[web2py] Re: on a possible web2py memory leak

[ron_m]

Doesn't adding the gc.collect() just force the garbage collector to run 
right now instead of waiting until some usage threshold is crossed and then 
it runs to do the cleanup at some time in the future. Any accumulation of 
heap use until gc gets around to running isn't really a leak, it is just 
uncollected garbage. The __del__ doesn't do anything and also doesn't force 
a gc.collect() by its presence.

[web2py] Re: Can any help me with new dal in trunk?

[mart]

really? I didn't know, thanks for pointing that out...

just out of curiosity

in

in __getitem__
return dict.__getitem__(self, str(key))
KeyError: 'tecnogradua'

don't the attribute lookups get done by python ultimately?  Just
trying to understand...
how could this have worked if doing x.__getitem__ ? Even if dal does a
string.lower() or something, once the table is named and created,
would something (outside of migrate) not catch that error and set off
the alarm even before any change need to happen?

Thanks,
Mart :)

[web2py] Re: Can any help me with crud.archive?

[drayco]

Well, only a litle typo in page 324

db.define_table('notas_archive',
Field('current_record',db.notas),
db.notas)

However all it's works ok.

Re: [web2py] Re: Can any help me with new dal in trunk?

[Thadeus Burgess]

I can also confirm this is a bug with the new DAL.

It is only caused when using upper case characters in the table or field
names. It seems that web2py converts all of the tablenames to lower case
when issuing the SQL (so your actual tables are lower regardless of what you
specify in the python). There is something in the migrations that cause this
to come up, because it will work just fine one run and crash on another run
after changing some unrelated tables.

I don't think the DAL should force the tables to lowercase.

[web2py] Re: Can any help me with new dal in trunk?

[mart]

no, this is python...

not sure how it could have worked before, but the key (technogradua)
in .keys() is not being picked up... dal is simply pointing that out
with the exception being thrown. I did notice when I made the switch
that a few more of my mistakes got picked up (or it could be that I
forgot that I changed something), but regardless... since switching to
the latest DAL release and fixing my mistakes that it quickly picked
up, I have had no problems (except those that I cause). I would simply
take those exceptions for cash, change the case and enjoy one less
exception ;)

Ok, I understand your point.

But this is a issue of DAL or what?

because I only update web2py to trunk version

[web2py] Can any help me with new dal in trunk (2)?

[drayco]

Hi, this code works with web2py 1.83.2 and mysql

but,with web2py in trunk and mysql it doesn't works

cfedb.define_table('med_dnpmst_4',
Field('DireccionUTR', 'integer' , length = 6 ),
Field('Indice', 'id' ),
Field('ValorActual', 'double' ),
Field('Resolucion', 'integer' , length = 4 ),
Field('ClaveMaxyMinIngenieril', 'integer' , length = 1 ),
Field('BandaMuerta', 'double' ),
Field('Tipo', 'integer' , length = 1 ),
Field('ClaveMediciones', 'integer' , length = 6 ),
primarykey=['DireccionUTR','Indice'],
migrate = False)

This is the traceback

Traceback (most recent call last):
  File "/home/drayco/web2py/gluon/restricted.py", line 188, in

Also, I noticed the changeset in trunk included main.py and restricted.py, 
but there were no actual changes in restricted.py. Was there supposed to be 
a change in restricted.py that was mistakenly left out?

[web2py] Re: on a possible web2py memory leak

[Anthony]

As far as I can tell, the change in trunk didn't have any effect for me. I'm 
on Windows 7 with Python 2.7.1 (just using the built-in Rocket server). I 
added the following code to the top of default.py (outside any functions) in 
the welcome app: 
 
class Foo(object):
def __del__(self):
pass
foo = Foo()
foo.payload = [1] * 100
 
I then load the index page of the welcome app and start watching my 
python.exe process memory in the Windows Task Manager. Every time I reload 
the page (by hitting F5), the memory increases by about 7MB, which is 
exactly the same behavior I observe when running the same experiment in 
1.91.6 (i.e., before gc was added). These large memory increases do not 
occur when I remove the above code from default.py. Am I doing something 
wrong?
 
