[web2py] Database access without DAL but with connection pool
Dear Sirs,
I understand it's possible to use databases without DAL.
For example function in controller:
def values():
client = pymongo.MongoClient('localhost', 27017)
db = client.mybase
mytable = db[mytable]
res = mytable.find()
.
return dict()
And of course it works.
But is it fast to connect/disconnect every time in function? What's about
connection pool?
I consider connection pool could increase access to database.
1. Actually I would like to ask how to access to database without DAL but
at maximum speed?
2. Do I need connection pool for fast database access? (I think, yes.)
3. How could I build custom connection pool for database access without
DAL? Or any solution to re-use connections to database server? Any examples?

[web2py] I am trying to build a page to display video files list with thumbnail like youtube do.
Hi ! I am new to web2py and python and trying to build a page to display
video files list with thumbnail like youtube do. I am using Expose to
display files and folder in a browser .its working fine. but how to
add/display thumbnail with each video files contain in a directory. what
should i need to add to get my desired display.
this is my code..

Re: [web2py] Python Performance Issue, Part 2
if threads=0 does not work use threads=1 and make mod_wsgi happy. If you remove threads it defaults to 15. 2014-03-19 4:34 GMT+01:00 horridohobbyist horrido.hobb...@gmail.com: threads=0 is no good–Apache restart upchucks on this. BTW, I haven't experimented with the threads value. Might this also improve performance (with respect to GIL)? Also, I was wondering. Is the processes= solution related to whether you are using the prefork MPM or the worker MPM? I know that Apache is normally compiled to use the prefork MPM.

Re: [web2py] Python Performance Issue, Part 2
Did you explicitly set the number of threads as well? By default you get 15 threads per process. The documentation implies that this is a hard limit, but I'm not sure. Maybe you have simply found a bottleneck in threads. Did you also try increasing the number of threads instead of adding more processes? Multi-threaded apache is supposed to be faster than multi-process apache under real load (i.e. multiple users) because starting processes is expensive in time and memory. So any conclusion that you need more processes is dubious, I think. I can't recall how many simultaneous users your benchmarking is testing. Bear in mind that the fastest servers, the greenlet or co-operative async servers, are not only limited to one process, but even to one thread.

Re: [web2py] Python Performance Issue, Part 2
Multi-threaded apache is supposed to be faster than multi-process apache under real load (i.e. multiple users) because starting processes is expensive in time and memory. IMHO under linux the difference is really negligible. Popularity of threads rose in mid '90 because a very popular OS was not able to do forks properly. Java developed threading API, instead of a multiprocess and message passing API as a consequence of that flaw. Today there is no need of threading in general concurrent programming, unless one is stuck in Java. 2014-03-19 10:24 GMT+01:00 Tim Richardson t...@growthpath.com.au: Did you explicitly set the number of threads as well?

Re: [web2py] pysimplesoap help
Hi mariano i still got some problem
I solved the problem with the basic authentication but i still have some
problem on calling webservice.
The webservice infact need a first call for the db connection ('init' )
After this call you can call the other services.
I made this code :
from pysimplesoap.client import SoapClient
from pysimplesoap.client import SoapClient, SimpleXMLElement
location_wsdl =
*http://docway.demo.3di.it*/3diws/services/eXtraWayhttp://docway.demo.3di.it/3diws/services/eXtraWay
wsdl =
*http://docway.demo.3di.it/*/3diws/services/eXtraWay?wsdlhttp://10.55.38.247:8080/3diws/services/eXtraWay?wsdl
namespace_wsdl =
*http://docway.demo.3di.it/*http://www.google.com/url?q=http%3A%2F%2Fdocway.demo.3di.it%2F3diws%2Fservices%2FeXtraWay%3Fwsdlsa=Dsntz=1usg=AFQjCNFAe47af7Nlfx1k8KJR8x-hsRTOAg
3diws/services/eXtraWay http://10.55.38.247:8080/3diws/services/eXtraWay
import base64
username='admin'
password=''
auth = base64.b64encode('%s:%s' % (username, password))
client = SoapClient(location = location_wsdl,
wsdl=wsdl,*sessions=True,*namespace=namespace_wsdl,
http_headers={'Authorization': Basic %s %
auth},username=username,password=password)
client['AuthHeaderElement'] = {'Authorization': Basic %s % auth}
client.send('init',xml=xml_init)
client.send('executeQuery',xml=xml_execute_query)
When i call the 'executeQuery' i got as response that the connection is not
established. The connection should be established with the 'Init' call .
I got the same problem with SOAPUI but i managed to solve the problem
activating the option Maintain HTTP Session
Even putting sessions = True is not solving the problem
Thank for help
Piero

Hi piero:
The first choice to connect to a webservice that requires username
password (add_credentials), you will httplib2 installed:
https://code.google.com/p/httplib2
Then you could do:
client = SoapClient(location = location_wsdl,sessions=True,
username='admin',password='xx')
Also, assuming your webservice supports basic auth, you could pass the
Authentication http header directly (it shouldn't need to install external
library):
import base64
auth = base64.b64encode('%s:%s' % (username, password)).replace('\n', '')
client = SoapClient(location = location_wsdl, sessions=True,
http_headers={'Authorization': Basic %s % auth})
Let me know if this solves your issue,

