[google-appengine] Re: Let's defend GAE!

[Tim Hoffman]

Hi Adam

Couldn't agree more with your sentiments.  In addition to working on
fairly significant
projects with appengine, I run our small business web site on
appengine as well (www.fishandlily.com.au).

It is really a headache free environment if you get everything
sorted.  We don't have to
worry about os upgrades. Server/hardware problems etc... My wife
manages the content (again
a small cms for us) and I occasionally make some tweaks to the code
base.

With agressive use of memcache, we almost never see any of the major
problems of
increased datastore latency.

ahaha, never though of that. I just wanted to see which kind of application.

Frankly we didn't have any particular problem with the platform.
Our application is blazing fast (once it started) and the console and
other tools are fantastic.
Only problem is the db or the application down. There are lots of
complains about that here as well, no point in adding another one.


Anyway I'm happy with the explanation Ikai wrote, we can wait for a
while, for sure in the last week we had no issues, and that is almost
a first.

Re: [google-appengine] Re: Prerelease SDK 1.4.0 is out!

[Viðar Svansson]

Thank you for a great release!

Heavy frameworks like Spring MVC can be loaded really fast if you
serialize the context into cache/datastore. Unfortunately this is not
easy to do and I don't know if SpringSource is planning on making it
easier.

A blog post like that was bound to be published sooner than later.
What we need now is a counter post ;)

Cheers,
Viðar

Re: [google-appengine] Re: Let's defend GAE!

[Martin Webb]

All that GAE needs is someone in these forums to build, launch and run the next 
killa app like twitter. Once that happens people will take the platform more 
than seriously as the app will scale to millions trouble free overnight - 
sending out big signals to developers that app engine is a serious, well honed 
platform for building scalable apps. Lets hope that day comes soon, as when it 
does im sure once the limelight is on - things can only get better.
Im sure someone somewhere is hard to work on just that.

[google-appengine] Policy for instance startup

[Tomas Alaeus]

I'm curious when exactly instances are started. I have two
applications running on GAE, one of them have billing enabled. The one
with billing enabled have been stress tested and have at most started
100 simultaneous instances. The other is just for testing and staging
purposes and have never handeled much traffic.

What I experience is that the staging server never starts more
instances than needed. If a single person views pages it will never
load more than a single instance. The other one however seems to start
about 5 instances before anyone can get hot responses, and it will
continue to start up to about 10 before realizing that ~1 QPS isn't
that much traffic (the requests finish in about 100ms each).

So, why does GAE boot up lots of instances even though 1 instance can
serve the incoming traffic without a problem (the requests doesn't
even overlap, so no waiting is needed)?

I realize that this isn't a very big issue, since when it gets lots of
traffic it will indeed need all the instances. I'm just curious why it
happens.

Gae is just a subtitle, it is based on the google api's written in c,
c++, python and the datastore containers all over the world. This
distributed computing, programming model (based on open standards) is
allready one off, or the largest network on the moment.

Re: [google-appengine] Google Docs blocking GAE apps? (503 lockout: automated queries)

[Jan Zawadzki]

neither - this is 2LO.

Actually, it's both 2LO and client login.  Same error, same timeframe

Went away after about four hours, but became an extremely serious problem as
it affected a number of our apps (possibly all?)

I am loading more records later tonight, will let you know if it reappears.

Bit of a show-stopper for our schools kicking off with Google Apps
unfortunately :(

[google-appengine] App is cut several times a day

[sahid]

Hello,

Please see this chart: http://i.imgur.com/9CAnF.png (All of my users
are connected in a third part server (COMET))

My app is cut several times a day and i don't know why... I use
appstats and all of my requests are OK... in general i use less than
10 RPC by request.
my average latency is in about 120ms and in general i have less than 1
error for 100reqs.

I have several type of errors: DeadLineException, Timeout, and
"Community error (not logged)";

- The DeadLineException are directly in rapport with the "System
Status".
- The timeout error are launched from time to time with a big number
of errors during a small time (in rapport with my reqs/s)
- The "Community error" comes from time to time and the result is my
app is down...

Seriously i think the problem comes form GAE; Ok ...for "Time out and
DeadLineException" but the "Community Error" down my app
and that is terrible.

So please, you can investigate my app? appstats is launched if a
google engeneer want my identifiant i can give it.
I need to know if the problem comes from GAE or not because i can
wait... but i need to know.

APPID: devel-inchallah

Thanks a lots,
Sahid

[google-appengine] Re: Memcache/JCache across my application

[Simon]

You are going to get a JCache instance for every GAE JVM-instance
which is spun up and there's no guarantee (in fact in my experience
it's pretty unlikely) that your GAE-instance will even be up for 2
hours.  It's worth remembering that you can have multiple GAE-
instances running at the same time and take that into consideration
for your app's design - you have no idea what instance your cron job
will run on, but it will only ever work against one of your instances.

