Today, my app has seen 2 timeout errors at 3:10 pm according to the log. Each one was 30 seconds apart. One was a Get and the other a Put. Each on totally different classes that are not connected in any way. On Apr 17, 4:15 pm, Brandon Thomson gra...@gmail.com wrote: Google will not really acknowledge this as a problem or defect but neither do they provide a lot of options for workaround. My experience is that Timeouts do occur on about 0.5% of puts regardless of size of entity. These are root entities. It is not caused by write contention from multiple requests on the entity. A handler only called by periodic cron job will experience it. For one week in March when they were playing around with the architecture Timeouts went from about 0.5% of all puts to about 5%. Since it has been not as bad.

[google-appengine] Re: SMS via Email
I agree. I'm using a gateway as well. I wouldn't recommend the email method. Jim, I am curious on who you are using for .03 a text.

It used to be you could look up with the area code and exchange and determine which carrier issued the number and then know which email gateway to use. Well, actually you can still do that but with cellphone number portability, you don't know which carrier currently services the number, you just know which carrier issued the number. So you wind up having to ask your customer to provide their phone number and specify which carrier they use. I recently did an integration to a SMS gateway. They have a variety of APIs including HTTPS, XML, SOAP, etc. They have a callback mechanism so your app gets status updates on the delivery status of each message. Only draw back is it cost $0.03 per message. There may be cheaper ones out there, I'm not sure as I got tired of looking around and three cents was reasonable for my usage. It just depends on if you're willing to live with the limitations, then the email approach is fine. If you need something cleaner and more reliable, then I suggest subscribing to a sms gateway service.

[google-appengine] Re: Noobie with google app engine. Need some help.
Take a look at the documentation for uploading an app here http://code.google.com/appengine/docs/python/tools/uploadinganapp.html However, I think you are using the app engine patch and may need this instead. http://code.google.com/p/app-engine-patch/wiki/GettingStarted I don't use the path and don't have experience setting it up, but this should help.

I only know html,css, php, python. I never heavily used python so I am rusty with it. I only had experience with using apache and mysql. I am new to google application and have been doing research on it. I found it uses a different database system. I already made the website for the company now I need to upload it to google apps and also make modifications in python scripts to add some server sided functionalities. So far it's been about 4 weeks. My ceo is really upset. He never gave a deadline but he wanted it to be done as soon as possible. He is now breathing down my neck. I am stressed out . So to make matters worst I need to learn how google apps engine works and how I can use it in a quick manner. The ceo has been talking to the previous VP of technology. He is the one the made the website. I just added onto it. So He gave me the original website files meaningthe python and the folder. He told me I have to use manage.py to update or test run the app meaning the website. Currently I tried the manage.py which was inthe apps folder and this folder was in googles engine folder. I been getting a error saying can't find SDK. So I moved the manage.py to googles app engine folder and it worked. Yet when I tried updating It showed 96 files trying to be updated to googles server then I got a limit error. I e-mailed the ceo which e-mailed the previous programmer. He told me that the manage.py needs to stay in the app folder not the google engine folder. He told me I need to use PATH=$PATH:/path/to/google_ I don't understand what he ment by that. I am guessing I had to add that to manage.py? Not sure I might e-mail them back. So currently I need to just update a website which is a web app on google app engine. So I need to learn the structure of how to use google apps engine. I need a tutorial that would explain me the structure from a php/ mysql apache user point of view. Meaning I need a explanation what's used with php and what is used in google that relates to php in the server sided way. I thiink that would be the quickest way i can learn this else I might get fired. I do really need to keep this job. I told the ceo that I am not experienced in google nor python. I did some coding in python but it wasn't that much to make any app. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

Hi I get a message on my script that my average cpu is over 1300. However, when I review the details I can't see any cpu time used or any High CPU requests used. Second of all my script is not all that complicated and only makes 8 datastore api calls per request.

[google-appengine] Re: Should I use App Engine Patch
thanks for the advice all. On Jan 4, 12:30 pm, Bobby bobbysoa...@gmail.com wrote: I was also undecided on whether to go with Django on top of the GAE but ended up going for it using the AppEngine Patch and i'm glad i did. Yesterday i needed to setup feeds and Django took care of everything in literally a couple of lines - it just keeps on giving. Also, the beauty of self-contained apps (so easy to do in Django) is something you won't be able to go without after having done a few. There are some types of sites where i wouldn't use Django but these are mostly specialized apps (more of web-based applications than content-driven sites). I highly recommend you look into both the AppEngine Django Helper and the AppEngine Patch (create some simple Django apps, go through the documentation for the AppEngine and Django side-by-side), above all it's important you get a feel for what's out there so you can make the best decisions, you'll learn alot about best practices - also see the video Waldemar linked to.

Actually, Google did release django-helper, but we (app-engine-patch) disagreed about unnecessarily introducing a new model class for Django users. More interestingly, I discussed that with Matt Brown (maintains django-helper) and he agreed with our decision. It would've just been difficult to remove the custom model class, again. and i personally think , webapp is sufficient for pretty large project , afterall * no matter how much django do for you , * atlast for sufficiently large project we endup with our own library-or-framework.

[google-appengine] Should I use App Engine Patch
I'm not sure of the benefits of using the Patch. I have been able to build two good sized apps (1000+ lines of code each) using the App Engine defaults. I know my code is not best practice yet, so I'm looking to learn more and make my next app better. While I like how the models are setup, the process of creating and maintaining an app seems complicated. Can you tell me what I would gain from using the Patch.