Re: [web2py] Python Performance Issue, Part 2
In 2007, I wrote my first web application using Smalltalk/Seaside. I chose Seaside because it was a very easy-to-learn, easy-to-program, easy-to-deploy, highly productive, self-contained all-in-one web framework. (It still is, today.) Unfortunately, web2py hadn't been born yet, but clearly the two frameworks had similar goals. (Born in 2002, Seaside has 5 years over web2py.) I deployed the Seaside app under Apache on the same hardware that I'm using today for web2py. Yes, my 2.4GHz quad-core Xeon Dell server with 4GB RAM is over 7 years old!! Recently, I switched over to web2py because I had heard so many good things about it. I can now say that web2py is far superior to Seaside. It's even more easy-to-learn and easy-to-program; it's even more productive. And Seaside was pretty darn good in this respect! I believe web2py is the best available web framework in the world today, regardless of language (ie, Java, Ruby, PHP, etc.). I am 100% in agreement with its philosophy and goals. Please, keep up the good work! On Wednesday, 19 March 2014 07:27:54 UTC-4, horridohobbyist wrote: Yes, processes=3 and threads=1. I tried processes=1 and threads=3, and performance was still 10x bad.

Did you also try increasing the number of threads instead of adding more processes? Multi-threaded apache is supposed to be faster than multi-process apache under real load (i.e. multiple users) because starting (and switching) processes is expensive in time and memory.* So any conclusion that you need more processes is dubious, I think. I can't recall how many simultaneous users your benchmarking is testing. Bear in mind that the fastest servers, the greenlet or co-operative async servers, are not only limited to one process, but even to one thread. http://nichol.as/benchmark-of-python-web-servers On Wednesday, 19 March 2014 14:25:47 UTC+11, horridohobbyist wrote: I shall do that.

After all, I have 4 cores. Why shouldn't processes=4 be good? Anyway, not only is the shipping code fast, but I find that my overall web2py app feels a lot snappier. Is it just my imagination? If processes=2 is boosting the speed of Python in general, then you would expect all of web2py to benefit. So maybe it's not my imagination. Anyway, the takeaway, I think, is that you must tune the Apache configuration for the particular server hardware that you have. The default processes=1 is not good enough.

[web2py] howto: ajax call in FORM with signed URL
Hi,
in a form i have
TD(INPUT(_id='keyword', _name='keyword', _onkeyup=ajax(URL('callback',
['keyword', 'stype']), 'target');), _name=search_type)))
If a text is entered, callback is called an some text is displayed in
target. This works.
But now I want to sign the URL.
If I add @auth.requires_signature() to callback function, it no longer
works. The ajax call must be signed.
@auth.requires_signature()
def callback():
return P(foo)
But how can I add user_signature=True to the code above so that the ajax
call will be signed?
Regards,
Mike

Maybe it is returning a cookie or something equivalent
Then, you can update client.http_headers with them and it should work

client.send('init',xml=xml_init)
client.send('executeQuery',xml=xml_execute_query)
When i call the 'executeQuery' i got as response that the connection is
not established. The connection should be established with the 'Init'

I got the same problem with SOAPUI but i managed to solve the problem
activating the option Maintain HTTP Session
Even putting sessions = True is not solving the problem

Hi piero:
The first choice to connect to a webservice that requires username

https://code.google.com/p/httplib2
Then you could do:
client = SoapClient(location = location_wsdl,sessions=True,us

Also, assuming your webservice supports basic auth, you could pass the
Authentication http header directly (it shouldn't need to install external

import base64
auth = base64.b64encode('%s:%s' % (username, password)).replace('\n', '')
client = SoapClient(location = location_wsdl, sessions=True,

[web2py] Re: Database access without DAL but with connection pool
Well, if you want to do it without the DAL, there are several options that
might just work without any additional code:
- check if specific python libs that you'll use for the db connection
already provide a similar pooling function, they might
- check if the database backend natively provides such a function.
If neither is applicable... I suggest extending the DAL to support a new
database ;)

client['AuthHeaderElement'] = {'Authorization': Basic %s % auth}
client.send('init',xml=xml_init)
client.send('executeQuery',xml=xml_execute_query)
When i call the 'executeQuery' i got as response that the connection is
not established. The connection should be established with the 'Init'

I got the same problem with SOAPUI but i managed to solve the problem
activating the option Maintain HTTP Session
Even putting sessions = True is not solving the problem

Hi,
in a form i have
TD(INPUT(_id='keyword', _name='keyword', _onkeyup=ajax(URL('callback',
['keyword', 'stype']), 'target');), _name=search_type)))
If a text is entered, callback is called an some text is displayed in
target. This works.
But now I want to sign the URL.
If I add @auth.requires_signature() to callback function, it no longer
works. The ajax call must be signed.
@auth.requires_signature()
def callback():
return P(foo)
But how can I add user_signature=True to the code above so that the ajax
call will be signed?