Re: [google-appengine] Re: Administrator with Google Apps account

[Brian Davenport]

To do this all you have to do is make that user account in your domain then
set it up as a app admin so you can send as that user.

Re: [google-appengine] query order and name attribute (patch)

[Peter Petrov]

Hey Robert, thanks very much for tracking and fixing this (I'm the one who
reported the second issue).

Dear Googlers, _please_ finally notice this and fix it. Named properties are
nearly useless anyway, even without this bug (because the name attribute is
not transparent as it should be, you still need to modify your queries).

[google-appengine] Is there anyway to locally test a GAE + Facebook?

[nacho]

This is more a facebook apps question, but i would like if some gae
developers have experience doing this.

I need to develop a Facebook app, and i want to do my back in gae and
my front in gwt. Easy task.

My question is this: how can i locally test my fb app?

My app must run on Facebook app's canvas (ie: iframe). So i created a
new app, put a app_id and in the canvas url the following:
http://127.0.0.1/MyApp.html

But when i go to apps.facebook.com/myapp i get a blank page. I think
that i can't test locally, so i have to deploy to appengine and put my
appengine url in the facebook canvas url. But every deploy takes me
4 / 8 minutes :(

Is there any way to locally test my fb app using gae?

Re: [google-appengine] Is it possible to download your own GAE project.I lost my laptop

[Robert Kluin]

Also, in the future, try using something like bitbucket or github.
That way you'll have version control and an "off-laptop" backup.

Re: [google-appengine] query order and name attribute (patch)

[Robert Kluin]

I agree.  Named properties are messy, it is not always clear which
"name" (short or long) should be used.  Also, just as a note, if you
make your model and exando you can use the short name in the order.

Re: [google-appengine] Is there anyway to locally test a GAE + Facebook?

[Chris Copeland]

You need a publicly accessible IP that Facebook's servers can hit to load
the contents of your canvas page.  (127.0.0.1 is a special loopback address
that is only valid on your computer.)

I suggest using a service like DynDNS to register a host name like
myapp.homeip.net and then use their tools to automatically update DNS
records with your current IP as it changes (assuming you don't have a
static, public IP for your dev machine).  Then update your Facebook app
settings to point to this host name.

If you are behind a firewall/NAT you will need to make a hole in that and/or
configure port forwarding.

When you start your local server you will need to bind it to your LAN
address instead of loopback.  Eg. "-a 192.168.1.1"

I have also found it useful to create two separate Facebook apps.  One for
testing where it points to your dev machine and one for production that
points to Google.

[google-appengine] setting up www mapping help.

[Ning Hu]

Hi All,

I'm encountering a prlbme when trying to setup www to redirect to my
domain.
Currently trying to do it under the google apps dashboard.

When I try to add the www mapping, it gives an error that says:
"Already used, please remove previous mapping first "

But the question is, how to I remove the previous mapping?  It does
not show up in the current mapping list.

All other subdomain mappings show up in this view, and seem to be
working correctly.

Do I need to tinker with eNom's zone file manually?  (I've purchased
the domain name through the app engine website)

Is there a guide on how to setup eNom's zone files to allow naked
domain and www to redirect to ppmesh.appspot.com?

Any help is much appreciated,

Thanks,
Ning

Thanks and congrats for the great release.

Will there be an option for source code download control in app.yaml.
according to the mail thread in pre-release of 1.3.8 we thought this will be
implemented, and that would be very helpful.

the feature announced now will be a very good add-on but, by default if the
config is to be on app.yaml.
Will there be any option for the creator of the app to get any versions
source code.

We have some use cases relying on this option. so please make a reply about
this, accordingly we can streamline the development process at our team,

Thanks

Martin,

This has already happened =). There are folks here in these groups who have
built very successful businesses on App Engine. You just don't hear about
them because they're not hyped in the tech blogs.

Re: [google-appengine] Prerelease SDK 1.4.0 is out!

[Ikai Lan (Google)]

You'll be able to download code, but anyone that wants to turn it off will
be able to go to their admin dashboard and push a one-way, irreversible
button to disallow this feature.

Please do not depend on this feature to do source control.

The 'sites' application has an admin screen which also allows you to
map domains to sub-sites. This does not show up on the main screen
with all the other apps. Check here, and delete the 'www' mapping.

You too JohnP?

When I pause the queues, it seems to clear up. Unfortunately I've moved
_all_ of my heavy lifting onto a 1 request/second task queue that never gets
off the ground.

