[google-appengine] Re: Want better GAE downtime tracking / visibility??
HI I couldn't agree more. Absolutely the single biggest issue I see with app engine is not feature set, performance or availability but the lack of communication when things go wrong, and if you are in a appengine dead-zone trying to get any form acknowledgement that there is a problem. I have lost count of the number of posts I have made along these lines. (as you will see about half way down this thread http://groups.google.com.au/group/google-appengine/browse_thread/thread/ff1a8d0051b0bc64/d78e8ca4482c5ab2?q=#d78e8ca4482c5ab2 and http://groups.google.com.au/group/google-appengine/browse_thread/thread/23e988d494144242/8ff964f7ffcc0b37?q=#8ff964f7ffcc0b37) Once it took over a week to get any form of acknowledgement.

[google-appengine] Annoyed with GAE System Status: Investigation Complete - Issue Resolved?
Star this: http://code.google.com/p/googleappengine/issues/detail?id=3726 The App Engine System Status frequently shows the following message: --- Investigation Complete - Issue Resolved We have determined that this spike did not affect the performance or uptime of applications. If you feel we have incorrectly diagnosed this issue please inform us by posting in our developer forum. --- We appreciate that this accurately conveys the diagnostics output on the back end, and that the tools that generate these are (presumably) largely automated, but the wording of this message really needs to be improved. The text is simply not appropriate at times when the key metric indicators are going red and apps are failing. The "feature" request asks that Google change the wording of this message. By clicking on and "starring" the issue we can help Google quantify the our collective frustration with this, and make it easier to prioritize. (There is a larger issue here relating to what triggers this message in the first place, and if it is appropriate to display this when the indicators are going red and apps are failing...)

Star this: http://code.google.com/p/googleappengine/issues/detail?id=3725 Like many of you, we rely on the GAE, as do our customers. We feel that the GAE has an excellent overall uptime, and are in awe of the people who made GAE happen and keep it running on a daily basis. Some downtime is inevitable, and it's not important to us that GAE experiences occasional downtime. What's important is how it is handled, and the communications around this (we feel) could use improvement. The "feature" request asks that Google provide regular and structured updates on outage handling.

As of 10:01pm (PDT, log msg time), my app is still generating a lot of deadline exceeded error. It happens like every 30min (not able to backtrace too far since the log viewer is broken for me after paging) and when it happens, all db put requests in that minute or two prompt the error.

[google-appengine] Re: Request was aborted after waiting too long
What is the average response time from your app for normal requests? If it is > 1000 msec, the GAE appears to become reluctant to start up new VM's for you, the result being that requests queue up, and after some period in the queue, are deemed "stale" and get kicked with this error. Want to test this assumption? Flood your app with no-op requests that don't do anything (use a URL no one would normally use, and just return from the GET call). If you have enough of these (simplest no- op returns in < 50 msec), the math shifts your average to below 1000 msec, and presto. It's a stupid solution to what's either an outright bug or an overzealous resource manager behind GAE, but it sure seems to cure these.

[google-appengine] High-Performance Image Serving Cache-Control
Hi everybody, I would like to allow browser caching of images served from get_serving_url(). I've had success using get_serving_url() for generating images and thumbnails but the Cache-Control is set to "no- cache" and the expiration dates are in the past (I've only implemented this functionality on the development server, I have not tried to deploy yet). Is there any way of setting the Cache-Control? I can't seem to find any info in the documentation or with a general search, other than a reference to High-Performance Image Serving: "It also handles setting proper Cache-Control headers so you don't have to worry about that."

Someone in Google has tried turning it on and off again. Things are really flying now. I would just ask Google to stop with the standard "We have determined that this spike did not affect the performance or uptime of applications." Please change that default message to something a little more vague and less insulting. Thanks!

I'm getting errors today too. No changes in my app for months. My errors are related to using sharded counters (using the well document shd_counter,py code). .

[google-appengine] Re: Increased CPU Time/Request after yesterdays maintenance?
Java 12% of all requests (several thousand) have resulted in an error. Not sure of the specific cause but most errors are 500 errors being returned. My biggest moan would have to be the huge increase in cpu time used which is being caused by PUT requests made to the datastore taking AGES to complete. Yesterday my resource would use approximately 300ms in total, today a single PUT (of which I have three) is taking anywhere between 300ms and 400ms - it's just not acceptable.

Now the status site is just returning a blank page and the rate of 500 errors has gone up significantly. I can't believe that downtime notice thinks this issue is over. My app is barely usable.

Can you guys list how often you guys see these? Here's some information that'd be helpful for us: - What % of your requests return "Request was aborted"? Is it happening at specific times? Java or Python? - App ID There was a latency spike around 4am ( http://groups.google.com/group/google-appengine-downtime-notify/browse_thread/thread/7a9705743782ce81) and a minor spike about 6 hours after that.