I'm also wondering if there may be a small memory leak either in the 
framework or the welcome app, even without the above code. I notice that 
when I reload the welcome app index page (without the above code), I still 
get small memory increases, on the order of a few KB per reload. It's not 
consistent -- sometimes a few KB, sometimes a bit more, sometimes no 
increase at all -- but memory does consistently creep up as I keep reloading 
(both in trunk and in 1.91.6). Is that expected behavior?
 
Thanks.

More about the subject of circular references:...

http://www.jython.org/archive/21/docs/differences.html

"In Jython users don't need to worry about handling circular
references as these are guaranteed to be collected properly"

CPython uses reference counting instead of proper garbage collection
and suffers from this problem.

[web2py] Re: on a possible web2py memory leak

[Massimo Di Pierro]

Actually this works for all classes but classes that have a __del__
(and this is not a web2py specific problem) so for now:

Attention: do not define classes with a __del__ method in models or
controllers.

Even if you do not use web2py but use another framework, do not create
classes with __del__ methods if they may have self references, whether
or not you use exec.

Here is an example of a python program without exec that has the leak
we are talking about:

class Foo(object):
def __del__(self):
pass
while True:
foo = Foo()
foo.x = foo

[web2py] on a possible web2py memory leak

[Massimo Di Pierro]

Mitsuhiko on reddit brings up a good issue that I was not aware of: a
bug in exec.

code="""
class Foo(object):
def __del__(self):
pass
foo = Foo()
"""
while True: exec code in {}

causes a memory leak. Web2py does this. The memory leak is small in
practice and in fact nobody noticed it. Yet it is a concern, in
theory.

So far I have the current solution

code="""
class Foo(object):
def __del__(self):
pass
foo = Foo()
"""
import gc
while True:
exec code in {}
gc.collect()

It works for me and I cannot reproduce the leak.
I patched trunk with this. Give it a try and let me know what you
think.

Right now it doesn't split an application across domains. If that's useful, I 
could extend the syntax. There's an alternative syntax to the one I showed 
earlier, where the domain map is defined globally in the BASE router. While 
it's not currently a feature, it would look like this:

routers = dict(
BASE = dict(
domains = {
"example1.com" : "app1/controller1",
"example1.net" : "app1/controller2"
},
)
)

Guido released a new DataStore API for GAE

I read the docs and I think this syntax looks like DAL syntax

*Look the NewDataStoreAPI syntax:*
msg = yield Greeting.get_or_insert_async('hello', message='Hello world')

Let's break this up further into its constituents:

f = Greeting.get_or_insert_async('hello', message='Hello world')

msg = yield f

BTW, The old API will remain intact and working.

Re: [web2py] Re: ADVOCACY: "every single other Python program ever written uses imports"?

[Michele Comitini]

I think the most misunderstood fact with web2py is that web2py
implementation is improving every day,
because of TOP-DOWN approach choosen by Massimo.
What does that mean? If someone finds that something has big impact
on perfomace, web2py gets changed to better and the users can upgrade
safely, because
the external simple API of the framework does not change.
So critics are welcome, the more the better.

"exec ccode in " is not injection? It is IoC for sure.
http://en.wikipedia.org/wiki/Inversion_of_control

 where is it deprecated? I cannot read it.
http://docs.python.org/reference/simple_stmts.html#the-exec-statement


remove "exec ... in ..." from python? On what basis? if you want a
static language go out of python. I wonder what GVR thinks about that.

The only good reasons at the moment to change that are:
1) exec statement bug
2) drastic performance improvement

Neither is true AFAIK, but maybe web2py's IoC will change, for testing
and debugging purposes, this is free (not as a beer) software indeed,
so a  new solution would be adopted if one comes with a better one
instead of talking about plain aesthetics, which is a good thing
although it is not alway viable in this world.  But if that would
happen fear not, we won't notice, we will not have to change our code.

