Re: [google-appengine] Uploading a json file from local computers. URLfetch?
Need to look at multi-part post data
http://webpython.codepoint.net/cgi_file_upload
But instead of saving the file you want to process (parse) the file.
Beware make sure your parse expressions are simple. GAE does not like
compute hogs.

Hi. I am trying to develop a web service which users can upload json files
and modify the data.
Users create json files at local computers, and in the web service page,
browse the path to the files and press 'upload'.
Then, a python handler parses the file contents and make necessary changes.
My question is the process of uploading the files from local computers.
Am I supposed to use 'URL fetch' API? by indicating the URL to the local
file storage?
Or is there any other possible way to achieve this?

[google-appengine] Re: Startup time exceeded...on F4?!
I did some thinking about this problem, and it occurred to me that we might be going at this the completely wrong way. Could we reverse- bloom instance startups? Here's the basic idea. If apps need to load in/process a bunch of stuff at startup, why don't we give them the processing power to do that, but only at the time of startup? Suppose we start up an instance. For the first 30 seconds of that instance, we give it F16 ranking (that is, 4 times the power of a current F4 instance). For the next 30 seconds, the instance gets F12 ranking (3 times F4 power). The next 30 seconds, the instance gets F8 ranking (2 times F4 power). After that, the instance gets lowered to F4 and remains there for the rest of its lifespan. For the first 90 seconds of the instance's lifespan, it gets turbocharged, and should be able to handle all startup processes and a few initial requests. The scheduler doesn't need to change; it can continue feeding requests into cold instances, because even cold instances will tear through their startup and handle the requests. Even if this turboboosted time was billed at standard rate, it wouldn't cost that much; F4 costs 32 cents per instance hour, so F16 would (theoretically) cost 4 times as much, so an F16 instance hour would cost $1.28 per instance hour. We only need 90 seconds at that rate, so 3.2 cents. I think paying 3 cents extra per instance startup is very reasonable, especially if it prevents user-facing cold instance startups. It's entirely doable on a technical level too. Amazon AWS has a similar system where Micro servers can temporarily boost to 2 compute units, then get lowered to their allotted 1 ECU. Linux has the ability built-in: see nice/renice http://en.wikipedia.org/wiki/Nice_(Unix) I'd be interested in hearing if this system is possible within the GAE hosting system. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Re: Startup time exceeded...on F4?!
I did, and used Objectify (Jeff is kinda familiar with that I think :)). A plain Hello World with only registering the entities will get you around the 4-5 sec mark, which is hardly a real application. I have a highly optimized app as a backend for my Android app, and that even takes around the 6-8 seconds mark to start up and it varies too. Add in some third party frameworks, like Jersey for JAXRS and Guice to keep your code sane and you're at the 12 secs. So kool aid or not, Java start up overhead will always be more than it is for python and I think the 5 seconds mentioned is far from typical if you are running a non-trivial app. On Friday, July 20, 2012 6:20:56 AM UTC+2, Brandon Wirtz wrote: Dump PMF use the low level API https://developers.google.com/appengine/docs/java/javadoc/com/google/appengi ne/api/datastore/package-summaryhttps://developers.google.com/appengine/docs/java/javadoc/com/google/appengine/api/datastore/package-summary Either drink the Kool Aid, or quit complaining :-) 5s will be 1.5 -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Re: Startup time exceeded...on F4?!
That's just not true - I have an app which uses no third-party libraries at all, uses no persistence and in fact it uses no GAE services. It simply has one servlet which processes request headers and returns a response. My average start-up time for this app is 3 seconds, when it's running well. The simple fact is that as soon as you use any third-party libraries, or do anything vaguely useful, you're out of that 5 second magic window.

