The repro steps say that the distro is Anaconda - are you rebuilding that from source, or is that actually the official CPython interpreter? Or is it some kind of mix?

Also, can you try this with debugpy? See microsoft/ptvsd#2104 for instructions.

The reference to Anaconda was just from the bug report template. This is a generic python source build.

From the crash, it seems that it's crashing inside of qt/sip... my current guess is that it's some incompatibility in your CPython version and qt.

Have you checked if it runs properly without the debugger?

I'm sorry, that was a bad example. This crashes when debugging a file with only one line like "print('here')". here is a better crash report that shows the crash in attach_x86_64.dylib

Oh, are you using attach-by-PID? If so, it's not entirely surprising that it doesn't work with a custom interpreter, depending on how exactly it was customized - it needs to access many Python internals, so changes to layout of built-in Python types (PyObject etc) break it.

patrickkidd · 2020-04-27T17:42:27Z

I am using ”request”: “launch” in launch.json. Everything works just fine with “request”: “attach” if that’s what you are asking about.

Or are you talking about some additional option in ”request”: “launch”? Or something else entirely?

fabioz · 2020-04-27T17:48:26Z

Actually, we may use that library without the attach (to set the tracing to different threads as Python can only set the tracing to the current thread).

You can try to recompile it locally to see if it fixes your problem. To do that, you can run:

debugpy/_vendored/pydevd/pydevd_attach_to_process/linux_and_mac/compile_mac.sh

I'm confused. Is this for some python package other than ptvsd?

int19h · 2020-04-27T17:53:33Z

Actually, we may use that library without the attach

But then the same caveat applies to "launch" as well - we do not support CPython builds that aren't ABI-compatible with stock CPython, basically. If it has any changes to structs in Python headers, or if compilation flags that affect type layout differ from platform defaults (e.g. --enable-unicode / Py_UNICODE_SIZE)

int19h · 2020-04-27T17:54:54Z

@patrickkidd This is for debugpy, which is basically the next version of ptvsd: microsoft/ptvsd#2104

Please give it a try, as it contains a more recent version of pydevd, with more fixes in it.

patrickkidd · 2020-04-27T17:56:27Z

Ah ok. I am new to all of this. I will check out debugpy. As for ABI compatibility, I am using a generic python build with no configure options.

@int19h maybe we could have a flag not to do that (we just use it to set tracing to different threads in that context, so, it could be optional -- in fact, it doesn't work for PyPy, but we check for the cases where we know we can support it, but we don't take into account custom builds where using it can crash the interpreter).

@patrickkidd, until we actually make that optional, another option could be changing def load_python_helper_lib(): in debugpy/_vendored/pydevd/pydevd_tracing.py to always return None.

patrickkidd · 2020-04-27T18:07:55Z

debugpy/_vendored/pydevd/pydevd_attach_to_process/linux_and_mac/compile_mac.sh

I'm sorry, I'm a little lost here. After following the instructions at microsoft/ptvsd#2104, I found compile_mac.sh in ~/.vscode/extensions/ms-python.python-2020.5.76036-dev/pythonFiles/lib/python/debugpy/no_wheels/debugpy/_vendored/pydevd/pydevd_attach_to_process/linux_and_mac/compile_mac.sh. Upon running it from the relative path you pasted, I get:

Is there some step I am missing for how to move from ptvsd to debugpy?

fabioz · 2020-04-27T18:14:12Z

You current working dir must be debugpy/_vendored/pydevd/pydevd_attach_to_process/linux_and_mac/ for it to work.

patrickkidd · 2020-04-27T21:19:37Z

I got the same error when in that folder.

I should add that the current ptvsd debugger was working quite well until about a month ago.

fabioz · 2020-04-28T10:33:50Z

That's weird, you mean that when you're in that directory and execute that .sh, it gives a no such file or directory: 'attach.cpp? (that's the first error, others are just noise afterwards) -- can you double check if attach.cpp is actually there?

patrickkidd · 2020-04-28T14:12:24Z

Yes, the file is there. I have no idea what's going on with this script. It looks simple enough but I'm getting strange output from it, for example bad spelling of English words and small errors in the characters of the output. I am running a standard macOS command line tools on the latest macOS. The only non-standard thing I am using is a homebred-installed bash b/c Catalina complains about deprecating its own bash in favor of zsh.