[google-appengine] Re: Increased CPU Time/Request after yesterdays maintenance?
We're having the same issue. Worked fine until the maintenance, as far I remember. Now our logs are filled with: # # Request was aborted after waiting too long to attempt to service your request. This may happen sporadically when the App Engine serving cluster is under unexpectedly high or uneven load. If you see this message frequently, please contact the App Engine team. # Even we do only get about 8-10 requests/sec and all our responses are memcached. Any word from the AppEngine Team?

Thanx Ikai, that was the final answer we were waiting for.

Re: [google-appengine] Re: Can Google CDNs cache dynamically generated files ?
I wouldn't call it a CDN, but the caching infrastructure at Google may hold on to static assets with the correct headers set. One of the key benefits here is that you won't be charged CPU time for serving the asset, though bandwidth charges will still be applied. This is only a best effort caching and is not guaranteed, so in the worst case scenario the caching infrastructure will not hold on to your data and the requests will still be routed to your application instances.

Yes, it works ! Thanx everybody. I just added the "Cache-Control:public" header to my content. I cleared my browser cache. After refreshing the page I don't see any log coming from my ZipServingServlet. Cool. BTW if you don't add the max-age info to your Cache-Control header, Google sets it by default to 600 (10 minutes).

I am seeing thousands of errors(all timeouts of one type or another) on requests that typically have less than 100 errors a day. My CPU usage per second is up 20% since the failure this morning. These are requests that usually take less than a second and they are reaching the 30 second mark.

[google-appengine] Problems with App Engine today - Can we get an explanation?
Hi, Can we get an official word on why the App Engine has performed so poorly today? My app has seen hundreds of HTTP 500 errors, is running approximately twice as slow (CPU time/request) as yesterday (PUTs are very slow), had many "HardDeadlineExceededError" errors and stats tools such as AppStats don't appear to be working for me (displays "real" time but not cpu time). It'd be reassuring to know why these problems are occurring and what is being done to fix these and stop the happening again.

Re: [google-appengine] Querying objects that are not part of a criteria
You cannot query on an unindexed property. You'll have to walk through the entire list of students if you want to add a property. If you're doing a data migration to add a new property, the strategy is to do this: 1. Deploy a version of your application that adds the new property 2. After deployment, migrate your new entities. Until this migration is complete, your entities may be in a grandfathered state, but you won't need to worry about new entities being unqueryable.

[google-appengine] Re: Retrieving image from a Blob
@Robert. Right you are. I checked the docs and db.get is a magic get
anything function. Sorry for the noise.
So I'm going for door #2 now. In ServePhoto "photo" must be the
correctly returned key. Otherwise accessing "photo.photo" would give
an error. So photo.photo must truly be a false value. This means to
me that although "photo" is a valid object, the photo.photo property
never got set properly. This takes us back to "UploadPhoto". It's
unlikely that photo.put() failed. And it's likely that "db.Blob"
created a valid db.Blob object. However accessing "photo.photo"
doesn't return the db.Blob object, but rather the underlying data that
came into it. Therefore I think your original hunch that the incoming
data for db.Blob is an empty string is correct. I've struggled with
multi-part posts so I'm not 100% sure about the html. One thing that
looks suspicious is the hard coding of the hostname:port in the post
action. Are you sure you don't want simply "/uploadphoto"? That
could send the uploads to the wrong place, for example different ports
use different datastores on the Dev Server.

[google-appengine] Record Corruption, again...
After last nights maintenance (in fact after every scheduled maintenance) I had a record go corrupt. I have issued a support ticket but would like to expedite fixing this problem.

[google-appengine] Stringified Key format: which characters?
Hello. I am developing an application using django, and I need a regexp to match the stringified keys in an URL, so that I can use urls like "/ view/". I started off using letters and digits, but then I realised searching in this group that the key in its string format is actually a base64 encoding of something. I saw that one of the two symbols used by the google implementation of base64 is the hyphen (-), but I have not been able to experimentally find the other symbol (there must be another one), nor find an answer searching. For now I am capturing all the other symbols that I've read on wikipedia, that is plus (+), underscore (_) and dot(.). I assume that the slash is out of discussion, as Google recommends using keys in URLs. So my question is, as I am a perfectionist :-), which is the other symbol that may appear in the keys beside the hyphen? Thank you very much for your replies, and for the marvellous job in creating AppEngine.

For me, rolling back helped. I was able to deploy my application now.

[google-appengine] Driving a GA with an asp.net backend
Greets - first time poster here... I've developed a IIS7-based webapp that I would like to integrate into a Google App. I understand the out-of-the-box options are Python and Java but surely examples exist where asp.net-based resources are integrated with a Google App?

