you have reported incompatibilities between the Google Plugin for
 Eclipse and other build systems/project structures, most notably Maven and
 J2EE/Dynamic Web Projects.  For example, issue 1515 (Eclipse plugin requires
 fixed location for war directory) has collected well over 100 stars, and a
 similar one in the GWT issue tracker has attracted a lot of attention as
 well.  Based on this feedback, we've decided to try and address as many of
 the incompatibilities as possible with our upcoming 1.3 release of the
 plugin.  To deliver on that goal, we want to share with your our current
 plans, and also let you know about a preview build that we'll make available
 so you can test the changes for yourself and give us feedback before final
 release.
 Our plans for the 1.3 release include 4 changes designed to make integration
 with Maven and J2EE projects easier:

 The WAR directory can now be configured to be any project-relative path
 (e.g. src/main/webapp if you're using Maven).  You'll also be able to
 specify whether that directory is source-only (typical Maven/J2EE scenario),
 or whether it should also function as the WAR output directory from which to
 run/debug or deploy to App Engine.  If your WAR directory is
 input and output (which will remain the default for new Web App projects),
 the plugin will manage synchronizing the contents of WEB-INF/lib
 WEB-INF/classes with your project's build path and compiled output.
  Otherwise, we'll leave your WAR source directory alone and you'll need to
 specify your WAR output location when launching, deploying, etc (the plugin
 will remember the location once you set it the first time).
 The Web App launch configuration UI is being redesigned to allow you to see,
 and if necessary change, any of the launch arguments.  Previously, we were
 waiting until launch time to set many of these arguments based on heuristics
 that were invisible and inaccessible to you.  Now you'll be in full control
 of how your projects get launched.  Also, we're adding the capability to
 automatically migrate your launch configurations when necessary, for
 example, updating the -javaagent flag when changing App Engine SDKs.
 GWT/App Engine projects will no longer require our SDK library on the
 classpath.  This means Maven users will be able to pull in JAR files from
 their M2 repository as they're accustomed to and the plugin won't mind a
 bit.
 The severity of any problem marker generated by the plugin will be fully
 customizable via an Errors/Warnings preference page (similar to the Java
 Errors/Warnings page), letting you specify either Error, Warning, or Ignore.

 We'll also be including a few smaller features and bug fixes as well.
 What does everyone think about the 4 changes outlined above?  We've been
 testing the plugin against various Maven and J2EE configurations to try to
 ensure that we've eliminated the most critical roadblocks.  However, we're
 very interested in also having you folks take it for a spin before the
 official release date (slated for next month).  We're not quite ready yet,
 but stay tuned for a 1.3 preview build to be made available hopefully in a
 few weeks.  We'll distribute it as a zip file for dropin installation so it
 will come with the standard warnings and caveats (use with a clean Eclipse
 install and workspace, use at your risk, etc.).  However, it will hopefully
 give you a chance to give us any last-minute feedback about our changes
 before the final release.
 Thanks,
 Keith

Re: [appengine-java] how to share local_db.bin to others

2010-02-05 Thread Guillaume Laforge

I'd be curious to know what's the format of that database bin file.
That would perhaps be interesting to be able to create such local dbs
easily, for creating data fixtures for our unit and/or integration
tests.
Is it some form of SQLLite, or some custom object serialization?

 My problem is specific to cron jobs: GAE does not dispatch the cron

 simply does not have the implementation yet, your cron job scheduled
 in the test version will still be active, but yielding a bunch of
 errors - instead of calling the implementation in test.

