Hi,

Thank you. 

I was under the impression that web2py was only compatible with Python2.7, 
and that py4web was for Python3x.
I now understand that py2web has been modified and is also compatible with 
Python3, up to 3.11.

That definitely opens new horizons for me. I might try to install Python3 
alongside, and use it's venv.
I think that might be less confusing than trying to install a newer 
Python2.7 version, on this system, do you agree ?

Is migrating an web2py from Python2.7 to Python 3x a straightforward task ? 
Or might it need some code refactoring ?

I would say that >90% is straightforward.   Clean up all your "print" 
statements to "print()" calls, and that will get most of it.  There are a 
couple of other syntactical changes, but not very many.  Depending on your 
needs, though, there may be some standard library that is no longer 
standard library.  I encountered this around some special cases for needing 
to use urllib2.

Good luck!

Hello everyone,

I just migrated an old (2017-ish) web2py app, which was still hosted on a 
user machine, running on Rocket HTTP server.

The app is now on a CentOS 7 VM, under nginx/uwsgi using HTTPS.
Web2py version is 2.27.1, over Python 2.7.5, in a virtualenv.

All is OK as for the app itself, but now I as trying to setup cron to to 
delete old sessions, and I'm stuck with this :
*$ python web2py.py -S  -M -R scripts/sessions2trash.py -A -o -X 
3600 -f -v*
Traceback (most recent call last):
  File "web2py.py", line 44, in 
import gluon.widget
  File "/home/apinho/web2py/web2py/gluon/widget.py", line 28, in 
from gluon.console import console, is_appdir
  File "/home/apinho/web2py/web2py/gluon/console.py", line 53, in

  File "/home/apinho/web2py/web2py/gluon/shell.py", line 305
exec(read_pyc(pycfile), _env)
SyntaxError: unqualified exec is not allowed in function 'run' it contains 
a nested function with free variables

I really have no clue what to do. There is little help online. The only one 
I could find says that upgrading to Python 2.7.18 would do the trick, but 
that would most probably wreck Centos7 (Which I am stuck with, for it is my 
company's mandatory Linux distro for production environments).

Any help would be much appreciated.
Alexandre

[web2py] Re: 2.19.0 vs 2.27.1

Hello everybody.

I've actually some instances of web2py running with the 2.19.0 version.
0 problems, thank you web2py.

One of these is this one:
https://www.hydrover.it/ 

It uses the web2py grid, Bootstrap 2.3.2.

I must install a new web2py instance, where I'll copy the 
https://www.hydrover.it/  app, that'll be modified for fitting to another 
company.

Can I use the 2.27.1 without problems?

Thanks.



Backward compatibility is still quite good.  If you've already changed over 
to Python 3.x, you're probably in good shape.  Caveat:  I'm still on 
2.22.5., I use SQLFORM() rather than the grid, and haven't done much with 
the scheduler recently.

web2py is in maintenance mode.  Spiffing up the website  isn't an important 
sales tool.  Here's hoping py4web gets some new award badges as it takes 
over the world.