I'd ideally like to see an all web2py solution too, but I agree that 
it's a big task, which I suspect some underestimate.


As a long-time Plone user (specifically, integrating RDBMS applications 
with Plone CMSs), I'm actually very happy using Plone as a CMS and 
web2py for RDBMS apps, and integrating the two where I need to.


There is another issue, which is "dilution" - Plone has somewhat 
eclipsed Zope, and there is debate on and off about whether Plone is a 
CMS application or a framework, while Zope is now sometimes described as 
a CMS. I think that confusion has had a cost for both Zope and Plone.


My hope is that: -

- Web2py keeps focussing on being an excellent framework.

- If someone develops a heavyweight CMS in web2py, which would be good, 
it does not get confused with web2py itself.


FWIW, I'm hoping to start publishing my web2py notes later this month, 
and have been a little bit concerned that I might get a negative 
reaction to their being in a Plone CMS. I'm going to stop worrying about 
that - I've picked the best framework for my work in web2py, and the 
best CMS for me to document it in Plone.

Don't compare instantpress with another big cms, I developed instant press
in 3 month myself, plus learning web2py. How much develop and programmers
have wordpress? :P. I started to learn web2py and what can I do with the
framework. Yes is need it a lot of time to make it instantpress big.

I2p is a CMS, with little minimal modification, you can have it. Take a look
to http://www.hospedajelacima.com.ar is made it with instant press and is
not a blog. A very simple site that fit very well with i2p objective.

I planned some modification to the next version of i2p, that is going to
make it more like a CMS. I am going to integrate more with web2py theme also
the next version will have the admin separated of the i2p layout, plus
hierarchy to articles.

Hi Philip,

Web2py is to me the next generation of MS Access, and I mean that as a

I'm  database developer (going back to DataEase for DOS and FoxPro, and 
the IBM S/26) in need of a data-driven front end, and I see web2py as 
the perfect tool for me. I have no desire to tinker /inside/ web2py - I 
just want to use it to develop apps.


Rather than competing with Django /et al/, which are defined as much by 
a culture as the technology, I'd like to see some advocacy to promote 
web2py to people who simply aren't in a position to use Django, but who 
can get up to speed with web2py very easily.


The comment earlier about Massimo's approach being informed by his 
teaching experience seemed very sharp to me.



For really, big complex apps, there may be some reason that Django is
preferable - I'll leave that to the professional web developers to
figure out the tools they need - but I can't say enough about how
great my experience has been with web2py, as a non-developer looking
for the "tools that in the easiest manner facilitate the creation of
what I want to do" (to use your words).  I just needed to get stuff
done, and web2py worked.



Just so.

[web2py] Re: Drupal alternatives in Python or web2py

[pbreit]

I think it would definitely be worthwhile for there to be a decent 
Web2py-based CMS. But it doesn't need to be as extensive and complicated as 
Drupal. Keep it simple.

By way of a little more explanation: 'default' doesn't appear because 'default' 
is already the default controller. There's a router named BASE for overrides 
that apply to all apps, but it's left out here because it's empty. The defaults 
are shown in router.example.py.

[web2py] web2py book

[puercoespin]

Is there an errata file of the printed book? Because Lulu's book has
many errors, and I have to be in comparison to the online version of
it.

 I also think it would be interesting that users can add comments in
the book, and that anyone can also display, as is for example in the
postgresql manual. To this end, the online version should be more
structured and divided, so that comments can be made in sections, not
whole chapters.

In my opinion, a great book (not good, but great) is very important
for the prestige of web2py framework and for more people to
incorporate it as part of their technical background.

