[google-appengine] The Link To WebApp3 NonPublic Repository
Hello there, I've recently looked into using webapp3 with a few wishes: that there is a lightweight framework for working with Google App Engine that evolved from WebApp2, and that the next generation framework supports python 3. The repository listed at this website does not appear to exist, perhaps because it is private: https://webapp2.readthedocs.io/features.html This sort of information is critical for developers looking to adopt the platform or increase our existing footprint. Furthermore, links to documentation for both WebApp2 and WebApp3 are down. Please advise on what I can do about the repository and what's going on with the documentation.

[appengine-java] Re: Date, Calendar question (multiple instances of web application behaviour) clarification
Hello, I am sorry for my late answer. I am trying to implement kind of authorization system to access certain service. This service is only available for example X times per Y seconds (x = 5, y = 60 * 15) each request to this service is identified by uniqueID so I know who is asking the service I use memcache to find out how many requests there were in last Y secs. If number of requests is lower or equal to X I try to put another different entry to cache which contains current date (current app instance date). Subsequential requests retrieve this date from memcache and use it to compute remaining time to next RESET. RESET is meant to be time when first cache entry expires and thus reset number of attemps to request my service. (more simple) I put some date to memcache for example (currentDate + 15 mins), next time I retriev this date, but it can be different app instance than which made the entry. If I do some computation like (dateFromMemcache.toMilisecs - currentAppInstanceDate.toMilisecs) this may vary for app instance. If different for different instace is only few milisecs or secs, it's ok. But if it is more than 1 min or even more that would be problem. Any simple idea how to cope with this ?

Hello again,
I cannot give you straightforward answer,
try to do as little as possible. Create simple entity,
try to create new, delete some by key, createIfNotExists and similar

Also make sure you entities have right key type and such,
your crearPartido method has somehow too many arguments try to make it
more simple.
step by step.

[appengine-java] is there any solution/idea how blacklist IP in realtime ?
Hello, I was looking for some solution which would allow me realtime blacklist IPs. I didnt find any. Realtime I mean without manually getting IP and change dos.xml and upload it. A man can upload dos.xml to bann certain IPs. Can this be done somehow (anyhow) programmatically, even using home computer ? I image it would be possible to let my computer run request every 5 mins to get webapplication abusive IPs and then upload new dos.xml ? Is this only possible solution or I am heavily missing something ? :) Other way I came with is to update dos.xml on gae webapp and somehow trigger it has changed so gae will notice, problem is I dont know how or if its even possible :) Thank you for you time, -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Hi lisandrodc,
please carefully read all documents
http://code.google.com/appengine/docs/java/datastore/
and
http://www.datanucleus.org/products/accessplatform_1_1/guides/jdo/daolayer_design.html
Also many people cannot read spanish, if you would write in english
you may get more
answers.
I think you problem is that you datastore operation failed in catch
block
and since you are closing persistence manager first and then
rollbacking it
fails.
Solution:
1) read everything as carefully as possible, look at example and try
experiment.
2) in finally block rollback first and then close persistence manager

[appengine-java] Re: Sending mail in transaction
I was thinking about storing some unique string which is derived from
email content and recipient (i have some unique stuff sending in each
mail)
and store in memcache/db, I know its not bullet proof but at least in
case
some possible 2x sending mail would be filtered.
Concept :
Check flag if set we know we did send
Send mail, if successful, set some flag in memcache/db
I am aware ITS NOT BULLET PROOF, but maybe can filter some cases, when
same task
is triggered after that interval neccessary to change/store flag.
What you think ?

The request headers will not help.
You'll run into problems whenever you are doing an api call that
return with an unknown state and the method you are calling is not
idempotent (like sending mail, creating a contact etc.)
So in case of email you can add your app as bcc and use a mail-in
handler to check whether the mail has been sent successfully or not.
This is an ugly workaround but there is nothing else that comes to my
mind.

[appengine-java] Re: Sending mail in transaction
dflorey and Pieter,
thank you for the links,
I will look into it asap.

You can check request headers to see if this is a first invocation of a task
(http://code.google.com/appengine/docs/java/taskqueue/overview.html#Ta...),
so you can detect a second invocation of a task.
Maybe if you combine this with specific catch blocks for mail exceptions?

