Add “Copy Logs” Button to Task Log Viewer in Airflow 3.0 UI

[munnch]

Description

Feature Description

Airflow’s Task Instance Log page currently displays logs but offers no one-click way to copy them. Users must manually select and copy text, which is error-prone—especially for long logs or when searching for specific patterns. Adding a “Copy Logs” button would allow users to copy the entire log (or filtered portion) to their clipboard with one click.

Proposed Solution

UI Changes

• Add a “Copy Logs” icon/button next to existing log-controls (e.g., alongside the 'Wrap' button).
• Button tooltip: “Copy full log to clipboard”.

Use case/motivation

Use Cases

• Debugging locally or in CI
  Users reviewing logs in the Airflow UI often need to paste them into issue trackers, Slack, or local editors for deeper analysis or sharing with team members.

• Automated processing
  When building integrations (e.g. alerting scripts or external dashboards), having an easy way to programmatically copy logs via the browser can speed up development.

• Accessibility
  A dedicated button reduces reliance on precise mouse-drag selection, aiding users on touch devices or those who use keyboard navigation and screen readers.

If you're looking to build something programmatic, you can hit the API to retrieve logs!

@jroachgolf84 good catch – tbh my main use case is i've been highlighting task log messages a million times in order to copy and paste into and LLM and say "plz fix"

I feel like a download button would also handle that use case? #49412

I want to be able to quickly get the log in my clipboard to past into a chat window, I don't think the download logs would be super helpful for my use case cause I'd have to download, open it up, copy that file. I just want a quick and easy way to copy the log message. I also end up highlighting log messages a lot to send in messages over Slack when debugging async with others. For me, it would be extremely helpful to have a better way to copy log messages from the UI than trying to highlight things in my browser.

I still think we should add the Download Logs button first. And I think that specific use case would be better handled with custom UI plugins in 3.1.0
