f_lineno has different results on Windows and Linux #125422
Description
Bug report
Bug description:
On Windows 10, f_lineno is 1. On WSL (Ubuntu 20), it is 611. I don't see any mention of cross-platform differences called out in the bdb docs, so I'm wondering if this is a bug.
import bdb
f = {}
class areplDebug(bdb.Bdb):
# override
def user_line(self,frame):
global f
f = frame
b = areplDebug()
b.run('x=1+5',{},{})
print('frame lineno is ' + str(f.f_lineno)) # 611 on Linux, 1 on Windows
import linecache
line = linecache.getline(f.f_code.co_filename, f.f_lineno)
print('frame file is: ' + f.f_code.co_filename) # '/home/almenon/.pyenv/versions/3.12.7/lib/python3.12/bdb.py' on Linux, `<string>` on windows
print('frame line is: ' + line) # ' sys.settrace(None)\n' on Linux, None on WindowsIt's not a WSL-specific issue because I'm getting the same error in Github CI. See https://github.com/Almenon/AREPL-backend/actions/runs/11316437382/job/31468723754?pr=193
