Re: [web2py] Re: please explain this

[Thadeus Burgess]

Escape will convert the text to html entities. For example,

>>> x = "A 'quote' is bold"
>>> print response.write(x, escape=True)
A 'quote' is bold

This protects your page from html injection hacks. If you need to display
html from a variable and you know absolutely sure that it is safe, use

{{=XML(x)}}

Which also provides some helper methods to allow you to select "safe" tags
without allowing everything.

[web2py] Re: inter-component communication

[weheh]

I don't understand. Let's say app has 2 components, a and b, each with
its load view. I have discovered that an ajax that causes a to go to
the server can then have a update b by returning a
jQuery("#b_some_id").html("hello");

I discovered this because I'm completely recasting my app as
components and all the ajax scripts from before still work (after
getting updating urls). I know this isn't what the doc describes
(using response.js), but is it kosher, anyway?

[web2py] Re: memory leak - model remains in memory after requests

[Timbo]

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.

I'm tending to side with Massimo.  Caching issue?

[web2py] please explain this

[Sahil Arora]

what do you mean by word 'escape' when we say escape = False

or
in
{{=x}}
Variables injected into the HTML in this way are escaped by default. The
escaping is ignored if x is an XML object, even if escape is set to True.

[web2py] Re: inter-component communication

[mdipierro]

You can do and there is nothing against it. It just that the
components should not directly communicate serverside, execpt by
sharing data in session. The component can return response.js with
client-side instructions that affect other components. That is the
idea and that is fine.

Are we sure it is not a cache issue? Caching selects or actions with

I always copy the code from traceback in tickets page and it is copied 
formated. 

We need an option to copy raw text from the code in errors page. 

Most syntax highliters can do that, so I think this could be easy with JS to 
create a raw copy button. 

This would be useful for peeking code in admin/pluginwiki too. 

I mentioned that here before ( sometime when I pointed the Thadeu's weblog 
which has this feature)

I'll try to include (raw, copy, print) buttons as options to highlight.py CODE 
helper and send a patch to explain better what I am saying.

[web2py] inter-component communication

[weheh]

I'm diving into components but the doc says something that could be a
show-stopper:

"A component ... must perform its task independently of the rest of
the page."

I want to be able to ajax click on an item in one component and have
it update a div in another component. I can't imagine this won't be
possible, but the doc seems to suggest otherwise.

Re: [web2py] memory leak - model remains in memory after requests

[Thadeus Burgess]

This is due to the built in rocket server (it is not ment for production).
If you use Apache with mod_wsgi this will not happen.

[web2py] memory leak - model remains in memory after requests

[David Zejda]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

My web2py instance gradually eats memory, during day the consumption
grows up to several gigs, so I have to restart often. According to guppy
most of memory is occupied by gluon.dal.Field and other classes of dal:

The proportion is relatively stable. It seems that model definition
remains in memory after each request. It is probably caused by a weird
reference, but I'm not sure how to track it. Please do you have any ideas?

Re: [web2py] Re: Server slow

[Kenneth Lundström]

I finally had time to find out a little about loggin.conf.

In my logs/web2py.log I get this line:
2010-12-25 01:42:30,097 - root - INFO - time to fetch 1.81220602989

So it takes under 2 seconds to fetch the data and the rest 37 to show 
it? How come?



Kenneth


Were is this logged, I could not find anything in any logs?


Kenneth


try

import time, logging

def testing():
 t0=time.time()
 orders = db(db.orders.id>  0).select()
 logging.info('time to fetch %s' % (time.time()-t0))
 return orders

so you can isolate the problem and see if it is in fetching or
somewhere else (for example session locking).

I tested it on an application running on the test instance. There could

But when I tested loading the same function five times in about 10
minutes I allways 39 seconds to load the data.

2010/12/2 Kenneth Lundström:

Please tell us more about the setup. Are the three instances behind
running on the same server?

Yes.

why three? What do they do?
One is production, one is testing and last one is development. I 
had two

instances running on a virtual server before and it worked fine.