I think you've got something else wrong.  Either way should work.

t1 = Test(key_name="one")
t1_key = t1.put()

t2 = Test(key_name="two")
t2_key = t2.put()

# Make some entities with references.
t3 = Test(key_name="three", ref=t1)
t3_key = t3.put()

t4 = Test(key_name="four", ref=t2_key)
t4_key = t4.put()


# Check they were saved.
t3 = Test.get_by_key_name("three")
print 'three: ', str(t3.ref.key().name())

t4 = Test.get_by_key_name("four")
print 'four: ', str(t4.ref.key().name())


# Change the refs.

Re: [google-appengine] Re: GAE down?? Thousands of 500 Request was aborted after waiting too long

[A. Stevko]

I just logged this into ticket 4113


more info on the situation with appid: ninuku-archivist

been down for 4+ hours

100% failures on all task queues (

100% failure on all mail send (low volume)

53% failures on gwt mvp dispatch request handlers

pausing the 1/s task queue returns system to stable & responsive to
user experience

unfortunately -no tasks- provides little or no user value because UI
only creates tasks to do the work (fetching facebook info & creating
xml/pdfs) - users are left hanging with nearly every action.

This couldn't have come in a worse time...
I've been getting great press in the blogs, my partner was just interviewed
by time mag, and, in the past 4 days, I got almost a thousand people to
grant my app full permission to access their Facebook profiles in exchange
for a couple of pdfs.

Please star & comment on  ticket
4113and
maybe we'll get some visibility.

I hope someone is firefighting this situation - the admin server just melted
down with repeated 500 responses
and my latest deployment just asked me to authorize.

[google-appengine] Re: app dashboard not accessible

[mscwd01]

Well this is strange, my app seems to be running better than usual and
throwing no 500 errors - it's speedy too. However, the dashboard is
down. :(

I think they need to add downtime as an official "feature" to the App
Engine as it is fast becoming one.

[google-appengine] Absolutely NO Problems Currently

[Steve]

There's been increased postings of problems on the newsgroups and
production serving issues logged in the bug-tracker lately.  But I
want to tell you that clearly there are no problems with the google
app hosting infrastructure because the system status dashboard is as
green as an old style hundred dollar bill and it clearly reports 100%
availability.

What a bad fricken joke.  Google, the LEAST you could do is
acknowledge that deployments are snafu by posting to the downtime
notify group and sticking a note on the status dashboard.  The last
note says the problems were fixed on the 18th.  Well, my site went
down due to a fubar deploy on the 20th.  And the next day.  And today
again it's hosed.

I'm real happy you all got nice bonuses but did the whole company take
off for Thanksgiving already?  I mean, what good is having a global
presence if every office takes off (early) for a US holiday.  Can't
you at least hire somebody in India (because I know turkey isn't
popular there) to keep watch on the house and post oops we done broke
it again messages?

I mean really... Come ON!

It would be helpful if the app engine status page would indicate
dashboard outage.

[google-appengine] cache login/pw for appcfg in linux

[pdknsk]

I've been using Linux before to deploy and appcfg saved the login
credentials for a few hours, but have not figured out how to enable it
since I installed it on a new system. Does it require specific python
modules or is there a setting that can be set? Thanks.

[google-appengine] Re: Is it possible to add Expiry headers to static files ?

[J]

Adding them is easy, as Robert indicated.

But be careful, not everything in the infrastructure respects them.
Perhaps I should have said, respects them too much. If you have a
static file header that is supposed to expire next Sunday, and update
the file before that time, the infrastructure is not required to serve
the latest version of the file since the expiry header has not expired
yet.

To get around this, you should implement some kind of a cache buster
(Google the term) unless the static files are truly static.

Click on the status icons (check marks etc.) for each service to get

[google-appengine] Re: Is it possible to add Expiry headers to static files ?

[Jason C]

Since static files are only updated when you push new releases, you
can add a version number into the url for the static resource.

E.g. (python/django), in app.yaml:

  - url: /__v[^\/]+/static
static_dir: yourapp/static
expiration: 365d

Then in your template, create a templatetag (or something) that
injects the current build number into the url:

  

The rendered output would look something like:

  

where 12345 is your build number.

Doing this will allow you to set very long timeouts, but still have
fresh content (e.g., on a new code push).

Re: [google-appengine] cache login/pw for appcfg in linux

[Ikai Lan (Google)]

I assume you're doing this for automated deployment? Instead of saving
these, you're probably better off using the email parameter and the --passin
param to pipe in the password.

Though it *would* be pretty cool to have deployment built in as a feature
for Google Code/Github/BitBucket checkins that pass tests.

Thanks, this works too. However I'm sure it was automatic before. I

again on further update requests for at least a few hours, using
python appcfg update /app.

