[google-appengine] materialized-view & fork-join-loadtest .appspot.com / data pipelines talk

[jeremy]

In the data pipelines talk Brett Slatkin mentioned releasing the
source for materialized-view.appspot.com - is it available yet?

It would also be interesting to look into fork-join-
loadtest.appspot.com

[google-appengine] Instance Count going to 0

[Jeremy]

This is the second time we've seen this happen in the last couple of
months.  We've had an unresponsive app due to the instance count going
to 0.  We're able to get into the administrative console and we see on
the instances tab that our instance count is zero!  The app returns a
404 error message when users try to hit it.  It has lasted about 30
minutes each time and seems to correct itself.  Under application
settings our idle instances is set to 1 and 1.  There is nothing out
of the ordinary in our logs.  We have plenty of quota room left and
our billing is up-to-date.  We really need some answers on this
because our customers are getting unhappy.  Is this to be expected?
Is there anything we can do to avoid instances going to zero?

Thanks,
Jeremy

[google-appengine] What am I being build for?

[jeremy]

For several months I have been receiving a bill for $2.10 for an one
of the apps that I have deployed for an organization a while back.
This cost just arrived without a clear explanation of what "resources"
I was being billed for.  I have several other apps for which I am not
getting billed anything for, so I guess I want clarification on what
about that app has incurred the cost.  It makes me uncomfortable to
receive a bill for something without any clear break down of why, even
if it is for only $2.10.  The app really doesn't consume much data or
bandwidth.  If either of those were the problem, perhaps I could
optimize the app.  But without any explanation, I am not sure what to
do.

[google-appengine] interval intersection - datastore modeling

[jeremy]

i have objects which store a 'start' and 'end' position.

given an arbitrary interval, i'd like to return all objects with which
it intersects.

can anyone think of an approach to modeling this on datastore?

[google-appengine] Re: interval intersection - datastore modeling

[jeremy]

@tristan: there's nothing difficult about individual intersection
tests. the issue is that i can only perform inequality operations on a
single property.

how do i match both the end and the beginning - is there someway to
encode them in the same property?

[google-appengine] storing and rendering comment threads

[jeremy]

How would "you" approach storing and rendering comments in a reddit
like forum? The naive approach i think would be to store comments with
references to their parent comment, then recursively build the forum
tree by retrieving children. I'm sure that would timeout for larger
threads.

One interesting alternative i found was here:
http://github.com/DocSavage/bloog/tree/master/models/blog.py#L137
basically each comment stores it's "genealogy" in a string, making
comments lexically orderable. But that has a number of limitations -
the genealogy string is limited to 500 bytes so there's suddenly a
maximum thread depth, and the ids may exceed the fixed size padded
space.

At first i thought i could solve this by using list properties to
encode the genealogy - then i realized that datastore lists have weird
set-like sorting :\ .. Not sure whether i can salvage this approach.
Can custom properties define their own sorting rules?

Any suggestions/insights would be great.

[google-appengine] "shell" security?

[jeremy]

the shell app @ http://shell.appspot.com/  - are there any security
implications besides allowing users to use arbitrary quota resources
(the url fetch in particular comes to mind)?

for example, could someone use the shell to retrieve someone else's
session id? i'm looking at the code and it seems like the
encapsulation of new.module is the extent of the separation between
sessions. but i'm not sure to what extent new.module's encapsulation
is hermetic.

[google-appengine] Re: key().id() upper bound

[jeremy]

i'm formulating a single composite property which can be finalized at
entity creation time and which will hopefully allow me to retrieve
hierarchical data in a desired order. i don't think i can do this with
multiple properties as they would each require a inequality operation.

also, this property will be user opaque so i think i can get away with
just 8 bytes using base 256!

[google-appengine] time.time() across shards

across shards of the platform, how close can i reasonably expect

for what it's worth - the behind the scenes str->unicode conversion
which the api performs does indeed make it impossible to use the full
8*500 bits afforded a StringProperty... i think there ought to be a
ShortBlobProperty which allows byte encoding as str, but i guess for
now i can encode everything base 128.