  A feature I use a lot to compartmentalise data with Twig is versioned

  effectively you have multiple separate name spaces in a single

  starting fresh with a new data version when I update my entire

   Hi,

   There appears to be a bug - or at least undesired behavior -  
   regarding
   cron jobs. Let's say there's a test and a production (the active)
   version of an app. If you add a cron job to cron.xml in test, one
   would expect that job is bound to that specific version. Instead what
   I'm seeing:

    - the cron job is listed in the GAE administrator for both apps (ie.
   regardless of what you select in the app version dropdown)

    - the cron gets invoked on production - and fails, as that version
   doesn't have the implementation

   For me, this is clearly a problem. The documentation does not specify
   how versions relate to cron jobs... however, the docs imply it's okay
   to run several distinct versions, even with different runtimes (ie.
   mixing java and python). Based on this the only reasonable approach
   would be to bind the cron job to the specific version of the app. One
   also needs this separation to be able to test the cron job's  
   operation
   before going live.

   If running the cron job in the test version is not desired (eg. if
   the same job is already active in production), the developer should
   simply disable it in that version (either in cron.xml, or by detect
   the current version in the job implementation).

Re: [appengine-java] datacenter distribution policies?

2010-02-05 Thread Nick Johnson (Google)

Hi phracktle,

Posts like this may be better suited to the google-appengine group, since
they're not Java specific.

On Thu, Feb 4, 2010 at 7:29 PM, phraktle phrak...@gmail.com wrote:

Hi,

Can the Google team please shed some light on the issue of multiple
datacenters in various geographical locations pertaining GAE? I would
like to understand what characteristics and what level of guarantees
to expect from a GAE app, and didn't find any docs or posts on this...

1. Is static content delivered by a geographically distributed CDN?
Would make sense for latency and international bandwidth costs.

If you specify caching settings, yes, your content may be cached at the
edges of our network.

2. Does GAE launch VMs of a single app in multiple datacenters? Same
as above - latency would be quite bad for some geographical locations
without this.

No, currently we're single-homed, with failover.

3. If VMs are distributed, what's the deal with memcache? If it's
distributed, does/can it split into distinct partitions? How does that
affect atomic operations, such as increment, or things like grabTail?

4. If there's geographical distribution, how does it affect Datastore
performance and latencies?

My current (disappointing) impression based on latencies is that GAE
VMs are not geographically distributed, based on the latencies. But
would be good to get some clear information on this.

In general, it would be quite useful to be able to monitor VMs better,
eg. how many VM launches took place, where. This would provide more
insight into the operation and performance of the app... (This may
also be a stepping stone toward the pay to keep some VMs warm topic,
an often requested feature - at least we could see )

Thanks,
Viktor

[appengine-java] Where to report server down time?

2010-02-05 Thread Bob F

I tried to open http://folkertsfotografie.appspot.com and recieved
Error: Server Error
The server encountered an error and could not complete your request.

If the problem persists, please report your problem and mention this
error message and the query that caused it.

several times.  I followed the link to an app engine page, hoping that
it would be a form to tell either Google or the author (me) that the
application was down.  Is this a frequent occurrence with AppEngine?

Is there a log of application failures like this?

Eventually, the application can up (with no change in code).  My
application is written  in Grails with the AppEngine plugin.

[appengine-java] Re: Getting the size of a http request?

Thanks, Ikai. For this to work, it seems like content-length should be

detecting the number of bytes transferred (including header and URL
bytes).

[appengine-java] Persisting polymorphic classes using the low level API or Objectify

2010-02-05 Thread Shrikrishna Shrin

Hi,

I am developing an application that requires persisting of different object
categories that are all subclasses of a specific type. Say I have a super
class Vehicle and two subclasses Car extends Vehicle and Ship extends
Vehicle. Ideally what I would like to do is to be able to query across all
Vehicle objects as well as Car and Ship objects separately.

