[web2py] sqlform form.accept bug? I am confused
Hi all,
I am still a newbie to web2py so could be that this is my fault.
I am making a warehouse stock registry app. At present I try to make a
procedure where the worker can input the new received gadgets. The
form have quantity field. If it is greater than 1, I need to do
additional inserts to the db with the same data (the id will be
different of course).
The current situation that the form and the controller works, but not
always and I can't find the reasons. In the most of the cases when I
visit the page for the first time, fill in the fields and submit,
usually I get back the page without any errors, but no insert made on
the database. I see that the form.accept is false, but form.errors is
empty. If I fill in the form again it usually accepts and makes the
inserts, but also not always sometimes it never accepts does not
matter how many times I try.
On the other hand, if I make a validation error at will, and I get the
error messages of the validation, and then I input the correct datas
it usually accepts (sometimes not but that is rare).
I suppose that this behavor comes from a web2py feature, e.g caching
or the preventing of booking the same form times due to user error. It
is also could happen that I misunderstood something related to forms.
Can somebody help me to solve this issue?
Here is the related function in the controller (konyveles.py). I
insert several objects to the returned dict to check their content in
the view for debug purposes:
def beerkeztetes():
form=SQLFORM(db.eszkozok,

faccept=form.accepts(request.vars)

response.flash = '%s db új eszköz felvéve' % darab

[web2py] Re: sqlform form.accept bug? I am confused
additional info: I keep trying to find the reasons :) I realized that after the failed submit the form gets a new hidden input with name=_formname and value=eszkozok_create, but the old field datas are resetted to defaults. When this hidden field exists the form.accept is OK. How can I make sqlform to create this hidden field for the first visit also?
[web2py] Re: no json - cont.
The problem is that not everything is json and rss serializable. What
does your action look like?
a controller has a function called get_companies()
The companies table was chosen because it is readable as flat, for
learning..
(interested in .html .json and then perhaps .csv)
def get_companies():
rows = db().select(
db.companies.ALL,
orderby=db.companies.company_short_name)
return dict(rows=rows, description='description')
##-
I *do* use dates, but surprisingly, there are none here...
db.define_table('companies',
Field('pkey', type='integer'),
Field('company_full_name', type='text'),
Field('company_short_name', type='text'),
Field('net_sales', type='integer'),
primarykey=['pkey'],
migrate=migrate)
##---
so I am not sure what is not serializable about companies
as a beginner, it does look like there is some room for improvement
here..
.html .json .xml etc is a powerful facility. would be great to be
bulletproofed!
[web2py] Re: no json - cont.
@jonathan: Yes, a more detailed error messages than no json would be
awesome.
generic.json now says:
{{
###
# response._vars contains the dictionary returned by the controller action
###
try:
from gluon.serializers import json
response.write(json(response._vars),escape=False)
response.headers['Content-Type']='text/json'
except:
raise HTTP(405,'no json')
}}
I suggest this instead:
{{
###
# response._vars contains the dictionary returned by the controller action

try:
from gluon.serializers import json
response.write(json(response._vars), escape=False)
response.headers['Content-Type'] = 'application/json'
except (TypeError, ValueError):
raise HTTP(405, 'JSON serialization error')
except ImportError:

except:

}}
I patched that in, and changed the last one to say

raise HTTP(405, 'JSON error: ' + str(E))
and got in my case
JSON error: 'id'

Problem solved. form.accept didn't reached if request.vars were empty so it could not create the hidden fields. I've moved it out from the if block and everything is ok now.

