[google-appengine] Possible workaround for datastore timeouts
I've added issue 982: http://code.google.com/p/googleappengine/issues/detail?id=982 as an issue to include a possible workaround for the datastore timeouts. Here's the text of the issue: From what I can tell, it's not a case of if you're going to get datastore timeouts on puts, but when. My original thought was for input actions on my application to use javascript to do the action, catching timeouts and trying again. On a scripted input I have for my site this has worked extremely well for making sure the data gets into my site. However, when I started taking into account all the writes that happen through the operation of my site, I realized that this methodology makes more sense to integrate at a lower level than the front end. When I have time, after I fix a few other things with my application, I intend to look at creating a new Model for my site to use which will handle this at the put() level. Something to the effect of: MAX_PUT_RETRIES = 3 count = 0 while count MAX_PUT_RETRIES: ''' try to put the data. if the put fails due to a datastore timeout, increase the count and try to put again. Ideally throw another exception if it hits MAX_PUT_RETRIES without adding the data.''' If something like this could be added to GAE directly, I think it would help a lot of people. Though of course the extra CPU usage caused by these timeouts would still be an issue. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

That means that there cannot be a change in the models definitions between versions. v2 of an app is presumably for testing, so the data there need not be preserved. If the data in v1 needs to be preserved after the switch to v2 one can always dump and restore the db.

I don't think splitting the datastore per app version is such a good idea. What if the data is added to v1 of the datastore while you are testing v2? At the same time you are modifying your v2 datastore (otherwise, you wouldn't need different datastores per app version). You would have to merge somehow the data from v1 to v2 before switching to v2. On Jan 12, 1:46 pm, Roman roman.budzianow...@gmail.com wrote: It appears that different versions of an app share the db.

Yes, Marzia is part of the app engine team. I'm hosed. Cesium, What algorithm are you trying to implement that requires synchronized clocks? To my knowledge it's a pretty well-known best-practice to never rely on clocks being the same across a distributed system. Some algorithms can take advantage of closely correlated clocks, but I believe they never need anything better than the guarantees of NTP (http://en.wikipedia.org/wiki/Network_Time_Protocol), which is essentially what App Engine provides. If you need a guaranteed ordering of time, there are a few ways to do this. One simple way is to use a set of incrementing sequence numbers in the Datastore. Every time an event happens, you transactionally increment the sequence number and write the event record to the Datastore. Then it doesn't matter what the timestamp is on the record, the events will always be ordered by the absolute time that they came in. This has some scalability issues (because you essentially have a global counter). But if you can partition your data reasonably, you could probably optimize throughput quite a bit. Another way is to use a technique like Andy Freeman mentioned. Every time you store an event record, you also write the new maximum timestamp to the Datastore (or preferably memcache). To determine that initial timestamp, you can query for the maximum timestamp record with the latest timestamp. This will likely result in events that happen at exactly the same time, though. If you need to guarantee that you always have ascending timestamps that are never the same, then you'll need to use a sequence-number-like solution as I described before. To make this scale correctly, you would want to partition your sequence number counters based on the event incidence time. That way if you got two events at exactly t=10.123 seconds, you could do two transactional updates and end up with one event at t=10.1230 and another at t=10.1231. The throughput of this solution will depend on the resolution of your clock. I hope that all makes sense. -Brett --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: user login URLs in html/javascript
Geoffrey, It is not my desire to hardcode the urls, but I don't know how not to; my programming skills are limited. Or maybe I have not understood the suggests given here by you folks about how to do it in a way that is not hardcoded. The path a user takes in my application depends on whether s/he is logged in or not, and if logged in, whether s/he goes to a map s/he created or not. If a person has a google account, s/he may not want to use the app as if s/he does, because s/he will see different results from her/his users. On top of that, the users only interface with the app is via html pages, not python pages, so I don't know how to put links that change or appear and disappear according to user responses, into an html page. If I were to wait to ask the user about his/her logging preference at key times while the python program is in control, that would be ok, but I don't know how to do that in a way that keeps the html page visible in the background the way a javascript confirm dialog produces a little popup dialog window; that's my first choice, but I don't know how. My inclination is more toward developing another related app now, but I would be pleased to learn how to code a softcoded link if you or others can explain it to me. Thanks very much for expressing your question. On Jan 12, 12:11 pm, Geoffrey Spear geoffsp...@gmail.com wrote: You still almost certainly want your app to dynamically generate the links at runtime; I don't believe there's any guarantee that these hardcoded links will keep working if Google changes the login system, and the users API specifically includes functions that return the correct URLs so you don't have to hardcode them. I'm not sure why you think hardcoding in the link rather than generating it at runtime has anything to do with the ability to not require people to click it. It still just shows up as a link on a webpage. Brian in Atlanta --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: Global Time Synchronisation Guarantees
What algorithm are you trying to implement that requires synchronized clocks? To my knowledge it's a pretty well-known best-practice to never rely on clocks being the same across a distributed system. Some algorithms can take advantage of closely correlated clocks, but I believe they never need anything better than the guarantees of NTP (http://en.wikipedia.org/wiki/Network_Time_Protocol), which is essentially what App Engine provides. My application requires a time stamp from GAE that differs from UTC by no more than 1s. (I'll worry about latencies.) Imagine for example, a global network of sensors that measure geophysical data. The usefulness of the data is degraded if there is a large uncertainty surrounding the sample epoch (timestamp). I'm confused. Marzia in this thread has already said they dont offer any guarantees. but you say: ...the guarantees of NTP (http://en.wikipedia.org/wiki/Network_Time_Protocol), which is essentially what App Engine provides. NTP is pretty good. Better than 1 second. That would suffice. In summary, my understanding is that GAE does not offer any guarantees about the uncertainty of their server clocks, but they do run NTP. So, when the server clocks are tightly phase-locked to UTC via NTP, all is well. But when they are not sync'd, we'd have no indication that a given timestamp is far from UTC ( 1s). There are no guarantees that they'd bypass a server that greatly differed from UTC. Is that the state of things?