It looks like the PolyModel class  from the app engine Python API does this
( http://code.google.com/appengine/docs/python/datastore/polymodelclass.html
or http://code.google.com/appengine/articles/polymodel.html)

However, from the following thread it seems like this is not (yet?)
supported in the Java API:
http://groups.google.com/group/google-appengine-java/browse_thread/thread/99f9b92322ccf862/7b4a53d780a033cf?lnk=gstq=PolyModel+java#7b4a53d780a033cf

To get around this *limitation* I do something like this

class Vehicle {

String id;



*String vehicleType;* // indicates what the vehicle type is, eg: Car /
Ship.
*Text vehicleData;* // a blob of text that is a String representation of
a JSONObject that contains info specific to a vehicle type.
}

I am aware that one immediate flaw in my approach is that you cannot query
by vehicleType specific fields contained in the vehicleData blob. This is *
*NOT** important for my current app (I only need to query across vehicle
properties but the view on the client side depends on the vehicleType).
However, I am interested in knowing if it is possible to get around this?

The front end for my app uses GWT and basically what it does is it gets
Vehicle objects via RPC and triggers the corresponding presenter  view
based on the vehicleType. Each presenter in turn knows what to do with the
corresponding vehicleData JSON blob.

I am really not sure if this is a good approach and am wondering if there
are any best practices when it comes to persisting polymorphic class
hierarchies.

Am currently using Objectify
(http://code.google.com/p/objectify-appengine/)  for
persistence but there doesn't seem to be any built-in support for
polymorphism as yet.

Thanks,

Krishna

2010-02-05 Thread Ikai L (Google)

It's not going to be pretty, but you can manually get the size using either
getInputStream() or getReader() and just iterating until you get to the end,
incrementing your count by your buffer size each time, then counting the
final result:

[appengine-java] Re: Google Plugin for Eclipse 1.3 plans

2010-02-05 Thread Philip

This sounds like a good plan and I look forward to testing the new
plug-in.

- Philip


On Feb 4, 2:52 pm, Keith Platfoot kplatf...@google.com wrote:
 Hey all,

 Many of you have reported incompatibilities between the Google Plugin for
 Eclipse and other build systems/project structures, most notably Maven and
 J2EE/Dynamic Web Projects.  For example, issue 1515 (Eclipse plugin requires
 fixed location for war
 directory)http://code.google.com/p/googleappengine/issues/detail?id=1515
 has
 collected well over 100 stars, and a similar one in the GWT issue tracker
 has attracted a lot of attention as well.  Based on this feedback, we've
 decided to try and address as many of the incompatibilities as possible with
 our upcoming 1.3 release of the plugin.  To deliver on that goal, we want to
 share with your our current plans, and also let you know about a preview
 build that we'll make available so you can test the changes for yourself and
 give us feedback before final release.

 Our plans for the 1.3 release include 4 changes designed to make integration
 with Maven and J2EE projects easier:

    1. The WAR directory can now be configured to be *any* project-relative
    path (e.g. src/main/webapp if you're using Maven).  You'll also be able
    to specify whether that directory is source-only (typical Maven/J2EE
    scenario), or whether it should also function as the WAR output directory
    from which to run/debug or deploy to App Engine.  If your WAR directory is
    input *and* output (which will remain the default for new Web App
    projects), the plugin will manage synchronizing the contents of WEB-INF/lib
    WEB-INF/classes with your project's build path and compiled output.
     Otherwise, we'll leave your WAR source directory alone and you'll need to
    specify your WAR output location when launching, deploying, etc (the plugin
    will remember the location once you set it the first time).
    2. The Web App launch configuration UI is being redesigned to allow you
    to see, and if necessary change, *any* of the launch arguments.
     Previously, we were waiting until launch time to set many of these
    arguments based on heuristics that were invisible and inaccessible to you.
     Now you'll be in full control of how your projects get launched.  Also,
    we're adding the capability to automatically migrate your launch
    configurations when necessary, for example, updating the -javaagent flag
    when changing App Engine SDKs.
    3. GWT/App Engine projects will no longer require our SDK library on the
    classpath.  This means Maven users will be able to pull in JAR files from
    their M2 repository as they're accustomed to and the plugin won't mind a
    bit.
    4. The severity of any problem marker generated by the plugin will be
    fully customizable via an Errors/Warnings preference page (similar to the
    Java Errors/Warnings page), letting you specify either Error, Warning, or
    Ignore.