This is not normal but I suspect the problem is with database.
Did you set DAL(...,pool_size=10)?

No, but I tried but no change.
If I try to select more rows:
def testing():
 orders = db(db.orders.id>0).select()
 return orders
It takes 80 seconds to return 1608 rows.
If I change the return to return len(troops) it only takes 1,5 
seconds.

I have no view defined, just trying out the database.

Cool, thanks for following up. I did manage to finally get something working 
and turned it into a new slice:
http://web2pyslices.com/main/slices/take_slice/110

This is for Cherokee 1.0.14 which has a slightly different front-end. I also 
was able to get self-signed certs set up.

Seems like a pretty nice setup.

I just posted some instructions 
here
 for 
Cherokee 0.99.39. I think you can follow the same instructions for 1.0.12, 
but just be aware that the final Cherokee virtual server platform setup 
steps were changed. See the comments at the very bottom of the 
slice
:
*
*

*__D: Virtual Servers -> New (top left) *
*1: Select platform uwsgi and Add *
*2: Configuration File: /var/web2py/config.xml *
*3: Give new hostname *
*4: Documentroot: /var/web2py *
*5: Use same log as "default(combined)" *
*
*
*I could see its working for http://localhost without E,F,G and its 
beautiful!!*


Also a note to the Web2Py-Ubuntu-install script maintainers: "Universe" 
repositories must be enabled in order to find some Web2Py dependencies. It 
was very confusing for me because I didn't realize this.

Re: [web2py] Re: The stability of web2py releases

[Kenneth Lundström]

+1 for a changelog view.

The idea behind a two button upgrade is just as Branco explained, on my 
production instance I´d only upgrade to stable but on my development I´d 
upgrade to newest release just for helping out with testing.


This way maybe not everyone upgrades their production server to a not 
stable release candidate.

For one thing, I don't think the 2-button suggestion is a good idea;
it's just another indirect layer of information that might not be
meaningful if the underlying mechanism is meaningful.  Conversely, if
the underlying mechanism is meaningful, there's no need for the 2-
button solution.   For example, if the release mechanism follows
strictly Massimo's rule that 1.x.0 is likely a feature-introducing
"big release" with potential big bugs, where as 1.x.9 is likely a bug-
fixing release, then users can make intelligent decision to upgrade or
not; so there's no need for 2 buttons.  If this rule is not adhered as
intended, however, then 2 buttons do not help.

2-button solution doesn't solve the issue of making informed
decisions. It solves the issue of having an option between upgrading
to the next stable release, versus upgrading to the next release
candidate. The use-case is valid, and was outlined by Kenneth.
Inclusion of changelog is a good idea as well. The best place would be
the confirmation page for the upgrade action. It may also be
worthwhile to consider a single-button upgrade with a drop-down on the
confirmation page.

It takes a data argument. I'm wondering how to pass data from my form

[web2py] Re: question about ajax(...); return false;

I guess that must be it. I am always using href="#" on my links with
ajax onclicks, so it never redirects even if return false; is missing.

Re: [web2py] Re: question about ajax(...); return false;

[Marin Pranjic]

ok, i made a mistake. just ignore the explanation. didn't test :D
just try experimenting and see what happens.
return false --> prevents reloading, just like massimo said.
if you call function by onclick event in  with a href set, return will
prevent hyperlink event.
you can set href="#" and that will have the same effect as return false.
but i prefer return false

2-button solution doesn't solve the issue of making informed
decisions. It solves the issue of having an option between upgrading
to the next stable release, versus upgrading to the next release
candidate. The use-case is valid, and was outlined by Kenneth.
Inclusion of changelog is a good idea as well. The best place would be
the confirmation page for the upgrade action. It may also be
worthwhile to consider a single-button upgrade with a drop-down on the
confirmation page.

Re: [web2py] Re: question about ajax(...); return false;

[Marin Pranjic]

try this:



   function remove()
  {
  var a = document.getElementById('id');
  var b = (a.parentNode).removeChild(a);
  }
  function add(x,y){
alert(x+y);
return x+y;
}



text


2+3?



now try removing "return false" after add function.
the thing is, if function returnes value, page will be reloaded.
If functions does not have a return value, it will not reload the page.
But using "return false" always won't hurt ;)

p.s. you can see if it is reloaded if you remove text and click 2+3?.
if text is back, it is reloaded.

