[appengine-java] JavaScript implementation enclosed with /*-{ and }-*/ error message when compile the taskengine demo project (included in App Engine Java SDK)

I used a servlet to spit out an upload URL in plain text. If its unsecure, you could just type a get request into the url and it should render a url in a format that you could grab.

[google-appengine] Datastore Reads and Writes Crazy High
i made from significant adjustments after the new pricing as a result of the large, make that HUGE, numbers of reads and writes. I have eliminated most of my indexes but I am still getting these numbers. e.g. I am creating a single entity during a startup operation ... when i look at this entity in GAE launcher it says 170 writes. Ok ... I am writing a single entity that has NO indexes. The entity doesn't have that many fields but it says 170 writes. Also, I assume these are just datastore writes and not memcache writes. Correct? My billing history seems to bear out this numbers, but I am doing 100,000 writes a day which seems wrong by a factor of 100. It would be great to get better breakout of these writes in the datastore statistics or anywhere. I have to get to the bottom of this so I at least know why I am seeing such high numbers. Any explanation would be greatly appreciated. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Datastore Reads and Writes Crazy High
I used the appstats tool to figure out where all my datastore writes were coming from. Super easy to configure, and barely any processing overhead. http://code.google.com/appengine/docs/python/tools/appstats.html http://googleappengine.blogspot.com/2010/03/easy-performance-profiling-with.html The only problem I had with this tool was it made my memory usage grow exponentially for a cron job that my backend was executing. The backend does a lot of work, and this job usually lasts 3 minutes, even though it happens only once every hour. But since this memory explosion was limited to a single type of request, I was able to exclude it from appstats by using appstats_FILTER_LIST in appengine_config.py. Hope this helps.

For Estimated Charges Under New Pricing, my app is showing $40/per day for Writes and $13/day for Reads. $40 worth of writes is 40 million write operations.

[google-appengine] Re: Datastore Read and Writes Statstics
Rishi Thank you for your suggestion. I have been using it. But for a large app, it is a manual way of finding out which table is getting hit most. Also, if tables have few fields with indexed=false, it becomes really hard to figure out the true cost of writes across tables.

As per this doc: http://code.google.com/appengine/kb/postpreviewpricing.html#operations_charged_for There are 3 categories of Datastore operations: Write operations (Entity Put, Entity Delete, Index Write) Each of these operations will cost $0.10 per 100k operations.

[google-appengine] Re: Datastore Read and Writes Statstics
Just to jump in here, I also agree that we could do with an easy way of identifying where costs are coming from. I like appstats, but it gives you a detail level view for one request. Perhaps information like this might be useful for people Entity Name - Total Writes Total Reads Total Small Operations It could also give stats on indexes on this entity. (As an easy way to remind new people that they really need to keep an eye on indexes) J. ps.. I usually caveat my posts with this - I don't have a live app, so don't listen overly to my words.

Re: [google-appengine] Re: Datastore Read and Writes Statstics
I'll take a shot at mapping these. datastore_v3.Put will result in one Entity Put + One Index Writes for each index field that was added (in case of new records), or Two Index Writes for each index field that was modified (an index delete for the old index value and an index write for the new value). datastore_v2.Get is equivalent to Entity Fetch datastore_v3.RunQuery is equivalent to a Query. It seems that app stats was written to reflect on the costs in the old pricing model. It'll be nice it is redesigned to be consistent with the new pricing model. I don't know who supports this tool, but can anyone in the GAE team tell us if there are plans on updating it? Is app stats open source, allowing anyone to take a stab at it?

Re: [google-appengine] I can't point my www Google Apps domain to my Appengine app...
I believe that Google people can make just a little better the Google Apps dashboard... I couldn't see Sites service in my Services tabs but it was running. I googled How to disable google sites and I couldn't do anything because Sites services wasn't in my Services tab. Finally I had to follow this flow: Dashboad - (in the Service Settings block) Add more services - Add Google Sites, and then finally I could see again Google Sites in the Services tab, and remove the www mapping.

