2 years ago It seems that Python 3.10.5 has some change which is related to this (I still haven't investigated, but I can see that it worked in 3.10.0 and is failing in 3.10.5).

2 years ago Ouch, that sounds painful. Sorry for pointing this out; if I knew how to address it, I would certainly help :(

2 years ago I tried the latest version of PyDev.Debugger (commit 40a1c78a07c2a74e9a0da03433b3ad63d9c78c12) which includes the commit 1813bbd65cbe1382aae9d4851ad4bf14b55be1de which I understand was intended to fix this issue. Unfortunately it still doesn't work with Python 3.10.5:

========================= 1 failed, 1 warning in 0.17s =========================[EDIT: Oops; I accidentally used the system's pytest rather than the venv one; rerunning with python -m pytest gave the same results, though.]

2 years ago Ah, these two tests now work; clearly the patch has either been updated or something else has changed to make it work. Closing this issue. Thanks!!

Hi! Using the latest GitHub sources (https://github.com/fabioz/PyDev.Debugger/commit/1b1fb8b8a8d1c1068fecf2e28890a2e764eade71) and running the package tests with Python 3.10 (on a Debian system using a virtual environment, set up as in the GitHub workflows file in the package) gives two failing tests; these pass with Python 3.9, so presumably there is some Python bytecode format change involved. The two failing tests are:
In both cases, the error is that the baseline does not match the contents.
Best wishes, Julian
