[issue42383] Pdb does not correclty restart the target if it changes the current directory
New submission from Andrey Bienkowski :
This was mentioned in #31121, but I believe this deserves its own separate
issue. If the debug target is specified using a relative path and later the
current directory is changed, pdb tries to search for the target in the new
current directory. This currently causes pdb to be unable to exit, which is
what #31121 and #14743 are about, but even if they are fixed we would still be
left with pdb exiting instead of restarting the target. This issues is about
the latter.
To reproduce (same as #31121):
$ mkdir foo
$ cat > foo/script.py
import os
os.chdir('foo')
$ python3 -m pdb foo/script.py
> /home/user/foo/script.py(1)()
-> import os
(Pdb) c
The program finished and will be restarted
Traceback (most recent call last):
File "/usr/lib64/python3.8/pdb.py", line 1704, in main
pdb._runscript(mainpyfile)

[issue31121] Unable to exit pdb when script becomes invalid
Andrey Bienkowski added the comment: Another way to reproduce this that will continue to work once #42383 is fixed is to delete or move the script while it's being debugged. -- nosy: +hexagonrecursion ___ Python tracker <https://bugs.python.org/issue31121> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue42384] Inconsistent sys.path between python and pdb
New submission from Andrey Bienkowski : The first entry in sys.path is different between `python foo.py` and `python -m pdb foo.py`. In the former it is the absolute path to the parent directory of foo.py while in the later it is a relative path (unless the debug target was specified using an absolute path). The meaning of the absolute path does not change when the current directory changes (e.g. via os.chdir()) while the meaning of the relative path does. Like any environment inconsistency between regular program execution and the debugger this may lead to bugs that mysteriously vanish when you try to debug them. $ cat > print-path.py import sys from pprint import pprint pprint(sys.path) $ python3 print-path.py ['/home/user', '/usr/lib64/python38.zip', '/usr/lib64/python3.8', '/usr/lib64/python3.8/lib-dynload', '/usr/lib64/python3.8/site-packages', '/usr/lib/python3.8/site-packages'] $ python3 -m pdb print-path.py > /home/user/print-path.py(1)() -> import sys (Pdb) c ['', '/usr/lib64/python38.zip', '/usr/lib64/python3.8', '/usr/lib64/python3.8/lib-dynload', '/usr/lib64/python3.8/site-packages', '/usr/lib/python3.8/site-packages'] -- messages: 381215 nosy: hexagonrecursion priority: normal severity: normal status: open title: Inconsistent sys.path between python and pdb ___ Python tracker <https://bugs.python.org/issue42384> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue42387] Pdb should restore the execution environment before reexecuting the target
New submission from Andrey Bienkowski : When the target exits, pdb automatically restarts it. If the target changed something before exiting the changes will remain unless pdb explicitly undoes them. While working on #42383 I had an idea: it would be useful if pdb reverted the changes the target makes to the execution environment (to a reasonable extent) before restarting it. This includes: 1. os.getcwd() - currently not reverted 2. os.environ - I did not check if this is currently restored or not 3. sys.argv - --/-- 4. sys.path - --/-- -- components: Library (Lib) messages: 381225 nosy: hexagonrecursion priority: normal severity: normal status: open title: Pdb should restore the execution environment before reexecuting the target ___ Python tracker <https://bugs.python.org/issue42387> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
