OSX: JupyterLab debugger doesn’t work with xeus-python
Summary
When using xeus-python as the kernel, the JupyterLab debugger freezes as soon as a breakpoint is hit. The code pauses, but the debugger never updates — no variables, no stack, nothing. The UI becomes stuck until the kernel is interrupted.
https://github.com/user-attachments/assets/47fd1693-71ea-4c55-80fc-a261bc16e00c
Steps to Reproduce
- Open JupyterLab.
- Create a new notebook.
- Select xeus-python as the kernel.
- Open the Debugger panel.
- Click Enable Debugger.
- Add the following code in a cell
- Set a breakpoint on any line
- Execute the code cells
Code snippet for testing convenience
def inner(n):
if n <= 0:
return 0
return n + inner(n - 1)
def outer(n):
x = inner(n)
return x * 2
result = outer(3)
result
Can you check if the version of Python you have? If it is 3.13, can you test with 3.12 or 3.14?
The last time I had tested in python version 3.12, I can try with 3.13 and 3.14 and report accordingly
With python 3.13 i don't even see the debugger button enabled and i also see an error in the terminal

With python 3.14 I see the exact similar behaviour as shown in screencast in https://github.com/jupyter-xeus/xeus-python/issues/679#issue-3702152161
I cannot reproduce with latest xeus-python. How did you install it? If you installed it (or its dependencies) with micromamba, can you copy/paste the result of micromamba list ? Also, on which OS (and which version) do you have the issue?
I created environment and installed dependencies with mamba - here is the output of mamba list in my env:

"description": "|pypi_downloads| |codecov| |license|\n\n============\nIntroduction\n============\n\nThis library is mainly for CLI programs that carefully produce output for\nTerminals, or make pretend to be an emulator.\n\n**Problem Statement**: The printable length of *most* strings are equal to the\nnumber of cells they occupy on the screen ``1 character : 1 cell``. However,\nthere are categories of characters that *occupy 2 cells* (full-wide), and\nothers that *occupy 0* cells (zero-width).\n\n**Solution**: POSIX.1-2001 and POSIX.1-2008 conforming systems provide\n`wcwidth(3)`_ and `wcswidth(3)`_ C functions of which this python module's\nfunctions precisely copy. *These functions return the number of cells a\nunicode string is expected to occupy.*\n\nInstallation\n------------\n\nThe stable version of this package is maintained on pypi, install using pip::\n\n pip install wcwidth\n\nExample\n-------\n\n**Problem**: given the following phrase (Japanese),\n\n >>> text = u'コンニチハ'\n\nPython **incorrectly** uses the *string length* of 5 codepoints rather than the\n*printable length* of 10 cells, so that when using the `rjust` function, the\noutput length is wrong::\n\n >>> print(len('コンニチハ'))\n 5\n\n >>> print('コンニチハ'.rjust(20, '_'))\n _______________コンニチハ\n\nBy defining our own \"rjust\" function that uses wcwidth, we can correct this::\n\n >>> def wc_rjust(text, length, padding=' '):\n ... from wcwidth import wcswidth\n ... return padding * max(0, (length - wcswidth(text))) + text\n ...