[web2py] Re: The stability of web2py releases

[VP]

I am also satisfied with the release mechanism, but I'm working on
small apps.  If something goes wrong it's not the end of the world for
me right now.   But I think there are at least 2 reasons why this
issue should be taken seriously.  One is that the word "Enterprise"
must be taken seriously (it was a source of criticism of web2py).  And
things like this is *one* contributing factor to whether or not this
word "Enterprise" means something.   Second reason is that while the
current release mechanism is acceptable, if web2py grows and more
people use web2py to develop critical apps, things like this
inevitably becomes important.

I think there is no need for a complex release mechanism.  I think a
simple mechanism can be effective and sufficient.

For one thing, I don't think the 2-button suggestion is a good idea;
it's just another indirect layer of information that might not be
meaningful if the underlying mechanism is meaningful.  Conversely, if
the underlying mechanism is meaningful, there's no need for the 2-
button solution.   For example, if the release mechanism follows
strictly Massimo's rule that 1.x.0 is likely a feature-introducing
"big release" with potential big bugs, where as 1.x.9 is likely a bug-
fixing release, then users can make intelligent decision to upgrade or
not; so there's no need for 2 buttons.  If this rule is not adhered as
intended, however, then 2 buttons do not help.


ONE SPECIFIC SUGGESTION I HAVE IS THIS:

One upgrade button is fine, but in addition to that, there should be a
summary Change Log, so users can preview the changes.   This together
with the current rule for release (as described by Massimo) should be
sufficient for developers to make well-informed decision to upgrade or
to wait.

[web2py] New QA-Stack version released (beta)

[Julio Schwarzbeck]

Hi Folks, thanks for testing the site, I've released the third beta of
qa-stack, this release includes JANRAIN login, use your google, yahoo,
openid/myopenid accounts to log in into the site, and feel free to
post test questions and answers, there are still many things to work
out but at least you can get a feel of what is to come.

Site is http://beta.qa-stack.com/

qa-stack uses a "point" system to "advance" the user to higher
"roles", which in turn allows you to do "more stuff" on the site, like
ban questions, edit other user's data, mark questions as featured,
mark answers as outstanding, etc. However, a user with lower roles can
be "upgraded" to a higher role by a SysAdmin, this will give you lots
of flexibility, there will be about 5 more cycles of beta releases and
finally a version you can download yourselves and test locally, etc.

Merry Christmas,

Julio

THANK YOU! :) working even better than before :)

BTW - the new DAL caught a couple of my mistakes. Made the change to

Thanks again for quick turn around, much appreciated!

Silly me.
I forgot to convert value into int. (it's in string form '3')

Re: [web2py] Url variable's problem

[Arun K.Rajeevan]

Voila, I found the culprit.
In linux box, I changed *vars={'indx':search_form.vars.indx}** *to* vars={

Note:* key 'indx' is renamed to 'i' (indx is the name of hidden field)

I still don't know, why this occurred. 
it's just a key name (string). still!!!

[web2py] pointing to the DB folder with new DAL

[mart]

Hey,

Trying the new DAL with latest trunk again.  Only one issue left which
is pointing to the DB folder. This used to work, now, no matter what I
have tried, it generates everything relative to the script  making the
connection. This is what I do using pre 1.9x :

tail,head = os.path.split(sys.argv[0])
db = DAL("sqlite://storage.sqlite",
 folder="{0}/blueLite/db_storage".format(tail))

I tried different variations, but all yield the same results.

This is for my build&release system. I use both w2p, the full
framework, and  DAL (outside of the web context - so scripted only). I
need to wipe clean the entire contents of the top level folder, which
includes all scripts as well as the DB every time builds are kicked
off (which is many times a day, many different servers and OS
platforms).

