[web2py] Re: Rocket with urllib2 behavior [BUG?]
I had one more thought, does '/server/default/index' point to this code? If this is the case, then you have an infinite loop that consumes all available threads and deadlocks. Again, this is not a rocket-specific behavior. On Feb 6, 10:08 am, Timbo tfarr...@owassobible.org wrote: If you've only got one thread running, then yes, this will deadlock on any threaded server.

It only creates infinite loops if it's in the welcome application...which it isn't (as I specified in step 2). In either case, we still need more information.

[web2py] Re: memory leak - model remains in memory after requests
So you do use caching? Is it RAM caching or disk caching? If RAM caching, it could be that running under Cherokee and uWSGI is deleting the environment that web2py is run in after a certain number of requests. This would reduce the usefulness of a RAM cache but would also produce the results you're seeing. Whereas a Python-based server (Rocket or Cherrypy) would not do this and a RAM cache would persist as long as the server process (or until otherwise deleted). Please let us know when you look into the possibilities of caching being the issue. @ron_m: Awesome. Great suggestions! -tim On Dec 25, 3:20 pm, David Zejda d...@atlas.cz wrote: Thanks for the all replies!

With Cherokee uWSGI the problem has gone. Moreover the new setup is subjectively faster to the previous one (Rocket behind Apache proxy). :) David

Thadeus, You seem to have more knowledge about this problem. Can you file a bug report? Did you know that Rocket was recently updated fixing several bugs (and creating one that has already be addressed). I'm not denying the possibility, but let's be a good open source community. David, If your environment allows it, please replace rocket.py line 1071 break with return. Note that this will put a hard limit on the number of requests/second rocket can serve to the number of min_threads set. If the problem remains after that, then rocket is not the issue.

[web2py] Re: Rocket 1.2
Thanks Jonathan! Yes, that's all correct. I forgot about uploading new documentation but there are no significant changes in the documentation. The thread count advice for Jython still holds. -tim On Dec 3, 12:17 am, Jonathan Lundell jlund...@pobox.com wrote: Rocket 1.2.0 (web2py's embedded web server) is now in the trunk. It have various improvements, which perhaps Tim will describe. There is one user-visible interface change that might affect some of you. In the previous version, Rocket's min_threads and max_threads were 10 and 1024 respectively. The cli (and winservice options) --numthreads option allowed the user to override min_threads. In the new version, the Rocket defaults are 10 and 0 (meaning no upper limit), and the cli options are --minthreads and --maxthreads (--numthreads is provided for compatibility, meaning the same as --minthreads, but is deprecated). If you're running CPython, my impression is that you need to do nothing, and if you've been ignoring thread-count options, also do nothing. If you've been patching maxthreads, the new default of 0 may work fine for you, and if not you now have command-line access to it. Tim suggests increasing minthreads to 64 for a production server. If you're running JPython, Tim has some thread-count advice for you here:http://packages.python.org/rocket/usage.html(it's for 1.1.x, not 1.2, but I assume that it still applies). If you're running winservice, numthreads is now ignored; you must use minthreads and maxthreads (assuming that you want something other than the defaults). Again, this is in the trunk, and unless the wheels fall off will be in the next release *after* 1.89.5, which is current-stable.

Rocket 1.2.0 is out. It addresses the issue above and has some speed improvements (though that might not be noticeable to the user). If you look at the code, it's much cleaner than it was and reflects my maturing skill as a developer. I've tested it on cPython 2.4 (the legacy branch support Py2.4), 2.5, 2.6, 3.1, Jython 2.5.1 and Pypy 1.4 on Windows 7 and cPython 2.6 on Ubuntu.