\n\nOur **Solution** uses wcswidth to determine the string length correctly::\n\n >>> from wcwidth import wcswidth\n >>> print(wcswidth('コンニチハ'))\n 10\n\n >>> print(wc_rjust('コンニチハ', 20, '_'))\n __________コンニチハ\n\n\nChoosing a Version\n------------------\n\nExport an environment variable, ``UNICODE_VERSION``. This should be done by\n*terminal emulators* or those developers experimenting with authoring one of\ntheir own, from shell::\n\n $ export UNICODE_VERSION=13.0\n\nIf unspecified, the latest version is used. If your Terminal Emulator does not\nexport this variable, you can use the `jquast/ucs-detect`_ utility to\nautomatically detect and export it to your shell.\n\nwcwidth, wcswidth\n-----------------\nUse function ``wcwidth()`` to determine the length of a *single unicode\ncharacter*, and ``wcswidth()`` to determine the length of many, a *string\nof unicode characters*.\n\nBriefly, return values of function ``wcwidth()`` are:\n\n``-1``\n Indeterminate (not printable).\n\n``0``\n Does not advance the cursor, such as NULL or Combining.\n\n``2``\n Characters of category East Asian Wide (W) or East Asian\n Full-width (F) which are displayed using two terminal cells.\n\n``1``\n All others.\n\nFunction ``wcswidth()`` simply returns the sum of all values for each character\nalong a string, or ``-1`` when it occurs anywhere along a string.\n\nFull API Documentation at https://wcwidth.readthedocs.io\n\n==========\nDeveloping\n==========\n\nInstall wcwidth in editable mode::\n\n pip install -e .\n\nExecute unit tests using tox_ for all supported Python versions::\n\n tox -e py36,py37,py38,py39,py310,py311,py312,py313,py314\n\nUpdating Unicode Version\n------------------------\n\nRegenerate python code tables from latest Unicode Specification data files::\n\n tox -e update\n\nThe script is located at ``bin/update-tables.py``, requires Python 3.9 or\nlater. It is recommended but not necessary to run this script with the newest\nPython, because the newest Python has the latest ``unicodedata`` for generating\ncomments.\n\nBuilding Documentation\n----------------------\n\nThis project is using `sphinx`_ 4.5 to build documentation::\n\n tox -e sphinx\n\nThe output will be in ``docs/_build/html/``.\n\nUpdating Requirements\n---------------------\n\nThis project is using `pip-tools`_ to manage requirements.\n\nTo upgrade requirements for updating unicode version, run::\n\n tox -e update_requirements_update\n\nTo upgrade requirements for testing, run::\n\n tox -e update_requirements37,update_requirements39\n\nTo upgrade requirements for building documentation, run::\n\n tox -e update_requirements_docs\n\nUtilities\n---------\n\nSupplementary tools for browsing and testing terminals for wide unicode\ncharacters are found in the `bin/`_ of this project's source code. Just ensure\nto first ``pip install -r requirements-develop.txt`` from this projects main\nfolder. For example, an interactive browser for testing::\n\n python ./bin/wcwidth-browser.py\n\n====\nUses\n====\n\nThis library is used in:\n\n- `jquast/blessed`_: a thin, practical wrapper around terminal capabilities in\n Python.\n\n- `prompt-toolkit/python-prompt-toolkit`_: a Library for building powerful\n interactive command lines in Python.\n\n- `dbcli/pgcli`_: Postgres CLI with autocompletion and syntax highlighting.\n\n- `thomasballinger/curtsies`_: a Curses-like terminal wrapper with a display\n based on compositing 2d arrays of text.\n\n- `selectel/pyte`_: Simple VTXXX-compatible linux terminal emulator.\n\n- `astanin/python-tabulate`_: Pretty-print tabular data in Python, a library\n and a command-line utility.\n\n- `rspeer/python-ftfy`_: Fixes mojibake and other glitches in Unicode\n text.