Pieter,
although this looks easy its not that easy, I am aware that I can
queue a mail sending task,
problem is that task has to be idempotent to achiev desired behaviour,
a queue task can be executed for example twice, since those are
specifications
and this would result in sending mail twice,
a naive aproach would be to update some db lock to prevent sending
mail more than 1 time,
but it is not easy, this is much more complicated,
in other words operation is either atomic or it isnt, and without very
precise mechanism you
cannot prove that task will be runned only one.
My own tests proved that due to email quota being reached (task fail
and has be resheduled) some of the mails
has been send twice.
If Mail API would allowed to send mail only in case of some db
transaction success it would be very easy to garant
that mail will be send exactly 1 time. (although if it fails for some
other reasons like recipient not found or so thats whole another
story :)
Basically this can be solved by
1) adding new API for sending mail (dont know if it so easy or whole
problem isnt much much bigger than i think - distributed
transactions ?)
2) implementing locking mechanism
On Jul 12, 9:13 pm, Pieter Coucke pieter.cou...@onthoo.com wrote:
Create a task for sending e-mail instead of calling the mailservice
directly.
use this in your task (a task can be part of a transaction)
try{
...
} catch (Throwable thr) {
log.error(...);
}
and all exceptions will be catched. I think a task will be re-executed
only
if it fails (throws an exception).

Hello,
I would like to ask, if there is some way how to send mail only in
case that some db transaction will be successful.
I am not very experienced with gae, but I did study it now for about 2
weeks.
Desired output:
1) prepare email
2) db transaction.begin()
3) do some db operation
4) bind sending mail with current transaction (similar to
how can you can attach Task to queue)
5) db transaction.commit()
I am aware that I can queue mail sending task to task queue, but i
cannot find the way how to do that mail sending task Idempotent
without (i think) complicated locking mechanism .
Most simple solution would be to put mail sending task to task queue,
but this means mail could be send twice in some rare situation. (this
is maybe not that bad but if there is some way how to avoid it, I
would like to know)
Thank you,
Marcus

[appengine-java] send mail to person + BCC to all admins (strange behaviour)
Hello everyone, I was trying to send mail to per...@domain.com and in the same mail BCC to admins (app has 2x admin) result is that per...@domain.com never receive mail but admins do. I would like to ask if this is intended behaviour. My code is following: InternetAddress [] replyTo = new InternetAddress[1]; replyTo[0] = new InternetAddress(reply_will_be_set_h...@domain.com); Message msg = new MimeMessage(session); msg.setFrom(new InternetAddress(admin_registered_with_this_app_email_address); msg.setReplyTo(replyTo); msg.addRecipient(Message.RecipientType.TO, new InternetAddress( email_address_of_customer, Dear Customer,)); msg.addRecipient(Message.RecipientType.BCC, new InternetAddress(admins)); msg.setSubject(messageSubject); msg.setText(messageBody); Transport.send(msg); i case i remove BCC for admins, recipient.TO will get mail, It looks like sending BCC to admins somehows removes Message.RecipientType.TO, or is it problem in my code ?

[appengine-java] Re: Breaking change in data store?
Hello Marc, this maybe be blind shot, but I think i faced similar problem, problem is I think following (although my primary key was encoded string I believe its the same issue) Description of problem: You have persisted some of you entities WITHOUT setting your primary key (you just let it NULL), so system generated Long. Later you do query or something and access Key property getName() but since given key has id=Long it fails So basically the exception description: The primary key for mymodel.JarData is an unencoded string but the key of the corresponding entity in the datastore does not have a name is correct Solution: Make sure that that you always set primary key prior to saving, or if you want to have more flexibility, and be able to have 1)system generated ID and 2)your app generated ID make sure you check if its Long of Unencoded String by converting primary key to Key object and then make checks before accessing getName() or getID() (only 1 can be set) If I am right this has nothing to do with downtime issue. Hope this helps you, Marcus On Jul 8, 11:39 am, Marc Guillemot mguille...@yahoo.fr wrote: Hi, yesterday my application worked just fine.

[google-appengine] JPA @Lob
Hi all, I have a question relating to @Lob annotation in JPA (when using google app engine datastore): When not annotating a string field, yet placing a string greater than 500 characters in it, I get an exception, asking me to use: com.google.appengine.api.datastore.Text instead. This is fine, I agree that I should not save a string greater than 500 characters in a varchar column. However, when using the @Lob annotation, and persisting the entity, I get the below StackTrace. Any ideas how to avoid this ?

[google-appengine] Pondering move to GAE
Hi all, As I have recently been given a whole new project to work on, with free hands to use whatever tech i like, I'm pondering to move all the code to GAE. I do have a couple of questions, hoping that somebody can clear them up for me. (Note: I know that I'm still thinking traditional RDBMS below, but I need to think in those terms for now) 1. Let's say I have an entity, Account, that I have been using for some time, and there is a lot of data in datastore that is mapped to Account, then one day the I want to add a new attribute to account, let's say age. Usually, I would add the attribute to my class, and then add the column in my RDBMS, redeploy, and all is well. How would this be solved using datastore ? 2. Is it possible to tell GAE never to restrict access to my application (that is, I don't want any limits att all on number of request, no matter the cost). 3. Yesterday when trying to access the admin panel for appspot.com it asked me for SMS verification again, how often does this happen ? I'm sure I have a million more questions, but let's start with these. Thanks in advance for your answers.