Mike

[web2py] Field.label=lambda ... possible?
Hello,
I am creating a SQLFORM.grid(), and in the update-form for that grid, I
want to display the label value by computing it.
Basically, I have this:
model:
db.define_table('x',
Field('p', type='string'),
Field('q', type='string')
)
controller:
if blah:
db.x.q.label = lambda row: row.p
.
The label is displayed like this 'function lambda at 0x0955FF30'
Not sure if this is supported, or I need to change this code?
Any help?
Thanks,
Kiran

The label is used to label an entire column, so it wouldn't make sense to
calculate a different label for every record. What exactly are you trying
to do?

[web2py] Re: Field.label=lambda ... possible?
Thanks, that makes sense.
What am trying to do is this...
*model*
db.define_table('x',
Field('p', type='string'),
Field('q', type='string'),
Field('r', type='text')
)
This will be displayed in a SQLFORM.grid, with the following caveats:
1. I do not want to see columns for p, q, and r, but rather format the
output in such way that p q r are concatenated.Therefore the grid will look
like this:
|--p+q+r value--|--row buttons--|
2. When I edit the row, the edit form should display:
p (in readonly mode)
q (in read/write mode)
r (is not displayed)
- For caveat 1, I achieved that with the grid's links={} option to
display what I need, in the format I needed it. Something like this links =
[{'header':'Custom stuff', 'body':lambda row: }]. This also means that
I set all the fields to readable=False.
- For caveat 2, I was trying the stuff mentioned in my original post

[web2py] Re: howto: ajax call in FORM with signed URL
you're missing a point: separation of what is executed by python and what
is executed by javascript.
user_signature takes into consideration a/c/f , args AND vars.
your URL link in the onkeyup attribute is generated by python, but then
ajax() takes the values presented in the form (in your case, while the user
is typing values) and post those to the original URL (as vars).
python can't know in advance what values the user will type, and javascript
(ajax()) can't sign the resulting url because of two things:
- it doesn't know what hmac_key to use ('cause only the server knows what
is it, that's the whole point of user_signature)
- it doesn't know HOW to create the signature
If you need signed URLs, you need to verify the url without taking vars
into consideration.
Please review the book about the signature process...
http://web2py.com/books/default/chapter/29/04/the-core?search=signed#Digitally-signed-urls
BTW: auth.requires_signature() takes hash_vars as a parameter too.

[web2py] Re: howto: ajax call in FORM with signed URL
This is logical for me. Thank you for the explanation.
I read the book often, especially the ajax part. I found this sentence: It
is good practice to always digitally sign Ajax callbacks.
Now I ask me:
Is it possible to sign the url and exclude keyword and stype? So that a
user can't submit other vars?
In the book is an example with LOAD, this I understand.
But for ajax in my case it seems now to be impossible to sign it. I have no
idea.
I think I must take ajax callback as potentially insecure and handle this
accordingly.

[web2py] Re: Database access without DAL but with connection pool
I'd say the answer to 2 is 'not really'. Believe it or not, opening and

Dear Sirs,
I understand it's possible to use databases without DAL.

res = mytable.find()
.
return dict()
And of course it works.
But is it fast to connect/disconnect every time in function? What's about
connection pool?
I consider connection pool could increase access to database.
1. Actually I would like to ask how to access to database without DAL but
at maximum speed?
2. Do I need connection pool for fast database access? (I think, yes.)
3. How could I build custom connection pool for database access without
DAL? Or any solution to re-use connections to database server? Any examples?

[web2py] pytds support for mssql?
Back in November, niphlod (?sp) said that he'd look into adding pytds support to DAL. I didn't have a chance to look a lot at pytds until recently, I don't see that it's supported yet. I believe the only thing missing from pytds to be able to add support is the DSN connection syntax. If anyone is interested, I could do a pull request and see if we can get that incorporated into pytds. I just reported a few issues with it and those were fixed (related to transactions on sql 2000), so I think it's mature enough to add. If anyone wants to add it to the DAL, I can offer my support as far as testing and workarounds for some issues it may have (its DBAPI 2.0 support is a little wonky). Why PyTDS? You get MS SQL Server support with 0 binaries required on the host, it's 100% pure python (well, you'd benefit from bitarray, but it's not required). It doesn't use ODBC or anything, just straight TCP. That also means that you could run this with greenlets without reverting to seralized operations. The current pyodbc and pypyodbc still use the platform's odbc drivers which are written in C. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] Re: Pulling data every 30s for a ticker with web2py
If you are pulling data from another web service, take a look at the cache function built into web2py. Use that to get the api results and it will cache the results. Any time the results are requested, if they are older than the expiration time, they will force a reload. The only issue with doing it this way is your server may slowdown while this is going on, so you may want to disable sessions for this particular function call.

Try threads = 30 or 50 or 100; that would be interesting. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.