\n\n- `nbedos/termtosvg`_: Terminal recorder that renders sessions as SVG\n animations.\n\n- `peterbrittain/asciimatics`_: Package to help people create full-screen text\n UIs.\n\n- `python-cmd2/cmd2`_: A tool for building interactive command line apps\n\n- `stratis-storage/stratis-cli`_: CLI for the Stratis project\n\n- `ihabunek/toot`_: A Mastodon CLI/TUI client\n\n- `saulpw/visidata`_: Terminal spreadsheet multitool for discovering and\n arranging data\n\n===============\nOther Languages\n===============\n\n- `timoxley/wcwidth`_: JavaScript\n- `janlelis/unicode-display_width`_: Ruby\n- `alecrabbit/php-wcwidth`_: PHP\n- `Text::CharWidth`_: Perl\n- `bluebear94/Terminal-WCWidth`_: Perl 6\n- `mattn/go-runewidth`_: Go\n- `grepsuzette/wcwidth`_: Haxe\n- `aperezdc/lua-wcwidth`_: Lua\n- `joachimschmidt557/zig-wcwidth`_: Zig\n- `fumiyas/wcwidth-cjk`_: `LD_PRELOAD` override\n- `joshuarubin/wcwidth9`_: Unicode version 9 in C\n\n=======\nHistory\n=======\n\n0.2.14 *2025-09-22*\n * **Drop Support** for Python 2.7 and 3.5. `PR #117`_.\n * **Update** tables to include Unicode Specifications 16.0.0 and 17.0.0.\n `PR #146`_.\n * **Bugfix** U+00AD SOFT HYPHEN should measure as 1, versions 0.2.9 through\n 0.2.13 measured as 0. `PR #149`_.\n\n0.2.13 *2024-01-06*\n * **Bugfix** zero-width support for Hangul Jamo (Korean)\n\n0.2.12 *2023-11-21*\n * re-release to remove .pyi file misplaced in wheel files `Issue #101`_.\n\n0.2.11 *2023-11-20*\n * Include tests files in the source distribution (`PR #98`_, `PR #100`_).\n\n0.2.10 *2023-11-13*\n * **Bugfix** accounting of some kinds of emoji sequences using U+FE0F\n Variation Selector 16 (`PR #97`_).\n * **Updated** `Specification <Specification_from_pypi_>`_.\n\n0.2.9 *2023-10-30*\n * **Bugfix** zero-width characters used in Emoji ZWJ sequences, Balinese,\n Jamo, Devanagari, Tamil, Kannada and others (`PR #91`_).\n * **Updated** to include `Specification <Specification_from_pypi_>`_ of\n character measurements.\n\n0.2.8 *2023-09-30*\n * Include requirements files in the source distribution (`PR #82`_).\n\n0.2.7 *2023-09-28*\n * **Updated** tables to include Unicode Specification 15.1.0.\n * Include ``bin``, ``docs``, and ``tox.ini`` in the source distribution\n\n0.2.6 *2023-01-14*\n * **Updated** tables to include Unicode Specification 14.0.0 and 15.0.0.\n * **Changed** developer tools to use pip-compile, and to use jinja2 templates\n for code generation in `bin/update-tables.py` to prepare for possible\n compiler optimization release.\n\n0.2.1 .. 0.2.5 *2020-06-23*\n * **Repository** changes to update tests and packaging issues, and\n begin tagging repository with matching release versions.\n\n0.2.0 *2020-06-01*\n * **Enhancement**: Unicode version may be selected by exporting the\n Environment variable ``UNICODE_VERSION``, such as ``13.0``, or ``6.3.0``.\n See the `jquast/ucs-detect`_ CLI utility for automatic detection.\n * **Enhancement**:\n API Documentation is published to readthedocs.io.\n * **Updated** tables for *all* Unicode Specifications with files\n published in a programmatically consumable format, versions 4.1.0\n through 13.0\n\n0.1.9 *2020-03-22*\n * **Performance** optimization by `Avram Lubkin`_, `PR #35`_.\n * **Updated** tables to Unicode Specification 13.0.0.\n\n0.1.8 *2020-01-01*\n * **Updated** tables to Unicode Specification 12.0.0.