[google-appengine] inequality filter on string length

[jeremy]

"To get all results that match an inequality filter, a query scans the
index table for the first matching row, then returns all consecutive
results until it finds a row that doesn't match. For the consecutive
rows to represent the complete results set, the rows must be ordered
by the inequality filter before other sort orders."

Shouldn't it be possible to perform an inequality operation on a
StringProperty and then another inequality on the string's length? At
the moment it's impossible since you'd have to store each string
length in a separate IntergerProperty, which you then cannot perform
an inequality operation on.

So, this limitation seems to be due to the operations GQL gives you to
work with, not because it violates the invariant quoted above?

When you say "later on", where exactly do you mean? If you want to

You can write to the output buffer by doing

Are you calling those print statements in the same scope as

[google-appengine] Re: counting

[jeremy]

so datastore maintains a sorted table for Nevile's ranks, but I assume
these tables don't themselves maintain the index of each entry since
that would mean each insert would require an update of every
proceeding entry?

peter's approach sounds promising. it would be nice to hear from
someone at google how they approach ranking items in this kind of
database.

[google-appengine] filesystem virtualization on top of datastore

[jeremy]

i was hoping to seamlessly virtualize a filesystem on top of
datastore. it seems there is no pure-python approach to filesystem
virtualization, making this impossible. should i give up on this or
have a i overlooked something?

[google-appengine] Re: filesystem virtualization on top of datastore

[jeremy]

yu: this is interesting, but will it provide seamless virtualization
of a filesystem environment? or will existing libraries that make use
of file and os module functions have to be rewritten?

ross: i'm encouraged to hear that, but i still don't see how. there
doesn't seem to be a way to mount a vfs on the appengine platform, and
there doesn't seem to be a way to wrap existing python filesystem
functionality (there was some discussion on python forums about
providing a filesystem api for just such virtualization - the existing
os filesystem functionality would be reimplemented through this api)

[google-appengine] Re: is gaeutilities sessions the only 3rd party session manager?

[jeremy]

Bowman - I think my issue with gaeutilities may largely be that the
default settings seem excessive. Looking at the cookies google.com
hands its visitors, their SID cookie lasts a good decade and seems to
rotate every few hours, not seconds. So at the moment i'm thinking
I'll see if changing the default satisfies me.

Also, at the moment there's a datastore put() on every session-using
request to (at a minimum) update the last activity time stamp. But if
my SESSION_TOKEN_TTL is something like 1 hour, then actually i only
need to update the last activity time stamp if the last timestamp was
more than an hour ago. That would significantly reduce the amount of
datastore writes, no?


re: "I'm just trying to figure out the value in the signed cookie
approach, because if I can figure out a way for it to make sense I
would consider moving gaeutilities to that approach. ":

Do you mean storing all session data in the clients cookie and using a
signature to authenticate it? That approach makes me nervous, although
I can imagine it's actually quite effective. You just store the
session data in plain text but then also include a signature = SHA1
(session_data + secret_key_only_the_server_knows). That way the server
can confirm it was the one who committed the values (and not the
client messing with their own cookies).

[google-appengine] Re: is gaeutilities sessions the only 3rd party session manager?

[jeremy]

Hmm, I'm not sure what "session timing" is.

I have an idea to reduce writes. Instead of updating the sid of every
session individually, give each session a random value between 0 and
C, and have one application-wide value R randomized every
session_token_ttl seconds to an integer between 0 and C, then hand the
client the value of this as a token:

t = (session_id+R)%C

then when a client hands the server a token, you can compute
session_id = (t-R)%C

(you can store the last 3 values of R as is done now for each sessions
sid)

I'm pretty sure there's no analysis attack that would allow a client
to figure out either R at any moment or their own (constant)
session_id. But, i could be wrong about that :\ ... The advantage
would be you're only updating a single datastore entity every
session_token_ttl.

[google-appengine] Re: is gaeutilities sessions the only 3rd party session manager?

