Release Date: 2018-09-04 // over 5 years ago

  • Thanks

    Thanks to the following projects which we fully rely on to provide some of our features:

    Also thanks to the various projects we provide integrations with which help 👉 make this extension useful:

    And finally thanks to the Python development team and community for creating a fantastic programming language and community to be a part of!

    ✨ Enhancements

    1. Improved language server startup time by 40%. (#1865) 👍 1. Add pip dependency support to the conda environment.yml YAML schema support (thanks Mark Edwards). (#2119) 🌐 1. Added a German translation. (thanks to bschley and by means of berndverst and croth1 for the reviews) (#2203)
    2. The new setting python.analysis.diagnosticPublishDelay allows you to control when language server publishes diagnostics. Default is 1 second after the user activity, such a typing, ceases. If diagnostic is clear (i.e. errors got fixed), the publishing is immediate. (#2270) 👍 1. Language server now supports hierarchical document outline per language server protocol 4.4+ and VS Code 1.26+. (#2384)
    3. Make use of the http.proxy field in settings.json when downloading the Python Language Server. (#2385)

    🛠 Fixes

    1. Fix debugger issue that prevented users from copying the value of a variable from the Variables debugger window. (#1398) ✅ 1. Enable code lenses for tests when using the new language server. (#1948) 👻 1. Fix null reference exception in the language server causing server initialization to fail. The exception happened when search paths contained a folder that did not exist. (#2017)
    2. Language server now populates document outline with all symbols instead of just top-level ones. (#2050) ✅ 1. Ensure test count values in the status bar represent the correct number of tests that were discovered and run. (#2143) 📚 1. Fixed issue in the language server when documentation for a function always produced "Documentation is still being calculated, please try again soon". (#2179) 👕 1. Change linter message parsing so it respects python.linting.maxNumberOfProblems. (thanks Scott Saponas) (#2198) 🛠 1. Fixed language server issue when it could enter infinite loop reloading modules. (#2207)
    3. Ensure workspace pipenv environment is not labeled as a virtual env. (#2223)
    4. Improve reliability of document outline population with language server. (#2224)
    5. Language server now correctly handles with statement when __enter__ is declared in a base class. (#2240)
    6. Fix visualstudio_py_testLauncher to stop breaking out of test discovery too soon. (#2241) 👍 1. Notify the user when the language server does not support their platform. (#2245) 🏁 1. Fix issue with survey not opening in a browser for Windows users. (#2252)
    7. Correct banner survey question text to reference the Python Language Server. (#2253) 🛠 1. Fixed issue in the language server when typing dot under certain conditions produced null reference exception. (#2262)
    8. Fix error when switching from new language server to the old Jedi language server. (#2281) ⬆️ 1. Unpin Pylint from < 2.0 (prospector was upgraded and isn't stuck on that any longer) (#2284) 👍 1. Add support for breaking into the first line of code in the new debugger. (#2299)
    9. Show the debugger survey banner for only a subset of users. (#2300) 🔧 1. Ensure Flask debug configuration launches flask in a debug environment with the Flask debug mode disabled. This is necessary to ensure the custom debugger takes precedence over the interactive debugger, and live reloading is disabled. http://flask.pocoo.org/docs/1.0/api/#flask.Flask.debug (#2309) 🔀 1. Language server now correctly merges data from typeshed and the Python library. (#2345) ✅ 1. Fix pytest >= 3.7 test discovery. (#2347) ⚡️ 1. Update the downloaded Python language server nuget package filename to Python-Language-Server-{OSType}.beta.nupkg. (#2362) 0️⃣ 1. Added setting to control language server log output. Default is now 'error' so there should be much less noise in the output. (#2405)
    10. Fix experimental debugger when debugging Python files with Unicode characters in the file path. (#688)
    11. Ensure stepping out of debugged code does not take user into PTVSD debugger code. (#767) ⬆️ 1. Upgrade pythonExperimental to python in launch.json. (#2478)

    Code Health

    ⏪ 1. Revert change that moved IExperimentalDebuggerBanner into a common location. (#2195)

    1. Decorate EventEmitter within a try..catch to play nice with other extensions performing the same operation. (#2196) 0️⃣ 1. Change the default interpreter to favor Python 3 over Python 2. (#2266) 🏗 1. Deprecate command Python: Build Workspace Symbols when using the language server. (#2267) 👕 1. Pin version of pylint to 3.6.3 to allow ensure pylint gets installed on Travis with Python2.7. (#2305) 🚚 1. Remove some of the debugger tests and fix some minor debugger issues. (#2307) 🚀 1. Only use the current stable version of PTVSD in CI builds/releases. (#2432)