[web2py] Programmatically Build Table in View
I have begun to move from models, modules, and controllers into actually
writing the view for my application. Now, I am at the point where I need to
loop through a Rows object, building a TR for each row. I wrote a version
that works by writing it in HTML, using {{=x}} where needed, but it looks
all cluttered and difficult to read. This is the original code that works:
{{extend 'layout.html'}}
h1Time Clock for {{=user.first_name}} {{=user.last_name}}/h1
{{if len(rows) 0:}}
{{
def get_day_of_year(the_date):
return the_date.timetuple().tm_yday
def full_date_name(the_date):
return the_date.strftime('%A, %B %d, %Y')
def time_string(the_date):
return the_date.strftime('%I:%M %p')
prev_day_of_year = None
table_open = False
for row in rows:
if get_day_of_year(row.calculated_start) != prev_day_of_year:}}
{{if table_open:}}
/tbody/table
{{pass}}
h4{{=full_date_name(row.calculated_start)}}/h4
tabletheadtrthTime in:/ththTime
out:/th/tr/theadtbody
trtd{{=time_string(row.calculated_start)}}/tdtd{{=time_string(row.calculated_end)}}/td/tr
{{table_open = True}}
{{prev_day_of_year = get_day_of_year(row.calculated_start)}}
{{else:}}
trtd{{=time_string(row.calculated_start)}}/tdtd{{=time_string(row.calculated_end)}}/td/tr
{{pass}}
{{pass}}
/tbody/table
h5Total hours worked this week: {{=hours_worked}}/h5
{{else:}}
h5No time clock entries for this week./h5
{{pass}}
I know that web2py has HTML helpers like TABLE(), TR(), etc, but how would I
build a table in this way, while in a for loop? This is what I tried so far,
but it fails so horribly I don't even know where the error is:
{{extend 'layout.html'}}
h1Time Clock for {{=user.first_name}} {{=user.last_name}}/h1

prev_day_of_year = None
tables = []
trs = None
for row in rows:
if get_day_of_year(row.calculated_start) != prev_day_of_year:
if trs is not None:
tables[] = (H4(full_date_name(row.calculated_start)),
trs)
trs = []

else:
trs[] = TR((TD(time_string(row.calculated_start)),
TD(time_string(row.calculated_end
for table in tables:
response.write(table[0])
response.write(TABLE(

Ah. Let's find out a little more. I suggest two experiments.
The easier one: include E.__class__.__name__ in the string, so we can see
what's being raised.
Then I'd like to see if we can force a ticket. Try changing the last raise to:
raise SyntaxError, and if you get a stack trace, let's see where the exception
is coming from.
When I took a look through the code, it looked to me like serialization errors
were all causing Type or Value exceptions, but I might have missed something.
[web2py] Re: Testing accions that access the database.
I have been playing with this somewhat myself. if you use doctests and run them via the admin interface then request.function == '_TEST'. you can use that in db.py to set a different db connection string. if the population of this db is quick you can do it in the doctest itself, or come up with a way to pre-populate it. I'm still working on different ways to pre-populate my test database, and don't have anything very clean right now. good luck! christian

I usually try to put less logic in my views. For one, I try to assemble all
the data fields ahead of time either in the controller or with virtual
fields.
Then in the view, I try to just end up looping through the dict. I normally
use HTML tags but using Web2py tag helpers should be fine as well.
See example below. Notice that I have a sliver of logic in there to display
no results if there are no items. Also note that I have a couple fields
like item.last_date that I have generated as a virtual field. In this way,
you keep your views looking mostly like regular pages of HTML with some
logic here and there.

Re: [web2py] Re: Programmatically Build Table in View
That was a very helpful example. Thank you. So using the web2py TABLE helpers
is best used for creating simple, static tables where the rows aren't
generated? I guess that's ok, I always thought that the controller was meant to
get the data, while the views format the data. But if the web2py way is to
format in the controller and make the views contain as little Python code as
possible, then that's they way I'll write it.

use HTML tags but using Web2py tag helpers should be fine as well.
See example below. Notice that I have a sliver of logic in there to display
no results if there are no items. Also note that I have a couple fields
like item.last_date that I have generated as a virtual field. In this way,
you keep your views looking mostly like regular pages of HTML with some logic
here and there.

Re: [web2py] Re: Programmatically Build Table in View
Well, I wouldn't necessarily say that's the web2py way. I just like to keep the logic in my views minimal. For example, the virtual fields are actually in the models which is also a good place to prepare your data. One reason to limit logic in views is if you ever have graphic designers working on your views which is common in larger projects. Some people like to have their code generate all of the HTML. I tend to prefer making it look like HTML with limited substitutions via code.

I would think it'd at least be possible to edit the code directly if not subclass/override it? Is that a problem because other components depend on its default behavior?