[google-appengine] memcache distribution
hi folks,
i'm puzzled by memcache related logs i see and need your advice.
i'm running a java app. i use memcache as a holder of some static variables
accessed and changed by different modules.
i do it, because as far as i understand such changes will apply to all
distributed application instances.
the initialization of the memcache is done within an init() method of a
servlet flagged with load-on-startup.
i have a following piece of code there:
if(CacheManager.getInstance().getCache(static_vars) == null)
{
CacheFactory cacheFactory = CacheManager.getInstance().getCacheFactory();
Cache cache = cacheFactory.createCache(Collections.emptyMap());
CacheManager.getInstance().registerCache(static_vars, cache);
cache.put(var1, 0);
cache.put(var2, 9302);
.
}
now, i'm watching the logs and i see two requests arriving within 2 seconds.
the first one targets an existing instance and everything goes as expected,
but the second one triggers a creation of new servlet instance that loads
the cache. i guess it happens because another application instance is
created. the problem is that i see that in this new instance
CacheManager.getInstance().getCache(static_vars) == null. the new instance
does not recognize that a memcache with this name already exists and
therefore does not use the values that were set there by first instance.
what's my problem here?
thanks in advance.

[google-appengine] newbie: Javadoc on Eclipse
Hi all, I'm new on Google App Engine and relatively new on Eclipse-Indigo (I've been playing around with Android development for several months). I successfully created and ran an online app engine sample project. I'm new to many of the Java classes involved, so I would like to have Javadoc for basically javax and jdo, but is not available in the SDK. I fight for that for hours (Eclipse is big and has many many options) and finally find a way to activate Javadoc on Eclipse, by changing the Javadoc path for servlet-api.jar and jdo2-api-2.3-eb.jar packages on the App Engine SDK node in my project. I've installed glassfish3 to get javadoc for servlet (path: file:/ Users/cristian/glassfish3/glassfish/docs/api/) I couldn't find the javadoc zip file for jdo 2.3, only jdo 2.2 or jdo 3, and find somewhere that location http://db.apache.org/jdo/api23/apidocs/, that works fine. Everything seems to work fine but, after each Eclipse restart, this 2 paths are forgotten and replaced by the default SDK paths. Please! someone can brought me some light on that? Which is the correct way to enable Javadoc for the packages that don't have documentation in the SDK? Thanks a lot!!

[google-appengine] chat application design help app engine

I did similar app before where i assigned unique id to each user.Once the user enter the app his ID will be inserted into static synchronized LinkedHashSet(which acts like global datastore for app).Similarly second user enters synchronized LinkedHashSet,If he finds the ID other than his ID then they are connected.The Second user removes their ID's from LinkedHashSet and Inserts them into Mysql DataBase as pairs.Note that access to LinkedHashSet is synchronized.

