Subject: 24.3.92; pdb gud-print shows "Text is read only"
Date: Fri, 01 Aug 2014 21:19:09 -0300

While debugging a python script in python-mode (checkout of the latest
python.el) if the region contains, say, the name "v" of a python
variable, both C-x C-a C-p (in the python buffer) and C-c C-p (in the
gud buffer) just shows a "Text is read only" message at the
minibuffer. But executing "p v" in the gud buffer correctly shows the
value of the variable.

Thanks for the report.

I've tried reproducing this bug on the latest development branch and Emacs
26.2, but was unable to.

First, I have a file ~/foo.py with the following contents:

num = 200
print(num)

Next, I do this:

0. emacs -Q
1. M-x pdb RET pdb3 ~/foo.py RET

    Current directory is /home/skangas/
    > /home/skangas/foo.py(1)<module>()
    -> num = 200

2. Hit "n"

    (Pdb) n
    > /home/skangas/foo.py(2)<module>()
    -> print(num)

3. If I now do the step "C-x C-a C-p (in the python buffer) and C-c C-p (in
the
   > gud buffer)" (with point on the variable name), I see the following:

    num = 200
    num = 200
    (Pdb)

I don't see the message "Text is read only".

Are you still able to reproduce this bug on a recent version of Emacs?
If yes, could you please provide a recipe for how to reproduce it,
starting from "emacs -Q"?

If I don't hear back from you in a couple of weeks, I'll just assume
that the bug has been fixed in the years since you reported it and close
this bug report.

Best regards,
Stefan Kangas

No further information was given within 4 weeks, so I'm closing this
now.  If anyone can still reproduce this, please reopen the bug
report.
