Update `Lib/test/support/init.py` from 3.13.5 #6037

ShaharNaveh · 2025-07-25T14:50:47Z

Summary by CodeRabbit

New Features
- The time display function now works consistently across all supported platforms, including WASI.

coderabbitai · 2025-07-25T14:50:55Z

Walkthrough

The time_ns function in the time standard library module was changed to be compiled unconditionally for all target operating systems, including wasi, by removing the previous conditional compilation attribute. The function implementation itself remains unchanged.

Changes

File(s)	Change Summary
vm/src/stdlib/time.rs	Removed `#[cfg(not(target_os = "wasi"))]` from `time_ns` function, making it always compiled.

Poem

A bunny’s clock now ticks for all,
No matter where, no build-time wall.
Nanoseconds counted, clear and free,
From WASI shores to every tree.
Time hops along with steady pace,
In every code and every place. 🐇⏳

⚡️ Unit Test Generation is now available in beta!

Chat

There are 3 ways to chat with CodeRabbit:

Review comments: Directly reply to a review comment made by CodeRabbit. Example:
- I pushed a fix in commit <commit_id>, please review it.
- Explain this complex logic.
- Open a follow-up GitHub issue for this discussion.
Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
- @coderabbitai explain this code block.
- @coderabbitai modularize this function.
PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
- @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
- @coderabbitai read src/utils.ts and explain its main purpose.
- @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
- @coderabbitai help me debug CodeRabbit configuration file.

Support

Need help? Create a ticket on our support page for assistance with any issues or questions.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

The CI fails on wasi because logging uses time.time_ns which is not available on wasi (yet).
How should I approach this? should I patch this here so we won't crash if this raises an AttributeError, or should this PR be blocked until we implement time.time_ns for wasi?

That's up to the situation. In this case, we already have _time for wasi, so it must be easy to add time_ns in wasi. (it will be inaccurate though) So I will add time_ns in this case.
If it was not easy, I would try to patch logging a little bit to ignore time_ns or to use time

This is what I ended up doing. This line was inserted 4 years ago. maybe things changed since then? now it passes for wasi 🤷 .

Usure if this is a correct fix for the issue