On Thursday, March 3, 2011 11:44:41 AM UTC-5, Ross Peoples wrote: That was a very helpful example. Thank you. So using the web2py TABLE helpers is best used for creating simple, static tables where the rows aren't generated? I think you should be able to build a table programmatically using helpers. See the TABLE, TR, TD section here: http://www.web2py.com/book/default/chapter/05#Built-in-Helpers (shows an example using a list comprehension). I guess that's ok, I always thought that the controller was meant to get the data, while the views format the data. That's probably the right way to think about it (from an MVC perspective), though I suppose what it means for the view to get the data can be a judgment call. You have to decide how you want to structure the data before passing it to the view for presentation. In your case, it looks like you've got a single set of rows, which you are then breaking into multiple tables -- so you have to ask yourself whether it makes sense for the controller (business logic) to decide how to break up the rows into separate tables, or whether that's purely a presentation issue. If the former, then maybe create a data structure that breaks up the rows in the controller, and have the view simply build the table for each set of rows returned by the controller. You might also think about what you would want the controller to return in case its output was going to a different view (e.g., JSON) -- if you need to structure the data differently depending on the view, then it might make sense to do the structuring in the view rather than the controller.

[web2py] FYI jQuery 1.5.1 breaks jQueryUI buttonsets
The latest web2py trunk jQuery is 1.5.1 If using a buttonset from the jQueryUI Button widget the Javascript trips on the label tag 'for' attribute and throws an error leaving the buttonset as a set of radio boxes instead of making them into buttons. This can be seen in the jQueryUI Button Toolbar demo as an example (http://jqueryui.com/demos/button/). I haven't figured it out yet and I am not discouraging web2py from moving forward to 1.5.1, I am just mentioning this to document it. I can keep my application at jQuery 1.4.4 until this is fixed by the jQuery/jQueryUI group.
[web2py] Losing session vars
My fledgling app is driving users crazy. I use the session to store a
list of strings, and then use prev and next controllers to
redirect to a page by indexing into that list. Ever since I enabled
this feature, users randomly lose their auth and are forced to re-
logon. This blows away the list and index and forces them to restart
the sequence.
I've read all about session vars and how they need to be serialized.
The list is a simple Python list of either ints or strings (I've tried
both). I also store the current index pointer into the list, again as
either a string or int. The effect is completely random -- sometimes
it will let you next or prev without complaint and then *bam*
suddenly it forces you to re-logon with every click of next or
prev.
Here is the string version of next:
def event_next():
if session.eventlist and (int(session.eventptr)=0):
tmp=int(session.eventptr)+1
if tmp=len(session.eventlist):
tmp=0
session.eventptr=str(tmp)
redirect(URL('meet','signup',args=[int(session.eventlist[tmp])]))
session.flash=Lost sync with events!
redirect(URL('meet','index'))
Is there a better way? These session vars are driving me crazy!

[web2py] Re: Losing session vars
Is eventlist constant for the application? If so put it in the model or if in a module use local_import. Then all you need in session is the current index into the array the user is at. If eventlist changes then there is no code showing how it is manipulated so it difficult to help. I would also believe that a variable eventlist would be difficult to debug. On the redirect call above I am not sure why you are converting session.eventlist[tmp] to an int. It might be converted back to a str by the URL function but for sure it ultimately ends up as part of a larger string to form the full URL. Finally are users opening the application more than once from the same client PC? If so the same browser tabs/windows will all use the same session. Also not sure if this is a problem but are the users behind a NAT box (typical of small office and home routers) and the server is elsewhere because this will put all the PCs behind the NAT at the same client IP which I believe causes sessions to be shared.

Re: [web2py] Re: Programmatically Build Table in View
And furthering my example, in that very same view I have another table that
displays the same set of items in grid format. Note I included a counter i

columns. Also note the logic that inserts a placeholder image if an image is
not present.
So it's not that there is no logic in the view, it's just keeping it sort of
minimal. Also, I expect to move the styles into css files at some point.

[web2py] Re: Losing session vars
Hi Ron -- The eventlist is populated by a database query that returns the ids of a set of objects. The prev and next page flips thru the database ids one at a time and allows adding objects through the database entry. It's a little complicated. The application is a signup app for a high-school swim meet, and each database id represents one event. At each event, users (coaches) are allowed to add records that represent swimmers signing up for that event. I don't believe it matters how the eventlist is created -- it's just a Python list object containing strings or integers (not at the same time -- I tried each to see if it affects the session var). It is established once when the coach clicks on the meet he wants to sign up for, and then does not change until he chooses another meet. The problem is that the user gets logged off sometimes when next or prev is clicked. My guess is that something in the session variable is not pickleable and is causing the session read-back to fail, thus forcing the re-logon and loss of the session vars. But I've been careful to not add anything but simple Python objects to session vars. (At least that I can find!) -- Joe B. P.S. Good tip on the URL and int. I just converted from using ints to strings and didn't think thru the URL function. You're probably right -- I'll bet it converts to str when it emits which will save me the int call.