[jeremy]

"What I see as a concern with your approach is what happens when the
server wide variable R gets out of sync with someone's version that
was crypted based off of it? The original reason the 3 valid token set
"

that's why i mention that "you can store the last 3 values of R as is
done now for each sessions sid" - so all 3 would be tried as is done
now with the sid list on each session entity. you could also count how
often R has been randomized and hand this iteration index to the
client as part of the token.

i'm not sure about going primarily with memcache - isn't memcache
designed only to be a caching layer? memcache isn't volatile in the
sense of being either up or down. rather, it throws out stored data
"randomly" as far as the developer is concerned as load increases.

[google-appengine] chunked transfer encoding

[jeremy]

i'm running into some difficult with chunked transfer encoding. i'm
certain that the client is transmitting a body, but the request
handler has an empty body.

this seems to be a long standing issue: 
http://code.google.com/p/googleappengine/issues/detail?id=129

is there a work around? is it only on the sdk?

so using netcat as a dummy host, i've confirmed the client is sending
the data i expect:

91
Content-Disposition: form-data; name="content"; filename="content"
Content-Type: application/octet-stream

but self.request.get('content') in the request handler returns an
empty string

it would be nice to have formalized notification of maintenance events

datastore: down - eta 1 hour

hmm, actually it would have to be it's own maintenance api (if
urlfetch went down the app wouldn't be able to access this).

The template directory should also contain the name of the html file.
If the static dir is 'templates' and the html file is
'test_template.html', then it'd look like this:

 os.path.join(os.path.dirname(__file__), 'templates/
test_template.html')

Just to clarify, does this mean I will be able to choose a "Keep only
1 instance Always On" option, and pay less than if I was choosing 3
Always-On instances?

[google-appengine] Re: Fontend instance hours seem to be a bit overcharged

[Jeremy Brown]

Will there be an option for more granularity in "Always On"? Currently
it creates 3 always on instances. My app would probably do fine with 1
Always On instance, and having 3 always on will just cost me more than
I need to pay.

[google-appengine] Re: ArgumentError: An error occurred parsing (locally or remotely) the arguments to datastore_v3.Put().

[Jeremy Truax]

I'm also getting this error. Is there a workaround? It seems to be because 
I'm trying to put too much data into the datastore at once. I'm inserting 
an image blob so that's obviously the reason. I suppose I could compress 
the image but was curious if anyone knew of any other workarounds.

[google-appengine] Re: Understanding 'Frontend Instance Hours'

[Jeremy Chua]

I had a look at the GAE document for frontend instance but not really know 
how it works.
My application currently only does cron jobs and push queue task. Both uses 
URL fetch. But all this are still within limits (< 5%).

My frontend instance is almost 80%.

Correct me if i'm wrong. The quota of frontend instance means any request 
to my web application??
Since deployment, my application doesn't have any request yet!

[google-appengine] Transferring App Balance

[Jeremy Gordon]

I administer several billing-enabled GAE apps.

I'm currently holding an excessive balance in one of my applications, and 
would like to be able to transfer some of this balance to another 
application (billing administrator details are the same).  Is this possible?

Many thanks!

[google-appengine] Debugging UnexpectedStateError while trying to start module.

[Jeremy Bornstein]

I am attempting to convert my backend use to app engine modules and am 
having difficulty.

The simplest place to start seems to be to say that calling 
google.appengine.api.modules.start_module() raises an UnexpectedStateError. 
I'm not seeing any evidence of a startup problem in the logs. Nor am I 
seeing evidence that the startup was attempted.

As a possibly-related aside, my backend is still configured, and appears in 
the UI as a version of the default module. When I call start_module() to 
start that explicitly, I get the same error.

[google-appengine] Re: major bug in live instance hours calculation

[Jeremy Benetz]

I have noticed the same thing but only in one of my apps.  It's rarely ever 
been billed more than a penny or two.  The last few days it has been 
expending the frontend hours up to my billable amount and then it shuts 
down due to quota denials.  The next day when I get the bill, the front end 
hours appear correct (well below the quota limit) and I don't get billed 
anything.  Very frustrating.  I've sent a couple of billing inquiries in 
but have gotten no response.

