[appengine-java] Re: DEPLOYMENT FAILING AGAIN
Hi, I don't know why the pre-compilation has to be turned off - as far as I understand it, this activity occurs on the Google servers and it's there that the problem occurs.

[appengine-java] Re: Synchronized reads/writes on a memcache variable
Hi,
I think the following should work with the following caveats:
- there's a small danger that if the server blows up before it
releases the lock, that no threads would be able to update your cache,
but since it's only a cache of data. This is easily mitigated by
introducing a task which periodically resets the lock.
- I still believe that there's the possibility that separate instances
will get a non-updated object, even if you use the locking, since I'm
assuming it takes x-amount of time for the changes in MemCache to
propagate throughout the instances. I may be wrong in this assumption
however.
Anyway, your code would go something like:
boolean lockAcquired = false;
try {
lockAcquired = acquireLock();
doStuff();
} finally {
if (lockAcquired) {
releaseLock();
}
}
With the locking code being:
public static boolean acquireLock() {
boolean lockAcquired = true;
try {
while (increment() != 1) {
decrement();
Thread.sleep(500);
}
} catch (Throwable t) {
// Log error
lockAcquired = false;
}
return lockAcquired;
}
public static void releaseLock() {
decrement();
}
private static void decrement() {
MemcacheServiceFactory.getMemcacheService().increment(LOCK,
-1, 0L);
}
private static Long increment() {
return

}

[appengine-java] Re: Synchronized reads/writes on a memcache variable
I considered the increment decrement approach, but it creates a race
condition with the counter. Having many different threads/tasks
trying to grab the lock at the same time could increment the number
above one, even when no one has the lock because there is still a
period of time between the increment() and decrement(). Remember,
these are RPC calls going over the network. If any part of that
interaction is slow, there will be even longer periods between the +1
and -1. I think this method errs on the side of accidentally locking
when there isn't a lock. The only negatives I see would apply to any
lock that's implemented in a cache.

[appengine-java] Re: Synchronized reads/writes on a memcache variable
I guess it depends on how much throughput you're expecting through the
bit of the system which requires the lock - I agree that if there is
huge contention then this isn't the way to go, although I'd argue that
you should be changing your design anyway since synchronizing across a
distributed architecture for a lot of threads is just unadvisable.
Memcache API calls currently take ~3ms according to the status page -
running a quick (and dirty ;) ) test with 100 threads attempting to
lock using the above method averages out at ~40ms for one of the
threads to obtain the lock. If the API call times increase from 3 to
10ms, the time taken for one of the threads to obtain the lock
actually decreases to ~30ms! The biggest risk you run is that because
it isn't FIFO, there may be a large portion of time before a
particular thread obtains the lock and so it may time out.

[appengine-java] Re: Memcache entries - available how soon after entry?
So using UUID's class scope static variables I can now tell which JVM services each request. What I've confirmed is that at least when using reserved instances (Always On), Memcache entries are only found within the same JVM instance that created the cache entry. So I only get a cache hit if the next request goes to that same JVM. Is this expected behavior from Memcache, or should I raise a bug report? I pictured a highly-distributed memory cache available to the entire application. If it's per-JVM, I'm not sure why one wouldn't just use a Singleton or something to cache data, or why GAE RPC would be required when invoking the Memcache API.

[appengine-java] Re: storing unowned objects(one to many) in datastore
Hi,
If they don't belong to the same entity group, you will raise an
exception by trying to store 2 objects in a single transaction.
2 ways to handle that:
a) you make Mobile belong to same entity group as Person so you'll
be able to store both in a single transaction. I understand in your
question that you can't go this way.
b) you store one let's say Person in first transaction and during
this transaction, you start a task as part of the transaction: You
can enqueue a task as part of a datastore transaction, such that the
task is only enqueued—and guaranteed to be enqueued—if the transaction
is committed successfully. Tasks added within a transaction are
considered to be a part of it and have the same level of isolation and
consistency. as said in
http://code.google.com/appengine/docs/java/taskqueue/overview.html#Tasks_Within_Transactions

[appengine-java] Re: how to open an instance of a class
Hi, What you are trying to achieve is based on the reflection capabilities of Java and mainly the class java.lang.Class.

Re: [google-appengine] Hashing Keys
Calculating MD5 is very fast in GAE: from time import time from hashlib import md5 s = '1'*100 t = time() for i in xrange(100): md5(s).digest() print time() - t result: 1.469063 I remember the key name is limited to 500 bytes long, so it may exceed if you combine several keys into one. -- keakon My blog(Chinese): www.keakon.net Blog source code: https://bitbucket.org/keakon/doodle/ On Wed, Dec 15, 2010 at 2:43 PM, johnP j...@thinkwave.com wrote: I need to create a large amount of records which relate three other entities. Just for example, take 100 people; 100 days; and 100 restaurants. To create a record for an intersection of a person/day/ restaurant, it's possible to create keyname of person.key()+day.key() +restaurant.key(). And to retrieve records, it's easy to generate a list of keys and use a db.get(). In the internet somewhere, I read a comment by Nick Johnson saying that long keynames are inefficient, and that it can be a good idea to use a MD5 or SHA1 hash function to shorten the key name. My question is, how expensive are the MD5 and SHA1 functions? For example, if I need to generate 100 keys for each view (e.g. to retrieve people who visited 1 restaurant in 1 day, I can generate 100 keys and db.get() that list) - is it cheaper to use the MD5 hash to keep key_names shorter?