Note that you also do not need to use TD objects specifically (unless
you want to add class, etc.) TR will take multiple args and wrap each
with a TD automatically.

[web2py] Re: Error in trunk opening PostgreSQL database
Additional information:
I added a print to the front end of DAL.__init__ and was surprised to find
driver_args was set to {'check_same_thread': False} but I did not set it in
my db = DAL() class constructor call.
So here is the issue. I start up the development environment on Linux with a
terminal command python web2py.py sitting in the correct web2py directory.
Because I have Tcl/TK installed on the system it comes up, solicits an admin
password and then I start the server.
This in turn brings up a browser window running the welcome application. The
welcome application as written uses SQLLite as the database and since it is
default installed in Python = 2.5 I have the driver and a connection
succeeds. The SQLLite adapter does use this driver_args parameter and if it
is not set forces it to the value I am seeing.
Somehow driver_args gets stored globally and becomes the default for all
other adapter calls to __init__ on any other driver as well.
To test this theory I commented out the db=DAL(...) line in db.py in the
welcome application and restarted the server. This caused the welcome app to
crash during the TclTk solicited start of the welcome app when the browser
is opened but at least the DAL did not get initialized using the SQLLite
database.
Now I am able to run my own application and the driver_args = {} which would
be correct for the PostgreSQL adapter.
Hope that helps isolate it a little better.

[web2py] Re: Deleting a cookie
Hey there, Dane.
I ran in to this same problem, needing to delete a cookie. Just
wanted to let you know the solution that worked for me was to ALSO set
the path just as you would when you were setting the cookie.
For instance:
- Setting the cookie:
response.cookies['test_cookie'] = 'valid'
response.cookies['test_cookie']['expires'] = 3600
response.cookies['test_cookie']['path'] = '/'
- Delete cookie
response.cookies['test_cookie'] = 'invalid'
response.cookies['test_cookie']['expires'] = -10
response.cookies['test_cookie']['path'] = '/'
Works for me. Let me know if you have any luck.
Hope that helps!

You cannot directlydeleteacookieon a user's computer. However,
you can direct the user's browser todeletethecookieby setting the

Am I missing something here? Where are you building a table -- I don't see
any calls to TABLE(), just TR(). Also, I'm not sure about your syntax. It
looks like you are passing a tuple of TD's to TR instead of passing the TD's
as separate arguments (i.e., there's an extra set of parentheses inside TR).
Finally, what is 'trs[] =' doing -- I think that will raise a syntax error.
You should be able to create a table object (e.g., table = TABLE()), and
then append TR's to it via append -- e.g., table.append(TR('cell 1', 'cell
2')).

Re: [web2py] Re: Programmatically Build Table in View
After seeing all the other posts, I completely rewrote the whole thing. I
grouped the data in the controller so that entries on the same day will be in
the same list, making easier to put each day of entries into its own table. I
have really advanced the whole thing since my original post. Here is my
controller:

if hours == 0:
return 00:%02d % (minutes)
else:
minutes -= minutes * hours
return %02d:%02d % (hours, minutes)

week_start, week_end = timeclock.get_week_range_for_date()
rows = timeclock.list_for_user(auth.user, week_start, week_end)
minutes_worked = timeclock.get_minutes_for_this_week(auth.user)
minutes_vacation = timeclock.get_minutes_for_this_week(auth.user, 2)
minutes_personal = timeclock.get_minutes_for_this_week(auth.user, 3)
minutes_sick = timeclock.get_minutes_for_this_week(auth.user, 4)
minutes_total = minutes_worked + minutes_vacation + minutes_personal +
minutes_sick
# begin formatting minutes for the week
hours_worked = format_minutes(minutes_worked)
hours_vacation = format_minutes(minutes_vacation)
hours_personal = format_minutes(minutes_personal)
hours_sick = format_minutes(minutes_sick)
hours_total = format_minutes(minutes_total)
# group entries together to make it easier for the view
grouped_entries = dict()
for row in rows:
full_date = format_full_date(row.calculated_start)
if full_date in grouped_entries:
grouped_entries[full_date].append(row)
else:
grouped_entries[full_date] = [row]
return dict(grouped_entries=grouped_entries,
hours_worked=hours_worked, hours_vacation=hours_vacation,
hours_personal=hours_personal, hours_sick=hours_sick,

Yeah, I got kind of lost, too. The thing that threw me off were trs[] = and tables[] =. The = sign is for assignment, not adding or appending.