[google-appengine] Re: major bug in live instance hours calculation

[Jeremy Benetz]

pdknsk,

I did another deployment and the issue seems to have corrected itself.  The 
bug seems to occur during deployment.  Have you tried that?

On a somewhat different note, I did get a response from billing support. 
 My question to them clearly stated that it was concerning a billing 
enabled app. If they had bothered to look up the app id at all they would 
have seen it was a billing enabled app, but their entirety of their 
response was how to enable billing for my app.  That's quality.  Good job 
Google!

[google-appengine] GAE/J Problem persisting updated jpa entities

[Jeremy Craney]

Is anyone else experiencing some trouble when trying to persist or merge an 
updated entity back into the datastore using the cloud endpoint update 
method? Inserting a new entity works fine but when I try to update an 
entity though the gpe generated cloud endpoint update method, the entity 
doesn't update and then the manager goes null. When the close method gets 
called on the entity manager, I get a null pointer exception. 

I have tried changing the method  to use an entity transaction and the 
merge method but I get the same result. 

here is a link that shows the code I'm using and the log from the admin 
console. 

http://stackoverflow.com/questions/22215640/cloud-endpoints-update-method-crashes-at-mgr-close

the npe always occurs at the mgr.close() line.

[google-appengine] Need advice on MySQLdb connection denied by TCP/IP block

[Jeremy Deats]

Greetings all,

First time to post to this forum. So I have a service implemented in 
Python-Flask which I am currently running in App Engine. I decided to add a 
short block of mysql code to connect and insert into a mysql database. In 
this case I know the mysql database and related user account are working as 
I have the database configured to accept outside request and the user 
account I have configured to not be bound to specific incoming IP address. 
This has been fully tested from multiple outside servers and the problem is 
definately inside App Engine.

The dump from inside Google Cloud log view shows the failure point. This is 
when the connection is attempted.

File 
"/base/data/home/runtimes/python27_experiment/python27_lib/versions/third_party/MySQLdb-1.2.5/MySQLdb/connections.py",
 
line 193, in __init__ super(Connection, self).__init__(*args, **kwargs2) 
*OperationalError: 
(2004, "Can't create TCP/IP socket (-1)")*


This led me to do some digging and found another user who had the same 
problem with no resolve. 
https://code.google.com/p/googleappengine/issues/detail?id=11971

Responses from others on that thread indicate that indicate that there is a 
problem with using TCP/IP sockets and the MySQLdb library inside App 
Engine. So I'm hoping to get confirmation this is true and curious about 
best work around approaches. It seems odd the MySQL library would be 
officially supported in App Engine only to be blocked because TCP IP 
connections made from MySQLDB calls are not supported.

I am adding MySQL support by including it in my App.yaml using version 
1.5.2 
https://cloud.google.com/appengine/docs/python/tools/using-libraries-python-27

At first I was thinking that hosted in App Engine Flask could only 
communicate with Google SQL (managed MySQL) but In the GCS documentation it 
states explicitly that MySQL databases hosted outside GCS are supported. 
Although it shouldn't make a difference, in this case the MySQL database 
I'm connecting to is hosted in a Compute Engine VM inside the same GCS 
account where the App Engine instance is running.

Thanks,
Jeremy

[google-appengine] Can't Manage App After Creating

[google-appengine] Unable to deploy via appcfg or gcloud

[Jeremy D]

We can't seem to deploy our application, out of the blue, as of yesterday 
afternoon. appcfg only returns a 400 bad request error, no other 
information given. Below is a copy of what gcloud returns, seems to offer a 
bit more detail but nothing we can seem to solve on our end. 

*Nothing* about our environment or any fundemental code has been changed. 
There seems to be no rhyme or reason as to why we suddenly can't deploy. 
This is to any version. We also have a separate app ID for testing, we 
can't deploy to that either.

