bpo-43950: Add option to opt-out of PEP-657 by ammaraskar · Pull Request #27023 · python/cpython · GitHub

To be merged after #26958

This adds the opt-out option and disables the compiler's column information and traceback printing.

Btw, do we have a test that checks that the flag works?

Not yet :)

@pablogsal After making these changes, I am a little worried about the sys.flags.no_debug_ranges conditionals, I fear that without it being automatically tested somewhere we could end up with code-rot in the test suite. Would it be possible to run a buildbot with -X no_debug_ranges just to ensure that no bugs in the opted-out code paths pop up.

Would it be possible to run a buildbot with -X no_debug_ranges just to ensure that no bugs in the opted-out code paths pop up.

Hmmm, is possible, but I would prefer to explicitly test that the flag + env work in some specific tests using a subprocess and that would only left the skip() as conditional. Is true that that could break, but adding an entire buildbot is a bit of a big deal, although we can explore that.

Just added some, please take a look.

For example running test_traceback.py with the flag set? That would certainly work too, I like that approach.

The last remaining component for this PR is to make marshal.c replace the tables with None if the config option is set and test that.

Maybe we should do the logic in the code object constructor and that way we don't need to deal with marshal.c and the compiler.

Great idea, did this in the common code path in codeobject.c :)
That makes the code a lot simpler.

Added tests to make sure de-marshaling with the flag results in None for the endlinetable and columntable.

Going back to this, do you know if there is an example of such a test that already exists in the suite? Where should it go? A new test_traceback_no_debug_range.py or similar?

We need more rebasing :(

buildbot/AMD64 Ubuntu Shared PR has a weird failure...

/srv/buildbot/buildarea/pull_request.bolen-ubuntu/build/python: error while loading shared libraries: libpython3.11d.so.1.0: cannot open shared object file: No such file or directory

I wonder if we need a @requires_* on it or if it's just a buildbot problem?

Nope, no @requires annotation is needed to use assert_python_ok and assert_python_failure. This seems to just be a problem with the buildbot.

@pablogsal all lights are green, anything else for this one?

Nop. Great job! 👌

@ammaraskar @isidentical Hummm, have we bumped the magic number? This buildbot failure seems quite related. I'm in some meetings right now and cannot check but may need to revert:(

AFAIK we did. Checking the failures now...

stderr:
---
ld-elf.so.1: Shared object "libpython3.11d.so.1.0" not found, required by "python"
---

when running assert_python_ok and assert_python_failure and both buildbots have "Shared" in the name.

The confusing thing is, it only happens with the new tests, existing assert_python_ok tests are working just fine.

To reproduce locally;

$ git clean -fxd
$ ./configure --with-pydebug --enable-shared -C
$ make -j
$ LD_LIBRARY_PATH=$PWD ./python -m test -v test_traceback

We don't preserve the original environment, so shared builds fail. See here:

cpython/Lib/test/support/script_helper.py

Lines 117 to 121 in bb3e0c2

    
           else: 
        
               # Need to preserve the original environment, for in-place testing of 
        
               # shared library builds. 
        
               env = os.environ.copy()

I can confirm that setting __cleanenv to False fixes the issue

Aah, let's remove __cleanenv in that case. I set it primarily because I thought it would avoid propagation of the testing Interpreter's config.

Also see this example usage of how it is used (it creates a new env based on the existing one) if you want to isolate these;

    def get_hash(self, repr_, seed=None):
        env = os.environ.copy()
        env['__cleanenv'] = True  # signal to assert_python not to do a copy
                                  # of os.environ on its own
        if seed is not None:
            env['PYTHONHASHSEED'] = str(seed)
        else:
            env.pop('PYTHONHASHSEED', None)
        out = assert_python_ok(
            '-c', self.get_hash_command(repr_),
            **env)
        stdout = out[1].strip()
        return int(stdout)