Re: [web2py] Re: Programmatically Build Table in View
Yea, for some reason I thought that 'tables[] = ' would append to the list. I'm not sure which language that's from, but it doesn't matter now, as it is certainly much more readable to me.

I am used to running from the command line on Linux when in development mode and so starting with rocket as the web server as in python web2py.py from the command line I can just add print statements in the controller to try and follow what is going on. print response.session_id, other_variables_as_needed

[web2py] Re: Programmatically Build Table in View
hey,
here is what I do with plugin_wiki (usually for automated reports, but
here is a simplified sample):
header = ['First_Name', 'Last_Name', 'Age', 'Description']
data = \
'''fred,Flintstone,32,always gets into trouble,
Barney,Rubble,33,is always willing to help Fred
Mr,Slate,31,good businees man but not a people person
Dino,dinosaur,3,looks like he should be a dog
Pebbles,Flintstone,2,Great kid but does not talk much'''
if isinstance(data,str):
rows = [row.strip().split(',') for row in data.splitlines()]
if header is not None:
nHeader = []
for h in header:
nHeader.append('**{0}**'.format(h))
markminTable = table_lists2Markmin([nHeader] + rows)
else:
markminTable = table_lists2Markmin([header] + rows)
print markminTable
# here is the function that makes a markmin table (sorry if the
formatting looks bad here):
def table_lists2Markmin(rows):
tableRows = deque()
for tRows in [([[sStr for sStr in item] for item in map(None,
*[item.split('\n') for item in row])]) for
row in rows]:
for tableRow in tRows:
tableRows.append('{0}'.format(' |
'.join([string.join(string.strip(item),
'')
for item in tableRow])))
return '---\n{0}\n---'.format(string.join(tableRows,'\n'))
Usually the string data (it can be a list or a table as well) gets
passed to a function that will make use (not shown here be it has too
many lines) of anything we have in markmin by doing something like
below.
data = \
'''fred,Flintstone,32,always gets into trouble,
Barney,Rubble,33,is always willing to help Fred
Mr,Slate,31,good business man and this is his {0}
Dino,dinosaur,3,looks like he should be a dog
Pebbles,Flintstone,2,Great kid but does not talk much
'''.format(mmObj.mLink('favorite link','http:/www.google.com'))
makes automating Markmin tables easy through automation and decorating
the fileds as well.
hope it helps,
Mart :)

Actually, I think that simply raises a syntax error.
I think
trs[:] = something

I cannot reproduce this. Which web2py version? Which browser?

Hi,
Boolean fields are automatically toggling in forms when validation fails.
(model)
db.define_table('xxx', Field('xstring',requires=IS_NOT_EMPTY()),
Field('xboolean','boolean'))
(controller)
def xxx(): return dict(form=crud.create(db.xxx))
(url)
http://localhost:8000/test/default/xxx
When form is initially loaded, the boolean field is OFF, but after hitting
submit (with a failed validation, e.g. xstring empty), it automatically
toggles its value to ON, then hit submit again and it toggles to OFF, and so
on.
This occurs in both: creates and updates.
Is this a bug?.

[web2py] Re: Error in trunk opening PostgreSQL database
Wow that fixed it. You are a Python Ninja :-)
I would sure like to know what the mechanism was that caused driver_args to
bleed from SQLLite to the other adapters even though it is defaulted it to
an empty dict on the class initializer. I also printed driver_args as the
first line of code in DAL.__init__() and it had the value left over from
SQLLite so how driver_args or {} produces {} when there is a value in
driver_args.
But you are very busy so if you don't have time no problem.
[web2py] Re: Error in trunk opening PostgreSQL database
class DAL:
def __init__(self,...,driver_args={})
so because this is defined in a module, every time driver_args is not
passed it is set to {}, the same {}. If one app changes, the default
changes for all apps. It is kind of counter intuitive but it works
that way.
It is very dangerous to set a default in a function to a list of
dictionary, because if somewhere downstream the object changed for one
instance, it changes the default for all future instances.