[google-appengine] Re: Trouble with dispatch.yaml

[Jeremy D]

First thought here is that because dispatch checks these routes *in order,* you 
have a "/*" route ahead of "/notifications", so no routes will 
ever reach notifications, because your wildcard hits it first. Move the 
notification route ahead of the wildcard, and you should be good.

[google-appengine] Re: Unable to deploy via appcfg or gcloud

[Jeremy D]

Early solution seems to be running imageoptim on a number of image files we 
have. These images haven't been touched in _months_ so I'm not sure why 
this problem is happening now but, cleaning those images of various meta 
data seemed to do the trick.

May have found the culprit. Possible that one of us working in dreamweaver

that got checked into our version control.

[google-appengine] High untraced time on lightweight endpoint

[Jeremy D]

Seem to have random high untraced time on various endpoints, but most 
noticeably one that should always be responding well under 1 second, as all 
it does it kick off a Task based on request data. Most of the responses are 
around 100ms, some are even below that. Occasionally though, this endpoint 
runs into 5 to 10 seconds of latency. 

[image: Screen Shot 2019-05-14 at 4.04.52 AM.png]
It's not a request that triggered spawning a new instance, and many of them 
aren't either so I'm not sure why the untraced time is so high. Any 
thoughts?

As you can see in the screenshot, this was not a request that spawned a new 
instance. Memory usage also doesn't appear to be a factor here.

Nope. This is automatic scaling.

[google-appengine] Request errors out and kills instance with "The process handling this request unexpectedly died"

[Jeremy D]

I have an endpoint that accepts a date range. A short date of a year 
returns data fine. More than a few years, it takes about 25 seconds or so 
before returning a 500 error with no response in the body, but in Logging, 
I see this:

"The process handling this request unexpectedly died. This is likely to 
cause a new process to be used for the next request to your application. 
(Error code 203)"

This seems to also kill the instance that the request was ran on, and spins 
up another. This means a user could potentially continue to try and make 
this same request and have it constantly killing and restarting instances, 
slowing down response times everywhere else.

Is there a way to get more details about whats going wrong here?

[google-appengine] Re: Request errors out and kills instance with "The process handling this request unexpectedly died"

[Jeremy D]

Some further investigation, trying this on a separate test version using 
F4_HIGHMEM (we normally run F4), I can see the instance increase in memory 
usage dramatically until it reaches 1GB, and then it errors out/kills the 
instance. So, it would seem this is a memory limitation. I thought there 
were other sort of "fail safes" in the event the instance uses too much 
memory?

[google-appengine] Migrating from Standard to Flexible, logs don't show up the same way

[Jeremy D]

I imagine there's more setup to be done but can't find any documentation 
about it. 

Using python standard, any time we use 
logging.info("whatever log")

it gets sent to Logging under the request, with an icon for what level 
severity, like this:


In Flexible however, when we log something in the exact same way, its 
spread out across Logging as individual log entries, making it extremely 
difficult to read the logs/get any sense of actual errors.



How can we fix this so that we only see *one *single line item per request, 
and any logs within that?

This is an immense hindrance to Logging and really really does make it

[google-appengine] Tasks not being delivered

[Jeremy D]

We're having problems with Task requests not being delivered. In Logs, I 
see "Status: INTERNAL" before it triggers another retry of the task. The 
instance its trying to reach has no logs it ever even attempted to make the 
request. Nothing has changed on our end, this is being triggered from an 
Appengine Flexible instance and being targeted back to the same instance.

I should also mention, some of these requests do reach the endpoint, most

[google-appengine] api to determine if application is running on a development server?

[Jeremy Faller]

Hello all:

I've been fooling with AppEngine and the Google Maps APIs, and I'm
running into a bit of a snag.  The Google Maps APIs require a 'key'
url parameter.  The key parameter is hashed to your domain name, so if
I've got a  tag from localhost, the key differs than from when
I'm running on the Google servers.

