[web2py] Re: scheduler on webfaction

Which is, to me, a trivial requirement for most production use-cases... I use redis too in standard deployments, it was only for next eyes coming to this thread. So, to sum-up : - For inter-controller communications, you need an external message-broker (Redis/RabbitMQ). - To avoid polling the message-broker, you need concurrency (threads/processes/Eevntlets). Now we can move on to Socket.IO: http://www.youtube.com/watch?v=TH-ZCuOdrQE yeah! What integration for it (if any), already exists within web2py for a gevent'ed-deployment story ? Noone within web2py, but the library gevent-socketio is advertised as simple to inject. I don't know or care much for Tornado... From what I gather, it is similar to twisted in terms of asynchronous-coding requirements... well, tornado is a friendlier implementation of the twisted event-loop for webservers. Given though that the partnership between gevent and socketio is stronger, I'd go for gevent too. The way I understand it, unless there is some special-integration code, then using socket.io, would usually require running an independent gEvent'ed Socket.IO server - and routing /socket.io/* URI's in the web-server to it... It will then deal with all browser's client-socket.io interactions, and inter-operate with web2py via a message-broker (as noted above). Am I understanding this correcty? yes. Also if it was a single process (i.e. you successfully embed gevent-socketio within web2py) with your requirements a message broker would be needed anyway: it's up to you if you want to have a single process serving two masters (standard traffic and socket-io ones) or two separate processes handling their own business. -- --- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] distinct keyword for SQLFORM.grid
Hi I have been struggling with how one could get just distinct records to show with SQLFORM.grid if the query passed to it involved more than one table? Doing an inner join tends to generate a lot of non-unique rows and hence it would be important to just filter out the unique ones. With select, there is support for the distinct keyword but this is not the case with SQLFORM.grid. Using the groupby keyword is one approach but this can get somewhat tedious having to specify the fields to group by in advance and hence, I would like to understand if the omission of support for distinct in SQLFORM.grid is by design?

Johann, I developed an alternative to grid/smartgrid which has most of the features. I can put it on github if you like. Caution: not documented. But I'll put up a sample controller that uses it if you like. The main drawback is the search widget isn't nearly as slick as smartgrid's. And you do have to create your own query parser.

for fieldname in db.mytab.fields: db.mytab.fieldname.represent = lambda x,row:row[fieldname] Two problems above. First, since fieldname is a variable, you cannot do db.mytab.fieldname -- instead it should be db.mytab[fieldname]. Second, in lambda x, row: row[fieldname] the fieldname variable is defined in the scope outside the lambda function. The last value held by fieldname will be the name of the last field in the loop. The lambda functions won't actually be called until after the loop has finished, so all of them will end up referring to the fieldname of the last field. To get around this, you can pass in the fieldname as a default argument to lambda: lambda x, row, f=fieldname: row[f] To make things even a bit simpler, you can take advantage of the fact that you can iterate over the fields directly rather than their names (and you can access each field's name via its name attribute): for field in db.mytab: field.represent = lambda x, row, f=field.name: row[f] Anthony -- --- You received this message because you are subscribed to the Google Groups web2py-users group.

particular, the parameter variable should be a previously defined

[web2py] Re: database query on nested tables
PS. Anyway, I would copy the price into check_in and check_out tables. I
know this is redundant but in any hotel you will have to handle discounts
for each individual client (to handle complaints, friends, etc.) This will
give you flexibility and make it faster.

please do remember that most of the speedup between rdbms and nosql (yes, I'm over-generalizing, but I'm going to state a simple core-concept) is due to the lack of features like this.

Re: [web2py] performance issue time to first byte
As always without knowing nothing about your application is hard to give
more precise answers.
But, first of all, I would do a test in localhost to have a reference unit.
For now let's keep the network variable out.
If you have a shell account in your server do:
curl -o /dev/null -s -w Connect: %{time_connect} TTFB:
%{time_starttransfer} Total time: %{time_total} \n http://localhost/
be sure that curl is hitting you homepage and not some redirect.
In the same host/web2py you can also create a minimal application with
nothing but a controller/default.py that only as:
def index():
return 'OK'
and then time it with curl and webpagetest.

