* zlib: clear unconsumed_tail when a bounded decompress reaches stream end When a max_length-bounded Decompress.decompress() call reached the end of the stream, the bytes after the stream went to unused_data, but unconsumed_tail kept the previous call's tail, including input the call had already consumed. A later flush() then moved those stale bytes into unused_data. Empty unconsumed_tail at end of stream, as CPython's save_unconsumed_input() does since gh-158169. CPython releases before that change report the bytes after the stream in unconsumed_tail, so the snippet accepts either value when it runs under CPython. Fixes #8906 Assisted-by: Claude Code:claude-opus-5-5 * zlib: bind the unconsumed input with an if expression Choose between the empty slice and the rest of the input in one expression instead of reassigning a mutable binding. Assisted-by: Claude Code:claude-opus-5-5 * zlib: accept both valid tails in the snippet on every implementation The snippet no longer branches on sys.implementation. RustPython and CPython after gh-158169 give an empty tail; CPython before it gives the bytes after the stream. The stale tail of gh-8906 fails either way. Assisted-by: Claude Code:claude-opus-5-5
Test snippets
This directory contains two sets of test snippets which can be run in Python.
The snippets/ directory contains functional tests, and the benchmarks/
directory contains snippets for use in benchmarking RustPython's performance.
Setup
Our testing depends on pytest, which you can install using pip.
Running
Simply run pytest -v in this directory, and the tests should run (and hopefully
pass). If it hangs for a long time, that's because it's building RustPython in
release mode, which should take less time than it would to run every test
snippet with RustPython compiled in debug mode.