[google-appengine] Querying objects that are not part of a criteria
This is my first message to this group. Let me know if you think I should post this somewhere else. I am working in a new personal app. My need is to assign a value to all the entities for a store. Let's say I have students with about 1001 students in the store. I want to be able to assign grades to them but they never had the grade relationship before. So let's say it was only Student with name attribute. Grade is going to be new. I understand I will need to make a few ( at least 2 ) fetches in order to traverse this store of students, in order to populate all them with grade. I also understood I could use cursor so I can traverse using multiple fetches and continue from the last fetch point. My question here is related to the fact that I may be doing this operation, but I could miss some student because a new student could be inserted in the database. So by the time I did the 1001 student assigned grades, I new 1002 could show up in the database and he/she won't have a grade. Is it possible I would query for students that don't have a given attribute? Like the lackness of something? Other ideas to solve this problem? Would you know what experienced store developers do? Transactions? Do they fix the New student ( .put ) code first then work on the pending/list solution later? Any lights? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group. To post to this group, send email to google-appeng...@googlegroups.com.

[google-appengine] Re: Can Google CDNs cache dynamically generated files ?
Cache-Control: public, max-age=[seconds as an integer] Should do the trick. "Public" is important otherwise downstream caches (i.e., the Google CDN) won't hold the content (e.g., "private" will be end-browser cache only).

We're still seeing problems on the console.
We're also seeing a large number for DownloadError ApplicationError 5

Or... I have a form for upload of multiple files at once.

Re: [google-appengine] Re: Retrieving image from a Blob
db.get() will grab an entity of _any_ kind. Model.get checks that the
key is for the correct kind of entity before fetching it. Either will
work. When I use db.get I usually include a check to make sure the
keys are the correct kind.
The key he posted in his initial thread is a Photo.

[google-appengine] Re: Retrieving image from a Blob
The one thing that looked off to me is that the line in ServePhoto
photo = db.get(self.request.get("photo_id"))
might want to be
photo = Photo.get(self.request.get("photo_id"))
I think db.get is a datastore method, not an inherited method from
db.Model

[google-appengine] How to control blobstore quota usage?
I want to let my users upload small files (1 Mb < size < 10 Mb) for further processing and deletion. Somehow I'm sure that there will be no more than 100 uploaded unprocessed files at every moment, so, I assume I won't go above free blobstore quota in the very most cases, so I setup quota cap for stored data at 2 Gb and am sure that 1. I will pay at most some cents a day, rarely, 2. there can be no "over quota" error. However, after reading docs and some testing it seems that I shouldn't be so sure. I can restrict files >10 Mb no earlier they are uploaded and counted towards quota (by deleting them in servlet after checking their size), so - anyone just uploads 2 Gb file everyday to make me pay those "some cents". Moreover, for the very short period of time between file is uploaded and servlet checked its size and deleted other users can get "over quota" error. Also I have a thought on how to consume N * 2 Gb of quota, making app owner pay more than just "some cents" in case his quota cap for stored data is much higher than 2 Gb. The questions are 1. Is there a way to restrict file uploads on some condition before they were counted towards quota? 2. If no, is it planned? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group. To post to this group, send email to google-appeng...@googlegroups.com.

[google-appengine] Re: Increased CPU Time/Request after yesterdays maintenance?
My apps are having the same problem. The error rate is nearly 94% for some pages with following errors: com.google.appengine.api.datastore.DatastoreTimeoutException: The datastore operation timed out, or the data was temporarily unavailable. or com.google.apphosting.api.DeadlineExceededException: This request (e368bee26d2ba9cd) started at 2010/09/14 11:18:27.769 UTC and was still executing at 2010/09/14 11:18:57.168 UTC.

[google-appengine] Re: 500 error accessing http://appengine.google.com/
although it looks like this is solved, still some requests take a lot
longer than others e.g. every ~10th request or so takes more than 8
seconds in my application. all other requests take 50-600ms. i would
too appreciate to get some information about those peaks.
kind regards,
ingo

[google-appengine] Re: 500 error accessing http://appengine.google.com/
While things seem to have stabilized, trying to deploy earlier this
morning seems to have "hung" a deployment of mine. I now get an
error:
"Another transaction by user xxx is already in progress for this app
and major version. That user can undo the transaction with appcfg.py's
"rollback" command."
I'm mentioning this for the GAE team just in case this NEEDS to be
done. Otherwise I'm content to just push out a different major
version and eventually delete the stalled one. I'm doing it this way
because I use Java so I don't have the rollback command handy.

I've experienced large increases in CPU time per request since the
maintenance yesterday. I would like to here some official comment
regarding this...
GET and PUTs seem to take much longer than a day or so ago.

Same here -- intermittent outages on the appengine console, as well as

hello app engine team,
i have the same problem.
in general, i love developing gwt apps for the app engine. but this is
not the first time i cannot reach the administration console, cannot
deploy my app or cannot use my app without any warning. there have
been similar errors in the last weeks (e.g. inaccessible svn
repository or the 502 bad gateway error).
please reduce the frequency of 502 and 500 errors as soon as possible.
to me this is very important. already my trust in the platform
decreased a bit.
kind regards,
ingo
