Pdb y trytond-console

Support Developer
1

Buenos días

Quisiera consultar si es posible usar pdb en trytond-console. Si introduzco un breakpoint() o import pdb; pdb.set_strace() me sale una excepción:

[3] > (19)()
(Pdb++)
Traceback (most recent call last):
File “”, line 19, in 
File “”, line 19, in 
File “/usr/lib/python3.7/bdb.py”, line 88, in trace_dispatch
return self.dispatch_line(frame)
File “/usr/lib/python3.7/bdb.py”, line 113, in dispatch_line
if self.quitting: raise BdbQuit
bdb.BdbQuit

Si necesito correr scripts en el servidor en combinación con el cron de Linux, suelo usar Proteus, me pregunto para que se debería usar o en qué casos trytond-console?

En caso de elegir trytond-console ¿ hay alguna manera de hacer debug que no sea usar prints?

Muchas gracias!

Luis

It is not currently possible.

We have this patch applied to allow that, but it would be great if it made it into core.

Hi!
I assume this patch is for a more recent version of Tryton, and I’m using 6.0. Based on the code you shared, I manually adapted it to version 6.0. I also made some modifications so that pdbpp (a drop-in replacement for pdb) doesn’t throw errors when using the “sticky” and “ll” features.

It will be great if somebody contributes the change so it can be included in newer tryton series.