It looks like compile_mac.sh has DOS line endings. I changed them and now get undefined symbols:

It looks like this stuff is pre-alpha. is there a more stable way to approach simple python debugging with VS Code?

patrickkidd · 2020-04-29T21:18:23Z

Now just calling ptvsd.wait_for_attach() is immediately crashing at the same place. That was working fine yesterday. So now there is no way for me to debug python code at all! Removing the optinto entry from settings.json did not help. How can I reset everything to get back to a working system?? I'm dead in the water!

Building the debugger from source will probably work better if you do it from an enlistment, rather than trying to build the bundled copy. It can probably be made to build, but we never specifically arranged it to be buildable nor tested for it. This will also take care of newline issues.

If you're using ptvsd.enable_attach(), that means that you're running ptvsd rather than debugpy. To reiterate, ptvsd is not developed further, and it hasn't been developed for a while. We haven't made any changes to it since January, and that was in the 5.0 beta branch (that eventually became debugpy). If you're using the most recent stable version from PyPI, then you're running ptvsd 4.3.2, which shipped in August last year. So if ptvsd.enable_attach() is crashing for you, there are no recent changes that could cause it - if it only just started crashing now, then either something changed in the environment to enable it (e.g. the interpreter itself), or it is an inconsistent crash that has always been there, but just started to happen more consistently, e.g. due to some timing changes caused by the environment.

In general, please keep in mind that we don't support just any random Python interpreter - it would be too long of a list. We support official CPython builds from python.org, and OS-specific Python packages (Store on Windows, Brew on macOS, distro repos on Linux). If the same repro steps don't crash for you using stock prebuilt Python, you need to figure out how to build your custom interpreter such that it's ABI-compatible with stock builds.

That is very helpful, thanks for the clarification on those important points. I was able to isolate the problem. It only happens when python is built with —with-pydebug. Python version and OS doesn’t seem to matter. I have no idea why it started happening recently since I’ve been using debug builds for a few years. At any rate, any quick advice on how to retain ABI compatibility through a debug python build? I am using 3.7.2.

Ah, that explains it - --with-pydebug is very much ABI-breaking, because it #defines Py_TRACE_REFS among other things. That causes every PyObject to get two extra fields inserted at the very beginning, changing offsets of all the other fields in every Python object, including the refcount.

It's quite possible that this is the only thing about debug builds that makes a difference. If so, you can try to disable it by cherry-picking specific debug flags, as discussed in the special builds guide. Of note is that only Py_TRACE_REFS gets an ABI compatibility warning in that doc:

Note that because the fundamental PyObject layout changes, Python modules
compiled with Py_TRACE_REFS are incompatible with modules compiled without it.

So hopefully omitting that flag will do the trick, although of course that's also one of the more useful things about Python debug builds...

The reason why it might have worked before, and stopped working now, is that we use a bunch of native code to speed up the debugger, which is only compatible with some Python versions. So it's selectively enabled if a supported Python version is detected, but it falls back to pure Python otherwise. I suspect you were hitting the pure Python path before, and at some point either you upgraded to a newer version, or we added another optimization that affected the version you were using. As @fabioz noted above, you can try disabling those optimizations by editing the source code of the package:

until we actually make that optional, another option could be changing def load_python_helper_lib() in debugpy/_vendored/pydevd/pydevd_tracing.py to always return None.

On our side, it sounds like we should check for a debug build of Python (or maybe just Py_TRACE_REFS? it can be feature-tested via sys.getobjects()...), and disable native code optimizations in that case. I think it might also be useful to provide some way to explicitly opt out, as an escape hatch for custom builds or alternate implementations that we don't know how to detect. There are some features that inherently require native code - attach-to-PID, in particular - so I don't think we'll ever formally commit to fully supporting debug Python builds. But it sounds like we can make them work in practice in most common scenarios with little effort, which is worthwhile.

Note: I'm currently taking a look at this issue.

From what I searched, it seems that the best way to find out if it is a debug build is using:

hasattr(sys, 'gettotalrefcount')

i.e.: python itself seems to use that: https://github.com/python/cpython/blob/e3dfb9b967c560f4d094092dcae4a16fc9634681/Lib/test/pythoninfo.py#L128