[google-appengine] calling out the app engine team on ssl for custom domains
Hi (I apologize, it's a long one). I'm calling out the app engine team on how they've handled issue 792http://code.google.com/p/googleappengine/issues/detail?id=792colspec=ID%20Type%20Component%20Status%20Stars%20Summary%20Language%20Priority%20Owner%20Log - ssl/https support on google apps domains, and would like a straightforward answer to the current status of this issue. Before I get into how the team has dealt with the issue and my problem with it, I'd like to make a few observations: 1. The engineers on the GAE team have known about the lack of SNI on IE in XP for quite some time (see comment #48http://code.google.com/p/googleappengine/issues/detail?id=792#c48 - quoting an IRC session). We can safely regard August 2009 as a point of time at which GAE engineers knew about this problem. 2. The issue was market as Started in October 2010. The GAE team and/or it's decision makers have clearly chosen to work on this issue. This is non-trivial given the success of GAE which, as usual, has lead to a queue of dev tasks far larger than the capacity of the team. In other words, this issue is decidedly important enough to work on that dev resources are prioritized to work on it. 3. In the last two Google I/O events, the issue of SSL on google apps / custom domains has been prominently displayed as a feature which will be available 'soon', whether as part of GAE for Business (available by EOY 2010) or as a feature that's on deck for general availability. 4. Despite the issue of SNI and IE/XP, there appear to be a handful of possible solutions to overcome the limitations it presents. More on this later. 5. Other features which have been taken on by the team and were expected to take a relatively long time to bring to fruition have been declared as such. For example, if we look at the Full-Text Search issue, it was marked as Started back in October 2009, but with the following text: I'm marking this issue as Started but I want to set expectations appropriately: This is a major undertaking and this will not happen soon, even by the most generous definition of soon. Given these observations - it is understandable and acceptable that there are factors beyond the control of the team; namely that the lack of support for SNI in IE on Windows XP presents a technical obstacle. On the other hand, the recurring assurances that this issue is being worked on, and in some cases promised to land about a year ago, leads one to believe that regardless of the SNI problem the feature will be generally available in the near term future. Case in point: SSL access on custom domains has been on the roadmaphttp://code.google.com/appengine/docs/roadmap.html since May 2010, updated around the time of I/O 2010. Given the heading ..Most of these features here are intended to be launched within the following six months. .. it should come as no surprise that a sizable number of developers are quite irate over the fact that we are now well into September 2011 and yet no sign of SSL for custom domains, for better or for worse. At no less than a keynote speech of I/O 2010http://www.youtube.com/watch?v=a46hJYtsP-8feature=player_embedded, given in front of thousands of developers, Kevin Gibbs says in regards to App Engine for Business (@113:12): ..That means we're putting our money where our mouth is when it comes to the reliability of your business. And finally, it also comes with two additional key features that we had heard almost every enterprise needs: SSL for your company's domain and SQL databases. That's right. You heard me right. On the other hand, a full year later, at a fireside chat from I/O 2011http://www.youtube.com/watch?v=_nN-G4018b0 the SSL issue comes up a few times and at some point Peter Mckenzie, who claims responsibility for SSL, says (@26:35): We are actively working on it and making good progress. We can't give a date, but it's certainly high priority. To be honest, we would have liked to have launched it by now, but it's certainly foremost in my thoughts, and in the thoughts of several others of my team. .. immediately followed by a moment of candor by Brett Slatkin, who jokingly suggests we get everyone to install a browser with SNI and/or move to IPv6. I'm calling out the app engine over what has happened over the course of 2-3 years on this issue. First, the issue is accepted in 2009 and marked as 'started', despite the known SNI problem. Next, in 2010 it's added to the roadmap, announced in a keynote and given an approximate ETA of EOY 2010. Yet a year later, all of a sudden they don't have a date and are throwing around remarks about how they would have liked to launch it by now. The duplicitous and shady behavior on the issue of SSL on custom domains is, in googley terms, a form of evil. On a personal note: You'll have to take my word for it that I had attended I/O 2011 and brought up the issue at App Engine office hours before the

