webdriver: Wait indefinitely with `None` timeout by yezhizhen · Pull Request #42184 · servo/servo

yezhizhen · 2026-01-27T11:15:05Z

So far for None timeout, we've treated it effectively as no wait which is wrong: web-platform-tests/wpt#57332 (comment).

This PR makes all None timeouts wait indefinitely. The funny part is, we somehow have only done it correctly for pageload: https://w3c.github.io/webdriver/#dfn-timeouts-configuration

Testing: We add test for script execution with None script timeout.

Waiting for upstream review for tests.
Somehow Firefox is failing this, which I believe is another bug: web-platform-tests/wpt#57403 (comment)

So far for `None` [timeout](https://w3c.github.io/webdriver/#dfn-timeouts-configuration), we've treated it effectively as no wait which is wrong: web-platform-tests/wpt#57332 (comment). This PR makes all `None` timeouts wait indefinitely. The funny part is, we somehow have only done it correctly for `pageload`: https://w3c.github.io/webdriver/#dfn-timeouts-configuration Testing: We add test for script execution with `None` script timeout. --------- Signed-off-by: Euclid Ye <[email protected]>
