Re: Lazy Registration
A better idea might be to map carts to sessions, and then sessions to customers. Each session has a cart. Each cart may belong to more than one session. A customer can identify with more than one session, although each session can only identify with up to one customer. This way, the customer can put stuff in their cart at home, go to work, add some more stuff, and then come home, and have everything in their cart. The customer has two active sessions because the browser at work and the browser at home don't share cookies. Plus, your logs will have a more realistic picture of what's really going on, since each session maps to exactly one browser.

Re: Using session in new thread
I think the session is StackedObjectProxy. session._current_obj() will get you the actual instance that you can then pass on to your thread.

Fastcgi and performance
Hi all I was told by a programmer (I am not one :D ) that an application that runs Pylons via CGI is not going to be performant in a shared hosting environment and I may not be allowed to use it. As reason for poor performance the programmer indicated the fact the the server will have to spawn a new process each time a request comes. Is that so?

Beginner questions:Pylons and fastCGI -performance issue and some errors
Hi all
I am beginner with pylons and Python and I am trying to move an
Appweblication from a server to a shared host environment. The
Appweblication was developed by somebody else, I am not programmer and
I am trying to learn what it takes to just do the move.
Here is what I am running:
-Python 2.5 installed in a virutal environment because I needed to add
some more modules that were not allowed by the hosting company. They
also run a older version. The provider is Godaddy so if anyone managed
to install Pylons Appweblication there I would be glad to hear about
their experiences.
Python is the ActivePerl version because this version comes with all
the modules that I needed included. I needed sqlite2 but ActivePerl
has sqlite3 I hope that is good. I haven't reach the point to run the
Appweblication
-Pylons 0.9.6.2
-I had to remove Routes Routes-1.10.3-py2.5.egg and to install
routes==1.9
my fastcgi script looks like this
#!/bin/sh
exec /usr/bin/env \
PYTHONPATH=myhomedir/html/Others/Appweb/libAppweb \
LD_LIBRARY_PATH=myhomedir/html/Others/PVE/lib/ \
:myhomedir/html/Others/App/libApp/ \
myhomedir/html/Others/PVE/bin/python /myhomedir/html/Others/Appweb/
Appweb.py
I also tried
#!/bin/sh
exec /usr/bin/env \
myhomedir/html/Others/Appweb/libAppweb \
LD_LIBRARY_PATH=myhomedir/html/Others/PVE/lib/ \
:myhomedir/html/Others/Appweb/libAppweb \
:myhomedir/html/Others/App/libApp/ \
myhomedir/html/Others/PVE/bin/python /myhomedir/html/Others/Appweb/
Appweb.py
The file Appweb.py looks like this
#!/myhomedirhtml/Others/PVE/bin/python
from paste.deploy import loadAppweb
wsgi_Appweb = loadAppweb('config:myhomedir/html/Others/Appweb/Appweb/
production.ini')
import wsgiref.handlers
wsgiref.handlers.CGIHandler().run(wsgi_Appweb)
If I run the Appweblication in the hosted environment using the
command line and paste I am receiving the same warnings as in my
vmware test engine but the Appweblication is starting fine. Obviously
I can not use it this way because the host if firewalled and I can get
to the port that I am using no matter what I am changing it to.
The solution was to try fastcgi with the above files because Godaddy
doesn't support mod_wsgi and anything else.
And now the problems
1. the webser seems to be takind a while to respon (10 seconds?)
2. I am receiving these errors (quting the apache log below). Could
you please help me to figure out what is wrong here?
Thank you

Re: Fastcgi and performance
Assume your host supports mod_python (so you can upload python files, execute them and have the results returned)? If so, http://wiki.pylonshq.com/display/pylonscookbook/Production+deployment+using+mod_pythonmight help. My suggestion though would be to look for a hosting partner that support mod_wsgi...I don't know of any though, and i you find one please share!

Re: Fastcgi and performance
I have pylons running behind Apache/FastCGI on a hostmonster.com shared server and it seems to work well and perform just fine. I have yet to move any logic (controllers, templates, etc.) over from my dev server to the shared host, so pylons is serving static stuff at the moment, but it definitely works and performs reasonably well so far. Say the word and I'll pull some of the config files down from the shared machine and post 'em to the list. Sorry. . .But I got it going a while ago and have not really done much with it yet, so the Apache configuration and other steps have faded from memory. Should be at least similar to what would be required for godaddy.com.