RE: [google-appengine] calling out the app engine team on ssl for custom domains
Amir, While I can certainly relate that a Lack Of SSL is a severe limitation of GAE, I also (not being a Google Employee) can say it is likely not GAE's fault. Google as a whole likely, but I very much suspect that because SSL works on appspot.com domains. When working in a large company often you have to deal with the relationships between your group and other groups. If a feature requires that the infrastructure team, or the apps for domains team, or the Google Edge Cache team make a change, or all 3 make a change, GAE team is limited in how fast they push an item through. Often other groups have minimal incentive to add a feature that doesn't impact their performance metrics. If it is in fact a GAE issue, consider this. Right now you have the ability to resolve this issue: Set up a Squid/Proxy somewhere at Secure.YourDomain.com that proxies requests to https://YourApp.Appspot.com In 2014 XP will be End Of Lifed and the issue will be quick to resolve. As IPv6 approaches IP's will not have significant cost and the issue will be quick to resolve. From a business standpoint, This is a New Feature that attracts new clients. SQL support was something that existing customers were already solving through other solutions, or were fighting through the SQL to GQL conversion issues of their code. CPU Cycles that were being sent to SQL running on Amazon via HTTP requests and other methods were all CPU cycles that GAE was losing, AND giving up market share to competitors. If you want this feature to come faster, use a Squid, implement it yourself, and make sure every time someone else asks about it you point out I had to solve this issue using a Squid Hosted at Amazon. It would be nice if I only had to pay one Cloud Provider so that the guys on the GAE team aren't attacked for not implementing it, and are given ammo to go to other teams, their executives, and whoever else and say this is costing us money, and making us look like schmucks -Brandon Brandon Wirtz BlackWaterOps: President / Lead Mercenary Description: http://www.linkedin.com/img/signature/bg_slate_385x42.jpg Work: 510-992-6548 Toll Free: 866-400-4536 IM: drak...@gmail.com (Google Talk) Skype: drakegreene http://www.blackwaterops.com/ BlackWater Ops From: google-appengine@googlegroups.com [mailto:google-appengine@googlegroups.com] On Behalf Of Amir More Sent: Thursday, September 22, 2011 10:41 AM To: google-appengine@googlegroups.com Subject: [google-appengine] calling out the app engine team on ssl for custom domains Hi (I apologize, it's a long one). I'm calling out the app engine team on how they've handled issue 792 http://code.google.com/p/googleappengine/issues/detail?id=792colspec=ID%20 Type%20Component%20Status%20Stars%20Summary%20Language%20Priority%20Owner%20 Log - ssl/https support on google apps domains, and would like a straightforward answer to the current status of this issue. Before I get into how the team has dealt with the issue and my problem with it, I'd like to make a few observations: 1. The engineers on the GAE team have known about the lack of SNI on IE in XP for quite some time (see comment #48 http://code.google.com/p/googleappengine/issues/detail?id=792#c48 - quoting an IRC session). We can safely regard August 2009 as a point of time at which GAE engineers knew about this problem. 2. The issue was market as Started in October 2010. The GAE team and/or it's decision makers have clearly chosen to work on this issue. This is non-trivial given the success of GAE which, as usual, has lead to a queue of dev tasks far larger than the capacity of the team. In other words, this issue is decidedly important enough to work on that dev resources are prioritized to work on it. 3. In the last two Google I/O events, the issue of SSL on google apps / custom domains has been prominently displayed as a feature which will be available 'soon', whether as part of GAE for Business (available by EOY 2010) or as a feature that's on deck for general availability. 4. Despite the issue of SNI and IE/XP, there appear to be a handful of possible solutions to overcome the limitations it presents. More on this later. 5. Other features which have been taken on by the team and were expected to take a relatively long time to bring to fruition have been declared as such. For example, if we look at the Full-Text Search issue, it was marked as Started back in October 2009, but with the following text: I'm marking this issue as Started but I want to set expectations appropriately: This is a major undertaking and this will not happen soon, even by the most generous definition of soon. Given these observations - it is understandable and acceptable that there are factors beyond the control of the team; namely that the lack of support for SNI in IE on Windows XP presents a technical obstacle. On the other hand, the recurring assurances that this issue
[google-appengine] How to throttle or batch transactional updates to an entity group
Hi there, I'm developing an application that requires me to create lots of child entities within the same entity group transactionally. The tasks being generated to do this come in unpredictable bursts - sometimes 100/s for an entity group. This is clearly exceeding the 1/s limit for transaction contention and causing some real problems for my poor application. I need a way to either batch the required updates for each entity group so I can run through them serially or otherwise schedule each update to run on a 1/s basis. The ideas I've come up with so far: 1. Use some kind of memcache'd timestamp or counter to schedule or throttle the updates. My question is how to do this in a way that will work with 100's of tasks hungrily looking for their time slot? Should I do a CAS for when the last task was scheduled (would this even work with the contention we're talking about?) or can I use an atomic operation like incr() somehow? 2. Store the work items somewhere and then at some later time query for the work items for an entity group and create the children in serial. I'd like to avoid this, if possible, as it creates many other headaches. My application is already using the taskqueue to great effect. This really seems like a queue problem - if only there was some kind of dynamic subqueue where I could add tasks with a 'namespace' of the entity group. Then entity groups could run in parallel, but the entity group items would still be in serial. Does something like that exist? Any suggestions or experiences on how I can work around this would be appreciated.

Definitely checkout Brett Slatkin's Building high-throughput data pipelines with Google App Engine http://www.google.com/events/io/2010/sessions/high-throughput-data-pipelines-appengine.html I/O Session which should give you a fundamental understanding of the caveats involved with batch writing.