This is the default behavior for the new router: hyphens in the URL for a/c/f
become underscores internally. You can turn it off if you want. BTW, you don't
need the admin router; it was an artifact of doctesting, and is gone in the
trunk. Try this (everything else you had set is the default):
routers = dict(
BASE = dict(
map_hyphen = False, # don't map hyphens to underscores
),
)

That was my thinking. Underscores in URLs are ugly. The mapping applies only to a/c/f, since they generally need to be Python identifiers. Static file paths and args are never mapped.

I see what you mean, it could cause a little confusion if people think it is referring to the table.

I patched that in, and changed the last one to say

Ah. Let's find out a little more. I suggest two experiments.
The easier one: include E.__class__.__name__ in the string, so we can see
what's being raised.
Then I'd like to see if we can force a ticket. Try changing the last raise
to: raise SyntaxError, and if you get a stack trace, let's see where the
exception is coming from.
When I took a look through the code, it looked to me like serialization
errors were all causing Type or Value exceptions, but I might have missed
something.
ok, in order
E.__class__.__name__ = KeyError
then, substituting SyntaxError does indeed create a stack trace

I am, however, having a hard time identifying export_to_csv( ) either in views/appadmin.html or appadmin.py. While import_from_csv is clearly called from within appadmin.import_csv, I am unable to identify how export_to_csv is called there. The export is done by the csv() function in appadmin.py: http://code.google.com/p/web2py/source/browse/applications/welcome/controllers/appadmin.py#142 That function returns: str(db(query).select()) The db(query).select() is a DAL Rows object, and since it is passed to str(), the __str__ method of the Rows class is applied. You can see the __str__ method of the Rows class in dal.py here: http://code.google.com/p/web2py/source/browse/gluon/dal.py#4850 http://code.google.com/p/web2py/source/browse/gluon/dal.py#4850As As you can see, the __str__ method ultimately calls the export_to_csv_file method, which is here: http://code.google.com/p/web2py/source/browse/gluon/dal.py#4947 I suppose you could write your own export_tab_delimited function that works like __str__ but passes delimiter='\t' to export_to_csv_file. Maybe something like this added to appadmin.py: import cStringIO def export_tab_delimited(rows): s = cStringIO.StringIO() rows.export_to_csv_file(s, delimiter='\t') return s.getvalue() And then change the last line of the csv() function to: return export_tab_delimited(db(query).select()) Anthony

Why it happens with json and not xml I have no idea, but the xml encoding logic is significantly different from the json code.
[web2py] potential memory leak???
My app has utilized much RAM over time, so I created a simple app to
replicate the problem. This is what I found out.
First of all, the app:
++ Model (database is postgres):
db.define_table('data',
Field('body','text',requires=IS_LENGTH(262144)),
Field('body1','text',requires=IS_LENGTH(262144)),
Field('body2','text',requires=IS_LENGTH(262144)),
Field('body3','text',requires=IS_LENGTH(262144)))
### I populate the database with about 1500 entries
#from gluon.contrib.populate import populate
#populate(db.data,100)
++ Controller:
def index():
return dict( data = db().select(db.data.ALL) )
++ View/default/index.html:
{{extend 'layout.html'}}
{{i=1}}
{{ for d in data: }}
{{=i}}. {{=d.body}} {{=d.body1}} {{=d.body2}} {{=d.body3}}.
{{i+=1}}
{{ pass }}
==
Apache configuration: 5 processes, 1 thread (more than 1 threads
will cause WSGI premature script error as previously described).
==
Result (this is with 1.92.1; 1.91.6 had same problem)
A fresh apache restart gives each of 5 processes about 43MB.
After using ab to stress test with 20 connections, 10 seconds,
repeated several times, RAM starts crawling up to about 130MB per
process.
The RAM appears to be stuck there at 130MB/process and not released.
At this point the RAM per process does not get increased with repeated
testing... BUT Apache starts getting this error:
IOError: failed to write data
mod_wsgi (pid=12689): Exception occurred processing WSGI script '/home/
vphan/web2py/wsgihandler.py'.
==
This is with the simple app above. With my real app, RAM keeps
getting increased and not released.
It seems that if I load many rows (each with much data) into memory,
we see this problem.
Does the DAL leak memory?
