[google-appengine] Re: The Schedule Format of cron.xml

[Ian Marshall]

Thank you
-
You're welcome.


In option 1: Do you mean using *etaMillis of **TaskOptions *using  to
specify the execute time?
---
Yes.


We can trigger a TaskInit by cron and create 48 tasks in queue(every
30 minutes) to avoid chain task.
-
Good idea: I didn't think of that.


I just wish a simple syntax to support such requirement
---
Me too.

[google-appengine] Re: Memcache problem on a production application

[Per]

Hi Mathieu,

not sure if you're aware of this (it took me a while as well) but you need 
to design your application so it doesn't flinch even when memcache is 
unavailable. Try-catch everything. We had an issue at the same time as you 
as well, and it turned out that in one part of the application we had also 
forgotten to try-catch memcache errors. Just keep improving until it's 100% 
robust. Because memcache just isn't. A large scale downtime would probably 
show up on the system status page, but local issues won't.

Cheers,
Per

Did this problem occur with the regular launcher or just the experimental one?

I have very simple codes like above.. and It was working before 1.6.5
of GAE/J...

Since 1.6.5, it is working but.. it gives 404 of response... so It
keeps on retrying it.. even tho it worked..

Can anyone help me out on this??

[google-appengine] Re: Memcache problem on a production application

[jon]

This is actually a GAE bug. According to GAE documentation the
memcache service should by default log and ignore infrastructure
faults (which would be a very sensible thing to do) but it doesn't.

I opened a ticket 6 months ago (yes, half a year!)
http://code.google.com/p/googleappengine/issues/detail?id=6236

There is no excuse for leaving this broken for so long. It's an
extremely harmful bug and yet easy to fix. I've been raising this
issue every chance I get but the response from fellow GAE developers
on this group has been muted. We should be outraged, people :-)
Seriously, this bug can take down any of your sites if it happens to
link up with a dodgy memcache service. From experience this can last
up to half an hour.

Re: [google-appengine] Re: Feedback on experimental Mac Launcher for Python

[alex]

Brian, if it helps: 

create a new app and put "time.sleep(5)" as the first line of a "def 
get(self)" in a request handler. Now, run the app, click on Browse and, 
while browser's waiting those 5 sec, switch back to the Launcher and click 
"Stop". You should be able to get that freezing behavior. Well, unless 
there's something weird with my local setup. In the latter case I'd love to 
be able to figure out what it is as I really like the launcher and its 
simplicity.

If you're talking about local dev environment - that's how it is simulated 
locally. It indeed employes a push mechanism when running on production 
servers.

It's not in the release notes, but it looks like you've fixed issue

[google-appengine] Re: backing up the datastore backups

[Jason Collins]

Oh - though that won't make things "disappear and reappear" in the
Datastore Admin screen. The Datastore Admin screen doesn't inspect
Google Storage to determine what backups it has (though I think it
should).

[google-appengine] Unexplained traffic loss

[Nathan Skone]

We have over 300 machines distributed across the US calling an API once a 
minute, which means we should always have a base level of traffic of at 
least 5 or 6 requests per second.  However, today we are seeing pits in our 
requests per second graph that show the traffic dropping to zero, then 
spiking directly afterward.  We have not deployed any new code recently, or 
otherwise touched our application in any way.

This traffic pattern has doubled our costs compared to a normal day. A 
screenshot is attached.

Thanks,
Nathan Skone

[google-appengine] Re: Large latency spike, need assistance

[Nathan Skone]

I am still waiting for a explanation of this problem.  I have a bug report 
open here , 
and i...@google.com responded six days ago claiming they would look into 
the issue.  However, we have heard nothing since then.  Meanwhile, we have 
run into other unexplained reliability issues explained 
here
.

Is anyone else experiencing the same low level of reliability we are? Also, 
does anyone have any advice on how to get technical support from Google 
when experiencing connectivity issues?  I am aware of the premium support 
plan, but the price is excessive for us compared to our regular Google App 
Engine bill.

Thank you,
Nathan Skone

RE: [google-appengine] Unexplained traffic loss

[Brandon Wirtz]

If you had network issues between locations, your traffic could be less
evenly distributed, and would as a result make your app "peakier".

Set your max pending latency higher and your cost won't fluctuate when
network latency changes the instantaneous request rate.

Re: [google-appengine] Unexplained traffic loss

[Nathan Skone]

Brandon,

I do not believe this is a network issue, since each of the 300+ clients 
connects from different networks across the US, with a few overseas. These 
peaks seem to be caused by the Google App Engine itself.

Thanks,
Nathan

[google-appengine] SEARCH API: Problem in Adding Documents To An Index

[Ananthakrishnan Venkatasubramanian]

Hi,

I have been using Search API for my application so far successfully. I was 
able to add documents to index successfully yesterday.

But when I tried to execute the same today, it gave me this exception.

*Exception:*

Caused by: java.lang.NoSuchMethodError: 
com.google.appengine.api.search.Index.add(Ljava/lang/Iterable;)Lcom/google/appengine/api/search/AddDocumentsResponse;


I am trying to add only one document to an index and that its not working.

Please give me the solution to solve this problem.

Thanks.
