项目历史

Memray's README and documentation present it as a profiler for allocation tracing rather than sampling alone. It records function call stacks for allocations, can include native C/C++ frames, works with Python threads and native threads, and can be used both as a CLI and as a Python library.

The package entered public Python packaging with a 1.0.0 release on PyPI in April 2022. Its release stream continued through the 1.x line, with GitHub release notes and PyPI metadata showing active maintenance into 2026.

采用历史

Memray is distributed through Python packaging and system package managers. The upstream README links PyPI, PyPI download statistics, conda-forge, GitHub Actions for wheels, and documentation; the batch input lists apk, Homebrew, Fedora, Nix, and Arch packages. The README also points to `pytest-memray`, which brought Memray into test-suite workflows as well as ad hoc command-line profiling.

使用方式

The common CLI workflow is `python3 -m memray run -o output.bin my_script.py`, followed by a reporter such as `python3 -m memray flamegraph output.bin`. Users can also run `memray run my_script.py`, use `memray run -m my_module`, enable native tracking with `--native`, attach to processes in supported scenarios, or use the API for finer-grained profiling.

Memray is limited to Linux and macOS. Because it includes a C extension and native tooling, source builds may require dependencies such as libdebuginfod, libunwind, and liblz4, while normal users are steered toward binary wheels from PyPI.

为什么软件包爱好者会关心

Memray is notable because Python memory profiling often crosses the Python/native boundary. Packaging it means shipping compiled extensions, platform-specific wheels, and native library integration while still exposing a friendly CLI. It is also a useful package-index signal because it bridges Python developers, C-extension debugging, flamegraph tooling, and pytest integration.