[web2py] Re: ssl and http web2py command line issues
Dave,
Sorry it's taken me so long to get back to you on this. I've taken a
quick look at this and need a little more information.
First of all, you're using one file as your key and your cert file.
But the file you've supplied only contains a cert. Naturally it can't
used as a key unless it contains a key.
http://docs.python.org/dev/library/ssl.html#combined-key-and-certificate
At this point, I'm only addressing the potential issues with Rocket.
So I'm not going to address the admin-disablement thing.
Currently neither Rocket nor web2py verifies that the key and cert
file you supply actually match each other; Rocket just trusts that you
know what you're doing. Hence why zeroing out a line does not prevent
it from serving what you give it.
I don't see an easy way in Python to match the two right now. I've
only done a cursory look, but if you know a better way...I'm all ears.
Cheers,
tim

Here are some thoughts:
* If not running SSL and you specified a non-loopback interface for web2py
to run on, the command line should warn about possible disablement of
admin site?
* Check that if you specify a cert on command line, you need to specify a
key (and vice-versa?)
-- The command line silently fails (although there is checking in
main.py:)
if not ssl_certificate or not ssl_private_key:
logger.info('SSL is off')
* Do a check that private key and cert match.
And now for the more interesting item, for some reason SSL connection still
works with the following cert private key (note:I zeroed out a line in my
private key!)
Am I missing something here...?

[web2py] Re: Rocket cache response
Whoa back up. Rocket doesn't set the content-type at all, web2py
takes care of that (streamer.py, line 63). Actually, Rocket will send
on whatever headers it gets, I think Cherrypy was a little more
selective, which may be one reason the Rocket switch would let this
show up.
W.R.T. the slow requests, Rocket has some pretty verbose logging built-
in that web2py doesn't expose (http://packages.python.org/rocket/
usage.html#logging) Can one of you who is experiencing this problem
run web2py from this script:
---
import os
import sys
import logging
import logging.handlers
log = logging.getLogger('Rocket')
log.setLevel(logging.DEBUG)
log.addHandler(logging.handlers.FileHandler('rocket.log'))
try:
path = os.path.dirname(os.path.abspath(__file__))
except NameError:
path=os.getcwd() # Seems necessary for py2exe
if not path in sys.path:
sys.path.append(path)
os.chdir(path)
import gluon.import_all
import gluon.widget
# Start Web2py and Web2py cron service!
gluon.widget.start(cron=True)
-
Please use this to create a debug log of a delayed request (the more
the merrier) and email it to me. As a side-note, some of you have
requested some features for Rocket. I'm limiting development to
essentials right now because of a case of dual-arm tendinitis.
Thanks.

[web2py] Re: Will rocket close connections if it takes long time?
Candid and I discussed this off list. The sum-up is this:
Iceberg, you hit the nail on the head with my position.
However, it's clear that not everyone uses this feature and it may be
more useful to others if it had a configurable thread-timeout. I told
Candid that I'd investigate the effort it would take to add this
feature. Stay tuned.
Whether or not Massimo thinks this feature would be good for web2py is
up to him, but even if added, it would not be the Rocket default.

I have different opinion, Candid.
As Timbo and I have discussed in this thread, rocket differentiates long
running requests, seeing it is caused by client side or server side. Rocket
only terminates long request comes from the client side, say, a very slow
http request from a client (possibly a DoS attack). On the contrary, on the
server side, it is the app (a.k.a. its developer) 's responsibility to ensure
most requests can be served quickly, and it is also developer's right to
occasionally do long time calculation whenever needed. Rocket gives developer
the flexibility to choose what they want. That is better than killing a
(long) running thread unconditionally.
I love rocket. :-)

Thank you for clarification, Timbo.
Is not #3 a problem though? If Rocket doesn't terminate the request if
it's running for too long, is not Rocket's thread pool going to be
exhausted if it runs too many long running requests? The problem here
is that one application could potentially exhaust all working thread,
preventing rocket from serving request for other applications. It
looks like this is what's happening to one of my server - see this
discussion:http://groups.google.com/group/web2py/browse_thread/thread/34f5411692...

Browsers such as Chrome and FF will leave a connection open for quite

away from the Rocket-running server domain). Rocket basically wants
to keep those connections open since they don't cost significantly to

A more featureful admin app would be nIce but I support Massimo in keeping the current one. A point of clarification, Bespin is merely an editor. Their goal is to eventually create an IDE but it is far from that at present. Other problems include no IE support and it suffers from the same highlighting inconsistancies that plague Editarea since it uses regexp-based parser. It also has no highlighting support for Python. Bespin is interesting but it has a lot of wow-factor without much practicality. I'm watching bespin closely and will let the list know when it is reasonable to consider as a replacement or complement to editarea. - tim On Dec 27, 1:50 pm, mdipierro mdipie...@cs.depaul.edu wrote: I would like to see people build alternatives to default admin app. I do not think it is a good idea to replace admin because I like the fact that it has no dependencies, but more experienced users should be able to use more powerful alternatives like the one you suggest.