Hi I'm trying to improve my pageloadtimes. And so far I'm doing pretty

the most time it takes to load a page is the time to first byte.
I checked my site with webpagetest.org it takes 0.747s for the first
byte. and quite a few requests take 500 ms or more before the first byte
flows. Is there any way to find out why its taking so long? And a way to
improve tose numbers.

[web2py] Strange Plugin behaviour
Dear web2py users, I am novice web2py user and I've recently started developing my first real project. Unfortunately I'm having some issues: - The plugin-controller code is not update when modified, unless the server is restarted. Example: if there's an error at a certain line and I comment it, i keep getting the same error ticket (in the ticket, the line is not commented, the old version of the .py is displayed). - I have troubles importing gluon.globals in a plugin controller. Specifically import gluon; from gluon.globals import Response returns a ImportError No module named globals exception. However if I try executing the same two lines in the shell or in a normal controller, it works fine. Is anyone else experiencing the same problems? I am using 2.4.5 (.dmg) on OS X 10.8.

Seems fine, but you can't do db.table if table is a variable -- it would
have to be db[table]. Same problem with field1, field2, etc. -- you would
have to do:
db[table].insert(**{field1: value1, field2: value2})
To make it easier, you can do:
def add_to_wish_list(self, db, table, **record):
try:
db[table].insert(**record)
and then call it this way:
wishlist_obj.add_to_wish_list(db, 'wishlist', field1=value1, field2=value2)

Re: [web2py] performance issue time to first byte
Your waterfall showed only static files, which are served before web2py hits any of your application code, so most of those optimizations shouldn't have an impact. Are the high TTFB values only for the static files? Is web2py even serving the static files, or is the web server (e.g., Apache) doing it directly?

Re: [web2py] performance issue time to first byte
First thing I'd do in this case is compile the app, then test again. ;) Don't try other things before compiling. Next thing I'd do is look into caching, it's usually very much worth it. Depends on your app, though. What db are you using? How is the connection pooling set now? You can find out what db indexes are on google, that would be good thing to look into, if not for this one, then for your next project. -- --- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] Re: impersonate any user
Is the reversion back to the initial user working properly?
I can impersonate a user, entering a user id in the
http://.../user/impersonate form,
but when I go back to that form, and entering 0 , although it seems
momentarily to change the user name greeting in the upper right of the app,
if I go to the http://.../user/profile or anywhere else, still the
impersonated user appears.
Have anyone noticed this behaviour?

[web2py] iOS + web2py
I've been working on a news-video iPad app (awards and everything! featured by Apple! brag!) that uses web2py for a back-end server, maintaining a database of videos c and serving them up to the app via JSONRPC. web2py also implements our internal curation UI to the database. web2py has been a great solution for us because it solves a bunch of different problems. 1. it automatically updates our video feeds from their native sources 2. it acts as our analytics collection point and does some first-stage analysis 3. it serves the app with auth services, video meta-data, etc 4. it hosts a dynamic page to share videos publicly on the web 5. it implements our internal curation UI ...all with a single framework, and surprisingly little code. web2py rules. I'd like to hear from other projects with a foot in both the iOS and web2py camps, with a general interest in comparing notes, exchanging tips gossip, whatever. (We're also building our development team. I'd appreciate referrals of experienced developers with those skills, preferably but not absolutely necessarily both, who might like to work on a project like that. Drop me a note and I'll tell you more off-list. We're in Silicon Valley, but are open to remote developers.) -- --- You received this message because you are subscribed to the Google Groups web2py-users group.