 We'll also be including a few smaller features and bug fixes as well.

 What does everyone think about the 4 changes outlined above?  We've been
 testing the plugin against various Maven and J2EE configurations to try to
 ensure that we've eliminated the most critical roadblocks.  However, we're
 very interested in also having you folks take it for a spin before the
 official release date (slated for next month).  We're not quite ready yet,
 but stay tuned for a 1.3 preview build to be made available hopefully in a
 few weeks.  We'll distribute it as a zip file for dropin
 installationhttp://code.google.com/eclipse/docs/install-from-zip.html
 so
 it will come with the standard warnings and caveats (use with a clean
 Eclipse install and workspace, use at your risk, etc.).  However, it will
 hopefully give you a chance to give us any last-minute feedback about our
 changes before the final release.

 Thanks,

 Keith

Re: [appengine-java] Persisting polymorphic classes using the low level API or Objectify

2010-02-05 Thread John Patterson


Hi Shrikrishna ,

Im not sure about Objectify but Twig supports storing and retrieving  
Polymorphic references.  Your example could be persisted out-of-the- 
box with no extra configuration.


Also Twig does handle querying on VehicleType - although you say that  
this is not yet a requirement.


Currently to query across all vehicle types you would need to issue  
multiple queries and join them.  But this is simple even when your  
results are sorted using the support class SortedMergeIterator.


BTW, to fully support polymorphic queries is actually quite a simple  
extension that I just haven't had the need for yet and so haven't  
written.  If you were willing to hack a patch I would be happy to give  
you some pointers where to start.

Hi,

I am developing an application that requires persisting of different  
object categories that are all subclasses of a specific type. Say I  
have a super class Vehicle and two subclasses Car extends Vehicle  
and Ship extends Vehicle. Ideally what I would like to do is to be  
able to query across all Vehicle objects as well as Car and Ship  
objects separately.


It looks like the PolyModel class  from the app engine Python API  
does this ( http://code.google.com/appengine/docs/python/datastore/polymodelclass.html 
   or http://code.google.com/appengine/articles/polymodel.html)


However, from the following thread it seems like this is not (yet?)  
supported in the Java API:

http://groups.google.com/group/google-appengine-java/browse_thread/thread/99f9b92322ccf862/7b4a53d780a033cf?lnk=gstq=PolyModel+java#7b4a53d780a033cf

To get around this *limitation* I do something like this

class Vehicle {

String id;



String vehicleType; // indicates what the vehicle type is, eg:  
Car / Ship.
Text vehicleData; // a blob of text that is a String  
representation of a JSONObject that contains info specific to a  
vehicle type.

}

I am aware that one immediate flaw in my approach is that you cannot  
query by vehicleType specific fields contained in the vehicleData  
blob. This is *NOT* important for my current app (I only need to  
query across vehicle properties but the view on the client side  
depends on the vehicleType). However, I am interested in knowing if  
it is possible to get around this?


The front end for my app uses GWT and basically what it does is it  
gets Vehicle objects via RPC and triggers the corresponding  
presenter  view based on the vehicleType. Each presenter in turn  
knows what to do with the corresponding vehicleData JSON blob.



Am currently using Objectify (http://code.google.com/p/objectify-appengine/ 
)  for persistence but there doesn't seem to be any built-in support  
for polymorphism as yet.


Thanks,

Krishna

Re: [appengine-java] Re: vs-accounting.appspot.com - datastore viewer error

You have an empty property of type e-mail, and that makes the datastore
viewer unhappy. You need to either use a different type that can be
non-empty (like String), or have non-empty e-mails.

[appengine-java] Are you using multiple app versions and a mixture of java and python in GAE?

2010-02-05 Thread Houston startup coder

You can essentially gain the ability to deploy multiple applications
around a single datastore if you deploy multiple versions of your app
that have different code from each other.  I'm curious as to how many
of you are doing this and how positive your experience has been so
far.

