Odoo.sh Editor on Jupyter : pdb.set_trace raises BdbQuit Error-CodePudding

Using my odoo.sh project (v13.0.2) > EDITOR-Tab , which redirects me to mywebsite.odoo.com/odoo-sh/editor/lab, when i want to debug using import pdb; pdb.set_trace(), it raises a BdbQuit Error :

  File "/usr/lib/python3.6/bdb.py", line 113, in 
  dispatch_exception
    if self.quitting: raise BdbQuit

In the past versions : v13.0.1.xxx, i could use pdb.set_trace() to debug my python code. How to solve this issue ?

CodePudding user response：

Using this post How to debug python CLI that takes stdin?, I have managed it this way :

in Odoo.sh>EDITOR (Jupyter Lab): Open a first Terminal and create these two fifos which will be used as stdin/stdout to use pdb :
```
 mkfifo fifo_stdin

 mkfifo fifo_stdout

 cat fifo_stdout & cat > fifo_stdin
```

...which makes appear a prompt cursor. Keep this Terminal Tab opened.

Write these 2 lines at the top of the Python script to be debugged :

 import pdb
 mypdb=pdb.Pdb(stdin=open('fifo_stdin','r'), stdout=open('fifo_stdout','w'))

In this Python script, call set_trace() on your customized mypdb using the 2 fifos

def _get_total_amount(self):     
   total_amount = sum(self._get_base_order_lines(program).mapped('price_total')) 
   mypdb.set_trace()  
   return total_amount

Open a second Terminal to launch your Odoo application :
```
odoo-bin -u sale_coupon --stop-after-init
```

...and wait till all modules get loaded

Switch to the first Terminal window (fifo)
In another Webbrowser-tab : Browse on your Odoo App / Website to trigger the function where you put your set_trace()
Go to the first Terminal and input function variables to be observed :
```
  total_amount
  1480.0
  (Pdb) 
```
Go further in your app process (next breakpoint if any) using "continue" and abort debugging using "quit"
```
  (Pdb) continue
  (Pdb) quit
```
Exit pdb using the keyboard combination : Ctrl D
Odoo could remain hanging, which required to comment the pdb-lines in the python script, close Terminal windows and relaunched your Odoo-App :

odoo-bin -u sale_coupon --stop-after-init