Re: [web2py] Re: Need help with impersonate
SOLVED (6 months later)
I put this aside six months ago when I couldn't make it work. Today I
really needed it so I dug out pdb and drilled down into
auth.has_permission(). Finally, the light dawned on me. The table_name
field is a string! Changing it to auth_user fixed the problem. May I
suggest a couple of changes to keep others from stumbling where I did?
The online book current has (emphasis mine):
impersonate allows a user to impersonate another user. This is important
for debugging and for support purposes. request.args[0] is the id of the
user to be impersonated. This is only allowed if the logged in
userhas_permission('impersonate',
*db.auth_user*, user_id).
That should be changed to has_permission('impersonate', *auth_user*,
user_id)
It would also help if auth.has_permission threw a ticket if given a bad
table_name argument, maybe something like:
if not hasattr(db, table_name) and isinstance(getattr(db, table_name),
db.Table):
raise ValueError(Table {} doesn't exist in db.format(table_name))
Thanks,
Mike

[web2py] integrating the stripe library into web2py
I'm recently learning about Stripe, and so far it seems like a great option for credit card processing. I noticed that there is a very simple add-on Massimo wrote to do Stripe charges and similar actions, but it does not seem to at all follow the pattern Stripe was intended to be used. Massimo's module requires actually entering the credit card number, but Stripe is built so that the web app doesn't need to ever see credit card numbers but instead use Stripe provided tokens that represent the credit card info that Stripe has saved. Stripe already has a server-side library that can be installed, which I intend to do (once I figure out how to do it successfully on pythonanywhere---for some reason it isn't working). But it would be nice, I think, to include Stripe's library in the out-of-the-box installation of web2py.

In your homepage you are serving 10 images, at least, in fast_download controller, here it's safe to put session.forget() if not already. It will allow concurrent request from the same browser. Good point. If those images are being served dynamically from a controller because they were uploaded (as opposed to being static assets), then the session file locking will cause each request to be handled serially (only a problem if using file based sessions -- no locking for db or cookie based sessions). In that case, you can add session.forget(response) to the download function (be sure to pass in response, otherwise, it won't actually unlock the file and will be no help).

Well, this is completely unexpected. I really can't think of what would cause the compiled code to run slower than the uncompiled one. Intriguing!!

[web2py] Re: routes in windows service not working??
Did you ever find a solution to this?

[web2py] ZeroMQ in web2py
I'l like to start a discussion about working-out an integration implementation for ZeroMQ in web2py. If not as a built-in, than at least as a contrib. If nothing else, than at the very least a recipe and/or examples, and added documentation about how to activate/deploy the integration. ZeroMQ is, to me, one of the coolest things that have happened to the software industry in recent decades... Gone are the days of monolithic systems - open-source has changed the software world entirely, and there is no going back - the days are the days of the integration,hybrid-system, modularity, and variety of components, and ZeroMQ is fast becoming the best candidate for filling the gaps and being the glue that can best bind all things together - beyond the concept of a static-centralized message broker. Fast, efficient, flexible, easy to use, decentralized, free, cross-platform, poliglot, and for not just for messagins, but also for rpc and REST (the concept, not the protocols), and not even just for networking, but also for itc and ipc. I think the more software will esit that has it buil-in, the more easy it will become to build dynamically changing modular software infrastructures. Now, the first thing that I am personally interested about, is to have a 0MQ-RPC service alongside the existing services. There are already existing python modules that do that, it is only a matter of picking one and integrating is as just another service.

[web2py] Server performance (cpu/memory)
Hi! I have the following environment: 1. Amazon EC2 instance running Ubuntu 12.10 2. Nginx 1.2.1 3. Web2py 2.4.6-stable+timestamp.2013.04.06.17.37.38 4. PostgreSQL (still 8.4, going to upgrade to 9.1 soon) 5. Installed using setup contained on /scripts directory. Everything is working fine, but I still feel that the overall response time / performance could be better. one thing that caught up my atention was that recently (after system/web2py upgrade) I have a higher use of memory and CPU. I was using Apache2 and it was going nuts (near 100% CPU/memory usage). Traded for Nginx and now what's getting some CPU/Memory is UWSGI (not 100% though). Pagespeed Insight (from Google) is ranking the site from 54 to 71 (depending on the page) and it says I could do better on some aspects. So, right now what I'm thinking is if there's anything I could do to help improve performance or if I should start thinking on upgrading my EC2 instance. Any thoughs on that?