Right now, we have a lot of data processing code written in Java that
we could easily split up into at least a couple of applications that
run in the background and don't need to be synchronous with the user
interface.  I'm considering leaving that all in Java and then writing
the user interface in a separate Django or Gaelyk app to minimize boot
times of all the various apps.

I'd love to hear a bit of your story if you're deploying multiple
codebases for a single datastore...

Thanks!

Re: [appengine-java] Are you using multiple app versions and a mixture of java and python in GAE?

2010-02-05 Thread John Patterson

Hi, I split my original app into an admin app and a user app for
exactly the reason you gave - reduced start up time. In my case it
more than halved the load time of the public facing app.

I share code between the two Eclipse projects using symlinks to the
source folders. This saves a lot of time keeping the code synced and
works well with the Eclipse plugins one-app-per-project concept.

Because I am still refining my data model I need to upgrade the data a
lot which is time consuming. So I bump up the schema version number
(a Twig feature) upload just the updated admin app and process the
data in the new format. When thats complete - maybe 8 hours later - I
update the live version of the user app to use the new schema version
number.

Re: [appengine-java] Re: production memcache grabTail namespace isolation broken

2010-02-05 Thread Ikai L (Google)

Hey Viktor,

I've been doing a bunch of research on this and it turns out my original
post was incorrect. Unlike the version of Memcached that is out in the wild,
the version of Memcached being used for App Engine *does* provide namespaced
partitioning and nested namespace partitioning, with LRU expiration
implemented both globally and per namespace (not 100% sure about namespaces
deeper than root + 1). What this allows is constant time namespace flushing,
among other security features. This is the mechanism that allows App Engine
developers to all use Memcache without trampling over each others' data and
is more sophisticated than prefixing a key - allowing us to track usage per
user without have to iterate over a key range.

I'm going to file a bug internally against this mirroring your bug report.
It's possible we just haven't exposed the interface for nested LRU grabTail
correctly. I'll update the external bug if I hear anything.

 Hi Ikai,

 Any updates? (I see there's a mention of adding grabTail in the 1.3.1
 release notes - though it has been there in 1.3.0 already)

 In the meantime, I have implemented the queue with a head/tail
 pointer, using the increment call... This works, but if grabTail
 worked as advertised, that would be more elegant.

Grabs (atomically get and delete) items off the tail of LRU list.
This can be used to implement queue system with high throughput and
low latency, but low reliability. Current namespace should be set and
not empty for the service. For each namespace memcache maintains a
separate LRU list.

[appengine-java] Re: datacenter distribution policies?

2010-02-05 Thread phraktle

Hi,

Thanks. I have filed an enhancement request to support multiple
datacenters. Please vote if you'd like to see improved latencies :)

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

GAE apps are currently pinned to one datacenter (with failover).
Please provide an option for VMs in
multiple locations in the world to keep request latencies low. Current
round-trip times of requests
are really high from many locations (on a simple http ping ~100ms in
the  US, ~200ms in EU -
presumably higher from Asia). Presumably this would also reduce
bandwidth costs for Google.

This may introduce some new consistency issues to be aware of (eg.
memcache would need to split,
the DS eventual consistency may become more eventual, etc), but
would still be quite simple to
manage for developers.

(As a simpler workaround, being able to configure the geographical
location for an app would be
helpful - at least one could partition the app by geography with
different URLs).

Thanks,
  Viktor

  Hi,

  Can the Google team please shed some light on the issue of multiple
  datacenters in various geographical locations pertaining GAE? I would
  like to understand what characteristics and what level of guarantees
  to expect from a GAE app, and didn't find any docs or posts on this...

  1. Is static content delivered by a geographically distributed CDN?
  Would make sense for latency and international bandwidth costs.

 If you specify caching settings, yes, your content may be cached at the
 edges of our network.



  2. Does GAE launch VMs of a single app in multiple datacenters? Same
  as above - latency would be quite bad for some geographical locations
  without this.