python_version < \"3.11\"\n```\n\nThen, in your code, import a TOML parser using the following fallback mechanism:\n\n```python\nimport sys\n\nif sys.version_info >= (3, 11):\n import tomllib\nelse:\n import tomli as tomllib\n\ntomllib.loads(\"['This parses fine with Python 3.6+']\")\n```\n\n## FAQ<a name=\"faq\"></a>\n\n### Why this parser?<a name=\"why-this-parser\"></a>\n\n- it's lil'\n- pure Python with zero dependencies\n- the fastest pure Python parser [\\*](#pure-python):\n 18x as fast as [tomlkit](https://pypi.org/project/tomlkit/),\n 2.1x as fast as [toml](https://pypi.org/project/toml/)\n- outputs [basic data types](#how-do-toml-types-map-into-python-types) only\n- 100% spec compliant: passes all tests in\n [BurntSushi/toml-test](https://github.com/BurntSushi/toml-test)\n test suite\n- thoroughly tested: 100% branch coverage\n\n### Is comment preserving round-trip parsing supported?<a name=\"is-comment-preserving-round-trip-parsing-supported\"></a>\n\nNo.\n\nThe `tomli.loads` function returns a plain `dict` that is populated with builtin types and types from the standard library only.\nPreserving comments requires a custom type to be returned so will not be supported,\nat least not by the `tomli.loads` and `tomli.load` functions.\n\nLook into [TOML Kit](https://github.com/sdispater/tomlkit) if preservation of style is what you need.\n\n### Is there a `dumps`, `write` or `encode` function?<a name=\"is-there-a-dumps-write-or-encode-function\"></a>\n\n[Tomli-W](https://github.com/hukkin/tomli-w) is the write-only counterpart of Tomli, providing `dump` and `dumps` functions.\n\nThe core library does not include write capability, as most TOML use cases are read-only, and Tomli intends to be minimal.\n\n### How do TOML types map into Python types?<a name=\"how-do-toml-types-map-into-python-types\"></a>\n\n| TOML type | Python type | Details |\n| ---------------- | ------------------- | ------------------------------------------------------------ |\n| Document Root | `dict` | |\n| Key | `str` | |\n| String | `str` | |\n| Integer | `int` | |\n| Float | `float` | |\n| Boolean | `bool` | |\n| Offset Date-Time | `datetime.datetime` | `tzinfo` attribute set to an instance of `datetime.timezone` |\n| Local Date-Time | `datetime.datetime` | `tzinfo` attribute set to `None` |\n| Local Date | `datetime.date` | |\n| Local Time | `datetime.time` | |\n| Array | `list` | |\n| Table | `dict` | |\n| Inline Table | `dict` | |\n\n## Performance<a name=\"performance\"></a>\n\nThe `benchmark/` folder in this repository contains a performance benchmark for comparing the various Python TOML parsers.\n\nBelow are the results for commit [0724e2a](https://github.com/hukkin/tomli/tree/0724e2ab1858da7f5e05a9bffdb24c33589d951c).\n\n### Pure Python<a name=\"pure-python\"></a>\n\n```console\nfoo@bar:~/dev/tomli$ python --version\nPython 3.12.7\nfoo@bar:~/dev/tomli$ pip freeze\nattrs==21.4.0\nclick==8.1.7\npytomlpp==1.0.13\nqtoml==0.3.1\nrtoml==0.11.0\ntoml==0.10.2\ntomli @ file:///home/foo/dev/tomli\ntomlkit==0.13.2\nfoo@bar:~/dev/tomli$ python benchmark/run.py\nParsing data.toml 5000 times:\n------------------------------------------------------\n parser | exec time | performance (more is better)\n-----------+------------+-----------------------------\n rtoml | 0.647 s | baseline (100%)\n pytomlpp | 0.891 s | 72.62%\n tomli | 3.14 s | 20.56%\n toml | 6.69 s | 9.67%\n qtoml | 8.27 s | 7.82%\n tomlkit | 56.1 s | 1.15%\n```\n\n### Mypyc generated wheel<a name=\"mypyc-generated-wheel\"></a>\n\n```console\nfoo@bar:~/dev/tomli$ python benchmark/run.py\nParsing data.toml 5000 times:\n------------------------------------------------------\n parser | exec time | performance (more is better)\n-----------+------------+-----------------------------\n rtoml | 0.668 s | baseline (100%)\n pytomlpp | 0.893 s | 74.81%\n tomli | 1.96 s | 34.18%\n toml | 6.64 s | 10.07%\n qtoml | 8.26 s | 8.09%\n tomlkit | 52.9 s | 1.26%\n```\n\n",

