[google-appengine] Re: Some questions about instances

[timh]

Which is better is subjective.  I prefer python, others java.  Things to 
consider how much existing code from other sources for python or java that 
already run on appengine are you likely to use. That would feature highly 
in your decision making process.  Performance with java seems to depend on 
startup times and how big/heavy your stack is.  Big heavy python stacks 
that do a lot at startup on appengine can have startup time problems too.

Hi Sam,

It looks like you've already asked this identical question, and haven't
provided any additional information in this second thread. Given the
technical question and answer format of your post, I'd suggest asking the
same on Stack Overflow. Make sure to provide additional details such as the
exact error message you are receiving on your site.

Thanks,
Dan

When does this exception happen? From the error message, you're trying to
encode u'\u2019' (RIGHT SINGLE QUOTATION MARK) with the 'ascii' codec. Here
is an example:

>>> u = u'\u2019'
>>> u.encode('ascii')
Traceback (most recent call last):
  File "", line 1, in 
UnicodeEncodeError: 'ascii' codec can't encode character u'\u2019' in
position 0: ordinal not in range(128)
>>> u.encode('utf-8') # you can get an utf-8 encoded binary string

I don't recommend doing that. I recommend you check where the exception
occurs and fix it.

[google-appengine] Re: Wordpress + AppEngine = PressEngine

[@Mlaynes]

nice news about this theme:
launch of the PHP runtime for App Engine = ease of use of open source 
projects like Wordpress and more.. so, apart of Quercus library to use PHP 
projects, now we have the option to implement those projects on Google 
Cloud Platform directly..

more details here:
https://developers.google.com/appengine/docs/php/gettingstarted/

sample of wordpress running on GAE platform:
https://gaeforphp-blog.appspot.com/

register an app (you'll need a GAE account)
https://gaeforphp.appspot.com/

best to all !

[google-appengine] Some questions about instances

[Sebastián Benítez]

Hi there. I'm looking to create an Android/iOS (perhaps web too) social 
application and I'm considering GAE as backend.

For what I could gather, a single frontend instance is launched when a 
request arrives. Is that instance also used (as in multiple threads) to 
serve other incoming concurrent requests or other instances are launched?

What are the benefits of using Java/Python. I'm thinking the case of the 
app being eventually successfull and needing to handle 1M/10M users. I 
would asume Java is a better fit, but considering what I've read lately 
about launch performance, I'm not so sure now.

Thank you.

Yup. I'm having this issue too. Does anyone know of a way to fix it or a 
good path to start down to solving this?

[google-appengine] How to set deadline for a PHP URL fetch?

[1moretime]

URL Fetch overview says:

You can set a deadline for a request, the most amount of time the
service will wait for a response. By default, the deadline for a fetch
is 5 seconds. The maximum deadline is 60 seconds for HTTP requests and
10 minutes for task queue and cron job requests.

Now, how can i set deadline to 60-sec ?

What kind of an exception?

FWIW, I tried with both 1.8.0 and 1.7.7 and it works for me.

Because it uses the old webapp which is just a wrapper around Django:

Since I couldn't reproduce it myself, please include steps to reproduce.
Does this also happen when you use the the guestbook app?

Can you file a bug (it makes tracking easier)?

Re: [google-appengine] Re: Memcache expiration

[Pertti Kellomäki]

Thanks. In my case the memcache entry reflects what would be the result of
a particular datastore query, so if the entry is purged the datastore query
can always be run.

[google-appengine] Re: Memcache expiration

[timh]

The main thing to remember is memcache on appengine is not reliable, 
Despite any deadline you set, items in memcache can be purged/removed by 
google infrastructure at any point and you have no control over that. 
 Having said that relatively short periods 30 minutes for expiration tend 
to be ok. Though some times apps have at times very short life spans for 
data in memcache

[google-appengine] Memcache expiration

[Pertti Kellomäki]

Hi all,

I have never used the app engine memcache before, so I would like to double
check that I understand how expiration works.

I maintain a bit of state in memcache for each client, and I want the state
to hang around as long as the client is alive, but go away after
that. Reading the docs suggests that expiration is solely determined by
insertion/update operations, so my client does a periodic .cas() on the
state to move the expiration deadline forward.

Is this a sensible implementation on app engine? My app is in Python if
that makes a difference.

The background is that clients poll for new events posted on the server.
New events are inserted in event queues in memcache for each client, with a
fallback of reading the events from datastore.

[google-appengine] Re: Error code 202

[Ian Marshall]

People might also want to star Issue 7972 (Error code 202: change
logging level from Warning to Error) at:

https://code.google.com/p/googleappengine/issues/detail?id=7972&q=Error%20202&sort=priority&colspec=ID%20Type%20Component%20Status%20Stars%20Summary%20Language%20Priority%20Owner%20Log

This feature request requests that the severity of this type of log
entry be changed from
warning to error; it's not just a warning since a user has been unable
to access the web site and got the GAE error 500 page instead.