[google-appengine] Re: Downloading and processing an archive
Unfortunately the standard ZipFile module in Python only supports extracting to a file; GAE doens't allow writing files however. You'd either need to find a package that supports extracting files to a variable, or write your own. The data could then be put into the Datastore or Blobstore. Of course that approach would have issues if the files are big, but sounds like they wouldn't be if the archive is only 30 megs. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Re: Query filter using an entity's inline property
You want something like (Where N is some number):
Select * from myModel Where Prop1 + Prop2 N
No do that here impossible in GAE.
Just change the question_ttl property into expiration_timestamp (or
maybe us a nice short prop name) and calculate that future expiration date
when the entity is created (and recalculate it if 'question_ttl' ever
changes).
So you just need to query for:
WaitingQuestion.all().filter('expiration_timestamp ', datetime.now())

[google-appengine] Domain Puzzle

I'd like requests to www.kaon.ws to end up going to www.kaon.com. www.kaon.com is in google app engine. kaon.com is a google apps for business account. I added kaon.ws as a domain alias in the kaon.com google apps control panel, and did the DNS thing to verify it. It says that the domain is verified, but on the Domain names tab in the apps control panel, there is a yellow triangle ! sign on the line for kaon.ws and a link to Activate Domain Alias. When I click that link, I get to a page that says the domain is verified. But the yellow triangle remains in the tab page. When I try to tell google app engine that my kaon.com (appid kaoncom) app is handling kaon.ws, it says Sorry, you've reached a login page for a domain that isn't using Google Apps. Help? (Note that if you go to kaon.ws without the www, I'm currently using a redirect server to get you over to www.kaon.com; it's the straight www.kaon.ws that I'm trying to get GAE to handle.) -Joshua -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] etags and webkit's response -- any way to disable in GAE?
Situation: running a Google App Engine site with my static content's
default_expiration set to 14d
Problem: in Chrome and Safari, visiting a URL (not reloading, just
putting the cursor in the address bar and hitting Enter), causes a ton
of requests to be fired with If-None-Match headers. The responses are
always 304 Not Modified, as expected. I can watch these requests get
fired in a debugging proxy like Charles or Fiddler.
Want: to avoid these requests and 304 responses entirely for static
content -- simply trust the browser's cached content when it's
available.
We use the standard cache static content for a really long time,
we'll take care of appending ?version={version} modifications to our
query strings when we need to bust the cache system, so we'd really
like to avoid the 304's.
Belief: I think this is caused by the etag header that app engine
sends down with every static content response. The app engine SDK does
not send this header down, and I don't see this 304 behavior when
messing around with the SDK.
Any advice? Can you turn off etags for app engine's static content?

It works fine with Chrome 7 and Safari 5 on Windows XP in my app, no any

Have you checked the static files if they had an Expires header?
Also don't enable resource tracking for webkit which will always request for
all the resources, just check the background logs.

We use the standard cache static content for a really long time,
we'll take care of appending ?version={version} modifications to our
query strings when we need to bust the cache system, so we'd really
like to avoid the 304's.
Belief: I think this is caused by the etag header that app engine
sends down with every static content response. The app engine SDK does
not send this header down, and I don't see this 304 behavior when
messing around with the SDK.
Any advice? Can you turn off etags for app engine's static content?

Re: [google-appengine] how can i write Arabic in app engine
Hi, I don't know what framework are your using.
Generally speaking, you should set Content-Type:text/html; charset=UTF-8
header, and make sure you output UTF-8 encoded sting.
If you are using webapp, it will look like this:
self.response.headers['Content-Type'] = 'Content-Type:text/html;
charset=UTF-8'
self.response.out.write(u'something in Arabic'.encode('utf-8'))

Just change the question_ttl property into expiration_timestamp (or

So you just need to query for:

Yes, they have the proper Expires headers.

it appears as though expires is overruled by the Etags header and its

Hi Nick,
Task schedule delays (best effort) are expected but this is not the case.
Take a look at the log excerpt below which shows a task with 6 reties.
Retries are perfectly timed on flat 20sec back off schedule. In other words
I have never seen task reties follow what I put in my queue.yaml. Instead
they *always* do 20 sec backoff.
Another fact that might help is this has not changed at all with SDK 1.4.0
release. This picture was exactly the same before the release.

queue:
- name: default
rate: 20/s
bucket_size: 100