I haven't used FastCGI so I can't answer your specific questions on it. ProxyPass will get you setup very quickly. However, FastCGI is actually the preferred method where I work. It ends up being pretty much like ProxyPass except instead of an HTTP request being sent to the process, it's a set of CGI parameters. That translates to a bit of savings due to HTTP being a bit complicated to negotiate. You can also do things like manage how many FastCGI processes are running and such which makes management nicer as you need to scale up. In a shared hosting environment, I am pretty certain they will want you to use FastCGI. That's because they see which processes are out there and connected to the web server, versus various web servers that are targets for proxy requests and otherwise unconnected. -- Jonathan Gardner jgard...@jonathangardner.net -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: Beginner questions:Pylons and fastCGI -performance issue and some errors
After paying more attention to the docs I realized that I am actually running in CGI mode not in FastCGI. FastCGI is supported only for Perl and Ruby :( So this is why it is slow (see my other post from today) and I don't think I have chances to improve that. It was slow even with the HelloWord application. Regarding your advice: I have done most of the thinks you mentioned. Don't forget that I am not a programmer, all I want is just to move the application. I can't understand why when I run the aplication using paster via command line everythig is fine but when I try to start it as CGI there are some dependencies missing.

There is nothing special that has to be done to FASTCGI setup to support a particular language. If they already have Python installed for CGI scripts, you should be able to use it with FASTCGI. The only dependency is that you may have to install flup into an area in your own account and use it from there instead of it being installed in main Python installation. In worst case you could even install your own Python installation so you can use any version you want instead of any antiquated version they supply. That they say they don't support Python either means they just don't want anyone running Python at all, or they don't understand how FASTCGI works which leaves the question of why you would want to use them if their technical knowledge is so limited. As such, you may want to go find a web host that actually knows about Python and how to host web applications using Python properly. That company doesn't seem to be a very good choice.

In that case, it won't have access to the modules in your virtualenv. If you can get a simple Pylons application running in debug mode, you can insert raise RuntimeError and look through the variables in the interactive traceback. If that doesn't work, just make a simple CGI script that prints the Python path: import sys, pprint print Content-type: text/plain print print sys.executable pprint.pprint(sys.path) import somemodule print somemodule That'll show which Python is running and where it can load modules from. Printing a module object shows which directory it was imported from. Python is the ActivePerl version because this version comes with all the modules that I needed included. I take it you meant ActivePython. I needed sqlite2 but ActivePerl has sqlite3 I hope that is good. I've always used 3. I haven't heard of any compatibility problems between the versions. I haven't reach the point to run the Appweblication -Pylons 0.9.6.2 So it's a pretty old application, more than a year old I guess. -I had to remove Routes Routes-1.10.3-py2.5.egg and to install routes==1.9 Routes has some new defaults, so it's possible these are incompatible with your older application. Older apps often depend on minimization and implicit defaults. (Not that that means anything to you, but it would be the first place to look if you wanted to upgrade the app.) /myhomedirhtml/Others/PVE/lib/python2.5/site-packages/Pylons-0.9.6.2- py2.5.egg/pylons/middleware.py:11: DeprecationWarning: The webhelpers.rails package is deprecated. - Please begin migrating to the new helpers in webhelpers.html, webhelpers.text, webhelpers.number, etc. - Import url_for() directly from routes, and redirect_to() from pylons.controllers.util (if using Pylons) or from routes. - All Javascript support has been deprecated. You can write link_to_remote() yourself or use one of the third-party Javascript libraries. from webhelpers.rails.asset_tag import javascript_path These are due to version changes in WebHelpers. You can ignore these, or downgrade WebHelpers until they disappear. I think the rails warning was added in version 0.6. WebHelpers 0.3.4 is still on PyPI but it's hidden so you'll have to go to the exact URL: http://pypi.python.org/pypi/WebHelpers/0.3.4 . Otherwise you can use 0.6.4 and ignore the messages. Don't use any of the WebHelpers 1.0 betas, because they don't have the deprecated code.

I'm also surprised at those 'make_appweb' and 'Appweb_globals.py' names, and 'Appweb/Appweb' (instead of 'Appweb/appweb'). Current Pylons applications have a 'make_app' function and a 'myapp/lib/app_globals.py' file. Perhaps 0.9.6 was more different than I thought, or perhaps the traceback is corrupted.

I don't know if any of us use GoDaddy or have tried to run a Pylons application on it. I had a GoDaddy domain years ago but have not done webhosting on it. So I don't know if we can offer any specific advice about your import errors. I'm also puzzled by your insistance on