I'd like to programmatically switch the key depending on whether I'm
running in the development server on my localhost, or on Google's
infrastructure.  Does anyone know an API that I can call that will
tell me if I'm running in debug mode or not?  Specifically, I'm
looking for (in python):


_LOCALHOST_KEY= 'ABQInfs7bKE82qgb3Zc2YyS-
oBT2yXp_ZAY8_ufC3CFXhHIE1NvwkxSySz_REpPq-4WZA27OwgbtyR3VcA'
_MY_DOMAIN_KEY = 'xyzpdq'

def GoogleMapsKey():
  if IsRunningLocalHost():  # What's this API?
    return _LOCALHOST_KEY
  return _MY_DOMAIN_KEY


Thanks in advance.

Regards,
Jeremy Faller

[google-appengine] Re: Too Many Versions (403)

[Jeremy Truax]

Crap I just got that, it's been working fine before that today.

I did notice they changed some quota stuff as of tomorrow, I think but
it doesn't say anything about a limited number of versions.

The issue for this is here:

I'm having the same issue. I get an error "Too Many Versions" when I
try to "appcfg.py update".

I've tried rollback as well as incrementing the version number in my
app.yaml with no resolution.

I'm on version 1 still. My daily upload quota is still at 30 of 250
for the day so it's not like that's even maxed.

I'm having the same issue. I get an error "Too Many Versions" when I
try to "appcfg.py update".

I've tried rollback as well as incrementing the version number in my
app.yaml with no resolution.

I'm on version 1 still so I don't have the option of changing to
another version to try it as the default version is 1 and you cannot
delete the default version.

My daily upload quota is still at 30 of 250 for the day so it's not
like that's even maxed.

[google-appengine] Re: Implemented Keyword Search

[Jeremy Truax]

Yes you're right Wooble. This works great for what I'm indexing which
is something like company names.

It would not work at all for much bigger text (such as blog posts).

In fact, I ran into the max index boundary shortly after implementing
it and had to limit it to the first 5 words only.

[Jeremy Truax]

Yah I had tried incrementing to version 2 and then 3 with no success.

I then let it sit and did something else for about 30 min.

Came back and version 3 worked.

I hate when something just works and there was no resolution as to
what was the problem.=/

[google-appengine] Re: How To Communicate Between App Engines

[Kajikawa Jeremy]

When are the payment plan options coming into effect?

Im already using 3 Appspot domains and have need of more along with
additional db space
 will be required for each of the Applications I am making.

I am currently working on a distributed system.

I am looking at needing to scale upwards for 1000s of accounts on at
least 2 of the 3
 existing applications and would like to handle this without running
into the limits or
 have a means of being billed based on scaled usage if that option is
under consideration?

Sincerely,
 Jeremy

[google-appengine] Re: Is Google the only hoster for all Google Apps?

[Kajikawa Jeremy]

GoDaddy does Domain Name Service Accounts
 and Google provides the hosting.

Domain Name Service being the mapper between domain<->IP,

Ive not seen anything on the GoDaddy system for actual hosting of
content.

right now Im in the middle of trying to construct a custom pair of sites
linked by XRDS-Simple
 with OAuth and OpenID support beyond Basic Authenticated sessions :)

if anyone wants to discuss details they are welcome,
 as I know I am very-new to this use of Cloud Computing.

personally thouigh I did work out a means of setting up my own localized
AppEngine
 on my own Webserver and use it for serving my own developments
 (http://server/domainname/ mapping the projects)


Sincerely,
  Jeremy

[google-appengine] Re: Very urgent

[Kajikawa Jeremy]

Actually I have a similar requirement and found that instead of worrying
about
 doing anything in the webapp beyond the single resource its easiest to
 reply with direct HTML as a raw result without putting any real HTML
into the tags

since the WSGI runs directly similar to a CGI with stdin and stdout
being the socket
 connection made.

Im experimenting with skipping WSGI and using raw incoming and raw
response
 processing using an own XML setup as well.

I can tell you how I get on if you like?