I just want to second this point.  I fit this description.  I'm a
business guy, and no part of my job description would mention setting
up databases or writing software, but often software is a way to
increase efficiency dramatically, even if it's just a VB script in
Excel to automate some repetitive or complex task. I recognized that
my team would benefit a lot if we had a gold copy of certain data in a
database accessible to everyone (with normal CRUD features and some
canned ways of presenting it).  In the past, I would have thrown
together a MS Access DB, but I realized that a web-based app would be
far better, and that the web frameworks out there would make that
equally as easy to put together.  I took some CS classes in college
(15 years ago) and wrote a decent amount of code back then (Fortran,
Lisp, C) but had never used Python nor had I ever done any web-related
development (heck, I even had to brush up on HTML!) before deciding to
set this up.
After looking around at frameworks (with the most time spent on Django
including some initial app prototyping), I chose web2py.  It was a no-
brainer, because it was very easy to get started with, and yet as far
as I can tell, there is nothing that I cannot do in web2py that I
could do, or could do easier, in any other framework. I taught myself
Python to use web2py, and I put together an app that we now use in
production in our firm.  It was a nights and weekends project, and it
took longer than it should have because of my inexperience, but in the
grand scheme of things it took very little effort relative to the
value it created.

Web2py is to me the next generation of MS Access, and I mean that as a
compliment.  MS Access first opened up the world of database-driven
applications to business people.  With Access they could throw
together a simple application to manage a database (CRUD and reports)
without having to hire a developer or wait on their IT staff to write

I'd like to see a good CMS based on web2py (the analogy isn't exact, but sort

Tks for your opinions.

So I take it that it may not be worthwhile to consider building a
drupal-like CMS off web2py for non-programmers?

[web2py] Re: Drupal alternatives in Python or web2py

[VP]

In essence, a CMS is not really a framework.  Just like a forum
software, or a blog software is not a CMS.  I think unless VBulletin
or Wordpress drastic changes their structure, they will not be as
capable as Drupal, as a CMS.

A CMS is a platform to build systems that manage content.  It happens
to be the the core of most web app are about managing contents.  This
is why Drupal is very popular and powerful.   But as you add features
on top of your apps that have little to do with the management of
content, you will find it difficult in Drupal.

A framework is more general.  With web2py (or perhaps other
frameworks) you can relatively easily build something like a Stock
Exchange App.  With Drupal, you probably can too, but it will be more
difficult, and you'll have to piggy back lots of unnecessary things
that have to do with CMS.

Drupal is very nice at what it is.  But because of that I think it's
very dangerous.  Most web apps have some form of management of
content.   This makes it very tempting to quickly adopt something like
Drupal.  But as you add on top of that core behavior other things, it
will bite you in the butt.   But for 80% of web apps, Drupal does very
well.

Looking at web2py, we already have an IDE, a wizard, and a plugin
wiki. Might be the beginnings of a drupal-like CMS for this year's
web2py exhibition.

I'd say it's pretty much true of the major CMS's out there (it's certainly true 
of Expression Engine), but it may not be because of the nature of CMS's 
generally. I think it might be possible to write a good one. Difficult, though, 
especially at the definition/architecture stage. It's too easy to leave 
necessary functionality out, and too easy to screw things up by patching it in 
later.

Re: [web2py] Re: ADVOCACY: "every single other Python program ever written uses imports"?

[Bruno Rocha]

After being offended by web2py being in Pycon, they made a major
attack on reddit, raised a bunch of lies. Alarmed against web2py on
twitter (they managed to enter to the top tweets) and
this created a certain discomfort.

Some of my clients (two of them) called me asking for explanations about it.
(Interestingly, after my explanation they seem much more confident)

Moreover two new possible new clients came to me today (one by
experts4solutions), one of them commented about the topic and the tweets, so
it awakened interest to evaluate web2py to a new small project.

A company that offers online training came to me asking me to submit a
web2py training to their program,  they think web2py is trendy and many
people are talking about it on the web, then it is a good
time to offer training.

thanks to @jacob, @armin, @GrahamDumpleton and @benbangert and others. They

Exactly right. I've removed a few of those, but it's tedious work.

I've been using pyflakes as a quick check on my Python coding. Pyflakes is very 
handy, but it's also fairly simpleminded. If you say "from gluon.tools import 
*", it doesn't look in gluon.tools to see what that might mean; it just turns 
off its search for undefined symbols. So to get its benefit, you have to fix 
the import *.