Re: [google-appengine] Re: Startup time exceeded...on F4?!
Sorry, but, please forget about 5 secs 'magic' window. There is no any hard/soft deadline/threshold like that in the current App Engine system. It was just a one example of well behaved apps. Let me rephrase what I meant to say. With app engine, it is always a good practice to keep the loading request faster. The current scheduler works much better with fast loading apps than with slow loading apps. So I always suggest developers fastening the loading request. On the other hand, we understand that Java apps tend to be slow at a level where it is not acceptable for you if there are many user-facing loading requests. For a time being, please use min idle instances settings to reduce the loading requests with slow loading apps. -- Takashi On Jul 20, 2012 5:16 PM, Simon Knott knott.si...@gmail.com wrote: That's just not true - I have an app which uses no third-party libraries at all, uses no persistence and in fact it uses no GAE services.

Hi Chris, Did you see this error at a time when a new instance was starting up? I saw the same thing when I was doing some load testing. The problem seem to present itself when a new instance was added. My theory is that the scheduler routed the requests to ia new instance before it had completely loaded. For whatever reason the instance died taking with it the requests. -Kyle -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Sorry for the inconvenience and thanks for reporting. -- Takashi -- You received this message because you are subscribed to the Google Groups Google App Engine group.

RE: [google-appengine] Re: Startup time exceeded...on F4?!
If you follow the group longer you should know - Brandom lives in GAE unicorn land and all you ever need are proper Edge cache settings. ;) No, I just don't write code using unnecessary frameworks and I do a ton of testing and architecture planning. Most everyoneelse never uses defer or threads or task queues. They don't manage steady state tasks, or profile their imports. It is easy to blame the platform, but if you write crap code it will run like crap. I don't think GAE is perfect. But most the people who complain about its failings don't have the coding skills to be an intern at my shop. I blame Google for not documenting everything well. I blame google for not telling you don't use frameworks they suck. But the number of people who load spring and the gripe that it is slow and are only using 3 things out of it make me want to punch them in the head. The people who don't know how to build APIs so that apps are task specific. Piss me off. Build modular. Dump frame works. Defer often. Be your own scheduler by shaping internal ops. Cache incoming. Cache reads cache writes. Manage threads. Use warmups. This is not rocket science. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

All your pages should have the ability to have an optional ?debug=true Then if you have set that in the url the first line in every one of your functions, and before your imports, should be Timer start and the last thing should be Log Timer -Original Message- From: google-appengine@googlegroups.com [mailto:google- appeng...@googlegroups.com] On Behalf Of Jeff Schnitzer Sent: Friday, July 20, 2012 11:00 AM To: google-appengine@googlegroups.com Subject: Re: [google-appengine] Re: Startup time exceeded...on F4?!

Does anyone with high startup times ( say, 30+ seconds) want to share the results of a code profiler/appstats? What code profiler works on GAE server-side? It's not very helpful to profile in the dev environment since the problem does not manifest there. Appstats is not helpful; my startup is long even with zero service layer calls.

Hi Brandon, The people who don't know how to build APIs so that apps are task specific. Piss me off. Build modular. Dump frame works. Defer often. Be your own scheduler by shaping internal ops. Cache incoming. Cache reads cache writes. Manage threads. Use warmups. This is not rocket science. OT, but how are you cacheing writes in a fault tolerant manner? Task queue? I've been trying to develop a strategy for that. Also, what do you mean by Cache incoming?

Re: [google-appengine] Re: Startup time exceeded...on F4?!
Cache Incoming requests= The thing that I am always accused of. Use Edge Cache to make sure you don't need to serve people who are asking for the same thing. Fault Tolerant writes is about determining how race your race conditions are, and being smart about your writes. Common things I see, people want to increment something so they get count. Which is slow. Then they +1 and write. That is really slow. I use Defer for a lot of writes when I know I wont have a read for a bit of time. Google Bot just did something. Well Frak Google Bot, it's not a real user, delay that write until we have time for it. Defer. You have to look at your write types and determine the priority so you can decide how important it is to be fast, if you 100% need the write to complete, or if you are just doing something hoping people will use it later. Write to a write Cache with the Marshall/pickle, if you need the data broken out as well, do a follow up and read the Serialized data and write the individual bits when you have more time. Do reads in a similar way when ever possible use serialized data.