[web2py:36217] Re: ext js
ExtJS is not part of Pyjamas or GWT. It is a very advanced and powerful toolkit but doesn't compare well with jQuery (which is just a library). They serve different purposes. jQuery is for websites while ExtJS is for web-applications. There is some overlap, but most people don't need or want a layout manager or datagrid on their blog. With regard to GWT, there is a ExtGWT which is a GWT-like implementation of ExtJS. Basically you do all your ExtJS programming in Java. There is nothing like this for Python at present. (Pyjamas sort of fills this niche, but it doesn't use ExtJS.) As far as money, the company behind ExtJS is shady on licensing. The clear cut stuff is this: 1) If your project is under an approved Open Source License, then you may use ExtJS for free under the GPLv3 license 2) If your project is not under an approved open source license, then they require that you purchase a developers license 3) If 2 is true and you wish to bundle ExtJS with your product such that the users of your product will be developers using ExtJS, they require an OEM license.

what I thought it was doing and that puts \n all over my pages. So
I took it out entirely and things seem OK.
What is re_strings for?

No wonder ppl hate Java.
Massimo, are you going to re-work template.py to work around the bug?
I know that template.py is kinda touchy when it comes to backward
compatibility. I've looked into this a little more and I'm
considering creating a Jython branch as I could really use it.
However the two bugs above might cause problems with my application
code. I'll have to look into that.

I think this is the bug we're dealing with:

Since it's a wont-fix, our only option is to work around it by relying

Jython does support TCP_NODELAY, but it does so in the Java fashion...that is to say only on a client socket.

[web2py:34959] Re: web2py and keyed tables
You are my hero. If you ever make your way down to Oklahoma I'll take
you out for a steak dinner or something.
On Nov 8, 8:46 am, mdipierro mdipie...@cs.depaul.edu wrote:
Denese. You did a fanstatic job. This was needed for some time.
On Nov 8, 7:38 am, DenesL denes1...@yahoo.ca wrote:
A) What are they?
Keyed tables are usually legacy tables that don't follow the
traditional hidden 'id' field construct of web2py tables.
Instead they define one or more fields as primary key.
Currently web2py supports keyed tables on DB2, MS SQL, Ingres (thanks
Chris Clark) and Informix (after pending patch, thanks Hans Murx).
To add support for other DB engines see at the bottom of this info.
B) How do you create keyed tables?
Using the same define_table as before but with one difference, the
table has a 'primarykey' attribute.
db.define_table('kperson',
Field('name','string'),
primarykey=['name'],
migrate=False # for legacy tables
)
db.define_table('kdog',
Field('name','string'),
Field('owner','reference kperson.name'),
primarykey=['name'],
migrate=False # for legacy tables
)
Notes:
1) primarykey is a list of the field names that make up the primary
key
2) all primarykey fields will have NOT NULL set even if not specified
3) references are to other keyed tables only
4) references must use tablename.fieldname format, as shown above
5) update_record function is not available
6) web2py rev.1354 (or higher) has appadmin support for keyed tables.
C) How to use keyed tables?
They behave almost the same way, the differences are explained below.
db.kperson.insert(name='Dave')
{'name': 'Dave'}
note: insert returns the primary key of the inserted record or None if
the record was not inserted
After some more inserts:
print db(db.kperson.name!='').select()
kperson.name
Anna
Bart
Cody
Dave
db.kdog.insert(name='Rex',owner='Cody')
{'name': 'Rex'}
db.kdog.insert(name='Fido',owner='Anna')
{'name': 'Fido'}
db.kdog.insert(name='Rover',owner='Cody')
{'name': 'Rover'}
print db(db.kdog.name!='').select()
kdog.name,kdog.owner
Fido,Anna
Rex,Cody
Rover,Cody
print db(db.kdog.owner=='Cody').select()
kdog.name,kdog.owner
Rex,Cody
Rover,Cody
db.kdog.insert(name='Spot',owner='Bart')
{'name': 'Spot'}
db(db.kdog.name=='Spot').delete()
1
db(db.kdog.name=='Lassie').delete()
0
note: successful operations return 1, 0 otherwise
db(db.kdog.name=='Rover').update(owner='Bart')
1
print db(db.kdog.name!='').select()
kdog.name,kdog.owner
Fido,Anna
Rex,Cody
Rover,Bart
print
db((db.kdog.owner==db.kperson.name)(db.kdog.name.like('R%'))).select()
kdog.name,kdog.owner,kperson.name
Rex,Cody,Cody
Rover,Bart,Bart
D) About compound (multiple) keys.
Compound keys can be defined and used in regular operations by passing
a dictionary.
db.define_table('mperson',
Field('name1'),
Field('name2'),
primarykey=['name1','name2'])
print db.mperson.insert(name1='Bart',name2='Simpson')
{'name2': 'Simpson', 'name1': 'Bart'}
or the equivalent k={'name1': 'Lisa', 'name2':'Simpson'}
print db.mperson.insert(**k)
{'name2': 'Simpson', 'name1': 'Lisa'}
print db(db.mperson.name1!='').select()
mperson.name1,mperson.name2
Bart,Simpson
Lisa,Simpson
But references are only to single key, for now.
Field('x','reference mperson.name2')
For selects you have to split the key manually.
db((db.mperson.name1=='Bart')(db.mperson.name2=='Simpson')).select()
E) How can I add support for DB xxx?
Glad to hear that you want to help, we can use your expertise on xxx.
It is not that complicated.
Step 1:
In gluon/sql.py look for SQL_DIALECTS.
It is a dictionary of command translations for all supported DBs.
Now look for the key that represent the DB you want to help adding in.
We need two new entries in there, one with key 'reference FK' for
field level foreign key and another key 'reference TFK' for table
level foreign key.
Use the entries under 'mssql' as a guide.
Step 2:
In the same file look for the definition of the insert function for
keyed tables (near line 2250 in the latest trunk).
Add your DB to the list in the if statement and add an exception using
the ones already there as a reference.
Step 3:
Test, test, test...
** NOTE **: this is a work in progress.
Please report any problems to the group.
Ideas for improvement are welcome too.

