[ericapisani]

Summary

• Replace requirements.txt with pyproject.toml for dependency management
• Update run.sh to use uv run instead of manual venv/pip workflow
• Part of PY-2428 migration effort

Test plan

• Run ./run.sh and verify redis-server starts and the app runs correctly

Bug: The Python version 3.11 in .python-version conflicts with the >=3.12 requirement in pyproject.toml, causing uv run to fail.
_{Severity: HIGH}

Suggested Fix

Align the Python versions. Either update the .python-version file to a version that satisfies >=3.12 (e.g., 3.12), or adjust the requires-python constraint in pyproject.toml to ">=3.11" to match the existing environment.

not valid.

Location: test-redis-asyncio/pyproject.toml#L4

Potential issue: The `pyproject.toml` file specifies a Python requirement of `>=3.12`,
while the repository's `.python-version` file is pinned to `3.11`. When `uv run` is
executed, it detects this incompatibility and exits with an error. Because the `run.sh`
script uses `set -euo pipefail`, this error will cause the entire script to terminate,
preventing the application from running.

Bug: The script installs uv but doesn't update the PATH in the current session, causing the uv run command to fail.
_{Severity: HIGH}

Suggested Fix

After the installation command, add source "$HOME/.cargo/env" or the equivalent command suggested by the uv installer's output to update the PATH for the current session. This will make the uv command available for subsequent lines in the script.

not valid.

Location: test-redis-asyncio/run.sh#L4-L6

Potential issue: When `uv` is not already installed, the `run.sh` script installs it
using `curl`. However, the installer only modifies shell configuration files (like
`~/.bashrc`) and does not add `uv` to the `PATH` for the current, running shell session.
Consequently, the subsequent `uv run` command fails with a "command not found" error.
Since the script is configured with `set -euo pipefail`, this error will halt execution
immediately.