[google-appengine] Re: Policy for instance startup

[nickmilon]

Not been a Googler can't help much with this.
Having said that, I suspect there is a kind of build in algorithm that
does some kind of application profiling taking into acount QPS,
response times, and other parameters which adjusts instance life time,
number of instances to start etc..
This could possibly explain the difference in behaviour between your
staging and production appls.

happy coding;-)

[google-appengine] Re: cache login/pw for appcfg in linux

[Tim Hoffman]

Hi

there is a .appcfg_cookies and an .appcfg_nag

I am pretty sure the stored user/id passwd is stored in cookies.
nag stores a property about being told about updates to the sdk.

--no_cookies prevents auth cookies from being stored, so

I would check to see if there is a .appcfg_cookies even present and is
writable.

Success. It were indeed the cookies. It had created the file, but it
was empty. I deleted the cookie, and it worked after appcfg wrote a
new file. Thanks! I don't know though why it couldn't just overwrite
the file.

[google-appengine] Re: Cannot deploy my app to the GAE

[Gaurav Vaish]

Change the web.xml and remove the reference to the DTD.
The problem may actually not be from the appengine but from the
java.sun.com server... I also faced this issue several times and found
that everytime the dashboard / appengine server was up. On scruitiny,
I found that the problem was caused because the java.sun.com server
was not available (after aquisition by Oracle).

You can change the "" lines to one line
as follows follows:

[google-appengine] DeadlineExceededError / Timeout

Is there anything I can to to avoid DeadlineExceededErrors
(model .put() or query) and other Timeout Errors? I don't care if the

about the 20.000 users a day that get an error when loading my app due

Re: [google-appengine] DeadlineExceededError / Timeout

[风笑雪]

You can use task queue to do put() operations. If you don't care about the
query result, you can set deadline for its rpc and display a proper page
when timeout.

[google-appengine] Re: DeadlineExceededError / Timeout

[Tim Hoffman]

Hi

Are these large queries and/or lot's of put's.  Have you looked at
appstats
to see if your doing these operations efficiently ?

Are you utilising caching with memcache to reduce your need for
querying all the time ?

Are you doing batch fetch's on your query results rather than
iterating ?

May be you have done all of these things, but thought I would point
them out,

Rgds

Tim

Re: [google-appengine] DeadlineExceededError / Timeout

[Alexander W.]

I thought about using taskqueues, but it's important that I get the
result of the put() operation immediately. Maybe the new channel api
will help (release 1.4.0), so that I'll use task queues for put()
operations and push an info to the user once the operation result is
positive.


At the moment I show an error page to the user aking him to retry the
operation. (ajax request)

[google-appengine] Re: DeadlineExceededError / Timeout

[Alexander W.]

Yes I've looked at appstats, looks alright so far.


Problem 1: put() operations (ajax request)


It's one put() operation per request.


Problem 2: queries (normal requests)


It's important that the results of these queries are up to date, so I
have to fetch them every time a user loads the application.


It's a simple query, but the db has more than 10M entries.

[google-appengine] urlfetch / facebook api

[Alexander W.]

When a user loads my app for the first time, I exchange his facebook
session_key for an facebook access_token, so that I can fetch his
profile information in order to create a new user account in my db.
This is done via urlfetch.


The strange thing is, that the urlfetch result sometimes is None and no
exceptions are thrown (DownloadError,..).


The Facebook Api usually never returns nothing, it returns a json error
message in the case an error occured.


Maybe I'm missing the point (I've never used urlfetch before), but it
seems strange.


Regards,


Alexander

[google-appengine] Re: Pagination using Query Cursors

[Tarun]

Hi,

I have not yet found the appropriate solution to this problem.

The idea of iterating and caching the cursor values at every start of
the page is one solution that I had also tried.
It works, but I guess it is not the optimum way to do it. There should
be a better way which has no performance issues.

[google-appengine] Re: DeadlineExceededError / Timeout

[Tim Hoffman]

Hi

A single put ajax or otherwise shouldn't take to long, are you doing
the put inside transactions, with large entity groups? That could
cause problems. This isn't a big counter or something is it ? How long
is a single put taking ? and are you getting
a Datastore timeout or some other error ?

Size/number of entities in datastore really doesn't make to much
difference,

large entities with lots of indexes will affect your write time.

Just confirming you are doing a somequery.fetch(n) on your query
results?

[google-appengine] Re: Policy for instance startup

[Tomas Alaeus]

Probably. With some more thinking I got to this conclusion:

At first, an application can utilize up to 30 instances. After having
used all those instances for a few minutes, and it still isn't enough,
GAE will increase the maximum number of available instances to 40, and
then to 50 etc. Every time it increases the number of instances it
will probably also adjust how and when it boots up new instances.

For my production app it probably tries to keep at least 10 instances
running since it thinks a huge amount of users can use the site at any
given time. The staging haven't had any rush of users, and therefore
thinks it is safe with just 1 instance running.

I would still like to hear something from a Googler. If this is how it
works then it means that stress testing the application (with a lot
more pressure than it will normally get) may lead to worse (!)
performance permanently.
