… place of `?`) Summary: The first part of implementing react-native-community/discussions-and-proposals#646 to address facebook/react-native#36794. This allows Metro to respond to bundle and symbolication requests that use URLs with `//&` in place of `?` as a query delimiter. ``` **[Feature]**: Support URLs for both bundling and symbolication requests using `//&` instead of `?` as a query string delimiter ``` (Note: This does *not* add support for registering HMR entry points in the JSC-safe format - that's not necessary at this point, if at all, and I'm keen to minimise the footprint of this stack for easier backporting.)

Summary: Pull Request resolved: #989 The remaining Metro part of the implementation of react-native-community/discussions-and-proposals#646, to fix (along with an RN change): - facebook/react-native#36794 and - expo/expo#22008 This ensures that Metro always and consistently emits "JSC-safe" (i.e., `//&` query-delimited) URLs where they are used as a "source URL" for evaluated JS. This includes: - `sourceURL` within the JSON HMR payload (`HmrModule`) - `//# sourceURL` comments within the body of a base or HMR bundle - The new `Content-Location` header delivered in response to an HTTP bundle request. Clients will be expected to use these as source URL arguments to JS engines, in preference to the URL on which they might have connected/requested the bundle originally. ``` * **[Fix]**: Emit source URLs in a format that will not be stripped by JavaScriptCore ``` Reviewed By: GijsWeterings Differential Revision: D45983876 fbshipit-source-id: 3e7f0118091424b9c1b1d40e4eb7baeb5be1f48f