[web2py] Re: ZeroMQ in web2py
I really like 0MQ too but I would like to understand a typical test case of integration with web2py. Consider the scheduler for example. The bottle neck is not distribution of tasks (which 0MQ would handle great) but the fact that tasks and main app need to access the database. If the workers do not need to access to the database (for example tasks that send a simple email) then 0MQ would provide a benefit but the problem is no longer web2py specific.

Also, what I state is that I have a problem with performance, that might be related to web2py (or not). I'm bringing up the environment I'm working with because it may help others to understand and help if they want to. Also, Web2py is a framework. And on all of it's versions and during all of it's development, people building it have done a tremendous effort to make it so that this framework can be used on a huge variety of different environments. These enviroments go from the classic batteries included on web2py, to web2py running on windows, linux or mac, with apache or nginx, and even with a large amount of diferent databases. So, if I bring this problem to this list, it 2013/4/10 Ovidio Marinho ovidio...@gmail.com You got a problem with web2py? , What you report is a performance of their work environment and that you can mount a laboratory or hire a consulting firm.

I have the following environment: 1. Amazon EC2 instance running Ubuntu 12.10 2. Nginx 1.2.1 3. Web2py 2.4.6-stable+timestamp.2013.04.06.17.37.38 4. PostgreSQL (still 8.4, going to upgrade to 9.1 soon) 5. Installed using setup contained on /scripts directory. Everything is working fine, but I still feel that the overall response time / performance could be better. one thing that caught up my atention was that recently (after system/web2py upgrade) I have a higher use of memory and CPU. I was using Apache2 and it was going nuts (near 100% CPU/memory usage). Traded for Nginx and now what's getting some CPU/Memory is UWSGI (not 100% though). Pagespeed Insight (from Google) is ranking the site from 54 to 71 (depending on the page) and it says I could do better on some aspects. So, right now what I'm thinking is if there's anything I could do to help improve performance or if I should start thinking on upgrading my EC2 instance. Any thoughs on that?

Massimo's module requires actually entering the credit card number, but Stripe is built so that the web app doesn't need to ever see credit card numbers but instead use Stripe provided tokens that represent the credit card info that Stripe has saved. Stripe already has a server-side library that can be installed, which I intend to do (once I figure out how to do it successfully on pythonanywhere---for some reason it isn't working).

[web2py] Re: ZeroMQ in web2py
I think the more software will esit that has it buil-in, the more easy it will become to build dynamically changing modular software infrastructures I have no idea what you are trying to say there. Anyway, yes, it's cool, you don't worry about message delivery because it's completely out of your control. That's the exact problem with it though, message delivery is out of your control. You have no idea if a message is delivered or not. You can 'queue' tons of messages, and ZeroMQ won't tell you that those messages didn't get delivered. It's cool, but it's not a silver bullet. Contrib may be a place for it though.

If you're talking about a webserver serving a database-backed website, I see no need to use it. Perhaps some esoteric uses could be found for it.

Consider the scheduler for example. The bottle neck is not distribution of tasks (which 0MQ would handle great) but the fact that tasks and main app need to access the database. If the workers do not need to access to the database (for example tasks that send a simple email) then 0MQ would provide a benefit but the problem is no longer web2py specific.

Re: [web2py] Re: .sum() and .count() in grid?
Massimo, do you have a preference as far as licensing? I don't want to discourage people from using it, but if anyone makes a much-needed improvement I would like to get benefit of it. If the ideas are worthy of incorporation into grid or smartgrid, that would be great. I don't do works for hire, so I own the code completely. I'll post in this thread once I've cleaned up the code and uploaded it to github. I wrote it without referencing grid or smartgrid, so it does not take advantage of shortcuts in those two methods. But it does have selectable number of rows per page, and it keeps any query, orderby and rows per page parms in the session, so if you go off on an excursion to edit something, it retrieves the index just as you left it. Also things like the console maker are split off into separate functions. I thought this would provide a couple of advantages. If you wanted a console or paginator on some page, you could easily incorporate it. At the same time, if you wanted to substitute a different console building function, you could easily do so.

For the code to be incorporated in web2py (grid/smartgrid/etc.) you should sign the web2py contributor agreement which means you can do what you want with the code but I can too.