It implements and updates the datetime type, plugging gaps in functionality and providing an intelligent module API that supports many common creation scenarios. Simply put, it helps you work with dates and times with fewer imports and a lot less code.\n\nArrow is named after the `arrow of time <https://en.wikipedia.org/wiki/Arrow_of_time>`_ and is heavily inspired by `moment.js <https://github.com/moment/moment>`_ and `requests <https://github.com/psf/requests>`_.\n\nWhy use Arrow over built-in modules?\n------------------------------------\n\nPython's standard library and some other low-level modules have near-complete date, time and timezone functionality, but don't work very well from a usability perspective:\n\n- Too many modules: datetime, time, calendar, dateutil, pytz and more\n- Too many types: date, time, datetime, tzinfo, timedelta, relativedelta, etc.\n- Timezones and timestamp conversions are verbose and unpleasant\n- Timezone naivety is the norm\n- Gaps in functionality: ISO 8601 parsing, timespans, humanization\n\nFeatures\n--------\n\n- Fully-implemented, drop-in replacement for datetime\n- Support for Python 3.8+\n- Timezone-aware and UTC by default\n- Super-simple creation options for many common input scenarios\n- ``shift`` method with support for relative offsets, including weeks\n- Format and parse strings automatically\n- Wide support for the `ISO 8601 <https://en.wikipedia.org/wiki/ISO_8601>`_ standard\n- Timezone conversion\n- Support for ``dateutil``, ``pytz``, and ``ZoneInfo`` tzinfo objects\n- Generates time spans, ranges, floors and ceilings for time frames ranging from microsecond to year\n- Humanize dates and times with a growing list of contributed locales\n- Extensible for your own Arrow-derived types\n- Full support for PEP 484-style type hints\n\nQuick Start\n-----------\n\nInstallation\n~~~~~~~~~~~~\n\nTo install Arrow, use `pip <https://pip.pypa.io/en/stable/quickstart/>`_ or `pipenv <https://docs.pipenv.org>`_:\n\n.. code-block:: console\n\n $ pip install -U arrow\n\nExample Usage\n~~~~~~~~~~~~~\n\n.. code-block:: python\n\n >>> import arrow\n >>> arrow.get('2013-05-11T21:23:58.970460+07:00')\n <Arrow [2013-05-11T21:23:58.970460+07:00]>\n\n >>> utc = arrow.utcnow()\n >>> utc\n <Arrow [2013-05-11T21:23:58.970460+00:00]>\n\n >>> utc = utc.shift(hours=-1)\n >>> utc\n <Arrow [2013-05-11T20:23:58.970460+00:00]>\n\n >>> local = utc.to('US/Pacific')\n >>> local\n <Arrow [2013-05-11T13:23:58.970460-07:00]>\n\n >>> local.timestamp()\n 1368303838.970460\n\n >>> local.format()\n '2013-05-11 13:23:58 -07:00'\n\n >>> local.format('YYYY-MM-DD HH:mm:ss ZZ')\n '2013-05-11 13:23:58 -07:00'\n\n >>> local.humanize()\n 'an hour ago'\n\n >>> local.humanize(locale='ko-kr')\n '한시간 전'\n\n.. end-inclusion-marker-do-not-remove\n\nDocumentation\n-------------\n\nFor full documentation, please visit `arrow.readthedocs.io <https://arrow.readthedocs.io>`_.\n\nContributing\n------------\n\nContributions are welcome for both code and localizations (adding and updating locales).

The annotations\nare returned as a dictionary. For classes, annotations include also\ninherited members.\n\nTypeError is raised if the argument is not of a type that can contain\nannotations, and an empty dictionary is returned if no annotations are\npresent.\n\nBEWARE -- the behavior of globalns and localns is counterintuitive\n(unless you are familiar with how eval() and exec() work). The\nsearch order is locals first, then globals.\n\n- If no dict arguments are passed, an attempt is made to use the\n globals from obj (or the respective module's globals for classes),\n and these are also used as the locals. If the object does not appear\n to have globals, an empty dictionary is used.\n\n- If one dict argument is passed, it is used for both globals and\n locals.\n\n- If two dict arguments are passed, they specify globals and\n locals, respectively.\n",

