storage: Add support for temporary storage by janvarga · Pull Request #44433 · servo/servo

janvarga · 2026-04-22T11:38:06Z

Add support for temporary storage via a new config option temporary_storage
and a corresponding command-line argument --temporary-storage.

When enabled, client storage uses a storage directory
(e.g. clientstorage/temporary/<uuid>) instead of the shared default location.
This can be used to provide isolation between concurrent servo instances.

This is especially useful for WPT runs, where multiple Servo instances may
execute in parallel and would otherwise share the same storage, leading to
cross-test interference.

Based on that, this PR also updates the WPT runner to enable temporary storage
by default.

Testing: Manual testing and a full try run.

@jdm Do you think something like this would help for now?

github-actions · 2026-04-22T15:06:01Z

✨ Try run (#24782673041) succeeded.

I'm ok with this as a bandaid fix if we think that sharing storage across multiple servo processes in tests is causing issues. I think we should revert this change once we have a proper fix for using independent config directories per servo test process that is launched.

Add support for temporary storage via a new config option `temporary_storage` and a corresponding command-line argument `--temporary-storage`. When enabled, client storage uses a storage directory (e.g. `clientstorage/temporary/<uuid>`) instead of the shared default location. This can be used to provide isolation between concurrent servo instances. This is especially useful for WPT runs, where multiple Servo instances may execute in parallel and would otherwise share the same storage, leading to cross-test interference. Based on that, this patch also updates the WPT runner to enable temporary storage by default. Signed-off-by: Jan Varga <jvarga@igalia.com>

Right, I added a comment to run.py reflecting that.
This PR exists mainly to unblock #44374
