New submission from STINNER Victor: Follow-up of the issue #26567 which added PyErr_ResourceWarning() (C API), attached patch adds a new source parameter to the warnings.warn() function (Python API).
source is the destroyed object which emits a ResourceWarning. The source is used to show the traceback where the object was created (allocated) when tracemalloc is used. The patch also changes _pyio, asyncio and asyncore modules to set the source parameter. Note: tempfile doesn't set source because it uses a class method: @classmethod def _cleanup(cls, name, warn_message): _shutil.rmtree(name) _warnings.warn(warn_message, ResourceWarning) ---------- files: warnings_warn_source.patch keywords: patch messages: 262137 nosy: haypo priority: normal severity: normal status: open title: Add optional source parameter to warnings.warn() type: enhancement versions: Python 3.6 Added file: http://bugs.python.org/file42236/warnings_warn_source.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26604> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