I would prefer not having 2 versions of w2p on each box (time needed
in bootstrapping servers is important).

Anyone with insight convincing DAL  to make use of the 'folder' param
in the connection string?

Thanks,
Mart :)

Not a relevant one that I can think of. If you have the time and inclination, 
it'd be interesting to track down exactly what's going on. Assuming that the

I've been thinking about this one (generally, not the id issue specifically). 
The semantics of accepts() is designed to catch form validation errors and 
provide feedback to the client. It's not designed to diagnose form programming 
errors, and many (most?) of those errors come back looking as though the form 
had not been submitted (return False, nothing in form.errors). 

That reinforces my notion that there ought to be another form variable to 
provide feedback to the designer about why a form was not accepted, say 
form.status. I realize that this might not always be clear-cut, in that in the 
event of some form errors it's not 100% obvious whether there's an error or 
there was no submission. But at least it'd be possible to describe what 
accepts() thinks it saw. 

The intent would be to help with development diagnostics, not so much for 
deployment.

[web2py] question about ajax(...); return false;

[weheh]

Should one's view *always* have a return false; statement immediately
after an ajax request? Why?

Re: [web2py] Url variable's problem

[Arun K.Rajeevan]

Nothing else is changed AFAIK. 
some magic may be. (it's X'mas :D)

[web2py] Re: ajax polling with web2py

[weheh]

Yes, I do have an ajax generated by code inside another ajax. But I'm
not married to that approach, especially if it doesn't work. I'm just
looking for anything that works -- doesn't have to be pretty.

Bottom line, we need a general solution to this problem. User clicks
an ajax-ified widget/link/whatever. This generates a job-queue entry
and a callback. Callback checks status of job and returns one of two
responses. If job finished, returns final view. If job not finished,
returns wait message and ajax countdown to check queue status again
after prescribed time period.

I've cracked my skull on this problem now on two different occasions
over the last 3 months. On many attempts, I feel like I've gotten
close, but in the end have made zero progress. As I said, this is
mission critical to my app, so any help is much appreciated.

See following form

search_form = FORM (LABEL

_for='word', _id='word_label', _name='word_label'),
INPUT 
(_id='word', _name='word', 
requires=IS_NOT_EMPTY

 I used to do something like search_form[2][3]['_selected']=True

But now with 1.91.x this shows an error (Assignment with NoneType or something 
similar)

What happened?

Makes sense since the handling of 'id' is special but only a trace

As Massimo says, they look identical. Could you try switching it back and see 
what happens? I'm guessing that it was some other change, that fixed the 
problem, perhaps involving JavaScript. (Unless the switch from Windows to Linux 
is relevant; that would be interesting.)

I changed following

 redirect(URL(r=request, f='search', args=[lang, word], vars=indx))

to

[villas]

Yes Michele,  +1 to web pages!

I often see frameworks being compared in threaded discussions. That's
such a waste of time when a simple reference to a webpage could tell a
much better and more complete story.

It is a shame that when some newbie enters a search like 'web2py vs
django|flask|rails' they might so easily find some long argumentative
thread peppered with expletives with someone unfairly ranting about
something Massimo said in 2007. This was certainly my initial
experience and I can say it was quite off-putting.

We could then collectively always reference these pages in other
threads. The backlinks would really boost the SEO and the inevitable
scrutiny of devotees of other frameworks would help us keep the pages
accurate and fair.

[web2py] Bug in SQLFORM.factory in version 1.91.4?

[Lisandro]

I've been working with web2py for a while. Lastnight I updated to last
version, and my webforms just collapsed (sorry for my poor english).
Anyway. After some minutes searching for the cause of the problem,
I've decided to start from scratch with an example. I downloaded the
version 1.91.4 (I'm using Ubuntu 10.04). I created a new application.


The model (very simple, I took it from web2py examples):
--
db.define_table('person',
Field('name'))
db.define_table('dog',
Field('name'),
Field('owner', db.person))
--



Then, I wrote the "index" function on "default.py" controller:
--
def index():
form = SQLFORM.factory(db.dog)
if form.accepts(request.vars, keepvalues=True):
response.flash = 'New dog inserted'
dogs = db(db.dog.id>0).select()
return dict(form=form, dogs=dogs)
--
In the view I just added {{=form}} and {{=BEAUTIFY(dogs)}}, just to
see the result of the function.



