AllanDaemon · DonJayamanne · commit bfcd2252f85c · 2018-09-25T14:56:51.000-07:00
Fixes #2380 The regex expression to match MyPy linter messages expects that the file name has a `.py` extension, that isn't always the case. E.g., `.pyi` files for describing interfaces. - [X] Title summarizes what is changing - [X] Includes a [news entry](https://github.com/Microsoft/vscode-python/tree/master/news) file (remember to thank yourself!) - [X] Unit tests & [code coverage](https://codecov.io/gh/Microsoft/vscode-python) are not adversely affected (within reason) - [X] Works on all [actively maintained versions of Python](https://devguide.python.org/#status-of-python-branches) (e.g. Python 2.7 & the latest Python 3 release) - [X] Works on Windows 10, macOS, and Linux (e.g. considered file system case-sensitivity) - [X] Dependencies are pinned (e.g. `"1.2.3"`, not `"^1.2.3"`) - [X] `package-lock.json` has been regenerated if dependencies have changed