[google-appengine] Re: Can not delete entity using Data Viewer and a GQL query.
Hi, If you reply with your app id I can look in to it directly. If you can find the data in the dataviewer, however, you can get the key string (from the data's URL) and call db.delete() directly on that key in your application (if, for instance, you included something like shell with your application so you could run interactive commands). -Marzia On Sun, Jan 11, 2009 at 1:33 PM, murexconsult...@googlemail.com robin_ow...@hedge-row.co.uk wrote: There was a bug in my app and some bad data got into the Datastore. So I want to delete some data. The models have a number of items so rather than paging through them all 20 at a time to find it I ran the GQL query: SELECT * FROM UserUpdates WHERE windAngle=328 This returns one row as expected. I then click on the tickbox beside it and click on Delete. I then get a dialog box asking if I am sure to which I say yes. I then get the error displayed in a red box at the top saying The URL to forward to once the request is fulfilled - Yes the error is a partial sentence and makes no sense. The item is NOT deleted. This is happening to all 4 of my models. However 2 of them only have a few hundred entries, so I was able to page through, find the item and delete it. When I paged through, the deleting was successful. I think that there must be a bug in the data viewer when removing data found using a gql query.

[google-appengine] Re: Update just one (or few) files
Version control becomes essential for maintaining app engine apps. With Subversion, for instance, you can tag your repository whenever you deploy, then keep working along the trunk. If you want to make a change to the current production app, check out the tag, make the change and deploy again. Make sure to merge the change into the trunk though, either manually or with the Subversion merge tools. I haven't been doing this very well myself yet, but do run into this issue a lot, so will be starting to more. Since App Engine does have the awesome versioning, it would be handy to also sync up the App Engine version label with the tag you use in your source control.

[google-appengine] Re: user login URLs in html/javascript
Do you use (Django) templates? If not start using them, separate the function (code) from the presentation (html) Read the GAE example http://code.google.com/appengine/docs/gettingstarted/templates.html There they show you how to use the users.create_logout_url() users.create_login_url() methods in templates, read the Django doc about templates for version 0.96 for more things you can do. 2009/1/12 thebrianschott schott.br...@gmail.com: Geoffrey, It is not my desire to hardcode the urls, but I don't know how not to; my programming skills are limited. Or maybe I have not understood the suggests given here by you folks about how to do it in a way that is not hardcoded. The path a user takes in my application depends on whether s/he is logged in or not, and if logged in, whether s/he goes to a map s/he created or not. If a person has a google account, s/he may not want to use the app as if s/he does, because s/he will see different results from her/his users. On top of that, the users only interface with the app is via html pages, not python pages, so I don't know how to put links that change or appear and disappear according to user responses, into an html page. If I were to wait to ask the user about his/her logging preference at key times while the python program is in control, that would be ok, but I don't know how to do that in a way that keeps the html page visible in the background the way a javascript confirm dialog produces a little popup dialog window; that's my first choice, but I don't know how. My inclination is more toward developing another related app now, but I would be pleased to learn how to code a softcoded link if you or others can explain it to me. Thanks very much for expressing your question. On Jan 12, 12:11 pm, Geoffrey Spear geoffsp...@gmail.com wrote: You still almost certainly want your app to dynamically generate the links at runtime; I don't believe there's any guarantee that these hardcoded links will keep working if Google changes the login system, and the users API specifically includes functions that return the correct URLs so you don't have to hardcode them. I'm not sure why you think hardcoding in the link rather than generating it at runtime has anything to do with the ability to not require people to click it. It still just shows up as a link on a webpage. Brian in Atlanta --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: Global Time Synchronisation Guarantees
You have no knowledge when your request is executed on the server. Launching a new interpreter takes time, the server is busy processing other requests. If the time of the data is important you should take a time measurement at the sensor and send it as part of the request 2009/1/12 Cesium cesiumpic...@gmail.com: My application requires a time stamp from GAE that differs from UTC by no more than 1s. (I'll worry about latencies.) Imagine for example, a global network of sensors that measure geophysical data. The usefulness of the data is degraded if there is a large uncertainty surrounding the sample epoch (timestamp). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.