This is Jython 2.5.1 fresh install, 1.71.2 fresh install with only the
changes I've mentioned in this post. There are no bugs for this in
Jython as the answer has always been just increase the recursion
depth. I've tried setting the recursion depth to something
ridiculously high and that made no difference.
Can anyone else confirm/deny this? I'm testing on Windows, can we get

tar zxvf ../../admin.w2p
The second error. Can you help me fix it?
Try each one of these models?
htmlbody{{='hello world'}/body/html
htmlbody{{='''hello world'''}/body/html
htmlbody{{=hello world}/body/html
htmlbody{{=hello world}/body/html
which ones break? Any, none? Please email me privately.

Asthetics aside, it does not solve the original problem very well.
The problem is not being able to do:
import c as d
when d is in apps/init/modules because sys.path is global.
A much better solution is to change local_import to be just this:
d = local_import('c')
Because you are in an app the 'a.b' part is assumed.
Also, I like the , force=True part, but call it reload instead

Python (and web2py) look in sys.path.
If the module is in web2py/applications/yourapp/modules then
web2py/applications/yourapp/modules should be added to sys.path.
This would cause a major problem if there are many web2py apps that
have a file a/b/c.py in modules. The import would find the first one,
not necessarily the one in the current app.
sys.path is not thread safe. There only a global sys.path not one per

So far the suggested solution was not do add the app modules path to
sys.path and instead we used to do:
exec('import applications.%s.modules.a.b.c as d' %
request.application) # UGLY!
This solves the conflict between app of modules but not conflicts with
modules that are in sys.path.
This limits which modules can go in the app modules/ folder because
modules that user absolute imports cannot find their dependencies.
This does not reload modules and one is forced to user conditional
reloads when debugging modules.

I found and implemented a better way. With the code in trunk we can
now do:
d = local_import('a.b.c')

- it searches in applicaitons/currentapp/modules/ before searching in
sys.path so no conflicts ever
- each modules/ folder acts like its own site-packages and you can put
any third party module in there whether or not is uses relative
imports
- you can ask it force reloading modules at every request, great for
debugging modules:
d = local_import('a.b.c', force=True)
This opens the door to better plugins implemented (partially) as
modules.