When I try to run the function, I receive the following error:
--
Traceback (most recent call last):
  File "/home/lisandro/pylicencias/gluon/restricted.py", line 188, in
restricted
exec ccode in environment

self._caller = lambda f: f()
  File "/home/lisandro/pylicencias/applications/prueba/controllers/
default.py", line 14, in index
form = SQLFORM.factory(db.dog)
  File "/home/lisandro/pylicencias/gluon/sqlhtml.py", line 1182, in
factory

rtable = self._db[rtablename]
  File "/home/lisandro/pylicencias/gluon/dal.py", line 3335, in
__getitem__
return dict.__getitem__(self, str(key))
KeyError: 'person'
--


The SAME code, but using SQLFORM(db.dog) instead of
SQLFORM.factory(db.dog), works just fine.
The SAME code, but with an older version of web2py, works just fine.
What happened to SQLFORM.factory? Some bug? Or it's just me that I'm
doing something wrong?

Thanks in advance.

Look here:

I think the double-update button is a good idea. I was going to
suggest/implement the same thing. I haven't looked yet at how the
update works server-side. Will look as soon as I have more time.

[Kenneth Lundström]

Merry christmas to the whole list.

I think this has been suggested earlier but thought I´d bring it up again.

I have two instances of web2py via wsgi and Apache running on my server. 
One reason is the possibility to upgrade my development side everytime I 
log in to admin, that way getting all new features and testing at the 
same time.


Would it be possible to get two upgrade buttons in admin, one for 
"stable" and one for the latest release. Lot of the time there their the 
same. Maybe a third button for trunk, if that is possible.


Is there instructions how to use the hg stuff to use the trunk. Could 
not find the hg command in the book?

I for one am happy with the current release cycle. It is a good balance
between new features and the ultimate stability of release 1.XX.N  where N
is the last version before XX+1 for example. The nightly build is a bit of a
misnomer, many projects (C or C++ mostly) have some automated process that
takes trunk and compiles it to produce a .tar.gz labelled nightly which
"might" work. For web2py we should just hg pull; hg update to achieve that
result. The nightly for web2py is more like a beta because Massimo hand
picks code from trunk that will or will not be in the nightly which could
really be a weekly.

I am currently developing the application I am working on and testing is
easy enough that I test trunk at least daily. The web2py server is quite
easy to use but the code in some places is complicated and has many possible
use cases. It is only through exposure out to the user base that a large
number of use cases of the code get tested. I have even seen problems
reported where something was fixed but used by maybe one person in a way
that should not have worked resulting in the dreaded bug that worked and
became a useful feature for someone.

Once I go to production I will probably move the releases a lot slower
through the installed base. In fact I have 2 beta production systems up now
and only push a new web2py when I push a new version of the application to
the stakeholders to look at.

Massimo provides a fantastic service with the web2py project and I would
not like to see him stifled by a load of process. Anyone that has time to
test will definitely help the quality, if you don't have time, that is okay
too. I personally don't mind doing some release management between where
Massimo is burning the midnight oil and what I let out into the production
systems I have/will manage. The product is alive with new features and bug
fixes sometimes occur in minutes once reported. That is worth a lot.

Oh, I forgot that I've a plug-gin(SQLite Manager) installed in my FF.

I tried that too, but in vein. 
There's no problem at all.

Am I correctly assuming that list reference field get represented as TEXT in

Data is in format like |5| . so it's correct. 

Problem is somewhere else. May be in DAL !!

[Arun K.Rajeevan]

Thank you for suggestion. 
It worked in 1.89.x.

But problem is resolved now.
And for the benefit of others, I get past it by running *dev_appserver.py*with 
*-c* option.
So, the data already there may be caused problem. I changed DB a little bit.
-c option clears datastore.