Re: [google-appengine] calling out the app engine team on ssl for custom domains
Hi Brandon, Regarding your resolution of setting up a squid/proxy that forwards requests to https://*.appspot.com somewhere: Having all your traffic go through a single server on AWS or other VPS to proxy requests for google app engine is equivalent to buying a top of the line super-car, ripping out it's four-digit horse power engine and strapping it to a moped with the goal of using said turbo-charged moped for a road trip from new york to california, all because the super-car is too wide for some of the roads you might encounter. It might work but you're doing it wrong. Let's try to go with the flow: I'll see your proxy/squid set up somewhere and raise you a multinational dns provider with name servers on most continents with geolocation rules to forward dns requests to the CNAME of a multi-zone load balancer at the nearest AWS region out of 5 worldwide; each region's ELB configured to forward to auto-scaling health-checked linux instances balanced across all availability zones, each instance running a modified linux kernel optimized for the sole purpose of being a web proxy, running either varnish or nginx as a front end, using a SPDY library for SSL requests to app engine (yeah, the app engine front end has SPDY - GAE team didn't even know about it for a while). It would be best to have the AWS ELB use SSL with SPDY to talk to the instances but we'll let that slide. Yet, still, this solution is sub par considering: 1. There's hardly any point to serving static files from GAE, might as well serve them from your proxy. Yay, more locations to push to :) Or you could have your proxy be a literal cache and time out files but then you'd have to either push a cache flush or use cache busters for your content. IMO both reek of an equally vile stench. 2. It's likely the Channel API won't work with all those middle men. If the GAE team starts using websockets (or regular tcp/ip sockets while we're at it) we'd be back to the drawing board. Also various other APIs might be negatively affected or require some tinkering (blobstore upload, XMPP and task queue API) 3. Consistently added latency in the best case - you have the added latency of initiating an SSL handshake with the proxy. Given a solution with a load balancer you'd have two handshakes, and depending on how they're set up either one or both of them will be full SSL handshakes (not just TCP handshakes) 4. Additional highly varying latency in the worst case - what happens when the GAE or production teams move the instances serving GAE requests to another data center? Your users would see a sudden jump in latency since the proxy they're working with takes longer to reach the GAE domains/ips it's been working with. It'll take a while for new geolocation rules at the dns level meant to counter the effect to kick in due to dns caching. 5. It's expensive. The cheapest single server solution is more expensive than the GAE $9/app/month under the new pricing model. The full-blown AWS solution is somewhere around $1k a month. Not including the labor and maintenance required for the custom linux image. There are probably more issues but those are the best I could think of off the top of my head. I think there is no reason to believe that internal politics at google are holding this issue back. Also I can't find a reason to believe that google is an organization set up such that the GAE team and/or their product/project managers need to give financial incentives to other teams just to get a major feature out the door. I'm not saying there aren't internal politics because there probably are. I'm just saying that a feature of this type seems like something that, at worst, would be arbitrated quickly by a manager high enough on the corporate ladder to see the detrimental effect of not finishing this feature a full year after it was announced at a major company event. Regarding 2014 - I agree.. in that MS and their products will be synonymous with myspace by then to developers. But you can't deny the size of MS and their existing install base. EOL for XP doesn't necessarily mean that bureaucratic organizations like government offices will have upgraded by 2014. IPv6.. the jury's still out on that one. The question remains - are we waiting for 2014 or whichever decade will bring IPv6 / end of IE on XP or is there something in the works? I don't take issue with which decision the GAE team made, but with the fact that they're zigzagging on the availability of the feature.

Re: [google-appengine] What happens to URLFetch Async Call that is left alone?
The SDK will automatically create a RPC object for async function, or you can create it by yourself. Before the end of your response, the RPC object will block the respond and wait until it's done, and no callback will be called. However, it looks like the local dev server just ignores it. -- keakon My blog(Chinese): www.keakon.net Blog source code: https://bitbucket.org/keakon/doodle/ On Fri, Sep 23, 2011 at 8:17 AM, Albert albertpa...@gmail.com wrote: Suppose I call URLFetch Async, and then I return a response to the user without calling get_result(). 1.