Disregard the first part of my original post. I've looked at your
code and you've done the logical thing. But your original email did
not state it properly.
For the record of those reading:
If you have a module that you want to use in applications/appname/
modules, with this new addition you can:
mod_name = local_import('mod_name')
and it will pull it in as import mod_name would if applications/
appname/modules were added to sys.path.
For Massimo, I still think you should switch the force param to
reload for clarity reasons.

[web2py:33856] Re: Python 3.1
Just so you guys know, I'm watching Python 3.x very closely and in some places helping it along. Here are the things that need to happen before Python 3.x becomes a viable web-platform (for a new project): - The email module need to be fixed (it hasn't been rebuilt to handle the unicode conversion) - The cgi module depends on the email module - Flup works but it's only experimental and not currently part of the main trunk. Allan Saddi just ported it as a curiosity. - Fast Database drivers Currently there is support for SQLite, Postgres and MySQL, but the latter two are Python-only drivers which means they run 10x slower than their 2.x equivalent drivers. Here's some milestones you can expect: The email team has a goal of having email fixed by Python 3.2. Once that happens, fixing the cgi module will be a cakewalk (I might even do it). So look for that in 3.2.1. I don't know Allan Saddi's plans for flup, but after looking at the code, the prefork fcgi adapter is very Unix-specific. (Uses os.fork() and socketpair()) The multi-threaded one should still work just fine if you don't mind the GIL. Stay tuned. -tim On Oct 26, 8:48 pm, mdipierro mdipie...@cs.depaul.edu wrote: I am wrong. I remember trying this and having problems but I tried again with 3.1.1 and worked fine.

[web2py:33133] Re: vim for the admin editor
Yes, that's me. I'm on the list in digest mode. So I don't catch every conversation. I did contribute this Python parser to Codemirror a while ago. It is ok for most things. I haven't brought it up because I'm still trying to work through some annoyances. Maybe this is my perfectionism speaking. After all, Skulpt is already using it. I don't like how it handles indentation (note the section on strict errors). It should not error there but I made it error to work around an implementation difficulty. Also it barely handles context like the CodeMirror Javascript parser does fully. I've began redoing the parser properly but I always hit an infinite loop that I can't find. So I've kinda given up on it for now. Every few weeks I take another look at it and get frustrated by that same stinking infinite loop. Aside from that...I have used Codemirror Python to edit quite a few Python files and it doesn't suffer from the ghosting and other weirdness that EditArea has. I do miss code folding that I have in a native editor, but one thing at a time. Is Amy Editor still massively slow? Does it lose highlighting sync like EditArea? I haven't used it much. I've kinda been holding out for Bespin. So far Bespin is supposed to migrate to a style of syntax highlighter that codemirror uses, but I'm not sure if that ever happened. If they want it to be successful, it will be a necessity in my eyes. If you want to put it in the admin, I have no problems. It might be good to get some more eyes on it since I don't know how widely it is used. -tim On Oct 16, 8:41 am, mdipierro mdipie...@cs.depaul.edu wrote: I did not know about this project and I think the author is the same Tim as this list.

Not trying to be nit-picky, but ckeditor seems to be less buggy to
me. When I maximize OWW, it does not properly scale vertically (FF

Mostly because it supports tables.
Both editors have the annoying feature of escaping URLs and you cannot
insert things like {{=URL...}} in the popups. This is because they
assume we use it to edit html but we use it to edit a view.
Any JS expert can help me make the escaping optional?
The file to edit is admin/static/openwysiwyg/scrips/wysiwyg.js

[web2py:32953] Re: FYI: Ext JS Designer Preview
Negative. jQuery-UI does not (yet) have an IDE. There are two main types of Javascript libraries: - Help enhance a designed page (jQuery, Prototype+Scriptaculous, Mootools, Dojo, ExtCore) - Generally these are used to AJAX goodness to an already pretty page - Help build a web application (YUI, ExtJS, Dojo+Dijit) - Generally these are used to make an attractive Desktop-like application in a web- browser jQuery-UI is trying to move jQuery from the first category to the second category or allow it to be flexible enough to be in both (kinda like how ExtCore is in the first and ExtJS is in the second). Frankly, they've done some awesome work with the themeroller, but until they have a solid layout system, having an IDE is impractical/ impossible. Since ExtJS designer will not be released for free, I would love to see a free version for any library. -tim On Oct 14, 7:19 pm, Richard richar...@gmail.com wrote: does jquery ui have an IDE for drag and drop?