 No, currently we're single-homed, with failover.







  3. If VMs are distributed, what's the deal with memcache? If it's
  distributed, does/can it split into distinct partitions? How does that
  affect atomic operations, such as increment, or things like grabTail?

  4. If there's geographical distribution, how does it affect Datastore
  performance and latencies?

  My current (disappointing) impression based on latencies is that GAE
  VMs are not geographically distributed, based on the latencies. But
  would be good to get some clear information on this.

  In general, it would be quite useful to be able to monitor VMs better,
  eg. how many VM launches took place, where. This would provide more
  insight into the operation and performance of the app... (This may
  also be a stepping stone toward the pay to keep some VMs warm topic,
  an often requested feature - at least we could see )

[appengine-java] Best option to scope transactions for fast RPC calls

2010-02-05 Thread Bourke Floyd IV

I'm working on a RPC like service and I was wondering if I picked the
right method to implement my classes that I'll be persisting to the
datastore. Also note that I allow users to create their own keys used
to lookup their data.

Currently I have a MerchantClass Entity that holds my merchants and a
DataWrapper Entity that holds the data they are looking for. Several
merchants could be making requests at the same time, and as I
understand it could cause (read/write) transactions to fail. I don't
have any relationships at the moment because I don't want opening a
Transaction on the MerchantClass Entity to prevent read/writes to the
DataWrapper Entities. However, I do want to limit the scope in a more
modular way to keep a merchants transactions from interfering with
other merchants transactions.

My overall goal is speed if I just need to keep it simple. Currently I
can get a merchant and verify their status, then get their requested
transaction without any problems. But I merchants can't register two
transactions with the same key, and I'm a little worried that one
merchant could interfere with the success of another merchants
successful transactions.

Thanks for input!

Re: [appengine-java] dynamic class load

[appengine-java] Re: production memcache grabTail namespace isolation broken

2010-02-05 Thread Peter Liu

Hi Ikai,

If the grab tail do intend to only return objects belong to a specific
namespace,
it will be nice if the memchace clear all function only delete
objects in a specific namespace as well.

At first I thought the clear all don't respect namespace is due to
memcache implementation constraint.
But if grab tail can respect namespace, there's no reason why clear
all can't respect namespace right?

It will be very helpful if we can flush a specific type of objects
(that belong to same namespace) in memcache.
Right now we either flush everything or maintain a set of keys and do
a delete all.

Thanks.

 Hey Viktor,

 I've been doing a bunch of research on this and it turns out my original
 post was incorrect. Unlike the version of Memcached that is out in the wild,
 the version of Memcached being used for App Engine *does* provide namespaced
 partitioning and nested namespace partitioning, with LRU expiration
 implemented both globally and per namespace (not 100% sure about namespaces
 deeper than root + 1). What this allows is constant time namespace flushing,
 among other security features. This is the mechanism that allows App Engine
 developers to all use Memcache without trampling over each others' data and
 is more sophisticated than prefixing a key - allowing us to track usage per
 user without have to iterate over a key range.

 I'm going to file a bug internally against this mirroring your bug report.
 It's possible we just haven't exposed the interface for nested LRU grabTail
 correctly. I'll update the external bug if I hear anything.

 Hi,

 In this case grabTail would be quite useless, as one cannot really
 construct queues with it (ie. it would just force removing items from
 all namespaces that wouldn't even expire otherwise). The
  documentation
 also implies that there's a separate LRU list per namespace, which
 does make sense, but is not what's happening in production:

http://code.google.com/appengine/docs/java/javadoc/com/google/appengi
  ..
.)

 Grabs (atomically get and delete) items off the tail of LRU list.
 This can be used to implement queue system with high throughput and
 low latency, but low reliability. Current namespace should be set and
 not empty for the service. For each namespace memcache maintains a
 separate LRU list.

By GAE plugin are you referring to the Maven GAE plugin or the Google

Anyhow, a while ago I blogged about Eclipse, GAE and Maven working
