Python puts the working directory first on sys.path for -c / -m. venv creation, pip (list/install/uninstall), the library-path probe and the IDE-managed Python tool probes and installs inherited the IDE's own working directory, so a project's typing.py / logging.py there broke them ("partially initialized module 'typing'"). venv creation now runs python -I; pip, the library probe and the tool commands run in an empty private directory (keeping pip install --user packages visible), and relative requirements (., ./pkg, .[dev]) resolve against the project root. The window-label part of the original change already landed in #960.

OpenIDEA brings the IntelliJ IDEA way of working — its keymap, its tool windows, its search-everything habits — to a native app with a Rust core.
Editor, code insight, debugger, Git, terminal, database and HTTP clients, for 60+ languages. Builds for macOS, Windows and Linux.
Benchmark
Opening freqtrade (Python, ~770 files) with warm caches, median of 5 runs:
| OpenIDEA | IntelliJ IDEA 2026.2.3 | |
|---|---|---|
| Window with the project | 0.9 s | 3.1 s |
| Ready (CPU settled) | 1.1 s | 13.2 s |
| Memory (USS, all processes) | 169 MB | 2011 MB |
| CPU time until ready | 2.4 s | 47.9 s |
| Idle CPU | 4 % of a core | 7 % of a core |
| Quit | 0.3 s | 5.9 s |
A release build of OpenIDEA from main and IDEA with default settings and plugins, on
Windows 11, 32-core AMD, 62 GB RAM.
IDEA analyses Python more deeply, so "ready" doesn't mean the same work on
both sides. Both are measured from the outside, the same way: see
perf/compare to run it on your machine and projects.