"description": "# PyZMQ: Python bindings for ØMQ\n\nThis package contains Python bindings for [ZeroMQ](https://zeromq.org).\nØMQ is a lightweight and fast messaging implementation.\n\nPyZMQ should work with any reasonable version of Python (≥ 3.8), as well as PyPy.\nPyZMQ supports libzmq ≥ 3.2.2 (including 4.x).\n\nFor a summary of changes to pyzmq, see our\n[changelog](https://pyzmq.readthedocs.io/en/latest/changelog.html).\n\n### ØMQ 3.x, 4.x\n\nPyZMQ fully supports the stable (not DRAFT) 3.x and 4.x APIs of libzmq,\ndeveloped at [zeromq/libzmq](https://github.com/zeromq/libzmq).\nNo code to change, no flags to pass,\njust build pyzmq against the latest and it should work.\n\n## Documentation\n\nSee PyZMQ's Sphinx-generated\ndocumentation [on Read the Docs](https://pyzmq.readthedocs.io) for API\ndetails, and some notes on Python and Cython development. If you want to\nlearn about using ØMQ in general, the excellent [ØMQ\nGuide](http://zguide.zeromq.org/py:all) is the place to start, which has a\nPython version of every example. We also have some information on our\n[wiki](https://github.com/zeromq/pyzmq/wiki).\n\n## Downloading\n\nUnless you specifically want to develop PyZMQ, we recommend downloading\nthe PyZMQ source code or wheels from\n[PyPI](https://pypi.io/project/pyzmq/),\nor install with conda.\n\nYou can also get the latest source code from our GitHub repository, but\nbuilding from the repository will require that you install recent Cython.\n\n## Building and installation\n\nFor more detail on building pyzmq, see [our docs](https://pyzmq.readthedocs.io/en/latest/howto/build.html).\n\nWe build wheels for macOS, Windows, and Linux, so you can get a binary on those platforms with:\n\n```\npip install pyzmq\n```\n\nbut compiling from source with `pip install pyzmq` should work in most environments.\nMake sure you are using the latest pip, or it may not find the right wheels.\n\nIf the wheel doesn't work for some reason, or you want to force pyzmq to be compiled\n(this is often preferable if you already have libzmq installed and configured the way you want it),\nyou can force installation from source with:\n\n```\npip install --no-binary=pyzmq pyzmq\n```\n\n## Old versions\n\npyzmq 16 drops support Python 2.6 and 3.2.\nIf you need to use one of those Python versions, you can pin your pyzmq version to before 16:\n\n```\npip install 'pyzmq<16'\n```\n\nFor libzmq 2.0.x, use 'pyzmq\\<2.1'\n\npyzmq-2.1.11 was the last version of pyzmq to support Python 2.5,\nand pyzmq ≥ 2.2.0 requires Python ≥ 2.6.\npyzmq-13.0.0 introduces PyPy support via CFFI, which only supports libzmq-3.2.2 and newer.\n\nPyZMQ releases ≤ 2.2.0 matched libzmq versioning, but this is no longer the case,\nstarting with PyZMQ 13.0.0 (it was the thirteenth release, so why not?).\nPyZMQ ≥ 13.0 follows semantic versioning conventions accounting only for PyZMQ itself.\n",

This can be used by applications that subclassed `NotebookApp` to leverage the Python server backend of Jupyter Notebooks. Such extensions should *now* switch to `ExtensionApp` API in Jupyter Server and add `NotebookConfigShimMixin` in their inheritance list to properly handle moved traits.\n\nFor example, an application class that previously looked like:\n\n```python\nfrom notebook.notebookapp import NotebookApp\n\nclass MyApplication(NotebookApp):\n```\n\nshould switch to look something like:\n\n```python\nfrom jupyter_server.extension.application import ExtensionApp\nfrom notebook_shim.shim import NotebookConfigShimMixin\n\nclass MyApplication(NotebookConfigShimMixin, ExtensionApp):\n```",

Hi,
I gave this an attempt with @arjxn-py and yes I could reproduce this. Initially with latest jupyterlab, xeus-python (from conda-forge) and python 3.14 the debugger freezes as the breakpoint hits.
But after going through this comment, we lowered to python 3.12 and jupyterlab 4.4.7 (which was the version released when the above pr went in). Using this configuration we observed a couple working attempts where the debugger was working but overall it was all flaky (because restarting the kernel and executing the same again got us back to the same issue)
Also note : We enabled debugger tests through this PR and as can be seen here all of them pass on main. Which tells me that this might not be a xeus-python issue ?!
Do you have the same issue with ipykernel?
No, it is working fine with ipykernel.