RE: [google-appengine] calling out the app engine team on ssl for custom domains
I disagree. I would bet money that Putting a Squid in front of your app would make it faster. Page Level Caching and the ability to put your Image assets in cache are going to make things faster. Also I didn't say single there are plenty of solutions that would do PLC from multiple locations. Your budget constraint is a limitation. Not to sound cold, but you knew going in to GAE that HTTPS wasn't supported, and would have to use an external solution work. As such it is hard for me really feel that your complaint about having to use an external solution is founded. GAE zigzags, I chalk up to Politics like I said. I'm sure all the GAE guys know they want HTTPS to work, and I'm sure that they feel silly that it is a feature that doesn't work.

Let's try to go with the flow: I'll see your proxy/squid set up somewhere and raise you a multinational dns provider with name servers on most continents with geolocation rules to forward dns requests to the CNAME of a multi-zone load balancer at the nearest AWS region out of 5 worldwide; each region's ELB configured to forward to auto-scaling health-checked linux instances balanced across all availability zones, each instance running a modified linux kernel optimized for the sole purpose of being a web proxy, running either varnish or nginx as a front end, using a SPDY library for SSL requests to app engine (yeah, the app engine front end has SPDY - GAE team didn't even know about it for a while). It would be best to have the AWS ELB use SSL with SPDY to talk to the instances but we'll let that slide. Yet, still, this solution is sub par considering: 1. There's hardly any point to serving static files from GAE, might as well serve them from your proxy. Yay, more locations to push to :) Or you could have your proxy be a literal cache and time out files but then you'd have to either push a cache flush or use cache busters for your content. IMO both reek of an equally vile stench. 2. It's likely the Channel API won't work with all those middle men. If the GAE team starts using websockets (or regular tcp/ip sockets while we're at it) we'd be back to the drawing board. Also various other APIs might be negatively affected or require some tinkering (blobstore upload, XMPP and task queue API) 3. Consistently added latency in the best case - you have the added latency of initiating an SSL handshake with the proxy. Given a solution with a load balancer you'd have two handshakes, and depending on how they're set up either one or both of them will be full SSL handshakes (not just TCP handshakes) 4. Additional highly varying latency in the worst case - what happens when the GAE or production teams move the instances serving GAE requests to another data center? Your users would see a sudden jump in latency since the proxy they're working with takes longer to reach the GAE domains/ips it's been working with. It'll take a while for new geolocation rules at the dns level meant to counter the effect to kick in due to dns caching. 5. It's expensive. The cheapest single server solution is more expensive than the GAE $9/app/month under the new pricing model. The full-blown AWS solution is somewhere around $1k a month. Not including the labor and maintenance required for the custom linux image. There are probably more issues but those are the best I could think of off the top of my head. I think there is no reason to believe that internal politics at google are holding this issue back. Also I can't find a reason to believe that google is an organization set up such that the GAE team and/or their product/project managers need to give financial incentives to other teams just to get a major feature out the door. I'm not saying there aren't internal politics because there probably are. I'm just saying that a feature of this type seems like something that, at worst, would be arbitrated quickly by a manager high enough on the corporate ladder to see the detrimental effect of not finishing this feature a full year after it was announced at a major company event. Regarding 2014 - I agree..
Re: [google-appengine] What happens to URLFetch Async Call that is left alone?
What happens when you start an RPC, but not wait for it to finish is not really defined. As you have may have noticed, it also works differently in production and in the dev appserver. Also note that since it is not defined, the behaviour may change at anytime. I would suggest that you should also wait for an rpc call to finish before returning from your handler. This will also allow you to determine if the rpc call succeeded or not.

Thanks! How about in the Production environment? What's the behavior there?

Hi Greg, So what Nick said here was just current implement, and it's not safe to rely on it? https://groups.google.com/group/google-appengine/browse_thread/thread/cbcf2868f3eace1b/6920032edd68f3a2 On Sep 23, 12:45 pm, Greg Darke (Google) darke+goo...@google.com wrote: It is undefined, and thus you should not do it.
