Closed Bug 1491397 Opened 2 years ago Closed 2 years ago
Script Options .script Metadata are not available
If scriptMetadata is falsey (false, 0, "", null, undefined), then the metadata is always undefined. STR: 1. Load attached extension in Nightly (including patch for bug 1437864). 2. Visit example.com Expected: - "Got expected data: 0" Actual: - "Unexpected metadata, expected 0, got undefined" This is caused by the following: https://searchfox.org/mozilla-central/rev/dd965445ec47fbf3cee566eff93b301666bda0e1/toolkit/components/extensions/ExtensionContent.jsm#650-651 const clonedMetadata = scriptMetadata ? Cu.cloneInto(scriptMetadata, apiScope) : undefined; How about just declaring clonedMetadata and then lazily cloning the metadata when needed? If the metadata is a large, rarely used object, then that would bring performance benefits.
This also adds new test coverage for the previously untested features: - "file" in "js" param to userScripts.register works. - "allFrames" set to true in userScripts.register works. - scriptMetadata accepts primitive values, and in particular falsey values in particular (= bug 1491397 ). - scriptMetadata is the same object in all API script calls.

Thank you for the test extension and STR. Validated the fix as per expected results from the description using the provided extension on: latest Nightly: 65.0a1 running on Windows 10 x64 and Nightly on Ubuntu 18.04.