[web2py:30727] Re: Any comments on Tornado Server?
According to the Performance section of their documentation, they recommend running one instance of Tornado per processor core on your server and then joining them together behind a nginx reverse proxy. Looking at the graph, this makes the top bar an apples to oranges comparison with the rest of the servers compared. We call that propaganda. So basically it's ~33% faster than Apache/mod_wsgi. That's not a big deal. Everyone knows that Apache is the work-horse, not the race- horse. Also note that the CherryPy numbers are for full CherryPy, just simply the wsgiserver that web2py uses. It's great that facebook has found a setup that works for them. But it's probably a bad setup (i.e. overly complicated) for the average web2py user. One of web2py's virtues is easy. Not everything that sparkles is gold. =) -tim On Sep 11, 8:28 am, mdipierro mdipie...@cs.depaul.edu wrote: There are two things that do not convince me. - For a complex web app the time of the web server is negligible over the time to perform SQL queries.

The FriendFeed application is written using a web framework that looks a bit like web.py or Google's webapp, but with additional tools and optimizations to take advantage of the underlying non-blocking infrastructure. The framework is distinct from most mainstream web server frameworks (and certainly most Python frameworks) because it is non-blocking and reasonably fast. Because it is non-blocking and uses epoll, it can handle thousands of simultaneous standing connections, which means it is ideal for real-time web services.

If you have space to fill in a new website design, then your better bet is to add some detail to the A logo that we already like and enlarge it to fill the space. Adding detail could be any combination of: - drop shadow - 3D form - add a bezel to the shape - give the guy in the middle a tie (with two dots for eyes that could make a snake) - make the white background transparent - add texture to the dudes (grid, stipples, lines) I'm just naming some options.

[web2py:28307] Re: viability test on IBM AS/400 i5 iSeries ...
The link I included has an AIX 5.x version of Python which I used at a former employer. It works very well on AIX, I just had trouble with AS400 PASE. What I'm saying is, I was an AS400 noob at the time and so I could hardly tell the difference between PASE and OS400. It might still be a viable option though I haven't tried it lately. -tim On Aug 10, 9:02 am, DenesL denes1...@yahoo.ca wrote: Well that is the thing Tim, this is more of an AIX issue than an AS400 one. My expertise is on AS400 not AIX. Plus PASE is just a run time environment, it is not full AIX. So unless I can get a precompiled version of Python 2.5 (or 2.6) for AIX5.2 PowerPC (maybe even AIX5.1), or a compiled hashlib to re-test 2.4 (and see if nothing else fails) then I am pretty much stuck.

[web2py:28088] Re: Fwd: My thoughts on web2py
It's been a while since I've been around but this seems to be an important discussion that I'd like to weigh in on. Massimo is right. Most of Armin's critiques are thought-out design decisions. The perceived problems from just looking at the code don't play out in reality due to being either a non-issue handled by some other mechanism. The issue of open file-handles is partly an issue and partly Armin showing his ignorance of WSGI. Any iterator passed back to a WSGI server will be closed if it has a close methods and will be appropriately deleted. For all the other instances, yes, we should close them. I'm not going to weigh in on the ORM since I currently do not use it (however, this might change with the new ORM coming out). Fact is, I've used web2py for production purposes for more than a year now and the only issues I've had with my setup were either my own code or issues with python's broken socket library (which the included wsgiserver uses). As for the future of Python...I see cPython becoming what the vanilla Linux kernel is today. That is to say, it's sort of the base-line, but no distribution uses just the vanilla kernel, but they all add their own patches and customizations. Pypy will likely bypass both cPython and Jython in performance and flexibility within the next 2 years and popularity in the following 5. Python developers will refer to cPython more than end-users will actually use it. Google will keep using it since they're investing in Unladen-Swallow, but independent projects will gear more towards Pypy compatibility due to it's platform flexibility, speed and scalability. That being said, Python 3.x will not be adopted as quickly as some would hope. Py3 support is barely on the radar for Pypy and Jython. Frankly, even at Python3.1 it's still horribly broken for web- development. The Cherrypy and Werkzeug devs are building their own versions of the cgi library. Eventually, web2py will need to have some implementation on Python3, but I don't see that as needed for at least 2 more years. Python2 is still going very strong. It will be more than 2 years before Google migrates. They will likely be the driving force behind moving beyond Py2.