For the same reason, a lot of my code starts out with:

if False:
import request, response, session, T, (etc)

OTOH, pyflakes has built-in knowledge of built-in Python globals.

One of the things that the web2py-imports discussion tends to miss, though, is 
that the web2py "globals" exist precisely because they're *not* globals--they 
have request scope, not global scope. They can't be imported (in a 
straightforward way, anyway), and it would be a PITA to have to pass them 
around everywhere. That would have been an alternative strategy for web2py: 
every argument list starts with the request-global, which would include all 
that stuff.

[web2py] Re: wrong documentation on ajax api sample?

[DenesL]

Hmmm... somewhere after 1.56.2 the ajax function was changed.
It now uses serialize (which encodes a set of form elements as a
string for submission) instead of the original getElementById.

You're right, it's not worth spending energy to try to convince these 
particular individuals -- they've all got vested interests (personal or 
professional) in alternatives. However, lots of disinterested folks are also 
reading those reddit threads, so sometimes it's worth correcting the record

[web2py] wrong documentation on ajax api sample?

[kuokon]

hello,

from the document
 (page 423 of 3rd edition of web2py, and 
http://web2py.com/book/default/chapter/10)

it say the ajax api has the following signature
   

however, when I tried on my own application, instead of the 'id'
field, I need to use the 'name' field
   

in order for the ajax api to work. (ie, the input tag has to be 'name'
instead of 'id')

maybe the document was wrong or the API get changed recently?
I'm using the most recent (web2py-1.91.5) web2py.

[web2py] Output literal '{{' and '}}' in template

[hcvst]

Hi,

I'm using a jQuery template plugin that also uses '{{' and '}}' as
markers.  I need to output something like  in the
rendered HTML. I'm now using this but is there a better way?

{{=XML(u'')}}

Thanks,
HC

Forgot to mention the admin interface and the ability to compile and package 
an application in a couple of button presses into a single file and then 
deploy to the production servers.

The ticketing system instead of come look at my screen, it broke. My users 
are in locations up to 3000 miles away and have essentially zero computer 
skills beyond using a browser, email and other basics.

[web2py] Re: web2py-related thread at reddit

[ron_m]

It is unfortunate that these things occur and hopefully people are going to 
be serious developers on a framework are smart enough to do their own 
evaluation.

I came to Python about 1.5 years ago mainly because I was doing video 
processing with gstreamer and the best control language for that is Python 
unless you want to work in C/C++ with no performance advantage because the 
heavy lifting is already going on in the gstreamer library coded mostly in 
C.

I needed to add a web site to work with the underlying application for 
general user access and while I was doing the above work I spent a lot of 
time on the various Python web framework web sites. I had already done 
extensive web work in Java and PHP, each to his own but I didn't like the 
prospects of working with either of those any more. I found most of the 
usual suspects including web2py in less than an hour and spent time reading 
the news groups etc. I saw these negative comments before, looked at the 
other frameworks but kept coming back to web2py. I made the commitment to 
use web2py sometime last summer.

Why? 

Because it was incredibly self contained but still could be extended easily. 
The others looked like a collection of libraries put together.

Because of the simplicity of defining a model in the DAL and the nice flow 
of request to response through controllers and views. 

In a pragmattic sort of way it all seemed to just fit together and work 
without an impedance mismatch to what I am trying to achieve. It required 
essentially nothing in boilerplate code. There is this small set of objects 
you work with to complete the server side workings of a web request, use 
them to do what you need, move on to next request. I see web2py as a nice 
abstraction layer that handles all the complicated details for you that 
requires the least amount of work on my part. Some call it magic, I call it 
something I don't have to worry about.

The dedication of the leader of the project Massimo and the responsiveness 
to problems and enhancements.

The commitment to backward compatibility.

The good, helpful and friendly attitude of the community.