[web2py:20889] Re: zk-Direct
Take a look at ExtJS or Smartclient. They have many of the same capabilities but are Javascript based rather than Java based. Most experienced web-devs will tell you, just learn Javascript, it's not that hard, and you'll be glad you did. Most studies show that the speed gains of GWT-style (that is AJAX where the J doesn't stand for Javascript) programming are offset by the corner-cases that the toolkit in question doesn't handle well. A good resource to start learning Javascript is: http://eloquentjavascript.net/ -tim On Apr 29, 11:30 pm, Jason Brower encomp...@gmail.com wrote: I haven't looked at the site.(On a train.) Nor have I ever heard of them. But the design of a site, pictures, borders, content style, etc... of just about any site can be done in web2py. It's all a matter of the effort, and talent, that you throw into it. I for one, am no designer, so when looking for a site design I look at what features I would like to implement and how they should be implemented. Then I make a paper prototype of the site that I give to my designer. (If you want his name he can work for you too. :D) He then produces a color scheme and design that I have imagined my site being. Then you take that design and chop it up into an html production. You can subcontract this too if you like. The last steps are to take the html and chop it up too. What parts of the design need to be static, what parts are dynamic and changing. From this information you can begin building the views for your site. You may want at this point to create some skeleton methods or data to fill the site with. At this point is where this list can best help you. We can help you figure out how to make the site dynamic and interactive with the user. Have you made an HTML website before?

[web2py:10089] Re: Dispatcher
The only part about what you said that I don't think I get is:
---
Ideally all of the processing of routes.py should be done in a
separate WSGI plugin module since there is no need to modify web2py to
implement this functionality. It would be sufficient to look for
web2py_error in the HTTP response header.
---
From reading PEP 333, and seeing how Pylons implements error handling,
what I think you mean is just to beef-up rewrite.py such that instead
of rewrite() returning lambdas, it would return a full error handler.
The part that confused me is when you said there would be no need to
modify web2py...in that context, what is web2py? Is rewrite (or the
WSGIServer) part of web2py?

Right now there are various types of errors:
- URL does not pass validation
- Invalid controller
- Invalid action
- Invalid static file
They all raise HTTP(400,message,web2py_error=) and if
- A ticket is being issues
It raises HTTP(200) but the page shows the ticket number.
The value of web2py_error is added as a parameter of the HTTP response
header and it was intended as a mechanism to allow SWGI filtering and
rewriting of these error messages but not used.
I would like to extend routes so that it has a new item in it
(optional) that says something like
onerror=(
('myapp:name','200:/myapp/static/error400.html')
('name','200:/examples/static/error400.html')
)
where name is the name of error message (we2py_error). 'myapp:' means
this rule only applies to myapp (assuming web2py validates the URL and
can determine the app name.
If the event name happens, web2py will redirect or serve instead
/myapp/static/error400.html?ticket=url=/past/url
with HTTP 200 status.
Ideally all of the processing of routes.py should be done in a
separate WSGI plugin module since there is no need to modify web2py to
implement this functionality. It would be sufficient to look for

Hope I am making sense. I find this a simple and powerful solution.

I actually had that idea a while ago but never presented because I
thought you would be against it. Anyway, I like this concept better anyway.
Here's an idea:
- Have a generic error page (straight HTML, no processing whatsoever)
- When running an error handler function set a request flag that says
this is an error handler
- If an error handler throws an error, serve the generic error page.
This is what google does. http://i36.tinypic.com/b3sw03.png
If you like this idea or come up with other details, I'll code it if you
like. Just let me know.

I think in routes.py there should be routes on error for different