Actually, I'm using the route.py script that Massimo provided a while
ago.  But a more understandable configuration is preferable. Here it
is (routes.conf is not listed here):

default_function = 'v'

try: config=open('routes.conf','r').read()
except: config=''

def auto_in(apps):
routes=[
('/robots.txt','/welcome/static/robots.txt'),
('/admin$anything','/admin$anything'),
]
for a,b in [x.strip().split() for x in apps.split('\n') if
x.strip() and not x.strip().startswith('#')]:
if not b.startswith('/'): b='/'+b
if b.endswith('/'): b=b[:-1]
app = b.split('/')[1]
routes+=[
('.*:https?://(www\.)?%s:$method /' % a,'%s' % b),
('.*:https?://(www\.)?%s:$method /$anything' % a,'%s/
$anything' % b),
('.*:https?://(.*\.)?%s:$method /static/$anything' % a,'%s/
static/$anything' % app),
('.*:https?://(.*\.)?%s:$method /appadmin/$anything' %
a,'%s/appadmin/$anything' % app),
]
return routes



default_function = 'v'

try: config=open('routes.conf','r').read()
except: config=''

def auto_in(apps):
routes=[
('/robots.txt','/welcome/static/robots.txt'),
('/admin$anything','/admin$anything'),

[web2py] Re: Drupal alternatives in Python or web2py

[VP]

It's not so much PHP (at least not directly).

It's a Trojan horse because it's a very attractive tool to create
something quick, easy and pretty.  CCK (now included in core), Panel,
Views are so powerful that you can create many websites (apps) with
them.  But as you go deeper, trying to add features, it will be so
difficult.  Just to make the app looks right to your taste is really a
challenging job.

Another thing that is not so obvious to beginners is performance.  It
will baffle you how many database queries are made just to show a page
(Drupal 6, but 7 is probably the same).  Caching is good, but sometime
you can't cache everything.

Essentially, there are so much thing in the package that you have to
piggy back for your app.  Things like web2py are much more tidy. You
have a global views of where things are.  But Drupal is huge.

well that's my point of view.

[web2py] Re: ADVOCACY: "every single other Python program ever written uses imports"?

[VP]

Jacobian made a few bogus statements.  One is about imports.

In fact, you don't need to import anything to use Python globals or
primitive data structures.  Why?  because those primitives structures
are so useful and often used that they are automatically imported for
use.

This is conceptually similar about the Web2py primitives.  These
primitives are so often used that there are automatically imported.

Another bogus statement is about web2py is harder to learn.  Now.
Jacob is a very smart guy with proven records.  But he doesn't have a
record of being a teacher, one that Massimo has.  I think it is this
experience that Massimo understands better what it is easy or
difficult for beginners to learn.  Personally, I have two Django books
in my bookshelf, but I eventually gave up Django to look for other
options that did waste my time.   A little more objective, if people
pay attention to the tweets, there are lots of beginners who love
web2py and find it so easy to learn.



The most outrageous thing that comes out of Jacob and some other folks
is this mentality that "Python experts will look down to you if you
use web2py" or "sure, beginners love web2py because they are
beginners".   These guys seem to have no clue about the increasingly
pervasive nature of computing in society today.  There are many very
smart and intelligent "beginners" who know little about web frameworks
or even Python.  They simply look for tools to develop their ideas.
In fact, you see many scientists and researchers who write programs
and develop webapps (in particular).  My thinking is in the short
future many more (smart) people who will be writing programs,
naturally.  They will look for tools that in the easiest manner
facilitate the creation of what they want to do.

It is very unfortunately that these young and smart guys are trapped
in their narrow world.  So much group-think.  So narrow-minded.

My advice again is simply to ignore them.  As I said in a previous
post, as long as you mention Flask, Django in the same breath as
web2py, it's going to be a negative experience.

Excessive desire to see all import statements comes from (OCD) fear.
Fear leads to hate.  Hate leads to the dark side :)

My 2c is that guys like Jacobian are really, really scared of web2py,
and want to kill it now before it grows bigger.  Otherwise, they
wouldn't go out of their way to write these huge posts about it.

Drupal is a Trojan horse.  Don't go there.
